Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of water softener, and the utility model further relates to a cleaning machine using the water softener. BACKGROUND

[0002] The existing dishwasher usually has softening function, that is, using water softener to soften domestic water before entering the dishwasher to clean tableware. The water softener can reduce water hardness, prevent Ca and Mg ions from remaining in water, ensure the cleanliness of tableware, and prevent scale and rust from forming in the inner tank of the dishwasher.

[0003] The water softener usually includes a salt chamber and a resin chamber. Ion exchange resin is usually used in the resin chamber to soften water. After a certain period of softening, the ion exchange resin reaches a "saturation" state of calcium and magnesium ions. At this time, the ion exchange resin needs to be regenerated by softening salt to release waste water containing Ca and Mg ions. The salt water in the resin chamber can regenerate the ion exchange resin in the resin chamber, and then soften the water.

[0004] Currently, the resin chamber has the following problems: 1. The resin is in a dispersed state, and the resin chamber usually has a certain gap, which causes the resin to be washed and accumulated by the water flow during water softening, forming a path without water. The water will preferentially enter these paths without passing through the resin, resulting in unsatisfactory softening effect. The softening capacity of the existing water softener is less than half of the ideal state, which is one of the main reasons. 2. During the replacement of the water softener, tap water is usually introduced into the salt chamber, and the pressure generated by the increase in volume is used to press the salt water into the resin chamber to achieve the purpose of resin replacement. However, the salt water pressed into the resin chamber usually mixes with tap water, resulting in insufficient saturation of the salt water entering the resin chamber and poor replacement effect. SUMMARY

[0005] The first technical problem to be solved by the utility model is to provide a water softener that reduces the formation of water-washed resin paths and ensures softening and replacement effect.

[0006] The second technical problem to be solved by the utility model is to provide a cleaning machine using the aforementioned water softener.

[0007] The technical solution adopted by the utility model to solve the aforementioned first technical problem is as follows: a water softener includes a shell with a salt chamber and a resin chamber. The resin chamber is characterized by at least two partitions between the water inlet end and the water outlet end. The partitions separate the resin chamber into a continuous S-shaped curved flow path.

[0008] Preferably, a shunt passage for connecting a water source is arranged in the shell, a first shunt opening for communicating with the salt cavity and a second shunt opening for communicating with the resin cavity are arranged on the shunt passage, and a switching valve for switching the first shunt opening and the second shunt opening is arranged in the shunt passage; the salt cavity is communicated with the resin cavity through a communication opening, and a one-way valve is arranged on the communication opening of the salt cavity for communicating with the resin cavity.

[0009] In order to further ensure the flowability of water and improve the contact degree of water and resin, a plurality of water-permeable holes are uniformly distributed on the partition plate.

[0010] In order to facilitate the control of the salt adding amount, a salt adding opening is arranged on the top of the shell corresponding to the salt cavity, and a detector for detecting the salt adding amount is arranged in the salt cavity corresponding to the position of the salt adding opening.

[0011] Preferably, the detector is a photosensitive sensor.

[0012] In order to ensure the accuracy of detection, the photosensitive sensor is provided with at least two.

[0013] In order to avoid the interference of the flow in the salt cavity on the salt detection, a baffle with a height lower than that of the salt cavity is arranged around the detector.

[0014] In order to ensure the saturation degree of the brine entering the resin cavity, a drainage flow channel extending from the water inlet end to the area inside the baffle is arranged in the salt cavity.

[0015] Preferably, the drainage flow channel is formed in the bottom of the salt cavity.

[0016] The technical solution adopted by the utility model to solve the second technical problem is: a cleaning machine, which comprises an inner container with a cleaning cavity, characterized in that: it further comprises a water softener as described above, and the inner container is connected with the water outlet end of the resin cavity.

[0017] Compared with the prior art, the utility model has the advantages that: the water softener in the utility model is provided with a plurality of partition plates in the resin cavity, thereby isolating the space in the resin cavity to form a continuous S-shaped path, so that the water flow path from the water inlet end to the water outlet end of the resin cavity is longer, the contact degree of water / brine and resin is strengthened, and the softening and replacement treatment of water is more beneficial.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figs. 1 to 3 As shown, the water softener in this embodiment includes a housing 1. To facilitate structural assembly, this embodiment includes a lower housing 1 and an upper cover that fit together.

[0023] The housing 1 has a salt chamber 11, a resin chamber 12 and a diversion channel 13 located between the salt chamber 11 and the resin chamber 12. A salt inlet 14 is provided on the housing 1 at the position corresponding to the salt chamber 11. A cover is provided on the salt inlet 14. The resin chamber 12 is filled with resin for softening water.

[0024] The diversion channel 13 is used to connect to the water source. The diversion channel 13 has a first diversion port 131 connected to the brine chamber 11 and a second diversion port 132 connected to the resin chamber 12. The diversion channel 13 is equipped with a switching valve 3 that switches between the first diversion port 131 and the second diversion port 132. During use, the position of the switching valve 3 is switched so that tap water entering from the diversion channel 13 enters the brine chamber 11 through the first diversion port 131 or the resin chamber 12 through the second diversion port 132.

