Description

Technical Field

[0001] This utility model relates to the field of cooking utensil technology, and more specifically, to a cooking utensil. Background Technology

[0002] Currently, cooking appliances with air-frying functions use a fan to drive airflow within the cooking chamber. This airflow passes through the heating element, transferring heat from the element to the food's surface. A small portion of the heat is also radiated to the food's surface via the heating element. Finally, the heat from the food's surface is transferred to the interior through heat conduction, thus cooking the food. However, during the cooking process, the heat transferred to the food via convection causes rapid evaporation of moisture, resulting in a less desirable texture and taste.

[0003] In related technologies, during the cooking process, in order to reduce the rate of moisture evaporation from the food, the airflow speed inside the cooking cavity is reduced, thereby reducing the heat transferred to the food through thermal convection. However, reducing the airflow speed inside the cooking cavity will cause the heating element to heat up faster, thus reducing the stability of the heating element during operation. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the first aspect of this utility model proposes a cooking utensil.

[0006] In view of the above, the first aspect of the present invention provides a cooking appliance, including a body, a heating element, a fan blade, and a heat dissipation assembly; the body is provided with a cooking cavity; the heating element is disposed on one side of the cooking cavity; the fan blade is disposed on the side of the heating element away from the cooking cavity, for driving airflow through the heating element and into the cooking cavity; the heat dissipation assembly is disposed on the body for dissipating heat from the heating element.

[0007] The cooking appliance provided by this utility model includes a main body with a cooking cavity for holding food ingredients, allowing the appliance to cook the ingredients. The appliance also includes a heating element disposed on one side of the cooking cavity. The heat generated by the heating element is transferred to the food ingredients placed inside the cooking cavity via thermal radiation, thereby cooking the food. The appliance further includes fan blades disposed on the side of the heating element away from the cooking cavity. The fan blades drive airflow past the heating element, thereby transferring heat to the food ingredients via thermal convection, thus cooking the food.

[0008] The cooking appliance also includes a heat dissipation component, which is located on the main body and used to dissipate heat from the heating element. When cooking food with a cooking appliance equipped with a heat dissipation component, the airflow speed inside the cooking chamber can be reduced by decreasing the fan blade speed. This reduces the proportion of heat generated by the heating element transferred to the food through thermal convection and increases the proportion of heat transferred to the food through thermal radiation. This reduces the rate of moisture evaporation during the cooking process, especially effectively reducing the rate of moisture evaporation from the inside of the food, resulting in food that is crispy on the outside and tender on the inside, reducing the probability of the food being too dry and improving its taste. At the same time, during the cooking process, the heat dissipation component dissipates heat from the heating element. Even with a low fan blade speed and a slow airflow speed inside the cooking chamber, the heat generated by the heating element is dissipated by the heat dissipation component, reducing the heating rate and temperature of the heating element. This reduces the probability of damage to the heating element due to excessive heat or rapid heating, and improves the stability of the heating element during the cooking process.

[0009] Furthermore, the heat dissipation component dissipates heat from the heating element, allowing the heat dissipation component to turn on or off according to the temperature of the heating element. This enables the heat dissipation component to control the temperature of the heating element, improve the temperature stability of the heating element during cooking, and further enhance the taste of the food cooked by the cooking appliance.

[0010] The fan blades are positioned on the side of the heating element away from the cooking cavity, meaning the heating element is positioned on the side of the fan blades closer to the cooking cavity. The heating element is positioned as close to the cooking cavity as possible to shorten the heat radiation distance between the heating element and the food inside the cooking cavity, thereby enhancing the effect of radiative heat transfer.

[0011] Specifically, the cooking appliance provided in this application heats food by enhancing radiative heat transfer and reducing convective heat transfer, thereby reducing the impact of convective heat transfer on the loss of moisture from the food, and improves the stability of the heating element's operation by using a heat dissipation component to dissipate heat from the heating element.

[0012] Specifically, the heating element is a heating tube, a heating plate, or a heating wire.

[0013] Optionally, the heat dissipation component is located on the circumferential outer side of the heating element.

[0014] The heating element is installed below the fan blades.

[0015] Alternatively, the cooking appliance can be an air fryer or a steam oven.

[0016] In some technical solutions of this utility model, the heat dissipation component is a heat dissipation fan, which is provided with a first air outlet facing the heating component, and is used to drive the airflow to flow to the area outside the cooking cavity after passing through the heating component.

