Description

Technical Field

[0001] This application relates to the technical field of refrigeration equipment, for example, to a cold and hot cabinet. Background Art

[0002] Currently, existing single-compartment freezers or refrigerators can only function as a freezer or a refrigerator separately. In hot summers, such freezers or refrigerators can meet people's requirements for frozen foods or beverages. However, such freezers have a single function and cannot be heated. Especially in winter, they are usually put aside and used again after the weather gets warmer.

[0003] The cold and hot cabinets disclosed in the related art include a main heat insulation board, an auxiliary heat insulation board, and a heating module. Among them, the auxiliary heat insulation board is rotatably connected to the front edge of the main heat insulation board, and the heating module is fixed on the main heat insulation board and located on the first surface of the main heat insulation board. When simultaneous refrigeration and heating are required, the main heat insulation board and the auxiliary heat insulation board are flush, and the heating module will heat the heating cavity, while the refrigeration cavity maintains the refrigeration state using the refrigeration circuit; when heating is not required, the heating module can be turned off, and the auxiliary heat insulation board can be folded to connect the refrigeration cavity and the heating cavity.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0005] In the related art, when the heating module switches from the heating mode to the refrigeration mode, it is necessary to remove the items placed on the auxiliary heat insulation board and reposition them to other places. The operation is complex, resulting in an increase in the time for opening the door of the refrigerator, serious loss of cold / heat of the refrigerator, and excessive energy consumption.

[0006] It should be noted that the information disclosed in the above background art is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Invention

[0007] To have a basic understanding of some aspects of the disclosed embodiments, a simple summary is given below. This summary is not a general review, nor is it intended to identify key / important elements or delineate the protection scope of these embodiments, but rather serves as a preface to the subsequent detailed description.

[0008] The embodiments of the present disclosure provide a cold and hot cabinet to avoid the problem of energy loss caused by the disassembly of the partition and the repositioning of the items on the partition when switching between heating and refrigeration functions.

By controlling the second air damper assembly to open the second ventilation opening, the communication between the first chamber and the second chamber can be achieved, so that the air flow can circulate from the first chamber to the second chamber, thereby realizing the circulation of the air flow. By controlling the first air damper assembly to close the first ventilation opening, the blocking between the first air duct and the second air duct can be achieved.

[0052] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other.

[0053] Combined Figures 1 to 11 As shown, the embodiments of the present disclosure provide a cold and hot cabinet, including an inner container 100, a partition 200, a first air door assembly 300, and a second air door assembly 400. A storage cavity is defined inside the inner container 100; the partition 200 is arranged in the storage cavity to divide the storage cavity into a first chamber 110 and a second chamber 120 which are distributed up and down. The first chamber 110 has a first air duct 111 for refrigeration or heating, and the second chamber 120 has a second air duct 121 for refrigeration. Among them, the first side end 210 of the partition 200 is arranged between the first air duct 111 and the second air duct 121, and a first ventilation opening 510 is provided at the first side end 210 of the partition 200, and a second ventilation opening 520 is provided at the second side end 220 of the partition 200; the first air door assembly 300 is arranged at the first ventilation opening 510, and the first air door assembly 300 is used to open or block the first ventilation opening 510 to connect or block the first air duct 111 and the second air duct 121; the second air door assembly 400 is arranged at the second ventilation opening 520, and the second air door assembly 400 is used to open or block the second ventilation opening 520 to connect or block the first chamber 110 and the second chamber 120; when switching to refrigerate the first chamber 110, the first air door assembly 300 opens the first ventilation opening 510 to conduct the first air duct 111 and the second air duct 121, and the second air door assembly 400 opens the second ventilation opening 520 to connect the first chamber 110 and the second chamber 120; when switching to heat the first chamber 110, the first air door assembly 300 blocks the first ventilation opening 510, and the second air door assembly 400 blocks the second ventilation opening 520.

