[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seat heating apparatus in which a toilet seat rotatably supported by a casing mounted on the upper rear portion of a western-style toilet is heated at a temperature suitable for a user to sit on. The present invention relates to a device, and an object thereof is to improve a power feeding device that feeds power to a heater wired inside a toilet seat.

[0002]

2. Description of the Related Art In recent years, with the spread of Western-style toilets, a heater wired in the toilet seat is suitable for the user to sit on the toilet seat so as not to cause discomfort to the user even in winter. Various toilet seat heating devices that keep warm at a certain temperature have been commercialized. An example of the conventionally known toilet seat heating device will be described with reference to FIG. In FIG. 12, reference numeral 1 denotes a casing placed on the upper rear portion of a Western-style toilet (not shown), and a recess 1a recessed on the front side thereof has a toilet seat 2 and a toilet lid 3 mounted on the Western-style toilet, It is mounted so as to be openable and closable using locking pins 4 and 4. Reference numeral 5 is a heater for heating the toilet seat 2 wired on the inner surface of the toilet seat 2. The heater 5 together with a sensor 6 for detecting the toilet seat temperature provided in the vicinity of the heater 5 and a casing 1 via a connection cord 7. It is connected to the controller 8 housed inside. Then, the controller 8 variably controls the energization amount to the heater 5 in accordance with the temperature of the toilet seat 2 detected by the sensor 6,
The surface of the toilet seat 2 is kept at an appropriate temperature at a preset temperature, so that when the user sits on the toilet seat 2, he / she can comfortably step. In FIG. 12, 9 is a power cord for supplying power to the controller 8.

[0003]

In the toilet seat heating apparatus configured as described above, for example, when the toilet seat 2 is soiled by dirty water or the like and the soiled portion is to be cleaned,
In general, a soiled part is wiped off manually by using a rag or the like soaked with a detergent or a disinfectant. However, when wiping off the dirty part using a cloth or the like, it is easy to clean a relatively flat part such as the front and back surfaces of the toilet seat 2, but the dirty part near the pivotal support of the casing 1 on the back surface of the toilet seat 2 should be cleaned. Was difficult. In addition, stains caused by stains on the front and back surfaces of the toilet seat 2 cannot be completely removed even by wiping with a dust cloth or the like, and especially when the toilet seat 2 is erected during small use etc. It was conspicuous and often made the user feel unclean. Further, when cleaning the toilet seat 2, the body was brought close to the toilet bowl for cleaning, and therefore the sense of opposition to the cleaning work was very strong.

Therefore, in order to solve the above problems, in FIG. 12, the locking pins 4 and 4 are removed and the toilet seat 2 is removed.
There is no problem if the toilet seat 2 is removed from the casing 1 and only the toilet seat 2 can be washed with a detergent or the like at another place. However, as shown in FIG.
Since it is connected by the connection cord 7 that supplies power to
Unless the connection with the connecting cord 7 is released, it was difficult to remove the toilet seat 2 from the casing 1 and wash it with water. Although it is possible to disconnect the connection cord 7 by disassembling the casing 1 or the toilet seat 2 and wash the toilet seat 2 with water, not only is it troublesome and time-consuming to disconnect the connection cord 7. When reconnecting the connecting cord 7, it was not possible for the inexperienced person to perform the connecting work because of safety problems, and it was practically impossible to wash the toilet seat 2 with water. It is also conceivable that the connection cord 7 is detachably connected to the toilet seat 2 by a connector or the like so as to be energized, but in this case, the toilet seat 2 can be washed with water, while the toilet seat 2 can be washed. If water remains in the insertion port of the connection cord 7 provided on the second side, there is a problem of causing an electric shock accident or the like when re-energized.

In view of the above-mentioned various problems, the present invention makes it possible to energize a heater wired in a toilet seat without using a connecting cord, and to attach / detach the toilet seat to / from a casing with a simple structure. It is another object of the present invention to provide a toilet seat heating device in which the toilet seat can be removed from the casing and easily washed with water.

