[0048] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0049] Cooking equipment is used to cook food. During the cooking process, a large amount of heat is generated inside the cooking cavity, causing the cavity temperature to rise. This heat is transferred to the electronic components of the equipment, forcing them to operate under high-temperature conditions, which affects their normal operation and lifespan. Simultaneously, the pressure inside the cooking cavity increases. Excessive pressure can cause the door to open, affecting normal operation. Furthermore, the expansion of air inside the cooking cavity and the generation of steam during food heating produce water vapor. This steam condenses upon cooling, and the condensate can also affect the normal operation of the electronic components. Therefore, it is necessary to depressurize the cooking cavity and manage the condensate. Thus, a heat dissipation and pressure relief device is proposed to dissipate heat, relieve pressure, and manage condensate in the cooking equipment.

[0050] For heat dissipation, cooking equipment typically has a mounting plate above the cooking cavity, on which electronic components are mounted. When the cooking equipment is working, the cooking cavity generates a lot of heat, causing the electronic components above the cooking cavity to get heated. Therefore, it is necessary to dissipate heat from the location where the electronic components are mounted above the cooking cavity to ensure the normal operation of the electronic components.

[0051] For pressure relief and condensate treatment, when the cooking equipment is working, the air in the cooking cavity expands due to heat and produces water vapor. Therefore, it is necessary to relieve the pressure in the cooking cavity to prevent excessive pressure from opening the door and to treat the water vapor.

[0052] In some embodiments, the cooking device is a microwave oven; of course, the cooking device may also be a microwave oven, oven, cookware, etc.

[0053] exist Figures 1-5In the example, the heat dissipation and pressure relief device of the microwave oven is described. The heat dissipation and pressure relief device of the microwave oven includes heat dissipation air duct 1, fan 4, condensation air duct 2 and pressure relief air duct 3.

[0054] The heat dissipation duct 1 has a heat dissipation air inlet 11 and a heat dissipation air outlet 12.

[0055] Fan 4 is configured to generate airflow through cooling duct 1.

[0056] The condenser duct 2 has an air outlet, a condensate collection part 21 at the bottom of the condenser duct 2, and a condensation part 22 inside the condenser duct 2.

[0057] The pressure relief air duct 3 passes through the heat dissipation air duct 1, and the pressure relief air duct 3 is configured to connect the cooking cavity of the cooking equipment and the condensation air duct 2.

[0058] Therefore, the heat dissipation and pressure relief device can dissipate heat through the heat dissipation duct 1, and conduct the steam and expanding air generated by heating in the cooking cavity to the condensing duct 2 through the pressure relief duct 3. The steam is condensed by the condensing part 22 of the condensing duct 2 and then retained in the condensate receiving part 21. Because the condensing duct 2 is set up separately, the condensation effect is improved. At the same time, the condensate is retained in the condensing duct 2 and will not flow back into the cooking cavity, avoiding the generation of too much condensate in the cooking cavity. The condensed air is discharged from the air outlet of the condensing duct 2, which will not damage the electronic components.

[0059] The heat dissipation duct 1 is used to dissipate heat from the mounting plate 5, where the electronic components inside the cooking equipment are located, so as to ensure that the operating temperature of the electronic components of the cooking equipment meets the requirements.

[0060] The condenser duct 2 is used to condense and collect the water vapor discharged from the cooking cavity, preventing the condensate from flowing back into the cooking cavity and preventing the water vapor from damaging electronic components.

[0061] The pressure relief duct 3 is used to guide the expanding air and water vapor in the cooking cavity into the condensation duct 2 to reduce the pressure in the cooking cavity and prevent the door from being forced open due to excessive pressure in the cooking cavity.

[0062] In some embodiments, a mounting plate 5 is provided above the cooking cavity. The mounting plate 5 is used to mount electronic components, and the heat dissipation duct 1 dissipates heat from the mounting plate 5 to prevent the electronic components on the mounting plate 5 from operating under high temperature conditions.

[0063] exist Figures 4-5 In one example, the heat dissipation and pressure relief device includes a main air duct component 6 and an air duct cover plate 64.

[0064] The main component 6 of the air duct includes a top wall 61 forming the heat dissipation air duct 1 and a lower side wall 62 located below the top wall 61. The lower side wall 62 is installed on the mounting plate 5. The space enclosed between the mounting plate 5, the top wall 61 and the lower side wall 62 is the heat dissipation air duct 1.

