Description

Technical Field

[0001] The present invention relates to the field of refrigeration energy conservation, and specifically to a freezer with a heat exchange function. Background Art

[0002] The refrigeration principle of a freezer is that the compressor works on the refrigeration system. The refrigeration system uses a refrigerant with a low boiling point, which absorbs heat when evaporating and gasifying. To achieve the effect of energy conservation, the existing technical means is to upgrade the fixed-frequency compressor to a variable-frequency compressor. During the operation of the compressor, the compressor needs to overcome the free friction during the startup process. Therefore, frequent startup of the compressor will cause waste of electric energy, and at the same time, the noise is relatively large when the compressor starts.

[0003] A cold storage device, a refrigerator and a refrigeration method, which relate to the technical field of refrigerators, solve the technical problem that when the existing cold storage device is used to refrigerate a refrigerator, it is easy to cause uneven distribution of cold in the refrigerator compartment. The technical solution provides a cold storage device. Since it is provided with an air duct structure inside, the air passing through it can be fully refrigerated; in addition, the air duct structure of the cold storage device cooperates with the air duct of the refrigerator to achieve uniform refrigeration of the refrigerator. The cold storage device also includes a storage battery. During off-peak power consumption periods, the refrigerator operates normally for refrigeration. At the same time, the cold storage agent in the cold storage main body stores cold and the storage battery is charged; during peak power consumption or power outage, the refrigerator stops refrigerating, and the storage battery provides electric energy to drive the fan and the blower, and the cold storage main body is used for refrigeration. By using the storage battery and taking advantage of the peak-valley time-of-use electricity price policy, the electricity utilization rate is improved and the electricity bill is reduced. This technical solution can achieve the effect of saving electricity prices, but it can only achieve air-cooled refrigeration by itself, and air-cooled refrigeration will cause the items stored to dehydrate.

[0004] CN115900170A An energy storage refrigerator and its usage method. The refrigerator includes a box body, a refrigeration unit and an air duct are arranged inside the box body. The controller inside the box body is connected to a power plug. An energy storage unit and a storage battery are also arranged inside the box body. An air suction cover is installed near the heat preservation door body. This technical solution adds an energy storage unit and a storage battery. The energy storage unit is attached to the evaporator and is arranged together with the evaporator at the top inside the box body to store cold when the refrigerator is powered by mains electricity. The storage battery stores electric energy when the refrigerator is operating. After a power outage, the energy storage unit starts to release cold, and the storage battery discharges to drive the evaporation fan to continue working to maintain the continuous flow of the circulating air. The flow of the circulating air brings the cold released by the energy storage unit to the inside of the box body to slow down the speed of the box temperature rise and extend the heat preservation time; the air suction cover can protect the evaporation fan and collect the relatively high-temperature air at the top inside the box body to form an air volume, further reducing the energy consumption of the refrigerator. This technical solution cannot achieve the switching of air-cooled refrigeration while reducing the startup frequency of the compressor. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. For the freezer with heat exchange function, the refrigerant cools the cold storage medium in the cold storage layer, and the compressor in the refrigeration unit continuously operates to reduce the temperature of the cold storage medium to a lower range. After that, the compressor pauses for a period of time. During this time range, the cold storage medium gradually absorbs heat to maintain the low-temperature environment in the cabinet, so that the refrigeration unit can stably work for a long time within a stable range, thus avoiding frequent startup of the refrigeration unit and achieving the effect of energy saving.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] In addition, in this application, descriptions such as "first" and "second" are for descriptive purposes only, and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments may be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0032] As Figures 1-9 shown, a freezer with a heat exchange function includes a cabinet body 1, a cover plate 2 covering the cabinet body 1, and a refrigeration unit 3 installed inside the cabinet body 1 for refrigeration. The cabinet body 1 is composed of an outer covering part and an inner support frame that plays a supporting role. Other devices are supported by the support frame. For example, the refrigeration unit 3 is arranged below the interior of the cabinet body 1. The refrigeration unit 3 includes structures in the prior art such as a compressor, an evaporator, a condenser, an evaporation fan, etc. that refrigerate the refrigerant; a filling layer is provided inside the cabinet body 1. The filling layer includes an inner variable action layer 4. The variable action layer 4 can achieve different effects according to the change of the internal filling material. A bearing cavity 401 is provided inside the variable action layer 4. A heat-conducting liquid is filled inside the bearing cavity 401. A temporary storage cavity 403 for storing the heat-conducting liquid is provided below the cabinet body 1. A circulation pump 404 for changing the storage position of the heat-conducting liquid is provided between the temporary storage cavity 403 and the bearing cavity 401. The circulation pump 404 realizes the change of the liquid flow direction through the forward and reverse rotation of its motor, and a vacuum pump 405 for evacuating the bearing cavity 401. When the inside of the bearing cavity 401 is evacuated, the function of the variable action layer 4 is heat insulation, which can prevent the heat in the cold storage layer 6 from directly acting on the cabinet body 1. At this time, the refrigeration method of the freezer is air cooling. When direct cooling is required, the heat-conducting liquid is injected from the temporary storage cavity 403 into the bearing cavity 401. At this time, the cold storage layer 6 can directly exchange heat with the inside of the cabinet body 1 through the heat-conducting liquid, so as to achieve the effect of direct cooling.

