Description

TECHNICAL FIELD The present invention relates to a bathroom ventilation dryer that blows warm air into a bathroom to dry laundry and the like, and to dry, ventilate and heat the bathroom.

2. Description of the Related Art A conventional bathroom ventilation dryer will be described with reference to FIGS. 2 and 3. A main body 1 of the bathroom dryer is provided with an outdoor outlet 2 communicating with the outside, and a fan 3 for blowing air is provided on the main body. Have 1
Two blower electric motors 4, electric dampers 5 and heaters 6 are attached, while the front air intake 7 on the bathroom side that communicates with the bathroom
And a front grill 9 having a bathroom-side discharge port 8 are provided. Drying and ventilation are performed at regular intervals by changing the air passage by opening and closing the electric damper 5.

Fig. 2 is a block diagram of the bathroom ventilation dryer in the dry mode, showing the air flow when the electric damper 5 is open.

The moist air in the bathroom is sucked from the bathroom-side suction port 7 by the blower fan 3 and the electric damper 5 works to blow warm air from the bathroom-side discharge port 8 to the laundry in the bathroom through the heater 6. Evaporate the applied water.

When it is sprayed for a certain period of time, the timer of the remote control operates and switches to the ventilation mode shown in Fig. 3.

Fig. 3 is a block diagram of the bathroom ventilation dryer in ventilation mode, showing the flow of air when the electric damper 5 is closed.

The moist air in the bathroom is sucked from the bathroom side suction port 7 by the blower fan 3, but the electric damper 5 closes the direction of the heater 6 and the steam discharged from the outdoor discharge port 7 fills the bathroom to the outside. It will be discharged.

When the electric damper 5 is closed, the power supply to the heater 6 is cut off.

After ventilation for a certain period of time, it automatically returns to the drying mode shown in Fig. 2.

Dry the laundry by repeating the drying mode and ventilation mode as described above.

However, during ventilation, warm humidity is discharged to the outside,
Although humidity decreased, the temperature in the bathroom also drastically decreased, and even if the temperature was switched to the dry mode and reheated, there was a loss of time before reaching the room temperature before ventilation, and it took a long time to dry.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention eliminates the conventional drawbacks and provides a bathroom ventilation dryer with improved drying efficiency of laundry.

Means for Solving the Problems The present invention has two kinds of electric motors for ventilation and ventilation. The ventilation electric motor has two speeds, strong and weak, weak when drying laundry and strong when ventilation in the bathroom. It has a weak function.

Work In the present invention, at the time of drying, hot air is blown out by the blower motor, and at the same time, the ventilation motor is weakly operated to constantly discharge moisture.

During ventilation, by independently operating the electric motor for ventilation strongly or weakly, moisture such as water vapor in the bathroom can be ruptured and discharged.

Further, by taking in dry air from the outside of the bathroom to create a flow of air, the inside of the bathroom is ventilated, and moist air is discharged to make the bathroom easier to dry.

Embodiment An embodiment of the present invention will be described with reference to FIG. In the figure, reference numeral 1 is a main body of a bathroom ventilation dryer, a front grill 9 having a bathroom suction port 7 and a bathroom-side discharge port 8 is attached to the front surface, and an outdoor discharge port 2 is provided at the rear part of the main body 1. .

A fan casing 10 is provided inside the main body 1, and an air passage 11 extending from the bathroom-side suction port 7 to the bathroom-side discharge port 8 is formed.

The fan casing 10 has a blower fan 3 built therein and is covered with a fan casing cover 12.

The air flow path 11 is formed up to the end of the main body 1, and is provided with a heater base 13 that abuts the fan casing cover 12 to fix the heater 6, and the heater 6 is provided at a position facing the bathroom-side discharge port 8. It is installed.

With the above-described configuration, when the blower electric motor 4 having the blower fan 3 is operated at the time of drying, the air in the bathroom is sucked through the bathroom side suction port 7, passes through the blower fan 3, and is heated from the air passage 11 of the fan casing 10. After being warmed in 6, warm air blows from the bathroom outlet 8 to the bathroom side and sprays it on the laundry to evaporate the moisture.

Moreover, in order to dry the laundry in a shorter time, when the ventilation electric motor 15 having the ventilation fan 14 is weakly operated at the same time as the blower electric motor 4, the moist air in the bathroom is sucked from the bathroom side suction port 7. As a result, moisture can be constantly discharged to the outside through the ventilation fan 14 and the outdoor outlet 2 in the rear part of the main body 1, so that the laundry can be dried more quickly and the laundry needs to be dried in this state. Otherwise, it will be possible to dry and heat the bathroom.

Further, during ventilation, the ventilation motor 15 is operated independently by strong or weak operation to suck in dry air from outside the bathroom through the bathroom-side suction port 7 and circulate the moist air in the bathroom to circulate in the bathroom. Ventilate.

In this way, by changing the strength of the ventilation electric motor 15, the functions for ventilation and the function for drying can be provided.

In addition, as another way to use this bathroom ventilation dryer, when the laundry is not dried, the ventilation motor 15 is operated strongly or weakly in the summer to circulate it in the bathroom, and in the winter it circulates. It can be used for drying and heating in the bathroom by slightly operating the motor 4 for ventilation and the motor 15 for ventilation, so you can manage the bathroom in an optimal state all year round, so you can enjoy bathing in a comfortable state.

Effects of the Invention As described above, the present invention has the following effects.

(1) At the time of drying, by simultaneously operating the blower fan that blows out warm air and the ventilation fan, the dry air is constantly taken in from the outside, and at the same time, the drying efficiency is enhanced because the humidity is also discharged to the outside. The time can be shortened and the economic effect can be improved.

(2) Since the ventilation motor is of the strength switching type, one motor can have two functions, one for ventilation and the other for drying, which reduces the number of parts and the cost.

(3) By combining the circulation motor and the ventilation motor, it is possible to dry laundry, dry the bathroom, and perform ventilation and heating.

As described above, according to the present invention, it is possible to provide a bathroom ventilation dryer having a large practical effect that is capable of efficiently drying laundry without keeping moisture in the bathroom and also capable of drying, ventilating and heating the bathroom. is there.
