Abstract

PURPOSE:To give no cooling water shock even if a shower is taken directly in the water or intermediate period by making a mist valve at least a two-way change valve while using at least two mist valves and providing a specification different in respective spray particles. CONSTITUTION:When an origin valve of a water feeding pipe 1 and a hot water supply pipe 2 is opened, hot water is supplied to apply water feeding and hot water supply pressure to a wax thermo-mixing valve 10, a mist valve 15 and a two-valve mixing plug 17 through tees A 5, 6, filter check valves 7, 8 and a tee B 9 so as to be in a condition of water feeding and hot water supply. At this time, when a temperature regulator knob 10' of the mixing valve 10 is set at a certain temperature to rotate a water stop and flow regulation knob 10'' clockwise so as to regulate a degree of opening, a proper flow is supplied to a two-way change valve 11. At this time, the switching knob 11' is rotated in the direction of a shower 14, water is discharged to a hand shower 14. In addition, when the knob 15' of the valve 15 is rotated in the direction of a nozzle 16, a mist shower is jetted from a mist nozzle 16. On the other hand, when the knob 15' of the valve 15 is rotated in the direction of a mist nozzle 16' to open, a middle-mist shower is jetted.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a domestic system bus unit.

2. Description of the Related Art Conventionally, this type of system bath has a water outlet 3 to the bathtub, which is centered around a mechanical or wax thermo mixing valve 1 and a mechanical two-valve mixing valve 2, as shown in FIG. 2, and a two-way switching valve. Mainly, hot water is supplied to the water spout 5 to the bathroom washing area branched from 4 and the hand shower 6, and the connection between the primary water supply pipe 7 and the primary hot water supply pipe 8 is to the primary water supply side and the primary hot water supply side. The filter-equipped check valve 11.12 and the filter-equipped check valve 11.
12 are connected to the wax thermomixing valve 1, and the other is connected to the mechanical two-valve mixing valve.

Problems to be Solved by the Invention According to such conventional means, a check valve is provided at the outlet of the primary water supply and the primary hot water supply, and a check valve is installed behind the check valve to separate the bathtub and washing area or hand shower in one direction. Therefore, if the pressure on the water supply side becomes abnormally high compared to the hot water supply side, or vice versa, for example, when water is being spouted into the bathtub,
Under the former condition, if the wax thermo mixing valve is set at a certain temperature that does not close (for example, 42°C setting condition), the mixing valve is in an open state, and cold water is flowing from the water supply side to the hot water supply side. The water flowed backwards, making it impossible to supply hot water to the bathtub, and only cold water could be spewed out. Furthermore, since a check valve is installed in the water circuit before the water spout to the bathtub, there is a problem in that the amount of water spouted is suppressed. On the other hand, when taking a shower in the bathroom, the particle diameter of the spray from the shower is large, so in winter or mid-season, when the body is cold, the first spray of water from the hand shower gives a cold water shock to the body, causing discomfort. I had a challenge to give.

Means for Solving the Problems In order to solve these problems, the present invention particularly uses a mist valve as at least a two-way switching valve, uses at least two mist nozzles, and uses one nozzle as the other nozzle. Each specification is in a mist state, that is, about 25
0 micron or less, and the other one is in a medium mist state, that is, in the range of approximately 250 to 600 microns.The two nozzles can be used depending on how they are used. When water is sprayed from a shaped nozzle, the particle size is very fine, so it forms a small mist on the tip of the hair on the body surface and adheres to and covers the entire body.Therefore, the cold water spray cools the body rapidly. Therefore, heat shock does not occur; in other words, in such a state, the whole body becomes a film of mist-like spray water, which prevents heat radiation from body temperature. In this situation, even if you use a large medium-mist water shower, your body will not experience heat shock, and even if you gradually increase the amount of spray, you will not experience heat shock even if you use a hand shower. This allows you to enjoy your shower life.

EXAMPLE An example of the present invention will be described below based on the drawings. In Fig. 1, 1 is a primary water supply pipe, 2 is a primary hot water supply pipe, and 3.
4 is a hook for each water supply or hot water supply unit, 5.6
is a cheese for water supply or hot water supply (A), 7.8 is a check valve with a filter for water supply or hot water supply, 9 is a cheese branched on the water supply side (B), 10 is a mechanical wax thermo mixing valve, or an electronic mixing valve (not shown) may be used. 11 is a two-way switching valve, and the inlet side is a wax thermo mixing valve lO,
The outlet is connected to a wash area spout 12 of the bathroom, and the other is connected to the hand shower via a one-way check valve 13 of the hand shower. Reference numeral 15 is a two-way switching mist valve connected to a water supply pipe branched from the cheese (B) 9, and connects a mist nozzle 16 with a small ejected particle size and a mist nozzle 16 with a slightly larger particle size than 16. According to experiments, the appropriate diameter of the mist nozzle 16 is about 250 microns or less. 16'
is suitably about 200 to 600 microns. 17 is
The two-valve mixer faucet 18 is connected to the two-valve mixer faucet 17 at the bathtub spout of the bathroom. The solid lines in the figure indicate the water supply pipe and the hot water pipe, respectively. These pipes are constructed of water supply steel pipes or stainless steel flexible pipes set by the Japan Water Cooperation Association. In the figure, connections between mixing valves and water supply equipment are made using gaskets and pipe fitting nuts. In addition, the figure shows a state in which the bathtub spout 1 day, the wash area spout 12, and the mist nozzle 16 are differentially operated.

