Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigerator equipment, in particular to a horizontal refrigerator. BACKGROUND

[0002] The refrigerator is another name for the refrigerator and the refrigerator. Its refrigeration principle is generally as follows: the compressor in the refrigerator inhales low-temperature and low-pressure refrigerant vapor and compresses it into high-temperature and high-pressure liquid refrigerant. Then the high-temperature and high-pressure liquid refrigerant flows into the condenser to dissipate heat and become high-pressure and low-temperature liquid refrigerant. Then the high-pressure and low-temperature liquid refrigerant enters the evaporator through the capillary tube. When the refrigerant enters the evaporator from the narrow capillary tube into the space, the internal pressure is released instantaneously, gasified, and absorbs heat to change back to low-temperature and low-pressure refrigerant vapor. Then it is inhaled again by the compressor to form a cycle. The refrigerator is divided into direct cooling and air cooling. The direct cooling refers to the evaporator attached to the side wall of the refrigeration cavity to cool the refrigeration cavity. Its disadvantage is that the air in the refrigeration cavity does not flow, and ice is easily formed on the side wall. The air cooling refers to placing the evaporator in a container to make the air in the refrigeration cavity flow through the container to form cold air, which is then blown into the refrigeration cavity. Its advantage is that ice crystals are not formed in the refrigeration cavity, and defrosting is needed after a long period of work. Although the temperature in the refrigerator is low, low temperature can only inhibit the activity of bacteria, and a large number of bacteria will still breed in the refrigerator after a long period of use. These bacteria will cause the food in the refrigerator to deteriorate.

[0003] Chinese patent CN114508885A discloses a horizontal refrigerator with air cooling, which filters and deodorizes the air in the refrigerator by setting ultraviolet lamps and a filtering system in the refrigerator, disinfects the storage space in the refrigerator with ultraviolet rays, eliminates microorganisms inside, inhibits the reproduction of bacteria inside the refrigerator, prolongs the time of producing odor inside the refrigerator, avoids the occurrence of odor mixing when food is stored in the refrigerator, and reduces the cleaning frequency of the refrigerator by the user.

[0004] The above technical solution can purify the air by filtering the activated carbon on the filterable plate, but the humidity in the refrigerator is very heavy, which can quickly saturate the activated carbon, making it difficult to purify the air for a long time. At the same time, the accumulation of a large amount of refrigerated goods in the refrigerator will make it difficult for ultraviolet rays to irradiate the bottom of the refrigerator and the inside of the air duct for sterilization, resulting in poor sterilization effect. During daily use of the refrigerator, artificial periodic sterilization and cleaning of the refrigerator are still needed to remove the odor and bacteria inside the refrigerator, but the air duct needs to be disassembled for cleaning, which wastes manpower and affects cleaning efficiency, making cleaning difficult. Professional cleaning personnel are needed for each cleaning, increasing the use cost. SUMMARY

[0005] In view of the problems existing in the prior art, the present application provides a horizontal refrigerator, which can effectively automatically clean the air duct through the self-cleaning air supply rail to ensure the cleaning quality and efficiency and save the use cost.

DETAILED DESCRIPTION

[0034] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in combination with the drawings and specific embodiments.

[0035] As Figures 1 to 13 shown:

[0036] A horizontal refrigerator, comprising a self-cleaning air supply rail mounted between the refrigeration space and the evaporator 2 inside the refrigerator body 1, the self-cleaning air supply rail comprising a mounting baffle 3 mounted on the inner wall of the refrigerator body 1, an air supply device 4 mounted on the mounting baffle 3, an air guide rail 5 mounted on the mounting baffle 3, a lifting device 6 and a self-rotation guide mechanism 7 symmetrically mounted inside the air guide rail 5, a rotary brush 8 mounted on the movable end of the lifting device 6 and the self-rotation guide mechanism 7, and a plugging plate 9 for plugging the air outlet hole 54 of the air guide rail 5.