[0054] Optionally, a storage cavity for storing items is defined inside the inner container 100. A partition 200 is arranged in the storage cavity. The partition 200 can divide the storage cavity into a first chamber 110 and a second chamber 120 which are independent of each other. The first chamber 110 can be used for refrigeration or heating. A heating component is arranged in a first air duct 111 inside the first chamber 110. When the heating component operates, it is used to provide heat for the first chamber 110. The second chamber 120 is used for refrigeration. A refrigeration component is arranged in a second air duct 121 of the second chamber 120. The refrigeration component is used to provide cold for the second chamber 120 and the first chamber 110. Wherein, when the first air duct 111 and the second air duct 121 are communicated, the cold in the second air duct 121 can be transported to the first air duct 111, so as to refrigerate the first chamber 110. Optionally, the first chamber 110 is arranged above the second chamber 120. Since the refrigeration system of the refrigeration device usually includes devices such as a compressor, arranging the second chamber 120 below is convenient for arranging refrigeration components such as the compressor.

[0055] Optionally, a first side end 210 of the partition 200 is arranged between the first air duct 111 and the second air duct 121. A first ventilation opening 510 penetrating the partition 200 is arranged at the first side end, and a first air door assembly 300 is arranged at the first ventilation opening 510. At the same time, a second ventilation opening 520 is arranged at a second side end 220 of the partition 200, and a second air door assembly 400 is arranged at the second ventilation opening 520. When the first air door assembly 300 opens the first ventilation opening 510, the second air door assembly 400 opens the second ventilation opening 520. When the first air door assembly 300 blocks the first ventilation opening 510, the second air door assembly 400 blocks the second ventilation opening 520.

[0056] When the first air door assembly 300 opens the first ventilation opening 510, the communication between the first air duct 111 and the second air duct 121 can be realized. And when the second air door assembly 400 opens the second ventilation opening 520, the communication between the first chamber 110 and the second chamber 120 can be realized. In this way, the low-temperature air flow in the second air duct 121 can enter the first chamber 110 through the first air duct 111 to refrigerate the first chamber 110, and enter the second chamber 120 through the second ventilation opening 520 and further return to the second air duct 121, so as to realize the circulation of the air flow. In this way, the communication between the first air duct 111 and the second air duct 121 and the communication between the first chamber 110 and the second chamber 120 can be realized without moving the items placed on the partition 200, so that the low-temperature air flow circulates between the second air duct 121, the first air duct 111, the first chamber 110 and the second chamber 120. Furthermore, when switching to refrigerate the first chamber 110, the long-time opening of the cold and hot cabinet doors can be avoided, which is beneficial to reducing energy loss and energy consumption.

[0057] When the first air damper assembly 300 blocks the first ventilation opening 510, the communication between the first air duct 111 and the second air duct 121 can be blocked. And when the second air damper assembly 400 blocks the second ventilation opening 520, the communication between the first chamber 110 and the second chamber 120 can be blocked. In this way, the first chamber 110 can be heated independently, and at the same time, the second chamber 120 can be cooled independently, so as to realize the diversification of the functions of the cold and hot cabinet.

[0058] Optionally, the first ventilation opening 510 is arranged at one end of the back plate of the inner container 100 close to it and extends along the width of the partition plate 200 to ensure the flow area of the first ventilation opening 510.

[0059] Preferably, the second side end 220 is arranged opposite to the first side end 210. In this way, the low-temperature air flow flows into the first chamber 110 from one end of the back plate of the inner container 100 close to it and flows to the second chamber 120 from the end far away from the back plate. The flow path of the air flow can cover the partition plate 200, so as to improve the temperature uniformity in the first chamber 110 when the first chamber 110 is cooled. In addition, by arranging the first ventilation opening 510 and the second ventilation opening 520 at two opposite side ends respectively, the structural strength of the middle part of the partition plate 200 can be improved, and the safety and stability of the partition plate can be enhanced. At this time, the second ventilation opening 520 extends along the width direction of the partition plate 200.

[0060] Optionally, the second side end 220 can also be a side end adjacent to the first side end 210, or the second side end 220 can also be two side ends adjacent to the first side end 210. At this time, the second ventilation opening 520 extends longitudinally along the partition plate 200. It should be noted that the longitudinal direction mentioned here refers to the direction from the end of the partition plate 200 far away from the back plate of the inner container 100 to the end close to the back plate.

