Detailed implementation mode

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0032] Embodiment, please refer to Figures 1-3 , this application provides a low-power large-flow hot water module, including a water path distributor 3A, a metering suction and pressure valve 4A, a water inlet solenoid valve 5A, a water pump 1A, a flowmeter 2A, a water path shunt valve 8A and a heating element 12A. The water path shunt valve includes a water inlet 2-1, a first water outlet 2-2, a second water outlet 2-3 and a third water outlet 2-4; the metering suction and pressure valve, the water pump, the flowmeter and the water inlet are connected in sequence, and the heating element is arranged in the water tank 7A; a heat exchange tube 6A and a connecting tube 9A are fixed in the water tank. Among them, the heat exchange tube is preferably a stainless steel coiled tube, and the connecting tube is preferably a U-shaped tube. One end of the heat exchange tube is communicated with the third water outlet, and the other end of the heat exchange tube is communicated with the second water outlet; one end of the connecting tube is communicated with the first water outlet, and the other end is communicated with the third water outlet; the water path distributor has a clean water inlet 3-1A, a mixed water outlet 3-2A, a raw water inlet 3-3A and a clean water outlet 3-4A. The raw water inlet is communicated with raw water, and the clean water outlet is communicated with the water inlet of the metering suction and pressure valve; one end of the solenoid valve is communicated with the clean water inlet, and the other end is communicated with the water inlet. In this embodiment, a bypass tube 3-5A communicated with the clean water inlet can be arranged on the water path shunt valve. Of course, a three-way can also be directly used to connect the solenoid valve, the water inlet and the clean water inlet.

[0033] In the above embodiments, the waterway shunt valve can also be called a water flow shunt valve, and the waterway distributor can also be called a water flow distributor. The waterway shunt valve and the waterway distributor can use existing structures. When in use, the third water outlet is connected to the faucet through the secondary heating module. Of course, it can also be directly connected to the faucet with a secondary heating module. The mixed water outlet is connected to the raw water inlet pipeline of the reverse osmosis water purifier (hereinafter referred to as the RO machine), and the purified water inlet is connected to the purified water outlet pipeline of the RO machine. The water tank is filled with liquid, and generally non-drinking water can be filled. The working principle of this hot water module is as follows:

[0034] I. When the water pump is working:

[0035] Control the water inlet and the third water outlet of the waterway shunt valve to be connected. The purified water passes through the metering suction and pressure valve, the water pump and the flow meter, enters the waterway shunt valve, and then is supplied through the third water outlet and the faucet:

[0036] When a large flow of high-temperature hot water is required, control the water inlet and the second water outlet of the waterway shunt valve to be connected: The normal-temperature purified water enters the heat exchange tube from the drinking water through the second water outlet, exchanges heat energy with the high-temperature liquid in the water tank. At this time, the water is heated to a certain temperature, and after being output from the heat exchange tube, it is further heated by the secondary heating module to obtain a large flow of fresh direct drinking boiled water;

[0037] When using a large flow of low-temperature hot water, control the water inlet and the first water outlet of the waterway shunt valve to be connected. The normal-temperature purified water is output through the connecting pipe and then further heated by the secondary heating module to obtain a large flow of low-temperature hot water;

[0038] II. When using a large flow of normal-temperature purified water, the solenoid valve is opened and the secondary heating module does not work. The normal-temperature water is output through the faucet.

[0039] For convenient water replenishment, a water replenishing pipe 10A is provided on the water tank. For convenient discharge of the gas in the water tank, an exhaust pipe 11A is provided on the water tank. Both the water replenishing pipe and the exhaust pipe are connected to the inside of the water tank. Among them, the water replenishing pipe and the exhaust pipe are preferably on the top surface of the water tank.

[0040] During production, a liquid level switch can also be provided on the water tank to conveniently control the water level in the water tank, so that the stainless steel coil is immersed in the liquid, facilitating the relatively uniform heat exchange between the purified water in the stainless steel coil and the liquid. The heating element can use existing heating elements such as electric heating tubes, and a thermostat connected to the heating element can also be provided on the water tank to control the temperature of the liquid in the water tank. This is well known to those skilled in the art and will not be elaborated here.

[0041] The above waterway shunt valve is preferably a micro-controlled flow waterway shunt valve. The following is a specific structure that can be a micro-controlled flow water valve: Please refer to Figures 3-11, the differentiable flow control waterway shunt valve includes an upper cover 1 and a valve body 2.

