Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and in particular to a cooking appliance. Background Art

[0002] To make a thick, white, mellow and delicious soup, it is necessary to promote the mutual dissolution of fat, protein and water. Tumbling is the driving force for cooking soup. When the soup is tumbling, fat, protein and water can only accommodate each other after violent collision. Long-term slow cooking over low heat or short-term high-heat cooking will make the soup tumble continuously after boiling, thereby promoting the mutual dissolution of fat, protein and water to make delicious soup. The electric stew pots used by consumers now usually use long-term slow cooking over low heat or short-term high-heat cooking to make delicious soup. However, long-term slow cooking over low heat or short-term high-heat cooking will cause a large amount of water to evaporate, and there will be little soup left after the soup is cooked.

[0041] See also Figures 1 to 3The present application provides a cooking utensil, comprising a pot body 200 and a pot cover 100 for covering the pot mouth of the pot body 200. The pot cover 100 comprises: a pot cover body 10, a fan 20, a refrigeration component 30, a cold storage component 40 and a heat dissipation component 50. The pot cover body 10 is provided with a refrigeration part 111 and an air duct 101, and the refrigeration part 111 is at least partially provided on the bottom wall of the pot cover body 10. It is worth mentioning that the "bottom wall of the pot cover body 10" refers to the bottom wall of the pot cover body 10 when in use, that is, the side wall of the pot cover body 10 facing the pot body 200. The air duct 101 is arranged in the pot cover body 10, and the air duct 101 has an air inlet 102 and an air outlet 103 opened in the pot cover body 10. The fan 20 is arranged in the air duct 101, and the fan 20 is used to make the air in the air duct 101 flow from the air inlet 102 to the air outlet 103. The refrigeration component 30 has a cold end and a hot end. The cold storage component 40 is arranged at the cold end of the refrigeration component 30, and the heat dissipation component 50 is arranged at the hot end of the refrigeration component 30. From the air inlet 102 to the air outlet 103, the air duct 101 passes through the cold storage component 40, the refrigeration part 111 and the heat dissipation component 50 in sequence. In the cooking appliance provided by the present application, under the action of the fan 20, the outside air enters the air duct 101 through the air inlet 102. In the process of the air flowing from the air inlet 102 to the air outlet 103, the air first passes through the cold storage part 40. Since the cold storage part 40 is arranged at the cold end of the refrigeration part 30, the cold storage part 40 can store cold energy. Therefore, the air becomes cold after passing through the cold storage part 40. When the cooled air passes through the refrigeration part 111, it takes away the heat of the refrigeration part 111, so that the refrigeration part 111 becomes cold. Since the refrigeration part 111 is at least partially arranged on the bottom wall of the pot cover body 10, that is, on the side facing the pot body 200, during use, the steam generated in the pot body 200 will condense into liquid water when it contacts the refrigeration part 111, and fall back into the pot body 200, thereby greatly reducing the evaporation loss of water. In addition, the air duct 101 also passes through the heat sink 50 , so the air cooled by the cold storage element 40 can promptly take away the heat emitted by the refrigeration element 30 , thereby ensuring the refrigeration effect of the refrigeration element 30 .

[0042] For further information, see Figure 1 and Figure 4 The cold storage part 40 is at least partially placed in the air duct 101, and the cold storage part 40 is provided with a refrigeration through hole 41, which keeps the air ducts 101 on both sides of the cold storage part 40 connected. In this way, when the air passes through the cold storage part 40, the cold storage part 40 has a larger contact area with the air, which is conducive to improving the cooling effect on the air.

[0043] For further information, see Figure 1The fan 20 is located on the side of the cold storage part 40 away from the air inlet 102, and the fan 20 is an axial flow fan. In this way, the fan 20 is conducive to doing work and accelerating the cold air after cooling through the refrigeration through hole 41 to generate a certain wind pressure, thereby smoothly pressing the cold air into the corresponding air duct 101, so that the refrigeration part 111 becomes cold and the heat of the heat sink 50 is taken away. In addition, the fan 20 occupies a small space, which is conducive to the miniaturization design of the pot cover 100. For further information, please refer to Figure 1 and Figure 3 A filter screen 1021 is provided at the air inlet 102 to prevent foreign matter from entering the air duct 101 and even blocking the refrigeration through hole 41, thereby ensuring the safety of the pot cover 100.

