Description

TECHNICAL FIELD

[0001] The utility model relates to a cooking equipment, more particularly, to a cooking equipment providing cooking function and oil fume extraction function. BACKGROUND

[0002] The cooking equipment is one of home appliances for cooking food, and is an equipment which is installed in a kitchen space and cooks food according to a user's intention. Such a cooking equipment can be classified into various types according to a heat source or a form used, or a type of fuel.

[0003] If classified according to a form of cooking food, the cooking equipment can be classified into an open type cooking equipment and a closed type cooking equipment according to a form of a space where food is placed. The closed type cooking equipment includes an oven, an electromagnetic microwave oven, etc., and the open type cooking equipment includes a cooktop, a range, etc.

[0004] The closed type cooking equipment is an equipment which shelters a space where food is placed and cooks food by heating the sheltered space. The closed type cooking equipment provides a chamber, i.e., a cooking chamber, as a space where food is placed and is sheltered when cooking food, inside a main body. Such a cooking chamber is a space where food is substantially cooked. A heat source is provided in an inner or outer space of the cooking chamber to heat the cooking chamber.

[0005] The electromagnetic microwave oven in the closed type cooking equipment is an equipment which generates microwaves using electricity and makes them penetrate into a cooking object contained inside a cooking chamber, thereby heating the cooking object by generating molecular motion inside it.

[0006] The electromagnetic microwave oven is a kitchen appliance which simultaneously heats the inside and outside of food by irradiating the food with high frequency of a magnetron, has advantages of greatly reducing a cooking time of food since a thermal efficiency is high, being able to reduce a loss of a nutritional value during cooking, thawing, and heating of food, being able to directly cook food in a state where the food is stored in a container, etc., and thus is widely used.

[0007] In recent years, an electromagnetic microwave oven with a hood function, also called an OTR (Over the range) type electromagnetic microwave oven, is continuously emerging. The electromagnetic microwave oven with a hood function has a hood function of discharging air (hereinafter, referred to as "cooking gas") containing foreign substances generated during cooking of food by a cooking equipment installed below it to the outside or discharging it to the indoor after being filtered.

[0008] Such an electromagnetic microwave oven with a hood function is provided with a fan for sucking and discharging air. The fan is usually disposed at an upper side of a cavity forming a cooking chamber. That is, in the electromagnetic microwave oven with a hood function, the fan is usually disposed at a position higher than the cavity.

[0009] However, if the fan is disposed at the position as described above, the distance between the suction port disposed at the lower end of the range hood-compatible microwave oven and the fan increases by a distance equivalent to the length of the cavity in the up-and-down direction. Therefore, as described above, if the distance between the suction port and the fan becomes farther, the cooking gas capturing performance of the range hood-compatible microwave oven can only be reduced. This is because the flow rate of the suction airflow generated by the fan decreases in inverse proportion to the square of the distance from the fan.

[0010] In addition, if the fan is disposed at the position as described above, the total length of the range hood-compatible microwave oven in the up-and-down direction can only increase. As described above, if the length of the range hood-compatible microwave oven in the up-and-down direction increases, when the range hood-compatible microwave oven is disposed in the upper storage cabinet, the possibility that the range hood-compatible microwave oven protrudes more to the lower side than the upper storage cabinet increases.

[0011] If the range hood-compatible microwave oven protrudes more to the lower side than the upper storage cabinet, not only is it unattractive, but also the problem that the gap between the cooktop disposed at the lower portion of the upper storage cabinet and the range hood-compatible microwave oven becomes narrow arises.

[0012] If the gap between the cooktop and the range hood-compatible microwave oven becomes narrow as the range hood-compatible microwave oven protrudes to the lower side of the upper storage cabinet, the problem that the range hood-compatible microwave oven blocks the user's field of view when using the cooktop, and the problem that the cooking area of the cooktop becomes narrow can arise. SUMMARY

[0179] In addition, the main body 10 may also include a rear plate 15. The rear plate 15 may be disposed on the rear side of the cavity 11. This rear plate 15 may form the back of the cooking device and cover the cavity 11 on the rear side.

[0180] The rear plate 15 can be integrally formed with the housing 13 or it can be formed separately from the housing 13.

[0181] A rotatable door 20 is provided in front of the main body 10 to selectively open and close the cooking chamber 10a. The door 20 can open and close the cooking chamber 10a in a side-swing manner, rotating left and right with the side as the center.

[0182] The door 20 can be a hexahedron with a specified thickness. A hinge can be provided between the main body 10 and the door 20. The hinge can be positioned on one side of the main body 10, allowing the side of the door 20 to be rotatably attached to the main body 10. The door 20 can be rotatably attached to the hinge on the front of the main body 10, and the cooking chamber 10a can be opened and closed by rotating around the hinge.

[0183] In addition, a cooking chamber heat source for heating the interior of the cooking chamber 10a is provided inside the main body 10. The cooking chamber heat source can be one type or more types.

[0184] In this embodiment, a case is illustrated where the heat source for the cooking chamber includes a magnetron capable of supplying a high-frequency heat source to the interior of the cooking chamber 10a. In this case, the magnetron may be disposed inside the main body 10 and positioned at the upper part or side of the cooking chamber 10a.

[0185] Furthermore, electrical chambers 10b, 10c, and 10d can be formed inside the main body 10, and these electrical chambers 10b, 10c, and 10d are located above or to the side of the cooking chamber 10a within the main body 10. In this embodiment, the magnetron and electrical chambers 10b, 10c, and 10d are arranged on the side of the cooking chamber 10a. Electrical components such as magnetrons and high-voltage transformers can be installed inside the electrical chambers 10b, 10c, and 10d.

[0186] Furthermore, a control panel 25 may be provided on the front side of the main body 10. As an example, the control panel 25 may be configured on the door 20.

[0187] The control panel 25 can be formed in the shape of a hexahedron with a defined internal space. An input section can be provided on the front of the control panel 25 for the user to input operation signals to operate the cooking equipment. Multiple operation switches can be provided in the input section, allowing the user to directly input operation signals.

[0188] As another example, the control panel 25 can also be configured on the front side of the cavity 11. This control panel 25 can be configured in an area that does not overlap with the cooking chamber 10a in the front-back direction. For example, electrical chambers 10b, 10c, and 10d can be configured on the side of the cooking chamber 10a, and the control panel 25 can be configured on the front side of the electrical chambers 10b, 10c, and 10d.

[0189] Furthermore, the cooking device of this embodiment may also include air supply units 100 and 200. Additionally, the main body 10 may be provided with an air intake 1 and exhaust ports 2, 3, and 4.

[0190] The air supply units 100 and 200 can be housed inside the cooking equipment and can draw in cooking gas through the air intake 1 and discharge the drawn-in cooking gas to the outside of the cooking equipment through the exhaust ports 2, 3 and 4.

[0191] [Intake port, exhaust port, internal compartment]

[0192] Figure 35 and Figure 36 It means from Figure 36-38 A three-dimensional view of the back of a cooking appliance with the back panel removed. Figure 39 yes Figure 40 Rear view of the cooking equipment.

[0193] Reference Figure 41 The air intake 1 can be disposed on the bottom surface of the cooking device. As an example, the air intake 1 can be disposed on the base plate 14. This air intake 1 can form a passage at the lower end of the cooking device for cooking gas to flow into the interior of the cooking device. In this embodiment, a pair of air intakes 1 are shown disposed on the lower side of the air supply sections 100 and 200.

[0194] The base plate 14 can be configured to be spaced downwards from the bottom surface of the cavity 11 by a predetermined interval. Thus, a lower space (notation omitted) can be formed between the bottom surface of the cavity 11 and the base plate 14. This lower space provides the necessary space for external air to flow into the interior of the cooking appliance through the air intake 1, located above the air intake 1.

[0195] Exhaust ports 2, 3, and 4 can be configured on the upper side of the cooking device. These exhaust ports 2, 3, and 4 can form a passage on the upper part of the cooking device for discharging cooking gases drawn into the cooking device to the outside of the cooking device.

[0196] In this embodiment, a case is illustrated where the cooking device is provided with a first exhaust port 2, a second exhaust port 3, and a third exhaust port 4.

[0197] The first exhaust port 2 and the second exhaust port 3 can be disposed on the top surface of the main body 10. The first exhaust port 2 and the second exhaust port 3 can form a passage at the upper end of the cooking device for discharging cooking gases drawn into the cooking device to the outside of the cooking device.

[0198] As an example, the first exhaust port 2 and the second exhaust port 3 can be provided on the top surface of the housing 13. The first exhaust port 2 and the second exhaust port 3 can be formed to extend through the top surface of the housing 13 in the vertical direction.

[0199] The first exhaust port 2 can be located on the rear side of the main body 10. The second exhaust port 3 can be located on the front side of the main body 10. That is, the second exhaust port 3 can be located on the side adjacent to the door 20, and is positioned further forward than the first exhaust port 2.

[0200] The first exhaust port 2 can form a passage for discharging cooking gases drawn into the cooking equipment to the outside. Furthermore, the second exhaust port 3 can form a passage for discharging cooking gases drawn into the cooking equipment to the inside.

[0201] As an example, the first exhaust port 2 can be configured in an area that overlaps vertically with the upper storage cabinet located on the upper side of the cooking equipment. Furthermore, the second exhaust port 3 can be configured in a position that protrudes further forward than the upper storage cabinet.

[0202] Furthermore, the first exhaust port 2 can be positioned approximately at the center of the main body 10 in the lateral direction. Additionally, a plurality of second exhaust ports 3 can be arranged in the lateral direction on the front side of the main body 10.

[0203] As described above, the first exhaust port 2, located approximately at the center of the side of the main body 10, can be connected to an exhaust pipe connected to the outside. Furthermore, a plurality of second exhaust ports 3 arranged laterally can exhaust cooking gases towards the upper side of the cooking appliance from the front of the upper storage cabinet. In this case, the cooking gases can be exhausted through the second exhaust ports 3 in a filtered state within the cooking appliance.

[0204] Similar to the first exhaust port 2, the third exhaust port 4 can form a passage for discharging cooking gases drawn into the cooking equipment to the outside. The third exhaust port 4 can be configured to face the wall on which the cooking equipment is installed. This third exhaust port 4 can be connected to an exhaust pipe installed on the wall and connected to the outside.

[0205] The third exhaust port 4 can be disposed on the back of the cooking device and on the upper side of the air supply section 100, 200. As an example, the third exhaust port 4 can be disposed on the rear panel 15. This third exhaust port 4 can be formed in the rear panel 15 to extend through in the front-to-back direction.

[0206] A space can be formed inside the main body 10. This space can be disposed between the cavity 11 and the box 13.

[0207] The space portion can be divided into a side space portion 10e and a rear space portion 10f. The side space portions 10e can be respectively disposed on both sides of the cavity 11 in the lateral direction. And, the rear space portion 10f can be disposed on the rear side of the cavity 11.

[0208] For example, the side space 10e can be a space formed between the side of the cavity 11 and the side of the housing 13. Furthermore, the rear space 10f can be a space formed between the back of the cavity 11 and the rear panel 15.

[0209] The side space section 10e and the rear space section 10f can communicate with the lower space section. The side space section 10e and the rear space section 10f can be connected to the lower space section in the vertical direction or in the lateral direction. The air inlet 1 can communicate with the lower space section, and the side space section 10e and the rear space section 10f can communicate with the air inlet 1 through the lower space section.

[0210] Electrical compartments 10b, 10c, and 10d may be disposed on any of the side spaces 10e. In this embodiment, an example is shown where electrical compartments 10b, 10c, and 10d are disposed on the side space located behind the control panel 25.

[0211] Additionally, a space can be formed inside the main body 10, which is both the rear side and the side side of the cavity 11. This space can be called the rear space 10f, the side space 10e, or the electrical room 10b, 10c, or 10d.

[0212] For example, the space can be located inside the main body 10 in a rear corner portion. Hereinafter, the space located on the rear side of the electrical rooms 10b, 10c, and 10d will be referred to as corner space portion 10e. The rear space portion 10f and the side space portion 10e, more specifically, the rear space portion 10f and the electrical rooms 10b, 10c, and 10d can be connected through the corner space portion 10e.

[0213] The air supply units 100 and 200 can be disposed inside the main body 10. More specifically, the air supply units 100 and 200 can be disposed in the space, that is, the space between the cavity 11 and the housing 13. The air supply units 100 and 200 may include at least one fan assembly 100 and 200.

[0214] The fan assemblies 100 and 200 can generate airflow for drawing in cooking gases from outside the cooking device and expelling them from outside the cooking device. These fan assemblies 100 and 200 can draw in cooking gases into the main body 10 through the intake port 1 and expel the inflowing cooking gases through the exhaust ports 2, 3, and 4.

[0215] At least one of the fan assemblies 100 and 200 disposed in the air supply sections 100 and 200 can be disposed in the rear space section 10f. Thus, cooking gases flowing into the main body 10 through the air intake 1 can be discharged through the rear space section 10f and then through the first exhaust port 2 or the second exhaust port 3. The specific configuration structure of the fan assemblies 100 and 200 will be described later.

[0216] Furthermore, an upper space portion 10i may be provided inside the main body 10. The upper space portion 10i may be disposed on the upper side of the cavity 11.

[0217] For example, the upper space portion 10i can be formed between the top surface of the cavity 11 and the top surface of the box 13. This upper space portion 10i can be connected to the rear space portion 10f.

[0218] That is, the air flowing into the rear space 10f can be discharged to the outside of the cooking device through the upper space 10i and through the exhaust ports 2, 3, and 4. In addition, the air flowing into the side space 10e can also be discharged to the outside of the cooking device through the rear space 10f and the upper space 10i and through the exhaust ports 2, 3, and 4.

[0219] [Fan assembly]

[0220] Figure 42 It is separation Figure 41 The rear fan assembly is shown in a 3D view. Figure 33-35 It is separation Figure 37-39 The corner fan assembly is shown in a 3D view.

[0221] ReferenceFigure 39 and Figure 40 The air supply units 100 and 200 may include at least one fan assembly 100 or 200. As an example, the air supply units 100 and 200 may include a rear fan assembly 100.

[0222] The rear fan assembly 100 may include a fan housing 110, an impeller 120, and a fan motor.

[0223] The fan housing 110 can form the appearance of the rear fan assembly 100 and house the impeller 120 inside. A first intake port 112 can be formed on the side of the fan housing 110. The first intake port 112 can form a passage in the fan housing 110 for drawing air from outside the rear fan assembly 100 into the interior of the impeller 120.

[0224] In this embodiment, the fan housing 110 is illustrated as a horizontally placed cylindrical shape including open sides, and the open sides of the fan housing 110 can be provided as a first intake port 112.

[0225] An accommodating space for accommodating the impeller 120 can be formed inside the fan housing 110. Furthermore, the inner peripheral surface of the fan housing 110 facing the accommodating space can be formed as a curved surface surrounding the outer peripheral surface of the impeller 120.

[0226] The first discharge port 114 can be located on the upper side of the fan housing 110. The first discharge port 114 forms a passage for discharging air into the receiving space of the impeller 120 to the outside of the air supply section 100, 200.

[0227] The first discharge port 114 can be formed in a shape that extends through the fan housing 110 in the vertical direction. Thus, air that is drawn into the fan housing 110 in the lateral direction through the first intake port 112 can be discharged to the upper side of the fan housing 110 through the first discharge port 114.

[0228] The impeller 120 is configured to rotate about an axis extending in the lateral direction. Inside this impeller 120, there is a space for air drawn in through the side of the impeller 120 to flow in.

[0229] The impeller 120 can be connected to the rotating shaft of a fan motor. The rotating shaft of the fan motor is capable of rotating about an axis extending in the lateral direction, and the impeller 120 connected to the rotating shaft of the fan motor can rotate together with the rotating shaft of the fan motor about an axis extending in the lateral direction.