[0017] In this technical solution, the heat dissipation component is a cooling fan with a first air outlet facing the heating element. This air outlet drives airflow through the heating element, carrying away heat generated by the element and increasing its heat dissipation rate. This reduces the temperature rise rate and overall temperature of the heating element, thus achieving effective heat dissipation. After passing the heating element, the airflow flows to areas outside the cooking cavity, minimizing the impact of the hot airflow from the cooling fan on the food inside the cooking cavity and further improving the taste of the cooked food.

[0018] Specifically, the cooling fan can drive airflow to flow radially along the heating element, that is, the cooling fan drives the airflow to pass horizontally through the heating element, the airflow flows from one side of the heating element to the other side of the heating element, and is discharged to the outside of the cooking appliance.

[0019] The cooling fan can also drive the airflow to flow away from the cooking cavity. That is, the cooling fan drives the airflow from the side of the heating element that is close to the cooking cavity to the side of the heating element that is away from the cooking cavity. The airflow can flow to the cooling cavity of the cooking appliance and then flow to the outside of the cooking appliance.

[0020] Optionally, the casing and fan blades of the cooling fan can be made of materials with a temperature resistance of 200 degrees Celsius or higher.

[0021] Optionally, the heating element is a heating element, and the cooling fan is located around the heating element. Reducing heat transfer through convection can be achieved by slowing down the fan blade speed. However, if the surface temperature of the heating element becomes too high, there is a risk of the element bursting, and it will also affect the temperature rise of some electrical components above the heating element. Installing a cooling fan near the heating element can lower its surface temperature and prevent the area around the heating element from becoming too hot.

[0022] In some technical solutions of this utility model, the main body is provided with a second air vent, which is located on the side of the heating component away from the heat dissipation fan, and the cooking cavity is connected to the outside of the main body through the second air vent.

[0023] In this technical solution, the main body is provided with a second air vent, which is located on the side of the heating component away from the heat dissipation fan. The cooking cavity is connected to the outside of the main body through the second air vent. When the heat dissipation fan drives the airflow from the side of the heating component close to the heat dissipation fan to the side of the heating component away from the heat dissipation fan, the airflow that moves to the side of the heating component away from the heat dissipation fan will be discharged from the cooking cavity through the second air vent, thereby reducing the impact of the hot airflow generated by the heat dissipation fan on the food in the cooking cavity.

[0024] The main body is equipped with a second air vent, which is located on the side of the heating element away from the cooling fan. The cooking cavity is connected to the outside of the main body through the second air vent. When the cooling fan drives the airflow from the side of the heating element away from the cooling fan to the side of the heating element close to the cooling fan, the gas outside the cooking appliance enters the cooking cavity through the second air vent and is then discharged from the cooking cavity by the cooling fan, thereby reducing the impact of the hot airflow generated by the cooling fan on the food inside the cooking cavity.

[0025] Specifically, the cooling fan is an axial flow fan or a centrifugal fan.

[0026] The cooling fan is either an exhaust fan or a blower.

[0027] The main body is equipped with a third air vent, which is connected to the first air vent of the cooling fan. The third and second air vents are located on opposite sides of the heating element in the radial direction. The cooling fan drives airflow from the second air vent through the heating element to the third air vent, or vice versa. The third and second air vents are directly opposite each other, which allows the heat near the heating element to be quickly exhausted through the second air vent, preventing slow heat dissipation near the heating element. Furthermore, the third air vent facing the second air vent avoids direct contact with the baking pan, reducing the impact of heat transfer from the cooling fan on the rapid moisture loss of the food on the baking pan.

[0028] In some technical solutions of this utility model, the cooking appliance also includes a temperature detection component, which is disposed between the second air vent and the heating component.

[0029] In this technical solution, the cooking appliance also includes a temperature detection component, which is located between the second air vent and the heating component. The temperature detection component can detect the temperature of the airflow passing through it. The temperature of the airflow passing through the temperature detection component can be used to control the opening and closing of the cooling fan, thereby controlling the heating component and improving the accuracy of the cooking appliance in controlling the temperature of the heating component.

[0030] Optionally, when the cooling fan drives the airflow from the side of the heating element away from the cooling fan to the side of the heating element close to the cooling fan, the temperature detection component detects the inlet air temperature of the second air outlet.

[0031] Optionally, the temperature sensing component is an NTC (Negative Temperature Coefficient) temperature probe.

[0032] When the airflow driven by the cooling fan moves from the side of the heating element close to the cooling fan to the side of the heating element away from the cooling fan, the temperature detection component can detect the temperature of the airflow after passing through the heating element.

