[0044] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0045] This disclosure provides a temperature-changing device for refrigeration equipment, such as... Figures 1 to 9 As shown, the temperature-changing device for refrigeration equipment includes a first housing 100, a first plate 200, and a second plate 300. The first housing 100 has a temperature-changing chamber 101 and a first air inlet 102, a second air inlet 103, and an air outlet 104 communicating with the temperature-changing chamber 101. The first air inlet 102 can communicate with the refrigeration air duct of the refrigeration equipment, the second air inlet 103 can be connected to the outside, and the air outlet 104 can be connected to the outside. The first plate 200 is located outside the temperature-changing chamber 101 and can move between a first position with the opening of the temperature-changing chamber 101 open and a second position with the opening of the temperature-changing chamber 101 closed. The second plate 300 is disposed inside the temperature-controlled chamber 101. The second plate 300 is used to place items. The second plate 300 can move between the opening of the temperature-controlled chamber 101 and the end of the temperature-controlled chamber 101 away from the opening, so as to close the opening of the temperature-controlled chamber 101 and move the items out of the temperature-controlled chamber 101, or open the opening of the temperature-controlled chamber 101 and move the items into the temperature-controlled chamber 101.

[0046] With the optional embodiment, the second plate body 300 can be used to place the articles, and move between the opening of the temperature-variable chamber 101 and the end of the temperature-variable chamber 101 away from the opening, when the second plate body 300 is located at the opening of the temperature-variable chamber 101, the second plate body 300 can close the temperature-variable chamber 101, and the articles are located outside the temperature-variable chamber 101. At this time, when the articles are placed on the second plate body 300, the first plate body 200 can be arranged in the second position to reduce the occurrence of the second plate body 300 hindering the articles from moving out of the temperature-variable chamber 101. When the second plate body 300 is located at the end of the temperature-variable chamber 101 away from the opening, the second plate body 300 opens the temperature-variable chamber 101, and the articles are located inside the temperature-variable chamber 101, at this time, the first plate body 200 can be arranged in the first position to make the first plate body 200 close the temperature-variable chamber 101.

[0047] The first cabinet 100 is configured with the temperature-variable chamber 101, the first air inlet 102, the second air inlet 103 and the air outlet 104 are all communicated with the temperature-variable chamber 101, and the first air inlet 102 can be communicated with the refrigeration air duct of the refrigeration equipment, and the second air inlet 103 can be communicated with the outside. In this way, when the first air inlet 102 is communicated with the refrigeration air duct of the refrigeration equipment, the cold air in the refrigeration air duct can enter the temperature-variable chamber 101 through the first air inlet 102 to cool the temperature-variable chamber 101, so as to cool the articles stored in the temperature-variable chamber 101. When the second air inlet 103 and the air outlet 104 are both communicated with the outside, the room temperature air outside can enter the temperature-variable chamber 101 through the second air inlet 103, and flow out of the temperature-variable chamber 101 from the air outlet 104, so that the temperature in the temperature-variable chamber 101 can be the same as the room temperature.

[0048] In this embodiment, when it is necessary to store the articles by refrigeration and freezing, the articles can be first placed in the temperature-variable chamber 101 with the same temperature as the room temperature, the temperature difference between the inside and outside of the articles is small, and the generation of condensed water in the packaging box or the packaging bag can be reduced. After the articles are placed in the temperature-variable chamber 101, cold air is supplied to the temperature-variable chamber 101 through the first air inlet 102 to synchronize the temperature-variable chamber 101 and the articles, so as to reduce the temperature difference between the inside and outside of the articles, increase the time required for the cooling of the articles, and slowly cool the articles, so that the condensation process is relatively stable, thereby reducing the amount of condensed water generated in the articles and improving the preservation effect of the articles. In this embodiment, the articles are placed on the second plate body 300, which can be moved into and out of the temperature-variable chamber 101, so as to facilitate the user to place and take the articles and improve the user experience.

[0049] Figures 1 to 4 The structure diagram of the first plate body 200 in the first position and the second plate body 300 closing the opening of the temperature-variable chamber 101 in this embodiment.

