Description

Technical Field

[0001] This utility model relates to the field of water softening equipment technology, and more specifically to a water softener and a dishwasher. Background Technology

[0002] Dishwashers typically use tap water for washing dishes, but tap water often contains a high amount of calcium carbonate and magnesium carbonate ions. During the washing process, these ions react with detergent ingredients and dirt, producing a difficult-to-remove precipitate that reduces the dishwasher's washing effectiveness. Simultaneously, these precipitates can clog the inside of the dishwasher, affecting its lifespan. Therefore, most dishwashers are equipped with a water softener, which softens tap water before it enters the dishwasher's cavity to wash dishes.

[0003] However, existing dishwasher water softeners generally only have a single resin chamber. Domestic water flows into the water softener through the inlet, passes through a filter at the bottom of the resin chamber, and then flows out through another filter at the top of the resin chamber to the water softener outlet. The softening path length of the water is limited, meaning that the contact time between the water and the ion exchange resin is short, which limits the water softening effect of the water softener. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a water softener and a dishwasher that can improve the water softening capacity of the water softener.

[0005] The technical solution adopted by this utility model to solve its technical problem is: the water softener includes a resin chamber;

[0007] This technical solution provides a water softener that connects the two resin chambers by dividing them into two and setting a water passage chamber. This extends the distance the water flows through the resin chamber and increases the contact time between the water and the ion exchange resin, thereby improving the water softener's softening capacity. At the same time, due to the enhanced softening capacity, the amount of resin used in the water softener can be optimized and reduced, achieving the effect of increasing efficiency and reducing costs.

[0014] In a preferred embodiment, the housing is further provided with a salt chamber and a one-way valve; the salt chamber is connected to the water inlet via a solenoid valve, and the salt chamber is also connected to the first water inlet chamber via a one-way valve.

[0015] In a preferred embodiment, a water inlet channel is formed between the top cover and the shell, one end of the water inlet channel is connected to the water inlet, and the other end is connected to the first water inlet chamber through a solenoid valve; the water inlet channel is arranged around the cavity wall of the upper part of the resin cavity.

Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0032] Reference Figure 1-6 This invention describes a water softener and a dishwasher according to an embodiment of the present invention. The water softener can be applied to dishwashers that require soft water.

[0033] In one embodiment, such as Figure 1-6 As shown, a water softener includes a resin chamber 11;

[0034] A partition 110 is provided in the resin cavity 11, which divides the resin cavity 11 into a first resin cavity 111 and a second resin cavity 112. A hollow column is provided in the middle of the partition 110, and the inner cavity of the column forms a water passage cavity 113.

[0035] The lower part of the first resin chamber 111 is connected to the water inlet 22 through the solenoid valve 13. The upper part of the first resin chamber 111 is connected to one end of the water chamber 113. The other end of the water chamber 113 is connected to the lower part of the second resin chamber 112. The upper part of the second resin chamber 112 is connected to the water outlet 12.

[0036] The water softener includes a housing 1, an upper cover 2, and a lower cover 3, with the upper cover 2 and the lower cover 3 respectively fastened to the upper and lower ends of the housing 1; the resin chamber 11 is a cylindrical inner cavity located inside the housing 1; the housing 1 can be an integrally molded structure integrating the resin chamber 11 and the outlet 12; the solenoid valve 13 can be installed on the housing 1 to control the connection between the inlet 22 and the first resin chamber 111; the inlet 22 can be located on the upper cover 2; the partition 110 can be vertically arranged, inclined, or horizontally arranged.

[0037] Specifically, the first state of the solenoid valve 13 can be either a de-energized state or an energized state. In this embodiment, the de-energized state of the solenoid valve 13 is set as its first state, and the energized state is set as its second state. When the solenoid valve 13 is in the first state (de-energized), the lower part of the first resin chamber 111 can be directly connected to the water inlet 22, and the water flow directly flows through the water inlet 22, the first resin chamber 111, the water passage chamber 113, and the second resin chamber 112 to the water outlet 12.

[0038] The working principle of the above water softener is as follows: Figure 3 As shown by the middle arrow, the water flow direction is such that the water entering through the inlet 22 flows into the lower part of the first resin chamber 111, flows out from the upper part of the first resin chamber 111 into the water passage chamber 113 inside the column, flows through the water passage chamber 113 to the lower part of the second resin chamber 112, and finally flows from the upper part of the second resin chamber 112 to the outlet 12. That is, the water first flows through the first resin chamber 111 and then through the second resin chamber 112. This doubles the distance the water flows through the resin chamber 11 while keeping the volume of the resin chamber 11 unchanged, thereby improving the water softening capacity of the water softener.

[0039] The water softener provided in this embodiment achieves communication between the resin chambers by dividing the resin chamber 11 into two and setting a water passage chamber 113. This extends the distance the water flows through the resin chamber 11 and increases the contact time between the water and the ion exchange resin, thereby improving the water softening capacity of the water softener. At the same time, due to the enhanced water softening capacity, the amount of resin used in the water softener can be optimized and reduced, achieving the effect of increasing efficiency and reducing costs.

[0040] In this embodiment, the lower end of the resin cavity 11 is provided with a first filter screen 14 and the upper end is provided with a second filter screen 15;

[0041] Half of the first filter 14 is located at the bottom of the first resin chamber 111, and the other half is located at the bottom of the second resin chamber 112; half of the second filter 15 is located on the top surface of the first resin chamber 111, and the other half is located on the top surface of the second resin chamber 112.