[0033] In some technical solutions of this utility model, the cooking appliance also includes a temperature detection component, which is disposed between the first air vent and the heating component.

[0034] In this technical solution, the cooking appliance also includes a temperature detection component, which is positioned between the first air vent and the heating element. The temperature detection component can detect the temperature of the airflow passing through it. By controlling the temperature of the airflow, the opening and closing of the cooling fan can be controlled, thereby controlling the heating element and improving the accuracy of temperature control. Positioning the temperature detection component between the first air vent and the heating element allows it to be closer to the vent, ensuring it is immediately affected by the airflow from the cooling fan, rapidly reducing its surface temperature and increasing the heating duration.

[0035] Optionally, when the cooling fan drives the airflow from the side of the heating element away from the cooling fan to the side of the heating element close to the cooling fan, the temperature detection component can detect the temperature of the airflow after passing through the heating element.

[0036] When the airflow driven by the cooling fan moves from the side of the heating element close to the cooling fan to the side of the heating element far away from the cooling fan, the temperature detection component detects the inlet air temperature of the cooling fan.

[0037] Optionally, the temperature sensing component is an NTC (Negative Temperature Coefficient) temperature probe.

[0038] In some technical solutions of this utility model, the heat dissipation assembly also includes a control component, which is disposed at the first air outlet and is used to control the opening or closing of the first air outlet.

[0039] In this technical solution, the heat dissipation assembly also includes a control component, which is disposed at the first air vent and is used to control the opening or closing of the first air vent. When the control component controls the first air vent to open, the heat dissipation fan can deliver air to the heating component or draw air to the outside of the cooking cavity through the first air vent, thereby achieving heat dissipation for the heating component. When the control component controls the first air vent to close, the control component can reduce the probability that oil fumes or high-temperature gases in the cooking cavity enter the heat dissipation fan or flow to other areas through the heat dissipation fan, thereby reducing the probability that the heat dissipation fan and areas outside the cooking cavity are contaminated by oil fumes or high-temperature gases.

[0040] Optionally, when the cooling fan is working, the control unit controls the opening of the first air vent.

[0041] After the cooling fan stops working, the control unit controls the first air vent to close.

[0042] In some technical solutions of this utility model, the heat dissipation component also includes a rotating shaft connected to a heat dissipation fan; one end of the control component is connected to the rotating shaft, and the other end of the control component is a free end; wherein, when the heat dissipation fan is not working, the control component is in a first position, and the control component blocks the first air vent; when the heat dissipation fan is working, the airflow generated by the heat dissipation fan drives the control component to rotate relative to the first air vent to a second position, and the first air vent opens.

[0043] In this technical solution, the heat dissipation component also includes a rotating shaft connected to the heat dissipation fan; one end of the control component is connected to the rotating shaft, and the other end of the control component is a free end, so that the control component can automatically switch positions according to the working status of the heat dissipation fan, thereby making the control component to control the heat dissipation fan more convenient.

[0044] When the cooling fan is working, the airflow generated by the cooling fan flows to the first air outlet. The control component located at the first air outlet is pushed by the airflow and rotates around the axis of the rotating shaft, thereby driving the control component to rotate relative to the first air outlet to the second position, and the first air outlet opens.

[0045] When the cooling fan is not working, the control component hangs down under the action of gravity, and the control component is in the first position, blocking the first air vent.

[0046] Optionally, the control component is a valve plate, one side of which is connected to a rotating shaft and can rotate relative to the housing of the cooling fan. One side of the valve plate can be fixedly connected to the rotating shaft, and the other side of the valve plate can also be rotatably connected to the rotating shaft.

[0047] The other side of the valve plate is a free end. When the valve plate is not pushed by an external force, it extends along the numerical direction under the action of gravity. The first air vent is located on the side of the cooling fan and also extends in the vertical direction. The valve plate blocks the first air vent.

[0048] In some technical solutions of this utility model, the first air outlet is the air inlet of the cooling fan; or the first air outlet is the air outlet of the cooling fan.

[0049] In this technical solution, the first air vent is the air inlet of the cooling fan. The cooling fan can draw out the airflow around the heating element and discharge it to the outside of the cooking cavity. By drawing out the airflow around the heating element, the cooling fan can not only dissipate heat from the heating element, but also reduce the pressure inside the cooking cavity, thereby increasing the air intake of the fresh air component of the cooking appliance and improving the taste of the food cooked by the cooking appliance.

