[0003] The refrigeration compartment includes the refrigerator and freezer. Conventional multi-temperature zone air-cooled refrigerators usually adopt a single system solution. Each refrigerator and freezer share an evaporator, and the temperature of each compartment is controlled by an electric damper, achieving temperature control of each compartment at a lower cost.

[0004] Since they share the same evaporator, air / odor leakage and temperature interference are common between the rooms. In order to solve the above problems, independent evaporators are set for different rooms, and the corresponding refrigeration system needs to adopt a dual-channel or multi-channel solution, which requires the introduction of solenoid valves to regulate and distribute the refrigerant in the refrigeration pipeline.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0076] The refrigeration device in the present application generally comprises a box body, a door body and a refrigeration system, wherein at least a refrigeration compartment is formed in the box body, and the refrigeration compartment is opened and closed through the door body to meet the requirements of storing and retrieving articles.

[0077] The refrigeration system uses a compressor, condenser, expansion valve and evaporator to perform the refrigeration cycle of the refrigeration equipment. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to achieve cooling of the items in the box.

[0078] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0079] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can cool the items in the box by utilizing the latent heat of evaporation of the refrigerant.

[0080] refer to Figure 1 The refrigeration device involved in the present application is specifically a refrigerator, which includes a box body 100, the box body 100 includes a refrigeration chamber and an equipment chamber 130, the refrigeration chamber includes a refrigerator chamber 110 and a freezer chamber 120, and the front ends of the refrigerator chamber 110 and the freezer chamber 120 are respectively provided with ports for introducing food. The refrigerator chamber 110 is used to insure food, and the freezer chamber 120 is used to freeze food.

[0081] refer to Figure 2-Figure 4 The refrigeration system includes a compressor 200, a condenser 600, a solenoid valve 400, a refrigeration evaporator and a freezing evaporator. The compressor 200, the condenser 600, the solenoid valve 400, the refrigeration evaporator and the freezing evaporator are connected through a refrigerant pipeline.

[0082] The refrigerating evaporator is used to provide cooling to the refrigerating chamber 110 , and the freezing evaporator is used to provide cooling to the freezing chamber 120 .

[0083] The output end of the compressor 200 is connected to the condenser 600, and the solenoid valve 400 is connected to the output end of the condenser 600. The solenoid valve 400 is formed with at least two output ends, one output end of the solenoid valve 400 is connected to the refrigeration evaporator, and the other output end is connected to the freezing evaporator.

[0084] For a refrigeration system including at least two evaporators, the solenoid valve 400 is an important working component. When the width of the box body 100 is relatively small, or when there are many working components arranged in the equipment chamber 130, the installation space of the solenoid valve 400 is limited and the installation process is relatively difficult.

[0085] refer to Figure 5-Figure 7 In order to facilitate the installation of the solenoid valve 400, a support member 500 is installed in the equipment chamber 130 in the present application, and the solenoid valve 400 is connected to the equipment chamber 130 through the support member 500.

[0086] A clamping portion 411 is formed on both sides of the solenoid valve 400 , and a buckle portion 521 is formed at a corresponding position of the support member 500 . The solenoid valve 400 is detachably connected to the support member 500 via the clamping portion 411 .

[0087] That is, the support member 500 is fixed in the equipment chamber 130 , and the solenoid valve 400 is snap-connected to the support member 500 via a snap-fit ​​structure.

[0088] The specific implementation of the clamping portion 411 and the buckle portion 521 is described below:

[0089] Positioning portions 410 extending toward both sides are formed on both sides of the solenoid valve 400 , and the clamping portions 411 are formed on the positioning portions 410 .

[0090] The positioning portion 410 is a positioning plate structure formed on both sides of the solenoid valve 400 , and the clamping portion 411 is specifically a penetrating clamping groove formed on the positioning portion 410 .

[0091] A mounting position 510 is formed on the support member 500 , connecting portions 520 are formed on both sides of the mounting position 510 , and buckle portions 521 are formed on the connecting portions 520 .