[0230] The rear fan assembly 100, configured in this way, can be disposed inside the main body 10, and in at least one of the rear space portion 10f and the corner space portion 10e. In this embodiment, the case where the rear fan assembly 100 is disposed in the rear space portion 10f is illustrated.

[0231] As an example, the rear fan assembly 100 can be configured to include a pair of impellers 120. This rear fan assembly 100 can be provided in a configuration where a fan motor is arranged between a pair of impellers 120 arranged in the lateral direction.

[0232] In the rear fan assembly 100, the fan motor can rotate a pair of impellers 120 disposed on both sides of it. Furthermore, each impeller 120 can be housed inside a pair of fan housings 110 disposed on both sides of the fan motor.

[0233] As described above, the rear fan assembly 100, which includes a fan motor, a pair of impellers 120 and a fan housing 110, can draw in air through a pair of first intake ports 112 respectively arranged on both sides of the rear fan assembly 100 in the lateral direction, and discharge air through a pair of first exhaust ports 114 arranged on the upper side of the rear fan assembly 100.

[0234] The rear fan assembly 100 can be provided in the form of a pair of impellers 120 and a fan housing 110 disposed on both sides of the fan motor. Hereinafter, the assembly of the impellers 120 and the fan housing 110 will be referred to as a "fan module". Accordingly, it can be said that each rear fan assembly 100 is provided in the form of a pair of fan modules connected to both sides of the fan motor.

[0235] The rear fan assembly 100 can be configured in the rear space 10f, that is, the space formed between the back of the cavity 11 and the rear plate 15. This rear fan assembly 100 can be configured in the space communicating with the air intake 1 and the exhaust ports 2, 3, 4, and can draw in air through the air intake 1 and expel air to the exhaust ports 2, 3, 4.

[0236] The air supply units 100 and 200 in this embodiment may include a plurality of fan assemblies 100 and 200 arranged in the lateral direction. As an example, such as... Figure 32 and Figure 36-40 As shown, the air supply units 100 and 200 may also include corner fan assemblies 200. The rear fan assembly 100 and the corner fan assembly 200 may be arranged in the lateral direction in the rear space 10f.

[0237] The corner fan assembly 200 can be configured such that a fan module is connected to the fan motor. As an example, the corner fan assembly 200 can be provided in a configuration where a fan module is connected to the underside of the fan motor.

[0238] In this corner fan assembly 200, the impeller 220 can rotate around the vertical axis. Furthermore, the second intake port 212 can be disposed on the lower side of the fan housing 210, and the second exhaust port 214 can be disposed on the side of the fan housing 210.

[0239] That is, the corner fan assembly 200 can be provided in a form that is roughly similar to the form in which half of the rear fan assembly 100 is vertically upright.

[0240] The rear fan assembly 100 and the corner fan assembly 200 can be configured together in the rear space 10f. As an example, the rear fan assembly 100 and the corner fan assembly 200 can be arranged in the lateral direction in the rear space 10f.

[0241] For example, the corner fan assembly 200 can be configured on the side adjacent to the electrical rooms 10b, 10c, 10d, and the rear fan assembly 100 can be configured on the side adjacent to the side space 10e on the opposite side.

[0242] At least a portion of the corner fan assembly 200 may be disposed in the corner space 10e. As an example, a large portion of the corner fan assembly 200 may be disposed in the corner space 10e, and the second intake 212 of the corner fan assembly 200 may also be disposed in the corner space 10e. The corner fan assembly 200 may be configured to be spaced apart from the rear fan assembly 100 in the lateral direction by a predetermined interval.

[0243] According to this embodiment, the air supply units 100 and 200 may include a rear fan assembly 100 and a corner fan assembly 200 instead of only including a plurality of rear fan assemblies 100.

[0244] As described above, by using both the rear fan assembly 100 and the corner fan assembly 200 in the air supply sections 100 and 200, the lateral length of the entire air supply section 100 and 200 can be reduced compared to the case where the air supply section 100 and 200 only includes a plurality of rear fan assemblies 100.

[0245] For example, the lateral length of an air supply section including a rear fan assembly 100 and a corner fan assembly 200 can be shorter than that of an air supply section including a pair of rear fan assemblies 100 arranged in the lateral direction.

[0246] The corner fan assembly 200 not only includes a portion of the fan module included in the rear fan assembly 100, but is also provided in a configuration that includes a fan module that is vertically upright. Therefore, the lateral length of the corner fan assembly 200 can only be very short compared to the rear fan assembly 100.

[0247] In view of this, it can be said that the air supply section 100, 200 of this embodiment, which includes such a corner fan assembly 200, is very small in size compared to the air supply section that only includes the rear fan assembly 100.

[0248] If this type of air supply unit 100, 200 is applied to a cooking device, the size of the cooking device, especially the lateral length of the cooking device, is reduced by the amount of space occupied by the air supply unit 100, 200.

[0249] Considering this, when the size of the cooking device is slightly small and it is not possible to configure a plurality of rear fan assemblies 100 inside the cooking device, it can be said that the air supply units 100, 200 of this embodiment are very suitable for use in such cooking devices.

[0250] Furthermore, in the corner fan assembly 200, the second intake port 212 can be disposed on the lower side of the fan housing 210. Thus, the second intake port 212 can be disposed at the lowest end of the corner fan assembly 200, and can be disposed at a position very close to the air intake port 1 disposed at the lower end of the cooking device.

[0251] Considering that the suction performance of the fan assembly relative to the output of the fan motor can be greatly improved as the distance between the second suction port 212 and the air intake port 1 approaches, it can be known that as the second suction port 212 of the corner fan assembly 200 approaches the air intake port 1, the suction performance of the corner fan assembly 200 can be greatly improved.

[0252] 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 can be largely offset by the performance improvement obtained by shortening the distance between the second intake port 212 and the intake port 1.

[0253] In view of this, it can be evaluated that the air supply units 100 and 200 of this embodiment not only provide cooking gas removal performance at a level comparable to or better than other types of air supply units, but also provide an effect that helps to miniaturize cooking equipment.

[0254] The cooking apparatus of this embodiment, including the air supply units 100 and 200 as described above, can maintain a compact size and provide improved cooking gas removal performance.

[0255] On the other hand, refer to Figure 41-42 The rear fan assembly 100 and the corner fan assembly 200 can be configured to overlap with the cavity 11 in the front-to-back direction. That is, the rear fan assembly 100 and the corner fan assembly 200 can be configured in the vertical direction between the top and bottom surfaces of the cavity 11.

[0256] In order to allow the air flowing into the interior of the main body 10 through the air intake 1 to move smoothly toward the rear fan assembly 100 or the corner fan assembly 200, a specified distance needs to be maintained between the rear fan assembly 100 and the corner fan assembly 200 and the air intake 1.

[0257] In addition, in order to allow the air expelled from the rear fan assembly 100 and the corner fan assembly 200 to move smoothly towards the upper space portion 10i, it is preferable that the rear fan assembly 100 and the corner fan assembly 200 are positioned at a lower position than the upper space portion 10i.

[0258] When the rear fan assembly 100 and the corner fan assembly 200 are positioned higher than the upper space portion 10i, the passage between the first discharge port 114 of the rear fan assembly 100 or the corner fan assembly 200 and the upper space portion 10i may be too narrow.

[0259] In view of this, in this embodiment, the rear fan assembly 100 and the corner fan assembly 200 are positioned such that the rear fan assembly 100 and the corner fan assembly 200 are appropriately separated from the air intake 1 and from the upper space portion 10i.

[0260] This allows for smooth airflow from the intake port 1 to the rear fan assembly 100 and the corner fan assembly 200, and smooth airflow from the rear fan assembly 100 and the corner fan assembly 200 to the upper space portion 10i.

[0261] Furthermore, the corner fan assembly 200 can be positioned closer to the air intake 1 than the exhaust ports 2, 3, and 4. Therefore, the second intake port 212 of the corner fan assembly 200 can be positioned very close to the air intake 1. This effectively improves the intake performance of the corner fan assembly 200, which is relatively small in size and output compared to the rear fan assembly 100.

[0262] [An example of a flow path forming component]

[0263] Figure 36-40 It is separation ​ The flow path forming component is shown in a rear perspective view. ​ This is a rear view showing the airflow state in the cooking apparatus of the first embodiment of the present invention.

[0264] Reference ​ as well as ​ The cooking apparatus may include a flow path forming member 30. The flow path forming member 30 is configured to guide the flow of air expelled from the air supply sections 100 and 200.

[0265] The flow path forming member 30 can form an exhaust flow path A inside the cooking appliance. The exhaust flow path A can connect the air supply sections 100 and 200 and the upper space section 10i, and can guide the airflow from either the rear fan assembly 100 or the corner fan assembly 200 to the upper space section 10i. This exhaust flow path A can direct the flow of air expelled from the air supply sections 100 and 200 to the exhaust ports 2, 3, and 4.

[0266] As an example, exhaust flow path A can be configured in the rear space portion 10f. The inlet of such exhaust flow path A can open toward the air supply portions 100 and 200. For example, the inlet of exhaust flow path A can open toward the first outlet 114 of the rear fan assembly 100 and the second outlet 214 of the corner fan assembly 200. Furthermore, the outlet of exhaust flow path A can open toward the upper space portion 10i.

[0267] The exhaust flow path A can be formed inside the cooking appliance to guide the airflow from the first exhaust port 114 of the rear fan assembly 100 to the upper space portion 10i. Alternatively, the exhaust flow path A can be formed inside the cooking appliance to guide the airflow from the second exhaust port 214 of the corner fan assembly 200 to the upper space portion 10i.

[0268] As an example, at least a portion of the exhaust flow path A may be formed by a first flow path plate 31. The first flow path plate 31 may form a wall that blocks the space between the first intake port 112 and the first exhaust port 114 of the rear fan assembly 100.

[0269] This first flow path plate 31 can be disposed in the rear space portion 10f and on the upper side of the rear fan assembly 100. That is, the first flow path plate 31 can form a wall on the upper side of the rear fan assembly 100 that blocks the space between the first intake port 112 and the first discharge port 114.

[0270] According to this embodiment, a rear fan assembly 100 and corner spaces 10g and 10h can be arranged in the rear space 10f along the lateral direction. In the rear space 10f, first intake ports 112 can be respectively disposed on both sides of the rear fan assembly 100 in the lateral direction. Furthermore, a first exhaust port 114 can be disposed between a pair of first intake ports 112 spaced apart in the lateral direction, and disposed on the top surface of the rear fan assembly 100.

[0271] If either of the pair of first intake ports 112 located closer to the corner spaces 10g, 10h is designated as the left first intake port 112, then the first flow path plate 31 is configured to form a wall that blocks the space between the first discharge port 114 and the right first intake port 112. This first flow path plate 31 can be positioned at a location offset from the center of the rear fan assembly 100 towards the right first intake port 112, i.e., adjacent to the right first intake port 112.

[0272] Hereinafter, the direction from the side of the cooking equipment toward the center along the side toward the electrical compartments 10b, 10c, and 10d will be referred to as the left side, and the direction toward the side space 10e located on the opposite side will be referred to as the right side.

[0273] The first flow path plate 31 can form a longitudinal wall extending upward from the top surface of the rear fan assembly 100 where the first discharge port 114 is formed, towards the upper space portion 10i. This first flow path plate 31 can define the right boundary surface of the exhaust flow path A.

[0274] On the other hand, the cooking device of this embodiment may also include an expansion plate 18. The expansion plate 18 may be configured to block the space between the upper space 10i and the rear space 10f.

[0275] At least a portion of the expansion plate 18 may be disposed in the rear space portion 10f. At least a portion 18b of the expansion plate 18 disposed in this location (hereinafter referred to as the "rear partition") may be disposed vertically between the rear fan assembly 100 and the upper space portion 10i. In addition, the rear partition 18b of the expansion plate 18 may be disposed in the front-rear direction between the back of the cavity 11 and the rear panel 15.

[0276] The rear partition 18b of the expansion plate 18 configured in this way covers a portion of the rear space 10f at a position higher than the rear fan assembly 100, and blocks the space between a portion of the rear space 10f and the upper space 10i.

[0277] In this embodiment, a case is illustrated where the right side region of the rear space 10f and the upper space 10i are laterally blocked by the expansion plate 18.

[0278] The expansion plate 18 and the rear fan assembly 100 are spaced apart vertically, thereby forming a lateral passage between the expansion plate 18 and the rear fan assembly 100. This lateral passage connects the right-side region of the rear space 10f covered by the expansion plate 18 with the upper region of the rear fan assembly 100, where the exhaust flow path A is formed.

[0279] The first flow path 31 may form a longitudinal wall extending upward from the rear fan assembly 100 toward the expansion plate 18. As an example, the first flow path 31 may form a longitudinal wall connecting the top surface of the rear fan assembly 100 and the side end of the expansion plate 18. At least a portion of such the first flow path 31 may protrude upward toward the expansion plate 18.

[0280] As described above, the first flow path plate 31 connected to the expansion plate 18 can form a longitudinal wall that blocks the lateral passage formed between the rear fan assembly 100 and the expansion plate 18. That is, the first flow path plate 31 can form a wall in the rear space 10f that blocks the airflow between the right side region in the rear space 10f and the exhaust flow path A.

[0281] Additionally, the flow path forming member 30 may also include a second flow path plate 32. The second flow path plate 32 may form a wall that blocks the space between the first intake port 112 and the first discharge port 114 of the rear fan assembly 100.

[0282] The second flow path board 32 can be disposed on the left side of the rear fan assembly 100. Accordingly, in the lateral direction, the rear fan assembly 100 can be disposed between the first flow path board 31 and the second flow path board 32.

[0283] In the lateral direction, a second flow path 32 can be disposed between the rear fan assembly 100 and the corner fan assembly 200. This second flow path 32 can form a wall that blocks the space between the first intake port 112 and the first discharge port 114, while also forming a wall that blocks the space between the second discharge port 214 of the corner fan assembly 200 and the first intake port 112 of the rear fan assembly 100.

[0284] In the corner fan assembly 200, the second intake port 212 faces the intake port 1, i.e., is positioned below. Furthermore, the second exhaust port 214 can face the rear fan assembly 100, i.e., to the side, more specifically to the right, and is connected to the exhaust flow path A.

[0285] The second flow path plate 32 can be disposed on the right side of the second discharge port 214 and define the lower boundary surface of the exhaust flow path A. This second flow path plate 32 can define the lower boundary surface of the exhaust flow path A between the rear fan assembly 100 and the corner fan assembly 200. At this time, the lower boundary surface of the exhaust flow path A defined by the second flow path plate 32 can form an inclined surface whose height changes along the lateral direction.

[0286] According to this embodiment, the second discharge port 214 can be configured to face the first intake port 112 configured toward the corner fan assembly 200. Furthermore, the first discharge port 114 can be configured at a position higher than the first intake port 112 and higher than the second discharge port 214.

[0287] As an example, the second flow path plate 32 may form an inclined surface extending laterally from the lower side of the second discharge port 214 toward the upper side of the first suction port 112. For example, the second flow path plate 32 may extend laterally and upward toward the rear fan assembly 100 from one side adjacent to the corner fan assembly 200.

[0288] One side end of the second flow path plate 32 can be disposed below the second discharge port 214. For example, the left end of the second flow path plate 32 can be disposed at a position lower than the second discharge port 214.

[0289] Additionally, the other end of the second flow path plate 32 in the lateral direction can be disposed above the first suction port 112. For example, the right end of the second flow path plate 32 can be disposed at a position higher than the first suction port 112.

