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] Cooking utensils are household appliances for cooking food, and are appliances installed in a kitchen space to cook food according to a user's intention. Such cooking utensils can be variously classified according to the type of heat source, form, or fuel to be used.

[0003] When cooking appliances are classified according to the type of food being cooked, they can be classified into open cooking appliances and closed cooking appliances according to the type of space in which the food is placed. Closed cooking appliances include ovens, microwave ovens, etc., and open cooking appliances include cooktops, stoves, etc.

[0004] Closed-type cooking appliances are appliances that enclose the space where food is placed and heat the enclosed space to cook the food. In closed-type cooking appliances, a cavity (i.e., a cooking chamber) is located within the main body. This cavity is the enclosed space where food is placed and cooked. This cooking chamber is the actual space where the food is cooked. A heat source is located inside or outside the cooking chamber to heat the cooking chamber.

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

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

[0007] Recently, microwave ovens with a range hood combined with a range hood have been released, also known as OTR (Over the Range) type microwave ovens. OTR type microwave ovens with a range hood have a range hood function that exhausts air containing foreign matter generated during cooking (hereinafter referred to as "cooking gas") from a cooking appliance installed thereunder, or filters the cooking gas and then exhausts the filtered gas into the oven.

[0008] A fan for drawing in and exhausting air is provided in a microwave oven combined with a range hood. Such a fan is usually provided at the top of a cavity defining a cooking chamber. That is, in a microwave oven with a range hood, the fan is usually provided at the top of the cavity.

[0009] However, when the fan is positioned as described above, the distance between the fan and the suction hole at the lower end of the microwave oven combined with a range hood is greater than the vertical length of the oven cavity. As mentioned above, the increased distance between the suction hole and the fan inevitably reduces the cooking gas collection performance of the microwave oven equipped with a range hood. This is because the flow rate of the suction airflow generated by the fan decreases inversely proportional to the square of the distance from the fan to the suction hole.

[0010] In addition, when the fan is arranged 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 the increased vertical length is installed in the upper cabinet, the possibility of the microwave oven combined with the range hood protruding downward beyond the upper cabinet increases.

[0011] When the microwave oven with a range hood protrudes downward beyond the upper cabinet, it is not aesthetically pleasing and a problem may occur in that a distance between a stove installed under the upper cabinet and the microwave oven with a range hood is small.

[0012] When the distance between the stove and the microwave oven with a range hood is smaller as the microwave oven with a range hood protrudes downward beyond the upper cabinet, there may occur a problem that the microwave oven with a range hood blocks the view of a user who wants to use the stove and a problem that the cooking area of the stove is smaller.

[0047] Technical Effects

[0048] The cooking appliance of the present disclosure is configured such that the blower for providing the oil fume extraction function is disposed behind the cavity rather than above the cavity, thereby suppressing an increase in the vertical length of the cooking appliance while providing the oil fume extraction function.

[0049] In addition, according to the present disclosure, the blower can be set in the rear space which is a space ensured for installing a convection module, etc., rather than in the upper space and side space defined inside the main body, thereby reducing the vertical length of the cooking appliance and effectively suppressing the increase in the vertical and lateral lengths of the cooking appliance, thereby effectively suppressing the increase in the vertical and lateral lengths of the cooking appliance and simultaneously providing a fume extraction function with improved performance.

[0050] In addition, the cooking appliance of the present disclosure adopts a structure in which the blower is disposed in a rear space connected to and aligned with the exhaust hole in a straight line, thereby minimizing airflow loss inside the cooking appliance, thereby further improving cooking gas removal performance.

[0051] 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 gas flow while reducing the resistance of the flow path around the exhaust hole, thereby effectively improving the cooking gas discharge performance.

[0052] In addition, according to the present disclosure, the force provided by the suction force of the fan assembly can be applied to the electronic / electrical component chamber through the connecting flow path, thereby allowing the air flow in the electronic / electrical component chamber to proceed more smoothly, so that the electronic / electrical components arranged in the electronic / electrical component chamber can be cooled more effectively.

[0053] In addition, the cooking appliance of the present disclosure allows air introduced into the electronic / electrical component chamber to flow from the electronic / electrical component chamber into the fan assembly through the connecting flow path, thereby effectively increasing the suction flow rate of the fan assembly, thereby providing more improved cooking gas removal performance.

[0054] In addition, according to the present disclosure, the overall size of the exhaust space may be increased by the extension plate that divides the side space into upper and lower portions, thereby effectively increasing the size of a flow path required for airflow discharged to the exhaust holes through the exhaust space.

[0055] Furthermore, according to the present disclosure, since the extension plate vertically divides the side space, each of the space involved in gas exhaust and the space involved in air intake can be ensured to have a sufficient size required for intake or exhaust. Therefore, the cooking appliance of this embodiment can provide cooking gas removal performance equal to or higher than that of conventional cooking appliances with similar cooking capabilities, while having an overall size smaller than that of conventional cooking appliances with similar cooking capabilities.

[0056] Furthermore, the cooking appliance of the present disclosure is configured to allow steam and gas exhausted from the cooking chamber and cooking gas drawn in by the blower to be exhausted through a common exhaust hole, thereby effectively increasing the area of the exhaust hole for gas exhaust and thereby more smoothly exhausting the cooking gas through the exhaust hole.

[0057] In addition, the cooking appliance of the present disclosure may include an exhaust duct, which is formed in a structure in which the vertical length of the exhaust duct decreases as the exhaust duct extends toward the rear side, thereby effectively suppressing the increase in flow resistance caused by the exhaust duct, while smoothly discharging the steam and gas exhausted from the cooking chamber to the outside of the cooking appliance.

[0058] Furthermore, the cooking appliance of the present disclosure allows the exhaust duct to be detachably coupled to a duct bracket engaged with 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 disassembly and reassembly of the exhaust duct.

[0059] In addition, the cooking appliance disclosed herein includes a rear support member, which serves to stably maintain the posture of the cavity so that the cavity will not tilt backward during the assembly of the cooking appliance, thereby enabling the assembly of the cooking appliance to be conveniently carried out in a relatively stable environment and suppressing the occurrence of various safety accidents that may occur due to the tilting of the cavity during the assembly of the cooking appliance.

[0060] 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.

[0061] In addition, the cooking appliance of the present disclosure maintains a spacing between the cavity and the rear plate via the rear support member, so that sufficient space required for air flow in the rear space can be ensured, thereby effectively increasing the suction flow rate.

[0062] In addition, the cooking appliance of the present disclosure includes a shielding member for shielding the lower electronic / electrical component chamber while being located on the top of the lower electronic / electrical component chamber, thereby allowing air to flow smoothly into the lower electronic / electrical component chamber and at the same time significantly reducing the risk of fire spreading due to flames generated inside the cooking appliance.

[0063] In addition, the cooking appliance of the present disclosure includes a lamp cover that covers the lamp while being located on the top of the lamp, thereby satisfying the purpose of reducing the vertical length of the cooking appliance and the purpose of protecting the lamp from oil vapor and heat.

[0064] In addition, the lampshade according to the present disclosure is configured to have a structure in which its vertical length decreases as it extends toward the rear side, so that the lamp can be effectively protected from oil vapor and heat while effectively suppressing an increase in flow resistance caused by the lampshade.

[0065] In addition, according to the present disclosure, a simple work of removing the ventilation grille and the opening / closing cover can allow the user to access the lamp, thereby enabling maintenance and repair of the lamp to be performed in a simple and quick manner.

[0152] Reference Figures 3 to 7 Air intake holes 1 may be provided in the bottom surface of the cooking appliance. In one example, air intake holes 1 may be defined in bottom plate 14. Air intake holes 1 may form a passage for introducing cooking gases into the cooking appliance, such that the passage is defined at the lower end of the cooking appliance. In this embodiment, a pair of air intake holes 1 are shown disposed below blowers 100 and 200.

[0153] The bottom plate 14 may be provided spaced downwardly a predetermined distance from the bottom surface of the cavity 11. Thus, a lower space (not indicated by a reference numeral) may be defined between the bottom surface of the cavity 11 and the bottom plate 14. Due to the lower space formed as described above, a space required for introducing external air into the cooking appliance through the air intake hole 1 may be provided above the air intake hole 1.

That is, the second exhaust hole 3 may be provided on a side adjacent to the door 20 and may be provided closer to the front side than the first exhaust hole 2.

[0159] The first exhaust hole 2 may constitute a passage for discharging the cooking gas drawn into the cooking appliance to the outside, and the second exhaust hole 3 may constitute a passage for discharging the cooking gas drawn into the cooking appliance to the indoor space.

[0160] In one example, the first exhaust hole 2 may be provided in an area vertically overlapping with an upper cabinet accommodating the cooking appliance. In addition, the second exhaust hole 3 may be provided at a position protruding beyond the upper cabinet in a forward direction.

[0161] In addition, the first exhaust hole 2 may be provided substantially at the center in the lateral direction of the body 10. In addition, a plurality of second exhaust holes 3 may be provided in the lateral direction and may be positioned at the front side of the upper surface of the body 10.

[0162] As described above, the first exhaust hole 2, positioned approximately at the center of the main body 10 in the transverse direction, can be connected to an exhaust duct leading to the outside. A plurality of second exhaust holes 3 arranged transversely can discharge cooking gases from the front of the upper cabinet to the top of the cooking appliance. In this manner, the cooking gases can be discharged through the second exhaust holes 3 while being filtered within the cooking appliance.

[0163] Similar to the first exhaust hole 2, the third exhaust hole 4 can form a passage for exhausting cooking gases drawn into the cooking appliance to the outside. The third exhaust hole 4 can be positioned facing the wall surface on which the cooking appliance is mounted. The third exhaust hole 4 can be mounted on the rear surface of the main body and can be connected to an exhaust duct connected to the outside.

[0164] The third exhaust hole 4 may be defined in the rear surface of the cooking appliance and may be disposed above the blowers 100 and 200. In one example, the third exhaust hole 4 may be defined in the rear plate 15. The third exhaust hole 4 may be formed to extend through the rear plate 15 in the front-rear direction.

[0165] A space may be formed in the body 10. The space may be provided between the cavity 11 and the box 13.

[0166] 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. In addition, the rear space 10f may be provided on the rear side of the cavity 11.

[0167] 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 box body 13. In addition, the rear space 10f may be a space defined between the rear surface of the cavity 11 and the rear plate 15.

[0168] The side spaces 10e and the rear space 10f may be connected to the lower space. The side spaces 10e and the rear space 10f may be connected to the lower space in a vertical direction or in a horizontal direction. The air intake hole 1 may be connected to the lower space. The side spaces 10e and the rear space 10f may be connected to the air intake hole 1 through the lower space.

[0170] In addition, a space provided on the side surface and rear side of the cavity 11 may be defined inside the body 10. The space may be the rear space 10f, the side space 10e, or may be the electronic / electrical component chambers 10b, 10c, and 10d.

[0171] For example, this space may be provided in a rear corner portion of the interior of the main body 10. Hereinafter, the space provided behind the electronic / electrical component chambers 10b, 10c, and 10d is referred to as a 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, and 10d, may communicate with each other through the corner space 10e.

[0172] The blowers 100 and 200 may be disposed inside the body 10. More specifically, the blowers 100 and 200 may be disposed in a space, ie, a space between the cavity 11 and the housing 13. The blowers 100 and 200 may include at least one fan assembly 100 and 200.

[0173] The fan assemblies 100 and 200 can generate an airflow for drawing cooking gas outside the cooking appliance and exhausting the cooking gas outside the cooking appliance. The fan assemblies 100 and 200 can introduce cooking gas into the main body 10 through the air intake hole 1 and exhaust the introduced cooking gas out of the main body through the exhaust holes 2, 3 and 4.

[0174] At least one of the fan assemblies 100 and 200 provided in the blowers 100 and 200 may be provided in the rear space 10f. Therefore, cooking gas introduced into the main body 10 through the air intake hole 1 may flow through the rear space 10f and then be discharged through the first exhaust hole 2 or the second exhaust hole 3. The detailed arrangement structure of the fan assemblies 100 and 200 will be described later.

[0175] In addition, an upper space 10i may be further provided inside the main body 10. The upper space 10i may be provided above the cavity 11.

[0176] For example, the upper space 10i may be defined between an upper surface of the cavity 11 and an upper surface of the box body 13. The upper space 10i may communicate with the rear space 10f.

[0177] That is, the air introduced into the rear space 10f can flow through the upper space 10i and be discharged to the outside of the cooking appliance through the exhaust holes 2, 3, and 4. In addition, the air introduced into the side space 10e can also flow through the rear space 10f and the upper space 10i and be discharged to the outside of the cooking appliance through the exhaust holes 2, 3, and 4.

[0178] [Fan assembly]

[0179] Figure 8 It is shown from Figure 6 A perspective view of the cooking appliance with the rear fan assembly separated is shown. Figure 9 It is shown from Figure 6 A perspective view of the cooking appliance is shown with the corner fan assembly separated.

[0180] Reference Figure 1 and Figures 7 and 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 a rear fan assembly 100.

[0181] The rear fan assembly 100 may include a fan housing 110 , a fan wheel 120 , and a fan motor.

[0182] The fan housing 110 forms the exterior of the rear fan assembly 100 and internally houses the impeller 120. A first suction hole 112 may be formed in a side portion of the fan housing 110. The first suction hole 112 may constitute a passage for drawing air from outside the rear fan assembly 100 into the impeller 120 within the fan housing 110.

[0183] In the present embodiment, the fan housing 110 is shown to be formed into a shape including a horizontally extended cylindrical shape, wherein two opposite sides of the fan housing are open, and each of the two opposite open sides of the fan housing 110 can be set as a first suction hole 112 .

[0184] An accommodation space for accommodating the impeller 120 may be formed inside the fan housing 110 .

[0185] The accommodation space for accommodating the wind wheel 120 may be formed inside the fan housing 110. In addition, the inner circumference of the fan housing 110 defining the accommodation space may be formed as a curved surface surrounding the outer circumference of the wind wheel 120.

[0186] A first discharge hole 114 may be provided at an upper side of the fan housing 110. The first discharge hole 114 constitutes a passage through which air drawn into the accommodation space accommodating the impeller 120 is discharged to the outside of the blowers 100 and 200.

[0187] The first discharge hole 114 may be formed to vertically penetrate the fan housing 110 . Therefore, air drawn into the inside of the fan housing 110 from the lateral direction through the first suction hole 112 may be discharged to a position on the top of the fan housing 110 through the first discharge hole 114 .

[0188] The wind wheel 120 is configured to rotate around an axis extending in a transverse direction. A space is formed inside the wind wheel 120 into which air drawn through a side portion of the wind wheel 120 flows.

[0189] The wind wheel 120 may be connected to the rotating shaft of the fan motor. The rotating shaft of the fan motor rotates around an axis extending in the transverse direction, and the wind wheel 120 connected to the rotating shaft of the fan motor may rotate together with the rotating shaft of the fan motor around an axis extending in the transverse direction.

[0190] The rear fan assembly 100 configured as above may be disposed inside the body 10 and may be disposed in at least one of the rear space 10f and the corner space 10e. In this embodiment, the rear fan assembly 100 is shown as being disposed in the rear space 10f.

[0191] 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 a fan motor is provided between the pair of wind wheels 120 provided in a transverse direction.

