Abstract
Description
Technical Field
[0001] The present invention relates to a water storage device for a water heater, in particular to a water storage tank. The utility model also relates to a gas water heater. Background Art
[0002] The existing gas water heaters have unstable heating power, which leads to the water outlet temperature fluctuating (also known as the interlayer water phenomenon). In order to solve the problem of fluctuating water temperature, there is also the problem of long waiting time for hot water after boiling when the water flow is small, and the water temperature experience is particularly poor. The existing technology solves this problem by using a thermostatic tank (also known as a thermal pool). The thermostatic tank is connected to the water outlet pipe of the water heater. The hot water just boiled flows into the thermostatic tank and mixes with the water stored in the thermostatic tank before it can flow out. For related literature, please refer to the Chinese utility model patent "A constant temperature tank for a gas water heater" with patent number ZL201921494705.8 (authorization announcement number CN210772792U); you can also refer to the Chinese utility model patent "Thermal pool assembly and gas water heater containing it" with patent number ZL202022362003.3 (authorization announcement number CN 213362831 U); you can also refer to the Chinese invention patent application disclosure "Thermal pool device and water heater" with application number 202110012974.1 (application publication number CN 112747467 A).
[0003] The functions of existing water heaters are also diversified, and there are more and more water heaters with water purification functions. However, the existing water purification function is often achieved by installing a filter element on the water inlet or outlet pipe, which occupies the internal space of the water heater; some water heaters have a bubble water function, which fully mixes gas (such as air) with water under a certain pressure to form a gas-water mixed solution, and then releases the pressure through expansion, so that the gas dissolved in the water suddenly aggregates to form tiny microbubbles and appears milky white. The microbubble water formed in the process has a strong detergency. The pressure and heat generated when the microbubbles in the water burst can instantly eliminate and carry away dirt, achieving a deep cleaning effect. Existing microbubbles often need to be equipped with a special microbubble generating device. In addition, among the user pain points of water heaters, waterway noise has always been an industry problem. The existing technology generally covers the outer surface of the noise source or the inner surface of the water heater box with a layer of sound-absorbing material, but this does not solve the problem from the sound source itself.
[0004] The existing thermostatic tank has a relatively simple structure and a relatively single function. Currently, no utility model has been found that combines water purification, bubble water and noise reduction functions into the existing thermostatic tank. Utility Model Content
[0005] The first technical problem to be solved by the utility model is to provide a water storage tank which can reduce noise and produce bubble water in view of the above technical status quo.
[0006] The second technical problem to be solved by the present invention is to provide a gas water heater which can reduce noise and produce bubble water in view of the above technical status quo.
[0007] The technical solution adopted by the utility model to solve the first technical problem mentioned above is: a water storage tank, which has a water inlet interface, a water outlet interface and an air inlet interface, and is characterized in that a filter screen and an impeller capable of generating a vortex are provided in the water storage tank, the impeller is arranged close to the water outlet interface, and the filter screen is arranged close to the air inlet interface.
[0008] The impeller is rotatably arranged in the water storage tank through a bracket. Of course, the impeller can also be fixed, but it is preferred to be arranged in rotation.
[0009] The impeller is preferably specifically arranged in the following structure: the bracket includes an upper bracket and a lower bracket arranged in the water storage tank, a connecting shaft is connected between the upper bracket and the lower bracket, and the impeller is arranged between the upper bracket and the lower bracket and has an axial hole in the middle that is adapted to the connecting shaft.
[0010] Furthermore, the bracket and the impeller are both magnets and are arranged with opposite magnetic properties, and the impeller is suspended between the upper bracket and the lower bracket.
[0011] The filter screen and the impeller are both made of IPSE material, or the filter screen and the impeller have a surface layer made of IPSE material. IPSE (Ion Polarization System Energy) is a special multi-element alloy (copper-based catalyst alloy) for scale inhibition and descaling. It is an alloy material prepared by high-temperature smelting of 8 metal elements with different electronegativity, mainly copper, zinc, and nickel. By strictly controlling the composition ratio of various elements and adopting a special processing technology, the alloy material presents a columnar crystal structure with consistent orientation at the micron scale. And it is this columnar crystal structure that plays a decisive role-when the material comes into contact with water, it will release free electrons, and the free electrons will combine with the scale-forming calcium and magnesium cations in the water to prevent the combination of calcium and magnesium with acid ions, thereby achieving a scale inhibition effect. IPSE materials can be used for water purification. The incoming water is purified by flushing the filter screen and impeller of the IPSE material. Due to the material characteristics of IPSE, the stronger the turbulence, the better the purification effect.
