Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of container heating, in particular to a heating normal-pressure liquid storage device and a water heater using the same. BACKGROUND

[0002] When a closed container loaded with liquid is actively heated or passively heated, the gasification of part of the liquid will increase the internal pressure of the closed container, thereby putting higher requirements on the pressure-bearing capacity of the closed container, and the field of electric water heaters is a relatively typical application scenario.

[0003] When the electric water heater heats the water in the inner container, the pressure in the inner container will rapidly rise because the inner container is in a closed state, which puts higher requirements on the quality of the inner container, and a safety component such as a pressure relief valve also needs to be provided. Specifically, the inner container of the electric water heater in the prior art is mostly a metal welded inner container, and the service life of the weld will be greatly shortened when bearing pressure, and once the inner container weld leaks, it cannot be repaired and can only be disposed of as a whole. If the pressure in the inner container exceeds the standard, the pressure relief valve will discharge the gas in the inner container to rapidly relieve pressure and produce an abnormal sound, thereby affecting the user experience. SUMMARY

[0004] In view of the deficiencies in the prior art, the purpose of the present application is to provide a heating normal-pressure liquid storage device and a water heater using the same. The present application realizes the adjustment of the low pressure bearing or even zero pressure bearing relative to the atmospheric pressure of the container in various states, especially when the container is closed and heated, in addition to the internal liquid pressure, by using the overflow water during use, no water during non-use, and the constant pressure release to the outside. The service life of the container is prolonged.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions:

[0006] A heating normal-pressure liquid storage device, comprising a container for storing liquid, and a water inlet channel and a water outlet channel connected and communicated with the container, the water inlet channel comprising a water inlet main pipe communicated with the bottom space of the container and a liquid source outside, and the water outlet channel comprising a water outlet main pipe penetrating from the bottom of the container and communicated with the top space of the container and the space outside.

[0007] The container is provided with a heating component inside or outside.

[0008] As an embodiment of the present application, when the liquid inside the container is heated, part of the gasified liquid will be discharged to the outside through the top of the water outlet main pipe, realizing the continuous balance of the internal gas pressure of the container and the atmospheric pressure outside, so that the container has no additional pressure in addition to the internal liquid pressure, thereby prolonging the service life of the container. Correspondingly, if the container needs to discharge the liquid after heating, only after a certain amount of liquid is injected into the container through the water inlet main pipe, the high-temperature liquid at the top of the container will be lifted and discharged in a overflow manner through the water outlet main pipe.

[0009] Preferably, the water outlet main pipe is connected with two water outlet branch pipes through a regulating valve, and the water outlet main pipe is connected with the outside space through the two water outlet branch pipes selectively.

[0010] As an embodiment of the present application, in order to prevent the high-temperature gaseous liquid from hurting people in some special cases, such as the state of no liquid inflow, the water outlet main pipe is connected with two water outlet branch pipes for liquid discharge and gas discharge respectively, and the water outlet branch pipe for gas discharge can be directly introduced into the directional space. Of course, in the state of liquid inflow and heating, the gaseous liquid is also discharged, but due to the mixing of the newly-inflowed liquid and the heated liquid, the amount of gaseous liquid discharged is small and the temperature is low, which is close to the state of volatilization or natural evaporation, and the high-temperature hurting phenomenon does not occur.

[0011] Preferably, the water inlet main pipe is further provided with a water inlet branch pipe connected with the water outlet branch pipe, and the water inlet main pipe is further provided with a water mixing valve for distributing the flow of the liquid source into the container and the water inlet branch pipe.

[0012] As an embodiment of the present application, the water mixing valve is provided to realize one-in-two-out of the liquid source, that is, one way into the container and the other way into the water outlet branch pipe for liquid discharge to mix and adjust the temperature of the discharged high-temperature liquid or into the water outlet branch pipe for gas discharge to cool the discharged high-temperature gaseous liquid. Of course, the liquid in the water inlet branch pipe can enter both water outlet branch pipes at the same time, or no liquid enters both water outlet branch pipes under the adjustment of the water mixing valve.

