Description

Technical Field

[0001] This invention belongs to the field of refrigeration equipment technology, and particularly relates to a refrigeration device and its usage method. Background Technology

[0002] Nowadays, there are many types of refrigeration equipment, such as refrigerators and freezers for refrigeration, air conditioners for cooling the environment, and ice cream machines and refrigerated trucks for special purposes. However, no matter how diverse the types of refrigeration equipment are, their core component is the refrigeration system, which mainly consists of compressors, condensers, evaporators, and throttling devices. Different refrigeration equipment uses different refrigeration systems and technologies according to their usage environment and functional requirements. For example, household air conditioners and refrigerators usually use compression refrigeration systems, while some industrial refrigeration equipment may use absorption or vapor jet refrigeration systems.

[0003] As a common refrigeration device, the refrigerator is designed to keep food and other items at a constant low temperature. It is one of the indispensable appliances in modern households. However, refrigerators are very susceptible to the effects of moisture during use. Factors such as daily opening and closing of the cabinet door, the internal temperature setting of the refrigerator, the food itself and the quantity stored, as well as incomplete cleaning can all lead to excessive moisture inside the cabinet.

[0004] For food, excessive humidity can cause dried goods to become damp, leading to nutrient loss and bacterial growth, affecting quality and shelf life. For refrigerators, too much moisture can cause ice to form inside, affecting cooling performance. Therefore, properly preventing excessive humidity inside the refrigerator is crucial for its use and the preservation of dried goods. Currently, most direct-cooling refrigerators cannot solve the problem of excessive humidity inside the cooling system and need improvement. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a refrigeration device and its usage method, which effectively prevents excessive moisture in direct-cooling refrigerators during use.

[0006] In view of the above, the present invention provides a refrigeration device, comprising:

[0007] The cabinet has a refrigerator compartment and a freezer compartment, and both the refrigerator compartment and the freezer compartment are equipped with evaporator components. A humidity sensor is also installed inside the cabinet.

[0008] Cabinet doors are used to open and close the cabinet.

[0009] A drying mechanism is installed on the inner wall of the cabinet and is used to reduce the humidity inside the cabinet.

[0010] The regeneration mechanism is installed on the back of the cabinet and is used to regenerate the drying mechanism.

[0011] In the above technical solution, the drying mechanism further includes:

[0012] A heat insulation cover is installed on the inner wall of the cabinet and forms a drying cavity with the inner wall of the cabinet.

[0013] The cylinder is installed inside the drying chamber, and a desiccant is placed inside the cylinder;

[0014] The heat insulation cover has a first through hole on its side wall and a second through hole on the cylinder corresponding to the first through hole.

[0015] In the above technical solution, further:

[0016] A third through hole is provided on the inner wall of the cabinet;

[0017] The cylinder is rotatably connected inside the drying chamber;

[0018] The top of the heat insulation cover is equipped with a drive device for driving the cylinder to rotate, and after the cylinder rotates, the second through hole switches between being connected to the first through hole and being connected to the third through hole.

[0019] In the above technical solution, the regeneration mechanism further includes:

[0020] The condenser, installed at the back of the cabinet, is used to condense high-temperature, high-pressure refrigerant vapor into liquid and release heat.

[0021] The housing is installed at both ends of the condenser and encloses the third through hole;

[0022] A fan is mounted on the inner wall of the housing near the condenser and is used to draw heat released from the condenser into the housing.

[0023] The casing has an outlet on the inner wall on the side away from the condenser.

[0024] In the above technical solution, further:

[0025] There are at least two cylinders, and there are two second through holes on the cylinders, which are set vertically;

[0026] A first partition is provided inside the shell;

[0027] The first baffle is used to guide the hot air generated by the fan into the cylinder.

[0028] In the above technical solution, further:

[0029] Multiple sealing points are provided between the surface of the cylinder and the inner wall of the heat insulation cover;

[0030] Among them, multiple sealing points are located on both sides of the first through hole and on both sides of the third through hole.

[0031] In the above technical solution, further:

[0032] The cylinder body is made of heat-insulating material.

[0033] Furthermore, the above technical solution also includes:

[0034] The second partition is installed inside the cylinder and is used to form a multi-layer structure inside the cylinder.

[0035] Furthermore, the above technical solution also includes:

[0036] The control unit, installed inside the cabinet, receives feedback from the humidity sensor and controls the start and stop of the drive unit and fan based on the feedback.