[0037] The air guide track 5 of the self-cleaning air supply track and the mounting baffle 3 are assembled to form a ventilation duct. The interior of the freezer body 1 is used to store frozen items. When refrigeration is needed, the evaporator 2 will generate cold air, and the air supply device 4 will suck the cold air into the ventilation duct, and the ventilation duct will transport the cold air to the interior of the freezer to refrigerate the items inside. After the freezer has been used for a long time, it is necessary to sterilize and clean the interior of the freezer regularly to remove odor and bacteria inside the freezer. When cleaning, the user takes out the refrigerated items inside the freezer and cleans the inner wall of the freezer with a sterilizing cleaning liquid to remove odor from the inner wall of the freezer. When the ventilation duct needs to be cleaned, the user blocks the air outlet end of the air guide track 5 through the blocking plate 9, so that the air guide track 5 cannot circulate, and the air supply device 4 can automatically seal, so that the air guide track 5 and the mounting baffle 3 are in a sealed state. The user then adds cleaning liquid to the inside of the air guide track 5 and the mounting baffle 3 to make the sterilizing cleaning liquid soak When the brush 8 moves up and down, it drives the self-rotating guide mechanism 7 to move synchronously. When the self-rotating guide mechanism 7 moves, it drives the self-rotating brush 8 to rotate. When the self-rotating guide mechanism 7 rotates, the self-rotating brush 8 frictionally cleans the inner walls of the air guide track 5 and the mounting baffle 3. The rotating brush 8 and the cleaning liquid cooperate to effectively clean the inner walls of the air guide track 5 and the mounting baffle 3. After the inner walls of the air guide track 5 and the mounting baffle 3 are cleaned, the user discharges the cleaning liquid. After the cleaning liquid is discharged, the user removes the blocking plate 9. After the blocking plate 9 is removed, the air supply device 4 is unsealed at the same time, and the air supply is rotated to circulate the air between the air guide track 5 and the mounting baffle 3, so that the ventilation duct between the air guide track 5 and the mounting baffle 3 is air-dried.

[0038] like Figure 2 and Figure 3 As shown:

[0039] The mounting baffle 3 is mounted between the refrigeration space inside the refrigerator body 1 and the evaporator 2 . A plurality of limit slots 31 are provided on the mounting baffle 3 . A vent 32 is also provided on the mounting baffle 3 .

[0040] The mounting baffle 3 is installed between the refrigerated space inside the freezer body 1 and the evaporator 2 to isolate the interior of the freezer body 1 from the evaporator 2. At the same time, the mounting baffle 3 is used to guide the cold air generated by the evaporator 2 to the vent 32 position, which is convenient for the air supply device 4 to suck and transport the cold air. The limiting slot 31 on the mounting baffle 3 is used to limit the installation of the air guide track 5. After the mounting baffle 3 and the air guide track 5 are installed, a ventilation duct will be formed to facilitate the guidance of cold air circulation. The vent 32 on the mounting baffle is used to circulate the cooling gas generated by the evaporator 2.

[0041] like Figure 2 and Figure 4 As shown:

[0042] The air supply device 4 comprises an air inlet track 41 installed at the position of the air vent 32, a plurality of air inlets 411 are arranged on the air inlet track 41, an air supply fan 42 is installed on the air inlet track 41, and a sealing plugging mechanism 43 is installed on the air inlet track 41.

[0043] When the inside of the refrigerator body 1 needs to be refrigerated, the evaporator 2 will generate cold air, and the baffle 3 is installed to concentrate and guide the cold air generated by the evaporator 2 to the position of the air vent 32. When the air supply fan 42 rotates, the cold air will pass through the air vent 32 of the installed baffle 3 and enter the air duct between the air guide track 5 and the installed baffle 3, and the air duct will then circulate and deliver the cold air to the inside of the refrigerator body 1 for refrigeration. However, when the air duct between the air guide track 5 and the installed baffle 3 needs to be cleaned, the sealing plugging mechanism 43 is switched to seal all the air inlets 411 of the air inlet track 41 to prevent cleaning liquid from flowing out.

[0044] As shown in Figure 4 and Figure 5 :

[0045] The sealing plugging mechanism 43 comprises a linear actuator 432 installed on the air inlet track 41, a telescopic support 431 is installed on the output end of the linear actuator 432, a plurality of limiting guide columns 4311 are arranged on the telescopic support 431 and are in sliding connection with the air inlet track 41, and a plurality of sealing plugging blocks 4312 are installed on the telescopic support 431.

