Description

Technical Field

[0001] This invention relates to the field of household appliance technology, specifically to a dispenser and a dishwasher. Background Technology

[0002] With the improvement of living standards, dishwashers have gradually entered ordinary households, enhancing our quality of life. Generally, the main core components of existing dishwashers typically include: inner tank assembly, water cup assembly, spray arm assembly, filter assembly, washing pump, drain pump, and piping. Currently, dishwashers on the market generally use high temperatures (usually around 70℃) for primary cleaning and dish sterilization. Some also incorporate UVC ultraviolet light sterilization, silver ion antibacterial agents in parts materials, high-temperature steam sterilization, and hot air drying. Summary of the Invention

[0003] Therefore, the present invention aims to provide a dishwasher with disinfection and cleaning functions, thereby providing a dispenser and a dishwasher.

[0004] To address the aforementioned problems, the present invention provides a dispensing device, comprising: a receiving groove; and a holding part disposed on a first groove wall of the receiving groove, wherein the receiving groove is detachably disposed on the holding part.

[0005] Furthermore, a snap-fit ​​structure is provided between the receiving groove and the holding part.

[0006] Furthermore, the snap-fit ​​structure includes a dispenser buckle and a dispenser slot that cooperate with each other;

[0007] The dispenser buckle and dispenser slot are respectively disposed on the first slot wall and / or the holding part, and the other is disposed on the holding part and / or the first slot wall.

[0008] Furthermore, the gripping part includes a gripping base and a protective edge arranged circumferentially along the inner edge of the gripping base, and the dispenser buckle and / or the dispenser slot are disposed on the protective edge.

[0009] Furthermore, a guide protrusion is formed on the end face of the first groove wall facing the gripping part, and the gripping part also includes a guide groove disposed on the gripping base and cooperating with the guide protrusion.

[0010] Furthermore, the gripping part also includes a gripping stop disposed between the gripping base and the guard edge, and a first sealing groove is formed between the gripping stop and the gripping base, and a first sealing element is disposed in the first sealing groove.

[0011] Furthermore, the first seal is configured as a sealing ring structure.

[0012] Furthermore, a handle is provided on the end face of the holding base away from the receiving groove.

[0013] Furthermore, a plurality of flow holes are provided at the bottom of the receiving groove.

[0014] Furthermore, several of the flow holes are arranged in a straight line side by side at the bottom of the receiving groove near the second groove wall.

[0015] Furthermore, the flow passage is constructed as a circular hole, and the diameter of the circular hole is greater than or equal to 0.5 mm and less than or equal to 5 mm.

[0016] Furthermore, the receiving groove is provided with several scales along its depth direction, which are used to indicate the real-time capacity of the receiving groove.

[0017] Furthermore, several support legs are provided on the back side of the bottom of the receiving groove.

[0018] The present invention also provides a dishwasher, including the dispenser described above.

[0019] The technical solution of this invention has the following advantages:

[0020] 1. The dispensing device of this invention includes: a receiving tank; and a handle disposed on the first wall of the receiving tank. The user places the reactive solute salt into the receiving tank and holds the handle to install the dispensing device onto the dishwasher, thus providing the reactive substance for the preparation of electrolyzed salt disinfectant solution inside the dishwasher, thereby facilitating the use of electrolyzed salt water for disinfection inside the dishwasher. Furthermore, the receiving tank in the dispensing device of this invention is detachably disposed on the handle. When different types of dishwashers, especially different volumes of the dishwasher's inner drum, require different amounts of disinfectant solution, and the corresponding size of the receiving tank also varies. The detachable receiving tank facilitates the replacement of receiving tanks of different volumes to meet the needs of different types of dishwashers, and also facilitates replacement and cleaning when the receiving tank becomes clogged.

[0021] 2. In the dispenser of the present invention, a guide protrusion is formed on the end face of the first groove wall facing the holding part. The holding part also includes a guide groove disposed on the holding base and cooperating with the guide protrusion. The cooperation between the guide protrusion and the guide groove further enhances the connection strength between the holding part and the receiving groove, ensuring the stability of the engagement between the two and preventing the aforementioned dispenser buckle and dispenser slot from shaking over time.

