Description

Technical Field

[0001] This utility model relates to the field of water treatment devices, and in particular to a water system and drinking water equipment. Background Technology

[0002] With societal development, people have increasingly higher demands for water quality. Currently, drinking water equipment can purify public water sources and conveniently supply drinking water to users. This equipment uses filtration technology to remove impurities, bacteria, heavy metals, and organic matter from the water. The filtered drinking water can flow directly from the tap as room temperature drinking water. Additionally, some equipment includes heating and cooling units to heat or cool the drinking water. Drinking water equipment is widely used in homes, offices, shopping malls, factories, and other places.

[0003] Currently, the heating units in water dispensers typically employ an open or atmospheric pressure design, releasing steam through exhaust pipes to control pressure. This limits the heating temperature to the atmospheric boiling point of water. Furthermore, continuous steam emission leads to energy waste, and at the water outlet, the mixture of high-temperature water and steam can easily cause steam splashing, posing a risk of scalding and resulting in a poor user experience.

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0042] Although the present invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0043] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0044] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0045] Current water dispensers typically employ open or atmospheric pressure designs for their heating units, releasing steam through exhaust pipes to control pressure. This limits the heating temperature to the atmospheric boiling point of water. In high-altitude, low-pressure regions, the boiling point of water decreases. In these areas, the maximum temperature the heating unit can reach is generally 90°C, insufficient to provide superheated boiling water. This results in limited applicability of the dispensers; for example, brewing certain teas requires higher temperatures, failing to meet users' needs for hot water. Furthermore, continuous steam emission wastes energy, and the mixture of high-temperature water and steam at the outlet can cause steam splashing, posing a scalding risk and negatively impacting the user experience. Additionally, switching between room temperature and hot water in the dispenser is slow because both share a portion of the outlet pipe.

[0046] This utility model provides a water system and drinking water equipment that can solve some or all of the technical problems in the above-mentioned related technologies.

[0047] Please refer to Figure 1 , Figure 2 and Figure 3, Figure 1 This is a schematic diagram of a water system provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of water flow in a water system according to an embodiment of the present invention, wherein the black arrows indicate the direction of water flow. Figure 2 The diagram shows the water flow direction of boiling water from a water system. The water system may include: an inlet k1, a first water path 11, a heating water tank 21, a second water path 12, and a water tap 22. The inlet k1 can be connected to a water supply source, or it can be connected to the outlet of a water purification system, so that room temperature water can enter the water system through the inlet k1. The room temperature water can be tap water or purified water.

[0048] The inlet of the first water passage 11 is connected to the inlet k1, and the outlet of the first water passage 11 is connected to the inlet of the heating water tank 21. The outlet of the heating water tank 21 is connected to the inlet of the second water passage 12, and the outlet of the second water passage 12 is connected to the water tap 22. The second water passage 12 has a pressure relief valve 121, and the water tap 22 has a steam condensation assembly 221.

[0049] The room-temperature water entering the water system through inlet k1 can enter the heating water tank 21 through the first water passage 11, which can heat the room-temperature water. The heated water or boiling water can flow to the water outlet 22 through the second water passage 12 for user use.

[0050] Since the heating water tank 21 is only connected to the outside world through the first water passage 11 and the second water passage 12, the heating water tank 21 in this embodiment of the present invention can be a closed heating water tank 21. Thus, the closed heating water tank 21 can heat water in an environment higher than normal pressure, and the boiled water temperature can exceed 100℃ (for example, reaching 105℃~110℃). Furthermore, it can heat room temperature water to boiling point more quickly, thereby improving the heating efficiency of the water system and producing high-temperature boiling water to meet users' needs for brewing tea, coffee, etc. The closed heating water tank 21 also reduces heat loss, resulting in faster and more energy-efficient water heating.

[0051] Furthermore, the pressure in the heating water tank 21, the first water circuit 11, and the second water circuit 12 can be precisely controlled by the pressure relief valve 121. The pressure relief valve 121 can remain closed under normal conditions to increase the temperature in the heating water tank 21. When the pressure in the water system exceeds the limit, the pressure relief valve 121 can automatically release pressure, thus ensuring system safety while heating under high pressure. For example, the pressure relief valve 121 can be a mechanical pressure relief valve 121 or an electromagnetic pressure relief valve 121.

[0052] In addition, by integrating a steam condenser 221 into the faucet 22, the steam generated during the boiling water delivery process can be condensed into liquid water before flowing out. This ensures that the water flowing out of the faucet 22 is a high-temperature liquid, rather than a gas-liquid mixture, thus preventing steam from splashing and scalding users and improving the safety and user experience of the water system.

