Detailed Description

The embodiments of the present invention will be further explained with reference to the drawings.

As shown in fig. 1 and 2, in the embodiment of the refrigeration system and the refrigerated storage cabinet for storing fresh goods of the present invention, the refrigeration system and the refrigerated storage cabinet are illustrated as an example of a refrigerated storage cabinet for storing fresh goods in which the refrigeration system is installed. In the present embodiment, a refrigeration system is constructed based on a locker, and includes a compression unit 1, a condensation unit 2, and an evaporation unit 3; the evaporation unit 3 is arranged in a closed space 9 enclosed by a partition plate, in particular in a space for storing articles in the storage cabinet; the compression unit 1 is connected with the condensation unit 2 and arranged at the top of the storage cabinet, and the space where the compression unit is arranged is isolated from the space where the evaporation unit 3 is arranged; the evaporation unit 3 is connected with the condensation unit 2 through a controlled channel switch to form a cooling circuit for cooling the air in the closed space where the evaporation unit 3 is located; one or more article placement units 5 are provided in the enclosed space 9 in which the evaporation unit 3 is located. The case shown in fig. 1 is that two independent article placing units 5 are provided in one closed space 9, and it is actually possible to place one article placing unit 5, and the only difference between the two is that the path of the air flow in the closed space 9 may be different. The article placing unit 5 is embedded in the closed space except for one surface thereof; the evaporation unit 3 allows the article placing unit 5 to maintain a set temperature by exchanging heat with air in which the article placing unit 5 is embedded between the surface of the enclosed space 9 and the partition plates (i.e., the side panels, front and rear panels, and top and bottom plates of the locker) of the enclosed space 9.

In other words, in the present embodiment, the components of the refrigeration system are separated and not installed in the same space, and these components are connected together by a pipeline and a controlled pipeline switch (not shown in the figure), wherein the evaporation unit 3 is arranged in the closed space 9 to be cooled. The space is the space for placing articles in the storage cabinet; meanwhile, in the present embodiment, the conventional arrangement of the cabinet of the storage cabinet is abandoned, and all the storage spaces in the cabinet or the space are embedded into the enclosed space 9 (i.e. the space formed by the cabinet body of the storage cabinet) as a whole or as a plurality of whole (as two whole cases are shown in fig. 1), so that there is a certain distance between the storage space as a whole (i.e. the article placing unit 5) and the partition plate between the enclosed space 9 and the outside, and the space formed by the distance holds a certain amount of air, and when the air is cooled, the metal article placing unit 5 and the interior of the article placing unit 5 are also cooled due to heat transfer. Thereby, temperature maintenance in the article placing unit 5 is achieved. Meanwhile, due to this structure, it is also possible to use the above-mentioned space (i.e., the space between the article placing unit 5 and the partition of the cabinet) as a passage, so that air or air flow moves in the passage, thereby further enhancing the cooling effect. In fig. 1 to 3, the moving direction or path of the above-described air flow is indicated by an arrow icon.

Specifically, in the present embodiment, the article placing unit 5 is integrally fitted into the closed space from the front surface of the closed space, and the remaining surfaces of the article placing unit 5 are located within the closed space at a set distance from the respective partition plates forming the closed space, except for the front surface of the article placing unit 5. For example, there may be a set distance between the back of the article placing unit 5 and the back partition of the closed space, and between the left side plate of the article placing unit 5 and the left side plate of the closed space 9, and the distance between the side plate in each direction and the side plate of the corresponding side of the closed space may be different.

In this embodiment, the article placing unit 5 is integrally fixed in the closed space by a mounting bracket (not shown in the figure) provided in the closed space or on a partition plate (i.e., a front panel of the locker) provided at the front of the closed space. The article placing unit 5 includes a plurality of adjacent storage spaces 51, the storage spaces 51 are provided with openings for articles to enter and exit only on the front surface thereof, and each opening of the storage space is provided with a door 52 and an electric lock (not shown) which are independent of each other. For example, an opening having a size equal to that of the assembled or assembled article placing unit 5 may be provided on the front surface of the closed space (i.e., the front surface of the cabinet body), a mounting frame having a strength-enhancing function may be provided on the periphery of the opening, and the article placing unit 5 may be inserted through the opening and fixed to the mounting frame by screws or rivets, thereby achieving the insertion and fixation of the article placing unit 5. Of course, in some cases, a support frame may be disposed inside the cabinet body of the storage cabinet to further stabilize the article placing unit 5.

