Description

Technical Field

[0001] This utility model relates to the field of water supply device technology, and in particular to a water supply device. Background Technology

[0002] A water heater is a device used to produce hot water. With people's pursuit of convenience, water heaters have become one of the most commonly used household appliances today. In daily life, people often need hot water, such as for washing hands and faces. With a water heater, hot water is readily available simply by turning on the tap, eliminating the need to wait for water to boil on a stove or be transported from other hot water sources, greatly saving time.

[0003] When the heating tank in a water heater is heating, water vapor is generated inside. If the water vapor inside the heating tank cannot be discharged, water vapor will continue to be generated as the heating process continues. When the pressure exceeds the limit that the heating tank can withstand, it may cause damage to the heating tank. Furthermore, too much water vapor accumulating inside the heating tank will affect the heating efficiency, as the thermal conductivity of water vapor is much lower than that of water.

For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] See Figure 1 This application provides a water supply device, including an inlet pipe 1, a heat exchange device 2, and a heat tank 3. The heat exchange device 2 is provided with a water flow channel and a heat exchange medium channel that are isolated from each other. The inlet pipe 1 is connected to the water flow channel. The heat tank 3 is used to contain the heat exchange medium. The heat tank 3 is connected to a heat exchange power component 31 for making the heat exchange medium flow through the heat exchange medium channel. The heat tank 3 is provided with an exhaust port. The exhaust port is connected to an exhaust component 4. The exhaust component 4 is thermally connected to the inlet pipe 1.

[0030] In practical applications, the water supply device may also include a heater 5 and an outlet pipe 6. The water flow channel is connected to the inlet pipe 1 and the outlet pipe 6 respectively. The heater 5 can be set between the water flow channel and the outlet pipe 6. During normal operation, the water source enters the water flow channel from the inlet pipe 1 and is then led out to the outside from the outlet pipe 6 for user use.

[0031] The heat exchange medium contained in the heat tank 3 can be a high-temperature liquid such as hot water. The heat tank 3 is connected to the heat exchange medium channel. The heat exchange power component 31 drives the hot water (heat exchange medium) in the heat tank 3 to flow in the heat exchange medium channel. When the hot water (heat exchange medium) flows in the heat exchange medium channel, it exchanges heat with the water in the water flow channel, thereby heating the water in the water flow channel. After the temperature of the hot water (heat exchange medium) decreases, it returns to the heat tank 3 through the heat exchange medium channel for reheating, so that the hot water (heat exchange medium) circulates between the heat tank 3 and the heat exchange medium channel, ensuring that the hot water (heat exchange medium) in the heat exchange medium channel always maintains a high temperature. After the water in the water flow channel is heated by the hot water (heat exchange medium) in the heat exchange medium channel, when the water flows to the outlet pipe 6, according to the set outlet water temperature, it can be reheated by the heater 5 set between the water flow channel and the outlet pipe 6, so that it is heated again to reach the specified temperature before being discharged from the outlet pipe 6, realizing the function of the water supply device to provide hot water. The heater 5 can be a thick film heater or similar structure. Of course, in a possible implementation, the heater 5 can also be placed between the water inlet pipe 1 and the water flow channel, so that the water is first heated by the heater 5 and then heated a second time by the heat exchange medium channel.

[0032] Meanwhile, the heating tank 3 is equipped with an exhaust port to discharge water vapor inside, preventing excessive pressure and potential malfunctions. The exhaust port vents air through the exhaust component 4 to the water inlet pipe 1, transferring heat from the water vapor to the inlet pipe 1. This allows the water to absorb heat from the water vapor as it flows through the inlet pipe 1, raising its temperature before entering the water flow channel. Consequently, the heat exchange medium channel and heater 5 only need to heat the water for a shorter time to reach the set temperature, improving heating efficiency. This also allows for the use of a smaller heater 5 or a smaller heating tank 3, saving production costs. Furthermore, the water inlet pipe 1 cools and condenses the water vapor, causing it to condense into water droplets that flow back into the heating tank 3 along the exhaust component 4, replenishing the tank and compensating for the heat exchange medium consumed during the heat exchange process.