[0022] 3. The dispensing device of the present invention further includes a holding stop disposed between the holding base and the guard edge, and a first sealing groove is formed between the holding stop and the holding base, and a first sealing element is disposed in the first sealing groove. The first sealing element is fitted into the first sealing groove in an interference fit manner to prevent leakage from the installation position of the dispensing device and the inner tub when the dispensing device is installed on the inner tub of the dishwasher.

[0023] 4. The dispensing device of the present invention has several flow holes at the bottom of the container tank. The flow holes are located at the bottom of the tank to ensure that the solution generated in the container tank can flow out completely, preventing the bottom liquid from remaining in the container tank and causing the subsequent disinfectant concentration to be substandard.

[0024] 5. In the dispenser of this invention, several flow holes are arranged in a straight line side-by-side at the bottom of the receiving tank near the second tank wall. Since the dispenser needs to be rotated at a certain angle during installation, the second tank wall is rotated downwards to a lower position, aligning the flow holes closer to the second tank wall. This arrangement, through flow guidance, better utilizes the outflow of the solution within the receiving tank. The side-by-side straight-line arrangement prevents dead zones and water accumulation at corners.

[0025] 6. In the dispenser of the present invention, the flow hole is constructed as a circular hole with a diameter range of greater than or equal to 0.5 mm and less than or equal to 5 mm. By constraining the size of the circular hole within the aforementioned range, it is ensured that the salt particles placed in the dispenser will not fall out through the flow hole when the user holds the dispenser.

[0026] 7. In the dispensing device of the present invention, several scales are also provided on the container along the depth direction of the container. The scales are used to mark the real-time capacity of the container so that users can confirm the amount of salt added, thereby realizing the precise preparation of disinfectant concentration.

[0027] 8. In the dispensing device of the present invention, several feet are provided on the back of the bottom of the receiving tank. Since the holding part and the receiving tank of the present invention are mostly designed as circular structures, they are prone to rolling when placed, which may cause the salt inside to spill out. Therefore, the foot structure is designed to prevent the dispensing device from tipping over when placed. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0048] Example

[0049] like Figures 1 to 3 As shown, the dispensing device provided in this embodiment includes: a receiving tank a1; and a holding part a2, which is disposed on the first tank wall a101 of the receiving tank a1. The receiving tank itself is used to hold sodium chloride, and the holding part is connected to the receiving tank. When it is necessary to move the receiving tank, the user can directly act on the holding part to realize the movement or rotation operation.

[0050] In this embodiment, the receiving groove a1 is a square groove with an opening at one end. The groove wall at the end of the square groove away from the dispensing end is defined as the first groove wall a101. As a variation, the shape of the receiving groove a1 can also be a circular groove, a polygonal groove, etc.

[0051] In this embodiment, the receiving groove and the holding part can be integrally formed or they can be manufactured separately. When integrally formed, they can be directly manufactured by injection molding.

[0052] In a preferred embodiment, the container a1 is detachably mounted on the handle a2. The user places the reactive solute salt into the container a1 and holds the handle a2 to attach the dispenser to the dishwasher, thus providing the reactant for the preparation of the electrolyzed salt disinfectant solution inside the dishwasher, facilitating disinfection using electrolyzed salt water. Furthermore, in this embodiment, the container a1 is detachably mounted on the handle. Different types of dishwashers, especially those with different inner drum volumes, require different amounts of disinfectant, and therefore require different container sizes. The detachable container facilitates replacement with containers of different volumes to meet the needs of different types of dishwashers, and also allows for easy replacement and cleaning when blockages occur.

[0053] Specifically, the method of disassembling the receiving groove and the holding part is not limited; it can be an interference fit or a threaded connection. In this embodiment, a snap-fit ​​structure a4 is provided between the receiving groove a1 and the holding part a2. The snap-fit ​​structure a4 includes a dispensing device buckle a401 and a dispensing device slot a402 that cooperate with each other; wherein, the dispensing device buckle can be provided on the first groove wall and the dispensing device slot can be provided on the holding part; or the dispensing device slot can be provided on the first groove wall and the dispensing device buckle can be provided on the holding part. Alternatively, both the first groove wall and the holding part can be provided with cooperating dispensing device slots and dispensing device buckle structures. The dispensing device buckle and the dispensing device slot are common buckle and slot structures, which will not be described in detail here. Further, in this embodiment, as Figure 1 As shown, the gripping part a2 includes a gripping base a201 and a protective edge a202 arranged circumferentially along the inner edge of the gripping base a201. A dispenser slot a402 is disposed on the protective edge a202. Alternatively, multiple dispenser slots can be arranged at intervals along the protective edge; a preferred arrangement is equal intervals. Another variation is that the dispenser clip is machined onto the protective edge, and the dispenser slots are machined onto the receiving groove.

