Description

Technical Field

[0001] The present invention relates to the technical field of water dispensers, and in particular to a water vapor separation body and a water dispenser. Background Art

[0002] The household instant hot water purifier is very popular in the market and is widely used in daily life. The household instant hot water purifier uses RO reverse osmosis technology to filter tap water to make it drinkable directly. At the same time, this type of water purifier also has the function of instant heating. The filtered water is heated by a 2200W instant heating pipe, which can heat the filtered water in 3 seconds. It has multiple temperature options, which provides great convenience for people's daily life and ensures healthy drinking water.

[0003] However, existing household instant hot water dispensers also have some defects, which are manifested as: the use of instant hot water pipes to heat purified water will generate a large amount of steam, and when users take high-temperature water, steam and hot water are often discharged at the same time. Although some water dispensers have a steam exhaust structure on the water outlet, the steam exhaust effect is not ideal, and it is easy to exhaust steam in time. Some steam and hot water are still mixed and discharged from the water outlet, resulting in poor water shape, unstable water discharge, and steam spraying, etc., which may even scald users and bring inconvenience to users.

[0070] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0071] This embodiment provides a water vapor separator, which cooperates with a water dispenser to guide the water heated by the heating tube 400 for users to take. Figure 1 and Fig.11The water vapor separation body includes a box body 100, a water inlet pipe 300 and a water outlet pipe 200. The box body 100 has an inner chamber 101. The top surface of the box body 100 is provided with an exhaust port 102 connected to the inner chamber 101. The opposite ends of the bottom surface of the box body 100 are respectively provided with a water inlet 103 and a water outlet connected to the inner chamber 101. The water inlet pipe 300 is connected to the water inlet 103, and the water outlet pipe 200 is connected to the water outlet.

[0072] Among them, the box body 100 is provided with a converging structure for converging the water entering the inner chamber 101 from the water inlet pipe 300 to the side away from the water outlet; the water outlet includes a first water outlet 104 and a second water outlet 105, and the water outlet pipe 200 includes a first flow channel connected to the first water outlet 104 and a second flow channel connected to the second water outlet 105, and the first flow channel and the second flow channel are connected before the outlet of the water outlet pipe 200; the water gathered by the converging structure can flow out through the first flow channel or enter the first flow channel and the second flow channel respectively and then merge in front of the outlet of the water outlet pipe 200 and then flow out. Specifically, a first baffle 106 is provided between the first water outlet 104 and the second water outlet 105, and the first baffle 106 is higher than the first water outlet 104; when the water level in the inner chamber 101 is not higher than the first baffle 106, water flows out from the first water outlet 104, and when the water level in the inner chamber 101 is higher than the first baffle 106, water flows out from the first water outlet 104 and the second water outlet 105 at the same time.

[0073] When the user takes hot water, the water in the heating tube 400 flows upward into the water vapor separation body, and the water flows into the inner chamber 101. Under the action of the convergence structure, it first converges on the side of the inner chamber 101 away from the water outlet, and then flows out to the water outlet. At the same time, the water vapor moves upward and is discharged from the exhaust port 102 at the top of the box body 100. When the water flow is small, for example, when the user takes high-temperature water, the water level of the inner chamber 101 does not exceed the first baffle 106, and the water flows out from the first water outlet 104 through the first flow channel; when the water flow is large, for example, when the user takes warm water or room-temperature water, the water level of the inner chamber 101 exceeds the first baffle 106. In addition to flowing out from the first water outlet 104 through the first flow channel, the water will also cross the first baffle 106 and flow out from the second water outlet 105 through the second flow channel. Since the outlet of the first flow channel is located inside the second flow channel, the water flow from the first flow channel will merge with the water flow of the second flow channel before flowing out. From the user's perspective, the outflow is a stream of water, and there will be no bifurcated water flow, and the water shape is good. The setting of the convergence structure increases the length of the water flow from the water inlet to the water outlet, which is convenient for gas-liquid separation and convergence at the water outlet to form a stable water flow. The converging structure can converge small-flow water flows and then release them, avoiding intermittent water flow when the water flow is small, ensuring continuous and stable water flow, which is conducive to improving user experience.

