[0035] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] Embodiment

[0037] As Figures 1 to 3 shown, a dispenser provided in this embodiment includes: a receiving groove a1; a holding portion a2 provided on the first groove wall a101 of the receiving groove a1. The receiving groove itself is used to place sodium chloride, and the holding portion is connected to the receiving groove. When it is necessary to drive the receiving groove to move, the user can directly act on the holding portion to achieve the movement or rotation operation.

[0038] The receiving groove a1 in this embodiment is a square groove body with an open end surface, and the groove wall of the square groove body far 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.

[0039] In this embodiment, the receiving groove and the holding portion can be integrally formed or can be separated. When the integral forming method is adopted, the injection molding method can be directly used for preparation.

[0040] As a preferred embodiment, the receiving groove a1 is detachably provided on the holding portion a2. The user places the reaction solute salt into the receiving groove a1, holds the holding portion a2 and installs the dispenser on the dishwasher, so as to provide reaction substances for the preparation of electrolytic salt disinfectant water inside the dishwasher, which is beneficial to the disinfection method using electrolytic saline in the dishwasher. Further, in the dispenser of this embodiment, the receiving groove a1 is detachably provided on the holding portion. When the types of dishwashers are different, especially when the volume of the inner tank of the dishwasher is different, the amount of disinfectant required is also different, and the corresponding size of the receiving groove is also different at this time. The detachably provided receiving groove is convenient for replacing receiving grooves of different volumes to meet the needs of different types of dishwashers on the one hand, and on the other hand, it is convenient for replacement and cleaning when the receiving groove is blocked or the like.

[0041] Specifically, there is no excessive limitation on the specific disassembly method between the accommodation groove and the holding part. It can adopt the interference fit method or the threaded connection method. In this embodiment, a clamping structure a4 is provided between the accommodation groove a1 and the holding part a2. The clamping structure a4 includes a dispenser buckle a401 and a dispenser slot a402 that cooperate with each other. Among them, the dispenser buckle can be provided on the first groove wall, and the dispenser slot can be provided on the holding part; or the dispenser slot can be provided on the first groove wall, and the dispenser buckle can be provided on the holding part. Or, mutually cooperating dispenser slot and dispenser buckle structures are provided on both the first groove wall and the holding part at the same time. The dispenser buckle and the dispenser slot are common buckle and slot structures and will not be elaborated here. Further, in this embodiment, as Figure 1 shown, the holding part a2 includes a holding base a201 and a protective edge a202 circumferentially arranged along the inner edge of the holding base a201, and the dispenser slot a402 is provided on the protective edge a202. As a deformation, a plurality of dispenser slots can be arranged at intervals along the protective edge, and the preferred arrangement is an equidistant arrangement. As a deformation, the dispenser buckle can also be processed on the protective edge, and the dispenser slot can be processed on the accommodation groove.

[0042] The method of fixing with a buckle and a slot is simple and convenient to install. However, the fixing method of the buckle and the slot mostly uses the elastic deformation of the injection molded part material to achieve clamping, and the stability of this kind of clamping fixation is poor. Therefore, in this embodiment, a guiding protrusion a102 is formed on the end surface of the first groove wall a101 facing the holding part a2, and the holding part a2 further includes a guiding groove a203 provided on the holding base a201 and cooperating with the guiding protrusion a102. The guiding protrusion is inserted into the guiding groove, and a small-gap transition fit can be adopted between the two. To reduce shaking and lower the installation difficulty. The cooperation between the guiding protrusion and the guiding groove further enhances the connection strength between the holding part and the accommodation groove, ensures the stability of the clamping between the two, and prevents the problem that the dispenser buckle and the dispenser slot mentioned above are prone to shaking after a long time.