[0046] The linear actuator 432 is preferably an electric push rod. When the air duct between the air guide track 5 and the installed baffle 3 needs to be cleaned, the electric push rod drives the telescopic support 431 to retract and move. When the telescopic support 431 retracts and moves, it is guided to move by the guide columns, so that the telescopic support 431 stably retracts and moves. When the telescopic support 431 moves, it will drive the plurality of sealing plugging blocks 4312 to retract and move synchronously. When the telescopic support 431 is adjusted with the air inlet track 41, the sealing plugging blocks 4312 will be in contact with the air inlets 411 at the same time, effectively sealing the air inlets 411 to prevent cleaning liquid from entering the evaporator 2 during cleaning, causing damage to the equipment.

[0047] As shown in Figure 2 and Figure 6 :

[0048] The air guide track 5 is symmetrically provided with a mounting clamping block 51, a sealing cover plate 52 is installed on the air guide track 5, an adding port 521 is arranged on the sealing cover plate 52, a sealing layer 53 is arranged on the contact surface between the air guide track 5 and the installed baffle 3, a plurality of air outlet holes 54 are arranged on the side of the air guide track 5, the air outlet holes 54 are evenly distributed at equal intervals, a tapered bottom surface 55 is arranged on the bottom of the air guide track 5, and a drain pipe 56 is installed on the tapered bottom surface 55.

[0049] When the air guide rail needs to be assembled on the side of the installation baffle 3 to form an air duct, the staff will insert the installation card on the air guide rail 5 into the limiting card slot 31 of the installation baffle 3 during assembly, and at the same time, the sealing layer 53 on the air guide rail 5 will be in contact with the installation baffle 3 to effectively ensure the sealing, so that the air guide rail 5 and the installation baffle 3 are clamped with each other to form an air duct. When circulating ventilation and refrigeration are needed, the air supply device 4 will deliver cold air into the air duct, and the air outlet hole 54 on the side of the air guide rail 5 will evenly disperse and circulate the cold air to the inside of the refrigerator body 1 for refrigeration. When the air duct needs to be cleaned due to the accumulation of bacteria for a long time, the user will plug all the air outlet holes 54 on the air guide rail 5 by using the plugging plate 9, and at the same time, the air supply device 4 will switch the state of the sealing plugging mechanism 43 to plug all the air inlets 411 of the air inlet rail 41, so as to seal the air duct between the air guide rail 5 and the installation baffle 3. Then, the user will open the adding port 521 on the sealing cover plate 52 to add cleaning liquid into the sealed air duct, so that the sterilizing cleaning liquid can soak the inner walls of the air guide rail 5 and the installation baffle 3. After the sterilizing cleaning liquid soaks the inner walls of the air guide rail 5 and the installation baffle 3 for a certain period of time, the lifting device 6 will move the rotating brush 8 up and down between the air guide rail 5 and the installation baffle 3. When the rotating brush 8 moves up and down, it will drive the self-rotation guide mechanism 7 to move synchronously. When the self-rotation guide mechanism 7 moves, it will drive the rotating brush 8 to rotate. When the rotating brush 8 rotates, it will rub and clean the inner walls of the air guide rail 5 and the installation baffle 3. The rotating rotating brush 8 and the cleaning liquid can effectively clean the inner walls of the air guide rail 5 and the installation baffle 3. After the inner walls of the air guide rail 5 and the installation baffle 3 are cleaned, the user will open the drain pipe 56 to drain the cleaning liquid. The conical bottom surface 55 at the bottom of the air guide rail 5 is used to guide and converge the cleaning liquid to the drain pipe 56, thereby effectively improving the drainage efficiency.

[0050] As shown in Figure 7 and Figure 8 :

[0051] The lifting device 6 includes a ball screw sliding table 61 installed on the inner wall of the air guide rail 5. A first rotating joint 62 is installed on the movable end of the ball screw sliding table 61. A limiting installation hole 621 is installed on the first rotating joint 62.

