Description

  The present invention relates to a quick-heating heating toilet seat that heats a toilet seat in a short time, and particularly relates to a configuration that suppresses a magnetic field generated when a lamp heater is energized.

As shown in FIG. 9, a conventional toilet seat of this type has a toilet seat 102 having a hollow portion 101 inside, and a lamp heater 104 is installed in a U-shape in the hollow portion 101 to seat the heat radiation from the lamp heater 104.

The present embodiment is different from the fifth embodiment in that a holder 21 which is a holding portion for holding one current supply line 3 is cut in a groove portion 19a of a metallic reflector 19 such as stainless steel or aluminum. Since the basic structure of the other heated toilet seat is the same as the structure shown in FIGS. 1 and 5 because it is constituted by the notch 22, FIGS. 1 and 5 are used. Also, the reflector of the right lamp heater 2 shown in FIG. 1 has the same configuration as that of the present embodiment although not shown in FIG.

  In the above configuration, the one current supply line 3 is held by the holder 21, whereby the positional relationship between the one current supply line 3 and the lamp heater 1 is restricted, and a stable magnetic suppression effect can be obtained. Become. Further, since the holder 21 is cut and raised from the cutout portion 22 of the reflection plate 19, no other member or screw for attaching the support portion is required, and an inexpensive configuration with high productivity is possible.

  In the above embodiment, the direction of the current flowing through one of the current supply lines is opposite to the direction of the current flowing through the heating unit such as a filament, and one of the current supply lines is close to the heating unit. The magnetic fields created by the currents passing through each area cancel each other out, and the magnitude of the observed magnetic field is suppressed, and adverse effects on other electrical products are reduced. Therefore, it is possible to realize a heating toilet seat having both low noise and quick temperature.

  In addition, it is wound around the surface of a glass tube in a coil shape, and the magnetic field canceling interaction between the heating part of the lamp heater, which is the main source of noise, and the current supply line flowing in the opposite direction will occur strongly. Thus, it is possible to improve the noise suppression performance.

  Furthermore, one of the current supply lines is branched and installed so as to wrap around the heat generating part of the lamp heater, and is connected to one branch line of the current supply line through which current flows in the opposite direction to the heat generating part of the lamp heater. Interactions that cancel out magnetic fields occur strongly, and noise suppression performance can be improved.

Since they can be set close to each other, it is possible to stably maintain the magnetic field suppression effect by the interaction between the magnetic field canceling out with one of the current supply lines through which the current flows in the opposite direction to the heat generating portion of the lamp heater.

  The lamp seat includes a toilet seat body having a hollow portion, a lamp heater in which a heat generating portion for supplying heat energy to the toilet seat body is covered with a glass tube, and two current supply lines to the lamp heater. The current supply line passes through the back of the lamp, and the current supply line is protected from the high temperature of the heat generating part of the lamp heater, so that power can be supplied safely.

  Further, the side of the reflector that faces the lamp heater is protruded to form a groove along the lamp heater, and one of the current supply lines is installed in the groove close to the lamp heater. Since the position where one of the wires is routed can be defined by the groove, the magnetic field suppression effect can be stabilized.

  Furthermore, since the current supply line support portion is installed in the groove portion of the reflector, the position of the current supply line in the space can be defined, and the magnetic field suppression effect can be stabilized.

  Furthermore, the support part is constructed by cutting and raising the holder of the current supply line from the metal plate that constitutes the reflection plate, so that the holder and the reflection plate can be integrated, making the mounting work more efficient and having an inexpensive holding configuration. Realization is possible.

  As described above, since the heating toilet seat according to the present invention reduces the leakage magnetic field by the configuration of the current supply line, the heating toilet seat can also be applied to uses such as a heat source design that generates a general magnetic field for electric appliances.
