Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment, and in particular to a water boiler. Background Art

[0002] In today's society, water boilers are widely used in homes, offices, public places and various commercial and industrial scenarios, providing hot water resources for people's daily lives and production operations.

[0003] Traditional water boilers have many drawbacks during operation. During the water inlet link, when water flows rapidly into the internal pipes, the high water pressure will have a strong impact on the pipe system, causing the pipe joints to loosen and the seals to wear. Over time, it is very easy to cause serious faults such as pipe ruptures and dripping. During the working process, after the water is heated, the water in the heating water tank is gradually converted into water vapor, causing the air pressure to continue to rise. However, most existing water boilers lack an air pressure regulating mechanism. Once the air pressure exceeds the limit, water vapor will flow into the water outlet of the water boiler. Due to gravity, the water vapor condenses into water droplets in the water outlet pipe and drips continuously from the water outlet, causing the water boiler to drip when heated.

[0004] In order to avoid dripping during heating, some water heaters have an exhaust pipe on them. The exhaust pipe is led out from the top of the water heater and then connected to the floor drain. Such products are difficult to install, and the odor from the sewer will return to the water heater. In addition, in some areas, the lack of floor drains restricts the installation of water heaters. Summary of the invention

[0008] When water is poured into the heating water tank, water flows into the heating water tank through the water inlet channel of the pipe connection assembly, and the water flow generates negative pressure in the pipe connection assembly, which causes the sealed flexible water storage container to deform and shrink;

[0009] When the heating water tank heats water, the water expands in the heating water tank, and the pressure in the heating water tank and the sealed flexible water storage container increases, causing the water in the heating water tank to flow into the sealed flexible water storage container, prompting the sealed flexible water storage container to return to its original state.

[0010] In combination with the first aspect, the present invention further provides a first implementation of the first aspect, a heating system, wherein the heating system is installed at the bottom of the heating water tank and is used to heat the water in the inner tank;

[0018] an accelerating pipeline, wherein a water inlet of the accelerating pipeline is connected to the flange, and a water outlet of the accelerating pipeline is located in the first interface channel and connected to the connector;

[0019] A speed reduction pipeline, wherein the water inlet of the speed reduction pipeline is connected to the connector through the second interface channel, and the water outlet of the speed reduction pipeline is connected to the water inlet of the heating water tank;

[0020] The third interface channel is connected to the water inlet of the auxiliary water tank;

[0021] The acceleration pipeline is located at one end of the first interface channel and extends beyond the first interface channel. There is a gap between the acceleration pipeline and the deceleration pipeline.

[0022] In combination with the first aspect, the present invention also provides a fourth implementation of the first aspect, wherein the accelerating pipeline comprises a first conical tube and a cylindrical tube connected in sequence, and the aperture of the first conical tube gradually decreases along the direction from the first conical tube to the cylindrical tube.

[0023] In combination with the first aspect, the present invention further provides a fifth implementation of the first aspect, wherein the speed reduction pipeline is a second conical tube, and the aperture of the second conical tube gradually increases in a direction approaching the water inlet of the heating tank body.

[0024] In combination with the first aspect, the present invention further provides a sixth implementation of the first aspect, wherein the angle between the connector and the third interface channel is 60 to 120 degrees.

[0025] In combination with the first aspect, the present invention further provides a seventh implementation manner of the first aspect, wherein the distance between the water outlet of the acceleration pipeline and the water inlet of the deceleration pipeline is 3mm-8mm.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] A water boiler described in the present invention comprises: a heating water tank; a sealed flexible water storage container; a pipe connecting assembly, wherein the pipe connecting assembly is connected to the heating water tank, and the pipe connecting assembly constitutes a water inlet channel of the heating water tank; the pipe connecting assembly is connected to the sealed flexible water storage container, and the pipe connecting assembly can also constitute a reflux channel connecting the sealed flexible water storage container and the heating water tank; wherein, when water is filled into the heating water tank, water flows into the heating water tank through the water inlet channel of the pipe connecting assembly, and the water flow generates negative pressure in the pipe connecting assembly, and the negative pressure causes the sealed flexible water storage container to deform and shrink; when the heating water tank heats water, the water expands in the heating water tank, and positive pressure is generated in the heating water tank and the sealed flexible water storage container, and the positive pressure causes the water in the heating water tank to flow into the sealed flexible water storage container, prompting the sealed flexible water storage container to return to its original state.