[0043] Further, the holding part a2 further includes a holding edge a204 provided between the holding base a201 and the protective edge a202. A first sealing groove a205 is formed between the holding edge a204 and the holding base a201, and a first sealing member a3 is provided in the first sealing groove a205. By providing the first sealing groove a205, the first sealing member a3 can be pressed tightly on the salt port flange b101, so as to realize the seal between the dispenser and the water tank, and avoid the water in the inner tank from entering the water tank through the dispenser and causing pollution to the water tank. Specifically, the first sealing member a3 is configured as a sealing ring structure. At the same time, the first sealing member itself is made of a flexible material, such as rubber, so that it can deform after being compressed and further form a seal.

[0044] In this embodiment, asFigure 1 As shown, a handle a206 is provided on the end face of the holding base a201 away from the accommodation groove a1. There is no excessive limitation on the structure of the handle itself. It can be protruded in a "one" shape on the holding base, so as to facilitate the user to rotate the whole dispenser. As a variant, the handle itself can also be in shapes such as "cross", etc., and there is no excessive limitation in this embodiment.

[0045] In this embodiment, in order to achieve the full dissolution of sodium chloride in the accommodation groove, a number of flow holes a103 are provided at the bottom of the accommodation groove a1. The flow holes are arranged at the bottom of the groove, which can ensure that the solution generated in the accommodation groove can flow out completely, preventing the bottom liquid from remaining in the accommodation groove and causing the subsequent disinfectant solution concentration to not meet the standard.

[0046] There is no excessive limitation on the number, arrangement mode and shape of the flow holes themselves. In terms of the arrangement mode, other arrangement modes can be adopted, such as arranged in a ring shape, triangular shape, etc. As a preferred embodiment, a number of flow holes a103 are arranged in a side-by-side straight line at the bottom a1 of the accommodation groove near the second groove wall a106. At the same time, in terms of the shape, the flow holes themselves can adopt regular shapes, such as rectangles, ellipses, etc., or irregular shapes, as long as the leakage function can be achieved. As a preferred embodiment, the flow holes themselves adopt circles. At the same time, the aperture range of the circular holes is greater than or equal to 0.5 mm and less than or equal to 5 mm. Through the above size setting method, it is prevented that the salt particles directly pass through the flow holes and escape from the accommodation groove.

[0047] In order to accurately control the dosage of sodium chloride in the accommodation groove, a number of scales a104 are also provided on the accommodation groove a1 along its groove depth direction. The scales a104 can be processed on the groove wall by etching process or by injection molding to form a protrusion protruding from the surface of the groove wall. The scales a104 are used to mark the real-time capacity of the accommodation groove a1. For different tableware and different pollution situations, the amount of salt required to participate in the chemical reaction will also be different. The design of the scales facilitates the user to control the amount of salt added, and thus realizes the precise preparation of the disinfectant solution concentration.

[0048] Furthermore, in this embodiment, a number of feet a105 are provided on the back of the bottom of the accommodation groove a1. The holding part and the accommodation groove are mostly designed into a circular structure, and it is easy to roll when placed, resulting in the spilling of the salt inside. Therefore, the foot structure is designed to limit the side turning of the dispenser when placed.

[0049] For the convenience of installing the dispenser, the dispenser in this embodiment is fixed on the salt discharge port b10 by a clamping method. The specific clamping method is rotary clamping. As a variant, press-in clamping or screw locking or threaded connection or magnetic attraction and other methods can also be adopted.

[0050] The installation position of the dispenser will be explained below. In this embodiment, the dispenser is installed inside the inner tank of the dishwashing device, and the dishwashing and disinfection principle adopted by the dishwashing device is as follows: cathode: 2Cl--2e=Cl2; anode: 2H2O + 2e-=H2 + 2OH-; total reaction: 2Cl- + 2H2O=H2 + Cl2 + 2OH-. A disproportionation reaction will occur between chlorine and water: Cl 2 +H 2 O=HCl + HClO. The generated HClO has certain oxidizing properties itself, thereby achieving the killing effect on bacteria and viruses. In this embodiment, common table salt is used, which is non-toxic and has stable properties, is not prone to deterioration, and is convenient for storage and electrolytic disinfection operations. In order to form electrolyzed saline, a water tank b0 is installed on the outer wall of the inner tank, and electrolyzed disinfection water is prepared in the water tank b0.