[0061] By using the hot and cold cabinet provided by the embodiment of the present disclosure, by controlling the first damper assembly to open the first vent, the first air duct and the second air duct can be connected, so that the low-temperature airflow in the second air duct can enter the first chamber through the first air duct to realize the refrigeration of the first chamber, and by opening the second vent by the second damper assembly, the first chamber and the second chamber can be connected, so that the airflow from the first chamber to the second chamber can be circulated to realize the circulation of the airflow. By controlling the first damper assembly to close the first vent, the first air duct and the second air duct can be blocked, and by controlling the second damper assembly to close the second vent, the first chamber and the second chamber of the air duct can be disconnected from each other, the first chamber is independently heated, and the second chamber is independently cooled, so as to realize the diversification of the storage function of the hot and cold cabinet. In this way, by switching the first damper assembly and the second damper assembly, the first chamber can be switched between the heating or cooling function without moving the partition, and the items stored on the partition do not need to be moved, so that the opening time of the door body can be reduced to reduce energy loss and reduce the energy consumption of the hot and cold cabinet.

[0062] Optionally, the first damper assembly 300 includes a cover plate 310 and a first drive motor 320. The cover plate 310 is constructed such that the cover plate profile can at least cover the first vent 510, the cover plate 310 is rotatably disposed on the first vent 510, and can at least be controlled to switch between an open state and a shielding state, the open state includes the cover plate 310 avoiding the first vent 510, and the shielding state includes the cover plate 310 blocking the first vent 510; the first output shaft of the first drive motor 320 is drivingly connected to the cover plate 310, and is used to drive the cover plate 310 to rotate around the output shaft in the first direction or the second direction, so that the cover plate 310 switches between the open state and the shielding state, wherein the first direction and the second direction have opposite rotation directions.

[0063] When the first chamber 110 is switched to cooling, the cover 310 is switched to an open state; when the first chamber 110 is switched to heating, the cover 310 is switched to a shielding state.

[0064] Optionally, the first vent 510 extends in the width direction of the partition 200, and the cover plate 310 is constructed to have a cover plate profile that can at least cover the first vent 510, so as to avoid air flow leaking from the second air duct 121 to the first air duct 111 when the cover plate 310 blocks the first vent 510, thereby avoiding affecting the heating effect of the first air duct 111 on the first chamber 110.

[0065] The first driving motor 320 is used to provide power for the cover plate 310. The extending direction of the first output shaft of the first driving motor 320 is the same as the length direction of the cover plate 310, so as to drive the cover plate 310 to rotate around the axis in its own length direction. Optionally, the first driving shaft of the first driving motor 320 is arranged on the side in the length direction, so that when the cover plate 310 is opened, it is located at the side end in the length direction of the first ventilation opening 510, so as to avoid blocking the air flow.

[0066] Optionally, the cover plate 310 includes a first plate body 311 and a second plate body 312 stacked up and down. The shape profile of the second plate body 312 is adapted to the shape profile of the first ventilation opening 510 and can be covered in the first ventilation opening 510; the periphery of the first plate body 311 extends out of the second plate body 312 to form a lapping portion 313. When the cover plate 310 blocks the first ventilation opening 510, the lapping portion 313 abuts against the periphery forming the first ventilation opening 510, and the second plate body 312 is covered in the first ventilation opening 510. In this way, the sealing effect of the cover plate 310 can be improved.

[0067] Optionally, a first magnetic attracting member is provided on the lapping portion 313 facing the periphery forming the first ventilation opening 510, and a second magnetic attracting member is provided on the periphery forming the first ventilation opening 510. The first magnetic attracting member and the second magnetic attracting member attract each other to improve the sealing performance when the cover plate 310 blocks the first ventilation opening 510.

[0068] Optionally, a connecting ventilation duct 122 is provided between the second air duct 121 and the first ventilation opening 510 to serve as an extended air duct of the second air duct 121. The first end of the connecting ventilation duct 122 is attached to the surface of the cover plate 220 facing the second chamber 120, and the opening of the first end of the connecting ventilation duct 122 is larger than the opening of the first ventilation opening 510 to avoid leakage of low-temperature air flow. Optionally, the first end of the connecting ventilation duct 122 extends out of the first ventilation opening 510 and extends into the first air duct 111, and the outer side wall of the connecting ventilation duct 122 abuts against the peripheral side wall of the first ventilation opening 511 to avoid leakage of the low-temperature air flow flowing from the second air duct 121 to the first air duct 111. Further, the first air damper assembly 300 is arranged at the first end of the connecting ventilation duct 122.