[0192] In the rear fan assembly 100, the fan motor can rotate a pair of impellers 120 respectively arranged on two opposite sides in the lateral direction thereof. Each impeller 120 can be accommodated in each fan housing of a pair of fan housings 110 respectively arranged on two opposite sides in the lateral direction of the fan motor.

[0193] As described above, the rear fan assembly 100, which includes a fan motor, a pair of wind wheels 120 and a fan housing 110, can suck air through a pair of first suction holes 112 respectively arranged 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 arranged in the upper surface of the rear fan assembly 100 and along the lateral direction.

[0194] The rear fan assembly 100 can be configured as follows: a pair of impellers 120 are respectively arranged on two opposite sides of the fan motor in the transverse direction, and a pair of fan housings 110 are respectively arranged on two opposite sides of the fan motor in the transverse direction. Hereinafter, the assembly of impellers 120 and fan housings 110 will be referred to as a "fan module." In this regard, the rear fan assembly 100 can be configured in a form in which the pair of fan modules are connected to two opposite sides of the fan motor in the transverse direction.

[0195] The rear fan assembly 100 may be disposed 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 may be disposed in a space communicating with the air intake hole 110 and the exhaust holes 2, 3, and 4, and may draw air through the air intake hole 110 and discharge the air toward the exhaust holes 2, 3, and 4.

[0196] In addition, the rear fan assembly 100 may be disposed at the center of the rear space 10f in the lateral direction. That is, the rear fan assembly 100 may be disposed at approximately the center of the rear side of the interior of the cooking appliance.

[0197] According to this embodiment, the first exhaust hole 2 can be positioned approximately at the center of the body 10 in the transverse direction, can be defined in the upper surface of the housing 13, and can be positioned relatively close to the rear end thereof. Furthermore, the first exhaust hole 2 can be positioned in an area vertically overlapping with the fan assemblies 100 and 200. In other words, the first exhaust hole 2 can be positioned in an area vertically overlapping with the rear space 10a and the rear fan assembly 100.

[0198] In addition, the third exhaust hole 4 can be provided at a substantially center in the lateral direction of the main body 10, and can be provided in the rear plate 15 and at a position closer to the upper end of the rear plate 15. That is, the third exhaust hole 4 can be provided in the rear surface of the main body 10, but can be provided at a position adjacent to the first exhaust hole 2.

[0199] 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 disposed in the rear space 10f. The first exhaust hole 2 and the third exhaust hole 4, particularly the first exhaust hole 2, can be vertically aligned with the rear fan assembly 100 along the rear space 10f.

[0200] That is, the rear fan assembly 100, the rear space 10f, the first exhaust hole 2 and the third exhaust hole 4 may overlap 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 may be aligned with each other in a line along the vertical direction.

[0201] Therefore, the air flow performed by the operation of the rear fan assembly 100 may have the same linear direction 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.

[0202] When the air flows in a straight line as described above, the resistance to the airflow is reduced, so that the air flow can be carried out more smoothly. Therefore, the air suction and discharge performance of the rear fan assembly 100 can be improved, thereby correspondingly improving the cooking gas removal performance of the cooking appliance.

[0203] The blowers 100 and 200 of this embodiment may include a plurality of fan assemblies 100 and 200 arranged in a transverse direction. In one example, the blowers 100 and 200 may further include an angular fan assembly 200, such as Figure 7 and Figure 9 The rear fan assembly 100 and the corner fan assembly 200 may be disposed laterally and arranged in the rear space 10f.

[0204] The angular fan assembly 200 can be provided in the form of a fan module connected to a fan motor. In one example, the angular fan assembly 200 can be provided in the form of a fan module connected to the underside of the fan motor.

[0205] In the corner fan assembly 200 , the impeller 220 may rotate about a vertical axis. The second suction hole 212 may be provided in a lower surface of the fan housing 210 , and the second discharge hole 224 may be provided at a side surface of the fan housing 210 .

[0206] That is, the corner fan assembly 200 may be provided in a configuration similar to a configuration in which approximately half of the rear fan assembly 100 stands upright in a vertical direction.

[0207] The rear fan assembly 100 and the corner fan assembly 200 can be disposed together in the rear space 10f. In one example, the rear fan assembly 100 and the corner fan assembly 200 can be disposed laterally and disposed in the rear space 10f.

[0208] For example, the corner fan assembly 200 may be disposed adjacent to the electronic / electrical component rooms 10b, 10c, and 10d on one side of the body, and the rear fan assembly 100 may be disposed adjacent to the side space 10e on the other side of the body.

[0209] At least a portion of the corner fan assembly 200 may be disposed in the corner space 10e. In one example, a majority of the corner fan assembly 200 may be disposed in the corner space 10e, and the second suction hole 212 of the corner fan assembly 200 may also be disposed in the corner space 10e. The corner fan assembly 200 may be spaced a predetermined distance laterally from the rear fan assembly 100.

[0210] 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 .

[0211] 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 a case where the blowers 100 and 200 include only a plurality of rear fan assemblies 100 .

[0212] For example, the lateral lengths of the blowers 100 and 200 including one rear fan assembly 100 and one corner fan assembly 200 may be measured shorter than the lateral length of the blower 200 including a pair of rear fan assemblies 100 disposed in the lateral direction.

[0213] Corner fan assembly 200 may include only one fan module among the fan modules included in rear fan assembly 100 and may include a fan module standing upright in a vertical direction. Therefore, the lateral length of corner fan assembly 200 is necessarily shorter than that of rear fan assembly 100.

[0214] Considering this configuration, the blowers 100 and 200 of the present embodiment including the corner fan assembly 200 can be provided in a size much smaller than that of the rear fan assembly 100 or a blower including only the rear fan assembly 100 .

[0215] 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 is reduced.

[0216] In view of this, when the size of a cooking appliance is small so that the plurality of rear fan assemblies 100 cannot be accommodated inside the cooking appliance, the blowers 100 and 200 of the present embodiment are very suitable for application to the cooking appliance.

[0217] In addition, in the angular fan assembly 200, the second suction hole 212 can 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 angular 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.

[0218] 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.

[0219] That is, 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 largely offset by the performance improvement obtained by reducing the distance between the second suction hole 212 and the air intake hole 1.

[0220] In consideration of this fact, it can be assessed that the blowers 100 and 200 of the present embodiment can provide an effect of contributing to the downsizing of cooking appliances while providing the same or higher cooking gas removal performance as another type of blower.

[0221] The cooking appliance of the present embodiment including the blowers 100 and 200 may provide improved cooking gas removal performance while maintaining a compact size.

[0222] In addition, refer to Figures 5 to 7 , the rear fan assembly 100 and the corner fan assembly 200 may be positioned to overlap the cavity 11 in the front-to-rear direction. That is, the rear fan assembly 100 and the corner fan assembly 200 may be disposed between the upper surface and the lower surface of the cavity 11 in the vertical direction.

[0223] In order for the air introduced into the main body 10 through the air inlet hole 1 to smoothly flow toward 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 inlet hole 1 .

[0224] In addition, in order to allow the air discharged from the rear fan assembly 100 and the corner fan assembly 200 to smoothly flow to the upper space 10i, the rear fan assembly 100 and the corner fan assembly 200 are disposed at a lower height than the upper space 10i.

[0225] When the rear fan assembly 100 and the corner fan assembly 200 are disposed above the upper space 10i, a problem may occur in which a 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.

[0226] Taking this situation into consideration, in the present embodiment, the rear fan assembly 100 and the angular fan assembly 200 are arranged at positions such that the rear fan assembly 100 and the angular fan assembly 200 can be appropriately spaced apart from the air intake hole 1 and the rear fan assembly 100 and the angular fan assembly 200 can be appropriately spaced apart from the upper space 10i.

[0227] Therefore, the flow of air from the air inlet hole 1 to the rear fan assembly 100 and the corner fan assembly 200 and the flow of air from the rear fan assembly 100 and the corner fan assembly 200 to the upper space 10i can be smoothly performed.

[0228] In addition, the corner fan assembly 200 can be disposed at a position closer to the air intake hole 1 than the exhaust holes 2, 3, and 4. Therefore, the second suction hole 212 of the corner fan assembly 200 can be disposed very close to the air intake hole 1. As a result, the suction performance of the corner fan assembly 200, which has a relatively small size and low output, can be effectively improved compared to the rear fan assembly 100.

[0229] [One example of a flow path defining member]

[0230] Figure 10 It shows that Figure 6 A rear perspective view of the cooking appliance is shown with its flow path defining member separated. Figure 11 It is a rear perspective view showing a cooking appliance to which another example of a flow path defining member is applied. Figure 12 It shows that Figure 11 A rear perspective view of the cooking appliance with the flow path defining member separated is shown, and Figure 13 2 is a rear view illustrating a state of air flow in the cooking appliance according to the first embodiment of the present disclosure.

[0231] Reference 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 exhausted from the blowers 100, 200.

[0232] 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 and the upper space 10i to 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 toward the exhaust holes 2, 3, and 4.

[0233] In one example, the exhaust flow path A may be provided in the rear space 10f. The inlet of the exhaust flow path A may open toward the blowers 100 and 200. For example, the inlet of the exhaust flow path A may open 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 open toward the upper space 10i.

[0234] The exhaust flow path A may be formed inside the cooking appliance and may constitute a flow path for guiding airflow 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 airflow from the second suction hole 214 of the corner fan assembly 200 to the upper space 10i.

[0235] In one example, at least a portion of the exhaust flow path A may be defined by the first flow path plate 31. The first flow path plate 31 may constitute a wall that blocks the first suction hole 112 from the first discharge hole 114 of the rear fan assembly 100.

[0236] The first flow path plate 31 may be disposed in the rear space 10f and may be disposed above the rear fan assembly 100. That is, the first flow path plate 31 may constitute a wall blocking the first suction hole 112 and the first discharge hole 114 so that the wall is located above the rear fan assembly 100.

[0237] According to this embodiment, rear fan assembly 100 and corner spaces 10g and 10h can be arranged laterally within rear space 10f. In rear space 10f, first suction holes 112 can be provided on both lateral sides of rear fan assembly 100. First exhaust hole 114 is provided between a pair of first suction holes 112 spaced a predetermined distance apart in the lateral direction and formed on the upper surface of rear fan assembly 100.

[0238] When the first suction hole 112 located closer to the corners 10g, 10h of 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 from the right first suction hole 112. The first flow path plate 31 may 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.

[0239] Hereinafter, a direction toward the electronic / electrical component rooms 10a, 10c, and 10d along a lateral direction around the lateral center of the cooking appliance will be referred to as a left direction, and a direction toward the side space 10e located on the opposite side thereof will be referred to as a right direction.

[0240] The first flow path plate 31 may constitute a vertical wall extending upward from the upper surface of the rear fan assembly 100 formed with the first exhaust hole 114 toward the upper space 10i. The first flow path plate 31 may define a right boundary of the exhaust flow path A.

[0241] The cooking appliance of this embodiment may further include an extension plate 18. The extension plate 18 may be configured to block the upper space 10i and the rear space 10f.

[0242] At least a portion of the extension plate 18 may 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") may be vertically disposed between the rear fan assembly 100 and the upper space 10i. Furthermore, the rear partition portion 18b of the extension plate 18 may be disposed in the front-to-rear direction between the rear surface of the cavity 11 and the rear panel 15.

[0243] The rear partition portion 18b of the extension plate 18 provided as above covers a portion of the rear space 10f while being provided at a position higher than that of the rear fan assembly 100, and blocks a portion of the rear space 10f from the upper space 10i.

[0244] In this embodiment, a case is shown where the right area of the rear space 10 f and the upper space 10 i are blocked from each other via the extension plate 18 .

[0245] The extension plate 18 and the rear fan assembly 100 are arranged vertically spaced apart, thereby forming a transverse flow path between the extension plate 18 and the rear fan assembly 100. The transverse passage thus formed can connect the right side area of the rear space 10f covered by the extension plate 18 with the area above the rear fan assembly 100 that defines the exhaust flow path A.

[0246] The first flow path plate 31 may constitute 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 may constitute 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 portion of the first flow path plate 31 may protrude upward beyond the extension plate 18.

[0247] As described above, the first flow path plate 31 connected to the extension plate 18 may constitute a vertical wall that blocks the transverse passage defined between the rear fan assembly 100 and the extension plate 18. That is, the first flow path plate 31 may constitute a wall that blocks the flow of air between the right area of the rear space 10f and the exhaust flow path A, such that the wall is located in the rear space 10f.

[0248] The flow path defining member 30 may further include a second flow path plate 32. The second flow path plate 32 may constitute a wall that blocks the first suction hole 112 and the first discharge hole 114 of the rear fan assembly 100 from each other.

[0249] The second flow path plate 32 may be disposed on the left side of the rear fan assembly 100. Therefore, the rear fan assembly 100 may be disposed between the first flow path plate 31 and the second flow path plate 32 in the lateral direction.

[0250] In the lateral direction, the second flow path plate 32 may be provided between the rear fan assembly 100 and the corner fan assembly 200. The second flow path plate 32 may constitute a wall that blocks the first suction hole 112 and the first discharge hole 114 from each other, and simultaneously constitute a wall that blocks the second suction hole 214 of the corner fan assembly 200 from the first suction hole 112 of the rear fan assembly 100 from each other.

[0251] In the corner fan assembly 200, the second suction hole 212 is arranged toward the air inlet hole 1, that is, toward the bottom. The second suction hole 214 can be arranged to face the rear fan assembly 100, that is, laterally, more specifically, toward the right side, and can be connected to the exhaust flow path A.

[0252] The second flow path plate 32 may be provided 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 provided 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 may be formed as an inclined surface in which the vertical level changes along the lateral direction.

[0253] According to this embodiment, the second suction hole 214 may be disposed to face the first suction hole 112, and the first suction hole 112 is disposed to face the angle fan assembly 200. The vertical height of the first discharge hole 114 may be higher than the vertical height of the first suction hole 112, and may be higher than the vertical height of the second suction hole 214.

[0254] In one example, the second flow path plate 32 may form an inclined surface extending laterally from the lower side of the second suction hole 214 toward the upper side of the first suction hole 112. For example, the second flow path plate 32 may extend from an end of the second flow path plate adjacent to the corner fan assembly 200 in the lateral direction and extend laterally upwardly and obliquely toward the rear fan assembly 100.

[0255] One end of the second flow path plate 32 in the lateral direction may be disposed below the second suction hole 214. For example, the left end of the second flow path plate 32 may be disposed at a vertical height lower than that of the second suction hole 214.

[0256] In addition, the other end of the second flow path plate 32 in the transverse direction may be disposed above the first suction hole 112. For example, the vertical height of the right end of the second flow path plate 32 may be higher than the vertical height of the first suction hole 112.

[0257] The second flow path plate 32 may form 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. In other words, the second flow path plate 32 may form an inclined wall while being disposed between the rear fan assembly 100 and the corner fan assembly 200, and the wall may 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.

[0258] 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 .

[0259] That is, the second flow path plate 32 may constitute a wall that blocks air from flowing from the first discharge hole 114 and the second suction hole 214 toward the first suction hole 112 such that the wall is located between the rear fan assembly 100 and the corner fan assembly 200 .

[0260] According to this embodiment, the exhaust flow path A may be formed on the left side of the first flow path plate 31 and on the upper side of the second flow path plate 32. The air intake hole 1 may be provided below the exhaust flow path A. In addition, in the vertical direction, the first suction hole 112 and the second suction hole 212 may 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 may be provided between the exhaust flow path A and the upper space 10i.

