Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.

In the correlation technique, be provided with the water tank of water storage in most dish washer, and because dish washer is when using hot water washing tableware, atmospheric pressure in the vapor can increase dish washer inner bag, so can set up the respirator on the water tank, utilize the respirator to balance inner bag and the atmospheric pressure in the external world for dish washer can be safe normal work. The water stored in the water tank can be used for washing next time or next stage, and in order to save energy consumption, the washing water stored in the water tank can be preheated firstly and then is introduced into the inner container of the dish-washing machine for washing. However, if the water tank is used for storing water for a long time, the water tank is polluted due to the formation of scale in the water tank caused by the washing water with high hardness, so that the water tank is polluted, the water tank is seriously corroded and damaged due to perforation, and once the water tank is damaged, the whole dish washing machine cannot be used continuously.

In a first aspect, to solve the problem that the dishwasher cannot be used continuously due to the pollution of the water tank, referring to fig. 1, the present application provides a washing system of the dishwasher, which includes a respirator 10, a water softener 20, a water tank 30, a liner 40, a first on-off controller 50 and a second on-off controller 60.

Specifically, the respirator 10 has a water inlet pipe 11, the water inlet pipe 11 has a water inlet 12 and a first water outlet 13, the water inlet 12 of the respirator 10 can be connected with a water inlet valve 100, the water inlet valve 100 is connected with a water source, such as a municipal water pipe, and when the water inlet valve 100 is opened, the water source can supply water for a washing system through the water inlet valve 100. The inlet conduit 11 may be routed within the respirator 10 in a circuitous manner to increase the length of the inlet conduit 11 and reduce the amount of water that may back-flow in the inlet conduit 11 due to siphoning. During the washing process of the dishwasher 1, water can be heated to better wash dishes, but the vapor can increase the air pressure of the inner container 40 of the dishwasher 1, so the respirator 10 can be used to balance the pressure of the inner container 40 of the dishwasher 1 and the outside atmosphere, so as to ensure that the dishwasher 1 can be safely and normally used.

The water softener 20 has a raw water inlet 21 and a soft water outlet 22, the raw water inlet 21 is communicated with the first water outlet 13 of the respirator 10, and the washing water of the dishwasher 1 is introduced into the water softener 20 from the raw water inlet 21, softened by the water softener 20, and then discharged from the soft water outlet 22.

The total amount of calcium and magnesium ions contained in water is referred to as the hardness of water, and hard water is likely to form insoluble precipitates and adhere to the walls of the container, i.e., scale in daily life. For example: the water softener 20 can reduce the hardness of the washing water introduced into the water tank 30 or the inner tub 40 because the water softener 20 can cause scale formation in the water tank 30 or the inner tub 40, seriously hampers the flow of water, contaminates the water tank 30 or the inner tub 40, and causes corrosion damage to the water tank 30 or the inner tub 40 due to perforation. The water softener 20 is an ion exchange device, and calcium and magnesium ions in water are removed by using sodium cation exchange resin to achieve the purpose of softening hard water, so that the phenomenon that carbonate scales in the water tank 30 and the inner container 40 is avoided, the harm caused by scale is reduced, and the service life of the dish washing machine 1 is prolonged.

The water tank 30 and the respirator 10 are arranged in a split manner, so that the water tank 30 and the respirator 10 can work independently and the water tank 30 and the respirator 10 can be conveniently disassembled and assembled. If the water tank 30 in the dish washer 1 is damaged and needs to be replaced and maintained or the water tank 30 needs to be cleaned and temporarily cannot be used, a user does not need to reset each water inlet pipeline or each drainage pipeline in the dish washer 1, only the water softener 20 and the water tank 30 need to be disconnected or dismantled, the on-off of each pipeline of the dish washer 1 is adjusted, a washing system can continue to work normally, the use flexibility of the dish washer 1 is enhanced, and the dismounting and mounting process is simplified. After the water tank 30 is removed or disconnected, in the washing system, the washing water flows into the water softener 20 through the water inlet valve 100 and the respirator 10, and is softened by the water softener 20 to form soft water, and the soft water flows out through the soft water outlet 22 and directly flows into the inner container 40, so that the tableware in the inner container 40 is washed.

