Description

Technical Field

[0001] The present disclosure relates to a cooking appliance, and more particularly, to a cooking appliance that provides both a cooking function and a fume extraction function. Background Art

[0002] A cooking appliance is a household device used for cooking food and is a device installed in a kitchen space to cook food according to a user's intention. Such cooking appliances can be variously classified according to the type of heat source, form, or fuel to be used.

[0003] When classifying cooking appliances according to the type of food being cooked, cooking appliances can be classified into open cooking appliances and closed cooking appliances according to the type of space for placing food. Closed cooking appliances include ovens, microwave ovens, etc., and open cooking appliances include cooking ranges, stoves, etc.

[0004] A closed cooking appliance is a cooking appliance that shields the space where food is located and heats the shielded space to cook food. In a closed cooking appliance, a chamber (i.e., a cooking chamber) is provided inside the main body, and the chamber is a space that is shielded while cooking food when food is placed therein. Such a cooking chamber becomes a substantially space for cooking food. A heat source is provided in the internal space or external space of the cooking chamber to heat the cooking chamber.

[0005] A microwave oven of a closed cooking appliance is a cooking device that uses electricity to generate microwaves to penetrate an object to be cooked accommodated in a cooking chamber, thereby heating the object to be cooked by causing molecular motion therein.

[0006] A microwave oven is a kitchen device that simultaneously heats the inside and outside of food by irradiating high-frequency waves of a magnetron to food, and is widely used due to the following advantages: such as significantly shortening the cooking time of food due to high thermal efficiency, reducing the loss of nutritional value during the cooking, thawing, and heating processes of food, and being able to directly cook while storing food in a container.

[0007] Recently, a microwave oven with a fume extraction function combined with a fume extractor, also called an OTR (Over-the-Range, top-mounted) type microwave oven, has been released. The OTR type microwave oven with a fume extractor has a function of discharging air containing foreign substances (hereinafter referred to as "cooking gas") generated during the process of cooking food from a cooking appliance installed below it, or filtering the cooking gas and then discharging the filtered gas to the inside.

[0008] A fan for sucking and discharging air is provided in a microwave oven combined with a fume extractor. Such a fan is usually provided on the top of a cavity that defines a cooking chamber. That is, in a microwave oven with a fume extractor, the fan is usually provided on the top of the cavity.

[0009] However, when the fan is set at the position as described above, the distance between the fan and the suction hole provided at the lower end of the microwave oven combined with the range hood is greater than the vertical length of the cavity. As described above, the increase in the distance between the suction hole and the fan inevitably reduces the cooking gas collection performance of the microwave oven with the range hood. This is because the flow velocity of the suction air flow generated by the fan may decrease in a manner inversely proportional to the square of the distance from the fan to the suction hole.

[0010] In addition, when the fan is set at the above position, the overall vertical length of the microwave oven combined with the range hood is inevitably increased. Therefore, when the microwave oven combined with the range hood having an increased vertical length is installed in the upper cabinet, the possibility that the microwave oven combined with the range hood protrudes downward beyond the upper cabinet increases.

[0011] When the microwave oven with the range hood protrudes downward beyond the upper cabinet, its aesthetics are poor, and there may be a problem of a small distance between the stove installed below the upper cabinet and the microwave oven with the range hood.

[0012] When the distance between the stove and the microwave oven with the range hood is small as the microwave oven with the range hood protrudes downward beyond the upper cabinet, there may be problems such as the microwave oven with the range hood blocking the view of the user who wants to use the stove and a small cooking area of the stove. Summary of the Invention

[0063] Technical Effects

[0064] The cooking appliance of the present disclosure is configured such that a blower for providing a fume extraction function is provided at the rear of the cavity instead of above the cavity, thereby suppressing an increase in the length of the cooking appliance in the vertical direction and simultaneously providing a fume extraction function.

[0065] In addition, according to the present disclosure, the blower may be provided in the rear space for ensuring a space for installing a convection module or the like instead of in the upper space and the side space defined inside the main body, thereby reducing the vertical length of the cooking appliance and effectively suppressing an increase in the vertical and lateral lengths of the cooking appliance, thereby effectively suppressing an increase in the vertical and lateral lengths of the cooking appliance and simultaneously providing a fume extraction function with improved performance.

[0066] In addition, the cooking appliance of the present disclosure adopts a structure in which a blower is disposed in a rear space, and the rear space is connected to an exhaust hole and aligned with the exhaust hole in a straight line, thereby minimizing the air flow loss inside the cooking appliance, and thus further improving the cooking gas removal performance.

[0067] In addition, in the cooking appliance of the present disclosure, the exhaust flow path defined by the flow path defining member can smoothly induce the exhaust air flow while reducing the resistance of the flow path around the exhaust hole, thereby effectively improving the cooking gas discharge performance.

[0068] In addition, according to the present disclosure, the force provided by the suction of the fan assembly can be applied to the electronic / electrical component chamber through the connection flow path, thereby allowing the air flow in the electronic / electrical component chamber to proceed more smoothly, so that the electronic / electrical components provided in the electronic / electrical component chamber can be cooled more effectively.

[0069] In addition, the cooking appliance of the present disclosure allows the air introduced into the electronic / electrical component chamber to flow from the electronic / electrical component chamber into the fan assembly through the connection flow path, thereby effectively increasing the suction flow rate of the fan assembly, thereby providing more improved cooking gas removal performance.

[0070] In addition, according to the present disclosure, the extension plate that divides the side space into upper and lower parts can increase the total size of the exhaust space, thereby effectively increasing the size of the flow path required for the air flow discharged into the exhaust hole through the exhaust space.

[0071] In addition, according to the present disclosure, since the extension plate vertically divides the side space, each of the space related to gas discharge and the space related to air inhalation can be ensured to have a sufficient size required for inhalation or discharge. Therefore, the cooking appliance of the present embodiment can provide cooking gas removal performance equal to or higher than that of a conventional cooking appliance having a similar cooking ability, while having a total size smaller than that of a conventional cooking appliance having a similar cooking ability.

[0072] Furthermore, the cooking appliance of the present disclosure is configured to allow both the steam and gas discharged from the cooking chamber and the cooking gas sucked by the blower to be discharged through a common exhaust hole, thereby effectively increasing the area of the exhaust hole for gas discharge, and thus discharging the cooking gas more smoothly through the exhaust hole.

[0073] Furthermore, the cooking appliance of the present disclosure may include an exhaust duct formed in a structure in which its vertical length decreases as the exhaust duct extends rearward, thereby effectively suppressing an increase in flow resistance caused by the exhaust duct while smoothly discharging the steam and gas discharged from the cooking chamber to the outside of the cooking appliance.

[0074] In addition, the cooking appliance of the present disclosure allows the exhaust duct to be detachably coupled to a duct bracket joined to the cavity, thereby allowing the exhaust duct to be easily and quickly removed from the cavity as needed and suppressing the occurrence of cavity damage that may occur during the process of disassembling and reassembling the exhaust duct.

[0075] In addition, the cooking appliance of the present disclosure includes a rear support member that serves to stably hold the posture of the cavity such that the cavity does not tip backward during the assembly process of the cooking appliance, thereby enabling the assembly of the cooking appliance to be conveniently performed in a relatively stable environment and suppressing the occurrence of various safety accidents that may occur due to the tipping of the cavity during the assembly process of the cooking appliance.

[0076] Furthermore, since the rear support member installed at the rear side of the cavity stably supports the rear plate and the bottom plate on the cavity, the cooking appliance of the present disclosure can effectively improve the structural stability of the cooking appliance.

[0077] In addition, the cooking appliance of the present disclosure maintains the interval between the cavity and the rear plate via the rear support member, such that sufficient space required for air flow in the rear space can be ensured, thereby effectively increasing the suction flow rate.

[0078] In addition, the cooking appliance of the present disclosure includes a shielding member that shields the lower electronic / electrical component chamber while being located on top of the lower electronic / electrical component chamber, thereby allowing air to smoothly flow into the lower electronic / electrical component chamber and simultaneously significantly reducing the risk of fire spread due to a flame generated inside the cooking appliance.

[0079] In addition, the cooking appliance of the present disclosure includes a lamp cover that covers the lamp while being located on top of the lamp, thereby serving the purpose of reducing the vertical length of the cooking appliance and the purpose of protecting the lamp from oil vapor and heat.

[0080] In addition, the lamp cover according to the present disclosure is configured such that its vertical length decreases as the lamp cover extends toward the rear side, such that the lamp can be effectively protected from oil vapor and heat, and at the same time, an increase in flow resistance caused by the lamp cover can be effectively suppressed.

[0081] In addition, according to the present disclosure, a simple operation of removing the ventilation grille and the on / off cover allows the user to access the lamp, thereby enabling the maintenance and repair of the lamp to be performed in a simple and quick manner.

[0174] The first exhaust hole 2 can be provided in the rear part of the upper surface of the main body 10. Additionally, the second exhaust hole 3 can be provided on the front side of the upper surface of the main body 10. That is, the second exhaust hole 3 can be provided on the side adjacent to the door 20 and can be provided closer to the front side than the first exhaust hole 2.

[0175] The first exhaust hole 2 can constitute a passage for discharging the cooking gas sucked into the cooking appliance to the outside. The second exhaust hole 3 can constitute a passage for discharging the cooking gas sucked into the cooking appliance to the indoor space.

[0176] In one example, the first exhaust holes 2 may be provided in a region that vertically overlaps with the upper cabinet that houses the cooking appliance. Additionally, the second exhaust holes 3 may be provided at a position that protrudes forward beyond the upper cabinet.

[0177] Additionally, the first exhaust holes 2 may be generally provided at the center in the lateral direction of the main body 10. Additionally, a plurality of second exhaust holes 3 may be provided in the lateral direction and may be positioned on the front side of the upper surface of the main body 10.

[0178] The first exhaust holes 2 provided as described above at the generally center in the lateral direction of the main body 10 may be connected to an exhaust duct connected to the outside. The plurality of laterally arranged second exhaust holes 3 may discharge the cooking gas from a position in front of the upper cabinet to a position above the cooking appliance. In this regard, the cooking gas may be discharged through the second exhaust holes 3 in a state where it is filtered inside the cooking appliance.

[0179] Similar to the first exhaust holes 2, the third exhaust holes 4 may constitute a passage for discharging the cooking gas sucked into the cooking appliance to the outside. The third exhaust holes 4 may be provided to face the wall surface on which the cooking appliance is mounted. The third exhaust holes 4 may be installed on the rear surface of the main body and may be connected to an exhaust duct connected to the outside.

[0180] The third exhaust holes 4 may be defined in the rear surface of the cooking appliance and may be provided above the blowers 100 and 200. In one example, the third exhaust holes 4 may be defined in the rear plate 15. The third exhaust holes 4 may be formed to extend through the rear plate 15 in the front - rear direction.

[0181] A space may be formed in the main body 10. The space may be provided between the cavity 11 and the cabinet 13.

[0182] The space may be divided into a side space 10e and a rear space 10f. The side space 10e may be provided on each of two opposite sides in the lateral direction of the cavity 11. Additionally, the rear space 10f may be provided on the rear side of the cavity 11.

[0183] For example, each side space 10e may be a space defined between each side surface of the cavity 11 and each side surface of the cabinet 13. Additionally, the rear space 10f may be a space defined between the rear surface of the cavity 11 and the rear plate 15.

[0184] The side space 10e and the rear space 10f can communicate with the lower space. The side space 10e and the rear space 10f can be connected to the lower space in the vertical direction, or can be connected to the lower space in the lateral direction. The air inlet hole 1 can communicate with the lower space. The side space 10e and the rear space 10f can communicate with the air inlet hole 1 through the lower space.

[0185] The electronic / electrical component chambers 10b, 10c, and 10d can be provided in one of the side spaces in the side space 10e. In the present embodiment, the case where the electronic / electrical component chambers 10b, 10c, 10d are provided in the side space behind the control panel 25 is illustrated.

[0186] In addition, a space provided on the side surface and the rear side of the cavity 11 can be defined inside the main body 10. This space can be the rear space 10f, the side space 10e, or can be the electronic / electrical component chambers 10b, 10c, and 10d.

[0187] For example, this space can be provided in the rear corner portion inside the main body 10. Hereinafter, the space provided behind the electronic / electrical component chambers 10b, 10c, 10d is referred to as the corner space 10e. The rear space 10f and the side space 10e, more specifically, the rear space 10f and the electronic / electrical component chambers 10b, 10c, 10d can communicate with each other through the corner space 10e.

[0188] The blowers 100 and 200 can be provided inside the main body 10. More specifically, the blowers 100 and 200 can be provided in the space, that is, the space between the cavity 11 and the casing 13. The blowers 100 and 200 can include at least one fan assembly 100 and 200.

[0189] The fan assemblies 100 and 200 can generate an air flow for sucking the cooking gas to the outside of the cooking appliance and discharging the cooking gas to the outside of the cooking appliance. The fan assemblies 100 and 200 can introduce the cooking gas into the main body 10 through the air inlet hole 1 and discharge the introduced cooking gas out of the main body through the exhaust holes 2, 3, and 4.

[0190] At least one of the fan assemblies 100 and 200 provided in the blowers 100 and 200 can be provided in the rear space 10f. Therefore, the cooking gas introduced into the main body 10 through the air inlet hole 1 can flow through the rear space 10f and then be discharged through the first exhaust hole 2 or the second exhaust hole 3. The detailed setting structure of the fan assemblies 100 and 200 will be described later.

[0191] In addition, an upper space 10i can be further provided inside the main body 10. The upper space 10i can be provided above the cavity 11.

[0192] For example, the upper space 10i may be defined between the upper surface of the cavity 11 and the upper surface of the cabinet 13. The upper space 10i may communicate with the rear space 10f.

[0193] That is, the air introduced into the rear space 10f may flow through the upper space 10i and be discharged to the outside of the cooking appliance through the exhaust holes 2, 3, and 4. Additionally, the air introduced into the side space 10e may also flow through the rear space 10f and the upper space 10i, and may be discharged to the outside of the cooking appliance through the exhaust holes 2, 3, and 4.

[0194] [Fan assembly]

[0195] Figure 8 Is a perspective view showing the rear fan assembly separated from the Figure 6 shown cooking appliance, Figure 9 Is a perspective view showing the corner fan assembly separated from the Figure 6 shown cooking appliance.

[0196] Referring to Figure 1 and Figures 7 to 8 , the blowers 100 and 200 may include at least one fan assembly 100 and 200. In one example, the blowers 100 and 200 may include the rear fan assembly 100.

[0197] The rear fan assembly 100 may include a fan housing 110, an impeller 120, and a fan motor.

[0198] The fan housing 110 forms the appearance of the rear fan assembly 100 and houses the impeller 120 therein. The first suction hole 112 may be formed on the side of the fan housing 110. The first suction hole 112 may constitute a passage for sucking the air outside the rear fan assembly 100 into the impeller 120 inside the fan housing 110.

[0199] In the present embodiment, the fan housing 110 is shown to be formed in a shape including a horizontally extending cylindrical shape, where both opposite sides of the fan housing are open, and each of the two opposite open sides of the fan housing 110 may be provided with the first suction hole 112.

[0200] A receiving space for housing the impeller 120 may be formed inside the fan housing 110.

[0201] This receiving space for housing the impeller 120 may be formed inside the fan housing 110. Additionally, the inner circumferential surface of the fan housing 110 defining the receiving space may be formed as a curved surface surrounding the outer circumferential surface of the impeller 120.

[0202] On the upper side of the fan housing 110, a first discharge hole 114 may be provided. The first discharge hole 114 constitutes a passage through which air sucked into the accommodation space housing the wind wheel 120 is discharged to the outside of the blowers 100 and 200.

[0203] The first discharge hole 114 may be formed to penetrate the fan housing 110 in the vertical direction. Thus, the air sucked into the interior of the fan housing 110 from the lateral direction through the first suction hole 112 can be discharged to a position above the top of the fan housing 110 through the first discharge hole 114.

[0204] The wind wheel 120 is configured to rotate about an axis extending in the lateral direction. A space is formed inside the wind wheel 120 for air sucked through the side portion of the wind wheel 120 to flow in.

[0205] The wind wheel 120 may be connected to the rotating shaft of the fan motor. The rotating shaft of the fan motor rotates about an axis extending in the lateral direction, and the wind wheel 120 connected to the rotating shaft of the fan motor can rotate together with the rotating shaft of the fan motor about an axis extending in the lateral direction.

[0206] The rear fan assembly 100 configured as described above may be provided inside the main body 10 and may be provided in at least one of the rear space 10f and the corner space 10e. In the present embodiment, the rear fan assembly 100 is shown provided in the rear space 10f.

[0207] In one example, the rear fan assembly 100 may be provided in a form including a pair of wind wheels 120. The rear fan assembly 100 may be provided in a form in which the fan motor is disposed between a pair of wind wheels 120 disposed in the lateral direction.

[0208] In the rear fan assembly 100, the fan motor may cause a pair of wind wheels 120 respectively disposed on two opposite sides in its lateral direction to rotate together. Each wind wheel 120 may be accommodated in each of a pair of fan housings 110 respectively disposed on two opposite sides in the lateral direction of the fan motor.

[0209] As described above, the rear fan assembly 100 including one fan motor, a pair of wind wheels 120, and the fan housing 110 can suck air through a pair of first suction holes 112 respectively disposed on two opposite sides in the lateral direction of the rear fan assembly 100, and discharge air through a pair of first discharge holes 114 disposed in the upper surface of the rear fan assembly 100 and extending in the lateral direction.

[0210] The rear fan assembly 100 can be arranged in the following form: a pair of impellers 120 are respectively arranged on two opposite sides in the lateral direction of the fan motor, and a pair of fan housings 110 are respectively arranged on two opposite sides in the lateral direction of the fan motor. Hereinafter, the assembly of the impeller 120 and the fan housing 110 is referred to as a "fan module". In this regard, the rear fan assembly 100 can be arranged in a form where a pair of fan modules are connected to two opposite sides in the lateral direction of the fan motor.

[0211] The rear fan assembly 100 can be arranged in the rear space 10f, that is, in the space defined between the rear surface of the cavity 11 and the rear plate 15. The rear fan assembly 100 can be arranged in a space communicating with the air intake hole 110 and the exhaust holes 2, 3, and 4, and can suck air through the air intake hole 110 and discharge air toward the exhaust holes 2, 3, and 4.

[0212] In addition, the rear fan assembly 100 can be arranged at the center in the lateral direction of the rear space 10f. That is, the rear fan assembly 100 can be arranged approximately at the center of the rear side inside the cooking appliance.