[0028] 1. In the heating state, the hot water in the heating water tank can flow into the sealed flexible water storage container, thereby reducing the pressure in the heating water tank and preventing the water vapor in the heating water tank from gathering in the water outlet pipe of the heating water tank, causing the water boiler to drip.

DETAILED DESCRIPTION

[0038] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0039] like Figure 1 to Figure 5 As shown, the preferred structure of a water boiler described in the present invention.

[0040] As a common device that uses electric energy to heat water to boiling, electric water boilers are widely used in daily life and commercial places. Existing water boilers are usually equipped with a heating water tank, which is connected to the water inlet channel and the water outlet channel to achieve the inflow and outflow of water to meet people's demand for hot water. When the water in the heating water tank is heated, the water will gradually evaporate and produce water vapor, causing the air pressure inside the heating water tank to gradually rise. Traditional water boilers do not have effective air pressure balance measures, causing water vapor to flow into the water outlet of the water boiler, and under the action of gravity, condense into water droplets and flow down, resulting in the phenomenon of water boiler leakage. Once dripping occurs, it will not only cause a waste of water resources, but also may make the surrounding environment humid, causing safety accidents such as electrical short circuits, posing a threat to the personal safety and property safety of users.

[0041] In addition, some water boilers neglect to handle the water pressure flowing into the heating water tank in their designs. Since the heating water tank is directly subjected to the water pressure impact from the faucet for a long time and frequently experiences changes in water pressure in daily use, the fixing structure of the pipe connection gradually loosens, and the seals also wear out due to continuous friction. Over time, these problems will continue to accumulate, and eventually it is very easy to cause pipe ruptures, severe dripping and other faults, which not only increase the maintenance cost and replacement frequency of the equipment, but may also cause safety hazards such as scalding caused by hot water leakage, bringing great inconvenience and potential risks to users.

[0042] Example 1

[0043] The present embodiment provides a water boiler, which effectively solves the problems existing in the above-mentioned traditional water boilers. The installation position of the water boiler of the present invention is lower than the faucet, ensuring that the height difference between the two is at least 300mm. The water outlet of the water boiler is located at the top of its heating water tank 1, and the water outlet of the water boiler is directly connected to the faucet water outlet pipeline, and the faucet water outlet pipeline is connected to the atmosphere. When the user turns on the faucet, the water flows from top to bottom through the pipeline connection component 3 into the inner tank of the water boiler. In this process, when the water flow of the faucet flows from the water inlet pipeline 301 into the acceleration pipeline 302, according to the principle of fluid mechanics, the water flow speed will be accelerated, thereby forming a negative pressure zone at the gap between the water outlet of the acceleration pipeline 302 and the deceleration pipeline 304. The existence of this negative pressure zone significantly reduces the pressure of the inflowing water flow, effectively preventing excessive impact on the internal pipeline of the water boiler due to excessive water flow pressure, causing damage to the internal pipeline of the heating water tank 1 or dripping and other undesirable phenomena. When the water level inside the water boiler reaches the upper limit, the user turns off the faucet, and the water boiler starts to start the water boiling program. As the water boiling process continues, time goes by, and the water in the inner tank of the water boiler evaporates in large quantities, and more and more water vapor is generated, causing the air pressure inside the inner tank to rise sharply. At this time, the hot water in the inner tank will flow into the inner tank of the water boiler through the pipe connection component 3, thereby achieving balanced regulation of the air pressure inside the water boiler, effectively preventing water vapor from flowing into the water outlet of the water boiler, and being affected by gravity, condensing into water droplets and dripping from the water outlet, thereby causing the phenomenon of water dripping.

