Description

  The present invention relates to an apparatus for using remaining hot water in a bathtub.

  Conventionally, the remaining hot water in the bathtub has been used by a device that incorporates a pump and takes water, and a washing machine is a good example of the device, and the case of a washing machine will be described below.

  The washing machine has a built-in equipment pump. The water intake at the tip of the hose connected to the water supply opening of the washing machine is immersed in the remaining hot water in the bathtub, and the remaining hot water is taken into the washing machine by the driving force of the equipment pump. And used for washing. The washing machine is installed not in the bathroom but in another room such as a changing room or outside. The hose is installed between the washing machine and the bathtub when in use, and stored together in one place when not in use. The

  In this conventional example, the user has to take out the hose every time the laundry is performed and install it between the washing machine and the bathtub. Furthermore, since the hose is installed between the bathroom and the outside of the bathroom, the user has to insert the hose into the bathroom entrance and exit, so that the bathroom door cannot be closed during use.

  Then, what provided the piping for taking in the remaining hot water of a bathtub, without using the above hoses is developed (for example, refer patent document 1).

The bathtub 2 is installed in the bathroom 1, and the bathroom 1 may be a building surrounded by a floor, a wall, and a ceiling of a building frame, or a bathroom unit installed in a bathroom space of a building. A water intake 21 is formed on the side surface or bottom surface of the bathtub 2. In this embodiment, although not shown, a water intake member is watertightly fastened to the inner end edge of the water intake 21 on the bottom surface of the bathtub 2 via a packing, and a filter made of sponge or the like is detachably attached to the water intake member. Attached to. By providing the detachable filter, it is possible to prevent foreign matters such as hair from being captured and enter the water intake 21 and to easily remove the captured foreign matters. Further, a lid member that closes the water intake 21 is detachably attached to the water intake member. By forming the water intake 21 on the bottom surface of the bathtub 2, all the remaining hot water in the bathtub 2 can be introduced into the water inlet 21. In addition, a drain port (not shown) is formed on the bottom surface of the bathtub 2 separately from the water intake port 21. A water supply means 8 for supplying water is provided in the bathtub 2. The water supply means 8 includes a pipe (not shown) connected to a water source (not shown) such as a water supply, and a discharge port 81 provided at the downstream end of the pipe.

  An outlet 41 is formed in the wall 40 of the room 4 where the washing machine 3 is installed. The room 4 in which the washing machine 3 is installed is generally a changing room or a washroom adjacent to the bathroom 1 via a wall 40, but may be separated. When the washing machine 3 is installed outdoors, an outlet 41 is formed on the outer wall 40 in the vicinity where the washing machine 3 is installed.

  A water intake pipe 5 is connected between the water intake 21 and the water intake 41. The intake pipe 5 is made of a synthetic resin flexible pipe or a metal pipe, and is disposed under the floor or in the wall 40.

  For example, when the bathroom 1 is surrounded by the floor, wall 40, and ceiling of the building frame, the intake pipe 5 connected to the intake port 21 from the lower side of the bathtub 2 is buried under the floor below the bathtub 2 to the outside. The inside of the wall 4 of the room 4 in which the washing machine 3 is installed is extended and the inside of the wall 40 is extended upward, and the end is connected to the outlet 41.

  For example, in the case of a bathroom unit, the water intake pipe 5 connected to the water intake 21 of the bathtub 2 passes through a portion below the bathtub 2 of the floor pan, and goes out to the space under the floor pan and on the floor of the cabinet. It is installed in the space facing the outdoors. And between the wall panel of a bathroom unit and the wall of a housing is extended upwards, and the edge part is connected to the outlet 41 penetrated and formed in the wall of the housing. Even in the case of a bathroom unit, the intake pipe 5 penetrating the floor pan is buried under the floor of the cabinet, or enters the wall 40 of the room 4 where the washing machine 3 is installed and extends upward in the wall 40. Also good.

  The washing machine 3 is installed in a waterproof pan 33 provided in the room 4. The washing machine 3 has a built-in equipment pump (not shown), and a pipe 32 is connected between the water supply port 31 and the outlet 41 of the washing machine 3, and the pipe 32 is like a hose. However, various materials such as those made of metal or resin can be used.

  In the apparatus as described above, the remaining hot water in the bathtub 2 is taken into the washing machine 3 through the intake pipe 5 by driving the equipment pump of the washing machine 3. When the remaining hot water in the bathtub 2 is taken in by the washing machine 3, the flow path switching device 6 is provided so that the remaining water remaining in the intake pipe 5 is not taken in.