[0037] This invention provides a method for using a refrigeration device, comprising the following steps:

[0038] S1: Preset the rated humidity range for the refrigerator and freezer compartments;

[0039] S2: The equipment is powered on and started;

[0040] S3: The humidity sensor continuously monitors the humidity inside the cabinet and sends the feedback to the control unit;

[0041] S4: The control unit compares the humidity reading from the humidity sensor with the preset rated humidity range.

[0042] ①: When the real-time humidity is within the rated humidity range, return to S3;

[0043] ②: When the real-time humidity is not within the rated humidity range and the real-time humidity is less than the minimum value within the rated humidity range, proceed to S5;

[0044] ③: When the real-time humidity is not within the rated humidity range and the real-time humidity is greater than the maximum value within the rated humidity range, proceed to S6;

[0045] S5: The control unit controls the drive device to start, and aligns the two second through holes on the cylinder with the third through hole and the adjacent cylinder respectively, and then starts the fan until the control unit receives the real-time humidity within the rated humidity range, and then returns to S3;

[0046] S6: The control unit starts the drive unit and aligns the two second through holes on the cylinder with the first through hole and the heat insulation cover respectively. Then the fan is turned off until the control unit receives the real-time humidity within the rated humidity range, and then returns to S3.

[0047] The beneficial effects of this invention are as follows:

[0048] 1. By installing a drying mechanism inside the cabinet and detecting the moisture inside the cabinet using a moisture sensor, when the moisture inside the cabinet is too high, the drying mechanism absorbs the moisture, thereby reducing the impact of the moisture inside the cabinet. The regeneration mechanism can effectively improve the sustainability and duration of the drying mechanism, ensuring the absorption effect of excessive moisture inside the cabinet.

[0049] 2. By setting the first and second through holes and placing desiccant inside the cylinder, the moisture inside the cabinet is absorbed by the desiccant. The structure is simple and the manufacturing cost is low. In addition, the cylinder is rotatable, which allows for adjustment of the use of desiccant. Specifically, the desiccant can be switched between drying and regeneration to ensure the sustainability of drying.

[0050] 3. By using a heat insulation cover and heat insulation material for the cylinder, the heat during regeneration can be prevented from affecting the temperature inside the cabinet, thus ensuring the performance and service life of the evaporator components.

[0051] 4. By using a fan to guide the heat released by the condenser outside the cabinet to regenerate the desiccant, on the one hand, additional heat sources are avoided, achieving energy-saving effects; on the other hand, the heat dissipation effect of the condenser is improved, ensuring the cooling effect of the refrigeration equipment.

Detailed Implementation

[0060] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0061] Example 1:

[0062] This embodiment provides a refrigeration device, including:

[0063] Cabinet 1 has a refrigerator compartment and a freezer compartment, and both the refrigerator compartment and the freezer compartment are equipped with evaporator components. A humidity sensor is also installed inside cabinet 1.

[0064] Cabinet door 2 is used to open and close cabinet 1;

[0065] The drying mechanism 3 is installed on the inner wall of the cabinet 1 and is used to reduce the humidity inside the cabinet 1;

[0066] The regeneration mechanism 4 is installed on the back of the cabinet 1 and is used to regenerate the drying mechanism 3;

[0067] The humidity sensor is a mature technology that can be used in low-temperature environments, while the evaporator assembly is a common refrigerator component, and its specific structure will not be described in detail here.

[0068] As can be seen from this embodiment, by setting a drying mechanism 3 inside the cabinet 1 and detecting the moisture inside the cabinet 1 through a moisture sensor, when the moisture inside the cabinet 1 is too high, the drying mechanism 3 absorbs the moisture, thereby reducing the impact of the moisture inside the cabinet 1. The regeneration mechanism 4 can effectively improve the sustainable effect and time of the drying mechanism 3, ensuring the absorption effect of excessive moisture inside the cabinet 1.

[0069] Example 2:

[0070] This embodiment provides a refrigeration device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the drying mechanism 3 includes:

[0071] The heat insulation cover 30 is installed on the inner wall of the cabinet 1 and forms a drying cavity with the inner wall of the cabinet 1.

[0072] The cylinder 31 is installed inside the drying chamber, and a desiccant is placed inside the cylinder 31;

[0073] The heat insulation cover 30 has a first through hole 32 on its side wall and a second through hole 33 on the cylinder 31 that corresponds to the first through hole 32.