[0050] The first air outlet is the air outlet of the cooling fan. The cooling fan blows air around the heating element through the first air outlet, which not only dissipates heat from the heating element, but also reduces the probability of oil fumes or high-temperature gases in the cooking cavity entering the cooling fan or flowing to other areas through the cooling fan. This reduces the probability of the cooling fan and areas outside the cooking cavity being contaminated by oil fumes or high-temperature gases.

[0051] In some technical solutions of this utility model, the cooling fan is arranged radially along the fan blades and located on the circumferential outer side of the heating component.

[0052] In this technical solution, the cooling fan is arranged radially along the fan blades and located on the circumferential outer side of the heating component. When the airflow driven by the cooling fan passes through the heating component, the airflow driven by the cooling fan flows radially along the heating component, reducing the probability of the airflow driven by the cooling fan entering the cooking cavity, and further reducing the impact of the cooling fan on the food in the cooking cavity.

[0053] In some technical solutions of this utility model, the heat dissipation component is a spray component, which is arranged facing the heating component and is used to spray liquid onto the heating component.

[0054] In this technical solution, the heat dissipation component is a spray component, positioned towards the heating element. It sprays liquid onto the heating element, where it vaporizes due to the heat. This vaporization absorbs heat, reducing the rate of temperature rise and the overall temperature of the heating element, thus achieving heat dissipation. Furthermore, this liquid-spraying method for heat dissipation does not generate additional high-temperature airflow, further minimizing the impact of heat dissipation on the cooked food. In addition to cooling the heating element, the spray also replenishes the cooking cavity with vaporized water, providing extra moisture to the surface of the food. This forms a water film on the food's surface, slowing down the evaporation of internal moisture and further improving the texture of the cooked food.

[0055] In some technical solutions of this utility model, the spray assembly includes a liquid storage tank, a pump body, and a spray component; the liquid storage tank is used to store liquid; the pump body is disposed in the liquid storage tank; the spray component is connected to the pump body and is disposed towards the heating component; wherein, the pump body is used to drive the liquid in the liquid storage tank to be sprayed onto the heating component through the spray component.

[0056] In this technical solution, the spray assembly includes a liquid storage tank for storing liquid, which facilitates the spray assembly spraying liquid onto the heating element. The spray assembly includes a pump body and a spray component. The pump body is located in the liquid storage tank, and the spray component is connected to the pump body and positioned towards the heating element. The pump body drives the liquid in the liquid storage tank to be sprayed onto the heating element through the spray component, thereby reducing the temperature rise rate and temperature of the heating element and achieving heat dissipation from the heating element.

[0057] Optionally, the storage tank can store clean water.

[0058] Optionally, the spraying component is a nozzle.

[0059] In some technical solutions of this utility model, the cooking appliance also includes a support, which is disposed on the top of the cooking cavity and connected to the main body; a heat dissipation component is disposed on the support.

[0060] In this technical solution, the bracket is connected to the main body, and the heat dissipation component is set on the bracket. The bracket is used to install and support the heat dissipation fan, thereby improving the stability of the heat dissipation component during operation.

[0061] Optionally, the bracket is provided with a column or support for fixing the heat dissipation components.

[0062] The cooking appliance also includes a motor, the output shaft of which is connected to the fan blades. The motor is mounted on a bracket, and the output shaft of the motor drives the fan blades to rotate.

Detailed Implementation

[0074] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0075] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0076] The following reference Figures 1 to 7 This invention describes a cooking appliance according to some embodiments of the present invention.

[0077] In one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a cooking appliance is provided, including a body 100, a heating element 200, a fan blade 300, and a heat dissipation assembly 400; the body 100 is provided with a cooking cavity 110; the heating element 200 is disposed on one side of the cooking cavity 110; the fan blade 300 is disposed on the side of the heating element 200 away from the cooking cavity 110, and is used to drive airflow through the heating element 200 and flow into the cooking cavity 110; the heat dissipation assembly 400 is disposed on the body 100 and is used to dissipate heat from the heating element 200.

[0078] In this embodiment, the cooking appliance includes a body 100, which has a cooking cavity 110 for holding food ingredients, allowing the appliance to cook the ingredients. The cooking appliance also includes a heating element 200, which is disposed on one side of the cooking cavity 110. The heat generated by the heating element 200 is transferred to the food ingredients placed inside the cooking cavity 110 via thermal radiation, thereby cooking the food. The cooking appliance also includes a fan blade 300, which is disposed on the side of the heating element 200 away from the cooking cavity 110. The fan blade 300 drives airflow through the heating element 200, thereby transferring heat to the food ingredients via thermal convection, thus cooking the food.