[0044] See also Figure 1 and Figure 4 Furthermore, a first flexible heat conductive sheet 61 is provided between the refrigeration element 30 and the cold storage element 40, so that the refrigeration element 30 and the cold storage element 40 can be closely fitted, which is beneficial for the refrigeration element 30 to transfer cold to the cold storage element 40. In this embodiment, the first flexible heat conductive sheet 61 is a heat conductive silicone sheet.

[0045] A second flexible heat conductive sheet 62 is provided between the refrigeration element 30 and the heat dissipation element 50, so that the refrigeration element 30 and the heat dissipation element 50 can be closely attached to each other, which is beneficial for the heat dissipation element 50 to the refrigeration element 30, thereby ensuring the normal operation of the refrigeration element 30. In this embodiment, the second flexible heat conductive sheet 62 is a heat conductive silicone sheet.

[0046] In the present embodiment, the cold storage part 40 is a cylinder, the refrigeration part 30 is a square refrigeration sheet, the heat sink 50 is an annular cylinder, the heat sink 50 is arranged around the outside of the cold storage part 40, and the refrigeration part 30 is arranged between the cold storage part 40 and the heat sink 50. In this way, the cold end of the refrigeration part 30 refrigerates the cold storage part 40 to cool it, and the hot end of the refrigeration part 30 dissipates heat through the heat sink 50, thereby ensuring the normal operation of the refrigeration part 30. Further, the outer wall of the cold storage part 40 and the inner wall of the heat sink 50 are both provided with a square groove, and the refrigeration part 30 is installed in the square groove. In this way, the contact area between the refrigeration part 30 and the cold storage part 40 and the heat sink 50 can be increased, which is conducive to the heat transfer between the cold end of the refrigeration part 30 and the cold storage part 40, and the heat transfer between the hot end of the refrigeration part 30 and the heat sink 50. The shape of the cold storage part 40 is not limited to a cylinder, and can also be a square block, or other shapes. The shape of the refrigeration element 30 is not limited to a square, and the refrigeration element 30 may also be an arc-shaped refrigeration fin adapted to the shape of the cold storage element 40. The shape of the heat dissipation element 50 is not limited to an annular column, and may also be a square block.

[0047] In this embodiment, two refrigeration components 30 are arranged outside the cold storage component 40, and the two refrigeration components 30 are respectively arranged on opposite sides of the cold storage component 40, but it is not limited thereto, and the refrigeration component 30 can also be arranged as only one, or as three or more. When there are multiple refrigeration components 30, the multiple refrigeration components 30 are preferably evenly arranged along the circumference of the cold storage component 40, so that the cold storage component 40 can be evenly cooled.

In this way, the pot cover seat 11 and the cover plate 12 can protect the fan 20, the refrigeration part 30, the cold storage part 40 and the heat sink 50, and facilitate the cleaning of the pot cover 100 and maintain the beautiful appearance of the pot cover 100. The cover plate 12 and the pot cover seat 11 can be fixedly connected by fasteners, and can also be fixedly connected by a snap-on structure, which is not limited in this application.

[0049] The fan 20 , the refrigeration component 30 , the cold storage component 40 and the heat sink 50 are all arranged in the cavity 1111 .

There are multiple air outlets 103, and the multiple air outlets 103 are arranged at intervals around the air inlet 102. In this way, cold air can pass through the refrigeration part 111 and the heat sink 50, thereby having a better refrigeration effect and a better heat dissipation effect on the hot end of the refrigeration element 30, which can extend the service life of the refrigeration element 30.

[0051] See also Figure 1 and Figure 5The air duct 101 includes a first air duct 1011, a second air duct 1012 and a third air duct 1013 which are connected in sequence. The first air duct 1011 and the third air duct 1013 are formed in the cover plate 12, and the second air duct is formed in the pot cover seat 11.

