Description

Technical Field

[0001] The invention relates to a cooking device, and in particular to an air guiding and heat dissipating structure of the cooking device and the cooking device. Background Art

[0002] As people's quality of life continues to improve, kitchen appliances are becoming more and more abundant. Microwave ovens, ovens, steamers, etc. have gradually become essential kitchen appliances for family life. In order to effectively utilize kitchen space and reduce purchase costs, people have invented all-in-one steamer, oven, and microwave oven. Since the steamer, oven, and microwave oven all-in-one machine needs to highly integrate the steaming function, baking function, and microwave function, the space design of the machine is very important. Both the steaming function and the grilling function require the use of an air duct structure. The microwave structure contains microwave generating devices such as magnetrons. In previous designs, the air duct structure and the microwave generating device were independent of each other. The existing air guide structure is mainly installed in the upper mounting plate of the machine, which serves to discharge the steam in the inner pot or the hot air during the grilling process, but it has the following disadvantages: a. It occupies the upper space of the machine, and there will be certain conflicts with the waveguide and other structures in the microwave; b. Exhausting hot air directly above will form condensed water on the upper surface of the door body, and water droplets will fall when the user opens the door, resulting in a poor user experience; c. The air guide plate will continue to spray hot air or hot water vapor during the operation of the machine. Since the air guide cover is installed on the top, and the steam-bake micro-in-one machine has a heating pipe on the top, the gas temperature in the air guide cover is relatively high. When the user opens the door after cooking, he will be directly sprayed with hot air, which has certain safety hazards and bad experience; d. The air guide plate installed on the top will condense during the blowing process, so there will definitely be water accumulation. In the long run, the accumulated water cannot be discharged, which will affect the performance of the machine and cause certain health problems. In addition, in the steam-bake micro-in-one machine, multiple heat dissipation systems are often required to deal with the heat dissipation of the microwave system, the heat dissipation of the grilling system and the heat dissipation of the steam system, which affects the overall cost control and space utilization, and increases the power consumption of the machine, which is neither energy-saving nor environmentally friendly. Summary of the invention

[0008] In order to make the spatial layout more reasonable, the waveguide is arranged at the top of the cooking cavity, the magnetron is arranged at the rear of the cooking cavity, the waveguide extends backward from the rear of the cooking cavity and is installed on the magnetron, the cooling fan is arranged directly below the magnetron, and the exhaust fan is arranged at the rear of the cooking cavity and below the cooling fan.

[0009] The exhaust fan may have a variety of installation structures. Preferably, a fan installation box is provided at the rear of the air guide cover, the exhaust fan is installed in the fan installation box, and the fan installation box is provided with an air inlet of the air guide cover.

[0010] In order to allow the steam exhausted from the air guide hood to be exhausted through the front plate of the cavity, an air outlet hole corresponding to the air outlet of the air guide hood is opened on the front plate of the cooking cavity.

[0011] In order to prevent condensed water in the air guide hood from dripping onto the door of the cooking device, a condensed water tank is installed at the front bottom of the cooking cavity, and a guide channel is provided at the front bottom of the air guide hood to guide the condensed water in the air guide hood to the condensed water tank.

[0012] As a preferred embodiment of any of the above schemes, the air outlet of the cooking cavity is connected to the air inlet of the air guide cover through an exhaust pipe.

[0013] The technical solution adopted by the present invention to solve the above-mentioned third technical problem is: a cooking device, which is applied with the above-mentioned air guiding and heat dissipation structure, an upper heating tube is installed on the inner top of the cooking cavity, and a lower heating tube is installed on the bottom of the cooking cavity.

[0014] Further preferably, a hot air component is installed on the back of the cooking cavity, and hot air holes are opened on the back plate of the cooking cavity.

[0015] Further preferably, a water inlet hole is opened on the side wall of the cooking cavity, and a heating plate is installed at the bottom of the cooking cavity, and the upper surface of the heating plate is recessed downward to form a liquid receiving cavity.

In addition, the exhaust fan of the air guiding hood and the heat dissipation device of the magnetron adopt an integrated design, which improves the space utilization of the machine, reduces energy consumption and cost, and is more energy-saving and environmentally friendly.

