Description

Technical Field

[0001] The invention relates to the field of bathrooms, and in particular to a switching component. Background Art

[0002] After the shower stops, some residual water in the pipes of the shower heads in daily households cannot be discharged. The next time you shower, the residual water will be discharged as cold water. Therefore, people are used to letting the shower head drain for a while before starting a normal shower. However, in today's homes, there is often more than one shower device, such as a shower system consisting of a common overhead shower head and a handheld shower head. The pipes of the overhead shower head and the handheld shower head are independent of each other, so the residual water in the pipes is also independent of each other. Assuming that the user drains the handheld shower head before taking a shower, when you need to switch to the overhead shower head during the shower, the overhead shower head will still discharge cold water for a period of time. Often at this time, the user will not notice the need to drain the water again, so it is easy to be sprayed with cold water, and the shower experience is relatively poor. Even if the user notices and drains the water a second time, the shower process is interrupted, and the shower experience is also poor. Summary of the invention

[0003] The main technical problem to be solved by the present invention is to provide a residual water discharge switching component. When water is discharged from one water outlet channel, the residual water in another water outlet channel is discharged; when switching to another water outlet channel for drainage, the residual water in the original water outlet channel is discharged.

[0004] In order to solve the above technical problems, the present invention provides a residual water drain switching assembly, including a main body and a switching member arranged in the main body; the main body includes a water inlet channel, a first water outlet channel, a second water outlet channel and a drainage channel;

[0006] The switching member is operated so that the water inlet is connected to one of the first water through hole and the second water through hole. At this time, the other of the first water through hole and the second water through hole is connected to the drainage channel through the drainage hole; when the water inlet is connected to the first water through hole, the water in the water inlet channel flows into the first water outlet channel through the first water through hole, and the residual water in the second water outlet channel is discharged through the drainage channel after passing through the second water through hole and the drainage hole; when the water inlet is connected to the second water through hole, the water in the water inlet channel flows into the second water outlet channel through the second water through hole, and the residual water in the first water outlet channel is discharged through the drainage channel after passing through the first water through hole and the drainage hole.

[0007] In a preferred embodiment: the switching member includes a rotating shaft, a rotating plate arranged in linkage with the rotating shaft, and a stationary plate kept stationary;

[0008] The water inlet is arranged on the rotating plate, and a concave water flow groove is provided on the lower surface of the rotating plate at a position different from the water inlet; the first water flow hole, the second water flow hole and the drainage hole are respectively arranged on the stationary plate; when the water inlet is connected with one of the first water flow hole and the second water flow hole, the water flow groove connects the other one of the first water flow hole and the second water flow hole with the drainage hole.

[0009] In a preferred embodiment: the drainage hole has a shape corresponding to the water groove on the side close to the water groove, and is a circular hole on the side away from the water groove; the circular hole is connected to the drainage channel.

[0010] In a preferred embodiment: the cross-sectional area of ​​the water channel is larger than the cross-sectional area of ​​the circular hole.

[0011] In a preferred embodiment: the first water through hole and the second water through hole are through holes with the same cross-sectional area as the circular hole.

[0012] In a preferred embodiment: the water inlet is arranged radially from the edge of the rotating piece.

[0013] In a preferred embodiment: the water inlet is always connected to at least one of the first water through hole and the second water through hole.

[0014] In a preferred embodiment: the main body includes a transverse tube, one end of which is an open end; the switching member is installed in the transverse tube along the axial direction, and the end of the rotating shaft is exposed outside the open end; an operating handle is rotatably connected to the end of the rotating shaft, and the rotating handle drives the rotating shaft to rotate.

[0015] In a preferred embodiment: the first water outlet channel and the second water outlet channel are respectively vertically arranged on the upper and lower sides of the horizontal pipe; the water inlet channel, the drainage channel and the second water outlet channel are located on the same side.

[0016] In a preferred embodiment: the first water outlet channel is connected to the overhead shower head, and the second water outlet channel is connected to the handheld shower head.

[0017] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0018] 1. The present invention provides a residual water discharge switching component, which is connected to a water hole through a water inlet to realize the water discharge function of the first water outlet channel; at the same time, another water hole is connected to the drain hole, so that when the first water outlet channel discharges water, the residual water in the second water outlet channel is discharged through the drain channel. In this way, the purpose of simultaneous drainage and water flow is achieved. When the user switches from the first water outlet channel to the second water outlet channel, hot water can flow out of the second water outlet channel immediately to prevent the user from being splashed with cold water, thereby affecting the user experience of showering. Moreover, the residual water in the first water outlet channel is also discharged by the drain channel while the second water outlet channel is flowing with water. It can ensure that the user will not be splashed with cold water while freely switching between the first water outlet channel and the second water outlet channel.

[0019] In addition, since a line of cold water is always drained after the last shower, this means that each time the user takes a shower, the cold water only needs to be drained once at most. The user does not need to form the habit of draining the cold water twice before showering, which shortens the waiting time before showering and improves the shower experience.