[0025] The brine chamber 11 and resin chamber 12 are relatively isolated. To facilitate the introduction of tap water entering through the diversion channel 13 into the brine chamber 11 and resin chamber 12, a diversion channel 111 is typically provided corresponding to the brine chamber 11, and a diversion channel 121 is provided corresponding to the resin chamber 12. The inlet of the diversion channel 111 is connected to the first diversion port 131, and the inlet of the diversion channel 121 is connected to the second diversion port 132. During operation, if the softening salt is being dissolved, the switching valve 3 is activated to connect the diversion channel 13 and the brine chamber 11, allowing water to flow into the brine chamber 11. If the water is being softened, the switching valve 3 is activated to connect the diversion channel 13 and the resin chamber 12, allowing the resin in the resin chamber 12 to soften the incoming water and form softened water.

[0026] In addition, the brine chamber 11 is connected to the resin chamber 12 via a connecting port, and a one-way valve is provided on the connecting port from the brine chamber 11 to the resin chamber 12. When it is necessary to pressurize the brine in the brine chamber 11 into the resin chamber 12 for resin replacement, the switching valve 3 is activated to introduce tap water into the brine chamber 11. The pressure in the brine chamber 11 increases, and the brine in the brine chamber 11 is pressed into the resin chamber 12 through the one-way valve, thereby achieving the replacement of the resin in the resin chamber.

[0027] In addition, in order to further ensure the water flowability and improve the contact degree of water and resin, the plurality of water-permeable holes 21 are uniformly distributed on the partition plate 2, and the water in the paths on both sides of one partition plate 2 can also permeate each other.

[0028] In addition, in order to further ensure the water flowability and improve the contact degree of water and resin, the plurality of water-permeable holes 21 are uniformly distributed on the partition plate 2, and the water in the paths on both sides of one partition plate 2 can also permeate each other.

[0029] The salt water for replacing the resin has certain concentration requirements, and in order to better control the salt water concentration in the salt chamber 11, the amount of salt added needs to be accurately controlled. In the embodiment, in order to facilitate the control of the amount of salt added, a salt adding opening 14 is arranged on the top of the shell 1 corresponding to the salt chamber 11, and a detector 4 for detecting the amount of salt added is arranged in the salt chamber 11 corresponding to the position of the salt adding opening 14, that is, the detector 4 is arranged below the salt adding opening 14. The detector 4 in the embodiment adopts a photosensitive sensor. When salt is added, the salt will cover the photosensitive sensor, and the brightness detected by the photosensitive sensor will also change. In the embodiment, when the amount of salt covering the photosensitive sensor reaches a set amount, a reminder will be triggered, and the amount of salt added at this time can ensure that the concentration of the generated salt water in the salt chamber 11 reaches the required saturation state. In order to ensure the accuracy of detection, the photosensitive sensor is provided with at least two.

[0030] In addition, the detector 4 is provided with a baffle 5 with a height lower than that of the salt chamber 11. Based on the shielding of the baffle 5, the amount of salt water covering the photosensitive sensor when the salt water in the salt chamber 11 shakes can be avoided, and the interference of water flow in the salt chamber 11 on salt detection can be avoided. At the same time, based on the baffle 5, salt can also be accumulated on the photosensitive sensor, improving the accuracy of detection. The baffle 5 can also effectively avoid the influence of other external light on the photosensitive sensor.

[0031] In order to ensure the saturation degree of the brine entering the resin cavity 12, the salt cavity 11 is provided with a drainage flow channel 111 extending from the water inlet end to the area surrounded by the baffle 5, the drainage flow channel 111 is a space independent of the water in the salt cavity 11, and only communicates with the water in the salt cavity 11 in the area surrounded by the baffle 5. The drainage flow channel 111 in the embodiment is formed in the bottom of the salt cavity 11. In this way, when it is needed to press the water in the salt cavity 11 into the resin cavity 12 to replace the resin, the water added into the salt cavity 11 through the shunt channel 13 enters the area surrounded by the baffle 5 through the drainage flow channel 111, and does not diffuse into the salt cavity 11 at the inlet position, so that the saturation degree of the brine pressed into the resin cavity 12 from the salt cavity 11 is ensured, and the replacement effect of the resin in the resin cavity 12 is ensured.

[0032] The softener in the utility model, a plurality of partitions 2 are arranged in the resin cavity 12, and the space in the resin cavity 12 is isolated to form a continuous S-shaped path, so that the water flow path from the water inlet end to the water outlet end of the resin cavity 12 is longer, the contact degree of water / brine and resin is strengthened, and the softening and replacement treatment of water is more beneficial. At the same time, based on the partition 2 structure, the water entering the resin cavity 12 is guided, the situation that the water washes the resin to form a path is reduced, and the softening and replacement effect is improved.

[0033] The utility model also relates to a kind of cleaning machines, including the inner container with cleaning cavity, and the softener described above, inner container is connected with the water outlet end of resin cavity 12. In this way, the water softened by resin in resin cavity 12 is output to the inner container, and then the cleaning of the object to be cleaned is carried out in the inner container, reducing the scale situation in the washing process.
