Description

Technical Field

[0001] The invention belongs to the technical field of refrigerators, and in particular relates to an odor-removing and disinfecting refrigerator. Background Art

[0002] Odor-removing and disinfecting refrigerators reduce the impact of bacterial growth and odor on food by removing odors and killing bacteria, thereby extending the shelf life of food and allowing food to maintain its original taste and nutritional components for a longer period of time; common odor-removing and disinfecting technologies include activated carbon adsorption technology, photocatalyst technology, plasma technology and silver ion antibacterial technology.

[0003] Among them, the invention patent with the authorization publication number CN110631308B provides a long-term odor-free and frost-resistant refrigerator, including a refrigerator body, a refrigerator door foam layer and a refrigerator refrigeration compartment; a long-term frost-resistant device is installed in the refrigerator door foam layer; the long-term frost-resistant device connects the outside of the refrigerator body with the inside of the refrigerator refrigeration compartment; the long-term frost-resistant device includes an air pressure balance device, a long-term frost-resistant box and an odor-free device. By installing a long-term frost-resistant device including an air pressure balance device, a long-term frost-resistant box and an odor-free device in the refrigerator door foam layer, frost and odor can be effectively prevented and odor-free; when the inside of the refrigerator refrigeration compartment is cooled, the pressure inside the refrigerator refrigeration compartment is reduced, the lightweight float is lifted, and the outside gas enters the refrigerator refrigeration compartment; during the process of gas entering the refrigerator refrigeration compartment, the frost-resistant material removes moisture from the outside gas, and removes odor through the odor-free adsorption material. This type of refrigerator mainly relies on adsorption of odor by adsorption materials. As the refrigerator is used for a long time, the adsorption capacity of the adsorption material will decrease, affecting the subsequent adsorption treatment effect. The adsorption material usually needs to be replaced regularly. The adsorption material inside the refrigerator is mostly embedded in the refrigerator body, and the surrounding sides of the body are mostly covered with a foam layer for insulation, which is not convenient to replace. At the same time, replacing the carbon plate will affect the refrigeration effect.

[0004] In addition, there is an invention patent with publication number CN117537545A that provides a sterilization device and a refrigerator, which mainly utilizes the Fenton reaction to generate a water solution with a sterilizing effect, and sprays the water solution into the storage compartment of the refrigerator through an atomizing component to sterilize, deodorize and moisturize the interior of the compartment, which can improve the preservation effect and preservation time of the food inside the refrigerator and avoid the strong odor inside the refrigerator; and by generating a water solution with a sterilizing effect and atomizing and spraying it into the storage compartment of the refrigerator, the probability of frost on the inner wall of the refrigerator will increase, and at the same time, the probability of moisture will increase for some dry foods; the atomized sprayed water solution will penetrate into the food stored inside the refrigerator, which may affect the safety of the food.

[0032] The following is combined with Figure 1-13 This application is further described in detail.

[0033] Please refer to Figure 1 , Figure 2 and Figure 3 A deodorizing and disinfecting refrigerator comprises a box body 1, a storage chamber is arranged inside the box body 1, and a storage rack 6 and a pull-out drawer 7 are arranged inside the storage chamber respectively; a door body 2 is hingedly arranged on the front side of the box body 1, and installation cavities are arranged on the top, bottom and left and right side walls of the box body 1, and a refrigeration system 3 is jointly arranged in the installation cavity located on the left and right side walls of the box body 1 and the bottom installation cavity, and a deodorizing circulation system 4 is arranged inside the top installation cavity of the box body 1, and an ozone generator is also arranged in the bottom installation cavity of the box body 1, and the ozone generator is connected with four air ducts 5, and the four air ducts 5 are distributed inside the installation cavities on the left and right sides of the box body 1, and the air ducts 5 pass through the installation cavities on the side walls of the box body 1 and are connected to the bottom installation cavity of the box body 1; a filter is installed at the outlet of the air duct 5; the filter prevents the air duct 5 from being blocked.

