Description

Technical Field

[0001] This invention relates to the field of water dispenser technology, and in particular to an energy-saving adjustable water temperature water dispenser and its working method. Background Technology

[0002] A water dispenser is a device that heats or cools bottled purified water (or mineral water) for convenient drinking. Bottled water is placed on top of the machine for use with bottled water dispensers. Water dispensers can be broadly categorized into three types: hot and warm, hot and cold, and hot and cold. Hot and cold dispensers are further divided into semiconductor-cooled water dispensers and compressor-cooled water dispensers. Most existing water dispensers have hot water outlets and cold water outlets on both sides of the device. Users typically need to dispensing cold water from the cold water outlet and hot water from the hot water outlet separately, mixing the two and cooling them to a suitable temperature before drinking.

[0003] The above-mentioned water filling method requires filling the water twice, which is cumbersome and does not allow for quick drinking. Even with a mixing valve to regulate the opening of the cold and hot water pipes to ensure a proportional discharge of hot and cold water so that the mixed water reaches the desired temperature, the hot and cold water are constantly being discharged during temperature adjustment. Since the receiving container already contains a certain amount of water, this water mixes with the adjusted hot and cold water in the container, resulting in a mismatch between the set hot and cold water ratio. Consequently, the mixed water temperature does not meet the user's actual needs. Furthermore, there is a significant lag in the mixing of hot and cold water, indicating uneven mixing and a reduced drinking experience. Summary of the Invention

[0004] The purpose of this invention is to provide an energy-saving adjustable water temperature dispenser and a method for operating the energy-saving adjustable water temperature dispenser, so as to improve and solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] An energy-saving adjustable water temperature water dispenser includes a body and a water outlet, and also includes:

[0007] A water supply pipeline is installed inside the machine body, and the water supply pipeline includes a cold water pipe for transporting cold water and a hot water pipe for transporting hot water.

A track plate that cooperates with the adjusting rod is provided on the outside of the body. The track plate is provided with a movable groove, which includes an upper limit groove, a lower limit groove, and a transverse groove connecting the upper limit groove and the lower limit groove.

[0009] A water mixing mechanism is provided at the output end of the temperature control mechanism and the output end of the water mixing mechanism is connected to the water outlet. The water mixing mechanism includes a fixed plate fixed in the machine body, a mixing box rotatably connected to the fixed plate, an inlet pipe provided on the mixing box and connected to the connecting hopper, an outlet pipe provided on the mixing box and connected to the water outlet, a piston plate slidably provided in the mixing box, and a drive assembly provided on the fixed plate for driving the piston plate to move. Both the inlet pipe and the outlet pipe are provided with one-way valves.

[0010] The temperature display mechanism includes a temperature sensor installed at the water outlet and a display screen installed on the machine body.

[0011] Preferably, the temperature control mechanism includes a cold water outlet at the output end of the cold water pipe, a hot water outlet at the output end of the hot water pipe, a regulating pipe that is slidably sealed around the cold water pipe and the hot water pipe, and an opening on the outer wall of the regulating pipe. The regulating pipe can be rotated so that the opening corresponds to the position of the cold water outlet and / or the hot water outlet to achieve water output according to a set ratio.

[0012] Preferably, the cold water outlet and the hot water outlet are of the same size, the distance between the left inner wall of the cold water outlet and the right inner wall of the hot water outlet is equal to the length of the opening, and a connecting bucket is provided at the opening, which is connected to the mixing water mechanism.

[0013] Preferably, the movable seat is provided with a slider, the machine body is provided with a groove that cooperates with the slider, the movable seat is provided with an arc-shaped groove on the side away from the slider, an arc-shaped block connected to a fixed ring is slidably connected in the arc-shaped groove, and a first elastic element is provided between the arc-shaped block and the inner wall of the arc-shaped groove.