[0213] According to this embodiment, the first exhaust hole 2 can be approximately arranged at the center in the lateral direction of the main body 10, and can be defined in the upper surface of the box body 13, and can be located at a position closer to its rear end. In addition, the first exhaust hole 2 can be arranged in an area overlapping with the fan assemblies 100 and 200 in the vertical direction. That is to say, the first exhaust hole 2 can be arranged in an area overlapping with the rear space 10a and the rear fan assembly 100 in the vertical direction.

[0214] In addition, the third exhaust hole 4 can be arranged at approximately the center in the lateral direction of the main body 10, and can be arranged in the rear plate 15 and at a position closer to the upper end of the rear plate 15. That is to say, the third exhaust hole 4 can be arranged in the rear surface of the main body 10, but can be arranged at a position adjacent to the first exhaust hole 2.

[0215] In the cooking appliance according to this embodiment, the first exhaust hole 2, the third exhaust hole 4, and the rear fan assembly 100 can all be arranged in the rear space 10f. The first exhaust hole 2 and the third exhaust hole 4, especially the first exhaust hole 2, can be aligned with the rear fan assembly 100 in the vertical direction along the rear space 10f.

[0216] That is to say, the rear fan assembly 100, the rear space 10f, the first exhaust hole 2, and the third exhaust hole 4 can overlap with each other in the vertical direction. Preferably, the rear fan assembly 100, the rear space 10f, the first exhaust hole 2, and the third exhaust hole 4 can be aligned with each other in a line along the vertical direction.

[0217] Therefore, the air flow performed through the operation of the rear fan assembly 100 may have a linear direction that is the same as the direction in which the rear fan assembly 100, the rear space 10f, the first exhaust hole 2, and the third exhaust hole 4 are aligned with each other.

[0218] When the air flows in the linear direction as described above, the resistance to the air flow is reduced, enabling the air flow to proceed more smoothly. Therefore, the air intake and discharge performance of the rear fan assembly 100 can be improved, and accordingly, the cooking gas removal performance of the cooking appliance can be enhanced.

[0219] The blowers 100 and 200 of the present embodiment may include a plurality of fan assemblies 100 and 200 arranged in the lateral direction. In one example, the blowers 100 and 200 may further include corner fan assemblies 200, as Figure 7 and Figure 9 shown. The rear fan assembly 100 and the corner fan assembly 200 may be arranged laterally and disposed in the rear space 10f.

[0220] The corner fan assembly 200 may be provided in the form of a single fan module connected to a fan motor. In one example, the corner fan assembly 200 may be disposed in a configuration where a single fan module is connected to the lower side of the fan motor.

[0221] In the corner fan assembly 200, the impeller 220 may rotate about a vertical axis. The second intake hole 212 may be provided in the lower surface of the fan housing 210, and the second discharge hole 224 may be provided at the side surface of the fan housing 210.

[0222] That is, the corner fan assembly 200 may be arranged in a configuration similar to a configuration in which approximately half of the rear fan assembly 100 stands upright in the vertical direction.

[0223] The rear fan assembly 100 and the corner fan assembly 200 may be provided together in the rear space 10f. In one example, the rear fan assembly 100 and the corner fan assembly 200 may be arranged laterally and disposed in the rear space 10f.

[0224] For example, the corner fan assembly 200 may be disposed adjacent to the electronic / electrical component chambers 10b, 10c, and 10d on one side of the main body, while the rear fan assembly 100 may be disposed adjacent to the side space 10e on the other side of the main body.

[0225] At least a part of the corner fan assembly 200 may be disposed in the corner space 10e. In one example, most of the area of the corner fan assembly 200 may be disposed in the corner space 10e, and the second intake hole 212 of the corner fan assembly 200 may also be disposed in the corner space 10e. The corner fan assembly 200 may be configured to be spaced apart from the rear fan assembly 100 by a predetermined distance in the lateral direction.

[0226] According to the present embodiment, the blowers 100 and 200 may include the rear fan assembly 100 and the corner fan assembly 200 together, rather than including only a plurality of rear fan assemblies 100.

[0227] Since both the rear fan assembly 100 and the corner fan assembly 200 are applied to the blowers 100 and 200, the total lateral length of the blowers 100 and 200 can be reduced compared to the case where the blowers 100 and 200 include only a plurality of rear fan assemblies 100.

[0228] For example, the lateral length of the blowers 100 and 200 including one rear fan assembly 100 and one corner fan assembly 200 can be measured to be shorter than the lateral length of the blower 200 including a pair of rear fan assemblies 100 arranged in the lateral direction.

[0229] The corner fan assembly 200 may include only one of the fan modules included in the rear fan assembly 100, and may include a fan module erected in the vertical direction. Therefore, the lateral length of the corner fan assembly 200 is necessarily shorter than the lateral length of the rear fan assembly 100.

[0230] Considering this configuration, the blowers 100 and 200 of the present embodiment including the corner fan assembly 200 can be set to a much smaller size than the rear fan assembly 100 or a blower including only the rear fan assembly 100.

[0231] When this type of blower 100 or 200 is applied to a cooking appliance, the size of the cooking appliance, particularly the lateral length of the cooking appliance, can be reduced as the space occupied by the blower 100 or 200 decreases.

[0232] Considering this, when the size of the cooking appliance is small such that a plurality of rear fan assemblies 100 are not accommodated inside the cooking appliance, the blowers 100 and 200 of the present embodiment are very suitable for application to the cooking appliance.

[0233] In addition, in the corner fan assembly 200, the second suction hole 212 may be provided on the lower surface of the fan housing 210. Therefore, the second suction hole 212 can be provided at the lowermost end of the corner fan assembly 200, and can be provided at a position very close to the air intake hole 1 provided at the lower end of the cooking appliance.

[0234] Considering that the suction performance of the fan assembly based on the output of the fan motor can be greatly improved as the distance between the second suction hole 212 and the air intake hole 1 becomes smaller, it can be determined that the suction performance of the corner fan assembly 200 can be significantly improved as the second suction hole 212 of the corner fan assembly 200 is closer to the air intake hole 1.

[0235] That is to say, the performance of the corner fan assembly 200 may be lower than that of the rear fan assembly 100, but this performance difference may be mostly offset by the performance improvement value obtained due to the reduced distance between the second suction hole 212 and the air intake hole 1.

[0236] Considering this fact, it can be evaluated that the blowers 100 and 200 of the present embodiment can provide an effect conducive to the miniaturization of the cooking appliance while providing the same or higher cooking gas removal performance as another type of blower.

[0237] The cooking appliance of the present embodiment including the blowers 100 and 200 can provide improved cooking gas removal performance while maintaining a compact size.

[0238] In addition, with reference to Figures 5 to 7 , the rear fan assembly 100 and the corner fan assembly 200 can be positioned to overlap the cavity 11 in the front-rear direction. That is, the rear fan assembly 100 and the corner fan assembly 200 can be disposed between the upper surface and the lower surface of the cavity 11 in the vertical direction.

[0239] In order to enable the air introduced into the main body 10 through the air intake hole 1 to flow smoothly to the rear fan assembly 100 or the corner fan assembly 200, a certain distance should be ensured between the rear fan assembly 100 and the corner fan assembly 200 and the air intake hole 1.

[0240] In addition, in order to enable the air discharged from the rear fan assembly 100 and the corner fan assembly 200 to flow smoothly into the upper space 10i, the rear fan assembly 100 and the corner fan assembly 200 are disposed at a height lower than that of the upper space 10i.

[0241] When the rear fan assembly 100 and the corner fan assembly 200 are disposed at a position higher than the upper space 10i, there may be a problem that the passage between the first discharge hole 114 of the rear fan assembly 100 or the second discharge hole 214 of the corner fan assembly 200 and the upper space 10i is too narrow.

[0242] Considering this situation, in the present embodiment, the rear fan assembly 100 and the corner fan assembly 200 are disposed at positions such that the rear fan assembly 100 and the corner fan assembly 200 can be appropriately spaced apart from the air intake hole 1 and the rear fan assembly 100 and the corner fan assembly 200 can be appropriately spaced apart from the upper space 10i.

[0243] Therefore, the air flow from the air intake hole 1 to the rear fan assembly 100 and the corner fan assembly 200 and the air flow from the rear fan assembly 100 and the corner fan assembly 200 to the upper space 10i can proceed smoothly.

[0244] In addition, the corner fan assembly 200 may be disposed at a position closer to the air intake hole 1 than the exhaust holes 2, 3, and 4. Accordingly, the second suction hole 212 of the corner fan assembly 200 may be disposed at a position very close to the air intake hole 1. As a result, compared with the rear fan assembly 100, the suction performance of the corner fan assembly 200 having a relatively small size and low output can be effectively improved.

[0245] [An example of the flow path defining member]

[0246] Figure 10 is a rear perspective view of a flow path defining member separated from a cooking appliance as shown in Figure 6 shown. Figure 11 is a rear perspective view of a cooking appliance to which another example of the flow path defining member is applied. Figure 12 is a rear perspective view of a flow path defining member separated from a cooking appliance as shown in Figure 11 shown, and Figure 13 is a rear view showing an air flow state in a cooking appliance according to a first embodiment of the present disclosure.

[0247] Referring to Figures 5 to 7 and Figure 10 , the cooking appliance may include a flow path defining member 30. The flow path defining member 30 is configured to induce the flow of air discharged from the blowers 100 and 200.

[0248] The flow path defining member 30 may define an exhaust flow path A inside the cooking appliance. The exhaust flow path A may connect the blowers 100 and 200 to the upper space 10i with each other, and may guide air from at least one of the rear fan assembly 100 and the corner fan assembly 200 to the upper space 10i. The exhaust flow path A may guide the air discharged from the blowers 100 and 200 to flow toward the exhaust holes 2, 3, and 4.

[0249] In one example, the exhaust flow path A may be disposed in the rear space 10f. The inlet of the exhaust flow path A may be opened toward the blowers 100 and 200. For example, the inlet of the exhaust flow path A may be opened toward the first discharge hole 114 of the rear fan assembly 100 and the second suction hole 214 of the corner fan assembly 200. The outlet of the exhaust flow path A may be opened toward the upper space 10i.

[0250] The exhaust flow path A may be formed inside the cooking appliance, and may constitute a flow path for guiding the air flow from the first discharge hole 114 of the rear fan assembly 100 to the upper space 10i. In addition, the exhaust flow path A may be formed inside the cooking appliance, and may constitute a flow path for guiding the air flow from the second suction hole 214 of the corner fan assembly 200 to the upper space 10i.

[0251] In one example, at least a portion of the exhaust flow path A can be defined by the first flow path plate 31. The first flow path plate 31 can form a wall that blocks the first suction hole 112 and the first discharge hole 114 of the rear fan assembly 100.

[0252] The first flow path plate 31 can be disposed in the rear space 10f and can be disposed above the rear fan assembly 100. That is, the first flow path plate 31 can form a wall that blocks the first suction hole 112 and the first discharge hole 114 such that the wall is located above the rear fan assembly 100.

[0253] According to the present embodiment, the rear fan assembly 100 and the corner spaces 10g and 10h can be laterally disposed and disposed in the rear space 10f. In the rear space 10f, the first suction holes 112 can be respectively disposed on two lateral sides of the rear fan assembly 100. The first discharge hole 114 is disposed between a pair of first suction holes 112 that are spaced apart by a predetermined distance in the lateral direction and is formed on the upper surface of the rear fan assembly 100.

[0254] In a case where the first suction hole 112 that is closer to the corners 10g and 10h among the pair of first suction holes 112 is referred to as the left first suction hole 112, the first flow path plate 31 is configured as a wall that blocks the first discharge hole 114 and the right first suction hole 112. The first flow path plate 31 can be disposed around the lateral center of the rear fan assembly 100 at a position closer to the right first suction hole 112, that is, at a position adjacent to the right first suction hole 112.

[0255] Hereinafter, the direction along the lateral direction around the lateral center of the cooking appliance toward the electronic / electrical component chambers 10a, 10c, and 10d will be referred to as the left direction, and the direction toward the side space 10e located on the opposite side thereof will be referred to as the right direction.

[0256] The first flow path plate 31 can form a vertical wall that extends upward from the upper surface of the rear fan assembly 100 where the first discharge hole 114 is formed toward the upper space 10i. The first flow path plate 31 can define the right boundary surface of the exhaust flow path A.

[0257] The cooking appliance of the present embodiment can further include an extension plate 18. The extension plate 18 can be disposed to block the upper space 10i and the rear space 10f.

[0258] At least a portion of the extension plate 18 can be disposed in the rear space 10f. At least a portion 18b of the extension plate 18 disposed in the rear space (hereinafter referred to as the "rear partition portion") can be disposed between the rear fan assembly 100 and the upper space 10i in the vertical direction. In addition, the rear partition portion 18b of the extension plate 18 can be disposed between the rear surface of the cavity 11 and the rear plate 15 in the front-rear direction.

[0259] The rear partition portion 18b of the extension plate 18 arranged as above covers a part of the rear space 10f while being arranged at a position higher than the position of the rear fan assembly 100, and blocks a part of the rear space 10f from the upper space 10i.

[0260] In the present embodiment, a case is shown where the right region of the rear space 10f and the upper space 10i are blocked from each other via the extension plate 18.

[0261] The extension plate 18 and the rear fan assembly 100 are arranged at a distance in the vertical direction. Therefore, a lateral flow path is formed between the extension plate 18 and the rear fan assembly 100. The lateral channel thus formed can connect the right region of the rear space 10f covered by the extension plate 18 and the region defining the exhaust flow path A above the rear fan assembly 100 to each other.

[0262] The first flow path plate 31 can form a vertical wall extending upward from the rear fan assembly 100 toward the extension plate 18. In one example, the first flow path plate 31 can form a vertical wall connecting the upper surface of the rear fan assembly 100 and the side end of the extension plate 18. At least a part of the first flow path plate 31 can protrude upward beyond the extension plate 18.

[0263] As described above, the first flow path plate 31 connected to the extension plate 18 can form a vertical wall that blocks the lateral channel defined between the rear fan assembly 100 and the extension plate 18. That is, the first flow path plate 31 can form a wall that blocks the air flow between the right region of the rear space 10f and the exhaust flow path A, such that the wall is located in the rear space 10f.

[0264] The flow path defining member 30 may also further include a second flow path plate 32. The second flow path plate 32 can form a wall that blocks the first suction hole 112 and the first discharge hole 114 of the rear fan assembly 100 from each other.

[0265] The second flow path plate 32 can be arranged on the left side of the rear fan assembly 100. Therefore, the rear fan assembly 100 can be arranged between the first flow path plate 31 and the second flow path plate 32 in the lateral direction.

[0266] In the lateral direction, the second flow path plate 32 can be arranged between the rear fan assembly 100 and the corner fan assembly 200. The second flow path plate 32 can form a wall that blocks the first suction hole 112 and the first discharge hole 114 from each other, and at the same time forms a wall that blocks the second suction hole 214 of the corner fan assembly 200 and the first suction hole 112 of the rear fan assembly 100 from each other.

[0267] In the corner fan assembly 200, the second suction hole 212 is oriented towards the air intake hole 1, i.e., downward. The second suction hole 214 can be arranged to face the rear fan assembly 100, i.e., horizontally, and more specifically, towards the right side, and can be connected to the exhaust flow path A.

[0268] The second flow path plate 32 can be arranged on the right side of the second suction hole 214 to define the lower boundary surface of the exhaust flow path A. The second flow path plate 32 is arranged between the rear fan assembly 100 and the corner fan assembly 200 and forms the lower boundary surface of the exhaust flow path A. In this regard, the lower boundary surface of the exhaust flow path A defined by the second flow path plate 32 can be formed as an inclined surface, where the vertical level varies along the horizontal direction.

[0269] According to the present embodiment, the second suction hole 214 can be arranged to face the first suction hole 112, and the first suction hole 112 is arranged to face the corner fan assembly 200. The vertical height of the first discharge hole 114 can be higher than the vertical height of the first suction hole 112, and can be higher than the vertical height of the second suction hole 214.

[0270] In one example, the second flow path plate 32 can constitute an inclined surface that extends horizontally from the lower side of the second suction hole 214 towards the upper side of the first suction hole 112. For example, the second flow path plate 32 can extend from one end of the second flow path plate adjacent to the corner fan assembly 200 in the horizontal direction and extend horizontally and upwardly inclined towards the rear fan assembly 100.

[0271] One end of the second flow path plate 32 in the horizontal direction can be arranged below the second suction hole 214. For example, the left end of the second flow path plate 32 can be arranged at a vertical height lower than the vertical height of the second suction hole 214.

[0272] In addition, the other end of the second flow path plate 32 in the horizontal direction can be arranged at a position above the first suction hole 112. For example, the vertical height of the right end of the second flow path plate 32 can be higher than the vertical height of the first suction hole 112.

[0273] The second flow path plate 32 can constitute an inclined wall that blocks the first suction hole 112 and the first discharge hole 114 from each other and blocks the first suction hole 112 and the second suction hole 214 from each other. That is to say, the second flow path plate 32 can constitute an inclined wall while being arranged between the rear fan assembly 100 and the corner fan assembly 200, and this wall can not only block the first suction hole 112 and the first discharge hole 114 from each other, but also block the first suction hole 112 and the second suction hole 214 from each other.

[0274] Therefore, between the rear fan assembly 100 and the corner fan assembly 200, the air discharged from the first discharge hole 114 does not flow into the first suction hole 112, and the air discharged through the second suction hole 214 does not flow into the first suction hole 112.

[0275] That is, the second flow path plate 32 can form a wall that blocks air from flowing from the first discharge hole 114 and the second suction hole 214 to the first suction hole 112, such that the wall is located between the rear fan assembly 100 and the corner fan assembly 200.

[0276] According to the present embodiment, the exhaust flow path A can be formed on the left side of the first flow path plate 31 and the upper side of the second flow path plate 32. The air intake hole 1 can be provided below the exhaust flow path A. Additionally, in the vertical direction, the first suction hole 112 and the second suction hole 212 can be provided between the air intake hole 1 and the exhaust flow path A, and the first discharge hole 114 and the second suction hole 214 can be provided between the exhaust flow path A and the upper space 10i.

[0277] The first discharge hole 114 and the second suction hole 214 can be connected to the exhaust flow path A. The first discharge hole 114 can be provided to face upward and connected to the exhaust flow path A. The second suction hole 214 can be provided to face laterally and connected to the exhaust flow path A.

[0278] In addition, the second flow path plate 32 can define a flow path for guiding air to the first suction hole 112.

[0279] In one example, the second flow path plate 32 is provided above the air intake hole 1, and can be provided on the left side and above the first suction hole 112. The second flow path plate 32 can define the left boundary surface and the upper boundary surface of the flow path connecting the air intake hole 1 and the first suction hole 112 to each other. Due to the second flow path plate 32 arranged as above, air can be effectively introduced from the left side of the rear fan assembly 100 into the first suction hole 112.