[0034] See also Figure 4and Figure 5 The left and right inner walls of the box body 1 are evenly provided with air holes 11 connected to the inside of the installation cavity of the side wall from top to bottom, and the air holes 11 are installed with air valve components 12; Figure 6 The side walls of the top mounting cavity of the box body 1 are evenly provided with air flow holes 13 connected with the side wall mounting cavity of the box body 1; an air valve assembly 12 is also arranged inside the air flow hole 13, and the installation direction of the air valve assembly 12 inside the air flow hole 13 is opposite to the installation direction of the air valve assembly 12 installed inside the air hole 11.

[0035] See also Figure 5 and Figure 6 The air valve assembly 12 includes an air guide column 121, a T-shaped hole 122 is arranged inside the air guide column 121, and filters are arranged at the three openings of the T-shaped hole 122 of the air guide column 121. The outer wall of the air guide column 121 is sleeved with a spring, the spring on the air valve assembly 12 inside the air flow hole 13 is connected to the hole wall of the air flow hole 13, and the spring on the air valve assembly 12 inside the air hole 11 is connected to the hole wall of the air hole 11. The cross-section of the air guide column 121 is T-shaped, and a sealing rubber ring is arranged between the horizontal section of the air guide column 121 and the corresponding hole wall.

[0036] The arranged air valve assembly 12 effectively ensures that the deodorizing circulation system 4 drives the one-way flow of the air flow inside the storage chamber when it is working. At the same time, when the air flow flows, it will force the air guide column 121 to move to extend the T-shaped hole 122 orifice from the inside of the air flow hole 13 and the inside of the air hole 11 respectively. The air hole 11 inside the storage chamber is more prone to breeding bacteria and accumulating pollutants. During the one-way circulation of gas, the air guide column 121 moves along the air hole 11 toward the inside of the storage chamber, which can effectively discharge the pollutants inside the air hole 11 to the outside of the air hole 11 for easy cleaning. At the same time, during the refrigeration process, the movement of the air guide column 121 can effectively prevent the orifice from being blocked by frost.

[0037] See also Figure 3 , Figure 6 , Fig. 9 as well as Fig.13The deodorizing circulation system 4 includes an isolation plate 41 arranged inside the top mounting chamber of the box body 1, the isolation plate 41 divides the top mounting chamber of the box body 1 into an upper gas treatment chamber 411 and a lower gas treatment chamber 412, and a baffle strip 42 is also arranged at the upper end of the isolation plate 41, the baffle strip 42 divides the upper gas treatment chamber 411 into two identical semi-isolated chambers in front and back, and two scroll fans 43 are arranged inside each semi-isolated chamber, the scroll fan 43 is used to pump the gas inside the storage chamber from the top of the box body 1 to the inside of the mounting chamber for circulation, and finally discharged to the storage chamber through the air hole 11 on the side wall of the box body 1, and an air duct 5 is distributed on the left and right inside each semi-isolated chamber; the isolation plate 41 can ensure that when the scroll fan 43 is working, the gas can only move in one direction from the lower gas treatment chamber 412 to the upper gas treatment chamber 411; the baffle strip 42 is arranged to ensure that the ozone exported through the air duct 5 in the later stage is evenly distributed during the sterilization process, thereby improving the sterilization effect.

[0038] See also Figure 7 , Figure 8 and Fig. 9 Two mounting grooves are symmetrically arranged on the inner wall of the lower gas treatment chamber 412, and a mounting frame 44 is detachably arranged inside the two mounting grooves. Carbon plate racks 45 are evenly arranged inside the mounting frame 44 by rotation, and an activated carbon plate 46 is clamped inside each carbon plate rack 45. A motor 47 is also arranged on the side wall of the mounting frame 44. Several carbon plate racks 45 are connected together by a pulley transmission, and one of the carbon plate racks 45 is fixedly connected to the output shaft of the motor 47.