[0092] refer to Figure 8-Figure 10 The height of the connecting portion 520 is higher than the bottom of the mounting position 510 , and a connecting channel 511 is formed below the connecting portion 520 . The height of the connecting channel 511 matches the thickness of the positioning portion 410 .

[0093] The positioning portion 410 is connected in the connecting channel 511 , and the buckle portion 521 on the connecting portion 520 is buckled into the corresponding buckle portion 411 .

[0094] Specifically, the inner sides and one end side of the two connecting channels 511 located on both sides of the installation position 510 are open structures.

[0095] Side plates 523 are respectively formed on the connecting parts 520 on both sides of the installation position 510 , and the width of the installation position 510 between the two side plates 523 is adapted to the width of the installation position 510 and the width of the solenoid valve 400 .

[0096] The buckle portion 521 is a buckle structure formed on the connecting portion 520 and having a certain amount of movement along the height direction. A buckle protrusion extending into the connecting channel 511 is formed on the buckle portion 521 .

[0097] During installation, the positioning parts 410 on both sides of the solenoid valve 400 move inward along the connecting channel 511 . As the positioning parts 410 move, the snap-fitting protrusions contact the positioning parts 410 . Under the action of the positioning parts 410 , the snap-fitting parts 411 are pushed upward.

[0098] Until the clamping portion 411 on the positioning portion 410 corresponds to the buckle portion 521 , the clamping protrusion is reset downward to the inside of the clamping portion 411 under the action of its own restoring force, thereby realizing the connection between the solenoid valve 400 and the support member 500 .

[0099] Then, during the actual installation of the solenoid valve 400 , the operator only needs to push the solenoid valve 400 inward along the connecting channel 511 to fix the solenoid valve 400 , without requiring an excessively large operating space, which is conducive to improving work efficiency.

[0100] In some embodiments of the present application, in order to further constrain the vertical position of the solenoid valve 400 and prevent the solenoid valve 400 from moving up and down due to factors such as vibration during the actual operation of the refrigeration equipment.

[0101] The solenoid valve 400 will generate vibrations of a certain amplitude when working, and the key point of assembling it with the support member 500 is to assemble it reliably without looseness.

[0102] Since the above-mentioned assembly is achieved through the elastic deformation of the buckle portion 521 on the support member 500, a certain assembly gap will be left at the relevant limiting structure of the support member 500 after the tolerance matching between the buckle portion 521 and the clamping portion 411.

[0103] After assembly, the solenoid valve 400 will inevitably shake slightly. In order to ensure the long-term reliability of the fitting between the solenoid valve body 400 and the bracket 150 box, and to reduce the noise level of the entire refrigerator, a fastening hole 412 is also formed on the positioning portion 410 involved in the present application.

[0104] A fastening sleeve 522 extending upward is formed at a corresponding position of the connecting portion 520 , and the fastener passes through the fastening hole 412 from bottom to top and is connected in the fastening sleeve 522 .

[0105] The fastening sleeve 522 and the connecting portion 520 are an integrally formed structure.

[0106] In some embodiments of the present application, the inner cavity size of the fastening sleeve 522 is slightly smaller than the connecting end of the fastener. During installation, the connecting end of the fastener is connected to the fastening sleeve 522 in a tight fit.

[0107] Additionally, in some other embodiments, an internal thread is formed in the fastening sleeve 522 , an external thread is formed on the fastener, and a connecting end of the fastener passes through the fastening hole 412 and is threadedly connected in the fastening sleeve 522 .

[0108] During installation, after the solenoid valve 400 is initially connected and fixed through the snap-fit ​​structure, the fastener is passed through the fixing hole from the bottom and connected to the fastening sleeve 522 to further connect and fix the solenoid valve 400 and the support 500 to avoid the adverse effects of vibration during operation of the solenoid valve 400 on assembly reliability and overall noise.

[0109] In other embodiments, the fastening sleeve 522 on the connecting part 520 in the present application can also be set to a hole structure aligned with the fastening hole 412 on the positioning part 410, and the fastener is a bolt structure. The fastener passes through the corresponding fastening hole 412 and the hole on the connecting part 520 to connect the solenoid valve 400 and the support member 500.