[0290] The second flow path plate 32 can form an inclined wall that blocks the space between the first intake port 112 and the first discharge port 114, and between the first intake port 112 and the second discharge port 214. That is, the second flow path plate 32 can form an inclined wall between the rear fan assembly 100 and the corner fan assembly 200, which can block not only the space between the first intake port 112 and the first discharge port 114, but also the space between the first intake port 112 and the second discharge port 214.

[0291] Therefore, between the rear fan assembly 100 and the corner fan assembly 200, the air discharged from the first discharge port 114 will not flow into the first intake port 112, and the air discharged through the second discharge port 214 will not flow into the first intake port 112.

[0292] That is, the second flow path plate 32 can form a wall between the rear fan assembly 100 and the corner fan assembly 200 to block the airflow from the first discharge port 114 and the second discharge port 214 to the first intake port 112.

[0293] According to this embodiment, an exhaust flow path A can be formed on the left side of the first flow path plate 31 and the upper side of the second flow path plate 32. An intake port 1 can be disposed below the exhaust flow path A. Furthermore, in the vertical direction, a first intake port 112 and a second intake port 212 can be disposed between the intake port 1 and the exhaust flow path A, and a first discharge port 114 and a second discharge port 214 can be disposed between the exhaust flow path A and the upper space portion 10i.

[0294] The first outlet 114 and the second outlet 214 can be connected to the exhaust flow path A. The first outlet 114 can be configured upwards and connected to the exhaust flow path A. In addition, the second outlet 214 can be configured sideways and connected to the exhaust flow path A.

[0295] In addition, the second flow path plate 32 can also form a flow path to guide the air inflow to the first intake port 112.

[0296] As an example, the second flow path plate 32 can be disposed above the air intake 1, and on the left and upper sides of the first intake 112. This second flow path plate 32 can form the left and upper boundary surfaces of the flow path connecting the air intake 1 and the first intake 112. With the second flow path plate 32 thus configured, air flowing from the left side of the rear fan assembly 100 towards the first intake 112 can be effectively guided.

[0297] On the other hand, the flow path forming member 30 may also include a fastening plate 33. The fastening plate 33 may be disposed on the rear fan assembly 100.

[0298] As an example, the fastening plate 33 allows the first discharge port 114 to open upwards and engage with the top surface of the rear fan assembly 100. This fastening plate 33 can be positioned above the first intake port 112, or higher than the second intake port 212 and the second discharge port 214.

[0299] According to this embodiment, the first flow path plate 31 can be provided in a form that extends upward from the fastening plate 33. Furthermore, the second flow path plate 32 can be provided in a form that extends downward from the fastening plate 33. That is, the upper end of the second flow path plate 32 can be connected to the fastening plate 33.

[0300] As described above, the first flow path plate 31 and the second flow path plate 32, which are connected to the fastening plate 33, can be combined with the rear fan assembly 100 via the fastening plate 33.

[0301] Additionally, the fastening plate 33 can be disposed between the first flow path plate 31 and the second flow path plate 32 and connect the first flow path plate 31 and the second flow path plate 32. As an example, the flow path forming member 30 can 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.

[0302] According to the flow path forming member 30 provided in this form, the first flow path plate 31 and the second flow path plate 32 do not need to be separately combined with the rear fan assembly 100. The first flow path plate 31 and the second flow path plate 32 can be set up simply and quickly by means of the fastening plate 33 combined with the rear fan assembly 100.

[0303] A discharge port (notation omitted) may be formed in the fastening plate 33. The first discharge port 114 can be exposed to the upper side of the fastening plate 33, i.e., the interior of the exhaust flow path A, through the discharge port.

[0304] Additionally, the cooking apparatus of this embodiment may also include a support member 40. The support member 40 is configured to support the corner fan assembly 200. At least a portion of this support member 40 may be disposed in the corner spaces 10g and 10h.

[0305] As an example, the support member 40 may also include a side support portion 41. The side support portion 41 may be disposed on the side of the corner fan assembly 200. The side support portion 41 may form the side surface of the support member 40, and more specifically, may form the right side surface of the support member 40.

[0306] The side support portion 41 can be formed as a longitudinal wall covering the corner fan assembly 200 on the side. For example, the side support portion 41 can be formed as a longitudinal plane orthogonal to the lateral axis. This side support portion 41 can also form a wall in the rear space portion 10f that blocks the space between the corner fan assembly 200 and the rear fan assembly 100.

[0307] The side support 41 can be configured between the corner fan assembly 200 and the second flow path plate 32. This side support 41 can define the left boundary surface of the exhaust flow path A.

[0308] An outlet hole (notation omitted) may be formed in the side support portion 41. The second outlet 214 may be exposed to the right side of the side support portion 41, i.e., the interior of the exhaust flow path A, through this outlet hole.

[0309] Furthermore, the cooking apparatus of this embodiment may also include connecting flow path forming members 37 and 38. The connecting flow path forming members 37 and 38 may be disposed on the upper side of the corner fan assembly 200. These connecting flow path forming members 37 and 38 divide the rear space portion 10f, such that a portion of the area surrounding the support member 40 in the rear space portion 10f is separated as the connecting flow path portion 39.

[0310] As an example, the connecting flow path forming components 37 and 38 may include a first partition 37 and a second partition 38.

[0311] The first partition 37 can be formed as a longitudinal wall configured to be spaced apart from the side of the support member 40 by a predetermined interval. As an example, the first partition 37 can be formed as a longitudinal wall spaced apart from the side of the side support 41 by a predetermined interval. In the lateral direction, the first partition 37 can be configured between the corner fan assembly 200 and the rear fan assembly 100.

[0312] The second partition 38 can form a wall connecting the side support 41 and the first partition 37. As an example, the first partition 37 can be positioned at a predetermined interval to the right from the side support 41. The second partition 38 can form a wall connecting the lower end of the first partition 37 and the side support 41.

[0313] As an example, the second partition 38 can be disposed on the upper side of the second flow path plate 32. The left end of this second partition 38 can be combined with the side support 41. In addition, the left end of the second partition 38 can be configured to be separated from the left end of the second flow path plate 32 in the vertical direction through the second discharge port 214.

[0314] As an example, the second partition 38 can be formed as an inclined surface parallel to the second flow path plate 32. This second partition 38, together with the side support 41, can define the left boundary surface of the exhaust flow path A and guide the flow of air discharged from the second outlet 214 to the exhaust flow path A towards the central side of the exhaust flow path A.

[0315] The first partition 37 can extend upward from the second partition 38 and, together with the side support 41 and the second partition 38, define the left boundary surface of the exhaust flow path A. This first partition 37 can direct the flow of air flowing in the exhaust flow path A towards the upper space 10i.

[0316] If the air supply unit starts operating at 100 or 200, then as follows ​ as well as ​ As shown, an intake airflow can be formed to draw air from outside the cooking device into the cooking device. The intake airflow thus formed acts on the external air that is being drawn in through the air inlet 1 located at the lower end of the cooking device. The external air around the air inlet 1, i.e., the cooking gas, can be drawn into the body 10 through the air inlet 1 by the intake airflow that performs this function.

[0317] Furthermore, the cooking gas drawn into the main body 10 can flow into the rear space 10f within the space of the main body 10. The cooking gas flowing into the rear space 10f can be drawn into the rear fan assembly 100 and the corner fan assembly 200 respectively through the first intake ports 112 disposed on both sides of the rear fan assembly 100 and the intake port disposed on the lower side of the corner fan assembly 200.

[0318] At this time, the air intake into the rear fan assembly 100 can be guided by at least a portion of the flow path forming member 30. Specifically, the air intake into the first intake port 112 located on the left side of the rear fan assembly 100 can be guided by the second flow path plate 32.

[0319] Air drawn into the rear fan assembly 100 and the corner fan assembly 200 can be discharged through the first discharge port 114 and the second discharge port 214, respectively. The flow of the discharged air can be guided by the exhaust flow path A.

[0320] Air discharged from the second outlet 214 of the corner fan assembly 200 can flow through the rear space 10f and upward to the upper space 10i via the exhaust flow path A. Around the second outlet 214, the exhaust flow path A can form a passage that slopes upward to the right from the second outlet 214.

[0321] The upward-right shaped passage thus formed reduces resistance to airflow in the exhaust flow path A, minimizing flow loss inside the cooking device. This upward-right shaped passage can be formed by a second flow path plate 32 that defines the lower boundary of the exhaust flow path A on the right side of the second discharge port 214 and connecting flow path forming members 37 and 38 that define the left boundary of the flow path.

[0322] Additionally, the air discharged from the first outlet 114 of the rear fan assembly 100 can flow through the exhaust flow path A and through the rear space 10f to the upper space 10i. At this time, the exhaust flow path A can guide the air flow so that the air discharged through the first outlet 114 can flow to the upper space 10i without spreading to the surrounding area.

[0323] [Air intake and air exhaust structure of cooking equipment]

[0324] ​ This is a rear perspective view showing the first state of the cooking device according to the first embodiment of the present invention. ​ It means ​ A diagram showing the airflow patterns within the cooking equipment. Additionally... ​ This is a rear perspective view showing the second state of the cooking apparatus according to the first embodiment of the present invention. ​ It means ​ A diagram showing the airflow patterns within the cooking equipment. Additionally... ​ This is a rear perspective view showing the third state of the cooking apparatus according to the first embodiment of the present invention. ​ It means ​ A diagram showing the airflow patterns within a cooking appliance.

[0325] The following is for reference ​ The air intake and air exhaust structures in the cooking apparatus of this embodiment will be described.

[0326] Reference ​ An air intake 1 can be provided at the lower end of the cooking device, and an exhaust vent can be provided at the upper end of the cooking device. A first exhaust vent 2 can be located on the top surface of the housing 13, positioned towards the rear of the cooking device, and a second exhaust vent 3 can be located towards the front of the cooking device. Furthermore, a third exhaust vent 4 can be located at the rear of the cooking device and is positioned on the rear panel 15.

[0327] The air supply units 100 and 200 may include a rear fan assembly 100 and a corner fan assembly 200, wherein the rear fan assembly 100 may be configured in the rear space 10f. In addition, the corner fan assembly 200 may be configured in the rear space 10f or the corner space 10g or 10h.

[0328] When the rear fan assembly 100 and the corner fan assembly 200 begin to operate, an intake airflow is formed to draw air from outside the cooking appliance into the appliance. This intake airflow acts on the outside air through the air intake 1 located at the lower end of the cooking appliance. The outside air around the air intake 1, i.e., the cooking gas, can be drawn into the main body 10 through the air intake 1 using this intake airflow.

[0329] Furthermore, cooking gases drawn into the main body 10 can flow into the rear space 10f through the lower space. For example, cooking gases flowing into the lower space can flow into the rear space 10f and the corner spaces 10g and 10h.

[0330] Cooking gas flowing into the rear space 10f can be drawn into the interior of the rear fan assembly 100 through the first intake ports 112 respectively arranged on both sides of the rear fan assembly 100. The cooking gas drawn into the rear fan assembly 100 can then be discharged upward through the first exhaust port 114 arranged on the upper side of the rear fan assembly 100.

[0331] Cooking gas flowing into the corner space (10g, 10h) can be drawn into the interior of the corner fan assembly 200 through the second intake port 212 located on the lower side of the corner fan assembly 200. The cooking gas drawn into the corner fan assembly 200 can then be discharged to the side of the corner fan assembly 200 through the second discharge port 214 located on the side of the corner fan assembly 200.

[0332] The rear space 10f can connect the air intake 1 located on the lower side of the lower space and the upper space 10i. Furthermore, an exhaust flow path A can be formed in this rear space 10f. The flow of cooking gases expelled from the rear fan assembly 100 and the corner fan assembly 200 can be directed to the upper space 10i by the exhaust flow path A.

[0333] When the first exhaust port 2 is open while the second exhaust port 3 and the third exhaust port 4 are blocked (hereinafter referred to as the "first state of the cooking equipment"), the cooking gas flowing upward through the exhaust flow path A can be discharged to the outside through the first exhaust port 2.

[0334] As an example, the first exhaust port 2 can be connected to a pipe (not shown) connected to the outside. For example, a pipe can be provided on the top surface of the main body 10, and the internal space of the pipe can be connected to the first exhaust port 2.

[0335] This first exhaust port 2, which is connected to the pipe, can form a passage connecting the upper space 10i to the outside of the cooking device. This first exhaust port 2 can be configured on the upper side of the upper space 10i and at a position that overlaps with the rear space 10f in the vertical direction.

[0336] That is, the rear fan assembly 100, the rear space portion 10f, and the first exhaust port 2 can be arranged in a position that overlaps in the vertical direction. Preferably, the rear fan assembly 100, the rear space portion 10f, and the first exhaust port 2 can be arranged in a row along the vertical direction.

[0337] Furthermore, the exhaust flow path A can be disposed in the rear space 10f between the air supply sections 100 and 200 and the first exhaust port 2. The inlet of this exhaust flow path A can open towards the air supply sections 100 and 200, and the outlet of the exhaust flow path A can open towards the upper space 10i. Moreover, the first exhaust port 2 can be disposed in an area that overlaps with the outlet of the exhaust flow path A in the vertical direction.

[0338] Therefore, the airflow generated by the operation of the rear fan assembly 100 can be formed in a straight line direction that is the same as the arrangement direction of the rear fan assembly 100, the rear space portion 10f and the first exhaust port 2.

[0339] If the airflow is formed in this straight direction, the resistance to the airflow can be reduced accordingly, allowing for smoother airflow. Therefore, the air intake and exhaust performance of the rear fan assembly 100 can be improved, thereby correspondingly improving the cooking gas removal performance of the cooking equipment.

[0340] On the other hand, such as ​ and ​ As shown, the cooking device in this embodiment can also exhaust cooking gases drawn into the cooking device into the room. At this time, the cooking device can be in a state where only the second exhaust port 3 of exhaust ports 2, 3, and 4 is open while the first exhaust port 2 and the third exhaust port 4 are blocked (hereinafter referred to as the "second state of the cooking device").

[0341] In the second state of the cooking device, the second exhaust port 3 provides a passage for discharging the cooking gas drawn into the cooking device into the room. That is, the cooking gas that flows into the rear space 10f through the air intake 1 can be discharged into the room through the second exhaust port 3 after passing through the upper space 10i.

[0342] As an example, a filter (not shown) can be installed on the bottom surface of the cooking device. The filter can be configured at the air intake 1, and the cooking gases can be filtered by the filter as they pass through the air intake 1.

[0343] As another example, a filter may also be provided in the upper space 10i. For example, the filter may be provided inside the main body 10 and in the second exhaust port 3. In this case, cooking gases flowing from the rear space 10f to the upper space 10i can pass through the filter and be discharged into the room through the second exhaust port 3 in a filtered state.

[0344] like ​ and ​ As shown, the cooking device in this embodiment can exhaust the cooking gas drawn into the cooking device to the outside through the third exhaust port 4.

[0345] At this time, the cooking device can be in a state where only the third exhaust port 4 among the exhaust ports 2, 3, and 4 is open, while the first exhaust port 2 and the second exhaust port 3 are blocked (hereinafter referred to as the "third state of the cooking device").

[0346] As an example, the third exhaust port 4 can be connected to a pipe or conduit Da (see reference) embedded in the wall where the cooking equipment is installed. ​ Connection. For example, a pipe or conduit Da may be incorporated into the rear panel 15, and the internal space of the pipe or conduit Da may be connected to the third exhaust port 4.

[0347] The third exhaust port 4, which is connected to the piping or ductwork, is positioned closest to the air supply units 100 and 200. Therefore, in the third state of the cooking equipment, the distance between the air supply units 100 and 200 and the exhaust ports 2, 3, and 4 can be minimized. Furthermore, since the third exhaust port 4 is located on the back of the cooking equipment facing the wall, the third exhaust port 4 and the piping or ductwork will not be exposed to the outside.

