BACKGROUND OF THE INVENTION
INDUSTRIAL APPLICABILITY The present invention is used by being attached to a bath tub facility supplied with a water heater, particularly a gasified oil-fired water heater, and is used for washing a fully automatic washing machine or the like without heating or heating residual water or tap water in the tub. The present invention relates to a washing pouring control device for supplying to a machine.
[0002]
[Prior art]
Conventionally, it has been widely used to select residual water or tap water in a bathtub, supply it to a washing machine with or without heating, and use it for washing.
Conventionally, gas water heaters that use city gas or the like as fuel have been used as the hot water heater type that heats tap water or heats the water remaining in the bathtub to the washing machine. It is necessary to provide a passage changer for switching a suitable passage depending on whether it is water or residual water in the bathtub, whether hot water is supplied or water is supplied. And conventionally, when supplying tap water heated using a gas water heater or heated bathtub residual water to a washing machine, the hot water supply operation of the gas water heater is turned on by turning on the operation switch of the remote controller of the passage switching device. In this way, the residual water and tap water in the bathtub can be heated and water can be immediately supplied to the washing machine.
[0003]
[Problems to be solved by the invention]
However, as a water heater for supplying the hot water or the like to the washing machine, instead of a gas water heater, the oil is indirectly heated by a heater or the like, vaporized and gasified, and then burned, so-called gasified oil burning. In the case of a water heater, even if the operation of the gasified oil fired water heater is started, the heater first requires a heater preheating period for vaporizing the oil supplied into the vaporizer. After the heater preheating is completed after a lapse of minutes, the hot water supply operation can be performed for the first time, so that even if the hot water washing mode is selected, the hot water cannot be discharged immediately.
And before completion of the heater preheating, the oil is not sufficiently vaporized and is not in a gasified state that can be combusted. Therefore, when water is passed through the water heater in this state, it is mainly made of copper. Drain water is likely to be generated on the surface of the heat exchanger, and this drain water is dripped onto the aluminum die-cast vaporizer, and this vaporizer corrodes by this dripping (due to a chemical reaction between aluminum ions and copper ions). There were problems such as.
The present invention has been invented in view of the above problems, and in the case of using a gasified oil-fired water heater or the like, when hot water is supplied to a washing machine, unheated cold water is passed through the can body. Therefore, it is possible to prevent drain water from being generated or corroding the surrounding area, and supply the washing machine with peace of mind without heating or heating residual water or tap water in the bathtub. It is an object of the present invention to provide a washing pouring control device capable of performing the above.

The pipe 7a is connected to the pipe 9 so as to be supplied to the washing machine 4 without passing through the can body 1b through a bypass or the like.
[0010]
When the tap water hot water washing mode is selected by the external remote controller 2a and the operation switch is turned on, the controller 2b of the passage changer 2 uses the information from the gasified oil fired water heater 1 side to supply the gasified oil fired water. When it is determined that the water heater 1 has completed the heater preheating of the vaporizer 1a, the hot water supply operation by the gasified oil-fired water heater 1 is started and heated in the selected tap water hot water washing mode. Tap water is supplied to the washing machine 4. On the other hand, if it is determined from the information from the gasified oil fired water heater 1 side that the heater preheating of the vaporizer 1a has not been completed, the mode is changed from the tap water wash mode to the tap water wash mode, Is switched to the tap water flush mode passage to supply tap water to the washing machine 4. Similarly, when the bathtub remaining water hot water washing mode is selected by the external remote controller 2a and the operation switch is turned on, the gasified oil fired water heater 1 is informed by the information from the gasified oil fired water heater 1 side.

On the other hand, if it is determined from the information from the gasified oil fired water heater 1 side that the heater preheating of the vaporizer 1a has not been completed, the mode is changed from the bath residual water hot water washing mode to the bath residual water water washing mode. The passage is switched to the passage in the bathtub residual water washing mode, and the residual water is supplied to the washing machine 4.
The controller 2b of the passage switch 2 has the above program built therein.
[0011]
Of course, as a control program by the controller 2b of the passage switching device 2, when the tap water hot water washing mode or the bathtub residual water hot water washing mode is selected and the operation switch by the external remote controller 2a is turned on, the gasified oil The operation of the hot water heater 1 is started, and until the heater preheating of the vaporizer 1a is completed, the mode is automatically switched to the corresponding tap water washing mode or bathtub residual water washing mode, and the washing machine 4 is left with tap water or bathtub residual water. When water is supplied and the heater preheating of the vaporizer 1a is completed, it is automatically switched again to the hot water washing mode so that heated tap water or heated bathtub residual water is supplied to the washing machine 4. It is good also as a program to control. In this way, it is possible to perform a control operation closer to the laundry desired by the user.