In this way, the air first enters the central area of ​​the cavity 1111 of the pot cover body 10 from the air inlet 102, then flows to the periphery of the cavity 1111, and finally flows out from the air outlet 103, so that the refrigeration part 111 can be evenly cooled, which is conducive to the condensation of steam into liquid water on the outer wall of the refrigeration part 111.

[0052] See also Figure 1 and Figure 5 The cover plate 12 includes a flat plate portion 121, an air guide column 122, an assembly boss 123 and a protective cover 81.

In some embodiments, the protective cover 81 is provided with a plurality of air outlets 103, and the plurality of air outlets 103 are arranged at intervals along the circumference of the protective cover 81, which is conducive to the hot air flowing out to the outside in time.

[0056] See also Figure 1 Furthermore, a first flexible gasket 71 is provided on one side of the cold storage component 40 and the refrigeration component 30 close to the assembly boss 123, and the cold storage component 40 and the refrigeration component 30 are both against the assembly boss 123 through the first flexible gasket 71. The provision of the first flexible gasket 71 is conducive to the cold storage component 40 and the refrigeration component 30 being tightly attached to the end surface of the assembly boss 123, so that air leakage will not occur here. In this embodiment, the first flexible gasket 71 can be made of heat insulation cotton, which can not only effectively seal the gap at the connection, but also play a heat insulation role, thereby ensuring the cold storage effect of the cold storage component 40.

[0057] For further information, see Figure 1 , Fig. 9 and Fig.10 The pot cover seat 11 also includes an annular bracket 21 and a fixing plate 72 arranged in the cavity 1111. The fan 20 is arranged on the top of the inner ring wall of the annular bracket 21. The bottom surface of the fixing plate 72 is connected and fixed to the fan 20, and is connected to the outer ring wall of the annular bracket 21 to form a closed space. The cold storage part 40 and the refrigeration part 30 are installed between the fixing plate 72 and the assembly boss 123. The heat sink 50 is sleeved on the refrigeration part 30, and the cold storage part 40, the annular bracket 21, the heat sink 50, the flat plate part 121 and the refrigeration part 111 are surrounded to form the second air duct 1012. It can be seen that the refrigeration through hole 41 of the cold storage part 40 belongs to the second air duct 1012, and the fan 20 is located in the second air duct 1012. In this way, the cold storage component 40, the refrigeration component 30, the heat dissipation component 50 and the fan 20 can be compactly installed in the cavity 1111 through the annular bracket 21 and the fixing plate 72, and a second air duct 1012 arranged along a preset path is formed in the cavity 1111, and the second air duct 1012 can fully dissipate the heat of the refrigeration part 111.

[0058] Furthermore, the fixing plate 72 is made of rigid heat-insulating material, and a second flexible gasket 73 is provided on the side of the fixing plate 72 facing the fan 20 and the bracket 21, so that the reliable installation of the cold storage component 40, the refrigeration component 30, the heat dissipation component 50 and the fan 20 can be ensured, and the heat transfer between the cold storage component 40 and the heat dissipation component 50 can be avoided, thereby ensuring the cold storage effect of the cold storage component 40. And the second flexible gasket 73 can make the fan 20 and the bracket 21 close to the fixing plate 72, thereby avoiding air leakage at the connection. In this embodiment, the second flexible gasket 73 can be made of heat-insulating cotton, which can not only effectively seal the gap at the connection, but also play a heat-insulating role, thereby ensuring the cold storage effect of the cold storage component 40.

[0059] See also Figure 1 and Figure 7 Furthermore, the pot cover seat 11 further includes a cover body 112 arranged around the outer peripheral side of the refrigeration part 111, and the cover body 112 is used to connect with the pot mouth of the pot body 200. In this way, when the pot cover 100 is covered on the pot body 200, the refrigeration part 111 is located on the inner side of the pot body 200, so that the refrigeration part 111 can cool the steam generated in the pot body 200. In this embodiment, the bottom wall of the refrigeration part 111 protrudes toward the inner side surface of the cover body 112, so that the refrigeration part 111 has a larger area to contact the steam, and has a better cooling effect on the steam.