Generally, in the conventional storage cabinet, one storage cabinet usually includes two rows of storage spaces overlapped, in this embodiment, the two rows of storage spaces may be respectively embedded into the cabinet as two bodies, but the same evaporation unit 3 is used for cooling, as shown in fig. 1; the two lines of overlapped storage spaces can be separated into two mutually independent closed spaces. In this case, the evaporation units 3 include at least two, the at least two evaporation units 3 being respectively disposed in different closed spaces 9 formed by the partition plate 8 and the cabinet body; so that the different enclosures 9 are arranged adjacent to each other with an installation space above (i.e. on top of) the cabinet for the compression unit 1 and the condensation unit 2; the condensation unit 2 and the evaporation unit are connected by a pipe passing through the enclosed space 9 and the partition of the installation space. Referring to FIG. 3, FIG. 3 shows a schematic front view of the refrigerated storage cabinet in this case.

In the present embodiment, the controlled passage switch, which includes a solenoid valve, may be installed at a corresponding position in the closed space or the installation space (such that the above-mentioned connection pipe is as short as possible), and the evaporation unit 3 is connected to the condensation unit through the solenoid valve and the pipe, respectively, which are controlled by separate control signals, such that the refrigerant in the condensation unit can be introduced into the evaporation unit. For example, into either of the enclosed space evaporation units but not into the other, or both.

In the present embodiment, as shown in fig. 1 and 2, the evaporation unit 3 includes an evaporator 31 and an evaporation fan 32, the evaporation unit 3 is disposed above the closed space 9, the evaporation fan 32 is disposed between the article placing unit 5 and the side wall of the closed space 9, and generates an air flow that accelerates the flow of air between the side edge of the article placing unit 5 and the side wall of the closed space 9, and the direction and path of the air flow are indicated by arrows in fig. 1 to 3. In other words, in the present embodiment, the distance between the article placing unit 5 and the partition plate of the closed space 9 is used as an air passage, and the air flow generated by the evaporation fan 32 can flow from the top to the bottom and then return from the bottom to the top from the other side, thereby achieving the air flow in the closed space. In some cases, if the speed of the air flow is considered to be insufficient, another fan for generating an air flow having a set direction may be provided midway in the passage, usually at the lower end of the closed space. The added fan can increase the flow of the airflow again on the basis of the original airflow, so that the airflow is circulated faster, and the heat exchange is faster.

For the controlled channel switch, the switch-on of the controlled channel switch enables heat exchange in the connected evaporation unit 3, so that the temperature in the closed space 9 where the evaporation unit 3 is located can be reduced or controlled in a set area; when the evaporator is not connected, the closed space 9 where the connected evaporation unit 3 is located has no heat exchange, and the temperature of the closed space does not drop; in this case, it is common that the enclosed space 9 does not contain any stored items, does not need to be cooled down, or that its temperature is already controlled at a set temperature. The control is automatically carried out, specifically, for a closed space 9 needing temperature control, whether the controlled channel switch needs to be switched on or not is judged by detecting a temperature sensor in the article placing unit 5 in the closed space; whether the temperature of one closed space 9 needs to be controlled or not can be judged by that all the storage spaces 51 are not provided with stored articles. When all of the storage spaces 51 in one of the closed spaces 9 are not filled with the articles, it is apparent that the closed space 9 does not need to be temperature-controlled. In the present embodiment, for each of the storage spaces 51 of one article placing unit 5, a temperature sensor 52 is provided, and the temperature sensors 52 respectively acquire temperature value data in the storage spaces 51 where the temperature sensors are located and transmit the temperature value data to a control unit (not shown in the figure). And the control unit outputs a control signal to a controlled pipeline switch connected with the evaporation unit 3 arranged in the closed space 9 according to the average value of the temperature value data returned by the plurality of temperature sensors in the closed space 9, so that the controlled pipeline switch is switched on or off.

The utility model discloses still relate to a cold-stored locker for depositing give birth to bright article, including refrigerating system, refrigerating system is foretell refrigerating system.
