Description

  The present invention relates to an automatic washing hot water supply apparatus for a bathtub, and more particularly to a technique for controlling an electric drain plug, an automatic bathtub washing apparatus, and an automatic hot water heater.

When draining or hot water from a conventional bathtub, the bathtub drain plug is manually opened and closed, so it is necessary to go to the bathroom and manually open and close the drain plug. In the same way, it is usually necessary to go into the bathroom and generally rub it with a sponge with a detergent, etc., and it is necessary to stretch out the arms and bend the waist, which is painful. An automatic drainage hot water supply equipped with a control unit for continuously executing a series of operations from draining to cleaning to hot water beam after bathing is provided with an electric drain plug, an automatic bathtub cleaning device and an automatic hot water beam device in the bathtub An apparatus is known (see, for example, Patent Document 1).

However, as seen in Patent Document 1, in a control method in which a series of operations from drainage to cleaning to hot water is continuously performed, for example, when cleaning immediately after the final bath, the hot water is automatically performed after cleaning. If a long time elapses from this hot water until the next bathing, the temperature of the hot water will drop when bathing next time, and additional cooking will be required. Also, when cleaning just before bathing, if a long time has passed since the end of the previous bathing, the bathtub will remain dirty for a long time, and dirt will stick to it, and automatic cleaning with detergent spray alone will be enough to clean The problem of being unable to do so arises.

  An operation remote controller 34 for selecting either or both of the automatic drain / cleaning mode and the automatic closing / hot water supply mode set in the control unit 8 is installed inside or outside the bathroom 1. The operation remote controller 34 is wired to the control box 26 by a remote control cable, but may be wirelessly connected. The operation remote controller 34 includes an “automatic drain / wash” button 35 for selecting an automatic drain / wash mode and an “automatic plug / hot water” button 36 for selecting an “automatic plug / hot water supply mode”.

  Next, an example of the operation of the automatic cleaning hot water supply apparatus will be described.

  First, when the user presses only the “automatic drain / clean” button 35 of the operation remote controller 34, the control unit 8 executes only the automatic drain / clean mode. That is, the electric drain plug 10 is opened to drain the bath water. At this time, if the bath lid 16 is not installed, a warning prompting the operation remote controller 34 to install the bath lid 16 is received from the signal of the bath lid detection sensor 15 provided on the flange surface 3 a of the bathtub 3. Done. When the bath lid 16 is normally set, the operation of the blower 20 is started after a certain time (about 20 minutes) after the “automatic drain / wash” button 35 is pressed. As a result, air is pushed from the air pipe 18 into the upper portion of the detergent tank 27, whereby the detergent 29 is sprayed into the bathtub 3 from the detergent spray nozzle 30. Further, after spraying the detergent, the electromagnetic valve 23 is opened after a certain time (about 10 minutes), and tap water is sprayed from the fresh water spray nozzle 44 for a certain time (about 5 minutes) to rinse. During the execution of the detergent spray and the fresh water spray, the check valves 19 and 22 are provided in the path of the fresh water and the detergent 29, so that the detergent 29 flows back to the blower 20 and breaks down, or the tap water is sewed. Will not flow backwards. And after cleaning of the bathtub 3, the heating ventilation dryer 2 starts a driving | operation automatically, and the inside of the bathroom 1 is dried. A series of operations of draining, cleaning, and drying is automatically performed by a single operation of the “auto drain / wash” button 35. When this automatic drain / wash mode is completed, the electric drain plug 10 is kept open.

  On the other hand, when the user simultaneously presses both the “automatic drain / wash” button 35 and the “automatic plug / hot water” button 36 of the operation remote controller 34 or after pressing the “auto drain / wash” button 35 (auto drain / When the “automatic closing / hot water supply” button 36 is pressed during the execution of the cleaning mode, in any case, the automatic closing / hot water supply mode is automatically executed following the end of the automatic drain / cleaning mode. When the user presses only the “automatic closing / hot water supply” button 36, the drainage and cleaning of the bathtub 3 are not performed, and only the closing and hot watering operations of the electric drainage plug 10 are automatically performed.

  That is, when the automatic closing / hot water supply mode is selected, the control unit 8 first closes the electric drain plug 10. At this time, the open / close detection sensor 13 provided in the electric drain plug 10 detects whether or not the electric drain plug 10 is normally closed. Further, the bath lid detection sensor 15 detects whether the installation state of the bath lid 16 is normal. When an abnormality occurs in the installation state of the bath lid 16 or the electric drain plug 10, the control unit 8 stops its operation and issues a warning to the operation remote controller 34 by voice. When there is no abnormality, the water heater 6 is automatically operated to start hot water feeding. A series of operations from closing the electric drain plug 10 to hot water is automatically performed by a single operation of the “automatic plug / hot water” button 36.

  Therefore, according to this apparatus, since the electric drain plug 10, the automatic bathtub cleaning device 50, and the water heater 6 of the bathtub 3 can be centrally controlled by the operation remote controller 34 from a location away from the bathroom 1, the reciprocating movement to the bathroom 1 is possible. Can be greatly reduced. In addition, since the automatic drain / wash mode and the automatic capping / hot water supply mode can be selected continuously or not by the operation remote controller 34, it is possible to select the automatic drain / wash mode after the last bath, so that time is not spent after the last bath. Since it can be cleaned, the effect of removing dirt from the bathtub 3 can be enhanced, and the labor of manual cleaning can be greatly improved. In addition, by selecting the automatic capping / hot water supply mode before the next bathing, you can bathe without taking time from the hot water so that the temperature of the hot water does not drop and you can save the energy required for additional cooking It is.

  Moreover, since the control part 8 of this example detects the installation state of the bath lid 16 with the bath lid detection sensor 15, and controls so that the automatic bathtub washing apparatus 50 does not operate | move in the state without the bath lid 16, the bath lid 16 Since there is no spraying of the detergent 29 in the absence of the detergent 29, the detergent 29 is not adhered to any part other than the bathtub 3, and the bathtub 3 can be cleaned with peace of mind. Furthermore, since the open / close detection sensor 13 detects the open / close state of the electric drain plug 10 and prevents the automatic hot water pouring operation by the water heater when the electric drain plug 10 is opened, the hot water can be safely and securely. A beam can be made. Further, when an abnormality occurs in the installation state of the bath lid 16 or the electric drain plug 10, the control unit 8 stops the automatic bathtub cleaning operation and the automatic hot water heating operation, and warns by voice from the speaker 40 of the operation remote controller 34. Therefore, the user can be immediately notified of the abnormality, and there is an advantage that the automatic cleaning hot water supply apparatus can be used more safely and safely.

  Further, in the automatic drain / wash mode, the heating / ventilation dryer 2 is automatically operated after the bathtub washing operation, so that the bathroom is dried after the bathtub 3 is cleaned until the next bathing. It is possible to easily remove the moisture in 1 and water droplets adhering to the wall surface due to condensation. In particular, when the time from cleaning the bathtub 3 to the next hot water is long, the bathroom 1 can be kept dry, which is effective in preventing mold.