[0261] The first discharge hole 114 and the second suction hole 214 may be connected to the exhaust flow path A. The first discharge hole 114 may be disposed to face upward and connected to the exhaust flow path A. The second suction hole 214 may be disposed to face laterally and connected to the exhaust flow path A.

[0262] In addition, the second flow path plate 32 may define a flow path for guiding air to the first suction hole 112 .

[0263] In one example, the second flow path plate 32 is positioned above the air intake hole 1 and can be positioned to the left of and above the first suction hole 112. The second flow path plate 32 defines the left and top boundaries of the flow path connecting the air intake hole 1 and the first suction hole 112. Due to the second flow path plate 32 positioned as described above, air can be efficiently introduced from the left side of the rear fan assembly 100 into the first suction hole 112.

[0264] In one example, the flow path defining member 30 may further include a fastening plate 33. The fastening plate 33 may be installed at the rear fan assembly 100.

[0265] In one example, the fastening plate 33 may be configured such that the first exhaust hole 114 opens upward, and may be coupled to the upper surface of the rear fan assembly 100. The fastening plate 33 may be disposed above the first suction hole 112. The vertical height of the fastening plate 33 may be higher than the vertical height of each of the second suction hole 212 and the second suction hole 214.

[0266] According to this embodiment, the first flow path plate 31 may be provided in a form extending upward from the fastening plate 33. In addition, 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.

[0267] 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 .

[0268] In addition, a fastening plate 33 may be provided 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.

[0269] In the flow path defining member 30 set in this manner, the first flow path plate 31 and the second flow path plate 32 do not need to be separately connected 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 mounted to the fastening plate 33 connected to the rear fan assembly 100.

[0270] The fastening plate 33 may have a discharge hole (reference numeral omitted) defined therein, through which the first discharge hole 114 may be exposed to the upper side of the fastening plate 33 , ie, inside the exhaust flow path A.

[0271] In addition, the cooking appliance of the present embodiment may further include a support member 40. The support member 40 is configured to support the corner fan assembly 200. At least a portion of the support member 40 may be disposed in the corner spaces 10g and 10h.

[0272] In one example, the support member 40 may include a transverse support member 41. The transverse support member 41 may be provided at a transverse side of the angular fan assembly 200. The transverse support member 41 may constitute a side surface of the support member 40, more specifically, a right side surface of the support member 40.

[0273] Transverse support members 41 are provided on the lateral sides of corner fan assembly 200 and form vertical walls covering corner fan assembly 200. For example, transverse support members 41 may form vertical planes perpendicular to the transverse axis. Transverse support members 41 may form walls in rear space 10a that block corner fan assembly 200 and rear fan assembly 100 from each other.

[0274] The transverse support member 41 may be disposed between the angular fan assembly 200 and the second flow path plate 32. The transverse support member 41 may define a left boundary of the exhaust flow path A.

[0275] A discharge hole (reference numeral omitted) may be formed in the lateral support member 41 , and the second suction hole 214 may be exposed to the right side of the lateral support member 41 , that is, inside the exhaust flow path A, through the discharge hole.

[0276] The cooking appliance of this embodiment may further include connecting flow path defining members 37 and 38. These connecting flow path defining members 37 and 38 may be disposed above the angular fan assembly 200. These connecting flow path defining members 37 and 38 may partition the rear space 10f, thereby separating a portion of the area surrounding the support member 40 in the rear space 10f as a connecting flow path 39.

[0277] In one example, the connecting flow path defining members 37 , 38 may include a first partition portion 37 and a second partition portion 38 .

[0278] The first partition portion 37 may constitute a vertical wall provided on a lateral side of the support member 40 so as to be spaced apart from the support member 40 by a predetermined distance. In one example, the first partition portion 37 may constitute a vertical wall provided on a lateral side of the lateral support member 41 so as to be spaced apart from the lateral support member 41 by a predetermined distance. In the left lateral direction, the first partition portion 37 may be provided between the corner fan assembly 200 and the rear fan assembly 100.

[0279] The second partition portion 38 may constitute a wall connecting the transverse support member 41 and the first partition portion 37. In one example, the first partition portion 37 may be provided on the right side of the transverse support member 41 and at a position spaced a predetermined distance from the transverse support member 41. The second partition portion 38 may constitute a wall connecting the lower end of the first partition portion 37 and the transverse support member 41.

[0280] In one example, the second partition portion 38 can be disposed above the second flow path plate 32. The left end of the second partition portion 38 can be coupled to the transverse support member 41. In addition, the left end of the second partition portion 38 can be vertically spaced apart from the left end of the second flow path plate 32, with the second suction hole 214 interposed therebetween.

[0281] In one example, the second partition portion 38 may also form an inclined surface parallel to the second flow path plate 32. The second partition portion 38, together with the lateral support member 41, may define the left boundary of the exhaust flow path A and may guide the air flow discharged from the second suction hole 214 into the exhaust flow path A to the lateral center point of the exhaust flow path A.

[0282] The first partition portion 37 may extend upward from the second partition portion 38. Thus, 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 flowing through the exhaust flow path A toward the upper space 10i.

[0283] 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 can be generated to draw air outside the cooking appliance into the cooking appliance. The suction airflow generated as described above acts on the outside air drawn in through the air intake hole 1 provided at the lower end of the cooking appliance. The outside air (i.e., cooking gas) surrounding the air intake hole 1 can be drawn into the main body 10 through the air intake hole 1 under the suction airflow acting in this manner.

[0284] The cooking gas drawn into the main body 10 may be introduced into the rear space 10f in the space defined in the main body 10. The cooking gas introduced into the rear space 10f may be drawn 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.

[0285] 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 toward the first suction hole 112 provided on the left side of the rear fan assembly 100 may be guided by the second flow path plate 32 .

[0286] The air drawn 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.

[0287] The air discharged from the second discharge hole 214 of the corner fan assembly 200 may flow through the exhaust flow path A, then through the rear space 10i and into the upper space 10f. The exhaust flow path A may constitute an inclined flow path around the second discharge hole 214 extending obliquely rightward from the second discharge hole 214.

[0288] The right upward inclined flow path formed as described 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 described 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.

[0289] 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 to the upper space 10f. In this regard, the exhaust flow path A can guide the airflow so that the air discharged through the first discharge hole 114 can flow toward the upper space 10i without being diffused around it.

[0290] [Another Example of Flow Path Defining Member]

[0291] Reference Figure 11 and Figure 12 , the flow path defining member 35 may further include an extension plate 34. The extension plate 34 may constitute a wall that blocks the first suction hole 112 and the first discharge hole 114 from each other.

[0292] 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.

[0293] In the lateral direction, the rear fan assembly 100 may be disposed between the extension plate 34 and the first flow path plate 31. Furthermore, the extension plate 34 may be disposed in the lateral direction between the rear fan assembly 100 and the corner fan assembly 200. Furthermore, the extension plate 34 may be disposed in the lateral direction between the lateral support 41 and the fastening plate 33, and between the connection flow path defining member 35 and the fastening plate 33.

[0294] The extension plate 34 provided as described above may be provided between the transverse 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. In other words, the extension plate 34 may also constitute a vertical wall between the left and right boundaries of the exhaust flow path A.

[0295] The extension plate 34 can divide the exhaust flow path A into a first exhaust flow path A1 constituting the right side thereof and a second exhaust flow path A2 constituting the left side thereof. The extension plate 34 can define the left boundary of the first exhaust flow path A1 and the right boundary of the second exhaust flow path A2.

[0296] The first exhaust flow path A1 may constitute a passage connecting the first discharge hole 114 and the upper space 10i to each other, so that the passage is defined in the rear space 10f. The second exhaust flow path A2 may constitute a passage connecting the second suction hole 214 and the upper space 10i to each other, so that the passage may be formed in the rear space and isolated from the first exhaust flow path A1.

[0297] In addition, the flow path defining member 35 can 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 can be provided in the form of connecting the first flow path plate 31 and the fastening plate 33 to each other, and the second flow path defining member 35b can be provided in the form of connecting the second flow path defining member 35b and the extension plate 34 to each other.

[0298] The first flow path defining member 35a may be disposed inside the cooking appliance by coupling 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 coupling between the second flow path plate 32a and the transverse support 41.

[0299] As described above, the exhaust flow path A can be divided into the first exhaust flow path A1 and the second exhaust flow path A2 via the flow path defining member 35. Therefore, the air discharged to the rear space 10f by the rear fan assembly 100 and the air discharged to the rear space 10f by the corner fan assembly 200 can flow toward the upper space 10i through separate flow paths, respectively.

[0300] The flow path defining member 35 can divide the exhaust flow path A into the first flow path and the second flow path as described above, thereby suppressing mixing of air discharged from the corner fan assembly 200 and air discharged from the rear fan assembly 100 within the exhaust flow path A.

[0301] [Structure of air intake and exhaust of cooking appliances]

[0302] Figure 14 is a rear perspective view showing a first state of the cooking appliance according to the first embodiment of the present disclosure, and Figure 15 It shows that Figure 14 A diagram showing the air flow conditions in a cooking appliance. Figure 16 is a rear perspective view showing a second state of the cooking appliance according to the first embodiment of the present disclosure, and Figure 17 It shows that Figure 16 A diagram showing the air flow conditions in a cooking appliance. Figure 18 is a rear perspective view showing a third state of the cooking appliance according to the first embodiment of the present disclosure, and Figure 19 It shows that Figure 18 A diagram showing the air flow conditions in a cooking appliance.

[0303] In the following, reference will be made to Figures 13 to 19 A structure for sucking and exhausting air in a cooking apparatus according to the present embodiment is described.

[0304] Reference Figures 13 to 15 The air intake hole 1 may be provided at the lower end of the cooking appliance, and the exhaust hole may be provided at the upper end of the cooking appliance. The first exhaust hole 2 may be provided in the upper surface of the housing 13 and may be provided closer to the rear side of the cooking appliance, and the second exhaust hole 3 may be provided in the upper surface of the housing 13 and may be provided closer to the front side of the cooking appliance. Furthermore, the third exhaust hole 4 may be provided in the rear end of the cooking appliance and may be defined in the rear panel 15.

[0305] The blowers 100 and 200 may include a rear fan assembly 100 and a corner fan assembly 200, and the rear fan assembly 100 may be disposed in the rear space 10f. The corner fan assembly 200 may be disposed in the rear space 10f or the corner spaces 10g and 10h.

[0306] When the rear fan assembly 100 and the corner fan assembly 200 begin operating, a suction airflow is generated to draw air from outside the cooking appliance into the cooking appliance. The suction airflow generated in this manner acts on the outside air through the air intake hole 1 provided at the lower end of the cooking appliance. With this suction airflow, the outside air (i.e., cooking gas) surrounding the air intake hole 1 flows through the air intake hole 1 and is drawn into the main body 10.

[0307] In addition, the cooking gas drawn into the body 10 may be introduced into the rear space 10f through the lower space. For example, the cooking gas introduced into the lower space may be introduced into the rear space 10f and the corner spaces 10g and 10h.

[0308] The cooking gas introduced into the rear space 10f may be sucked into the rear fan assembly 100 through the first suction holes 112 respectively provided at two opposite sides of the rear fan assembly 100. The cooking gas sucked into the rear fan assembly 100 may be discharged upward through the first discharge hole 114 provided at the upper side of the rear fan assembly 100.

[0309] The cooking gas introduced into the corner spaces 10g and 10h may be drawn 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 drawn into the corner fan assembly 200 may be laterally discharged from the corner fan assembly 200 through the second discharge holes 214 provided at the side surface of the corner fan assembly 200.

[0310] The rear space 10f may connect the air intake hole 1 provided below the lower space to the upper space 10i. Furthermore, an exhaust flow path A may be formed in the rear space 10f. The cooking gas exhausted from the rear fan assembly 100 and the corner fan assembly 200 may be directed toward the upper space 10i through the exhaust flow path A.

[0311] When only the first exhaust hole 2 among the exhaust holes 2, 3 and 4 is opened 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.

[0312] In one example, the first exhaust hole 2 may be connected to a pipe (not shown) communicating with the outdoor area. For example, a pipe may be installed on the upper surface of the main body 10, and an inner space of the pipe may be connected to the first exhaust hole 2.

[0313] The first exhaust hole 2 connected to the duct as described above may constitute a passage connecting the upper space 10i to the outside of the cooking appliance. The first exhaust hole 2 may be disposed above the upper space 10i and may be disposed at a position vertically overlapping the rear space 10f.

[0314] That is, the rear fan assembly 100, the rear space 10f and the first exhaust hole 2 may overlap each other in the vertical direction. Preferably, the rear fan assembly 100, the rear space 10f and the first exhaust hole 2 may be aligned with each other in a line along the vertical direction.

[0315] Alternatively, the exhaust passage A may be provided between the blowers 100, 200 and the first exhaust hole 2 within the rear space 10f. The inlet of the exhaust passage A may open toward the blowers 100, 200, and the outlet of the exhaust passage A may open toward the upper space 10i. Alternatively, the first exhaust hole 2 may be provided in an area vertically overlapping with the outlet of the exhaust passage A.

[0316] Therefore, the air flow generated by the operation of the rear fan assembly 100 may have the same linear direction as the alignment direction of the rear fan assembly 100 , the rear space 10 f , and the first exhaust hole 2 .

[0317] As described above, when air flows in a straight line, the resistance to air flow is reduced, so that the air flow can be carried out more smoothly. Therefore, the air suction and exhaust performance of the rear fan assembly 100 can be improved, thereby correspondingly improving the cooking gas removal performance of the cooking appliance.

[0318] In one example, the cooking appliance of this embodiment can discharge the cooking gas drawn into the cooking appliance into the indoor space. Figure 16 and Figure 17 In this regard, the cooking appliance may be in a state (hereinafter referred to as "the second state of the cooking appliance") in which only the second exhaust hole 3 of the exhaust holes 2, 3, and 4 is open and the first exhaust hole 2 and the third exhaust hole 4 thereof are closed.

[0319] In the second state of the cooking appliance, a passage for discharging cooking gas drawn into the interior of the cooking appliance into the indoor space may be formed by the second exhaust hole 3. That is, the cooking gas introduced into the rear space 10f through the air inlet hole 1 may flow through the upper space 10i and then be discharged into the indoor space through the second exhaust hole 3.

[0320] 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.

[0321] In another example, a 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, 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.

[0322] like Figure 18 and Figure 19 The cooking appliance of the present embodiment shown can discharge the cooking gas drawn into the cooking appliance to the outside through the third exhaust hole 4 .

[0323] In this regard, the cooking appliance may be in a state in which only the third exhaust hole 4 among the exhaust holes 2, 3 and 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").

[0324] In one example, the third exhaust hole 4 can be connected to a pipe or conduit (not shown) embedded in the wall surface on which the cooking appliance is installed. For example, a pipe or conduit can be coupled to the back plate 15, and the inner space of the pipe or conduit can be connected to the third exhaust hole 4.

[0325] The third exhaust hole 4, which is connected to the pipe or duct, is located closest to the blowers 100 and 200. Therefore, in the third state of the cooking appliance, the distance between the blowers 100 and 200 and the exhaust holes 2, 3, and 4 can be the shortest. Furthermore, since the third exhaust hole 4 is defined in the rear surface of the cooking appliance that faces the wall, the third exhaust hole 4 and the pipe or duct are not exposed to the outside.

