[0029] See also Figure 1 , Figure 1 FIG. 1 is a schematic diagram showing the structure of a cooking device 100 in an embodiment of the present application. The cooking device 100 provided in an embodiment of the present application may be a steamer, a steam oven, or any other cooking device 100 in the prior art. Figure 1 As shown, the cooking device 100 provided in the present application includes an inner pot 110 and a temperature control device 120. The inner pot 110 is provided with a cooking cavity 111, and the cooking cavity 111 is used to hold and cook food. When the cooking device 100 cooks food, the temperature in the cooking cavity 111 is usually higher than the room temperature. Figure 1 As shown, an opening is provided at the front end of the cooking cavity 111. Generally, the cooking device 100 further includes a door body covering the inner pot 110, so as to close the opening through the door body.
[0030] The temperature control device 120 is used to exchange airflow with the cooking cavity 111 to reduce or maintain the temperature in the cooking cavity 111. Figure 2 and Figure 3 As shown, the temperature control device 120 includes a housing 121 with a temperature control cavity 122 therein, the housing 121 includes a baffle 1211 disposed toward the cooking cavity 111 and a back plate 1212 disposed opposite to the baffle 1211, and a gap is formed between the baffle 1211 and the back plate 1212 to form the temperature control cavity 122, as shown in FIG. Figure 3 As shown, the edge of the baffle 1211 is bent toward the back plate 1212 so that the temperature control cavity 122 is formed between the other area of the baffle 1211 and the back plate 1212. The baffle 1211 is provided with air vents 12111 to connect the cooking cavity 111 and the temperature control cavity 122 located on both sides of the baffle 1211, so as to realize the air flow exchange between the temperature control cavity 122 and the cooking cavity 111. A refrigeration cavity 123 for filling refrigerant is provided inside the back plate 1212. The temperature of the refrigeration cavity 123 filled with refrigerant is lower than that of the temperature control cavity 122 and the cooking cavity 111, so that the heat of the temperature control cavity 122 is absorbed by the refrigeration cavity 123 and the temperature of the temperature control cavity 122 is reduced. The temperature control cavity 122 and the cooking cavity 111 are continuously exchanged with air under the action of the air vents 12111, so as to reduce the temperature of the cooking cavity 111 by reducing the temperature of the temperature control cavity 122. The refrigerant can be any refrigerant used in an evaporator in the prior art.
[0031] In one embodiment, the temperature control device 120 further includes a heating element 127 located inside the temperature control chamber 122. Figure 3 As shown, the heating element 127 is disposed on the periphery of the blade 1242 to heat the airflow around the blade 1242, so that the blade 1242 can blow the airflow heated by the heating element 127 into the cooking cavity 111, so as to realize the flow of gas in the cooking cavity 111 while maintaining the temperature in the cooking cavity 111. Preferably, the heating element 127 and the cooling cavity 123 located in the back plate 1212 are used selectively. When the temperature of the cooking cavity 111 needs to be maintained, only the heating element 127 works, and when the cooking cavity 111 needs to be cooled, the heating element 127 stops working.
[0032] In the above solution, by opening the refrigeration cavity 123 on the back plate 1212, the back plate 1212 with a refrigeration effect functions as an evaporator, which is integrated into the back plate 1212 and does not occupy the space of the cooking cavity 111, so that the cooking cavity 111 of the cooking device 100 has a high space occupancy rate and the structure of the cooking device 100 is more compact. At the same time, the baffle 1211 and the temperature control cavity 122 are separated between the back plate 1212 and the cooking cavity 111, and the food grease or food residue in the cooking cavity 111 is difficult to adhere to, and even if a small amount of oil is attached after long-term use, the back plate 1212 has a plate-like structure, which is easy to wipe and clean.
[0033] like Figure 2 and Figure 3 As shown, in one embodiment, the temperature control device 120 further includes a fan 124 that can rotate relative to the housing 121, and the fan 124 includes a rotating shaft 1241 and a blade 1242 connected to the rotating shaft 1241, the rotating shaft 1241 is rotatably connected to the back plate 1212, and the blade 1242 rotates synchronously with the rotating shaft 1241, and the blade 1242 is located inside the temperature control cavity 122 to blow the airflow in the temperature control cavity 122 to the inside of the cooking cavity 111. It can be understood that in order to facilitate the exchange of airflow in the temperature control cavity 122 and the cooking cavity 111, the air outlet 12111 on the baffle 1211 includes an air outlet 12111 located at the edge of the baffle 1211 and a return air outlet 12111 located in the negative pressure area of the fan 124. Figure 3 As shown, the refrigeration cavity 123 is located on the back side of the blade 1242, so that the airflow behind the blade 1242 is first cooled by the refrigeration cavity 123, and at the same time, the fan 124 can blow the airflow in the temperature control cavity 122 that is first cooled by the refrigeration cavity 123 to the inside of the cooking cavity 111, so as to improve the efficiency of the refrigeration cavity 123 in cooling the cooking cavity 111. When the refrigerant flows in the refrigeration cavity 123, the fan 124 works, and the blade 1242 rotates in the temperature control cavity 122. The rotation of the blade 1242 allows the air in the temperature control cavity 122 and the cooking cavity 111 to fully flow and fully contact with the back plate 1212 provided with the refrigeration cavity 123, so as to achieve the purpose of evenly cooling the airflow in the temperature control cavity 122 and the cooking cavity 111.
