Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to a water purifier. Background Art

[0002] For ordinary household reverse osmosis water purifiers, the flow rate is generally within 800 gallons, and water purification products with a flow rate of 1200 gallons have also emerged in related technologies. For water purification products with a flow rate of 1200 gallons, the water production flow rate can reach 3 L / min, which can meet the usage requirements of most scenarios for ordinary families. In the field of commercial water purifiers, due to the limitations of the filter element specifications and the power of the booster pump, it is very difficult to directly increase the water production capacity of the whole machine. The solution in the industry to solve the problem of large-flow water supply is to add a pressure bucket for water supply. The purified water produced by the whole machine water production system is stored in the pressure bucket, and the pressure bucket supplies water when the user takes water. In this way, the flow rate when the user takes water can be much larger than the water production flow rate of the whole machine, and large-flow water intake can be realized with a water purification system with a low gallonage.

[0003] When facing the complex and changeable usage requirements in commercial scenarios, this solution still has a great possibility of facing the situation of insufficient water volume. That is, after long-term large-flow water intake, the stored water in the pressure bucket is exhausted, and the water production system cannot replenish water to the pressure bucket in a timely and efficient manner, which will lead to the stagnation of water intake and affect the user experience. There are obviously two solutions to improve this aspect of the experience. One solution is to increase the volume of the pressure bucket to achieve more water storage, and the other solution is to increase the flow rate specification of the whole water production system so that it can replenish water to the pressure bucket more timely and efficiently when the water volume in the pressure bucket is insufficient. Increasing the volume of the pressure bucket will inevitably be accompanied by a change in the volume of the whole machine. Therefore, increasing the water production flow rate of the whole water production system is of more important significance for improving the user experience of the whole machine. Content of the Utility Model

[0004] In view of this, the utility model provides a water purifier to increase the water production flow rate.

[0005] The utility model provides a water purifier, comprising:

[0006] A first water production system, having a first water production end;

[0007] A second water production system, connected in parallel with the first water production system, having a second water production end;

[0008] A pressure bucket, simultaneously communicating with the first water production end and the second water production end;

[0009] A water intake port, simultaneously communicating with the first water production end, the second water production end and the pressure bucket.

[0010] Beneficial effects: When the whole machine makes water, the first water-making system and the second water-making system make water simultaneously. The purified water prepared by the first water-making system flows through the first water production end into the pressure barrel for storage, and the purified water prepared by the second water-making system flows through the second water production end into the pressure barrel for storage. Since the first water-making system and the second water-making system can make water simultaneously, the upper limit of the water-making flow rate of the whole machine can be greatly improved. The first water production end of the first water-making system is connected to both the pressure barrel and the water intake port at the same time, and the second water production end of the second water-making system is connected to both the pressure barrel and the water intake port at the same time. When the pressure in the pressure barrel is greater than the set water replenishment pressure threshold, when the user takes water, neither the first water-making system nor the second water-making system works, and the pressure barrel supplies water alone. When the pressure in the pressure barrel is lower than the preset water replenishment pressure threshold, both the first water-making system and the second water-making system work to replenish water to the pressure barrel. At this time, if water is taken, the whole machine is directly supplied with water by the first water-making system and the second water-making system, with a relatively large water-making flow rate. If the water intake flow rate is lower than the water-making flow rate, the excess flow will enter the pressure barrel for storage.

[0011] Specifically, by connecting the first water-making system and the second water-making system in parallel, if both the first water-making system and the second water-making system use 800-gallon filter elements, a water-making effect of 1600 gallons for the whole machine can be achieved. If both the first water-making system and the second water-making system use 1200-gallon filter elements, a water-making effect of 2400 gallons for the whole machine can be achieved. Therefore, it has a relatively large water-making flow rate.

[0012] In addition, since large-flow water production can be achieved by using low-specification filter elements, a low-flow-specification booster pump can be used in a supporting manner, which is also beneficial to the control of the volume of the whole machine, the control of the noise of the whole machine, and the control of vibration.

[0013] In an optional implementation manner, the first water-making system includes:

[0014] A first filter element having a first water inlet end and a first water outlet end;

[0015] A first reverse osmosis filter element, the water inlet of which is connected to the first water outlet end of the first filter element, and the pure water port of which is connected to the first water production end;

[0016] A first booster pump disposed between the first water outlet end and the water inlet of the first reverse osmosis filter element.

[0017] Beneficial effects: When the first water-making system makes water, water first enters the first filter element for purification. After the purified water flows out from the first water outlet end, it is pressurized by the first booster pump and then enters the first reverse osmosis filter element for purification.

