Description

Technical Field

[0001] The utility model relates to the technical field of food preservation equipment, in particular to a back-air outlet type refrigerator. Background Art

[0002] During the milk tea making process, the tea soup is usually put into a storage container and then placed in a refrigerator for refrigeration. In existing milk tea shops, refrigerators are generally air-cooled. Figure 1 As shown, the refrigerated storage chamber in the refrigerator is used to accommodate storage containers. Its shape is generally a rectangular parallelepiped. For easy placement and use, the refrigerator usually has one long side (the two opposite sides along the width direction, generally referred to as the front and rear sides of the refrigerated storage chamber). The cold air production equipment is generally set on the left or right side (i.e., the short side) of the refrigerator, and a cold air blowing port is set on the left or right side of the refrigerated storage chamber for the entry of cold air. The refrigerated storage chamber generally stores multiple storage containers, and the storage containers are arranged along the length of the refrigerated storage chamber. When cold air enters from the short side of the refrigerated storage chamber, the airflow will be blocked by the storage containers close to the cold air blowing port, making it difficult for the cold air to smoothly reach the storage containers far away from the cold air blowing port. This phenomenon is more obvious when the refrigerated storage chamber is long, resulting in the problem of uneven temperature at various locations along the length of the refrigerated storage chamber. The storage containers on the side far away from the cold air blowing port are difficult to be effectively cooled. Utility Model Content

[0040] See also Figures 1 to 6The present invention provides a back-air outlet refrigerator, including a refrigerated storage chamber 1. For the convenience of explanation, in this application, the length direction of the refrigerated storage chamber 1 is the left-right direction, and the width direction is the front-to-back direction, that is, the two long sides of the refrigerated storage chamber 1 are the front and back sides, and the two short sides are the left and right sides. The back-air outlet refrigerator also includes a cooling pipe assembly 4 and a fan 2, both of which are arranged in the refrigerated storage chamber 1. A cooling area is provided at the rear side of the refrigerated storage chamber 1, and the cooling area is preferably located in the upper half of the height direction of the refrigerated storage chamber 1, that is, the cooling area is preferably located above the middle height plane of the refrigerated storage chamber 1, and the cooling area extends along the length direction of the refrigerated storage chamber 1. The length and the positions of the left and right ends of the cooling area can be set according to the specific conditions inside the refrigerated storage chamber 1, as close to the refrigerated storage chamber as possible. The left and right sides of the storage chamber 1; the cooling pipe assembly 4 includes several cooling pipes, which are used to pass refrigerant. The cooling pipe assembly 4 is arranged in the cooling area, and the cooling pipe assembly 4 extends from the left side to the right side of the cooling area along the length direction, that is, there are cooling pipes at different positions in the length direction of the cooling area. There can be an appropriate distance between the cooling pipe assembly 4 and the rear side of the refrigerated storage chamber 1, or it can be directly fixed on the rear side of the refrigerated storage chamber 1; there are one or more fans 2, and when there are multiple fans, they are arranged along the length direction of the refrigerated storage chamber 1. The fan 2 is arranged next to the cooling pipe assembly 4, specifically, it can be arranged on the front or rear side of the cooling pipe assembly 4, and an appropriate distance is maintained between the two. The fan 2 can blow air forward, so that the gas at the cooling pipe assembly 4 can flow to the front side of the refrigerated storage chamber 1.

[0041] The main working principle of the rear-vent type refrigerator of the present invention is as follows: when multiple items are placed in the refrigerated storage chamber 1, the items are arranged along the length of the refrigerated storage chamber 1, with appropriate spacing between the items in the length direction according to actual conditions. During operation, a refrigerant is introduced into the cooling tube assembly 4. The refrigerant can be a fluid capable of refrigeration, such as air, Freon, or water. The cooling tube assembly 4 cools the gas near it through heat exchange to form cold gas. The fan 2 rotates to blow the cold gas out of the air outlet in the cover 3 and toward the front side of the refrigerated storage chamber 1. When the cold gas flows forward and hits the front side of the refrigerated storage chamber 1, it sinks downward, thereby forming a circular airflow in the refrigerated storage chamber 1. The circulating cooling effect is better when the cooling tube assembly 4 and the fan 2 are both located in the upper half of the height direction of the refrigerated storage chamber 1. The fan 2 provides power for the circulating flow of the cold gas. Since the cooling pipe assembly 4 and the fan 2 are both arranged along the length direction (i.e., the left and right direction) of the refrigerated storage chamber 1, it is possible to cool down various positions in the length direction, and the cold gas can pass through the spacing spaces between the objects when circulating, reducing the impact of obstruction caused by objects, achieving uniform cooling of various locations in the refrigerated storage chamber 1, and ensuring the refrigeration effect of the objects.

