Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. Furthermore, the technical features mentioned in the embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

Fig. 2 is a schematic structural view of a refrigeration showcase according to an embodiment of the present invention. As shown in fig. 2, the refrigerated showcase 10 includes a refrigerating chamber 20 and a machine chamber 30 positioned at one side of the refrigerating chamber 20, wherein the refrigerating chamber 20 and the machine chamber 30 are partitioned by a shelf 40. The refrigerating chamber 20 is mainly constituted by a side plate 106, a back plate 109, the shelf 40, glass 102 (see fig. 3), and two cross members 112(113), and the machine chamber 30 is mainly constituted by a side plate 107, the back plate 109, the shelf 40, a bottom plate 110, and the two cross members 112 (113).

The machine chamber 30 is provided with a compressor 301, a condenser (not shown), a fan (not shown), and the like, wherein the compressor 301, the condenser (not shown), and the like constitute a refrigeration system in the machine chamber 30. The side plate 107 of the machine chamber 30 is provided with a heat radiation port 111.

An upper cooling chamber 201 is provided in the refrigerating chamber 20, the upper cooling chamber 201 may be mounted on the upper portion of the back plate 109, and an opening 2011 (see fig. 3) of the upper cooling chamber 201 faces the refrigerating chamber 20. The upper cooling chamber 210 is provided with an upper evaporator 101, and the upper evaporator 101 cools the air in the upper cooling chamber 201 so that the cooled air flows into the refrigerating chamber 20 through the opening 2011, and convection is formed in the refrigerating chamber 20 by a difference in specific gravity between cold air and hot air (the cold air has a specific gravity higher than that of the hot air).

The upper compartment 210 also has an upper evaporator mounting bracket 1012 for mounting the upper evaporator 101. Preferably, the upper evaporator 101 is mounted on the upper cooling compartment 210 by the mounting bracket 1012 on both side plates to facilitate the mounting of the upper evaporator 101.

The shelf 40 has a through hole 401, and the tube 1011 of the upper evaporator 101 communicates with the tube 3012 of the refrigeration system in the machine room 30 through the through hole 401.

The refrigerating chamber 20 has an opening 108 at the bottom thereof, the opening 108 is covered with a stainless steel plate 104, and the upper portion of the stainless steel plate 104 is communicated with the refrigerating chamber 20 through the opening 108.

A lower evaporator 103 is provided at the bottom of the stainless steel tray 104, and the lower evaporator 103 is closely attached to the bottom of the stainless steel tray 104, thereby cooling the air at the lower portion of the refrigerating chamber 20 through the stainless steel tray 104.

The tube 1031 of the lower evaporator 103 communicates with the tube 3012 of the refrigeration system in the machine room 30 through the through hole 1101 in the bottom plate 110 of the machine room 30.

The compressor 301 and the condenser, the lower evaporator 103, and the upper evaporator 101 in the machine chamber 30 are connected to each other in a circulating manner through pipes.

Fig. 3 is a schematic sectional view of a refrigeration showcase according to an embodiment of the present invention. As shown in fig. 3, the upper cooling compartment 201 is installed on the upper portion of the back plate 109, and the air cooled by the upper evaporator 101 in the upper cooling compartment 210 flows into the refrigerating compartment 20 through the opening 2011. Since the cold air has a higher specific gravity than the hot air, the cold air sinks in the upper part of the refrigerating compartment 20, and the hot air rises in the lower part of the refrigerating compartment 20, thereby forming convection in the refrigerating compartment 20.

The stainless steel plate 104 is hermetically installed on the cross member 112 and the cross member 113 to seal the opening 108, and the lower evaporator 103 closely attached to the bottom of the stainless steel plate 104 generates a cooling effect on the stainless steel plate 104, so that the generated cooling capacity is transferred to the air at the lower portion of the refrigerating compartment 20 through the stainless steel plate 104, thereby overcoming a problem that the cooling capacity at the bottom of the refrigerating compartment 20 is insufficient due to the loss of the cooling capacity during the sinking process of the cold air generated by the upper evaporator 101 of the upper refrigerating compartment 201.

In the above embodiment, in order to prevent the loss of the cold energy generated by the lower evaporator 103, the heat insulating layer 105 is wrapped around the lower evaporator 103 and the stainless steel plate 104. Preferably, the heat insulating layer 105 is a foam material layer.

In the above embodiment, a cabinet door 1091 is provided on the back plate 109, and the cabinet door 1091 is used to place and remove the items in the refrigerating compartment 20.

In the above embodiment, the machine room 30 is located beside the refrigerating room 20. However, the present invention is not limited thereto, and the machine room 30 may be located below the refrigerating room 20.
