Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a household appliance odor removal and sterilization module and a refrigerator. Background Art

[0002] At present, refrigerators have become essential household appliances in people's daily lives. With the continuous improvement of people's living standards and the further improvement of health concepts, people have higher and higher requirements for the air quality in refrigerators.

[0003] Although the low temperature in the refrigerator can inhibit the growth of room-temperature bacteria, for some cold-loving pathogens such as Escherichia coli, Staphylococcus aureus and other bacteria, the low temperature environment of 0-10 degrees Celsius in the refrigerator is still a breeding ground for their growth and reproduction. These bacteria will produce odorous gases such as methane, hydrogen sulfide, methyl mercaptan, methylamine and other odorous gases during their growth and metabolism. The longer the time, the stronger the gas emitted. The mixture of multiple gases will make the refrigerator produce a more unpleasant odor.

[0004] Various raw and cooked foods are stored directly in the refrigerator without being disinfected and sterilized. The mutual contamination of meat and vegetables, raw and cooked foods in the closed space is a factor that causes the spread of refrigerator germs. "Diseases come from the mouth", and people will affect their health if they eat foods contaminated by bacteria.

[0005] In summary, the odor in the refrigerator is most likely caused by food spoilage, which leads to an increase in bacteria and can have a serious impact on people's health, so the odor must be removed as soon as possible. Summary of the Invention

DETAILED DESCRIPTION

[0052] The present invention will be described in further detail below in conjunction with the accompanying drawings. The above-mentioned and other purposes, features, aspects and advantages of the present invention will become more apparent so that those skilled in the art can implement them with reference to the text of the specification. In the accompanying drawings, for the sake of clarity, shapes and sizes may be exaggerated, and the same reference numerals will be used in all figures to indicate the same or similar parts. In the following description, words such as center, thickness, height, length, front, back, rear, left, right, top, bottom, top, bottom, etc. are based on the orientation or positional relationship shown in the accompanying drawings. In particular, "height" is equivalent to the size from top to bottom, "width" is equivalent to the size from left to right, and "depth" is equivalent to the size from front to back. These relative terms are for the sake of convenience of explanation and are generally not intended to require a specific orientation. Terms related to attachment, connection, etc. (e.g., "connection" and "attachment") refer to the relationship between these structures that are directly or indirectly fixed or attached to each other through an intermediate structure, as well as movable or rigid attachment or relationship, unless otherwise explicitly stated.

[0053] Next, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the terms "having," "including," and "comprising" used herein do not imply the presence or addition of one or more other elements or combinations thereof.

[0054] like Figures 1-16 As shown, the present invention provides a household appliance odor removal and sterilization module 10, comprising a first shell 12 and a second shell 11. After the first shell 12 and the second shell 11 are installed, an air duct is formed between the two; a odor removal and sterilization component and a fan component are provided in the air duct; the odor removal and sterilization module is also integrated with a light source component 13, which is detachably installed on the first shell 12; wherein, the air duct and the light source component 13 are independently arranged, and the distance between the light source component 13 and the household appliance door body is smaller than the distance between the air duct and the household appliance door body, that is, when the refrigerator is opened, the light source component 13 is closer to the user relative to the air duct, so as to improve the lighting effect and at the same time will not affect the sterilization efficiency when the refrigerator door is opened.

[0055] The odor removal and sterilization assembly includes an odor removal element 15, an ion generator 16, and a fan assembly, which are sequentially arranged in the air duct and are located on the same straight line.

[0056] The fan assembly includes a fan 17. A fan cover is provided outside the fan 17. The fan cover is provided with a fan air inlet and a fan air outlet. The fan air inlet is isolated from the fan air outlet.

[0057] The air duct is located between the second housing 11 and the first housing 12 of the household appliance deodorizing and sterilizing module 10. The upper half of the air duct is located in the first housing 12, and the lower half is located in the second housing 11. Alternatively, after the first housing 12 is installed in the second housing 11, the passage between the first and second housings 12, 11 forms the air duct, that is, one side wall of the air duct is the first housing 12, and the other side wall is the second housing 11.

[0058] Specifically, after the first shell 12 and the second shell 11 are installed, at least two flush areas are formed between the two, and the two areas are independent of each other and do not overlap. The air duct and the light source assembly 13 are respectively located in the two independent areas. Figure 6 The two areas are the air duct area E' and the light source area E. The air duct area E' and the light source area E are independent of each other and do not overlap. The two areas are separated by a baffle 116 to form independent installation areas for the light source component 13 in the cover plane and the sterilization component in the air duct.

