Description

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

  2. Description of the Related Art Conventionally, a hot water in a bathtub is used for washing or toilet bowl washing by a device that incorporates a pump and takes water, and a washing machine is preferably mentioned as the device.

  The washing machine has a built-in pump, so that the water intake at the tip of the hose connected to the water inlet 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 pump. To use. 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, it is necessary to take out the hose every time washing is performed and install it between the washing machine and the bathtub. Further, the hose is installed between the bathroom and outside the bathroom. There is a problem 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).
Japanese Utility Model Publication No. 5-55980

  This forms a water intake on the bottom surface of the bathtub, and also forms an air outlet on the wall of the room where the washing machine is installed (or an outer wall when the washing machine is installed outside the room). The intake pipe connected between the two is arranged under the floor or in the wall. A pipe such as a hose is connected between the water inlet and the outlet of the washing machine. Thereby, it becomes possible to take in the remaining hot water of the bathtub through the intake pipe without using the hose as described above, and the above-described problem is solved.

  However, in this case, the remaining hot water of the bathtub remains as residual water in the intake pipe. In other words, the intake pipe is usually a start-up pipe and has many bent portions, and even if the pump is driven with no remaining hot water in the bathtub, air leakage occurs and the intake pipe All remaining hot water could not be taken in, and it remained as residual water.

  There has been a problem in that the remaining hot water remains as residual water in the intake pipe, so that dirt components in the remaining hot water adhere to the intake pipe.

  The present invention has been invented in view of the above-described conventional problems, and the object of the present invention is that the remaining hot water remains as residual water in the intake pipe so that dirt components in the remaining hot water adhere to the intake pipe. It is an object of the present invention to provide an apparatus for using remaining hot water in a bathtub that can be prevented.

  In order to solve the above-mentioned problem, in the apparatus for using remaining hot water of bathtub 2 according to claim 1, a water intake 21 is formed on the bottom surface of the bathtub 2 installed in the bathroom 1, and a pump is built in to take water. An outlet 41 is formed in the wall 40 of the room 4 where the equipment to be performed (washing machine 3) is installed, and the intake pipe 5 connected between the intake 21 and the outlet 41 is placed in the wall 40 or / and under the floor. Disposed, connecting a pipe 32 between the water supply port 31 and the outlet 41 of the device, and providing an empty operation detecting means for detecting the empty operation of the pump, when the empty operation detecting means detects the empty operation, A water supply means 6 for supplying water to the bathtub 2 is provided.

  In the present invention, when the idling operation detecting means detects idling operation, water is supplied to the bathtub by the water supply means, so that the pump air disappears and all remaining hot water in the intake pipe is taken into the equipment, It is possible to prevent the dirt components in the remaining hot water from adhering to the intake pipe.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

  Although the apparatus which incorporates a pump and performs water intake is demonstrated as the washing machine 3 in this embodiment, it is not limited to the washing machine 3.

  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 bottom surface of the bathtub 2. In the present embodiment, although not shown, a water intake member is watertightly fastened to the inner 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. It is attached to. By providing a detachable filter, foreign substances such as hair can be captured and prevented from entering the water intake port 21 and the captured foreign substances can be easily removed. 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. Moreover, although the water supply means 6 which supplies water in the bathtub 2 is provided, this is mentioned later.

  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.

  Further, the intake pipe 5 is provided with an idle operation detecting means for detecting the idle operation of the pump. As the idling operation detection means, one that detects whether or not the current value of the pump is equal to or less than a predetermined value, or one that is provided in the intake pipe 5 and detects water shortage in the intake pipe 5 is used. In the case of detecting water breakage, a pair of electrodes are arranged in the water pipe 5 to detect the current between the electrodes, or when the water intake pipe 5 is a metal pipe, one electrode is taken in the water pipe 5 The presence / absence of water is detected by detecting the current in the electrode and the intake pipe 5 by arranging them in the position.

  The washing machine 3 has a built-in pump, and a pipe 32 such as a hose is connected between the water supply port 31 and the outlet 41 of the washing machine 3.

  In the apparatus as described above, the remaining hot water in the bathtub 2 can be taken into the washing machine 3 through the intake pipe 5 by driving the pump of the washing machine 3. If it disappears, air will generate | occur | produce and all the remaining hot water in the intake piping 5 cannot be taken in, but it remains as residual water. Therefore, by detecting the idle operation of the pump, it is determined that there is no remaining hot water in the bathtub 2, and water is supplied to the bathtub 2 by the water supply means 6.

  The water supply means 6 includes a pipe (not shown) connected to a water source (not shown) such as a water supply to a discharge port 61 such as a curan, an electromagnetic valve (not shown) provided in the middle of the pipe, and an idle operation detection means. And a control unit (not shown) for sending an open / close signal to the electromagnetic valve based on the detection signal.

  When the idling detection means detects idling (preferably continuously detecting for a certain period of time), in response to the detection signal, the control unit sends an open signal to the solenoid valve to open the solenoid valve, and water is supplied to the bathtub 2. Done. At this time, at least the volume of water in the intake pipe 5 is supplied.

  When water is supplied to the bathtub 2, the pump air disappears and all remaining hot water in the intake pipe 5 is taken into the washing machine 3, and the remaining hot water is replaced with the water supplied to the bathtub 2 in the intake pipe 5. .

  According to the configuration as described above, the remaining water in the intake pipe 5 can be made into clean water, and the remaining hot water remains in the intake pipe 5, so that dirt components in the remaining hot water adhere to the intake pipe 5. Can be prevented.

It is a schematic explanatory drawing of this invention.