[0039] When the gas inside the refrigerator circulates in one direction, the gas always contacts the lower side of the activated carbon plate 46 first. The activated carbon plate 46 is mainly made of activated carbon pressed into a plate with a certain thickness. After the lower side adsorbs the substance, it will be saturated first, resulting in reduced adsorption treatment efficiency. Regularly driving the carbon plate rack 45 through the motor 47 to drive the activated carbon plate 46 to flip 180 degrees is beneficial to improving the treatment efficiency of the activated carbon plate 46 for the gas.

[0040] See also Fig. 9 and Fig.11 The outer wall of the carbon plate rack 45 and the inner wall of the mounting frame 44 are both provided with fine and regularly arranged bristles, and the bristles are made of rubber material. When the carbon plate racks 45 at the left and right ends are horizontal, the bristles on the outer walls thereof and the bristles on the inner walls of the mounting frame 44 fit together to achieve sealing, and when two adjacent carbon plate racks 45 are horizontal, the bristles on the outer walls fit together; by setting the bristle seal, it can be ensured that the gas circulates through the activated carbon plate 46.

[0041] See also Fig. 9 and Fig.12A lamp rack 48 is provided on the lower end surface of the isolation plate 41, and lamp holders 481 are evenly arranged on the lamp rack 48. Two groups of front and rear UV sterilization lamps 482 are provided on the lamp holders 481. When the motor 47 drives the carbon plate rack 45 to flip 180 degrees, the bristles on the side wall of the carbon plate rack 45 will contact the outer wall of the lamp tube of the UV sterilization lamp 482, ensuring the light transmission effect when the UV sterilization lamp 482 is working.

[0042] After some pollutants are adsorbed on the activated carbon plate 46, the germs on its surface can be eliminated by the UV sterilization lamp 482, and the activated carbon plate 46 can be turned over regularly to sterilize both sides of the activated carbon plate 46 by the UV sterilization lamp 482; at the same time, it also fully ensures that during ozone sterilization, ozone can contact both sides of the activated carbon plate 46 to complete deep sterilization treatment.

[0043] See also Figure 4 , Fig. 9 and Fig.10 , an air intake baffle 49 is also provided at the lower end of the lower gas treatment chamber 412, an illuminating lamp is provided in the middle of the air intake baffle 49, and breeze guide holes 491 are evenly provided on the air intake baffle 49, and a filter plug 492 is provided inside each breeze guide hole 491 by means of clearance fit, and the structural shape of the filter plug 492 is a spherical structure at the lower end and a truncated cone stacked structure at the upper end; and the shape of the breeze guide hole 491 is the same as the structural shape of the filter plug 492, and the filter plug 492 is composed of a rubber structure shell and a bamboo fiber material filled in the shell. The bamboo fiber itself has natural antibacterial properties, and the "bamboo Kun" component contained in it has an inhibitory effect on common harmful bacteria such as Escherichia coli and Staphylococcus aureus, which can destroy the living conditions of bacteria and hinder their growth and reproduction, thereby reducing the odor caused by bacterial growth; the side wall of the spherical part of the shell is provided with an air intake hole, and the upper end of the truncated cone part of the shell is an open structure; and the spherical diameter of the shell is larger than the aperture of the air intake hole of the breeze guide hole 491.

[0044] See also Fig.13 In the process of gas circulation driven by the scroll fan 43, due to the clearance fit between the filter plug 492 and the breeze guide hole 491, the filter plug 492 will be sucked upward and fit the wall of the breeze guide hole 491 and then stop moving, and the gas passes through the air inlet hole of the shell and then passes through the bamboo fiber material into the lower gas treatment chamber 412 for subsequent treatment; when the scroll fan 43 stops working and the ozone generator produces ozone, the internal air pressure of the lower gas treatment chamber 412 is greater than the external air pressure, and the filter plug 492 will be pushed downward and fit the lower wall of the breeze guide hole 491 and then stop moving. At this time, the air inlet hole on the shell is blocked by the wall of the breeze guide hole 491, thereby preventing ozone leakage from contaminating food inside the refrigerator.

