Description

Technical Field

[0001] The utility model relates to the field of kitchen appliances, in particular to a heat dissipation structure of an electric pizza oven and an electric pizza oven using the heat dissipation structure. Background Art

[0002] An electric pizza oven is a common kitchen appliance. It generally includes a shell and a baking cavity. There is an isolation cavity between the shell and the baking cavity, and electronic components are disposed in the isolation cavity. When the electric pizza oven is operating, the heat generated by the baking cavity will be transferred to the electronic components and the shell, thereby increasing the temperature of the electronic components and the shell. Excessive temperature will shorten the life of the electronic components and make them prone to failure. At the same time, an overly hot shell can easily cause burns if the user accidentally touches it. In the prior art, a fan is usually disposed in the isolation cavity, and an air inlet and an air outlet are provided on the shell. When the electric pizza oven is operating, the fan can blow the air in the isolation cavity out from the air outlet to form a negative pressure zone in the isolation cavity. The negative pressure zone can inhale air from the outside of the shell through the air inlet and form cold air. The cold air flows into the isolation cavity to exchange heat with the electronic components and the shell, thereby dissipating heat from the electronic components and the shell at the same time. However, when adopting this heat dissipation structure, the negative pressure area tends to draw in hot air from other positions of the isolation cavity and mix it with the cold air inhaled from the air inlet to form a mixed gas. The temperature of the mixed gas is slightly higher than the temperature of the cold air inhaled from the air inlet. Therefore, the mixed gas has no obvious cooling effect on the electronic components and the shell, resulting in a poor heat dissipation effect, especially making it difficult to meet the heat dissipation requirements of the electronic components. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an electric pizza oven heat dissipation structure that can avoid the influence of the mixed gas formed by the mixing of cold air and hot air on heat dissipation, and can better dissipate heat from electronic components.

[0035] Reference Figure 1 and Figure 2 According to the first embodiment of the present invention, an electric pizza oven heat dissipation structure includes a shell 100, an isolation cover 500, electronic components 300 and a fan 400. A baking cavity 200 is provided inside the shell 100. The baking cavity 200 is generally connected to the shell 100 by bolt connection, clamp connection, riveting connection or other connection methods. In this embodiment, the shell 100 and the baking cavity 200 are rectangular in shape. The baking cavity 200 is usually provided with a tray and a heating component. Food can be placed on the tray. When the heating component is powered on, it will generate heat to heat the food. At the same time, the heat will be conducted to other components of the electric pizza oven. The shell 10 0 and the baking cavity 200. There is a first isolation cavity 110 between the baking cavity 200. The first isolation cavity 110 can slow down the heat transfer from the baking cavity 200 to the shell 100. The isolation cover 500 is located inside the first isolation cavity 110. The isolation cover 500 and the inner wall of the shell 100 are enclosed to form a second isolation cavity 510. The side wall of the shell 100 is provided with an air inlet 120 connecting the second isolation cavity 510 and the outside of the shell 100. The side wall of the isolation cover 500 is provided with an air outlet 520 connecting the first isolation cavity 110 and the second isolation cavity 510. The electronic components 300 are arranged in the second isolation cavity 510, and the fan 400 is arranged in the second isolation cavity 510.

[0036] The heat dissipation structure of the electric pizza oven in the embodiment of the present invention arranges the electronic components 300 and the fan 400 in the second isolation cavity 510. When the fan 400 is powered on, the air outside the shell 100 flows into the second isolation cavity 510 from the air inlet 120 and forms cold air. The cold air dissipates the heat of the electronic components 300, and then the cold air is blown out from the air outlet 520 to the first isolation cavity 110 to dissipate the heat of the shell 100 and the baking cavity 200. As a result, the heat dissipation structure of the electric pizza oven in this embodiment has a better cooling and heat dissipation effect on the electronic components, and solves the technical problem that the fan of the heat dissipation structure of the traditional electric pizza oven will inhale hot air and cold air at the same time when inhaling air, thereby improving the cooling effect of the cold air on the electronic components, the shell and the baking cavity, and making the heat dissipation effect better.

[0037] It should be added that the heat generated by the heating component when it is powered on will also be conducted to the isolation cover 500 , and the cold air in the second isolation cavity 510 and the cold air in the first isolation cavity 110 can both cool the isolation cover 500 .

