Description

Technical Field

[0001] The invention relates to water purification equipment, in particular to water purification equipment with a concentrated water tank water inlet arranged above. Background Art

[0002] Existing household water purification equipment usually uses ultrafiltration membrane filter elements or nanofiltration membrane filter elements as core components. When the filter element produces water, the booster pump connected to the raw water end of the filter element starts to provide working pressure to the filter element. At this time, after the raw water is purified by the filter element, the resulting clean water is output from the water production end, and the concentrated water flows out from the concentrated water end. When the user stops the filter element from producing water through electronic control operation, even if the booster pump stops operating immediately, due to the residual pressure in the filter element, the concentrated water will continue to flow out until the pressure in the filter element is balanced. Before the pressure in the filter element is balanced, if the connection between the concentrated water end of the filter element and the concentrated water tank is disconnected, concentrated water leakage and other phenomena will occur.

[0003] In order to avoid the above situation, one solution is to ensure that the concentrated water end of the filter element is connected to the concentrated water tank for a long time, for example, the concentrated water inlet is set on the chassis base, and water is injected from the chassis base to the concentrated water tank through the bottom water inlet method. However, this structure inevitably increases the water channel components in the base, increasing the risk of leakage or damage to the base. Summary of the invention

[0004] The purpose of the present invention is to provide a water purification device with a simple structure and an upper concentrated water tank water inlet, so as to avoid setting the concentrated water tank water inlet end in the chassis base and reduce the water path components in the chassis base. At the same time, through the structural improvement of the water tank cover, it is ensured that when there is residual pressure in the filter element and concentrated water flows out, the concentrated water will not leak out.

[0005] In order to achieve the above-mentioned purpose, the idea of ​​the present invention is to set the water inlet end of the concentrated water tank on the water tank cover of the concentrated water tank, so as to reduce the water channel components in the chassis base; on the other hand, a cavity for temporarily storing concentrated water is set in the water tank cover of the concentrated water tank. When the water tank cover is opened, the outflowing concentrated water can be temporarily stored in the cavity and then flow into the concentrated water tank when the water tank cover is closed next time.

[0006] Based on the above ideas, the present invention provides a water purification device with a concentrated water tank inlet placed on top, the water purification device comprising a chassis 101, a chassis cover 102 installed on the upper part of the chassis 101, a detachable water tank 103 and a water tank cover 104, the detachable water tank 103 is divided into a raw water tank 106 and a concentrated water tank 105, a water purification filter element is installed in the chassis 101, the water purification filter element has a raw water end, a water production end and a concentrated water end, wherein an air avoidance groove 15 is constructed on the upper part of the chassis cover 102, and a water pipe reserved hole 13 is provided in the middle of the bottom of the air avoidance groove 15;

[0007] The water tank cover 104 is composed of a water tank upper cover 2 and an inner cover 3, and is located on the upper part of the detachable water tank 103; the water tank cover 104 has a concentrated water temporary storage chamber 28, and a return hole 26 is arranged at the lower end of the concentrated water temporary storage chamber 28, and the return hole 26 is connected to the concentrated water hose 25 through the end 21; one side of the water tank cover 104 is hinged to the air avoidance groove 15, and the concentrated water hose 25 passes through the water pipe reserved hole 13 and is connected to the concentrated water end of the water purification filter element; a drainage hole 32 and an air inlet 33 are arranged on the lower surface of the water tank cover 104; the drainage hole 32 and the air inlet 33 are located away from the return hole 26;

[0008] When the water tank cover 104 is in the closed state, the drain hole 32 is located above the concentrated water tank 105 .

[0009] In the present invention, the terms "proximal end" and "distal end" are used to describe the relative positions of components. Generally, the position upstream of the waterway system is called the proximal end, while the position downstream of the waterway system is called the distal end. For example, for the water tank cover 104, the proximal end refers to a section facing the air escape groove 15, and the opposite end is the distal end.