The water tank 30 has a water passage port 31, and the inner container 40 communicates with the water passage port 31. Wherein, only one water passage opening 31 of the water tank 30 is needed, and the water passage opening 31 can be used as a water inlet of the water tank 30 and also can be used as a water outlet of the water tank 30; the number of the water through openings 31 can be two, one water through opening 31 is used as a water inlet of the water tank 30, and the other water through opening 31 is used as a water outlet of the water tank 30; the number and position of the water passage ports 31 may be set according to actual conditions, and are not particularly limited. It can be understood that the inner container 40 is provided therein with a washing cavity for washing dishes, and the dishes are all located in the washing cavity of the inner container 40 during the washing process. The inner container 40 may be provided with a heater for heating water in the washing cavity, so that the water in the washing cavity may have a certain temperature, and the dishwasher 1 may obtain a high cleaning rate and a high drying rate in a short time. The washing water can be stored in the water tank 30, the water tank 30 is disposed near the inner container 40, so that heat generated by the inner container 40 when in use can be transferred to the water tank 30, preheating of the water stored in the water tank 30 is realized, and the water stored in the water tank 30 can be used for washing at the next time or at the next stage. In addition, the water tank 30 may be disposed in contact with the inner container 40, so that heat generated from the inner container 40 is more transferred to the water tank 30. The water tank 30 may be disposed higher than the inner container 40, so that the water tank 30 may be drained from the water tank 30 to the inner container 40 only by gravity without an additional connection of a drain pump.

Furthermore, the water opening 31 of the water tank 30 is communicated with the inner container 40, so that the preheated water flows from the water tank 30 to the inner container 40, the water temperature in the water tank 30 is higher than the water temperature of the washing water provided by the water source, and compared with the water source directly supplying water to the inner container 40, the water heater can reduce the power consumption required for heating the water in the inner container 40 and save energy. When the dishwasher 1 is in operation, the inner container 40 is in a non-heat-insulating state, so that heat of the inner container 40 can be transferred to the water tank 30 when the inner container 40 is in operation. In addition, a high thermal conductivity device can be arranged between the inner container 40 and the water tank 30 to improve the heat transfer efficiency between the two.

The first on-off controller 50 is arranged between the water through opening 31 of the water tank 30 and the inner container 40; the second on-off controller 60 is provided between the soft water outlet 22 of the water softener 20 and the water tank 30, or between the soft water outlet 22 of the water softener 20 and the inner bladder 40, i.e., the first on-off controller 50 may be provided between the water tank 30 and the inner bladder 40, and the second on-off controller 60 may be provided between the water softener 20 and the water tank 30, or the second on-off controller 60 may be provided between the water softener 20 and the inner bladder 40.

Specifically, the first on-off controller 50 and the second on-off controller 60 are arranged, so that the water source is supplied to the liner 40 through the respirator 10 and the water softener 20 under the matching of the two on-off controllers, or the water source is supplied to the water tank 30 through the respirator 10 and the water softener 20, or the water tank 30 is supplied to the liner 40. Switching between a plurality of water supply modes can be realized by controlling the two on-off controllers, and the control is simple and convenient and is easy to operate. In addition, since the water stored in the water tank 30 can exchange heat with the environment and absorb heat transferred from the inner container 40, the water temperature of the water stored in the water tank 30 is higher than the water temperature of the water softener 20 directly supplying water to the inner container 40, so that the energy consumption for heating the inner container 40 can be reduced when the water tank 30 supplies water to the inner container 40, and the energy-saving effect can be achieved.

Referring to fig. 1, in some embodiments of the present application, the first on-off controller 50 and the second on-off controller 60 are both shut-off valves.

Specifically, when the first on-off controller 50 is opened and the second on-off controller 60 is closed, the soft water outlet 22 of the water softener 20 is disconnected from the inner tub 40, and the soft water outlet 22 is communicated with the water tank 30, and the washing water from the water source can flow into the water softener 20 through the breather 10, and the soft water formed after being softened by the water softener 20 flows out through the soft water outlet 22 and is introduced into the water tank 30, in the process, the water storage of the water tank 30 is realized; when the first on-off controller 50 is closed and the second on-off controller 60 is opened, the soft water outlet 22 is disconnected from the water tank 30, the soft water outlet 22 is communicated with the inner container 40, and the washing water is directly introduced into the inner container 40 from the soft water outlet 22, so that the conventional water inlet of the dishwasher 1 is realized; when the first on-off controller 50 is opened and the second on-off controller 60 is opened, the water tank 30 is communicated with the inner container 40, and water in the water tank 30 flows into the inner container 40 under the action of gravity, so that the water tank 30 directly supplies water to the inner container 40, and in the process, the water inlet valve 100 can be closed.