[0280] In one example, the flow path defining member 30 can further include a fastening plate 33. The fastening plate 33 can be installed at the rear fan assembly 100.

[0281] In one example, the fastening plate 33 can be configured such that the first discharge hole 114 opens upward, and can be coupled to the upper surface of the rear fan assembly 100. The fastening plate 33 can be provided above the first suction hole 112. The vertical height of the fastening plate 33 can be higher than the vertical height of each of the second suction hole 212 and the second suction hole 214.

[0282] According to this embodiment, the first flow path plate 31 may be provided in a form extending upward from the fastening plate 33. Additionally, the second flow path plate 32 may be provided in a form extending downward from the fastening plate 33. That is, the upper end of the second flow path plate 32 may be connected to the fastening plate 33.

[0283] The first flow path plate 31 and the second flow path plate 32 connected to the fastening plate 33 may be coupled to the rear fan assembly 100 via the fastening plate 33.

[0284] Additionally, the fastening plate 33 may be disposed between the first flow path plate 31 and the second flow path plate 32 to connect the first flow path plate 31 and the second flow path plate 32 to each other. In one example, the flow path defining member 30 may be provided in a form in which the first flow path plate 31, the second flow path plate 32, and the fastening plate 33 are integrally formed with each other.

[0285] In the flow path defining member 30 arranged in this way, the first flow path plate 31 and the second flow path plate 32 do not need to be separately coupled to the rear fan assembly 100, and the first flow path plate 31 and the second flow path plate 32 can be easily and quickly installed on the fastening plate 33 coupled to the rear fan assembly 100.

[0286] The fastening plate 33 may have a discharge hole (omitted from the drawing reference numerals) defined therein. The first discharge hole 114 may be exposed to the upper side of the fastening plate 33, that is, the inside of the exhaust flow path A, through this discharge hole.

[0287] Additionally, the cooking appliance of this embodiment may further include a support member 40. The support member 40 is configured to support the corner fan assembly 200. At least a part of the support member 40 may be disposed in the corner spaces 10g and 10h.

[0288] In one example, the support member 40 may include a lateral support 41. The lateral support 41 may be disposed on the lateral side of the corner fan assembly 200. The lateral support 41 may constitute the side surface of the support member 40, more specifically, the right side surface of the support member 40.

[0289] The lateral support 41 is disposed on the lateral side of the corner fan assembly 200 and constitutes a vertical wall covering the corner fan assembly 200. For example, the lateral support 41 may constitute a vertical plane orthogonal to the lateral axis. The lateral support 41 may constitute a wall in the rear space 10a that blocks the corner fan assembly 200 and the rear fan assembly 100 from each other.

[0290] The lateral support 41 may be disposed between the corner fan assembly 200 and the second flow path plate 32. The lateral support 41 may define the left boundary surface of the exhaust flow path A.

[0291] Discharge holes (reference numerals omitted) may be formed in the lateral support member 41. The second suction hole 214 may be exposed to the right side of the lateral support member 41 through the discharge holes, that is, inside the exhaust flow path A.

[0292] In addition, the cooking appliance according to the present embodiment may further include connection flow path defining members 37, 38. The connection flow path defining members 37, 38 may be provided on the upper side of the corner fan assembly 200. The connection flow path defining members 37, 38 may partition the rear space 10f such that a part of the area around the support member 40 in the rear space 10f is separated as the connection flow path 39.

[0293] In one example, the connection flow path defining members 37, 38 may include a first partitioning portion 37 and a second partitioning portion 38.

[0294] The first partitioning portion 37 may constitute a vertical wall provided on the lateral side of the support member 40 and spaced apart from the support member 40 by a predetermined distance. In one example, the first partitioning portion 37 may constitute a vertical wall provided on the lateral side of the lateral support member 41 and spaced apart from the lateral support member 41 by a predetermined distance. In the left lateral upward direction, the first partitioning portion 37 may be provided between the corner fan assembly 200 and the rear fan assembly 100.

[0295] The second partitioning portion 38 may constitute a wall connecting the lateral support member 41 and the first partitioning portion 37 to each other. In one example, the first partitioning portion 37 may be provided on the right side of the lateral support member 41 and at a position spaced apart from the lateral support member 41 by a predetermined distance. The second partitioning portion 38 may constitute a wall connecting the lower end of the first partitioning portion 37 and the lateral support member 41 to each other.

[0296] In one example, the second partitioning portion 38 may be provided above the second flow path plate 32. The left end of the second partitioning portion 38 may be connected to the lateral support member 41. In addition, the left end of the second partitioning portion 38 may be spaced apart from the left end of the second flow path plate 32 in the vertical direction, while the second suction hole 214 is interposed between the left end of the second partitioning portion 38 and the left end of the second flow path plate 32.

[0297] In one example, the second partitioning portion 38 may also constitute an inclined surface parallel to the second flow path plate 32. The second partitioning portion 38 and the lateral support member 41 together may define the left boundary surface of the exhaust flow path A and may guide the air flow discharged from the second suction hole 214 to the lateral center point of the exhaust flow path A.

[0298] The first partition portion 37 may extend upward from the second partition portion 38. Therefore, the first partition portion 37 together with the lateral support member 41 and the second partition portion 38 may define a left boundary of the exhaust flow path A. The first partition portion 37 may also guide the flow of air passing through the exhaust flow path A toward the upper space 10i.

[0299] When the operation of the blowers 100 and 200 is started, as shown in FIG. Figures 8 to 10 and Figure 13 As shown, a suction airflow for sucking air outside the cooking utensil into the cooking utensil can be generated. The suction airflow generated as described above acts on the external air sucked through the air intake hole 1 provided at the lower end of the cooking utensil. The external air (i.e., cooking gas) around the air intake hole 1 can be sucked into the main body 10 through the air intake hole 1 under the suction airflow acting in this manner.

[0300] The cooking gas sucked into the body 10 may be introduced into the rear space 10f in the space defined in the body 10. The cooking gas introduced into the rear space 10f may be sucked into the rear fan assembly 100 and the corner fan assembly 200 through the first suction holes 112 provided at two opposite sides of the rear fan assembly 100 and the suction holes provided at the lower side of the corner fan assembly 200, respectively.

[0301] In this regard, air entering the rear fan assembly 100 may be guided by at least a portion of the flow path defining member 30 . Specifically, air suction to the first suction hole 112 disposed on the left side of the rear fan assembly 100 may be guided by the second flow path plate 32 .

[0302] The air sucked into the rear fan assembly 100 and the corner fan assembly 200 may be discharged through the first discharge hole 114 and the second suction hole 214, respectively. The airflow discharged in this manner may be guided by the exhaust flow path A.

[0303] The air discharged from the second discharge hole 214 of the corner fan assembly 200 may flow through the exhaust flow path A, then flow through the rear space 10i and flow to the upper space 10f. The exhaust flow path A may constitute an inclined flow path around the second discharge hole 214 extending obliquely from the second discharge hole 214 to the upper right.

[0304] The right upward inclined flow path formed as above can reduce the flow resistance in the exhaust flow path A and minimize the airflow loss inside the cooking appliance. The right upward inclined flow path formed as above can be formed on the right side of the second suction hole 214 by the second flow path plate 32 defining the lower boundary surface of the exhaust flow path A and the connecting flow path defining members 37 and 38 defining the left boundary surface of the flow path.

[0305] In addition, the air discharged from the first discharge hole 114 of the rear fan assembly 100 can flow through the exhaust flow path A and through the rear space 10i, and then flow into the upper space 10f. In this regard, the exhaust flow path A can guide the air flow such that the air discharged through the first discharge hole 114 can flow toward the upper space 10i without diffusing to its surroundings.

[0306] [Another example of the flow path defining member]

[0307] Referring to Figure 11 and Figure 12 , the flow path defining member 35 may further include an extension plate 34. The extension plate 34 may form a wall that blocks the first suction hole 112 and the first discharge hole 114 from each other.

[0308] Similar to the second flow path plate 32a, the extension plate 34 may be provided on the left side of the rear fan assembly 100. The extension plate 34 is provided on the upper side of the rear fan assembly 100, and the second flow path plate 32a extends downward from the extension plate 34. In one example, the extension plate 34 may be provided above the second flow path plate 32a and may be provided in a form extending upward from the second flow path plate 32a.

[0309] In the lateral direction, the rear fan assembly 100 may be provided between the extension plate 34 and the first flow path plate 31. In addition, the extension plate 34 may be provided between the rear fan assembly 100 and the corner fan assembly 200 in the lateral direction. In addition, the extension plate 34 may be provided between the lateral support member 41 and the fastening plate 33 in the lateral direction and between the connecting flow path defining member 35 and the fastening plate 33.

[0310] The extension plate 34 arranged as above may be provided between the lateral support member 41 and the first flow path plate 31 and between the connecting flow path defining member 35 and the first flow path plate 31 in the exhaust flow path A. That is, the extension plate 34 may also form a vertical wall between the left and right boundaries of the exhaust flow path A.

[0311] The extension plate 34 may divide the exhaust flow path A into a first exhaust flow path A1 forming its right side and a second exhaust flow path A2 forming its left side. The extension plate 34 may define the left boundary of the first exhaust flow path A1 and may define the right boundary of the second exhaust flow path A2.

[0312] The first exhaust flow path A1 may form a channel connecting the first discharge hole 114 and the upper space 10i to each other such that the channel is defined in the rear space 10f. The second exhaust flow path A2 may form a channel connecting the second suction hole 214 and the upper space 10i to each other such that the channel may be formed in the rear space and the channel is isolated from the first exhaust flow path A1.

[0313] In addition, the flow path defining member 35 may be divided into a first flow path defining member 35a and a second flow path defining member 35b. In one example, the first flow path defining member 35a may be provided in a form in which the first flow path plate 31 and the fastening plate 33 are connected to each other, and the second flow path defining member 35b may be provided in a form in which the second flow path defining member 35b and the extension plate 34 are connected to each other.

[0314] The first flow path defining member 35a may be disposed inside the cooking appliance through the connection of the fan housing of the rear fan assembly 100 and the fastening plate 33. The second flow path defining member 35b may be installed inside the cooking appliance via the connection between the second flow path plate 32a and the lateral support member 41.

[0315] The exhaust flow path A may be divided into a first exhaust flow path A1 and a second exhaust flow path A2 via the flow path defining member 35 as described above. Accordingly, the air discharged to the rear space 10f through the rear fan assembly 100 and the air discharged to the rear space 10f through the corner fan assembly 200 may flow toward the upper space 10i through separate flow paths, respectively.

[0316] The flow path defining member 35 may divide the exhaust flow path A into a first flow path and a second flow path as described above, thereby being able to suppress the mixing of the air discharged from the corner fan assembly 200 and the air discharged from the rear fan assembly 100 within the exhaust flow path A.

[0317] [Structure of air intake and discharge of cooking appliance]

[0318] Figure 14 is a rear perspective view showing a first state of a cooking appliance according to a first embodiment of the present disclosure, and Figure 15 is as shown Figure 14 a view showing an air flow state in the cooking appliance. Figure 16 is a rear perspective view showing a second state of a cooking appliance according to a first embodiment of the present disclosure, and Figure 17 is as shown Figure 16 a view showing an air flow state in the cooking appliance. Figure 18 is a rear perspective view showing a third state of a cooking appliance according to a first embodiment of the present disclosure, and Figure 19 is as shown Figure 18 a view showing an air flow state in the cooking appliance.

[0319] Hereinafter, a structure for sucking and discharging air in a cooking device according to the present embodiment will be described with reference to Figures 13 to 19 the description.

[0320] With reference to Figures 13 to 15, the air intake hole 1 can be provided at the lower end of the cooking appliance, and the exhaust hole can be provided at the upper end of the cooking appliance. The first exhaust hole 2 can be provided in the upper surface of the cabinet 13 and can be provided closer to the rear side of the cooking appliance, and the second exhaust hole 3 can be provided in the upper surface of the cabinet 13 and can be provided closer to the front side of the cooking appliance. Additionally, the third exhaust hole 4 can be provided in the rear end of the cooking appliance and can be defined in the rear plate 15.

[0321] The blower fans 100 and 200 can include a rear fan assembly 100 and a corner fan assembly 200, and the rear fan assembly 100 can be provided in the rear space 10f. The corner fan assembly 200 can be provided in the rear space 10f or the corner spaces 10g and 10h.

[0322] When each of the rear fan assembly 100 and the corner fan assembly 200 starts operating, a suction air flow can be generated for sucking the air outside the cooking appliance into the cooking appliance. The suction air flow generated as described above acts on the outside air through the air intake hole 1 provided at the lower end of the cooking appliance. The outside air (i.e., cooking gas) around the air intake hole 1 can flow through the air intake hole 1 and be sucked into the main body 10 under the suction air flow acting in this way.

[0323] Additionally, the cooking gas sucked into the main body 10 can be introduced into the rear space 10f through the lower space. For example, the cooking gas introduced into the lower space can be introduced into the rear space 10f and the corner spaces 10g and 10h.

[0324] The cooking gas introduced into the rear space 10f can be sucked into the rear fan assembly 100 through the first suction holes 112 provided at two opposite sides of the rear fan assembly 100 respectively. The cooking gas sucked into the rear fan assembly 100 can be discharged upward through the first discharge hole 114 provided at the upper side of the rear fan assembly 100.

[0325] The cooking gas introduced into the corner spaces 10g and 10h can be sucked into the corner fan assembly 200 through the second suction holes 212 provided at the lower surface of the corner fan assembly 200. The cooking gas sucked into the corner fan assembly 200 can be discharged laterally from the corner fan assembly 200 through the second discharge holes 214 provided at the side surface of the corner fan assembly 200.

[0326] The rear space 10f can connect the air intake hole 1 provided below the lower space to the upper space 10i. Additionally, an exhaust air flow path A can be formed in the rear space 10f. The air flow of the cooking gas discharged from the rear fan assembly 100 and the corner fan assembly 200 can be guided toward the upper space 10i through the exhaust air flow path A.

[0327] When only the first exhaust hole 2 among the exhaust holes 2, 3, and 4 is open and the second exhaust hole 3 and the third exhaust hole 4 among the exhaust holes 2, 3, and 4 are closed (hereinafter referred to as "the first state of the cooking appliance"), the cooking gas flowing upward through the exhaust flow path A can be discharged to the outside through the first exhaust hole 2.

[0328] In one example, the first exhaust hole 2 can be connected to a pipe (not shown) communicating with the outdoor area. For example, the pipe can be installed on the upper surface of the main body 10, and the internal space of the pipe can be connected to the first exhaust hole 2.

[0329] The first exhaust hole 2 connected to the pipe as described above can constitute a passage connecting the upper space 10i to the outside of the cooking appliance. The first exhaust hole 2 can be provided above the upper space 10i and can be provided at a position vertically overlapping the rear space 10f.

[0330] That is, the rear fan assembly 100, the rear space 10f, and the first exhaust hole 2 can vertically overlap each other. Preferably, the rear fan assembly 100, the rear space 10f, and the first exhaust hole 2 can be aligned with each other in a line along the vertical direction.

[0331] In addition, the exhaust flow path A can be provided between the blowers 100, 200 and the first exhaust hole 2 and within the rear space 10f. The inlet of the exhaust flow path A can be opened toward the blowers 100, 200, and the outlet of the exhaust flow path A can be opened toward the upper space 10i. In addition, the first exhaust hole 2 can be provided in a region vertically overlapping the outlet of the exhaust flow path A.

[0332] Therefore, the air flow generated by the operation of the rear fan assembly 100 can have a linear direction same as the alignment direction of the rear fan assembly 100, the rear space 10f, and the first exhaust hole 2.

[0333] As described above, when the air flows in a linear direction, the resistance to the air flow is reduced, so that the air flow can proceed more smoothly. Therefore, the air suction and discharge performance of the rear fan assembly 100 can be improved, and accordingly, the cooking gas removal performance of the cooking appliance can be improved.

[0334] In one example, the cooking appliance of the present embodiment can discharge the cooking gas sucked into the cooking appliance into the indoor space, as Figure 16 and Figure 17 shown. In this regard, the cooking appliance can be in a state where only the second exhaust hole 3 among the exhaust holes 2, 3, and 4 is open and its first exhaust hole 2 and third exhaust hole 4 are closed (hereinafter, referred to as "the second state of the cooking appliance").

[0335] In the second state of the cooking appliance, the passage for discharging the cooking gas sucked into the interior of the cooking appliance into the indoor space may consist of the second exhaust hole 3. That is, the cooking gas introduced into the rear space 10f through the air intake hole 1 may flow through the upper space 10i and then be discharged into the indoor space through the second exhaust hole 3.

[0336] In one example, a filter (not shown) may be provided at the bottom surface of the cooking appliance. The filter may be provided in the air intake hole 1, and the cooking gas may flow through the air intake hole 1 while being filtered by the filter.

[0337] In another example, the filter may be provided in the upper space 10i. For example, the filter may be provided inside the main body 10 and may be provided in the second exhaust hole 3. In this case, the cooking gas flowing from the rear space 10f to the upper space 10i may flow through the filter and be discharged into the indoor space through the second exhaust hole 3 in a state where the air has been filtered by the filter.

[0338] As Figure 18 and Figure 19 shown, the cooking appliance of the present embodiment can discharge the cooking gas sucked into the cooking appliance to the outside through the third exhaust hole 4.

[0339] In this regard, the cooking appliance may be in a state where only the third exhaust hole 4 is open and the first exhaust hole 2 and the second exhaust hole 3 among the exhaust holes 2, 3, and 4 are closed (hereinafter referred to as the "third state of the cooking appliance").

[0340] In one example, the third exhaust hole 4 may be connected to a pipe or conduit (not shown) embedded in the wall surface on which the cooking appliance is mounted. For example, the pipe or conduit may be connected to the rear plate 15, and the internal space of the pipe or conduit may be connected to the third exhaust hole 4.

[0341] The third exhaust hole 4 connected to the pipe or conduit is provided at the position closest to the blowers 100, 200. Therefore, in the third state of the cooking appliance, the distances between the blowers 100 and 200 and the exhaust holes 2, 3, and 4 can be the shortest. In addition, since the third exhaust hole 4 is defined in the rear surface of the cooking appliance facing the wall surface, the third exhaust hole 4 and the pipe or conduit are not exposed to the outside.

[0342] That is, when the cooking appliance is in the third state, the cooking appliance can reduce the flow resistance inside the cooking appliance by reducing the air flow distance inside the cooking appliance, and can keep the appearance of the cooking appliance simple and clean.