[0010] According to a preferred embodiment, a circle of protrusions 24 is provided on the lower surface of the water tank upper cover 2, and a circle of coordination grooves 31 matching the protrusions 24 is provided on the upper surface of the inner cover 3. When the protrusions 24 cooperate with the coordination grooves 31, a concentrated water temporary storage chamber 28 is formed, and a reflux hole 26 is provided on the protrusions 24.

[0011] According to another preferred embodiment, one side of the air-avoiding groove 15 is processed into a U-shaped groove 12; one side of the inner cover 3 is processed into a U-shaped convex edge 36, and the U-shaped convex edge 36 matches the U-shaped groove 12. When the water tank cover 104 is closed, the U-shaped convex edge 36 is in a matching state with the U-shaped groove 12. When the water tank cover 104 is opened, the proximal end of the water tank cover 104 is in a matching state with the air-avoiding groove 15, ensuring that the water tank cover 104 stands up and is fixed by the air-avoiding groove 15.

[0012] In order to ensure that the water tank cover 104 is in a stable position when standing up, a pair of raised limiting ribs 14 are provided on one side of the air avoidance groove 15 .

[0013] Preferably, the convex edge 24 is formed into a rectangular or circular shape on the inner side of the water tank upper cover 2, that is, the horizontal cross-section of the concentrated water temporary storage chamber is rectangular or circular.

[0014] In the present invention, the water system in the chassis adopts a conventional water system structure, for example, including a booster pump, a water purification filter element, a concentrated water proportioner, etc. connected in sequence, wherein the water production end of the water purification filter element is connected to a water purification kettle placed on one side of the chassis, and the concentrated water end of the filter element is connected to a concentrated water hose 25, and a raw water outlet end 108 is provided on the base 107 of the chassis 101, and the raw water outlet ends are respectively connected to the raw water tank 106 and the raw water end of the water purification filter element.

[0015] When in use, ensure that the water tank cover 104 is in the closed state. The water purification equipment is started by the electronic control device, and the raw water in the raw water tank flows into the raw water end of the filter element through the raw water outlet 108 on the chassis base 107 via the booster pump, and the filter element produced water flows into the water purification kettle through the pipeline, while the filter element concentrated water enters the concentrated water temporary storage chamber 28 through the concentrated water hose and then enters the concentrated water tank 105 through the drainage hole 32.

[0016] When water production stops, there is still residual pressure in the filter element, and the concentrated water continues to be discharged. At this time, if the user opens the water tank cover 104, the water tank cover cooperates with the air avoidance groove 15 to be erected and limited by the limiting rib 14 to be in a basically vertical state. At this time, the position of the drainage hole 32 is higher than the reflux hole 26. The concentrated water produced under the residual pressure of the filter element enters the concentrated water temporary storage chamber 28 and is temporarily stored in the chamber without leaking. When the user covers the water tank cover 104, the drainage hole 32 is at the same level as the reflux hole 26 again, and the concentrated water in the chamber naturally drips into the concentrated water tank.

[0017] The water purification device of the present invention has a simple structure, and the chassis base has only a raw water outlet but no concentrated water port, which effectively simplifies the internal structure of the base. At the same time, through the structural improvement of the water tank cover, it is achieved that when there is residual pressure in the filter element and concentrated water flows out, the concentrated water is prevented from leaking out.

[0029] The following examples are used to explain the technical solutions of the present invention in a non-limiting manner.

[0030] Example 1

[0031] like Figure 1-2 The water purification device shown includes a chassis 101, a chassis cover 102 installed on the upper part of the chassis 101, a detachable water tank 103 and a water tank cover 104. A water system is installed in the chassis 101, including a connected booster pump, a water purification filter element, a concentrated water regulator, etc.

[0032] The detachable water tank 103 is placed on the chassis base 107. Figure 10-11 The detachable water tank 103 is divided into a raw water tank 106 and a concentrated water tank 105. The water outlet of the raw water tank 106 is connected to a raw water outlet 108 provided on the base 107.