[0044] Based on the Venturi tube principle, when the water flows stably in the pipe connection assembly 3, the water flow of the faucet first flows into the water inlet pipe 301, and then flows into the heating water tank 1 through the acceleration pipeline 302, the connector 303 and the deceleration pipeline 304 in sequence. An interface channel is provided on the side of the connector 303, and the interface channel is connected to the water inlet of the sealed flexible water storage container 2. In the entire water flow system, when the total amount of water flow remains unchanged, since the aperture of the first conical tube of the acceleration pipeline 302 gradually decreases along the direction from the first conical tube to the cylindrical tube, the flow velocity of the water flow will be accelerated when passing through here. According to the Bernoulli principle, the pressure decreases as the flow velocity increases. Therefore, at the outlet of the acceleration pipeline 302 and after passing through the outlet of the acceleration pipeline 302, when the water quickly passes through the gap between the acceleration pipeline 302 and the deceleration pipeline 304 and enters the deceleration pipeline 304, a negative pressure will be generated near the outlet of the acceleration pipeline 302, that is, the formed cavity will form a vacuum area. In order to ensure that the pressure inside the sealed flexible water storage container 2 is always equal to the external pressure, the sealed flexible water storage container will present two different states, namely the first state and the second state. In the first state, since the pressure in the inner tank is relatively high, the pressure difference between the sealed flexible water storage container 2 and the inner tank is a negative value. At this time, the hot water in the inner tank will flow into the sealed flexible water storage container 2 through the pipe connection assembly 3 under the action of the pressure difference, so that the sealed flexible water storage container 2 is restored to its original state by the action of the internal air pressure. When the water flows into the water pipe, since the aperture size of the deceleration pipeline 304 gradually increases in the direction away from the acceleration pipeline 302, the water will flow into the inner tank in a more dispersed manner along the inner wall direction of the deceleration pipeline 304. This dispersed water flow form makes the water volume of the deceleration pipeline 304 larger. According to the continuity equation in fluid mechanics, the pressure will also decrease when the flow rate decreases, thereby further ensuring that the pressure of the water flowing into the inner tank is lower than the pressure when the water flows directly into the inner tank, reducing the pressure of the water flow from multiple links, and effectively preventing excessive water pressure from damaging the internal pipeline of the water boiler.

[0045] When the water flow into the inner tank reaches the upper limit, the water flow stops and the water boiler starts to boil water. As the boiling time gradually increases, water vapor in the inner tank of the water boiler continues to be generated and the amount increases, and the pressure in the inner tank also continues to increase. At this time, the hot water in the inner tank will flow back into the connector through the speed reduction pipeline 304. Since there is always a negative pressure area between the water outlet of the acceleration pipeline 302 and the water inlet of the speed reduction pipeline 304, part of the boiling water in the inner tank of the water boiler is sucked into the sealed flexible water storage container 2, thereby ensuring that the internal air pressure of the inner tank is always in a balanced state with the external air pressure. Since in the previous first state, the sealed flexible water storage container 2 has shrunk, thereby reducing the volume of the water storage cavity. When hot water continuously flows into the sealed flexible water storage container 2, making the internal pressure of the sealed flexible water storage container 2 gradually equal to the pressure of the inner tank, the sealed flexible water storage container 2 will gradually restore its deformation under the action of its own elasticity, thereby increasing the volume of the sealed flexible water storage container 2. At this time, the sealed flexible water storage container 2 successfully transforms from the first state to the second state, thereby achieving the balance of the pressure in the inner tank. In this process, the hot water in the water boiler can smoothly flow into the sealed flexible water storage container 2, effectively avoiding the water vapor condensing at the water outlet of the water boiler due to the excessive air pressure in the water boiler, causing the water boiler to drip.

[0046] In a specific implementation, in the first aspect, as Figure 1 to Figure 5 As shown, the present invention provides a water boiler, characterized in that it includes: a heating water tank 1; a sealed flexible water storage container 2; a pipe connecting component 3, wherein the pipe connecting component 3 is connected to the heating water tank, and the pipe connecting component 3 constitutes a water inlet channel of the heating water tank; the pipe connecting component 3 is connected to the sealed flexible water storage container 2, and the pipe connecting component 3 can also constitute a reflux channel connecting the sealed flexible water storage container 2 and the heating water tank 1; wherein, when water is filled into the heating water tank 1, water flows into the heating water tank through the water inlet channel of the pipe connecting component 3, and the water flow generates negative pressure in the pipe connecting component 3, and the negative pressure causes the sealed flexible water storage container 2 to deform and shrink; when the heating water tank 1 heats water, the water expands in the heating water tank 1, causing the pressure in the heating water tank 1 and the sealed flexible water storage container 2 to increase, thereby causing the water in the heating water tank 1 to flow into the sealed flexible water storage container 2, prompting the sealed flexible water storage container 2 to return to its original state.