[0042] Specifically, such as Figure 3 As shown by the middle arrow, when the water softener is working, water enters the first resin chamber 111 through half of the first filter screen 14, then flows out through half of the second filter screen 15, passes through the water chamber 113, flows into the second resin chamber 112 through the other half of the first filter screen 14, and finally flows out to the outlet 12 through the other half of the second filter screen 15.

[0043] The first filter screen 14 is used to intercept impurities in the incoming water, and the other half is used to filter the water flowing from the first resin chamber 111 into the second resin chamber 112 to prevent resin from flowing out of the first resin chamber 111; the second filter screen 15 is used to intercept resin impurities in the outgoing water to prevent resin particles from entering water pipes or water-using equipment and to prevent water pollution.

[0044] In this embodiment, the first filter screen 14 and the second filter screen 15 are integrally formed or snap-fitted at both ends of the resin cavity 11. When the first filter screen 14 and the second filter screen 15 are integrally formed with the resin cavity 11, the structural strength can be improved, and the product structure is simple and the cost is low. When the first filter screen 14 and the second filter screen 15 are snap-fitted at the top and bottom of the resin cavity 11, the structure is simple and easy to install and disassemble.

[0045] In a specific implementation, one of the first filter screen 14 and the second filter screen 15 can be integrally formed with the resin cavity 11, while the other filter screen is snapped onto one end of the resin cavity 11. Taking the second filter screen 15 snapped onto the top of the resin cavity 11 as an example, the second filter screen 15 can be removed from one end of the resin cavity 11 to replace the ion exchange resin inside the resin cavity 11.

[0046] In this embodiment, both the first filter screen 14 and the second filter screen 15 are provided with a plurality of through holes to facilitate water flow. In specific implementation, the through holes can be strip-shaped, circular, elliptical, or other shapes, and this embodiment does not limit them.

[0047] In this embodiment, the water softener includes a housing 1 and an upper cover 2 and a lower cover 3 located at both ends of the housing 1; the resin chamber 11 and the water outlet 12 are located on the housing 1, and the water inlet 22 is located on the upper cover 2. The structure is simple and convenient for installation and maintenance.

[0048] In this embodiment, the upper cover 2 and the shell 1 form a water outlet cavity. The bottom of the upper cover 2 is provided with an upper partition 21, which divides the water outlet cavity into a first water outlet cavity 211 and a second water outlet cavity 212. The lower cover 3 and the shell 1 form a water inlet cavity. The upper part of the lower cover 3 is provided with a lower partition 31, which divides the water inlet cavity into a first water inlet cavity 311 and a second water inlet cavity 312.

[0049] The inlet 22 is connected to the first inlet chamber 311 via the solenoid valve 13. The first inlet chamber 311 is connected to the lower part of the first resin chamber 111. The upper part of the first resin chamber 111 is connected to the first outlet chamber 211. The first outlet chamber 211 is connected to one end of the water chamber 113. The other end of the water chamber 113 is connected to the second inlet chamber 312. The second inlet chamber 312 is connected to the lower part of the second resin chamber 112. The upper part of the second resin chamber 112 is connected to the second outlet chamber 212. The second outlet chamber 212 is connected to the outlet 12.

[0050] The above embodiment uses an upper partition 21 and a lower partition 31 on the upper cover 2 and the lower cover 3 to separate the water outlet chamber and the water inlet chamber, which is simple in structure and easy to assemble.

[0051] In this embodiment, the housing 1 is also provided with a salt chamber and a one-way valve; the salt chamber is connected to the water inlet 22 through the solenoid valve 13, and the salt chamber is also connected to the first water inlet chamber 311 through the one-way valve.

[0052] The second state of the solenoid valve 13 is the energized state. Specifically, since the first water inlet chamber 311 is connected to the lower part of the first resin chamber 111, when the solenoid valve 13 is in the second state (energized), the water inlet 22 is connected to the lower part of the first resin chamber 111 through the salt chamber and the check valve in sequence, thereby forming the resin regeneration water circuit of the water softener. Specifically, the above-mentioned water softener can switch between the two states of water softening and resin regeneration by switching the state of the solenoid valve 13.

[0053] In the above embodiments, by setting up a salt chamber and a one-way valve, and switching the state of the solenoid valve 13, the resin regeneration function can be realized, extending the service life of the water softener.

[0054] In this embodiment, a water inlet channel 23 is also formed between the upper cover 2 and the housing 1. One end of the water inlet channel 23 is connected to the water inlet 22, and the other end is connected to the first water inlet chamber 311 through the solenoid valve 13. The water inlet channel 23 is arranged around the cavity wall of the upper part of the resin cavity 11.

[0055] The above-mentioned water softener makes the product structure more compact and concentrated by setting the water inlet channel 23 around the upper cavity wall of the resin cavity 11, thereby further reducing the product volume.

[0056] In another embodiment, the present invention provides a dishwasher that includes a water softener as described in any of the above embodiments, which can extend the contact distance between the water flow and the ion exchange resin, thereby enhancing the water softening effect.

[0057] The dishwasher may include an inner tank, a drainage system, and the aforementioned water softener. The drain outlet of the inner tank is connected to the drainage system, and the inlet of the inner tank is connected to the outlet of the water softener.

[0058] Other components and operations of the water softener and dishwasher according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.
