Description

Water-sealed water vapor separation box and water dispenser Technical Field

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

[0002] Household instant-heating countertop water purifiers are currently very popular in the market and are widely used in daily life. These purifiers utilize R0 reverse osmosis technology to filter tap water, rendering it potable. They also feature instant heating, using a 2200W heating tube to heat filtered water within 3 seconds. With multiple temperature settings, they offer significant convenience for daily life while ensuring healthy drinking water.

[0003] However, this type of water purifier also has some cleaning problems after long-term use, which are manifested as follows: hot water is heated in the heating body and flows to the water vapor separation box for separation of water and steam, and then flows out from the water outlet. Therefore, water stains remain in the water vapor separation box for a long time. When air enters the water vapor separation box from the water outlet, it is easy to breed bacteria over a long period of time, and users cannot clean this place.

[0004] Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a water-sealed water vapor separation box and a water dispenser, which can inhibit the growth of bacteria and ensure the health of users' drinking water.

[0006] A first aspect of the present disclosure provides a water-sealed water vapor separation box for a water dispenser, comprising a housing having an inner chamber, and provided with a water inlet and a water outlet communicating with the inner chamber.

[0007] In which, the water outlet includes a first water outlet, a first flow channel connected to the first water outlet is formed in the shell, and the first flow channel is provided with a first water storage area; water entering the inner chamber from the water inlet can flow out through the first flow channel; when the inner chamber stops supplying water to the first flow channel, the first water storage area is filled with water to block external air from entering the inner chamber from the first flow channel.

[0008] A second aspect of the present disclosure further provides a water dispenser, comprising the water vapor separation box of the first aspect.

[0009] Optionally, the water dispenser further includes a heating pipe, and the water outlet of the heating pipe is connected to the water inlet of the water vapor separation box.

[0010] The implementation of the above scheme has the following beneficial effects:

[0011] The present invention provides a first water outlet on the water outlet side of the box body, a first flow channel of the water outlet pipe being connected to the first water outlet, and a first water storage area being provided within the first flow channel, through which water in the inner chamber can flow out. When the inner chamber stops supplying water to the first flow channel, the first water storage area is filled with water, thereby preventing external air from entering the inner chamber through the first flow channel. After water withdrawal stops, the present invention blocks the first flow channel with water retained in the first water storage area, preventing external air from entering the water vapor separation chamber through the water outlet pipe, thereby suppressing bacterial growth in the inner chamber and ensuring cleaner and more hygienic water output from the water vapor separation box.

[0035] The following describes embodiments of the present invention in detail. Examples of the embodiments 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 intended only to explain the present invention and are not to be construed as limiting the present invention.

[0036] This embodiment provides a water vapor separation box that, in conjunction with a water dispenser, is used to direct water heated by a heating tube 400 for user consumption. Referring to Figures 1 and 11 , the water vapor separation box 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. An exhaust port 102 communicating with the inner chamber 101 is provided on the top surface of the box body 100. A water inlet 103 and a water outlet are provided at opposite ends of the bottom surface of the box body 100, respectively, communicating with the inner chamber 101. The water inlet pipe 300 communicates with the water inlet 103, and the water outlet pipe 200 communicates with the water outlet.

[0037] 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.

[0038] When the user takes hot water, the water in the heating tube 400 flows upward into the water vapor separation box, 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 in 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 normal-temperature water, the water level in 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 single flow, and there will be no bifurcated water flow, and the water shape is good. The setting of the converging 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, and helping to improve user experience.

[0039] Referring to Figure 5 , the outlet pipe 200 may include an outer pipe 201 and an inner pipe 202. The outer pipe 201 has a drain channel 203 and a buffer chamber 204. The inner pipe 202 is disposed within the drain channel 203. 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 near the outlet of the drain channel 203. A flow gap 205 exists between the outer wall of the inner pipe 202 and the inner wall of the drain channel 203. 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 within the drain channel 203, and the distance between the outlet of the inner pipe 202 and the outlet of the drain channel 203 is no 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, ensuring a beautiful water shape; and reducing the distance between the outlet of the inner tube 202 and the outlet of the sewer channel 203 can 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.

[0040] Specifically, the first baffle 106 has a rear blocking portion 107 near the second water outlet 105. The rear blocking portion 107 is located above or enters the buffer cavity 204. A second baffle 206 is provided between the sewer channel 203 and the buffer cavity 204. A flow opening 207 is formed between the rear blocking portion 107 and the second baffle 206. Water in the buffer cavity 204 can flow through the flow opening 207, over the second baffle 206, and into the flow gap 205.

[0041] The inner wall of the outer tube 201 is provided with a limiting structure that positions the lower portion of the inner tube 202 at the center of the cross section of the sewer channel 203. In one 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, with a flow gap defined between the inner tube 202 and the step. Water that flows over the second baffle 206 passes through the flow gap and merges with water flowing out of the inner tube 202. In another possible implementation, as shown in Figures 5-6, 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 is distributed along the long axis of the outer tube 201, with adjacent limiting ribs 208 forming a flow channel. The limiting ribs 208 abut the outer wall of the inner tube 202, allowing water that flows over the second baffle 206 to pass through the flow channel and merge with water flowing out of the inner tube 202.