[0069] Optionally, the first ventilation opening 510 extends transversely, and a plurality of sub-ventilation openings 511 are arranged at intervals. Each sub-ventilation opening 511 is provided with a first air damper assembly 300.

[0070] By setting the first ventilation opening 510 as a plurality of spaced sub-ventilation openings 511, the air flow flowing from the second air duct 121 into the first air duct 111 can be dispersed, avoiding the air flow being too concentrated in the first air duct 111. Correspondingly, the connecting ventilation duct 122 includes sub-connecting ventilation ducts corresponding to the plurality of sub-ventilation openings 511.

[0071] Optionally, the refrigerator-freezer further includes a first air duct plate 610 and at least one partition rib 611. The first air duct plate 610 is disposed in the first chamber 110 and forms a first air duct 111 between the back plate of the inner container 100; the partition rib 611 is vertically disposed on the back plate of the inner container 100 and can divide the first air duct 111 into a plurality of independent sub-air ducts, and a heating component is disposed in one of the sub-air ducts; wherein, the sub-air ducts are in one-to-one correspondence with the sub-air vents 511, and a first air outlet 531 is provided on the first air duct plate 610 corresponding to each sub-air duct.

[0072] Optionally, a first blower is disposed in the sub-air duct provided with the heating component. When the first air door assembly 300 blocks the first air vent 510, the heating component and the first blower can be controlled to operate so as to heat the first chamber 110. Optionally, the sub-air duct provided with the heating component is the first sub-air duct 1111, and the remaining sub-air ducts are the second sub-air ducts 1112. The heating component and the first blower are disposed in the first sub-air duct 1111. When the first chamber 110 is heated, the air flow circulates between the first sub-air duct 1111 and the first chamber 110. When the first chamber 110 is cooled, the air flow flows into the first chamber 110 from the first sub-air duct 1111 and the second sub-air ducts 1112.

[0073] Correspondingly, the first air outlet 531 includes a first sub-air outlet 5311 and a second sub-air outlet 5312. The first sub-air outlet 5311 is communicated with the first sub-air duct 1111, and the second sub-air outlet 5312 is communicated with the second sub-air duct 1112.

[0074] Optionally, the first blower is disposed at the upper end of the first sub-air duct 1111, and the position of the upper end of the first air duct plate 610 corresponding to the first blower is the first air return port 532. The lower end of the first air duct plate 610 is the first sub-air outlet 5311, and the heating component is disposed between the first air return port 532 and the first sub-air outlet 5311. In this way, when the first chamber 110 is heated, it is beneficial for the high-temperature air flow to directly blow to the stored items, and the hot air flow has an upward flow trend, so that it is beneficial for the high-temperature air flow to circulate back to the first sub-air outlet 5311 to improve the heating effect. Optionally, the first sub-air outlet 5311 is provided at the position of the upper end of the first air duct plate 610 corresponding to the first blower, and the first air return port 532 is provided at the lower end of the first air duct plate 610. The high-temperature air flow flows out of the first sub-air duct 1111 from the first sub-air outlet 5311, and under the drive of the first blower, circulates in the first chamber 110 to the first air return port 532 and flows to the first sub-air outlet 5311 in the first sub-air duct 1111, thereby ensuring the circulation of the hot air flow.

[0075] Optionally, the partition ribs 611 include two, thus dividing the first air duct 111 into three sub-air ducts. Among them, the first sub-air duct 1111 is located in the middle, and the two second sub-air ducts 1112 are located on both sides of the first sub-air duct 1111. In this way, when cooling the first chamber 110, the low-temperature airflows enter the first sub-air duct 1111 and the second sub-air ducts 1112 respectively, and thus are divided into multiple strands. Part of the low-temperature airflow flows out from the first sub-air outlet 5311, and part of the low-temperature airflow flows out from the second sub-air outlet 5312, and then flows into the first chamber 110. In this way, by making the low-temperature airflow enter the first chamber 110 through multiple first air outlets 531, not only can the convergence of the low-temperature airflow be avoided and the air volume be increased, but also through the multiple first air outlets 531, the airflow can flow to multiple parts and multiple directions of the first chamber 110, so that the temperature uniformity in the first chamber 110 can be improved, and further the refrigeration effect of the low-temperature airflow can be enhanced.

