Description

Dish washer with water softener

Technical Field

The application belongs to the technical field of dish washing machines, and particularly relates to a dish washing machine with a water softener.

Background

In dishwashers available on the market today, water softeners are generally provided, which serve to soften the incoming mains water and reduce the water hardness. In daily-life water, insoluble precipitates (such as scale) are easily formed. For dishwasher applications, if the hardness of the water is high, on the one hand, scale may build up on the surface of the heating device in the dishwasher, severely impeding heat conduction, and also causing perforating corrosion, resulting in damage to the heating element; on the other hand, the surface of the dishwasher and washed tableware are not clean, and the washing quality of the dishwasher is affected. The water softener in the dish washer generally comprises a resin cavity and a salt cavity, and the working principle of the water softener is that the genes in ion exchange resin are used for replacing and removing the hardness components in the water body, such as Ca2+, Mg2+ and the like, so as to achieve the purpose of softening hard water, reduce the scale and the harm caused by the scale generated in the dish washer and effectively prolong the service life of the dish washer. In the above process, when the exchange ions on the resin are all changed into calcium and magnesium, the conversion effect of the resin is saturated, the conversion capability will be ineffective, and at this time, the calcium and magnesium ions need to be regenerated and replaced by sodium ions. In the regeneration process, the brine flows through the resin cavity and reacts with the resin in the resin cavity to replace calcium and magnesium ions with sodium ions, so that the soft water capacity of the resin is recovered. Wherein the resin is a yellow particulate matter, and can change into yellow after being soaked in water for a long time.

Conventional dishwashers typically locate the water softener at the bottom of the dishwasher. In practical application, water inside the water softener arranged at the bottom of the dish washer cannot be completely discharged to form residual water, and the residual water is soaked with resin for a long time and then becomes yellow water, and even flows to a water cup of the dish washer which is connected with the water softener. In the transportation process, if the machine rolls or jolts, the yellow water can remain on the appearance surface of the machine, and the use of the machine by a user is seriously influenced.

Therefore, there are still many defects in the water softener in the dishwasher, which is a technical problem that manufacturers of the dishwasher need to improve at present.

A description will now be given of a dishwasher having a water softener provided in an embodiment of the present application. Referring to fig. 1, 2 and 3, the dishwasher includes an inner container 100, a base 200, a water path assembly 300 and a water softener 400, wherein the inner container 100 and the base 200 are vertically disposed, and a water cup 201 communicated with the bottom of the inner container 100 is disposed in the base 200. The water softener 400 is connected to the water path assembly 300, and the water softener 400 and the water path assembly 300 are disposed on the same side of the liner 100. As shown in fig. 1, the water softener 400 and the waterway assembly 300 are hung on the same side wall of the liner 100; in this embodiment, the waterway assembly 300 is integrated with the anti-siphon component; in other embodiments, the waterway assembly 300 may be integrated with the breathing component, and is not limited herein. As shown in FIGS. 2 and 3, the water softener 400 has a resin chamber 1 and a salt chamber 2 therein, the water softener 400 has a bottom portion provided with a water outlet 11 communicating with the bottom portion of the resin chamber 1, the water outlet 11 is connected to the input end 202 of the water cup 201 through a pipe, and the water outlet 11 is located at a height higher than the bottom M of the water cup 201. The "bottom M of the cup 201" is understood to be the bottom surface of the cup 201 that can contain water.

Compared with the prior art, the dishwasher provided by the embodiment of the application has the advantages that the water softener 400 in the dishwasher is improved from the traditional water softener base 200 arranged in the dishwasher to the side part of the inner container 100 arranged in the dishwasher, and the water softener 400 is hung on the side wall of the inner container 100 and is connected with the water path assembly 300 of the dishwasher. The water outlet end 11 of the water softener 400 is arranged at the bottom of the water softener 400 and penetrates through the resin cavity 1 in the water softener 400 from the bottom. The water outlet end 11 is higher than the water containing bottom of the water cup 201 and is connected with the input end 202 of the water cup 201 through a pipeline. Therefore, the water outputted from the water channel assembly 300 is softened by the water softener 400 and then is delivered into the water cup 201, thereby forming the washing cycle water in the dishwasher.

Because the inner container 100 and the base 200 are arranged up and down, the water softener 400 is arranged on the side wall of the inner container 100, so that the water softener 400 and the water cup 201 in the base 200 have a height difference; moreover, the water outlet end 11 of the water softener 400 is higher than the water containing bottom of the water cup 201. Therefore, after the washing of the dishwasher is completed, the water liquid in the water softener 400 flows downwards under the action of gravity, and particularly the water liquid in the resin cavity 1 is discharged downwards into the water cup 201 through the water outlet end 11, so that the water liquid in the resin cavity 1 is completely discharged, the problem that the residual water is easily accumulated in the resin cavity 1 of the water softener 400 is effectively solved, the accumulated residual water and the resin in the resin cavity 1 are prevented from soaking to become yellow water, the water sanitation of the dishwasher is further ensured, and the dishwasher can be normally used.