[0343] As described above, the cooking appliance according to the present embodiment has a structure in which the blowers 100 and 200 are disposed in the rear space 10f, so that the flow of air involved in sucking the cooking gas and discharging the cooking gas through the first exhaust hole 2 proceeds in a straight line direction, thereby minimizing the air flow loss in the cooking appliance and providing more improved cooking gas removal performance.

[0344] In addition, in the cooking appliance according to the present embodiment, a filter installation space can be effectively secured in the upper space 10i, thereby maintaining a compact size and smoothly filtering the cooking gas and discharging the cooking gas into the indoor space.

[0345] In one example, as described above, the space inside the main body 10 can be divided into a side space 10e, a rear space 10f, and an upper space 10i, and the blowers 100 and 200 according to the present embodiment are disposed in the rear space 10f, rather than in the side space 10e or the upper space 10i.

[0346] Generally, the lateral length of the side space 10e where no electronic / electrical component chamber is provided is set to be shorter than the front-rear direction length of the rear space 10f. That is, the side space 10e can only provide a space narrower than the rear space 10f.

[0347] According to the type of the cooking appliance, various devices can be disposed in the rear space 10f. For example, in a cooking appliance providing a convection function, a convection module can be disposed in the rear space 10f.

[0348] On the other hand, it is very rare to dispose devices in the side space 10e that does not constitute the electronic / electrical component chambers 10b, 10c, 10d. Therefore, the lateral width of the lateral space 10e does not need to be increased unnecessarily. When the lateral length of the side space 10e is increased unnecessarily, only the overall size of the cooking appliance increases regardless of whether the performance of the cooking appliance is improved.

[0349] Considering this fact, the side space 10e is formed to provide a space narrower than the rear space 10f.

[0350] To reduce costs, different types of cooking appliances having the same cooking chamber volume generally adopt the same size of the main body 10. For example, the main body 10 having the same size as that adopted by a cooking appliance providing only a high-frequency function can be used to manufacture a cooking appliance providing both a high-frequency function and a convection function.

[0351] Therefore, the main body 10 of the present embodiment can include a rear space 10f that provides a space suitable for accommodating a convection module therein, and the side space 10e can be formed in a form that only provides a space narrower than the rear space 10f.

[0352] In view of this fact, the blowers 100 and 200 of the present embodiment can be provided in the rear space 10f that provides more space than the side space 10e. As described above, the blowers 100 and 200 are provided in the rear space 10f so that the air flow loss inside the cooking appliance can be reduced as described above, and a larger fan assembly with high performance can be applied to the blowers 100 and 200.

[0353] That is, the cooking appliance of the present embodiment including the blowers 100 and 200 provided in the rear space 10f can provide improved cooking gas removal performance while suppressing an increase in the size of the cooking appliance using the main body 10 of a common size.

[0354] [Support member]

[0355] Figure 20 is an enlarged view showing the corner fan assembly and its surroundings in an enlarged manner, Figure 21 shows from Figure 20 is a rear perspective view showing a state in which the support member is removed from the cooking appliance shown. Figure 22 is a rear perspective view showing a part of a cooking appliance applying another example of the support member, and Figure 23 shows from as Figure 22 is a rear perspective view of the support member removed from the cooking appliance shown.

[0356] Referring to Figure 6 , Figure 20 and Figure 21 , the cooking appliance of the present embodiment may include a support member 40. The support member 40 can support the corner fan assembly 200 so that the air flow discharged from the second suction hole 214 can be guided toward the rear space 10f.

[0357] At least a part of the support member 40 can constitute a wall that blocks the side space 10e and the rear space 10f from each other. That is, at least a part of the support member 40 can constitute a wall that blocks the corner fan assembly 200 and the rear fan assembly 100 in the rear space 10f from each other.

[0358] The support member 40 can constitute a wall that divides the rear space 10f into two regions arranged in the lateral direction. In one example, the support member 40 can divide the portion of the rear space 10f adjacent to the side space 10e into corner spaces 10g and 10h. In addition, at least a part of the support member 40 can constitute a wall that covers the corner fan assembly 200 while being provided on the side of the corner fan assembly 200. Such a wall can be constituted by a lateral support 41.

[0359] The second suction hole 214 may be provided at a side portion of the corner fan assembly 200 and may face the support member 40, and more specifically, the lateral support 41. Additionally, a discharge hole 41a may be formed in the lateral support 41. The discharge hole 41a may be configured to laterally expose the second suction hole 214 and may be formed to extend laterally through the lateral support 41.

[0360] The lateral support 41 may be coupled to the corner fan assembly 200. That is, the corner fan assembly 200 may be coupled to the lateral support 41 from the side and may be supported by the support member 40.

[0361] The support member 40 may include a front support 42. The front support 42 constitutes the front surface of the support member 40 and is provided in front of the corner fan assembly 200.

[0362] While being provided in front of the corner fan assembly 200, the front support 42 may constitute a vertical wall covering the corner fan assembly 200. For example, the front support 42 may constitute a vertical plane orthogonal to the front - rear axis. The front support 42 may be provided between the cooling fan 6 (see Figure 25 ) and the corner fan assembly 200 to be described later and may constitute a wall that blocks the cooling fan 6 and the corner fan assembly 200 from each other such that the wall is located in the electronic / electrical component chambers 10b, 10c, and 10d.

[0363] The front support 42 may be connected to the lateral support 41 at a side of the lateral support 41. In one example, the right end of the front support 42 may be connected to the front end of the lateral support 41. For example, the front support 42 and the lateral support 41 may be coupled to each other to form an "L" shape.

[0364] The front support 42 connected to the lateral support 41 may support the lateral support 41 while being provided in front of the lateral support 41. The front support 42 may function as a shielding wall that shields the cooling fan 6 and the corner fan assembly 200 and may function as a support wall that supports the lateral support 41 for supporting the corner fan assembly 200.

[0365] In addition, the front support 42 may include a support surface that constitutes a vertical plane for coupling with electronic / electrical components. For example, electronic / electrical components such as a magnetron, a high - voltage transformer, a high - voltage capacitor, a noise filter, etc. may be provided in the electronic / electrical component chambers 10b, 10c, and 10d, and at least one of the electronic / electrical components may be mounted on the support surface of the front support 42. In this embodiment, a high - voltage capacitor is shown mounted on the support surface of the front support 42.

[0366] In addition, the support member 40 may further include an upper support member 43. The upper support member 43 forms the upper surface of the support member 40 and is disposed on the upper side of the corner fan assembly 200. In one example, the upper support member 43 may be disposed in the corner spaces 10g and 10h.

[0367] The upper support member 43 may be disposed above the lateral support member 41 and the front support member 42 and may be connected to at least one of the lateral support member 41 and the front support member 42 in the vertical direction. In the present embodiment, it is shown that the upper support member 43 is connected to both the lateral support member 41 and the front support member 42.

[0368] On the other hand, the front end of the upper support member 43 may be connected to the upper end of the front support member 42, and the right end of the upper support member 43 may be connected to the upper end of the lateral support member 41. Due to the upper support member 43, the three-direction surfaces of the support member 40 are connected to each other, so that the structural stability of the support member 40 can be improved.

[0369] In addition, the upper support member 43 may include a support surface for forming a horizontal plane for coupling with electronic / electrical components. In the present embodiment, it is shown that a noise filter connected to the corner fan assembly is mounted on the support surface of the upper support member 43.

[0370] The support member 40 including the lateral support member 41, the front support member 42, and the upper support member 43 as described above may provide a shielding wall that blocks the cooling fan 6 and the corner fan assembly 200 from each other, and may also provide a support wall for stably mounting the electronic / electrical components and the corner fan assembly 200.

[0371] In one example, the support member 40 may be provided in a form in which the lateral support member 41, the front support member 42, and the upper support member 43 are integrally formed with each other. The support member 40 can facilitate the assembly and installation of the electronic / electrical components and the management of the components, and can have excellent structural stability.

[0372] As another example, as Figure 22 and Figure 23 shown, the lateral support member, the front support member, and the upper support member may be separately provided.

[0373] Therefore, the support member 45 may include a first support plate 45a, a second support plate 45b, and a third support plate 45c. The first support plate 45a, the second support plate 45b, and the third support plate 45c may be separately provided.

[0374] For example, the first support plate 45a may constitute a lateral support member, the second support plate 45b may constitute a front support member, and the third support plate 45c may constitute an upper support member. The first support plate 45a, the second support plate 45b, and the third support plate 45c, which are provided as separate plates, may be coupled to each other to form a support member 40.

[0375] In one example, the first support plate 45a may be provided in a form including a lateral support member and connection flow path defining members 37 and 38 both. That is, in the first support plate 45a, the lateral support member and the connection flow path defining members 37 and 38 may be integrally formed with each other.

[0376] In addition, through holes 41b may be defined in the first support plate 45a or may be defined in the third support plate 45c.

[0377] [Structure of electronic / electrical component chamber]

[0378] Figure 24 is a view showing a state in which outside air is introduced into the electronic / electrical component chamber through a cold air inlet. Figures 25 to 27 is a view showing a flow state of air introduced into the electronic / electrical component chamber. Figure 28 is a view showing a flow state of air introduced from an upper corner space into a lower corner space through a connection flow path.

[0379] Referring to Figure 24 and Figure 25 , the main body 10 may have a cold air inlet 5 defined therein. The cold air inlet 5 may be provided in the upper surface of the main body 10, in which a first exhaust hole 2 and a second exhaust hole 3 are defined.

[0380] In one example, the cold air inlet 5 may be formed to penetrate the upper surface of the cabinet 13 in a vertical direction. The cold air inlet 5 may be provided above the electronic / electrical component chambers 10b, 10c, and 10d and may lead the electronic / electrical component chambers 10b, 10c, and 10d to the outside of the main body 10. Outside air may be introduced into the electronic / electrical component chambers 10b, 10c, and 10d through the cold air inlet 5.

[0381] Referring to Figures 25 to 26 , the cooking appliance of the present embodiment may include a partition plate 50. The partition plate 50 may be provided in the side space 10e, and more specifically, in the electronic / electrical component chambers 10b, 10c, and 10d.

[0382] In one example, the partition plate 50 can also form a horizontal plane orthogonal to the vertical axis. The partition plate 50 can vertically partition the side space 10e into a lower electronic / electrical component chamber 10b and an upper electronic / electrical component chamber 10c. For example, the electronic / electrical component chambers 10b, 10c, 10d can be divided into a lower electronic / electrical component chamber 10b below the partition plate 50 and an upper electronic / electrical component chamber 10c above the partition plate 50.

[0383] In one example, among the electronic / electrical component chambers 10b, 10c, and 10d, the lower electronic / electrical component chamber 10b can occupy a much wider space than the upper electronic / electrical component chamber 10c. For example, the vertical length of the lower electronic / electrical component chamber 10b can be set to be much greater than the vertical length of the upper electronic / electrical component chamber 10c. Most of the electronic / electrical components including a magnetron, a high-voltage transformer, a high-voltage capacitor, etc. can be mainly arranged in the lower electronic / electrical component chamber 10b.

[0384] The cooking appliance of the present embodiment can further include a cooling fan 6. The cooling fan 6 is configured to be able to introduce external air into the electronic / electrical component chambers 10b, 10c, 10d via the cold air suction hole 5. In one example, the cooling fan 6 together with most of the electronic / electrical components can be arranged in the lower electronic / electrical component chamber 10b.

[0385] The blowers 100 and 200 can be arranged behind the cooling fan 6. The support member 40, more specifically, the front support 42 can be arranged between the cooling fan 6 and the corner fan assembly 200.

[0386] The cooling fan 6 can generate an air flow for introducing external air into the main body 10 through the cold air inlet 5.

[0387] When the cooling fan 6 operates, external air can be introduced into the upper electronic / electrical component chamber 10c through the cold air inlet 5. The air introduced into the upper electronic / electrical component chamber 10c can flow through the partition plate 50 and be introduced into the lower electronic / electrical component chamber 10b.

[0388] For this purpose, the partition plate 50 can have through holes 52 and 54 defined therein. The through holes 52 and 54 can form a passage connecting the upper electronic / electrical component chamber 10a and the lower electronic / electrical component chamber 10b to each other, such that the passage is defined in the partition plate 50. In one example, the through holes 52 and 54 can be formed to extend in the vertical direction through the partition plate 50.

[0389] The air introduced into the upper electronic / electrical component chamber 10c through the cold air inlet 5 can be introduced into the lower electronic / electrical component chamber 10b through the through holes 52 and 54. The air introduced into the electronic / electrical component chambers 10b, 10c, and 10d can cool the electronic / electrical components provided in the lower electronic / electrical component chamber 10b.

[0390] In addition, a part of the air introduced into the lower electronic / electrical component chamber 10b can be introduced into the cooking chamber 10a (see Figure 2 ). To this end, the cavity 11 can have a side hole 11a. The side hole 11a can form a passage connecting at least one of the lower electronic / electrical component chamber 10a and the upper electronic / electrical component chamber 10c to the cooking chamber 10a.

[0391] In the present embodiment, the case where the side hole 11a is provided in the lower electronic / electrical component chamber 10b is shown. In one example, the side hole 11a is formed to extend in the lateral direction through the cavity 11, so that a passage connecting the lower electronic / electrical component chamber 10b and the cooking chamber 10a to each other can be formed in the cavity 11. The side hole 11a can be provided in front of the support member 40.

[0392] The cooking appliance of the present embodiment can further include a baffle 55. The baffle 55 can divide the upper electronic / electrical component chamber 10c in the front-rear direction, so that the front region of the upper electronic / electrical component chamber 10d is separated into an air intake chamber 10d.

[0393] In one example, the baffle 55 can form a vertical wall surface orthogonal to the front-rear axis. The baffle 55 can be provided above the partition plate 50 and can be coupled to the upper surface of the partition plate 50.

[0394] Due to the baffle 55 arranged as above, the region between the front plate 12 of the upper electronic / electrical component chamber 10c and the baffle 55 can be separated as the air intake chamber 10d.

[0395] A plurality of through holes 52 and 54 can be defined in the partition plate 50. In one example, the partition plate 50 can have a first through hole 52 and a second through hole 54. The first through hole 52 and the second through hole 54 can be spaced apart from each other in the front-rear direction, while the baffle 55 is interposed between the first through hole 52 and the second through hole 54.

[0396] The first through hole 52 can form a passage connecting the air intake chamber 10a and the lower electronic / electrical component chamber 10b to each other. The first through hole 52 can be provided in front of the baffle 55 and the cooling fan 6, and can be formed to penetrate the partition plate 50 in the vertical direction.

[0397] The second through-hole 54 may form a passage connecting the upper electronic / electrical component chamber 10c and the lower electronic / electrical component chamber 10b to each other, while the second through-hole 54 is provided behind the air intake chamber 10a. The second through-hole 54 may be provided behind the baffle 55 and the cooling fan 6, and may be formed to penetrate the partition plate 50 in the vertical direction.

[0398] According to this embodiment, the upper support member 43 may be provided behind the partition plate 50. The upper support member 43 may be provided in the corner spaces 10g and 10h, and may vertically divide the corner spaces 10g and 10h into an upper corner space and a lower corner space. The corner spaces 10g and 10h may be divided into the upper corner space 10g and the lower corner space 10h via the upper support member 43.

[0399] The lower corner space 10h may be provided below the upper support member 43. The upper boundary surface of the lower corner space 10h may be defined by the upper support member 43, the front boundary surface of the lower corner space 10h may be defined by the front support member 42, and the right boundary surface of the lower corner space 10h may be defined by the lateral support member 41. The corner fan assembly 200 may be provided in the lower corner space 10h.

[0400] The upper corner space 10g may be provided above the upper support member 43. The upper corner space 10g may be provided behind the upper electronic / electrical component chamber 10c, and may communicate with the upper electronic / electrical component chamber 10c while being located behind the upper electronic / electrical component chamber 10c.

[0401] At least one of the electronic / electrical components provided in the upper electronic / electrical component chamber 10c may be provided in the upper support member 43. In one example, a noise filter connected to the corner fan assembly 200 may be provided in the upper corner space 10g, and the noise filter may be mounted on the upper surface of the upper support member 43.

[0402] The air introduced into the lower electronic / electrical component chamber 10b by the cooling fan 6 may flow into the upper electronic / electrical component chamber 10c through the second through-hole 54. Thus, the air introduced into the upper electronic / electrical component chamber 10c may cool the electronic / electrical components provided in the upper support member 43 while flowing through the upper corner space 10g.

[0403] In one example, the upper electronic / electrical component chamber 10c and the lower electronic / electrical component chamber 10b can be connected to each other via a connecting flow path 39. The connecting flow path 39 can form a passage through which the air introduced into the lower electronic / electrical component chamber 10b by the cooling fan 6 flows through the upper electronic / electrical component chamber 10c to the blowers 100 and 200. For example, the connecting flow path 39 can form a path through which the air introduced into the electronic / electrical component chambers 10b, 10c, and 10d can be introduced into the corner fan assembly 200 through the upper corner space 10g.

[0404] In addition, a through hole 41b can be defined in the lateral support 41. The through hole 41b is configured to open the space surrounded by the lateral support 41 and the front support 42, that is, the lower corner space 10h, laterally.

[0405] The connecting flow path 39 can form a passage connecting the through hole 41b and the upper electronic / electrical component chamber 10c to each other, and more specifically, a passage connecting the through hole 41b and the upper corner space 10g to each other. The connecting flow path 39 can also communicate with the upper corner space 10g and the lower corner space 10h in a state of being disposed on the lateral sides of the corner spaces 10g and 10h. The connecting flow path 39 and the lower corner space 10h can communicate with each other through the through hole 41b.

[0406] As described above, the connecting flow path 39 can be defined by the connecting flow path defining members 37 and 38. In the connecting flow path defining members 37 and 38, the first partition portion 37 can form a vertical wall disposed on the lateral side of the lateral support 41 and spaced apart from the lateral support 41 by a predetermined distance. The second partition portion 38 can be connected to the lateral support 41 while being disposed below the through hole 41b, and form a wall connecting the lateral support 41 and the first partition portion 37 to each other.

[0407] Two opposite side surfaces of the connecting flow path 39 can be defined by the lateral support 41 and the first partition portion 37. For example, the left side surface of the connecting flow path 39 can be defined by the lateral support 41, and the right side surface of the connecting flow path 39 can be defined by the first partition portion 37. The bottom surface of the connecting flow path 39 can be defined by the second partition portion 38.

[0408] The air introduced into the upper electronic / electrical component chamber 10c can flow through the upper corner space 10g and be introduced into the connecting flow path 39. The air flowing into the connecting flow path 39 can flow into the lower corner space 10h through the through hole 41b and then be sucked into the corner fan assembly 200.