[0050] Figure 5 and Figure 6 This is a schematic diagram of the structure in this embodiment where the first plate 200 is in the second position and the second plate 300 opens the opening of the variable temperature chamber 101.

[0051] In some alternative embodiments, the temperature-changing device for the refrigeration equipment further includes a first damper and a second damper. The first damper is located at the first air inlet 102 and is used to close or open the first air inlet 102. The second damper is located at the second air inlet 103 and is used to close or open the second air inlet 103.

[0052] Among them, such as Figures 1 to 4 As shown, when the first plate 200 is in the first position, the second plate 300 closes the opening of the temperature-controlled chamber 101, the first damper closes the first air inlet 102, and the second damper opens the second air inlet 103.

[0053] like Figure 5 and Figure 6 As shown, when the first plate 200 is in the second position, the second plate 300 is located at the end of the variable temperature chamber 101 away from the outlet, the first damper opens the first air inlet 102, and the second damper closes the second air inlet 103.

[0054] In this embodiment, the first damper can close or open the first air inlet 102, and the second damper can close or open the second air inlet 103, so as to control the entry of air of different temperatures into the variable temperature chamber 101, thereby lowering or increasing the temperature of the variable temperature chamber.

[0055] With the first plate 200 in the second position, i.e., the first plate 200 closes the opening of the variable temperature chamber 101. At this time, the second plate 300 is located at the end of the variable temperature chamber 101 away from the opening, and the second plate 300 moves the item into the variable temperature chamber 101. The first damper opens the first air inlet 102, and the second damper closes the second air inlet 103. In this way, the cold air from the refrigeration duct of the refrigeration equipment can enter the variable temperature chamber 101 through the first air inlet 102 to cool the variable temperature chamber 101 and the item inside the variable temperature chamber 101, reduce the temperature difference between the inside and outside of the item, and thus reduce the occurrence of a large amount of condensation due to the large temperature difference between the inside and outside of the item.

[0056] Optionally, when the item is food with a box or bag, the user can open the box or bag while placing the food on the second plate 300. This allows water vapor from the box or bag to flow into the temperature-controlled chamber 101 during the slow cooling process, further reducing condensation and improving food preservation.

[0057] And, at this time, the first plate body 200 closes the opening of the temperature-variable chamber 101, so that the temperature-variable chamber 101 is an independent space, and the cold air in the refrigeration space of the refrigeration device is reduced to enter the temperature-variable chamber 101 through the opening of the temperature-variable chamber 101, so that the cold quantity in the temperature-variable chamber 101 is controllable, the control accuracy of the temperature of the temperature-variable chamber is improved, and the use experience of the user is improved.

[0058] In the case where the first plate body 200 is located at the first position, that is, the first plate body 200 opens the opening of the temperature-variable chamber 101, at this time, the second plate body 300 closes the opening of the temperature-variable chamber 101, the second plate body 300 is located at the opening of the temperature-variable chamber 101, the article is placed on the second plate body 300, the article is located outside the temperature-variable chamber 101, and the article is in the refrigeration space of the refrigeration device. The refrigeration chamber continues to refrigerate or freeze the article at a reduced temperature, so as to reduce the case that a large amount of condensed water is generated in the article due to a high temperature difference between the inside and outside after the normal temperature or high temperature article is directly placed in the refrigeration chamber, and improve the preservation effect of the article. And, at this time, the first air door closes the first air inlet 102, and the second air door opens the second air inlet 103. In this way, the room temperature normal temperature air can enter the temperature-variable chamber 101 through the second air inlet 103, so as to increase the temperature of the temperature-variable chamber, so that the temperature in the temperature-variable chamber 101 is the same as the room temperature, so as to prepare for the next pre-refrigeration or freezing of the article. The second plate body 300 is located at the opening of the temperature-variable chamber 101, and the second plate body 300 can close the opening of the temperature-variable chamber 101, so as to reduce the flow of normal temperature air in the temperature-variable chamber 101 into the refrigeration space of the refrigeration device through the opening of the temperature-variable chamber 101, and improve the refrigeration or freezing effect of the refrigeration device.