[0045] See also Figure 1A thermostat and sensors (including temperature sensor, humidity sensor, odor sensor, etc.) are arranged inside the box body 1, an operation panel is arranged on the outer wall of the door body 2, and the operation panel is electrically connected to the thermostat and the sensor; the thermostat and the sensor detect the environmental conditions inside the refrigerator in real time, and adjust the temperature inside the storage room through the operation panel.

[0046] See also Figure 5 , Figure 6 and Figure 8 The gas flow direction on the gas valve assembly 12 inside the air flow hole 13 is that the gas inside the upper gas processing chamber 411 is transported to the side wall mounting cavity of the box body 1, and the gas flow method on the gas valve assembly 12 inside the air hole 11 is that the gas inside the side wall mounting cavity of the box body 1 is transported to the storage chamber; the above-mentioned gas transportation method is a one-way circulation transportation, which effectively ensures that the gas in the storage chamber is disinfected and odor-free in turn, and then refrigerated by the refrigeration system 3, and finally discharged into the storage chamber.

[0047] See also Figure 3 and Figure 6 The number of air holes 13 corresponds to the number of air ducts 5, and a sealing baffle 141 is commonly provided between the one-to-one air holes 13 and the air ducts 5; the sealing baffle 141 is connected by a spring and is slidably arranged inside the box body 1 forward and backward, and the end of the sealing baffle 141 away from the spring is an inclined surface, and the inclined surface section of the sealing baffle 141 is arranged inside the air duct 5 and seals the pipe opening of the air duct 5, and the other end of the sealing baffle 141 cooperates with the air hole 13; when the ozone generator generates ozone gas and discharges it from the air duct 5, the air pressure inside the air duct 5 increases, which will push the sealing baffle 141 to slide and open the pipe opening of the air duct 5, and the sealing baffle 141 slides to close and seal the air hole 13; in order to ensure that the ozone generator can fully open the pipe opening of the air duct 5 when generating ozone and spraying it through the air duct 5, and push the sealing baffle 141 to slide to close the air hole 13, it can be sealed A magnetic sheet is provided at the end of the baffle 141 close to one end of the air flow hole 13, and a metal sheet is also provided at the air outlet position of the air flow hole 13. When ozone is discharged from the air duct 5, the internal air pressure increases and pushes the sealing baffle 141 to slide. The air flow hole 13 can be completely closed by the adsorption effect of the magnetic sheet and the metal sheet. When the ozone generator stops generating ozone, the inclined end of the sealing baffle 141 loses the air pressure effect, and at the same time the spring recovers to separate the magnetic sheet from the metal sheet, further closing the air duct 5. The provided sealing baffle 141 effectively isolates and seals the top mounting cavity of the box body 1, preventing ozone from escaping from the air flow hole 13 and leaking along the mounting cavity of the side wall of the box body 1 and the air hole 11 to the inside of the storage chamber and directly contacting the food. The isolated and sealed top mounting cavity allows the generated ozone to fully contact the activated carbon plate 46, thereby improving the treatment effect of the activated carbon plate 46.

[0048] When the present invention performs odor removal and disinfection in the storage room, first, the temperature inside the storage room is regulated by the operation panel, the refrigeration system 3 is turned on for refrigeration, and the scroll fan 43 is operated to realize one-way circulation of the gas inside the refrigerator. During the gas circulation process, the gas is sterilized and odor-removed in turn by three sterilization methods: adsorption by the activated carbon plate 46, irradiation by the UV sterilization lamp 482, and ozone generation by the ozone generator. In order to ensure the long-term adsorption effect of the activated carbon plate 46, the activated carbon plate 46 is regularly turned over to change the surface for adsorption. At the same time, after the surface is changed, the sterilization and odor removal effect of the UV sterilization lamp 482 and the ozone on the substances adsorbed by the activated carbon plate 46 is improved, and the adsorption function of the activated carbon plate 46 is restored.

[0049] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