[0348] That is, in the third state of cooking equipment, the cooking equipment can reduce the flow resistance inside the cooking equipment by reducing the air flow distance inside the cooking equipment, and keep the appearance of the cooking equipment simple and clean.

[0349] As described above, in the cooking apparatus of this embodiment with the air supply units 100 and 200 arranged in the rear space 10f, the flow of air related to the intake of cooking gas and the discharge through the first exhaust port 2 is formed in a straight line, thereby minimizing the flow loss inside the cooking apparatus and further improving the cooking gas removal performance.

[0350] Furthermore, in the cooking apparatus of this embodiment, the upper space 10i can effectively ensure the space for the filter, thereby not only maintaining a compact size but also having the effect of smoothly filtering cooking gases and venting them into the room.

[0351] On the other hand, as described above, the space inside the main body 10 can be divided into a side space 10e, a rear space 10f, and an upper space 10i. In this embodiment, the air supply units 100 and 200 are disposed in the rear space 10f, rather than the side space 10e or the upper space 10i.

[0352] Typically, the lateral length of the side space 10e without an electrical compartment is less than the longitudinal length of the rear space 10f. That is, the side space 10e can provide only a narrower space compared to the rear space 10f.

[0353] Depending on the type of cooking equipment, various devices can be installed in the rear space section 10f. For example, in the case of a cooking equipment that provides convection function, a convection module can be installed in the rear space section 10f.

[0354] In contrast, the side space 10e, where electrical compartments 10b, 10c, and 10d are not formed, rarely contains additional devices. Therefore, there is no need to unnecessarily increase the lateral width of the side space 10e. If the lateral length of the side space 10e is unnecessarily increased, the overall size of the cooking equipment will increase regardless of whether the performance of the cooking equipment is improved.

[0355] With this in mind, the side space portion 10e is preferably formed to provide a smaller space than the rear space portion 10f.

[0356] To reduce costs, cooking appliances with the same cooking chamber volume typically share the same body 10. For example, a cooking appliance that has both high-frequency and convection functions can be manufactured using the same body 10 as a cooking appliance that only has high-frequency functions.

[0357] Therefore, the main body 10 of this embodiment may include a rear space portion 10f that provides space suitable for configuring the convection module, and the side space portion 10e may be formed in a form that provides only a smaller space than the rear space portion 10f.

[0358] In view of this, the air supply units 100 and 200 of this embodiment can be configured in the rear space 10f, which provides more space than the side space 10e. As described above, by configuring the air supply units 100 and 200 in the rear space 10f, not only can the flow loss inside the cooking device be reduced, but also larger and higher-performance fan assemblies can be applied to the air supply units 100 and 200.

[0359] That is, the cooking device of this embodiment, including the air supply units 100 and 200 disposed in the rear space 10f, can provide higher cooking gas removal performance while suppressing the increase in size of the cooking device using the body 10 of commonly used specifications.

[0360] [Supporting Components]

[0361] ​ This is a magnified view showing the corner fan assembly and its surroundings. ​ It is separation ​ The supporting components are shown in a rear perspective view. Additionally, ​ This is a rear perspective view of a portion of a cooking appliance, showing another example of the application of support components. ​ It is separation ​ The supporting components are shown in a three-dimensional view of the rear.

[0362] Reference ​ , ​ as well as ​ The cooking apparatus of this embodiment may include a support member 40. The support member 40 may support the corner fan assembly 200, so that the flow of air discharged from the second outlet 214 can be guided to the rear space portion 10f side.

[0363] At least a portion of the support member 40 can form a wall that blocks the space between the side space 10e and the rear space 10f. That is, at least a portion of the support member 40 can form a wall in the rear space 10f that blocks the space between the corner fan assembly 200 and the rear fan assembly 100.

[0364] The support member 40 can form a wall that divides the rear space 10f into two regions along the lateral direction. As an example, the support member 40 can divide a portion of the rear space 10f adjacent to the side space 10e into corner spaces 10g and 10h. Additionally, at least a portion of the support member 40 can be formed as a wall covering the corner fan assembly 200 on the side. This wall can be formed by a side support 41.

[0365] The second outlet 214 can be disposed on the side of the corner fan assembly 200, facing the support member 40, and more specifically, the side support portion 41. Furthermore, an outlet hole 41a can be formed in the side support portion 41. The outlet hole 41a allows the second outlet 214 to be exposed to the side and is formed to penetrate the side support portion 41 in a lateral direction.

[0366] The side support 41 can be combined with the corner fan assembly 200. That is, the corner fan assembly 200 can be combined with the side support 41 in the lateral direction and supported by the support member 40.

[0367] The support member 40 may include a front support portion 42. The front support portion 42 may form the front of the support member 40 and be disposed on the front side of the corner fan assembly 200.

[0368] The front support portion 42 can be formed as a longitudinal wall covering the front corner fan assembly 200. For example, the front support portion 42 can be formed as a longitudinal plane orthogonal to the front-rear axis. This front support portion 42 can be configured in the cooling fan 6 described later (see figure). ​ The wall between the cooling fan 6 and the corner fan assembly 200 is formed in the electrical chambers 10b, 10c, and 10d.

[0369] The front support portion 42 can be connected to the side support portion 41 on the side side. As an example, the right end of the front support portion 42 can be connected to the front end of the side support portion 41. For example, the front support portion 42 and the side support portion 41 can be connected in an "L" shape.

[0370] As described above, the front support 42, which is connected to the side support 41, can support the side support 41 from the front. This front support 42 can function as a shielding wall that blocks the space between the cooling fan 6 and the corner fan assembly 200, and as a support wall that supports the side support 41 that supports the corner fan assembly 200.

[0371] Alternatively, the front support portion 42 may also include a support surface forming a longitudinal plane for connection with electrical components. For example, electrical components such as magnetrons, high-voltage transformers, high-voltage capacitors, and noise filters may be disposed in electrical compartments 10b, 10c, and 10d, and at least one of these electrical components may be disposed on the support surface of the front support portion 42. In this embodiment, a case in which a high-voltage capacitor is disposed on the support surface of the front support portion 42 is illustrated.

[0372] Furthermore, the support member 40 may also include an upper support portion 43. The upper support portion 43 may form the top surface of the support member 40 and be disposed on the upper side of the corner fan assembly 200. As an example, the upper support portion 43 may be disposed in the corner spaces 10g and 10h.

[0373] The upper support portion 43 may be disposed above the side support portion 41 and the front support portion 42, and connected to at least one of the side support portion 41 and the front support portion 42 in the vertical direction. In this embodiment, the case where the upper support portion 43 is connected to both the side support portion 41 and the front support portion 42 is illustrated.

[0374] As an example, the front end of the upper support 43 can be connected to the upper end of the front support 42, and the right end of the upper support 43 can be connected to the upper end of the side support 41. Through the upper support 43, the three surfaces of the support member 40 can be connected into a whole, thereby improving the structural stability of the support member 40.

[0375] Alternatively, the upper support portion 43 may also include a support surface forming a transverse plane for connection with electrical components. In this embodiment, an example is shown where a noise filter connected to a corner fan assembly is disposed on the support surface of the upper support portion 43.

[0376] The support member 40, including the side support 41, front support 42 and upper support 43 as described above, can not only provide a shielding wall between the cooling fan 6 and the corner fan assembly 200, but also provide a support wall for the stable installation of electrical components and the corner fan assembly 200.

[0377] As an example, the support member 40 can be provided as a single integrally formed side support 41, front support 42, and upper support 43. This type of support member 40 facilitates assembly and installation, component management, and also provides excellent structural stability.

[0378] [Structure of the Electrical Room]

[0379] ​ This diagram illustrates the flow of outside air into the electrical room through the cold air inlet. ​ It is a diagram showing the airflow pattern as it enters the electrical room. ​ This diagram illustrates the flow pattern of air flowing from the upper corner space into the lower corner space via the connecting flow path.

[0380] Reference ​ and ​ A cold air inlet 5 may be provided on the main body 10. The cold air inlet 5 may be arranged together with the first exhaust port 2 and the second exhaust port 3 on the top surface of the main body 10.

[0381] As an example, the cold air inlet 5 can be formed on the top surface of the housing 13 to extend vertically. This cold air inlet 5 can be positioned above the electrical chambers 10b, 10c, and 10d, opening them to the outside of the main body 10. Outside air can flow into the electrical chambers 10b, 10c, and 10d through the cold air inlet 5.

[0382] Reference ​The cooking apparatus of this embodiment may include a partition plate 50. The partition plate 50 may be disposed in the side space portion 10e, and more specifically in the electrical compartments 10b, 10c, and 10d.

[0383] As an example, the partition 50 can form a transverse plane orthogonal to the vertical axis. This partition 50 can divide the side space 10e vertically and can be divided into a lower electrical compartment 10b and an upper electrical compartment 10c. For example, electrical compartments 10b, 10c, and 10d can be divided into a lower electrical compartment 10b on the lower side of the partition 50 and an upper electrical compartment 10c on the upper side of the partition 50.

[0384] As an example, in electrical rooms 10b, 10c, and 10d, the lower electrical room 10b occupies a much larger space compared to the upper electrical room 10c. For instance, the vertical length of the lower electrical room 10b can be much greater than that of the upper electrical room 10c. Most electrical components, including magnetrons, high-voltage transformers, and high-voltage capacitors, can be primarily located in the lower electrical room 10b.

[0385] The cooking apparatus of this embodiment may also include a cooling fan 6. The cooling fan 6 is configured to allow outside air to flow into the electrical chambers 10b, 10c, and 10d through the cold air inlet 5. As an example, the cooling fan 6 may be configured together with most of the electrical components in the lower electrical chamber 10b.

[0386] The air supply units 100 and 200 can be arranged on the rear side of the cooling fan 6, and a support member 40 can be arranged between the cooling fan 6 and the corner fan assembly 200, or more specifically, a front support unit 42 can be arranged.

[0387] The cooling fan 6 can generate airflow to allow outside air to flow into the interior of the main body 10 through the cold airflow inlet 5.

[0388] When the cooling fan 6 is activated, outside air can flow into the upper electrical chamber 10c through the cold air inlet 5. The air flowing into the upper electrical chamber 10c can flow into the lower electrical chamber 10b through the partition plate 50.

[0389] Therefore, through holes 52 and 54 can be provided in the partition plate 50. Through holes 52 and 54 can form a passage connecting the upper electrical chamber 10c and the lower electrical chamber 10b in the partition plate 50. As an example, through holes 52 and 54 can be formed to extend through the partition plate 50 in the vertical direction.

[0390] Air flowing into the upper electrical chamber 10c through the cold air inlet 5 can flow into the lower electrical chamber 10b through the through holes 52 and 54. This air flowing into the electrical chambers 10b, 10c, and 10d can cool the electrical components located in the lower electrical chamber 10b.

[0391] Additionally, a portion of the air flowing into the lower electrical chamber 10b can flow into the cooking chamber 10a (see reference). ​ For this purpose, a side opening 11a may be provided in the cavity 11. The side opening 11a may form a passage connecting at least one of the lower electrical chamber 10b and the upper electrical chamber 10c to the cooking chamber 10a.

[0392] In this embodiment, a side hole 11a is shown disposed in the lower electrical chamber 10b. As an example, the side hole 11a can be formed in the cavity 11 to extend through in the lateral direction, forming a passage connecting the lower electrical chamber 10b and the cooking chamber 10a within the cavity 11. This side hole 11a can be disposed on the front side of the support member 40.

[0393] The cooking device in this embodiment may further include a blocking plate 55. The blocking plate 55 may divide the upper electrical chamber 10c along the front and back, such that the front area of ​​the upper electrical chamber 10c is divided into an intake chamber 10d.

[0394] As an example, the blocking plate 55 can form a longitudinal wall surface orthogonal to the front-rear axis. This blocking plate 55 can be disposed on the upper side of the partition plate 50 and combined with the top surface of the partition plate 50.

[0395] With the blocking plate 55 arranged in this way, the area between the front plate 12 and the blocking plate 55 in the upper electrical chamber 10c can be divided into the intake chamber 10d.

[0396] The partition plate 50 may be provided with a plurality of through holes 52, 54. As an example, the partition plate 50 may be provided with a first through hole 52 and a second through hole 54. The first through hole 52 and the second through hole 54 may be configured to be separated in the front-back direction by a blocking plate 55.

[0397] The first through hole 52 can form a passage connecting the intake chamber 10d and the lower electrical chamber 10b. This first through hole 52 can be disposed on the front side of the blocking plate 55 and the cooling fan 6, and is formed in the partition plate 50 to extend through in the vertical direction.

[0398] The second through hole 54 can form a passage connecting the upper electrical chamber 10c and the lower electrical chamber 10b on the rear side of the intake chamber 10d. This second through hole 54 can be disposed on the rear side of the blocking plate 55 and the cooling fan 6, and is formed in the partition plate 50 to extend through in the vertical direction.

[0399] According to this embodiment, an upper support portion 43 may be disposed on the rear side of the partition plate 50. The upper support portion 43 may be disposed on the corner spaces 10g and 10h, and divide the corner spaces 10g and 10h vertically. Through the upper support portion 43, the corner spaces 10g and 10h may be divided into an upper corner space 10g and a lower corner space 10h.

[0400] The lower corner space 10h can be disposed on the lower side of the upper support 43. The upper boundary surface of the lower corner space 10h can be defined by the upper support 43, the front boundary surface of the lower corner space 10h can be defined by the front support 42, and the right boundary surface of the lower corner space 10h can be defined by the side support 41. The corner fan assembly 200 can be disposed in the lower corner space 10h.

[0401] The upper corner space 10g can be disposed on the upper side of the upper support 43. The upper corner space 10g can be disposed on the rear side of the upper electrical room 10c and communicate with the upper electrical room 10c on the rear side of the upper electrical room 10c.

[0402] At least one of the electrical components arranged in the upper electrical compartment 10c may be disposed in the upper support portion 43. As an example, a noise filter connected to the corner fan assembly 200 may be disposed in the upper corner space portion 10g, and the noise filter may be disposed on the top surface of the upper support portion 43.

[0403] Air flowing into the lower electrical chamber 10b via the cooling fan 6 can flow into the upper electrical chamber 10c through the second through hole 54. This air flowing into the upper electrical chamber 10c can cool the electrical components mounted on the upper support 43 as it passes through the upper corner space 10g.

[0404] On the other hand, the upper electrical chamber 10c and the lower electrical chamber 10b can be connected by a connecting flow path 39. The connecting flow path 39 can form a passage for air flowing into the lower electrical chamber 10b via the cooling fan 6 to flow into the air supply sections 100 and 200 via the upper electrical chamber 10c. For example, the connecting flow path 39 can form a passage for air flowing into the electrical chambers 10b, 10c, and 10d to flow into the corner fan assembly 200 via the upper corner space 10g.

[0405] Additionally, a through hole 41b may be provided in the side support portion 41. The through hole 41b is configured to allow the space surrounded by the side support portion 41 and the front support portion 42 to be opened to the side, namely the lower corner space portion 10h.

[0406] The connecting flow path 39 can form a passage connecting the through hole 41b and the upper electrical chamber 10c, and more specifically, it can form a passage connecting the through hole 41b and the upper corner space 10g. This connecting flow path 39 can communicate with the upper corner space 10g and the lower corner space 10h respectively on their sides. The connecting flow path 39 and the lower corner space 10h can be connected via the through hole 41b.

[0407] As described above, the connecting flow path portion 39 can be formed by connecting flow path forming members 37 and 38. The first partition portion 37 in the connecting flow path forming members 37 and 38 can be formed as a longitudinal wall configured to be spaced apart from the side of the side support portion 41 by a predetermined interval. The second partition portion 38 can be formed as a wall on the lower side of the through hole 41b, connecting and linking the side support portion 41 and the first partition portion 37.

