Description

Technical Field

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

[0002] With the development of technology, cooking equipment has incorporated a large number of electronic components. Many of these components are highly sensitive to temperature; excessively high temperatures can cause performance degradation or even damage. To prevent these components from being affected by excessive heat, cooking equipment typically features cooling ducts and fans. During operation, cool outside air flows through the cooling ducts to dissipate the heat generated by the cooking equipment, preventing overheating near the electronic components and ensuring their stable operation at a suitable temperature.

[0003] In traditional cooking appliances, air vents are typically installed on the door or cabinet to allow cold outside air to enter the cooling duct. Driven by a cooling fan, this cold air continuously flows into the duct. However, these air vents, specifically designed to bring in cold outside air, provide new hiding places for dirt and grime, increasing the difficulty of cleaning for users. Utility Model Content

[0004] Therefore, it is necessary to provide a cooking device to address the above problems.

[0005] To address the above problems, this application provides the following technical solution:

[0006] A cooking device comprising:

[0007] Box;

[0008] An inner liner is fixedly disposed within the box body, and the inner liner has a cooking cavity;

[0009] A hinge has a first housing, a second housing, and a rotating assembly. The first housing has a first receiving cavity, and the second housing has a second receiving cavity. The rotating assembly includes a first connecting rod and a second connecting rod rotatably connected to the first connecting rod. The first connecting rod is partially fixed within the first receiving cavity, and the second connecting rod is partially fixed within the second receiving cavity. The first housing has a clearance channel, and the second connecting rod is located within the clearance channel. The first housing is fixed to the housing body.

[0010] A door is fixedly mounted on the second housing, and the door is rotatably connected to the housing via the hinge to open and close the cooking cavity;

[0011] A heat dissipation duct, connected to the housing, has a first air inlet and a first air outlet; and

[0012] A cooling fan, connected to the cooling duct, is used to generate an airflow from the first air inlet to the first air outlet;

[0013] The first housing is also provided with a vent, and the first air inlet, the vent, the first accommodating cavity and the clearance channel are connected in sequence. The clearance channel is located near the outer wall of the housing and is visible from the outside of the housing.

[0014] This cooking equipment has at least the following beneficial effects:

[0015] During the operation of the cooling fan, outside cold air sequentially enters the cooling duct through the clearance channel, the first accommodating cavity, the vent, and the first air inlet. In other words, this cooking appliance utilizes the clearance channel, designed to facilitate the rotation of the second connecting rod relative to the first connecting rod, to introduce outside cold air into the cooling duct. This eliminates the need for a dedicated air inlet on the door or cabinet for outside cold air to enter the cooling duct, reducing the accumulation points of dirt and simplifying cleaning for the user.

[0016] In one embodiment, the first housing is further provided with an air intake, which connects the first accommodating cavity to the outside, and the air intake is located near the avoidance channel.

[0017] This configuration, with the air intake positioned close to the clearance channel, ensures that the air near the air intake is also relatively cold. This allows cold outside air to sequentially pass through the air intake, the first accommodating cavity, the vent, and the first air inlet into the heat dissipation duct. This facilitates the entry of more cold air into the heat dissipation duct, enhances airflow within it, and helps maintain the heat dissipation efficiency of the cooking equipment.

[0018] In one embodiment, the first accommodating cavity is connected to the outside only through the avoidance channel, the air intake, and the air vent.

[0019] This design ensures that the air entering the heat dissipation duct through the first accommodating cavity and the vent is relatively cold, which helps to ensure the heat dissipation efficiency of the cooking equipment.

[0020] In one embodiment, the first housing is located at the lower part of the box, and the clearance passage is at least partially located near the bottom wall of the box.

[0021] This design helps ensure that the air entering the heat dissipation duct through the clearance channel is relatively cool, which helps ensure the heat dissipation efficiency of the cooking equipment.

[0022] In one embodiment, the first housing is located above the bottom wall of the enclosure, and the clearance channel extends through the first housing in a vertical direction, with the portion of the clearance channel located on the bottom side of the first housing visible from the outside of the enclosure.

