Description

Technical Field

[0001] This application relates to the field of kitchenware technology, and in particular to cooking equipment. Background Technology

[0002] Steam ovens, regular ovens, steam ovens, and microwave-steam-oven combos all include an inner cavity and a door assembly. The inner cavity has a cooking chamber where food is placed and cooked, and the door assembly is used to open and close the cooking chamber. The door assembly includes the door body and a handle. During cooking, a large amount of heat is generated inside the inner cavity, and some of this heat is transferred to the door body and handle, causing them to heat up. If the door body and handle are allowed to heat up too much, there is a risk of burns to the user. Specifically, after cooking, the user will apply force to the handle to open the cooking chamber and remove the food; if the handle has not cooled down sufficiently, it can burn the user. During cooking, the user may accidentally come into contact with the door body or handle, which can also cause burns. Utility Model Content

[0003] Therefore, it is necessary to provide a cooking device to address the above problems.

[0004] To address the above problems, this application provides the following technical solution:

[0005] A cooking device comprising:

[0006] Box;

[0007] An inner liner is provided in the box body, and the inner liner has a cooking cavity;

[0008] A door assembly is movably connected to the housing for opening and closing the cooking cavity; the door assembly is provided with a cold air channel, the cold air channel having a cold air inlet and a cold air outlet; the door assembly includes a door body and a handle, the handle being located at the upper part of the door body, the cold air inlet being located at the handle and communicating with the outside, and the cold air outlet being located at the lower part of the door body;

[0009] A heat dissipation duct is provided in the housing, the duct having an air inlet and an air outlet. The air inlet is located below the inner liner, near and connected to the cold air outlet, and the air outlet is connected to the outside.

[0010] A cooling fan is provided in the cooling duct to generate airflow from the air inlet to the air outlet.

[0011] This cooking equipment has at least the following beneficial effects:

[0012] Because the air inlet is close to and connected to the cold air outlet, during the operation of the cooling fan, outside cold air flows into the cold air channel through the cold air inlet, then sequentially flows into the cooling duct through the cold air outlet and air inlet, and finally is exhausted to the outside through the air outlet. In other words, during the operation of the cooling fan, outside cold air continuously enters and exits the handle and door, dissipating heat from them and preventing burns to the user. Furthermore, this cold air also flows through the cooling duct, further cooling the cooking equipment and preventing the electronic components inside from being exposed to excessively high temperatures for extended periods, thus protecting these components.

[0013] In one embodiment, when the door assembly closes the cooking cavity, the distance between the cold air outlet and the air inlet is less than or equal to 5 mm.

[0014] This design allows the cooling fan to draw air out of the cold air duct, ensuring a continuous flow of cold air from the outside into the handle and door, which helps the handle and door to dissipate heat effectively.

[0015] In one embodiment, with the door assembly closed in the cooking chamber, the cold air outlet faces the air inlet.

[0016] This design allows the cooling fan to draw air out of the cold air duct, ensuring a continuous flow of cold air from the outside into the handle and door, which helps the handle and door to dissipate heat effectively.

[0017] In one embodiment, both the cold air outlet and the air inlet are elongated.

[0018] This design facilitates the removal of cold air from the cold air duct, which helps the handle and door to dissipate heat effectively.

[0019] In one embodiment, the handle is provided with an air inlet area, which is elongated and has multiple cold air inlets that are evenly distributed in the air inlet area, and the diameter of each cold air inlet is less than or equal to 2 mm.

[0020] This design serves two purposes: firstly, it facilitates the entry of cold air from the outside into the cold air duct, promoting good heat dissipation for the handle and door. Secondly, it prevents impurities from the outside from entering the handle and door through the cold air inlet.

[0021] In one embodiment, the handle has a blind hole, and the cold air inlet is located on the wall of the blind hole near the door body, with the opening of the blind hole facing downwards.

[0022] This design serves two purposes: firstly, it ensures that only cold air is drawn in through the air inlet; secondly, it helps prevent external impurities from reaching the air inlet and entering the handle and door body through it.