[0038] It should be noted that the air inlet 120 and the air outlet 520 can be a mesh structure composed of a plurality of spaced-apart through holes, thereby facilitating the flow of air in and out of the second isolation cavity 510 while preventing larger debris from entering the second isolation cavity 510 .

[0039] It should be noted that the shell 100 can be provided with a connecting port connecting the first isolation cavity 110 and the outside of the shell 100, so that the hot air after cooling the shell 100 can be discharged. A connecting port connecting the first isolation cavity 110 and the inside of the baking cavity 200 can also be opened on the baking cavity 200. The air enters the baking cavity 200 from the first isolation cavity 110 and is then discharged to the outside of the shell 100 through the baking cavity 200. At the same time, the air can also absorb part of the heat of the baking cavity 200, thereby cooling the baking cavity 200.

[0040] Reference Figure 2 and Figure 3 In some embodiments of the present invention, the electronic components 300 separate the second isolation cavity 510 into an air inlet channel 530 and an air outlet channel 540. The air inlet channel 530 is connected to the air inlet 230 and the air inlet end of the fan 400, and the air outlet channel 540 is connected to the air outlet 520 and the air outlet end of the fan 400.

[0041] By adopting the above structure, air enters the air inlet duct 530 through the air inlet 120 to cool one side of the electronic component 300, and then the air is sucked into the air inlet end of the fan 400 and blown out from the air outlet end of the fan 400 to the air outlet duct 540 to cool the other side of the electronic component 300. This can increase the contact area between the cold air and the surface of the electronic component 300, making the heat conduction efficiency between the cold air and the electronic component 300 higher, and at the same time can extend the time that the cold air stays inside the isolation cover 500, so as to better cool the electronic component 300.

[0042] Reference Figure 2 and Figure 3 In some embodiments of the present invention, a mounting bracket 600 is provided in the second isolation cavity 510, and the mounting bracket 600 is connected to the isolation cover 500 and / or the side wall of the shell 100. The electronic components 300 are arranged on the side of the mounting bracket 600 away from the inner wall of the shell 100. The mounting bracket 600 is usually made of insulating material.

[0043] By adopting the above structure, the electronic component 300 is arranged on the side of the mounting frame 600 away from the inner wall of the shell 100. The mounting frame 600 can fix the electronic component 300 to the side wall of the shell 100. The mounting frame 600 can support and protect the electronic component 300, so that the electronic component 300 is not easily deformed or broken. In daily use, the mounting frame 600 made of insulating material can insulate and protect the electronic component 300, and when liquid outside the shell splashes into the second isolation cavity 510 from the air inlet 120, the mounting frame 600 can block the liquid to prevent the liquid from splashing and damaging the electronic component 300.

[0044] It is understandable that the mounting bracket 600 can be connected to the isolation cover 500 and / or the side wall of the housing 100 by bolt connection, snap connection, pin connection or other connection methods, which is not specifically limited in the present invention.

[0045] It is understandable that the fan 400 may also be placed on the mounting frame 600 so that the mounting frame 600 can provide support, protection, and insulation for the fan 400 .

[0046] Reference Figure 1 and Figure 2 In some embodiments of the present invention, the air inlet 120 and the air outlet 520 are located at the same end of the second isolation cavity 510 , and the fan 400 is located at the other end of the second isolation cavity 510 .

[0047] By adopting the above structure, the distance that the air enters the second isolation cavity 510 and flows toward the fan 400, as well as the distance that the air is blown out of the second isolation cavity 510 by the fan 400, can be extended, thereby increasing the time that the air flows in the second isolation cavity 510, and making the heat conduction efficiency between the cold air and the electronic components 300 higher, thereby better cooling the electronic components 300.

[0048] Reference Figure 2 、 3 6. In some embodiments of the present invention, a guide structure 121 is provided at the periphery of the air inlet 120. The guide structure 121 is used to guide the air to flow toward the electronic components 300. Specifically, the guide structure 121 can be an air guide plate arranged at an angle, the opening of the air guide plate is facing the electronic components 300, and the outer cross-section of the air guide plate can be semicircular, square or other shapes.