[0074] See also Figure 5The water outlet pipe 200 may include an outer pipe 201 and an inner pipe 202, wherein the outer pipe 201 has a water channel 203 and a buffer chamber 204, and the inner pipe 202 is disposed in the water channel 203, wherein the inlet of the inner pipe 202 is connected to the first water outlet 104, and the outlet of the inner pipe 202 extends to the vicinity of the outlet of the water channel 203, and there is a flow gap 205 between the outer wall of the inner pipe 202 and the inner wall of the water channel 203, and the buffer chamber 204 is connected to the second water outlet 105 and the flow gap 205. The inner pipe 202 defines a first flow channel, and the buffer chamber 204 and the flow gap 205 constitute a second flow channel. The outlet of the inner pipe 202 is located in the water channel 203, and the distance between the outlet of the inner pipe 202 and the outlet of the water channel 203 is not greater than 0.5 mm. By arranging the outlet of the inner tube 202 in the sewer channel 203, the water flows out of the first flow channel and the second flow channel can be merged before rushing out of the outlet of the sewer channel 203 to form a confluence, thereby ensuring a beautiful water shape; and by reducing the distance between the outlet of the inner tube 202 and the outlet of the sewer channel 203, it is possible to prevent the water flow out of the inner tube 202 from hitting the inner wall of the outer tube 201 and causing splashing and bifurcated water flow.

[0075] Specifically, the first baffle 106 has a rear blocking portion 107 close to the second water outlet 105, and the rear blocking portion 107 is located above the cache cavity 204 or enters the cache cavity 204. A second baffle 206 is provided between the water channel 203 and the cache cavity 204, and a flow opening 207 is formed between the rear blocking portion 107 and the second baffle 206, so that water in the cache cavity 204 can flow over the second baffle 206 from the flow opening 207 and enter the flow gap 205.

[0076] The inner wall of the outer tube 201 is provided with a limiting structure, which positions the lower part of the inner tube 202 at the center of the cross section of the water channel 203. In a possible implementation, the limiting structure may include a step provided on the inner wall of the outer tube 201, the step supporting the lower end of the inner tube 202, and a flow gap between the inner tube 202 and the step, so that the water that has climbed over the second baffle 206 passes through the flow gap and merges with the water flowing out of the inner tube 202. In another possible implementation, Figure 5-Figure 6 As shown, the limiting structure may include a plurality of limiting ribs 208 spaced apart on the inner wall of the outer tube 201, each limiting rib 208 being distributed along the long axis of the outer tube 201, and a flow channel being formed between adjacent limiting ribs 208, the limiting ribs 208 abutting against the outer wall of the inner tube 202, and the water that has climbed over the second baffle 206 passes through the flow channel and merges with the water flowing out of the inner tube 202.

[0077] Please continue to see Figure 5, the lowest water level at the highest position on the inner tube 202 is the first critical water level 209, and the highest water level at the highest position on the inner tube 202 is the second critical water level 210. The first critical water level 209 is higher than the first water outlet 104, and the highest position on the first baffle 106 is higher than the second critical water level 210. As the water intake temperature of the water dispenser is higher, the instantaneous amount of water heated by the heating tube 400 is smaller, and a continuous and smooth waterway cannot be formed when the water is discharged, which will cause the water dispenser to have intermittent water discharge and erratic water shape when taking high-temperature water. In order to solve this phenomenon, the present embodiment constructs a siphon away from the necessary structural conditions and uses the siphon principle to help continuous water discharge. Figure 5 When the water level at the first water outlet 104 is higher than the first critical water level 209, a pressure difference is formed between the first water outlet 104 and the first critical water level 209. The pressure difference can be used to make the water at the first outlet flow downward continuously, forming continuous water outlet.

[0078] Please continue to see Figure 5 The first flow channel is provided with a first water storage area 211, and the second flow channel is provided with a second water storage area 212; when the inner chamber 101 stops supplying water to the first flow channel, the first water storage area 211 is filled with water to prevent external air from entering the inner chamber 101 from the first flow channel; when the inner chamber 101 stops supplying water to the second flow channel, the second water storage area 212 is filled with water to prevent external air from entering the inner chamber 101 from the second flow channel. The pipe section between the inlet on the inner pipe 202 and the first critical water level 209 constitutes the first water storage area 211. The cache chamber 204 constitutes a second water storage area 212, and the highest liquid level of the cache chamber 204 is equal to or higher than the lower end surface of the rear blocking portion 107. In this way, when the cache chamber 204 is full of water, there is no gap between the rear blocking portion 107 and the water in the cache chamber 204, which can prevent external air from entering the inner chamber 101, inhibit the growth of bacteria in the inner chamber 101, and make the water output from the water vapor separation body cleaner and more hygienic.