[0014] Preferably, the drive assembly includes a drive motor fixed on a fixed plate, a drive shaft connected to the output end of the drive motor, a connecting plate disposed at the end of the drive shaft away from the drive motor, and a swing rod disposed at the end of the connecting plate away from the drive shaft. The end of the swing rod away from the connecting plate passes through the mixing chamber and is connected to the piston plate.

[0015] Preferably, the energy-saving adjustable water temperature dispenser further includes a heat exchange mechanism, which includes two independently operating heating boxes, a water supply pipe disposed at the output end of the heating box, a connecting pipe disposed between the water supply pipe and the hot water pipe, a heating component disposed on the outer wall of the heating box, a hot water tank disposed on the outer wall of the heating box, and a heat exchanger disposed between the two hot water tanks. The input end of the heat exchanger is connected to the inner cavity of the hot water tank through an output pipe, and the output end is connected to the water supply pipe through a return pipe.

[0016] Preferably, the machine body is provided with temperature change arrows on both sides of the track plate, and a temperature scale is provided between the two temperature change arrows. The track plate is also provided with a flat groove, and a pressure plate is elastically provided in the flat groove to abut against the adjustment rod. The track plate is also provided with a control switch that abuts against the pressure plate. The control switch is electrically connected to the drive motor.

[0017] This invention also provides a method for operating an energy-saving adjustable water temperature dispenser, comprising the following steps:

[0018] S1: Users can control the temperature control mechanism to adjust the water output ratio of cold water pipes and hot water pipes according to their own water temperature requirements.

[0019] S2: By moving the adjusting rod, the adjusting rod drives the adjusting pipe to rotate outside the cold water pipe and hot water pipe through the fixing ring. After the adjusting rod is placed in the horizontal groove from the upper limit groove, the adjusting rod is pushed horizontally to move laterally, so that the adjusting rod drives the adjusting pipe to move horizontally on the water supply pipe through the fixing ring, so that the position of the opening relative to the water outlet is adjusted laterally. Then, the adjusting rod is pressed vertically down, so that the adjusting rod moves into the lower limit groove, so that the opening of the adjusting pipe matches the cold water outlet and the hot water outlet. Cold water and hot water flow out from the corresponding openings respectively. The outflowing cold water and hot water enter the inlet pipe through the connecting hopper and enter the mixing tank.

[0020] S3: When the adjusting rod moves to the lower limit groove, it presses down on the pressure plate, causing the pressure plate to press the control switch. The control switch controls the drive motor to run. The drive motor drives the connecting plate to rotate through the drive shaft. When the connecting plate rotates, it drives the swing rod to move through the connecting rod, causing the swing rod to drive the piston plate to move up and down reciprocally in the mixing box.

[0021] S4: When the piston plate moves up and down along the inner cavity of the mixing chamber, it can mix the cold and hot water entering the mixing chamber;

[0022] S5: The hot and cold water that are evenly mixed in the mixing tank is discharged to the outlet through the outlet pipe. The temperature sensor installed in the outlet can detect the temperature of the flowing water in real time, and the display screen can display the temperature detected by the temperature sensor.

[0023] Beneficial effects: Compared with the prior art, the significant effects of the present invention are as follows:

[0024] 1. In this invention, by moving the adjusting rod, the adjusting rod drives the adjusting tube to rotate outside the water supply pipe via the fixing ring. After the adjusting rod is placed in the horizontal groove from the upper limit groove, it is pushed horizontally to move laterally, causing the adjusting rod to drive the adjusting tube to move horizontally on the water supply pipe via the fixing ring. This adjusts the position of the opening relative to the water outlet laterally. Then, the adjusting rod is pressed vertically down, moving it into the lower limit groove, so that the opening of the adjusting tube matches the cold water outlet and the hot water outlet. Cold water and hot water flow out from their corresponding openings in a proportional manner. The outflowing cold water and hot water enter the inlet pipe through the connecting hopper to mix. This avoids the water dispenser still dispensing water during water temperature adjustment, which would cause the ratio of hot water to cold water in the receiving container to not match the actual ratio of cold water to hot water after water temperature adjustment, resulting in uneven water temperature. This ensures that the mixed water temperature meets the user's requirements.

