Description

Technical Field

[0001] The present invention relates to the technical field of water purification devices, and in particular to a water vapor separation box and drinking water equipment. Background Art

[0002] A water purifier is a drinking water device used to provide purified water. It is widely used in homes, offices, and public service places. There are some drinking water purifiers on the market that can produce purified water and heat purified water. In the prior art, in order to achieve the smooth release of hot water, the water outlet of the water purifier is connected to a water vapor separation box to prevent the water vapor from causing high-pressure spray at the water outlet and splashing the human body. However, in the existing water vapor separation box, water and steam are directly separated in the same cavity, and a large amount of steam is easily mixed in the water, resulting in poor water vapor separation effect; if the water outlet of the water nozzle is too small, the flow rate of normal temperature water will be too slow, and if the water outlet is too large, it will cause the hot water to float easily when it is discharged. These two problems are difficult to coordinate; in addition, when the water vapor is separated, because most of the separation boxes do not have an air inlet pipe, the internal water vapor is discharged from the top of the separation box, resulting in uneven air pressure inside the separation box, which causes the water inside the separation box to flow unsmoothly, causing the water at the water outlet to float.

[0003] Chinese utility model patent CN207428975U proposes a water vapor separation device, in which an upper cover body and a lower cover body are sealed and joined to form a water vapor separation chamber, a water inlet pipe is arranged in the lower box body, and an obliquely arranged water outlet pipe and a steam outlet pipe extend downward from the bottom of the lower box body, and the steam outlet pipe includes a cavity step portion arranged in the lower box body and a steam outlet portion connected to the step portion. Although the structure of the water vapor separation device is simple, the pipe length of the hot water outlet is insufficient, which will cause the hot water to float when it is discharged, and when the hot steam is discharged, the air pressure in the water vapor separation chamber is uneven, resulting in unstable water flow. Summary of the invention

[0004] In order to solve the problems in the above-mentioned background technology, the present invention provides a water vapor separation box and drinking water equipment, which can improve the separation effect of water and steam in the same cavity, coordinate the different requirements of warm water and hot water on the size of the water outlet, and maintain the air pressure in the separation chamber stable, so that the water outlet is smooth and does not float.

[0005] To achieve the above purpose, the technical solution provided by the present invention is as follows:

[0006] A water vapor separation box comprises a housing composed of an upper cover, a main body and a lower cover which can be detachably fixed, wherein a separation chamber which is integrally connected to separate water vapor is formed in the housing, wherein:

[0007] The upper cover is provided with an exhaust pipe connected to the separation chamber, the part of the separation chamber inside the upper cover is the exhaust chamber, and the exhaust chamber is connected to the exhaust pipe;

[0008] A main body, wherein a water inlet pipe and an air inlet pipe connected to the separation chamber are arranged on the main body, the water inlet pipe and the air outlet pipe are arranged on the same side, one end of the air inlet pipe is connected to the air outlet chamber, and the other end passes through the outside of the main body; an isolation chamber is arranged on the tube wall of the air inlet pipe in the separation chamber, the isolation chamber connects the separation chamber with the lower cover as a first water outlet, and the isolation chamber has at least one side for water in the separation chamber to flow out from the first water outlet; a second water outlet connected to the lower cover is also arranged at the bottom of the main body, and a detachable hot water pipe is arranged in the second water outlet;

[0009] The lower cover comprises a connected fusion cavity and a water outlet pipe, wherein the fusion cavity covers the first water outlet and the second water outlet, and the hot water pipe is connected to the water outlet pipe.

[0010] Compared with the prior art, the present invention supplements the intake air through the intake pipe to maintain the air pressure balance in the separation chamber after the water vapor is discharged, and by separating the first water outlet and the second water outlet, the water finally flows out from different water outlets according to the flow rate of the water inlet in the separation chamber, thereby achieving the goal of stabilizing the air pressure in the separation chamber and making the water outlet smooth without floating. In addition, a separate replaceable hot water pipe is used for hot water outlet, which is separated from the first water outlet for regional separation, and can coordinate the different requirements of warm water and hot water on the size of the water outlet.

[0011] Preferably, the isolation chamber includes a first baffle connected to the tube wall of the air inlet pipe and a second baffle for water outlet, the height of the first baffle is higher than the second baffle and lower than the main body, and a guide port is provided on the second baffle, wherein the air inlet pipe, the separation chamber and the main body are integrally formed. Based on the above scheme, the tube wall of the air inlet pipe, the first baffle and the second baffle can be combined to form an isolation chamber, and when warm water enters the separation chamber from the water inlet pipe, the warm water has a fast flow rate and a large amount of water, and the warm water can directly enter the second water outlet through the guide port of the second baffle, meeting the requirement of large warm water output.