[0059] The cover plane is Figure 9 The plane in the middle horizontal direction is specifically the plane where the upper end surface 122 is located, that is, the light source assembly 13 and the sterilization assembly are located in two independent areas flush with the upper end surface 122, rather than overlapping in the height direction of the first shell 12, so as to reduce the thickness of the cover.

[0060] The baffle 116 may be provided with a wiring hole or wiring groove 1161 that allows wiring to pass through. In this embodiment, the wiring hole or wiring groove 1161 allows wiring for the light source assembly 13 or ion generator 16 to pass through. The air duct is located within the air duct area, and the light source assembly 13 is located within the light source area, allowing the air duct and light source assembly 13 to be independently arranged. The power wiring for the ion generator 16 and fan assembly within the air duct is connected to the main control board 192 from the light source area E. That is, the power wiring for the ion generator 16 and fan assembly is connected to the main control board 192 from below the light source assembly 13. This prevents the wiring and light source assembly 13 from coming into contact with the moist air within the air duct, which could affect the service life of the light source assembly 13. Furthermore, the air duct and light source assembly 13 are located in two flush areas, which does not increase the overall thickness of the odor-eliminating and sterilization module.

[0061] The air duct is provided with an air inlet channel 112 and an air outlet channel 113. The angle between the air inlet channel 112 and the air outlet channel 113 is an obtuse angle or a right angle. The air inlet channel 112 and the air outlet channel 113 are formed by assembling the first shell 12 and the second shell 11.

[0062] Air inlet duct 112 is located on one side of odor removal element 15, and air outlet duct 113 is located on one side of fan 17. Air from the refrigerator enters the duct through air inlet duct 112, passes through odor removal element 15, ion generator 16, and fan 17 in sequence, and is then deodorized and sterilized by fan 17 before being discharged from air outlet duct 113 back into the refrigerator.

[0063] The angle between the air inlet channel 112 and the air outlet channel 113 is an obtuse angle or a right angle. It can be understood that the air inlet channel 112 and the air outlet channel 113 can be regarded as two straight channels, and the angle between the straight line where the air inlet channel 112 is located and the straight line where the air outlet channel 113 is located is an obtuse angle or a right angle. This design can improve the air circulation efficiency. It can also be understood that the air inlet channel 112 and the air outlet channel 113 are located at two ends that are relatively far apart on the odor removal and sterilization module, which increases the circulation length of the air in the air duct. After the air enters the air inlet channel 112, the flow path discharged from the air outlet channel 113 after passing through the odor removal component 15, the ion generator 16, and the fan 17 is a straight line, or the flow path is a curve with an obtuse angle.

[0064] The air outlet channel 113 includes a first air outlet channel 1131 and a second air outlet channel 1132. The first and second air outlet channels 1131, 1132 may be provided with a partition, or may not be provided with a partition. The first and second air outlet channels 1131, 1132 are connected to the fan outlet. The first and second air outlet channels 1131, 1132 are connected to the two sides of the odor removal and sterilization module.

[0065] The reason why two air outlet channels are provided in this embodiment is that a fan with higher power is used. Providing two air outlet channels at the fan outlet can increase the air outlet area.

[0066] refer to Figure 5 The first housing 12 or the second housing 11 is provided with an air inlet 1212 and an air outlet 1213. The air inlet 1212 and the air outlet 1213 are located on different sides of the first housing 12, or on different sides of the second housing 11. That is, the air inlet and the air outlet can be provided on both the first housing or both the second housing; or the air inlet can be provided on the first housing or the second housing, and all the air outlets can be provided on the second housing; or the air inlet can be provided on the first housing or the second housing, and the air outlets can be provided on both the first housing and the second housing; or the air inlet can be provided on both the first housing and the second housing, and all the air outlets can be provided on the first housing or the second housing.

[0067] The first housing 12 includes four first housing walls 121 and an upper end surface 122. The first housing walls 121 and upper end surface 122 respectively constitute the side walls and end surface of the first housing 12. In this embodiment, the light source assembly 13 is removably mounted on the upper end surface 122, which faces away from the embedded box 20. The air inlet 1212 and the air outlet 1213 are located on different first housing walls 121. Preferably, the air inlet 1212 and the air outlet 1213 are located on two first housing walls 121 that are farther apart.

[0068] It can be understood that the first housing wall 121 is designed to be hollowed out or partially hollowed out. To facilitate the sequential passage of air through the odor-purifying element 15, ionizer 16, and fan 17, the air inlet 1212 and air outlet 1213 are respectively disposed on the two side walls of the household appliance odor-purifying and sterilization module 10, i.e., in the hollowed-out areas of the first housing wall 121. After the first housing 12 is mounted on the second housing 11, the air inlet and air outlet formed in the hollowed-out areas of the first housing wall 121 correspond to the air inlet channel 112 and the air outlet channel 113.