[0034] like Figure 3 and Figure 4 As shown, in one embodiment, the back plate 1212 is provided with an inlet 125 and an outlet 126 both connected to the refrigeration cavity 123, and the inlet 125 and the outlet 126 are arranged at intervals, so that the refrigerant enters from the inlet 125, flows in the refrigeration cavity 123, and then flows out through the outlet 126. Figure 2 and Figure 3 As shown, in this embodiment, the inlet 125 and the outlet 126 are respectively connected to the condenser 128 and the compressor 129 through pipelines (not shown) to form a refrigeration circuit composed of the condenser 128, the compressor 129 and the refrigeration chamber 123.
[0035] like Figure 4 As shown, in one embodiment, the refrigeration cavity 123 includes at least one curved connecting section 1231 and a first cavity section 1232 and a second cavity section 1233 respectively connected to both ends of the curved connecting section 1231. In this embodiment, as shown in FIG. Figure 4As shown, the refrigeration cavity 123 is a U-shaped structure. In other embodiments, the refrigeration cavity 123 may also be a serpentine structure, etc. In this case, the refrigeration cavity 123 includes a plurality of curved connecting segments 1231, and both ends of each curved connecting segment 1231 are provided with a first cavity segment 1232 and a second cavity segment 1233. In this case, the upper second cavity segment 1233 is connected to the lower first cavity segment 1232 at the first position to form a continuously curved loop.
[0036] like Figure 4 As shown, in one embodiment, the first cavity segment 1232 and the second cavity segment 1233 are arranged in parallel, and the first cavity segment 1232 and the second cavity segment 1233 are located on the same side of the bend connecting segment 1231. In this embodiment, the bend connecting segment 1231 is a straight segment. In other embodiments, the bend connecting segment 1231 may also be a serpentine or other shaped bending structure.
[0037] like Figure 4 As shown, in one embodiment, the inlet 125 is connected to one end of the first cavity section 1232 away from the second cavity section 1233, and the outlet 126 is connected to one end of the second cavity section 1233 away from the bend connecting section 1231, so that after the refrigerant flows into the first cavity section 1232 from the inlet 125, it first flows through the first cavity section 1232, then passes through the bend connecting section 1231 to enter the second cavity section 1233, and flows through the second cavity section 1233 and is discharged from the outlet 126, so that the refrigerant flows completely in the refrigeration cavity 123.
[0038] like Figure 4 As shown in one embodiment, in the height direction, the height of the inlet 125 is lower than the height of the outlet 126, so that the refrigerant flows from bottom to top, reducing the flow rate of the refrigerant, making the refrigerant flow more fully in the cooking cavity 111, and forming a Figure 3 The refrigerant flow direction shown makes the refrigerant flow direction fixed and orderly, and the heat absorption effect is better.
[0039] like Figure 3 and Figure 4 As shown, in one embodiment, the back plate 1212 includes a main board 12121 and a pressure plate 12122 connected to each other, the edge of the pressure plate 12122 is sealed and connected to the end surface of the main board 12121 away from the baffle 1211, and there is a gap between the other parts of the pressure plate 12122 and the main board 12121 to form a refrigeration cavity 123. In some embodiments, the edge of the pressure plate 12122 can be connected to the main board 12121 by welding, rolling, etc. The refrigeration cavity 123 can be formed by adding a pressure plate 12122 to the existing main board 12121. Compared with the cooking device 100 without refrigeration effect in the prior art, it is easy to modify, and the parts are common with the cooking device 100 before improvement, which is convenient for promoting mass production and reducing production costs.
[0040] It can be understood that the larger the area of the back plate 1212 covered by the refrigeration cavity 123 is, the better the cooling effect of the refrigeration cavity 123 on the temperature control cavity 122 and the cooking cavity 111 is. Figure 4 As shown, in one embodiment, the area of the back plate 1212 covered by the refrigeration cavity 123 is not less than 50% of the area of the back plate 1212 to avoid poor refrigeration effect caused by the refrigeration cavity 123 covering too small an area of the back plate 1212 .
[0041] In one embodiment, the thickness of the refrigeration cavity 123 is not greater than 5 mm. If the thickness of the refrigeration cavity 123 is too large on one side, refrigerant reflux may occur. Preferably, in this embodiment, the thickness of the refrigeration cavity 123 is 2 mm, so that the amount of refrigerant stored in the refrigeration cavity 123 is small. Under the premise that the working efficiency of the compressor 129 and the condenser 128 remains unchanged, the refrigerant flow rate in the refrigeration cavity 123 is high, thereby improving the refrigeration effect.
[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0043] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