[0110] In order to facilitate the fixing of the fasteners, the bottom of the connecting channel 511 is a hollow structure, and the operator can connect and fix the fasteners from the bottom.

[0111] refer to Figure 11-13 A bottom plate 140 is disposed at the bottom of the equipment chamber 130 , and an upward bending portion 141 is formed on the rear side of the bottom plate 140 , and the support member 500 is detachably connected to the bending portion 141 .

[0112] A through hole 143 is formed on the bending portion 141 , and a horizontally arranged connecting sleeve 540 is formed at the end of the supporting member 500 . A connecting inner cavity opening toward the bending portion 141 is formed on the connecting sleeve 540 .

[0113] In some embodiments of the present application, the radial dimension of the connecting inner cavity of the connecting sleeve 540 is slightly smaller than the connecting end of the fastener. During installation, the connecting end of the fastener is connected to the connecting sleeve 540 in a tight fit.

[0114] In other embodiments, an internal thread is formed in the connecting sleeve 540 , and the fixing member is a fastening screw, which passes through the through hole 143 and is connected to the connecting sleeve 540 .

[0115] The connecting sleeve 540 and the support member 500 are an integrally formed structure. The material of the entire support member 500 is plastic, which is formed by injection molding. Reinforcing ribs and other structures are also formed on the support member 500 to improve the structural strength of the entire support member 500.

[0116] The connecting sleeve 540 can increase the contact area between the fastening screw and the support member 500, thereby increasing the connection strength. The use of the fastening screw for one-way connection from the outside is also beneficial in reducing the operating space and facilitating installation.

[0117] Of course, in addition to this, a hole may be opened on the side wall of the support member 500, and the support member 500 and the bending portion 141 may be fixed using fastening bolts.

[0118] In addition, in some other embodiments, the bottom of the support member 500 is also fixed on the base plate 140. Specifically, a limiting portion 530 is formed at the bottom of the support member 500, and a limiting hole 142 is formed at a corresponding position of the base plate 140. In the installed state, the limiting portion 530 of the support member 500 is inserted into the limiting hole 142 to play a role in positioning and connection.

[0119] A stopper is formed on the limiting portion 530 . After the limiting portion 530 is inserted into the limiting hole 142 , the limiting portion 530 is snapped to the bottom of the limiting hole 142 under the action of the stopper.

[0120] The stopper is specifically an elastic structure formed on both sides of the limiting portion 530 and having a certain amount of movement along a direction close to the limiting portion 530 . During installation, the limiting portion 530 passes through the limiting hole 142 .

[0121] During this process, under the action of the limiting hole 142, the stop parts on both sides shrink toward the limiting part 530 until the stop parts are completely located at the bottom of the limiting hole 142. Then, under the action of their own elasticity, the stop parts are reset and connected to the bottom plate 140 through the stop parts.

[0122] In other embodiments, in order to facilitate the movement of the refrigerator, rollers are provided on the bottom plate 140 of the refrigerator compressor 200. However, the compressor 200 has many related wiring harnesses. During the movement of the refrigerator, the rollers of the bottom plate 140 of the compressor 200 are likely to come into contact with the wires, thereby rolling the wiring harnesses into the rollers, causing a safety hazard.

[0123] In order to solve this problem, a roller cover is usually provided on the bottom plate 140 of the compressor 200 to isolate the roller from the wiring harness. However, currently, the roller cover is generally fixed to the bottom plate 140 of the compressor 200 by screws, which is inconvenient to install and has low production efficiency.

[0124] In order to further reduce the number of components, an upwardly extending avoidance recess 550 is formed at a corresponding position of the support member 500 , and the roller is located in the avoidance recess 550 .

[0125] Then, the support member 500 can replace the roller cover structure in the prior art, reduce the number of components, and reduce assembly and production costs.

[0126] refer to Figure 14-16 In some embodiments of the present application, the compressor 200 is connected to the base plate 140 via a support base 210, and a buffer member 220 is also provided between the support base 210 and the base plate 140 to reduce vibration transmission of the compressor 200 during operation.