Further, as a control program by the controller 2b of the passage switching device 2, when the tap water hot water washing mode or the bath residual water hot water washing mode is selected and the operation switch by the external remote controller 2a is turned on, the gasified oil When the heater heating of the vaporizer 1a by the water heater is started and the heater heating is completed, the hot water supply operation by the gasified oil fired water heater is started and the tap water heated to the washing machine 4 or the heated bathtub is started. It is good also as a program controlled to supply residual water.
Moreover, in the above, the can 1b provided with the heat exchanger has, as its heat exchanger, a heat exchanger that heats and heats tap water supplied from the water supply facility 5 through the pipe 6a, and a pipe from the bathtub 3. It is preferable to separately provide a heat exchanger that heats and heats the bathtub residual water supplied through 8a so that the tap water and the bathtub residual water are not mixed. Of course, the can body provided with the heat exchanger that heats the tap water and the can body that heats the heat exchanger that heats the remaining water in the bathtub may be separately provided and burned and heated by separate burners. it can.

[0012]
Next, an example of the vaporizer 1a constituting the gasified oil fired water heater 1 will be described with reference to FIG.
In this vaporizer 1 a, a dish-like rotary head 11 is provided at the tip of a rotary shaft 12 that transmits the rotational force of a motor 14. The rotary head 11 is provided with an opening in the peripheral direction. A sealing cover 13 for forming a vaporizing chamber 16 is provided in an upper part of the rotary head 11. An oil nozzle 15 for supplying oil from the outside is attached to the rotary head 11 so as not to hinder the rotation of the rotary head 11, and the oil sprayed from the tip of the oil nozzle 15 rotates the rotary head 11. It is diffused to the surroundings by the centrifugal force of time. Further, a preheating heater 17 is arranged around the lower portion of the vaporizing chamber 16, and heat receiving fins 18 are provided around the vaporizing chamber 16 in contact with the heater 17. The heat receiving fin 18 is heated by the heat of the heater 17, so that the oil diffused around by the centrifugal force when the rotary head 11 rotates collides with and contacts the heat receiving fin 18, so that the heat receiving fin 18 holds. It is vaporized and gasified instantly by heat. For example, a time of about 3 minutes is required until the preheating of the heater 17 is completed and the supplied oil is well gasified.
A part of the air from the blower 25 is supplied to the vaporizing chamber 16 through the air passage 20, and the oil and air vaporized in the vaporizing chamber 16 are mixed.
A plurality of burners 19 are arranged below the combustion chamber 22 at regular intervals. The gasified oil descends down the vaporization chamber 16 and is supplied to the burner 19 group. The remainder of the air that has passed through the air passage 20 from the blower 25 becomes secondary air that is supplied to the group of burners 19 and mixed with the gasified oil. In this way, the mixture of gasified oil and air passes through the burner 19 group and escapes upward, and is combusted in the combustion chamber 22 by ignition by the igniter 21. On the combustion chamber 22, a can body 1b is provided. The can body 1b is heated by passing water from the water supply facility 5 or passing residual water from the bathtub 3.
[0013]
Next, an example of specific control by the controller 2b of the washing and pouring control apparatus will be described with reference to the flowchart shown in FIG.
Now, for example, when the external remote controller 2a of the aisle switcher 2 selects either the tap water wash mode, the bath residual water wash mode, the tap water wash mode, or the bath residual water wash mode. The controller 2b of the path switching unit 2 switches the path switching unit 2 to ensure a path corresponding to each mode.
When the operation switch of the external remote controller 2a is turned on, the controller 2b first determines whether or not the hot water washing mode is selected (step S1). In the case of the water washing mode (no in step S1), With a passage in the selected tap water washing mode or bathtub remaining water washing mode secured, a valve (not shown) provided in the passage switch 2 or the like is opened, and tap water or bathtub remaining water to the washing machine 4 is opened. Is supplied (step S4). In this case, when supplying the residual water of the bathtub 3, the pump which is not illustrated is also driven.
On the other hand, when the hot water washing mode is selected (Yes in step S1), the controller 2b obtains information from the gasified oil fired water heater 1 side, and whether or not the heater preheating of the vaporizer 1a is completed. Is determined (step S2). If the heater preheating is completed (Yes in step S2), the hot water supply operation by the gasified oil fired water heater 1 is started, and heated tap water or heated bathtub residual water is supplied to the washing machine 4 ( Step S3).