[0326] 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.

[0327] As described above, the cooking appliance according to the present embodiment adopts a structure in which the blowers 100 and 200 are disposed in the rear space 10f, so that the flow of air involved in drawing cooking gas and discharging the cooking gas through the first exhaust hole 2 is performed in a straight direction, thereby minimizing airflow loss in the cooking appliance and providing more improved cooking gas removal performance.

[0328] In addition, in the cooking appliance according to the present embodiment, a filter installation space may be effectively ensured in the upper space 10i, thereby maintaining a compact size and smoothly filtering and discharging cooking gas to the indoor space.

[0329] In one example, as described above, the space inside the 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 the side space 10e or the upper space 10i.

[0330] Typically, the lateral length of the side space 10e where no electronic / electrical component room is provided is set shorter than the longitudinal length of the rear space 10f. That is, the side space 10e may only provide a space narrower than the rear space 10f.

[0331] Depending on the type of cooking appliance, various devices may be provided in the rear space 10f. For example, in a cooking appliance providing a convection function, a convection module may be provided in the rear space 10f.

[0332] On the other hand, it is rare to install components in the side spaces 10e that do not constitute the electronic / electrical component compartments 10b, 10c, and 10d. Therefore, the lateral width of the lateral spaces 10e does not need to be unnecessarily increased. Unnecessarily increasing the lateral length of the side spaces 10e increases the overall size of the cooker, regardless of whether the performance of the cooker is improved.

[0333] In consideration of this fact, the side space 10e is formed to provide a space narrower than the rear space 10f.

[0334] To reduce costs, different types of cooking utensils with the same cooking chamber volume generally use the same size body 10. For example, a cooking utensils providing both high frequency and convection functions can be manufactured using the same size body 10 as a cooking utensils providing only high frequency functions.

[0335] Therefore, the body 10 of the present embodiment may include the rear space 10f providing a space suitable for accommodating the convection module therein, and the side space 10e may be formed in a form providing only a space narrower than the rear space 10f.

[0336] Taking this into consideration, the blowers 100 and 200 of the present embodiment can be disposed in the rear space 10f, which provides a more ample space than the side space 10e. As described above, the blowers 100 and 200 are disposed in the rear space 10f, so that the air flow loss inside the cooking appliance as described above can be reduced, and a larger fan assembly with high performance can be applied to the blowers 100 and 200.

[0337] That is, the cooking appliance of the present embodiment including the blowers 100 and 200 disposed in the rear space 10 f can provide improved cooking gas removal performance while suppressing an increase in size of the cooking appliance using the main body 10 of a commonly used size.

[0338] [Supporting member]

[0339] Figure 20 is an enlarged view showing the angular fan assembly and its surroundings in an enlarged manner, Figure 21 It is shown from Figure 20 A rear perspective view of the cooking appliance is shown with the support member removed. Figure 22 is a rear perspective view showing a portion of a cooking appliance to which another example of a support member is applied, and Figure 23 It shows that Figure 22A rear perspective view of the cooking appliance is shown with the support member removed.

[0340] Reference Figure 6 、 Figure 20 and Figure 21 The cooking appliance of the present embodiment may include a support member 40. The support member 40 may support the angle fan assembly 200 so that the air flow discharged from the second suction hole 214 may be guided toward the rear space 10f.

[0341] At least a portion of the support member 40 may constitute a wall that blocks the side space 10e and the rear space 10f from each other. That is, at least a portion of the support member 40 may constitute a wall that blocks the corner fan assembly 200 and the rear fan assembly 100 in the rear space 10f from each other.

[0342] Support member 40 may form a wall that divides rear space 10f into two areas arranged in a transverse direction. In one example, support member 40 may divide the portion of rear space 10f adjacent to side space 10e into corner spaces 10g and 10h. Furthermore, at least a portion of support member 40 may form a wall covering corner fan assembly 200, while being disposed on the side of corner fan assembly 200. Such a wall may be formed by transverse support members 41.

[0343] The second suction hole 214 may be provided at a side of the corner fan assembly 200 and may face the support member 40, more specifically, the transverse support 41. In addition, a discharge hole 41a may be formed in the transverse 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 transverse support 41.

[0344] The lateral support 41 may be coupled to the angular fan assembly 200. That is, the angular fan assembly 200 may be coupled to the lateral support 41 from the side and may be supported by the support member 40.

[0345] The support member 40 may include a front support piece 42. The front support piece 42 constitutes a front surface of the support member 40 and is disposed in front of the corner fan assembly 200.

[0346] The front support member 42 can constitute a vertical wall covering the angular fan assembly 200 while being disposed in front of the angular fan assembly 200. For example, the front support member 42 can constitute a vertical plane orthogonal to the front-rear axis. The front support member 42 can be disposed in the cooling fan 6 (see FIG. Figure 25 ) and the angular fan assembly 200, and a wall that blocks the cooling fan 6 and the angular fan assembly 200 from each other can be formed so that the wall is located in the electronic / electrical component rooms 10b, 10c and 10d.

[0347] The front support member 42 may be connected to the lateral support member 41 at a side of the lateral support member 41. In one example, the right end of the front support member 42 may be connected to the front end of the lateral support member 41. For example, the front support member 42 and the lateral support member 41 may be coupled to each other to form an "L" shape.

[0348] The front support member 42 connected to the lateral support member 41 can support the lateral support member 41 while being disposed in front of the lateral support member 41. The front support member 42 can function as a shielding wall for shielding the cooling fan 6 and the angular fan assembly 200, and function as a supporting wall for supporting the lateral support member 41 for supporting the angular fan assembly 200.

[0349] Furthermore, the front support member 42 may include a support surface forming 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 disposed 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 member 42. In this embodiment, a high-voltage capacitor is shown mounted on the support surface of the front support member 42.

[0350] In addition, the support member 40 may further include an upper support 43. The upper support 43 constitutes an upper surface of the support member 40 and is disposed on an upper side of the corner fan assembly 200. In one example, the upper support 43 may be disposed in the corner spaces 10g and 10h.

[0351] The upper support 43 may be disposed above the lateral support 41 and the front support 42 and may be vertically connected to at least one of the lateral support 41 and the front support 42. In this embodiment, the upper support 43 is shown to be connected to both the lateral support 41 and the front support 42.

[0352] On the other hand, the front end of the upper support member 43 can be connected to the upper end of the front support member 42, and the right end of the upper support member 43 can be connected to the upper end of the lateral support member 41. Due to the upper support member 43, the three directional surfaces of the support member 40 are connected to each other, thereby improving the structural stability of the support member 40.

[0353] Furthermore, the upper support 43 may include a support surface for forming a horizontal surface for coupling with electronic / electrical components. In this embodiment, a noise filter connected to the angular fan assembly is shown mounted on the support surface of the upper support 43.

[0354] The support member 40 including the lateral support member 41, the front support member 42 and the upper support member 43 as described above can provide a shielding wall that blocks the cooling fan 6 and the angular fan assembly 200 from each other, and can also provide a support wall for stably mounting electronic / electrical components and the angular fan assembly 200.

[0355] In one example, the support member 40 may be provided in a form in which the lateral support 41, the front support 42, and the upper support 43 are integrally formed with each other. The support member 40 may facilitate assembly and installation of electronic / electrical components and management of components, and may have excellent structural stability.

[0356] As another example, Figure 22 and Figure 23 As shown, the lateral support member, the front support member and the upper support member can be provided separately.

[0357] 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.

[0358] For example, the first support plate 45a can constitute a lateral support member, the second support plate 45b can constitute a front support member, and the third support plate 45c can constitute an upper support member. The first support plate 45a, the second support plate 45b, and the third support plate 45c provided as separate plates can be coupled to each other to form the support member 40.

[0359] In one example, the first support plate 45a may be provided in a form including both the lateral support and the connecting flow path defining members 37 and 38. That is, in the first support plate 45a, the lateral support and the connecting flow path defining members 37 and 38 may be formed integrally with each other.

[0360] In addition, the through hole 41 b may be defined in the first support plate 45 a , or may be defined in the third support plate 45 c .

[0361] [Structure of the electronic / electrical components room]

[0362] Figure 24 is a diagram showing a state in which external air is introduced into the electronic / electrical component room through a cold air inlet, Figures 25 to 27 is a diagram showing the flow state of air introduced into the electronic / electrical component room, Figure 28 1 is a diagram showing the flow state of air introduced from the upper corner space into the lower corner space through the connecting flow path.

[0363] Reference Figure 24 and Figure 25, the main body 10 may have a cool air inlet 5 defined therein. The cool air inlet 5 may be provided in an upper surface of the main body 10 in which the first exhaust hole 2 and the second exhaust hole 3 are defined.

[0364] In one example, the cool air inlet 5 may be formed to vertically penetrate the upper surface of the housing 13. The cool 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. External air may be introduced into the electronic / electrical component chambers 10b, 10c, and 10d through the cool air inlet 5.

[0365] Reference 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, more specifically, in the electronic / electrical component chambers 10b, 10c, and 10d.

[0366] In one example, the partition plate 50 may also form a horizontal plane perpendicular to the vertical axis. The partition plate 50 may vertically divide 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, and 10d may be divided into the lower electronic / electrical component chamber 10b below the partition plate 50 and the upper electronic / electrical component chamber 10c above the partition plate 50.

[0367] In one example, among the electronic / electrical component chambers 10b, 10c, and 10d, the lower electronic / electrical component chamber 10b can occupy a space that is much wider 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 electronic / electrical components, including magnetrons, high-voltage transformers, high-voltage capacitors, etc., can be primarily located in the lower electronic / electrical component chamber 10b.

[0368] The cooking appliance of this embodiment may further include a cooling fan 6. The cooling fan 6 is configured to draw outside air into the electronic / electrical component compartments 10b, 10c, and 10d through the cool air intake holes 5. In one example, the cooling fan 6, along with most of the electronic / electrical components, may be located in the lower electronic / electrical component compartment 10b.

[0369] The blowers 100 and 200 may be disposed behind the cooling fan 6. The support member 40, more specifically, the front support 42 may be disposed between the cooling fan 6 and the corner fan assembly 200.

[0370] The cooling fan 6 may generate an air flow for introducing external air into the main body 10 through the cool air inlet 5 .

[0371] When the cooling fan 6 operates, external air may be introduced into the upper electronic / electrical component chamber 10c through the cool air inlet 5. The air introduced into the upper electronic / electrical component chamber 10c may flow through the partition plate 50 and be introduced into the lower electronic / electrical component chamber 10b.

[0372] To this end, the partition plate 50 may have through-holes 52 and 54 defined therein. The through-holes 52 and 54 may constitute 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 may be formed to extend through the partition plate 50 in the vertical direction.

[0373] The air introduced into the upper electronic / electrical component chamber 10c through the cool 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.

[0374] In addition, a portion of the air introduced into the lower electronic / electrical component chamber 10b may be introduced into the cooking chamber 10a (see Figure 2 To this end, the cavity 11 may have a side hole 11a. The side hole 11a may constitute 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.

[0375] In this embodiment, side hole 11a is provided in lower electronic / electrical component chamber 10b. In one example, side hole 11a is formed to extend transversely through cavity 11, thereby forming a passage connecting lower electronic / electrical component chamber 10b and cooking chamber 10a in cavity 11. Side hole 11a may be provided in front of support member 40.

[0376] The cooking appliance of this embodiment may further include a baffle 55. The baffle 55 may partition the upper electronic / electrical component chamber 10c in the front-rear direction so that the front area of the upper electronic / electrical component chamber 10d is separated into an air intake chamber 10d.

[0377] In one example, the baffle 55 may constitute a vertical wall surface orthogonal to the front-rear axis.The baffle 55 may be disposed above the partition plate 50 and may be coupled to an upper surface of the partition plate 50.

[0378] Due to the baffle 55 provided as above, the area between the front plate 12 of the upper electric / electronic component chamber 10 c and the baffle 55 can be separated as the air intake chamber 10 d .

[0379] A plurality of through-holes 52 and 54 may be defined in the partition plate 50. In one example, the partition plate 50 may have a first through-hole 52 and a second through-hole 54. The first through-hole 52 and the second through-hole 54 may be spaced apart from each other in the front-to-rear direction with a baffle 55 interposed therebetween.

[0380] The first through hole 52 may constitute a passage connecting the air intake chamber 10a and the lower electronic / electrical component chamber 10b to each other. The first through hole 52 may be provided in front of the baffle 55 and the cooling fan 6 and may be formed to penetrate the partition plate 50 in a vertical direction.

[0381] The second through hole 54 can constitute a passage connecting the upper electronic / electrical component chamber 10c and the lower electronic / electrical component chamber 10b to each other, and the second through hole 54 is provided at the rear of the air intake chamber 10a. The second through hole 54 can be provided at the rear of the baffle 55 and the cooling fan 6 and can be formed to pass through the partition plate 50 in the vertical direction.

[0382] According to the present 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 separate 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.

[0383] The lower corner space 10h may be disposed below the upper support member 43. An upper boundary surface of the lower corner space 10h may be defined by the upper support member 43, a front boundary surface of the lower corner space 10h may be defined by the front support member 42, and a 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 disposed in the lower corner space 10h.

[0384] The upper corner space 10g may be provided above the upper support 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.

[0385] At least one of the electronic / electrical components disposed in the upper electronic / electrical component chamber 10c may be disposed in the upper support 43. In one example, a noise filter connected to the corner fan assembly 200 may be disposed in the upper corner space 10g, and the noise filter may be mounted on the upper surface of the upper support 43.

[0386] The air introduced into the lower electronic / electrical component chamber 10b by the cooling fan 6 can flow into the upper electronic / electrical component chamber 10c through the second through-holes 54. Thus, the air introduced into the upper electronic / electrical component chamber 10c can cool the electronic / electrical components mounted in the upper support member 43 while flowing through the upper corner space 10g.

[0387] 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 constitute a passage through which air introduced into the lower electronic / electrical component chamber 10b by the cooling fan 6 flows through the upper electronic / electrical component chamber 10c toward the blowers 100 and 200. For example, the connecting flow path 39 can constitute a path through which 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.

[0388] In addition, a through hole 41b may be defined in the lateral support member 41. The through hole 41b is configured to open a space surrounded by the lateral support member 41 and the front support member 42, that is, the lower corner space 10h, in the lateral direction.

[0389] The connecting flow path 39 can constitute a passage connecting the through-hole 41b and the upper electronic / electrical component chamber 10c, more specifically, a passage connecting the through-hole 41b and the upper corner space 10g. The connecting flow path 39 can also be arranged on the lateral side of the corner spaces 10g and 10h to communicate with the upper corner space 10g and the lower corner space 10h. The connecting flow path 39 and the lower corner space 10h can communicate with each other through the through-hole 41b.

[0390] As described above, the connecting flow path 39 may 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 may constitute a vertical wall provided on a lateral side of the lateral support member 41 so as to be spaced apart from the lateral support member 41 by a predetermined interval. The second partition portion 38 may be connected to the lateral support member 41 while being provided below the through hole 41b, and constitute a wall connecting the lateral support member 41 and the first partition portion 37 to each other.

