Description

Technical Field

[0001] This utility model belongs to the technical field of water purification equipment, and specifically relates to a water purification heating machine. Background Technology

[0002] A water purifier is a device installed at the water inlet of a faucet or on the main water supply pipe of a household. It removes harmful substances from tap water through filtration methods such as physical interception, chemical adsorption, or ion exchange, thereby providing cleaner, safer, and better-tasting drinking water and domestic water.

[0003] For example, Chinese Patent CN109336280A discloses an under-sink integrated water purification device, including a water circuit board. From left to right, a pre-filter, an RO membrane filter, and a post-filter are connected to the bottom center of the water circuit board via filter tube connectors. Each of the pre-filter, RO membrane filter, and post-filter has a filter cap threaded onto its bottom. Several U-shaped grooves are provided on the bottom side of the water circuit board, corresponding to the sides of the pre-filter, RO membrane filter, and post-filter. These U-shaped grooves house an inlet, a concentrate outlet, a storage tank interface, and a pure water outlet, respectively. The pre-filter, RO membrane filter, and post-filter are highly integrated with the water circuit, forming a one-piece injection-molded structure. This reduces the number of water circuit interfaces and lowers the risk of leakage.

[0004] This type of water purification equipment is installed in the cabinet under the kitchen sink. The raw water connection pipe is connected to the water inlet, and the raw water is filtered into purified water through multiple filter cartridges before being supplied to the faucet. However, this purified water is only at room temperature, meaning that this type of water purifier can only produce purified water at room temperature, which reduces the frequency of use when hot water is needed, such as in winter, making it inconvenient in actual use. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a water purification and heating machine. The technical problem to be solved by this utility model is: how to improve the ease of use of water purification equipment.

[0006] The above-mentioned technical objectives of this utility model can be achieved through the following technical solutions: A water purification and heating machine includes a frame, and a hot water tank, a regulating water tank, and a control box spaced apart on the frame. The hot water tank is equipped with a heating element, an inlet pipe, and an outlet pipe. The regulating water tank has a supply pipe, and both the supply pipe and the inlet pipe are connected to the regulating water tank. The volume of the regulating water tank changes according to the water flow in the outlet pipe. The control box is electrically connected to the hot water tank.

[0007] In the aforementioned water purifier and heater, the inlet pipe is connected to the bottom of the hot water tank, and the outlet pipe is connected to the top of the hot water tank.

[0008] In the aforementioned water purification and heating machine, the regulating water tank is mounted on the frame via a bracket. The regulating water tank includes a first shell, a second shell, and an elastic diaphragm. The first shell is connected to the second shell and holds the elastic diaphragm. The first shell has an air hole. An adjusting space is formed between the second shell and the elastic diaphragm. The second shell has a three-way connector that connects to the adjusting space. The water supply pipe and the water inlet pipe are connected to the two ports of the three-way connector.

[0009] In the aforementioned water purifier and heat generator, the port where the three-way connector connects to the water supply pipe has a tapered guide hole, and the end of the tapered guide hole is a small-diameter hole, the diameter of which is smaller than the inner diameter of the other two ports.

[0010] In the aforementioned water purification and heating machine, a switch valve is installed on the water supply pipe, which can control the on / off state of the water supply pipe.

[0011] In the aforementioned water purifier and heat generator, a temperature sensor is installed on the water supply pipe, and the temperature sensor is electrically connected to the control box.

[0012] In the aforementioned water purification and heating machine, a water distribution solenoid valve is installed on the water inlet pipe, and a branch pipe is installed on the water distribution solenoid valve. The end of the branch pipe is connected to the water outlet pipe. The water distribution solenoid valve is used to control the on / off state of the water supply pipe and the water inlet pipe and the branch pipe.

[0013] In the aforementioned water purifier and heat generator, the heating element includes a heating plate, which is disposed inside the hot water tank. A second temperature sensor is disposed on the hot water tank, and both the heating plate and the second temperature sensor are electrically connected to the control box.

[0014] In the aforementioned water purification and heating machine, a water baffle is provided on the heating plate, and the water baffle is located at the end of the water inlet pipe.

[0015] In the aforementioned water purification and heating machine, an outer shell is provided on the frame, and an inlet connector and an outlet connector are provided at intervals on the outer shell. The inlet connector is connected to the water supply pipe, and the outlet connector is connected to the outlet pipe.