[0006]

In order to solve the above various problems, the present invention provides an inverter device for converting a commercial power supply into a high frequency power supply of a predetermined frequency and supplying it to a heater wired in a toilet seat. The toilet seat placed on the upper back is housed in a concave casing that is pivotally supported by a pivot pin so as to be openable and closable. The front of the casing is connected to the AC output end of the inverter device. The side coil is penetrated and projected in a loop shape toward the toilet seat side, and the primary side coil and this primary side coil are penetrated and loosened on the rear upper surface that does not hinder seating of the toilet seat pivotally supported by the casing. At the mating position, a two-part iron core member made of a ferrite core, which is composed of a fixed core fixed to the toilet seat side and a movable core removably engaged and retained in the fixed core, and a predetermined number of times wound around the fixed core side. Being a flight A secondary side electromagnetic induction coil connected to the internal heater constitutes a power feeding means, and the primary side coil connected to the AC output end of the inverter device is loosely fitted in the iron core member and magnetically coupled to the iron core member. As a result, the high frequency power output from the AC output terminal of the inverter device is configured to be supplied to the heater via the power feeding means by the electromagnetic induction action, and the action is as follows.

[0007]

According to the present invention, as described above, the primary side coil connected to the inverter device housed in the casing is projected in a loop shape from the front side of the casing placed on the upper back of the toilet bowl. Since the primary coil is loosely fitted in the iron core member that constitutes the main part of the power feeding means provided on the toilet seat side, the high frequency power output from the inverter device is supplied to the primary coil, and as a result, Magnetic flux is generated in the iron core member in which the primary coil is loosely fitted, and electromotive force is induced in the electromagnetic induction coil wound around the iron core member. That is, an electromotive force is induced in the power supply means by the output of the inverter device, and this electromotive force is supplied from the electromagnetic induction coil to the heater wired in the toilet seat to keep the toilet seat warm at a predetermined temperature. Therefore, it is possible to energize the heater smoothly and satisfactorily without using a connecting cord for energizing the toilet seat.

Since the iron core member is formed by dividing the ferrite core into two parts so that the movable core can be inserted into and removed from the fixed core, the iron core member is connected to the inverter device.
The coupling relationship between the secondary coil and the iron core member can be easily eliminated by pulling out the movable core from the fixed core. Moreover, the toilet seat can be quickly and easily removed from the casing by releasing the pivotal state of the locking shaft that pivotally supports the toilet seat. The toilet seat can be easily separated from the casing and washed in the water without being hindered by the connecting cord.

Secondary coil, secondary core connected to a movable core and a fixed core in which a ferrite core is divided into two and separably provided, and a heater in a toilet seat wound around the fixed core side of the iron core member. Side electromagnetic induction coil is provided, and the primary side coil is loosely fitted and penetrated by using a movable core mounted in the fixed core of the iron core member so as to be able to come into contact with and separate from the fixed core. Thus, since the high frequency power output from the inverter device is configured to energize the heater by utilizing the electromagnetic induction effect, it is possible to energize the heater without using a connection cord. As a result,
Since the cordless connection between the toilet seat and the casing can be effectively achieved, and the toilet seat can be removed from the casing and washed with water, the toilet seat can be cleaned hygienically and quickly and easily. Can be kept clean for a long time.

The toilet seat is rotatably and pivotally supported on the casing by using a movable shaft that rotates in the front-rear direction with respect to the casing, and the iron core member of the power feeding means provided on the toilet seat is used as an AC output of the inverter device. Since it is configured to be separably connected to the primary side coil connected to the end, when the toilet seat is attached to or detached from the casing, the toilet seat may be pulled toward the front side with the open end side of the fixed core open. Since the toilet seat can be easily detached from the casing or attached to the casing by pushing back, the toilet seat can be smoothly and satisfactorily attached to and detached from the casing.