[0409] The suction force of the corner fan assembly 200 can act on the lower corner space 10h. As described above, the suction force acting on the lower corner space 10h may also affect the connection flow path 39 connecting the lower corner space 10h and the upper corner space 10g. That is, the suction force of the corner fan assembly 200 can affect the upper corner space 10g, which can be used as a force to make the air flowing into the upper corner space 10g flow toward the lower corner space 10h.

[0410] Finally, the suction force of the corner fan assembly 200 can be used as a force to guide the air flow introduced into the upper electronic / electrical component chamber 10c from the lower electronic / electrical component chamber 10b through the connection flow path 39 to the lower corner space 10h.

[0411] Hereinafter, the air flow in the electronic / electrical component chambers 10b, 10c, and 10d will be described.

[0412] As Figure 24 shown, the outside air can be introduced into the main body 10 through the cold air inlet 5. The air that has flowed through the cold air inlet 5 can be introduced into the air intake chamber 10d, as Figures 25 to 27 shown.

[0413] The air introduced into the air intake chamber 10d can flow through the first through hole 52 across the partition 50 and can flow into the lower electronic / electrical component chamber 10b. In the lower electronic / electrical component chamber 10b, the air can flow in the backward direction through the cooling fan 6. As described above, the air flowing backward in the lower electronic / electrical component chamber 10b can cool the electronic / electrical components provided in the lower electronic / electrical component chamber 10b.

[0414] A part of the air flowing in the lower electronic / electrical component chamber 10b can flow through the air intake hole 1 across the cavity 11 and be introduced into the electronic / electrical component chamber. Another part of the air flowing in the lower electronic / electrical component chamber 10b can flow through the second through hole 54 across the partition 50 and flow to the upper electronic / electrical component chamber 10c.

[0415] In the upper electronic / electrical component chamber 10c, the air can flow toward the connection flow path 39 under the influence of the suction force of the corner fan assembly 200. For example, as Figure 28 shown, the air introduced into the upper electronic / electrical component chamber 10c can cool the electronic / electrical components while flowing through the upper corner space 10g, and then flow into the connection flow path 39.

[0416] The air flowing into the connection flow path 39 can flow into the lower corner space 10h through the through hole 41b formed in the lateral support 41 and be sucked into the corner fan assembly 200. That is, as Figure 13As shown, the air flowing into the lower corner 10h from the connecting flow path 39 merges with the air flowing into the interior of the main body 10 through the air intake holes 1. After merging, the air is sucked into the interior of the corner fan assembly 200 and discharged into the exhaust flow path A.

[0417] As Figures 24 to 28 shown, the flow paths formed in the electronic / electrical component chambers 10b, 10c, and 10d, the corner spaces 10g and 10h, and the connecting flow path 39 allow the force provided by the suction of the corner fan assembly 200 to be added to the force provided by the cooling fans 6 in the electronic / electrical component chambers 10b, 10c, and 10d, thereby allowing air to flow more smoothly within the electronic / electrical component chambers 10b, 10c, and 10d, and thus allowing the electronic / electrical components provided in the electronic / electrical component chambers 10b, 10c, and 10d to be cooled more effectively.

[0418] In addition, the flow paths formed in the electronic / electrical component chambers 10b, 10c, and 10d, the corner spaces 10g and 10h, and the connecting flow path 39 as described above can allow the air introduced into the electronic / electrical component chambers 10b, 10c, and 10d to flow toward the corner fan assembly 200, thereby increasing the air suction volume of the corner fan assembly 200 and ultimately contributing to effectively increasing the discharged air volume of the corner fan assembly 200.

[0419] In one example, referring to Figures 25 to 27 , the cooking appliance of the present embodiment may further include a flow path partition plate 16. The flow path partition plate 16 is configured to partition the cavity 11 and the space above the partition plate 50. The flow path partition plate 16 can partition the cavity 11 and the space above the partition plate 50 into an upper electronic / electrical component chamber 10c and an upper space 10i.

[0420] In one example, the flow path partition plate 16 may also form a vertical wall orthogonal to the horizontal axis. The flow path partition plate 16 can block the upper electronic / electrical component chamber 10c and the upper space 10i from each other and can isolate these two spaces from each other. For example, the flow path partition plate 16 can define the right boundary surface of the upper electronic / electrical component chamber 10c and the left boundary surface of the upper space 10i.

[0421] In addition, the cooking appliance of the present embodiment may include a waveguide 17. The waveguide 17 is configured to transmit microwaves generated from the magnetrons installed in the electronic / electrical component chambers 10b, 10c, and 10d to the cooking chamber 10a.

[0422] The waveguide 17 may be disposed in the upper electronic / electrical component chamber 10c and the upper space 10i, and may be mounted on the upper surface of each of the partition plate 50 and the cavity 11. That is, a part of the waveguide 17 may be mounted on the upper surface of the partition plate 50, and the remaining part of the waveguide 17 may extend in the lateral direction through the flow path partition plate 16 and be mounted on the upper surface of the cavity 11.

[0423] A space is formed inside the waveguide 17, and an inlet of the waveguide 17 connected to the space may be connected to the magnetron, and an outlet of the waveguide 17 connected to the space may be connected to the cooking chamber 10a. The microwave introduced into the waveguide 17 through the inlet of the waveguide 17 may be introduced into the cooking chamber 10a through the outlet of the waveguide 17.

[0424] The outlet of the waveguide 17 may be connected to the cooking chamber 10a while being defined at the upper surface of the cavity 11. Accordingly, the microwave transmitted through the waveguide 17 from the magnetron may flow over the upper surface of the cavity 11 defining the cooking chamber 10a and be introduced into the cooking chamber 10a. In one example, the outlet of the waveguide 17 may be defined in the upper surface of the cavity 11 and may be disposed substantially at the lateral center of the cavity 11.

[0425] When the vertical length of the cooking appliance is shortened, the vertical length of the cooking chamber 10a is likely to be shortened. Even if the blowers 100 and 200 are disposed in the rear space 10f instead of the upper space 10i, and thus the vertical length of the upper space 10i can be correspondingly reduced, the reduction in the length of the upper space 10i is inevitably less than the reduction in the total length of the cooking appliance. Accordingly, it is difficult to avoid the reduction in the length of the cooking chamber 10a due to the reduction in the length of the cooking appliance.

[0426] In this case, compared with the cooking chamber of a typical cooking appliance, the shape of the cooking chamber 10a has a flat shape elongated in the horizontal direction. In a cooking appliance having a cooking chamber 10a with such a shape, when the microwave is introduced into the cooking chamber 10a through the side surface of the cavity 11, it is difficult to supply the microwave uniformly to the entire cooking chamber 10a.

[0427] In view of this situation, in the present embodiment, the waveguide 17 is mounted on the upper surface of the cavity 11, and the microwave may be introduced into the cooking chamber 10a through the upper surface of the cavity 11. That is, in the cooking appliance of the present embodiment, the microwave may be supplied through the upper surface of the cooking chamber 10a, and thus, the microwave may be uniformly supplied to the entire cooking chamber 10a.

[0428] [An example of the shielding member]

[0429] Refer to Figures 25 to 27, the cooking appliance of the present embodiment may include a shielding member 60. The shielding member 60 is configured to shield the through holes 52 and 54 formed in the partition plate 50. More specifically, the first through hole 52 is shielded while being disposed above or below the partition plate 50. The shielding member 60 may be disposed at a predetermined distance from the partition plate 50 or the first through hole 52 in the vertical direction.

[0430] In the present embodiment, the shielding member 60 is shown as being disposed above the partition plate 50 and the first through hole 52. The shielding member 60 may be disposed between the upper surface of the cabinet 13 and the partition plate 50. In one example, the shielding member 60 may be disposed in the upper electronic / electrical component chamber 10c, and more specifically, in the air intake chamber 10d.

[0431] In the vertical direction, the shielding member 60 may be disposed between the first through hole 52 and the cold air inlet 5. The shielding member 60 may be configured such that in a top view of the main body 10, one of the first through hole 52 and the cold air inlet 5 is completely shielded by the shielding member 60.

[0432] In one example, the shielding member 60 may be configured such that the first through hole 52 is completely shielded by the shielding member 60. For example, the shielding member 60 may form a horizontal wall that completely shields the first through hole 52 while being located on top of the first through hole 52.

[0433] The shielding member 60 may be mounted on the baffle 55. The shielding member 60 may be mounted on the baffle 55 to be coupled to the front surface of the baffle 55 and project forward from the baffle 55. In this regard, the shielding member 60 may be coupled to the baffle 55 and be at a position spaced a predetermined distance upward from the upper surface of the partition plate 50.

[0434] Due to the shielding member 60, the first through hole 52 is completely shielded, so that an observer above the cooking appliance cannot see the first through hole 52, while the air flow through the first through hole 52 can be smoothly performed. That is, the shielding member 60 shields the first through hole 52 such that the first through hole 52 is not visible from a position above the shielding member 60, while the air in the air intake chamber 10d can be smoothly introduced into the lower electronic / electrical component chamber 10b through the first through hole 52 regardless of the presence of the shielding member 60.

[0435] The shielding member 60 may block the first through hole 52 and the cold air inlet 5 from each other. The shielding member 60 may be used to shield the flame rising from the first through hole 52 while being located between the first through hole 52 and the cold air inlet 5, so that the flame generated in the lower electronic / electrical component chamber 10b does not expose to the outside of the cooking appliance through the cold air inlet 5.

[0436] Most high-voltage electronic / electrical components such as high-voltage transformers and high-voltage capacitors are provided in the lower electronic / electrical component chamber 10b. As described above, the high-voltage electronic / electrical components provided in the lower electronic / electrical component chamber 10b on the lower side have a risk of catching fire in the lower electronic / electrical component chamber 10b.

[0437] When a fire occurs in the lower electronic / electrical component chamber 10b, the generated flames are exposed to the outside of the cooking appliance. Therefore, the flames exposed to the outside of the cooking appliance are transferred to the surrounding environment around the cooking appliance, thereby increasing the risk of fire spread.

[0438] In the cooking appliance, the first through hole 52 is provided on the upper side of the lower electronic / electrical component chamber 10b to form a passage required for the air in the air intake chamber 10d to flow into the lower electronic / electrical component chamber 10b. In addition, the cold air inlet 5 that forms a passage required for introducing external air into the air intake chamber 10d is provided above the first through hole 52.

[0439] Therefore, the flames generated in the lower electronic / electrical component chamber 10b can rise upward through the first through hole 52 into the air intake hole 1, and can rise upward through the cold air inlet 5 in the air intake chamber 10d to the upper side of the main body 10, and be exposed to the outside of the cooking appliance. To prevent this, it is necessary to block the flames generated in the lower electronic / electrical component chamber 10b inside the cooking appliance to prevent the flames from being exposed to the outside of the cooking appliance.

[0440] Taking this into account, in the present embodiment, the shielding member 60 provided in the air intake chamber 10d is configured to be able to block the first through hole 52 and the cold air suction hole 5 from each other. The shielding member 60 can allow the flames generated in the lower electronic / electrical component chamber 10b to be blocked in the air intake chamber 10d, so that the flames generated in the lower electronic / electrical component chamber 10b can be prevented from being exposed to the outside of the cooking appliance.

[0441] The cooking appliance of the present embodiment including the shielding member 60 as described above can smoothly introduce air into the lower electronic / electrical component chamber 10b while significantly reducing the risk of fire spread due to the flames generated inside the cooking appliance.

[0442] [Another example of the shielding member]

[0443] Figure 29 is a rear perspective view showing a part of a cooking appliance to which another example of the shielding member is applied.

[0444] As Figure 29 shown, the baffle 60 (see Figure 27) is not provided in the upper electronic / electrical component chamber 10c. Therefore, the upper electronic / electrical component chamber 10c may not be partitioned in the front-rear direction. The shielding member 65 provided in the upper electronic / electrical component chamber 10c may be provided in a form in which the shielding member 65 is directly mounted on the partition plate 50. In one example, the shielding member 65 may be formed in a hexahedral shape including a horizontal surface portion 66 and a vertical surface portion 67.

[0445] The horizontal surface portion 66 constitutes the upper surface of the shielding member 65 and is configured to shield the first through hole 52 when located at the top of the first through hole 52. In one example, the horizontal surface portion 66 may also constitute a horizontal plane orthogonal to the vertical axis US.

[0446] The shielding member 65 may further include a vertical surface portion 67. The vertical surface portion 67 may constitute a side surface of the shielding member 65 and may be provided between the horizontal surface portion 66 and the partition plate 50. The vertical surface portion 67 may be coupled to the upper surface of the partition plate 50 while spacing the horizontal surface portion 66 from the upper surface of the partition plate 50.

[0447] The shielding member 65 may include a plurality of vertical surface portions 67 surrounding the first through hole 52. A space surrounding the first through hole 52 may be formed inside the shielding member 65 including the plurality of vertical surface portions 67.

[0448] Ventilation holes 67a may be defined in at least one of the plurality of vertical surface portions 67. In the present embodiment, the ventilation holes 67a are shown to be defined in each of the vertical surface portions 67, respectively.

[0449] The ventilation holes 67a may be formed to extend horizontally through the vertical surface portion 67. The ventilation holes 67a may constitute a passage that communicates the outside of the shielding member 65 with the internal space of the shielding member 65. The air introduced into the upper electronic / electrical component chamber 10c through the cold air inlet 5 (see Figure 24 ) may be introduced into the shielding member 65 from the outside of the shielding member 65 through the ventilation holes 67a and then may be introduced into the lower electronic / electrical component chamber 10b through the first through hole 52.

[0450] The shielding member 65 arranged as described above may provide an effect of significantly reducing the risk of fire spread due to a flame generated inside the cooking appliance, and may be effectively installed in the upper electronic / electrical component chamber 10c even without installing the baffle 55.

[0451] [Structure of the upper space]

[0452] Figure 30is a rear perspective view showing the intake state and the exhaust state of the cooking appliance according to the first embodiment of the present disclosure, and Figure 31 is a rear perspective view showing Figure 30 the air flow state inside the cooking appliance as shown Figure 32 is as shown Figure 30 an enlarged plan view of the periphery around the common exhaust hole, Figure 33 is an enlarged view of the exhaust duct and its periphery.

[0453] Referring to Figure 14 , Figure 30 and Figure 32 , the circulating air discharge hole 11b (see Figure 34 ) may be provided inside the main body 10. The circulating air discharge hole 11b may constitute a passage connecting the cooking chamber 10a and the upper space 10i to each other, such that the passage is defined in the upper surface of the cavity 11. In one example, the circulating air discharge hole 11b may be formed to extend vertically through the upper surface of the cavity 11.

[0454] According to the present embodiment, a plurality of second exhaust holes 3 may be provided in the upper surface of the main body 10. At least one of the plurality of second exhaust holes 3 may be provided as a common exhaust hole 3a. The common exhaust hole 3a discharges both the air flowing into the upper space 10i by the blowers 100 and 200 and the air flowing into the upper space 10i from the circulating air discharge hole 11b.

[0455] In one example, the circulating air discharge hole 11b may be provided at a position closer to the right end around the lateral center of the cavity 11. For example, the circulating air discharge hole 11b may be provided at a position overlapping at least a part of the common exhaust hole 3a in the front-rear direction.

[0456] According to the present embodiment, the plurality of second exhaust holes 3 and the cold air inlet 5 may be provided in the lateral direction. In one example, at least one of the plurality of second exhaust holes provided at the position farthest from the cold air inlet 5 may be provided as the common exhaust hole 3a. For example, the cold air inlet 5 may be provided on the left side of the second exhaust holes 3, and one of the second exhaust holes provided on the rightmost side among the plurality of second exhaust holes 3 may be provided as the common exhaust hole 3a.

[0457] In another example, at least one of the plurality of second exhaust holes provided at the position farthest from the electronic / electrical component chambers 10b, 10c, 10d in the lateral direction may be provided as the common exhaust hole 3a.

[0458] In yet another example, at least one of the plurality of second exhaust holes 3 that are arranged horizontally and are disposed at a position closest to the extension plate 18 may be provided as a common exhaust hole 3a. In this regard, at least a portion of the common exhaust hole 3a may be provided to overlap the extension plate 18 in the vertical direction.

[0459] In addition, an exhaust duct 70 may be provided in the upper space 10i. The exhaust duct 70 is configured to direct an air flow discharged from the cooking chamber 10a to the circulation air discharge hole 11b toward the common exhaust hole 3a.

[0460] In the present embodiment, the circulation air discharge hole 11b may be provided at a position closer to the rear side around the front-rear direction center of the cavity 11. For example, the circulation air discharge hole 11b may be provided in the upper surface of the cavity 11 and may be provided at a position adjacent to the right rear corner of the cavity 11.

[0461] The exhaust duct 70 is configured to direct an air flow discharged to the circulation air discharge hole 11b provided at the above-defined position toward the common exhaust hole 3a provided at a position adjacent to the front surface of the main body 10.

[0462] In addition, the cooking appliance of the present embodiment may include an extension plate 18. The extension plate 18 may partition the side space 10e such that a partial area of the side space 10e is separated into an extended upper space 10j. Due to the extension plate 18, the area of the side space 10e above the extension plate 18 may be separated into the extended upper space 10j.

[0463] [Extension plate]

[0464] Referring to Figure 14 、 Figure 30 and Figure 33 , at least a portion of the extension plate 18 may be provided in the side space 10e. In the present embodiment, the extension plate 18 is shown to be provided in the side space 10e of a pair of side spaces 10e provided inside the cooking appliance, rather than in the electronic / electrical component chambers 10b, 10c, and 10d.

[0465] In one example, the extension plate 18 may form a horizontal plane orthogonal to the vertical axis. For example, the extension plate 18 may form a plane parallel to the upper surface of the cavity 11.

[0466] Preferably, the upper surface of the extension plate 18 and the upper surface of the cavity 11 may form the same plane. The upper surface of the cavity 11 may define the bottom surface of the upper space 10i, and the upper surface of the extension plate 18 may define the bottom surface of the extended upper space 10j. Therefore, the bottom surface of the upper space 10i and the bottom surface of the extended upper space 10j may be coplanar with each other.

[0467] The extended upper space 10j arranged as above can communicate with the upper space 10i while being located above the side space 10e. That is, the extended upper space 10j can be arranged above the side space 10e and on the lateral side of the upper space 10i, and can be connected to the upper space 10i in the lateral direction.

[0468] According to this embodiment, the upper space 10i and the extended upper space 10j are connected to each other while being arranged above the cavity 11. Therefore, the exhaust spaces 10i and 10j can be formed above the cavity 11 and the side space 10e. In this embodiment, the exhaust spaces 10i and 10j can be defined as a single space, and the upper space 10i and the extended upper space 10j are connected to each other into this single space while being arranged above the cavity 11 and the extension plate 18.