[0408] The two sides of the connecting flow path 39 can be defined by the side support 41 and the first partition 37. For example, the left side of the connecting flow path 39 can be defined by the side support 41, and the right side of the connecting flow path 39 can be defined by the first partition 37. The bottom surface of the connecting flow path 39 can be defined by the second partition 38.

[0409] Air flowing into the upper electrical chamber 10c can flow into the connecting flow path 39 through the upper corner space 10g. Air flowing into the connecting flow path 39 can flow into the lower corner space 10h through the through hole 41b, and then be drawn into the corner fan assembly 200.

[0410] In the lower corner space 10h, the suction force of the corner fan assembly 200 can function. This suction force acting on the lower corner space 10h may also affect the connecting flow path 39 and the upper corner space 10g connected to the lower corner space 10h. That is, the suction force of the corner fan assembly 200 can affect the upper corner space 10g, and this suction force can function as a force that causes the air flowing into the upper corner space 10g to flow towards the lower corner space 10h.

[0411] Ultimately, the suction of the corner fan assembly 200 can act as a force to guide the flow of air from the lower electrical chamber 10b into the upper electrical chamber 10c through the connecting flow path 39 to the lower corner space 10h.

[0412] The following describes the airflow in electrical rooms 10b, 10c, and 10d.

[0413] like ​ As shown, outside air can flow into the interior of the main body 10 through the cold air inlet 5. Thus, the air passing through the cold air inlet 5 can...​ As shown, it flows into the intake chamber for 10 days.

[0414] Air flowing into the intake chamber 10d can flow down to the lower electrical chamber 10b via the first through-hole 52 and the partition plate 50. In the lower electrical chamber 10b, air can flow rearwards by the action of the cooling fan 6. This rearward airflow from the lower electrical chamber 10b can cool the electrical components disposed in the lower electrical chamber 10b.

[0415] A portion of the air flowing in the lower electrical chamber 10b can flow into the electrical chamber through the intake port 1 via the cavity 11. Another portion of the air flowing in the lower electrical chamber 10b can flow into the upper electrical chamber 10c through the second through hole 54 via the partition plate 50.

[0416] In the upper electrical chamber 10c, air can be drawn towards the connecting flow path 39 by the suction of the corner fan assembly 200. For example, the air flowing into the upper electrical chamber 10c can cool electrical components as it passes through the upper corner space 10g, and then... ​ As shown, it flows into the connecting flow path section 39.

[0417] Air flowing to the connecting flow path 39 can flow through the through hole 41b and the side support 41 into the lower corner space 10h, and then be drawn into the corner fan assembly 200. That is, as ​ As shown, the air flowing into the lower corner space 10h from the connecting flow path 39 can merge with the air flowing into the body 10 through the air intake 1 and be drawn into the corner fan assembly 200, and then discharged into the exhaust flow path A.

[0418] like ​ As shown, the flow paths formed in the electrical chambers 10b, 10c, 10d, corner spaces 10g, 10h, and connecting flow path 39 allow the suction force provided by the corner fan assembly 200 and the cooling fan 6 to be added together in the electrical chambers 10b, 10c, and 10d. Therefore, the airflow inside the electrical chambers 10b, 10c, and 10d can be formed more smoothly, which helps to cool the electrical components arranged in the electrical chambers 10b, 10c, and 10d more effectively.

[0419] In addition, the flow paths formed in the electrical chambers 10b, 10c, 10d, corner spaces 10g, 10h and connecting flow path 39 as described above can cause the air flowing into the electrical chambers 10b, 10c, 10d to flow toward the corner fan assembly 200, thereby increasing the air intake of the corner fan assembly 200 and ultimately helping to effectively increase the air output of the corner fan assembly 200.

[0420] On the other hand, refer to​ The cooking apparatus of this embodiment may further include a flow path partition 16. The flow path partition 16 is configured to divide the space above the cavity 11 and the partition 50. This flow path partition 16 can divide the space above the cavity 11 and the partition 50 into an upper electrical chamber 10c and an upper space section 10i.

[0421] As an example, the flow path partition 16 can be formed as a longitudinal wall orthogonal to the lateral axis. This flow path partition 16 can separate the two spaces by blocking the upper electrical chamber 10c and the upper space portion 10i. For example, the flow path partition 16 can define the right boundary surface of the upper electrical chamber 10c and the left boundary surface of the upper space portion 10i.

[0422] Furthermore, the cooking apparatus of this embodiment may include a waveguide 17. The waveguide 17 is configured to transmit microwaves generated by magnetrons disposed in electrical chambers 10b, 10c, and 10d to cooking chamber 10a.

[0423] Waveguide 17 can be configured in the upper electrical chamber 10c and the upper space section 10i, and is disposed on the top surface of the partition plate 50 and the cavity 11. That is, a part of waveguide 17 can be disposed on the top surface of the partition plate 50, and the remaining part of waveguide 17 can penetrate the flow path partition plate 16 in the lateral direction and be disposed on the top surface of the cavity 11.

[0424] A space can be formed inside the waveguide 17. The inlet of the waveguide 17 connected to this space can be connected to a magnetron, and the outlet of the waveguide 17 connected to this space can be connected to the cooking chamber 10a. Microwaves flowing into the interior of the waveguide 17 through the inlet can flow into the cooking chamber 10a through the outlet of the waveguide 17.

[0425] The outlet of the waveguide 17 can be connected to the cooking chamber 10a on the top surface of the cavity 11. Thus, microwaves transmitted from the magnetron via the waveguide 17 can flow into the cooking chamber 10a from the upper side through the top surface of the cavity 11. As an example, the outlet of the waveguide 17 can be located on the upper side of the cavity 11, and approximately at the lateral center of the cavity 11.

[0426] If the vertical length of the cooking equipment is shortened, the vertical length of the cooking chamber 10a is also likely to be shortened. Even if the air supply units 100 and 200 are placed in the rear space 10f instead of the upper space 10i, thereby shortening the vertical length of the upper space 10i, the reduction in the length of the upper space 10i can only be less than the reduction in the overall length of the cooking equipment. Therefore, it is difficult to avoid the reduction in the length of the cooking chamber 10a caused by the reduction in the length of the cooking equipment.

[0427] In this case, the cooking chamber 10a has a laterally flat shape compared to the cooking chamber of a typical cooking device. In a cooking device with a cooking chamber 10a of this shape, if microwaves flow into the cooking chamber 10a through the side of the cavity 11, it is difficult to supply microwaves evenly to the entire cooking chamber 10a.

[0428] Therefore, in this embodiment, the waveguide 17 can be disposed on the top surface of the cavity 11, and microwaves can flow into the cooking chamber 10a through the top surface of the cavity 11. That is, in the cooking device of this embodiment, the supply of microwaves can be achieved through the upper side of the cooking chamber 10a, thereby enabling the uniform supply of microwaves to the entire cooking chamber 10a.

[0429] [Structure of the upper spatial section]

[0430] ​ This is a rear perspective view showing the air intake and exhaust states of the cooking device according to the first embodiment of the present invention. ​ It means ​ A three-dimensional view of the rear of the cooking equipment showing the airflow pattern inside. Additionally, ​ It is shown in magnification ​ A top view of the area surrounding the common exhaust port. ​ It is an enlarged view showing the exhaust pipe and its surroundings. ​ It is a side sectional view showing the side shape of the exhaust pipe.

[0431] Reference ​ and ​ An air recirculation outlet 11b may be provided inside the main body 10. The air recirculation outlet 11b may form a passage connecting the cooking chamber 10a and the upper space 10i on the top surface of the cavity 11. As an example, the air recirculation outlet 11b may be formed to extend through the top surface of the cavity 11 in the vertical direction.

[0432] According to this embodiment, a plurality of second exhaust ports 3 may be disposed on the upper part of the main body 10. At least one of the plurality of second exhaust ports 3 may be provided as a common exhaust port 3a. The common exhaust port 3a is configured to discharge together the air flowing from the air supply section 100, 200 to the upper space section 10i and the air flowing to the upper space section 10i through the circulating air outlet 11b.

[0433] As an example, the recirculated air outlet 11b can be positioned slightly to the right of the center in the lateral direction of the cavity 11. For instance, the recirculated air outlet 11b can be positioned to overlap with at least a portion of the common exhaust port 3a in the longitudinal direction.

[0434] According to this embodiment, a plurality of second exhaust ports 3 and cold air inlets 5 can be arranged in a lateral direction. As an example, at least one of the plurality of second exhaust ports 3 located at the position furthest from the cold air inlet 5 can be provided as a common exhaust port 3a. For example, the cold air inlet 5 can be located to the left of the second exhaust ports 3, and one of the plurality of second exhaust ports 3 located on the far right can be provided as a common exhaust port 3a.

[0435] As another example, at least one of the plurality of second exhaust ports 3 arranged in the lateral direction, located at the position furthest from the electrical rooms 10b, 10c, 10d, can also be provided as a common exhaust port 3a.

[0436] As another example, at least one of the plurality of second exhaust ports 3 arranged in the lateral direction, positioned closest to the expansion plate 18, can also be provided as a common exhaust port 3a. In this case, at least a portion of the common exhaust port 3a can be configured to overlap with the expansion plate 18 in the vertical direction.

[0437] Additionally, an exhaust duct 70 may be provided in the upper space section 10i. The exhaust duct 70 is configured to direct the flow of air discharged from the cooking chamber 10a to the recirculated air outlet 11b toward the common exhaust outlet 3a.

[0438] In this embodiment, the recirculated air outlet 11b can be configured at a position slightly off-center from the rear side of the cavity 11 in the front-rear direction. For example, the recirculated air outlet 11b can be configured on the top surface of the cavity 11 and at a position adjacent to the rear right corner of the cavity 11.

[0439] The exhaust duct 70 can direct the flow of air discharged from the recirculated air outlet 11b located in this position to the common exhaust port 3a located adjacent to the front of the main body 10.

[0440] Additionally, the cooking apparatus of this embodiment may include an expansion plate 18. The expansion plate 18 can divide the side space portion 10e into an expanded upper space portion 10j, with a portion of the side space portion 10e being separated into an expanded upper space portion 10j. Through the expansion plate 18, the upper region of the expansion plate 18 in the side space portion 10e can be divided into the expanded upper space portion 10j.

[0441] [Expansion plate]

[0442] Reference ​ , ​ as well as ​At least a portion of the expansion plate 18 may be disposed in the side space portion 10e. In this embodiment, the expansion plate 18 is exemplified as being disposed in a side space portion 10e that is not an electrical chamber 10b, 10c, 10d among a pair of side spaces 10e disposed inside the cooking appliance.

[0443] As an example, the expansion plate 18 can be formed into a transverse plane orthogonal to the vertical axis. For instance, the expansion plate 18 can be formed into a plane parallel to the top surface of the cavity 11.

[0444] Preferably, the top surface of the expansion plate 18 and the top surface of the cavity 11 can form a coplanar plane. The top surface of the cavity 11 can define the bottom surface of the upper space portion 10i, and the top surface of the expansion plate 18 can define the bottom surface of the expanded upper space portion 10j. Thus, the bottom surfaces of the upper space portion 10i and the bottom surfaces of the expanded upper space portion 10j can be arranged on the same plane.

[0445] The expanded upper space portion 10j, configured in this way, can communicate with the upper space portion 10i on the upper side of the side space portion 10e. That is, the expanded upper space portion 10j can be disposed on the upper side of the side space portion 10e and the side of the upper space portion 10i, and connected to the upper space portion 10i in the lateral direction.

[0446] According to this embodiment, on the upper side of the cavity 11, the upper space portion 10i and the expanded upper space portion 10j are connected to form a single space portion, thereby forming exhaust spaces 10i and 10j on the upper side of the cavity 11 and the side space portion 10e. In this embodiment, the exhaust spaces 10i and 10j can be defined as a single space by connecting the upper space portion 10i and the expanded upper space portion 10j on the upper side of the cavity 11 and the expansion plate 18, which are connected as a single space.

[0447] The exhaust spaces 10i and 10j formed on the upper side of the cavity 11 and the expansion plate 18 can communicate with the exhaust ports 2, 3 and 4 disposed on the top surface of the main body 10. The exhaust ports 2, 3 and 4 can open the space connecting the upper space 10i and the expanded upper space 10j, that is, the exhaust spaces 10i and 10j, to the outside of the main body 10.

[0448] The side space section 10e and the rear space section 10f can communicate with the lower space section. The side space section 10e and the rear space section 10f can be connected to the lower space section vertically or laterally. The air intake 1 can communicate with the lower space section, and the side space section 10e and the rear space section 10f can communicate with the air intake 1 via the lower space section.

[0449] A portion of the expansion plate 18 may be disposed in the rear space portion 10f. Therefore, a portion 18a of the expansion plate 18 (hereinafter referred to as "side partition of the expansion plate") may be disposed in the side space portion 10e, and another portion 18b of the expansion plate 18 (hereinafter referred to as "rear partition of the expansion plate") may be disposed in the rear space portion 10f.

[0450] As described above, the side partition 18a of the expansion plate 18 can divide the side space 10e into an expanded upper space 10j, with a portion of the side space 10e being divided into an expanded upper space 10j. Furthermore, the rear partition 18b of the expansion plate 18 can divide a portion of the rear space 10f into an expanded upper space 10j, with a portion of the rear space 10f being divided into an expanded upper space 10j.

[0451] That is, the expansion plate 18 can divide a part of the rear space 10f and the side space 10e into an expanded upper space 10j.

[0452] A first connecting portion 18c may be provided on the expansion plate 18. The first connecting portion 18c may be provided for the connection between the expansion plate 18 and the cavity 11. As an example, the first connecting portion 18c may be formed to protrude laterally from at least one of the side partition portion 18a and the rear partition portion 18b. This first connecting portion 18c may face the top surface of the cavity 11 in the vertical direction and be connected to the cavity 11.

[0453] The connection between the first joint 18c and the cavity 11 can be achieved by a joining method based on welding or the like, or by a fastening method based on screws or the like.

[0454] In this embodiment, the first connecting portion 18c is shown to protrude laterally from the side partition portion 18a. As another example, the first connecting portion 18c may also be formed to protrude forward from the rear partition portion 18b. As yet another example, the first connecting portion 18c may also protrude longitudinally from at least one of the side partition portion 18a and the rear partition portion 18b and connect with the side of the cavity 11.

[0455] Additionally, the expansion plate 18 may include at least one of a second joint 18d and a third joint 18e. The second joint 18d and the third joint 18e may be provided for the connection between the expansion plate 18 and the housing 13.

[0456] The second joint 18d can be provided in a form that protrudes from either the side partition 18a or the first joint 18c. In this embodiment, the first joint 18c protrudes laterally from the side partition 18a, and the second joint 18d protrudes longitudinally from the first joint 18c.

[0457] As an example, the second joint 18d can form a longitudinal wall orthogonal to the lateral axis. A plane parallel to the top surface of the housing 13 can be formed at the upper end of this second joint 18d.

[0458] The third joint 18e can be provided in a form that protrudes from the rear partition 18b. As an example, the third joint 18e can form a longitudinal wall orthogonal to the front-rear axis. A plane parallel to the top surface of the housing 13 can be formed at the upper end of such a third joint 18e.

[0459] The vertical lengths of the second joint 18d and the third joint can be set according to the distance between the expansion plate 18 and the housing 13, respectively. The second joint 18d and the third joint 18e thus formed can be joined to the housing 13 on the lower side.