  The flow path switching device 6 is provided in the pipe 32. In the casing 60, a power source unit, a switching valve 61, flow paths 62 to 64, a pump 65, and a control unit 66 are provided. A power switch and an operation unit (not shown) are provided on the surface of 60 so as to be exposed.

  A cord connected to an external commercial power source or the like is connected to the power supply unit, and electric power is supplied from the outside via the cord, and electric power is supplied to electrical devices such as the switching valve 61, the pump 65, and the control unit 66. Supplied.

  The switching valve 61 is a three-way valve made of an electromagnetic valve, and a flow path 62 to 64 made of a hose, metal, resin, or the like is connected to each port. The flow path 62 is connected so as to communicate with the water intake pipe 5, and the pipe 32 is connected between the flow path 62 and the outlet 41 through an opening (not shown) formed in the casing 60. The The pipe 32 is not particularly limited as long as it forms a flow path. The channel 63 is connected so as to communicate with the water supply port 31 of the washing machine 3, and is piped between the channel 63 and the water supply port 31 through an opening (not shown) formed in the casing 60. 32 is connected. The flow path 64 is connected to communicate with the drain pipe 7 through an opening (not shown) formed in the casing 60. The downstream end of the drain pipe 7 is inserted into a drain port (not shown) formed in the waterproof pan 33. The flow paths 62 to 64 are accommodated in the casing 60 in this embodiment, but may be located outside.

  The pump 65 is connected in the middle of the flow path 64 and is controlled by the control unit 66. The control unit 66 is composed of a microcomputer, has a timekeeping function, and performs switching control of the switching valve 61 and driving / stopping control of the pump 65 in a predetermined flow. Run the flow. The program is stored in a storage device (not shown) such as a ROM, and the drainage time described later is rewritably stored in a storage device (not shown) such as an EEPROM, and these storage devices are connected to the control unit. Is done. The drainage time is set by an input from the time setting unit 67 of the operation unit and stored in the storage device.

  Next, operation | movement of the remaining hot water utilization apparatus of this bathtub 2 is demonstrated.

  When a user intends to take in the remaining hot water in the bathtub 2 into the washing machine 3, first, the user turns on the power switch to start the operation of the control unit. And a user starts operation | movement by operating the operation part of the water intake start among the said operation parts. A control part reads the program and drainage time which are memorize | stored in the memory | storage device, and performs a predetermined | prescribed flow according to a program.

  In the flow, first, the control unit 66 controls the switching valve 61 so that the flow path 62 and the flow path 64 communicate with each other, and drives the pump 65. Thereby, prior to the intake of the remaining hot water in the bathtub 2, the remaining water in the intake pipe 5 is discharged through the drain pipe 7.

Next, the control unit 66, a predetermined time (read drainage time) has elapsed, it stops driving the pump 65, the switching valve 61 and the flow path 62 and the flow path 6 3 controlled to a state that communicates. This drainage time is preferably set to be a time required for draining all the remaining water remaining in the intake pipe 5. Thereby, the pipe 32 to the washing machine 3 and the water intake pipe 5 communicate with each other, and the remaining hot water in the bathtub 2 can be taken into the washing machine 3 through the water intake pipe 5.

  Thus, the control unit 66 ends the flow. Note that the control unit 66 may automatically turn off the power after completing the flow, or may turn off the power after the power switch is manually turned off. Thereafter, the machine pump of the washing machine 3 is operated to take in the remaining hot water in the bathtub 2.

  When the user sets the drainage time, the power switch is turned on to start the operation of the control unit, and then the time setting unit 67 is operated to input and set a desired time. Then, the set time is stored as a drainage time in the storage device, and this drainage time is used the next time the flow is executed.

  In the remaining hot water utilization device of the bathtub 2, when the remaining hot water of the bathtub 2 is taken in, the remaining water of poor quality remaining in the intake pipe 5 is drained and then taken into the equipment. Residual water of poor quality is prevented from being taken into the equipment. Accordingly, it is possible to prevent the occurrence of inconvenience due to residual water having poor water quality (when the device is the washing machine 3 as described above, the laundry clothes are damaged).

  Moreover, since the flow path 64 includes the pump 65, it can be operated independently from the device, and drainage is performed even if the device is not operated.

  In addition, such a flow path switching device 6 can be attached later to a bath remaining hot water utilization device as in the prior art, and it is not particularly necessary to carry it into the device or to be interlocked with the device.

  Further, the drainage time can be set by the time setting unit 67 according to the individual intake pipes 5.