[0051] To install the dispenser, the water tank body b9 has a first water tank side wall b904, and the first water tank side wall b904 is attached to the inner tank wall d51 of the inner tank d5. The salt inlet b10 is provided on the first water tank side wall b904. Specifically, a salt port flange b101 protrudes towards the inner tank wall d51 at the edge of the salt inlet b10. A flange hole d52 through which the salt port flange b101 passes is provided on the inner tank wall d51, and the holding part a2 is clamped on the salt port flange b101. When installing the dispenser, the accommodating groove part extends into the water tank through the hollow hole of the salt port flange, and the holding part a2 is clamped on the salt port flange b101 by means of rotary clamping.

[0052] To clamp the holding part on the salt port flange, in this embodiment, several rotary buckles a5 protrude from the inner peripheral surface of the salt port flange b101. In this embodiment, there are two of them. As a variant, the number of rotary buckles can be set according to needs. Corresponding rotary slots a207 for cooperating with the rotary buckles are formed on the holding part a2.

[0053] Specifically, the rotary slot a207 includes: a guiding slot opening a2071 for guiding the cooperation with the rotary buckle a5; a positioning slot a2072 for locking the rotary buckle a5; and a travel guiding slot a2073 connecting the guiding slot opening a2071 and the positioning slot a2072 to provide a rotation stroke.

[0054] In this embodiment, in order to improve the connection stability of the dispenser on the salt port flange, in the direction of the travel guide groove a2073 towards the positioning card slot a2072, the slot size gradually decreases. Specifically, the slot size can decrease linearly or non-linearly, as long as the decreasing action can be achieved. In this embodiment, in order to achieve the action of decreasing the slot size, the two side slot edges of the travel guide groove a2073 are configured as curved surface guiding structures. Through the above setting method, the dispenser is gradually clamped during rotation, thus avoiding shaking or detachment. In this embodiment, the extension dimension of the positioning card slot itself is also limited. When the rotary buckle a5 is clamped to the positioning card slot a2072, the flow hole a103 of the accommodating groove a1 faces the drain port in the water tank b0. Through the above setting method, the water flowing out of the water tank acts fully inside the accommodating groove, so that the sodium chloride in the accommodating groove can be dissolved quickly and fully.

[0055] As Figure 4 and Figure 5 shown, the water tank in this embodiment is installed on the inner tank. In order to ensure the installation stability of the water tank on the inner tank, this embodiment also provides a water tank installation structure, which includes a fixing seat a6. The fixing seat a6 is itself arranged on the salt port flange b101, and after the fixing seat a6 is fixed in place, one end face of the fixing seat a6 abuts against the inner tank wall d51. By setting the fixing seat a6, through its cooperation with the salt port flange b101, the stable connection between the water tank and the inner tank can be achieved, and thus the stability of the whole dishwasher can be improved.

[0056] The shape of the fixing seat a6 itself is not limited. It can be circular or rectangular. As a preferred embodiment, the fixing seat itself is circularly arranged, and its center is hollowed out. Threads are provided on the inner wall of the fixing seat a6. Correspondingly, threads are provided on the outer wall of the salt port flange. Through the connection between the threads, the connection action between the water tank and the inner tank is realized. After the fixing seat itself is tightened, the end of the fixing seat will abut against the side wall of the inner tank. As a variant, the fixing seat a6 can also be tensioned and arranged on the salt port flange b101. Specifically, along the direction close to the salt discharge port b10, the outer wall size of the salt port flange b101 gradually increases. When the fixing seat a6 is assembled, as the fixing seat goes deeper, the fixing seat is gradually tensioned on the salt port flange b101.

