Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an external water injection system suitable for draining remaining hot water in a bathtub to the outside, particularly a fully automatic washing machine, and a water injection method thereof.

(Prior Art) Until now, the remaining hot water in the bathtub of a bathing device has been utilized for washing, and for this purpose, a water injection mechanism has been provided in the bathing device to perform water injection. As such, for example, a hot water circulation pipe that connects a water heater with a built-in forced circulation means and a bathtub may be provided with a flow path switching means, and a water injection remote control for switching and operating this flow path switching means may be used. There are some that have.

In this device, a water injection remote control is operated to switch the flow path and set the water injection time, and the forced circulation means of the water heater is activated to inject water into the washing machine.

(Problem to be Solved by the Invention) However, with the above-mentioned device, the remaining hot water in the bathtub is simply injected into the washing machine, and the amount of water injected into the washing machine is controlled by a time setting such as a timer. ,Also,
Because the flow rate changes depending on piping conditions, voltage fluctuations applied to the pump, etc., it may not match the allowable water injection amount of the washing machine, resulting in, for example, overflowing or insufficient water.

Therefore, it is not suitable for a fully automatic washing machine that automatically performs washing, rinsing, spin-drying, and other operating procedures even if a sufficient amount of washing water is injected by a water level switch or the like.

Moreover, since the remaining hot water is simply injected into the washing machine, if the remaining hot water cools down, the washing effect will decrease, and if the amount of water injected is insufficient, it will be necessary to refill the washing machine. There is. Furthermore, since the amount of water injected may overflow, the effect of providing a water injecting mechanism will be limited, especially in fully automatic washing machines that require monitoring.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an external water injection system and a water injection method thereof that are easy to operate and suitable for washing machines, particularly fully automatic washing machines.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a bath device in which a water heater equipped with forced circulation means and a bathtub are connected and connected by a hot water circulation vibrator consisting of an outgoing pipe and a return pipe. , an external water injection mechanism is interposed in the outgoing pipe, and the external water injection mechanism pumps an amount corresponding to the amount of hot water that can be supplied to the external water injection point.
By setting the unit as a unit, there is a water pouring frequency setting means that sets in advance the number of times hot water should be poured to an external water pouring point, a different water pouring procedure selection means, and a temperature detecting means for directing hot water from the water heater to the bathtub. a flow path switching valve formed by selectively switching between a supply flow path and a flow path for supplying water to an external water injection point via a temperature detection means and a flow rate detection means; The flow rate detection means detects the temperature of hot water flowing from the hot water source, and switches and operates the flow path switching valve based on the temperature of the hot water.
The amount of molten metal poured corresponding to an external water injection point is counted as one unit, and molten metal is poured until the count value by the flow rate detection means reaches the set value of the number of times of pouring setting means.

Further, the external water injection system according to the present invention is applied to a fully automatic washing machine.

Furthermore, the external water pouring mechanism of the present invention has two steps: 1. pouring the remaining hot water in the bathtub directly into the external water pouring point; 1. heating the remaining hot water and pouring it; and 1. pouring cold water directly. A procedure for heating cold water and pouring hot water is selectively executed.

Furthermore, in the case where the procedure of heating and pouring cold water or remaining hot water is selected, the temperature of the hot water to be poured is monitored after the start of operation, and if the hot water is in a cold state or low temperature,
When the hot water is returned to the bathtub and reaches the desired temperature, it is supplied to the external water injection point via the flow rate detection means. At this time, the flow rate detection means measures the amount of hot water corresponding to the external water injection point in units The number of pouring times is counted, and pouring is continued until this count value matches a preset number of pouring times.

(Function) The external water pouring mechanism of the present invention: ■ Pouring the remaining hot water as is, ■ heating the remaining hot water and pouring it, ■
You can select and operate different pouring procedures, such as pouring cold water as it is, or heating cold water and pouring hot water, so if the washing machine has an external water pouring point, it can be operated according to the condition of the laundry. Therefore, it is possible to supply residual hot water, cold water, etc. to the washing machine at a sufficient temperature to exert the washing effect.

For example, when a selective operation command is issued for ■heating remaining hot water and pouring hot water, and ■heating cold water and pouring hot water, the remaining hot water or cold water is heated by the water heater, and the forced circulation means is activated. When the hot water flows into the flow path switching valve via the incoming pipe and the temperature detecting means of the external water injection mechanism, the temperature of the hot water at that time is detected by the temperature detecting means. If the water temperature at that time is low and the water is still cold, the flow path in the flow path switching valve is switched to the bathtub and the water is returned to the bathtub. The path switching valve is configured to switch the flow path so that the flow path is supplied to the washing machine via the flow rate detection means.

