Description

Technical Field

[0001] The invention relates to the field of refrigeration devices, in particular to a refrigeration device with air purification. Background Art

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. The box contains a compressor, an ice maker, a cabinet or box for ice formation, and a storage box with a refrigeration device, which can provide a sufficiently constant low temperature environment for storing perishable items such as food. The interior of an existing refrigerator will frost after a period of use. The reasons for frost are usually as follows: When the humidity inside the refrigerator is high, water vapor in the air will condense into water droplets on the condenser and then frost. This is usually caused by frequent opening and closing of the refrigerator door, long-term door opening, or improper food storage. The condenser is a key component of refrigerator refrigeration. If the condenser fails, the refrigeration effect will decrease, causing the temperature inside the refrigerator to rise, thereby causing frost. If the refrigerator door is not sealed well, outside air will enter the refrigerator, causing the humidity to rise, thereby causing frost. The fan inside the refrigerator is responsible for circulating the air. If the fan fails, the air circulation is not smooth, the humidity will increase, and thus cause frost.

[0003] When storing food in an existing refrigerator, the volatility of the food itself will volatilize a certain amount of basic nitrogen and fat particles and other substances into the refrigerator and make the air inside the refrigerator turbid. When the food is stored for a long time, it is easy for different foods to have different flavors, resulting in a decrease in food quality, and it is easy to cause reactions between different volatile substances to form harmful gases, increasing the risk of food spoilage. In addition, after a period of use, dust collection structures such as dust collection nets will accumulate a large amount of dust and other impurities in the existing air purification equipment, which needs to be cleaned regularly. When washing the dust collection net, in order to prevent the electrode plate and other electronic equipment from being damaged by water, the user needs to manually remove the dust collection net, which is inconvenient to use. In addition, the existing refrigerator defrosting method is usually a heating method, and the melted water will carry some food residues and the like to flow down along the inner wall of the refrigerator and remain inside the refrigerator, which needs to be removed manually, thereby increasing the user's labor and causing a certain waste of water resources. The food residues carried in the melted water will further increase the degree of turbidity of the air in the refrigerator. Therefore, a refrigeration device with air purification is proposed. Summary of the invention

[0004] The technical problem to be solved by the present invention is that when storing food inside an existing refrigerator, the volatility of the food itself will volatilize a certain amount of substances such as basic nitrogen and fat particles into the refrigerator interior, making the air inside the refrigerator turbid. When food is stored for a long time, it is easy for different foods to have their flavors intermingled, resulting in a decline in food quality. Moreover, it is easy for reactions to occur between different volatile substances to form harmful gases, increasing the risk of food spoilage. After an existing air purification device has been used for some time, dust collection structures such as dust collection nets will accumulate a large amount of impurities such as dust and need to be cleaned regularly. When washing the dust collection net with water, in order to prevent electronic devices such as electrode plates from being damaged by water ingress, the user needs to manually remove the dust collection net, so it is not convenient to use. In addition, the existing defrosting method for refrigerators is usually a heating method. The melted water will carry some food residues and flow down along the inner wall of the refrigerator and stay inside the refrigerator, which needs to be manually removed, thus increasing the labor of the user and causing a certain amount of water resource waste. Moreover, the food residues carried by the melted water will further increase the turbidity of the air inside the refrigerator.

[0017] With the above technical solution, the controller drives the ultrasonic transducer, and the ultrasonic transducer performs high-frequency oscillation on the dust collecting net and the coarse filter net inside the air purification device, so that the dust collecting net and the coarse filter net are in full contact with water and a large number of bubbles are generated. The water vigorously flushes the dust collecting net and the coarse filter net, thereby removing impurities such as dust on the dust collecting net and the coarse filter net. Subsequently, the water after cleaning is discharged through the water outlet.

[0018] Preferably, the sealing device includes a sealing coil. The sealing coil is made of PVC plastic material. The bottom of the sealing coil is fixedly connected with a reel. The reel is rotatably connected to the inner wall of the air purification device. A second pulley is fixedly connected to the axis of the reel.

[0029] The following will clearly and completely describe the concept and technical effects generated by the present invention in combination with the embodiments to fully understand the purpose, features and effects of the present invention.

[0030] As shown in the attached Figure 1 figure, the present invention provides a refrigeration device with air purification. A defrosting heating plate 2 is installed at the top of the inner wall of the main body 1 of the refrigerated cabinet. A water collection device 4 is arranged at the bottom of the inner wall of the main body 1 of the refrigerated cabinet. An air purification device 3 is arranged on the side of the water collection device 4. The horizontal height of the top surface of the air purification device 3 is higher than the horizontal height of the top surface of the water collection device 4. Inside the air purification device 3, there are successively a coarse filter screen 31, an electrode plate 32 and a dust collection net 33. Sealing devices 6 are arranged on both sides of the electrode plate 32. A diversion device 5 is arranged inside the water collection device 4. A disinfection device 7 is arranged inside the water collection device 4. A controller is installed outside the main body 1 of the refrigerated cabinet.

