Description

Technical Field

[0001] The utility model belongs to the technical field of water purification equipment, and in particular relates to an embedded soft water purification equipment. Background Art

[0002] Since tap water contains metal ions such as calcium, magnesium, and iron, the water has a certain hardness. In order to reduce the hardness of water and remove metal ions such as calcium and magnesium in water, as living standards continue to improve, the use of water purification equipment with water softening function has gradually become popular in households, such as installing a whole-house water purification system. The existing softening of water quality is to use the functional ions of the resin to exchange with the calcium and magnesium ions in the water, thereby adsorbing the calcium and magnesium ions in the water to reduce the hardness of the water. However, when the resin adsorption reaches saturation, its adsorption capacity decreases, and the resin needs to be regenerated at this time. The resin regeneration process is to rinse the resin with salt water to replace the calcium and magnesium ions in the resin, so that the resin can restore the ability to soften water. The existing equipment uses a salt box to add water and solid salt to the salt box to form a certain concentration of salt water.

[0003] A conventional salt box is an elongated barrel with an opening on the top. Salt and water are added into the salt box through the opening. There are two ways to add water: the first is to add water manually, which brings great inconvenience to the user; the second is to connect the water inlet of the salt box to the resin tank. However, when the resin tank is in regeneration, the resin tank cannot produce soft water. When there is a shortage of water in the salt box, it is difficult to replenish water in time.

[0029] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The components of the embodiment of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figure 1-6 As shown, the utility model provides an embedded soft water purification device, including a housing 100, wherein a pre-filter 1, a resin tank 2, a salt box 3 and a filter element 4 are arranged in the housing 100, and the pre-filter 1 is provided with a water inlet pipe 11 and a water outlet pipe 12, wherein the water inlet pipe 11 is connected to the external raw water. In this embodiment, a raw water inlet 14 is provided on the housing 100, wherein the raw water inlet 14 is connected to a tap water pipe, and the water inlet pipe 11 is connected to the raw water inlet 14 through a water pipe, so that raw water enters the pre-filter 11, and large particles of impurities in the raw water are filtered, and the water after primary filtration by the pre-filter 11 is discharged from the water outlet pipe 12.

[0032] The resin tank 2 is provided with a water inlet 21, a first water outlet 22, a waste water outlet 23 and a salt absorption port 24. The water inlet 21 is connected to the water outlet pipe 12. The water after primary filtration flows into the resin tank 2 from the water inlet 21, and softened water is obtained after the softening treatment of the resin tank 2. The soft water flows out from the first water outlet 22. The first water outlet 22 is connected to the soft water output end for use by users. In this embodiment, a soft water outlet 25 is provided on the housing 100. The first water outlet 22 is connected to the soft water outlet 25, and the soft water outlet 25 is connected to the water use end.

[0033] The salt tank 3 is provided with a water inlet 31 and a liquid outlet 33, and the liquid outlet 33 is connected to the salt absorption port 23. When the resin tank 2 is in resin regeneration, the salt absorption port 23 is in a conducting state, and the first water outlet 22 is in a closed state. The salt water in the salt tank 3 flows out from the liquid outlet 33, and then flows into the resin tank 2 from the salt absorption port 23 to flush the resin in the resin tank 2. The waste water generated by the flushing flows out from the waste water outlet 24. The water inlet 21 is connected to the water outlet pipe 12. The water after primary filtration flows into the salt tank 3 through the water inlet 21 to replenish water or dissolve salt to form salt water. The use of water after primary filtration can greatly reduce impurities in the salt water, and avoid excessive impurities flowing into the resin tank 2 during the flushing of the resin tank 2 to cause mixing into soft water.

[0034] The water inlet end of the filter element 4 is connected to the water outlet pipe 12, and the water outlet end of the filter element 4 is connected to the user water end to provide purified filtered water to the user. In this embodiment, the filter element 4 can be a composite filter element or a combination of multiple filter elements, and the specific type of the filter element 4 is not limited.

[0035] The embedded soft water purification device of the utility model has the functions of producing soft water and purifying water. Compared with the existing water purification devices, users do not need to purchase multiple devices. In addition, the water filtered by the pre-filter is connected to the salt tank, and there is no need to manually add water from the water inlet. Water can also be replenished in any situation. For example, when the resin tank is in the regeneration working state, the salt tank is short of water or the salt concentration is too high, water can be directly replenished without being affected by the regeneration of the resin tank or the reduction of water production capacity, which greatly improves the user experience.

[0036] Furthermore, if Figure 1 and 3 As shown, a water connection pipe 6 is provided in the housing 100, and a water inlet 61, a second water outlet 62 and a third water outlet 63 are provided on the water connection pipe 6.

The liquid level sensor 32 is provided with a high water level detection point 321 and a low water level monitoring point 322, which are used to detect that the water level in the salt box 3 is too high or lacks water. When the liquid level sensor 32 detects that there is a lack of water in the salt box 3, an electrical signal is sent to the controller, and the controller controls the solenoid valve 311 to open and automatically add water to the salt box 3; during the water adding process, when the liquid level sensor 32 detects that the water level in the salt box 3 exceeds the highest water point, an electrical signal is sent to the controller, and the controller controls the solenoid valve 311 to close and stop adding water.

[0039] Specifically, the shell 100 is provided with a wastewater port 8 , and the salt box 3 is provided with an anti-overflow port 34 .

A through hole 721 is provided on the bottom plate 72, and the through hole 721 is communicated with the mounting cavity 75. The first side plate 73 and the second side plate 74 are both provided with a slot 741. The pre-filter 1 is built in the mounting cavity 75, and the water inlet pipe 11 and the water outlet pipe 12 are stuck in the slot 741, so that the pre-filter 1 is mounted on the bracket 7. In this embodiment, the pre-filter 1 passes through the through hole 721 so that the upper part is placed in the mounting cavity 75.

[0041] Specifically, at least two of the first side plates 73 and the second side plates 74 are provided, and a limiting groove 741 is formed between the two first side plates 73 or the second side plates 74. A limiting portion 13 is provided on the water inlet pipe 11 and / or the water outlet pipe 12, and the limiting portion 13 is located in the limiting groove 741, so that the pre-filter 1 can be more stably installed on the bracket 7. The embedded soft water purification device of the utility model can choose to set the limiting portion 13 on the water inlet pipe 11 or the water outlet pipe 12 according to actual conditions.

[0042] In this embodiment, two of the first side panels 73 and two of the second side panels 74 are provided, and correspondingly, two of the limiting grooves 741 are also provided, and limiting portions 13 are provided on the water inlet pipe 11 and the water outlet pipe 12 .
