Description

[Detailed description of the invention] This invention relates to an instrument for storing toothbrushes and for drying and sterilizing them.

Conventionally, toothbrushes have been stored in cases, holders, etc. after use.

However, toothbrushes are not sufficiently dried after use, and if they are stored in a case or holder in this state, they are unhygienic as they tend to attract dust and bacteria.

In view of the above-mentioned drawbacks of the conventional art, the present invention aims to improve this and provide a dryer that can sterilize and dry toothbrushes and store them hygienically.

The configuration of the present invention will be explained below according to the embodiments shown in the drawings.

In Figures 1 to 3, 1 is a main body, and this main body 1 has a cylindrical shape, and as shown in the figure, the lower part is slightly enlarged in diameter, and air flows through the middle part and lower end of the side wall. Hole 2
, 3.

Further, a bottom wall 4 is provided slightly above the lower end of the main body 1, and a hollow support 5 is provided in the center of the bottom wall 4.

This support 5 extends upward to approximately the same height as the upper end of the main body 1, and forms a housing space 7 for the toothbrush 6 between it and the inner surface of the side wall of the main body 1.

Reference numeral 8 denotes a socket inserted and fixed at the tip of the support column 5, 9 an air circulation hole bored in the middle of the support column 5, and 10 a blower fan installed in the lower space inside the support column 5 and its motor.

The socket 8 is equipped with a heat source, for example, a 20W to 40W infrared light bulb 11.

The heat source may also be a PTC heating element (PTC is a trade name) or a coil heater.

An electronic timer circuit 12 attached to the lower side of the bottom wall 4 is connected to the socket 8 via a conductive wire 13.

Switches 14 and 15 and a W cord 16 provided at the bottom of the main body 1 are connected to the electronic timer circuit 12, and a plug 17 is provided at the tip of the power cord 16.

Reference numeral 18 denotes a ring-shaped water receptacle that is removably fitted in close contact with the inside of the main body 1, the bottom wall 4, and the lower part of the support column 5, and 19 is a cylindrical member that fits into the upper end of the support support 5.

The cylindrical member 19 has partition blades 20 radially provided on its side circumferential surface, and an infrared light bulb 11 as a heat source at the upper end.
It has a light bulb cover 21 that covers.

Reference numeral 22 denotes a lid detachably fitted onto the upper end of the main body 1.

Air circulation holes 23 are provided on the top surface of the lid 22.

Next, the operating procedure of the toothbrush sterilizing dryer constructed as above will be explained.

First, after washing the toothbrush 6 after use, it is stored in the main body 1 and the switch 14 is turned on.

When the switch 14 is turned on, the electronic timer circuit 12 is activated.
Current is supplied to the infrared light bulb 11 for a predetermined period of time, and the blower fan and motor 10 are operated for the same period of time.

The toothbrush 6 is tilted at an angle of 65 degrees due to the radiant heat of this infrared light bulb 11.
It is heated to 75°C to begin drying.

The heated and evaporated moisture flows out from the air circulation holes 23 of the lid 22 together with the air, and new air flows in from the air circulation holes 2 and 3 of the main body 1.

The air flowing in from the air circulation hole 2 flows through the toothbrush housing space 7 to the air circulation hole 23 of the lid 22, and the air flowing in from the air circulation hole 3 flows into the air blowing fan and motor 10.
The air is forcibly blown and sent to the toothbrush housing space 7 through the internal space of the support column 5 and the air circulation hole 9 of the support column 5, and flows out through the air circulation hole 23 of the lid 22 to the outside.

It should be noted that it is sufficient to supply fresh air to the toothbrush storage space 7 only through the air circulation hole 2 bored in the middle part of the cylindrical side wall of the main body 1, but in this case, it is sufficient to supply fresh air to the toothbrush storage space 7. Due to the temperature difference, dew may form on the inner surface of the lid 22.
Unfavorable in terms of hygiene and appearance.

Further, if there is only the air circulation hole 2, the cooling effect due to the airflow is insufficient, and the handle 6a of the toothbrush 6 is heated to a high temperature.
There is a risk of deformation.

Moreover, since the toothbrushes 6 are sterilized and dried by the radiant heat of the infrared light bulb 11, the amount of radiant heat received by each toothbrush 6 differs depending on the orientation of the toothbrush 6, and there is a possibility that the sterilization and drying effect will vary.

Therefore, in consideration of the above-mentioned circumstances, the present invention prevents dew condensation by forcibly blowing air from the air circulation hole 9 in the middle part of the support column 5 to the accommodation space 7 using a blower fan and motor 10, and also cools the handle 6a. This prevents deformation, and furthermore, the toothbrush 6 receives substantially uniform radiant heat regardless of the orientation of the toothbrush 6.

Therefore, it is possible to use a small-capacity heat source, and the time required for sterilization and drying can be shortened.

After a predetermined period of time has elapsed, the water in the toothbrush 6 is completely evaporated, dried, and sterilized.

After the switch is turned on, when the set time of the timer circuit 12 has elapsed, the supply of current to the infrared light bulb 11, the blower fan, and the motor 10 is cut off, and the sterilization drying is completed.

The switch 15 is a switch for disconnecting the timer circuit 12, which is provided to prevent the inside of the toothbrush housing space 7 from being abnormally heated during use in warm weather.

As explained above, the present invention provides air circulation holes in the middle and lower end of the cylindrical side wall, a bottom wall slightly above the bottom of the cylindrical side wall, and a hollow hole in the center of the bottom wall. A toothbrush accommodating space is formed between this support and the inner surface of the cylindrical side wall by erecting a support, and a drying and sterilization container is installed on the support at a position approximately at the same height as the toothbrush housed in the space. A heat source is provided, an air circulation hole is bored in the middle side wall surface of the support, a blower fan is installed in the internal space of the support, and the current supplied to the heat source and the blower fan is controlled below the bottom wall. Since a timer is provided and a lid having air circulation holes is removably placed on the upper part of the cylindrical side wall, it is possible to provide an inexpensive dryer in which a toothbrush can be stored hygienically.

In addition, the forced air effect of the blower fan allows the use of a small-capacity heat source and shortens the time required for sterilization and drying.

Furthermore, it is excellent in preventing condensation inside the lid in cold regions and preventing deformation of the handle due to abnormal heating, and can provide uniform radiant heat to each toothbrush regardless of its orientation.
