[0046] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0047] In the prior art, generally, an independent refrigeration system and a heating system are arranged in a display cabinet, and the refrigeration compartment and / or the heating compartment are refrigerated through the refrigeration system, and the heating compartment is heated through the heating system. In this way, the heating compartment of the display cabinet can be in a high-temperature, normal-temperature, or low-temperature state through the cooperation of the refrigeration system and the heating system, increasing the utilization rate of the display cabinet.

[0048] In the related prior art, an air duct is provided between the heating compartment and the cooling compartment in a hot-cold conversion display cabinet. The cold air in the cooling compartment can flow into the heating compartment through the air duct, and at the same time, the air flow in the heating compartment can also flow into the cooling compartment through the air duct to achieve air flow circulation. However, during air flow circulation, the air flow flowing from the cooling compartment into the heating compartment and the air flow flowing from the heating compartment into the cooling compartment share the same air duct, which may cause air flow disorder, thereby affecting the flow rate and flow volume of the cold air flowing into the heating compartment.

[0049] As Figures 1 to 9 shown, an embodiment of the present disclosure provides a hot-cold conversion display cabinet. After the cold air of the refrigeration system 01 flows into the first compartment 101, the air flow in the first compartment 101 can also flow out of the first compartment 101 in time to avoid affecting the flow rate and flow volume of the cold air flowing into the first compartment 101.

[0050] As Figure 1 and Figure 9 shown, an embodiment of the present disclosure provides a hot-cold conversion display cabinet, including: a cabinet body 10, a heating system 02, a refrigeration system 01, and an air duct plate 20. The cabinet body 10 is provided with a first compartment 101 and a second compartment 102; the heating system 02 is arranged in the cabinet body 10 for heating the first compartment 101; the refrigeration system 01 is arranged in the cabinet body 10; the air duct plate 20 is arranged in the cabinet body 10, and the air duct plate 20 includes a first air inlet duct 21 and a connecting air duct 23. Wherein, the connecting air duct 23 includes a connecting air inlet 231 and a connecting air outlet 232 respectively communicating with the first compartment 101 and the second compartment 102; the first air inlet duct 21 includes a refrigeration air inlet communicating with the refrigeration system 01, a first refrigeration air outlet 211 communicating with the first compartment 101, and a second refrigeration air outlet 212 communicating with the second compartment 102.

[0051] Specifically, the cabinet body 10 includes an installation cavity and a storage cavity. A partition 30 is arranged in the storage cavity, and the partition 30 is used to divide the storage cavity into independent first compartment 101 and second compartment 102. The heating system 02 is installed at a position corresponding to the first compartment 101 in the installation cavity, and the refrigeration system 01 is installed at a position corresponding to the second compartment 102 in the installation cavity. The air duct plate 20 is further provided with a return air duct, and the return air duct includes a return air inlet communicating with the second compartment 102 and a return air outlet. Wherein, the return air outlet can communicate with the external environment or with the air inlet end of the fan 03.

[0052] The refrigeration system 01 includes a refrigeration device and a blower 03, and the air outlet end of the blower 03 is communicated with the refrigeration air inlet of the first air inlet duct 21. In this way, the blower 03 can blow the cold air generated by the refrigeration device to the first chamber 101 and / or the second chamber 102 through the first air inlet duct 21. After the cold air flows through the first chamber 101, it can flow into the second chamber 102 through the connecting duct 23 and flow to the external environment or the air inlet end of the blower 03 through the return air duct to realize air circulation, as Figure 6 shown.

[0053] With such a setting, after the cold air of the refrigeration system 01 flows into the first chamber 101, the air flow in the first chamber 101 can also flow out of the first chamber 101 in time to avoid affecting the flow rate and flow volume of the cold air flowing into the first chamber 101.

[0054] Optionally, air doors 24 are respectively arranged at the first refrigeration air outlet 211 and the connecting duct 23. In this way, the temperature of the first chamber 101 and / or the second chamber 102 can be controlled by controlling the opening degree of the air door 24.

[0055] When both the refrigeration system 01 and the heating system 02 are turned on, the air doors 24 of the first refrigeration air outlet 211 and the connecting duct 23 can be closed. At this time, the first chamber 101 is in a high-temperature state; the air door 24 of the first refrigeration air outlet 211 can also be opened and the air door 24 of the connecting duct 23 can be closed. At this time, the first chamber 101 is in a normal-temperature state.

[0056] When the refrigeration system 01 is turned on and the heating system 02 is turned off, the air doors 24 of the first refrigeration air outlet 211 and the connecting duct 23 can be opened. At this time, the cold air of the refrigeration system 01 can flow into the first chamber 101. At this time, the first chamber 101 is in a low-temperature state. At the same time, the air flow in the first chamber 101 can flow into the second chamber 102 through the connecting duct 23 to complete air circulation.