[0079] The cooking appliance also includes a heat dissipation component 400, which is disposed on the body 100 and is used to dissipate heat from the heating element 200. When cooking food using a cooking appliance with a heat dissipation component 400, the airflow speed inside the cooking chamber 110 can be reduced by decreasing the rotation speed of the fan blades 300. This reduces the proportion of heat generated by the heating element transferred to the food via thermal convection and increases the proportion of heat transferred to the food via thermal radiation. This reduces the rate of moisture evaporation during cooking, especially effectively reducing the rate of moisture evaporation from the food's interior, resulting in food that is crispy on the outside and tender on the inside, reducing the probability of the food being too dry, and improving the taste. At the same time, during the cooking process, the heat dissipation component 400 dissipates heat from the heating element 200. Even if the fan blades 300 rotate at a low speed and the airflow speed inside the cooking chamber 110 is slow, the heat generated by the heating element 200 will be consumed by the heat dissipation component 400, reducing the heating rate and temperature of the heating element 200. This reduces the probability of damage to the heating element 200 due to excessively high or rapid heating, and improves the stability of the heating element 200 during the cooking process.

[0080] Furthermore, the heat dissipation component 400 dissipates heat to the heating component 200, allowing the heat dissipation component 400 to turn on or off according to the temperature of the heating component 200. This enables the heat dissipation component 400 to control the temperature of the heating component 200, improving the temperature stability of the heating component 200 during cooking and further enhancing the taste of the food cooked by the cooking appliance.

[0081] The fan blade 300 is located on the side of the heating element 200 away from the cooking cavity 110, that is, the heating element 200 is located on the side of the fan blade 300 close to the cooking cavity 110. The heating element 200 is as close to the cooking cavity 110 as possible, which shortens the heat radiation distance between the heating element 200 and the food in the cooking cavity 110 and enhances the effect of radiative heat transfer.

[0082] Specifically, the cooking appliance provided in this application heats food by enhancing radiative heat transfer and reducing convective heat transfer, thereby reducing the impact of convective heat transfer on the loss of moisture from the food. Furthermore, it improves the stability of the heating element 200 during operation by using the heat dissipation component 400 to dissipate heat from the heating element 200.

[0083] Specifically, the heating element 200 is a heating tube, a heating plate, or a heating wire.

[0084] Optionally, the heat dissipation component 400 is disposed on the circumferential outer side of the heating component 200.

[0085] The heating element 200 is installed below the fan blade 300.

[0086] Alternatively, the cooking appliance can be an air fryer or a steam oven.

[0087] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0088] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the heat dissipation component 400 is a heat dissipation fan 410. The heat dissipation fan 410 is provided with a first air vent 412. The first air vent 412 faces the heating component 200 and is used to drive the airflow through the heating component 200 to the area outside the cooking cavity 110.

[0089] In this embodiment, the heat dissipation component 400 is a heat dissipation fan 410. The heat dissipation fan 410 is provided with a first air outlet 412 facing the heating component 200, which drives airflow through the heating component 200. After flowing through the heating component 200, the airflow can carry the heat generated by the heating component 200 away from the heating component 200, thereby increasing the heat dissipation rate of the heating component 200 and reducing the temperature rise rate and temperature of the heating component 200, thus achieving heat dissipation of the heating component 200. After passing through the heating component 200, the airflow flows to an area outside the cooking cavity 110, reducing the impact of the hot airflow generated by the heat dissipation fan 410 on the food inside the cooking cavity 110, and further improving the taste of the food cooked in the cooking cavity 110.

[0090] Specifically, the cooling fan 410 can drive airflow to flow radially along the heating element 200, that is, the cooling fan 410 drives airflow to pass through the heating element 200 in a horizontal direction, and the airflow flows from one side of the heating element 200 to the other side of the heating element 200 and is discharged to the outside of the cooking appliance.

[0091] The cooling fan 410 can also drive the airflow to flow away from the cooking cavity 110. That is, the cooling fan 410 drives the airflow from the side of the heating element 200 close to the cooking cavity 110 to the side of the heating element 200 away from the cooking cavity 110. The airflow can flow to the heat dissipation cavity of the cooking appliance and then flow to the outside of the cooking appliance.

[0092] Optionally, the housing and fan blades of the cooling fan 410 may be made of materials with a temperature resistance of 200 degrees Celsius or higher.