[0012] Specifically, the bottom height of the main body decreases from the water inlet pipe and the isolation chamber to the second water outlet, and at least two first guide plates are integrally arranged on the inner wall of the main body, and the first guide plates, the air inlet pipe and the isolation chamber form a buffer flow channel. The hot water flowing into the separation chamber through the water inlet pipe can reduce the water flow speed in the separation chamber after flowing through the buffer flow channel, and reduce the sluggish water flow and fluttering. Since the second water outlet is at the lowest position in the separation chamber, the water will gather here.

[0013] Furthermore, second guide plates are symmetrically arranged on both sides of the second water outlet, the second guide plates are arranged on the bottom surface of the main body, one end of the second guide plates is connected to the isolation chamber, and a gap is left between the other end and the side wall of the main body, and the height of the second guide plates is lower than the isolation chamber. As for the hot water entering the separation chamber, since the water volume and flow rate are both small, it will not flow through the isolation chamber and flow out from the first water outlet, and the hot water will eventually flow out from the second water outlet through the drainage of the second guide plates.

[0014] Furthermore, the second water outlet extends outward from the main body to form a hot water conduit, and the hot water pipe is detachably accommodated and fixed in the hot water conduit. At least three clamping plates are integrally provided on the inner wall of the water outlet pipe of the lower cover to fix the hot water pipe. The hot water pipe directly enters the water outlet pipe from the second water outlet. The distance of this pipe is generally thin and long. The use of an additional hot water pipe directly replaces injection molding, which reduces the molding difficulty of the entire water vapor separation box, and is clamped and fixed by the clamping plate, so that the hot water does not float when flowing out of the hot water pipe.

[0015] Furthermore, the diameter of the first water outlet is smaller than the fusion cavity, and after the hot water pipe passes into the water outlet pipe, there is a gap between it and the inner wall of the water outlet pipe, and the radius of the water outlet pipe is more than one times that of the hot water pipe. The water outlet pipe of the lower cover serves as the final outlet for warm water or hot water, and the diameter of the water outlet pipe is more than one times that of the hot water pipe, so that the warm water flowing from the first water outlet can flow out at a larger flow rate. Although the diameter of the hot water pipe is small, it is independently set from the water outlet pipe, which can ensure that the water shape of the hot water is stable and does not float when the water is discharged.

[0016] Furthermore, the hot water pipe is made of stainless steel.

[0017] Furthermore, a slot is circumferentially provided on the lower edge of the upper cover, a clamping strip is circumferentially provided on the top of the main body, the clamping strip is engaged and fixed with the slot, a plurality of fixing columns are provided at the bottom of the main body, an internal thread is provided in the fixing column, a fixing seat corresponding to the fixing column is provided on the lower cover, and the fixing seat and the fixing column are fixedly connected by bolts.

[0018] Furthermore, the cross-section of the air inlet pipe is runway-shaped. After the air inlet pipe passes into the exhaust chamber, a gap is left between the air inlet pipe and the inner wall of the upper cover. A side of the isolation chamber adjacent to the second water outlet allows water in the separation chamber to flow out from the first water outlet.

[0019] A drinking water device comprises a device body and any one of the above-mentioned water vapor separation boxes installed in the device body.

[0020] The present invention has the following beneficial effects:

[0021] 1. When the water vapor is discharged from the separation chamber, air is added from the air inlet pipe to balance the air pressure in the separation chamber, preventing the hot steam from being ejected along with the hot water while making the water output stable and smooth;

[0022] 2. In the separation chamber, warm water and hot water will flow out from different water outlets due to their different flow rates and water volumes, and will be blocked and separated by the isolation chamber, so as to achieve the purpose of coordinating the different requirements of the two types of water on the outlet size;

[0023] 3. The hot water pipe is thin and long, and it is not easy to be injection molded together with the main body. Using a separate stainless steel pipe as a replacement can not only meet the requirements of hot water output, but also reduce the difficulty and manufacturing cost of injection molding of the main body;

[0024] 4. Multiple guide plates are arranged in the main body to buffer the hot water or warm water flowing into the separation chamber and reduce its flow rate. The diameters of the first water outlet and the second water outlet are very different, so that the hot water flowing out of the second water outlet flows more steadily and does not float due to its small diameter; the warm water flowing out of the second water outlet has a large flow rate and discharges quickly.

