[0045] The term "and / or" is an associative relationship describing objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[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 chamber and / or the heating chamber are refrigerated through the refrigeration system, and the heating chamber is heated through the heating system. In this way, through the cooperation of the refrigeration system and the heating system, the heating chamber of the display cabinet can be in a high temperature, normal temperature or low temperature state, 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 and 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 circulation. However, the refrigeration system of the existing hot and cold conversion display cabinet cools the corresponding compartment through a single air duct, and can only control the amount of cold air flowing in by the damper in the air duct. The control method is single and the user experience is not good.

[0049] As Figures 1 to 9 shown, an embodiment of the present disclosure provides a hot and cold conversion display cabinet. The cold air of the refrigeration system 01 can respectively cool the first compartment 101 and / or the second compartment 102 through a plurality of first air inlet ducts 21. Therefore, the amount of cold air flowing into the first compartment 101 and the second compartment 102 can be controlled by controlling the number of the first air inlet ducts 21 that are unblocked or blocked.

[0050] As Figures 1 to 9 shown, an embodiment of the present disclosure provides a hot and 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 and is used 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 is provided with a plurality of first air inlet ducts 21, and a damper 24 is respectively arranged on the plurality of first air inlet ducts 21; wherein, the first air inlet duct 21 includes a refrigeration air inlet connected to the refrigeration system 01, a first refrigeration air outlet 211 connected to the first compartment 101, and a second refrigeration air outlet 212 connected to 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 for separating the storage cavity into two 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 connected to the second compartment 102 and a return air outlet. Wherein, the return air outlet can be connected to the external environment or to 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 inlets of a plurality of first air inlet ducts 21. In this way, the blower 03 can blow the cold air generated by the refrigeration device to the first compartment 101 and / or the second compartment 102 through the plurality of first air inlet ducts 21. By setting like this, the opening or closing of the air doors 24 of each of the first air inlet ducts 21 can be controlled, and then the number of the unblocked first air inlet ducts 21 can be controlled to control the amount of cold air flowing into the first compartment 101 and / or the second compartment 102. At the same time, by delivering the cold air to the first compartment 101 and the second compartment 102 through the plurality of first air inlet ducts 21, the plurality of positions in the first compartment 101 and the second compartment 102 can be cooled simultaneously, thereby improving the refrigeration efficiency of the first compartment 101 and the second compartment 102.

[0053] When both the refrigeration system 01 and the heating system 02 are turned on, the air door 24 of the first air inlet duct 21 can be closed, and at this time, the first compartment 101 is in a high-temperature state; or the air door 24 of the first air inlet duct 21 can be opened, and at this time, the first compartment 101 is in a normal-temperature state.

[0054] When the refrigeration system 01 is turned on and the heating system 02 is turned off, the air door 24 of the first air inlet duct 21 can be opened, and the cold air of the refrigeration system 01 can flow into the first compartment 101. At this time, the first compartment 101 is in a low-temperature state.

[0055] 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.

[0056] As Figure 2 and Figure 3 shown, in some embodiments, the plurality of above-mentioned first air inlet ducts 21 are arranged horizontally on the above-mentioned air duct plate 20, and the distance between adjacent above-mentioned first air inlet ducts 21 is the same.

[0057] Specifically, arranging the plurality of first air inlet ducts 21 horizontally can enable the refrigeration system 01 to cool the plurality of positions in the first compartment 101 and the second compartment 102 simultaneously through the plurality of first air inlet ducts 21. At the same time, making the distance between adjacent above-mentioned first air inlet ducts 21 the same can prevent too many first air inlet ducts 21 from being arranged at the same position, thereby avoiding uneven temperature in the first compartment 101 and the second compartment 102.

[0058] As Figure 3 shown, in some embodiments, at least one of the above-mentioned first air inlet ducts 21 is arranged on both the left half and the right half of the above-mentioned air duct plate 20.

[0059] Specifically, at least one first air inlet duct 21 is provided in the left half and the right half of the air duct plate 20. In this way, the refrigeration system 01 can refrigerate the left half and the right half of the first compartment 101 and the second compartment 102 respectively through the first air inlet ducts 21 in the left half and the right half of the air duct plate 20, so as to increase the uniformity of the cold air flowing into the first compartment 101 and the second compartment 102.

[0060] In some practical applications, one first air inlet duct 21 is provided in both the left half and the right half of the air duct plate 20. 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.

[0061] In other practical applications, one first air inlet duct 21 is provided in the left half, the middle part, and the right half of the air duct plate 20. 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, refrigerate the middle part of the first compartment 101 and the second compartment 102 through the first air inlet duct 21 in the middle part 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.

[0062] In practical applications, the user can open the air door 24 of the first air inlet duct 21 in the left half of the air duct plate 20 and close the air door 24 of the first air inlet duct 21 in the right half of the air duct plate 20, so that the temperature of the left half of the first compartment 101 and the second compartment 102 is lower than that of the right half. Similarly, the user can also open the air door 24 of the first air inlet duct 21 in the right half of the air duct plate 20 and close the air door 24 of the first air inlet duct 21 in the left half of the air duct plate 20, so that the temperature of the left half of the first compartment 101 and the second compartment 102 is higher than that of the right half.

[0063] In some embodiments, a plurality of the first air inlet ducts 21 are provided in the left half of the air duct plate 20; a plurality of the first air inlet ducts 21 are provided in the right half of the air duct plate 20.

[0064] Specifically, by respectively providing a plurality of first air inlet ducts 21 in the left half and the right half of the air duct plate 20, the refrigeration efficiency of the refrigeration system 01 for the left half and the right half of the first compartment 101 and the second compartment 102 can be increased.