[0053] In summary, this utility model embodiment provides a water system including an inlet k1, a first water path 11, a heating water tank 21, a second water path 12, and a water outlet 22. The inlet of the first water path 11 is connected to the inlet k1, and the outlet of the first water path 11 is connected to the inlet of the heating water tank 21. The outlet of the heating water tank 21 is connected to the inlet of the second water path 12, and the outlet of the second water path 12 is connected to the water outlet 22. The second water path 12 includes a pressure relief valve 121, and the water outlet 22 includes a steam condenser assembly 221. The sealed heating water tank 21 allows water to be heated at a pressure higher than normal, thereby improving the heating efficiency of the water system and enabling the preparation of high-temperature boiling water. Furthermore, the pressure relief valve 121 ensures system safety. Furthermore, by integrating a steam condenser 221 into the faucet 22, the steam generated during the boiling water delivery process can be condensed into liquid water before flowing out, thereby preventing steam from splashing and scalding users, and improving the safety and user experience of the water system.

[0054] Please refer to Figure 3 , Figure 3 This is a partial cross-sectional structural diagram of a faucet 22 provided in an embodiment of the present invention. In an optional embodiment, the faucet 22 may include a faucet body 222 and a mounting part 223. The mounting part 223 is located at the end of the faucet body 222 and is connected to the faucet body 222. The faucet body 222 has a first water passage d1, and the mounting part 223 has a mounting through hole d3. A steam condensing assembly 221 is installed in the mounting through hole d3 and has a second water passage d2, which communicates with the first water passage d1. Boiling water flowing out of the faucet body 222 can then flow out of the faucet through the steam condensing assembly 221. That is, by placing the steam condensing assembly 221 at the outlet of the faucet 22, the steam in the flowing boiling water can be quickly condensed into water, preventing water vapor from splashing out and improving the user experience of the water system.

[0055] In one optional embodiment, the steam condensation assembly 221 may include a condensation shell 2211 and a mesh structure 2212; the condensation shell 2211 is located in the mounting through hole d3 and connected to the mounting part 223, the condensation shell 2211 has a second water passage d2 and a plurality of air inlets x1, and there is an air inlet gap x2 between the condensation shell 2211 and the hole wall of the mounting through hole d3, the air inlet gap x2 is connected to the second water passage d2 through the plurality of air inlets x1; the mesh structure 2212 is installed in the second water passage d2.

[0056] A gap exists between the inner wall of the condenser housing 2211 and the mounting part 223, allowing the first water passage d1 in the condenser housing 2211 to communicate with the outside atmosphere through multiple air inlets x1. When high-temperature steam flows through the steam condensation assembly 221, a Venturi negative pressure effect is formed at the outlet of the water passage. Driven by the pressure difference, external air is actively drawn in sequentially through the air inlet gap x2 and the multi-stage air inlets x1, mixing with the steam and enhancing turbulent exchange, thereby achieving efficient forced convection condensation. The water flowing out of the faucet body 222 after steam condensation must pass through the mesh structure 2212 installed in the first water passage d1. The mesh structure 2212 provides a large contact surface area to accelerate the steam condensation process and also serves as a gas-liquid separator.

[0057] For example, the intake gap x2 can be an annular gap, and the intake hole x1 can be a strip-shaped through hole, with multiple strip-shaped through holes evenly arranged along the circumference of the condenser housing 2211. The width of the intake hole x1 can range from 0.5 mm to 5 mm, and the length of the intake hole x1 can range from 1 mm to 10 mm. The number of intake holes x1 on the condenser housing 2211 can be 2 to 6. For example, the width of the intake hole x1 is 0.5 mm, 1 mm, 1.6 mm, 2.8 mm, 4 mm, or 5 mm, the length of the intake hole x1 is 1 mm, 2 mm, 5 mm, 6 mm, 8.5 mm, or 10 mm, and the number of intake holes x1 on the condenser housing 2211 is 2, 3, 4, 5, or 6.

[0058] In one optional embodiment, the mesh structure 2212 may include a plurality of mesh portions w1, all of which are installed in the first water passage d1. The plurality of mesh portions w1 are arranged along the axial direction of the first water passage d1, and the mesh holes in the plurality of mesh portions w1 are staggered along the axial direction of the first water passage d1.

[0059] The mesh portion w1 can be a metal mesh, and multiple mesh portions w1 can form a multi-layer metal mesh structure. The mesh density of the mesh portion w1 can range from 10 mesh to 120 mesh, and the minimum spacing between two adjacent mesh portions w1 ranges from 0.5 mm to 3 mm. For example, the mesh density of the mesh portion w1 can be 10 mesh, 20 mesh, 50 mesh, 80 mesh, 100 mesh, or 120 mesh, and the minimum spacing between two adjacent mesh portions w1 can be 0.5 mm, 1.2 mm, 2 mm, 2.5 mm, or 3 mm.