[0012] The impeller has water holes to generate swirls, and water flows through the water holes to generate orderly swirls.
[0013] A filter cartridge is arranged in the water storage tank, and the filter cartridge comprises a filter screen at the bottom and a surrounding wall around the filter screen, and a gap is provided between the surrounding wall and the inner wall of the water storage tank.
[0014] The specific setting of the filter is achieved by using one of the following:
[0015] The first type is that a filter cartridge is arranged in the water storage tank, and the filter cartridge includes a filter screen at the bottom and a surrounding wall located around the filter screen, and a gap is provided between the surrounding wall and the inner wall of the water storage tank.
[0016] The second type is that a filter sleeve is arranged in the water storage tank, and the filter sleeve includes a filter screen at the bottom and a hollow filter frame located around the filter screen, and there is a gap between the filter frame and the inner wall of the water storage tank.
[0017] A noise reduction sleeve is provided inside the filter frame. The noise reduction sleeve is made of rubber. The noise reduction sleeve can absorb the noise of the liquid medium or solid structure in the water mixing tank and achieve damping noise reduction through its own vibration.
[0018] A positioning groove is formed around the filter screen at the bottom of the filter frame, and the bottom of the noise reduction sleeve is positioned in the positioning groove.
[0019] The top of the filter sleeve is provided with a baffle having holes capable of generating microbubbles. Filter material is placed in the space formed by the baffle, the noise reduction sleeve and the filter screen. The generation of microbubbles allows the water purification filter material in the water mixing tank to come into contact with the water more fully, thereby enhancing the water purification effect.
[0020] The water storage tank comprises an upper section, a middle section and a lower section connected in sequence, the diameter of the upper section increases from the outside to the inside, and the diameter of the lower section decreases from the inside to the outside. The design of the shrinking diameter of the water storage tank is conducive to reducing noise, and the shrinking inclination angle is preferably 45°. The water outlet interface is located on the upper section, and the water inlet interface and the air inlet interface are located on the lower section.
[0021] The technical solution adopted by the utility model to solve the above-mentioned second technical problem is: a gas water heater, characterized in that it includes a shell and a heat exchanger, a burner and a water storage tank arranged in the shell, the heat exchanger is connected to a cold water inlet pipe and a hot water outlet pipe, and the water storage tank is arranged in the hot water outlet pipe.
[0022] Furthermore, the air inlet interface of the water storage tank is connected to an air pump.
[0023] Furthermore, the water inlet interface of the water storage tank is provided with a water pump.
[0024] Compared with the prior art, the utility model has the following advantages: bubble water can be produced in the water tank through the double-layer action of the filter and the drainage holes in the impeller, which can improve the water purification efficiency and the detergency to achieve a deep cleaning effect. The impeller can produce swirl flow, comb the flow state, and have a noise reduction effect. Compared with irregular turbulence, swirl flow can be more fully in contact with the air, so that the entire fluid absorbs the air more evenly and thoroughly, and the bubble water produced will be more and more uniform. Integrating the noise reduction design and bubble water design in the water tank can improve the internal space utilization of the gas water heater. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

The heat exchanger 2a is connected to a cold water inlet pipe 4a and a hot water outlet pipe 5a, and the water tank 1 is arranged in the hot water outlet pipe 5a. The air inlet interface of the water tank 1 is connected to an air pump 6a. The water inlet interface of the water tank 1 is provided with a water pump 7a.
[0035] like Figure 2 and Figure 3 As shown, the water storage tank in this embodiment has a water inlet interface 16 , a water outlet interface 14 and an air inlet interface 15 , and an impeller 4 capable of generating a swirl flow is provided in the water storage tank 1 , and the impeller 4 is arranged close to the water outlet interface 14 .
[0036] The impeller 4 is rotatably arranged in the water tank 1 through the bracket 2.

The bracket 2 and the impeller 4 are both magnets and are arranged in opposite magnetic properties, and the impeller 4 is suspended between the upper bracket 21 and the lower bracket 22.
[0037] The impeller 4 has a water hole 41 to generate a swirl. The filter screen 51 and the impeller 4 have a surface layer made of IPSE material.
[0038] The water storage tank 1 comprises an upper section 11, a middle section 12 and a lower section 13 connected in sequence, the diameter of the upper section 11 increases from the outside to the inside, and the diameter of the lower section 13 decreases from the inside to the outside.