[0031] In the above embodiment, when too much frost accumulates inside the main body of the refrigerated cabinet, the controller starts the defrosting heating plate 2. The defrosting heating plate 2 raises the temperature inside the main body 1 of the refrigerated cabinet and melts the frost, thereby completing the defrosting work and avoiding the reduction of the refrigeration effect caused by excessive frosting inside the main body 1 of the refrigerated cabinet.

[0032] As shown in the attached Figure 2 and attached Figure 6As shown in the figure, the water collection device 4 includes a water collection box 41, which is installed at the bottom of the inner wall of the refrigeration cabinet main body 1. On the left and right sides of the inner wall of the water collection box 41, there are movably connected movable sealing plates 42. The movable sealing plates 42 are composed of multiple rigid plates and rubber soft plates fixedly connected between every two adjacent rigid plates. On both sides of the rigid plates on the opposite surfaces of the two movable sealing plates 42, there are fixedly connected active sliders 48. On both sides of the remaining movable sealing plates 42, there are fixedly connected passive sliders 49. On the front and back sides of the inner wall of the water collection box 41, there are provided chutes. The active sliders 48 and the passive sliders 49 have the same thickness, and the active sliders 48 and the passive sliders 49 on the same side are movably connected in the same chute. On the side of the active slider 48, there is fixedly connected a nut 43. Inside the refrigeration cabinet main body 1, there is installed an electric double-headed lead screw 44. The two nuts 43 are respectively threadedly connected to the two ends of the electric double-headed lead screw 44. On the top of the water collection box 41, there is installed a filter screen, and the horizontal height of the filter screen is the same as that of the bottom of the inner wall of the refrigeration cabinet main body 1. On the opposite surfaces of the two movable sealing plates 42, there are fixedly connected rubber edge strips. On the opposite surfaces of the two rubber edge strips, there are provided fitting card slots. Inside the filter head 52, there is installed an activated carbon filter layer. The filter head 52 is inserted into the inside of the air purification device 3. The diversion device 5 includes a pipe 51. The two ends of the pipe 51 are respectively connected to the water collection box 41 and the air purification device 3, and the horizontal height of the end of the pipe 51 inserted into the air purification device 3 is lower than the horizontal height of the end of the pipe 51 inserted into the water collection box 41. At the end of the pipe 51 inserted into the air purification device 3, there is installed a filter head 52. At the end of the pipe 51 close to the water collection box 41, there is installed a check valve 53. The valve plate of the check valve 53 is fixedly connected with a valve plate rotating shaft 531. The top end of the valve plate rotating shaft 531 penetrates to the outside of the check valve 53 and is fixedly connected with a gear one 532. On the side of the right nut 43, there is fixedly connected a rack 45. The rack 45 is meshed with the gear one 532.

[0033] In the above embodiment, the controller drives the electric double-headed lead screw 44 to rotate. The electric double-headed lead screw 44 drives the two nuts 43 to move towards each other simultaneously. The two nuts 43 respectively drive the two active sliders 48 to move towards each other. The two active sliders 48 respectively drive the two movable sealing plates 42 to move towards each other. As the movable sealing plates 42 gradually open, the movable sealing plates 42 drive the passive sliders 49 to move until the water collection box 41 is closed, thereby sealing the water collection box 41. The filter screen intercepts large food residues, thereby preventing large food residues from entering the interior of the water collection box 41. When the two movable sealing plates 42 are closed, they are connected between the two rubber edging strips. The elasticity of the rubber material itself seals the gap between the two movable sealing plates 42, thereby enhancing the sealing performance. The right nut 43 drives the rack 45 to move. The rack 45 drives the first gear 532 to rotate. The first gear 532 drives the valve plate rotating shaft 531 to rotate. The valve plate rotating shaft 531 drives the valve plate to rotate until it opens, so that the water in the water collection box 41 flows into the interior of the air purification device 3 due to the height difference at both ends of the pipeline 51.

[0034] As shown in the attached Figure 3 figure, inside the air purification device 3, there are successively a coarse filter screen 31, electrode plates 32, and a dust collection net 33.

[0035] In the above embodiment, the air inside the refrigeration cabinet main body 1 enters the interior of the air purification device 3 through the air inlet. It is preliminarily filtered by the coarse filter screen 31. At the same time, the electrode plates 32 are activated and release static particles. The static particles adsorb the particles in the air. The adsorbed particles are collected by the dust collection net 33. Subsequently, the purified air is discharged through the air outlet driven by the air flow suction machine, thereby completing the purification of the air inside the refrigeration cabinet main body 1 and preventing the dirty air volatilized from the stored food inside the refrigeration cabinet main body 1 from polluting the interior of the refrigeration cabinet main body 1.

[0036] As shown in the attached Figure 4 、 attached Figure 7 and attached Figure 8As shown, the sealing device 6 includes a sealing coil 61. The sealing coil 61 is made of PVC plastic.