[0079] In a possible implementation, the inner tube 202 includes an inlet section 213 and an outlet section 214, the inlet of the inlet section 213 is connected to the first water outlet 104, the outlet of the inlet section 213 is connected to the inlet of the outlet section 214, the outlet of the outlet section 214 is located near the outlet of the sewer channel 203, and the first critical water level 209 is located on the inlet section 213. The inlet section 213 of the inner tube 202 is provided with a guide channel 215 and an exhaust channel 216, the guide channel 215 connects the first water outlet 104 and the outlet section 214, and the exhaust channel 216 connects the guide channel 215 and the sewer channel 203. The inlet section 213 can be a curved pipe, and the outlet section 214 can be a straight pipe or a curved pipe. Figure 5As shown, the water inlet section 213 is an S-shaped curved pipe, and the water outlet section 214 is a straight pipe. The water inlet section 213 lies horizontally on the upper end of the outer tube 201, and the water outlet section 214 is vertically arranged in the outer tube 201, and is positioned at the center of the cross section of the water channel 203 by the limiting rib 208. The outlet of the water inlet section 213 is provided with an internal thread, and the inlet of the water outlet section 214 is provided with an external thread, and the water inlet section 213 is threadedly connected with the water outlet section 214. Of course, the water inlet section 213 and the water outlet section 214 can be connected after being formed separately, or they can be directly formed as one piece.

[0080] Please continue to see Figure 3 , Figure 5 The first water outlet 104 is provided with a water guide pipe 108 protruding out of the box body 100; the exhaust channel 216 is in the same direction as the flow guide channel 215, the water guide pipe 108 is interference fit with the inner wall of the inlet end of the flow guide channel 215, the outlet end of the flow guide channel 215 is connected to the water outlet section 214 of the inner tube 202, and the inlet and outlet of the exhaust channel 216 are connected to the sewer channel 203. The inlet of the exhaust channel 216 is higher than the lower end surface of the water guide pipe 108, and the outlet of the exhaust channel 216 is lower than the inlet of the water outlet section 214.

[0081] The water inlet section 213 of the inner tube 202 can be integrally formed or composed of two separate parts. The water inlet section 213 is a separate part, which is convenient for production and installation. The water inlet section 213 is composed of two parts, and a gap 223 can be set on the flow channel. When the liquid flows through the flow channel, gas can be discharged from the gap 223, which is convenient for gas to be discharged from the outlet of the water channel 203.

[0082] exist Figure 8-Figure 10 In the structure shown, the water inlet section 213 is formed by the first half pipe 217 and the second half pipe 218 being connected. The first half pipe 217 is provided with a first guide groove 219 and an air guide groove 220. The second half pipe 218 is provided with a second guide groove 221 and a guide rib 222. The guide rib 222 enters the air guide groove 220 and is sealed and connected to the air guide groove 220. The first guide groove 219 and the second guide groove 221 form a guide channel 215. The water inlet section 213 also includes a gap 223, which is connected to the guide channel 215. When water passes through the guide channel 215, the gas is squeezed into the gap 223 and discharged through the gap at the bottom of the water inlet section 213. The gap 223 constitutes the above-mentioned exhaust channel 216. The gap 223 is formed by the first half pipe 217 and the second half pipe 218 being connected.

[0083] The slit 223 is arranged along the flow guiding channel 215, extending from the inlet side to the outlet side of the flow guiding channel 215, and the slit 223 has slit openings at both the inlet side and the outlet side of the flow guiding channel 215. When the water inlet section 213 is connected to the water guiding pipe 108 and the water outlet section 214, at least one of the slit openings at the inlet side and the outlet side of the flow guiding channel 215 is not blocked, so that the gas can be discharged from the slit opening through the slit 223. In a possible implementation, as Figure 5 As shown, when the water inlet section 213 is connected to the water conduit 108 and the water outlet section 214 , the gap 223 at the outlet side of the guide channel 215 is not blocked, and the gas can be discharged from the gap opening at the outlet side of the guide channel 215 .