[0059] Optionally, the opening of the temperature-variable chamber 101 is located on the side wall of the temperature-variable chamber 101, the second plate body 300 comprises a first sub-plate body and a second sub-plate body connected with each other, there is an angle between the first sub-plate body and the second sub-plate body, the first sub-plate body is vertically arranged to close or open the opening of the temperature-variable chamber 101, and the second sub-plate body is horizontally arranged to place the article.

[0060] Optionally, the air outlet 104 can also communicate with the refrigeration air duct of the refrigeration device. Optionally, the temperature-variable device for the refrigeration device further comprises a three-way pipe, a first end of the three-way pipe communicates with the air outlet 104, a second end of the three-way pipe is connected with the outside, and a third end of the three-way pipe communicates with the refrigeration air duct.

[0061] In the case where the first air door opens the first air inlet 102, the air outlet 104 communicates with the refrigeration air duct, that is, the first end of the three-way pipe communicates with the third end of the three-way pipe. In this way, the cold air entering the temperature-variable chamber 101 from the first air inlet 102 can flow back into the refrigeration air duct through the air outlet 104 again, so that the cold air can circulate and flow, and the pressure in the temperature-variable chamber 101 is reduced.

[0062] When the second damper opens the second air inlet 103, the air outlet 104 is in communication with the outside, i.e., the first end of the tee pipe is in communication with the second end of the tee pipe. In this way, the normal-temperature air entering the temperature-variable chamber 101 from the second air inlet 103 can flow back to the outside through the air outlet 104 to take away the cold energy of the temperature-variable chamber 101, thereby increasing the temperature in the temperature-variable chamber 101.

[0063] In some optional embodiments, as shown in Figure 3 、 Figure 4 and Figure 7 , the opening of the temperature-variable chamber 101 is located at the top wall of the temperature-variable chamber 101, and the end of the temperature-variable chamber 101 away from the opening is the bottom of the temperature-variable chamber 101. The temperature-variable device for the refrigeration equipment further comprises a first driving assembly 310, which is arranged in the temperature-variable chamber 101 and connected with the second plate body 300 to drive the second plate body 300 to move up and down between the opening of the temperature-variable chamber 101 and the bottom of the temperature-variable chamber 101.

[0064] In this embodiment, the first driving assembly 310 is arranged in the temperature-variable chamber 101 and connected with the second plate body 300, so that the first driving assembly 310 can drive the second plate body 300 and the articles placed on the second plate body 300 to move between the opening of the temperature-variable chamber 101 and the bottom of the temperature-variable chamber 101, thereby opening or closing the opening of the temperature-variable chamber 101 and moving the articles on the second plate body 300 into or out of the temperature-variable chamber 101, which is convenient for users to operate and improves the user experience.

[0065] Exemplarily, as shown in Figure 3 、 Figure 4 and Figure 8 , the first driving assembly 310 comprises a fork rod assembly 311 and an electric telescopic rod 312, one end of the fork rod assembly 311 is connected with the bottom wall of the temperature-variable chamber 101, and the other end of the fork rod assembly 311 is connected with the second plate body 300.

[0066] With the optional embodiment, the fork rod set 311 comprises a first fork rod 3111 and a second fork rod 3112 which are crossly hinged and can be turned to adjust the distance between the two ends of the fork rod set 311. The two ends of the fork rod set 311 are connected with the bottom wall of the temperature-variable chamber 101 and the second plate body 300 respectively, so as to adjust the distance between the second plate body 300 and the bottom wall of the temperature-variable chamber 101, and enable the second plate body 300 to move relative to the bottom wall of the temperature-variable chamber 101 to the opening of the temperature-variable chamber 101 or the bottom of the temperature-variable chamber 101.

