【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0014]
(Example 1)
FIG. 1 shows a device for pouring water into equipment according to Embodiment 1 of the present invention.
[0015]
In the figure, reference numeral 1 denotes a water injection valve for supplying water, which is connected to a water pipe of a faucet. Reference numeral 2 denotes a pouring valve for supplying hot water, which is connected to a hot water pipe of the hot water supply device 16. The pipes of water and hot water are merged downstream of the water injection valve 1 and the injection valve 2 and connected to a flow rate sensor 13 which is a flow rate detecting means. ing. Reference numeral 14 denotes a remote controller for selecting whether to supply water or hot water when washing the laundry. Reference numeral 15 denotes a control device for forcibly closing the water injection valve 1 or the water injection valve 2 that is opened when the accumulated water flow continuously supplied to the device 8 becomes equal to or more than a predetermined amount. The water injection valve 1 and the water injection valve 2 are operated based on information from the remote controller 13 and the remote controller 14. The above-described apparatus for pouring water into the apparatus of the present embodiment may be integrated into the inside of the water heater 16 to be integrated.
[0016]
The operation and action of the apparatus for pouring water into the apparatus having the above-described configuration will be described below.
[0017]
First, when water washing is selected by the remote controller 14, the water injection valve 1 is opened and the water injection valve 2 is closed. When washing is started in this state, water is supplied to the equipment 8, and the flow sensor 13 detects water flow (flow rate). After the flow rate becomes a constant flow rate (about 3 minutes in the case of a normal fully automatic washing machine), if the flow rate is no longer detected, the appliance 8 determines that the water injection for washing has been completed. Thereafter, when the flow rate is detected, it is assumed that water for rinsing is supplied, and when the flow rate is no longer detected (about 20 minutes in the case of a normal fully automatic washing machine), the rinsing is completed. The water injection valve 1 is closed assuming that the washing is completed.
[0018]
Next, when hot water washing is selected by the remote controller 14, the injection valve 2 is opened and the injection valve 1 is closed. When washing is started in this state, hot water is supplied to the equipment 8 via the water heater 16, and the flow sensor 13 detects water flow (flow rate). After the flow rate becomes a constant flow rate (about 3 minutes in the case of a normal fully automatic washing machine), if the flow rate is no longer detected, the appliance 8 determines that the water injection for washing has been completed. In general, the washing effect is higher when using lukewarm water than when using water for washing, but water is preferably used for rinsing because using hot water tends to wrinkle clothes. Therefore, it is necessary to supply water for rinsing after the completion of the water injection in the hot water washing. Thereafter, when the flow rate is detected, it is assumed that water for rinsing is supplied, and when the flow rate is no longer detected (about 20 minutes in the case of a normal fully automatic washing machine), the rinsing is completed. The water injection valve 1 is closed assuming that the washing is completed.
[0019]
Here, if the hose connected to the device 8 comes off during washing or rinsing, the water injection valve 1 is open during the washing and rinsing, and the water injection valve 2 is open during the washing with hot water. Therefore, water or hot water flows out to the floor or the like. Then, in order to detect the end of the washing and close both the water injection valve 1 and the water injection valve 2, it is necessary to stop the water flow to the device 8 for a certain period of time. In this state, either the injection valve 1 or the injection valve 2 remains open, and the outflow of water or hot water continues until the user notices. If the hose comes off at night, in the early morning, or when washing while going out, a large amount of water or hot water may leak to the floor or the like, causing damage to household goods. Also, in condominiums, etc., there is a case where water leaked into a room downstairs leads to a compensation problem.
[0020]
Therefore, in the apparatus for pouring water into the apparatus of the present embodiment, in preparation for hose disconnection at the time of washing, when the cumulative amount of water continuously passed through the apparatus 8 becomes a certain amount or more, that is, washing is performed normally. When the amount becomes equal to or more than the maximum amount that can be considered when the operation is performed, the control device 15 is provided with a function to forcibly close the water injection valve 1 or the injection valve 2 that is open at that time. Since the continuous accumulated water flow until the water injection valve 1 or the hot water valve 2 is forcibly closed is about 70 liters even if the capacity of the equipment 8 is large, water is continuously passed to the equipment 8 for 70 liters or more. Means that the possibility of hose disconnection is high. Actually, it is set to 80 liters in consideration of the error of the flow sensor 13 and the like.
[0021]
As described above, in this embodiment, even if the hose comes off during washing, the outflow of water or hot water to the floor or the like can be stopped within 80 liters, so that the user does not notice for several hours. But it can prevent the damage from continuing to spread.
[0022]

FIG. 2 shows a device for pouring water into equipment according to a second embodiment of the present invention.
[0023]
Hereinafter, the points different from the first embodiment will be mainly described. In this embodiment, in order to supply the remaining hot water 10 in the bathtub 9 to the equipment 8, the flow path switching valve 4 is connected to a flow path of the hot water supply device 12 for circulating the remaining hot water 10, and the circulation pump 11 of the hot water supply device 12 rotates. At this time, the remaining hot water 10 is supplied to the equipment 8 or returned to the bathtub 9 to switch the flow path. The remote controller 18 is provided with a switch for selecting a mode for supplying the remaining hot water 10 at the time of washing. Further, two check valves 6 are provided downstream of the water injection valves 1 and 2 until the flow path of the remaining hot water 10 is connected. Further, a filter 17 is provided in the flow path of the remaining hot water 10 to the device 8 downstream of the flow path switching valve 4. The control device 19 controls the water injection valve 1, the water injection valve 2, the flow path switching valve 4, and the circulation pump 11. The above-described apparatus for pouring water into the apparatus of the present embodiment may be integrated into the inside of the water heater 12 to be integrated.

Next, when the remaining hot water is selected by the remote controller 18, the water injection valve 1 and the water injection valve 2 are closed, and the flow path switching valve 4 is switched to supply the remaining hot water 10 to the device 8. The 12 circulation pumps 11 are rotated. When washing is started in this state, the remaining hot water 10 is supplied to the appliance 8 and the flow sensor 13 detects the flow of water (flow). After the flow rate reaches a constant flow rate (about 3 minutes in the case of a normal fully automatic washing machine), if the flow rate is not detected, the machine 8 has finished pouring water for washing or the remaining hot water 10 has run out. Is determined. From then on, since water injection is required regardless of whether the water injection for washing is continued or the water for rinsing is supplied, the flow path switching valve 4 is switched to a position for returning the remaining hot water 10 to the bathtub 9 and the circulation pump 11 is stopped, and the water injection valve 1 is opened. Then, when the flow rate is no longer detected (in the case of a normal fully automatic washing machine, the flow rate is about 20 minutes), it is assumed that the washing is completed, and the water injection valve 1 is closed.

Therefore, in this embodiment, even in the case where the remaining hot water 10 is supplied to the device 8 in the same manner as in the case of water injection and pouring, in order to prepare for the hose being disconnected during washing, the accumulated When the amount of water becomes equal to or more than the maximum amount that can be considered when washing is performed normally, the flow path switching valve 4 is forcibly switched to a position for returning the remaining hot water 10 to the bathtub 9, The circulation pump 11 is stopped. The continuous accumulated water flow until the forced stop is set to 80 liters as in the case of water injection and pouring.
[0029]
As described above, in this embodiment, even if the hose comes off during washing, the outflow of water, hot water or remaining hot water to the floor or the like can be stopped within 80 liters, so that the user does not notice for several hours. In this case, the damage can be prevented from continuing to spread.