[0013] The water mixing valve can adopt the conventional water mixing valve structure in the field of water heaters, except that the conventional water mixing valve structure is two-in-one-out, while the water mixing valve in the present application is one-in-two-out, and the specific water inlet and outlet connection mode can be adjusted. Of course, the water mixing valve in the present application can also be one-in-three-out, one-in-four-out, or one-in-multiple-out structure, that is, in addition to distributing the liquid source into the water inlet branch pipe and the container, the liquid source can also be adjusted and distributed to other branch pipes, but it should be emphasized that the water mixing valve should at least meet the connection effect of supplying water to the container or / and the water inlet branch pipe respectively.

[0014] As another embodiment of the present application, the water inlet branch pipe can be directly connected with the water outlet branch pipe for liquid discharge, and the adjustment effect of the water mixing valve of the present application is as follows:

[0015] 1) The user needs more high-temperature liquid discharge, and rotates the water mixing valve to the limit state A to adjust the liquid source to enter the container completely, so that the container is in a large amount of liquid discharge state, the water inlet branch pipe has no liquid inflow, and the temperature of the discharged high-temperature liquid cannot be lowered to meet the user's demand;

[0016] 2) User does not need high-temperature liquid discharge or user does not use the device, rotate the mixing valve to the limit state B, the liquid source cannot enter the container and the water inlet branch pipe, and the container cannot overflow and discharge liquid;

[0017] 3) User needs mixed-temperature high-temperature liquid discharge, gradually adjust the mixing valve from the limit state B to the limit state A, the mixing valve controls the liquid source to enter the container and the water inlet branch pipe at the same time, and the closer the mixing valve is to the limit state A, the less liquid enters the water inlet branch pipe and the more liquid enters the container, thereby meeting the user's needs (because the amount of liquid directly discharged is fixed as long as the liquid begins to enter the water inlet branch pipe or / and the container, so the adjustment of the mixing valve towards the limit state A can only represent that the user has a higher demand for the temperature of the final discharged liquid, so the water inlet branch pipe does not need to enter too much water for mixing and cooling).

[0018] Preferably, the regulating valve is a four-way valve, and the four channels of the four-way valve are connected with the water inlet branch pipe, the water outlet main pipe and the two water outlet branch pipes respectively, and the valve core of the four-way valve makes the water outlet main pipe selectively communicate with the two water outlet branch pipes.

[0019] As an embodiment of the present application, the four-way valve is directly arranged and integrated with the corresponding pipelines, so that the water outlet main pipe can be controlled to selectively discharge air and liquid through the two water outlet branch pipes in different states, thereby greatly simplifying the mechanism.

[0020] Preferably, the four-way valve is provided with two normally open valve ports and is connected with the water inlet branch pipe and the water outlet main pipe respectively, and the other two valve ports of the four-way valve are connected with the two water outlet branch pipes respectively.

[0021] The action input end of the valve core of the four-way valve is connected with the action output end of the mixing valve through signal or mechanism transmission.

[0022] As an embodiment of the present application, the action of the valve core of the four-way valve and the adjusting action of the mixing valve are realized in association, wherein the action input end of the valve core of the four-way valve refers to the action of controlling the action of the valve core of the four-way valve and realizing the communication or closure of the corresponding channels, and the action output end of the mixing valve refers to the completed state of the adjusting action of the mixing valve.

[0023] The completed state of the adjusting action of the mixing valve can be sensed by setting a PLC and corresponding monitoring components, and the corresponding information can be fed back to the action of the valve core of the four-way valve. The adjusting action of the mixing valve can also be converted into the action of the valve core of the four-way valve through a mechanical mechanism.

[0024] Meanwhile, after the action of the valve core of the four-way valve is completed, the water outlet main pipe is selectively communicated with the two water outlet branch pipes, and whether the water inlet branch pipe is filled with water and the amount of water are only adjusted by the mixing valve.