[0460] Through the connection between the second joint 18d and the housing 13, and the connection between the third joint 18e and the housing 13, the expansion plate 18 can support the housing 13 so that the top surface of the housing 13 does not sag downwards. In addition, the expansion plate 18 can be connected to a plurality of structures at a plurality of positions using the first joint 18c, the second joint 18d, and the third joint 18e, thereby being stably fixed inside the cooking device.

[0461] As an example, the second joint 18d can be disposed between the upper space 10i and the expanded upper space 10j. That is, the second joint 18d can be disposed in the exhaust spaces 10i and 10j in a longitudinal wall form that blocks a portion of the space between the upper space 10i and the expanded upper space 10j in the lateral direction.

[0462] A plurality of vent holes may be provided in this second joint 18d. Each vent hole may be formed to extend through the second joint 18d in the lateral direction, and vent holes may be provided in most areas of the second joint 18d.

[0463] This second joint 18d, which has a plurality of vent holes, not only provides a structure for the connection between the expansion plate 18 and the housing 13, but also minimizes the obstruction of airflow in the exhaust spaces 10i, 10j by the second joint 18d.

[0464] In this embodiment, a third joint 18e is illustrated in the region where the rear space portion 10f and the upper space portion 10i overlap or is very close to that region. This third joint 18e can be positioned adjacent to the rear fan assembly 100 disposed in the rear space portion 10f.

[0465] The third joint 18e, configured in this way, can incorporate electrical components related to the rear fan assembly 100, such as capacitors connected to the rear fan assembly 100. That is, the third joint 18e can function as a structure providing the connection between the expansion plate 18 and the housing 13, and as a structure for housing the electrical components related to the rear fan assembly 100.

[0466] [Exhaust morphology based on exhaust space]

[0467] Reference ​ , ​ An upper space portion 10i may be formed on the upper side of the cavity 11. In addition, an expanded upper space portion 10j may be formed on the upper side of the side space portion 10e that is not an electrical room 10b, 10c, or 10d.

[0468] As described above, the upper space portion 10i and the expanded upper space portion 10j can be connected to form a space portion on the upper side of the cavity 11, so exhaust spaces 10i and 10j can be formed on the upper side of the cavity 11 and the side space portion 10e.

[0469] The expanded upper space 10j can be formed using an expansion plate 18 that divides the side space 10e vertically. In this embodiment, the expansion plate 18 makes the exhaust spaces 10i and 10j include not only the upper space 10i but also the expanded upper space 10j, thereby enabling the exhaust spaces 10i and 10j to expand in the lateral direction. Furthermore, the expansion plate 18 also serves to separate the side space 10e from the exhaust spaces 10i and 10j.

[0470] As the exhaust spaces 10i and 10j are expanded to include an upper space 10i and an expanded upper space 10j, the size of the flow path required to allow air to flow from the second exhaust port 3 through the exhaust spaces 10i and 10j can be expanded. In particular, the size of the exhaust spaces 10i and 10j can be further expanded in the lateral direction equivalent to the size of the expanded upper space 10j.

[0471] That is, in this embodiment, the expansion plate 18 divides the side space 10e into an expanded upper space 10j that can be connected to the upper space 10i, thereby providing the effect of expanding the size of the exhaust spaces 10i and 10j.

[0472] As described above, in the cooking apparatus of this embodiment, the air supply units 100 and 200 are disposed in the rear space 10f, which is not the upper space 10i. Therefore, it is not necessary to ensure the space required for installing the air supply units 100 and 200 in the upper space 10i, and thus the height of the upper space 10i can be reduced compared to the case where the air supply units are disposed in the upper space.

[0473] In the cooking apparatus of this embodiment, one method for minimizing the volume of the cooking chamber while reducing the overall size of the cooking apparatus, namely, one method for minimizing the height of the cooking chamber while reducing the overall height of the cooking apparatus, is to reduce the height of the upper space portion 10i.

[0474] Therefore, in the cooking apparatus of this embodiment, the height of the upper space portion 10i is set to be lower than the height of the upper space portion of existing cooking apparatuses. That is, in the cooking apparatus of this embodiment, the height of the upper space portion 10i is set to be much smaller than the height of the rear fan assembly 100 or the corner fan assembly 200.

[0475] As described above, if the height of the upper space 10i decreases, the volume of the upper space 10i can only decrease as well. The upper space 10i is a space related to exhaust, therefore, if the volume of the upper space 10i decreases, the size of the flow path required for the air discharged from the second exhaust port 3 can only decrease accordingly.

[0476] If the size of the flow path required for the air discharged from the second exhaust port 3 decreases, the exhaust performance of the cooking equipment can only decrease. Furthermore, if the exhaust performance of the cooking equipment decreases, the intake performance of the cooking equipment can only decrease as well, ultimately resulting in a decline in the cooking gas removal performance of the cooking equipment.

[0477] In this embodiment, the expansion plate 18, which divides the side space 10e vertically, separates the expanded upper space 10j from the side space 10e and connects the expanded upper space 10j to the upper space 10i. This allows the overall size of the exhaust spaces 10i and 10j, including the upper space 10i, to expand. Therefore, the size of the flow path required for the air discharged from the second exhaust port 3 through the exhaust spaces 10i and 10j can be effectively expanded.

[0478] As described above, if the size of the flow path required for the air to flow from the second exhaust port 3 through the exhaust spaces 10i and 10j is expanded, the exhaust performance of the cooking equipment can be improved accordingly, and ultimately, the cooking gas removal performance of the cooking equipment can be improved.

[0479] On the other hand, structures such as exhaust pipes 70 and lamp covers 80 are arranged in the exhaust spaces 10i and 10j. These structures have a shape that protrudes from the top of the cavity 11 into the interior of the exhaust spaces 10i and 10j to perform their respective functions.

[0480] For example, the exhaust duct 70 is formed in a shape that protrudes from the top surface of the cavity 11 to create an internal flow path for the air exhausted from the cooking chamber. Furthermore, the lamp cover 80 is formed in a shape that protrudes from the top surface of the cavity 11 to cover the lamp on the upper side and is integrated with the front panel 12.

[0481] Both the exhaust duct 70 and the lamp cover 80 can be formed in a shape that includes an inclined surface. That is, although the exhaust duct 70 and the lamp cover 80 are inevitably formed in a shape that protrudes from the top surface of the cavity 11 in order to perform their respective functions, they can be formed in a shape that can reduce the flow resistance caused by the exhaust duct 70 and the lamp cover 80 in the exhaust spaces 10i and 10j.

[0482] That is, in this embodiment, the size of the exhaust spaces 10i and 10j is expanded by expanding the upper space portion 10j, thereby expanding the size of the flow path required for the air discharged from the second exhaust port 3 through the exhaust spaces 10i and 10j. Furthermore, the exhaust pipe 70 and lamp cover 80 arranged in the exhaust spaces 10i and 10j are shaped to reduce the flow resistance caused by the exhaust pipe 70 and lamp cover 80. Therefore, the air discharged from the second exhaust port 3 through the exhaust spaces 10i and 10j can be formed smoothly.

[0483] Therefore, compared with existing cooking devices with similar cooking capacity, the cooking device of this embodiment is not only smaller in overall size but also provides equivalent or better cooking gas removal performance.

[0484] Furthermore, the expansion plate 18 can function as a blocking wall to seal the side space 10e and the exhaust spaces 10i and 10j. Therefore, the side space 10e can be separated from the exhaust spaces 10i and 10j by the expansion plate 18.

[0485] That is, through the expansion plate 18, a space is formed on the upper side of the expansion plate 18 connecting the upper space 10i and the expanded upper space 10j, but the passage between the side space 10e and the exhaust spaces 10i and 10j is blocked by the expansion plate 18.

[0486] According to this embodiment, the side space portion 10e is connected to the lower space portion formed between the intake port 1 and the cavity 11. Therefore, the side space portion 10e can be referred to as the space connected to the intake port 1. Furthermore, the exhaust spaces 10i and 10j can be referred to as the spaces connected to the second exhaust port 3. That is, the side space portion 10e can be referred to as the space related to intake, and the exhaust spaces 10i and 10j can be referred to as the space related to exhaust.

[0487] The expansion plate 18 can separate the exhaust spaces 10i and 10j from the side space 10e, thus separating the exhaust-related space from the intake-related space. As a result, the exhaust-related space can be expanded by expanding the upper space 10j, and the intake-related space can be expanded to the size of the space occupied by the side space 10e.

[0488] That is, as the exhaust spaces 10i, 10j and the side space 10e are separated by the expansion plate 18, the space related to exhaust and the space related to intake can be ensured to be of sufficient size for intake or exhaust respectively.

[0489] In addition, since the exhaust spaces 10i, 10j and the side space 10e are separated by the expansion plate 18, the phenomenon of air from the exhaust spaces 10i, 10j being re-inhaled into the air supply sections 100, 200 can be effectively suppressed, that is, the occurrence of backflow can be effectively suppressed, thus effectively improving the exhaust performance of the cooking equipment.

[0490] On the other hand, in the cooking device of this embodiment, a plurality of second exhaust ports 3 may be provided. Each second exhaust port 3 may be provided on the top surface of the main body 10 and in a position adjacent to the front of the main body 10 and communicating with the exhaust spaces 10i and 10j.

[0491] On the main body 10, the cold air inlet 5 and a plurality of second exhaust ports 3 can be arranged in the lateral direction. In addition, any one of the plurality of second exhaust ports 3 can be provided as a common exhaust port 3a.

[0492] In this embodiment, a case is illustrated where the cold air inlet 5 is located on the left side of the second exhaust port 3, and any one of the rightmost second exhaust ports 3 among the plurality of second exhaust ports 3 is provided as a common exhaust port 3a.

[0493] At least a portion of the common exhaust port 3a can be configured to overlap with at least a portion of the pipe outlet 70c provided in the exhaust duct 70. That is, when viewed from above, at least a portion of the pipe outlet 70c can be exposed upward through the common exhaust port 3a. Therefore, air exhausted through the pipe outlet 70c can be effectively discharged through the common exhaust port 3a.

[0494] A portion of the air flowing into the electrical chambers 10b, 10c, and 10d through the cold air inlet 5 can flow into the cooking chamber 10a. The air flowing into the cooking chamber 10a can be discharged into the exhaust pipe 70 along with the steam, gases, etc. generated in the cooking chamber 10a during the cooking process of the cooking equipment.

[0495] Air flowing into the exhaust duct 70 can be discharged through the duct outlet 70c, and air discharged from the exhaust duct 70 can be discharged to the outside of the cooking equipment through the common exhaust port 3a. That is, the common exhaust port 3a can be used as an outlet for air discharged from the cooking chamber to the outside of the cooking equipment.

[0496] In this embodiment, at least a portion of the common exhaust port 3a is arranged on the left side of the expanded upper space portion 10j. This common exhaust port 3a can be arranged above the boundary between the upper space portion 10i and the expanded upper space portion 10j. That is, when viewed from above, the boundary between the upper space portion 10i and the expanded upper space portion 10j can be exposed to the upper side of the cooking device through the common exhaust port 3a.

[0497] As an example, approximately the left half of the common exhaust port 3a can be positioned on the upper side of the upper space portion 10i. Furthermore, the remaining half of the common exhaust port 3a can be positioned on the upper side of the expanded upper space portion 10j.

[0498] This shared exhaust port 3a allows air discharged from the exhaust pipe 70 and air flowing into the exhaust spaces 10i and 10j from the air supply sections 100 and 200 to be discharged together. That is, steam and gas discharged from the cooking chamber and cooking gases drawn in through the air supply sections 100 and 200 can be discharged together through the shared exhaust port 3a.

[0499] According to this embodiment, the exhaust spaces 10i and 10j include an upper space 10i and an expanded upper space 10j. Air drawn in through the air supply sections 100 and 200 can flow not only to the upper space 10i but also to the expanded upper space 10j. In particular, the air flowing from the air supply sections 100 and 200 to the expanded upper space 10j can be discharged to the outside of the cooking equipment through a common exhaust port 3a.

[0500] Of course, the air flowing from the air supply section 100, 200 to the expanded upper space section 10j does not necessarily have to be discharged to the outside of the cooking equipment only through the common exhaust port 3a, but can also be discharged to the outside of the cooking equipment through other second exhaust ports 3 that are not the common exhaust port 3a.

[0501] If there is no expansion plate 18 inside the main body 10, and thus no expansion upper space 10j is formed inside the main body 10, then the area occupied by the exhaust spaces 10i and 10j can only be reduced to only the upper space 10i.

[0502] In this case, the lower area of ​​the common exhaust port 3a is mostly occupied by the exhaust pipe 70, making it difficult to form a passage connecting the common exhaust port 3a and the exhaust spaces 10i and 10j.

[0503] Furthermore, if there is no expansion plate 18 inside the main body 10, the common exhaust port 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 periphery of the common exhaust port 3a.

[0504] As a result, it becomes very difficult to exhaust the air flowing from the air supply sections 100 and 200 to the exhaust spaces 10i and 10j through the common exhaust port 3a to the outside of the cooking equipment. Consequently, the common exhaust port 3a mainly exhausts only the steam and gas exhausted from the cooking chamber, and it is almost impossible to exhaust the cooking gas drawn in by the air supply sections 100 and 200.

[0505] In contrast, in the cooking device of this embodiment, the side space 10e and the upper expanded upper space 10j are separated by the expansion plate 18, and the area occupied by the exhaust spaces 10i and 10j extends beyond the upper space 10i to the upper expanded upper space 10j, which is located below the common exhaust port 3a.

[0506] Therefore, the cooking device of this embodiment can discharge the steam and gas discharged from the cooking chamber and the cooking gas drawn in by the air supply units 100 and 200 together through the common exhaust port 3a.

[0507] [An example of the third state of cooking equipment]

[0508] ​ This is a rear view showing the position of the rear fan assembly compared to the position of the third exhaust port.

[0509] Reference ​ and ​ The third exhaust port 4 can be disposed on the back of the cooking device and formed in the rear panel 15 to extend through in the front-to-back direction. This third exhaust port 4 can be disposed on the rear side and the upper side of the rear fan assembly 100. In addition, the third exhaust port 4 can be disposed on the rear side of the rear space portion 10f and the upper space portion 10i.

[0510] At least a portion of the third exhaust port 4 can be disposed at the lateral center C1 of the main body 10. As an example, the lateral center C3 of the third exhaust port 4 can be disposed at the lateral center of the rear plate 15, thereby the third exhaust port 4 can be disposed at the lateral center C1 of the main body 10.

[0511] A rear fan assembly 100 is disposed in front of the third exhaust port 4. According to this embodiment, the rear fan assembly 100 may be configured such that a pair of fan modules are connected to both sides of the fan motor. That is, the rear fan assembly 100 may include a pair of impellers 120 arranged in the lateral direction, and a fan motor may be disposed at the lateral center C2 of the rear fan assembly 100.

[0512] The rear fan assembly 100 configured in this way can draw in air using a pair of first intake ports 112 located on both sides of the rear fan assembly 100 in the lateral direction, and expel air using a pair of first exhaust ports 114 located on the upper side of the rear fan assembly 100.

[0513] In the rear space 10f, the rear fan assembly 100 and the corner fan assembly 200 can be arranged in the lateral direction. The corner fan assembly 200 can be disposed on the right side of the rear fan assembly 100 in the lateral direction, and the rear fan assembly 100 can be configured to be separated from the corner fan assembly 200 by a predetermined interval in the lateral direction.

[0514] According to this embodiment, the rear fan assembly 100 can be configured at a position offset from the side center C1 of the main body 10 to the left. As an example, the side center C2 of the rear fan assembly 100 can be located at a position offset to the left from the side center C1 of the main body 10.