[0469] The exhaust spaces 10i and 10j formed above the cavity 11 and the extension plate 18 can communicate with the exhaust holes 2, 3, and 4 provided in the upper surface of the main body 10. The exhaust holes 2, 3, and 4 can connect the single space (i.e., the exhaust spaces 10i and 10j) to which the upper space 10i and the extended upper space 10j are connected to each other to the outside of the main body 10.

[0470] The side space 10e and the rear space 10f can communicate with the lower space. The side space 10e and the rear space 10f can be connected to the lower space in the vertical direction, or can be connected to the lower space in the lateral direction. The air intake hole 1 can communicate with the lower space, and the side space 10e and the rear space 10f can communicate with the air intake hole 1 through the lower space.

[0471] A part of the extension plate 18 can be arranged in the rear space 10f. Therefore, a part 18a of the extension plate 18 (hereinafter referred to as the "lateral partition part of the extension plate") can be arranged in the side space 10e, and another part 18b of the extension plate 18 (hereinafter referred to as the "rear partition part of the extension plate") can be arranged in the rear space 10f.

[0472] As described above, the lateral partition part 18a of the extension plate 18 can partition the side space 10e such that a part of the area of the side space 10e is separated into the extended upper space 10j. In addition, the rear partition part 18b of the extension plate 18 can also partition the rear space 10f such that a part of the area of the rear space 10f is separated into the extended upper space 10j.

[0473] That is to say, the extension plate 18 can divide the rear space 10j and the side space 10f such that a part of the area of each of the side space 10f and the rear space 10e is separated into the extended upper space 10a.

[0474] The extension plate 18 may include a first coupling portion 18c. The first coupling portion 18c may be configured for coupling between the extension plate 18 and the cavity 11. In one example, the first coupling portion 18c may be formed to protrude from at least one of the side partition portion 18a and the rear partition portion 18b in the horizontal direction. The first coupling portion 18c may be coupled to the cavity 11 while contacting the upper surface of the cavity 11 in the vertical direction.

[0475] The coupling between the first coupling portion 18c and the cavity 11 may be performed by a joining method such as welding or by a fastening method such as using screws.

[0476] In the present embodiment, it is shown that the first coupling portion 18c protrudes from the side partition portion 18a in the lateral direction. In another example, the first coupling portion 18c may be formed to protrude from the rear partition portion 18b in the forward direction. In yet another example, the first coupling portion 18c may protrude vertically from at least one of the side partition portion 18a and the rear partition portion 18b and be coupled to the side surface of the cavity 11.

[0477] In addition, the extension plate 18 may include at least one of a second coupling portion 18d and a third coupling portion 18e. The second coupling portion 18d and the third coupling portion 18e may be configured for coupling between the extension plate 18 and the cabinet 13.

[0478] The second coupling portion 18d may be formed to protrude from the side partition portion 18a or the first coupling portion 18c. In the present embodiment, it is shown that the first coupling portion 18c protrudes from the side partition portion 18a in the horizontal direction, and the second coupling portion 18d protrudes from the first coupling portion 18c in the vertical direction.

[0479] In one example, the second coupling portion 18d may form a vertical wall orthogonal to the lateral axis. A flat portion parallel to the upper surface of the cabinet 13 may be formed at the upper end of the second coupling portion 18d.

[0480] The third coupling portion 18e may be formed to protrude from the rear partition portion 18b. In one example, the third coupling portion 18e may form a vertical wall orthogonal to the front-rear axis. A flat portion parallel to the upper surface of the cabinet 13 may be formed at the upper end of the third coupling portion 18e.

[0481] The vertical lengths of the second coupling portion 18d and the third coupling portion may be set to lengths corresponding to the distance between the extension plate 18 and the cabinet 13. The second coupling portion 18d and the third coupling portion 18e formed as described above may be coupled to the cabinet 13 while being positioned below the cabinet 13.

[0482] The extension plate 18 can support the cabinet 13 via the connection between the second connection part 18d and the cabinet 13 and the connection between the third connection part 18e and the cabinet 13, so that the upper surface of the cabinet 13 does not sag downward. In addition, the extension plate 18 can be connected to various structures at various positions using the first connection part 18c, the second connection part 18d, and the third connection part 18e, and can thus be stably fixedly installed inside the cooking appliance.

[0483] As an example, the second connection part 18d can be provided between the upper space 10i and the extended upper space 10j. That is, the second connection part 18d can be provided in the exhaust spaces 10i and 10j in the form of a vertical wall that laterally and partially blocks the upper space 10i and the extended upper space 10j from each other.

[0484] The second connection part 18d can have a plurality of ventilation holes defined therein. Each ventilation hole can be formed to extend through the second connection part 18d in the lateral direction, and the ventilation holes can be provided in most areas of the second connection part 18d.

[0485] As described above, the second connection part 18d having a plurality of ventilation holes defined therein can be used as a structure for connection between the extension plate 18 and the cabinet 13 while minimizing the interference with the air flow in the exhaust spaces 10i and 10j caused by the second connection part 18d.

[0486] In the present embodiment, the third connection part 18e is shown to be provided in an area where the rear space 10f and the upper space 10i overlap each other or in an area very close thereto. The third connection part 18e can be provided at a position adjacent to the rear fan assembly 100 provided in the rear space 10f.

[0487] Electronic / electrical components related to the rear fan assembly 100 (for example, electronic / electrical components such as capacitors connected to the rear fan assembly 100) can be connected to the third connection part 18e provided as above. That is, the third connection part 18e can provide a structure for connection between the extension plate 18 and the cabinet 13, and provide a structure for mounting electronic / electrical components related to the rear fan assembly 100.

[0488] [Exhaust Duct]

[0489] Figure 34 is a side sectional view showing the exhaust duct, Figure 35 is a plan view showing a state where the duct bracket is mounted on the upper surface of the cavity, Figure 36 is a view showing a state where the exhaust duct is mounted on the duct bracket.

[0490] Refer toFigures 33 to 35 The exhaust duct 70 may have a flow path defined therein, and the flow path is connected to the circulating air discharge hole 11a. In one example, the exhaust duct 70 may be formed in a polyhedron shape that has a length much larger than each of its lateral length and vertical length in the front-back direction.

[0491] The rear end of the exhaust duct 70 may be disposed between the rear surface of the cavity 11 and the circulating air discharge hole 11b. The front end of the exhaust duct 70 may be disposed between the center of the cavity 11 in the front-back direction and the front surface of the cavity 11.

[0492] For example, the rear end of the exhaust duct 70 may be disposed at a position very close to the rear surface of the cavity 11, and the front end of the exhaust duct 70 may be disposed at a position very close to the front surface of the cavity 11.

[0493] A space is formed inside the exhaust duct 70, and the space may constitute a flow path 70a that is connected to the circulating air discharge hole 11b and defined inside the exhaust duct 70. A duct inlet 70b and a duct outlet 70c may be defined in the exhaust duct 70.

[0494] The duct inlet 70b is configured to open the flow path 70a toward the circulating air discharge hole 11b in a state of being disposed on one side in the length direction of the flow path 70a. The duct outlet 70c is configured to open the flow path inside the exhaust duct 70 toward the common exhaust hole 3a.

[0495] In one example, the duct inlet 70b may be formed in a form in which the bottom surface of the exhaust duct 70 is open. At least a part of the duct inlet 70b may overlap with the circulating air discharge hole 11b in the vertical direction.

[0496] In addition, the duct outlet 70c may be formed in a form in which a part of the upper surface of the exhaust duct 70 is open. The duct outlet 70c may be disposed at a position closer to the front end around the center of the exhaust duct 70 in the front-back direction. The duct outlet 70c may be disposed adjacent to the common exhaust hole 3a.

[0497] In the lateral direction, the duct outlet 70c may be disposed at a position close to the common exhaust hole 3a among the plurality of exhaust holes 2, 3, and 4 disposed in the lateral direction. The duct outlet 70c may be disposed to overlap at least a part of the common exhaust hole 3a in the vertical direction.

[0498] The cooking appliance of the present embodiment may further include a humidity sensor 7. The humidity sensor 7 is installed in the exhaust duct 70 and is configured to measure the humidity inside the flow path 70a.

[0499] The humidity sensor 7 is configured to measure the humidity of the air introduced into the flow path 70b through the circulation air discharge hole 11a in the cooking chamber. In order to effectively measure the humidity of the air introduced into the flow path 70a by the humidity sensor 7, a flow path 70a with a sufficient length is required.

[0500] For this purpose, the circulation air discharge hole 11b can be provided at a position closer to the rear end of the upper space 10i, the duct outlet 70c can be provided at a position closer to the front end of the upper space 10i, and the exhaust duct 70 can be formed to have a sufficient length to cover them.

[0501] The exhaust duct 70 of the present embodiment can be provided between the upper surface of the cavity 11 and the upper surface of the cabinet 13 in the vertical direction. The exhaust duct 70 can include a vertical length change section 71.

[0502] The vertical length change section 71 is a section where the vertical length of the exhaust duct 70 changes along the length direction of the flow path 70a. For example, the vertical length change section 71 can be a section where the vertical length of the exhaust duct 70 changes in the front-rear direction.

[0503] According to the present embodiment, the circulation air discharge hole 11b defined in the cavity 11 is provided at a vertical height lower than the vertical height of the second exhaust hole 3 defined in the upper surface of the cabinet 13. In the vertical length change section 71, the vertical length of the exhaust duct 70 can also decrease as the exhaust duct 70 faces one side (for example, the rear side) in the length direction of the flow path 70a.

[0504] That is to say, in the vertical length change section 71, the upper surface of the exhaust duct 70 can form an inclined surface, and the vertical height of the inclined surface decreases as the exhaust duct 70 extends toward one side in the longitudinal direction of the flow path 70a.

[0505] In other words, in the vertical length change section 71, the vertical length of the exhaust duct 70 can also increase as the exhaust duct 70 faces the other side (for example, the front side) in the length direction of the flow path 70a.

[0506] In the vertical length change section 71, a channel space 10k can be defined between the upper surface of the exhaust duct 70 and the upper surface of the cabinet 13. The channel space 10k can form a channel connecting the space on one side in the lateral direction of the exhaust duct 70 in the upper space 10i and the space on the other side in the lateral direction of the exhaust duct 70 in the upper space 10i, so that the channel is located above the exhaust duct 70. In the present embodiment, the channel space 10k can be formed in such a form that the vertical dimension of the channel space 10k increases as the channel space 10k extends toward the rear side.

[0507] In one example, the cooking appliance of the present embodiment may further include a duct bracket 75. The duct bracket 75 may be configured for connection between the exhaust duct 70 and the cavity 11. The duct bracket 75 may be connected to the upper surface of the cavity 11. Additionally, the exhaust duct 70 may be detachably connected to the duct bracket 75.

[0508] In one example, the duct bracket 75 may include a bracket body 76 and a flange 77.

[0509] The bracket body 76 is a part of the duct bracket 75 and is configured for connection between the duct bracket 75 and the exhaust duct 70. The bracket body 76 may be connected to the upper surface of the cavity 11 and to the exhaust duct 70.

[0510] The flange 77 is a part of the duct bracket 75 and is configured for connection between the duct bracket 75 and the cavity 11. The flange 77 engages with the upper surface of the cavity 11 to connect the bracket body 76 to the upper surface of the cavity 11.

[0511] The flange 77 may form a plane parallel to the upper surface of the cavity 11 and may be configured to contact the upper surface of the cavity 11 in the vertical direction. The connection between the flange 77 and the cavity 11 may be performed by a joining method such as welding.

[0512] Refer to Figure 35 and Figure 36 , a connection surface 72 may be provided on the exhaust duct 70. The connection surface 72 may be provided at the lower end of the exhaust duct 70 and may form a surface that contacts the upper surface of the bracket body 76 in the vertical direction. In one example, the upper surface of the bracket body 76 may form a horizontal plane orthogonal to the vertical axis, and the connection surface 72 may form a plane parallel thereto.

[0513] The duct bracket 75 may further include a first duct connection portion 78 connected to the connection surface 72. In a state where the connection surface 72 contacts the bracket body 76 in the vertical direction, the first duct connection portion 78 may be detachably connected to the connection surface 72.

[0514] In one example, the first duct connection portion 78 may include a vertical protrusion 78a and a horizontal protrusion 78b. The vertical protrusion 78a may be formed to protrude upward from the bracket body 76. The horizontal protrusion 78b may be formed to protrude from the vertical protrusion 78a in the horizontal direction (more specifically, in the front-rear direction).

[0515] In one example, the horizontal protrusion 78b may protrude backward from the upper end of the vertical protrusion 78a. In the present embodiment, the first duct connection portion 78 is shown protruding from the bracket body 76 in a "Γ" shape.

[0516] The vertical protrusion 78a can pass through the slit 73 formed in the coupling surface 72 to pass through the coupling surface 72 in the vertical direction. The horizontal protrusion 78b protruding from the upper end of the vertical protrusion 78a can restrict the upward movement of the pipe support 75 while being located on the upper side of the coupling surface 72.

[0517] The slit 73 can be defined such that the entire first pipe coupling portion 78 can extend through the slit 73. When the exhaust pipe moves backward such that the horizontal protrusion 78b can move to the rear side of the slit 73 while passing through the slit 73 and being disposed above the coupling surface 72 and the coupling surface 72 contacts the upper surface of the support body 76, the horizontal protrusion 78b can restrict the upward movement of the pipe support 75 while being located on the upper side of the coupling surface 72.

[0518] The exhaust pipe 70 can be temporarily fixed to the pipe support 75 via the mating connection between the first pipe coupling portion 78 and the coupling surface 72. That is, the position of the exhaust pipe 70 relative to the pipe support 75 can be temporarily fixed via the mating connection between the first pipe coupling portion 78 and the coupling surface 72.

[0519] In one example, a plurality of first pipe coupling portions 78 can be included in the pipe support 75 and can be arranged to be spaced apart from each other by a predetermined distance in the lateral direction. Accordingly, the exhaust pipe 70 can be temporarily fixed at a plurality of points arranged along the lateral direction using the first pipe coupling portions 78.

[0520] The pipe support 75 can further include a second pipe coupling portion 79. The second pipe coupling portion 79 can be configured to couple the exhaust pipe 70 and the pipe support 75 to each other using a fastening member s such as a screw.

[0521] In one example, the fastening member s can pass through the upper surface of the support body 76 and the coupling surface 72 to couple the pipe support 75 to the exhaust pipe 70. The second pipe coupling portion 79 can be configured to be fastened to the fastening member s.

[0522] In one example, the second pipe coupling portion 79 can form a convex surface upward from the upper surface of the support body 76, and a fastening hole for fastening with the fastening member s can be defined in the second pipe coupling portion 79.

[0523] As described above, the exhaust pipe 70 can be installed on the upper surface of the cavity 11 via the pipe support 75.

[0524] In order to install the exhaust pipe 70 on the cavity 11 such that the exhaust pipe 70 can be removed from the cavity 11 as needed, it is necessary to couple the exhaust pipe 70 to the cavity 11 using a fastening member such as a screw.

[0525] However, in this case, fastening holes for screw fastening should be formed in the cavity 11, and it is not preferable to impose unnecessary damage on the cavity 11 due to the fastening holes.

[0526] In addition, during the process of fastening the screw to the cavity 11, the damage to the cavity 11 may further increase, and during the process of removing the screw from the cavity 11 or refastening the screw to the cavity 11 to disassemble and reassemble the exhaust pipe 70, the cavity 11 may be severely damaged.

[0527] To prevent breakage of the cavity 11, the exhaust pipe 70 can be joined to the cavity 11 by welding or bonding. However, in this case, it becomes very difficult to remove the exhaust pipe 70 from the cavity 11, and during the process of removing the exhaust pipe 70 from the cavity 11, the cavity 11 may be damaged.

[0528] Considering this fact, in the present embodiment, the pipe bracket 75 is joined to the cavity 11 by welding or bonding, and the exhaust pipe 70 can be detachably coupled to the pipe bracket 75.

[0529] Therefore, the cavity 11 and the pipe bracket 75 are joined to each other by welding or bonding, whereby damage to the cavity 11 due to perforation or the like can be minimized.

[0530] In addition, the exhaust pipe 70 is detachably coupled to the pipe bracket 75 joined to the cavity 11 as described above. Therefore, the exhaust pipe 70 can be easily and quickly removed from the cavity 11 as needed, and damage to the cavity 11 that may occur during the process of disassembling and reassembling the exhaust pipe 70 can be minimized.

[0531] In addition, through the fitting connection between the first pipe connection portion 78 and the connection surface 72, the connection position of the exhaust pipe 70 relative to the pipe bracket 75 can be guided, and the exhaust pipe 70 can be temporarily fixed to the pipe bracket 75. Therefore, the installation of the exhaust pipe 70 can be performed more easily and quickly.

[0532] [An example of a lamp shade]

[0533] Figure 37 is an enlarged view of the lamp shade and its surroundings, Figure 38 is Figure 37 a plan view of the lamp shade shown.

[0534] Referring to Figure 31 、 Figure 37 and Figure 38 , the lamp 8 can be provided inside the main body 10. The lamp 8 is configured to irradiate light into the cooking chamber 10a.

[0535] In one example, the lamp 8 may be installed on the upper surface of the cavity 11. At least a part of the lamp 8 may be exposed on the upper side of the cavity 11. For example, a part of the lamp 8 installed on the upper surface of the cavity 11 may be exposed in the upper space 10i.

[0536] The cooking appliance according to the present embodiment may include a lamp cover 80. The lamp cover 80 is configured to cover the lamp 8. The lamp cover 80 may cover the lamp 8 while being disposed above the cavity 11 such that the space around the lamp 8 is blocked from the upper space 10i.

[0537] In one example, the lamp cover 80 may include a cover upper surface portion 81 and a cover side surface portion 82. The cover upper surface portion 81 is configured to cover the upper side of the lamp 8, and the cover side surface portion 82 is configured to surround the lateral sides of the lamp.

[0538] In one example, the cover upper surface portion 81 may form a horizontal plane that is disposed at a predetermined distance from the upper surface of the cavity 11 in the vertical direction. The cover side surface portion 82 may form a vertical wall surface that connects the upper surface of the cavity 11 and the cover upper surface portion 81 to each other.

[0539] In one example, the lamp cover 80 may be formed in a hexahedron shape with an open lower side. The lamp 8 may also be disposed in a manner surrounded by the cover upper surface portion 81 and the cover side surface portion 82.

[0540] The lamp cover 80 may further include a close contact portion 83. The close contact portion 83 may be configured to make surface contact with the upper surface of the cavity 11 and be connected to the lower end of the cover side portion 82. In one example, the close contact portion 83 may extend horizontally from the lower end of the cover side portion 82 and may form a plane parallel to the upper surface of the cavity 11.

