Description

Technical Field

[0001] The utility model relates to kitchen appliances, in particular to a water purifier. Background Art

[0002] In families, offices and schools, pipeline machines are used to provide drinking water. Pipeline machines usually cooperate with water purifiers. A water tank is usually arranged in the pipeline machine, and then the water purified by the water purifier is stored in the water tank. According to the required drinking water temperature, the water in the water tank is directly supplied for drinking. Or the heating device in the pipeline machine is used to heat the water stored in the water tank, so as to provide hot water that can be directly drunk. For example, in the Chinese utility model patent "Water storage device and water purifying and drinking device" with the authorization announcement number CN211609274U (application number 202020021740.4), a water tank is arranged in the disclosed water purifying and drinking device to store the water purified by the purifier. This structure is more suitable for environments where the water purifying and drinking device is frequently used, so as to ensure that the water in the water tank is updated frequently. For the use environment with a low usage frequency of the water purifying and drinking device, the water in the water tank stands still for a long time, which is easy to breed bacteria and cannot meet the demand for fresh purified water.

[0003] In the under-counter instant hot water dispenser in CN217537177U, there is no need to set a water tank to store the water treated by the water purifier. Instead, through the setting of the raw water pipeline and the purified water pipeline in the pipeline machine, when the user receives water, the raw water can be directly conveyed to the water purifier through the raw water pipeline, and the water purifier can purify the raw water in real time and then output it into the purified water pipeline in the pipeline machine for use. When the under-counter instant hot water dispenser is in use, it outputs fresh purified water in real time, avoiding the problem of bacteria breeding in the water when the use time interval is long, and ensuring the water use safety at any time.

[0004] However, the instant hot water dispenser of this kind heats only purified water and cannot heat tap water. If a new pipeline is added to directly introduce tap water for heating, there will be a problem of a large amount of scale generated in the pipeline during the process of heating tap water. Another existing method is that scale has formed on the heating body when heating the raw water, and then a cleaning solution is used to wash the scale body. After the cleaning solution reacts with the scale body, the scale is washed away. This method requires a large amount of cleaning solution, is troublesome to clean, the scale body is not easy to remove, and scale formation cannot be avoided. Summary of the Utility Model

Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0029] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, terms such as "installed", "provided with", "sheathed / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be directly connected or indirectly connected through an intermediate medium. It can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] Reference Figures 1-6 , the present utility model further provides a water purification assembly, including: a water purifier 1, a water outlet faucet 2, an instant heating anti-scaling control box 4, and a four-way valve 6 connected to a corner valve 5.

[0031] The instant heating anti-scaling control box 4 in this embodiment has a first raw water inlet end 41, a pure water inlet end 42, and a hot water outlet end 43. The water purifier 1 has a second raw water inlet end 11 and a pure water outlet end 12. The water outlet faucet 2 has a third raw water inlet end 21 and a hot water inlet end 22.

[0032] Among them, the first raw water inlet end 41, the second raw water inlet end 11, and the third raw water inlet end 21 are respectively connected to three water outlet ports on the four-way valve 6. The pure water inlet end 42 of the instant heating anti-scaling control box 4 is connected to the pure water outlet end 12 of the water purifier 1. The hot water outlet end 43 of the instant heating anti-scaling control box 4 is connected to the hot water inlet end 22 of the water outlet faucet 2. In this way, the water outlet faucet 2 forms a first water flow channel and a second water flow channel. The first water flow channel communicates with the water outlet water path of the instant heating anti-scaling control box 4, and the second water flow channel communicates with the municipal water inlet. In this way, the water outlet faucet 2 can discharge the raw water that has not been heated, that is, tap water. It can also discharge the heated water. And since the instant heating anti-scaling control box 4 can directly introduce raw water or the purified pure water from the water purifier 1, the water outlet faucet 2 can also choose to discharge the heated raw water or pure water.

