Abstract
Description
Technical Field
[0001] This utility model relates to dishwashers, and more specifically, to a self-priming pump mounting structure, and also to a dishwasher having the self-priming pump mounting structure. Background Technology
[0002] Currently, dishwashers typically require an external pressurized water source, such as a tap, to supply water for washing. This means that dishwashers have specific installation requirements; if a pre-installed water pipe doesn't exist, they cannot function properly. To improve flexibility, dishwashers are usually equipped with a self-priming pump connected to the water inlet, allowing them to draw water from external sources without pressurization.
[0003] In addition, in order to achieve zero residual water in the dishwasher's water cup, a self-priming pump is installed in the dishwasher's drain line. Generally, a positive displacement pump is used to drain the residual water and thus achieve zero residual water.
[0004] Therefore, some dishwashers typically have two self-priming pumps inside their casing, usually installed separately. Furthermore, self-priming pumps generate vibration and noise during operation, and current dishwashers lack optimal installation structures for them, often simply fixing them directly to the dishwasher's piping chamber with screws.
[0005] Therefore, a new solution is needed to address this problem. Utility Model Content
[0006] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a self-priming pump mounting structure and a dishwasher.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: a self-priming pump mounting structure, comprising a base, a loading seat, and two self-priming pumps, wherein the loading seat is fixedly connected to the base, and the loading seat comprises two loading chambers integrally connected, wherein the loading chambers are hollow inside, and the two self-priming pumps are respectively installed in the two loading chambers; the first end of the loading chamber is closed, the second end of the loading chamber is open, and at least a portion of the self-priming pump extends into the loading chamber from the second end of the corresponding loading chamber.
[0008] The present invention is further configured such that the loading seat is made of rubber material, and the self-priming pump is elastically pressed and fixed to the inner wall of the loading chamber.
[0009] The present invention is further configured such that each of the self-priming pumps is provided with two self-priming ports, which are used for liquid inlet and outlet respectively; the first end of the loading chamber has two through holes, and the two self-priming ports extend out from the two through holes respectively.
[0010] The present invention is further configured such that the loading base also includes a connecting block, and the two loading chambers are integrally connected by the connecting block, and the connecting block is fixedly connected to the base by screws.
[0011] The present invention is further configured such that the base is integrally fixedly connected to an installation block, one side of the connecting block abuts against the installation block, and a pressing block is provided on the side of the connecting block away from the installation block. The pressing block, the connecting block, and the installation block are connected and fixed together by screws.
[0012] The present invention is further configured such that the pressing block includes two limiting parts, which are respectively arranged toward the two loading chambers, and the limiting parts are located on the side of the loading chamber facing away from the base.
[0013] The present invention is further configured such that the base is integrally fixedly connected with two sets of snap-fit components, the two sets of snap-fit components are respectively located on both sides of the loading seat, and the two sets of snap-fit components are used to block and limit the two sides of the loading seat.
[0014] The present invention is further configured such that the snap-fit component is fixedly connected to a wedge-shaped snap-fit block, the loading compartment is fixedly connected to a snap-fit block, the snap-fit block has a snap-fit groove, and the wedge-shaped snap-fit block and the snap-fit groove are snap-fitted together.
[0015] The present invention is further configured such that the base is integrally fixedly connected with two sets of limiting blocks one and two sets of limiting blocks two, which correspond to two sets of self-priming pumps respectively. The limiting blocks one and two sets of limiting blocks are distributed along the direction of the first end and the second end, and are used to block and limit the two ends of the self-priming pump respectively.
[0016] This utility model also provides a dishwasher, including the self-priming pump mounting structure as described above. Of the two self-priming pumps, the first self-priming pump is used to self-prime water into the dishwasher, and the second self-priming pump is used to self-prime water out of the dishwasher.
[0017] In summary, this utility model has the following beneficial effects:
[0018] By using a loading seat, two self-priming pumps can be installed as a single unit. Then, screws and press-fit blocks can be used to fix the loading seat and the two self-priming pumps to the base at the bottom of the dishwasher. By setting multiple limiting structures on the outer periphery of the loading seat, the loading seat and the outer periphery of the two self-priming pumps can be blocked and limited to prevent the self-priming pumps from moving around due to vibration.
[0019] The loading seat is made of rubber, which has a certain degree of elasticity and vibration absorption. On the one hand, it can maintain the connection stability between the self-priming pump and the loading chamber. On the other hand, the rubber material also has a certain buffering effect, which can reduce the vibration and noise of the self-priming pump during operation.
[0020] Of the two self-priming pumps, the first self-priming pump is used to self-prime water into the dishwasher. It is connected to the water inlet pipe through two self-priming interfaces and can generate a self-priming effect in the water inlet pipe, drawing water from an external pressureless water source as washing water for the dishwasher. The second self-priming pump is used to self-prime drain water from the outside of the dishwasher. Through self-priming drainage, water in the water cup at the bottom of the inner tank can be discharged, eliminating residual water at the bottom of the water cup. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This embodiment discloses a self-priming pump mounting structure, suitable for dishwashers, see reference. Figures 1-3 As shown, it includes a base 1, a loading seat 2, and two self-priming pumps 4, which are installed at the bottom of the dishwasher using the mounting structure in this embodiment.