[0541] The close contact portion 83 may make surface contact with the upper surface of the cavity 11 and may be used to allow the lamp cover 80 to be in close contact with the upper surface of the cavity 11. Thus, the space inside the lamp cover 80 surrounding the lamp 8 can be reliably blocked from the upper space 10i, and air inflow from the upper space 10i into the lamp cover 80 can be effectively suppressed.

[0542] The lamp cover 80 of the present embodiment may be disposed between the upper surface of the cavity 11 and the upper surface of the cabinet 13 in the vertical direction. In addition, the lamp cover 80 may be disposed adjacent to the front surface of the main body 10.

[0543] According to the present embodiment, the front plate 12 may be formed such that the upper end of the front plate 12 is disposed at a position higher than the position of the upper surface of the cavity 11. The upper end surface portion 12a may be disposed at the upper end of the front plate 12. The upper end surface portion 12a may form a horizontal surface that protrudes backward and is positioned on top of the cavity 11.

[0544] The lamp cover 80 can be disposed adjacent to the front plate 12. In one example, the lamp cover 80 can be disposed at a position where the front end of the lamp cover 80 is in close contact with the rear surface of the front plate 12.

[0545] The upper surface portion 81 of the cover of the lamp cover 80 can also form an inclined surface whose vertical height varies in the front-rear direction. In one example, the upper surface portion 81 of the cover can form an inclined surface, and the vertical level of the inclined surface decreases as the upper surface portion 81 of the cover extends rearward.

[0546] The lamp cover 80 can be coupled to the front plate 12. The lamp cover 80 can include a cover coupling portion 84. The cover coupling portion 84 can protrude rearward from the lamp cover 80 to contact the upper end surface portion 12a of the front plate 12 in the vertical direction.

[0547] The cover coupling portion 84 can be formed in a shape protruding upward and rearward from the front end of the upper surface portion 81 of the cover. In one example, the cover coupling portion 84 can be formed to protrude in a "Γ" shape from the front end of the upper surface portion 81 of the cover. In one example, the coupling between the cover coupling portion 84 and the upper end surface portion 12a can be performed using a fastening member s such as a screw.

[0548] According to the present embodiment, the lamp cover 80 is coupled only to the front plate 12 and not to the cavity 11. For example, the lamp cover 80 is only in close contact with the upper surface of the cavity 11 via the close contact portion 83 and is not coupled to the cavity 11. This is intended to allow the lamp cover 80 to be detachably coupled to the main body 10 while avoiding unnecessary damage to the cavity 11.

[0549] To this end, the lamp cover 80 can be coupled to the front plate 12 via the cover coupling portion 84 and the upper end portion 12a, and thus can be detachably coupled to the main body 10. That is, the cover coupling portion 84 can be configured to couple the lamp cover 80 to the front plate 12 rather than to the cavity 11.

[0550] According to the present embodiment, at least a part of the lamp 8 is exposed inside the cooking chamber 10a to illuminate the cooking chamber 10a. In addition, in order to connect the lamp 8 to other electronic / electrical components, a part of the lamp 8 is exposed outside the cooking chamber 10a. For example, the connection between the wire for power supply and the lamp 8 can be made through the part of the lamp 8 exposed outside the cooking chamber 10a.

[0551] According to the present embodiment, the lamp 8 is installed on the upper surface of the cavity 11, and accordingly, a part of the lamp 8 is exposed to the upper space 10i, which is the space above the cavity 11. When this part of the lamp 8 is exposed to the upper space 10i, the lamp 8 may be exposed to oil vapor and heat.

[0552] The cooking gas sucked by the blowers 100 and 200 and then flowing through the upper space 10i may include oil vapor, hot steam, etc. The cooking gas including oil vapor and hot steam may contact the lamp 8 while flowing through the upper space 10i, resulting in contamination, malfunction, etc. of the lamp 8.

[0553] In consideration of this situation, in the present embodiment, the lamp cover 80 is installed in the upper space 10i. The lamp cover 80 can protect the lamp 8 from oil vapor and heat by covering the lamp 8 while being disposed above the cavity 11, so that the space around the lamp 8 is blocked from the upper space 10i.

[0554] In a conventional cooking appliance, the blowers are provided in the upper space instead of the rear space. In this case, sufficient space for installing the blowers in the upper space must be ensured. In such a conventional cooking appliance, the vertical length of the upper space should be much greater than the vertical length of the upper space 10i of the cooking appliance of the present embodiment.

[0555] In addition, since the blowers are provided in the upper space, in a conventional cooking appliance, a flow path defining member for defining an exhaust flow path in the upper space is installed in the upper space. The flow path defining member defines an exhaust flow path that connects an exhaust hole provided in the front surface of the conventional cooking appliance and the blowers to each other, so that the exhaust flow path is located in the upper space.

[0556] In a conventional cooking appliance, the flow path defining member may be formed in a shape including a pair of side walls and a bottom surface, the pair of side walls being provided to be spaced apart from each other by a predetermined distance in the lateral direction, and the bottom surface connecting the side walls to each other on its lower side. For example, the flow path defining member may be formed in a "U" shape.

[0557] The flow path defining member may be installed on the upper side of the cavity. The flow path defining member may be detachably installed on the upper side of the cavity, and the lower surface of the flow path defining member is placed on the upper surface of the cavity.

[0558] The lamp installed on the upper surface of the cavity is provided below the flow path defining member. That is, in a conventional cooking appliance, the lamp is covered by the bottom surface of the flow path defining member and is not exposed to the exhaust flow path. Therefore, in a conventional cooking appliance, no separate structure for covering the lamp is required other than the flow path defining member.

[0559] In contrast, in the cooking appliance of the present embodiment, the blowers 100 and 200 are provided in the rear space 10f. Therefore, in the cooking appliance of the present embodiment, it may not be necessary to ensure space for installing the blowers 100 and 200 in the upper space 10i either. In the cooking appliance of the present embodiment, the vertical length of the upper space 10i can be significantly reduced compared to the vertical length of the upper space of a conventional cooking appliance.

[0560] As the vertical length of the upper space 10i decreases, it becomes difficult to ensure the space required for structures such as the flow path defining member for mounting a conventional cooking appliance in the upper space 10i. Further, in the cooking appliance according to the present embodiment, the blowers 100 and 200 and the flow path defining member 30 are provided in the rear space 10f, so that the structure for defining the exhaust flow path does not need to be mounted in the upper space 10i.

[0561] As the vertical length of the upper space 10i decreases, the vertical length of the cooking appliance can be shortened, and the total size of the cooking chamber can be reduced with respect to the volume of the cooking chamber 10a. However, since structures such as the flow path defining construction of the conventional cooking appliance are not provided in the upper space 10i, the lamp 8 is exposed in the upper space 10i.

[0562] In view of this situation, in the present embodiment, the lamp shade 80 is mounted in the upper space 10i, and the lamp shade 80 can also cover the lamp 8 in a state of being disposed above the cavity 11 so that the space surrounding the lamp 8 is blocked from the upper space 10i. Accordingly, it is possible to simultaneously achieve the purpose of reducing the vertical length of the upper space 10i and the purpose of protecting the lamp 8 from oil vapor and heat.

[0563] [Other examples of lamp shades]

[0564] Figure 39 is a rear perspective view of a cooking appliance showing another example of applying a lamp shade, and Figure 40 is shown from as Figure 39 The perspective view of the lamp shade separated from the cooking appliance shown. Figure 41 is shown Figure 40 The exploded perspective view of the exploded state of the lamp shade shown, Figure 42 is an exploded perspective view showing the exploded state of the ventilation grille and the lamp shade.

[0565] Referring to Figures 39 to 41 , the lamp shade 85 can be provided in a form including the opening / closing cover 86b. The lamp shade 85 can include a cover upper surface portion 86, a cover side surface portion 87, a close contact portion 88, and a cover coupling portion 89 in a manner similar to the lamp shade shown in the above embodiment, and can further include the opening / closing cover 86b.

[0566] The through hole 86a can be defined in the upper surface of the lamp shade 85 of the present embodiment. The through hole 86a can open the upper side of the inner space of the lamp shade 85 and can be formed to extend in the vertical direction through the cover upper surface portion 86. The lamp 8 can be exposed at a position on the top of the lamp shade 85 through the through hole 86a.

[0567] The opening / closing cover 86b is installed in the lamp housing 85, more specifically, in the upper surface portion 86 of the cover, to open and close the through-hole 86a. In one example, the opening / closing cover 86b may be detachably coupled to the upper surface portion 86 of the cover. For example, the opening / closing cover 86b may cover the through-hole 86a while being located at the top of the through-hole 86a, and may be removed from the upper surface of the cover 86 while being located at the top of the cover 86.

[0568] Referring to Figures 39 to 42 , the lamp housing 85 may be disposed below one of the plurality of second exhaust holes 2. For example, at least a portion of the lamp housing 85 may be disposed below one of the plurality of second exhaust holes 2 in the vertical direction.

[0569] In one example, the cooking appliance may further include at least one ventilation grille 9. Each ventilation grille 9 may be coupled to the cabinet 13 to cover each of the second exhaust hole 3 or the cold air inlet 5. Each ventilation grille 9 may be detachably coupled to the cabinet 13.

[0570] For example, each ventilation grille 9 is disposed on the upper surface of the cabinet 13, covers the second exhaust hole 3 or the cold air inlet 5, and is lifted upward from the upper surface of the cabinet 13 to be separated from the cabinet 13.

[0571] In one example, the opening / closing cover 86b may be disposed below one of the plurality of second exhaust holes 2 in the vertical direction. In the vertical direction, the through-hole 86a may be disposed between the second exhaust hole 3 and the lamp 8, and the opening / closing cover 86b may be disposed between the ventilation grille 9 installed in the second exhaust hole 3 and the lamp 8. In a top view, when the ventilation grille 9 has been removed from the second exhaust hole 3, the opening / closing cover 86b is visible at the position on the top of the cooking appliance. In this state, the opening / closing cover 86b has been removed so that the lamp 8 is visible at the position on the top of the cooking appliance.

[0572] Since the lamp housing 85 and the opening / closing cover 86b are installed inside the main body 10 in the above-described form, the maintenance work of the lamp 8 can be performed in a state where the ventilation grille 9 and the opening / closing cover 86b are sequentially removed from the cabinet 13 and the upper surface portion 86 of the cover.

[0573] That is, the lamp housing 85 according to the present embodiment can access the lamp 8 only by a simple operation of separating the ventilation grille 9 and the opening / closing cover 86b, thereby having an effect of being able to easily and quickly perform the maintenance operation of the lamp 8.

[0574] [Exhaust through the exhaust space]

[0575] Referring to Figure 16 and Figures 31 to 33, an upper space 10i can be formed above the cavity 11. Additionally, an extended upper space 10j can be formed above the side space 10b, rather than above the electronic / electrical component chambers 10e, 10c, 10d.

[0576] As described above, the upper space 10i and the extended upper space 10j are connected to each other while being disposed above the cavity 11. Thus, the exhaust spaces 10i and 10j can be formed above the cavity 11 and the side space 10e.

[0577] The extended upper space 10j can be defined by an extension plate 18 that vertically partitions the side space 10e. In the present embodiment, by allowing the exhaust spaces 10i and 10j to be a space that includes not only the upper space 10i but also the extended upper space 10j, the extension plate 18 can be used to extend the exhaust spaces 10i and 10j in the lateral direction. Additionally, the extension plate 18 can also serve to block the side space 10e from the exhaust spaces 10i and 10j.

[0578] When the exhaust spaces 10i and 10j extend to a space that includes both the upper space 10i and the extended upper space 10j, the size of the flow path required for the air flow discharged through the exhaust spaces 10i and 10j to the second exhaust hole 3 can be increased. In particular, the size of the exhaust spaces 10i and 10j can be further increased laterally by the size of the extended upper space 10j.

[0579] That is, the extension plate 18 according to the present embodiment divides the side space 10e such that an extended upper space 10j that can be connected to the upper space 10i can be formed, thereby providing an effect of increasing the size of the exhaust spaces 10i and 10j.

[0580] As described above, in the cooking apparatus according to the present embodiment, the blowers 100 and 200 are disposed in the rear space 10i instead of the upper space 10f. Thus, since the space required for installing the blowers 100 and 200 is not needed in the upper space 10i, the vertical length of the upper space 10i can be reduced compared to the case where the blowers are installed in the upper space 10.

[0581] In the cooking appliance according to the present embodiment, one of the methods for reducing the total size of the cooking appliance while minimizing the reduction in the volume of the cooking chamber (i.e., the method for reducing the total vertical length of the cooking appliance while minimizing the reduction in the vertical length of the cooking chamber) is to reduce the vertical length of the upper space 10i.

[0582] In view of this fact, in the cooking appliance according to the present embodiment, the vertical length of the upper space 10i is set to be less than the vertical length of the upper space of a conventional cooking appliance. That is, in the cooking appliance of the present embodiment, the vertical length of the upper space 10i is set to be significantly less than the vertical length in which the rear fan assembly 100 or the corner fan assembly 200 can be provided.

[0583] As described above, when the length in the vertical direction of the upper space 10i decreases, the volume of the upper space 10i necessarily decreases. In this regard, the upper space 10i is related to exhaust. Thus, when the volume of the upper space 10i decreases, the size of the flow path required for the flow of the air discharged to the second exhaust hole 3 necessarily decreases by the amount of the volume decrease.

[0584] When the size of the flow path required for the flow of the air discharged to the second exhaust hole 3 decreases, the exhaust performance of the cooking appliance inevitably deteriorates. In addition, when the exhaust performance of the cooking appliance deteriorates, the intake performance of the cooking appliance also inevitably deteriorates, and ultimately, the performance of the cooking appliance in removing cooking gas deteriorates.

[0585] In view of this situation, in the present embodiment, the extended upper space 10e is blocked from the side space 10e via the extension plate 18 that divides the upper and lower side spaces 10j, and the extended upper space 10j is communicated with the upper space 10i. Therefore, the total size of the exhaust spaces 10i and 10j including the upper space 10i can be increased. Accordingly, the size of the flow path required for the flow of the air discharged to the second exhaust hole 3 through the exhaust spaces 10i and 10j can be effectively increased.

[0586] As described above, when the size of the flow path required for the flow of the air discharged to the second exhaust hole 3 through the exhaust spaces 10i and 10j increases, the exhaust performance of the cooking appliance can be improved accordingly, and as a result, the performance of the cooking appliance in removing cooking gas can be improved.

[0587] In one example, structures such as an exhaust duct 70 and a lamp cover 80 are disposed in the exhaust spaces 10i and 10j. These structures have shapes that protrude from the upper surface of the cavity 11 into the exhaust spaces 10a and 10j to perform their respective functions.

[0588] For example, the exhaust duct 70 is formed in a shape that protrudes from the upper surface of the cavity 11 and has a flow path defined therein for the air flow discharged from the cooking chamber. The lamp cover 80 is formed in a shape that protrudes from the upper surface of the cavity 11 to cover the upper side of the lamp and is coupled to the front plate 12.

[0589] Each of the exhaust duct 70 and the lamp cover 80 may be formed in a shape including an inclined surface. That is, each of the exhaust duct 70 and the lamp cover 80 may be formed in a shape that inevitably protrudes from the upper surface of the cavity 11 to perform respective functions, but may be formed in a shape configured to reduce the flow resistance generated by the exhaust duct 70 and the lamp cover 80 in the exhaust spaces 10a and 10j.

[0590] That is, according to the present embodiment, the sizes of the exhaust spaces 10i and 10j are increased by the extended upper space 10j, so that the size of the flow path required for the flow of air discharged through the exhaust spaces 10i and 10j to the second exhaust hole 3 is increased. Each of the exhaust duct 70 and the lamp cover 80 provided in the exhaust spaces 10i and 10j is formed in a shape in which its flow resistance can be reduced, so that the flow of air discharged through the exhaust spaces 10i and 10j to the second exhaust hole 3 can proceed smoothly.

[0591] Therefore, the cooking appliance of the present embodiment can provide cooking gas removal performance equal to or higher than that of a conventional cooking appliance having a similar cooking ability, while having a total size smaller than that of a conventional cooking appliance having a similar cooking ability.

[0592] In addition, the extension plate 18 can be used as a blocking wall that blocks the side space 10e and the exhaust spaces 10i and 10j from each other. Accordingly, the side space 10e can be blocked from the exhaust spaces 10i and 10j via the extension plate 18.

[0593] That is, a space in which the upper space 10i and the extended upper space 10j communicate with each other via the extension plate 18 is formed above the extension plate 18, while the side space 10e and the exhaust spaces 10i and 10j are blocked from each other via the extension plate 18.

[0594] According to the present embodiment, the side space 10e is connected to the lower space defined between the air inlet hole 1 and the cavity 11. Therefore, the side space 10e can be referred to as a space connected to the air inlet hole 1. In addition, the exhaust spaces 10i, 10j can be referred to as spaces communicating with the second exhaust hole 3. That is, the side space 10e can be referred to as a space related to air intake, and the exhaust spaces 10i and 10j can be referred to as spaces related to gas discharge.

[0595] The extension plate 18 can block the exhaust spaces 10i and 10j from the side space 10e, thereby blocking the space related to gas discharge from the space related to air intake. Therefore, the space related to exhaust is increased by the extended upper space 10j, and the space occupied by the side space 10e increases the space related to intake.

[0596] That is, since the exhaust spaces 10i and 10j and the side space 10e block each other via the extension plate 18, the spaces involved in gas discharge and the spaces involved in air intake can respectively ensure sufficient sizes required for gas discharge and air intake.

[0597] In addition, since the exhaust spaces 10i and 10j and the side space 10e block each other via the extension plate 18, air in the exhaust spaces 10i and 10j can be effectively prevented from being sucked back into the blowers 100 and 200 again, that is, the backflow phenomenon, thereby effectively improving the cooking gas discharge performance of the cooking appliance.

[0598] In one example, in the cooking appliance of the present embodiment, a plurality of second exhaust holes 3 may be provided. Each of the second exhaust holes 3 may be defined in the upper surface of the main body 10, may be provided at a position adjacent to the front surface of the main body 10, and may communicate with the exhaust spaces 10i and 10j.

[0599] In the main body 10, a cold air inlet 5 and a plurality of second exhaust holes 3 may be defined, and the cold air inlet 5 and the plurality of second exhaust holes 3 may be arranged in the lateral direction. In addition, one of the plurality of second exhaust holes 3 may be provided as a common exhaust hole 3a.

[0600] In the present embodiment, it is shown that the cold air inlet 5 is provided on the left side of the second exhaust holes 3, and the cold air inlet provided on the rightmost side among the plurality of second exhaust holes 3 is set as the common exhaust hole 3a.

