Abstract

PURPOSE:To produce an sufficient deodorizing effect at a necessary minimum running cost, by providing a delay circuit which immediately stops energization to a heater unit when a switch is turned ON but continues energization to a fan motor for a given time. CONSTITUTION:When a user performs a work and parts from a device body and exists a room, a human body detecting device 8 does not detect the existence of a human body and a switch 9 is opened, an energizing circuit to a heater unit 6 is opened, and generation of heat by the heater unit 6 is stopped. But, since an energizing circuit to a fan motor 5 is closed in succession through the working of a timer relay 10 for a given time, drive of the fan motor 5 is continued, and a propeller fan 4 is run and therefore, circulation of air is effected, and a deodorizing action is continued. When a time previously specified in the timer relay 10 lapses, an energizing circuit to the fan motor 5 is opened through the action of the timer relay 10 and therefore, the fan motor 5 is stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a hot air fan equipped with a deodorizing function.
・It is.

Conventional technology Conventionally, this type of hot air fan has an air outlet on the top surface of the main body case and an air intake port on the bottom front surface, and a propeller fan for blowing air and a propeller fan for blowing air inside the main body case. It was equipped with a fan motor for driving the propeller fan, a heater unit provided above the propeller fan, and a breathable deodorizer provided below the propeller fan. In addition, a two-pole, single-throw main switch is provided on the top of the main body case, one pole of this main switch is connected to the heater unit, and the other pole is connected to the timer installed inside the main body case. It was connected to a relay, and a fan motor was also connected to the timer relay. When the main switch is closed, the timer relay closes the energizing circuit to the fan motor, and even if the main switch is opened next, it continues to close the energizing circuit to the fan motor for a prespecified period of time from that point on. Once that time has passed, it automatically opens the energizing circuit to the fan motor.
It's 7.

In the above configuration, when the user closes the main switch, the heater unit is energized and generates heat, and at the same time, the timer relay is energized, which activates the timer relay and closes the energizing circuit to the fan motor. As a result, the fan motor is driven and the propeller fan rotates, causing air circulation. Indoor air is sucked in from the air intake port provided at the bottom front of the main body case, and the ventilation Odor components such as ammonia and hydrogen sulfide are adsorbed by the deodorizer, pass through the 7' lobe fan, pass through the heater unit installed above the propeller fan, and become warm air, which is installed at the front of the upper part of the main body case. It is released into the room from the air outlet.

When a user relieves himself and leaves the toilet, opening the main switch opens the energizing circuit to the heater unit, which stops the heater unit from generating heat. However, due to the action of the timer relay, Since the current supply circuit to the fan motor is continuously closed, the fan motor 5 continues to be driven, and the propeller fan rotates, so that air is circulated and the deodorizing effect continues. When the time specified in advance by the timer relay has elapsed, the timer relay operates and the energizing circuit to the fan motor is opened, thereby stopping the fan motor. If you set the timer relay in advance to a time that is long enough to complete the removal of odor components in the toilet, you can obtain the desired deodorizing effect with the minimum necessary running cost. Ta.

Problems to be Solved by the Invention In such a conventional configuration, the fan continues to operate even after the user leaves the toilet, so the switch may be turned off due to a switch operation error by the user. If there is no fan or if you forget to turn off the switch, you may leave the room without noticing.In that case, not only will the fan continue to operate, but the heater unit will continue to generate heat. Not only is it dangerous, it is also uneconomical.
Furthermore, there was the problem that it was troublesome to turn on the switch every time you entered the toilet.

The present invention solves these problems by providing a safe hot-air fan with a deodorizing function that can provide a sufficient deodorizing effect with minimal running costs and that automatically and reliably opens and closes the switch. The purpose is to provide

Means for Solving the Problems In order to solve this problem, the present invention provides a main body case provided with an air outlet and an air suction port, a human body detection device for detecting whether or not a user has entered the room, and A fan installed inside the main body case, a fan motor that drives this fan,
a heater unit provided between the air outlet and the fan; a deodorizer provided between the air suction port and the fan; and a deodorizer interlocked with the human body detection device; Energizing circuit to the motor t4F] is equipped with a switch that closes, and when this switch is opened,
The hot air fan with a deodorizing function has a 67,-7 configuration having a delay circuit that immediately stops power to the heater unit but continues power to the fan motor for a predetermined period of time.

With this configuration, when a user enters the toilet, the body detection device automatically operates the device and blows out deodorized warm air, and when the user leaves the toilet after using the toilet. When deodorizing, the human body detection device automatically stops the heat generation of the heater unit again, but the delay circuit continues to operate the shift fan motor for a predetermined period of time, so the deodorizing function does not reach the predetermined time. It will work continuously for an hour and then stop automatically.

EXAMPLE Hereinafter, an example of the present invention will be explained based on FIGS. 1 to 3.

In the figure, there is an air outlet 2 on the upper front of the main body case 1.
However, an air suction port 3 is provided on the lower front surface, and a fan motor 5 that drives a propeller fan 4 for blowing air and a heater unit 6 provided above the propeller fan 4 are installed inside the main body case 1. and a deodorizer 7 for ventilation 7 provided below the propeller fan 4. In addition, the main case 1
A human body detection device 8 is provided on the front of the main body case 1.

A fan motor 6 is connected to the relay 1o. Switch 9 is human body detection device 8
Human body detection device 8 is closed only while detecting a human body.
The timer relay 10 functions to open when the switch 9 no longer detects a human body, and the timer relay 10 opens the fan motor 6 when the switch 9 is closed.
When the switch 9 is opened, the current supply circuit to the fan motor 6 is closed for a pre-specified period of time from that point on, and the fan motor 6 is automatically turned off after that time. It functions to open the energizing circuit to the motor 5.

In the above configuration, when the user enters the toilet and is located in front of the main body of the device, the human body detection device 8 detects a human body and when the switch 9 is closed, the heater unit 6 is energized, so that the heater unit 6 generates heat. At the same time, the timer relay 1o is activated because the timer relay 10 is energized, and the energization circuit to the fan motor 6 is closed, so the fan motor 6 is driven and the propeller fan 4 is rotated.

Air circulation occurs as the propeller fan 4 rotates, indoor air is sucked in from the air suction port 3 provided at the lower front of the main body case 1, and ammonia is added to the breathable deodorizer 7 provided below the propeller fan 4. - After odor components such as hydrogen sulfide are adsorbed, the propeller fan 4 is energized, passes through the heater unit 6 installed above the propeller fan 4, becomes warm air, and is provided at the upper front of the main body case 1. The air is discharged into the room from the air outlet 2. When the user relieves himself and leaves the device, the human body detection device 8 no longer detects a human body and the switch 9 is opened, so the energizing circuit to the heater unit 6 is opened and the heater unit 6 stops generating heat. However, due to the action of the timer relay 10, the current supply circuit to the fan fan motor 6 is closed, so the drive of the fan motor 6 continues, and the propeller fan 4 rotates, so that the air is turned off. circulation is carried out, and the deodorizing effect continues. When the time specified in advance by the timer relay 10 has elapsed, the operation of the timer relay 10 opens the current supply circuit to the fan motor 6, so that the fan motor 6 stops.

Here, the time specified in advance for timer relay 1o is
All you have to do is set it to a time long enough to complete the removal of odor components in the toilet.

Note that a constant OFF switch may be provided for the heater unit θ so that it can be used in seasons other than winter.