[0093] Optionally, the heating element 200 is a heating tube, and the cooling fan 410 is located around the heating element 200. By slowing down the fan blade speed 300, heat transfer via convection can be reduced. However, if the surface temperature of the heating tube becomes too high, there is a risk of the tube bursting, and it will also affect the temperature rise of some electrical components above the heating tube. Therefore, installing the cooling fan 410 near the heating tube can reduce the surface temperature of the heating tube and prevent the temperature of the heating tube and its surrounding area from becoming too high.

[0094] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0095] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the main body 100 is provided with a second air vent 120, which is located on the side of the heating component 200 away from the heat dissipation fan 410. The cooking cavity 110 is connected to the outside of the main body 100 through the second air vent 120.

[0096] In this embodiment, the main body 100 is provided with a second air vent 120, which is located on the side of the heating component 200 away from the heat dissipation fan 410. The cooking cavity 110 communicates with the outside of the main body 100 through the second air vent 120, such as... Figure 1 and Figure 2 As shown, when the cooling fan 410 drives the airflow from the side of the heating element 200 closest to the cooling fan 410 to the side of the heating element 200 furthest from the cooling fan 410 (the airflow along...) Figure 1 and Figure 2 (Flowing in the direction indicated by the middle arrow A), the airflow that moves to the side of the heating element 200 away from the heat dissipation fan 410 will be discharged from the cooking cavity 110 through the second air vent 120, thereby reducing the impact of the hot airflow generated by the heat dissipation fan 410 on the food in the cooking cavity 110.

[0097] The main body 100 is provided with a second air vent 120, which is located on the side of the heating element 200 away from the heat dissipation fan 410. The cooking cavity 110 is connected to the outside of the main body 100 through the second air vent 120, such as... Figure 3 and Figure 4As shown, when the cooling fan 410 drives the airflow from the side of the heating element 200 away from the cooling fan 410 to the side of the heating element 200 close to the cooling fan 410 (the airflow along...) Figure 3 and Figure 4 (Flowing in the direction indicated by arrow B), the external air of the cooking appliance enters the cooking chamber 110 through the second air vent 120, and is then discharged from the cooking chamber 110 by the cooling fan 410, thereby reducing the impact of the hot airflow generated by the cooling fan 410 on the food inside the cooking chamber 110.

[0098] Specifically, the cooling fan 410 is an axial flow fan or a centrifugal fan.

[0099] The cooling fan 410 is an exhaust fan or a blower fan.

[0100] The main body 100 is provided with a third air vent. The first air vent 412 of the cooling fan 410 is connected to the third air vent. The third air vent and the second air vent 120 are located on both sides of the heating element 200 in the radial direction. The cooling fan 410 drives the airflow from the second air vent 120 through the heating element 200 to the third air vent, or the cooling fan 410 drives the airflow from the third air vent through the heating element 200 to the second air vent 120. The third air vent and the second air vent 120 are directly opposite each other, which can quickly exhaust the temperature near the heating element 200 through the second air vent 120, avoiding slow heat dissipation near the heating element 200. In addition, the third air vent is directly opposite the second air vent 120, avoiding the direction directly facing the baking pan, reducing the impact of the heat transfer of the cooling fan 410 on the rapid moisture loss of the food in the baking pan.

[0101] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0102] like Figure 1 and Figure 3 As shown, the cooking appliance also includes a temperature detection component 500, which is disposed between the second air vent 120 and the heating component 200.

[0103] In this embodiment, the cooking appliance also includes a temperature detection component 500, which is disposed between the second air vent 120 and the heating component 200. The temperature detection component 500 can detect the temperature of the airflow flowing through it. The temperature of the airflow flowing through the temperature detection component 500 can be used to control the opening and closing of the cooling fan 410, thereby controlling the heating component 200 and improving the accuracy of the cooking appliance in controlling the temperature of the heating component 200.

[0104] Optionally, when the cooling fan 410 drives the airflow from the side of the heating component 200 away from the cooling fan 410 to the side of the heating component 200 close to the cooling fan 410, the temperature detection component 500 detects the air inlet temperature of the second air outlet 120.

[0105] Optionally, the temperature sensing component 500 is an NTC (Negative Temperature Coefficient) temperature probe.

[0106] When the airflow driven by the cooling fan 410 moves from the side of the heating element 200 close to the cooling fan 410 to the side of the heating element 200 away from the cooling fan 410, the temperature detection element 500 can detect the temperature of the airflow after passing through the heating element 200.

[0107] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0108] like Figure 2 and Figure 4 As shown, the cooking appliance also includes a temperature detection component 500, which is disposed between the first air vent 412 and the heating component 200.