[0033] Compared to existing technologies, this application includes a heating tank 3 and an exhaust component 4. The heating tank 3 is mainly used to exchange heat with the water flow in the heat exchange device 2, thereby raising the water temperature. This reduces the time required for the heater 5 to reheat the water flow to the set temperature, achieving the effect of instant hot water. At the same time, the exhaust port of the heating tank 3 discharges to the water inlet pipe 1 through the exhaust component 4. The water flow exchanges heat with water vapor as it passes through the water inlet pipe 1, raising the water temperature. Therefore, the heating tank 3 and heater 5 only need to heat the water flow for a short time to raise it to the set temperature. This facilitates the use of water vapor in the heating tank 3 to heat the water flow, greatly improving heating efficiency. Furthermore, the immediate discharge of water vapor from the heating tank 3 ensures that the internal pressure of the heating tank 3 is maintained, preventing any impact on the normal operation of the heating tank 3.

[0034] In one embodiment, the exhaust component 4 may include a condenser and a connecting pipe, the connecting pipe being connected to an exhaust port, and the connecting pipe being thermally connected to the water inlet pipe through the condenser.

[0035] In one embodiment, the condensing device may include a heat exchange tube for containing refrigerant, and a connecting pipe for transferring heat from steam to the heat exchange tube. The hot end of the condensing device is connected to the wall of the water inlet pipe 1. In practical applications, the connecting pipe is connected to the vent and in contact with the heat exchange tube. The end of the heat exchange tube in contact with the connecting pipe is filled with refrigerant. When water vapor enters the connecting pipe, the water vapor transfers heat to the refrigerant in the heat exchange tube. The refrigerant is heated and vaporizes, diffuses to the other end of the heat exchange tube, and liquefies at the other end of the heat exchange tube, releasing a large amount of heat. The hot end of the condensing device refers to the end where the refrigerant liquefies. The hot end of the condensing device transfers the heat released by the liquefaction of the refrigerant to the water inlet pipe 1, thereby heating the water flow in the water inlet pipe 1. Using a condensing device can effectively improve the thermal energy utilization rate of water vapor and save on the cost of thermal energy use.

[0036] It should be noted that the connection between the connecting pipe and the heat exchange pipe can be achieved by bonding or wrapping.

[0037] See Figure 2 The exhaust component 4 may also include a heat pipe 41, which has a first end 411 and a second end 412 along its length. The first end 411 is connected to the exhaust port, and the second end 412 is used to connect to the hot tank 3 or the wastewater pipe.

[0038] In practical applications, one end of heat pipe 41 is connected to the exhaust port, and the other end is connected to the wastewater pipe or the hot tank 3. Heat pipe 41 can contact the water inlet pipe 1. When water vapor flows in heat pipe 41, it exchanges heat with the water flow in the water inlet pipe 1 through the contact surface. After the heat exchange, the water vapor will liquefy to form water droplets. The water droplets can be discharged outside the device through the wastewater pipe or return to the hot tank 3 to replenish the water volume of the hot tank 3 in time and maintain the normal operation of the hot tank 3.

[0039] See again Figure 2 In one embodiment, the heat pipe 41 can be attached to the outer periphery of the water inlet pipe 1. This arrangement makes it convenient to install and replace the heat pipe 41. One or more heat pipes 41 can be provided, and this application does not limit this.

[0040] See Figure 3 In one embodiment, the heat pipe 41 can be arranged around the outer periphery of the water inlet pipe 1. In this way, when the heat pipe 41 is arranged around the outer periphery of the water inlet pipe 1, heat can be transferred from all sides of the heat pipe 41 to the water inlet pipe 1. This method increases the contact area between the heat pipe 41 and the water inlet pipe 1, especially in the direction of pipe length, which can form a spiral heat conduction path, which is beneficial to the uniform distribution and transfer of heat.

[0041] See Figure 4 In one embodiment, the heat pipe 41 can be wrapped around the outer periphery of the water inlet pipe 1. This arrangement provides more comprehensive thermal contact and maximizes the contact area. Heat can be evenly transferred to the water inlet pipe 1 from all directions, avoiding situations where the contact is slightly poor in some areas.

[0042] See Figure 5 The exhaust component 4 may also include a connecting part and an exhaust part 42. The exhaust part 42 has a through hole 422 extending through both ends along its axial direction. The water inlet pipe 1 passes through the through hole 422. The exhaust part 42 has at least one vent hole 421 along its circumference, and / or, the exhaust part 42 has at least one vent hole 421 along its axial direction. The vent hole 421 communicates with the through hole 422, and the connecting part communicates with the exhaust hole and the vent hole 421 respectively.

