Abstract

PROBLEM TO BE SOLVED: To eliminate reflection by a water drop so as to prevent malfunction by detecting a user on a toilet seat, and applying a dew condensation preventing treatment to a light transmission body of a sensor of a sanitary washing device that is set in an un-operation state during non-usage. SOLUTION: A sensor is fixed to the rear wall of a casing 14 of a sitting sensor unit 25 in a sanitary washing device 10. The sensor comprises a light emitting element and a light receiving element, and a light transmission body is mounted to an opening of the casing 14 of the sitting sensor unit 25. When a user sits on a toilet seat 16, light from the light emitting element passes through the light transmission body, reflects on the user, and passes again through the light transmission body to the light receiving element. Then, a control device makes a washing mechanism into an operable state. During non-usage of the toilet seat, it does not detect the reflected light and is in an un-operable state. When dew condensation occurs on the light emitting element, the light from the light emitting element is reflected on the dew condensation, is received, and becomes into the operable state even during the non-usage. A water repellent layer is provided on the light transmission body to prevent the dew condensation to prevent failure.

2. Description of the Related Art For example, in a sanitary washing device disclosed in Japanese Patent Publication No. 3-80952, a sensor detects whether or not a user is on a toilet seat. If a user is present, the reflected light of the light emitted from the light emitting part of the sensor is received by the light receiving part of the sensor. If the user is absent from the toilet seat, the control device will allow cleaning and other mechanisms to be activated even if the command button is accidentally (or mischievously) operated. Not to be. As a result, troubles due to malfunctions (such as flooding of the toilet floor due to the discharge of cleaning water) are prevented.

When the user is seated on the toilet seat 16, the light emitted from the light emitting element 20 is reflected by the user after passing through the light transmitting body 30, passes through the light transmitting body 30 again, and receives the light. The device 22 is reached. Then, when the reflected light reaches the light receiving element 22, the control device 40 enables the cleaning mechanism 50 and other mechanisms (not shown) to operate. Then, the operation button group 6
When the cleaning button is operated from zero, the nozzle 52 advances in a well-known manner, and the cleaning water is sprayed from the hole at the tip of the nozzle 52 toward the local part of the user.

Thus, the light transmitting body 30 is formed of the main body 32 and the water repellent layer 34. The formation of the water-repellent layer 34 prevents water droplets from adhering to the light transmitting body 30 due to condensation. The main body 32 is formed of a light-transmitting resin, and has a surface coated with a cyan coupling layer, and further has a hard coat treatment. The hard code processing is performed by forming a 1000 angstrom silicon dioxide film by a liquid phase deposition method.
This is to improve wear resistance. The water-repellent layer 34 is formed by applying a known water-repellent substance.