[0515] For example, the fan motor of the rear fan assembly 100 can be configured to be positioned to the left of the center C1 from the side of the main body 10, and the distance between the left end of the rear fan assembly 100 and the left end of the main body 10 can be set to be shorter than the distance between the right end of the rear fan assembly 100 and the right end of the main body 10.

[0516] In this case, the lateral center C2 of the rear fan assembly 100 can be positioned offset from the lateral center C3 of the third exhaust port 4 located at the lateral center C1 of the main body 10, moving away from the corner fan assembly 200. That is, the rear fan assembly 100 can be positioned to the left relative to the third exhaust port 4.

[0517] Furthermore, in this case, the lateral center C3 of the third exhaust port 4 can be positioned between the lateral center C2 of the rear fan assembly 100 and the corner fan assembly 200 in this configuration. That is, the third exhaust port 4 can be positioned at the lateral center C1 of the main body 10, but offset to the right relative to the rear fan assembly 100.

[0518] As an example, at least a portion of the rear fan assembly 100 and the corner fan assembly 200 may be configured on the outer side of the third exhaust port 4 in a lateral direction. For example, the corner fan assembly 200 may be configured on the outer side of the third exhaust port 4 in a lateral direction, and may also be configured on one side of the third exhaust port 4 in a lateral direction, i.e., the right side. At least a portion of the rear fan assembly 100 may be configured on the outer side of the third exhaust port 4 in a lateral direction, and may also be configured on the other side of the third exhaust port 4 in a lateral direction, i.e., the left side.

[0519] As an example, the first exhaust port 114 on the right side of the pair of first exhaust ports 114 provided in the rear fan assembly 100 can be configured in the lateral inner region of the third exhaust port 4. In addition, at least a portion of the first exhaust port 114 on the left side of the pair of first exhaust ports 114 provided in the rear fan assembly 100 can be configured in the region that is distancing itself from the third exhaust port 4 to the left.

[0520] Typically, the third exhaust port 4 and the first exhaust port 2 are positioned laterally at the center of the cooking appliance. The third exhaust port 4 can be connected to a pipe or conduit embedded in the wall where the cooking appliance is installed, and the first exhaust port 2 can be connected to a pipe or conduit embedded in the wall or ceiling where the cooking appliance is installed.

[0521] Typically, the position of the piping or conduit connected to the third exhaust port 4 is set with the lateral position of the third exhaust port 4 located at the lateral center of the cooking device. That is, the position of the piping or conduit connected to the third exhaust port 4 is typically set such that, when the cooking device is set in a set position, the third exhaust port 4, which is located at the lateral center of the cooking device, can be connected to the piping or conduit in a straight line in the front-back direction.

[0522] Therefore, if the third exhaust port 4 is not positioned at the center of the cooking device in the lateral direction, it is difficult to achieve a normal connection between the pipes or conduits embedded in the wall where the cooking device is installed and the third exhaust port 4. Considering this, in the cooking device of this embodiment, the third exhaust port 4 is positioned at the center C1 of the main body 10 in the lateral direction.

[0523] According to this embodiment, compared to the third exhaust port 4 which is configured at the side center C1 of the main body 10, the rear fan assembly 100 can be configured at a position slightly to the left of the side center C1 of the main body 10.

[0524] In the rear space 10f, not only is a rear fan assembly 100 provided, but also a corner fan assembly 200 is provided, and the rear fan assembly 100 and the corner fan assembly 200 are configured to be separated by a predetermined interval in the lateral direction. The rear fan assembly 100 draws in air through a first intake port 112 provided on the side of the rear fan assembly 100, and the corner fan assembly 200 discharges air through a second exhaust port 214 provided on the side of the corner fan assembly 200.

[0525] Either of the first intake ports 112 is disposed on the side facing the corner fan assembly 200, and the second exhaust port 214 is disposed on the side facing the rear fan assembly 100. That is, the first intake port 112 and the second exhaust port 214 disposed on the right side of the rear fan assembly 100 are configured to face each other in the lateral direction.

[0526] Therefore, at least a portion of the rear fan assembly 100 is disposed laterally outside the third exhaust port 4. For example, a portion of the left side of the rear fan assembly 100 may be disposed laterally outside the third exhaust port 4.

[0527] [Overall structure of the exhaust guide component]

[0528] ​ This is a rear view showing the state in which an exhaust guide component is installed inside the cooking equipment. ​ It is shown ​ A side sectional view of the internal structure of the cooking equipment. Additionally, ​ It means from ​ A three-dimensional view of the back of the cooking equipment with the cabinet and back panel removed. ​ yes ​ Rear view of the cooking equipment ​ yes ​ A top view of the cooking equipment.

[0529] Reference ​ The cooking apparatus of one embodiment of the present invention may further include an exhaust guiding member 35. The exhaust guiding member 35 is configured to guide the flow of air expelled from the air supply sections 100 and 200.

[0530] As an example, in the third state (refer to...) ​ and ​ When using a cooking device, that is, when the cooking device is used in a way that allows cooking gases drawn into the cooking device to be discharged to the outside via the third exhaust port 4, the exhaust guide member 35 may be provided on the cooking device.

[0531] For example, when the cooking equipment is used in the first or second state, that is, when the cooking equipment is used to exhaust the cooking gas drawn into the cooking equipment to the outside through the first exhaust port 2 or the second exhaust port 3, the exhaust guide member 35 is not provided in the cooking equipment, but the exhaust guide member 35 can be provided in the cooking equipment only when the cooking equipment is used in the third state.

[0532] According to this embodiment, the first exhaust port 114 is disposed on the top surface of the rear fan assembly 100. The exhaust guide member 35 may be disposed above the first exhaust port 114. Additionally, the third exhaust port 4 may be disposed above the first exhaust port 114. Furthermore, at least a portion of the exhaust guide member 35 may be disposed between the first exhaust port 114 and the third exhaust port 4.

[0533] At least a portion of the exhaust guide member 35 can be configured to block the space between the rear plate 15 and the cavity 11. As an example, the exhaust guide member 35 can be configured in the rear space 10f and to block the space between the back of the cavity 11 and the rear plate 15. This exhaust guide member 35 can form a rear guide flow path B inside the cooking device.

[0534] The rear guide flow path B is configured to guide the flow of air expelled from the air supply sections 100 and 200 toward the third exhaust port 4. As an example, the rear guide flow path B can be disposed in the rear space section 10f. This rear guide flow path B can connect the air supply sections 100 and 200 and the third exhaust port 4, and is formed in the space surrounded by the air supply sections 100 and 200, the rear plate 15, and the exhaust guide member 35.

[0535] The inlet of this rear guide flow path B can be opened toward the air supply sections 100 and 200. For example, the inlet of the rear guide flow path B can be opened toward the first outlet 114 of the rear fan assembly 100 and the second outlet 214 of the corner fan assembly 200. Furthermore, the outlet of the rear guide flow path B can be opened toward the third exhaust port 4.

[0536] Furthermore, at least a portion of the exhaust guide member 35 can be configured to block the space between the third exhaust port 4 and the upper space 10i. Additionally, at least a portion of the exhaust guide member 35 can be configured to block the space between the first discharge port 114 and the upper space 10i. That is, the exhaust guide member 35 can form a wall that blocks the passage between the third exhaust port 4 and the upper space 10i, and also blocks the passage between the first discharge port 114 and the upper space 10i.

[0537] Therefore, the rear guide flow path B can be formed in a space that is open only to the air supply sections 100, 200 and the third exhaust port 4 and blocked from the upper space section 10i. At this time, at least a portion of the exhaust guide member 35 can form the upper boundary surface of the rear guide flow path B and is configured to block the space between the rear guide flow path B and the upper space section 10i.

[0538] According to this embodiment, the exhaust guide member 35 can form a guide plate 36. The guide plate 36 can form the skeleton and most of the appearance of the exhaust guide member 35. This guide plate 36 can form a wall that blocks the space between the first exhaust port 114 and the upper space 10i. In addition, the guide plate 36 can form a wall that blocks the space between the third exhaust port 4 and the upper space 10i.

[0539] According to this embodiment, the guide plate 36 can be disposed on the upper side of the rear guide flow path B. As an example, the guide plate 36 can form an inclined wall that blocks the space between the first discharge port 114 and the upper space 10i and the space between the upper space 10i and the third exhaust port 4.

[0540] As an example, at least a portion of the guide plate 36 may be disposed between the first exhaust port 114 and the third exhaust port 4, and a portion of the guide plate 36 may be disposed on the upper side of the third exhaust port 4.

[0541] That is, in the vertical direction, the third exhaust port 4 can be disposed above the first exhaust port 114, the lower end of the guide plate 36 can be disposed between the first exhaust port 114 and the third exhaust port 4, and most of the area of ​​the guide plate 36 can be disposed between the first exhaust port 114 and the third exhaust port 4. In addition, the upper end of the guide plate 36 can be disposed above the first exhaust port 114.

[0542] Additionally, a portion of the guide plate 36 may be disposed in front of the first discharge port 114, and at least a portion of the guide plate 36 may be disposed between the first discharge port 114 and the third exhaust port 4.

[0543] That is, in the front-rear direction, the first discharge port 114 can be disposed in front of the third exhaust port 4, and the lower end of the guide plate 36 can be disposed in front of the first discharge port 114. Furthermore, the upper end of the guide plate 36 can be disposed between the first discharge port 114 and the third exhaust port 4, and most of the area of ​​the guide plate 36 can be disposed between the first discharge port 114 and the third exhaust port 4.

[0544] For example, the guide plate 36 can be formed as an inclined surface extending rearward from the lower side of the third exhaust port 4 and the front side of the first discharge port 114. Thus, the rear guide flow path B can form an inclined passage that rises from the first discharge port 114 toward the third exhaust port 4.

[0547] Reference ​ and ​ In this embodiment, the guide plate 36 may further include a lower connecting portion 35a. The lower connecting portion 35a is configured to allow the guide plate 36 to be connected to the rear fan assembly 100.

[0548] The lower connecting portion 35a can be connected to the guide plate 36 on the lower side of the guide plate 36. As an example, the lower connecting portion 35a can be formed in a shape that protrudes from the lower end of the guide plate 36. This lower connecting portion 35a can be attached to the top surface of the rear fan assembly 100, thereby connecting the guide plate 36 to the rear fan assembly 100. In this embodiment, the lower connecting portion 35a is shown attached to the rear fan assembly 100 on the upper and front sides of the first discharge port 114.

[0549] According to this embodiment, a fastening plate 33 may be provided on the top surface of the rear fan assembly 100. The fastening plate 33 may be provided in the form of a plane parallel to the top surface of the rear fan assembly 100, and may be coupled to the rear fan assembly 100. At this time, the fastening plate 33 may cover the top surface of the rear fan assembly 100 and open the first discharge port 114 upward.

[0550] The fastening plate 33 can be engaged with the rear fan assembly 100 using fastening members s. As an example, the fastening members s can be provided in the form of screws. Such fastening members s can pass through the fastening plate 33 and the rear fan assembly 100 in the vertical direction and engage the fastening plate 33 with the rear fan assembly 100.

[0551] In the first state (refer to) ​ and ​ ) or second state (refer to) ​ and ​ When using cooking equipment, fastening components s can be used to combine the rear fan assembly 100 and the fastening plate 33.

[0552] In this embodiment, the lower connecting portion 35a is shown to be connected to the fastening plate 33. This lower connecting portion 35a, by connecting to the fastening plate 33, allows the guide plate 36 to be connected to the rear fan assembly 100.

[0553] As an example, the lower joint portion 35a can be formed in a form that protrudes forward from the lower end of the guide plate 36. This lower joint portion 35a can be formed as a plane parallel to the transverse plane formed by the fastening plate 33, and can be joined with the fastening plate 33 in a state where it faces the fastening plate 33 in the vertical direction.

[0554] As an example, the lower joint 35a can be joined to the fastening plate 33 by means of a fastening member s. Thus, the fastening member s can pass through the top surface of the rear fan assembly 100, the fastening plate 33, and the lower joint 35a, and join the fastening plate 33 and the lower joint 35a to the top surface of the rear fan assembly 100.

[0555] According to this embodiment, when the cooking device is manufactured in a first state or a second state or used in a first state or a second state, the rear fan assembly 100 and the fastening plate 33 can be joined by fastening members s, with the head of the fastening members s protruding towards the upper side of the fastening plate 33.

[0556] When you want to use the cooking device in this state in the third state, you can separate the fastening member s that is fastened to the rear fan assembly 100 and the fastening plate 33 from the rear fan assembly 100 and the fastening plate 33, and then use the separated fastening member s to connect the lower joint 35a to the fastening plate 33 and the rear fan assembly 100.

[0557] That is, the fastening member s used when the flow path forming member 30 is disposed on the rear fan assembly 100 can be directly used to dispose the flow path forming member 30 and the exhaust guide member 35 on the rear fan assembly 100.

[0559] ​ yes ​ Rear view of the cooking equipment ​ It is shown in magnification ​ An enlarged view of a part of the cooking equipment.

[0560] Reference ​ , ​ as well as ​ In this embodiment, the guide plate 36 may also include an upper connecting portion 35b. The upper connecting portion 35b is configured to allow the guide plate 36 to be connected to the main body 10, more specifically, to the back side of the main body 10.

[0561] The upper connecting portion 35b can be connected to the guide plate 36 on its upper side. As an example, the upper connecting portion 35b can be formed in a shape that protrudes from the upper end of the guide plate 36. This lower connecting portion 35a can be connected to the back of the main body 10, allowing the guide plate 36 to be attached to the back of the main body 10. In this embodiment, an example is shown where the upper connecting portion 35b is attached to the rear plate 15 on the upper side of the third exhaust port 4.

[0562] As an example, the upper joint 35b can extend upward from the guide plate 36 and protrude towards the rear side of the main body 10 through the third exhaust port 4. For example, the upper joint 35b can protrude towards the rear of the rear plate 15 through the third exhaust port 4. This upper joint 35b can be joined to the back of the main body 10 above the third exhaust port 4 and at the rear of the main body 10.

[0563] On the other hand, the cooking device of this embodiment may also include an adapter 7. The adapter 7 may be disposed on the back of the main body 10 and configured to connect to the pipe Da connected to the third exhaust port 4. This adapter 7 may be combined with the back of the main body 10, more specifically with the rear plate 15, from the side of the third exhaust port 4.

[0564] As an example, the adapter 7 can be provided in the form of a hollow quadrilateral frame. This adapter 7 can be provided on the back of the main body 10 in a form that protrudes rearward from the rear plate 15. The hollow formed inside the adapter 7 can communicate with the third exhaust port 4 in the front-rear direction and is formed in a shape corresponding to the shape of the third exhaust port 4.

[0565] The pipe Da can be connected to the adapter 7 by fitting it onto the outside of the adapter 7, which protrudes rearward from the back of the main body 10. With this connection between the adapter 7 and the pipe Da, the pipe Da can be positioned on the back of the cooking appliance and connected to the third exhaust port 4.

[0566] Furthermore, a damper Db can be configured inside the pipe Da. The damper Db can be connected to the adapter 7 in a manner that allows it to rotate around its upper end, and is configured to open and close the flow path formed inside the pipe Da.

[0567] like ​ As shown, the adapter 7 may include an upper protrusion 7a disposed on the hollow upper side. The upper protrusion 7a may be formed in the form of a longitudinal plate that forms a plane parallel to the rear plate 15. This upper protrusion 7a may face and contact the back surface of the main body 10 in the front-rear direction. In addition, the upper protrusion 7a may remain in close contact with the back surface of the main body 10 when the adapter 7 is attached to the back surface of the main body 10.

[0568] As one example, the upper protruding surface 7a can be in close contact with the rear panel 15. As another example, the upper protruding surface 7a can also face and contact a portion of the housing 13 that covers a portion of the back side of the rear panel 15.