[0025] 2. In this invention, by controlling the operation of the drive motor, the drive motor drives the connecting plate to rotate through the drive shaft. When the connecting plate rotates, it drives the swing rod to move through the connecting rod, so that the swing rod drives the piston plate to move up and down in the mixing box. When the swing rod moves, it drives the mixing box to swing around the pin at the connection point with the fixed plate, so that the hot and cold water entering the mixing box are quickly mixed without the user having to wait, thus improving the user's drinking water experience.

[0026] 3. In this invention, when the mixing tank swings, the rotating rod swings accordingly. The driven bevel gear on the rotating rod meshes with the bevel gear ring, causing the driven bevel gear to drive the rotating rod to rotate. When the rotating rod rotates, the driving gear on the outer side meshes with the driven gear on the rotating shaft, causing the rotating shaft to drive the stirring blades to stir the mixed water in the mixing tank, further accelerating the mixing of hot and cold water.

[0027] 4. In this invention, when the heating component heats the water in the hot water tank, it generates steam. This steam can be transported outward through the output pipe on the outer wall of the hot water tank to the heat exchanger. After the cooling water in the heat exchanger tubes exchanges heat with this steam, the heat of the steam is stored and then transported outward through the output end of the heat exchanger. Since the output end of the heat exchanger is connected to the water supply pipe through the return pipe, the cooling water in the heat exchanger tubes that has been heated by heat exchange can flow back to the heating tank through the return pipe. In this way, the initial water temperature to be heated can be increased, the heating time of the heating component can be shortened, and energy saving can be achieved. Attached Figure Description

Detailed Implementation

[0045] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0046] Example 1: Refer to Figure 1 , Figure 2 , Figure 3An energy-saving adjustable water temperature dispenser includes a body 1 and a water outlet 5, as well as a water supply pipe, a temperature adjustment mechanism, a water mixing mechanism, and a temperature display mechanism. The water supply pipe is located inside the body 1, and includes a cold water pipe 2 for transporting cold water and a hot water pipe 3 for transporting hot water. The temperature adjustment mechanism is located outside the water supply pipe and is used to adjust the water output ratio of the cold water pipe 2 and the hot water pipe 3. The water mixing mechanism is located at the output end of the temperature adjustment mechanism and is connected to the water outlet 5. The temperature display mechanism includes a temperature sensor located in the water outlet 5 and a display screen 6 located on the body 1. During use, users control the temperature regulating mechanism according to their desired water temperature. This mechanism adjusts the flow ratio between the cold water pipe 2 and the hot water pipe 3. After discharging the cold and hot water according to the specified ratio, the cold and hot water are rapidly mixed by the mixing mechanism. The mixing mechanism then discharges uniformly heated water to the outlet 5, allowing users to collect water at the desired temperature. Furthermore, a temperature sensor inside the outlet 5 monitors the temperature of the flowing water in real time, and the display screen 6 shows the temperature detected by the sensor, facilitating temperature adjustment for users. This invention enables temperature control by discharging hot and cold water in a set ratio and allows for rapid heat exchange between the hot and cold water, preventing uneven water temperature and meeting user temperature requirements, thus enhancing the user experience.