[0016] In summary, the beneficial effects of this utility model compared to the prior art are as follows: This heating unit is installed below the water tank, connecting the purified water output pipe of the water purifier to the water supply pipe. This allows purified water to directly enter the hot water tank from the water supply pipe, regulating water tank, and inlet pipe. The heating element heats the water in the hot water tank, thus achieving the heat treatment of the purified water by this heating unit. After the hot water tank is full, the water supply pipe continues to supply water to the hot water tank, and the hot water in the hot water tank is squeezed out from the outlet pipe, realizing the discharge of hot purified water. When the water distribution solenoid valve connects the water supply pipe and the branch pipe, room temperature purified water can be directly discharged from the outlet pipe. This application can realize the discharge of room temperature water and hot water, improving the ease of use of the water purification equipment. Moreover, this heating unit can be used with different models of water purifiers, thus broadening its application range.

[0017] Moreover, as a water flow transfer device, the regulating water tank can absorb water pressure fluctuations in the pipeline when the water supply pipe stops supplying water, thus avoiding the risk of leakage caused by drastic water pressure fluctuations. Attached Figure Description

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] A water purification and heating machine, such as Figures 1-10 As shown, the device includes a frame 100, and a hot water tank 200, a regulating water tank 300, and a control box 400 spaced apart on the frame 100. The hot water tank 200 is equipped with a heating element 230, and has an inlet pipe 210 and an outlet pipe 220. The regulating water tank 300 has a water supply pipe 500. Both the water supply pipe 500 and the inlet pipe 210 are connected to the regulating water tank 300, and the water supply pipe 500 and the inlet pipe 210 can be connected. The volume of the regulating water tank 300 changes according to the water pressure in the outlet pipe 220. The control box 400 is electrically connected to the hot water tank 200.

[0022] Furthermore, the inlet pipe 210 is connected to the bottom of the hot water tank 200, and the outlet pipe 220 is connected to the top of the hot water tank 200; when the hot water tank 200 is full of water, the inlet pipe 210 continues to supply water, and the water in the hot water tank 200 can be squeezed out from the outlet pipe 220; when the inlet pipe 210 stops supplying water, the outlet pipe 220 stops supplying water accordingly.

[0023] like Figures 3-8As shown, the regulating water tank 300 is mounted on the frame 100 via a bracket 350. The regulating water tank 300 includes a first housing 310, a second housing 320, and an elastic diaphragm 330. The first housing 310 is connected to the second housing 320 and holds the elastic diaphragm 330. The first housing 310 has an air hole 311 that connects the space between the elastic diaphragm 330 and the first housing 310 to the outside, allowing the elastic diaphragm 330 to deform normally without being affected by the air pressure between the first housing 310 and the second housing 320. An regulating space 340 is formed between the second housing 320 and the elastic diaphragm 330. The elastic diaphragm 330 can elastically contract, thereby changing the volume of the regulating space 340. The second housing 320 has a three-way connector 360 that connects to the regulating space 340. The water supply pipe 500 and the water inlet pipe 210 are connected to the two ports of the three-way connector 360. Furthermore, the height of the upper end of the regulating water tank 300 is higher than the height of the upper end of the hot water tank 200. When a large amount of water flows into the regulating space 340 from the tee connector 360, the elastic diaphragm 330 will be expanded, making the regulating space 340 larger. Conversely, if the water pressure at the tee connector 360 decreases, the elastic diaphragm 330 will contract and return to its original position, the regulating space 340 will become smaller, and water will be forced into the tee connector 360.

[0024] like Figure 8 As shown, the port of the tee connector 360 connected to the water supply pipe 500 has a tapered guide hole 361. The end of the tapered guide hole 361 is a small diameter hole 362. The diameter of the small diameter hole 362 is smaller than the inner diameter of the other two ports to prevent water from flowing backward into the water supply pipe 500. At the same time, it can increase the flow velocity of the water in the small diameter hole 362, thereby ensuring that most of the water can enter the inlet pipe 210 at high speed.

[0025] like Figure 9 , Figure 10 As shown, a switch valve 510 is installed on the water supply pipe 500, which controls the opening and closing of the water supply pipe 500 itself. The switch valve 510 is a single-inlet, single-outlet solenoid valve, and the switch valve 510 is electrically connected to the control box 400; when the switch valve 510 is open, the water supply pipe 500 is connected to the tee connector 360; when the switch valve 510 is closed, the switch valve 510 disconnects the water supply pipe 500 from the tee connector 360.

[0026] The water supply pipe 500 is also equipped with a temperature sensor 520 that is electrically connected to the control box 400. The temperature sensor 520 is used to detect the water temperature in the water supply pipe 500 and feed it back to the control box 400.