[0023] This design has two advantages. First, it leaves a certain space between the first shell and the bottom wall of the cabinet, allowing outside cold air to smoothly enter the clearance channel even when the cooking equipment is placed in a cabinet or on a countertop, thus ensuring the heat dissipation efficiency of the cooking equipment. Second, it gives the clearance channel a downward-facing opening, and since colder air is located at a lower position, this facilitates drawing lower-positioned cold air into the heat dissipation duct through the clearance channel.

[0024] In one embodiment, the heat dissipation duct is located above the first housing.

[0025] With this configuration, natural convection helps the cold air in the first accommodating cavity to flow upward into the heat dissipation duct after being heated, which helps reduce the burden on the cooling fan and saves energy.

[0026] In one embodiment, the rotating component is made of stainless steel.

[0027] This design prevents the rotating components from rusting, thus ensuring the lifespan of the hinge.

[0028] In one embodiment, the cooking device further includes an extended air duct having a second air inlet and a plurality of second air outlets, each of the second air outlets being connected to the first air outlet through the second air inlet.

[0029] With this configuration, the air in the heat dissipation duct can be blown to different parts of the cooking equipment through multiple second air outlets, enabling targeted heat dissipation for different parts of the cooking equipment.

[0030] In one embodiment, the cooking apparatus further includes a lighting device for illuminating the cooking cavity; one of the second air vents is disposed toward the lighting device.

[0031] This design allows for targeted heat dissipation of the lighting equipment, which helps ensure the lifespan of the lighting equipment.

[0032] In one embodiment, the cooking device further includes a high-voltage capacitor and a gas vent, one end of which is connected to a second gas outlet, and the other end of which is disposed toward the high-voltage capacitor.

[0033] This configuration allows for targeted heat dissipation of the high-voltage capacitor, which helps ensure its normal operation and extends its service life. Attached Figure Description

[0052] See Figures 1 to 10 This application provides a cooking device, which includes a housing 1, an inner liner 2, a hinge 3, a door 4, a heat dissipation duct 5, and a heat dissipation fan 6. The inner liner 2 is fixed inside the housing 1 and has a cooking cavity 21. The hinge 3 has a first housing 31, a second housing 32, and a rotating assembly 33. The first housing 31 has a first receiving cavity 311, and the second housing 32 has a second receiving cavity 321. The rotating assembly 33 includes a first connecting rod 331 and a second connecting rod 332 rotatably connected to the first connecting rod 331. The first connecting rod 331 is partially fixed inside the first receiving cavity 311, and the second connecting rod 332 is partially fixed inside the second receiving cavity 321. To facilitate the rotation of the second connecting rod 332 relative to the first connecting rod 331, the first housing 31 has a clearance channel 312, and the second connecting rod 332 is partially located inside the clearance channel 312. The first housing 31 is fixed to the housing 1. Door 4 is fixed to the second housing 32 and is rotatably connected to the cabinet 1 via hinge 3 to open and close the cooking cavity 21. A heat dissipation duct 5 is connected to the cabinet 1 and has a first air inlet 51 and a first air outlet 52. A heat dissipation fan 6 is connected to the heat dissipation duct 5 to generate airflow from the first air inlet 51 to the first air outlet 52. The first housing 31 is also provided with a vent 313. The first air inlet 51, vent 313, first accommodating cavity 311, and clearance channel 312 are sequentially connected. The clearance channel 312 is located near the outer wall of the cabinet 1 and is visible from the outside of the cabinet 1.

[0053] This cooking equipment has at least the following beneficial effects:

[0054] During the operation of the cooling fan 6, cold air from the outside enters the cooling duct 5 sequentially through the clearance channel 312, the first accommodating cavity 311, the vent 313, and the first air inlet 51. In other words, this cooking device utilizes the clearance channel 312, which is designed to facilitate the rotation of the second connecting rod 332 relative to the first connecting rod 331, to introduce cold air from the outside into the cooling duct 5. This eliminates the need for a dedicated air inlet on the door 4 or the cabinet 1 to allow cold air to enter the cooling duct 5, reducing the points where dirt can accumulate and simplifying cleaning for the user.