[0023] In one embodiment, the heat dissipation duct includes a first section and a second section that are interconnected. The first section is located below the inner liner, and the second section is located behind the inner liner. The air inlet is located in the first section, and the air outlet is located in the second section. The heat dissipation fan is located in the first section. The inner liner is provided with a first air outlet, and the second section is provided with a first air inlet. The cooking device also includes an exhaust pipe, and the two ends of the exhaust pipe are respectively connected to the first air inlet and the first air outlet to connect the first air inlet and the first air outlet.

[0024] This design serves two purposes. First, it allows moisture that needs to be expelled from the inner liner to enter the second section through the first air outlet and the first air inlet, and then be discharged to the outside with the airflow within the cooling duct. Second, it keeps the cooling fan away from the first air inlet, and along the airflow direction within the cooling duct, the cooling fan is located behind the first air inlet. Both of these factors help prevent moisture entering the cooling duct from the first air inlet from contacting the cooling fan, thus protecting the cooling fan.

[0025] In one embodiment, the second section is further provided with a second air outlet, the inner pot is further provided with a second air inlet, the cooking device further includes an air inlet pipe and a cover plate, the two ends of the air inlet pipe are respectively connected to the second air inlet and the second air outlet so that the second air inlet and the second air outlet are connected; the cover plate is movably connected to the second section and is used to open and close the second air outlet.

[0026] With this design, after cooking, the cover can be removed to open the second vent, allowing some of the gas in the second section to enter the inner pot through the second vent and the second inlet, which helps to accelerate the release of gas and heat from the inner pot. During cooking, the cover can be used to close the second vent, preventing gas in the second section from entering the inner pot through the second vent and the second inlet and interfering with the normal cooking environment inside the inner pot.

[0027] In one embodiment, the cooking device further includes a centrifugal fan and an anti-backflow pipe. The centrifugal fan includes a rotating shaft and fan blades. The rotating shaft is rotatably connected to the inner liner, and the fan blades are fixed to the rotating shaft and located inside the inner liner. The anti-backflow pipe extends from the edge of the second air inlet toward the inner liner. The end of the anti-backflow pipe away from the second air inlet is a first pipe opening, and the orientation of the first pipe opening is parallel to the axial direction of the rotating shaft.

[0028] This design prevents backflow through the anti-backflow pipe, blocking the airflow generated by the centrifugal fan inside the inner liner from entering the second air inlet. After cooking, with the second air outlet open, it is also difficult for the airflow generated by the centrifugal fan inside the inner liner to flow back into the second section through the second air inlet and outlet.

[0029] In one embodiment, the end of the anti-backflow pipe away from the second air inlet is entirely located within a first plane, which is perpendicular to the rotation axis.

[0030] With this configuration, the rotating shaft is horizontal, and the first plane is vertical. This helps prevent backflow by blocking the airflow generated by the centrifugal fan inside the inner liner from the second air inlet. This ensures that even after cooking is complete and the second air outlet is open, the airflow generated by the centrifugal fan inside the inner liner is unlikely to backflow into the second section through the second air inlet and outlet.

[0057] See Figures 1 to 18 This application provides a cooking device, which includes a housing 1, an inner liner 2, a door assembly 3, a heat dissipation duct 4, and a heat dissipation fan 5. The inner liner 2 is located within the housing 1 and has a cooking cavity 21 in which food is placed for cooking. The door assembly 3 is movably connected to the housing 1 and is used to open and close the cooking cavity 21. The door assembly 3 has a cold air duct 31, which has a cold air inlet 311 and a cold air outlet 312. The door assembly 3 includes a door body 32 and a handle 33. The handle 33 is located at the upper part of the door body 32, the cold air inlet 311 is located on the handle 33 and communicates with the outside, and the cold air outlet 312 is located at the lower part of the door body 32. The heat dissipation duct 4 is located within the housing 1 and has an air inlet 41 and an air outlet 42. The air inlet 41 is located below the inner liner 2, is positioned near and communicates with the cold air outlet 312, and the air outlet 42 communicates with the outside. The cooling fan 5 is located in the cooling air duct 4 and is used to generate airflow from the air inlet 41 to the air outlet 42.