[0069] The second shell 11 is provided with a protrusion 111 facing the embedded box 20 . The protrusion 111 is arranged toward the embedded box 20 . A mixing space for ions and airflow is formed between the protrusion 111 and the ion generator 16 .

[0070] A first air guide plate 181 , a second air guide plate 182 , and a sealing plate 183 are provided in the air duct.

[0071] refer to Figure 5-Figure 8 , the first air guide plate 181 is used to guide the air to the position of the ion generator 16. The first air guide plate 181 is located on the protrusion 111 of the household appliance odor purification and sterilization module 10, or the first air guide plate 181 is a part of the protrusion 111. The protrusion 111 is located on the second shell 11, or the protrusion 111 is a part of the second shell 11. Therefore, the first air guide plate 181 is located on the second shell 11, or is a part of the second shell 11. Preferably, the inclined portion on the protrusion 111 serves as the first air guide plate 181, that is, the first air guide plate 181 is inclined, and the air is guided to the ion release end face of the ion generator 16. The odor purification component 15 is provided at one end of the first air guide plate 181, and the other end corresponds to the position of the ion generator 16.

[0072] Specifically, the working principle of the ion generator 16 is to ionize and decompose air molecules into positive ions and negative ions, thereby inactivating the floating bacteria and attached bacteria in the air and turning them into fresh and clean gas. In order not to increase the thickness of the entire odor-purifying and sterilizing module, the negative ion release end of the ion generator 16 is arranged toward the second shell 11. The second shell 11 is provided with a protrusion 111. The corresponding position of the protrusion 111 is provided with a first air guide plate 181 or a portion of the second shell 11 forms an inclined first air guide plate 181, that is, the ion release end face of the ion generator 16 faces the first air guide plate 181. After the air is deodorized by the odor-purifying component 15, it flows through the area between the first air guide plate 181 and the ion release end of the ion generator 16 under the action of the inclined first air guide plate 181, so that the ions are fully mixed with the air. The air molecules all pass through the entire negative ion release end face of the ion generator 16, inactivating the floating bacteria and attached bacteria in the air and turning them into fresh and clean gas. The inclined design of the first air guide plate 181 increases the volume of air that can flow per unit time at the negative ion release end of the ion generator 16, thereby improving the sterilization efficiency of the ion generator 16; while at the same time, it does not increase the thickness of other positions.

[0073] In order to reduce the thickness of the entire odor-removing and sterilizing module, the protrusion 111 is located in the direction of the second shell 11 toward the embedded box 20, and the protrusion 111 becomes a part of the second shell 11; the protrusion 111 is used to accommodate the channels around the ion generator 16 and the fan 17. In order to increase the sterilization efficiency of the ion generator 16, the ion release end face of the ion generator 16 is set toward the protrusion 111, and the inclined portion (side wall) of the protrusion 111 serves as the first air guide plate 181 to introduce air into the ion release end face of the ion generator 16; in order to reduce the volume of the household appliance odor-removing and sterilizing module 10, only the ion release end face of the ion generator 16 and the fan 17 are located in the protrusion 111, without increasing the thickness of other parts. The inclined design of the protrusion 111 and the first air guide plate 181 allows each air molecule to pass through the entire ion release end face, which can fully mix the ions and air and improve the sterilization efficiency. The second air guide plate 182 is used to introduce the air sterilized by the ion generator 16 into the fan assembly and discharge it; the second air guide plate 182 is located between the ion generator 16 and the fan assembly.

[0074] It can be understood that the second air guide plate 182 is located at the end of the first air guide plate 181. After the air is introduced into the ion release end of the ion generator 16 through the first air guide plate 181, it is then drained to the fan 17 through the second air guide plate 182. That is, under the action of the fan 17, the air continuously passes through the deodorizing element 15 and the ion generator 16.

[0075] The second air guide plate 182 includes an air guide top portion 1822 and an air guide side portion 1821. To reduce wind resistance, the cross-section of the air guide top portion 1822 of the second air guide plate 182 is configured as an arc surface. The air guide side portion 1821 is closely attached to the air duct, and the air guide side portion 1821 and the air guide top portion 1822 are integrally formed or sealed together. After the air guide side portion 1821 and the air guide top portion 1822 are integrally formed or sealed together, end openings are formed on each end surface, facing the ion generator 16 and the fan 17, respectively. Preferably, the end opening of the second air guide plate 182 facing the ion generator 16 is larger than the end opening of the second air guide plate 182 facing the fan 17, to ensure that all air is sterilized by the ion generator 16 before being directed into the fan 17, thereby improving the operating efficiency of the fan 17. The end opening of the second air guide plate 182 facing the fan 17 is connected to the fan inlet of the fan 17.