[0391] Two opposing side surfaces of the connecting flow path 39 may be defined by the lateral support 41 and the first partition 37. For example, a left side surface of the connecting flow path 39 may be defined by the lateral support 41, and a right side surface of the connecting flow path 39 may be defined by the first partition 37. A bottom surface of the connecting flow path 39 may be defined by the second partition 38.

[0392] The air introduced into the upper electronic / electrical component chamber 10c may 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 may flow into the lower corner space 10h through the through hole 41b and then be sucked into the corner fan assembly 200.

[0393] 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 connecting flow path 39 connecting the lower corner space 10h and the upper corner space 10g. In other words, the suction force of the corner fan assembly 200 can affect the upper corner space 10g, which can act as a force to cause the air flowing into the upper corner space 10g to flow toward the lower corner space 10h.

[0394] Finally, the suction force of the corner fan assembly 200 may serve as a force to guide the air flow introduced into the upper electronic / electrical component chamber 10 c from the lower electronic / electrical component chamber 10 b to the lower corner space 10 h through the connecting flow path 39 .

[0395] Next, the air flow in the electronic / electrical component rooms 10b, 10c, and 10d will be described.

[0396] like Figure 24 As shown, external air can be introduced into the main body 10 through the cool air inlet 5. The air that has flowed through the cool air inlet 5 can be introduced into the air intake chamber 10d, as shown in FIG. Figures 25 to 27 shown.

[0397] The air introduced into the air intake chamber 10d can flow through the partition plate 50 through the first through-hole 52 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 rearward direction by the cooling fan 6. As described above, the air flowing rearward in the lower electronic / electrical component chamber 10b can cool the electronic / electrical components arranged in the lower electronic / electrical component chamber 10b.

[0398] A portion of the air flowing in the lower electronic / electrical component chamber 10b can flow through the cavity 11 and be introduced into the electronic / electrical component chamber through the air inlet hole 1. Another portion of the air flowing in the lower electronic / electrical component chamber 10b can flow through the partition plate 50 through the second through-hole 54 and flow into the upper electronic / electrical component chamber 10c.

[0399] In the upper electronic / electrical component chamber 10c, air can flow toward the connecting flow path 39 under the influence of the suction force of the angular fan assembly 200. For example, Figure 28 As shown, the air introduced into the upper electronic / electrical component chamber 10 c can cool the electronic / electrical components while flowing through the upper corner space 10 g and then flow into the connecting flow path 39 .

[0400] The air flowing into the connecting flow path 39 can flow into the lower corner space 10h through the through hole 41b formed in the horizontal support member 41 and be sucked into the corner fan assembly 200. Figure 13 As shown, the air flowing from the connecting flow path 39 into the lower corner 10h merges with the air flowing into the interior of the main body 10 through the air inlet hole 1, and the merged air is sucked into the interior of the corner fan assembly 200 and discharged to the exhaust flow path A.

[0401] like Figures 24 to 28 As 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 force of the corner fan assembly 200 to be added to the force provided by the cooling fan 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 disposed in the electronic / electrical component chambers 10b, 10c and 10d to be cooled more effectively.

[0402] 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 amount of the corner fan assembly 200, and ultimately helping to effectively increase the exhaust air amount of the corner fan assembly 200.

[0403] In one example, referring to Figures 25 to 27 The cooking appliance of this 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.

[0404] In one example, the flow path dividing plate 16 may also constitute a vertical wall perpendicular to the horizontal axis. The flow path dividing plate 16 may block the upper electronic / electrical component chamber 10c and the upper space 10i from each other, thereby isolating the two spaces from each other. For example, the flow path dividing plate 16 may define the right boundary of the upper electronic / electrical component chamber 10c and the left boundary of the upper space 10i.

[0405] In addition, the cooking appliance of the present embodiment may include a waveguide 17. The waveguide 17 is configured to transmit microwaves generated from magnetrons installed in the electronic / electrical component chambers 10b, 10c, and 10d to the cooking chamber 10a.

[0406] The waveguide tube 17 may be provided 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 portion of the waveguide tube 17 may be mounted on the upper surface of the partition plate 50, and the remaining portion of the waveguide tube 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.

[0407] A space is formed inside the waveguide 17. An inlet of the waveguide 17 connected to the space can be connected to the magnetron, and an outlet of the waveguide 17 connected to the space can be connected to the cooking chamber 10a. Microwaves introduced into the waveguide 17 through the inlet can be introduced into the cooking chamber 10a through the outlet of the waveguide 17.

[0408] The outlet of the waveguide 17 can be connected to the cooking chamber 10a while being defined at the upper surface of the cavity 11. Therefore, microwaves transmitted from the magnetron through the waveguide 17 can flow through 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 can be defined in the upper surface of the cavity 11 and can be positioned approximately at the lateral center of the cavity 11.

[0409] 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 located in the rear space 10f rather than the upper space 10i, and the vertical length of the upper space 10i can be reduced accordingly, the reduction in the length of the upper space 10i is inevitably less than the reduction in the overall length of the cooking appliance. Therefore, it is difficult to avoid a reduction in the length of the cooking chamber 10a due to the reduction in the length of the cooking appliance.

[0410] In this case, the shape of the cooking chamber 10a is flat and horizontally elongated compared to a typical cooking chamber of a cooking appliance. In a cooking appliance having a cooking chamber 10a of such a shape, when microwaves are introduced into the cooking chamber 10a through the side surface of the cavity 11, it is difficult to uniformly supply the microwaves to the entire cooking chamber 10a.

[0411] Taking this into consideration, in the present embodiment, the waveguide 17 is installed on the upper surface of the cavity 11, and microwaves can 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, microwaves can be supplied through the upper surface of the cooking chamber 10a, and thus, microwaves can be uniformly supplied to the entire cooking chamber 10a.

[0412] [One example of a shield member]

[0413] Reference Figures 25 to 27The cooking appliance of this 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, while being disposed on top of or below the partition plate 50. The shielding member 60 may be disposed to be spaced apart from the partition plate 50 or the first through-hole 52 by a predetermined distance in the vertical direction.

[0414] In this 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 housing 13 and the partition plate 50. In one example, the shielding member 60 may be disposed in the upper electronic / electrical component chamber 10c, more specifically, in the air intake chamber 10d.

[0415] In the vertical direction, the shielding member 60 may be provided between the first through hole 52 and the cool air inlet 5. The shielding member 60 may be configured so that one of the first through hole 52 and the cool air inlet 5 is completely shielded by the shielding member 60 in a plan view of the body 10.

[0416] 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 constitute a horizontal wall that completely shields the first through-hole 52 while being located on top of the first through-hole 52.

[0417] The shielding member 60 may be mounted on the baffle 55. The shielding member 60 may be mounted on the baffle 55 so as to be coupled to the front surface of the baffle 55 and to protrude in the forward direction from the baffle 55. In this regard, the shielding member 60 may be coupled to the baffle 55 at a position spaced upwardly from the upper surface of the partition plate 50 by a predetermined distance.

[0418] 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 air can flow smoothly through the first through-hole 52. That is, the shielding member 60 shields the first through-hole 52 so that the first through-hole 52 is invisible to a position on top of the shielding member 60, while 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 or absence of the shielding member 60.

[0419] The shielding member 60 can block the first through hole 52 and the cold air inlet 5 from each other. The shielding member 60 can be used to shield the flame rising upward 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 is not exposed to the outside of the cooking appliance through the cold air inlet 5.

[0420] Most high-voltage electronic / electrical components, such as a high-voltage transformer and a high-voltage capacitor, are placed in the lower electronic / electrical component chamber 10 b. As described above, the high-voltage electronic / electrical components placed in the lower electronic / electrical component chamber 10 b pose a risk of catching fire in the lower electronic / electrical component chamber 10 b.

[0421] When a fire occurs in the lower electronic / electrical component chamber 10b, the generated flame is exposed to the outside of the cooking utensil. Therefore, the flame exposed to the outside of the cooking utensil is transferred to the surrounding environment around the cooking utensil, thereby increasing the risk of fire spreading.

[0422] In the cooking appliance, a first through hole 52 is provided above the lower electronic / electrical component chamber 10b to form a passage for air in the air intake chamber 10d to flow into the lower electronic / electrical component chamber 10b. Furthermore, a cold air inlet 5 is provided above the first through hole 52 to form a passage for introducing external air into the air intake chamber 10d.

[0423] Therefore, the flame generated in the lower electronic / electrical component chamber 10b can rise upward into the air intake hole 1 through the first through-hole 52, and can rise upward to the upper side of the main body 10 through the cold air inlet 5 in the air intake chamber 10d, and be exposed to the outside of the cooking appliance. To prevent this, it is necessary to block the flame generated in the lower electronic / electrical component chamber 10b inside the cooking appliance to prevent the flame from being exposed to the outside of the cooking appliance.

[0424] Taking this into consideration, in the present embodiment, a shielding member 60 provided in the air intake chamber 10d is configured to block the first through hole 52 and the cold air intake hole 5 from each other. The shielding member 60 can block the flame generated in the lower electronic / electrical component chamber 10b in the air intake chamber 10d, so that the flame generated in the lower electronic / electrical component chamber 10b is not exposed to the outside of the cooking appliance.

[0425] 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 10 b while significantly reducing the risk of fire spreading due to flames generated inside the cooking appliance.

[0426] [Another Example of Shielding Member]

[0427] Figure 29 It is a rear perspective view showing a portion of a cooking appliance to which another example of a shielding member is applied.

[0428] like Figure 29 As shown, the baffle 60 (see Figure 27) is not provided in the upper electronic / electrical component chamber 10c, and therefore, the upper electronic / electrical component chamber 10c may not be partitioned in the front-to-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.

[0429] The horizontal surface portion 66 constitutes an upper surface of the shielding member 65 and is configured to shield the first through-hole 52 when located on 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.

[0430] 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 apart from the upper surface of the partition plate 50.

[0431] 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.

[0432] The ventilation holes 67a may be defined in at least one vertical surface portion among the plurality of vertical surface portions 67. In the present embodiment, it is illustrated that the ventilation holes 67a are defined in the respective vertical surface portions 67, respectively.

[0433] The ventilation hole 67a may be formed to extend in the horizontal direction through the vertical surface portion 67. The ventilation hole 67a may constitute a passage for communicating the outside of the shielding member 65 with the inner space of the shielding member 65. Figure 24 ) The air introduced into the upper electronic / electrical component chamber 10c can be introduced into the shielding member 65 from the outside of the shielding member 65 through the ventilation holes 67a, and then introduced into the lower electronic / electrical component chamber 10b through the first through-holes 52.

[0434] The shield member 65 provided as above can provide an effect of significantly reducing the risk of fire spreading due to flames generated inside the cooking appliance, and can be effectively installed in the upper electronic / electrical component chamber 10c even if the baffle 55 is not installed.

[0435] [Structure of the upper space]

[0436] Figure 30is a rear perspective view showing an air intake state and an air exhaust state of the cooking appliance according to the first embodiment of the present disclosure, and Figure 31 It shows that Figure 30 A rear perspective view showing the air flow inside the cooking appliance. Figure 32 Yes Figure 30 An enlarged plan view of the surrounding environment around the common exhaust vent is shown, Figure 33 It is an enlarged view of the exhaust duct and its surrounding environment.

[0437] Reference Figure 14 、 Figure 30 and Figure 32 , circulating air discharge hole 11b (see Figure 34 ) may be provided inside the 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 through the upper surface of the cavity 11 in a vertical direction.

[0438] According to this 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, 200 and the air flowing into the upper space 10i from the circulating air discharge hole 11b.

[0439] In one example, the circulating air discharge hole 11b may be provided closer to the right end around the transverse center of the cavity 11. For example, the circulating air discharge hole 11b may be provided at a position overlapping at least a portion of the common exhaust hole 3a in the front-rear direction.

[0440] According to this embodiment, multiple second exhaust holes 3 and the cold air inlet 5 can be arranged in a horizontal direction. In one example, at least one of the multiple second exhaust holes 3 located farthest from the cold air inlet 5 can be set as a shared exhaust hole 3a. For example, the cold air inlet 5 can be located to the left of the second exhaust hole 3, and the rightmost second exhaust hole of the multiple second exhaust holes 3 can be set as the shared exhaust hole 3a.

[0441] In another example, at least one second exhaust hole among the plurality of second exhaust holes 3 that is laterally disposed at a position farthest from the electronic / electrical component chambers 10 b , 10 c , 10 d may be provided as the common exhaust hole 3 a .

[0442] In another example, at least one of the plurality of second exhaust holes 3 that is laterally aligned and disposed closest to the extension plate 18 may be provided as a common exhaust hole 3 a. In this regard, at least a portion of the common exhaust hole 3 a may be provided to overlap the extension plate 18 in the vertical direction.

[0443] In addition, an exhaust duct 70 may be provided in the upper space 10i. The exhaust duct 70 is configured to guide the flow of air discharged from the cooking chamber 10a to the circulating air discharge hole 11b toward the common exhaust hole 3a.

[0444] In this embodiment, the circulating air discharge hole 11b can be provided at a relatively rearward position around the front-rear center of the cavity 11. For example, the circulating air discharge hole 11b can be provided in the upper surface of the cavity 11 and can be provided at a position adjacent to the right rear corner of the cavity 11.

[0445] The exhaust duct 70 is configured to guide the flow of air discharged to the circulation air discharge hole 11 b provided at the above-defined position toward the common exhaust hole 3 a provided at a position adjacent to the front surface of the main body 10 .

[0446] In addition, the cooking appliance of this embodiment may include an extension plate 18. The extension plate 18 may partition the side space 10e so that a portion 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 can be separated into the extended upper space 10j.

[0447] [Extension board]

[0448] Reference Figure 14 、 Figure 30 and Figure 33 At least a portion of the extension plate 18 may be disposed in the side space 10e. In this embodiment, the extension plate 18 is shown as being disposed in one of the pair of side spaces 10e disposed inside the cooking appliance, rather than in the electronic / electrical component chambers 10b, 10c, and 10d.

[0449] In one example, the extension plate 18 may form a horizontal plane perpendicular to the vertical axis. For example, the extension plate 18 may form a plane parallel to the upper surface of the cavity 11 .

[0450] Preferably, the upper surface of the extension plate 18 and the upper surface of the cavity 11 can form the same plane. The upper surface of the cavity 11 can define the bottom surface of the upper space 10i, and the upper surface of the extension plate 18 can 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 can be coplanar with each other.

[0451] The extended upper space 10j provided as above can be communicated with the upper space 10i while being located above the side space 10e. That is, the extended upper space 10j can be provided 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.

[0452] 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 in the single space while being arranged above the cavity 11 and the extension plate 18.

[0453] The exhaust spaces 10i and 10j formed above the cavity 11 and the extension plate 18 may 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 may connect the upper space 10i and the extended upper space 10j to each other so that a single space therein (i.e., the exhaust spaces 10i and 10j) communicates with the outside of the main body 10.

[0454] The side spaces 10e and the rear space 10f may be connected to the lower space. The side spaces 10e and the rear space 10f may be connected to the lower space in a vertical direction or in a horizontal direction. The air intake hole 1 may be connected to the lower space, and the side spaces 10e and the rear space 10f may be connected to the air intake hole 1 through the lower space.

[0455] A portion of the extension plate 18 may be disposed in the rear space 10 f. Therefore, a portion 18 a of the extension plate 18 (hereinafter referred to as the “side partition portion of the extension plate”) may be disposed in the side space 10 e, and another portion 18 b of the extension plate 18 (hereinafter referred to as the “rear partition portion of the extension plate”) may be disposed in the rear space 10 f.