[0054] While the snap-fit ​​and slot fixing method is simple and easy to install, it often relies on the elastic deformation of the injection-molded material, resulting in poor stability. Therefore, in this embodiment, a guide protrusion a102 is formed on the end face of the first groove wall a101 facing the holding part a2. The holding part a2 also includes a guide groove a203 disposed on the holding base a201 and cooperating with the guide protrusion a102. The guide protrusion is inserted into the guide groove, with a small gap transition fit between them to reduce shaking and lower installation difficulty. The fit between the guide protrusion and the guide groove further enhances the connection strength between the holding part and the receiving groove, ensuring the stability of the snap-fit ​​and preventing the aforementioned problem of shaking that can easily occur over time with the dispenser snap-fit ​​and dispenser slot.

[0055] Furthermore, the gripping part a2 also includes a gripping stop a204 disposed between the gripping base a201 and the guard edge a202. A first sealing groove a205 is formed between the gripping stop a204 and the gripping base a201, and a first sealing element a3 is disposed within the first sealing groove a205. By providing the first sealing groove a205, the first sealing element a3 can be pressed tightly onto the salt outlet flange b101, thereby achieving a seal between the dispenser and the water tank, preventing water in the inner tank from entering the water tank through the dispenser and contaminating the water tank. Specifically, the first sealing element a3 is constructed as a sealing ring structure. Simultaneously, the first sealing element itself is made of a flexible material, such as rubber, so that it can deform upon compression and further form a seal.

[0056] In this embodiment, as Figure 1 As shown, a handle a206 is provided on the end face of the holding base a201 away from the receiving groove a1. The structure of the handle itself is not strictly limited; it can be a straight protrusion on the holding base, facilitating the user's rotation of the dispenser. As a variation, the handle can also be a cross shape, etc., but this embodiment does not impose many limitations.

[0057] In this embodiment, to ensure the complete dissolution of sodium chloride in the container tank, several flow holes a103 are provided at the bottom of the container tank a1. The flow holes are located at the bottom of the tank to ensure that the solution generated in the container tank can flow out completely, preventing the presence of residual liquid in the container tank, which would cause the subsequent disinfectant concentration to be substandard.

[0058] The number, arrangement, and shape of the flow holes are not strictly limited. Regarding the arrangement, other methods can be used, such as a ring or triangular arrangement. In a preferred embodiment, several flow holes a103 are arranged in a straight line side-by-side at the bottom a1 of the receiving tank near the second tank wall a106. As for the shape, the flow holes can be regular, such as rectangular or elliptical, or irregular, as long as they allow for drainage. In a preferred embodiment, the flow holes are circular. Furthermore, the diameter of the circular holes is greater than or equal to 0.5 mm and less than or equal to 5 mm. This dimensional arrangement prevents salt particles from directly passing through the flow holes and escaping from the receiving tank.

[0059] To achieve precise control over the amount of sodium chloride used in the container, several scales a104 are installed along the depth of the container a1. These scales a104 can be machined onto the container wall using etching or injection molding to form protrusions on the surface of the container wall. The scales a104 indicate the real-time capacity of the container a1. The amount of salt required for the chemical reaction will vary depending on the type of tableware and the level of contamination. The scale design facilitates user control over the amount of salt added, thereby enabling precise preparation of the disinfectant solution concentration.

[0060] Furthermore, in this embodiment, several support feet a105 are provided on the back side of the bottom of the receiving tank a1. The handle and the receiving tank are mostly designed as circular structures, which are prone to rolling when placed, causing the salt inside to spill out. Therefore, a support foot structure is designed to prevent the dispenser from tipping over when placed.

[0061] For ease of installation, the dispenser in this embodiment is fixed to the salt dispensing port b10 using a snap-fit ​​method. Specifically, the snap-fit ​​method is rotational snap-fit. As variations, other methods such as press-fit, screw fastening, threaded connection, or magnetic attraction can also be used.