[0033] Since the instant heating anti-scaling control box 4 can directly receive raw water, the raw water will inevitably carry calcium and magnesium ions, carbonate ions, and hydroxide ions, and scale will be generated during the heating process of the instant heating component. To avoid this problem, in this embodiment, the instant heating anti-scaling control box 4 includes: a box body 44, an instant heating component 45 placed inside the box body 44, a control circuit board 46, an anti-scaling flushing water circuit 47, and a raw water inlet water circuit 48;

[0034] The raw water inlet water circuit 48 is connected to the first raw water inlet end 41 and the inlet end of the instant heating component 45, and the anti-scaling flushing water circuit 47 is connected to the pure water inlet end 42 and the inlet end of the instant heating component 45; the hot water outlet end 43 of the instant heating component 45 is respectively connected to the waste water circuit 49 and the outlet water circuit 40; the waste water circuit 49 and the outlet water circuit 40 are respectively provided with a first switch valve 491 and a second switch valve 401 for controlling the opening and closing of the waste water circuit 49 and the outlet water circuit 40; the signal output end of the control circuit board 46 is connected to the first switch valve 491 and the second switch valve 401. In this way, the control circuit board 46 can control the first switch valve 491 or the second switch valve 401 to open. And the anti-scaling flushing water circuit 47 and the raw water inlet water circuit 48 are respectively provided with a third switch valve 471 and a fourth switch valve 481 for controlling the opening and closing of the anti-scaling flushing water circuit 47 and the raw water inlet water circuit 48; and the signal output end of the control circuit board 46 is also connected to the third switch valve 471 and the fourth switch valve 481.

[0035] During use, if only normal temperature tap water is to be output, then as long as the mechanical handle on the water outlet faucet 2 is opened, water can be directly taken from the angle valve 5 to achieve the output of normal temperature tap water.

[0036] If heated tap water is to be output, then the fourth switch valve 481 and the second switch valve 401 need to be opened, and then raw water can flow into the instant heating component 45 and flow out from the water outlet faucet 2 after heating. And after the hot water is turned off, the program automatically activates the function of purifying water to flush and prevent scaling: close the fourth switch valve and the second switch valve 401, open the third switch valve 471 and the first switch valve 491, so that the pure water flowing out of the water purifier 1 passes through the anti-scaling flushing water circuit 47 and flows into the instant heating component 45. After the residual calcium and magnesium ions, carbonate ions, and hydroxide ions in the instant heating component 45 are washed away by the pure water, they flow out from the waste water circuit 49 together with the pure water. This ensures that there are no residues of calcium and magnesium ions, carbonate ions, and hydroxide ions in the instant heating component 45, thus avoiding the generation of scale.

[0037] If heated pure water is to be output, then the third switch valve 471 and the second switch valve 401 can be opened. Let the pure water flowing out of the water purifier 1 pass through the anti-scaling flushing water circuit 47 and flow into the instant heating component 45 and then flow out from the water outlet faucet 2 after heating.

[0038] In this embodiment, a constant flow valve is connected between the fourth switching valve 481 and the municipal water inlet to ensure a constant water flow and controllable temperature. Moreover, the instant heating assembly 45 includes a thick film heating element 451 and a temperature controller 452, and the signal output end of the control circuit board 46 is also connected to the temperature controller 452. The thick film heating element 451 is a mature instant heating method in the prior art, and no improvement has been made to it in this application, so the thick film heating element 451 will not be described in detail. The function of the temperature controller 452 is to receive the instruction of the control circuit board 46, detect the surface temperature of the thick film heating element 451, compare it with the set threshold value, and immediately switch off the power once it is higher than the set threshold value to prevent the temperature of the thick film heating element 451 from being too high.

[0039] Since the instant anti-scaling control box 4 is an independent component outside the water purifier 1, the instant heating control box needs to be fixedly installed. For this purpose, this embodiment further includes a mounting member for detachably fixing the box body 44 to the wall surface, which can be the cabinet body of the cabinet, the kitchen wall surface, or the outer shell of the water purifier 1.

[0040] There are many types of mounting members to choose from, such as the widely used adhesive tape in the prior art. The mounting member selected in this embodiment includes a connecting member detachably arranged on the wall surface and a connecting and mating member arranged on the box body. Specifically, the connecting member is a dovetail protrusion, and the connecting and mating member is a dovetail groove. The connecting member can be adhered to the outer shell of the water purifier 1 with adhesive, or can also be fixed to the cabinet body of the cabinet with bolts.

[0041] The above is only a preferred specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model who makes non-substantive modifications to the present utility model using this concept shall fall within the scope of infringement of the protection of the present utility model.