[0018] In an alternative embodiment, the first filter element further has a second water inlet end and a second water outlet end. The pure water port of the first reverse osmosis filter element is communicated with the second water inlet end, and the second water outlet end is communicated with the first water production end.

[0019] Beneficial effects: When the first water production system produces water, water first enters the first filter element for purification. After the purified water flows out from the first water outlet end, it is pressurized by the first booster pump and then enters the first reverse osmosis filter element for purification. Then, it flows through the second water inlet end to the first filter element for purification again. After the purified water flows out from the second water outlet end, it flows through the first water production end to the pressure bucket or the water intake port.

[0020] In an alternative embodiment, the first water production system further includes a first water circuit board, and the first filter element and the first reverse osmosis filter element are both connected to the first water circuit board.

[0021] Beneficial effects: By providing the first water circuit board, it is convenient to install the first filter element and the first reverse osmosis filter element, and at the same time, the number of water pipes can be reduced.

[0022] In an alternative embodiment, the second water production system includes:

[0023] A second filter element having a third water inlet end and a third water outlet end;

[0024] A second reverse osmosis filter element, the water inlet of the second reverse osmosis filter element is communicated with the third water outlet end, and the pure water port of the second reverse osmosis filter element is communicated with the second water production end;

[0025] A second booster pump provided between the third water outlet end and the water inlet of the second reverse osmosis filter element.

[0026] Beneficial effects: When the second water production system produces water, water first enters the second filter element for purification. After the purified water flows out from the second water outlet end, it is pressurized by the second booster pump and then enters the second reverse osmosis filter element for purification.

[0027] In an alternative embodiment, the second filter element further has a fourth water inlet end and a fourth water outlet end. The pure water port of the second reverse osmosis filter element is communicated with the fourth water inlet end, and the fourth water outlet end is communicated with the second water production end.

[0028] Beneficial effects: When the second water production system produces water, water first enters the second filter element for purification. After the purified water flows out from the second water outlet end, it is pressurized by the second booster pump and then enters the second reverse osmosis filter element for purification. Then, it flows through the fourth water inlet end to the second filter element for purification again. After the purified water flows out from the fourth water outlet end, it flows through the second water production end to the pressure bucket or the water intake port.

[0029] In an alternative embodiment, the second water purification system further includes a second water circuit board, and both the second filter element and the second reverse osmosis filter element are connected to the second water circuit board.

[0030] Beneficial effects: By providing the second water circuit board, it is convenient to install the second filter element and the second reverse osmosis filter element, and at the same time, the number of water pipes can be reduced.

[0031] In an alternative embodiment, the water purifier further includes a water circuit board bracket, and the first water circuit board and the second water circuit board are fixed to the water circuit board bracket.

[0032] Beneficial effects: By providing the water circuit board bracket, both the first water circuit board and the second water circuit board are fixed to the water circuit board bracket, which is convenient for installing the first water circuit board and the second water circuit board.

[0033] In an alternative embodiment, the water purifier includes a housing, and the water circuit board bracket is disposed inside the housing.

[0034] Beneficial effects: The water purifier includes a housing, and the water circuit board bracket is disposed inside the housing. Therefore, both the first water circuit board and the second water circuit board are located inside the housing, and the housing can protect other components.

[0035] In an alternative embodiment, the housing is provided with a pump box, the pump box is provided with a sound-absorbing structure, and the first booster pump and the second booster pump are disposed inside the pump box.

[0036] Beneficial effects: By providing the pump box and the sound-absorbing structure in the pump box, it can play a role in noise reduction and reduce the noise of the whole machine. In addition, both the first booster pump and the second booster pump are disposed inside the pump box, making the structure more compact.

[0037] In an alternative embodiment, a third filter element is provided between the pressure bucket and the water intake.

[0038] Beneficial effects: Since when the pressure in the pressure bucket is greater than the set water replenishment pressure threshold, when the user takes water, both the first water purification system and the second water purification system do not work, and the pressure bucket supplies water alone. The water stored in the pressure bucket may produce peculiar smells and breed bacteria after long-term storage. Therefore, by providing a third filter element between the pressure bucket and the water intake, the water in the pressure bucket can be purified again to ensure reliable water use.