[0065] The main body of the air duct 6 also includes an upper side wall 63 located above the top wall 61, and an air duct cover 64 is installed on the upper side wall 63. The space enclosed by the air duct cover 64, the upper side wall 63, and the top wall 61 is the condensation air duct 2.

[0066] The condensate receiving part 21 at the bottom of the condensate duct 2, which is also the upper wall surface of the top wall 61, facilitates the collection of condensate.

[0067] In some embodiments, the air duct body 6 is integrally formed.

[0068] In some embodiments, the duct cover 64 is a condenser section 22.

[0069] In some embodiments, the upper sidewall 63 is a condensation section 22.

[0070] In some embodiments, the duct cover 64 and the upper sidewall 63 are condensation sections 22.

[0071] The air vent of condenser duct 2 is used to exhaust air from condenser duct 2 to ensure the pressure inside the cooking cavity.

[0072] The air outlets of the condenser duct 2 include a condenser air inlet 23 and a condenser air outlet 24. Outside air enters the condenser duct 2 through the condenser air inlet 23 and exits the condenser duct 2 through the condenser air outlet 24.

[0073] The fan 4 is configured to generate airflow through the condenser duct 2, which can cool the condenser section 22 and improve the condensation effect of the condenser section 22.

[0074] The condenser duct 2 and the heat dissipation duct 1 share the same fan 4, which can save costs and reduce installation space.

[0075] In some embodiments, the fan 4 is a cross-flow fan or a centrifugal fan.

[0076] In some embodiments, the heat dissipation and pressure relief device includes a second fan configured to generate airflow through the condensation duct 2.

[0077] In some embodiments, the first fan and the second fan are cross-flow fans and / or centrifugal fans and / or axial fans.

[0078] The airflow of the condensation duct 2 and the heat dissipation duct 1 is controlled by the second fan and the fan 4, respectively.

[0079] To improve the condensation effect, the pressure relief duct 3 is close to the condenser air inlet 23 and far away from the condenser air outlet 24. The air discharged from the cooking cavity to the condenser air duct 2 through the pressure relief duct 3 needs to travel a long distance to reach the condenser air outlet 24 in order to improve the condensation effect.

[0080] The extension direction of the condensation air duct 2 is the same as or approximately the same as the extension direction of the heat dissipation air duct 1.

[0081] The condensing air duct 2 and the heat dissipation air duct 1 have a certain length and width, and the extension direction of the condensing air duct 2 and the heat dissipation air duct 1 is the length direction of the two.

[0082] The condenser air inlet 23 and the condenser air outlet 24 are located at both ends of the extension direction of the condenser air duct 2, that is, the condenser air inlet 23 and the condenser air outlet 24 are located at both ends of the length direction of the condenser air duct 2.

[0083] The heat dissipation air inlet 11 and the heat dissipation air outlet 12 are located at both ends of the extension direction of the heat dissipation air duct 1, that is, the heat dissipation air inlet 11 and the heat dissipation air outlet 12 are located at both ends of the length direction of the heat dissipation air duct 1.

[0084] In the extending direction, the length of the condensing air duct 2 is close to the length of the heat dissipation air duct 1, so as to increase the length of the condensing section 22 and thus improve the condensing effect.

[0085] In some embodiments, the heat dissipation duct 1 and the condensation duct 2 are arranged in a horizontal or near-horizontal direction, with the condensation duct 2 located above the heat dissipation duct 1. The pressure relief duct 3 is arranged in a vertical or near-vertical direction.

[0086] The pressure relief duct 3 is close to the heat dissipation outlet 12. The temperature at the heat dissipation outlet 12 is higher than the temperature at the heat dissipation inlet 11. Therefore, the pressure relief duct 3 is located at a relatively high temperature. No or almost no condensation will be generated at the pressure relief duct 3, thereby preventing the condensation generated at the pressure relief duct 3 from flowing back into the cooking cavity and reducing the amount of condensation inside the cooking cavity.

[0087] In order to use a single fan 4 to generate airflow through both the heat dissipation duct 1 and the condensation duct 2, the heat dissipation outlet 12 and the condensation inlet 23 are located at one end of the extension direction, and the heat dissipation inlet 11 and the condensation outlet 24 are located at the other end of the extension direction. The direction of airflow through the heat dissipation duct is opposite or approximately opposite to the direction of airflow through the condensation duct.