[0456] As described above, the side partitioning portion 18a of the extension plate 18 can partition the side space 10e so that a portion of the side space 10e is separated into the extended upper space 10j. In addition, the rear partitioning portion 18b of the extension plate 18 can also partition the rear space 10f so that a portion of the rear space 10f is separated into the extended upper space 10j.

[0457] That is, the extension plate 18 may divide the rear space 10 j and the side space 10 f so that a partial area of each of the side space 10 f and the rear space 10 e is separated into the extended upper space 10 a .

[0458] Extension plate 18 may include a first coupling portion 18c. First coupling portion 18c may be provided for coupling between extension plate 18 and cavity 11. In one example, first coupling portion 18c may be formed to protrude horizontally from at least one of side partition 18a and rear partition 18b. First coupling portion 18c may be coupled to cavity 11 while vertically contacting the upper surface of cavity 11.

[0459] The coupling between the first coupling portion 18 c and the cavity 11 may be performed in a joining manner using welding or the like, or may be performed in a fastening manner using screws or the like.

[0460] In this embodiment, the first coupling portion 18c is shown to protrude 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.

[0461] 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 provided for coupling between the extension plate 18 and the box body 13.

[0462] The second coupling portion 18d may be configured to protrude from the side partition portion 18a or the first coupling portion 18c. In this embodiment, the first coupling portion 18c protrudes horizontally from the side partition portion 18a, and the second coupling portion 18d protrudes vertically from the first coupling portion 18c.

[0463] In one example, the second coupling portion 18d may constitute a vertical wall orthogonal to the transverse axis.A flat portion parallel to the upper surface of the box body 13 may be formed at an upper end of the second coupling portion 18d.

[0464] The third coupling portion 18e can be configured to be shaped to protrude from the rear partition portion 18b. In one example, the third coupling portion 18e can constitute a vertical wall orthogonal to the front-rear axis. A flat portion parallel to the upper surface of the box body 13 can be formed at the upper end of the third coupling portion 18e.

[0465] The vertical lengths of the second and third coupling portions 18d and 18e may be set to correspond to the distance between the extension plate 18 and the case 13. The second and third coupling portions 18d and 18e formed as above may be coupled to the case 13 while being positioned below the case 13.

[0466] The extension plate 18 can support the cabinet 13 via the coupling between the second coupling portion 18d and the cabinet 13 and the coupling between the third coupling portion 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 coupled to various structures at various positions using the first coupling portion 18c, the second coupling portion 18d, and the third coupling portion 18e, and thus can be stably fixedly installed inside the cooking appliance.

[0467] As an example, the second coupling portion 18d may be provided between the upper space 10i and the extended upper space 10j. That is, the second coupling portion 18d may 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.

[0468] The second coupling portion 18d may have a plurality of ventilation holes defined therein. The respective ventilation holes may be formed to extend through the second coupling portion 18d in a transverse direction, and the ventilation holes may be provided in most areas of the second coupling portion 18d.

[0469] As described above, the second coupling portion 18d having the plurality of ventilation holes defined therein may serve as a structure for coupling between the extension plate 18 and the case 13 while minimizing interference with air flow in the exhaust spaces 10i and 10j due to the second coupling portion 18d.

[0470] In this embodiment, the third coupling portion 18e is shown as being 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 coupling portion 18e may be provided at a position adjacent to the rear fan assembly 100 provided in the rear space 10f.

[0471] Electronic / electrical components related to the rear fan assembly 100 (e.g., electronic / electrical components such as capacitors connected to the rear fan assembly 100) can be connected to the third connecting portion 18e provided as above. That is, the third connecting portion 18e can provide a structure for connecting the extension plate 18 and the housing 13, and provide a structure for mounting the electronic / electrical components related to the rear fan assembly 100.

[0472] [Exhaust duct]

[0473] Figure 34 is a side sectional view showing an exhaust duct, Figure 35 is a plan view showing a state where the pipe support is installed on the upper surface of the cavity, Figure 36 This is a diagram showing a state where the exhaust duct is mounted on the duct bracket.

[0474] Reference Figures 33 to 35 The exhaust duct 70 may have a flow path defined therein that is connected to the circulating air discharge hole 11a. In one example, the exhaust duct 70 may be formed in a polyhedral shape having a length in the front-to-rear direction much greater than each of its lateral and vertical lengths.

[0475] 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-rear direction and the front surface of the cavity 11.

[0476] For example, the rear end of the exhaust duct 70 may be disposed very close to the rear surface of the cavity 11 , and the front end of the exhaust duct 70 may be disposed very close to the front surface of the cavity 11 .

[0477] A space is formed inside the exhaust duct 70 and may constitute a flow path 70a connected to the circulation 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.

[0478] The duct inlet 70b is configured to open the flow path 70a toward the circulating air discharge hole 11b while being disposed on one side of the flow path 70a in the longitudinal direction. The duct outlet 70c is configured to open the flow path inside the exhaust duct 70 toward the common exhaust hole 3a.

[0479] In one example, the duct inlet 70b may be formed in a form in which a bottom surface of the exhaust duct 70 is opened. At least a portion of the duct inlet 70b may overlap with the circulation air discharge hole 11b in a vertical direction.

[0480] The duct outlet 70c may be formed in a partially open upper surface of the exhaust duct 70. The duct outlet 70c may be provided near the front end around the front-rear center of the exhaust duct 70. The duct outlet 70c may be provided adjacent to the common exhaust hole 3a.

[0481] In the lateral direction, the duct outlet 70c may be provided near the common exhaust hole 3a among the plurality of exhaust holes 2, 3, and 4 provided in the lateral direction. The duct outlet 70c may be provided to overlap at least a portion of the common exhaust hole 3a in the vertical direction.

[0482] The cooking appliance of this embodiment may further include a humidity sensor 7. The humidity sensor 7 is attached to the exhaust duct 70 and is arranged to measure the humidity in the flow path 70a.

[0483] The humidity sensor 7 is configured to measure the humidity of air introduced into the flow path 70b through the circulating air discharge hole 11a in the cooking chamber. In order to effectively measure the humidity of air introduced into the flow path 70a using the humidity sensor 7, the flow path 70a needs to have a sufficient length.

[0484] To this end, the circulating air discharge hole 11b may be provided closer to the rear end of the upper space 10i, the duct outlet 70c may be provided closer to the front end of the upper space 10i, and the exhaust duct 70 may be formed to have a sufficient length to cover them.

[0485] The exhaust duct 70 of this embodiment may be vertically disposed between the upper surface of the cavity 11 and the upper surface of the box body 13. The exhaust duct 70 may include a vertical length-varying section 71.

[0486] The vertical length changing 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 changing section 71 may be a section where the vertical length of the exhaust duct 70 changes in the front-rear direction.

[0487] According to the present embodiment, the circulating 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 case 13. In the vertical length variation section 71, the vertical length of the exhaust duct 70 may also decrease as the exhaust duct 70 moves toward one side (e.g., toward the rear side) in the length direction of the flow path 70a.

[0488] That is, in the vertical length changing section 71 , the upper surface of the exhaust duct 70 may constitute an inclined surface whose vertical height decreases as the exhaust duct 70 extends toward one side in the longitudinal direction of the flow path 70 a .

[0489] In other words, in the vertical length variation section 71 , the vertical length of the exhaust duct 70 may also increase as the exhaust duct 70 moves toward the other side (eg, toward the front side) in the longitudinal direction of the flow path 70 a .

[0490] In the vertical length variation section 71, a passage space 10k may be defined between the upper surface of the exhaust duct 70 and the upper surface of the housing 13. The passage space 10k may constitute a passage connecting the space on one side of the upper space 10i in the transverse direction of the exhaust duct 70 with the space on the other side of the upper space 10i in the transverse direction of the exhaust duct 70, such that the passage is located above the exhaust duct 70. In this embodiment, the vertical dimension of the passage space 10k may increase as the passage space 10k extends toward the rear.

[0491] In one example, the cooking appliance of this embodiment may further include a duct bracket 75. The duct bracket 75 may be provided to couple the exhaust duct 70 to the cavity 11. The duct bracket 75 may be coupled to the upper surface of the cavity 11. In addition, the exhaust duct 70 may be detachably coupled to the duct bracket 75.

[0492] In one example, the pipe support 75 may include a support body 76 and a flange 77 .

[0493] The bracket body 76 is a portion of the duct bracket 75 and is provided for coupling between the duct bracket 75 and the exhaust duct 70. The bracket body 76 may be coupled to the upper surface of the cavity 11 and to the exhaust duct 70.

[0494] The flange 77 is a portion of the pipe bracket 75 and is provided for coupling between the pipe bracket 75 and the cavity 11. The flange 77 is coupled to the upper surface of the cavity 11 to couple the bracket body 76 to the upper surface of the cavity 11.

[0495] The flange 77 may constitute a plane parallel to the upper surface of the cavity 11 and may be configured to vertically contact the upper surface of the cavity 11. The coupling between the flange 77 and the cavity 11 may be performed in a joining manner using welding or the like.

[0496] Reference Figure 35 and Figure 36 , the coupling surface 72 may be provided on the exhaust duct 70. The coupling surface 72 may be provided on the lower end of the exhaust duct 70 and may constitute a surface in contact with the upper surface of the bracket body 76 in the vertical direction. In one example, the upper surface of the bracket body 76 may constitute a horizontal plane orthogonal to the vertical axis, and the coupling surface 72 may constitute a plane parallel thereto.

[0497] The pipe bracket 75 may further include a first pipe coupling portion 78 coupled to the coupling surface 72. The first pipe coupling portion 78 may be detachably coupled to the coupling surface 72 in a state where the coupling surface 72 contacts the bracket body 76 in a vertical direction.

[0498] In one example, the first pipe coupling portion 78 may include a vertical protrusion 78a and a horizontal protrusion 78b. The vertical protrusion 78a may be formed in a shape that protrudes 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-to-back direction).

[0499] In one example, the horizontal protrusion 78b may protrude rearward from an upper end of the vertical protrusion 78a. In the present embodiment, it is shown that the first pipe coupling portion 78 protrudes from the bracket body 76 in a "Γ" shape.

[0500] The vertical protrusion 78a may pass through the slit 73 formed in the coupling surface 72 to vertically penetrate the coupling surface 72. The horizontal protrusion 78b protruding from the upper end of the vertical protrusion 78a may restrict upward movement of the pipe support 75 while being located on the upper side of the coupling surface 72.

[0501] The slit 73 may be defined so that the entire first duct coupling portion 78 may extend through the slit 73. When the exhaust duct moves rearward so that the horizontal protrusion 78b may move to the rear side of the slit 73 in a state where the horizontal protrusion 78b passes through the slit 73 and is disposed above the coupling surface 72 and the coupling surface 72 contacts the upper surface of the bracket body 76, the horizontal protrusion 78b may restrict upward movement of the duct bracket 75 while being located on the upper side of the coupling surface 72.

[0502] The exhaust duct 70 may be temporarily fixed to the duct support 75 via the mating coupling between the first duct coupling portion 78 and the coupling surface 72. That is, the position of the exhaust duct 70 relative to the duct support 75 may be temporarily fixed via the mating coupling between the first duct coupling portion 78 and the coupling surface 72.

[0503] In one example, a plurality of first duct coupling portions 78 may be included in the duct support 75 and may be arranged to be spaced apart from each other by a predetermined interval in the transverse direction. Thus, the exhaust duct 70 may be temporarily fixed at a plurality of points arranged along the transverse direction using the first duct coupling portions 78.

[0504] The duct support 75 may further include a second duct coupling portion 79. The second duct coupling portion 79 may be configured to couple the exhaust duct 70 and the duct support 75 to each other using a fastening member s such as a screw.

[0505] In one example, a fastening member s may pass through an upper surface of the bracket body 76 and the coupling surface 72 to couple the duct bracket 75 to the exhaust duct 70. The second duct coupling portion 79 may be configured to be fastened to the fastening member s.

[0506] In one example, the second pipe coupling portion 79 may constitute a convex surface upward from the upper surface of the bracket body 76 , and a fastening hole for fastening with a fastening member s may be defined in the second pipe coupling portion 79 .

[0507] As described above, the exhaust duct 70 may be installed on the upper surface of the cavity 11 via the duct bracket 75 .

[0508] In order to install the exhaust duct 70 on the cavity 11 so that the exhaust duct 70 can be removed from the cavity 11 as needed, it is necessary to couple the exhaust duct 70 to the cavity 11 using a fastening member such as a screw.

[0509] However, in this case, a fastening hole for screw fastening should be formed in the cavity 11 , and it is not preferable that unnecessary damage be applied to the cavity 11 due to the fastening hole.

[0510] Furthermore, damage to the cavity 11 may further increase during tightening of the screws to the cavity 11 , and the cavity 11 may be severely damaged during removal of the screws from the cavity 11 or re-tightening of the screws to the cavity 11 to disassemble and reassemble the exhaust duct 70 .

[0511] To prevent damage to the cavity 11, the exhaust duct 70 may be welded or bonded to the cavity 11. However, in this case, it is very difficult to remove the exhaust duct 70 from the cavity 11, and the cavity 11 may be damaged during the removal process.

[0512] In consideration of this fact, in the present embodiment, the duct holder 75 is joined to the cavity 11 in a welding or bonding manner, and the exhaust duct 70 may be detachably coupled to the duct holder 75 .

[0513] Therefore, the cavity body 11 and the pipe support 75 are coupled to each other in a welding or bonding manner, whereby damage to the cavity body 11 due to perforation or the like can be minimized.

[0514] In addition, the exhaust duct 70 is detachably coupled to the duct bracket 75 coupled to the cavity 11 as described above. Therefore, the exhaust duct 70 can be easily and quickly removed from the cavity 11 as needed, and damage to the cavity 11 that may occur during disassembly and reassembly of the exhaust duct 70 can be minimized.

[0515] In addition, through the fitting connection between the first duct coupling portion 78 and the coupling surface 72, the coupling position of the exhaust duct 70 relative to the duct bracket 75 can be guided, and the exhaust duct 70 can be temporarily fixed to the duct bracket 75. Therefore, the installation of the exhaust duct 70 can be performed relatively easily and quickly.

[0516] [An example of a lampshade]

[0517] Figure 37 This is an enlarged view of the lampshade and its surroundings. Figure 38 yes Figure 37 Plan view of the lampshade shown.

[0518] Reference Figure 31 、 Figure 37 and Figure 38 , the lamp 8 may be disposed inside the body 10. The lamp 8 is configured to irradiate light toward the cooking chamber 10a.

[0519] In one example, the lamp 8 may be mounted on the upper surface of the cavity 11. At least a portion of the lamp 8 may be exposed from the upper side of the cavity 11. For example, a portion of the lamp 8 mounted on the upper surface of the cavity 11 may be exposed from the upper space 10i.

[0520] The cooking appliance of this 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 so that the space surrounding the lamp 8 is blocked from the upper space 10i.

[0521] 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 side of the lamp.

[0522] In one example, the cover upper surface portion 81 may constitute a horizontal surface that is vertically spaced a predetermined distance apart from the upper surface of the cavity 11. The cover side surface portion 82 may constitute a vertical wall surface connecting the upper surface of the cavity 11 and the cover upper surface portion 81 to each other.

