Description

Technical Field

[0001] The utility model belongs to the field of water heating equipment, in particular to a hot water constant temperature maintaining component. Background Art

[0002] During operations at chemical terminals, warm water is often needed to flush or clean pipelines or cabins. Water in the temperature range of 40℃-60℃ is the most preferred cleaning temperature. It will not cause insufficient cleaning of grease and oil dirt due to low temperature, nor will it cause chemical instability of hazardous chemicals due to high temperature, leading to safety accidents.

[0003] Flushing or cleaning operations require a large amount of warm water, and ordinary instant water heaters cannot meet the water demand. After the warm water produced by the storage water heater is used up, the time required for reheating is too long, which reduces the operation efficiency. Therefore, it is necessary to provide a large-capacity hot water constant temperature maintenance component with stable stored water temperature. Utility Model Content

[0004] The utility model aims to provide a hot water constant temperature maintaining component to solve the technical problem that the amount of warm water required for flushing or cleaning operations is large, ordinary instant water heaters cannot meet the water demand, and the time required for reheating after the warm water produced by the storage water heater is used up is too long, which reduces the operating efficiency.

[0005] To achieve the above purpose, the specific technical solution of the utility model is as follows:

[0006] A hot water constant temperature maintenance component, comprising: a water tank: having a water storage chamber for storing water; a heater: having a heating liquid inlet pipe and a heating liquid outlet pipe connected to the water tank, configured to extract the water in the water tank, heat it into hot liquid, and return the hot liquid to the water tank; a pressure relief component: connected to the top of the water tank in the direction of water level rise, densely covered with pressure relief holes that directly connect the water storage chamber with the external environment; a water inlet pipe: the water inlet direction matches the water storage chamber, and has a switch component for detecting the liquid level in the water storage chamber to control the opening or closing of the water inlet pipe; a water outlet pipe: connected to the bottom of the water tank. Through such a design, the water inlet pipe maintains the total amount of water stored in the water tank in real time, and the heater maintains the temperature of the water in the water tank, so that the water tank always stores a sufficient amount of warm water for use.

[0007] Furthermore, the water tank comprises an outer box body and an inner box body, and a heat preservation layer is sandwiched between the outer box body and the inner box body. Through such a design, the heat preservation layer enhances the heat preservation capacity of the water tank and prevents the temperature of the warm water stored in the water tank from being lost quickly.

[0008] Furthermore, the water tank is also provided with a communicating vessel level gauge, the communicating vessel level gauge is connected to the water storage cavity, and a transparent layer is provided on the side of the communicating vessel level gauge away from the water tank. Through such a design, the liquid level in the water tank can be visualized, which is convenient for staff to observe.

[0009] Furthermore, the heater is an instant water heater.

[0010] Furthermore, the connection between the pressure relief component and the water tank gradually narrows in a direction away from the pressure relief component to form a liquid conducting channel, and the pressure relief hole is provided on the side wall of the pressure relief component, and the pressure relief hole includes at least two or more corners of 80°-100°. With such a design, a large amount of water vapor will be generated after the temperature of the water in the water tank rises, and the pressure relief hole can release the pressure in the water storage chamber to prevent safety accidents. The pressure relief component is made of metal material with a relatively low temperature, and water vapor will liquefy when it encounters the pressure relief component and passes through the pressure relief hole. The design of the liquid conducting channel and the pressure relief hole can recover most of the liquefied water vapor, thereby achieving the effect of saving water resources.

[0011] Furthermore, the pressure relief hole includes a first corner and a second corner along the gas discharge direction, the inner corner of the first corner faces the water tank, and the opening direction of the second corner is opposite to the first corner; the side wall of the pressure relief part is also provided with a recovery groove, the recovery groove connects multiple second corners along the vertical direction, and the bottom end of the recovery groove is connected to the inner cavity of the pressure relief part. Through such a design, the second corner will gather the liquefied water vapor in the pressure relief hole and then drip it into the recovery groove, further improving the recovery rate of water vapor.

[0012] Furthermore, the switch assembly includes a ball valve, an extended handle and a weighted float. The ball valve is arranged at one end of the water inlet pipe located in the water storage chamber. One end of the extended handle is fixed to the switch handle of the ball valve, and the other end is fixed to the weighted float. The weighted float is a seal and floats or falls in coordination with the liquid level in the water storage chamber. With such a design, the weighted float floats with the liquid level and drives the switch handle of the ball valve to rotate. When the liquid level is too low, the weighted float falls and opens the ball valve, and the water inlet pipe starts to supply water. When the liquid level rises to a predetermined position, the weighted float floats up to close the ball valve, and the water inlet pipe stops supplying water.

[0013] Furthermore, the heating liquid inlet pipe is provided with an electromagnetic valve pump, the water storage chamber is provided with a temperature sensor, and the electromagnetic valve pump is in signal communication with the temperature sensor. Through such a design, the temperature sensor detects the temperature of the water in the water tank, and if the temperature does not reach a preset value, the electromagnetic valve pump is turned on and the heater starts to work.

[0014] The beneficial effects of the utility model are as follows: the water inlet pipe maintains the total amount of water stored in the water tank in real time, and the heater maintains the temperature of the water in the water tank, so that a sufficient amount of warm water for use is always stored in the water tank.

[0022] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0023] like Figures 1 to 6 shown.