[0047] Reference Figure 4 , Figure 5As a preferred embodiment of the present invention, the temperature regulating mechanism includes a cold water outlet 201, a hot water outlet 301, a regulating pipe 403, and an opening 4031. The cold water outlet 201 is located at the output end of the cold water pipe 2, and the hot water outlet 301 is located at the output end of the hot water pipe 3. The regulating pipe 403 is slidably and sealingly disposed around the cold water pipe 2 and the hot water pipe 3. The opening 4031 is located on the outer wall of the regulating pipe 403, and a connecting hopper 9 is provided at the opening 4031. The connecting hopper 9 is connected to the mixing water mechanism. In use, the regulating pipe 403 can be rotated so that the opening 4031 corresponds to the position of the cold water outlet 201 and / or the hot water outlet 301 to achieve water output according to a set ratio. In use, the cold water pipe 2 and the hot water pipe 3 are connected but not in communication. The regulating pipe 403... Installed between the cold water pipe 2 and the hot water pipe 3, when the driving regulating pipe 403 moves, the opening 4031 can correspond to the position of the cold water outlet 201, or the position of the hot water outlet 301, or both the cold water outlet 201 and the hot water outlet 301 simultaneously. In this way, when the opening 4031 corresponds to the cold water outlet 201, cold water is dispensed; when the opening 4031 corresponds to the hot water outlet 301, hot water is dispensed; and when the opening 4031 corresponds to both the cold water outlet 201 and the hot water outlet 301, both hot and cold water can be dispensed simultaneously. Moreover, the temperature can be controlled by adjusting the ratio of the cold water outlet 201 and the hot water outlet 301 to the opening 4031.

[0048] It should be noted that the cold water outlet 201 and the hot water outlet 301 are the same size. The distance between the left inner wall of the cold water outlet 201 and the right inner wall of the hot water outlet 301 is equal to the length of the opening 4031. In this way, when the left end of the opening 4031 corresponds to the cold water outlet 201, the function of only discharging cold water can be realized; when the left end of the opening 4031 is outside the right end of the cold water outlet 201, the function of only discharging hot water can be realized; and when the opening 4031 is connected to both the cold water outlet 201 and the hot water outlet 301, the effect of discharging both cold water and hot water can be realized. In this way, the water discharged through the cold water pipe 2 and / or the hot water pipe 3 can be discharged into the connecting hopper 9 through the opening 4031 and then into the mixing water mechanism.

[0049] Reference Figure 6As a preferred technical solution of the present invention, the temperature regulating mechanism further includes a movable seat 401, a fixed ring 402, and an adjusting rod 404. The movable seat 401 is slidably disposed on the inner wall of the body 1, the fixed ring 402 is movably disposed on the movable seat 401, the adjusting rod 404 is fixedly disposed on the outer wall of the fixed ring 402, and the adjusting tube 403 is fixedly disposed on the inner wall of the fixed ring 402. In this way, by driving the adjusting rod 404, the adjusting tube 403 can be rotated or slid, thereby adjusting the position of the opening 4031 to adjust the hot and cold water output.

[0050] Furthermore, refer to Figure 7 To achieve quantitative control of the hot and cold water output, a track plate 7 is provided on the outside of the main body 1 to cooperate with the adjusting rod 404. Specifically, the track plate 7 is provided with a movable groove, which includes an upper limit groove 701 evenly spaced along the length of the opening, a lower limit groove 702 corresponding to the position of the upper limit groove 701, and a transverse groove 703 connecting the upper limit groove 701 and the lower limit groove 702. In use, the user moves the adjusting rod 404, causing the adjusting rod 404 to drive the adjusting pipe 403 to rotate outside the cold water pipe 2 and the hot water pipe 3 through the fixing ring 402. After the adjusting rod 404 is placed in the transverse groove 703 from the upper limit groove 701, the user pushes the adjusting rod 404 horizontally to move it laterally, causing the adjusting rod 404 to drive the adjusting pipe 403 to move horizontally on the water supply pipe through the fixing ring 402, so that the opening 4031 is relative to the cold water outlet 20. 1. The position of the hot water outlet 301 is adjusted horizontally, and then the adjusting rod 404 is pressed down vertically to move the adjusting rod 404 into the lower limit groove 702, so that the opening 4031 of the adjusting pipe 403 matches the cold water outlet 201 and the hot water outlet 301. Cold water and hot water flow out from the corresponding openings 4031 respectively. According to the required water temperature, the opening of the cold water outlet 201 and the hot water outlet 301 is first adjusted. Then, by using the correspondence between the cold water outlet 201 and the hot water outlet 301 and the opening 4031, the cold and hot water are discharged in a predetermined ratio to achieve the purpose of water temperature control. This can avoid the water dispenser still dispensing water when the water temperature is being adjusted, which would result in the ratio of hot water to cold water in the final water container not meeting the set required ratio. This ensures that the mixed water temperature meets the user's water temperature requirements and improves the user experience.