[0088] The fan 4 is located near the heat dissipation air inlet 11 and the condenser air outlet 24. The air outlet of the fan 4 is opposite to or connected to the heat dissipation air inlet 11; the condenser air outlet 24 is opposite to or connected to the air inlet of the fan 4. Therefore, when the fan 4 is running, it generates airflow from the heat dissipation air inlet 11 to the heat dissipation air outlet 12, and at the same time generates airflow from the condenser air inlet 23 to the condenser air outlet 24.

[0089] Because the pressure relief duct 3 is close to the heat dissipation outlet 12, which is also close to the condenser inlet 23, the airflow from the heat dissipation duct 1 will not create a low-temperature condensation environment in the pressure relief duct 3, thereby reducing condensation within the pressure relief duct 3 and preventing condensate from flowing back into the cooking cavity. Meanwhile, the temperature at the condenser inlet 23 is lower, which is conducive to the condensation of water vapor in the condenser duct 2, improving the condensation effect of the condenser duct 2.

[0090] In some embodiments, the condenser air inlet 23 is located on the duct cover 64, or the condenser air inlet 23 is a narrow notch at its end. The condenser air outlet 24 is a notch located on the upper sidewall 63.

[0091] The heat dissipation air inlet 11 and the heat dissipation air outlet 12 are notches located on the lower side wall 62.

[0092] To further prevent condensation from forming in the pressure relief duct 3, an isolation channel 13 is provided inside the heat dissipation duct 1. The pressure relief duct 3 is located inside the isolation channel 13, which isolates the pressure relief duct 3 from the heat dissipation duct 1 to prevent the airflow from the heat dissipation duct 1 from causing condensation in the pressure relief duct 3.

[0093] The top of the pressure relief duct 3 protrudes from the bottom wall of the condensation duct 2, which is at least outside the pressure relief duct. The bottom wall of the condensation duct 2 is also the upper surface of the top wall 61.

[0094] The condensate evaporates inside the condensate duct 2.

[0095] In some embodiments, the pressure relief duct 3 is in an open state to ensure the pressure relief effect.

[0096] In some embodiments, in order to improve the pressure relief effect and prevent dirt from entering the heat dissipation and pressure relief device, the pressure relief duct 3 includes a switch device 31, which is configured to open the pressure relief duct 3 when the cooking device is working and close the pressure relief duct 3 when the cooking device stops working or after it has stopped working for a period of time.

[0097] In some embodiments, the switching device 31 is a wax motor.

[0098] When the heat dissipation and pressure relief device is running, the fan 4 operates, generating airflow through the heat dissipation duct 1 and the condensation duct 2. The air passes through the heat dissipation duct 1 to carry away heat, thus achieving heat dissipation. The expanding air and water vapor generated in the cooking cavity enter the condensation duct 2 through the pressure relief duct 3. The condensation section 22 of the condensation duct 2 condenses the water vapor in the condensation duct 2 and collects it in the condensate receiving section 21. Excess air is discharged from the condensation outlet 24. Outside air enters the condensation duct 2 through the condensation inlet 23, carrying away the heat from the condensation section 22 and being discharged from the condensation outlet 24, thereby improving the condensation effect of the condensation section 22.

[0099] A cooking device includes a cooking cavity, and an mounting plate 5 is provided above the cooking cavity. The mounting plate 5 is equipped with the aforementioned heat dissipation and pressure relief device. The heat dissipation and pressure relief device includes a duct body 6 and a duct cover 64. One side of the duct body 6 forms a heat dissipation duct 1, and the other side of the duct body 6 and the duct cover 64 form a condensation duct 2.

[0100] When the cooking equipment is working, the cooking chamber is heated, the heat dissipation and pressure relief device operates, and the fan 4 runs, generating airflow through the heat dissipation duct 1 and the condensation duct 2. The air passes through the heat dissipation duct 1 to carry away the heat from the mounting plate 5, achieving heat dissipation and preventing the electronic components on the mounting plate from operating at high temperatures, ensuring that the operating temperature of the electronic components meets the requirements. The expanding air and water vapor generated in the cooking chamber enter the condensation duct 2 through the pressure relief duct 3. The condensation section 22 of the condensation duct 2 condenses the water vapor in the condensation duct 2 and collects it in the condensate receiving section 21. Excess air is discharged from the condensation outlet 24. Outside air enters the condensation duct 2 from the condensation inlet 23, carrying away the heat from the condensation section 22 and being discharged from the condensation outlet 24, thereby improving the condensation effect of the condensation section 22.

[0101] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