[0023] The present invention is further described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 6As shown, the air guide and heat dissipation structure of the cooking device of this embodiment includes a cooking cavity 1, a microwave generating assembly 2, an air guide cover 3, an exhaust fan 4 and a heat dissipation fan 5. Among them, the microwave generating assembly 2 includes a magnetron 21 and a waveguide 22, the waveguide 22 is arranged at the top of the cooking cavity 1, the magnetron 21 is arranged at the rear of the cooking cavity 1, the waveguide 22 extends backward from the rear of the cooking cavity 1 and is installed on the magnetron 21, and the microwave generating assembly 2 also includes components such as a high-voltage transformer, a high-voltage capacitor and a high-voltage fuse, which will not be described in detail. In this embodiment, the air guide hood 3 is arranged on the left side of the cooking cavity 1, the air inlet 31 of the air guide hood 3 is fluidly connected with the air outlet 11 of the cooking cavity 1 through the exhaust pipe 7, the air outlet 32 ​​of the air guide hood 3 is arranged in front of the air guide hood 3, and the exhaust fan 4 is arranged in the air duct between the air inlet 31 and the air outlet 32 ​​of the air guide hood 3. Specifically, a fan installation box 33 is arranged at the rear of the air guide hood 3, the exhaust fan 4 is installed in the fan installation box 33, and the air inlet 31 of the air guide hood 3 is opened at the bottom of the fan installation box 33. The heat dissipation fan 5 is located above the exhaust fan 4 and is coaxially arranged with the exhaust fan 4. The heat dissipation fan 5 is located below the magnetron 21 to dissipate heat from the magnetron 21. Therefore, the exhaust of the air guide hood 3 and the heat dissipation of the magnetron 21 adopt an integrated structure, which is more compact, has high space utilization, is conducive to reducing the power consumption and cost of the machine, and is more energy-saving and environmentally friendly.

[0025] like Figure 5 and Figure 6 As shown, the air outlets 32 of the air guide hood 3 are spaced apart from top to bottom in front of the air guide hood 3. Since the front portion of the air guide plate 3 is mounted on the front plate 12 of the cooking cavity 1, air outlet holes 121 corresponding to the air outlets 32 of the air guide hood 3 are provided on the front plate 12, that is, the air outlet holes 121 are in the shape of vertical strips.

[0026] A condensation water tank 6 is installed at the front bottom of the cooking cavity 1. The condensation water tank 6 is in a strip shape and is arranged horizontally along the lower edge of the front plate 12. A guide channel 34 is provided at the front bottom of the air guide cover 3 to guide the condensation water in the air guide cover 3 to the condensation water tank 6. In this way, when the hot air in the air guide cover 3 condenses during the discharge process, it will directly flow into the condensation water tank 6 through the guide channel 34, and no water will accumulate in the air guide cover 3, so that it is more hygienic to use and improve the user experience.

[0027] In addition, the cooking device of this embodiment is provided with an upper heating tube 81 at the inner top of the cooking cavity 1, and a lower heating tube 82 at the bottom of the cooking cavity 1. A hot air assembly 83 is installed at the back of the cooking cavity 1, and hot air holes 131 are opened on the back plate 13 of the cooking cavity 1. The working principles of the upper heating tube 81, the lower heating tube 82 and the hot air assembly 83 are the same as those of the existing ovens, and will not be described in detail here.

[0028] In this embodiment, the steam generating device is in the form of a heating plate 9. Specifically, a water inlet hole 14 is opened on the side wall of the cooking cavity 1, and the heating plate 9 is installed at the bottom center of the cooking cavity 1. The upper surface of the heating plate 9 is recessed downward to form a liquid receiving cavity 91. A water tank (not shown) is provided outside the cooking cavity 1, and water in the water tank flows into the heating plate 9 through the water inlet hole 14, and is heated and evaporated to generate steam.

[0029] The cooking device of this embodiment is a steam-bake micro-integrated machine that integrates steam function, grill function and microwave function. Since the space at the top, bottom and back of the steam-bake micro-integrated machine is very tight, and the space utilization rate on both sides of the cooking cavity 1 is not high, therefore, in this embodiment, the air guide cover 3 is installed on the side of the machine, making full use of the side space of the cooking cavity 1, avoiding the upper heating pipe 81, the lower heating pipe 82, the hot air assembly 83 at the back and the back heating pipe (not shown in the figure). In addition, since the temperature of the side of the cooking cavity 1 is relatively low, the air guide cover 3 is installed on the side of the cooking cavity, and the temperature of the exhaust gas is also low, and the exhaust gas will not directly appear in front of the cook, and closing the door is also safer, which improves the user experience.