[0058] Because the air inlet 41 is close to and connected to the cold air outlet 312, during the operation of the cooling fan 5, outside cold air flows into the cold air channel 31 through the cold air inlet 311 and then sequentially flows into the cooling air duct 4 through the cold air outlet 312 and the air inlet 41, before being discharged to the outside through the air outlet 42. In other words, during the operation of the cooling fan 5, outside cold air continuously enters and exits the handle 33 and the door 32, which dissipates heat from the handle 33 and the door 32, preventing the handle 33 and the door 32 from burning the user. Moreover, the aforementioned cold air can also flow through the cooling air duct 4, which can dissipate heat from the cooking equipment, preventing the electronic components in the cooking equipment from being exposed to excessively high temperatures for extended periods, thus protecting the electronic components in the cooking equipment.

[0059] For example, the cooking equipment is a steam oven / oven / steam oven / microwave-steam-grill combination / stove-steam-grill combination.

[0060] In some embodiments, the door assembly 3 is rotatably connected to the housing 1. In other embodiments, the door assembly 3 is slidably connected to the housing 1.

[0061] Preferably, with the door assembly 3 closed and the cooking cavity 21 closed, the distance between the cold air outlet 312 and the air inlet 41 is less than or equal to 5 mm. This facilitates the cooling fan 5 in drawing air out of the cold air channel 31, ensuring a continuous flow of cold air from the outside into the handle 33 and the door 32, which is beneficial for the handle 33 and the door 32 to achieve good heat dissipation.

[0062] For example, the distance between the cold air outlet 312 and the air inlet 41 is 3.5 mm.

[0063] Combination Figure 1 , Figure 13 , Figure 14 and Figure 15 With the door assembly 3 closed and the cooking cavity 21 closed, the cold air outlet 312 is directly opposite the air inlet 41. This allows the cooling fan 5 to draw air out of the cold air passage 31, ensuring a continuous flow of cold air from the outside into the handle 33 and the door 32, which is beneficial for the handle 33 and the door 32 to dissipate heat effectively.

[0064] See Figure 8 and Figure 15 Both the cold air outlet 312 and the air inlet 41 are elongated. This facilitates the exit of cold air from the cold air channel 31 and helps the handle 33 and the door 32 to dissipate heat effectively.

[0065] Combination Figure 3 , Figure 4 , Figure 9 and Figure 10 The handle 33 is provided with an air inlet area 3311, which is elongated. Multiple cold air inlets 311 are evenly distributed within the air inlet area 3311, with each cold air inlet having a diameter of less than or equal to 2 mm. On one hand, this facilitates the entry of outside cold air into the cold air channel 31, promoting good heat dissipation for the handle 33 and the door 32. On the other hand, this prevents external impurities from entering the handle 33 and the door 32 through the cold air inlets 311.

[0066] For example, the diameter of each cold air inlet 311 is 1.5 mm.

[0067] It's understandable that heated air rises; in other words, cold air is at the bottom and warm air is at the top. Combined with... Figure 1 , Figure 3 and Figure 9 The handle 33 has a blind hole 331, and a cold air inlet 311 is located on the wall of the blind hole 331 near the door body 32, with the opening of the blind hole 331 facing downwards. On the one hand, this ensures that the cold air inlet 311 draws in cold air. On the other hand, this helps prevent external impurities from reaching the cold air inlet 311 and from entering the handle 33 and the door body 32 through the cold air inlet 311.

[0068] See Figure 13 and Figure 15 The heat dissipation duct 4 includes a first section 43 and a second section 44 that are interconnected. The first section 43 is located below the inner liner 2, and the second section 44 is located behind the inner liner 2. An air inlet 41 is located in the first section 43, and an air outlet 42 is located in the second section 44. A heat dissipation fan 5 is located in the first section 43. The inner liner 2 has a first air outlet 22, and the second section 44 has a first air inlet 441. The cooking equipment also includes an exhaust pipe 6, with its two ends connected to the first air inlet 441 and the first air outlet 22, respectively, so that the first air inlet 441 and the first air outlet 22 are connected. On the one hand, this allows moisture that needs to be discharged from the inner liner 2 to enter the second section 44 through the first air outlet 22 and the first air inlet 441, and then be discharged to the outside with the airflow in the heat dissipation duct 4. On the other hand, this keeps the cooling fan 5 away from the first air inlet 441, and along the flow direction of the airflow in the cooling duct 4, the cooling fan 5 is located behind the first air inlet 441. Both of these factors help prevent moisture entering the cooling duct 4 from the first air inlet 441 from contacting the cooling fan 5, which helps protect the cooling fan 5.

