Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a refrigeration equipment structure with improved drainage nozzles and inner tank installation structures. Background Art

[0002] In order to realize the refrigeration function, the existing refrigeration equipment will arrange the evaporator accordingly to perform refrigeration.

[0003] During operation, the condensed water or defrost water on the evaporator needs to be discharged out of the box, so a drainage nozzle structure needs to be arranged accordingly.

[0004] When assembling the drain nozzle, it is installed in the foaming cavity, with one end cooperating with the inner tank and the other end cooperating with the lower bottom steel component on the box shell to lead out the water.

[0005] Existing, the drain nozzle and the inner liner are assembled in parallel, and there is an insertion port on the inner liner. The pipe body of the drain nozzle is inserted into the insertion port without mutual assembly force. After the drain nozzle is connected to the inner liner, it is necessary to use sponge or tape to fix and seal the drain nozzle on the inner liner to prevent the drain nozzle from detaching and prevent the foam material from leaking into the assembly surface of the drain nozzle and the inner liner. The use of tape and sponge for sealing is inconvenient, time-consuming and labor-intensive, and the connection is not firm, and the sealing effect is poor.

[0071] In some embodiments of the present application, a refrigeration device is provided, comprising:

[0072] The box shell 100 is used to form the outer shell of the refrigeration equipment, and can be formed by bending a rigid part.

[0073] The lower bottom steel component 400 is connected and fixed to the box shell 100 .

[0074] and an inner liner component 200 disposed in the box shell 100, wherein a foaming cavity is formed between the inner liner component 200 and the box shell 100;

[0075] When molding the refrigeration device, the inner tank component 200 and the box shell 100 are connected and fixed to form a foaming cavity, and then the foaming material is filled in the foaming cavity. After the foaming material is solidified, the box body is formed.

[0076] In some embodiments of the present application, the inner liner component 200 is formed by vacuum molding, and a storage cavity for storing food is defined therein.

[0077] The storage chamber includes a refrigerating chamber and a freezing chamber arranged below the refrigerating chamber.

[0078] An opening is provided on the storage cavity so that a user can conveniently take out the food in the storage cavity.

[0079] In order to realize opening or closing of the storage cavity, a door body is correspondingly arranged at the opening position.

[0080] In some embodiments of the present application, the door body includes a refrigerating chamber door body and a freezing chamber door body, which are rotatably connected to the refrigerating chamber and the freezing chamber respectively to realize the opening and closing of the refrigerating chamber and the freezing chamber.

[0081] In order to achieve a refrigeration effect on the refrigerator and freezer compartments, in some embodiments of the present application, the refrigeration device is further configured with a refrigeration system.

[0082] The refrigeration system includes a compressor configured to compress a refrigerant;

[0083] a condenser configured to condense the refrigerant;

[0084] an evaporator configured to evaporate the refrigerant condensed by the condenser, wherein the refrigerant evaporated by the evaporator is configured to cool the storage space;

[0085] The refrigerant circulation loop allows the condensate to circulate in a loop consisting of a compressor, an evaporator, a condenser, a solenoid valve and a throttling device;

[0086] The refrigeration system performs the refrigeration cycle of the refrigeration equipment by using a compressor, a condenser, a solenoid valve, an evaporator and a throttling device.

[0087] A refrigerant circulation loop is formed between the compressor, the condenser, the solenoid valve, the evaporator and the throttling device, so that the refrigerant can circulate among the compressor, the condenser, the solenoid valve, the evaporator and the throttling device.

[0088] The refrigeration cycle consists of a series of processes involving compression, condensation, expansion and evaporation to cool the contents of the cabinet.

[0089] 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.

[0090] The evaporator can cool the items in the cabinet by utilizing the latent heat of evaporation of the refrigerant.

[0091] When the evaporator is in refrigeration operation, frost will form on the top of the evaporator, and the frosted defrost water or the condensed water on the top of the evaporator needs to be discharged to the outside of the cabinet through the drain nozzle 300.

[0092] In some embodiments of the present application, an inserting portion 210 protruding from the inner liner component 200 is formed on the inner liner component 200, and an inclined portion 220 arranged downwardly inclined relative to the center line thereof is formed on the inserting portion 210;

[0093] In some embodiments of the present application, the insertion portion 210 is an insertion sleeve, which is arranged at the bottom outer wall of the inner liner component 200, with its center line extending in the horizontal direction. A drain outlet is also formed on the inner liner component 200, and the insertion portion 210 is formed at the drain outlet position and is connected to the drain outlet.

[0094] In some embodiments of the present application, the inclined portion 220 is directly formed on the inserting portion 210 , and is arranged to be inclined downward relative to the horizontal direction.