[0057] As Figure 2 shown, in some embodiments, the above-mentioned first chamber 101 is located above the second chamber 102, and the height of the above-mentioned connecting air inlet 231 is lower than the height of the above-mentioned first refrigeration air outlet 211.

[0058] Specifically, at least one first refrigeration air outlet 211 is arranged at the position of the air duct plate 20 corresponding to the upper half of the first chamber 101. In this way, after the cold air flows into the first chamber 101 through the above-mentioned first refrigeration air outlet 211, the cold air can naturally flow downward through the entire first chamber 101, thereby increasing the refrigeration efficiency of the first chamber 101.

[0059] It can be understood that setting the first chamber 101 above the second chamber 102 and making the height of the connecting air inlet 231 lower than the height of the first refrigeration air outlet 211 can cause the cold air in the first chamber 101 to flow naturally downward to the second chamber 102, so as to accelerate the speed of air flow circulation.

[0060] In the above embodiment, the height of the connecting air inlet 231 refers to the distance from the connecting air inlet 231 to the partition 30, and the height of the first refrigeration air outlet 211 refers to the distance from the first refrigeration air outlet 211 to the partition 30.

[0061] In some embodiments, the air duct plate 20 is provided with a plurality of first air inlet ducts 21, and the plurality of first air inlet ducts 21 are arranged horizontally on the air duct plate 20.

[0062] Specifically, when the refrigeration system 01 is turned on, the cold air generated by the refrigeration system 01 can flow into the first chamber 101 and / or the second chamber 102 through the plurality of first air inlet ducts 21 respectively. With such a setting, the amount of cold air flowing into the first chamber 101 and / or the second chamber 102 can be controlled by controlling the opening or closing of the air valves 24 of each first air inlet duct 21, thereby controlling the number of unblocked first air inlet ducts 21. At the same time, by delivering the cold air to the first chamber 101 and the second chamber 102 through the plurality of first air inlet ducts 21, the plurality of positions in the first chamber 101 and the second chamber 102 can be cooled simultaneously, thereby improving the refrigeration efficiency of the first chamber 101 and the second chamber 102.

[0063] In practical applications, the user can determine the number of the first air inlet ducts 21 according to actual needs. For example, the number of the first air inlet ducts 21 can be 2, 3, 4, 5 or 6.

[0064] Optionally, the number of the first air inlet ducts 21 is an even number, and the number of the first air inlet ducts 21 provided on the left half and the right half of the air duct plate 20 is the same.

[0065] Optionally, when the air duct plate 20 is provided with a plurality of first air inlet ducts 21, the plurality of first air inlet ducts 21 are respectively provided with air valves 24. With such a setting, the amount of cold air flowing into the first chamber 101 and / or the second chamber can be controlled by respectively controlling the opening or closing of the air valves 24 of the plurality of first air inlet ducts 21.

[0066] As Figure 5 shown, in some embodiments, the air duct plate 20 is provided with two of the first air inlet ducts 21, and the two first air inlet ducts 21 are respectively arranged on the left and right sides of the connecting air duct 23.

[0067] Specifically, the connecting air duct 23 is vertically arranged in the middle of the air duct plate 20, and one first air inlet duct 21 is vertically arranged in the left half of the air duct plate 20. The other first air inlet duct 21 is vertically arranged in the right half of the air duct plate 20. In this way, the refrigeration system 01 can refrigerate the left half of the first compartment 101 and the second compartment 102 through the first air inlet duct 21 in the left half of the air duct plate 20, and refrigerate the right half of the first compartment 101 and the second compartment 102 through the first air inlet duct 21 in the right half of the air duct plate 20. At the same time, the cold air in the left half and the right half of the first compartment 101 can converge towards the middle and flow into the second compartment 102 through the connecting air duct 23 in the middle of the air duct plate 20. With such an arrangement, the uniformity of the cold air flowing into the first compartment 101 and the second compartment 102 can be further increased.

[0068] As Figure 2 and Figure 3 shown, in some embodiments, the above-mentioned first air inlet duct 21 is provided with a plurality of the above-mentioned first refrigeration air outlets 211 and a plurality of the above-mentioned second refrigeration air outlets 212.

[0069] Specifically. By providing a plurality of first refrigeration air outlets 211 and a plurality of second refrigeration air outlets 212 in the first air inlet duct 21, the first compartment 101 and the second compartment 102 can be refrigerated respectively through the plurality of first refrigeration air outlets 211 and the plurality of second refrigeration air outlets 212, and the refrigeration efficiency of the refrigeration system 01 for the first compartment 101 and the second compartment 102 can be further increased. At the same time, by providing a plurality of first refrigeration air outlets 211 and a plurality of second refrigeration air outlets 212, the size of a single refrigeration air outlet can be avoided from being too large while ensuring the same amount of cold air, thereby avoiding local over-low temperature.

