Description

Technical Field

[0001] This invention relates to the field of pull-out basket technology, and in particular to a disinfection structure for a pull-out basket. Background Technology

[0002] Currently, pull-out baskets are widely used as an efficient internal storage component for kitchen cabinets. Their drawer-style structure makes full use of the cabinet's depth, significantly improving the storage and retrieval efficiency of kitchen utensils. In existing designs, to facilitate the categorized storage and daily disinfection of dishes, cutlery, chopsticks, spoons, and other small tableware, a double- or multi-layer layout is typically used: dishes are stored in the middle drawer of the pull-out basket, while a dedicated, upward-facing box is fixedly installed inside the cabinet door for hanging or placing cutlery such as cutlery. Correspondingly, the accompanying disinfection structure generally includes a disinfection unit fixedly installed on the back panel or side panels of the middle drawer, and a horizontal disinfection outlet on this unit for irradiating and disinfecting dishes.

[0003] However, the existing pull-out basket sterilization structure still has shortcomings in practical use. Specifically, since the sterilizer body and its horizontal sterilization outlet are directly located inside the middle drawer, this structure significantly encroaches on the effective space used for storing dishes. This not only reduces the storage capacity but also easily interferes with the operation of taking and putting away dishes, reducing the convenience of use. In addition, the sterilizer body is installed on the side of the drawer with its sterilization outlet facing horizontally, while the fixed box for storing knives, forks, chopsticks, and spoons is installed inside the cabinet door with its opening vertically upward. This mismatch in spatial orientation makes it difficult for the sterilization light to effectively reach all surfaces of the tableware inside the box, resulting in noticeable sterilization dead zones.

[0004] In summary, existing pull-out basket disinfection structures suffer from inconvenience due to their unreasonable installation location and light emission direction design. They also occupy valuable space in the dish rack, hinder user operation, and fail to thoroughly disinfect small tableware items. Therefore, optimizing the spatial layout of the disinfection structure while ensuring effective disinfection—ensuring it doesn't interfere with dish handling and provides thorough and even disinfection of small tableware such as knives, forks, chopsticks, and spoons on the cabinet door side—is a crucial technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a sterilization structure for a pull-out basket, which aims to solve the technical problems in the prior art where the sterilizer body and its sterilization outlet are directly set in the inner cavity of the middle drawer, resulting in occupying the storage space for dishes and interfering with the operation of taking them out and putting them in, and the sterilization outlet being set horizontally so that it cannot effectively irradiate the knife and fork box on the side of the cabinet door, resulting in sterilization dead corners for small tableware.

[0006] The present invention discloses a disinfection structure for a pull-out basket, comprising a pull-out drawer located above the middle drawer of the pull-out basket, the pull-out drawer being independently arranged within the internal accommodating space of the middle drawer; the pull-out drawer having a base plate and side walls surrounding the periphery of the base plate, forming an accommodating space between the base plate and the side walls; the pull-out drawer being slidably installed inside a cabinet via track assemblies provided on its two side walls; a window extending along the depth direction of the pull-out drawer is provided on the base plate; a disinfection machine body is fixedly installed on the base plate corresponding to the window, the disinfection machine body being completely accommodated within the accommodating space; the disinfection outlet of the disinfection machine body is vertically aligned with the window so that disinfection light shines downward through the window; a guide plate is provided at the disinfection outlet, the guide plate being inclined towards both sides of the cabinet door to reflect the disinfection light into the cutlery box installed in the cutlery box mounting area.

[0007] As a preferred embodiment of the present invention, multiple guide plates are provided, all of which are longitudinally arranged at the disinfection outlet, and the multiple guide plates are spaced apart along the transverse direction of the disinfection outlet.

[0008] As a preferred embodiment of the present invention, the slots between adjacent guide plates on the left side of the disinfection outlet are inclined to the left, and the slots between adjacent guide plates on the right side of the disinfection outlet are inclined to the right, and the slots are formed by the walls of the two adjacent guide plates.

[0009] As a preferred embodiment of the present invention, the angle between the inclination direction of the slot and the horizontal plane is 30° to 60°.

