The action and the effect of hot-water thermoregulating valve 100 of the present invention will be described below.
Hot-water thermoregulating valve of the present invention can be provided by the high-temperature hot water that is provided by heat exchanger and do not have change, and can supply the moderate temperature that is mixed with high-temperature-hot-water and cold water hot water.
When using high-temperature hot water,, have no the ground of change and flow out by first hot water outlet 121 by heat exchanger inflow hot water inlet's 120 high-temperature-hot-water.The temperature of high-temperature-hot-water is control like this: microcomputer compares hot water serviceability temperature of setting and the hot water temperature who measures (by the temperature sensor measurement of installing along flow channel), go to control the supply of coal gas again, and and then control be sent to the amount of combustion gas of heat exchanger.
When using the hot water of moderate temperature, hot water that comes by the hot water inlet in the hot water service cap 109 120 and the cold water that comes by 102 cold water inlet 123 in the cold feed cap mix in main valve body 119, and pass through 122 outflows of second hot water outlet.
When opening close/open valve when using the hot water of moderate temperature, it is lower than the pressure of hot water supply cap 109 and cold feed cap 102 that the water pressure of main valve body 119 becomes.Therefore, the cold water that is included in the hot water in the hot water service cap 109 and is included in the cold feed cap 102 promotes first spool 112 and second spool 116 towards damper 108 directions, and the hole O by first disk 110 and second disk 103, enter in the main valve body 119.
Hot water and cold water mix in main valve body 119, become the hot water of relatively low moderate temperature.The hot water of this moderate temperature flows out by second hot water outlet 122.
The microcomputer (not shown) compares the hot water serviceability temperature of setting and the hot water temperature of discharge (using the temperature sensor measurement of installing along flow channel), thereby and suitably drive stepper motor 124, hot water that promptly can the centering equitemperature carries out temperature control thus, and this has just regulated the proportions of ingredients of hot water and cold water.
If the hot water temperature of flowing out is lower than the hot water serviceability temperature of setting, then hot water flow increases.If be not like this, then the cold water flow increases.
Microcomputer compares the hot water serviceability temperature with the hot water temperature of flowing out by second hot water outlet 122 (utilize along the temperature transducer of flow channel installation and measure), and drives stepper motor 124, the hot water serviceability temperature that makes the hot water temperature equal to set.This will promote damper 108 motions.
For example, if the hot water temperature is lower than the hot water serviceability temperature of setting, then stepper motor 124, lever 101 and control lever shaft S2 promote damper 108 to left movement, as shown in Figure 5.In this case, first spring 113 is promoting first piston 114 towards damper 108 motions.Simultaneously, the compressive force of damper 108 enters in the receiving hole of second spool 116 second piston 118.
In this state, when promoting first spool 112, the amount of cold water that the amount that enters the hot water of main valve body 119 enters main valve body when promoting second spool 116 is big.As a result, the moderate temperature hot water that mixes under the hot water serviceability temperature of setting is flowed out by second hot water outlet 122.
When the stepper motor 124 according to the work of microcomputer output signal promotes lever 101, when control lever shaft S2 and damper 108 move to the left or to the right, can control the hot water temperature of the moderate temperature that flows out by second hot water outlet 122.
As mentioned above, because hot-water thermoregulating valve of the present invention can be simultaneously or the hot water that supply temperature is high selectively and the hot water of moderate temperature, high-temperature-hot-water can be supplied to the part that needs high-temperature-hot-water, as shower room, and the hot water of moderate temperature can be supplied to the part that needs moderate temperature hot water, as washtub and washing machine.
In addition, for convenience's sake, the present invention can control the hot water serviceability temperature automatically, has wherein set high-temperature-hot-water and moderate temperature hot water.