[0060] In one exemplary embodiment, the plurality of mesh portions w1 may include a first mesh portion w1 and a plurality of second mesh portions w1, wherein the first mesh portion w1 is located on the side of the plurality of second mesh portions w1 away from the water outlet of the faucet 22, that is, the first mesh portion w1 can come into contact with the flowing liquid earlier. The shape of the first mesh portion w1 may be arc-shaped, and the middle area of ​​the first mesh portion w1 may be recessed toward the interior of the faucet body 222, thereby increasing the contact area between the water flow and the first mesh portion w1. The shape of the second mesh portions w1 may be flat.

[0061] In one exemplary embodiment, when high-temperature steam passes through multiple perforated mesh sections w1 arranged in layers, it is divided into countless fine airflows. The surface of the metal mesh provides numerous condensation initiation points for steam condensation, thereby drastically accelerating the phase change (gas-to-liquid) process and improving condensation efficiency. In other words, the multiple perforated mesh sections w1, by increasing the gas-liquid contact surface area and disturbing the flow field, promote gas-liquid mixing and achieve condensation.

[0062] Furthermore, the multi-layer mesh section w1, through its complex internal structure, can force the steam and cooling air to change their flow paths, ensuring that the vapor and liquid phases achieve full and uniform contact across the entire condenser cross-section. This eliminates flow dead zones, thereby maximizing the utilization of the effective volume of the steam condensation assembly 221 and improving the overall heat exchange efficiency.

[0063] In addition, the multi-layered mesh section w1 can also generate turbulent reorganization effect on the water flow, reducing the velocity of the outflowing water and thus reducing splashing.

[0064] Please refer to Figure 3In one exemplary embodiment, the faucet body 222 and the mounting part 223 can be threaded together, and the steam condensing component 221 can be snapped into the mounting part 223. During the assembly of the faucet 22, the steam condensing component 221 can be assembled into the mounting part 223 first, and then the mounting part 223 can be connected to the faucet body 222. Exemplarily, the inner wall of the mounting through hole d3 of the mounting part 223 has a first limiting step, and the outer wall of the condenser housing 2211 has a second limiting step. The first limiting step and the second limiting step can engage to install the steam condensing component 221 into the mounting part 223, thus facilitating the maintenance and replacement of the steam condensing component 221.

[0065] In one exemplary embodiment, the faucet 22 further includes an annular sealing gasket 224, which can be located between the condenser housing 2211 and the mounting part 223. The upper surface of the annular sealing gasket 224 can contact the faucet body 222, and the lower surface of the annular sealing gasket 224 can contact the end of the condenser housing 2211 and the mounting part 223. This allows the water inlet of the steam condenser assembly 221 to achieve a face seal with the water outlet of the faucet body 222, thereby enabling the water vapor mixture in the water system to completely pass through the multi-layer mesh part w1.

[0066] Please refer to Figure 1 and Figure 2 In one optional embodiment, the heating water tank 21 may include a tank body 211, an inlet pipe 212, an outlet pipe 213, a heating component 214, a first liquid level switch 215, and a second liquid level switch 216.

[0067] The housing 211 has a receiving chamber, into which the water inlet pipe 212, the water outlet pipe 213, and the heating component 214 all extend. The water inlet pipe 212 is connected to the first water passage 11, and the water outlet pipe 213 is connected to the second water passage 12. The water outlet end of the water inlet pipe 212 is lower than the water inlet end of the water outlet pipe 213. A baffle plate 2121 can also be provided at the end of the water inlet pipe 212 so that the room temperature water entering the water tank can be evenly distributed.

[0068] The housing 211 has a first through hole, a second through hole, and a third through hole communicating with the receiving chamber; the water inlet pipe 212 extends into the receiving chamber through the first through hole, the water outlet pipe 213 extends into the receiving chamber through the second through hole, and the heating component 214 extends into the receiving chamber through the third through hole; furthermore, the housing 211 also has a first sealing ring, a second sealing ring, and a third sealing ring, the first sealing ring being located between the water inlet pipe 212 and the first through hole, the second sealing ring being located between the water outlet pipe 213 and the second through hole, and the third sealing ring being located between the heating component 214 and the third through hole, thus improving the sealing performance of the heating water tank 21.

[0069] The heating assembly 214 may include a heating tube, which can heat the liquid to above 105°C in a sealed enclosure 211.