The amount of hot water supplied to the washing machine is counted by a flow rate detection means, with the amount corresponding to the washing machine being counted as one unit,
Molten metal is poured until this count value reaches a preset number of times of pouring. Note that the number of hot water pours refers to the number of times the washing machine washes with hot water, excluding the "washing" that is performed several times in the operating procedure of the washing machine, and is executed after the number of hot water pours has been exceeded. At the time of "washing", the remaining hot water or cold water is supplied to wash the clothes.

In this way, the flow rate detection means counts the amount of hot water supplied to the washing machine with a predetermined amount of hot water as one star, and continues pouring water until this count value matches the preset number of pouring times. Therefore, in a fully automatic washing machine, hot water can be reliably poured in accordance with the "washing" operation procedure of the washing machine. Therefore, the external water pouring system according to the present invention can be fully automatic. It can be applied to type washing machines.

(Example) Next, an example of a laundry hot water pouring system for carrying out the external water pouring system and the water pouring method according to the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 indicates a laundry hot water pouring system which is an external water pouring system, and this laundry hot water pouring system 1 has a bath device 2 attached with a water pouring remote control 3 which is an external water pouring mechanism.

The bath device 2 has a bathtub 4 and a water heater 5 having a circulation pump connected by a hot water circulation vibro, and the hot water circulation vibro consists of an outgoing pipe 7 and a return pipe 8.

The water injection remote control 3 is interposed in the outgoing pipe 7 and is installed near the washing machine 9 to which hot water is supplied. That is, as shown in FIG. 2, the water injection remote controller 3 sets the amount corresponding to the washing machine 9 as one unit, so that
It has a pouring frequency setting button IO for setting in advance the number of times (1 to 3) hot water should be poured into the washing machine 9, and various water pouring procedure selection buttons 11. As shown in FIG. 1, a flow path switching valve 12 is built in, and a flow path for supplying hot water from the water heater 5 to the bathtub 4 via a temperature detection means, that is, a thermistor 13, and the thermistor 13 and flow rate detection means. The temperature of the hot water from the water heater 5 is detected by the thermistor 3, and the temperature of the hot water is determined by selectively changing the flow path that supplies the washing machine 9 to the washing machine 9 via the flow rate sensor] 4. Based on this, the flow path switching valve 12 is switched and operated, and the flow rate sensor 14 is used to set a predetermined amount of hot water (for example, 15
Q) is counted as one unit, and the melt is poured until the count value reaches the number of times of pouring preset by the number of times of pouring setting button 1o. Note that the predetermined amount of hot water refers to the amount of hot water that corresponds to the amount of hot water that can be supplied to the washing machine 9.

The water injection remote control 3 and the water heater 5 are electrically connected to a controller 15 built into the water heater 5, and various operations are performed by operating the water injection procedure selection button 11 of the water injection remote control 3. There is. That is, the contents of the water pouring procedure include: ■ pouring the remaining hot water as is, ■ heating the remaining hot water and pouring it, ■ pouring cold water as it is, ■ heating the cold water and pouring it, and furthermore, the degree of heating, In other words, it is possible to select "hot" or "warm".

The washing machine 9 is a fully automatic type, and has a solenoid valve at the spout]6
A water level switch 17 is provided to detect the level of poured water or hot water. The fully automatic type may be one that automatically executes operations such as pouring hot water, washing, rinsing, and spin-drying, and may have any other operation procedures.

The external water pouring system and the washing hot water pouring system 1 for carrying out the water pouring method according to the present invention are constructed as described above, and the operation thereof will be explained next.

First, after starting the washing hot water pouring system l, press the water pouring procedure selection button 11 to: ■ pour the remaining hot water as is, ■ pour the remaining hot water by heating it (warm, lukewarm), ■ pour cold water as is, ■ heat the cold water. You can select the water pouring procedure: warm or lukewarm. Therefore, the laundry situation,
You can choose according to the operating procedure of your washing machine.
It can exert a washing effect. In addition, before pouring operation, set the number of pouring times (1 to 3) using the pouring frequency setting button IO.
) is specified.

For example, ■ Heat the remaining hot water and pour it (atsume, lukewarm),
and ■ When a selective operation command for heating cold water and pouring hot water (hot or lukewarm) is given, the following operations are performed.