[0051] Specifically, when the adjusting rod 404 is placed in the leftmost limiting groove of the track plate 7, the adjusting pipe 403 blocks the hot water outlet 301 and fully opens the cold water outlet 201. At this time, only cold water flows out of the water dispenser. When the temperature adjustment mechanism is activated, the position of the adjusting pipe 403 on the delivery pipe is adjusted. That is, when the adjusting pipe 403 moves to the right, the cold water outlet 201 gradually becomes smaller and the hot water outlet 301 gradually becomes larger. The opening size of the cold water outlet 201 and the hot water outlet 301 is controlled, thereby adjusting the ratio of cold and hot water output so that the water temperature discharged by the water dispenser after mixing cold and hot water meets the user's needs. When the adjusting rod 404 moves to the rightmost limiting groove of the track plate 7, the adjusting pipe 403 blocks the cold water outlet 201 and fully opens the hot water outlet 301. At this time, only hot water flows out of the water dispenser.

[0052] It should be noted that since there are multiple movable slots and they correspond to the position of the cold water outlet 201, they can serve as a scale indication. Therefore, when the adjusting rod 404 is moved into the corresponding movable slot, the opening size of the cold water outlet 201 and the hot water outlet 301 can be adjusted.

[0053] Furthermore, in order to enable the movable seat 401 to slide along the inner wall of the machine body 1, thereby adjusting the position of the opening 4031 on the adjusting tube 403, a slider 4011 is provided on the movable seat 401. Correspondingly, a groove 101 that cooperates with the slider 4011 is provided on the machine body 1. An arc-shaped groove 8 is provided on the side of the movable seat 401 away from the slider 4011. An arc-shaped block 801 connected to the fixing ring 402 is slidably connected in the arc-shaped groove 8. A first elastic element 802 is provided between the arc-shaped block 801 and the inner wall of the arc-shaped groove 8. In use, when the adjusting rod 404 is placed in the horizontal groove 7... When the adjustment tube 403 is in position 03, the position of the adjustment tube 403 on the cold water pipe 2 and the hot water pipe 3 is adjusted by the fixing ring 402. During this process, the fixing ring 402 drives the slider 4011 to slide on the slide groove 101 through the moving seat 401, which improves the stability of the movement of the adjustment tube 403. When the fixing ring 402 rotates relative to the moving seat 401, the arc block 801 slides in the arc groove 8 and squeezes the first elastic element 802. When the adjustment rod 404 is no longer under force, the arc block 801 is reset under the push of the first elastic element 802, so that the adjustment rod 404 automatically moves to the upper limit groove 701.

[0054] Reference Figure 8 , Figure 9As a preferred embodiment of the present invention, the water mixing mechanism includes a fixed plate 10, a mixing tank 11, an inlet pipe 111, an outlet pipe 112, a piston plate 113, and a drive assembly. The fixed plate 10 is fixed inside the machine body 1. The mixing tank 11 is rotatably connected to the fixed plate 10 via a rotating shaft. The inlet pipe 111 is disposed on the mixing tank 11 and communicates with the connecting hopper 9. The outlet pipe 112 is disposed on the mixing tank 11 and communicates with the outlet section 5. The piston plate 113 is slidably disposed on the mixing tank. Inside the mixing tank 11, a drive assembly is mounted on a fixed plate 10 to drive the piston plate 113 to move. Furthermore, both the inlet pipe 111 and the outlet pipe 112 are equipped with one-way valves. In use, the hot and cold water collected through the connecting bucket 9 enters the mixing tank 11 through the inlet pipe 111. At this time, the piston plate 113 is driven to slide in the mixing tank 11 under the drive assembly, thereby agitating the hot and cold water entering the mixing tank 11 to achieve a mixing effect and avoid the lag in the mixing of hot and cold water.