[0010] In a preferred embodiment of the present invention, the top surface of the sterilizer body is equal to the top surface of the side wall.

[0011] As a preferred embodiment of the present invention, the accommodating spaces on the left and right sides of the sterilizer body are used to hold spare knives and forks, spare chopsticks or spare spoons.

[0012] As a preferred embodiment of the present invention, the top surface of the sterilizer body is provided with a groove, and a partition is provided in the groove. The partition divides the groove into two accommodating compartments, each of which is used to place spare knives and forks, spare chopsticks or spare spoons.

[0013] As a preferred embodiment of the present invention, the window is a rectangular opening extending along the depth of the drawer.

[0014] In a preferred embodiment of the present invention, the bottom surface of the pull-out drawer is higher than the top surface of the middle drawer.

[0015] As a preferred embodiment of the present invention, the track assembly includes a fixed track fixedly installed on the inner wall of the cabinet and a movable track fixedly installed on the side wall, wherein the movable track and the fixed track are slidably engaged.

[0016] The disinfection structure of the pull-out basket described in this invention, by independently placing the pull-out drawer above the middle drawer and installing the disinfection unit within the drawer's storage space, ensures that the disinfection unit does not occupy the internal storage space of the middle drawer. This avoids the disinfection unit and its outlet encroaching on the dish storage area and retrieval space, effectively improving the space utilization of the middle drawer and the user's convenience in retrieving dishes. Simultaneously, by installing guide plates at the disinfection outlet that are tilted towards both sides of the cabinet door, the downward-facing disinfection light is reflected by the guide plates and guided into the cutlery boxes on both sides of the cabinet door, ensuring sufficient illumination of the knives, forks, chopsticks, and spoons stored in the boxes. This effectively eliminates disinfection dead zones caused by the horizontal placement of the disinfection outlet in existing technologies, improving the comprehensiveness and uniformity of disinfection. Furthermore, the pull-out drawer is removably installed inside the cabinet via a track assembly, allowing users to easily maintain, clean, or replace the disinfection unit after pulling it out.

[0024] The technical solutions in the embodiments of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] In this invention, it should be noted that if the embodiments of the invention involve directional indicators (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0026] like Figure 1 - Figure 7 As shown, the present invention discloses a disinfection structure for a pull-out basket, comprising a pull-out drawer 1 located above the middle drawer of the pull-out basket, the pull-out drawer being independently arranged within the internal accommodating space of the middle drawer; the pull-out drawer having a base plate 2 and side walls 3 surrounding the periphery of the base plate, forming an accommodating space 4 between the base plate and the side walls; the pull-out drawer being detachably installed inside the cabinet via track assemblies 5 provided on its two side walls; a window 6 extending along the depth direction of the pull-out drawer is provided on the base plate; a disinfection machine body 7 is fixedly installed on the base plate at a position corresponding to the window, the disinfection machine body being completely accommodated within the accommodating space; the disinfection outlet 8 of the disinfection machine body is vertically aligned with the window so that disinfection light shines downward through the window; a guide plate 9 is provided at the disinfection outlet, the guide plate being inclined toward both sides of the cabinet door to reflect the disinfection light toward the interior of the cutlery box installed in the cutlery box mounting area.

[0027] By independently placing the pull-out drawer above the middle drawer and installing the sterilizer within its space, the sterilizer does not occupy the internal space of the middle drawer. This avoids the sterilizer and its outlet encroaching on the dish storage area and retrieval space, effectively improving the space utilization of the middle drawer and the convenience of dish retrieval for users. Simultaneously, by installing guide plates at the sterilization outlet that tilt towards both sides of the cabinet door, the downward-facing sterilization light is reflected and guided into the cutlery boxes on both sides of the cabinet door, ensuring thorough illumination of the knives, forks, chopsticks, and spoons stored there. This effectively eliminates sterilization dead zones caused by the horizontal placement of the sterilization outlet in existing technologies, improving the comprehensiveness and uniformity of sterilization.