[0025] Preferably, the two water outlet sub-pipes are a hot water sub-pipe for outputting hot water and a cold water sub-pipe for outputting condensed water and gas respectively;

[0026] The water inlet sub-pipe and the container are in a state of no flow, and the valve core of the four-way valve is actuated to switch the water outlet main pipe from being communicated with the hot water sub-pipe to being communicated with the cold water sub-pipe.

[0027] As an embodiment of the present application, the functions of the two water outlet sub-pipes are embodied, and the user can select the components, space, etc. to be installed at the output ends of the two water outlet sub-pipes according to the specific application environment.

[0028] Preferably, the outer edge of the rotating part of the mixing valve is provided with a protrusion;

[0029] The valve core of the four-way valve is in a structure of an inner cavity tube with an expanded middle section and a gap at both ends penetrating a through hole pre-provided in the valve body, one end of the inner cavity tube is communicated with the water inlet sub-pipe, and the outer wall of the end part of the inner cavity tube is in a curved surface structure forming a sliding friction pair with the protrusion, and the other end of the inner cavity tube is communicated with the water outlet main pipe; a return spring is sleeved on the outer wall of the inner cavity tube close to the water outlet main pipe, and the both ends of the return spring are in contact with the inner wall of the valve body and the outer wall of the expanded part respectively;

[0030] The expanded part of the inner cavity tube cooperates with the gap between the inner cavity of the valve body, and the third hole and the fourth hole are respectively provided on the top and the bottom of the expanded part;

[0031] The valve body is respectively provided with a first hole for communicating with the hot water sub-pipe and a second hole for communicating with the cold water sub-pipe;

[0032] The protrusion of the valve body of the mixing valve is in contact with the valve core of the four-way valve and makes the valve core in a maximum stroke state, the water inlet sub-pipe and the container are in a state of no flow, and the second hole and the fourth hole are communicated, and the first hole and the third hole are not communicated.

[0033] As an embodiment of the present application, the adjustment action of the mixing valve is converted into the action of the valve core through a mechanical mechanism, specifically:

[0034] The limit state A of the mixing valve is a state that the protrusion is away from the valve core of the four-way valve and the protrusion and the valve core of the four-way valve are not in contact, at this moment, the valve core is in contact with the return spring, the first hole and the third hole are completely communicated, the second hole and the fourth hole are not communicated, and the liquid source input liquid completely enters the container→ the water outlet main pipe→ the third hole→ the first hole→ the hot water sub-pipe→ the user;

[0035] The limit state B of the water mixing valve is that the protrusion overcomes the elastic force of the reset spring and touches the valve core, and the valve core is in the maximum stroke state, the water inlet branch pipe and the container are in the state of no flow, the container has no liquid inlet and no liquid outlet, the second hole and the fourth hole are connected, the first hole and the third hole are completely not connected, and the high-temperature gaseous liquid in the container heated by the heater outlet main pipe, the fourth hole, the second hole, the cold water air pipe and the specified space outside.

[0037] The liquid enters the container, the heater outlet main pipe, the third hole, the first hole, the hot water branch pipe, and the user.

[0038] At the same time, the liquid enters the water inlet branch pipe, the third hole, the first hole, the hot water branch pipe, and the user.

[0039] The liquid accepted by the final user is the mixed temperature liquid.

[0040] Preferably, the valve core bulge part is fixed with a sealing ring outside the periphery of the third hole and the fourth hole, which touches the inner wall of the valve body.

[0041] As an embodiment of the present application, by arranging the sealing ring, it can be ensured that no liquid or / and gas enters the valve body when the valve body is output by the protrusion.

[0042] Preferably, the top end of the heater outlet main pipe has a gap with the inner wall of the top of the container. The gap provides a space for overflow water and exhaust.