[0068] Optionally, the electric telescopic rod 312 is hingedly connected with the first fork rod 3111, or the electric telescopic rod 312 is hingedly connected with the second fork rod 3112. When the electric telescopic rod 312 is extended, the electric telescopic rod 312 drives the other end of the first fork rod 3111 and the other end of the second fork rod 3112 to move in a direction away from the bottom wall of the temperature-variable chamber 101, so as to close the opening of the temperature-variable chamber 101 and move the articles placed on the second plate body 300 out of the temperature-variable chamber 101. When the electric telescopic rod 312 is retracted, the electric telescopic rod 312 drives the other end of the first fork rod 3111 and the other end of the second fork rod 3112 to move towards the bottom wall of the temperature-variable chamber 101, so as to open the opening of the temperature-variable chamber 101 and move the articles on the second plate body 300 into the temperature-variable chamber 101.

One end of the second fork of the first fork group is connected to the bottom wall of the temperature-changing chamber 101, and the other end of the second fork of the first fork group is connected to one end of the second fork of the second fork group. The other end of the second fork of the second fork group is connected to the second plate 300.

[0072] In some alternative embodiments, such as Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 9 As shown, the temperature-changing device for the refrigeration equipment also includes a second drive assembly 210. The first housing 100 is disposed at one end of the refrigeration space of the refrigeration equipment. One end of the second drive assembly 210 is connected to the first housing 100 at the opening of the temperature-changing chamber 101. The other end of the second drive assembly 210 extends to the other end of the refrigeration space. The first plate 200 is connected to the second drive assembly 210. The second drive assembly 210 drives the first plate 200 to move horizontally between the first position and the second position.

[0073] In this optional embodiment, the first housing 100 is located at one end of the refrigeration space, and the other end of the second drive assembly 210 extends to the other end of the refrigeration space. The first plate 200 is connected to the second drive assembly 210. That is, when the first plate 200 is in the second position, it is located at the other end of the refrigeration space, thus opening the opening of the variable temperature chamber 101. The second drive assembly 210 is connected to the first plate 200, and drives the first plate 200 to move between the first and second positions, thereby automating the movement of the first plate 200, facilitating operation, and improving the user experience.

[0074] For example, the second drive assembly 210 includes a drive motor 211, a synchronous pulley set 212, and a synchronous belt 213. The drive motor 211 is connected to the first housing 100 at the opening of the variable temperature chamber 101. The synchronous pulley set 212 includes a driving pulley 2121 and a driven pulley 2122. The driving pulley 2121 is connected to the drive motor 211, and the driven pulley 2122 is located on one side of the housing facing the other end of the cooling space.

[0075] The two ends of the timing belt 213 are connected to the driving pulley 2121 and the driven pulley 2122 respectively. The first plate 200 is connected to the timing belt 213, and the timing belt 213 can drive the first plate 200 to move.

[0076] In the embodiment, the driving motor 211 is connected with the driving wheel 2121, and the driving motor 211 drives the driving wheel 2121 to rotate. The two ends of the synchronous belt 213 are connected with the driving wheel 2121 and the driven wheel 2122 respectively, and the driving wheel 2121 rotates the synchronous belt 213 to rotate around the driving wheel 2121 and the driven wheel 2122. The first plate body 200 is connected with the synchronous belt 213, so that the synchronous belt 213 drives the first plate body 200 to move between the first position and the second position, to open or close the opening of the temperature-variable chamber 101.

[0077] Optionally, the second driving assembly 210 further comprises a first support, and the driving motor 211 is connected with the first box body 100 at the opening of the temperature-variable chamber 101 through the first support, to fix the driving motor 211.

[0078] Optionally, the second driving assembly 210 further comprises a second support, and the driving wheel 2121 and / or the driven wheel 2122 are connected with the first box body 100 through the second support, to fix the driving wheel 2121 and / or the driven wheel 2122.

[0079] In the embodiment, the specific structure and setting mode of the first support and the second support can be set by the person skilled in the art according to the actual setting condition of the temperature-variable device for the refrigeration equipment, which is not limited here.

[0080] Optionally, as shown in Figure 9 Optionally, the driving wheel 2121 and the driven wheel 2122 are gears respectively, and the synchronous belt 213 is provided with teeth, and the synchronous belt 213 is engaged with the driving wheel 2121 and the driven wheel 2122 respectively.