On the other hand, if the vaporizer 1a of the gasified oil fired water heater 1 is not in a preheated state at step S2 (No at step S2), the controller 2b changes the mode from the hot water washing mode to the water washing mode. Thus, the corresponding water washing mode passage is switched to supply tap water or bathtub residual water to the washing machine 4 in the water washing mode (step S4).
[0014]
Thus, according to the washing and pouring control device according to the above configuration, when the hot water washing mode is selected and the operation switch is turned on by the remote control operation of the external remote controller 2a of the passage switch 2, the gasified oil fired water heater 1 is selected. When the heater preheating of the carburetor 1a is completed, the hot water washing mode is started as it is, and the tap water corresponding to the tap water hot water washing mode or the bathtub remaining water hot water washing mode is selected. Is heated in the can body 1b or the residual water in the bathtub is heated in the can body 1b, so that it can be supplied to the washing machine 4 in the state of immediate hot water and can be washed with hot water.
[0015]
On the other hand, if the heater preheating is not completed, the hot water washing mode is not started, the setting is automatically changed from the hot water washing mode to the water washing mode, and tap water or bathtub residual water is not sent to the can 1b. It will be supplied to the washing machine 4. Therefore, in the state where the heater preheating of the vaporizer 1a is not completed, that is, in the state where it is not combusted, tap water or bathtub residual water is not passed through the can body 1b, and therefore from the can body 1b (made of copper). Generation | occurrence | production of this drain water can be suppressed, and it can prevent that drain water dripping on the vaporizer | carburetor 1a (product made from aluminum die-casting). Therefore, damage due to corrosion or the like of the vaporizer 1a due to a chemical reaction between aluminum ions and copper ions can be prevented, and the lifetime of the vaporizer, and hence the gasified oil-fired water heater can be extended.
[0016]
Furthermore, in the hot water washing mode which is started when the heater preheating is completed, the hot water washing mode for supplying tap water and the remaining hot water washing mode for bathtub remaining water to supply the remaining bathtub water are provided. In the water washing mode adopted when the heater preheating is not completed, etc., the tap water washing mode in which the tap water is supplied as it is without being heated, and the remaining water in the bathtub is not heated. Since any one of the bathtub remaining water washing mode to supply can be selected, the choices for a user increase and the usage according to liking can be performed.
[0017]
In the above embodiment, the case where a gasified oil-fired water heater is used has been described. However, a water heater that can supply hot water without having to wait for completion of preheating by the vaporizer, such as a normal gas water heater, is used. Even in the case where the hot water washing mode is selected and the operation switch of the remote controller 2a of the passage switching device 2 is turned on, the gas water heater or the like is in a state where hot water cannot be supplied immediately for some reason. The controller 2b of the passage switch 2 may change the mode from the hot water washing mode to the water washing mode, and start water supply to the washing machine 4 in the water washing mode. The present invention includes such a case.
[0018]
【The invention's effect】
The present invention is configured as described above. According to the laundry pouring hot water control apparatus according to claim 1, when the hot water washing mode is selected, the gasification oil-fired water heater still gasifies the oil. When the preheating is not completed, the controller is configured to change the mode to the water washing mode and to switch the passage to the passage corresponding to the water washing mode and to control the passage water switch so as to start the water supply.
Even if the preheating for gasifying the oil is not yet completed in the gasified oil fired water heater, even if the operation switch for washing pouring is turned on in the hot water washing mode, the mode is changed to hot water in that case. Since the washing mode is automatically switched to the washing mode, and the passage switcher can automatically switch the passage to a passage that does not pass through the can body, hot water can be supplied with cold water without heating the tap water or the remaining water in the bathtub. It is possible to prevent the container from passing through the can body .
I drain water by the cold water passes can be prevented from occurring in the heat exchanger and around the can body of copper such as I, the drain water is dropped on the vaporizer, such as die-cast aluminum Thus, the corrosion of the vaporizer can be prevented from progressing, and the life of the vaporizer, and hence the gasified oil-fired water heater can be extended.
According to the washing hot water supply control apparatus according to claim 2 , in addition to the effect of the configuration according to claim 1 , the hot water washing mode is a water supply system that supplies tap water to the washing machine by heating the tap water with the passage switch. Either the hot water washing mode or the bathtub residual water hot water washing mode that heats the remaining water in the bathtub by the passage changer and supplies it to the washing machine is selected. The water washing mode heats the tap water by the passage changer. It is made to select from either the tap water washing mode for supplying to the washing machine without using or the bathtub residual water washing mode for supplying to the washing machine without heating the remaining water in the bathtub by the passage switch. So