[0055] See Figure 9The first housing 31 is also provided with an air intake 314, which connects the first accommodating cavity 311 to the outside. The air intake 314 is located near the clearance channel 312. Because the air intake 314 is located near the clearance channel 312, the air near the air intake 314 is also relatively cold. In this way, cold air from the outside can also enter the heat dissipation duct 5 in sequence through the air intake 314, the first accommodating cavity 311, the vent 313, and the first air inlet 51. This is conducive to more cold air entering the heat dissipation duct 5, which helps to enhance the airflow in the heat dissipation duct 5 and helps to ensure the heat dissipation efficiency of the cooking equipment.

[0056] Preferably, the first accommodating cavity 311 is connected to the outside world only through the avoidance channel 312, the air intake 314, and the air vent 313. In other words, when the avoidance channel 312, the air intake 314, and the air vent 313 are all blocked, the first accommodating cavity 311 is a sealed space. This ensures that the air entering the heat dissipation duct 5 through the first accommodating cavity 311 and the air vent 313 is relatively cool air, which is beneficial to ensuring the heat dissipation efficiency of the cooking equipment.

[0057] See Figure 4 and Figure 5 The first housing 31 is located at the lower part of the cabinet 1, and the clearance channel 312 is at least partially located close to the bottom wall of the cabinet 1. This helps to ensure that the air entering the heat dissipation duct 5 through the clearance channel 312 is relatively cool air, which helps to ensure the heat dissipation efficiency of the cooking equipment.

[0058] See Figure 4 and Figure 5 The first housing 31 is located above the bottom wall of the cabinet 1, and the clearance channel 312 runs vertically through the first housing 31. The portion of the clearance channel 312 located on the bottom side of the first housing 31 is visible from the outside of the cabinet 1. On the one hand, a certain space is left between the first housing 31 and the bottom wall of the cabinet 1, allowing outside cold air to smoothly enter the clearance channel 312 when the cooking equipment is placed in a cabinet or countertop, which helps ensure the heat dissipation efficiency of the cooking equipment. On the other hand, this gives the clearance channel 312 a downward opening, and since colder air is located at a lower position, this facilitates the intake of lower-positioned cold air into the heat dissipation duct 5 through the clearance channel 312.

[0059] In natural convection, cold air rises after being heated. (See also...) Figure 6 The heat dissipation duct 5 is located above the first housing 31. In this way, natural convection helps the cold air in the first accommodating cavity 311 to flow upward into the heat dissipation duct 5 after being heated, which helps to reduce the burden on the cooling fan 6 and saves energy.

[0060] Preferably, the rotating component 33 is made of stainless steel. This prevents the rotating component 33 from rusting, which helps ensure the service life of the hinge 3. In other embodiments, the rotating component 33 may also be made of high-temperature resistant plastic.

[0061] See Figure 6 and Figure 7 The cooking equipment also includes an extended air duct 7, which has a second air inlet 71 and multiple second air outlets 72. Each second air outlet 72 is connected to a first air outlet 52 through the second air inlet 71. In this way, air in the heat dissipation air duct 5 can be blown to different parts of the cooking equipment through the multiple second air outlets 72, enabling targeted heat dissipation for different parts of the cooking equipment.

[0062] In some embodiments, the cooking appliance further includes a lighting device for illuminating the cooking cavity 21, wherein a second air outlet 72 is disposed toward the lighting device. This allows for targeted heat dissipation of the lighting device, which helps to ensure the lifespan of the lighting device.

[0063] See Figure 6 and Figure 7 The cooking device also includes a high-voltage capacitor (not shown in the figure) and a vent pipe 8. One end of the vent pipe 8 is connected to a second vent 72, and the other end of the vent pipe 8 is positioned towards the high-voltage capacitor. This allows for targeted heat dissipation of the high-voltage capacitor, which helps ensure its normal operation and extends its service life.

[0064] 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.

[0065] 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.