[0523] 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 provided in a manner surrounded by a cover upper surface portion 81 and a cover side surface portion 82 .

[0524] The lampshade 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 constitute a plane parallel to the upper surface of the cavity 11.

[0525] The close contact portion 83 can be in surface contact with the upper surface of the cavity 11 and can be used to allow the lampshade 80 to be in close contact with the upper surface of the cavity 11. As a result, the space inside the lampshade 80 surrounding the lamp 8 can be reliably blocked from the upper space 10i, and the inflow of air from the upper space 10i into the lampshade 80 can be effectively suppressed.

[0526] The lampshade 80 of this embodiment may be disposed vertically between the upper surface of the cavity 11 and the upper surface of the box body 13. In addition, the lampshade 80 may be disposed adjacent to the front surface of the main body 10.

[0527] 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. An upper end surface portion 12a may be disposed at the upper end of the front plate 12. The upper end surface portion 12a may constitute a horizontal surface that protrudes rearward and is positioned at a position on the top of the cavity 11.

[0528] The lamp cover 80 may be disposed adjacent to the front plate 12. In one example, the lamp cover 80 may be disposed at a position where a front end of the lamp cover 80 is in close contact with a rear surface of the front plate 12.

[0529] The cover upper surface portion 81 of the lampshade 80 may also constitute an inclined surface whose vertical height changes along the front-rear direction. In one example, the cover upper surface portion 81 may constitute an inclined surface whose vertical level decreases as the cover upper surface portion 81 extends toward the rear side.

[0530] The lamp cover 80 may be coupled to the front plate 12. The lamp cover 80 may include a cover coupling portion 84 therein. The cover coupling portion 84 may protrude rearward from the lamp cover 80 to contact the upper end surface portion 12a of the front plate 12 in the vertical direction.

[0531] The cover coupling portion 84 may be formed in a shape that protrudes upward and rearward from the front end of the cover upper surface portion 81. In one example, the cover coupling portion 84 may be formed in a "Γ" shape that protrudes from the front end of the cover upper surface portion 81. In one example, the coupling between the cover coupling portion 84 and the upper end surface portion 12a may be performed using a fastening member s such as a screw.

[0532] 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 in close contact only 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 body 10 while avoiding unnecessary damage to the cavity 11.

[0533] To this end, the lamp cover 80 may be coupled to the front plate 12 via the cover coupling portion 84 and the upper end portion 12a and thus may be detachably coupled to the body 10. That is, the cover coupling portion 84 may be configured to couple the lamp cover 80 to the front plate 12 rather than to the cavity 11.

[0534] According to this embodiment, at least a portion of lamp 8 is exposed inside cooking chamber 10a to illuminate cooking chamber 10a. Furthermore, to facilitate connection of lamp 8 to other electrical and electronic components, a portion of lamp 8 is exposed outside cooking chamber 10a. For example, a power supply wire can be connected to lamp 8 through the portion of lamp 8 exposed outside cooking chamber 10a.

[0535] According to this embodiment, the lamp 8 is mounted on the upper surface of the cavity 11, and accordingly, a portion of the lamp 8 is exposed to the upper space 10i, which is the space above the cavity 11. When this portion of the lamp 8 is exposed to the upper space 10i, the lamp 8 may be exposed to oil vapor and heat.

[0536] The cooking gas drawn 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, thereby causing contamination, malfunction, etc. of the lamp 8.

[0537] Considering this situation, in this embodiment, the lampshade 80 is installed in the upper space 10i. The lampshade 80 can protect the lamp 8 from oil vapor and heat by covering the lamp 8 while being arranged above the cavity 11, so that the space around the lamp 8 is separated from the upper space 10i.

[0538] In conventional cooking appliances, the blower is installed in the upper chamber rather than the rear chamber. In this case, sufficient space must be secured in the upper chamber to accommodate the blower. In such conventional cooking appliances, the vertical length of the upper chamber should be significantly greater than the vertical length of the upper chamber 10i of the cooking appliance of this embodiment.

[0539] In addition, since the blower is provided in the upper space, a flow path defining member for defining an exhaust flow path in the upper space is installed in the conventional cooking appliance. The flow path defining member defines an exhaust flow path that connects the exhaust hole provided in the front surface of the conventional cooking appliance and the blower, so that the exhaust flow path is located in the upper space.

[0540] In conventional cooking appliances, the flow path defining member may be formed into a shape including a pair of side walls spaced a predetermined distance apart in the transverse direction and a bottom surface connecting the side walls at their lower sides. For example, the flow path defining member may be formed into a "U" shape.

[0541] The flow path defining member may be mounted on the upper side of the cavity. The flow path defining member may be detachably mounted on the upper side of the cavity, with a lower surface of the flow path defining member resting on an upper surface of the cavity.

[0542] The lamp, mounted on the upper surface of the cavity, is positioned below the flow path defining member. In other words, in conventional cooking appliances, the lamp is covered by the bottom surface of the flow path defining member and is not exposed to the exhaust flow path. Therefore, conventional cooking appliances do not require a separate structure to cover the lamp, in addition to the flow path defining member.

[0543] In contrast, in the cooker of this embodiment, the blowers 100 and 200 are located in the rear space 10f. Therefore, the cooker of this embodiment does not need to secure the space required to install the blowers 100 and 200 in the upper space 10i. In the cooker of this embodiment, the vertical length of the upper space 10i can be significantly reduced compared to the vertical length of the upper space in conventional cookers.

[0544] As the vertical length of the upper space 10i decreases, it becomes difficult to secure space within the upper space 10i for structures such as the flow path defining member of conventional cooking appliances. Furthermore, in the cooking appliance of this embodiment, the blowers 100 and 200 and the flow path defining member 30 are disposed in the rear space 10f, eliminating the need for structures defining the exhaust flow path to be installed in the upper space 10i.

[0545] As the vertical length of the upper space 10i decreases, the vertical length of the cooking appliance can be shortened, and the overall size of the cooking chamber can be reduced relative to the volume of the cooking chamber 10a. However, conventional cooking appliances do not include flow path defining structures such as the upper space 10i, so the lamp 8 is exposed in the upper space 10i.

[0546] Taking this into consideration, in this embodiment, a lampshade 80 is installed in the upper space 10i. The lampshade 80 can also cover the lamp 8 while being positioned above the cavity 11, thereby blocking the space surrounding the lamp 8 from the upper space 10i. Thus, the vertical length of the upper space 10i can be reduced while protecting the lamp 8 from oil vapor and heat.

[0547] [Other examples of lampshades]

[0548] Figure 39 is a rear perspective view of a cooking appliance showing another example of applying a lampshade, and Figure 40 It shows that Figure 39 A perspective view of the cooking appliance is shown with the lampshade detached. Figure 41 It shows Figure 40 The exploded perspective view of the lampshade in the exploded state shown in FIG. Figure 42 It is an exploded perspective view showing the exploded state of the ventilation grille and the lamp cover.

[0549] Reference Figures 39 to 41 The lampshade 85 may include an opening and closing cover 86b. The lampshade 85 may 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 lampshade shown in the above embodiment, and may further include an opening and closing cover 86b.

[0550] A through hole 86a may be defined in the upper surface of the lamp housing 85 of the present embodiment. The through hole 86a may open the upper side of the interior space of the lamp housing 85 and may be formed to extend vertically through the housing upper surface portion 86. The lamp 8 may be exposed at a position on the top of the lamp housing 85 through the through hole 86a.

[0551] An opening and closing cover 86b is mounted in the lamp housing 85, more specifically, in the housing upper surface portion 86, to open and close the through-hole 86a. In one example, the opening and closing cover 86b can be detachably coupled to the cover upper surface portion 86. For example, the opening and closing cover 86b can be positioned on top of the through-hole 86a while covering the through-hole 86a, and can be removed from the upper surface of the housing 86 while being positioned on top of the housing 86.

[0552] Reference Figures 39 to 42 , the lampshade 85 may be disposed below one of the plurality of second exhaust holes 2. For example, at least a portion of the lampshade 85 may be disposed below one of the plurality of second exhaust holes 2 in a vertical direction.

[0553] 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.

[0554] For example, each ventilation grille 9 is placed on the upper surface of the box body 13 to cover the second exhaust hole 3 or the cold air inlet 5 , and is lifted upward from the upper surface of the box body 13 to be separated from the box body 13 .

[0555] In one example, the opening and closing cover 86b can be vertically positioned below one of the plurality of second exhaust holes 2. Vertically, the through-hole 86a can be positioned between the second exhaust hole 3 and the lamp 8, and the opening and closing cover 86b can be positioned between the ventilation grille 9 mounted in the second exhaust hole 3 and the lamp 8. In a top view, when the ventilation grille 9 is removed from the second exhaust hole 3, the opening and closing cover 86b is visible from the top of the cooking appliance. In this state, the opening and closing cover 86b is removed, allowing the lamp 8 to be visible from the top of the cooking appliance.

[0556] Since the lamp cover 85 and the opening and closing cover 86 b are installed inside the main body 10 in the above-described manner, maintenance work on the lamp 8 can be performed with the ventilation grille 9 and the opening and closing cover 86 b removed from the box body 13 and the cover upper surface portion 86 in sequence.

[0557] That is, the lamp cover 85 according to the present embodiment allows access to the lamp 8 by a simple operation of separating the ventilation grille 9 and the opening and closing cover 86 b , thereby achieving an effect of enabling easy and quick maintenance work on the lamp 8 .

[0558] [Exhaust through exhaust space]

[0559] Reference Figure 16 and Figures 31 to 33, the upper space 10i may be formed above the cavity 11. In addition, the extended upper space 10j may be formed above the side space 10b, rather than above the electronic / electrical component chambers 10e, 10c, 10d.

[0560] 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, and thus, the exhaust spaces 10i and 10j may be formed above the cavity 11 and the side space 10e.

[0561] The extended upper space 10j can be defined by an extension plate 18 that vertically separates the side space 10e. In this embodiment, the extension plate 18 can be used to extend the exhaust spaces 10i and 10j in the lateral direction by allowing the exhaust spaces 10i and 10j to become spaces that include not only the upper space 10i but also the extended upper space 10j. In addition, the extension plate 18 can also serve to block the side space 10e from the exhaust spaces 10i and 10j.

[0562] When the exhaust spaces 10i and 10j are extended to include both the upper space 10i and the extended upper space 10j, it is possible to increase 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. 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.

[0563] That is, the extension plate 18 according to the present embodiment divides the side space 10e so 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.

[0564] As described above, in the cooking apparatus according to the present embodiment, the blowers 100 and 200 are disposed in the rear space 10i rather than in the upper space 10f. Therefore, since the upper space 10i does not require space for installing the blowers 100 and 200, 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.

[0565] In the cooking appliance according to the present embodiment, one of the methods for reducing the overall size of the cooking appliance while minimizing the reduction in the volume of the cooking chamber (i.e., a method for reducing the overall 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.

[0566] Taking this into consideration, the vertical length of the upper space 10i in the cooking appliance of this embodiment is set to be smaller than that of the upper space of a conventional cooking appliance. In other words, the vertical length of the upper space 10i in the cooking appliance of this embodiment is set to be significantly smaller than the vertical length in which the rear fan assembly 100 or the corner fan assembly 200 can be installed.

[0567] As described above, as the vertical length of the upper space 10i decreases, the volume of the upper space 10i inevitably decreases. In this regard, the upper space 10i is relevant to exhaust. Thus, as the volume of the upper space 10i decreases, the size of the flow path required for the air discharged to the second exhaust hole 3 inevitably decreases by the amount of the decrease in volume.

[0568] When the size of the flow path required for the air discharged to the second exhaust hole 3 is reduced, the exhaust performance of the cooking appliance inevitably deteriorates. In addition, when the exhaust performance of the cooking appliance deteriorates, the air intake performance of the cooking appliance also inevitably deteriorates, and ultimately, the cooking gas removal performance of the cooking appliance deteriorates.

[0569] Taking this into consideration, in this embodiment, the extended upper space 10e is blocked from the side space 10e by an extension plate 18 that vertically divides the side space 10j, while the extended upper space 10j is connected to the upper space 10i. This increases the combined size of the exhaust spaces 10i and 10j, including the upper space 10i. Consequently, the size of the flow path required for the air discharged through the exhaust spaces 10i and 10j to the second exhaust port 3 can be effectively increased.

[0570] As described above, when the size of the flow path required for the flow of air discharged to the second exhaust hole 3 through the exhaust spaces 10i and 10j increases, exhaust performance of the cooking appliance may be improved accordingly, and as a result, cooking gas removal performance of the cooking appliance may be improved.

[0571] In one example, the exhaust spaces 10i and 10j are provided with exhaust ducts 70, lamp housings 80, and other structures. These structures are shaped to protrude from the upper surface of the cavity 11 into the exhaust spaces 10a and 10j to perform their respective functions.

[0572] For example, the exhaust duct 70 is formed in a shape protruding from the upper surface of the cavity 11 and has a flow path defined therein for the airflow discharged from the cooking chamber. The lamp cover 80 is formed in a shape protruding from the upper surface of the cavity 11 to cover the upper side of the lamp and is coupled to the front plate 12.

[0573] 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 flow resistance generated by the exhaust duct 70 and the lamp cover 80 in the exhaust spaces 10a and 10j.

[0574] That is, according to the present embodiment, the size of the exhaust spaces 10i and 10j is increased by the extended upper space 10j, so that the size of the flow path required for the flow of air discharged to the second exhaust hole 3 through the exhaust spaces 10i and 10j 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 to the second exhaust hole 3 through the exhaust spaces 10i and 10j can be performed smoothly.

[0575] Thus, the cooking appliance of the present embodiment may provide cooking gas removal performance equal to or higher than conventional cooking appliances having similar cooking capabilities, while having an overall size smaller than conventional cooking appliances having similar cooking capabilities.

[0576] In addition, the extension plate 18 may function as a barrier wall that blocks the side space 10e and the exhaust spaces 10i and 10j from each other. Accordingly, the side space 10e may be blocked from the exhaust spaces 10i and 10j via the extension plate 18.

[0577] That is, a space in which the upper space 10 i and the extended upper space 10 j communicate with each other is formed above the extension plate 18 via the extension plate 18 , while the side space 10 e and the exhaust spaces 10 i and 10 j are blocked from each other via the extension plate 18 .

[0578] According to this embodiment, the side space 10e is connected to the lower space defined between the air intake hole 1 and the cavity 11. Therefore, the side space 10e can be referred to as a space connected to the air intake hole 1. In addition, the exhaust spaces 10i and 10j can be referred to as spaces connected to the second exhaust hole 3. In other words, 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 exhaust.

[0579] The extension plate 18 can block the exhaust spaces 10i and 10j from the side space 10e, thereby blocking the space related to gas exhaust from the space related to air intake. Therefore, the space related to exhaust is increased by the extended upper space 10j, and the space related to air intake is increased by the space occupied by the side space 10e.

[0580] That is, since the exhaust spaces 10i and 10j and the side space 10e block each other via the extension plate 18, the space involved in gas exhaust and the space involved in air intake can be ensured to have sufficient sizes required for gas exhaust and air intake, respectively.

[0581] In addition, since the exhaust spaces 10i and 10j and the side space 10e are blocked from each other via the extension plate 18, the air in the exhaust spaces 10i and 10j can be effectively prevented from being sucked back into the blowers 100 and 200, i.e., a backflow phenomenon, thereby effectively improving the cooking gas exhaust performance of the cooking appliance.