The second diversion groove is an arc-shaped groove and is concentric with the inlet hole. The width of the second diversion groove gradually decreases from one end close to the second outlet hole to the other end; a moving ceramic 4 is provided inside the valve body. The moving ceramic abuts against the fixed ceramic from above. A strip-shaped groove 4-1 is provided at the bottom end of the moving ceramic. One end of the strip-shaped groove is communicated with the inlet hole, and the other end is located outside the first outlet hole, the second outlet hole, and the third outlet hole or is flush with the outer sides of the first outlet hole, the second outlet hole, and the third outlet hole; a driving device for driving the moving ceramic to rotate is installed on the upper cover. Among them, the driving device can use an existing structure. In this embodiment, the driving device is a motor 7, and the motor is connected to the moving ceramic. The following is a preferred connection method between the motor and the moving ceramic: A moving ceramic gland 6 is provided inside the valve body. The moving ceramic gland abuts against the moving ceramic from above, and the upper cover abuts against the moving ceramic gland; a fixing groove 4-2 is provided on the moving ceramic, and a raised block 6-1 matching the fixing groove is provided on the moving ceramic gland. The raised block is inserted into the fixing groove; the motor is fixed on the upper cover, and the motor is key-connected to the moving ceramic gland; during manufacturing, a connection key 10 can be provided inside the upper cover. The connection key includes a connection portion 10-1 and an insertion portion 10-2. The connection portion is detachably connected to the motor. Generally, the connection portion and the motor can also use a key connection method. By providing the moving ceramic gland, the machining at the key connection position of the moving ceramic can be reduced, which is beneficial to protecting the moving ceramic.

[0042] As a preferred embodiment of a flow control water valve, the diameters of the first water outlet hole and the second water outlet hole are the same; both sides of the first diversion groove coincide at one end away from the first water outlet hole; both sides of the second diversion groove coincide at one end away from the second water outlet hole; the length of the first diversion groove is less than the length of the second diversion groove. During actual manufacturing, the diameter of the third water outlet hole can be less than or equal to the diameter of the second water outlet hole; the wider end of the second diversion groove is close to the wider end of the first diversion groove.

[0043] As an embodiment of a flow control water valve, a second water inlet hole 2-6, a fourth water outlet hole 2-7, a fifth water outlet hole 2-8, and a sixth water outlet hole 2-9 are provided on the bottom surface inside the valve body. The second water inlet hole communicates with the water inlet, the fourth water outlet hole communicates with the first water outlet, the fifth water outlet hole communicates with the second water outlet, and the sixth water outlet hole communicates with the third water outlet; the second water inlet hole is correspondingly arranged with the water inlet hole, the fourth water outlet hole is correspondingly arranged with the first water outlet hole, the fifth water outlet hole is correspondingly arranged with the second water outlet hole, and the sixth water outlet hole is correspondingly arranged with the third water outlet hole; two or three notches 3-7 are circumferentially arranged on the fixed ceramic, and limiting protrusions 2-5 matching the notches are arranged on the inner surface of the valve body corresponding to the positions of the notches; the fixed ceramic abuts against the bottom surface of the valve body; a sealing gasket 5 is arranged between the fixed ceramic and the bottom surface of the valve body, and through holes are arranged on the sealing gasket corresponding to the positions of the second water inlet hole, the fourth water outlet hole, the fifth water outlet hole, and the sixth water outlet hole. Among them, the sealing gasket is a rubber gasket or a silica gel gasket, and this structure causes water leakage between the fixed ceramic and the bottom surface of the valve body.

[0044] As an embodiment of a flow control water valve, a stepped hole 1-1 is provided on the upper cover. The diameter of the stepped hole is greater than the width of the insertion part. A first sealing ring 8 is arranged in the stepped hole. The connecting part presses the first sealing ring in the stepped hole, and the motor presses the connecting part against the upper cover. During manufacturing, the motor can be connected to the upper cover by bolts. Of course, the upper cover can also be connected to the valve body by bolts. The upper cover and the valve body can be connected separately by bolts, or the bolts can pass through the connecting part of the motor and the connecting part of the upper cover in sequence and then be connected to the valve body. This is well known to those skilled in the art and will not be elaborated here; during actual manufacturing, a keyway 6-2 is provided on the moving ceramic gland, and the insertion part passes through the stepped hole and is inserted into the keyway. Among them, the insertion part is preferably a flat key. A second sealing ring 9 is preferably arranged at the connection position between the upper cover and the valve body.

[0045] As an implementation of a flow control water valve, a positioning ring 11 is also sleeved on the connecting part, and the positioning ring is fixed on the upper cover. The positioning ring can use an existing structure. In this embodiment, the positioning ring preferably uses a positioning electronic control board to facilitate the control of the motor operation.

[0046] The principle of the above-mentioned flow control water flow shunt valve is as follows:

[0047] Water enters from the water inlet, and the motor drives the moving ceramic to rotate to switch the water outlet direction. There are three water outlet directions, namely the first water outlet, the second water outlet, and the third water outlet. When it rotates to the center of the corresponding water outlet hole, it is a maximum flow straight-through. Flow guiding grooves that gradually increase from small to large are arranged at the first water outlet hole and the second water outlet hole, which can realize the function of finely adjusting the water flow rate, making it easier to adjust the water output volume at the water outlet of the water flow shunt valve.

[0048] In the above embodiment, when the reverse osmosis water purifier is not connected, the water distribution device can be not used, and the purified water source directly enters through the suction and pressure valve, and the water flow rate is adjusted and distributed by the flow control water flow shunt valve.