[0076] A sealing plate 183 surrounds the fan assembly to direct air into the assembly. This separates the fan inlet from the fan outlet of the fan 17. In this embodiment, the upper and lower ends of the sealing plate 183 abut the first housing 12 and the second housing 11 of the odor-removing and sterilizing module, respectively.

[0077] refer to Figures 9-12 The light source assembly 13 includes a light source 131 and a lampshade 132 . The lampshade 132 is provided with a clamping piece, which forms a limiting structure of the light source 131 and clamps the light source 131 to the lampshade 132 .

[0078] The first housing 12 is provided with a light source clamping portion 1222 of the light source assembly 13. The upper end surface 122 is provided with an installation area 1221, and the light source assembly 13 is located in the installation area 1221. The light source clamping portion 1222 is located around the installation area 1221 for clamping the light source assembly 13 to achieve detachable installation of the light source assembly 13.

[0079] Light source 131 is a surface light source, located on the end face of the appliance odor-removing and sterilizing module 10. Specifically, light source 131 is located on the upper end face 122 of the first housing 12 of the odor-removing and sterilizing module 10. Preferably, light source 131 emits visible light with a wavelength of 400-700 nanometers, illuminating the interior of the appliance while simulating plant photosynthesis. Preferably, the wavelength is 435-450 nanometers. Blue light within this wavelength range is effective in killing bacteria on target objects, thus purifying the environment.

[0080] The lampshade 132 further includes a clip and a panel 1321 . The panel 1321 is positioned opposite to the light source 131 . The clip and the panel 1321 are integrally formed, or the clip is fixedly connected to the panel 1321 .

[0081] Panel 1321 is a transparent panel, or lampshade 132 is a transparent lampshade. That is, when the entire lampshade 132 is designed to be transparent, panel 1321 and the clip are made of the same material. For structural stability, panel 1321 and the clip can be integrally formed. When only panel 1321 is a transparent panel, the clip is fixedly connected to panel 1321.

[0082] Preferably, the clamping member includes a first clamping portion 1322 and a second clamping portion 1323 , and the first clamping portion 1322 and the second clamping portion 1323 respectively restrict the movement of the light source 131 in the longitudinal direction and the transverse direction.

[0083] The first engaging portion 1322 and the second engaging portion 1323 may have the same engaging structure or different engaging structures. To facilitate engagement, in this embodiment, the first engaging portion 1322 is designed as a resisting structure that resists the light source 131 , and the second engaging portion 1323 is designed as a protruding structure that engages the light source 131 .

[0084] Specifically, the first engaging portion 1322 is integrally formed with or connected to the panel 1321. The first engaging portion 1322 is a thin plate structure that contacts the light source 131. The first engaging portion 1322 is visually formed by bending the panel 1321. The second engaging portion 1323 is a engaging protrusion, and the protrusion 13231 on the second engaging portion 1323 is positioned toward the light source 131. The second engaging portion 1323 is integrally formed with or connected to the panel 1321.

[0085] The light source assembly 13 further includes a contact piece 133 . The contact piece 133 is located between the light source 131 and the clamping piece. Pulling the contact piece 133 facilitates disassembly of the light source 131 .

[0086] In this embodiment, the abutment member 133 is located at the end of the light source 131, abutting the light source 131 and the second engaging portion 1323. It can be understood that the abutment member 133 is installed in the gap between the light source 131 and the second engaging portion 1323. On the one hand, the abutment member 133 abuts the light source 131, preventing it from shaking; on the other hand, pulling out the abutment member 133 facilitates the removal of the light source 131.

[0087] Specifically, the abutment member 133 includes a first bent section 1331, a second bent section 1332, and a protruding section 1333. The first bent section 1331 is located between the light source 131 and the engaging member; the second bent section 1332 is in close contact with the light source 131; and the protruding section 1333 is located between the first bent section 1331 and the second bent section 1332, with the protruding section 1333 being higher than the second bent section 1332. The first bent section 1331, the protruding section 1333, and the second bent section 1332 are sequentially connected or integrally formed.

[0088] It can be understood that the first bent section 1331 abuts against the light source 131 and the second clamping portion 1323 respectively, and under the limitation of the second clamping portion 1323, the second bent section 1332 is pressed against the light source 131. The convex portion 13231 of the second clamping portion 1323 abuts against the protruding section 1333. The two ends of the protruding section 1333 are connected or integrally formed with the first bent section 1331 and the second bent section 1332, and the protruding section 1333 is higher than the first bent section 1331 and the second bent section 1332, which facilitates pulling out the abutting member 133 from between the light source 131 and the convex portion 13231 of the second clamping portion 1323, and then moving the light source 131 to disengage it from the clamping of the second clamping portion 1323.