[0047] In a specific implementation, in combination with the first aspect, the present invention further provides a first implementation of the first aspect, a heating system 4, the heating system 4 is installed at the bottom of the heating water tank 1, and is used to heat the water in the inner tank;

[0048] The load of the heating system 4 is less than 15w / cm 2In detail, in order to prevent some undesirable phenomena caused by excessive heating power of the heating system 4, such as a large amount of bottom boiling inside the heating water tank 1 during heating, which in turn causes a large amount of boiling water to flow back to the auxiliary water tank 2, causing the auxiliary water tank 2 to fail, etc., the load of the heating system 4 is controlled to be less than 15w / cm 2 The temperature control system 5 is installed in the middle of the side wall of the heating water tank 1 to control the water temperature in the inner tank; the temperature probe 6 is installed at the outlet of the heating water tank 1. In detail, the heating system 4 is used to control the heating of the water boiler. The temperature control system 5 can monitor the change of the water temperature in the heating water tank 1 in real time, and control the working state of the heating system 4 according to the preset temperature range to achieve the control of the water temperature, avoid the water temperature being too high or too low, and ensure that the user can get hot water of suitable temperature at any time, which improves the user experience. The temperature probe 6 is installed at the outlet of the heating water tank 1. Its function is to monitor the temperature of the hot water flowing out of the heating water tank 1 in real time, and feed back the water temperature data to the temperature control system 5, so that the system can adjust the heating system 4 and the temperature control system 5 according to the actual outlet water temperature, so as to ensure that the water temperature at the outlet of the water boiler is always stable at a higher standard.

[0049] In a specific implementation, in combination with the first aspect, the present invention also provides a second implementation of the first aspect, wherein the capacity of the sealed flexible water storage container 2 is not less than 1 / 10 of the capacity of the heating water tank 1. In detail, repeated tests have found that only when the capacity of the sealed flexible water storage container 2 is not less than 1 / 10 of the capacity of the heating water tank 1, the sealed flexible water storage container 2 can have sufficient space and capacity to fully accommodate the hot water flowing into the main heating water tank 1 during the heating process, thereby ensuring that the air pressure of the inner tank can be effectively balanced under various working conditions, ensuring the safe and stable operation of the water boiler.

[0050] In a specific implementation, in combination with the first aspect, the present invention further provides a third implementation of the first aspect, wherein the pipeline connection assembly 3 includes:

[0051] A connector 303, wherein the connector 303 includes a first interface channel, a second interface channel and a third interface channel that are interconnected;

[0052] A water inlet pipeline 301, one end of which is connected to an external water source, and the other end of which is connected to a flange;

[0053] An acceleration pipeline 302, wherein the water inlet of the acceleration pipeline 302 is connected to the flange, and the acceleration pipeline 302 is located in the first interface channel and connected to the connector 303;

[0054] A deceleration pipeline 304, wherein the deceleration pipeline 304 is connected to the connector 303 through the second interface channel;

[0055] The third interface channel is connected to the water inlet of the auxiliary water tank 2;

[0056] The acceleration pipeline 302 is located at one end of the first interface channel and its end surface exceeds the first interface channel, and there is a gap between the acceleration pipeline 302 and the deceleration pipeline 304 .

[0057] In a specific implementation, in combination with the first aspect, the present invention also provides a fourth implementation of the first aspect, wherein the acceleration pipeline 302 includes a first conical tube and a cylindrical tube connected in sequence, and the aperture of the first conical tube gradually decreases along the direction from the first conical tube to the cylindrical tube.

[0058] In this embodiment, the aperture of the first conical tube of the acceleration pipeline 302 gradually decreases along the direction from the water inlet pipeline to the water outlet pipeline, the maximum aperture of the first conical tube is equal to the inner diameter of the water inlet pipeline, and the minimum aperture of the aperture of the first conical tube is equal to the aperture of the cylindrical tube connected to the first conical tube. According to the continuity equation, when the cross-sectional area of ​​the pipeline is reduced, in order to ensure that the flow rate of the fluid remains unchanged, the flow rate of the water flow in the first conical tube increases, so that the water flow in the cylindrical tube maintains a relatively stable high-speed flow. The water source enters the acceleration pipeline 302 from the water inlet pipeline 301, which has an accelerating effect on the water source, thereby speeding up the flow rate of the water source, and the cylindrical tube is provided after the first conical tube so that the water source can flow smoothly after reaching a certain flow rate, ensuring that the water source has a stable flow rate when flowing out of the acceleration pipeline outlet, thereby generating a stable adsorption force, so that the water flow or air in the sealed flexible water storage container 2 is adsorbed and flows into the inner tank along with the water flow.