[0055] Furthermore, the drive assembly includes a drive motor 12, a drive shaft 121, a connecting plate 122, and a swing rod 124. The drive motor 12 is fixedly mounted on the fixed plate 10, the drive shaft 121 is connected to the output end of the drive motor 12, the connecting plate 122 is fixedly sleeved on the end of the drive shaft 121 away from the drive motor 12, and the swing rod 124 is rotatably disposed on the end of the connecting plate 122 away from the drive shaft 121. The end of the swing rod 124 away from the connecting plate 122 passes through the mixing chamber 11 and is connected to the piston plate 113. In addition, a connecting rod 123 is provided between the swing rod 124 and the connecting plate 122, one end of which is rotatably connected to the connecting plate 122. One end is rotatably connected to the swing rod 124. In use, the drive motor 12 is controlled to run. The drive motor 12 drives the connecting plate 122 to rotate through the drive shaft 121. When the connecting plate 122 rotates, it drives the swing rod 124 to move through the connecting rod 123. This causes the swing rod 124 to drive the piston plate 113 to move up and down in the mixing tank 11. When the swing rod 124 moves, it drives the mixing tank 11 to swing around the pin at the connection with the fixed plate 10. This allows the hot and cold water entering the mixing tank 11 to be fully mixed. In addition, when the piston plate 113 moves down in the mixing tank 11, it can extract the hot and cold water in the inlet pipe 111, thus achieving complete access to the hot and cold water.

[0056] Furthermore, refer to Figure 10. Figure 11 , Figure 12To ensure thorough mixing of the hot and cold water in the mixing tank 11, a rotating rod 13 is rotatably mounted inside the mixing tank 11. A driven bevel gear 131 is mounted on the top of the rotating rod 13. A bevel gear ring 14, meshing with the driven bevel gear 131, is mounted on the fixed plate 10. A driving gear 132 is mounted on the rotating rod 13. A rotating shaft 15 is also rotatably connected inside the mixing tank 11. A driven gear 151, meshing with the driving gear 132, is mounted on the rotating shaft 15. Furthermore, a groove 152 is formed in the side wall of the rotating shaft 15 within the mixing tank 11. A stirring blade 1521 is connected to the groove 152 via a rotating shaft. A torsion spring 1522 is mounted on the rotating shaft for the stirring blade 1521 to return to its original rotation position. The stirring blade 1521... Piston plate 113 moves against each other. During use, when the mixing tank 11 swings, rotating rod 13 swings accordingly. Driven bevel gear 131 on rotating rod 13 meshes with bevel gear ring 14, causing driven bevel gear 131 to drive rotating rod 13 to rotate. When rotating rod 13 rotates, outer drive gear 132 meshes with driven gear 151 on rotating shaft 15, causing rotating shaft 15 to drive stirring blade 1521 to stir the mixed water in mixing tank 11, further accelerating the mixing of hot and cold water. By making stirring blade 1521 elastically set on rotating shaft 15, stirring blade 1521 is prevented from obstructing the reciprocating movement of piston plate 113 in mixing tank 11, ensuring the normal operation of the mixing water mechanism and realizing rapid mixing of hot and cold water in mixing tank 11.