It should be noted that, as shown in fig. 1, when the second cut-off controller 60 is positioned between the tub 40 and the water softener 20, the washing system of the dishwasher may include a main passage 27, a first branch passage 271, and a second branch passage 272. One end of the main passage 27 is connected to the soft water outlet 22 of the water softener 20, the other end of the main passage 27 is connected to one end of the first branch passage 271 and one end of the second branch passage 272, the other end of the first branch passage 271 is connected to the water passage port 31 of the water tank 30, the other end of the second branch passage 272 is connected to the inner container 40, the first on-off controller 50 is provided in the first branch passage 271, and the second on-off controller 60 is provided in the second branch passage 272.

It can be understood that, taking the first on-off controller 50 as an example of being opened and the second on-off controller 60 as an example, the main passage 27 is communicated with the first branch passage 271, and the washing water is introduced into the water tank 30 from the soft water outlet 22, in the process, the water storage of the water tank 30 is achieved; taking the first on-off controller 50 closed and the second on-off controller 60 open as an example, the main passage 27 is communicated with the second branch passage 272, and the washing water is introduced into the inner container 40 from the soft water outlet 22, so that the conventional water inlet of the dishwasher 1 is realized; taking the first on-off controller 50 as an example and the second on-off controller 60 as an example, the first branch passage 271 is communicated with the second branch passage 272, and the water in the water tank 30 is introduced into the inner container 40, so that the water stored in the water tank 30 is directly supplied to the inner container 40, and in the process, the water inlet valve 100 can be closed.

It should be noted that, in addition to the main passage 27, the first branch passage 271 and the second branch passage 272, the washing system may further include a third cut-off controller (not shown), which may be provided in the main passage 27, and is opened when the water softener 20 supplies water to the water tank 30 or the inner container 40; when the water tank 30 supplies water to the inner container 40, the third on-off controller is turned off. The third cut-off controller may include any device having a cut-off function, such as a cut-off valve, a water pump having a cut-off function, and the like.

Referring to fig. 2 and 3, in some embodiments of the present invention, the first on-off controller 50 is a cut-off valve, and when the cut-off valve is opened, the water passage opening 31 of the water tank 30 is communicated with the inner container 40; the second on-off controller 60 is a first direction change valve having a first state in which the soft water outlet 22 communicates with the water tank 30 and a second state that can be switched with each other; in the second state, the soft water outlet 22 communicates with the inner bladder 40.

Specifically, as shown in fig. 2, when the cut-off valve as the first on-off controller 50 is closed and the first direction valve as the second on-off controller 60 is in the first state, the soft water outlet 22 is communicated with the water tank 30, and the washing water is introduced into the water tank 30 from the soft water outlet 22; when the cut-off valve as the first on-off controller 50 is closed and the first direction valve as the second on-off controller 60 is in the second state, the soft water outlet 22 is communicated with the inner container 40, and the washing water is introduced into the inner container 40 from the soft water outlet 22; when the shut-off valve as the first on/off controller 50 is opened, the water tank 30 communicates with the inner tub 40, and the washing water is introduced from the water tank 30 into the inner tub 40. Wherein, water tank 30 is located the top of inner bag 40 water inlet, so the water in the water tank 30 can flow out under the dead weight effect, and need not additionally to set up structures such as pump, reduce cost reduces the complexity of control simultaneously.