[0074] Furthermore, both the first through hole 32 and the second through hole 33 are provided with grids, and the cylinder 31 is provided with a container for placing desiccant;

[0075] Meanwhile, the desiccant is silica gel desiccant, which ensures that it can be used for a long time at low temperatures, while the heat insulation cover 30 can be made of aerogel material, specifically including a cover body made of PP material and aerogel filled in the cover body.

[0076] As can be seen from this embodiment, the heat insulation cover 30 can avoid the impact on the use of the refrigerator when the desiccant is regenerated, and reduce the impact on the temperature inside the cabinet 1. The first through hole 32 and the second through hole 33 facilitate the absorption of moisture inside the cabinet 1.

[0077] The grid and the container for holding the desiccant inside the cylinder 31 can confine the desiccant within the heat insulation cover 30, preventing the desiccant from falling out of the heat insulation cover 30 and affecting the use of the refrigerator.

[0078] Example 3:

[0079] This embodiment provides a refrigeration device, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0080] A third through hole 34 is provided on the inner wall of cabinet 1;

[0081] The cylinder 31 is rotatably connected to the drying chamber;

[0082] The heat insulation cover 30 is provided with a drive device 35 at the top for driving the cylinder 31 to rotate. After the cylinder 31 rotates, the second through hole 33 switches between being connected to the first through hole 32 and being connected to the third through hole 34.

[0083] Meanwhile, the third through hole 34 is provided with a grid, and the driving device 35 can be an electromagnetic motor, which drives the cylinder 31 to rotate through intersecting shaft gears. Support plates that are connected and fixed to the cabinet 1 are also provided at both ends of the cylinder 31, and a rotating shaft is fixedly provided inside the cylinder 31. The two ends of the rotating shaft pass through the cylinder 31 and are connected to the bearings of the support plate.

[0084] As can be seen from this embodiment, by rotating the cylinder 31 inside the drying chamber and opening a third through hole 34 on the inner wall of the cabinet 1, it is convenient for the regeneration mechanism 4 to regenerate the desiccant, and to avoid affecting the temperature inside the cabinet 1 when regenerating the desiccant, thus ensuring the performance of the refrigerator.

[0085] The grid can prevent too many impurities from entering the cylinder 31.

[0086] Example 4:

[0087] This embodiment provides a refrigeration device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the regeneration mechanism 4 includes:

[0088] The condenser 40 is installed on the back of the cabinet 1 and is used to condense high-temperature and high-pressure refrigerant vapor into liquid and release heat.

[0089] The housing 41 is installed at both ends of the condenser 40 and encloses the third through hole 34.

[0090] Fan 42 is mounted on the inner wall of housing 41 near the condenser 40 and is used to introduce the heat released by condenser 40 into housing 41.

[0091] Among them, an outlet 43 is provided on the inner wall of the shell 41 on the side away from the condenser 40;

[0092] Meanwhile, the shell 41 and the cabinet 1 are detachably connected, which facilitates the maintenance and replacement of the drying structure. The outlet 43 is equipped with a grid, and the condenser 40 is a mature existing technology. Its specific structure will not be described in detail here.

[0093] As can be seen from this embodiment, by using the heat released by the condenser 40 and generating hot air through the fan 42, and using this hot air to regenerate the desiccant, on the one hand, additional heat sources are avoided, achieving an energy-saving effect; on the other hand, the heat dissipation effect of the condenser 40 is improved, ensuring the cooling effect of the refrigeration equipment.

[0094] Example 5:

[0095] This embodiment provides a refrigeration device, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0096] There are at least two cylinders 31, and there are two second through holes 33 on the cylinders 31, which are arranged vertically;

[0097] A first partition 44 is provided inside the housing 41;

[0098] The first partition 44 is used to guide the hot air generated by the fan 42 into the cylinder 31;

[0099] Meanwhile, there are two cylinders 31, and the first partition 44 is an integral structure with the shell 41. The gap between the first partition 44 and the two cylinders 31 is set accordingly.

[0100] As can be seen from this embodiment, by setting two cylinders 31 and by setting the first partition 44, the hot air generated by the fan 42 enters the first cylinder 31 and enters the second cylinder 31 through the vertically set second through hole 33, and then exits through the shell 41 and the outlet 43, which can improve the drying effect of the desiccant. Moreover, the hot air is discharged from both sides of the cabinet 1, which can avoid the influence of the hot air on the temperature inside the cabinet 1.