[0033] The outer thermal insulation layer 5 is generally made of foamed foam. A cold storage layer 6 is provided between the thermal insulation layer 5 and the variable action layer 4. The thermal insulation layer 5 can wrap the cold storage layer 6 to prevent heat dissipation of the cold storage layer 6. The cold storage layer 6 includes a cold storage agent cavity 601. A cold storage medium is provided inside the cold storage agent cavity 601. The cold storage medium can be pure water. The selection of the cold storage medium should meet the conditions of large specific heat capacity and non-toxicity. A refrigerant flow channel 603 wrapped inside the cold storage medium is provided inside the cold storage agent cavity 601. The refrigerant flow channel 603 is connected and communicated with the refrigeration unit 3. A air duct 604 is provided on the side of the cold storage layer 6 close to the thermal insulation layer 5. The air duct 604 is connected to the inside of the cabinet body 1 through a circulation component. The circulation component rotates the blades to realize the flow of air between the air duct 604 and the inside of the cabinet body 1.

[0034] During the use process, the refrigerant cools the cold storage medium in the cold storage layer 6. The compressor in the refrigeration unit 3 continuously operates to reduce the temperature of the cold storage medium to a lower range. After that, the compressor pauses for a period of time. During this time range, the cold storage medium gradually absorbs heat to maintain the low-temperature environment inside the cabinet body 1. Thus, the refrigeration unit 3 can stably work for a long time within a stable range, which can avoid frequent startup of the refrigeration unit 3, and further achieve the effect of energy saving.

[0035] For further optimization, a plurality of support partitions 406 are provided inside the bearing cavity 401. Since the bearing cavity 401 needs to be evacuated internally, the support partitions 406 are provided to limit the deformation of the bearing cavity 401. A flow hole 407 for the circulation of the heat-conducting liquid is provided at the connection between the support partition 406 and the inner bottom wall of the bearing cavity 401. Through such a setting, the flow hole 407 can facilitate the flow of the heat-conducting liquid. For further optimization, the bearing cavity 401 includes two heat-conducting plates 411 parallel to the cold storage layer 6. An insulating frame 408 is provided between the two heat-conducting plates 411. A clamping groove 409 is provided on the side of the heat-conducting plates 411 close to each other. The support partition 406 is sleeved inside the clamping groove 409. An insulating layer is provided at the connection between the clamping groove 409 and the support partition 406 to avoid heat transfer. The outer surface of the connection between the heat-conducting plates 411 and the insulating frame 408 is wrapped by a sealing ring 410. Through such a setting, the heat transfer between the two heat-conducting plates 411 on both sides can be restricted, and heat transfer can only be realized when the heat-conducting liquid is injected.

[0036] For further optimization, a baffle 605 for increasing the residence time of the cooling air is provided inside the air duct 604. For example, the baffle 605 is set in a maze shape. A protrusion 606 for increasing the heat exchange area is provided on the cold storage agent cavity 601 located inside the air duct 604. The heat exchange area is increased by setting the punched protrusion 606.