Specific embodiments

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0046] Ordinary household reverse osmosis water purifiers generally have a flow rate within 800 gallons, and related technologies have also produced water purification products with a flow rate of 1200 gallons. For water purification products with a flow rate of 1200 gallons, the water production flow rate can reach 3 L / min, which can meet the usage requirements of ordinary families in most scenarios. In the field of commercial water purifiers, due to the limitations of the filter element specifications and the power of the booster pump, it is very difficult to directly increase the water production capacity of the whole machine. The solution to large-flow water supply in the industry is to add a pressure bucket for water supply. The purified water produced by the whole machine water production system is stored in the pressure bucket, and the pressure bucket supplies water when the user takes water. In this way, the flow rate when the user takes water can be much larger than the water production flow rate of the whole machine, and large-flow water intake can be achieved with a water purification system with a low gallonage.

[0047] When facing the complex and changeable usage requirements in commercial scenarios, this solution is still very likely to face the situation of insufficient water volume. That is, after long-term large-flow water intake, the stored water in the pressure bucket is exhausted, and the water production system cannot replenish the pressure bucket in a timely and efficient manner, which will lead to the stagnation of water intake and affect the user experience. There are obviously two solutions to improve this aspect of the experience. One solution is to increase the volume of the pressure bucket to achieve more water storage, and the other solution is to increase the flow rate specification of the entire water production system so that it can replenish the pressure bucket more timely and efficiently when the water volume in the pressure bucket is insufficient. Increasing the volume of the pressure bucket will inevitably be accompanied by changes in the volume of the whole machine. Therefore, increasing the water production flow rate of the entire water production system is of more important significance for improving the user experience of the whole machine.

[0048] The following will describe the embodiments of the present invention in conjunction with Figures 1 to 3 ,

[0049] According to an embodiment of the present invention, a water purifier is provided, which includes a first water production system, a second water production system, a pressure bucket 8, and a water intake port.

[0050] Among them, the first water production system has a first water production end; the second water production system is connected in parallel with the first water production system, and the second water production system has a second water production end; the pressure bucket 8 is simultaneously connected to the first water production end and the second water production end; the water intake port is simultaneously connected to the first water production end, the second water production end, and the pressure bucket 8.

[0051] In this embodiment, when the whole machine makes water, the first water-making system and the second water-making system make water simultaneously. The purified water prepared by the first water-making system flows through the first water production end into the pressure bucket 8 for storage, and the purified water prepared by the second water-making system flows through the second water production end into the pressure bucket 8 for storage. Since the first water-making system and the second water-making system can make water simultaneously, the upper limit of the water-making flow rate of the whole machine can be greatly improved. The first water production end of the first water-making system is connected to both the pressure bucket 8 and the water intake port, and the second water production end of the second water-making system is connected to both the pressure bucket 8 and the water intake port. When the pressure in the pressure bucket 8 is greater than the set water replenishment pressure threshold, when the user takes water, neither the first water-making system nor the second water-making system works, and the pressure bucket 8 supplies water alone. When the pressure in the pressure bucket 8 is lower than the preset water replenishment pressure threshold, both the first water-making system and the second water-making system work to replenish water to the pressure bucket 8. At this time, if water is taken, the whole machine is directly supplied with water by the first water-making system and the second water-making system, with a relatively large water-making flow rate. If the water intake flow rate is lower than the water-making flow rate, the excess flow will enter the pressure bucket 8 for storage.

[0052] Specifically, by making the first water-making system and the second water-making system in parallel, if both the first water-making system and the second water-making system use 800-gallon filter elements, a water-making effect of 1600 gallons for the whole machine can be achieved. If both the first water-making system and the second water-making system use 1200-gallon filter elements, a water-making effect of 2400 gallons for the whole machine can be achieved.

[0053] In addition, since large-flow water production can be achieved by using low-specification filter elements, a low-flow booster pump can be used in a supporting manner, which is also beneficial to the control of the volume, noise, and vibration of the whole machine.

The first purified water pipe 12 and the second purified water pipe 13 are in parallel and then converge into the main purified water pipe and flow to the pressure bucket 8 for storage. When the pressure in the pressure bucket 8 is greater than the set water replenishment pressure threshold, when the user takes water, both the first water production system and the second water production system do not work, and the pressure bucket 8 supplies water alone. When the pressure in the pressure bucket 8 is lower than the preset water replenishment pressure threshold, both the first water production system and the second water production system work to replenish water to the pressure bucket 8. At this time, if water is taken, the whole machine is directly supplied with water by the first water production system and the second water production system, with a relatively large water production flow rate. If the water intake flow rate is lower than the water production flow rate, the excess flow will enter the pressure bucket 8 for storage.