[0101] Example 6:

[0102] This embodiment provides a refrigeration device, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0103] Multiple sealing points 5 are provided between the surface of the cylinder 31 and the inner wall of the heat insulation cover 30;

[0104] Among them, multiple sealing points 5 are located on both sides of the first through hole 32 and on both sides of the third through hole 34, respectively;

[0105] Meanwhile, the surface of the cylinder 31 is provided with polytetrafluoroethylene protrusions at the contact point with the heat insulation cover 30 to ensure the sealing performance and wear resistance of the contact point between the surface of the cylinder 31 and the inner wall of the heat insulation cover 30.

[0106] As can be seen from this embodiment, by setting multiple sealing points 5 on both sides of the first through hole 32 and the third through hole 34, the sealing performance between the cylinder 31 and the heat insulation cover 30 is ensured, so that regardless of whether it is in a drying state or a regeneration state, the inside of the cabinet 1 can be isolated from the outside, avoiding affecting the temperature inside the cabinet 1 and ensuring the performance of the refrigerator.

[0107] Example 7:

[0108] This embodiment provides a refrigeration device, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0109] The cylinder 31 is made of heat-insulating material and is made of polystyrene foam.

[0110] As can be seen from this embodiment, by using heat-insulating material for the cylinder 31 and combining it with the heat insulation cover 30, the heat during regeneration can be prevented from affecting the temperature inside the cabinet 1, thus ensuring the performance and service life of the evaporator components.

[0111] Example 8:

[0112] This embodiment provides a refrigeration device, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and further includes:

[0113] The second partition 36 is installed inside the cylinder 31 and is used to form a multi-layer structure inside the cylinder 31.

[0114] As can be seen from this embodiment, by setting the second partition 36, a multi-layer structure is formed inside the cylinder 31, which increases the contact area between the desiccant and the moisture inside the cabinet 1, improves the absorption of moisture, and promotes the reduction of moisture inside the refrigerator.

[0115] Example 9:

[0116] This embodiment provides a refrigeration device, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and further includes:

[0117] The control unit is installed inside the cabinet 1 and is used to receive feedback from the humidity sensor and control the start and stop of the drive unit 35 and the fan 42 according to the feedback.

[0118] The control unit is a mature existing technology, and its specific structure will not be described in detail here.

[0119] As can be seen from this embodiment, by receiving feedback from the humidity sensor through the control unit and automatically controlling the drive device 35 and the fan 42, the humidity regulation inside the cabinet 1 can be automated.

[0120] Example 10:

[0121] This embodiment provides a method for using a refrigeration device, including the following steps:

[0122] S1: Preset the rated humidity range for the refrigerator and freezer compartments;

[0123] S2: The equipment is powered on and started;

[0124] S3: The humidity sensor continuously monitors the humidity inside cabinet 1 and sends the feedback to the control unit;

[0125] S4: The control unit compares the humidity reading from the humidity sensor with the preset rated humidity range.

[0126] ①: When the real-time humidity is within the rated humidity range, return to S3;

[0127] ②: When the real-time humidity is not within the rated humidity range and the real-time humidity is less than the minimum value within the rated humidity range, proceed to S5;

[0128] ③: When the real-time humidity is not within the rated humidity range and the real-time humidity is greater than the maximum value within the rated humidity range, proceed to S6;

[0129] S5: The control unit controls the drive device 35 to start, and aligns the two second through holes 33 on the cylinder 31 with the third through hole 34 and the adjacent cylinder 31 respectively, and then starts the fan 42 until the control unit receives the real-time humidity within the rated humidity range, and returns to S3;

[0130] S6: The control unit controls the drive device 35 to start, and aligns the two second through holes 33 on the cylinder 31 with the first through hole 32 and the heat insulation cover 30 respectively, and then turns off the fan 42 until the control unit receives the real-time humidity within the rated humidity range, and returns to S3;

[0131] The refrigerator compartment is usually used to store fruits and vegetables, so its rated humidity range is higher than that of the freezer compartment. For example, the rated humidity range of the refrigerator compartment can be 45%-55%, while that of the freezer compartment can be 25%-35%.

[0132] As can be seen from this embodiment, the above method can not only effectively control and reduce the humidity inside the cabinet 1, but also remove the drying mechanism 3 when the humidity inside the cabinet 1 is too low, so as to facilitate the increase of humidity and achieve the effect of reasonably controlling the humidity of the cabinet 1, ensuring the humidity requirements of the refrigerator and freezer compartments, and ensuring the preservation of food by the refrigerator.

[0133] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