[0070] In practical applications, the user can set the number of the first refrigeration air outlets 211 and the second refrigeration air outlets 212 according to actual needs. For example, the user can set 2, 3, 4, 5 or 6 first refrigeration air outlets 211; similarly, the user can also set 2, 3, 4, 5 or 6 second refrigeration air outlets 212.

[0071] As Figure 2 and Figure 3 shown, in some embodiments, at least some of the above-mentioned first refrigeration air outlets 211 are arranged in the vertical direction; and / or, at least some of the above-mentioned second refrigeration air outlets 212 are arranged in the vertical direction.

[0072] Specifically, when multiple first refrigeration air outlets 211 are provided in the first air inlet duct 21, at least some of the first refrigeration air outlets 211 are arranged in the vertical direction. Such an arrangement can further increase the uniformity of the cold air flowing into the first compartment 101. Similarly, when multiple second refrigeration air outlets 212 are provided in the second air inlet duct 22, at least some of the second refrigeration air outlets 212 are arranged in the vertical direction to further increase the uniformity of the cold air flowing into the first compartment 101.

[0073] In some specific embodiments, two first refrigeration air outlets 211 are provided in the first air inlet duct 21. One first refrigeration air outlet 211 is arranged in the upper half of the first compartment 101, and the other first refrigeration air outlet 211 is arranged in the middle of the first compartment 101. In this way, cold air can flow into the upper half and the middle of the first compartment 101 simultaneously. Similarly, two second refrigeration air outlets 212 are provided in the first air inlet duct 21. One second refrigeration air outlet 212 is arranged in the upper half of the second compartment 102, and the other second refrigeration air outlet 212 is arranged in the middle of the second compartment 102 to refrigerate the upper half and the middle of the second compartment 102 simultaneously.

[0074] In some other specific embodiments, three first refrigeration air outlets 211 are provided in the first air inlet duct 21. The three first refrigeration air outlets 211 are respectively arranged in the upper half, the middle, and the lower half of the first compartment 101 so that cold air can flow into the upper half, the middle, and the lower half of the first compartment 101 simultaneously. Similarly, three second refrigeration air outlets 212 are provided in the first air inlet duct 21. The three second refrigeration air outlets 212 are respectively arranged in the upper half, the middle, and the lower half of the second compartment 102 so that cold air can flow into the upper half, the middle, and the lower half of the second compartment 102 simultaneously.

[0075] As Figure 4 and Figure 8 shown, in some embodiments, the air duct plate 20 is further provided with a second air inlet duct 22 communicating with the first compartment 101; the heating system 02 includes: a heating device 04 and a blower 03. The heating device 04 is arranged in the second air inlet duct 22; the blower 03 is arranged in the second air inlet duct 22, and the air supply direction of the blower 03 is defined to be towards the first compartment 101.

[0076] Specifically, when the heating device 04 is turned on, the blower 03 can blow the hot air generated by the heating device 04 into the first compartment 101 to heat the first compartment 101.

[0077] In practical applications, the heating device 04 can be a heat exchanger or an electric heating element as long as it can achieve heating.

[0078] Optionally, a damper 24 is provided in the second air inlet duct 22.

[0079] As Figure 4 shown, in some embodiments, the cold and heat conversion display cabinet further includes: a wind deflector 40. The wind deflector 40 is disposed in the second air inlet duct 22, and the wind deflector 40 is located between the heating system 02 and the first compartment 101.

[0080] Specifically, the wind deflector 40 is disposed on one side of the heating system 02 facing the first compartment 101, and a plurality of ventilation openings are evenly distributed along the length direction of the wind deflector 40. When the hot air generated by the heating system 02 flows into the first compartment 101, the wind deflector 40 can guide the hot air to increase the blowing distance of the hot air, thereby avoiding too high temperature at the position of the first compartment 101 close to the air duct and too low temperature at the position close to the door body.

[0081] In some embodiments, the angle between the wind deflector 40 and the horizontal plane is greater than or equal to 30° and less than or equal to 80°.

[0082] Specifically, the angle between the wind deflector 40 and the horizontal plane can be 30°, 45°, 60° or 80°. In this way, the blowing distance of the air flow can be further increased.

[0083] As Figure 3 shown, in some embodiments, the second air inlet duct 22 is provided with a heating air outlet 221 communicating with the first compartment 101; the cold and heat conversion display cabinet further includes: a protection plate 50. The protection plate 50 is installed at a position corresponding to the first compartment 101 and the heating air outlet 221.

[0084] Specifically, the protection plate 50 is fixedly installed at a position corresponding to the first compartment 101 and the heating air outlet 221, and the size of the protection plate 50 is greater than or equal to the size of the heating air outlet 221. In this way, when the heating system 02 heats the first compartment 101, the protection plate 50 can prevent users from reaching their hands into the second air inlet duct 22 and getting scalded.