[0127] Specifically, the buffer member 220 includes a buffer seat 221 and a buffer protrusion 222 formed on the buffer seat 221 . The buffer member 220 is a rubber structure, and the buffer seat 221 and the buffer protrusion 222 are integrally formed.

[0128] refer to Fig.17 A mounting hole 212 is formed on the supporting base 210 . The size of the mounting hole 212 is larger than the buffer protrusion 222 and smaller than the buffer seat 221 . The mounting hole 212 is sleeved on the buffer protrusion 222 .

[0129] The support base 210 is fixed to the bottom of the compressor 200 by welding or mechanical connection.

[0130] Specifically, in order to provide stable support for the compressor 200 , a group of support frames 210 are respectively disposed on both sides of the compressor 200 .

[0131] In addition, the support base 210 of the present application is formed with a conformal surface 211 that is adapted to the outer surface of the bottom position that contacts the compressor 200 , so as to increase the contact area with the compressor 200 .

[0132] The buffer member 220 is further fixedly connected to the support base 210 via a pressing plate 230 . In order to reduce the vibration transmission of the support base 210 , a buffer pad 240 is further provided between the pressing plate 230 and the support base 210 .

[0133] The size of the buffer pad 240 is slightly larger than the size of the mounting hole 212 . During installation, the buffer pad 240 is located between the pressing plate 230 and the supporting base 210 to prevent the transmission of vibration of the supporting base 210 .

[0134] Specifically, the buffer pad 240 is disposed above the buffer protrusion 222 . The buffer pad 240 is an annular structure, and is formed integrally with the buffer protrusion 222 or is a separate structure from the buffer member 220 .

[0135] A middle hole is formed on the buffer member 220 , and a fastening bolt passes through the pressing plate 230 and the middle hole to fix the supporting base 210 on the bottom plate 140 .

[0136] When the buffer member 220 and the buffer pad 240 are an integrated structure, a guide surface gradually expanding from top to bottom is formed on the buffer pad 240, and the buffer pad 240 has a certain elasticity. The mounting hole 212 on the support base 210 passes through the buffer pad 240 and is sleeved on the outside of the buffer protrusion 222. When the pressure plate 230 is pressed onto the buffer pad 240, the buffer pad 240 is compressed, which can further increase the contact area between the support base 210.

[0137] The refrigerating room of the box body 100 is provided with a supporting shelf for placing food and other items that need to be refrigerated or frozen.

[0138] Brackets 150 are disposed on the side walls of the refrigerating chamber 110 and the freezing chamber 120 , and two sides of the supporting shelves are supported on corresponding brackets 150 , respectively.

[0139] In addition to the compressor 200 and the solenoid valve 400 , the equipment chamber 130 is also provided with working parts such as a drying filter 300 , a condenser 600 , a fan 700 , and a drainage pipe group 800 .

[0140] The drying filter 300 mainly plays the role of filtering impurities, and is provided with a molecular sieve and a filter screen, which can adsorb and filter the moisture, metal powder and dust contained in the refrigeration system to clean the refrigerant.

[0141] The drainage pipe set 800 includes a refrigeration drainage pipe and a freezing drainage pipe, which are respectively connected to the refrigeration chamber 110 and the freezing chamber 120 for easy drainage.

[0142] The specific connection and working principle of the drying filter 300, the drainage pipe group 800, etc. are existing technologies and are not the design focus of this application, so they will not be elaborated here.

[0143] The present application also proposes a refrigeration device, which includes a box body 100 in which a refrigeration compartment and an equipment chamber 130 are formed.

[0144] The refrigeration system includes a compressor 200, a condenser 600, a solenoid valve 400, a refrigeration evaporator and a freezing evaporator connected by a refrigerant pipeline. At least two output ends are formed on the solenoid valve 400, and the refrigeration evaporator and the freezing evaporator are respectively connected to the corresponding output ends.

[0145] A support member 500 is provided in the equipment chamber 130 , and the solenoid valve 400 is configured to be detachably connected to the support member 500 by means of a snap connection, so as to reduce the assembly space of the solenoid valve 400 and improve the assembly efficiency.