[0042] Continuing with Figure 5, the lowest water level at the highest point on the inner tube 202 is the first critical water level 209, and the highest water level at the highest point 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 point on the first baffle 106 is higher than the second critical water level 210. As the water temperature at the water dispenser increases, the instantaneous amount of water heated by the heating tube 400 decreases, and a continuous and smooth water path cannot be formed when the water is discharged. This can cause the water dispenser to experience intermittent water discharge and erratic water flow when dispensing high-temperature water. To address this problem, this embodiment constructs a siphon away from the necessary structural conditions and utilizes the siphon principle to facilitate continuous water discharge. In 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. This pressure difference can cause the water at the first outlet to flow continuously downward, forming a continuous water discharge.

[0043] Continuing with Figure 5 , the first flow channel is provided with a first water reservoir 211, and the second flow channel is provided with a second water reservoir 212. When the inner chamber 101 stops supplying water to the first flow channel, the first water reservoir 211 fills 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 reservoir 212 fills with water to prevent external air from entering the inner chamber 101 from the second flow channel. The section of the inner tube 202 between the inlet and the first critical water level 209 constitutes the first water reservoir 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 out of the water vapor separation box cleaner and more hygienic.

[0044] In one possible implementation, the inner tube 202 includes an inlet section 213 and an outlet section 214. The inlet of the inlet section 213 communicates with the first water outlet 104, and the outlet of the inlet section 213 communicates with 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 diversion channel 215 and an exhaust channel 216. The diversion channel 215 connects the first water outlet 104 and the outlet section 214, and the exhaust channel 216 connects the diversion 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. As shown in Figure 5, 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 at 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 sewer 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. The water inlet section 213 and the water outlet section 214 are threadedly connected. Of course, the water inlet section 213 and the water outlet section 214 can be formed separately and then connected, or they can be directly formed as one piece.

[0045] Continuing with Figures 3 and 5 , the first water outlet 104 is provided with a water conduit 108 protruding outward from the housing 100. The exhaust channel 216 and the diversion channel 215 run in the same direction. The water conduit 108 has an interference fit with the inner wall of the inlet end of the diversion channel 215. The outlet end of the diversion channel 215 is connected to the outlet section 214 of the inner tube 202. The inlet and outlet of the exhaust channel 216 communicate with the sewer channel 203. The inlet of the exhaust channel 216 is higher than the lower end surface of the water conduit 108, and the outlet of the exhaust channel 216 is lower than the inlet of the outlet section 214.

[0046] The water inlet section 213 of the inner tube 202 can be integrally formed or comprised of two separate parts. A single part facilitates production and assembly. A two-part structure allows for a slit 223 to be provided in the flow channel. As liquid flows through the flow channel, gas can escape through the slit 223, facilitating gas discharge from the outlet of the drainage channel 203.

[0047] In the structure shown in Figures 8-10, the water inlet section 213 is composed of a first half-tube 217 and a second half-tube 218 joined together. The first half-tube 217 is provided with a first guide groove 219 and an air guide groove 220. The second half-tube 218 is provided with a second guide groove 221 and a guide rib 222. The guide rib 222 extends into and is sealed with 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 connects to the guide channel 215. When water passes through the guide channel 215, gas is expelled into the gap 223 and discharged through the gap at the bottom of the water inlet section 213. This gap 223 constitutes the aforementioned exhaust channel 216. The gap 223 is formed by the joint of the first half-tube 217 and the second half-tube 218.

[0048] The slit 223 is provided along the flow diversion channel 215, extending from the inlet side to the outlet side of the flow diversion channel 215. The slit 223 has slit openings on both the inlet and outlet sides of the flow diversion channel 215. When the water inlet section 213 is connected to the water conduit 108 and the water outlet section 214, at least one of the slit openings on the inlet side and the slit opening on the outlet side of the flow diversion channel 215 is not blocked, so that gas can be discharged from the slit opening through the slit 223. In one possible implementation, as shown in FIG5 , when the water inlet section 213 is connected to the water conduit 108 and the water outlet section 214, the slit opening on the outlet side of the flow diversion channel 215 is not blocked, and gas can be discharged from the slit opening on the outlet side of the flow diversion channel 215.

[0049] Referring to Figure 3 , a water collection area 109 is provided on the 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. A converging structure is docked with the water inlet 103 and is used to converge the water transported by the water inlet pipe 300 into the water collection area 109. The converging structure includes a water retaining portion and a water guide portion. The water retaining portion 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 guide portion is located between the water collection area 109 and the water retaining portion and is used to guide the water transported by the water inlet pipe 300 into the water collection area 109. The water retaining portion can prevent water from splashing, preventing the water from flowing intermittently toward the water outlet before converging, resulting in discontinuous water discharge. The water guide portion allows the water to converge at one point before flowing downward. At this time, the water flow converges, the water volume is large, and a siphon effect is easily formed, forming a continuous water flow.