[0043] The water heater using the low-pressure water storage device has the container as the inner container of the water heater, and the heater outlet main pipe is connected with the hot water output assembly and the floor drain through two water outlet branch pipes.

[0044] Compared with the prior art, the present application has the following advantages:

[0045] The present application realizes the adjustment of the low-pressure of the container in each state, especially the zero-pressure of the container in the closed heating state, by using the overflow water during use, no water during non-use, and the constant pressure exhaust to the outside. No safety valve or other pressure protection safety assembly is needed, which greatly simplifies the structure of the device and greatly reduces the production cost and safety in use.

Among them, the input end of the water inlet branch pipe 21 is connected with the water inlet main pipe 2 through the three-way mixing valve 22, the three-way mixing valve 22 is used to distribute the water flow of the water source into the inner container 1 and the water inlet branch pipe 21, the four channels of the four-way valve 4 are respectively connected with the water inlet branch pipe 21, the water outlet main pipe 3, the hot water branch pipe 31 and the cold water branch pipe 32, and the valve core of the four-way valve 4 makes the water outlet main pipe 3 selectively communicated with the hot water branch pipe 31 and the cold water branch pipe 32.

[0053] When the embodiment is used:

[0054] 1) The user needs more high-temperature water to be discharged, adjusts the four-way valve to control the four-way valve to communicate the water outlet main pipe and the hot water branch pipe to discharge liquid;

[0055] Rotate the mixing valve to the limit state A, adjust the water source to enter the inner container, then the inner container is in a large amount of liquid discharge state, the water inlet branch pipe has no liquid inlet, and it is also impossible to reduce the temperature of the high-temperature water discharged outside to meet the user's demand;

[0056] 2) When the user does not use it, adjust the four-way valve to control the four-way valve to communicate the water outlet main pipe and the cold water branch pipe to discharge gas;

[0057] Rotate the water mixing valve to the limit state B, the water source cannot enter the inner container and the water inlet branch pipe, and the inner container cannot overflow and drain; the gaseous water generated by the water in the inner container heated is discharged into the cold water branch pipe to the outside through the water outlet main pipe, keeping the inner container and the outside atmospheric pressure balanced;

Embodiment 2

[0060] The differences between this embodiment and embodiment 1 are as follows:

[0061] The three-way water mixing valve 22 is arranged on one side of the four-way valve 4, and a protrusion 23 is arranged on the outer edge of the rotating part of the three-way water mixing valve 22;

[0062] The spool of the four-way valve 4 is in a structure that the length middle section is expanded, the length two ends are through the gap of the inner cavity pipe 42 with a pre-opened through hole of the valve body 41, one end of the inner cavity pipe 42 is connected to the water inlet branch pipe 21 and the outer wall of the end of the inner cavity pipe 42 is in a curved surface structure which forms a sliding friction pair with the protrusion 23, and the other end of the inner cavity pipe 42 is connected to the water outlet main pipe 3; a reset spring 44 is arranged on the outer wall of the inner cavity pipe 42 close to the water outlet main pipe 3, and the two ends of the reset spring 44 respectively abut against the inner wall of the valve body 41 and the outer wall of the expanded part 43 of the spool;

[0063] The expanded part 43 of the spool cooperates with the inner cavity gap of the valve body 41, and the third hole 413 and the fourth hole 414 are respectively arranged on the top and the bottom of the expanded part 43, and the expanded part 43 of the spool is fixedly provided with a sealing ring 45 abutting against the inner wall of the valve body 41 outside the third hole 413 and the fourth hole 414.

[0064] The valve body is respectively provided with a first hole for connecting the hot water branch pipe and a second hole for connecting the cold water branch pipe on the top and the bottom;

[0065] The protrusion 23 of the three-way water mixing valve body abuts against the spool of the four-way valve 4 and makes the spool in the maximum stroke state, the water inlet branch pipe 21 and the inner container 1 are in a state of no flow, and the second hole 412 and the fourth hole 414 are connected, and the first hole 411 and the third hole 413 are not connected.