[0095] The drain nozzle 300 is arranged in the foaming cavity, one end of which is sealed and connected to the inner tank component 200, and the other end passes through the lower bottom steel component 400 and is sealed and connected thereto. The defrost water or condensed water on the evaporator received from the inner tank component 200 can be passed through the foaming cavity by the drain nozzle 300 and discharged outward from the lower bottom steel component 400 and the box shell 100.

[0096] In some embodiments of the present application, the drain nozzle 300 includes:

[0097] The drainage main body component 310 has a drainage channel formed therein, and the drainage channel is used to transport defrost water or condensed water on the evaporator. The center line of the drainage channel is extended along the horizontal direction.

[0098] An inclined matching portion 320 for matching with the inclined portion 220 is formed on the inner wall of the drainage channel;

[0099] In order to achieve matching with the inclined portion 220 , the inclined matching portion 320 is also correspondingly arranged to be inclined, and the inclination angle is matched with the inclined matching portion 320 , which is arranged to be inclined downward relative to the horizontal direction.

[0100] The inclined fitting portion 320 has a first center line, the inclined portion 220 has a second center line, and the insertion portion 210 has a horizontally arranged first horizontal center line, the first center line and the second center line are parallel, and the first center line and the second center line are arranged downwardly inclined relative to the first horizontal center line.

[0101] During installation, the drain nozzle 300 can be inserted into the inclined portion 220 through the inclined matching portion 320 to achieve connection with the inner tank component 200 .

[0102] In some embodiments of the present application, the drainage main body component 310 includes a connection fitting portion 330 extending outwardly from the circumference of one end of the drainage main body component 310, and is used to wrap and fit around the outer side walls of the inner tank component 200;

[0103] The connecting and fitting portion 330 is arranged to form a connecting and fitting cavity, which can be used to receive the condensed water discharged from the drain port of the inner tank. The circular wrapping manner along the surrounding side walls of the inner tank component 200 ensures the tightness of the connection with the inner tank component 200 and avoids the condensed water from flowing out or overflowing.

[0104] During assembly, the drainage main body component 310 is assembled onto the insertion part 210 along the center line direction of the insertion part 210, and the inclined matching part 320 is obliquely assembled into the inclined part 220 so that the contact surfaces of the inner tank component 200 and the drainage nozzle 300 are tightly fitted.

[0105] By providing an inclined portion 220 on the inserting portion 210 of the inner tank component 200 and providing an inclined matching portion 320 on the drainage main body component 310, during assembly, the inclined portion 220 and the inclined inserting matching connection can be achieved.

[0106] A mutually cooperating connection structure is added between the inner liner component 200 and the drain nozzle 300 to realize the connection between the inner liner component 200 and the drain nozzle 300. Compared with the existing method of merely inserting the two into each other and assembling them along the center line, it can prevent the water nozzle from falling off and achieve the effect of firmly fixing the water nozzle, eliminating the need for the operation of bonding and fixing again with tape.

[0107] The structure of the insertion part 210 and the drainage main component 310 requires that the drainage nozzle 300 must be assembled in a horizontal direction, while the structural setting of the inclined part 220 and the inclined matching part 320 requires that the drainage nozzle 300 also needs to be installed inclined along the inclined part 220 during installation.

[0108] When the drain nozzle 300 is installed, the insertion part 210 will limit the horizontal movement of the water outlet, and the inclined part 220 will limit the water outlet to make it deviate from the horizontal direction and move downward. Through the interaction between the two, the drain nozzle 300 can be tightly installed on the inner tank component 200 and maintain a tight fit with the inner tank component 200.

[0109] On the premise that the drainage main body component 310 is assembled along the center line of the insertion part 210, an inclined part 220 and an inclined matching part 320 inclined relative to the center line of the insertion part 210 are added. On the basis of the horizontal force when the water outlet is assembled along the center line of the insertion part 210 to the inner tank component 200, a tensioning force inclined downward relative to the center line direction of the insertion part 210 is added, so that the water outlet can be closely fitted with the contact surface of the inner tank after the assembly is completed, and the foaming material can be prevented from entering, which has a good sealing effect and solves the problem that the contact surfaces of the two are not closely matched in the existing parallel assembly. When foaming, the foaming material will flow between the water outlet and the inner tank component 200, so that the foaming material enters the drainage nozzle 300 and causes the drainage nozzle 300 to be blocked;

[0110] Since the inclined portion 220 and the inclined matching portion 320 cooperate with each other, during assembly, the water outlet nozzle 300 and the inner liner component 200 can be locked and fixed by only sliding the water outlet nozzle along the guiding effect of the inclined matching portion 320 and the inclined portion 220, without the need for tape packaging, and the installation operation is more convenient and quick;

[0111] The structure of the drain nozzle 300 is improved by providing a connection matching portion 330 connected to the drain main body component 310. When the drain nozzle 300 is installed in place, the connection matching portion 330 is wrapped and attached to the side wall of the inner liner component 200 over a large area, so as to realize a large-area attachment connection between the drain nozzle 300 and the inner liner component 200, thereby increasing the attachment contact area between the two, improving the sealing and tightness of the connection between the two, and further preventing the foaming material from entering the drain nozzle 300 through the gap between the inner liner component 200 and the drain nozzle 300 during the foaming process;

[0112] The drainage nozzle 300 and the lower bottom steel mating end of the box shell 100 are sealed to ensure that the foaming material in the foaming cavity will not leak.