[0070] Both the first level switch 215 and the second level switch 216 are installed in the receiving chamber. The height of the first level switch 215 is greater than the height of the second level switch 216, and there is a gap between the first level switch 215 and the top of the receiving chamber. The water system may also include a control component. When the first level switch 215 is triggered, the control component can close the first water passage 11 to prevent the water flow in the tank from exceeding the preset height. Furthermore, it can retain a partial cavity in the upper part of the tank, thus facilitating the formation of a high-pressure environment in the tank.

[0071] The heating water tank 21 may also include a first temperature sensor 217 and a second temperature sensor 218. Both the first temperature sensor 217 and the second temperature sensor 218 are installed in the receiving chamber. The height of the first temperature sensor 217 is greater than the height of the second temperature sensor, which can improve the accuracy of temperature measurement.

[0072] Please refer to Figure 1 and Figure 4 , Figure 4 yes Figure 1 Another schematic diagram of the water flow in the water system shown is as follows: Figure 4 The diagram shows the direction of hot water flow in the water system. In an optional embodiment, the water system may further include a regulating valve t1, a third water path 13, and a fourth water path 14. The regulating valve t1 has a first inlet, a first outlet, and a second outlet. The first inlet of the regulating valve t1 is connected to the inlet k1, the first outlet of the regulating valve t1 is connected to the inlet of the third water path 13, and the second outlet of the regulating valve t1 is connected to the inlet of the first water path 11. The outlets of the third water path 13 and the second water path 12 are both connected to the inlet of the fourth water path 14, and the outlet of the fourth water path 14 is connected to the faucet 22.

[0073] The regulating valve t1 can be a single-inlet, two-outlet electromagnetic regulating valve t1, and the water output ratio of the first outlet and the second outlet can be infinitely adjusted. Setting the regulating valve t1 before the heating water tank 21 can reduce the temperature resistance requirements of the regulating valve t1 and also avoid the problem of short lifespan caused by frequent adjustment of the valve t1 when it is set after the heating water tank 21.

[0074] Thus, if the first water path 11, the second water path 12 and the third water path 13 all flow out and converge into the fourth water path 14, hot water can be formed in the fourth water path 14. Furthermore, by controlling the flow rate of the first water path 11 and the third water path 13 through the regulating valve t1, the temperature of the hot water in the fourth water path 14 can be adjusted, and the hot water in the fourth water path 14 can flow out through the water outlet faucet 22.

[0075] In one optional embodiment, the first water path 11 may include a first pipe and a first check valve 111. The inlet end of the first pipe is connected to the second outlet end of the regulating valve t1, and the first check valve 111 is installed on the first pipe. The first water path 11 may also include a filter structure 112 installed on the first pipe for further filtration of the liquid entering the heating water tank 21. The second water path 12 may include a second pipe and a pressure relief valve 121. The two ends of the second pipe may be connected to the heating water tank 21 and the fourth water path 14, respectively, and the pressure relief valve 121 is installed on the second pipe. The third water path 13 includes a third pipe and a second check valve 131. The inlet end of the third pipe is connected to the first outlet end of the regulating valve t1, and the second check valve 131 is installed on the third pipe. Both the first check valve 111 and the second check valve 131 can be used to prevent backflow when boiling water is dispensed.

[0076] In one optional embodiment, the fourth water path 14 may include a fourth pipe and a temperature detection unit 141; the inlet of the fourth pipe is connected to the second water path 12 and the third water path 13 respectively, and the outlet of the fourth pipe is connected to the faucet 22; the temperature detection unit 141 is installed on the fourth pipe and is electrically connected to the regulating valve t1. The control component may be electrically connected to the faucet 22, the regulating valve t1 and the temperature detection unit 141. The temperature detection unit 141 may be a temperature sensor (NTC). The user can select the outlet water temperature at the faucet 22. The control component can adjust the water flow of the first outlet and the second outlet of the regulating valve t1 according to the outlet water temperature to form hot water, and the hot water temperature is fed back in real time through the temperature sensor. When the temperature of the hot water in the fourth water path 14 is too high, the water flow of the first outlet (that is, the water flow of the third water path 13) can be increased and the water flow of the second outlet (that is, the water flow of the first water path 11) can be decreased to achieve the purpose of lowering the outlet water temperature.

[0077] Please refer to Figure 1 and Figure 5 , Figure 5 yes Figure 1 Another schematic diagram of the water flow in the water system shown is as follows: Figure 5 The diagram shows the direction of water flow from the water system to the room temperature water outlet. In an optional embodiment, the water system may also include a fifth water channel 15 and a sixth water channel 16.

[0078] The inlet ends of the fifth water passage 15 and the sixth water passage 16 are both connected to the inlet k1.
