Description

Technical Field

[0001] The utility model relates to a water channel structure of an all-in-one water purifier. Background Art

[0002] A water purifier is a new type of water purification equipment that integrates water purification, drinking water, and heating functions. It can be directly connected to municipal water for use. The filtered water can be directly drunk, and users can choose whether to heat it. Therefore, water purifiers have gradually become popular. The water flow rate of the water purifier will become larger and larger, but when heating, it is necessary to match the heating power to control the water flow input into the heating tube to achieve the purpose of precise temperature control. Therefore, at this stage, water purifiers on the market are usually equipped with water storage devices to provide stable water supply to the heating unit. However, the installation of a water storage device will undoubtedly cause water storage. The stored water is not as fresh as the freshly filtered water. In addition, it will increase production costs and occupy the internal space of the water purifier.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes a water channel structure of an all-in-one water purifier, which does not require a water storage device and has the advantages of making fresh drinks and saving costs.

[0008] In one or more embodiments, the water channel structure also includes a bubble water module, which includes a cold water tank, a bubble water tank, a mixed water outlet and a carbon dioxide gas tank. The cold water tank is connected to the output end of the water purification module, the cold water tank and the carbon dioxide gas tank are both connected to the bubble water tank, and the cold water tank and the bubble water tank are respectively connected to the mixed water outlet.

[0009] In one or more embodiments, the cold water tank is connected to a circulating water circuit, the output end and the input end of the circulating water circuit are both connected to the cold water tank, and the circulating water circuit is connected to a circulating pump.

[0010] In one or more embodiments, the cold water tank is connected to the bubble water tank through a cold water pipe, and the cold water pipe is connected to a self-priming pump and a second one-way valve.

[0011] In one or more embodiments, the carbon dioxide gas tank is connected to the bubble water tank via a carbon dioxide pipeline, and the carbon dioxide pipeline is connected to a pressure reducing valve, a pressure switch and a third one-way valve.

[0012] Compared with the prior art, the present solution has the following beneficial effects: the water purification module in the water channel structure is provided with a return water channel, which can circulate the remaining purified water other than the water supplied to the hot water module to the water purification module, thereby eliminating the need to set up a pressure tank to buffer the surplus purified water, and ensuring that each time the water supplied to the hot water module is directly supplied after being purified by the water purification module. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic diagram of the waterway structure of an embodiment of the utility model. DETAILED DESCRIPTION

[0014] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0015] Please see attached Figure 1 The utility model provides a water channel structure of a water purifier and a drinking machine, which includes a water purification module A, a hot water module B and a return water channel 1. The return water channel connects the input end and the output end of the water purification module A. The return water channel 1 is provided with a first valve body 2 and a first non-return valve 3. The return water channel 1 is located between the first valve body and the first non-return valve and is connected with a hot water channel 4. The hot water channel is connected to the input end of the hot water module B. The hot water module includes a flow meter 5, a heat pipe 6 and a hot water outlet 7 which are sequentially connected. After the water purification module makes water, a part of the water is transported to the hot water module for heating and then outputs hot water, and the other part is transported back to the water purification module through the return water channel. Therefore, there is no need to set a pressure tank to reserve the purified water prepared by the water purification module, thereby saving costs and reducing the internal space occupied by the drinking machine.

[0016] The hot water module also includes a zero-pressure valve 8, and the zero-pressure valve, flow meter, instant heater and hot water outlet are connected in sequence. The instant heater can be a thick-film instant heater, which has the advantage of quickly heating and outputting hot water.

[0017] The water purification module A comprises a PP filter element 9, a first C filter element 10, an RO filter element 11 and a second C filter element 12 which are connected in sequence. A booster pump 13 is arranged between the first C filter element and the RO filter element. The types of the filter elements are specifically allocated and arranged according to the type of the water purifier.

[0018] The water channel structure also includes a bubble water module C, which includes a cold water tank 14, a bubble water tank 15, a mixed water outlet 16 and a carbon dioxide gas tank 26. The cold water tank is connected to the output end of the water purification module A, and the cold water tank and the carbon dioxide gas tank are both connected to the bubble water tank. The cold water tank and the bubble water tank are respectively connected to the mixed water outlet 16. Users can choose to output bubble water or cold water for drinking as needed.

[0019] The cold water tank 14 is connected to a circulating water circuit 17, the output end and the input end of the circulating water circuit are both connected to the cold water tank, and a circulating pump 18 is connected to the circulating water circuit. The cold water tank specifically protects the box body and the refrigeration module. The refrigeration module can be a semiconductor refrigeration or a refrigeration system composed of a compressor, a throttle, an evaporator and a condenser for refrigeration. The circulating water circuit can circulate the water in the cold water tank to ensure that the water temperature tends to be consistent.

[0020] The cold water tank 14 is connected to the bubble water tank 15 via a cold water pipe 19, to which a self-priming pump 20 and a second one-way valve 21 are connected to prevent the water in the bubble water tank from flowing back into the cold water tank.

[0021] The carbon dioxide tank 26 is connected to the bubble water tank 15 via a carbon dioxide pipeline 22, to which a pressure reducing valve 23, a pressure switch 24 and a third one-way valve 25 are connected. The pressure reducing valve can prevent excessive pressure of carbon dioxide input into the bubble water tank.
