Description

Technical Field

[0001] The utility model belongs to the technical field of water purification, and in particular relates to a water vapor separation box. Background Art

[0002] With the improvement of living standards, people have higher requirements for drinking water temperature, and heating faucets are widely used.

[0003] On the one hand, since steam is generated when water is heated, if steam and hot water flow out of a hot water outlet at the same time, it will cause unstable water outlet or steam spraying. In order to avoid this phenomenon, a water vapor separation box is usually set at the hot water outlet of the hot water pipe to separate hot water and water vapor.

[0004] On the other hand, the heating speed of the heating faucet is slow, especially for hot water, which is frequently needed by users. The heating time is long and users need to wait for a long time, resulting in poor user experience. Therefore, a hot water tank is usually installed in the water purifier to heat the water in advance and store it in the hot water tank. When the user needs it, the hot water is mixed with normal temperature water in a certain proportion to obtain the temperature required by the user.

[0005] However, in the existing heating faucets, when the user has used up the hot water, the hot water in the pipeline between the hot water outlet of the hot water pipe and the hot water tank cools down due to long-term non-use. When the user needs hot water next time, the user cannot get hot water in time. Utility Model Content

[0006] The utility model provides a water vapor separation box to solve the problem in the prior art that when a user has used up the hot water, the hot water in the pipeline between the hot water outlet of the hot water pipe and the hot water tank cools down due to long-term non-use, and the user cannot obtain hot water in time when he needs hot water next time.

[0041] In order to make the purpose, technical solution and advantages of the embodiments disclosed in the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present utility model.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. Specific embodiments

[0044] like Figure 1-Figure 5 As shown, this embodiment provides a water vapor separation box (100), comprising an upper box body (10) and a lower box body (20) stacked up and down, the upper box body (10) is covered with a top cover (11) on the top, and a water hole (14) is provided at the bottom to connect with the lower box body (20), and the lower box body (20) is provided with a water outlet (24) at the bottom.

[0045] Specifically, the upper box body (10) is provided with a hot water chamber (12) and an exhaust chamber (13) arranged around the outer periphery of the hot water chamber (12), the hot water chamber (12) is connected to a hot water pipe (15), a duckbill valve (121) is arranged in the hot water chamber (12) to communicate with the exhaust chamber (13), and the exhaust chamber (13) is provided with an exhaust hole (131) to communicate with the atmosphere. The lower box body (20) is provided with a separation chamber (21) and an exhaust passage (22), the separation chamber (21) is connected to a normal temperature water pipe (23), and a steam outlet (222) of the exhaust passage (22) is arranged at the bottom of the lower box body (20).

[0046] According to the utility model, when a user takes normal temperature water, the hot water pipe (15) is closed and the normal temperature water pipe (23) is opened, and the normal temperature water enters the separation chamber (21) along the normal temperature water pipe (23) and is discharged from the water outlet (24);

[0047] When the user takes hot water, the normal temperature water pipe (23) is closed and the hot water pipe (15) is opened. After the hot water enters the hot water chamber (12) along the hot water pipe (15), it flows into the separation chamber (21) from the water through hole (14). Under the influence of density, the water vapor in the hot water rises and is discharged from the steam exhaust channel (22), and the hot water is discharged from the water outlet (24), thereby achieving water vapor separation.

[0048] When the user has finished using the hot water, the normal temperature water pipe (23) and the hot water pipe (15) are both closed. After the hot water in the hot water chamber (12) is emptied, the hot water chamber (12) is in a negative pressure state. At this time, the external gas enters the hot water chamber (12) from the duckbill valve (121) along the exhaust chamber (13), so that the air pressure in the hot water chamber (12) reaches equilibrium with the external pressure. The hot water in the pipeline between the hot water pipe (15) and the hot water tank flows back to the hot water tank under the action of gravity for heat preservation. When the user uses hot water next time, the hot water enters the water vapor separation box (100) from the hot water tank along the hot water pipe (15) for use by the user, so that the user can use hot water at any time and reduce waiting time.

[0049] In a more preferred embodiment, the upper box body (10) is connected to an exhaust pipe (132) to communicate with the exhaust chamber (13), and the other end of the exhaust pipe (132) is connected to a hot water tank, so that when the hot water tank is replenished or heated, the gas in the hot water tank is discharged in time to ensure the pressure balance in the hot water tank.