[0113] In some embodiments of the present application, the inclined portion 220 is an inclined slot / inclined protrusion formed on the insertion portion 210;

[0114] The inclined fitting portion 320 is an inclined protrusion / inclined slot formed on the inner wall of the drainage channel.

[0115] That is, during the setting, an inclined slot can be arranged on the inserting portion 210 on the inner liner component 200, and the inclined slot can be directly formed integrally with the inner liner component 200 by vacuum molding during the molding.

[0116] Correspondingly, an inclined protrusion is arranged on the inner wall of the drainage channel, and is integrally formed with the drainage main body component 310 during molding.

[0117] During assembly, the drainage channel of the drainage nozzle 300 is sleeved onto the outside of the insertion portion 210 on the inner tank component 200 , and the inclined protrusion on the inner wall thereof is correspondingly inserted into the inclined slot on the outside of the insertion portion 210 .

[0118] In some embodiments of the present application, an inclined protrusion is provided on the insertion portion 210 of the inner liner component 200, and an inclined slot is formed on the inner wall of the drainage channel. During assembly, the inclined slot on the drain nozzle 300 and the inclined protrusion on the inner liner component 200 are obliquely inserted and matched to achieve the connection between the insertion portion 210 and the drainage main body component 310.

[0119] In some embodiments of the present application, the width of the inclined slot along the inclined assembly direction of the drain nozzle 300 gradually increases; the width of the inclined protrusion along its assembly direction gradually increases.

[0120] In some embodiments of the present application, there is an angle between the center line of the inclined portion 220 and the center line of the insertion portion 210, and the angle is less than 30 degrees. The angle can be 15 degrees, 20 degrees or 25 degrees, etc. The inclined portion 220 is set to a smaller inclination angle to ensure an inclined installation between it and the drain nozzle 300.

[0121] In some embodiments of the present application, an angle is formed between a center line of the inclined portion 220 and a center line of the insertion portion 210 , and the angle is 30-60 degrees.

[0122] The angle may be 30 degrees, 40 degrees or 50 degrees, etc. Within this angle range, both the smoothness of the assembly of the drain nozzle 300 and the inner tank component 200 and the tightness of the connection after the two are matched can be guaranteed.

[0123] In some embodiments of the present application, an angle is formed between a center line of the inclined portion 220 and a center line of the insertion portion 210 , and the angle is 60-80 degrees.

[0124] The angle can be 70 degrees or 75 degrees.

[0125] In some embodiments of the present application, the drainage main component 310 includes a main body 311, and a first channel is formed in the main body 311;

[0126] and an assembly portion 312 connected to the main body portion 311 , wherein a second channel is formed in the assembly portion 312 , and the second channel is connected to the first channel to form the drainage channel.

[0127] In some embodiments of the present application, the main body 311 is a main pipe constituting the drainage main component 310, and the assembly part 312 is an assembly pipe connected to the main pipe. The main pipe and the assembly pipe are connected to form a drainage channel.

[0128] In some embodiments of the present application, the drainage main body component 310 is a drainage main pipe fitting, the main body part 311 is a main pipe section, the assembly part 312 is an assembly pipe section, the main pipe section and the assembly pipe section are connected, and during molding, the main pipe section and the assembly pipe section are formed as one piece by injection molding.

[0129] When the inner container component 200 is matched, the inner container component 200 is matched mainly through the assembly portion 312. The connection matching portion 330 is arranged around the circumference of the assembly portion 312. The inclined matching portion 320 is formed on the assembly portion 312.

[0130] During assembly, the assembly portion 312 is sleeved on the insertion portion 210 and inserted into the inclined portion 220 through the inclined matching portion 320. By separately providing the assembly portion 312 that matches the insertion portion 210, a quick assembly connection between the drain nozzle 300 and the inner tank can be achieved.

[0131] In some embodiments of the present application, the assembly portion 312 has a first opening portion 3121 , and the inner diameter of the assembly portion 312 gradually decreases from a direction close to the first opening portion 3121 to a direction away from the first opening portion 3121 ;

[0132] The first opening 3121 is a first opening formed at the end of the assembly portion 312, which is used to connect to the insertion portion 210.