■When the remaining hot water is heated and the hot water is selected for pouring (hot or lukewarm), the remaining hot water is returned to the reheating heat exchanger through the return pipe 8 under the operation of the circulation pump P of the water heater 5, and is heated. Through the outgoing pipe 7 and the thermistor 13 of the water injection remote control 3,
It flows into the flow path switching valve 12.

On the other hand, in the case of a selection command for heating cold water and pouring hot water (hot or lukewarm), the cold water is heated by the hot water heat exchanger,
The water flows into the flow path switching valve 12 via the atmosphere-opening hopper and the incoming pipe 7 via the thermistor 13 of the water injection remote control 3. Note that even when pouring hot water by heating the remaining hot water (heated or lukewarm), if there is no remaining hot water in the bathtub 4, it will be detected by turning off the water switch in the circulation pump, and the heat exchanger for hot water supply will be activated. Hot water is automatically refilled from the container.

In this way, when hot water flows into the flow path switching valve 12 via the thermistor 13, the temperature of the water is detected by the thermistor 13. If the water temperature at that time is low and the water is still cold, the flow path in the flow path switching valve 12 is switched to the bathtub 4 and the water is returned to the bathtub 4, and when the water reaches a predetermined temperature, Again, the flow path switching valve 12 switches and forms the flow path so that hot water is supplied to the washing machine 9 via the flow rate sensor 14.

The hot water supplied to the washing machine 9 is counted by the flow rate sensor 14 with the amount of hot water corresponding to the washing machine 9 as one unit, and the hot water is poured until this count value matches the preset number of times of pouring. will be done.

"Washing" is carried out after the number of pouring times has been exceeded.
In this case, the remaining hot water or cold water is supplied, and the washing machine 9 executes washing.

In this way, the flow rate sensor 14 counts the amount of hot water supplied to the washing machine 9 with a predetermined amount of hot water as one unit, and continues pouring water until this count value matches the preset number of pouring times. It is possible to perform hot water pouring by specifying the number of washings with hot water in response to the "washing" operation procedure of the washing machine 9. Moreover, as in the past, water pouring can be performed by operating a timer with a set water pouring time. Since it is not a procedure, it is suitable for fully automatic washing machines.

In addition, since the flow path switching valve 12 is a low voltage type,
There is no need for wiring work by electrical experts, simplifying construction and ensuring high safety.

Next, another embodiment of a washing hot water pouring system for carrying out the external water pouring system and the water pouring method according to the present invention is shown in FIG. 3, and will be described below with reference to the accompanying drawings. Components that are substantially the same as those constituting the above-mentioned actual flow side are designated by the same reference numerals, and detailed explanation thereof will be omitted.

As shown in the figure, the external water pouring mechanism 21 in this laundry hot water pouring system 20 includes a remote control unit 22 disposed near the washing machine 9 and a laundry hot water pouring unit interposed in the outgoing pipe 7 near the water heater 5. It is divided into 23 parts. The remote control operation unit 22 is provided with a hot water pouring frequency setting button 10 and various water pouring procedure selection buttons 11, and is electrically connected to the controller 15 in the water heater 5, while the washing hot water pouring unit 23 is It incorporates a flow path switching valve 12, a thermistor 13, and a flow rate sensor 14. Further, a water/hot water supply pipe 24 is installed from the washing hot water pouring unit 23 to the washing machine 9.

The washing hot water pouring system 20 having such a configuration also produces silica water similar to that of the washing hot water pouring system 1 described above, can exhibit a washing effect, and is suitable for a fully automatic washing machine.

Above, the external water injection system and its water injection method according to the present invention have been explained by referring to the laundry hot water pouring system 1 that pours hot water into a fully automatic washing machine. It is also applicable to

(Effects of the Invention) As described above, according to the present invention, operation is performed by switching the following steps: ■ pouring the remaining hot water as is, ■ heating the remaining hot water and pouring it, ■ pouring cold water as it is, and ■ heating the cold water and pouring it. Therefore, water can be injected according to various situations.

In addition, instead of the conventional water filling procedure using a timer operation with a set water filling time, the temperature of the hot water being poured is monitored and if it is low, it is returned to the bathtub, and if the water reaches the desired temperature. , the water is supplied to the external water injection point via the flow rate detection means, and at this time, the flow rate detection means counts the pouring amount corresponding to the external water injection point as one unit, and the count value becomes the setting value of the pouring number setting means. Since a water filling procedure is adopted in which hot water is poured until the washing machine reaches the desired level, it is possible to reliably pour water or hot water without excess or deficiency, making it suitable for fully automatic washing machines with various operating procedures.
