Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a shower head that sprinkles water in the shower, and in particular, the water drains quickly after the water stops. This relates to a shower head that allows quick showering.

0002

[Conventional technology]

The shower head installed in the shower equipment should be connected to a hot water mixing faucet etc. with a hose. Handheld showers that are held in your hand, and overhead type showers that are fixed to the wall of bathrooms, etc. There are fixed showers etc. Also, not only a single shower head but also a handheld shower head these days. In addition to the shower, there is a body shower, a spray shower for hair washing, and a shower for feet. There are also things called ``shower towers'' that combine showers, etc.

0003 The typical structure of the shower head installed in these shower equipment is that the main body is connected to the water supply. ・It is connected to a hot water source, and a water sprinkling plate is installed at the water spouting end of the main unit for shower water. It is something. This sprinkler plate is made with many small holes and is fed into the main body. It plays the role of discharging water and hot water in the form of thin streamlines. Also, simply In addition to watering with many thin streamlines, it also has an intermittent water spouting function. It has a surge effect and can be used by switching between water sprinkling and one concentrated water spout. There are some things.

[Problem that the idea aims to solve]

Among various types of shower heads, overhead type shower heads that are fixed to the wall are To spray water on the head and upper body, position the main body diagonally downward or use only the water spray plate. It needs to be tilted.

[0005] However, when you turn off the water after taking a shower, the remaining hot water or water gets into the shower head. It flows into the de. The flow pressure of this flowing water and hot water has already decreased. Therefore, it is difficult for the water to be ejected from the sprinkler plate, and it temporarily accumulates inside the shower head. hot water drips slowly from the sprinkler plate of the shower head over a long period of time. There is a problem that the water drains poorly.

[0006] This type of water dripping after the water has stopped is caused not only by wall-mounted shower heads but also by handheld shower heads. The same problem occurs in showers, etc. In addition, in the case of a wall-fixed type, the shower Water that drips down the body of the pad may reach the surface of the wall, causing the wall to become dirty with limescale. There are also problems such as storage.

[0007] In this way, with conventional shower heads, it takes time to drain the water after the water stops. In addition to impeding usability, it also affects the environment such as bathrooms.

[0008] The problem to be solved with this invention is to quickly drain the water from the shower head after the water stops. The purpose is to eliminate the negative effects of water dripping.

[0009]

[Means to solve the problem]

This invention connects the main body to the flow path from the water/hot water source, and supplies the water/hot water source to the water/hot water source. A shower head installed in shower equipment that has water/hot water supply and water stop functions. A check valve that opens and closes the flow path from the water supply/hot water supply source is installed near the water outlet end of the main body. The check valve contracts due to the load between the valve body and the water/hot water supply pressure, causing the valve body to close. The device is characterized by comprising a spring that biases the device in the direction.

0010

[Effect]

The check valve installed near the water discharge end of the shower head is designed to prevent water supply and hot water pressure from being applied. When the spring contracts, the valve body moves in the valve opening direction due to the water and hot water supply pressure. Ru. When the water supply/hot water supply source side is shut off, the load on the water supply/hot water supply pressure is eliminated. The spring returns to its original state and moves the valve body in the direction of closing the valve, automatically opening the flow path to the water outlet end. Close to. In this way, if the supply of water or hot water from the water supply or hot water supply source is stopped, the check valve will be activated. Water and hot water remaining in the piping after closing and shutting off the water will not flow down from the spout end. , it becomes possible to quickly drain water.

Furthermore, the valve unit 28 on the left side supplies hot water to the shower head 24 side. Supply and stop are operated by the handle 28a.

[0014] In FIG. 1, the main body 2 of the shower head 1 is the lower end of the shower head 24. By connecting the internal flow path 24a to the communication pipe 23b, the main The body 2 is communicated with this communication pipe 23b. The main body 2 is bowl-shaped with the water outlet side open. Yes, the plug 3 is fixed inside the water outlet end, leaving a slight gap 4 in the axial direction. A curved water sprinkler plate 5 is fixed integrally. This sprinkler plate 5 has a partially enlarged view in the figure. As shown, a large number of water sprinkling holes 5a are opened so that uniform shower water can be sprayed from the front. I have to.