[0109] In this embodiment, the cooking appliance also includes a temperature detection component 500, which is positioned between the first air vent 412 and the heating component 200. The temperature detection component 500 can detect the temperature of the airflow passing through it. By controlling the temperature of the airflow, the opening and closing of the cooling fan 410 can be controlled, thereby controlling the heating component 200 and improving the accuracy of temperature control for the heating component 200. The placement of the temperature detection component 500 between the first air vent 412 and the heating component 200 allows it to be closer to the vent, enabling it to be immediately affected by the airflow from the cooling fan 410, rapidly reducing the surface temperature of the temperature detection component and increasing the heating duration of the heating component 200.

[0110] Optionally, when the cooling fan 410 drives the airflow from the side of the heating element 200 away from the cooling fan 410 to the side of the heating element 200 close to the cooling fan 410, the temperature detection component 500 can detect the temperature of the airflow after passing through the heating element 200.

[0111] When the airflow driven by the cooling fan 410 moves from the side of the heating element 200 close to the cooling fan 410 to the side of the heating element 200 away from the cooling fan 410, the temperature detection element 500 detects the air inlet temperature of the cooling fan 410.

[0112] Optionally, the temperature sensing component 500 is an NTC (Negative Temperature Coefficient) temperature probe.

[0113] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0114] like Figure 5 and Figure 6 As shown, the heat dissipation assembly 400 also includes a control component 610, which is disposed at the first air vent 412 and is used to control the opening or closing of the first air vent 412.

[0115] In this embodiment, the heat dissipation assembly 400 further includes a control component 610, which is disposed at the first air vent 412 and is used to control the opening or closing of the first air vent 412. When the control component 610 controls the first air vent 412 to open, the heat dissipation fan 410 can deliver air to the heating component 200 or draw air to the outside of the cooking cavity 110 through the first air vent 412, thereby achieving heat dissipation for the heating component 200. When the control component 610 controls the first air vent 412 to close, the control component 610 can reduce the probability that oil fumes or high-temperature gases in the cooking cavity 110 enter the heat dissipation fan 410 or flow to other areas through the heat dissipation fan 410, thereby reducing the probability that the heat dissipation fan 410 and areas outside the cooking cavity 110 are contaminated by oil fumes or high-temperature gases.

[0116] Optionally, when the cooling fan 410 is working, the control unit 610 controls the first air vent 412 to open.

[0117] After the cooling fan 410 stops working, the control unit 610 controls the first air vent 412 to close.

[0118] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0119] like Figure 5 and Figure 6 As shown, the heat dissipation assembly 400 also includes a rotating shaft 620, which is connected to the cooling fan 410; one end of the control component 610 is connected to the rotating shaft 620, and the other end of the control component 610 is a free end; wherein, as Figure 5 As shown, when the cooling fan 410 is not working, the control component 610 is in the first position, and the control component 610 blocks the first air vent 412; as Figure 6 As shown, when the cooling fan 410 is working, the airflow generated by the cooling fan 410 drives the control component 610 to rotate relative to the first air outlet 412 to the second position, and the first air outlet 412 is opened.

[0120] In this embodiment, the heat dissipation assembly 400 also includes a rotating shaft 620 connected to the heat dissipation fan 410; one end of the control component 610 is connected to the rotating shaft 620, and the other end of the control component 610 is a free end, so that the control component 610 can automatically switch positions according to the working state of the heat dissipation fan 410, thereby making it more convenient for the control component 610 to control the heat dissipation fan 410.

[0121] When the cooling fan 410 is working, the airflow generated by the cooling fan 410 flows to the first air outlet 412. The control component 610 located at the first air outlet 412 is pushed by the airflow and rotates around the axis of the rotating shaft 620, thereby driving the control component 610 to rotate relative to the first air outlet 412 to the second position, and the first air outlet 412 is opened.

[0122] When the cooling fan 410 is not working, the control component 610 hangs down under the action of gravity, and the control component 610 is in the first position, blocking the first air vent 412.

[0123] Optionally, the control component 610 is a valve plate, one side of which is connected to the rotating shaft 620 and can rotate relative to the housing of the cooling fan 410. One side of the valve plate can be fixedly connected to the rotating shaft 620, and the other side of the valve plate can also be rotatably connected to the rotating shaft 620.

[0124] The other side of the valve plate is a free end. When the valve plate is not pushed by an external force, it extends along the numerical direction under the action of gravity. The first air vent 412 is located on the side of the cooling fan 410 and also extends in the vertical direction. The valve plate blocks the first air vent 412.