[0042] See also Figures 1 to 6 The present invention is further described below with a specific embodiment:

[0043] In this embodiment, see Figure 1 As a preferred design, the refrigerated storage compartment 1 further includes a housing 3 that encloses the cooling tube assembly 4 and the fan 2. The housing 3 is provided with an air outlet for the fan 2 to blow air outward. When the fan 2 rotates, the cold air is blown out of the air outlet in the housing 3 toward the front of the refrigerated storage compartment 1. The housing 3 protects the cooling tube assembly 4 and the fan 2, and reduces the natural expansion of the cold air near the cooling tube assembly 4 within the housing 3, allowing the cold air to be blown out as much as possible through the fan 2, thus achieving a cold air circulation.

[0044] In this embodiment, see Figure 1 and Figure 6 As a preferred design, fan 2 is directly fixed to housing 3 and located in front of cooling tube assembly 4. In this case, the blades of fan 2 are located in the air outlet of housing 3, better blowing the cold air out of the air outlet. The number of fans 2 can be set according to actual needs. Adjacent fans 2 can be appropriately spaced along the length of refrigerated storage compartment 1 or placed side by side.

[0045] In this embodiment, see Figure 1 As a preferred design, the cooling tube assembly 4 includes a single curved cooling tube to reduce the number of openings on the sidewall of the refrigerated storage chamber 1. The cooling tube includes multiple straight tube sections extending in a straight line along the length of the refrigerated storage chamber 1, as well as connecting curved tube sections that connect adjacent straight tube sections to ensure effective cooling. The cooling tube may also be curved in other ways, for example, the straight tube sections may extend up and down or at an angle. In another embodiment, the cooling tube assembly 4 may include multiple independent cooling tubes, each of which extends in a straight line along the length of the refrigerated storage chamber 1.

[0046] In this embodiment, see Figure 1 As a preferred design, the fans 2 are arranged at equal intervals along the length direction of the refrigerated storage chamber 1. The specific number of fans 2 can be set according to actual needs, and the leftmost and rightmost fans 2 are preferably close to the left and right sides of the cooling area respectively to better achieve the cooling effect.

[0047] In this embodiment, see Figure 1 As a preferred design, the system also includes a refrigerant supply device 5, which is connected to the cooling pipe and can supply refrigerant to the cooling pipe. The refrigerant supply device 5 uses a circulating supply method, where the refrigerant exiting the cooling pipe returns to the refrigerant supply device 5, is cooled, and then re-introduced into the cooling pipe, thus forming a circulating operation. The refrigerant supply device 5 is located on the left or right side of the refrigerated storage compartment 1 so as not to affect staff members from accessing items in the refrigerated storage compartment 1 from the front of the refrigerator.

[0048] In this embodiment, as a preferred design, multiple storage containers (not shown in the drawings) are further provided within the refrigerated storage compartment 1. The storage containers are arranged along the length of the refrigerated storage compartment 1 and are preferably spaced appropriately apart in the lengthwise direction. The spacing is determined based on actual needs. The storage containers can store liquids such as tea, as well as other solid items.

[0049] In this embodiment, see Figure 3 and Figure 4 As a preferred design, the refrigerated storage compartment 1 further includes a tiered shelf 6 and a support assembly. The support assembly is fixedly mounted on the side wall of the refrigerated storage compartment 1, and the edges of the tiered shelf 6 are placed on the support assembly. When items need to be layered in the refrigerated storage compartment 1, one or more layers of the tiered shelf 6 can be placed in the refrigerated storage compartment 1. When tiered placement is no longer required, the tiered shelf 6 can be removed, providing flexibility and convenience.

[0050] In this embodiment, see Figure 1 As a preferred design, the support assembly includes a vertical frame 7 and a support frame 8. The vertical frame 7 is fixed to the side wall of the refrigerated storage chamber 1 and is provided with multiple insertion holes 71 along the height direction. The support frame 8 is detachably inserted into the insertion holes 71. The edge of the layered storage rack 6 is placed on the support frame 8. As needed, the support frame 8 can be inserted into the insertion holes 71 at different heights of the vertical frame 7, thereby adjusting the height position of the layered storage rack 6, which is flexible and convenient to use. Furthermore, the support frame 8 includes a support plate 81 and a diagonal support plate 82. The diagonal support plate 82 is fixedly connected to the support plate 81 and supports the support plate 81 from the bottom. The support plate 81 and the diagonal support plate 82 are both inserted into the insertion holes 71. The edge of the layered storage rack 6 is placed on the support plate 81, and the bottom side of the support plate 81 is supported by the diagonal support plate 82, which has good stability and is easy to install. Preferably, a stopper plate 83 is further provided on the support plate 81, and stopper holes are provided near the edges of the tiered storage rack 6. When the edge of the tiered storage rack 6 is placed on the support plate 81, the stopper plate 83 is inserted into the stopper hole of the tiered storage rack 6, thereby preventing the tiered storage rack 6 from falling off the support plate 81. The tiered storage rack 6 can have a mesh structure, in which case the mesh holes at its edges constitute the stopper holes.