[0057] As a preferred embodiment of the present invention, the body 1 is provided with temperature change arrows 16 on both sides of the track plate 7, and a temperature scale 161 is provided between the two temperature change arrows 16. A flat groove 704 is also provided on the track plate 7, and a pressure plate 17 is elastically disposed within the groove 704 to abut against the adjusting rod 404. A control switch 18 is also provided on the track plate 7 to abut against the pressure plate 17. The control switch 18 is electrically connected to the drive motor 12. By providing temperature rise and fall arrows on the outside of the body 1 and on both sides of the track plate 7, it is convenient for the user to correctly adjust the water temperature and clearly identify the positions of the cold water and hot water ends. Furthermore, a temperature scale 161 is provided between the two temperature change arrows 16, which allows the user to accurately control the size of the outlets of the cold water pipe 2 and the hot water pipe 3 when adjusting the position of the adjusting rod 404, thereby achieving a more precise adjustment of the final mixed water temperature. When the adjusting rod 404 moves to the lower limit groove 702, the adjusting rod 404 can press down on the pressure plate 17, causing the pressure plate 17 to press the control switch 18. The control switch 18 controls the drive motor 12 to run, thus enabling the temperature adjustment mechanism to operate. Therefore, the mixing water mechanism can quickly mix the cold and hot water discharged by the temperature adjustment mechanism, allowing the water to quickly reach the temperature required by the user and avoiding uneven heating and cooling of the water.

[0058] Example 2: Refer to Figure 13 , Figure 14 , Figure 15 Similar to Embodiment 1, except that the energy-saving adjustable water temperature dispenser further includes a heat exchange mechanism. This mechanism comprises a heating chamber 302, a water supply pipe 303, a connecting pipe 304, a heating element, a hot water tank 305, and a heat exchanger 306. There are two heating chambers 302, which operate independently. The water supply pipe 303 is located at the output end of the heating chamber 302, and the connecting pipe 304 is located between the water supply pipe 303 and the hot water pipe 305. The heating element is located on the outer wall of the heating chamber 302. Specifically, the heating element includes a heating power supply 309 and a heating tube 3010 electrically connected to the output end of the heating power supply. This heating tube can be a spiral heating tube, spirally wound around the outer wall of the heating chamber 302. The hot water tank 305 is located on the outer wall of the heating chamber 302. A heat exchanger 306 is disposed between two hot water tanks 305 to recover and utilize heat. Furthermore, the input end of the heat exchanger 306 is connected to the inner cavity of the hot water tank 305 via an output pipe 307, and the output end is connected to the water supply pipe 303 via a return pipe 308. In this invention, the hot water is stored in a heating tank 302, and is indirectly heated by a heating component disposed on the outer wall of the heating tank 302. During use, the heating tank 302 contains water to be heated, and the hot water tank 305 contains water for indirectly heating the heating tank 302. The heating component heats the water in the hot water tank 305, thereby heating the water in the heating tank 302 to the required hot water temperature, which is then supplied to the hot water pipe 303 via the water supply pipe 303.

[0059] It should be noted that the heat exchange tubes inside the heat exchanger 306 store cooling water. During use, the temperature of the cooling water is lower than that of the steam, and the cooling water can circulate along the input and output ends of the heat exchanger 306 to achieve heat exchange. Therefore, when the heating element heats the water in the hot water tank 305, it will generate steam. The steam can be transported outward through the output pipe 307 on the outer wall of the hot water tank 305 to the heat exchanger 306. After the cooling water in the heat exchange tubes of the heat exchanger 306 exchanges heat with this part of the steam, the heat of this part of the steam is stored and then transported outward through the output end of the heat exchanger 306. Since the output end of the heat exchanger 306 is connected to the water supply pipe 303 through the return pipe 308, the cooling water in the heat exchange tubes that has been heated by heat exchange can flow back to the heating box 302 through the return pipe 308. In this way, the initial water temperature to be heated can be increased, the heating time of the heating element can be shortened, and energy saving can be achieved.

[0060] This invention can effectively improve the energy efficiency of the water pump by storing and reusing the steam heat generated during the heating of the hot water tank 305. The following uses two technical solutions, Example 1 and Example 2, as examples to further illustrate the technical effect of the water pump in this embodiment in terms of energy saving.