[0066] The second hole 412 and the fourth hole 414 are in a non-communicating state, and the first hole 411 and the third hole 413 are communicated.

[0067] The water inlet and outlet control method of the water heater is as follows:

[0068] 1) The user needs more high-temperature water discharge (such as bath water and adjusts the maximum temperature water outlet), rotates the rotating part of the three-way mixing valve 22 to the limit state A, that is, the protrusion 23 of the rotating part is away from the four-way valve core and the protrusion 23 and the four-way valve core are not in contact, at this moment, the four-way valve core moves under the action of the return spring 44, and the first hole 411 and the third hole 413 are completely communicated, and the second hole 412 and the fourth hole 414 are not communicated;

[0069] At the same time, the three-way mixing valve 22 controls the cold water entering the inner container 1, and the cold water entering the inner container 1 lifts the stored water in the inner container after heating and makes the hot water overflow into the water outlet main pipe 3 and flows into the valve core of the four-way valve 4. Since the second hole 412 and the fourth hole 414 are not communicated, they can only flow from the third hole 413→the first hole 411 to flow into the hot water branch pipe 31 and be received by the user;

[0070] In this state, the inner container 1 is in a maximum liquid discharge state, the water inlet branch pipe 411 has no liquid, and the temperature of the high-temperature water cannot be reduced to meet the user's needs;

[0071] 2) When the user does not use it, rotate the three-way mixing valve 22 to the limit state B, that is, the protrusion 23 overcomes the elastic force of the return spring 44 and touches the four-way valve 4 core, and the four-way valve 4 core is in the maximum stroke state, at this moment, the second hole 412 and the fourth hole 414 are communicated, and the first hole 411 and the third hole 413 are completely not communicated. At the same time, the three-way mixing valve 22 adjusts the water inlet branch pipe 21 and the inner container 1 to be in a state of no flow, and the inner container 1 has no liquid and no liquid discharge, and the water source cannot enter the inner container 1 and the water inlet branch pipe 21, and the inner container 1 cannot overflow and discharge liquid;

[0072] The heated high-temperature gaseous water in the inner container 1→the water outlet main pipe 3→the fourth hole 414→the second hole 412→the cold water air pipe 32→the drain and other specified spaces outside.

[0073] 3) The user needs to discharge mixed temperature water, gradually adjust the three-way mixing valve 22 from the limit state B to the limit state A, the protrusion 23 of the four-way valve 4 core from the maximum touch state to no contact, the second hole 412 and the fourth hole 414 from communication to non-communication, and the first hole 411 and the third hole 413 gradually increase the communication diameter, and the three-way mixing valve 22 controls the water source to enter the inner container 1 and the water inlet branch pipe 21 at the same time:

[0074] Water enters the inner container 1 → the outlet main pipe 3 → the third hole 413 → the first hole 411 → the hot water branch pipe 31 → the user; at the same time, water enters the inlet water branch pipe 21 → the third hole 413 → the first hole 411 → the hot water branch pipe 31 → the user, and the user finally receives mixed water.

[0075] The closer the three-way mixing valve 22 is to the limit state A, the less water enters the inlet water branch pipe 21, and the more water enters the inner container 1, thereby meeting the user's demand (because the amount of water directly discharged is fixed as long as water starts to enter the inlet water branch pipe or / and the inner container, so the adjustment of the mixing valve towards the limit state A can only represent that the user has a higher demand for the final discharged water temperature, so the inlet water branch pipe does not need to enter too much water for mixing and cooling). Embodiment 3

[0076] The difference between this embodiment and embodiments 1 and 2 is that the mixing valve is a four-way or more mixing valve, the inlet of the mixing valve is connected to the external water source, one outlet is connected to the inner container, one outlet is connected to the inlet water branch pipe, and the other outlets are respectively connected to other water-using components, such as a water gun, a water pipe, etc.