[0050] In a more preferred embodiment, an umbrella valve (141) is provided in the water through hole (14) so ​​that the hot water in the hot water chamber (12) can flow unidirectionally to the separation chamber (21). Specifically, the umbrella valve (141) is an umbrella-shaped float. When hot water enters the hot water chamber (12) through the hot water pipe (15), the umbrella valve (141) falls under the gravity of the hot water. At this time, the water through hole (14) is connected, and the hot water flows from the water through hole (14) into the separation chamber (21); when normal temperature water enters the separation chamber (21) through the normal temperature water pipe (23), the umbrella valve (141) floats up under the buoyancy of the normal temperature water. At this time, the water through hole (14) is closed, and the normal temperature water cannot enter the hot water chamber (12), thereby realizing the unidirectional flow of water in the hot water chamber (12) and preventing the normal temperature water from entering the hot water chamber (12).

[0051] In a more preferred embodiment, the exhaust passage (22) is longitudinally arranged on the side wall of the separation chamber (21), and the height of the steam inlet (221) of the exhaust passage (22) is higher than the height of the water inlet (231) of the normal temperature water pipe (23). Specifically, when the water flow rate is small, the water level in the separation chamber (21) is lower than the height of the steam inlet (221), and the water is directly discharged from the water outlet (24); when the water flow rate is large, the separation chamber (21) is filled with water and the water level is higher than the height of the steam inlet (221). At this time, a part of the water in the separation chamber (21) is discharged from the exhaust passage (22), and merges with the water discharged from the water outlet (24) to form a large flow water column, and the water discharge is smoother.

[0052] In a more preferred embodiment, the number of exhaust channels (22) is at least 2 and they are spaced apart on the side wall of the separation chamber (21), and at least one exhaust channel (22) is provided with an overflow port (223). As shown in the figure, in this embodiment, the number of exhaust channels (22) is 4 and they are evenly distributed on the side wall of the separation chamber (21), and two exhaust channels (22) are provided with overflow ports (223). Specifically, when the water level in the separation chamber (21) is higher than the height of the overflow port (223) but lower than the height of the steam inlet (221), a portion of the water in the separation chamber (21) is discharged from the exhaust channel (22) along the overflow port (223) and merges with the water discharged from the water outlet (24), so that the water flow rate in a certain interval is smoother. It can be understood that the number of exhaust channels (22) can also be 2, 3 or more, which is subject to actual production requirements and is not limited here. More specifically, the exhaust passages (22) are evenly distributed on the side walls of the separation chamber (21) to disturb the hot water in the separation chamber (21) and help break bubbles, thereby accelerating the separation of water vapor and preventing the water vapor from interfering with the water flow shape and flow rate of the water outlet (24), making the outlet water flow more stable.

[0053] In a more preferred embodiment, a spiral spring (211) is provided in the separation chamber (21), and the diameter of the spring (211) decreases from top to bottom, and the top of the spring (211) abuts against the bottom of the upper box body (10), and the bottom abuts against the bottom of the water outlet (24). The water vapor separation box (100) is mostly made of hydrophobic plastic material, which easily causes the water flow in the separation chamber (21) to be disturbed and dispersed, thereby causing the water flow at the water outlet (24) to splash; in this embodiment, a spiral spring (211) is provided in the separation chamber (21), and the water flow entering the separation chamber (21) from the water hole (14) or the water inlet (231) gathers along the spiral direction of the spring (211) toward the water outlet (24), so that the water flow at the water outlet (24) converges into a water column. Specifically, the spring (211) is made of hydrophilic stainless steel.

[0054] In a more preferred embodiment, the bottom surface of the separation chamber (21) is smoothly recessed from the periphery to the middle, so that the water in the separation chamber (21) can flow out of the separation chamber (21) more easily.

[0055] In a more preferred embodiment, at least two arc-shaped connecting ribs (241) are radially disposed inside the water outlet (24), and the connecting ribs (241) enclose a circular hole. Water in the separation chamber (21) is discharged along the circular hole enclosed by the connecting ribs (241), and the water flow is more concentrated.

[0056] In a more preferred embodiment, a bottom cover (25) is provided at the bottom of the lower box body (20), and the connecting rib (241) is located in the circular hole (251) of the bottom cover (25), and an annular gap is left between the connecting rib (241) and the inner wall of the bottom cover (25) to form a steam outlet (222). On the one hand, the steam outlet (222) is located at the periphery of the water outlet (24), so that the water in the separation chamber (21) is discharged along the middle of the circular hole (251) and the water vapor is discharged along the periphery of the circular hole (251), that is, the water vapor will not cause disturbance to the water flow of the water outlet (24), so that the water flow is more stable; on the other hand, the bottom cover (25) is radially narrowed from top to bottom, so that the water flow discharged from the water outlet (24) is more concentrated, and the water outlet is more beautiful.

[0057] In a more preferred embodiment, a one-way valve (232) is provided in the normal temperature water pipeline (23) to prevent bacteria in the normal temperature water from entering the separation chamber (21).

[0058] The above are only specific embodiments of the present invention, so that those skilled in the art can understand or implement the present disclosure. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