[0084] See also Figure 3 A water collection area 109 is provided on one side of the inner chamber 101 away from the water outlet, and the water inlet 103 is located between the water collection area 109 and the water outlet. The convergence structure is docked with the water inlet 103, and is used to gather the water transported by the water inlet pipe 300 in the water collection area 109. The convergence structure includes a water retaining part and a water guiding part. The water retaining part is located between the water inlet 103 and the water outlet, and is used to prevent the water transported by the water inlet pipe 300 from flowing directly to the water outlet. The water guiding part is located between the water collection area 109 and the water retaining part, and is used to guide the water transported by the water inlet pipe 300 to the water collection area 109. The water retaining part can prevent water from splashing, and prevent the water flow from intermittently flowing to the water outlet before it is gathered, resulting in discontinuous water discharge. The water guiding part makes the water gather to one place first and then flow downward. At this time, the water flow converges, the water volume is large, and it is easy to form a siphon effect, forming a continuous water flow.

[0085] See also Figure 1-2 The box body 100 includes a lower box body 110 and an upper box cover 111. The upper box cover 111 is arranged at the top opening of the lower box body 110. The water inlet 103 and the water outlet are arranged on the bottom surface of the lower box body 110. The exhaust port 102 is arranged on the upper box cover 111. When water is heated, a large amount of steam will be generated. In the existing water vapor separation body, due to some defects in the water vapor separation, water and steam flow out from the water outlet together, causing the phenomenon of steam spraying. In order to improve this disadvantage, the present embodiment provides an exhaust port 102 and a convergence structure on the upper part of the water vapor separation body. When the high-temperature water rises to the inner chamber 101, it touches the convergence structure and is dispersed, which is convenient for gas-liquid separation. The separated steam will move to the upper part of the inner chamber 101 due to its low density and be discharged from the upper exhaust port 102. At the same time, by enlarging the space of the cavity, the air pressure of the inner chamber 101 is reduced, and the steam is prevented from flowing downward together with the water flow.

[0086] In a possible implementation, the convergence structure includes an overflow sleeve disposed on the lower box body 110 or the upper box cover 111, the overflow sleeve protrudes toward the inner chamber 101 and docks with the water inlet 103, the overflow sleeve has a front wall close to the water collection area 109 and a rear wall close to the water outlet, the front wall is provided with a water guide, the rear wall constitutes a water retaining portion, and the rear wall is higher than the water guide. The water guide may be a hole or a notch disposed on the front wall. Taking the overflow sleeve disposed on the lower box body 110 as an example, the lower end of the overflow pipe is connected to the water inlet 103, and the upper end face of the overflow pipe is inclined downward from the side close to the water outlet to the side close to the water collection area 109, so that there is a gap between the front wall of the overflow pipe and the upper box cover 111, and the rear wall of the overflow pipe is higher than the front wall, and the water entering from the water inlet 103 is blocked by the rear wall of the overflow pipe and will not flow directly to the water outlet, but will flow over the lower front wall to the water collection area 109.

[0087] In another possible implementation, the convergence structure includes a sleeve 112 disposed on the lower box body 110 and a stopper 113 disposed on the upper box cover 111, the sleeve 112 is disposed at the water inlet 103, the lower end of the sleeve 112 is connected to the water inlet pipe 300, and the upper end enters the stopper 113, the side of the sleeve 112 close to the water outlet and the side of the stopper 113 close to the water outlet are closely attached to form a water retaining part, the side of the stopper 113 close to the water collection area 109 and the side of the sleeve 112 close to the water collection area 109 are staggered to form a notch 114, the sleeve 112 is connected to the water collection area 109 through the notch 114, and the notch 114 constitutes a water guide part. The stopper 113 can be a hollow tube or a partition matched with the side wall of the lower box body 110.

[0088] like Figure 4 As shown, the water outlet is at the lowest point of the inner chamber 101, the bottom surface of the inner chamber 101, i.e., the inner bottom surface of the lower box body 110, is inclined from the water collection area 109 to the water outlet, the water inlet 103 is higher than the water outlet, and a slope and a drop are formed between the water inlet 103 and the water outlet, which increases the potential energy of the water flow, so that the water flow automatically flows to the water outlet, and at the same time, water accumulation in the inner chamber 101 can be avoided. The second water outlet 105 is arranged at one end of the bottom surface of the box body 100 away from the water inlet 103, and the first water outlet 104 is located between the first water outlet 104 and the water inlet 103. Figure 4 In the structure shown, the first water outlet 104 and the second water outlet 105 are at the same horizontal plane, but in other embodiments, since the water flow will automatically flow downward after crossing the first baffle 106, the second water outlet 105 only needs to be lower than the highest position of the first baffle 106.