[0061] Taking a water dispenser with a daily hot water capacity of 400 liters and a power of 6kW as an example, the performance indicators of the water pumps in Examples 1 and 2 are as follows:

[0062] Example 1 Example 2 Electricity consumption (kWh / day) 40 36 Thermal insulation efficiency (%) 30 98 Insulation power consumption (kWh / day) 28 0.72

[0063] As can be seen from the table above, the heat exchange mechanism of Example 2 has a significant improvement in energy saving compared to the traditional water pump. This is because the steam generated by the water heater can be discharged into the heat exchanger through the output pipe to heat the cooling water in the heat exchanger to realize the utilization of steam energy. After the cooling water is heated to a higher temperature, it can be transported to the water supply pipe through the return pipe and enter the heating box to mix with the water to be heated. This can increase the initial temperature of the water to be heated, thereby effectively shortening the water heating time. Therefore, it has a significant improvement in energy saving and consumption reduction.

[0064] Furthermore, this invention also discloses a method for operating an energy-saving adjustable water temperature dispenser, comprising the following steps:

[0065] S1: The user controls the temperature control mechanism according to their own water temperature needs, so that the temperature control mechanism adjusts the water output ratio of cold water pipe 2 and hot water pipe 3.

[0066] S2: By moving the adjusting rod 404, the adjusting rod 404 drives the adjusting pipe 403 to rotate outside the cold water pipe and hot water pipe through the fixing ring 402. After the adjusting rod 404 is placed in the horizontal groove 703 from the upper limit groove 701, the adjusting rod 404 is pushed horizontally to move laterally, so that the adjusting rod 404 drives the adjusting pipe 403 to move horizontally on the water supply pipe through the fixing ring 402, so that the position of the opening 4031 relative to the water outlet is adjusted laterally. Then, the adjusting rod 404 is pressed vertically down, so that the adjusting rod 404 moves into the lower limit groove 702, so that the opening 4031 of the adjusting pipe 403 matches the cold water outlet 201 and the hot water outlet 301. Cold water and hot water flow out from the corresponding openings 4031 respectively. The cold water and hot water flow out through the connecting bucket 9 into the inlet pipe 111 and into the mixing box 11.

[0067] S3: When the adjusting rod 404 moves to the lower limit groove 702, it presses down on the pressure plate 17, causing the pressure plate 17 to press the control switch 18. The control switch 18 controls the drive motor 12 to run. The drive motor 12 drives the connecting plate 122 to rotate through the drive shaft 121. When the connecting plate 122 rotates, it drives the swing rod 124 to move through the connecting rod 123, causing the swing rod 124 to drive the piston plate 113 to move up and down reciprocally in the mixing box 11.

[0068] S4: When the piston plate 113 moves up and down along the inner cavity of the mixing tank 11, it can mix the hot and cold water entering the mixing tank 11. When the mixing tank 11 swings, the rotating rod 13 swings accordingly. The driven bevel gear 131 on the rotating rod 13 meshes with the bevel gear ring 14, causing the driven bevel gear 131 to drive the rotating rod 13 to rotate. When the rotating rod 13 rotates, the outer driving gear 132 meshes with the driven gear 151 on the rotating shaft 15, causing the rotating shaft 15 to drive the stirring blade 1521 to stir the mixed water in the mixing tank 11.

[0069] S5: The hot and cold water mixed evenly in the mixing tank 11 is discharged to the water outlet 5 through the water outlet pipe 112. The temperature sensor installed in the water outlet 5 can detect the temperature of the flowing water in real time. The display screen 6 can display the temperature detected by the temperature sensor. Users can collect the water that meets the temperature requirements after mixing through the water receiving container.

[0070] As a preferred technical solution of the present invention, the working method of the energy-saving adjustable water temperature water dispenser further includes:

[0071] S5: When the heating component heats the water in the hot water tank 305, the steam generated can be sent to the heat exchanger 306 through the output pipe 307. After the cooling water in the heat exchange tube of the heat exchanger 306 exchanges heat with this part of the steam, it is sent to the water supply pipe 303 through the return pipe 308 at the output end of the heat exchanger 306, and finally enters the heating tank 302 to increase the initial water temperature of the water to be heated.

[0072] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