[0015] At the back of the main body 2 there is a hole for connecting the shower head 1 to the shower head 24. A second joiner 6 is fixed through the hole 3 with its tip in the center of the plug 3. It is fitted and fixed to a. This joiner 6 has a spherical base end, and this spherical part A universal type The posture of main unit 2 can be changed to make it usable. And joiner 6 has an axial direction. A connecting channel 6a is formed in the opposite direction, and one end thereof is connected to the internal channel of the shower head 24. A check valve 8 is installed as a draining mechanism in the part of the plug 3 facing the hole 3a. I'm here.

[0016] As shown in the partially enlarged cross-sectional view of FIG. A fixed cylindrical valve seat ring 8a is seated on the inner periphery of the valve seat ring 8a, and a communication passage 6a is connected to the valve seat ring 8a. It is equipped with a valve body 8b that closes the flow path from the water outlet to the water discharge end. This valve body 8b is a valve seat A packing 8c that fits into the inner periphery of the ring 8a is provided on the outer periphery of one end, and is arranged in the axial direction. This is a protruding rod 8d. In addition, a guide block is installed at the tip of the joiner 6. The guide block 9 has a communication hole 9a formed in the guide block 9 to form a communication flow path. 6a and the water discharge end side are communicated with each other. The rod 8 of the valve body 8b is attached to the guide block 9. A guide hole 9b for slidably guiding the valve body d is opened, and the guide block 9 and the valve body are connected to each other. A spring 10 is installed between the upper end side of 8b. Spring 10 is compressed When water pressure is not applied as shown in the diagram, the valve is closed by its biasing force. The body 8d is pressed toward the seating surface of the valve seat ring 8a to close the terminal end of the communication channel 6a.

[0017] The spring constant of this spring 10 is determined by It contracts due to the flowing water pressure, and the supply from the hot water mixer faucet 20 is stopped and the communication flow path is simply closed. If the fluid pressure is not applied when it is accumulated to the inside of 6a, it will be restored to its original state. do. FIG. 4 is a schematic diagram simply showing the movement of the valve body 8b, and shows the valve unit in FIG. If the valve of the knit 27 is closed and hot water or water remains accumulated up to the communication channel 6a, As shown in (a) of the same figure, since the water pressure applied to the valve body 8b is small, the spring 10 Accordingly, the valve body 8b is seated on the valve seat ring 8a. Also, open the valve of the valve unit 27. When this happens, the valve element 8b is loaded with the water supply and hot water pressure from the hot and cold mixer faucet 20. The spring 10 contracts due to the load, the valve body 8b separates from the valve seat ring 8a, and water is discharged. Open the flow path to the end side.

[0018] In the above configuration, when the valve of the valve unit 27 is closed, as shown in FIG. The valve body 8b of the check valve 8 is seated on the valve seat ring 8a and closes the terminal end of the communication passage 6a. Ru. Then, when the valve of the valve unit 27 is opened, water supply and hot water pressure are applied to the valve body 8b. The spring 10 gradually contracts, and the valve body 8b moves away from the valve seat ring 8a. Leave. FIG. 5 is an enlarged sectional view of the check valve 8 portion showing the state at this time, and shows the communication hole 6. A communicates with the gap 4 on the back side of the water sprinkling plate 5 from the inside of the valve seat ring 8a through the communication hole 9a. ing. Since the inner diameter of the water sprinkling hole 5a made in the water sprinkling plate 5 is small, the water flowing in The combined water will once accumulate in the space of the gap 4 and will be properly distributed from all the water sprinkling holes 5a. Shower water is sprayed with discharge pressure.

[0019] Here, when the valve of the valve unit 27 is closed, the flow pressure applied to the valve body 8b is reduced. The spring 10 gradually returns to its original state accordingly. For this reason, the final Specifically, as shown in FIG. The flow path toward the water sprinkling plate 5 side is closed. Therefore, after shutting off the water, do not turn on or off the water supply. Since the check valve 8 closes due to the drop in hot water pressure, the flow from the communication pipe 23a to the communication flow path 6a The remaining hot water and water will not be sent out to the sprinkler plate 5 side. The operation of such check valve 8 Due to the construction, water does not drip from the sprinkling holes 5a of the sprinkling plate 5 after the water has stopped. Allows for quick draining.

[0020] As mentioned above, the time required to drain the water after the water is stopped can be shortened, especially when using overhead You can take a comfortable shower even if you fix it to the wall as a self-contained shower.

[0021] In the example, the shower head was explained as a wall-fixed shower head, but it can be used as a general handheld shower head. It goes without saying that the structure of the present invention can be incorporated into showers and other types of showers. and its effects can be achieved in the same way.

[0022]

[Effect of the idea]