[0033] Connected to the raw water outlet 108 is a water system arranged in the chassis 101. The water system of the water purification equipment belongs to the prior art, and usually includes a connected booster pump, a water purification filter element and a concentrated water regulator, wherein the water purification filter element has a raw water end, a water production end and a concentrated water end.

[0034] In order to achieve the purpose of placing the water inlet of the concentrated water tank upward, on the one hand, an air avoidance groove 15 is constructed on the upper part of the chassis cover 102, and a water pipe reserved hole 13 is provided in the middle of the bottom of the air avoidance groove 15; the air avoidance groove is used to place the water tank cover 104 in an upright state. One side of the air avoidance groove 15 is processed into a U-shaped groove 12; one side of the inner cover 3 is processed into a U-shaped flange 36, and the U-shaped flange 36 matches the U-shaped groove 12. When the water tank cover 104 is closed, the U-shaped flange 36 is in a mating state with the U-shaped groove 12. When the water tank cover 104 is opened, the proximal end of the water tank cover 104 is in a mating state with the air avoidance groove 15, ensuring that the water tank cover 104 is erected and fixed by the air avoidance groove 15, such as Figure 3-5 shown.

[0035] In order to ensure that the water tank cover 104 is in a stable position when standing up, a pair of raised limiting ribs 14 are provided on one side of the air avoidance groove 15 .

[0036] The water tank cover 104 is composed of a water tank upper cover 2 and an inner cover 3, and is located on the upper part of the detachable water tank 103. Figure 6-9As shown. A concentrated water temporary storage chamber 28 is constructed in the water tank cover 104 by the cooperation of the water tank upper cover 2 and the inner cover 3. A circle of convex edges 24 are arranged on the lower surface of the water tank upper cover 2, and a circle of matching grooves 31 matching the convex edges 24 are arranged on the upper surface of the inner cover 3. When the convex edges 24 and the matching grooves 31 are matched, a concentrated water temporary storage chamber 28 is formed. The reflux hole 26 is arranged on the convex edges 24, and the reflux hole 26 is connected to the concentrated water hose 25 through the end 21; one side of the water tank cover 104 is hinged to the air avoidance groove 15, and the concentrated water hose 25 passes through the water pipe reserved hole 13 and is connected to the concentrated water end of the water purification filter element; a drainage hole 32 and an air inlet 33 are arranged on the lower surface of the water tank cover 104; the drainage hole 32 and the air inlet 33 are located away from the reflux hole 26.

[0037] Therefore, when the water tank cover 104 is in the closed state, the drain hole 32 is located above the concentrated water tank 105. Figure 2 shown.

[0038] When in use, ensure that the water tank cover 104 is in the closed state. The water purification equipment is started by the electronic control device, and the raw water in the raw water tank flows into the raw water end of the filter element through the raw water outlet 108 on the chassis base 107 via the booster pump, and the filter element produced water flows into the water purification kettle through the pipeline, while the filter element concentrated water enters the concentrated water temporary storage chamber 28 through the concentrated water hose and then enters the concentrated water tank 105 through the drainage hole 32.

[0039] When water production stops, there is still residual pressure in the filter element, and the concentrated water continues to be discharged. At this time, if the user opens the water tank cover 104, the water tank cover cooperates with the air avoidance groove 15 to be erected and limited by the limiting rib 14 to be in a basically vertical state. At this time, the position of the drainage hole 32 is higher than the reflux hole 26. The concentrated water produced under the residual pressure of the filter element enters the concentrated water temporary storage chamber 28 and is temporarily stored in the chamber without leaking. When the user covers the water tank cover 104, the drainage hole 32 is at the same level as the reflux hole 26 again, and the concentrated water in the chamber naturally drips into the concentrated water tank.

[0040] The water purification device of the present invention has a simple structure, and the chassis base has only a raw water outlet but no concentrated water port, which effectively simplifies the internal structure of the base. At the same time, through the structural improvement of the water tank cover, it is achieved that when there is residual pressure in the filter element and concentrated water flows out, the concentrated water is prevented from leaking out.