[0582] In one example, in the cooking appliance of this embodiment, a plurality of second exhaust holes 3 may be provided. Each second exhaust hole 3 may be defined in the upper surface of the body 10, may be provided at a position adjacent to the front surface of the body 10, and may communicate with the exhaust spaces 10i and 10j.

[0583] In the body 10, a cool air inlet 5 and a plurality of second exhaust holes 3 may be defined and arranged in a transverse direction. In addition, one of the plurality of second exhaust holes 3 may be provided as a common exhaust hole 3a.

[0584] In this embodiment, the cold air inlet 5 is provided on the left side of the second exhaust hole 3 , and the cold air inlet provided on the rightmost side among the plurality of second exhaust holes 3 is provided as the common exhaust hole 3 a .

[0585] At least a portion of the common exhaust hole 3a may be arranged to overlap at least a portion of the duct outlet 70c provided in the exhaust duct 70. That is, in a top view, at least a portion 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.

[0586] A portion of the air introduced into the electronic / electrical component rooms 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 may be discharged to the exhaust duct 70 together with steam, gas, etc. generated in the cooking chamber 10a during the cooking process of the cooking appliance.

[0587] The air introduced into the exhaust duct 70 can be discharged through the duct outlet 70c, and the air discharged from the exhaust duct 70 can be discharged to the outside of the cooking appliance through the common exhaust hole 3a. That is, the common exhaust hole 3a can be used as an outlet for discharging the air discharged from the cooking chamber to the outside of the cooking appliance.

[0588] In this embodiment, at least a portion of the common exhaust hole 3a is positioned to the left of the extended upper space 10j. The common exhaust hole 3a can be positioned above the boundary between the upper space 10i and the extended upper space 10j. In other words, in a top view of the cooking appliance, the boundary between the upper space 10i and the extended upper space 10j can be exposed at a position on the top of the cooking appliance through the common exhaust hole 3a.

[0589] In one example, a substantially left half of the common exhaust hole 3a may be disposed above the upper space 10i. In addition, the other half of the common exhaust hole 3a may be disposed above the extended upper space 10j.

[0590] 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, 10j from the blowers 100, 200. That is, the steam and gas discharged from the cooking chamber and the cooking gas sucked by the blowers 100, 200 can be discharged together through the common exhaust hole 3a.

[0591] 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 by 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.

[0592] In this regard, the air flowing from the blowers 100 and 200 to the extended upper space 10j may not necessarily be discharged to the outside of the cooking appliance only through the common exhaust hole 3a, but may also be discharged to the outside of the cooking appliance through the second exhaust hole 3 in addition to the common exhaust hole 3a.

[0593] If the extension plate 18 is not provided in the main body 10 , and thus the extended upper space 10 j is not formed in the main body 10 , the area occupied by the exhaust spaces 10 i and 10 j is inevitably reduced to only the upper space 10 i .

[0594] In this case, most of the area below the common exhaust hole 3a is occupied by the exhaust duct 70, and thus it is difficult to form a passage connecting the common exhaust hole 3a and the exhaust spaces 10a and 10j to each other.

[0595] In addition, if the extension plate 18 is not provided inside the main body 10, the common exhaust hole 3a is directly connected to 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.

[0596] In this case, the air flowing from the blowers 100 and 200 to the exhaust spaces 10i and 10j is difficult to be discharged to the outside of the cooking appliance through the common exhaust hole 3a. As a result, only the steam and gas exhausted 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 be almost not discharged.

[0597] In contrast, in the cooking utensil of the present embodiment, the side space 10e and the upper extended upper space 10j are blocked from each other via the extension plate 18, and the area occupied by the exhaust spaces 10i and 10j can extend not only to the upper space 10i, but also to the upper extended upper space 10j arranged below the common exhaust hole 3a.

[0598] Therefore, the cooking appliance of the present embodiment may discharge steam and gas exhausted from the cooking chamber and cooking gas sucked by the blowers 100 and 200 through the common exhaust hole 3 a .

[0599] [Rear support member]

[0600] Figure 43 is a rear perspective view showing a state in which a rear fan assembly is removed from the cooking appliance according to the first embodiment of the present disclosure, Figure 44 It is shown from Figure 43 A rear perspective view of the cooking appliance shown with the rear support member separated, Figure 45 is a side view showing a coupled state of the cavity and the rear support member. Figure 46 It shows that Figure 45 A bottom perspective view showing an enlarged state of a coupling portion between the cavity and the rear support member. Figure 47 The rear plate is shown coupled to Figure 45 A side view of the state of the rear support member shown, and Figure 48 is a side sectional view showing a coupling structure between the cavity, the rear support member, and the rear plate.

[0601] Reference Figures 43 to 45 The cooking appliance of this embodiment may include a rear support member 90. The rear support member 90 may be provided at the rear of the cavity 11.

[0602] As described above, the front plate may be disposed in front of the cavity 11. With the cavity 11 interposed therebetween, the front plate 12 and the rear support member 90 may be spaced apart from each other in the front-to-rear direction and may be coupled to the cavity 11.

[0603] 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.

[0604] 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 that 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.

[0605] Similar to the front plate 12, the rear support member 90 may be formed such that its lower end is disposed at a vertical height lower than that 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.

[0606] To this end, at least a portion of the rear support member 90 may protrude to a position lower than 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 that of the cavity 11 and may support the cavity 11.

[0607] The rear support member 90 may include a front coupling portion 91 and a lower support piece 92. The front coupling portion 91 is configured to be coupled to the rear surface of the cavity 11. In addition, the lower support piece 92 may protrude downward from the front coupling portion 91.

[0608] The lower end of the lower support member 92 may be disposed at a position lower than the bottom surface of the cavity 11. The lower support member 92 may be in contact with the bottom surface of the cavity 11 while being disposed at a position lower than the cavity 11, and may support the front coupling portion 91 and the cavity 11 coupled thereto.

[0609] Preferably, the lower end of the lower support member 92 may be positioned 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 member 92 relative to the bottom surface of the cavity 11 may be set to be the same as the protruding length of the front plate 12 relative to the bottom surface of the cavity 11. Therefore, the rear support member 90 can support the cavity 11 so that the cavity 11 can be maintained in a substantially horizontal state.

[0610] 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.

[0611] To this end, the rear support member 90 may further include a rear coupling portion 93 and a connecting portion 94. The rear coupling portion 93 is configured to be coupled to the front surface of the rear plate 15. In addition, the connecting portion 94 protrudes rearward from the front coupling portion 91 and may connect the front coupling portion 91 and the rear coupling portion 93 to each other.

[0612] The connection portion 94 may be provided in the rear space 10f and may be provided below the rear fan assembly 100. In the vertical direction, the connection portion 94 may be provided 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 passing through the connection portion 94.

[0613] To this end, the rear support member 90 may have a vertical through hole 94 a defined therein. The vertical through hole 94 a 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 .

[0614] In one example, the connecting portion 94 may constitute a horizontal surface that blocks the lower space and the rear fan assembly 100, and the vertical through hole 94a may be formed to extend vertically through the connecting portion 94. The vertical through hole 94a may constitute a passage required for the air introduced into the lower space through the air intake hole 1 to flow through the rear support member 90 and toward the rear fan assembly 100.

[0615] That is, the connection portion 94 may serve to maintain the interval between the cavity 11 and the rear plate 15 , thereby ensuring a sufficient space required for the flow of air in the rear space 10 f .

[0616] Reference 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.

[0617] The connection between the cavity 11 and the front coupling portion 91 can be performed via at least one of a connection using a fastening member s such as a screw or a mating connection. In one example, at least one of a mating connection portion 91a and a fastening hole 91b can be provided in the front coupling portion 91. In this embodiment, both the mating connection portion 91a and the fastening hole 91b are provided in the front coupling portion 91.

[0618] The fitting coupling portion 91a may be detachably coupled to the rear surface of the cavity 11. In one example, a lower end 11c of the rear surface of the cavity 11 may be formed to protrude downward beyond the lower surface of the cavity 11. The fitting coupling portion 91a is configured such that the lower end 11c of the rear surface of the cavity 11 may be fittingly coupled to the fitting coupling portion 91a.

[0619] In one example, the mating connection portion 91a may be formed to protrude rearward from the front connection 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 connection portion 91 and the rear surface of the mating connection portion 91a.

[0620] When assembling the cooking appliance, with the cavity 11 turned upside down so that the bottom surface of the cavity 11 faces upward, and with the rear support member 90 turned upside down so that the lower support piece 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 fits into the fitting portion 91a. Thus, the fitting connection between the cavity 11 and the rear support member 90 is achieved.

[0621] The rear support member 90 can be temporarily fixed to the cavity 11 via the fitting connection 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 manner, the front coupling portion 91 can contact the rear surface of the cavity 11 in the front-to-rear direction.

[0622] In this state, a fastening member s such as a screw is fastened to the fastening hole 91 b , so that the rear support member 90 can be firmly coupled to the cavity 11 .

[0623] That is, through the mating connection between the cavity 11 and the mating connection part 91a, the connection 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, so that the installation of the rear support member 90 can be performed more easily and quickly.

[0624] The rear support member 90 installed at the rear side of the cavity 11 as described above can support the cavity 11 so that the cavity 11 does not fall backward when the assembly process of the cooking appliance is being performed.

[0625] As described above, the front panel 12 is mounted 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 mounted on the cavity 11 and the bottom panel 14 or the rear panel 15 has not yet been mounted on the cavity, the cavity 11 is likely to fall backward due to the difference in vertical length between the front and rear sides of the cavity 11.

[0626] Taking this into consideration, 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 plate 12 and the rear support member 90 are provided in the front-to-rear direction with the cavity 11 interposed therebetween, and the cavity 11 may be supported while being provided on two opposite sides of the cavity 11 in the front-to-rear direction, respectively.

[0627] Therefore, even in a state where the front plate 12 is first mounted on the cavity 11 and the bottom plate 14 or the rear plate 15 has not yet been mounted on the cavity, the cavity 11 does not fall backward and can maintain a stable posture without tilting toward the front or rear side.

[0628] In other words, the rear support member 90 according to this embodiment is used to stably maintain the posture of the cavity 11, so that the cavity 11 does not fall backward during the assembly process of the cooking appliance, thereby facilitating the convenient assembly of the cooking appliance in a relatively stable environment. Therefore, various safety accidents that may occur due to the falling of the cavity 11 during the assembly process of the cooking appliance can be suppressed.

[0629] In addition, the rear support member 90 may be coupled to at least one of the rear plate 15 and the bottom plate 14, as shown in FIG. Figure 47 and Figure 48 In this embodiment, the rear support member 90 is shown coupled to both the rear plate 15 and the bottom plate 14 .

[0630] As described above, the rear coupling portion 93 may be coupled to the rear panel 15. The lower end of the lower support piece 92 may be coupled to the bottom panel 14. The rear support member 90 coupled to each of the rear panel 15 and the bottom panel 14 stably supports the rear panel 15 and the bottom panel 14 on the cavity 11, thereby effectively improving the structural stability of the cooking appliance.

[0631] In addition, the rear support member 90 may provide an effect of increasing the suction flow rate by maintaining a gap between the cavity 11 and the rear plate 15 , thereby ensuring a sufficient space required for the air flow in the rear space 10 f.

[0632] [Further examples of cooking utensils]

[0633] Figure 49 is a rear perspective view showing a state in which a 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 a cabinet is removed from the cooking appliance according to the third embodiment of the present disclosure, Figure 51 1 is a rear perspective view showing a state in which a cabinet is removed from the cooking appliance according to the fourth embodiment of the present disclosure.

[0634] like Figures 49 to 51 The main difference between the cooking appliance shown and the cooking appliances shown in the above embodiments is the angular fan assembly 200 (see Figure 5 ) exists or does not exist. Figures 49 to 51 As shown, only the rear fan assembly 100 is provided in the cooking apparatus, and the corner fan assembly 200 is not provided.

[0635] Therefore, if Figures 49 to 51There is a difference between the blower output of the cooking appliance shown in FIG. 1 and the blower output of the cooking appliance shown in the above embodiment. That is, compared with the cooking appliance including both the corner fan assembly 200 and the rear fan assembly 100, as shown in FIG. Figures 49 to 51 The output of the blower in the cooking appliance shown is relatively reduced.

[0636] like Figures 49 to 51 The cooking appliance shown can adopt a main body 10 having a shape substantially the same as that of the main body of the cooking appliance shown in the above embodiment. That is, the cooking appliance according to this embodiment can be provided as various types of cooking appliances that adopt only one type of common main body but have only different blower outputs.

[0637] The cooking appliance according to the present embodiment can provide an 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-mentioned object are shown.

[0638] Reference Figure 49 , the structure of the cooking appliance according to the second embodiment of the present disclosure is substantially the same as that of the cooking appliance shown in the above-described embodiment, except for the blower and the flow path defining member 300 .

[0639] That is, the main differences between the cooking appliance according to the second embodiment of the present disclosure and the cooking appliances shown in the above-described embodiments are the blower and the flow path defining member 300 .

[0640] The flow path defining member 300 of this embodiment may include a first flow path plate 31 and a fastening plate 33. For example, the flow path defining member 300 of this embodiment may also be formed by changing the flow path defining member 30 shown in the above embodiment (see Figure 6 ) is set in a manner in which the second flow path plate 32 is omitted.

[0641] In one example, the flow path defining member 300 of this 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.

[0642] Therefore, no structure that can block the first suction hole 112 and the first discharge hole 114 from each other is provided on the left side of the rear fan assembly 100. In addition, the corner spaces 10g and 10h, more specifically, the lower corner space 10h, remain empty.

[0643] The cooking appliance of this embodiment may further include a cover 36. The cover 36 is configured to cover the through hole 41b formed in the transverse support member 41 (see Figure 21). The cover 36 may be coupled to the lateral support member 41 to close the discharge hole 41a. Due to the cover 36, an unnecessary passage between the corner spaces 10g, 10h and the exhaust flow path A may be closed.

[0644] Reference Figure 50 , the flow path defining member 400 provided in the cooking apparatus according to the third embodiment of the present disclosure may be configured to include a first flow path plate 31 , an extending plate 34 , and a fastening plate 33 .

[0645] In one example, the flow path defining member 400 of the present embodiment may 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 may 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.

[0646] In the flow path defining member 400 , the first flow path plate 31 may define the right boundary of the exhaust flow path A. The extension plate 34 forms the left boundary of the exhaust flow path A and is disposed on the left side of the rear fan assembly 100 , and constitutes a wall blocking the first suction hole 112 and the first discharge hole 114 .

[0647] In addition, refer to Figure 51 The cooking appliance according to the fourth embodiment of the present disclosure may include a flow path defining member 30 having the same shape as that shown in the first embodiment of the present disclosure. In addition, the cooking appliance according to the fourth embodiment of the present disclosure may further include a cover 36 having the same shape as that shown in the second embodiment of the present disclosure.

[0648] 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 transverse support member 41 and the cover 36.

[0649] Although the present disclosure has been described above with reference to the embodiments shown in the accompanying drawings, this is merely an example, and those skilled in the art will appreciate that various modifications and other equivalent embodiments may be made therefrom. Therefore, the true technical protection scope of the present disclosure should be determined by the appended claims.