[0069] See Figure 13 and Figure 15 The second section 44 also has a second air outlet 442. (See reference...) Figure 18 The inner liner 2 also has a second air inlet 23. (See reference...) Figure 7 and Figure 13 The cooking equipment also includes an air inlet pipe 7 and a cover plate 8. The two ends of the air inlet pipe 7 are connected to a second air inlet 23 and a second air outlet 442, respectively, to connect the second air inlet 23 and the second air outlet 442. The cover plate 8 is movably connected to the second section 44 and is used to open and close the second air outlet 442. Thus, after cooking, the cover plate 8 can be removed to open the second air outlet 442, allowing some gas from the second section 44 to enter the inner pot 2 through the second air outlet 442 and the second air inlet 23, which helps to accelerate the discharge of gas and heat from the inner pot 2. During cooking, the cover plate 8 can be used to cover the second air outlet 442 to close it, preventing gas from the second section 44 from entering the inner pot 2 through the second air outlet 442 and the second air inlet 23 and interfering with the normal cooking environment inside the inner pot 2.

[0070] See Figure 7 and Figure 15The cooking device includes a drive assembly 20, which includes a drive motor 201, a gear 202, and a rack 203. The drive motor 201 has an output shaft 2011 capable of outputting forward and reverse rotation. The gear 202 is fixed to the output shaft 2011. The rack 203 is slidably connected to the second section 44 and meshes with the gear 202. The cover plate 8 is fixedly connected to the rack 203. When the drive motor 201 is working, the output shaft 2011 and the gear 202 rotate, thereby driving the rack 203 and the cover plate 8 to move linearly to open and close the second air outlet 442.

[0071] In some embodiments, the drive assembly 20 is an electric push rod, and the cover plate 8 is fixedly connected to the push rod of the drive assembly 20.

[0072] In some embodiments, the cover plate 8 is rotatably connected to the second section 44, and the drive assembly 20 drives the cover plate 8 to rotate to open and close the second air outlet 442.

[0073] See Figure 17 The cooking equipment also includes a centrifugal fan 9 and an anti-backflow pipe 10. The centrifugal fan 9 includes a rotating shaft 91 and fan blades 92. The rotating shaft 91 is rotatably connected to the inner liner 2, and the fan blades 92 are fixed to the rotating shaft 91 and located inside the inner liner 2. The anti-backflow pipe 10 extends from the edge of the second air inlet 23 toward the inner liner 2. The end of the anti-backflow pipe 10 away from the second air inlet 23 has a first port 101, and the orientation of the first port 101 is parallel to the axial direction of the rotating shaft 91. In this way, the anti-backflow pipe 10 can block the airflow generated by the centrifugal fan 9 inside the inner liner 2 from the second air inlet 23. After cooking, with the second air outlet 442 open, it is also difficult for the airflow generated by the centrifugal fan 9 inside the inner liner 2 to backflow into the second section 44 through the second air inlet 23 and the second air outlet 442.

[0074] See Figure 17 The end of the anti-backflow pipe 10 furthest from the second air inlet 23 is entirely located within the first plane, which is perpendicular to the rotation axis 91. For example, see [reference needed]. Figure 17 The rotating shaft 91 is horizontally positioned, and the first plane is vertical. This helps the anti-backflow pipe 10 to block the airflow generated by the centrifugal fan 9 inside the inner liner 2 from the second air inlet 23. This helps ensure the following effect: after cooking, with the second air outlet 442 open, it is difficult for the airflow generated by the centrifugal fan 9 inside the inner liner 2 to backflow into the second section 44 through the second air inlet 23 and the second air outlet 442.

[0075] See Figure 17In order to facilitate the discharge of gas inside the inner liner 2 by the centrifugal fan 9, the centrifugal fan 9 is located on the back side of the inner liner 2. A part of the back side of the inner liner 2 is recessed downwards. The recessed part on the back side of the inner liner 2 and the part on the back side of the inner liner 2 that is not recessed downwards are connected by a slope 24. The first air outlet 22 is at least partially located on the slope 24.

[0076] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the appended claims.