[0020] 2. In the residual water drain switching assembly provided by the present invention, during the rotation of the rotating shaft of the switching valve, the water inlet hole on the rotating plate always maintains communication with at least one of the first water hole and the second water hole. In this way, when the shower starts, no matter how the user performs the switching operation, at least one of the first water outlet channel and the second water outlet channel is in a water flow state. In particular, when the user uses a gas water heater, the gas water heater will not be turned off due to the water stop state during the switching process. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] refer to Figure 1-10 A residual water drain switching assembly includes a main body 1 and a switching member 2 disposed in the main body 1; the main body 1 includes a water inlet channel 11, a first water outlet channel 12, a second water outlet channel 13 and a water discharge channel 14; in this embodiment, the main body 1 includes a transverse tube, one end of which is an open end; the switching member 2 is installed in the transverse tube along the axial direction. The first water outlet channel 12 and the second water outlet channel 13 are respectively vertically disposed on the upper and lower sides of the transverse tube; the water inlet channel 11, the water discharge channel 14 and the second water outlet channel 13 are located on the same side.

[0033] In this embodiment, the first water outlet channel 12 is connected to the overhead shower, and the second water outlet channel 13 is connected to the hand shower. Other water outlet devices, such as a kitchen shower, can also be connected as needed, which is a simple replacement of this embodiment and will not be described in detail.

[0034] The switching member 2 has a water inlet 21, a first water hole 22, a second water hole 23 and a drain hole 24; wherein the water inlet 21 is connected to the water inlet channel 11, the first water hole 22 and the second water hole 23 are connected to the first water outlet channel 12 and the second water outlet channel 13 respectively, and the drain hole 24 is connected to the drain channel 14;

[0035] The switching member 2 is operated so that the water inlet 21 is connected to one of the first water hole 22 and the second water hole 23 . At this time, the other of the first water hole 22 and the second water hole 23 is connected to the drainage channel 14 through the drainage hole 24 .

[0036] Therefore, the following water outlet effect is formed: when the water inlet 21 is connected with the first water through hole 22, the water in the water inlet channel 11 flows into the first water outlet channel 12 through the first water through hole 22, and the residual water in the second water outlet channel 13 passes through the second water through hole 23 and the drainage hole 24 and is discharged through the drainage channel 14; when the water inlet 21 is connected with the second water through hole 23, the water in the water inlet channel 11 flows into the second water outlet channel 13 through the second water through hole 23, and the residual water in the first water outlet channel 12 passes through the first water through hole 22 and the drainage hole 24 and is discharged through the drainage channel 14.

[0037] Through the above design, the residual water in the second water outlet channel 13 is discharged through the drainage channel 14 while the first water outlet channel 12 is discharging water. In this way, the purpose of simultaneous drainage and water supply is achieved. When the user switches from the first water outlet channel 12 to the second water outlet channel 13, the second water outlet channel 13 can immediately flow out hot water to prevent the user from being splashed with cold water, thereby affecting the user experience of showering. Moreover, the residual water in the first water outlet channel 12 is also discharged by the drainage channel 14 while the second water outlet channel 13 is flowing water. It can ensure that the user will not be splashed with cold water while freely switching between the first water outlet channel 12 and the second water outlet channel 13.

[0038] In order to realize the above-mentioned design, the specific structure of this embodiment is as follows:

[0039] The switching member 2 includes a rotating shaft 25, a rotating plate 26 linked to the rotating shaft 25, and a stationary plate 27; the end of the rotating shaft 25 is exposed outside the opening end; an operating handle 15 is rotatably connected to the end of the rotating shaft 25, and the rotating handle 15 drives the rotating shaft 25 to rotate.

[0040] The water inlet 21 is arranged on the rotating piece 26. In this embodiment, the water inlet 21 is arranged radially from the edge of the rotating piece 26. A concave water groove 261 is arranged on the lower surface of the rotating piece 26 at a position different from the water inlet 21; the first water hole 22, the second water hole 23 and the drainage hole 24 are respectively arranged on the stationary piece 27; the drainage hole 24 is a stepped hole, and has a shape corresponding to the water groove 261 on the side close to the water groove 261, and a circular hole on the side away from the water groove 261. In addition, the cross-sectional area of ​​the water groove 261 is larger than the cross-sectional area of ​​the circular hole.

[0041] With the above design, when the water inlet 21 is connected to one of the first water hole 22 and the second water hole 23, the water groove 261 connects the other of the first water hole 22 and the second water hole 23 to the drainage hole 24. The drainage hole 24 is set as a stepped hole, and the cross-sectional area of ​​the water groove 261 is set to be larger than the cross-sectional area of ​​the circular hole, in order to ensure that the water groove 261 can connect the other of the first water hole 22 and the second water hole 23 to the drainage hole 24 as long as the rotating piece rotates a small angle, so that the water flow area when draining the residual water is relatively large, the drainage flow rate is large, and the residual water can be quickly discharged.

[0042] The first water passing hole 22 and the second water passing hole 23 are through holes having the same cross-sectional area as the circular hole.

[0043] Furthermore, the water inlet 21 is always connected to at least one of the first water hole 22 and the second water hole 23. In this way, when the shower starts, no matter how the user switches, at least one of the first water outlet channel 12 and the second water outlet channel 13 is in a water flow state. When the user uses a gas water heater, the gas water heater will not be turned off due to the water stop state during the switching process.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that any modifications, equivalent substitutions, improvements, etc. made without departing from the present invention should be included in the protection scope of the present invention.