The far sides of the two winding rods 65 are rotatably connected to the inner wall of the waterproof casing. The outer wall of the connecting rope 63 penetrates below the waterproof casing and is movably connected therebetween. Plastic edging strips are fixedly connected to both sides of the sealing coil 61. The plastic edging strips are made of PVC plastic. The plastic edging strips are movably connected to the inside of the guide rails 64.

[0037] In the above embodiment, the single-row pulley 46 drives the double-row pulley 47 to rotate through the synchronous belt.

The winding rod 65 drives the connecting rope 63 to gradually tighten. The connecting rope 63 drives the side rod 62 to rise. The side rod 62 drives the sealing coil 61 to rise until the outside of the electrode plate 32 is sealed, thereby preventing water from damaging the electrode plate 32 when cleaning the inside of the air purification device 3. The plastic edging strips always move along the inside of the guide rails 64, thereby enhancing the sealing effect of the sealing coil 61 and preventing the sealing coil 61 from derailing and failing to seal the outside of the electrode plate 32.

[0038] As attached Figure 5As shown in the figure, the disinfection device 7 includes a disinfectant spray pipe 71.

The second gear 73 drives the rotating shaft to rotate. The rotating shaft drives the sealing plug 72 to rotate until it is opened, so as to spray the disinfectant into the inside of the water collection box 41, and disinfect the accumulated water in the water collection box 41 through the disinfectant.

[0040] Working principle: When the refrigerator cabinet main body 1 is running, the user starts the controller. The controller starts the air suction machine and the electrode plate 32. The air suction machine sucks the air inside the refrigerator cabinet into the air inlet. The electrode plate 32 releases static particles to adsorb the particles in the air. During the process, the particles stay on the dust collection net 33. The purified air is discharged into the inside of the refrigerator cabinet main body 1 through the air outlet.

[0041] When defrosting the inside of the refrigerator cabinet main body 1, the user starts the controller. The controller drives the defrosting heating plate 2. The defrosting heating plate 2 heats the inside of the refrigerator cabinet main body 1, so that the melted frost water flows into the inside of the water collection box 41, and then the controller turns off the defrosting heating plate 2.

[0042] When self-cleaning the inside of the air purification device 3, the user starts the controller, turns off the purification function of the air purification device 3, and then the controller drives the electric double-headed lead screw 44. The electric double-headed lead screw 44 drives the two nuts 43 and the rack 45 to move towards each other simultaneously and drives the single-row pulley 46 to rotate at the same time. The two nuts 43 drive the two active sliders 48 to move towards each other respectively. The two active sliders 48 drive the two movable sealing plates 42 to move towards each other respectively. The movable sealing plate 42 drives the passive slider 49 to move until the movable sealing plate 42 unfolds to close the water collection box 41.

[0043] At the same time, the passive slider 49 drives the toothed plate 74 to move. The toothed plate 74 drives the second gear 73 to rotate. The second gear 73 drives the rotating shaft to rotate. The rotating shaft drives the sealing plug 72 to rotate until it is opened, so that the disinfectant flows into the inside of the water collection box 41 and mixes with the accumulated water in the water collection box 41. At this time, the water collection box 41 is in a closed state.

[0044] The rack 45 drives the first gear 532 to rotate, and the first gear 532 drives the valve plate rotating shaft 531 to rotate until the check valve 53 is opened, so that the mixture of water and disinfectant in the water collection box 41 flows into the interior of the air purification device 3.

[0045] The single-row pulley 46 drives the double-row pulley 47 to rotate through the synchronous belt. The double-row pulley 47 drives the connecting rotating shaft and the winding rod 65 on the front side to rotate. At the same time, the double-row pulley 47 drives the transmission pulley to rotate through the belt. The transmission pulley drives the connecting rotating shaft and the winding rod 65 on the rear side to rotate. The winding rod 65 drives the first pulley 66 to rotate. The first pulley 66 drives the second pulley 67 to rotate through the transmission belt. The second pulley 67 drives the reel 68 to rotate. The winding rod 65 drives the connecting rope 63 to gradually tighten. The connecting rope 63 drives the side rod 62 to rise. The side rod 62 drives the sealing coil 61 to rise until the outside of the electrode plate 32 is sealed.

[0046] Subsequently, the controller starts the ultrasonic transducer. The ultrasonic transducer performs high-frequency oscillation on the dust collection net 33 and the coarse filter net 31 inside the air purification device 3, so that the dust collection net 33 and the coarse filter net 31 are in full contact with water and a large number of bubbles are generated. The water vigorously flushes the dust collection net 33 and the coarse filter net 31. At the same time, the water cleans the filter head 52 until the filter head 52, the dust collection net 33 and the coarse filter net 31 are cleaned.

[0047] After the cleaning is completed, the controller starts the electric double-headed lead screw 44 to reverse, and resets the sealing coil 61, the movable sealing plate 42, the check valve 53 and the sealing plug 72 through the above operations in the opposite direction.