[0028] Because the bottom surface of the pull-out drawer is higher than the top surface of the middle drawer, when the middle drawer is fully pushed into the cabinet and closed, a predetermined gap is maintained vertically between the top surface of the middle drawer and the bottom surface of the pull-out drawer. This gap ensures that the top surface of the middle drawer will not contact or collide with the bottom surface of the pull-out drawer during the sliding process. Simultaneously, the dishes stored in the middle drawer and the cutlery box installed inside the cabinet door do not protrude above the top surface of the middle drawer under normal storage conditions (dishes, when placed in a conventional manner, have their highest point below the top surface of the middle drawer, and the highest point of the cutlery box is also below the top surface of the middle drawer). This ensures that the sliding operation of the middle drawer is not interfered with by the drawer bottom. Furthermore, when the sterilizer inside the pull-out drawer is operating, its sterilization light can pass unobstructed through the window and shine onto the dishes and cutlery box.

[0029] The track assembly 5 includes a fixed rail 51 fixedly installed on the inner wall of the cabinet and a movable rail 52 fixedly installed on the side wall 3 of the pull-out drawer 1. The fixed rail 51 extends along the depth of the cabinet and is fixedly connected to the left and right inner walls of the cabinet by screws. The movable rail 52 extends along the depth of the pull-out drawer 1 and is fixedly connected to the outer surface of the left and right side walls 3 of the pull-out drawer 1 by screws. The movable rail 52 is slidably embedded in the fixed rail 51, and the movable rail 52 and the fixed rail 51 slide against each other, so that the pull-out drawer 1 can slide back and forth along the extension direction of the fixed rail 51 via the movable rail 52, thereby realizing the push-pull operation of the pull-out drawer 1 relative to the cabinet. When the user pulls the drawer 1 outward, the moving rail 52 slides along the fixed rail 51 toward the cabinet door, and the drawer 1 is pulled out of the cabinet so that the sterilizer body 7 can be maintained or cleaned; when the user pushes the drawer 1 inward, the moving rail 52 slides along the fixed rail 51 toward the cabinet, and the drawer 1 is pushed into the cabinet, returning to the storage state.

[0030] A window 6 extending along the depth of the drawer 1 is provided on the base plate 2. The window 6 is a rectangular opening penetrating the upper and lower surfaces of the base plate 2. The length of the window 6 is set along the depth of the drawer 1, and the width of the window 6 is set along the lateral direction of the drawer 1. The length of the window 6 in the depth direction is equal to the length of the disinfection outlet 8 of the disinfection machine body 7 in the depth direction, and the width of the window 6 in the lateral direction is equal to the width of the disinfection outlet 8 of the disinfection machine body 7 in the lateral direction. The disinfection machine body is fixed to the base plate by screws. The vertical projection of the disinfection outlet 8 of the disinfection machine body 7 falls completely within the opening area of ​​the window 6, thereby ensuring that the disinfection light generated by the disinfection machine body 7 during operation can pass through the window 6 without obstruction and shine downwards into the middle drawer.

[0031] Multiple guide plates 9 are provided, all located at the disinfection outlet 8. Each guide plate 9 is a long strip extending along the depth of the drawer 1 (i.e., longitudinally arranged), and the end of each guide plate 9 is integrally formed with the bottom plate of the disinfection machine body 7. The multiple guide plates 9 are arranged at equal intervals along the transverse direction of the disinfection outlet 8, forming a slot 10 between adjacent guide plates 9. This slot 10 is enclosed by the opposing walls of the two adjacent guide plates 9, forming part of the disinfection outlet, through which disinfection light passes through the window and shines into the middle drawer. The slots 10 between adjacent guide plates 9 on the left side of the disinfection outlet 8 are inclined to the left, that is, the extension direction of the slot 10 gradually shifts to the left from its upper inlet to its lower outlet; the slots 10 between adjacent guide plates 9 on the right side of the disinfection outlet 8 are inclined to the right, that is, the extension direction of the slot 10 gradually shifts to the right from its upper inlet to its lower outlet. The angle between the inclination direction of each slot 10 and the horizontal plane is 30° to 60°, preferably 45°. The disinfection light, reflected by the walls of each guide plate 9, passes through the inclination direction of each slot 10. The left slot 10 directs the disinfection light to the left, and the right slot 10 directs it to the right, ultimately entering the cutlery boxes on the left and right sides of the cabinet door to disinfect the cutlery, chopsticks, and spoons stored therein. Furthermore, the grid-like structure formed by the spaced-apart guide plates 9 provides protection for the disinfection outlet 8.