[0062] The installation location of the dispensing device is explained below. In this embodiment, the dispensing device is installed inside the inner tank of the dishwasher. The dishwasher uses the following disinfection principle: Cathode: 2Cl⁻ - 2e⁻ = Cl₂; Anode: 2H₂O + 2e⁻ = H₂ + 2OH⁻; Overall reaction: 2Cl⁻ + 2H₂O = H₂ + Cl₂ + 2OH⁻. A disproportionation reaction occurs between chlorine and water: Cl₂ + H₂O = HCl + HClO. The resulting HClO has oxidizing properties, thus killing bacteria and viruses. In this embodiment, commonly used table salt is used. It is non-toxic, stable, and does not easily deteriorate, making it convenient for storage and electrolytic disinfection. To form electrolyzed brine, a water tank b0 is installed on the outer wall of the inner tank. The water tank b0 is used to prepare the electrolyzed disinfectant water.

[0063] To facilitate the installation of the dispenser, the water tank body b9 has a first water tank side wall b904, which is fitted onto the inner tank wall d51 of the inner liner d5. A salt dispensing port b10 is located on the first water tank side wall b904. Specifically, the edge of the salt dispensing port b10 protrudes towards the inner tank wall d51, forming a salt port flange b101. The inner tank wall d51 has a flange hole d52 through which the salt port flange b101 passes. The holding part a2 is snapped onto the salt port flange b101. During installation, the receiving groove portion extends into the water tank through the hollow hole of the salt port flange, and the holding part a2 is snapped onto the salt port flange b101 using a rotating snap-fit ​​method.

[0064] To allow the gripping part to be snapped onto the salt outlet flange, in this embodiment, several rotating buckles a5 are protruding from the inner circumferential surface of the salt outlet flange b101. In this embodiment, there are two such buckles, but the number of rotating buckles can be set as needed. The gripping part a2 is correspondingly formed with rotating grooves a207 that mate with the rotating buckles.

[0065] Specifically, the rotating slot a207 includes: a guide slot a2071 that engages with the rotating buckle a5; a positioning slot a2072 that locks the rotating buckle a5; and a travel guide slot a2073 that connects the guide slot a2071 and the positioning slot a2072 to provide a rotational travel.

[0066] In this embodiment, to improve the connection stability of the dispenser on the salt outlet flange, the opening size of the travel guide groove a2073 gradually decreases in the direction from the positioning slot a2072. Specifically, the opening size can decrease linearly or non-linearly, as long as the reduction action is achieved. In this embodiment, to achieve the reduction action of the opening size, the two sides of the travel guide groove a2073 are constructed as curved guide structures. Through the above-mentioned arrangement, the dispenser is gradually clamped during rotation, thereby preventing shaking or dislodgement. In this embodiment, the extension dimension of the positioning slot itself is also limited. When the rotating buckle a5 is engaged with the positioning slot a2072, the flow hole a103 of the receiving slot a1 is positioned facing the drain outlet in the water tank b0. Through the above-mentioned arrangement, the water flowing out of the water tank fully acts inside the receiving slot, thereby achieving rapid and complete dissolution of sodium chloride in the receiving slot.

[0067] like Figure 4 and Figure 5 As shown, in this embodiment, the water tank is installed on the inner liner. To ensure the stability of the water tank installation on the inner liner, this embodiment also provides a water tank installation structure, which includes a fixing seat a6. The fixing seat a6 is itself disposed on the salt outlet flange b101, and after the fixing seat a6 is fixed in place, one end face of the fixing seat a6 abuts against the inner liner wall d51. By setting the fixing seat a6, a stable connection between the water tank and the inner liner can be achieved through its cooperation with the salt outlet flange b101, thereby improving the overall stability of the dishwasher.

[0068] The shape of the fixing seat a6 is not limited; it can be circular or rectangular. In a preferred embodiment, the fixing seat is circular with a hollowed-out center. Threads are provided on the inner wall of the fixing seat a6, and correspondingly, threads are provided on the outer wall of the salt inlet flange. The connection between the water tank and the inner liner is achieved through the threaded connection. After the fixing seat is tightened, its end will rest against the side wall of the inner liner. As a variation, the fixing seat a6 can be tensioned and mounted on the salt inlet flange b101. Specifically, the outer wall dimension of the salt inlet flange b101 gradually increases along the direction close to the salt inlet b10. When the fixing seat a6 is assembled, as it is inserted deeper, it gradually tightens and mounts on the salt inlet flange b101.