[0089] In order to further increase the convergence effect of water flow and control the speed and direction of water flow, a water guide groove 115 and two retaining walls 116 are further provided on the bottom surface of the inner chamber 101. The water guide groove 115 is inclined from the water collection area 109 to the water outlet, and the first water outlet 104 is located on the water guide groove 115. The water flow out of the water collection area 109 can directly enter the first water outlet 104 along the water guide groove 115. Specifically, the cross-section of the water guide groove 115 can be V-shaped or U-shaped. The two retaining walls 116 are symmetrical along the water guide groove 115, and the distance between the two retaining walls 116 gradually decreases from the water inlet 103 to the water outlet; the setting of the retaining wall 116 narrows the water flow channel, which is conducive to accelerating the water flow speed and forming a fixed and smooth waterway. Please refer to Figure 6 The ends of the two baffles 116 near the water inlet 103 are connected to the two side walls of the lower box body 110 respectively, and are used to gather the water flowing out of the water collection area 109 in the area between the two baffles 116. Near the first water outlet 104, a triangular area is formed between the two baffles 116, the first baffle 106 and the bottom surface of the inclined inner chamber 101. The triangular area plays the role of gathering water flow. The water flow converges here, and the water level at the first water outlet 104 rises rapidly, which can quickly form the liquid level difference required for siphoning, so that the water outflow from the inner tube 202 is continuous and smooth. Please continue to see Figure 6 A transverse rib 117 is also provided at the first water outlet 104. The transverse rib 117 extends along the water guide groove 115, intercepting the water flow horizontally to prevent the water flow from forming a vortex in the triangular area.

[0090] This embodiment provides a water dispenser. Fig.12 The water dispenser includes a heating tube 400 and a water vapor separation body, and the heating tube 400 is connected to the water inlet 103 of the water vapor separation body through a sealing ring. Please refer to the above embodiment for the specific structure of the water vapor separation body, which will not be repeated here. Different from the previous structure of using a silicone hose to connect the heating tube 400 and the water vapor separation body, in this embodiment, the boiled water of the heating tube 400 directly flows into the inner chamber 101 of the water vapor separation body, so that the outlet water temperature is not lower than 98°C, which can meet the user's demand for high-temperature water.

[0091] When the user takes high-temperature water, the water boils in the heating tube 400, and the boiling water will splash directly from the heating tube 400 into the water vapor separation body. At the same time, since the instantaneous amount of water heated by the heating tube 400 is small, the water output will be intermittent and the water shape will be erratic. In response to these problems, this embodiment improves the structure of the water inlet side, the water outlet side, and the water inlet and outlet sides of the water vapor separation body to ensure continuous and stable water output. Specifically: (1) A convergence structure is designed at the water inlet 103 of the water vapor separation body to provide a flow channel for the boiling water to rise, and further converge the boiling water in the water collection area 109 to form a convergent water flow, thereby preventing the boiling water from directly splashing onto the water vapor separation body and dispersing to the water outlet, resulting in discontinuous water output. (2) The first critical water level 209 of the inner tube 202 is set higher than the first water outlet 104 to construct the conditions required for siphoning. The water in the inner chamber 101 is continuously discharged by using the siphon principle, and continuous water discharge can be formed even when taking high-temperature water of 98°C. (3) A slope is set between the water inlet 103 and the water outlet of the inner chamber 101, and two retaining walls 116 are designed in the cavity to control the direction of water flow and narrow the water flow channel to speed up the water flow, which is conducive to forming a fixed and smooth waterway.

[0092] When water extraction is finished, the heating tube 400 no longer works, the water cannot fill the entire water outlet pipe 200, and the siphon effect no longer occurs. At this time, a small amount of water cannot flow out of the first water storage area 211 and the second water storage area 212 in the water outlet pipe 200. The water in the first water storage area 211 blocks the air from entering the inner chamber 101 from the first flow channel, and the water in the second water storage area 212 blocks the air from entering the inner chamber 101 from the second flow channel. The passage between the water outlet pipe 200 and the inner chamber 101 is blocked by water, thereby inhibiting the growth of bacteria and making the water outlet of the water vapor separation body cleaner and more hygienic.