[0037] In an alternative embodiment, the cold storage layer 6 includes a metal plate 607. The cold storage medium is the metal plate 607 itself. Using solid cold storage to replace the original liquid cold storage can increase the specific heat capacity of the cold storage part, thereby increasing the heat storage. The refrigerant flow channel 603 is opened inside the metal plate 607. The refrigerant flow channel 603 is formed by directly drilling holes in the middle of the metal plate 607, and the inside is polished to be smooth. The refrigerant flow channel 603 includes a connecting pipe 608 connecting adjacent channels. The connecting pipe 608 is divided into an arc part and a connecting part. The connecting part is connected to the hole formed by the metal plate 607 by welding.

[0038] In an alternative embodiment, the refrigerant cavity 601 includes multiple internal partition plates 609. Through holes 610 for the refrigerant flow channel 603 to pass through are opened inside the partition plates 609. A sealing gasket 611 is sleeved on the outer surface of the refrigerant flow channel 603 and is clamped on the outer surface of the through hole 610. The sealing gasket 611 is made of cold-resistant rubber. By setting the sealing gasket 611, it can be avoided that the refrigerant drips from the gap of the through hole 610. Through the multiple partition plates 609, the refrigerant cavity 601 can be divided into multiple separate cavities, and the refrigerant is separately arranged in separate cavities. At the same time, such a setting can make the refrigerant dispersed in different positions of the entire refrigerant cavity 601, so that the refrigeration can be more uniform. During the processing of the refrigerant cavity 601, the refrigerant flow channel 603 can be divided into multiple parts. The refrigerant flow channel 603 is welded on both the upper and lower sides of the through holes 610 of the multiple partition plates 609. Adjacent refrigerant flow channels 603 are connected and sealed by a threaded sleeve, and then the multiple partition plates 609 are welded to the refrigerant cavity 601. Finally, the fixing plate on the side with the protrusion 606 of the refrigerant cavity 601 is welded to the whole. Through such a setting, it can be avoided that there are gaps in the multiple partition plates 609 and the use of the sealing gasket 611 can be reduced.

[0039] In an alternative embodiment, a plurality of partition parts 7 are provided inside the cabinet body 1 to divide the cabinet body 1 into a plurality of storage cavities. The air ducts 604 are divided into multiple separate ones, and the air ducts 604 are separately communicated with each storage cavity. The number of the bearing cavities 401 is the same as the number of the storage cavities. An electromagnetic opening and closing valve 412 connected to the circulation pump 404 and the vacuum pump 405 respectively is provided at the bottom of the bearing cavity 401. Through such a setting, the electromagnetic opening and closing valve 412 can be used to control the switching of the air cooling and direct cooling effects of a single storage cavity. When the electromagnetic opening and closing valve 412 works, the vacuum pump 405 and the circulation pump 404 in the specified bearing cavity 401 can be turned on, and the heat-conducting liquid in the bearing cavity 401 can be transferred to the temporary storage cavity 403, so that the air cooling and direct cooling effects can be realized in some storage cavities inside the same cabinet body 1 respectively.

[0040] Further optimization: The cold storage layer 6 is divided into multiple separate layers according to the number of storage cavities. The refrigerant flow channels 603 in each cold storage layer 6 are separately arranged. Through this setting, a certain cold storage layer 6 can be refrigerated individually, thereby reducing the working time of the compressor during overall refrigeration. Control valves are arranged at both the inlet end and the outlet end of the compressor. The flow pipeline of the refrigerant can be changed through the control valves.

[0041] Further optimization: A connecting pipe 413 is arranged at the bottom end of the separation cavity. The connecting pipe 413 is communicated with the adjacent bearing cavity 401. A driving pump 414 for driving the transfer of the heat-conducting liquid is arranged in the middle of the connecting pipe 413. Through this setting, the heat-conducting liquid in two adjacent bearing cavities 401 can flow, and thus the heat exchange between the two bearing cavities 401 can be realized, the high-temperature cold storage layer 6 can be cooled down, and the heat exchange between the adjacent cold storage layers 6 can be achieved, so that the refrigeration unit 3 can be restarted after the overall temperature reaches a certain point. This process includes: First, the heat-conducting liquid in a bearing cavity 401 is pumped into the temporary storage cavity 403 by the circulation pump 404. Then, the heat-conducting liquid in the adjacent bearing cavity 401 is pumped into the temporary storage cavity 403 by the driving pump 414 to realize heat exchange. Then, the coolant in the temporary storage cavity 403 is supplemented into the temporary storage cavity 403 where the coolant is not full by the circulation pump 404.