[0052] The rotating brush 8 is installed between the first rotating joint 62 and the autorotation guide mechanism 7. After the sterilization cleaning liquid invades the air guide rail 5 and the inner wall of the installed baffle 3 for a certain period of time, the rotating brush 8 needs to be driven to move up and down to clean the air guide rail 5 and the inner wall of the installed baffle 3. The ball screw sliding table 61 drives the first rotating joint 62 to move up and down, and the first rotating joint 62 drives the rotating brush 8 to move synchronously when moving up and down. The rotating brush 8 drives the autorotation guide mechanism 7 to move synchronously when moving, and the autorotation guide mechanism 7 drives the rotating brush 8 to autorotate when moving up and down. The rotating brush 8 moves up and down and autorotates to effectively clean the air guide rail 5 and the inner wall of the installed baffle 3, effectively ensuring the cleaning effect.

[0053] As shown in Figure 7 and Figure 9 :

[0054] The autorotation guide mechanism 7 includes a limiting sliding rail 71 installed inside the air guide rail 5, a brake rotating head 73 installed on the limiting sliding rail 71, a rotating gear 74 installed on the brake rotating head 73, and a fixed rack 72 installed on the limiting sliding rail 71. The fixed rack 72 is engaged with the rotating gear 74.

[0055] The brake rotating head 73 is used to connect and install the rotating brush 8. The ball screw sliding table 61 drives the first rotating joint 62 to move up and down, and the first rotating joint 62 drives the rotating brush 8 to move synchronously when moving up and down. The rotating brush 8 drives the brake rotating head 73 to move synchronously along the limiting sliding rail 71 when moving, and the brake rotating head 73 drives the rotating gear 74 to move synchronously when moving. The rotating gear 74 rotates when moving, and the rotating brush 8 rotates synchronously when the rotating gear 74 rotates, effectively driving the rotating brush 8 to autorotate and improving the cleaning effect.

[0056] As shown in Figure 9 , Figure 10 and Figure 11 :

[0057] The brake rotating head 73 includes a limiting sliding block 731 installed on the limiting sliding rail 71, a rotating installation hole 7311 provided on the limiting sliding block 731, a rotating rod 732 installed in the rotating installation hole 7311, a brake block 7321 installed on the rotating rod 732, a second rotating joint 733 provided on one end of the rotating rod 732 away from the brake block 7321, a positioning installation hole 7331 provided on the second rotating joint 733, and a spring 734 provided between the rotating rod 732 and the limiting sliding block 731.

[0058] When the rotating brush 8 needs to be replaced regularly for long-term use, the user opens the sealing cover plate 52 of the air guide rail 5, and then pushes the rotating brush 8 towards the second rotating joint 733. After the second rotating joint 733 is extruded, it will shrink and extrude the spring 734, so that one end of the rotating brush 8 is separated from the limiting installation hole 621 of the first rotating joint 62. Then the user presses the second rotating joint 733, and pulls out the other end of the rotating brush 8 from the positioning installation hole 7331 of the second rotating joint 733, so that the rotating brush 8 can be disassembled. After the rotating brush 8 is disassembled, the worker stops pressing the second rotating joint 733, and the spring 734 drives the second rotating joint 733 to extend and reset. At the same time, the rotating rod 732 moves, and the brake block 7321 of the rotating rod 732 comes into contact with the inner wall of the limiting sliding block 731, so that the rotating rod 732 cannot rotate. The rotating gear 74 also stops rotating and cannot move downward. Only by replacing the rotating brush 8 can it move, effectively preventing the replacement of the rotating brush 8.

[0059] As shown in Figure 6 , Figure 7 , and Figure 12 :

[0060] The rotating brush 8 includes a rotating shaft clamped and installed between the first rotating joint 62 and the second rotating joint 733. One end of the rotating shaft is provided with a first adapter 82, which is adapted to the first rotating joint 62. The end of the rotating shaft away from the first adapter 82 is provided with a second adapter 83, which is adapted to the second rotating joint 733. The rotating shaft is provided with a cleaning brush 81 for cleaning the air duct.