[0027] In this embodiment, the base 1 is the inner tank base of the dishwasher, and the loading seat 2 is fixedly connected to the base 1, specifically located on the lower side of the inner tank base. The two self-priming pumps 4 are fixedly installed inside the loading seat 2, enabling the two self-priming pumps 4 to be installed and fixed as a single unit.
[0028] The loading base 2 is made of rubber and includes two integrally connected loading chambers 21. The interior of each loading chamber 21 is hollow, and its internal shape is adapted to the shape of the self-priming pump 4. The two self-priming pumps 4 are respectively installed within the two loading chambers 21. The self-priming pumps 4 and the inner walls of the loading chambers 21 are elastically pressed and fixed together. The two self-priming pumps 4 can be integrally assembled through friction between them, or they can be bonded together with adhesive. The loading base 2, being made of rubber, has a certain degree of elasticity. On the one hand, it maintains the connection stability between the self-priming pumps 4 and the loading chambers 21; on the other hand, the rubber material also has a certain cushioning effect, reducing vibration and noise during operation of the self-priming pumps 4.
[0029] The first end 212 of the loading chamber 21 is closed, and the second end 213 of the loading chamber 21 is open. Correspondingly, the self-priming pump 4 also has a first end and a second end, which correspond to the first end 212 and the second end 213 of the loading chamber 21. The first end 212 of the self-priming pump 4 extends into the loading chamber 21 from the second end 213 of the corresponding loading chamber 21.
[0030] At the first end of the self-priming pump 4, two self-priming ports 41 are provided, which are used for liquid inlet and outlet respectively. At the first end 212 of the loading chamber 21, two through holes 2121 are provided, and the two self-priming ports 41 extend out from the two through holes 2121 respectively.
[0031] Reference Figure 2 As shown, the base 1 is integrally and fixedly connected with two sets of limiting blocks 13 and 14, which correspond to the two sets of self-priming pumps 4 respectively. The limiting blocks 13 and 14 are distributed along the direction of the first end 212 and the second end 213, respectively, and are used to block and limit the two ends of the self-priming pump 4. Specifically, the limiting block 13 is located outside the first end 212 of the loading chamber 21, and the limiting block 14 is located outside the second end of the self-priming pump 4. The limiting blocks 13 and 14 can respectively block and limit the two ends of the self-priming pump 4, preventing axial movement of the self-priming pump 4.
[0032] The loading base 2 also includes a connecting block 22, through which the two loading chambers 21 are integrally connected, with the two loading chambers 21 located on opposite sides of the connecting block 22. The connecting block 22 is fixedly connected to the base 1 by screws 5, thereby enabling the loading base 2 to be mounted on the base 1.
[0033] The base 1 is integrally fixedly connected to the mounting block 11. One side of the connecting block 22 abuts against the mounting block 11, and a pressing block 3 is provided on the side of the connecting block 22 away from the mounting block 11. The pressing block 3, the connecting block 22, and the mounting block 11 are connected and fixed by screws 5. The screws 5 pass through the pressing block 3 and the connecting block 22, and are threadedly connected and fixed to the mounting block 11 to achieve threaded tightening and fixing.
[0034] Specifically, the base 1 is integrally fixedly connected to two mounting blocks 11, and threaded mounting holes 111 are provided at the ends of the two mounting blocks 11; correspondingly, the connecting block 22 has two support points, which are respectively pressed and fixed to the two mounting blocks 11. The pressing block 3 is integrally connected to two pressing parts 31, which are respectively pressed and fixed to the two support points of the connecting block 22, thus forming two support points on the loading seat 2.
[0035] The pressing block 3 includes two limiting parts 32, which are respectively arranged in the direction of the two loading chambers 21. The cross-sectional shape of the two limiting parts 32 forms a V-shaped structure. The limiting parts 32 are located on the side of the loading chamber 21 facing away from the base 1, and the loading chamber 21 can be blocked and limited by the limiting parts 32.
[0036] The base 1 is also integrally and fixedly connected with two sets of snap-fit parts 12, which are located on both sides of the loading seat 2. The two sets of snap-fit parts 12 can block and limit the movement of the two sides of the loading seat 2, thereby maintaining the positional stability of the loading seat 2 and the two self-priming pumps 4.
[0037] In addition, a wedge-shaped locking block 121 is fixedly connected to the snap-fit component 12, and the wedge-shaped locking block 121 gradually narrows towards the side facing away from the base 1. A snap-fit block 23 is fixedly connected to the outside of the loading compartment 21. The snap-fit block 23 has a locking groove 231. The shape of the locking groove 231 is adapted to the locking groove 231. The wedge-shaped locking block 121 and the locking groove 231 are engaged with each other, thereby maintaining the connection stability between the snap-fit component 12 and both sides of the loading base 2.
[0038] This embodiment also discloses a dishwasher, including an inner tub, a water inlet pipe, and a drain pipe. The inner tub has an inner tub base, which is the base 1 in the above embodiment.
