Abstract

Abstract The system includes an arrangement for adjusting a temperature of water. A plurality of outlets (28,29) are connected to water supplied objects (30,31,33). A change-over valve (27) selects one of the outlets and supplies the water to the selected outlet. An outlet setting unit (38) determines a target outlet selected from the outlets. A temperature setting (23) unit determines a target temperature. A control unit controls (36) the change-over valve and the temperature adjusting means in accordance with the target outlet and the target temperature.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 87 words
A hot water supply system comprising: (a) means for adjusting a temperature of water; (b) a plurality of outlets connected to water supplied objects; (c) a change-over valve selecting one of the outlets and supplying the water to the selected outlet; (d) an outlet setting unit determining a target outlet selected from the outlets; (e) a temperature setting unit determining a target temperature; and (f) a control unit controlling the change-over valve and the temperature adjusting means in accordance with the target outlet and the target temperature.
Claim 2
Dependent Claim 87 words
A hot water supply system comprising: (a) means for adjusting a temperature of water; (b) a plurality of outlets connected to water supplied objects; (c) a change-over valve selecting one of the outlets and supplying the water to the selected outlet; (d) an outlet setting unit determining a target outlet selected from the outlets; (e) a temperature setting unit determining a target temperature; and (f) a control unit controlling the change-over valve and the temperature adjusting means in accordance with the target outlet and the target temperature.
Claim 3
Dependent Claim 24 words
The system of claim 1 wherein the temperature adjusting means comprises a mixing valve mixing hot water and cold water at an ajustable ratio.
Claim 4
Dependent Claim 38 words
The system of claim 1 wherein the control unit controls the temperature adjusting means and thereby varies a range of the temperature of the water in accordance with which of the outlets is selected by the change-over valve.
Claim 5
Dependent Claim 27 words
The system of claim 1 wherein the temperature setting unit varies an adjustable range of the target temperature in accordance with which of the outlets is selected.
Claim 6
Dependent Claim 40 words
The system of claim 1 wherein the control unit comprises means for predetermining different target temperatures corresponding the respective outlets, and means for controlling the temperature adjusting means on the basis of the target temperature corresponding to the selected outlet.
Claim 7
Dependent Claim 19 words
The system of claim 1 wherein the change-over valve is operative to adjust a supply rate of the water.
Claim 8
Dependent Claim 63 words
The system of claim 6 further comprising means for determining a target supply rate, means for controlling the change-over valve in accordance with the target supply rate, means for detecting an actual supplied quantity of the water, means for determining a target supplied quantity, and means for suspending a further supply of the water when the actual supplied quantity reaches the target quantity.
Claim 9
Dependent Claim 33 words
The system of claim 1 further comprising a temperature safety valve which prevents a supply of the water via one of the outlets when a temperature of the water exceeds a preset temperature.
Claim 10
Dependent Claim 35 words
The system of claim 1 further comprising a remote control setting unit allowing the change-over valve to select predetermined one of the outlets and thereby performing a supply of the water via the selected outlet.
Claim 11
Dependent Claim 20 words
The system of claim 1 wherein the outlet setting unit comprises sections whose number equals the number of the outlets.
Claim 12
Dependent Claim 31 words
The system of claim 1 further comprising an end section, and passages connecting the respective outlets to the end section, the passages meeting at a point upstream of the end section.
Claim 13
Dependent Claim 54 words
The system of claim 1 further comprising means for detecting a temperature of the water, means for determining different target temperatures corresponding to the respective outlets, and means for, when the detected temperature appreciably differs from the target temperature corresponding to the selected outlet, forcing the change-over valve to select another of the outlets.
Claim 14
Dependent Claim 82 words
A hot water supply system comprising: (a) a plurality of outlets; (b) means for selecting one of the outlet and directing water toward the selected outlet; (c) means for determining a target temperature of the water; (d) means for controlling an actual temperature of the water in accordance with the target temperature; (e) means for determining a range within which the target temperature is variable; and (f) means for varying the temperature range in accordance with which of the outlets is selected.
Claim 15
Dependent Claim 82 words
A hot water supply system comprising: (a) a plurality of outlets; (b) means for selecting one of the outlet and directing water toward the selected outlet; (c) means for determining a target temperature of the water; (d) means for controlling an actual temperature of the water in accordance with the target temperature; (e) means for determining a range within which the target temperature is variable; and (f) means for varying the temperature range in accordance with which of the outlets is selected.