[0050] Referring to Figures 1-2, the box body 100 includes a lower box body 110 and an upper box cover 111. The upper box cover 111 is located at the open top of the lower box body 110. The water inlet 103 and the water outlet are located on the bottom surface of the lower box body 110, and the exhaust port 102 is located on the upper box cover 111. When water is heated, a large amount of steam is generated. In existing water vapor separation boxes, due to some defects in the water vapor separation, water and steam flow out of the water outlet together, causing steam spray. To improve this problem, the present embodiment provides an exhaust port 102 and a converging structure at the top of the water vapor separation box. When the high-temperature water rises to the inner chamber 101, it hits the converging structure and is dispersed, facilitating gas-liquid separation. The separated steam, due to its lower density, moves to the upper part of the inner chamber 101 and is discharged through the upper exhaust port 102. At the same time, by increasing the space of the chamber, the air pressure in the inner chamber 101 is reduced, preventing the steam from flowing downwards mixed with the water.

[0051] In one possible implementation, the converging structure includes an overflow sleeve provided 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 near the water collection area 109 and a rear wall near the water outlet. The front wall is provided with a water guide, and the rear wall constitutes a water retaining portion, and the rear wall is higher than the water guide. The water guide can be a hole or a notch provided on the front wall. Taking the overflow sleeve provided 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 near the water outlet to the side near 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. 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.

[0052] In another possible implementation, the converging structure includes a sleeve 112 provided on the lower box body 110 and a stopper 113 provided on the upper box cover 111. The sleeve 112 is provided at the water inlet 103, with the lower end of the sleeve 112 connected to the water inlet pipe 300 and the upper end entering the stopper 113. The side of the sleeve 112 near the water outlet and the side of the stopper 113 near the water outlet are closely attached to form a water retaining portion. The side of the stopper 113 near the water collection area 109 and the side of the sleeve 112 near the water collection area 109 are offset to form a notch 114. The sleeve 112 is connected to the water collection area 109 through the notch 114, and the notch 114 forms a water guide portion. The stopper 113 can be a hollow tube or a partition that cooperates with the side wall of the lower box body 110.

[0053] As shown in FIG4 , the water outlet is located 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, slopes from the water collection area 109 toward 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, causing the water flow to automatically flow toward the water outlet, while also preventing water accumulation in the inner chamber 101. The second water outlet 105 is located at the 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. In the structure shown in FIG4 , the first water outlet 104 and the second water outlet 105 are at the same horizontal plane. However, 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.

[0054] In order to further enhance 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 walls 116 narrows the water flow channel, which is conducive to accelerating the water flow speed and forming a fixed and smooth waterway. Referring to Figure 6 , the ends of the two retaining walls 116 near the water inlet 103 are connected to the two side walls of the lower box body 110 , respectively, to converge the water flowing out of the water collection area 109 in the area between the two retaining walls 116 . Near the first water outlet 104 , a triangular area is formed between the two retaining walls 116 , the first baffle 106 , and the bottom surface of the inclined inner chamber 101 . This triangular area serves to converge the water flow. As the water flow converges here, the water level at the first water outlet 104 rises rapidly, quickly forming the liquid level difference required for siphoning and ensuring continuous and smooth water discharge from the inner tube 202 . Continuing to refer to Figure 6 , the first water outlet 104 is also provided with a transverse rib 117 , which extends along the water guide trough 115 , cutting off the water flow horizontally and preventing the water flow from forming vortices in the triangular area.

[0055] This embodiment provides a water dispenser. As shown in FIG12 , the water dispenser includes a heating tube 400 and a water vapor separation box. The heating tube 400 is connected to the water inlet 103 of the water vapor separation box via a sealing ring. The specific structure of the water vapor separation box is described in the above embodiment and will not be described here. Unlike the previous structure in which a silicone hose was used to connect the heating tube 400 and the water vapor separation box, in this embodiment, the water boiled by the heating tube 400 flows directly into the inner chamber 101 of the water vapor separation box, ensuring that the outlet water temperature is not lower than 98°C, which can meet the user's demand for high-temperature water.

[0056] 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 box. 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 structure between the water inlet side and the water outlet side of the water vapor separation box to ensure continuous and stable water output. Specifically: (1) A convergence structure is designed at the water inlet 103 of the water vapor separation box 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 box and dispersing and flowing 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 create the necessary conditions for siphoning. The water in the inner chamber 101 is continuously discharged using the siphon principle, and continuous water discharge can be achieved even when taking high-temperature water at 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 accelerate the water flow speed, thereby facilitating the formation of a fixed and smooth waterway.

[0057] When water extraction is completed, the heating tube 400 no longer works, the water volume cannot fill the entire water outlet pipe 200, and the siphon effect no longer occurs. At this time, a small amount of water will be unable to 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 out of the water vapor separation box cleaner and more hygienic.