[0060] Further, the cover body 112 includes a cover top wall 1121 and a cover side wall 1122, the cover top wall 1121 is annular, the cover side wall 1122 is conical, the inner circle of the cover top wall 1121 is connected to the outer wall of the refrigeration unit 111, the outer circle of the cover top wall 1121 is connected to the end with a larger outer diameter of the cover side wall 1122, and the end with a smaller outer diameter of the cover side wall 1122 is extended toward the refrigeration unit 111. In this way, the cover side wall 1122 can be adapted to pot bodies 200 of different sizes, thereby improving the versatility of the pot cover 100. In one embodiment, the minimum outer diameter of the cover side wall 1122 is 15 cm, and the maximum outer diameter is 30 cm, so that it can be adapted to pot bodies 200 with an inner diameter of a pot mouth in the range of 15 cm to 30 cm.

[0061] Of course, in other embodiments, the cover body 112 may also be similar to the ordinary pot cover 100, for example, the cover side wall 1122 of the cover body 112 extends vertically downward, or the cover side wall 1122 of the cover body 112 is an arc-shaped surface, or the cover body 112 as a whole is an arc-shaped surface.

[0062] See also Figure 1 and Figure 7 Further, a sealing sleeve 92 is provided on the outer side of the cover side wall 1122. This is conducive to the sealing cooperation between the pot cover 100 and the pot mouth of the pot body 200, thereby reducing the leakage of steam. In this embodiment, the sealing sleeve 92 is made of silicone material.

[0063] Furthermore, a handle 113 is provided on the cover top wall 1121 to facilitate the user to take the pot cover 100. In this embodiment, there are two handles 113, which are arranged on opposite sides of the cover top wall 1121.

[0064] See also Figure 1 , Figure 7 and Figure 8 Furthermore, a support leg 114 is provided at one end of the cover side wall 1122 away from the cover top wall 1121, and when the pot cover 100 is placed on the platform, the pot cover 100 can be supported by the support leg 114. In this embodiment, the cover side wall 1122 is provided with four support legs 114, and the four support legs 114 are evenly distributed along the circumference of the cover side wall 1122, but it is not limited thereto. In other embodiments, the number of the support legs 114 can also be two, three, five, six, and so on.

[0065] See also Figure 1Furthermore, the pot cover 100 further includes a first temperature probe 84 and a second temperature probe 85 electrically connected to the control circuit board 83. The first temperature probe 84 is used to detect the ambient temperature, and the second temperature probe 85 is used to detect the temperature inside the pot body 200. In this way, the control circuit board 83 can control the opening and closing of the fan 20 and the opening and closing of the refrigeration element 30 according to the temperature detected by the first temperature probe 84 and the second temperature probe 85. For example, at the beginning of cooking, the ambient temperature and the temperature inside the pot body 200 are both low, and the refrigeration element 30 and the fan 20 are not working, so that the food in the pot body 200 can be heated up quickly. When the soup is boiling, the refrigeration element 30 and the fan 20 are turned on, and the refrigeration part 111 is cooled, so that the steam condenses into liquid water when it contacts the refrigeration part 111, and falls back into the pot body 200, thereby reducing the evaporation loss of the soup. During the boiling process of the soup, the temperature in the pot body 200 is different at different boiling degrees. The wind force of the fan 20 can be controlled according to the boiling degree. For example, when the boiling is intense, the wind is turned on; when the boiling is slight, the wind is turned on or the fan 20 and the refrigeration element 30 are turned off. Specifically, multiple wind speeds can be set as needed, so as to accurately control the wind force of the fan 20 according to the temperature of the soup in the soup pot, so that the steam evaporation loss is small and the soup can be kept boiling.

[0066] In this embodiment, the first temperature probe 84 is disposed in the first air duct 1011 near the air inlet 102 to accurately detect the ambient temperature. The second temperature probe 85 is disposed in one of the legs 114 to accurately detect the temperature in the pot body 200 .

[0067] In this embodiment, before the entire circuit control system finishes working, it will control whether the fan 20 needs to delay working and the length of time required for the delayed working according to whether the refrigeration component 30 is turned on and the detection of the ambient temperature by the first temperature measuring probe 84. This ensures that the temperature in the air duct 101 is consistent with the ambient temperature when the entire device finishes working, thereby avoiding the generation of condensed water in the air duct 101.