[0057] To ensure the sealing performance between the dispenser and the salt port flange and prevent the water in the water tank from leaking into the inner tank through the fitting clearance between the dispenser and the salt port flange, in this embodiment, a first seal a3 is provided between the holding part a2 and the salt discharge port b10. Further, in this embodiment, a second seal 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 port flange b101. The dispenser is provided with a first seal a3, and a part of the first seal a3 is clamped in the second seal groove a7. By providing the second seal groove a7, it can cooperate with the first seal on the dispenser, thereby preventing the 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 water tank.

[0058] Specifically, the second seal groove is annularly arranged, and the first seal is arranged in the second seal groove. The first seal is made of a flexible material such as rubber, and the radius of the first seal is smaller than the radius of the second seal groove, so as to stably hold the first seal in the second seal groove.

[0059] Further, a plurality of tooling grooves a601 are provided on the end face of the fixing seat a6 away from the inner tank wall d51. The plurality of tooling grooves are arranged at equal intervals from each other, and the tooling grooves are recessed. An operator can put his hand into the tooling groove to rotate the tooling groove, or use a corresponding wrench structure to rotate and fix the fixing seat.

[0060] As Figure 4 and Figure 5 As shown, in this embodiment, to further achieve the sealed fit between the water tank and the inner tank and prevent water from flowing out through the gap between the water tank and the inner tank, a sealing edge b102 protrudes from the side of the first water tank side wall b904 facing the inner tank wall d51, and a third seal groove d53 is correspondingly formed on the inner tank wall d51. The sealing edge b102 is clamped in the third seal groove d53. Through the above arrangement, the connection sealing performance between the water tank and the inner tank can be improved. It can prevent the water outside the water tank from entering the inner tank, or the water in the inner tank from flowing into the gap between the water tank and the inner tank and contaminating the outer wall of the dishwasher or the surrounding environment.

[0061] Specifically, the sealing edge can be continuously arranged or discontinuously arranged. As a preferred embodiment, the sealing edge is continuously arranged. At this time, the sealing edge can be circular or rectangular. As a preferred embodiment, the sealing edge is circularly arranged. Correspondingly, the third seal groove also adopts a circular sealing method.

[0062] In this embodiment, the sealing rib can be integrally formed on the side wall of the first water tank or can be separately provided on the side wall of the first water tank. As a preferred embodiment, the sealing rib b102 is configured as an annular convex structure and can be provided on the side wall of the first water tank by integral injection molding.

[0063] Furthermore, in order to enhance the sealing performance between the water tank and the inner tank, a second seal b103 is clamped at the abutting portion between the outer peripheral surface of the salt port flange b101 and the flange hole d52. Specifically, the second seal b103 is provided in the form of an annular rubber ring, and at this time, the second seal b103 is directly made of rubber material.

[0064] In this embodiment, the setting position of the second seal b103 is not limited. It can be arranged close to the fixing seat or can be arranged deviating from the fixing seat. As a preferred embodiment, the lower edge of the fixing seat a6 abuts on the second seal b103. Through the above setting method, it can be avoided that the water in the inner tank enters the area between the water tank and the inner tank through the gap between the fixing seat and the inner tank wall, resulting in water flowing out of the dishwasher. Furthermore, multiple second seals can be provided, and the multiple second seals are concentric with each other. Along the direction away from the salt port flange, the inner diameter of the second seal gradually increases, so as to form a multi-level sealing structure. Specifically, the second seal b103 is configured as a sealing ring structure.

[0065] A dishwasher includes the above-mentioned dispenser, inner tank and water tank structure. Disinfectant water is prepared by electrolyzing brine in the water tank and acts on the inner tank. The dispenser is installed in the inner tank, and salt is put into the water tank through the salt inlet on the water tank to facilitate the preparation of brine in the water tank.

[0066] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