[0061] The first adapter 82 on the rotating shaft is used for clamping and installing in the limiting installation hole 621 of the first rotating joint 62. The first adapter 82 can rotate in the limiting installation hole 621 of the first rotating joint 62. The second adapter 83 is used for limiting and clamping installation in the positioning installation hole 7331 of the second rotating joint 733, so that the second adapter 83 can rotate synchronously with the second rotating joint 733. The cleaning brush 81 outside the rotating shaft can effectively scrape and clean the inner wall of the air guide rail 5 and the installation baffle 3.

[0062] As shown in Figure 1 and Figure 13 :

[0063] The side of the sealing plate 9 is provided with a plurality of elastic blocking blocks 91 which are evenly distributed at equal intervals. The elastic blocking blocks 91 are each provided with a plurality of layers of sealing rings.

[0064] When the air guide rail 5 and the inner wall of the installed baffle 3 need to be cleaned, the air outlet hole 54 of the air guide rail 5 needs to be blocked in advance. The user corresponds the elastic plug block 91 on the blocking plate 9 with the air outlet hole 54 of the air guide rail 5 one by one, and presses the elastic plug block 91 into the inside of the air guide rail 5. The several layers of sealing rings on the elastic plug block 91 effectively increase the blocking effect and increase the friction force of installation, so that the elastic plug block 91 can be positioned and installed in the air outlet hole 54 of the air guide rail 5, effectively preventing the cleaning liquid from flowing out of the air outlet hole 54 of the air guide rail 5.

[0065] Specific working principle:

[0066] The air guide rail 5 and the installed baffle 3 of the self-cleaning air supply rail form an air duct. The inside of the freezer body 1 is used to store frozen goods. When refrigeration is needed, the evaporator 2 will produce cold air. When the air supply fan 42 rotates, the cold air will pass through the air inlet 32 of the installed baffle 3 and enter the air duct between the air guide rail 5 and the installed baffle 3. The air duct will deliver the cold air to the inside of the freezer to refrigerate the internal goods. After long-term use of the freezer, it needs to be regularly disinfected and cleaned to remove odors and bacteria inside the freezer. When cleaning, the user takes out the cold storage goods inside the freezer and uses a disinfecting cleaning liquid to clean the inner wall of the freezer to remove odors from the inner wall of the freezer. When cleaning the air duct, the user blocks the air outlet end of the air guide rail 5 with the blocking plate 9, so that the air guide rail 5 cannot circulate. At the same time, the sealing plug mechanism 43 of the air supply device 4 switches to block all the air inlets 411 of the air inlet rail 41 to prevent the cleaning liquid from flowing out, so that the air guide rail 5 and the installed baffle 3 are in a sealed state. The user then opens the addition port 521 on the sealing cover plate 52 to add cleaning liquid to the sealed air duct, so that the disinfecting cleaning liquid soaks the inner wall of the air guide rail 5 and the installed baffle 3. After the disinfecting cleaning liquid soaks the inner wall of the air guide rail 5 and the installed baffle 3 for a certain period of time, the lifting device 6 moves the rotating brush 8 up and down between the air guide rail 5 and the installed baffle 3. When the rotating brush 8 moves up and down, it drives the self-rotation guide mechanism 7 to move synchronously. When the self-rotation guide mechanism 7 moves, it drives the rotating brush 8 to rotate. When the rotating brush 8 rotates, it rubs and cleans the inner wall of the air guide rail 5 and the installed baffle 3. The rotating brush 8 and the cleaning liquid cooperate to effectively clean the inner wall of the air guide rail 5 and the installed baffle 3. After the inner wall of the air guide rail 5 and the installed baffle 3 is cleaned, the user opens the drain pipe 56 to drain the cleaning liquid. After the cleaning liquid is drained, the user removes the blocking plate 9. After the blocking plate 9 is removed, the air supply device 4 is simultaneously unsealed, and the air between the air guide rail 5 and the installed baffle 3 is circulated by rotating the air supply, so that the air duct between the air guide rail 5 and the installed baffle 3 is dried.

[0067] The above embodiments only express one or several embodiments of the present application, the description is more specific and detailed, but it cannot be understood as the limitation of the patent scope of the present application. It should be noted that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