As shown in fig. 2, the operation process of the washing system is as follows: in the initial washing state of the dishwasher 1, the stop valve is opened, the preheated water in the water tank 30 flows to the inner container 40, the stored water in the water tank 30 is filled before the last washing is finished, and the stored water in the water tank 30 is heated up due to the heat exchange with the environment because the storage time is sufficient, so that the energy consumption can be saved by initially putting the water tank 30 in; in the initial washing or a certain specific washing stage of the dishwasher 1, the cut-off valve is closed, the first reversing valve is in the first state, the washing water flows through the water softener 20 from the water inlet pipeline 11 and is introduced into the water tank 30, and because the dishwasher 1 is in a non-heat insulation state, the water stored in the water tank 30 is increased along with the temperature rise of the inner container 40, so that the water temperature is increased; in the rinsing or subsequent washing stage of the dishwasher 1, the block valve is opened, the preheating water in the water tank 30 flows to the inner container 40, and the water temperature stored in the water tank 30 is higher than the conventional water inlet water temperature, so that the energy consumption can be saved; before the washing of the dishwasher 1 is finished, the cut-off valve is closed, the first reversing valve is in the first state, the washing water from the water source flows through the respirator 10 and the water softener 20 to supplement the water to the water tank 30, and the condensation and drying effects can be further enhanced because the water tank 30 is in a low-temperature state compared with the inner container 40. Furthermore, the water stored in the water tank 30 is used for the next washing of the dishwasher 1, and the water temperature can be further increased when the storage time is sufficient, thereby effectively saving energy consumption.

In addition, when the water tank 30 is temporarily out of service for cleaning or maintenance, the washing system can still continue to work, and at this time, the water inlet process of the washing system is as follows: when the stop valve is closed and the first direction changing valve is in the second state, the washing water from the water source flows through the breather 10 and the water softener 20 and directly flows into the inner container 40, and the washing operation is performed on the tableware.

Further, referring to fig. 2, in some embodiments of the present invention, there are two water openings of the water tank, namely, the first water opening 32 and the second water opening 33, and the washing system includes a main water path 28, a first branch water path 281, a second branch water path 282 and a third branch water path 283, wherein the main water path 28 connects the soft water outlet 22 and the input end of the first directional control valve; the first branch water passage 281 is connected with the first output end of the first direction changing valve and the first water passage port 32; the second branch water passage 282 connects the second output end of the first direction valve and the inner container 40; the third branch water passage 283 connects the second water port 33 and the second branch water passage 282, and the second shut-off controller 60 is provided in the third branch water passage 283.

It is understood that, taking the example where the cut-off valve is closed and the first direction valve is in the first state, the main water path 28 communicates with the first branch water path 281, and the washing water is introduced into the water tank 30 from the soft water outlet 22, i.e., the water tank 30 stores the water. Taking the example of the shut-off valve being closed and the first directional control valve being in the second state, the main water passage 28 communicates with the second branch water passage 282, and the washing water is introduced into the inner tub 40 from the soft water outlet 22, i.e., the normal water supply. Similarly, for example, when the block valve is opened, the third branch water passage 283 communicates with the second branch water passage 282, and the washing water is introduced into the tub 40 from the water tank 30, that is, the water stored in the water tank 30 is directly introduced into the tub 40, and the on-off valve 100 may be closed in this process.

Referring to fig. 4, in some embodiments of the present invention, the water softener 20 includes a resin chamber 23, a regeneration chamber 24, and a switch valve 25, wherein the switch valve 25 connects the resin chamber 23 and the regeneration chamber 24, and the soft water outlet 22 is disposed in the resin chamber 23.

The resin chamber 23 functions to adsorb calcium and magnesium ions in water, soften water, and reduce the generation of scale. However, the long service life of the resin cavity 23 may cause the cavity wall of the resin cavity 23 to adsorb too many calcium and magnesium ions, so that the resin cavity 23 loses the adsorption effect, and therefore, the regeneration cavity 24 may be disposed in the water softener 20, and the principle of the regeneration cavity 24 is to use a large amount of sodium ions to exchange with the calcium and magnesium ions in the resin, so as to replace the calcium and magnesium ions on the cavity wall of the resin cavity 23, so that the inside of the resin cavity 23 is filled with sodium ions again, and the adsorption function of the resin cavity 23 is restored, so that the resin cavity 23 can be used continuously.

Referring to fig. 4 and 5, in some embodiments of the present invention, the water softener 20 further includes a second direction valve 26, and the raw water inlet 21 is switched to communicate with the regeneration chamber 24 or the resin chamber 23 through the second direction valve 26.

It is understood that the water inlet of the second direction valve 26 may be the raw water inlet 21 of the water softener 20, and the water outlet of the resin chamber 23 may be the soft water outlet 22 of the water softener 20.