[0125] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0126] like Figure 3 and Figure 4 As shown, the first air vent 412 is the air inlet of the cooling fan 410.

[0127] like Figure 1 and Figure 2 As shown, the first air outlet 412 is the air outlet of the cooling fan 410.

[0128] In this embodiment, the first air vent 412 is the air inlet of the cooling fan 410. The cooling fan 410 can draw out the airflow around the heating component 200 and discharge it to the outside of the cooking cavity 110. By drawing out the airflow around the heating component 200 through the cooling fan 410, the pressure inside the cooking cavity 110 can be reduced while the heating component 200 is cooled. This increases the air intake of the fresh air component of the cooking appliance and improves the taste of the food cooked by the cooking appliance.

[0129] The first air vent 412 is the air outlet of the cooling fan 410. The cooling fan 410 blows air around the heating element 200 through the first air vent 412. While achieving heat dissipation for the heating element 200, it reduces the probability that oil fumes or high-temperature gases in the cooking cavity 110 will enter the cooling fan 410 or flow to other areas through the cooling fan 410. This reduces the probability that the cooling fan 410 and areas outside the cooking cavity 110 will be contaminated by oil fumes or high-temperature gases.

[0130] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0131] like Figure 1 and Figure 2 As shown, the cooling fan 410 is along the radial direction of the fan blade 300 ( Figure 1 Arranged in the direction indicated by the middle arrow C, located circumferentially around the heating element 200. Figure 1 (In the direction indicated by the middle arrow D) Outwards.

[0132] In this embodiment, the cooling fan 410 is arranged radially along the fan blade 300 and located on the circumferential outer side of the heating component 200. When the airflow driven by the cooling fan 410 passes through the heating component 200, the airflow driven by the cooling fan 410 flows radially along the heating component 200, reducing the probability of the airflow driven by the cooling fan 410 entering the cooking cavity 110, and further reducing the impact of the cooling fan 410 on the food in the cooking cavity 110.

[0133] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0134] like Figure 7 As shown, the heat dissipation component 400 is a spray component 420, which is disposed toward the heating component 200 and is used to spray liquid onto the heating component 200.

[0135] In this embodiment, the heat dissipation component 400 is a spray component 420, which is positioned towards the heating component 200 and sprays liquid onto the heating component 200. The liquid sprayed onto the heating component 200 vaporizes due to the heat from the heating component 200. The vaporization of the liquid absorbs heat, thereby reducing the temperature rise rate and temperature of the heating component 200, thus achieving heat dissipation from the heating component 200. Furthermore, by spraying liquid onto the heating component 200 to dissipate heat, no additional high-temperature airflow is generated during the heat dissipation process, further reducing the impact of heat dissipation from the heating component 200 on the cooked food. By spraying liquid onto the heating component 200 to dissipate heat, a certain amount of vaporized water vapor can also be added to the cooking cavity 110, thereby additionally replenishing the surface of the food and forming a water film on the surface of the food to slow down the evaporation rate of internal moisture, further improving the taste of the cooked food.

[0136] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0138] In this embodiment, the spray assembly 420 includes a liquid storage tank 422 for storing liquid, thereby facilitating the spray assembly 420 to spray liquid onto the heating element 200. The spray assembly 420 includes a pump body 424 and a spray component 426. The pump body 424 is disposed in the liquid storage tank 422, and the spray component 426 is connected to the pump body 424 and is disposed towards the heating element 200. The pump body 424 is used to drive the liquid in the liquid storage tank 422 to be sprayed onto the heating element 200 through the spray component 426, thereby reducing the temperature rise rate and temperature of the heating element 200 and achieving heat dissipation from the heating element 200.

[0139] Optionally, the liquid storage tank 422 can store clean water.

[0140] Optionally, the spray component 426 is a nozzle.

[0141] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0142] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the cooking appliance also includes a support 700, which is located on the top of the cooking cavity 110 and connected to the main body 100; a heat dissipation component 400 is located on the support 700.

[0143] In this embodiment, the bracket 700 is connected to the body 100, and the heat dissipation component 400 is disposed on the bracket 700. The bracket 700 is used to install and support the heat dissipation component 400, thereby improving the stability of the heat dissipation component 400 during operation.

[0144] Optionally, the bracket 700 is provided with a column or support 700 for fixing the heat dissipation component 400.

[0145] The cooking appliance also includes a motor, the output shaft of which is connected to the fan blade 300. The motor is mounted on the bracket 700, and the output shaft of the motor drives the fan blade 300 to rotate.