[0043] In practical applications, the water vapor in the heating tank 3 is guided to the vent 421 through the connecting part. The vent 421 is connected to the through hole 422, and the water inlet pipe 1 is installed in the through hole 422. In this way, the water vapor is directly sprayed from the vent 421 onto the outer periphery of the water inlet pipe 1, so that the water flow inside the water inlet pipe 1 can directly absorb the heat of the water vapor. Compared with other methods, this heating method reduces the intermediate parts of heat transfer. The heat energy of the water vapor can directly act on the water inlet pipe 1, avoiding the heat loss that may occur due to transfer through other media. This allows the heat to be absorbed by the water in the water inlet pipe 1 more efficiently, improving the energy utilization efficiency.

[0044] In one embodiment, the wall of the through hole 422 is sealed to the wall of the water inlet pipe 1, thereby preventing water vapor from leaking out of the through hole 422 and preventing water vapor from contacting the outside air, ensuring that the temperature of the water vapor does not drop and preventing heat loss.

[0045] In one embodiment, the wall of the through hole 422 can be welded to the wall of the water inlet pipe 1. The welding can form a continuous and uniform weld, which can effectively prevent water vapor leakage and ensure the reliability of the seal.

[0046] In one embodiment, the venting component 4 may include a sealing ring, which abuts against the pipe wall of the water inlet pipe 1 and the hole wall of the through hole 422 respectively. The sealing ring has a certain elasticity and deformation capacity, which can compensate for the roughness and unevenness of the sealing surface to a certain extent, maintain a good sealing effect, and make it easy to remove the venting component 4 from the water inlet pipe 1, thereby improving practicality.

[0047] See again Figure 5 The exhaust section 42 includes a first part 423 and a second part 424, which are respectively covered together from opposite sides of the water inlet pipe 1. The first part 423 and the second part 424 form a through hole 422. The first part 423 and the second part 424 are detachably connected; or the first part 423 and the second part 424 are fixedly connected.

[0048] In practical applications, in order to facilitate the installation of the exhaust part 42, the exhaust part 42 can be composed of a first part 423 and a second part 424. The first part 423 and the second part 424 cover each other from opposite sides of the water inlet pipe 1, and then the first part 423 and the second part 424 are connected so that they clamp the water inlet pipe 1 from opposite sides respectively, thereby fixing the exhaust part 42 to the water inlet pipe 1.

[0049] The first part 423 and the second part 424 can be detachably connected by means of plugging or snapping, which makes it easy to disassemble and replace the exhaust part 42.

[0050] The first part 423 and the second part 424 can also be fixedly connected by welding or other means, which improves the connection stability of the first part 423 and the second part 424, thereby improving the connection stability and sealing of the exhaust part 42 and the water inlet pipe 1, and preventing water vapor from leaking between the exhaust part 42 and the water inlet pipe 1.

[0051] It should be noted that the exhaust section 42 should also be equipped with a return hole, which is connected to the hot tank 3 or the wastewater pipe, so as to allow the water droplets formed by the liquefaction of water vapor after heat conduction to flow back to the hot tank 3 or be discharged to the outside of the device.

[0052] In one embodiment, the connecting part may pass through the heat exchange device 2, and the connecting part is used to heat the water flow channel and / or the heat exchange medium channel. When water vapor enters the connecting part, the connecting part exchanges heat with the water flow channel or the heat exchange medium channel, and uses the temperature of the water vapor to heat the water flow in the heat exchange device 2, realizing multiple utilization of heat energy, greatly improving the heating efficiency of the water supply device, and enhancing the energy-saving effect of the water supply device.

[0053] In one embodiment, the first end 411 of the heat pipe 41 can also pass through the heat exchange device 2 and be connected to the exhaust port. The first end 411 is used to heat the water flow channel and / or the heat exchange medium channel. It is understood that when using the heat pipe 41, the first end 411 of the heat pipe 41 can also pass through the heat exchange device 2. After water vapor enters the heat pipe 41 through the first end 411, it exchanges heat with the water flow channel or the heat exchange medium channel through the first end 411, which can also achieve the above-mentioned function.

[0054] The hot tank 3 is connected to a heating element for heating the heat exchange medium. The heating element is located inside the hot tank 3, or the heating element is located outside the hot tank 3.

[0055] In practical applications, the heat exchange medium inside the hot tank 3 always needs to be at a high temperature. Therefore, a heating element is required to heat the heat exchange medium and ensure that the heat exchange medium is at the set temperature. The heating element can be installed inside the hot tank 3, saving the space and volume of the entire device; the heating element can also be installed on the outside, which makes installation more convenient and facilitates maintenance and replacement.

[0056] See again Figure 1 The heat exchange power component 31 includes a circulating pump 311, a first pipeline 312 and a second pipeline 313. The heat exchange medium channel has an outlet and an inlet. The first pipeline 312 is connected to the heat tank 3 and the inlet, respectively. The second pipeline 313 is connected to the heat tank 3 and the outlet, respectively. The circulating pump 311 is connected to the first pipeline 312. The circulating pump 311 is used to make the heat exchange medium flow through the heat exchange medium channel.