[0032] The top surface of the sterilizer body is equal to the top surface of the side wall. The sterilizer body 7 is fixedly installed on the base plate 2 with screws, and the sterilizer body 7 is completely contained within the receiving space 4. The top surface of the sterilizer body 7 is flush with the top surface of the side wall 3, that is, the upper surface of the sterilizer body 7 and the upper end surface of the side wall 3 are on the same horizontal plane. With this arrangement, the pull-out drawer 1 remains flat in its top surface direction (i.e., the plane formed by the top surface of the side wall 3 and the top surface of the sterilizer body 7), eliminating the protrusion structure caused by the sterilizer body 7 protruding from the top surface of the side wall 3. This helps to maintain the integrity of the pull-out drawer 1 and avoids the protrusion structure from hindering the normal pull-out operation of the pull-out drawer 1 or interfering with other internal structures of the cabinet.

[0033] The storage spaces on the left and right sides of the sterilizer body are used to hold spare cutlery, chopsticks, or spoons. The sterilizer body 7 is fixedly installed in the middle of the base plate 2 with screws. The left and right sides of the sterilizer body 7 form storage spaces not occupied by the sterilizer body 7 between it and the side walls 3 of the pull-out drawer 1. These storage spaces on the left and right sides are enclosed by the upper surface of the base plate 2 and the inner surface of the side walls, forming a shallow dish shape with an open top. Users can place spare cutlery, chopsticks, or spoons directly on the upper surface of the base plate 2 within the storage spaces on the left and right sides of the sterilizer body 7. Since these storage spaces on the left and right sides are located inside the pull-out drawer, and the sterilization light shines downwards when the sterilizer body is working, the spare cutlery, chopsticks, or spoons placed in these storage spaces are not in the path of the sterilization light and will not be sterilized. They are only for daily storage, making full use of the internal space of the pull-out drawer and improving the cabinet's storage capacity. In addition, the top surface of the bottom plate of the storage space on both sides is flat, which is conducive to the stable placement and use of spare knives, forks, chopsticks or spoons.

[0034] The top surface of the sterilizer body 7 has a groove 11, which is a groove-shaped space formed by the downward indentation of the top surface of the sterilizer body 7. A partition is fixedly installed inside the groove 11, extending along the depth of the pull-out drawer 1. The lower end of the partition is fixedly connected to the bottom wall of the groove 11, and the upper end of the partition is lower than or flush with the top surface of the sterilizer body 7. The partition divides the internal space of the groove 11 into two independent storage compartments, namely the left storage compartment located on the left side of the partition and the right storage compartment located on the right side of the partition. The upper end of each storage compartment is open, allowing users to place spare knives and forks, spare chopsticks, or spare spoons into the left and right storage compartments respectively. For example, spare chopsticks can be placed in the left storage compartment and spare spoons in the right storage compartment, thus achieving classified storage and convenient access for users. Since the groove 11 is located on the top surface of the sterilizer body 7, and spare knives, forks, chopsticks or spoons are all accommodated in the groove 11, it will not occupy the additional storage space 4 of the pull-out drawer 1, nor will it affect the normal operation of the sterilizer body 7.

[0035] The above embodiments are only used to illustrate the detailed solutions of the present invention. The present invention is not limited to the above detailed solutions, that is, it does not mean that the present invention must rely on the above detailed solutions to be implemented. Those skilled in the art should understand that any improvements to the present invention, equivalent substitutions of the raw materials of the inventive product, addition of auxiliary components, selection of specific methods, etc., all fall within the protection scope and disclosure scope of the present invention.