[0065] Such as Figure 3 and Figure 5As shown, in some embodiments, the air duct plate 20 is further provided with a communicating air duct 23. The communicating air duct 23 includes a communicating air inlet 231 and a communicating air outlet 232 that are respectively communicated with the first compartment 101 and the second compartment 102.

[0066] Specifically, after the cold air flows through the first compartment 101, it can flow into the second compartment 102 through the communicating air duct 23 and flow to the external environment or the air inlet end of the fan 03 through the return air duct to achieve air flow circulation.

[0067] It can be understood that in the related prior art, in the cold and heat conversion display cabinet, when the air flow circulates, the air flow flowing from the refrigerating compartment to the heating compartment and the air flow flowing from the heating compartment to the refrigerating compartment share the same air duct, which may cause air flow disorder and thus affect the flow rate and flow volume of the cold air flowing into the heating compartment. By using the cold and heat conversion display cabinet provided in the present application, 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.

[0068] As Figure 2 and Figure 3 shown, optionally, the first compartment 101 is located above the second compartment 102, and the height of the communicating air inlet 231 is lower than the height of the first refrigeration air outlet 211. At least one first refrigeration air outlet 211 is provided at a position corresponding to the upper half of the first compartment 101 on the air duct plate 20. In this way, after the cold air flows into the first compartment 101 through the first refrigeration air outlet 211, the cold air can naturally flow downward through the entire first compartment 101, thereby increasing the refrigeration efficiency of the first compartment 101.

[0069] It can be understood that setting the first compartment 101 above the second compartment 102 and making the height of the communicating air inlet 231 lower than the height of the first refrigeration air outlet 211 can make the cold air in the first compartment 101 flow naturally downward to the second compartment 102 to accelerate the air flow circulation speed.

[0070] In the above embodiment, the height of the communicating air inlet 231 refers to the distance from the communicating 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.

[0071] As Figure 5 shown, in some embodiments, the communicating air duct 23 is vertically provided in the middle of the air duct plate 20.

[0072] Specifically, the connecting air duct 23 is vertically arranged in the middle of the air duct plate 20, and at least one first air inlet duct 21 is vertically arranged in the left half of the air duct plate 20, and at least one 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 cool the left half of the first compartment 101 and the second compartment 102 through the first air inlet ducts 21 in the left half of the air duct plate 20, and cool the right half of the first compartment 101 and the second compartment 102 through the first air inlet ducts 21 in the right half of the air duct plate 20. At the same time, the cold air in the left and right halves 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.

[0073] Optionally, a plurality of the first refrigeration air outlets 211 and a plurality of the second refrigeration air outlets 212 are arranged in the first air inlet duct 21.

[0074] Specifically, arranging a plurality of the first refrigeration air outlets 211 and a plurality of the second refrigeration air outlets 212 in the first air inlet duct 21 can cool the first compartment 101 and the second compartment 102 through the plurality of the first refrigeration air outlets 211 and the plurality of the second refrigeration air outlets 212 respectively, 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, arranging a plurality of the first refrigeration air outlets 211 and a plurality of the second refrigeration air outlets 212 can avoid the size of a single refrigeration air outlet being too large while ensuring the same amount of cold air, thereby avoiding local over-cooling.

[0075] 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.

[0076] As Figure 5 shown, in some embodiments, the first air inlet ducts 21 in the left half of the air duct plate 20 and the first air inlet ducts 21 in the right half of the air duct plate 20 are symmetrically arranged on both sides of the connecting air duct 23.

[0077] Specifically, the distance from the first air inlet duct 21 in the left half of the air duct plate 20 to the connecting air duct 23 is the same as the distance from the first air inlet duct 21 in the right half of the air duct plate 20 to the connecting air duct 23, so as to further increase the uniformity of the cold air flowing into the first compartment 101 and the second compartment 102.

[0078] As Figure 4 and Figure 5As 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 disposed in the second air inlet duct 22; the blower 03 is disposed 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.

[0079] Specifically, the second air inlet duct 22 is provided with a heating air outlet 221 communicating with the first compartment 101. 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 through the heating air outlet 221 to heat the first compartment 101.

[0080] In practical applications, the heating device 04 can be a heat exchanger or an electric heating element, as long as it can achieve the heating function.

[0081] Optionally, the second air inlet duct 22 is provided with a damper 24.

[0082] As Figure 4 shown, in some embodiments, the above-mentioned cold and hot conversion display cabinet further includes: a wind guide plate 40. The wind guide plate 40 is disposed in the second air inlet duct 22, and the wind guide plate 40 is located between the heating system 02 and the first compartment 101.

[0083] Specifically, the wind guide plate 40 is disposed on one side of the heating system 02 facing the first compartment 101, and the wind guide plate 40 is evenly provided with a plurality of ventilation openings along the length direction. When the hot air generated by the heating system 02 flows into the first compartment 101, the wind guide plate 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.

[0084] Optionally, the included angle between the wind guide plate 40 and the horizontal plane is greater than or equal to 30° and less than or equal to 80°.

[0085] Specifically, the included angle between the wind guide plate 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.

[0086] As Figure 3 shown, optionally, the second air inlet duct 22 is provided with a heating air outlet 221 communicating with the first compartment 101; the cold and hot conversion display cabinet further includes: a protection plate 50. The protection plate 50 is installed at a position corresponding to the heating air outlet 221 of the first compartment 101.

[0087] Specifically, the protection plate 50 is fixedly installed at a position corresponding to the first chamber 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 chamber 101, the protection plate 50 can prevent users from reaching their hands into the second air inlet duct 22 and getting scalded.

[0088] The above description and the drawings fully illustrate the disclosed embodiments of the present application, enabling those skilled in the art to practice them.