[0049] By adopting the above structure, when air flows into the second isolation cavity 510 through the air inlet 120, the guide structure 121 can guide the air to flow toward the electronic component 300, making it easier for the air to contact the surface of the electronic component 300, thereby enhancing the cooling effect on the electronic component 300. The guide structure 121 can also make the air flow into the second isolation cavity 510 more orderly, thereby speeding up the speed at which the air flows into the second isolation cavity 510.

[0050] It is understandable that the air guide can be provided on the periphery of the air inlet 120 by welding, snap-on connection or the like, or can be integrally stamped from the side wall of the shell 100 , and the present invention does not impose any specific limitation on this.

[0051] Reference Figure 1 and Figure 2 In some embodiments of the present invention, the air outlet 520 is stamped and formed on one side surface of the isolation cover 500.

[0052] By adopting the above structure, the air outlet 520 is formed by stamping from one side surface of the isolation cover 500, thereby improving the production efficiency and reducing the production cost.

[0053] Reference Figure 1 and Figure 4 In some embodiments of the present invention, a door assembly 700 is provided on the outside of the shell 100, and a baking cavity opening for storing and taking out food is opened on the side wall between the baking cavity 200 and the door assembly 700. The door assembly 700 is used to open and close the baking cavity opening, and a first ventilation port 130 is opened at a position corresponding to the shell 100 and the door assembly 700.

[0054] By adopting the above structure, the air in the first isolation cavity 110 can cool the door body assembly 700 through the first ventilation port 130, thereby reducing the temperature of the door body assembly 700. At the same time, the air in the first isolation cavity 110 can be discharged to the outside of the shell 100 through the door body assembly 700.

[0055] It is understandable that the efficiency of air flowing out of the first isolation cavity 110 to the door assembly 700 can be improved by providing a plurality of first vents 130 and / or increasing the size of the first vents 130 .

[0056] Reference Figure 1 、 2 6. In some embodiments of the present invention, the baking cavity 200 has a baking cavity shell 210, and a third isolation cavity 140 is arranged between the outer bottom wall of the baking cavity 200 and the inner bottom wall of the shell 100. Support side panels 220 extending to the inner bottom wall of the shell 100 are arranged on opposite sides of the baking cavity shell 210, and the two supported side panels 220 are provided with a second ventilation port 211 connecting the third isolation cavity 140 and the first isolation cavity 110.

[0057] By adopting the above structure, the air in the first isolation cavity 110 can enter the third isolation cavity 140 through the second ventilation port 211 to cool the bottom of the baking cavity 200 and the bottom of the shell 100, thereby reducing the temperature of the bottom of the baking cavity 200 and the bottom of the shell 100.

[0058] It is understandable that the efficiency of air flowing into the third isolation cavity 140 can be improved by providing a plurality of second ventilation openings 211 and / or increasing the size of the second ventilation openings 211 .

[0059] Reference Figure 6 In some embodiments of the present invention, a third vent 150 is opened on the bottom wall of the shell 100 to connect the third isolation cavity 140 and the outside of the shell 100.

[0060] By adopting the above structure, the air in the third isolation chamber 140 can be discharged to the outside of the housing 100 through the third vent 150 .

[0061] It should be noted that the third vent 150 may be a mesh structure composed of a plurality of spaced-apart through holes, thereby facilitating air flow out of the third isolation cavity 140 while preventing larger debris from entering the third isolation cavity 140 .

[0062] Reference Figures 1 to 6 According to the second aspect of the present invention, an electric pizza oven includes an electric pizza oven body, and the electric pizza oven body is configured with the electric pizza oven heat dissipation structure as in the above embodiment.

[0063] The electric pizza oven of the present invention adopts the heat dissipation structure of any of the above-mentioned embodiments, and by arranging the electronic components 300 and the fan 400 in the second isolation chamber 510, when the fan 400 is powered on, it can draw air outside the housing through the air inlet 120 into the second isolation chamber 510 to form cold air. The cold air can exchange heat with the electronic components 300, which have a higher temperature, and remove some of the heat from the electronic components 300. The cold air is then blown out of the air outlet 520 by the fan 400 into the first isolation chamber 110, where it exchanges heat with the housing 100 and removes some of the heat from the housing 100. In this way, the cold air with the lowest temperature just after entering the second isolation chamber 510 can first cool the electronic components 300, and then the cold air with a slightly higher temperature can cool the housing 100.

[0064] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. In addition, the embodiments of the present invention and the features of the embodiments can be combined with each other unless there is a conflict.