[0569] The adapter 7 may also include a side protrusion 7b disposed on the hollow side. As an example, a pair of side protrusions 7b may be arranged laterally apart through the hollow. That is, side protrusions 7b may be provided on both sides of the adapter 7.

[0570] A structure for attaching the side protrusion 7b to the body 10 may be provided on the back side of the body 10. As an example, a pair of insertion portions 15a may be provided on the rear plate 15, the pair of insertion portions 15a being laterally separated by a third exhaust port 4.

[0571] As an example, each insertion portion 15a can be disposed on the outer side of the third exhaust port 4 in the lateral direction and formed in a shape that protrudes rearward from the rear plate 15. For example, the insertion portion 15a can be formed in a shape that protrudes from the rear plate 15 in an "L" shape.

[0572] An insertion space can be formed between the insertion portion 15a and the rear plate 15, which can be open to the side and upward. The side protrusion 7b can be inserted into the insertion portion 15a in a manner that allows it to be inserted into the insertion space. For example, the side protrusion 7b can be inserted into the insertion portion 15a by moving from the upper side to the lower side.

[0573] With the side protrusion 7b inserted into the insertion part 15a, a fastening member such as a screw can be used to secure them. The fastening member can pass through the side protrusion 7b and the insertion part 15a from the rear side in the front-rear direction and fix the insertion part 15a to the side protrusion 7b.

[0574] As described above, if a connection is formed between the side protrusion 7b and the insertion portion 15a, the adapter 7 can be connected to the rear plate 15, and the upper protrusion 7a can be tightly attached to the back of the main body 10. That is, the adapter 7 can be connected to the back of the main body 10 from the side of the third exhaust port 4, and the upper protrusion 7a can be tightly attached to the back of the main body 10 on the upper side of the third exhaust port 4.

[0575] As described above, the upper connecting portion 35b can be fixed between the adapter 7 provided on the back of the main body 10 and the back of the main body 10. As an example, the upper connecting portion 35b can be sandwiched between the upper protruding surface 7a and the back of the main body 10 on the upper side of the third exhaust port 4. That is, the upper connecting portion 35b can be connected to the back of the main body 10 in a form that is sandwiched between the upper protruding surface 7a and the back of the main body 10 facing each other in the front-rear direction.

[0576] The following describes an example of the installation process of the exhaust guide member 35.

[0577] Reference ​ and ​ To install the exhaust guide member 35, firstly, with the casing removed from the main body 10, the fastening member s fastened to the fastening plate 33 can be separated. Then, the fastening member s separated above can be used to attach the fastening plate 33 and the lower joint 35a together to the top surface of the rear fan assembly 100.

[0578] That is, the exhaust guide member 35 can be combined with the flow path forming member 30 to the rear fan assembly 100 by using the fastening member s used when the flow path forming member 30 is disposed on the rear fan assembly 100.

[0579] As described above, with the lower part of the exhaust guide member 35 connected to the rear fan assembly 100, such as ​ As shown, at least a portion of the exhaust guide member 35, more specifically, the upper joint 35b, can protrude outward from the body 10 through the third exhaust port 4.

[0580] Thus, the upper joint portion 35b of the third exhaust port 4 can be positioned on the rear side of the rear plate 15, and also on the upper side of the third exhaust port 4. At this time, the upper joint portion 35b can be configured to be parallel to the back surface of the main body 10.

[0581] If, in this state, the adapter 7 is attached to the rear plate 15 on the rear side of the upper joint 35b, the upper joint 35b is inserted between the back of the main body 10 and the upper protruding surface 7a of the adapter 7. The upper joint 35b, thus inserted between the main body 10 and the adapter 7, can be pressed against the back of the main body 10 and fixed to the main body 10 by the adapter 7 pressing the upper joint 35b forward.

[0582] That is, the upper part of the exhaust guide member 35 can be attached to the back of the main body 10 by the operation of setting the adapter 7 in the cooking device.

[0583] As described above, the exhaust guide member 35 of this embodiment can be effectively installed in the cooking appliance without the need for additional components. Furthermore, since the exhaust guide member 35 of this embodiment can be installed along with related components during the installation process of components required for using the cooking appliance in a third state, without requiring additional work, it has the advantage of being simple, quick, and convenient to install in the cooking appliance.

[0585] in addition, ​ This is a rear view showing the separation of the rear panel and exhaust guide members. ​ This is a front view showing the separation of the rear panel and the exhaust guide members. Additionally, ​ This is a perspective view of the rear of a cooking appliance, showing another example of an exhaust guide component. ​ It is separation ​ The rear panel and exhaust guide components are shown in the front view.

[0586] Reference ​ The guide plate 36 can be disposed inside the rear fan assembly 100. That is, in the lateral direction, the guide plate 36 can be disposed inside the rear fan assembly 100. The guide plate 36 disposed in this way can guide the flow of air discharged from the first exhaust port 114 of the rear fan assembly 100 toward the third exhaust port 4.

[0587] Reference ​ The lateral length of the guide plate 36 can be set to be less than or equal to the lateral length of the third exhaust port 4. That is, the guide plate 36 can be formed with a length that allows the third exhaust port 4 to pass through.

[0588] Reference ​ and ​ At least a portion of the guide plate 36 may be disposed on the outer side of the third exhaust port 4 in the lateral direction. That is, relative to the third exhaust port 4, the guide plate 36 may be disposed at a position offset from the lateral center C3 of the third exhaust port 4 to the other side.

[0589] As an example, a portion of the guide plate 36 may be disposed on the other side in the lateral direction of the third exhaust port 4, i.e., on the left side. In this embodiment, an example is shown where the exhaust guide member 35 also includes a side plate 36a. The side plate 36a is the portion extending laterally from the guide plate 36.

[0590] As an example, a portion of the guide plate 36 disposed on the other side of the third exhaust port 4 in the lateral direction can be equivalent to the side plate 36a. That is, the side plate 36a is the portion extending to the left from the guide plate 36 and can be disposed on the left side of the third exhaust port 4.

[0591] A notch 38c may be provided on the upper side of the side plate 36a. The notch 38c may be formed by a space surrounded by the upper end of the side plate 36a and the side end of the upper joint 35b.

[0592] As an example, the notch 38c can be formed by cutting off a portion of the upper left side of the upper joint 35b. This notch 38c can be positioned on the outside of the third exhaust port 4. That is, on the longitudinal plane formed on the back of the main body 10, the notch 38c can be located on the outside of the third exhaust port 4.

[0593] According to this embodiment, the sum of the lateral length of the guide plate 36 and the lateral length of the side plate 36a is longer than the lateral length of the upper joint portion 35b. That is, the total lateral length of the guide plate 36, including the side plate 36a, can be greater than the lateral length of the upper joint portion 35b. This is because a notch 38c is formed on the side of the upper joint portion 35b.

[0594] Furthermore, the lateral length of the upper connecting portion 35b can be less than or equal to the lateral length of the third exhaust port 4. Thus, with the guide plate 36 positioned on the front side of the rear plate 15, the upper connecting portion 35b connected to the guide plate 36 can be connected to the back side of the rear plate 15 via the third exhaust port 4.

[0595] At this time, the side plate 36a is positioned on the outer side of the third exhaust port 4 in the lateral direction, the upper joint portion 35b is positioned on the upper side of the third exhaust port 4, and the notch 38c is positioned on the upper side and the outer side of the third exhaust port 4 in the lateral direction. That is, due to the presence of the notch 38c, with the side plate 36a positioned on the outer side of the third exhaust port 4 in the lateral direction, the upper joint portion 35b can be joined to the back of the main body 10 on the rear side of the rear plate 15.

[0596] Reference ​ and ​ When the cooking equipment is used in the third state, the air expelled from the rear fan assembly 100 can flow to the side of the third exhaust port 4 through the rear guide flow path B formed by the exhaust guide member 35, and be discharged to the outside through the pipe Da connected to the third exhaust port 4.

[0597] In order to smoothly guide the airflow from the rear fan assembly 100 to the third exhaust port 4, a rear guide flow path B is preferably formed on the upper part of the rear fan assembly 100 and spans the entire lateral region of the rear fan assembly 100. For this purpose, it can be said that the exhaust guide member 35, which is preferably configured to form the rear guide flow path B, and in particular the guide plate 36, can cover most of the rear fan assembly 100 on the upper side.

[0598] One method for achieving this purpose is to form an exhaust guide member 35 in the cooking equipment such that it can completely cover the entire area of ​​the rear fan assembly 100 from above. However, the larger the size of the exhaust guide member 35, the more limited the installation space becomes. Not only does it make the installation of the exhaust guide member 35 more difficult, but there is also a risk of interference between the components constituting the flow path forming member 30 and the exhaust guide member 35.

[0599] In this embodiment, a case is illustrated where the lateral length of the rear fan assembly 100 is similar to the lateral length of the third exhaust port 4. Furthermore, a case is illustrated where the lateral length of the guide plate 36 is less than or equal to the lateral length of the third exhaust port 4.

[0600] As an example, the lateral length of the guide plate 36 can be set to a length that allows the guide plate 36 to pass through the third exhaust port 4 and to be positioned inside the rear fan assembly 100 in the lateral direction. Hereinafter, the lateral length of the guide plate 36 as described above will be referred to as the "set width".

[0601] As described above, with the rear fan assembly 100 configured, the guide plate 36, which is formed to a set width, cannot completely cover the rear fan assembly 100 on the top while simultaneously completely covering the third exhaust port 4 in the front.

[0602] The main function of the guide plate 36 is to guide the flow of air discharged from the rear fan assembly 100 toward the third exhaust port 4. Therefore, it is preferable to position the guide plate 36 so as to cover the area where air is discharged from the rear fan assembly 100, that is, above the area where the first exhaust port 114 is located.

[0603] Therefore, in this embodiment, even if the guide plate 36 cannot completely cover the third exhaust port 4 in front, the guide plate 36 should be positioned to maximize coverage of the rear fan assembly 100.

[0604] As an example, the lateral length of the rear fan assembly 100 can be set to a length corresponding to the set width, and the guide plate 36 can be disposed on the inner side of the rear fan assembly 100 in the lateral direction. Thus, the guide plate 36 can be disposed at a position offset to the left relative to the third exhaust port 4.

[0605] For example, a portion of the left side of the guide plate 36, namely the side plate 36a, is disposed on the outside of the third exhaust port 4. Furthermore, around a portion of the right side of the third exhaust port 4, there exists an area on the front side of the third exhaust port 4 that is not blocked by the guide plate 36 (hereinafter referred to as the "unblocked area").

[0606] The guide plate 36 is positioned on the left side of the outer side of the third exhaust port 4, and can effectively participate in guiding the flow of air expelled from the rear fan assembly 100 toward the third exhaust port 4.

[0607] Furthermore, the unblocked area is located in a region that is separate from the area where air is expelled from the rear fan assembly 100. Therefore, even if exhaust guidance cannot be properly achieved in this area, the resulting loss is negligible compared to the reduction in flow resistance achieved through the side plate 36a.

[0608] The exhaust guide member 35 of this embodiment is configured in a shape and size suitable for installation inside the cooking device, thereby not only making it easy to install inside the cooking device, but also effectively guiding the flow of air expelled from the rear fan assembly 100 to the third exhaust port 4.

[0609] As another example, such as ​ As shown, the exhaust guide member 350 can also cover the entire third exhaust port 4 on the front side. Such an exhaust guide member 350 can minimize the occurrence of unblocked areas and further improve the flow resistance reduction effect obtained by the side plate 36a.

[0610] On the other hand, refer to ​ In this embodiment, the third exhaust port 4 is disposed at the lateral center C1 of the main body 10. Furthermore, the rear fan assembly 100 is disposed at a position offset to the left from the lateral center C1 of the main body 10, so as to sufficiently ensure the distance between the first intake port 112 of the rear fan assembly 100 and the second exhaust port 214 of the corner fan assembly 200.

[0611] Therefore, at least a portion of the rear fan assembly 100 is disposed laterally outside the third exhaust port 4. For example, a portion of the left side of the rear fan assembly 100 may be disposed laterally outside the third exhaust port 4.

[0612] In this case, a portion of the area from which air is expelled from the rear fan assembly 100 can only be positioned laterally to the outside of the third exhaust port 4. That is, a portion of the left side of the area from which air is expelled from the rear fan assembly 100 can be positioned further to the right than the left boundary of the third exhaust port 4.

[0613] If the distance between the rear fan assembly 100 and the corner fan assembly 200 is too close, the distance between the first intake 112 and the second exhaust 214 located on the right side of the rear fan assembly 100 will also be too close. In this case, the following problems may occur: the space around the first intake 112 may be too narrow, preventing normal air intake through the first intake 112, or the space around the second exhaust 214 may be too narrow, preventing normal air exhaust through the second exhaust 214.

[0614] Therefore, in the cooking apparatus of this embodiment, the rear fan assembly 100 is positioned to the left of the center C1 in the side direction of the main body 10. That is, the rear fan assembly 100 in this embodiment can be positioned to the left of the corner fan assembly 200 relative to the center C1 in the side direction of the main body 10, rather than positioned at the center C1 in the side direction of the main body 10 or positioned to the right of the center C1 in the side direction of the main body 10.

[0615] As described above, by positioning the rear fan assembly 100 to the left of the center C1 from the side of the main body 10, the distance between the first intake port 112 located on the right side of the rear fan assembly 100 and the second exhaust port 214 located on the left side of the corner fan assembly 200 can be adequately ensured.

[0616] Therefore, although the rear fan assembly 100 is positioned more to the left relative to the third exhaust port 4, the effect obtained by ensuring adequate spacing between the rear fan assembly 100 and the corner fan assembly 200 is greater than the slight loss caused by this.

[0617] For example, the airflow from the rear fan assembly 100 to the third exhaust port 4 is slightly bent to the side, which may slightly increase the resistance to this flow. However, the resistance to the flow of air drawn in through the second intake port 212 and the resistance to the flow of air discharged through the first exhaust port 114 can be significantly reduced, thus effectively increasing the exhaust flow rate of the rear fan assembly 100 and the corner fan assembly 200.

[0618] That is, although the resistance to the airflow from the rear fan assembly 100 to the third exhaust port 4 increases slightly, the resulting effect can be fully offset by the effect of the increased exhaust flow of the rear fan assembly 100 and the corner fan assembly 200, and exhaust based on the third exhaust port 4 can be carried out more smoothly.

[0619] In addition, in this embodiment, an exhaust guide member 35 is provided between the air exhaust side of the rear fan assembly 100 and the third exhaust port 4, thereby enabling more effective guidance of the flow of exhaust based on the third exhaust port 4.

[0620] The exhaust guide member 35 can block the passage between the air supply sections 100 and 200 and the upper space section 10i while forming a passage to guide the flow of air discharged from the air supply sections 100 and 200 toward the third exhaust port 4, namely the rear guide flow path B. This exhaust guide member 35 not only reduces the flow resistance around the third exhaust port 4, but also helps to smoothly guide the exhaust flow from the air supply sections 100 and 200 toward the third exhaust port 4.

[0621] That is, in the cooking device of this embodiment, by ensuring sufficient spacing between the rear fan assembly 100 and the corner fan assembly 200, the exhaust flow of the air supply units 100 and 200 is effectively increased, and the exhaust flow from the air supply units 100 and 200 to the third exhaust port 4 is effectively guided by the exhaust guide member 35, thereby making the exhaust based on the third exhaust port 4 smoother and providing a fume extraction function with further improved performance.

[0622] It should be understood that although the present invention has been described with reference to the accompanying drawings, this is merely exemplary, and those skilled in the art can implement various modifications and equivalent embodiments therein. Therefore, the true scope of protection of the present invention should be determined by the appended claims.