[0024] Example 1

[0025] A hot water constant temperature maintenance component, comprising: a water tank 1: having a water storage chamber 2 for storing water; a heater 5: having a heating liquid inlet pipe 3 and a heating liquid outlet pipe 4 connected to the water tank 1, configured to extract the water in the water tank 1, heat it into hot liquid, and return the hot liquid to the water tank 1; a pressure relief member 6: connected to the top of the water tank 1 in the direction of water level rise, and densely distributed with pressure relief holes 7 that directly connect the water storage chamber 2 with the external environment; a water inlet pipe 8: the water inlet direction is coordinated with the water storage chamber 2, and has a switch component for detecting the liquid level height in the water storage chamber 2 to control the water inlet pipe 8 to open or close; a water outlet pipe 9: connected to the bottom of the water tank 1.

[0026] The water tank 1 comprises an outer box body and an inner box body, and a heat-insulating layer 10 is sandwiched between the outer box body and the inner box body. The material of the heat-insulating layer 10 can be selected from one of rock wool, polyurethane rigid foam, phenolic board, polystyrene, polypropylene and rubber-plastic sponge.

[0027] The water tank 1 is also provided with a communicating vessel level gauge 11, which is connected to the water storage chamber 2, and a transparent layer 12 is provided on the side of the communicating vessel level gauge 11 away from the water tank 1. The communicating vessel level gauge 11 uses the communicating vessel principle, and the liquid level height in the communicating vessel level gauge 11 is synchronized with the liquid level height in the water tank 1.

[0028] The implementation of the above embodiment is as follows:

[0029] The water temperature required for flushing and cleaning operations is 40℃-60℃. Therefore, when the temperature of the water stored in the water tank 1 is lower than the minimum temperature of 40℃, the heater 5 starts to work, extracts the water in the water tank 1, heats it and then returns it to the water tank 1. After the heating starts, the heater 5 will heat the water in the water tank 1 to 60℃ and then stop heating. When the water in the water tank 1 drops below 40℃ again, the heating will be restarted to maintain the water temperature in this cycle.

[0030] Example 2

[0031] The connection between the pressure relief member 6 and the water tank 1 gradually narrows in a direction away from the pressure relief member 6 to form a liquid conducting channel 13. The pressure relief hole 7 is arranged on the side wall of the pressure relief member 6. The pressure relief hole 7 includes at least two or more corners of 80°-100°.

[0032] The pressure relief hole 7 includes a first corner 14 and a second corner 15 along the gas discharge direction, the inner corner of the first corner 14 faces the water tank 1, and the opening direction of the second corner 15 is opposite to the first corner 14;

[0033] The side wall of the pressure relief member 6 is further provided with a recovery groove 16 , which is connected to a plurality of second corners 15 in a vertical direction, and the bottom end of the recovery groove 16 is connected to the inner cavity of the pressure relief member 6 .

[0034] The implementation of the above embodiment is as follows:

[0035] When the temperature of the water in the water tank 1 rises, a large amount of water vapor will be generated, so the water tank 1 needs a pressure relief part 6 to discharge excess pressure. The water vapor will liquefy when it contacts the pressure relief part 6 made of metal material. The liquefied water vapor flows along the inner wall of the pressure relief part 6 to the liquid guide channel 13, and the liquid guide channel 13 guides the liquefied water vapor into the water tank 1.

[0036] Water vapor will also liquefy when passing through the pressure relief hole 7. The pressure relief hole 7 with a corner can increase the area for the liquefied water vapor to adhere, and the second corner 15 will gather the liquefied water vapor in the pressure relief hole 7 and then drip it into the recovery tank 16, further improving the recovery rate of the water vapor.

[0037] Example 3

[0038] The heater 5 is an instant water heater.

[0039] The switch assembly includes a ball valve 17, an extended handle 18 and a counterweight float 19. The ball valve 17 is arranged at one end of the water inlet pipe 8 located in the water storage chamber 2. One end of the extended handle 18 is fixed to the switch handle 20 of the ball valve 17, and the other end is fixed to the counterweight float 19. The counterweight float 19 is a sealing component and floats or falls in coordination with the liquid level in the water storage chamber 2.

[0040] The heating liquid inlet pipe 3 is provided with an electromagnetic valve pump 21 , and the water storage chamber 2 is provided with a temperature sensor 22 . The electromagnetic valve pump 21 is in signal communication with the temperature sensor 22 .

[0041] The implementation of the above embodiment is as follows:

[0042] The temperature sensor 22 detects the temperature of the water in the water tank 1 in real time. When the temperature is lower than 40°C, the solenoid valve pump 21 is controlled to open, and the heater 5 heats the water in the water tank 1. When the water in the water tank 1 is heated to 60°C, the temperature sensor 22 controls the solenoid valve pump 21 to close and stop heating.

[0043] When part of the water in the water tank 1 is used up, the weighted float 19 falls and opens the ball valve 17, and the water inlet pipe 8 starts to supply water. When the liquid level rises to a predetermined position, the weighted float 19 floats up and closes the ball valve 17, and the water inlet pipe 8 stops supplying water, thereby realizing automatic water replenishment of the water tank 1.

[0044] The extended handle 18 amplifies the force applied by the weighted float 19 to the switch handle 20 through its own weight through the lever principle, so that the weighted float 19 can open the ball valve 17 through its own weight.

[0045] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