[0081] Optionally, the temperature-variable device for the refrigeration equipment further comprises a second box body 500, the second box body 500 is connected with the first box body 100, and the second box body 500 is located on one side of the other end of the first box body 100 facing the refrigeration space, the second box body 500 defines a storage space 510, the second driving assembly 210 extends to the second box body 500, and the first plate body 200 can open or close the opening of the storage space 510.

[0082] In the embodiment, the second box body 500 is connected with the first box body 100, and the second box body 500 is provided with the storage space 510, to increase the storage capacity of the temperature-variable device for the refrigeration equipment, and improve the user experience. The second box body 500 is located on one side of the other end of the first box body 100 facing the refrigeration space, the second driving assembly 210 extends to the second box body 500, and the first plate body 200 can open or close the opening of the storage space 510. That is, when the first plate body 200 is in the first position, the first plate body 200 can close the opening of the storage space 510, and when the first plate body 200 is in the second position, the first plate body 200 can open the opening of the storage space 510.

[0083] Optionally, the second enclosure 500 is provided with ventilation holes, and the storage space 510 is connected to the refrigeration space through the ventilation holes. In this way, whether the first enclosure 200 is open or closed, the temperature inside the storage space 510 can be the same as the temperature of the refrigeration space of the refrigeration equipment. This increases the storage capacity of the variable temperature device used in the refrigeration equipment, improves the refrigeration or freezing effect of items placed in the storage space 510, and enhances the user experience.

[0084] In some alternative embodiments, the temperature-changing device for the refrigeration equipment further includes a pressure-sensing component and a controller (hereinafter referred to as the first controller for easy distinction), wherein the pressure-sensing component is disposed on the second plate 300 and is used to detect the bearing pressure of the second plate 300.

[0085] The pressure sensing component, the first drive component 310, and the second drive component 210 are respectively connected to the first controller. The first controller is used to receive the bearing pressure and control the first drive component 310 and the second drive component 210 to work according to the magnitude of the bearing pressure, so as to drive the first plate 200 to close the opening of the temperature-changing chamber 101, and / or the second plate 300 to open the opening of the temperature-changing chamber 101.

[0086] In this optional embodiment, the pressure sensing component, the first drive component 310, and the second drive component 210 are respectively connected to the first controller. The pressure sensing component is disposed on the second plate 300 and is used to detect the bearing pressure of the second plate 300. The pressure sensing component can transmit the bearing pressure to the first controller. The first controller can control the first drive component 310 and the second drive component 210 to work according to the received bearing pressure, so as to drive the first plate 200 to close the opening of the temperature-changing chamber 101, and the second plate 300 to open the opening of the temperature-changing chamber 101, so that the item placed on the second plate 300 can be moved into the temperature-changing chamber 101.

[0087] At this time, the first damper opens the first air inlet 102, and the second damper closes the second air inlet 103. In this way, the cold air in the refrigeration duct can gradually enter the variable temperature chamber 101 through the first air inlet 102 to cool the variable temperature chamber 101 and the items inside. This reduces the temperature difference between the inside and outside of the items during the cooling process, thereby reducing the occurrence of condensation inside the items, improving the preservation effect of the items, and enhancing the user experience.

[0088] Optionally, when the bearing pressure is greater than or equal to the preset pressure, the first controller controls the first drive assembly 310 to move the second plate 300 from the opening of the temperature-changing chamber 101 to the bottom of the temperature-changing chamber 101, and controls the second drive assembly 210 to move the first plate 200 from the first position to the second position.

[0089] The preset pressure can be the minimum pressure that the second plate 300 experiences when an item is placed on it.

[0090] When an item is detected on the second plate 300, the first drive assembly 310 moves the second plate 300 to the bottom of the temperature-controlled chamber 101 to place the item inside. The second drive assembly 210 then moves the first plate 200 from a first position to a second position to seal the temperature-controlled chamber 101. This allows for individual pre-cooling of items at room temperature or higher temperatures, reducing the occurrence of condensation due to large temperature differences between the inside and outside of the item, and improving the preservation effect.

