Abstract

PURPOSE:To provide a hot water supply with a quick response through an operation control by remote control by making provisions for a D/C voltage output control section that controls the operation of a pressurizing pump and a remote controller that controls the operation of mixing valve, pressurizing pump and water shut-off valve. CONSTITUTION:When a hot water supply switch 68 on a remote controller 6 is operated in order to supply hot water, its signal is simultaneously transmitted to both shut-off valve control section 701 and flow rate comparing section 704 in a control unit 7, which causes a shut-off valve 4 to open and a pump control section 702 to start the pressurizing pump 3 to deliver hot water. The operation speed of the pressurizing pump 3 is controlled by the D/C output from the pump control section 702 so that the supply rate as set by a flow rate adjusting switch 64 may be attained. Meanwhile, the hot water temperature set value by a hot water temperature adjusting switch 61 on the remote controller 6 is inputted to the hot water temperature comparing section 705 in the control unit 7 where it is compared with the hot water temperature detected signal from a hot water temperature sensor 18. Based on its results, the mixing valve control section 703 causes a mixing valve unit 2 to be operated to adjust the hot water temperature.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an automatic bath water supply system using a remote control device.

Conventional technology Part 2 - In general, hot water supply to a bath starts with pouring hot water into the bathtub when taking a bath, and then manually turning on the hot water mixer while checking the amount of hot water, such as when taking a shower or taking a short bath. ing.

FIGS. 4 and 6 are a diagram of a conventional hot water supply piping system for a bathroom and an external perspective view of related equipment. 101 is a heating source device, and a water stop valve 102. A water supply pipe 104 with a pressure reducing valve 103 connected thereto is connected to the lower part. The other branch of the water supply pipe is connected to a hot water mixing faucet 10B in the bathroom.

On the other hand, the hot water supply pipe 106 is connected to the air vent valve 1o7 from the top of the device 101. It is connected to the safety valve 10B and also to the hot water mixing faucet 105. Hot water mixing faucet 10
5 can selectively use either the shower 109 or the faucet 110 by switching the internal hot water channel. In other words, the hot water mixer faucet 105 is connected to the water supply knob 111. By adjusting the degree of opening and closing of the hot water supply knob 112 and operating the switching knob 113, you can pour hot water into the bathtub 114 from the faucet 110, pour hot water into the bathtub 114, or take a shower 3t.-/106. It can be used differently.

Reference numeral 115 denotes a hot water supply pressure pump, which is installed when the hot water supply pressure is low and high pressure is required, such as when using a shower on the second floor or when using a pine surge shower.

Problems to be Solved by the Invention However, in the above configuration, the hot water supply pressure pump 11
5 is not used, hot water whose pressure has been reduced by the pressure reducing valve 103 and water are supplied to the hot and cold water mixing faucet 105, so the pressure of the mixed water dispensed from the shower 106 or faucet 110 of the hot and cold water mixing faucet 105 is 2. It was impossible to use the shower on the floor.

On the other hand, when the hot water supply pressurization pump 115 is used, the conventional hot water supply pressurization pump 115 starts and stops by detecting changes in the flow rate or water pressure in the hot water supply piping caused by opening or closing of the hot water mixing faucet 105. Therefore, due to the time lag in operation, smooth hot water supply and water stoppage were not possible, and there were problems such as pulsation occurring at low flow rates. Another problem is that because the pressure is increased only in the hot water side circuit, the pressure balance between the hot water and water fluctuates greatly, and as a result, the temperature of the mixed hot water fluctuates greatly.

The present invention solves these conventional problems, and aims to provide hot water supply with a quick response by controlling the operation using a remote control.

Means for Solving the Problems In order to solve the above problems, the bath apparatus of the present invention includes a hot water storage type water heater and a mixing valve unit that mixes hot water from the water heater and water from the water supply to a set temperature. , a DC voltage-driven pressure pump installed on the outlet side of this mixing valve unit, an electric water stop valve installed on the outlet side of this pressure pump, and a water stop valve connected to the outlet of this water stop valve in the bathroom. A hot water supply inlet unit provided, a DC voltage output control section that controls the operation of the pressurizing pump, a DC voltage output control section, the mixing valve unit, and the water cutoff valve, starting and stopping the pressure pump and the water stop valve;
This configuration includes a remote controller that can open and close the door.

Operation With the above configuration, the supply from the mixing valve unit is 6'-
/ As the pressure of hot water supplied to the sprue unit increases,
This allows for smooth hot water dispensing, water shutoff, and hot water temperature adjustment.

EXAMPLE Hereinafter, a bath apparatus which is an example of the present invention will be described with reference to the drawings.

In FIGS. 1A and 1H, 1 is a hot water storage type water heater such as an electric water heater or an oil boiler, and this water heater 1 has a safety valve 8.
．． A hot water pipe 10 having an air vent valve 9 is branched and extended to a bathroom 13, a kitchen, a washroom, and the like.

On the other hand, the water source is connected to a general water supply, and a water supply pipe 12 having a pressure reducing valve 11 is extended to the water heater 1 and the bathroom 13.

Further, the hot water pipe 10 and the water supply pipe 12 extending to the bathroom 13 are connected to a mixing valve unit 2, which is connected to a DC voltage-driven pressure pump (hereinafter referred to as pressure pump) 3. Electric valve.

Reference numeral 6 denotes a remote controller (hereinafter referred to as remote controller) provided in the bathroom 13, which controls the control section of the mixing valve unit 2, the DC voltage output control section (hereinafter referred to as pump control section) 702 and the stopper of the pressurizing pump 3. It is electrically connected at low voltage to a control unit 7 having a control for the water valve 4 .

Next, the operation section of the remote control 6 will be explained using FIG. 2.

The remote controller 6 is connected to the mixing valve unit 2 via the control unit 7. A switch section is provided for operating the pressurizing pump 3 and the water stop valve 4 and allowing the user to input conditions for hot water supplied from the hot water supply port unit 6.