In the above configuration, when the main valves (not shown) of the primary water supply pipe 1 and the primary hot water supply pipe 2 are opened, water supply and hot water supply are started, and the cheese A5.6, the check valve with filter 7, 8, and the cheese B9 Water and hot water supply pressures are applied to the wax thermomixing valve 10, the mist valve 15, and the two-valve mixing faucet 17, respectively, through the water supply and hot water supply states, respectively. At this time, the temperature control knob 10' of the wax thermomixing valve 10 is set to a certain temperature (for example, 4
2℃), stop the water, turn the flow control knob 10'' clockwise to open it, and adjust the opening to supply a suitable amount of flow to the two-way switching valve 11 at a water temperature of 42℃.At this time, Switch knob 1
1'' toward the washing area spout 12 side, the water flows toward the washing area, and conversely, when turned toward the hand shower 14 direction, the washing area spout 12 stops water and water is spouted to the hand shower 14.

If the water supply knob 17° and the hot water supply knob 17' of the two-valve mixing faucet 17 are adjusted to an appropriate temperature and opening degree and opened, water is spouted into the bathtub spout 18 at will. On the other hand, open the knob 15゛ of the mist valve 15 appropriately and open the mist nozzle 1.
When turned in six directions, a mist shower is ejected from the mist nozzle 16. On the other hand, mist nozzle 16'
When the knob of the mist valve 15 is turned 15° to open the mist valve 15, a medium-mist spray shower is ejected. In addition, by switching the mist valve 15, a spray shower of m1 particles and a spray shower of medium mist are alternately ejected from the mist nozzle 16.16°, allowing you to enjoy your shower life. . During the above operation, especially when discharging water into the bathtub, even if the water pressure becomes abnormally higher than the hot water supply side due to some abnormality on the primary water supply side, the water pressure will flow backwards from the wax thermo mixing valve 10 to the two-valve mixing faucet 17 side. The water supply will not flow backwards because check valves are provided behind the wax thermomixing valve 10 on the water supply and hot water supply sides.

Incidentally, this reverse effect is unlikely, that is, the hand shower 14 and the wash area spout 12 are connected from the bathtub spout 18 side.
This is because the pressure loss of the check valves 7, 8, mixing valve 10, etc. on the side is higher than the pressure loss on the bathtub spout 18 side.

As mentioned above, by providing a plurality of mist nozzles 16.16° branching from the cheese B9 and passing through the mist valve 15, the mist nozzles 16 and 16' have a smaller particle size and are more atomized than the hand shower. In addition to switching partners alternately, the flow rate is also low, so you can enjoy a shower life during the winter and mid-season.

Effects of the Invention As is clear from the above explanation, according to the system bus of the present invention, the water supply and hot water supply pipes are connected via the cheese A between the mechanical wax thermomixing valve or the electronic mixing valve and the two-valve mixing faucet. In addition, a check valve with a filter is placed on the mechanical Wax Thermo mixing valve side, and the water supply side of the Wax Thermo mixing valve is further branched at Cheese B, and a two-way switching mist valve is installed. The following effects can be obtained by providing at least two types of nozzles: the mist nozzle 16 with an ultrafine particle size and the mist nozzle 16' with a slightly larger particle size than the mist nozzle 16.

(1) Even if some abnormality occurs in the water discharge from the bathtub and the water pressure fluctuates, and the water supply pressure becomes particularly high from the hot water supply side, it is impossible to bypass the pastaphewa 7x thermo mixing valve and supply cold water. It is now possible to comfortably discharge water into the bathtub, hand shower, or washing area spout, and to use them simultaneously.

(2) The number of check valves with filters has not increased compared to conventional ones,
No high cost due to circuit change length.

(3) A two-way switching mist valve with the water supply inlet side of the wax thermo mixing valve branched off at the cheese B, and a mist nozzle 1 for two types of spray particles with different diameters, that is, ultrafine particles.
6 and a medium mist nozzle of 16°,
You can get a mist shower with ultra-fine particles that cannot be obtained with a hand shower, and you can enjoy a comfortable shower life without causing heat shock to your body even in winter or mid-season even if you shower directly with water. Not only is it more comfortable, but sometimes you don't need a hot shower, and you only need a small amount of water.
It also saves energy. It's also healthier than a hot shower. Furthermore, it will also be useful in removing mist in the bathroom when a steam sauna or the like is installed in the future.

(4) Since the check valve that was in the water circuit before the bathtub spout was removed, the piping pressure drop was reduced, the amount of water spouted from the bathtub was increased, and the water spout time was shortened.
