[0034] Please refer to Figures 1 to 5 As shown, it shows the specific structure of a preferred embodiment of the utility model, including a cabinet 10, a controller 20, a cabinet door 30 and a refrigeration module 40.

[0035] The cabinet 10 has a receiving chamber 11 and an installation chamber 12. The opening of the receiving chamber 11 faces forward. A plurality of layers 13 arranged in an upper and lower interval are arranged in the receiving chamber 11. The plurality of layers 13 divide the receiving chamber 11 into a plurality of placement spaces 111. The installation chamber 12 has a cold air outlet 121 and a return air outlet 122. The cold air outlet 121 and the return air outlet 122 are separated from each other and are both connected to the receiving chamber 11, and the installation chamber 12 is connected to the outside. In this embodiment, the layer 13 is a stainless steel perforated layer with a simple structure to avoid water accumulation. A water collecting tray 14 is arranged at the bottom of the receiving chamber 11. The water collecting tray 14 is located below the plurality of receiving spaces 111 to collect condensed water.

[0036] The controller 20 is disposed on the cabinet 10 and has a control panel 21 . The control panel 21 is exposed from the lower front side of the cabinet 10 .

[0037] The cabinet door 30 can open or close the opening of the accommodating cavity 11. Specifically, the cabinet door 30 includes a fixed door panel 31 and a movable door panel 32. The fixed door panel 31 is fixed in the opening of the accommodating cavity 11. The movable door panel 32 is arranged to be movable back and forth relative to the fixed door panel 31. A driving mechanism 50 is arranged on the cabinet body 10. The driving mechanism 50 drives the movable door panel 32 to move back and forth relative to the fixed door panel 31 to open or close the accommodating cavity 11. The driving mechanism 50 is electrically connected to the controller 20. An infrared sensor 61 is arranged on the top front side of the cabinet body 10. The infrared sensor 61 is electrically connected to the controller 20. In this embodiment, the fixed door panel 31 and the movable door panel 32 are both heated glass, and the heated glass is electrically connected to the controller 20, so that the items in the accommodating cavity 11 can be seen through the fixed door panel 31 and the movable door panel 32, and at the same time, the fixed door panel 31 and the movable door panel 32 are prevented from fogging easily, which affects the display effect of the items. Furthermore, the upper and lower ends of the movable door plate 32 are slidably connected to the cabinet 10 through the pulley 62, and the movement is smooth. The driving mechanism 50 includes a rack 51, a motor 52 and a gear 53. The rack 51 is fixed to the upper end of the movable door plate 32 and extends left and right. The motor 52 is fixed to the inner top of the cabinet 10. The motor 52 is electrically connected to the controller 20. The gear 53 is fixed to the output shaft of the motor 52 and meshes with the rack 51. Furthermore, the cabinet door 20 is symmetrically arranged in two, and a driving mechanism 50 and an infrared sensor 61 are provided for each cabinet door 20 so that they can be opened and closed separately, which is more convenient to use.

[0038] The refrigeration module 40 is disposed in the installation cavity 12 and is electrically connected to the controller 20. The refrigeration module 40 is composed of a compressor 41, an evaporator 42, and a fan 43. The specific structure and working principle of the refrigeration module 40 are all prior art. The specific structure and working principle of the refrigeration module 40 are not described in detail herein.

[0039] In addition, a lighting device 63 is disposed on the top of each placement space 111 . The lighting device 63 is electrically connected to the controller 20 to provide a lighting function for better display. The lighting device 63 is an LED lamp.

[0040] The working principle of this embodiment is described in detail as follows:

[0041] During use, when the controller 20 is powered on, the refrigeration module 40 generates cold air, which enters the accommodating chamber 11 from the cold air outlet 121, so that the temperature in the accommodating chamber 11 is reduced, and then the airflow flows back to the refrigeration module 40 from the return air outlet 122. At this time, the items can be placed on the shelf 13 of the accommodating chamber 11 for refrigeration. During use, when the infrared sensor 61 senses that someone is approaching the display cabinet, the infrared sensor 61 sends a door opening command to the controller 20, and the controller 20 controls the drive mechanism 50 to work, and the drive mechanism 50 drives the movable door plate 32 to move and open the opening of the accommodating chamber 11. At this time, it is convenient for people to take out or put in items. When the infrared sensor 61 does not sense that someone is approaching the display cabinet for a period of time, the infrared sensor 61 sends a door opening command to the controller 20, and the controller 20 controls the drive mechanism 50 to work, and the drive mechanism 50 drives the movable door plate 32 to move in the opposite direction and completely close the opening of the accommodating chamber 11.

[0042] The design focus of the utility model is that an infrared sensor and a driving mechanism are provided in combination, and the infrared sensor is used to sense whether a person is approaching the display cabinet. When the user approaches the display cabinet, the infrared sensor sends a command to the controller, and the controller controls the driving mechanism to work, and then the driving mechanism drives the movable door panel to move, thereby opening the accommodating cavity for the purpose of taking and placing items. Conversely, the driving mechanism drives the movable door panel to move in the opposite direction to close the accommodating cavity, thereby realizing the automatic opening and closing of the cabinet door, replacing the traditional manual switch method, and bringing great convenience to use.

[0043] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