DETAILED DESCRIPTION

[0034] The technical solutions in the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. The components of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0035] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed connection" means that the two are connected to each other and the relative position relationship after the connection remains unchanged. It should be understood that when component A is fixedly connected to component C through component B, changes in the relative position relationship caused by the deformation of component A, component B and component C itself are allowed. "Rotational connection" means that they are connected to each other and can rotate relative to each other after the connection. "Sliding connection" means that they are connected to each other and can slide relative to each other after the connection. Among them, the two components are connected to obtain an integrated structure through an integrated molding process, which means that in the process of forming one of the two components, the component is connected to the other component, and there is no need to connect the two components together through reprocessing (such as bonding, welding, snap connection, screw connection).

[0036] The directional terms mentioned in the embodiments of the present invention, such as "upper", "lower", "side", "top", "bottom", etc., are only references to the directions of the drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0037] The term "plurality" means at least two. The term "above" includes the number itself. The term "and / or" is a description of an association relationship between associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The terms "first", "second", etc. are used only for descriptive purposes and cannot be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0038] In order to solve the problem that the existing water vapor separation effect is not good, the hot water outlet and the warm water outlet need to be set differently. Using the same caliber of the water outlet will result in inconsistent water output, unstable air pressure, obvious water shaking in the separation chamber, and unstable water output. Since the hot water pipe is generally thin and long, it is difficult to injection mold it together with the main body of the separation box. In order to facilitate manufacturing and reduce costs, the content of the present invention is specially proposed.

[0039] See also Figures 1 to 4 The present invention provides a water vapor separation box as a whole and the structure of each component. The present invention provides a water vapor separation box, including an upper cover 1, a main body 2 and a lower cover 3 fixedly formed as a shell, and a separation chamber 5 for separating water vapor is formed in the shell. In this embodiment, the bottom of the upper cover 1 is concave along the circumference to form a card groove 13, which corresponds to the card strip 29 arranged along the circumference at the top of the main body 2, and the two are plugged and fixed. The card groove 13 is also provided with a specific notch 14 for facilitating the separation of the upper cover 1 and the main body 2 through the notch 14. The main body 2 is also provided with three card blocks 210 for strengthening the plug-in stability of the upper cover 1 and the main body 2; in addition, four fixing columns 28 are integrally formed on the outer shell of the main body 2, and the fixing columns 28 are provided with internal threads. The lower cover 3 is also integrally provided with a fixing seat 34 corresponding to the fixing column 28, and the fixing seat 34 and the fixing column 28 are fastened and installed by bolts to form the shell part of the water vapor separation box.

[0040] See also Figures 5 to 7The sectional structure diagrams from different angles show that the housing is composed of an upper cover 1, a main body 2 and a lower cover 3, which form a separation chamber 5 that is connected to each other. The other concave part of the separation chamber 5 in the upper cover 1 forms an exhaust chamber 12, which is connected to an exhaust pipe 11 integrally formed on the upper cover 1, and is used to discharge the hot water vapor in the separation chamber 5, and separate water and hot steam by using the rising water vapor. In order to balance the unstable air pressure caused by the water vapor being discharged from the separation chamber 5, an air intake pipe 22 is integrally formed on the main body 2, which penetrates the separation chamber 5 from the outside of the main body 2 and directly passes into the exhaust chamber 12. A gap is left between the top of the air inlet pipe 22 and the inner wall of the exhaust chamber 12, so that the air entering the separation chamber 5 from the outside can flow smoothly, and the air temperature entering the exhaust chamber 12 is lower than the hot water vapor, so it will sink into the separation chamber 5 of the main body 2, squeezing out more hot water vapor to be discharged through the exhaust pipe 11, and supplemented by external gas, which avoids the mixing of hot water and hot steam when water comes out, and also balances the air pressure in the separation chamber 5, making the water output more stable; the cross-section of the air inlet pipe 22 is a runway shape, which has a larger size than an ordinary circle, and can quickly replenish the intake air.

