[0025] like Figure 1 and Figure 2 As shown, this embodiment provides a base structure for a dishwasher, including a washing heating pump 1 with a water inlet and a water outlet, a water cup 3, a drain pump 4, a water diversion valve 5 and a pressure switch assembly 6 arranged on the base structure, the water cup 3 is arranged on the vertical center line of the base and close to the side of the dishwasher cabinet door, the drain pump 4 and the washing heating pump 1 are arranged on the side away from the dishwasher cabinet door, the axis of the drain pump 4 passes through the center point of the water cup 3, one side of the drain pump 4 is connected to the water cup 3, and the other side of the drain pump 4 extends toward the side away from the dishwasher cabinet door. The base structure for a dishwasher described in the present invention concentrates the weight on the side away from the dishwasher cabinet door, and the dishwasher is not easy to tip over when the door is opened, and is very stable; the chassis structure design is more compact, occupies less space, and the water flow is smoother.

[0026] Specifically, the angle between the axis of the drainage pump 4 and the horizontal axis of the water cup 3 is 0-90 degrees.

[0027] Specifically, the water cup 3 is provided with a water cup water inlet 301, a water cup water outlet 302 and a water cup water outlet 303. A filter is installed at the water cup water inlet 301, and the water cup water inlet 301 is arranged in a groove shape. In this embodiment, the shape of the water cup water inlet 301 is circular, but it is not limited to a shape of the water cup water inlet 301. The shape of the water cup water inlet 301 can be various shapes, such as oval, square, etc.

[0028] Specifically, the water inlet of the washing heating pump 1 is connected to the water outlet 302 of the water cup through the elbow 2. Integrating the washing pump and the heating component into the washing heating pump 1 reduces the number of installation components, facilitates installation, and reduces water leakage nodes.

[0029] More specifically, the elbow 2 is a right-angle elbow, and the elbow 2 includes a first pipe section 21 and a second pipe section 22 connected to each other, the first pipe section 21 and the second pipe section 22 are vertically arranged, the first pipe section 21 is connected to the water cup 3, and the second pipe section 22 is connected to the washing and heating pump 1. The axis of the first pipe section 21 and the horizontal axis of the water cup 3 are in a straight line, and the axis of the second pipe section 22 and the axis of the washing and heating pump 1 are in a straight line. The arrangement of the right-angle elbow makes the base structure of the dishwasher more compact.

[0030] Specifically, the drainage pump 4 is connected to the water cup drainage port 303 .

[0031] Specifically, the drain pump 4 and the washing heating pump 1 are located on the same side of the horizontal axis of the water cup 3 and on both sides of the vertical axis of the water cup 3. The arrangement of the drain pump 4 and the washing heating pump 1 is conducive to the uniform distribution of the dishwasher base structure, making the base structure more stable.

[0032] Specifically, the water diverter valve 5 is arranged on a side away from the dishwasher cabinet door, the water inlet of the water diverter valve 5 is connected to the water outlet of the washing heating pump 1 through a pipe, the outlet of the water diverter valve 5 is connected to the spray arm, and the water diverter valve 5 directs water into the spray arm.

One end of the pipe of the pressure switch assembly 6 is connected to the washing heat pump 1, and the other end is connected to the water diverter valve 5. When the pressure switch assembly 6 detects that the water pressure reaches the set value, it means that the water volume is sufficient at present, and the pressure switch assembly 6 controls the heating component of the washing heat pump 1 to work. When the pressure detected by the pressure switch assembly 6 does not reach the set value, it means that the water volume is insufficient at this time, and the pressure switch assembly 6 controls the heating component of the washing heat pump 1 to stop working. The setting of the pressure switch assembly 6 avoids the waste of heating element energy on the one hand, and avoids dangerous situations such as dry burning in the dishwasher on the other hand, so that the safety performance of the sink dishwasher is further improved and the user experience is good.

[0034] Specifically, it also includes a dishwasher cabinet door connector 7, which is arranged at the front end side of the base close to the dishwasher cabinet door to connect the base and the dishwasher cabinet door.

[0035] More specifically, the dishwasher cabinet door connecting member 7 is not specifically limited, and can be a positioning hinge support member, or a rotating shaft mounting member, etc.

[0036] Specifically, an electric control box mounting structure 8 and a softener mounting structure 9 are provided. The electric control box mounting structure 8 is provided at the front end of the side of the base close to the dishwasher cabinet door, and the softener mounting structure 9 is provided at the front end of the side of the base away from the dishwasher cabinet door. The electric control box mounting structure 8 and the softener mounting structure 9 are provided to install the electric control box 80 and the softener 90, and also make the base structure more compact.

[0037] More specifically, the electric control box mounting structure 8 is provided with a clamping column, and the electric control box 80 is provided with a clamping hole. The electric control box 80 is positioned and clamped with the electric control box mounting structure 8 through the clamping column and the clamping hole.

[0038] More specifically, the softener mounting structure 9 is used to mount a softener 90. A respirator 10 is mounted on the upper end of the softener 90 near the side wall of the dishwasher. A brine tank 11 is disposed at the lower end of the softener 90. A resin tank 12 is disposed next to the brine tank 11. The respirator 10 provides a limited flow of water for softening for washing dishes to the softener 90 of the dishwasher, and prevents the backflow of water inside the dishwasher, which greatly reduces the manufacturing cost and the maintenance cost of the dishwasher, and the operation is stable, safe and reliable. The softener 90 can effectively remove calcium ions in the water. When the water passes through the softener, the calcium ions in the water are absorbed by the salt in the brine tank 11 in the water softener, and then the salt releases sodium ions into the water, which is conducive to cleaning the dishes.

[0039] Specifically, the softener 90, the respirator 10, the brine tank 11 and the resin tank 12 are installed on the side away from the dishwasher cabinet door, which is conducive to concentrating the weight on the side away from the dishwasher cabinet door. When the door is opened, the dishwasher is not easy to tip over and is very stable.

[0040] Specifically, the elbow 2 and the tube are both flexible tubes. Further, the elbow 2 and the tube are both flexible tubes such as rubber tubes. Setting the elbow 2 and the tube as flexible tubes can shorten the water system of the dishwasher, reduce the pressure loss of the washing heat pump 1, make the water path smooth, improve the washing efficiency, reduce water pollution, reduce vibration, and reduce noise.

[0041] When the dishwasher is working, water enters the breather 10 through the hose, and then communicates with the resin tank 12 of the softener 90 and the brine tank 11 of the softener 90 through two water outlets. The water in the resin tank 12 is filtered and enters the dishwasher cabinet. The water in the cabinet is pumped out by the washing and heating pump 1, the temperature rises, and flows through the pressure switch assembly 6 through the outlet of the washing and heating pump 1, and then flows to the water diversion valve 5, and then flows to the spray arm, and then sprays to the inner cavity of the dishwasher. After washing, part of the water flow is collected in the water cup 3, and then flows to the washing and heating pump 1 through the elbow 2; the other part is discharged to the breather 10 through the drainage pump 4, and then enters the dishwasher cabinet through the softener 90. This cycle works to achieve a better washing effect.
