[0030] In the present utility model, the cover body 20 includes a cover cloth 21 and a cover frame 22, and the housing 10 is provided with a telescopic channel 19, and a telescopic cylinder 50 is disposed through the telescopic channel 19; by telescopically moving the telescopic cylinder 50, the cover frame 22 can be switched between a contracted state and an expanded state; when in the contracted state, the cover cloth 21 can be retracted like an umbrella, so as to facilitate storage; when in the expanded state, the cover cloth 21 opens like an umbrella and can be disposed above the table, and is used in combination with the housing 10 to provide the function of a heat preservation and fresh-keeping cover.

[0031] The refrigeration and heating of the semiconductor refrigeration and heating unit 12 is a direct application of the prior art. By changing the direction of the current, refrigeration or heating can be achieved on the same refrigeration chip. Details are not described herein again.

[0032] In some other embodiments, the semiconductor refrigeration and heating unit 12 can adopt a combination of a refrigeration chip and an independent heating and refrigeration unit with an electric heating structure.

[0033] In this embodiment, the connecting rods 51 are uniformly arranged along the circumferential direction on the telescopic cylinder 50; both ends of the connecting rods 51 are respectively hinged to the telescopic cylinder 50 and the cover frame 22. The contraction structure of the telescopic cylinder 50, the cover frame 22 and the connecting rods 51 is similar to that of a folding umbrella, and the setting of the hinge structure can be referred to that of a folding umbrella.

[0034] In this embodiment, the telescopic cylinder 50 is provided with a limiting step 52, and the limiting step 52 can abut against the end of the telescopic channel 19. Through the limiting step 52, the moving position of the telescopic cylinder 50 can be limited to prevent the telescopic cylinder 50 from detaching from the machine shell 10.

[0035] In some embodiments, the telescopic cylinder 50 is provided with an elastic limiting member 53, and the elastic limiting member 53 can abut against the end of the telescopic channel 19; by pressing the elastic limiting member 53, the abutting connection between the elastic limiting member 53 and the telescopic channel 19 can be released.

[0036] In some embodiments, in order to facilitate hoisting and pulling the telescopic cylinder 50, a rope is provided at the top of the telescopic cylinder 50.

[0037] In the prior art insurance cover, the machine body is arranged in the upper middle of the cover body 20, and the cold air or hot air of the machine body directly blows air flow downward toward the cover body 20 through the inner fan. The air flow directly blows toward the food below the cover body 20, which easily blows bacteria and dust onto the surface of the food and blows the food onto the table, resulting in a poor actual use experience for users. Therefore, further improvement is needed.

[0038] In this embodiment, the machine shell 10 is provided with a lower chamber 30, and the lower chamber 30 is located in the fresh-keeping cavity; a plurality of inner circulation air outlet holes 31 are arranged on the side of the lower chamber 30, and an inner circulation air inlet hole 32 is arranged below the lower chamber 30; the inner circulation fan 13 can suck air from the inner circulation air inlet hole 32 and send the air toward the inner circulation air outlet holes 31; the semiconductor refrigeration and heating unit 12 can refrigerate or heat the lower chamber 30. The hot air or cold air is sent out from the side of the lower chamber 30 through the semiconductor refrigeration and heating unit 12 and flows along the wall surface of the cover body 20 toward the lower part of the fresh-keeping cavity, so as to cover the food on the table; after the circulating air flow reaches the table, it flows upward and returns to the inner circulation air inlet hole 32 to be sucked into the lower chamber 30. This circulating air flow does not directly blow toward the food, and bacteria and dust are not easy to touch the food, nor is it easy to blow the food onto the table.

[0039] In this embodiment, the cover body 20 is provided with an upper chamber 40. The upper chamber 40 is provided with an external circulation fan 14 electrically connected to the circuit board 11. The upper chamber 40 is provided with an external circulation air inlet hole 42 and an external circulation air outlet hole 41. The external circulation fan 14 in the upper chamber 40 can form an external circulation air flow connecting to the outside air in the upper chamber 40 to accelerate the heat dissipation or refrigeration efficiency of the cold end and the hot end of the semiconductor refrigeration and heating unit 12.

[0040] In this embodiment, the housing 10 includes an upper shell 15, a partition 16 and a lower shell 17. The upper shell 15 and the partition 16 enclose to form the upper chamber 40, and the lower shell 17 and the partition 16 enclose to form the lower chamber 30. The housing 10 is separately provided as the upper shell 15, the partition 16 and the lower shell 17, which can be conveniently assembled to form the structures of the upper chamber 40 and the lower chamber 30.

[0041] Furthermore, the upper shell 15 and the lower shell 17 are symmetrically arranged relative to the partition 16. With the symmetrically arranged structures of the upper shell 15 and the lower shell 17, the same housing can be used for assembly, reducing the types of materials and the production and preparation costs.

[0042] In this embodiment, in order to accelerate the heat dissipation and refrigeration efficiency of the semiconductor refrigeration and heating unit 12, the semiconductor refrigeration and heating unit 12 is embedded in the partition 16. Heat exchange fins 18 are arranged on the upper and lower sides of the semiconductor refrigeration and heating unit 12. The external circulation fan 14 is arranged close to the heat exchange fin 18 on the upper side, and the internal circulation fan 13 is arranged close to the heat exchange fin 18 on the lower side.

[0043] In this embodiment, the circuit board 11 is arranged in the upper chamber 40. The electronic components of the circuit board 11 and the control panel are arranged in the upper chamber 40, and only the internal circulation fan 13 is arranged in the lower chamber 30, which can make the circulation air flow in the fresh-keeping chamber and the lower chamber 30 more uniform and smooth, reducing the existence of blocking components.

[0044] Certainly, the present invention is not limited to the above embodiments. Those skilled in the art can make equivalent deformations or replacements without departing from the spirit of the present invention, and these equivalent deformations and replacements are all included in the scope defined by the claims of this application.