[0057] In practical applications, the heat exchange medium channel usually has an inlet and an outlet. The first pipeline 312 is connected to the inlet, and the circulating pump 311 pumps the hot water in the heat tank 3 from the inlet into the heat exchange medium channel. After the hot water flows in the heat exchange medium channel and exchanges heat with the water flow channel, the hot water temperature decreases. Then, it flows back to the inside of the heat tank 3 from the outlet through the second pipeline 313, is reheated by the heating element, and is pumped back into the heat exchange medium channel. This cycle is repeated to achieve the effect of the heat tank 3 heating the inlet water channel.

[0058] In one embodiment, the heat exchange device 2 includes multiple water flow channels and multiple heat exchange medium channels. Each water flow channel and each heat exchange medium channel is isolated from each other. Adjacent water flow channels can be interconnected, and adjacent heat exchange medium channels can be interconnected. A water flow channel is sandwiched between adjacent heat exchange medium channels. That is, the water flow channels and heat exchange medium channels are alternately arranged, and the water flow channels and heat exchange medium channels are not interconnected. Each water flow channel can be interconnected, and each heat exchange medium channel can be interconnected. With this arrangement, both sides of the water flow channel are heated by the heat exchange medium channel, which effectively improves the heat exchange efficiency between the heat exchange medium channel and the water flow channel.

[0059] Specifically, the heat exchange device 2 includes multiple heat-conducting structures, which are stacked together. A heat exchange medium channel is formed between two adjacent heat-conducting structures. Each heat-conducting structure has a water flow channel inside. The heat-conducting structure is plate-shaped or sheet-shaped, which increases the contact area between the water flow channel and the heat exchange medium channel. The heat-conducting structure can be made of materials with high thermal conductivity, such as metal, to achieve efficient heat transfer.

[0060] In one embodiment, the hot tank 3 can also be equipped with a pressure relief valve and a temperature sensor. When the exhaust pipe is blocked, the pressure inside the hot tank 3 becomes too high. When the pressure exceeds the pressure value set by the pressure relief valve, the pressure relief valve will automatically open to release the excess pressure, thereby ensuring that the pressure inside the hot tank 3 is always within a safe range. The temperature sensor can be electrically connected to the heating element through the control system. The temperature sensor is used to monitor the temperature inside the hot tank 3. When the temperature exceeds the preset temperature, the temperature sensor transmits the temperature information to the control system, and the control system controls the heating element to stop heating. When the temperature decreases, the temperature sensor transmits the temperature information to the control system, and the control system controls the heating element to start heating, ensuring that the heat exchange medium inside the hot tank 3 is always at the specified temperature, and can effectively exchange heat with the water flow in the water flow channel.

[0061] Unlike existing technologies, this application provides a water supply device, including an inlet pipe 1, a heat exchange device 2, and a heat tank 3. The heat exchange device 2 is provided with a water flow channel and a heat exchange medium channel that are isolated from each other, and the inlet pipe 1 is connected to the water flow channel. The heat tank 3 is used to contain the heat exchange medium, and the heat tank 3 is connected to a heat exchange power component 31 for making the heat exchange medium flow through the heat exchange medium channel. The heat tank 3 is provided with an exhaust port, and the exhaust port is connected to an exhaust component 4, which is thermally connected to the inlet pipe 1. Compared to existing technologies, this application includes a heating tank 3 and an exhaust component 4. The heating tank 3 primarily exchanges heat with the water flow within the heat exchange device 2, raising the water temperature. This reduces the time required for the heater 5 to reheat the water to the set temperature, achieving instant hot water. Simultaneously, the exhaust port of the heating tank 3 discharges heat to the inlet pipe 1 through the exhaust component 4. The water flow exchanges heat with steam as it passes through the inlet pipe 1, raising its temperature. Therefore, the heating tank 3 and heater 5 only need to heat the water to the set temperature in a short time, facilitating the use of steam in the heating tank 3 to heat the water flow, significantly improving heating efficiency. Furthermore, the immediate discharge of steam from the heating tank 3 ensures normal internal pressure, preventing disruption to its normal operation. Additionally, the inlet pipe 1 cools and condenses the steam, causing it to condense into water droplets that flow back into the heating tank 3 along the exhaust component 4, replenishing the tank and compensating for the heat exchange medium consumed during the heat exchange process.

[0062] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