[0041] See also Figure 5-8 The main body 2 is an integral injection-molded structure, and is provided with a water inlet pipe 21 for inletting water into the separation chamber 5. The water inlet pipe 21 is arranged on the same side as the exhaust pipe 11. An isolation chamber 23 is provided inside the main body 2, wherein the isolation chamber 23 is composed of a portion of the pipe wall of the intake pipe 22 and a first baffle 231 symmetrically connected to the pipe wall and a second baffle 232 for water outlet. The first baffle 231 is a slightly slow curved plate. The height of the first baffle 231 is higher than the second baffle 232 and slightly lower than the height of the main body 2. In this way, water can be guided to flow to the second baffle 232 through the first baffle 231 and the intake pipe 22, and then flow into the isolation chamber 23. The second baffle 232 is provided with The guide port 2321 is a V-shaped port, and the height of the second baffle 232 is determined by the water velocity entering the separation chamber 5. Generally, the hot water flow rate is controlled at about 450-550 ml / min, and it cannot exceed the height of the second baffle 232. The normal temperature water flow rate will be greater than 700 ml / min, and will exceed the guide port 2321 of the second baffle 232 and flow into the isolation chamber 23, and flow from the first water outlet 25 with a large diameter to the lower cover 3, and then flow out at the larger diameter of the water outlet pipe 32. By setting the isolation chamber 23, the first water outlet 25 for warm water and the second water outlet 26 for hot water can be separated, and the requirements of warm water and hot water for water outlets of different diameters can be coordinated.

[0042] See also Figure 8The axonometric cross-sectional view of the water vapor separation box is shown. In order to further stabilize the hot water flowing into the separation chamber 5, a first guide plate 24 is symmetrically arranged on the inner wall of the shell of the main body 2 with respect to the air inlet pipe 22 and the isolation chamber 23. The first guide plate 24 is arranged to extend from the bottom to the top of the main body 2, and can guide water of different depths. A second water outlet 26 is provided at the bottom of the main body 2 on one side of the second baffle 232 of the isolation chamber 23. The second water outlet 26 is the outlet of hot water, and its size requirements are thin and long. The second water outlet 26 extends downward by a short section of the pipe to form a hot water conduit 261 as a part to accommodate and stabilize the hot water pipe 4. In this embodiment, the hot water pipe 4 is a stainless steel pipe with an inner diameter of 3.2 mm, an outer diameter of 4 mm, and a length of 22 mm. It is a standard part that can be directly purchased on the market, has no production difficulty, and does not require plastic injection molding, thereby reducing the difficulty of integral injection molding of the main body 2.

[0043] The second guide plates 27 are symmetrically arranged on both sides of the second water outlet 26. The second guide plates 27 are arranged on the bottom surface of the main body 2, one end of which is connected to the second baffle plate 232 of the isolation chamber 23, and the other end of which is spaced apart from the side wall of the main body 2. The height of the second guide plates 27 is much lower than the second baffle plate 232 of the isolation chamber 23. The bottom surface height inside the main body 2 decreases from the water inlet pipe 21 and the isolation chamber 23 to the second water outlet 26 in sequence. The second guide plates 27, the air inlet pipe 22 and the isolation chamber 23 form a buffer flow channel. The hot water flowing into the separation chamber 5 through the water inlet pipe 21 can reduce the water flow velocity in the separation chamber 5 after flowing through the buffer flow channel, and reduce the sluggish water flow and fluttering. Since the second water outlet 26 is at the lowest position in the separation chamber 5, the water will gather here. Since the flow velocity of the hot water is not fast, when the hot water flows to the vicinity of the second water outlet 26, it is guided by the second guide plates 27 to flow into the hot water pipe 4 of the second water outlet 26 and flows out.

[0044] See also Figure 4 and Figure 5The lower cover 3 in this embodiment includes a fusion cavity 31 and a water outlet pipe 32, wherein three clamping plates 33 are integrally arranged on the inner wall of the water outlet pipe 32, and the hot water pipe 4 is clamped and fixed, so that the hot water pipe 4 directly passes into the water outlet pipe 32 from the second water outlet 26, and the hot water exhausted by the hot steam is directly sent out of the separation box from the separation cavity 5 by the stainless steel hot water pipe 4, so that the hot water is very stable when it comes out, and the water shape is very straight without floating. The inner diameter of the water outlet pipe 32 is larger than the outer diameter of the hot water pipe 4, and the gap between the two is used to flow out warm water, specifically After the main body 2 and the lower cover 3 are fastened, the caliber of the fusion chamber 31 covers the first water outlet 25 and the second water outlet 26, so that the warm water flowing into the isolation chamber 23 and then flowing out of the first water outlet 25 is gathered in the fusion chamber 31. The caliber of the first water outlet 25 is much larger than that of the second water outlet 26, and the warm water flowing into the separation chamber 5 has a faster flow rate and a larger water volume. Therefore, the warm water flowing into the fusion chamber 31 can flow out in large quantities from the larger gap between the water outlet pipe 32 and the hot water pipe 4, meeting the requirement of large-scale water outlet.

[0045] The present invention also provides a drinking water device, comprising a device body and a water vapor separation box installed in the device body, wherein the drinking water device comprises a water drinking machine, a water purifier, a water purifier, a direct drinking machine and other drinking water devices.