[0091] In some alternative embodiments, such as Figure 7 As shown, the temperature-changing device for refrigeration equipment also includes a temperature sensing component 400 and a controller (hereinafter referred to as the second controller for easy distinction). The temperature sensing component 400 is located inside the temperature-changing chamber 101 and is used to detect the temperature of the temperature-changing chamber.

[0092] Temperature sensing component 400, first drive component 310 and second drive component 210 are respectively connected to second controller. The second controller is used to receive the temperature of the variable temperature chamber and, according to the relationship between the temperature of the variable temperature chamber and the temperature of the cooling space, control the first drive component 310 and the second drive component 210 to work so as to drive the first plate 200 to open the opening of the variable temperature chamber 101, and / or, the second plate 300 to close the opening of the variable temperature chamber 101.

[0093] In this optional embodiment, the temperature sensing component 400, the first drive component 310, and the second drive component 210 are respectively connected to the second controller. The temperature sensing component 400 is capable of receiving the temperature of the variable temperature chamber and transmitting the temperature of the variable temperature chamber to the second controller.

[0094] The second controller, based on the relationship between the temperature of the variable-temperature chamber and the temperature of the refrigerated space, controls the operation of the first drive assembly 310 and the second drive assembly 210. The second drive assembly 210 moves the first plate 200 from the second position to the first position to open the opening of the variable-temperature chamber 101. The first drive assembly 310 moves the second plate 300 from the bottom of the variable-temperature chamber 101 to the opening of the variable-temperature chamber 101 to remove items from the variable-temperature chamber 101, allowing the pre-cooled items to be stored in the refrigerated space and easily retrieved by the user.

[0095] At this time, the first damper closes the first air inlet 102, and the second damper opens the second air inlet 103. In this way, ambient outdoor air can enter the variable temperature chamber 101 to increase the temperature of the variable temperature chamber, prepare for the next pre-cooling of items, and improve the user experience.

[0096] Optionally, when the temperature of the variable temperature chamber is less than or equal to the temperature of the refrigeration equipment, the controller controls the second drive assembly 210 to move the first plate 200 from the second position to the first position to open the opening of the variable temperature chamber 101, and the first drive assembly 310 moves to the opening of the variable temperature chamber 101.

[0097] It should be noted that when the temperature-changing device used for refrigeration equipment includes both a temperature sensing component 400 and a pressure sensing component, the second controller in this embodiment can be the same controller as the first controller in the above embodiment, that is, the temperature sensing component 400, the pressure sensing component, the first drive component 310 and the second drive component 210 are respectively connected to the same controller.

[0098] In some alternative embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the temperature-changing device for refrigeration equipment also includes a sealing element 600, which surrounds the side wall of the opening of the temperature-changing chamber 101. The first plate 200 can be connected to one wall of the sealing element 600, and the second plate 300 can be connected to the other wall of the sealing element 600.

[0099] In this embodiment, the first plate 200 and the second plate 300 can selectively close the opening of the variable temperature chamber 101. The first plate 200 is located outside the variable temperature chamber 101, and the second plate 300 is located inside the variable temperature chamber 101. The sealing member 600 surrounds the side wall at the opening of the variable temperature chamber 101. When the first plate 200 closes the opening of the variable temperature chamber 101, the first plate 200 can connect with one wall surface of the sealing member 600. One wall surface of the sealing member 600 can be the wall surface of the sealing member 600 away from the bottom wall of the variable temperature chamber 101, so as to increase the sealing performance of the first plate 200 on the variable temperature chamber 101, reduce the occurrence of heat exchange between the variable temperature chamber 101 and the cooling space, and improve the temperature controllability of the variable temperature chamber.

[0100] When the second plate 300 closes the opening of the variable temperature chamber 101, the first plate 200 can connect with the other wall of the seal 600. The other wall of the seal 600 can be the wall of the seal 600 facing the bottom wall of the variable temperature chamber 101, so as to increase the sealing of the second plate 300 to the variable temperature chamber 101, reduce the occurrence of heat exchange between the variable temperature chamber 101 and the refrigeration space, and improve the refrigeration efficiency of the refrigeration space.
