When , the low current detection section 31 outputs an output to the fan abnormality detection section 32, and when the fan current becomes If) In compared with the maximum setting current In, the overcurrent detection section 33 outputs an output signal to the fan abnormality detection section 32. issue. The fan abnormality detection section 32 determines that the blower 21 is abnormal based on the signal from the low current detection section 31 or the overcurrent detection section 33, and outputs a signal to stop the operation of the television receiver 13. In FIG. 4, a signal is output to the overheat prevention section 28 to stop the television receiver 13, but various other configurations are possible, such as directly stopping the power supply to the television receiver 13.

By adopting the circuit configuration shown in FIG. 4 as described above, in addition to the temperature control explained in FIG.
Only when f satisfies the condition of In(If(Ix) does the television receiver 13 continue to drive as normal, but when the current If is smaller than In, the blower is not rotating due to a break in the wiring that drives the blower, etc. If the current If is larger than Ix, the blower motor may be locked, so the operation of the television receiver 13 is stopped. Let's do it.

FIG. 6 shows a specific example of the circuit configuration of FIG. 4. Although a detailed explanation will be omitted here, circuit parts corresponding to those in FIG. 4 are surrounded by broken lines and given the same numbers.

In Fig. 5, 34 indicates the operation of the television receiver 13.

Effects of the Invention The bathroom television system and its safety device of the present invention described above have the following various effects.

(1) A TV box that penetrates the bathroom wall and has a built-in TV receiver has a window installed at the bathroom side opening via a sealing material, and a ventilation hole is installed at the protrusion outside the bathroom. , the TV receiver is isolated from the humid bathroom atmosphere, and at the same time, the air between the walls outside the bathroom is introduced into the TV box using a draft effect to cool the TV receiver. Therefore, you can enjoy TV broadcasts safely in the bathroom, where the environmental conditions are bad for electronic devices.

Furthermore, since the TV box is configured to be installed both inside and outside the bathroom, it does not protrude outward from the bathroom and can be installed between walls, and it also saves space in the bathroom.

(2) By installing a blower in the bathroom protrusion of the TV box, the air between the walls can be forced to flow through the TV receiver, making it possible to cool the electronic components.

Therefore, even when the temperature inside the bathroom rises, such as when using a sauna in the bathroom, or when the outside temperature rises due to sunlight, the forced cooling can prevent the TV receiver from deteriorating. A highly reliable system can be realized.

(3) In addition, by installing a temperature sensor inside the TV box and providing a fan drive unit that drives the blower only when the temperature detected by this temperature sensor exceeds a certain temperature, the following problems occur due to constant operation of the blower. It is possible to prevent harmful effects such as In other words, it reduces the noise of the blower, prevents dust from adhering to the TV box or TV receiver and blocking the air vents due to forced airflow, and reduces the operating time of the blower. Durability can be improved.

Furthermore, because the configuration is equipped with an overheat prevention section that temporarily stops the operation of the television receiver when the temperature of the temperature sensor exceeds a predetermined upper limit temperature that is higher than the blower operating temperature, the ventilation port may be blocked or the blower may If the TV receiver does not work for some reason, or if the temperature rises too much and the air blowing capacity is insufficient, stop the TV receiver and let it cool down.
It is possible to prevent accidents such as damage to the TV receiver due to temperature rise and accidents such as fire and smoke.

(4) Furthermore, a low current detection section that detects when the current value of the blower has become below a predetermined minimum current value, and an overcurrent detection section that detects when the current value of the blower has become above a predetermined maximum current value. By installing a fan abnormality detection section that stops the operation of the television receiver based on the signals from these detection sections, it is possible to detect when the blower wiring is disconnected or broken and no current flows, or when the blower Even if the motor locks and an overcurrent flows, it can be detected, achieving double safety and realizing a fail-safe safety device.