[0089] Preferably, the gap between the light source 131 and the second clamping portion 1323, that is, the thickness of the first bent section 1331 is not less than the width of the convex portion 13231 of the second clamping portion 1323, so that after pulling out the abutting member 133, moving the light source 131 can disengage it from the limitation of the convex portion 13231. By adding the abutting member 133, the integrity of the light source 131 is ensured during disassembly, and the overall disassembly and installation process is convenient and fast.

[0090] Reference Figure 11 , the protruding section 1333 includes a horizontal section and a vertical section. The horizontal section connects the first bent section 1331 and the vertical section to form a receiving cavity, and the cross-section of the receiving cavity is in a "冂" structure. The wires of the light source 131 can be accommodated in the protruding section 1333.

[0094] The transverse limiter includes a limit rib 124 and a limit block 125. The limit rib 124 contacts the end of the control board. The limit block 125 and the limit rib 124 form a limit slot, restricting the forward, backward, left, and right movement of the key control board 191. In this disclosure, the terms forward, backward, left, right, and up and down refer to the directions of the key control board 191 in three planes.

[0095] There are two limiting ribs 124, which are arranged opposite to each other and respectively contact the two ends of the key control plate 191 to limit the left and right movement of the key control plate 191. The cross-section of the limiting rib 124 is L-shaped. Specifically, the limiting rib 124 includes a first limiting portion 1241 and a second limiting portion 1242. The first limiting portion 1241 and the second limiting portion 1242 are integrally formed or fixedly connected to form an L-shaped limiting rib 124. The first limiting portion 1241 and the second limiting portion 1242 respectively contact the two side surfaces of the end of the key control plate 191, that is, they respectively contact the end face and side surface of the key control plate 191.

[0096] The limit block 125 is positioned opposite the second limit portion 1242. The key control panel 191 is accommodated between the limit block 125 and the second limit portion 1242, limiting the forward and backward movement of the key control panel 191. The distance between the limit block 125 and the second limit portion 1242 is exactly equal to the thickness of the key control panel 191. There are two limit blocks 125, one at each end of the key control panel 191.

[0097] In this embodiment, the transverse limiting member is located in the first shell 12 of the household appliance odor purification and sterilization module 10 and can be integrally injection-molded with the first shell 12 .

In this embodiment, the longitudinal limiter is located in the second housing 11 of the odor removal and sterilization module 10 and can be integrally injection molded with the second housing 11.

[0099] During installation, the key control panel 191 is first installed between the limiting ribs 124 and the limiting blocks 125, thereby limiting the movement of the control panel 191 on a flat surface. After the second housing 11 is installed with the first housing 12, the limiting posts 114 on the second housing 11 contact the top of the key control panel 191, thereby limiting the vertical movement of the key control panel 191. After the first housing 12 and the second housing 11 are disassembled, the limiting posts 114 no longer contact the key control panel 191, allowing the control panel 191 to be removed from between the limiting ribs 124 and the limiting blocks 125, allowing replacement or repair of the key control panel 191.

[0100] The key control panel 191 includes an indicator light. The first housing 12 is provided with a light-transmitting hole 1211 corresponding to the position of the indicator light.

[0101] A main control board 192 is located between the first and second housings 12, 11. This board is electrically connected to the odor-removing and sterilizing components, the fan assembly, and the key control board 191. This board is connected to the refrigerator's control panel for power and communication. All functions can be controlled via a mobile app, and the progress of the one-touch odor-removing mode can be displayed. For large-screen refrigerators, the large screen will display a mode switch for the sterilization module and simultaneously display the progress of the one-touch odor-removing mode.

[0102] The keypad 191 has two buttons, "One-touch Odor Removal" and "Intelligent Freshness Preservation," and two breathing indicator lights. "One-touch Odor Removal" corresponds to a first-color LED breathing light, while "Intelligent Freshness Preservation" corresponds to a second-color LED breathing light. Touching the "Intelligent Freshness Preservation" button activates the intelligent freshness preservation function, with the corresponding second-color LED breathing light. The ion generator and fan also start simultaneously and operate periodically. Touching the "One-touch Odor Removal" button activates the one-touch odor removal function, with the corresponding first-color LED breathing light. The ion generator and fan also start simultaneously and, after a period of operation, automatically switch to the intelligent freshness preservation mode.