In practical application, because the salt cavity 2 is loaded with the salt solution mixed with the salt, when the soft water capacity of the resin cavity 1 is reduced, the salt solution needs to be added into the resin cavity 1, so that a water passing channel is inevitably formed between the salt cavity 2 and the resin cavity 1, and in the position transfer process or the transportation process of the dishwasher, the water liquid in the salt cavity 2 is easy to overflow into the resin cavity 1, so that the water is accumulated in the resin cavity 1. Therefore, referring to fig. 4 and fig. 5 (the arrow direction in the figures is the water flow direction), the resin cavity 1 and the salt cavity 2 are adjacently arranged at the left and right sides inside the water softener 400, the top of the resin cavity 1 is provided with a water inlet 12, and the bottom side wall of the salt cavity 2 is provided with a water outlet 21, so that the water inlet 12 is arranged higher than the water outlet 21. A connecting channel 401 vertically arranged is arranged between the salt cavity 2 and the resin cavity 1, the upper end of the connecting channel 401 is communicated with the water inlet 12, and the lower end of the connecting channel 401 is communicated with the water outlet 21, so that a height difference is formed. Therefore, the trend of water flow is limited from the arrangement of the water path, the water liquid in the salt cavity 2 is prevented from easily permeating into the resin cavity 1 to form accumulated water, and the residual water in the resin cavity 1 is effectively discharged.

Referring to fig. 6, fig. 7 and fig. 8 (the arrow direction in the figures is the water flow direction), a check valve 3 is disposed in the connecting channel 401, the check valve 3 includes a valve element 31 and a valve seat 32, the bottom of the valve seat 32 has a valve port 320, the valve element 31 is disposed in the valve seat 32 and blocks the valve port 320 or is pushed by water flow to open the valve port 320. A limiting protrusion 33 for limiting the upward movement range of the valve core 31 is further provided in the connecting passage 401, and the limiting protrusion 33 is provided above the valve seat 32. In practical application, as shown in fig. 6 and 8, only in the operating state that the dishwasher is in operation and salt needs to be added to the resin chamber 1, sufficient water pressure is formed to push the valve core 31 of the check valve 3 away, so that the salt solution is added to the resin chamber 1. When the dishwasher stops operating, the salt adding function is closed, the valve core 31 is reset, the one-way valve 3 can stop water from flowing to the resin cavity 1, and the condition that water is accumulated in the resin cavity 1 is further eliminated.

Preferably, the internal water path structure of the water softener 400 is optimized, please refer to fig. 4, fig. 5 and fig. 7 (the arrow direction in the figures is the water flow direction), the water softener 400 is further provided with a water inlet 4, a first water flow channel 402, a second water flow channel 403 and a control valve 404 for opening and closing the first water flow channel 402 or the second water flow channel 403, the control valve 404 is disposed near the water inlet and performs switching control on the water path entering the first water flow channel 402 or the second water flow channel 403 from the water inlet. As shown in FIG. 5, the control valve 404 opens only the second water flow channel 403, so that the inlet water directly enters the resin chamber 1 along with the second water flow channel 403, and the resin in the resin chamber 1 is softened and then discharged from the water outlet 11 for washing. When salt needs to be added to the resin cavity 1, as shown in fig. 7, the control valve 404 only opens the first water flow channel 402, so that the inlet water firstly enters the salt cavity 2 along with the first water flow channel 402, the salt solution loaded in the salt cavity 2 is discharged to the connecting channel 401 from the water outlet 21 on the bottom side wall of the salt cavity 2, the check valve 3 in the connecting channel 401 is opened by the water pressure of the inlet water, then the inlet water enters the resin cavity 1 from the water inlet 12 at the top of the resin cavity 1, the salt solution is further added into the resin cavity 1, and after the resin in the resin cavity 1 recovers the soft water capacity, the softened water liquid is output from the water outlet end 11 at the bottom of the resin cavity 1 for washing application.

Referring to fig. 4, 5 and 7 (the direction of the arrow in the figures is the water flow direction), the first water flow channel 402 is connected from the water inlet 4 to the top of the salt cavity 2, the second water flow channel 403 is connected from the water inlet 4 to the water inlet 12 of the resin cavity 1, and the first water flow channel 402 and the second water flow channel 403 are arranged side by side and surround from the side of the resin cavity 1 to the top of the resin cavity 1. On one hand, the waterway structure can avoid influencing the structure of a connecting channel 401 between the resin cavity 1 and the salt cavity 2 to form an avoiding arrangement; on the other hand, the water channel structure forms a height difference, and forms a water pressure limit for the water flow entering the water softener 400, when the water pressure is sufficient, such as the dishwasher is in operation, the water flow can enter the corresponding chamber through the first water flow channel 402 or the second water flow channel, so as to prevent the water flow from naturally flowing into the resin chamber 1 in a natural flowing state, i.e. the dishwasher is not in operation, and effectively prevent the resin chamber 1 from storing residual water.

In the present embodiment, referring to fig. 4, the first water flow channel 402, the second water flow channel 403, the connecting channel 401, the resin chamber 1 and the salt chamber 2 are formed by separating ribs inside the water softener 400. Wherein, the water inlet 12 at the top of the resin cavity 1, the water outlet 13 between the bottom of the resin cavity 1 and the water outlet 11, the water outlet 21 on the bottom side wall of the salt cavity 2, and the water inlet 22 at the connection part of the first water flow channel 402 and the top of the salt cavity 2 are all provided with filter grids. Specifically, the gaps between the filter grids at the water inlet 12 and the water outlet 13 of the resin chamber 1 are preferably set to be less than 0.5 mm for preventing the resin in the resin chamber 1 from being lost. In addition, the gap between the filtering grids at the water outlet 21 and the water inlet 22 of the salt chamber 2 is preferably set to be less than 0.2 mm for preventing the salt particles in the salt chamber 2 from losing, thereby playing an effective role in blocking and filtering.