[0069] To ensure a tight seal between the dispenser and the salt inlet flange, and to prevent water from leaking into the inner tank through the gap between the dispenser and the salt inlet flange, a first sealing element a3 is provided between the handle a2 and the salt inlet b10 in this embodiment. Furthermore, in this embodiment, a second sealing groove a7 is formed between the end of the fixing seat a6 away from the inner tank wall d51 and the upper edge of the salt inlet flange b101. The dispenser is provided with the first sealing element a3, and a portion of the first sealing element a3 is fitted into the second sealing groove a7. By providing the second sealing groove a7, it can cooperate with the first sealing element on the dispenser, thereby preventing water in the inner tank from entering the water tank through the gap between the dispenser and the fixing seat and contaminating the water in the tank.

[0070] Specifically, the second sealing groove is annular, and the first sealing element is disposed in the second sealing groove. The first sealing element is made of a flexible material, such as rubber, and its radius is smaller than that of the second sealing groove, thereby stabilizing the first sealing element in the second sealing groove.

[0071] Furthermore, several tooling slots a601 are provided on the end face of the fixed seat a6 away from the inner wall d51. The multiple tooling slots are set at equal intervals, and the tooling slots themselves are recessed. The operator can put his hand into the tooling slot to rotate the tooling slot, or use a corresponding wrench structure to rotate and fix the fixed seat.

[0072] like Figure 4 and Figure 5As shown in this embodiment, to further achieve a sealed fit between the water tank and the inner tank and prevent water from flowing out through the gap between them, a sealing flange b102 is provided protruding from the side of the first water tank sidewall b904 facing the inner tank wall d51. A corresponding third sealing groove d53 is formed on the inner tank wall d51, and the sealing flange b102 is engaged with the third sealing groove d53. This arrangement improves the sealing performance between the water tank and the inner tank, preventing water from outside the water tank from entering the inner tank or water from inside the inner tank from flowing into the gap between them and causing contamination to the dishwasher's outer wall or the surrounding environment.

[0073] Specifically, the sealing edge can be continuous or discontinuous. In a preferred embodiment, the sealing edge is continuous, and in this case, it can be circular or rectangular. In a preferred embodiment, the sealing edge is circular. Correspondingly, the third sealing groove also uses a circular sealing method.

[0074] In this embodiment, the sealing edge can be integrally formed on the side wall of the first water tank or can be set separately on the side wall of the first water tank. As a preferred embodiment, the sealing edge b102 is constructed as an annular protrusion structure, and it can be integrally injection molded on the side wall of the first water tank.

[0075] Furthermore, to enhance the sealing performance between the water tank and the inner liner, a second sealing element b103 is clamped at the contact point between the outer circumference of the salt outlet flange b101 and the flange hole d52. Specifically, the second sealing element b103 is set in the form of an annular rubber ring, and in this case, the second sealing element b103 will be made directly of rubber material.

[0076] In this embodiment, the location of the second sealing element b103 is not limited. It can be located close to the fixing seat or offset from the fixing seat. As a preferred embodiment, the lower edge of the fixing seat a6 abuts against the second sealing element b103. With the above-described arrangement, water in the inner tank can be prevented from entering the area between the water tank and the inner tank through the gap between the fixing seat and the inner tank wall, thus preventing water from flowing out of the dishwasher. Furthermore, multiple second sealing elements can be provided, and the multiple second sealing elements are concentrically arranged with each other. Along the direction away from the salt port flange, the inner diameter of the second sealing element gradually increases, thereby forming a multi-layer sealing structure. Specifically, the second sealing element b103 is constructed as a sealing ring structure.

[0077] A dishwasher includes the aforementioned dispenser, inner tank, and water tank structure. Disinfectant water, prepared by electrolyzing brine in the water tank, is then applied to the inner tank. The dispenser is installed inside the inner tank and dispenses salt into the water tank through a salt inlet, facilitating the preparation of the brine in the tank.

[0078] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