[0059] Specifically, the first conical tube is reduced from a hole diameter of at least 5 mm to a hole diameter of 1-2 mm at an angle of 15-30°, and the length of the cylindrical tube is 2-4 times the hole diameter of the cylindrical tube.

[0060] In a specific implementation, in combination with the first aspect, the present invention also provides a fifth implementation of the first aspect, wherein the deceleration pipeline is a second conical tube, and the aperture of the second conical tube gradually increases in the direction close to the water inlet of the heating tank. According to the Bernoulli principle, when water flows from the high-speed area into the second conical tube with a gradually increasing cross-sectional area, the kinetic energy is partially converted into pressure energy, thereby reducing the speed of the fluid. In detail, the aperture of the deceleration pipeline 304 gradually increases in the direction away from the acceleration pipeline 302 and close to the water outlet pipe. Such a setting is conducive to reducing the flow speed of the water source, while ensuring the smooth flow of the water flow, thereby preventing the water flowing into the water boiler from directly impacting the internal pipeline system of the water boiler, causing damage to its pipelines, and increasing the service life of the water boiler.

[0061] Specifically, the aperture of the speed reduction pipeline 304 is 2-3mm and is expanded to 6-10mm at an angle of 10-20°. Within this range, the smoothness of the water flow in the speed reduction pipeline 304 can be better guaranteed, and the impact of water pressure on the internal pipes of the water boiler can be better reduced.

[0062] In a specific implementation, in combination with the first aspect, the present invention further provides a sixth implementation of the first aspect, wherein the angle between the connector 303 and the third connecting channel is 60 to 120 degrees. Specifically, the angle formed by the connector 303 and the third connecting channel is within the range of 60 to 120 degrees, which can maximize the efficiency of the sealed flexible water storage container 2 in absorbing the boiling water in the heating water tank 1.

[0063] In a specific implementation, in combination with the first aspect, the present invention also provides a seventh implementation of the first aspect, wherein the distance between the water outlet of the acceleration pipeline 302 and the water inlet of the deceleration pipeline 304 is 3mm-8mm. The gap between the acceleration pipeline 302 and the deceleration pipeline 304 is in the range of 3mm-8mm. Within this range, the vacuum area of ​​the cavity can be increased to a larger area, thereby generating a stronger adsorption force and a better adsorption effect, which is conducive to avoiding the problem of blockage when the water source in the sealed flexible water storage container 2 enters the inner tank of the water boiler through the interface channel or the problem of blockage when the hot water in the inner tank of the water boiler is sucked into the sealed flexible water storage container.

[0064] In a specific implementation, the heating water tank 1 of the water boiler and the sealed water storage container 2 are connected by means of a pipe connection assembly 3 to construct a system for balancing the air pressure inside the water boiler. Compared with the traditional design of some water boilers in the past, which simply set an exhaust pipe at the top and directly connected it to the floor drain, this solution of using a sealed water storage container 2 to prevent dripping from the water outlet of the water boiler can not only effectively prevent the water quality inside the water boiler from being polluted and ensure the purity and health of the water used by users, but also from the installation level, the solution is more convenient and efficient to operate, greatly reducing the complexity and labor cost of installation, and bringing many conveniences to the production, installation and subsequent maintenance of the water boiler.

[0065] The working principle of the water boiler described in the present invention is: water is injected into the inner tank and heated, and the heated water is stored in the inner tank. When the user opens the valve to take water, a pressure difference is generated between the inner tank and the external environment. Driven by the pressure difference, the boiled water in the inner tank will flow out smoothly along the outlet pipe to meet the user's water demand. During the operation of the water boiler, when the water level inside the water boiler drops to the set lower limit value, the water boiler will stop the heating operation, and open the water inlet valve at the same time to re-inject water. With the continuous injection of water source, the water level gradually rises. When the water level reaches the preset upper limit value, the water inlet valve is closed, and the water boiler starts the heating program again to resume normal working state, and this cycle is repeated to ensure that hot water is continuously and stably provided to users.

[0066] For other structures of the water boiler described in this embodiment, refer to the prior art.

[0067] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