[0146] The specific method of the snap connection can be achieved by one of the following methods or a combination of several methods:

[0147] Method 1: Reference Fig.18 A buckle portion 521 is provided on the support member 500, and positioning portions 410 are provided on both sides of the solenoid valve 400, and the buckle portion 521 is provided on the side of the positioning portion 410. A clamping groove is provided on the positioning portion 410.

[0148] During installation, the buckle portion 521 moves relative to the surface of the positioning portion 410 under the action of the positioning portion 410 until the buckle portion 521 corresponds to the position of the slot. The buckle portion 521 then returns to its original position under the action of its own restoring force and is locked in the slot.

[0149] Method 2: A through hole 143 structure is also provided at the bottom of the support member 500, and a fastening hole 412 is provided at a corresponding position of the positioning portion 410 of the solenoid valve 400. After the buckle portion 521 on the solenoid valve 400 is snapped into the slot, the fastening hole 412 corresponds to the through hole 143 structure, and the solenoid valve 400 and the support member 500 are further connected by fastening with a bolt structure.

[0150] Method 3: Reference Figure 5 Positioning portions 410 extending toward both sides are formed on both sides of the solenoid valve 400 , and a clamping portion 411 is formed on the positioning portions 410 .

[0151] The positioning portion 410 is a positioning plate structure formed on both sides of the solenoid valve 400 , and the clamping portion 411 is specifically a penetrating clamping groove formed on the positioning portion 410 .

[0152] A mounting position 510 is formed on the support member 500 , connecting portions 520 are formed on both sides of the mounting position 510 , and buckle portions 521 are formed on the connecting portions 520 .

[0153] The height of the connecting portion 520 is higher than the bottom of the mounting position 510 . A connecting channel 511 is formed below the connecting portion 520 . The height of the connecting channel 511 matches the thickness of the positioning portion 410 .

[0154] The positioning portion 410 is connected in the connecting channel 511 , and the buckle portion 521 on the connecting portion 520 is buckled into the corresponding buckle portion 411 .

[0155] Specifically, the inner sides and one end side of the two connecting channels 511 located on both sides of the installation position 510 are open structures.

[0156] The buckle portion 521 is a buckle structure formed on the connecting portion 520 and having a certain amount of movement along the height direction. A buckle protrusion extending into the connecting channel 511 is formed on the buckle portion 521 .

[0157] During installation, the positioning parts 410 on both sides of the solenoid valve 400 move inward along the connecting channel 511 . As the positioning parts 410 move, the snap-fitting protrusions contact the positioning parts 410 . Under the action of the positioning parts 410 , the snap-fitting parts 411 are pushed upward.

[0158] Until the clamping portion 411 on the positioning portion 410 corresponds to the buckle portion 521 , the clamping protrusion is reset downward to the inside of the clamping portion 411 under the action of its own restoring force, thereby realizing the connection between the solenoid valve 400 and the support member 500 .

[0159] Method 4: Based on method 3, a fastening hole 412 is further formed on the positioning portion 410 involved in the present application, and a fastening sleeve 522 extending upward is formed at the corresponding position of the connecting portion 520, and an internal thread is formed in the fastening sleeve 522, and the fastener passes through the fastening hole 412 and is threadedly connected in the fastening sleeve 522.

[0160] The fastening sleeve 522 and the connecting part 520 are an integrally formed structure. During installation, after the solenoid valve 400 is initially connected and fixed by the snap-fit ​​structure, the fastener is passed through the fixing hole from below and connected to the fastening sleeve 522, so as to further connect and fix the solenoid valve 400 and the support 500, so as to avoid the adverse effects of vibration during operation of the solenoid valve 400 on assembly reliability and overall noise.

[0161] In order to facilitate the fixing of the fasteners, the bottom of the connecting channel 511 is a hollow structure, and the operator can connect and fix the fasteners from the bottom.

[0162] The fastening sleeve 522 can increase the contact area between fasteners such as fastening screws and the solenoid valve 400, thereby increasing the connection strength. The use of fastening screws for one-way connection from the bottom is also beneficial in reducing the operating space and facilitating installation.

[0163] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0164] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