[0601] At least a part of the common exhaust hole 3a may be arranged to overlap at least a part of the duct outlet 70c provided in the exhaust duct 70. That is, in a top view, at least a part of the duct outlet 70c may be exposed upward through the common exhaust hole 3a. Therefore, the air discharged through the duct outlet 70c can be effectively discharged through the common exhaust hole 3a.

[0602] A part of the air introduced into the electronic / electrical component chambers 10b, 10c, and 10d through the cold air inlet 5 may be introduced into the cooking chamber 10a. The air introduced into the cooking chamber 10a, together with the steam, gas, etc. generated in the cooking chamber 10a during the cooking process of the cooking appliance, may be discharged into the exhaust duct 70.

[0603] The air introduced into the exhaust duct 70 may be discharged through the duct outlet 70c, and the air discharged from the exhaust duct 70 may be discharged to the outside of the cooking appliance through the common exhaust hole 3a. That is, the common exhaust hole 3a may serve as an outlet for discharging the air discharged from the cooking chamber to the outside of the cooking appliance.

[0604] In the present embodiment, a case is shown where at least a part of the common exhaust hole 3a is provided on the left side of the extended upper space 10j. The common exhaust hole 3a may be provided above the boundary between the upper space 10i and the extended upper space 10j. That is, in the plan view of the cooking appliance, the boundary between the upper space 10i and the extended upper space 10j may be exposed at a position on the top of the cooking appliance through the common exhaust hole 3a.

[0605] In one example, substantially the left half of the common exhaust hole 3a may be provided above the upper space 10i. Additionally, the other half of the common exhaust hole 3a may be provided above the extended upper space 10j.

[0606] The common exhaust hole 3a can be used to discharge both the air discharged from the exhaust duct 70 and the air introduced into the exhaust spaces 10i and 10j by the blowers 100 and 200. That is, the steam and gas discharged from the cooking chamber and the cooking gas sucked through the blowers 100 and 200 can be discharged together through the common exhaust hole 3a.

[0607] According to the present embodiment, the exhaust spaces 10i and 10j include the upper space 10i and the extended upper space 10j, and the air sucked through the blowers 100 and 200 can flow not only into the upper space 10i but also into the extended upper space 10j. In particular, the air flowing from the blowers 100 and 200 into the extended upper space 10j can be discharged to the outside of the cooking appliance through the common exhaust hole 3a.

[0608] In this regard, the air flowing from the blowers 100 and 200 into the extended upper space 10j may not necessarily be discharged to the outside of the cooking appliance only through the common exhaust hole 3a, and can also be discharged to the outside of the cooking appliance through a second exhaust hole 3 other than the common exhaust hole 3a.

[0609] If the extension plate 18 is not provided in the main body 10, and thus the extended upper space 10j is not formed in the main body 10, the area occupied by the exhaust spaces 10i and 10j inevitably decreases to only the upper space 10i.

[0610] In this case, most of the area below the common exhaust hole 3a is occupied by the exhaust duct 70, so it is difficult to form a passage connecting the common exhaust hole 3a with the exhaust spaces 10a and 10j to each other.

[0611] Additionally, if the extension plate 18 is not provided inside the main body 10, the common exhaust hole 3a communicates directly with the side space 10e. In this case, the suction force of the rear fan assembly 100 acting on the side space 10e may affect the surrounding environment around the common exhaust hole 3a.

[0612] In this case, it is difficult for the air flowing from the blowers 100 and 200 into the exhaust spaces 10i and 10j to be discharged to the outside of the cooking appliance through the common exhaust hole 3a. As a result, only the steam and gas discharged from the cooking chamber are mainly discharged through the common exhaust hole 3a, and the cooking gas sucked by the blowers 100 and 200 may hardly be discharged.

[0613] In contrast, in the cooking appliance of the present embodiment, the side space 10e and the upper space 10j extending upward are blocked from each other via the extension plate 18, and the regions occupied by the exhaust spaces 10i and 10j can extend not only to the upper space 10i but also to the upper space 10j extending upward provided below the common exhaust hole 3a.

[0614] Therefore, the cooking appliance of the present embodiment can discharge the steam and gas discharged from the cooking chamber and the cooking gas sucked by the blowers 100 and 200 through the common exhaust hole 3a.

[0615] [Rear support member]

[0616] Figure 43 is a rear perspective view showing a state in which the rear fan assembly is removed from the cooking appliance according to the first embodiment of the present disclosure, Figure 44 is showing from Figure 43 is a rear perspective view of the rear support member separated from the cooking appliance shown, Figure 45 is a side view showing a coupling state of the cavity and the rear support member. Figure 46 is showing as Figure 45 is a bottom perspective view showing a state in which a coupling portion between the cavity and the rear support member shown is enlarged. Figure 47 is a side view showing a state in which the rear plate is coupled to the rear support member shown as Figure 45 and Figure 48 is a side cross-sectional view showing a coupling structure between the cavity, the rear support member, and the rear plate.

[0617] Referring to Figures 43 to 45 , the cooking appliance of the present embodiment may include a rear support member 90. The rear support member 90 may be provided at the rear of the cavity 11.

[0618] As described above, the front plate may be provided in front of the cavity 11. When the cavity 11 is interposed between the front plate 12 and the rear support member 90, the front plate 12 and the rear support member 90 may be spaced apart from each other in the front-rear direction and may be coupled to the cavity 11.

[0619] In one example, the front plate 12 may be coupled to the front surface of the cavity 11, and the rear support member 90 may be coupled to the rear surface of the cavity 11. In another example, the front plate 12 may be integrally formed with the cavity 11 to constitute the front surface of the cavity 11.

[0620] According to the present embodiment, the front plate 12 may be formed such that the lower end 12b of the front plate 12 is disposed at a vertical height lower than the vertical height of the bottom surface of the cavity 11. For example, at least a portion of the front plate 12 may be disposed between the cavity 11 and the bottom plate 14.

[0621] Similar to the front plate 12, the rear support member 90 may be formed such that the lower end of the rear support member 90 is disposed at a vertical height lower than the vertical height of the bottom surface of the cavity 11. For example, at least a portion of the rear support member 90 may be disposed between the cavity 11 and the bottom plate 14.

[0622] To this end, at least a portion of the rear support member 90 may protrude to a position lower than the position of the bottom surface of the cavity 11. The rear support member 90 may contact the bottom surface of the cavity 11 while being disposed at a vertical height lower than the vertical height of the cavity 11, and may support the cavity 11.

[0623] The rear support member 90 may include a front coupling portion 91 and a lower support 92. The front coupling portion 91 is configured to be coupled to the rear surface of the cavity 11. In addition, the lower support 92 may protrude downward from the front coupling portion 91.

[0624] The lower end of the lower support 92 may be disposed at a position lower than the position of the bottom surface of the cavity 11. The lower support 92 may contact the bottom surface of the cavity 11 while being disposed at a position lower than the position of the cavity 11, and may support the front coupling portion 91 and the cavity 11 coupled to the front coupling portion 91.

[0625] Preferably, the lower end of the lower support 92 may be disposed at a position corresponding to the position of the lower end 12b of the front plate 12. For example, the protruding length of the lower support 92 with respect to the bottom surface of the cavity 11 may be set to be the same as the protruding length of the front plate 12 with respect to the bottom surface of the cavity 11. Accordingly, the rear support member 90 may support the cavity 11 such that the cavity 11 can be maintained in a substantially horizontal state.

[0626] In the front-rear direction, the rear support member 90 may be disposed between the cavity 11 and the rear plate 15. The rear support member 90 may be coupled to the cavity 11 and the rear plate 15.

[0627] Accordingly, the rear support member 90 may further include a rear coupling portion 93 and a connection portion 94. The rear coupling portion 93 is configured to be coupled to the front surface of the rear plate 15. Additionally, the connection portion 94 projects rearward from the front coupling portion 91 and may connect the front coupling portion 91 and the rear coupling portion 93 to each other.

[0628] The connection portion 94 may be disposed in the rear space 10f and may be disposed below the rear fan assembly 100. In the vertical direction, the connection portion 94 may be disposed between the rear fan assembly 100 and the bottom plate 14. The connection portion 94 is configured such that air in the rear space 10f can flow in the vertical direction while flowing through the connection portion 94.

[0629] Accordingly, the rear support member 90 may have a vertical through hole 94a defined therein. The vertical through hole 94a forms a space between the cavity 11 and the bottom plate 14, that is, forms a passage communicating the lower space and the rear fan assembly 100.

[0630] In one example, the connection portion 94 may constitute a horizontal plane blocking the lower space and the rear fan assembly 100, and the vertical through hole 94a may be formed to extend through the connection portion 94 in the vertical direction. The vertical through hole 94a may constitute a passage required for air introduced into the lower space through the air intake hole 1 to flow through the rear support member 90 and flow toward the rear fan assembly 100.

[0631] That is, the connection portion 94 can be used to maintain the interval between the cavity 11 and the rear plate 15, thereby ensuring sufficient space required for air flow in the rear space 10f.

[0632] Referring to Figures 44 to 47 , the front coupling portion 91 may be coupled to the rear surface of the cavity 11 while contacting the rear surface of the cavity 11 in the front-rear direction.

[0633] The coupling between the cavity 11 and the front coupling portion 91 may be performed via at least one of coupling using fastening members s such as screws or mating coupling. In one example, at least one of a mating coupling portion 91a and a fastening hole 91b may be provided in the front coupling portion 91. In the present embodiment, it is shown that both the mating coupling portion 91a and the fastening hole 91b are provided in the front coupling portion 91.

[0634] The mating coupling portion 91a may be detachably coupled to the rear surface of the cavity 11. In one example, the lower end 11c of the rear surface of the cavity 11 may be formed to project downward beyond the lower surface of the cavity 11. The mating coupling portion 91a is configured such that the lower end 11c of the rear surface of the cavity 11 can be mated and coupled to the mating coupling portion 91a.

[0635] In one example, the mating coupling portion 91a may be formed to protrude backward from the front coupling portion 91 in an "L" shape, and the lower end 11c of the rear surface of the cavity 11 may be fitted between the front surface of the front coupling portion 91 and the rear surface of the mating coupling portion 91a.

[0636] When assembling the cooking appliance, in a state where the cavity 11 is turned upside down so that the bottom surface of the cavity 11 faces upward, and in a state where the rear support member 90 is turned upside down so that the lower support member 92 faces upward, the rear support member 90 contacts the rear surface of the cavity 11, so that the lower end 11c of the rear surface of the cavity 11 is fitted into the mating coupling portion 91a. Thus, the mating coupling between the cavity 11 and the rear support member 90 can be achieved.

[0637] The rear support member 90 may be temporarily fixed to the cavity 11 via the mating coupling between the cavity 11 and the rear support member 90 achieved in the above manner. In a state where the rear support member 90 is temporarily fixed to the cavity 11 in this way, the front coupling portion 91 may contact the rear surface of the cavity 11 in the front-rear direction.

[0638] In this state, a fastening member s such as a screw is fastened to the fastening hole 91b, so that the rear support member 90 can be firmly coupled to the cavity 11.

[0639] That is to say, via the mating coupling between the cavity 11 and the mating coupling portion 91a, the coupling position of the rear support member 90 relative to the cavity 11 can be guided, and the rear support member 90 can be temporarily fixed to the cavity 11. Therefore, the installation of the rear support member 90 can be performed more easily and quickly.

[0640] The rear support member 90 mounted on the rear side of the cavity 11 as described above can support the cavity 11 so that the cavity 11 does not fall backward during the assembly process of the cooking appliance.

[0641] As described above, the front panel 12 is installed on the front side of the cavity 11, and the lower end 12b of the front panel 12 protrudes to a position lower than the bottom surface of the cavity 11. Therefore, when the front panel 12 is first installed on the cavity 11 and the bottom plate 14 or the rear plate 15 has not been installed on the cavity, due to the difference in the vertical lengths between the front side and the rear side of the cavity 11, the cavity 11 is likely to fall backward.

[0642] Considering this situation, in the present embodiment, the rear support member 90 may be installed on the rear side of the cavity 11, and the rear side of the cavity 11 may be supported by the rear support member 90. That is, in the present embodiment, the front panel 12 and the rear support member 90 (with the cavity 11 therebetween) are provided in the front-rear direction and can support the cavity 11 while being respectively disposed on two opposite sides in the front-rear direction of the cavity 11.

[0643] Therefore, even in a state where the front plate 12 is first installed on the cavity 11 and the bottom plate 14 or the rear plate 15 is not yet installed on the cavity, the cavity 11 does not tilt backward and can maintain a stable posture without tilting forward or backward.

[0644] That is, the rear support member 90 according to the present embodiment is for stably maintaining the posture of the cavity 11 so that the cavity 11 does not tilt backward during the assembly of the cooking appliance, thereby facilitating the assembly of the cooking appliance in a relatively stable environment. Therefore, various safety accidents that may occur due to the tilting of the cavity 11 during the assembly of the cooking appliance can be suppressed.

[0645] In addition, the rear support member 90 can be coupled to at least one of the rear plate 15 and the bottom plate 14, as Figure 47 and Figure 48 shown. In the present embodiment, it is shown that the rear support member 90 is coupled to both the rear plate 15 and the bottom plate 14.

[0646] As described above, the rear coupling portion 93 can be coupled to the rear plate 15. The lower end of the lower support member 92 can be coupled to the bottom plate 14. The rear support member 90 coupled to each of the rear plate 15 and the bottom plate 14 stably supports the rear plate 15 and the bottom plate 14 on the cavity 11, thereby effectively improving the structural stability of the cooking appliance.

[0647] In addition, the rear support member 90 can provide an effect of increasing the suction flow rate by maintaining the interval between the cavity 11 and the rear plate 15, thereby ensuring sufficient space required for air flow in the rear space 10f.

[0648] [Further Examples of Cooking Appliances]

[0649] Figure 49 is a rear perspective view showing a state in which the cabinet is removed from the cooking appliance according to the second embodiment of the present disclosure, Figure 50 is a rear perspective view showing a state in which the cabinet is removed from the cooking appliance according to the third embodiment of the present disclosure, Figure 51 is a rear perspective view showing a state in which the cabinet is removed from the cooking appliance according to the fourth embodiment of the present disclosure.

[0650] As Figures 49 to 51 shown, the main difference between the cooking appliance shown and the cooking appliance shown in the above embodiment lies in the presence or absence of the corner fan assembly 200 (see Figure 5 ). As Figures 49 to 51 shown, only the rear fan assembly 100 is provided in the cooking device, and the corner fan assembly 200 is not provided.

[0651] Therefore, as Figures 49 to 51There is a difference between the blower output of the cooking appliance shown and the blower output of the cooking appliance shown in the above-described embodiment. That is, compared with a cooking appliance including both a corner fan assembly 200 and a rear fan assembly 100, the output of the blower in the cooking appliance as shown in Figures 49 to 51 is relatively reduced.

[0652] As shown in Figures 49 to 51 , the cooking appliance can employ a main body 10 having a shape substantially the same as the shape of the main body of the cooking appliance shown in the above-described embodiment. That is to say, the cooking appliance according to the present embodiment can be provided as various types of cooking appliances, which employ only one type of common main body but have only different blower outputs.

[0653] The cooking appliance according to the present embodiment can provide the effect of easily and quickly manufacturing various types of cooking appliances at low cost. Hereinafter, various embodiments of the cooking appliance for achieving the above object are shown.

[0654] Referring to Figure 49 , except for the blower and the flow path defining member 300, the structure of the cooking appliance according to the second embodiment of the present disclosure is substantially the same as the structure of the cooking appliance shown in the above-described embodiment.

[0655] That is, the main difference between the cooking appliance according to the second embodiment of the present disclosure and the cooking appliance shown in the above-described embodiment lies in the blower and the flow path defining member 300.

[0656] The flow path defining member 300 of the present embodiment may include a first flow path plate 31 and a fastening plate 33. For example, the flow path defining member 300 of the present embodiment may also be provided in such a manner that the second flow path plate 32 is omitted from the flow path defining member 30 (refer to Figure 6 ).

[0657] In one example, the flow path defining member 300 of the present embodiment may be provided in a form in which the first flow path plate 31 and the fastening plate 33 are integrally formed with each other. In another example, the flow path defining member 300 may be provided in a form in which the first flow path plate 31 and the fastening plate 33 are separately formed and assembled with each other.

[0658] Therefore, a structure that can block the first suction hole 112 and the first discharge hole 114 from each other is not provided on the left side of the rear fan assembly 100. In addition, the corner spaces 10g, 10h, and more specifically the lower corner space 10h, remain in an empty state.

[0659] The cooking appliance of the present embodiment may further include a lid 36. The lid 36 is configured to cover the through hole 41b formed in the lateral support 41 (see Figure 21)。The lid 36 can be coupled to the lateral support 41 to close the discharge hole 41a. Due to the lid 36, unnecessary passages between the corner spaces 10g, 10h and the exhaust flow path A can be closed.

[0660] Referring to Figure 50 , the flow path defining member 400 provided in the cooking apparatus according to the third embodiment of the present disclosure can be configured to include a first flow path plate 31, an extension plate 34, and a fastening plate 33.

[0661] In one example, the flow path defining member 400 of the present embodiment can be provided in a form in which the first flow path plate 31, the extension plate 34, and the fastening plate 33 are integrally formed with each other. In another example, the flow path defining member 300 can be provided in a form in which the first flow path plate 31, the extension plate 34, and the fastening plate 33 are separately formed and assembled with each other.

[0662] In the flow path defining member 400, the first flow path plate 31 can define the right boundary surface of the exhaust flow path A. The extension plate 34 forms the left boundary surface of the exhaust flow path A, is provided on the left side of the rear fan assembly 100, and constitutes a wall that blocks the first suction hole 112 and the first discharge hole 114.

[0663] In addition, referring to Figure 51 , the cooking appliance according to the fourth embodiment of the present disclosure can include a flow path defining member 30 having the same shape as the shape shown in the first embodiment of the present disclosure. In addition, the cooking appliance according to the fourth embodiment of the present disclosure can further include a lid 36 having the same shape as the shape shown in the second embodiment of the present disclosure.

[0664] Therefore, the right boundary surface of the exhaust flow path A can be defined by the first flow path plate 31. In addition, on the left side of the rear fan assembly 100, the lower boundary surface of the exhaust flow path A can be defined by the second flow path plate 32. In addition, the left boundary surface of the exhaust flow path A can be defined by the lateral support 41 and the lid 36.

[0665] Although the present disclosure has been described above with reference to the embodiments shown in the drawings, this is only an example, and those skilled in the art will understand that various modifications and other equivalent embodiments can be made therefrom. Therefore, the true technical protection scope of the present disclosure should be determined by the appended claims.