[0076] Furthermore, a first fan is arranged in the first sub-air duct 1111, and the first fan can be operated when the first chamber 110 is cooled. In this way, the air outlet speed of the airflow in the first sub-air duct 1111 can be increased, so that the air outlet speed of the low-temperature airflow in the first sub-air duct 1111 is greater than that of the low-temperature airflow in the second sub-air duct 1112. Further, in this way, the low-temperature airflows with different speeds can flow and mix in the first chamber 110, driving the flow of the low-temperature airflow in the first chamber 110 to improve the turbulence degree of the low-temperature airflow and enhance the refrigeration effect. Optionally, at this time, the first fan operates at a low speed to prevent all the low-temperature airflow from surging into the first sub-air duct 1111. Optionally, the sub-air vent 511 corresponding to the first sub-air duct 1111 is the first sub-air vent, and the sub-air vent 511 corresponding to the second sub-air duct 1112 is the second sub-air vent. The flow area of the first sub-air vent is smaller than that of the second sub-air vent to facilitate the average distribution of the airflow in the first sub-air duct 1111 and the second sub-air duct 1112.

[0077] In addition, driven by the first fan, part of the low-temperature airflow flowing into the first chamber 110 can circulate between the first air return vent 532 and the first sub-air outlet 5311, thereby driving the airflow circulation in the first chamber 110 to improve the refrigeration efficiency of the first chamber 110.

[0078] Optionally, on the first air duct plate 610, corresponding to the second sub-air duct 1112, a plurality of second air outlets 5312 are arranged vertically at intervals to increase the air volume of the second sub-air duct 1112.

The air guide rod 410 extends along the length of the second vent 520 and is rotatably disposed at the second vent 520, and the air guide rod 410 can at least be controlled to switch between a first working position and a second working position; the air guide port 420 is arranged to penetrate the air guide rod 410 in a radial direction of the air guide rod 410; the air guide rod 410 rotates to the first working position, and the air guide port 420 is docked with the second vent 520 to open the second vent 520; the air guide rod rotates to the second working position, and the air guide port is staggered with the second vent so that the air guide rod blocks the second vent.

[0080] When the first chamber 110 is switched to cooling, the air guide rod 410 rotates to the first working position; when the first chamber is switched to heating, the air guide rod 410 rotates to the second working position.

[0083] Specifically, the air guide rod 410 rotates along its own axis. When the first chamber 110 needs to be switched to refrigeration, the air guide rod 410 rotates to the first working position, and the air guide port 420 docks with the second vent 520, thereby opening the second vent 520, and then the first chamber 110 and the second chamber 120 can be connected through the second vent 520 and the air guide port 420. At this time, the first damper assembly 300 opens the first vent 51, and the low-temperature airflow circulates between the first air duct 111, the second air duct 121, the first chamber 110 and the first chamber 110, so as to achieve the first chamber 110 and the second chamber 120. The first chamber 110 is cooled; when the first chamber is switched to heating, the air guide rod 410 rotates to the second working position, and the air guide port 420 is staggered with the second vent 520, thereby blocking the second vent 520, and further isolating the first chamber 110 and the second chamber 120. In this way, the high-temperature airflow can circulate between the first chamber 110 and the first air duct 111 to achieve heating of the first chamber 110, while the low-temperature airflow circulates between the second chamber 120 and the second air duct 121 to achieve cooling of the first chamber 110.

[0084] Optionally, along the length direction of the air guide rod 410, that is, the axial direction of the air guide rod 410, a plurality of air guide openings 420 are arranged at intervals. In this way, the air flow flowing out of the first chamber 110 can be dispersed through the plurality of air guide openings 420, thereby indirectly dispersing the air flow entering the second chamber 120 through the second ventilation opening 520, so as to avoid the air flow flowing into the second chamber 120 from being dispersed and prevent the air flow from gathering and blowing directly at the same place.

[0085] Optionally, the second air guide assembly 400 further includes a second drive motor.