[0027] like Figures 3-4As shown, the heating element 230 includes a heating plate 231, which is disposed inside the hot water tank 200. A temperature sensor 232 is disposed on the hot water tank 200, and both the heating plate 231 and the temperature sensor 232 are electrically connected to the control box 400. The heating plate 231 is used to heat the water in the hot water tank 200, and the temperature sensor 232 is used to detect the water temperature in the hot water tank 200 and feed it back to the control box 400. In at least one embodiment, the heating element 230 is a heating rod.

[0028] A water baffle 233 is provided on the heating plate 231, and the water baffle 233 is located at the end of the water inlet pipe 210. The water baffle 233 is used to prevent the water entering the hot water tank 200 from rushing into the upper part of the hot water tank 200, thereby ensuring the heating effect of the heating plate 231 on the water flow.

[0029] like Figures 1-3 As shown, according to some embodiments, the frame 100 is also provided with a housing 110, and the housing 110 is provided with a water inlet connector 111 and a water outlet connector 112 at intervals. The water inlet connector 111 is connected to the water supply pipe 500, and the water outlet connector 112 is connected to the water outlet pipe 220.

[0030] The hot water tank 200 is equipped with an insulation cover 240, and a sewage pipe 250 is installed at the bottom of the hot water tank 200. The sewage pipe 250 is used to drain the water in the hot water tank 200 when needed.

[0031] The control box 400 is controlled by the control board 410, which includes a control panel mounted on the housing 110 or a remote control mounted on the faucet. The control box 400 contains a PLC controller, which receives control signals from the control board 410 and controls the heating plate 231 to execute heating commands.

[0032] like Figure 9 , Figure 10As shown, in some embodiments, a water distribution solenoid valve 211 is provided on the inlet pipe 210, and a branch pipe 212 is provided on the water distribution solenoid valve 211. The end of the branch pipe 212 is connected to the outlet pipe 220. The water distribution solenoid valve 211 is used to switch the on / off state of the water supply pipe 500 and the inlet pipe 210 and the branch pipe 212. The water distribution solenoid valve 211 is a one-inlet, two-outlet type. The water distribution solenoid valve 211 controls the flow of water in the water supply pipe 500. When the water distribution solenoid valve 211 connects the three-way connector 360 to the inlet pipe 210, the water flow in this path is supplied to the hot water tank 200. When the water distribution solenoid valve 211 connects the three-way connector 360 to the branch pipe 212, the water flow in this path is directly supplied to the outlet pipe 220. This outlet water does not pass through the hot water tank 200 for heating, so the water flowing from the branch pipe 212 into the outlet pipe 220 is room temperature water. Since the hot water tank 200 is full of water, the room temperature water in the outlet pipe 220 cannot flow back into the hot water tank 200. Therefore, there is no need to install a one-way valve in the outlet pipe 220 to ensure that room temperature water is discharged from the outlet pipe 220 and the outlet connector 112.

[0033] Generally, the water distribution solenoid valve 211 controls the connection between the three-way connector 360 and one of the inlet pipe 210 or the branch pipe 212 at a time.

[0034] The working principle of this utility model is as follows: This heating unit is installed below the water tank. The pipe that outputs purified water from the water purifier is connected to the water supply pipe 500, so that purified water can be directly supplied to the water supply pipe 500. The outlet pipe 220 is connected to the faucet through a pipe.

[0035] After the switch valve 510 is opened, purified water can directly enter the three-way connector 360 and split into two paths into the regulating space 340 and the inlet pipe 210. If the water distribution solenoid valve 211 connects the three-way connector 360 to the inlet pipe 210, purified water can enter the hot water tank 200 from the three-way connector 360, thus continuously replenishing the hot water tank 200. The heating plate 231 heats the water in the hot water tank 200. After the hot water tank 200 is full, the water supply to the hot water tank 200 is maintained. The hot water in the hot water tank 200 is squeezed out from the outlet pipe 220, thus discharging hot purified water. If the water distribution solenoid valve 211 connects the three-way connector 360 to the branch pipe 212, purified water is directly discharged from the branch pipe 212, the outlet pipe 220, and the outlet connector 112, thus discharging room temperature water. This application can achieve the discharge of room temperature water and hot water.

[0036] After the switch valve 510 is closed, the water supply pipe 500 stops supplying water, and the outlet pipe 220 stops discharging hot or room temperature water. At this time, the regulating water tank 300 can act as a transfer component for water flow. At the same time, the regulating space 340 can also absorb water pressure fluctuations in the downstream pipe of the regulating water tank 300, so that the water pressure in the regulating space 340 is similar to the water pressure in the outlet pipe 220, avoiding the risk of water leakage caused by drastic fluctuations in water pressure.

[0037] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model; those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
