Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crossflow, which can be driven and rotated around an axial center in a sideways posture so that air sucked from an intake port is sent out from a blower port inside a case formed with an intake port and a ventilation port. The present invention relates to a bathroom dryer in which a fan and a heater that heats air sucked from an intake port are arranged.

[0002]

2. Description of the Related Art Conventionally, as a bathroom dryer having the above-mentioned structure, there has been a structure provided on a wall surface of a bathroom as shown in FIG. In the bathroom dryer shown in the figure, an inlet port 01 and an air outlet port 02 are formed on the front side of a horizontally long case C, an exhaust port E is formed on the back side of the case C, and an intake port is provided inside the case C. A cross flow fan F1 driven by an electric motor M1 so as to send out the air sucked from 01 through an air outlet 02, a heater H for heating the air sucked through the air inlet 01, and an air inside the case from an outlet E It houses a sirocco fan F2 driven by an electric motor M2. Further, the crossflow fan F1 and the sirocco fan F2 are arranged in a laterally parallel state inside the case. For example, when heating the bathroom, the crossflow fan F1 is heated with the heater H being heated. To heat the air sucked from the intake port 01 by the heater H, and then send it out from the blower port 02, or when the bathroom is ventilated, the heater is set to a non-heating state to set the sirocco fan F2. It was used in the form of sending air in the bathroom out of the bathroom by driving it.

[0003]

However, in the conventional bathroom dryer shown in FIG. 15, the cross flow fan F1 is used.
Since the sirocco fan F2 and the sirocco fan F2 are housed in the case C, a large volume of the case C is required, resulting in an increase in the size of the case C. Moreover,
Since two electric motors are required to drive the cross flow fan F1 and the sirocco fan F2 independently, there is room for improvement in that not only the structure becomes complicated but also the cost increases. Particularly, in the conventional bathroom dryer, when the air in the bathroom is sent out of the bathroom, the exhaust volume is determined by the ability of the sirocco fan, and there is room for improvement in terms of improving the performance of sending out the air in the bathroom. It was

An object of the present invention is to reasonably construct a bathroom dryer having a simple structure, a small size, and a high performance without impairing the conventional function.

At the same time as heating, it realizes heating with heated air sent out from the air outlet, and in ventilation mode, air is sent out from each exhaust port without giving heat from each heater, so energy is not wasted. To achieve efficient exhaust. As a result, by selecting one of the three control modes as needed, not only efficient heating and ventilation, but even one cross-flow fan can perform ventilation and heating at the same time, and dry the bathroom. Has become possible.

[Operation / Effect] According to the above characteristics, even if the air is exhausted from each of the first exhaust port and the second exhaust port, the air from each of them is merged in the confluent space and then through the duct. The air can be exhausted, and for example, when the opening is formed on the wall surface of the bathroom and the duct is inserted, the opening can be made small. As a result, it is not necessary to form a large hole in the wall surface of the bathroom for exhaust, and even if an opening is formed in the wall surface, a little work is required.

After the fan motor 3 is controlled to drive the crossflow fan 3 at a set speed, the second solenoid valve V2 is opened while the first solenoid valve V1 is closed to open the first and second heaters H1 and H2. By supplying hot water to each of them and setting each of them in a heat generating state, the air sucked from the intake port 1 is heated by the first and second heaters H1 and H2 and sent out from the blower port 2, and the bathroom R
Heating in the form of circulating the above air (# 101
~ Step # 105).

The state of air circulation in the bathroom dryer when the heating control is realized in this way can be indicated by the arrow in FIG. During this control, the air temperature exceeds the set value by controlling the supply amount of hot water from the hot water supply source 5 and the temperature of hot water while feeding back the measured values from the air temperature sensor S1 and the hot water temperature sensor S2.

During this control, the air temperature exceeds the set value by controlling the supply amount of hot water from the hot water supply source 5 and the temperature of hot water while feeding back the measured values from the air temperature sensor S1 and the hot water temperature sensor S2. The control is performed so that the timer does not exist, this control is continued until the time set by the timer is reached, and ends when the time set by the timer is reached (steps # 306 to # 308).

As described above, in the present invention, the single cross flow fan 3 is provided, and the air sucked from the intake port 1 is used for heating by using the full width of the cross flow fan 3 in the axial direction. Since it is sent from, it enables heating,
Further, at the time of ventilation, the air sucked from the intake port 1 is sent to the outside of the bathroom from the first and second exhaust ports E1 and E2 by using the entire width in the axial direction of the cross flow fan 3, which enables efficient ventilation. 4 / of the air sucked from the intake port 1 when drying
At the same time as heating about 5 and sending it from the ventilation port 2 into the bathroom,
Since about 1/5 of the air sucked from the intake port 1 is sent out of the bathroom from the second exhaust port E2 without being heated, it is possible to send out the air containing moisture at the same time as the temperature of the air in the bathroom is raised. There is. In addition, it is possible to suppress the sudden temperature drop in the bathroom by setting the air discharge rate to any value by setting the ventilation rate. In particular, in the present invention, since it is not necessary to provide a fan provided only for sending out the air in the bathroom to the outside, not only the entire apparatus can be downsized, but also the number of parts can be reduced and the cost can be reduced. There is.

[Other Embodiment] In addition to the above embodiment, the present invention adopts, for example, an electric heating type heater using Joule heat as the heater H, or a heat pump type heat source instead of the hot water supply source 7. It is also possible to provide the heat exchange means to heat the heater H.

In the present invention, the first heater H1 and the second heater H1
The area ratio with the heater H2 is any ratio other than 4: 1,
For example, it is possible to carry out by setting it to 1: 1 or by setting it to another ratio, and divide the blower control plate 9 at a ratio corresponding to this ratio, and divide each of the blower control. It is also possible to independently control the posture of the plate 9. When the blow control plate 9 is divided in this way so that the posture control can be performed independently, the blow control plate 9 located on the exhaust side during the control in the drying mode is set to the closed posture. By doing so, more efficient drying is realized.

Further, in the present invention, it is also possible to adjust the air blowing direction by setting the attitude of the air blowing control plate 9, for example,
It is also possible to set the control mode so that the blowing direction can be arbitrarily adjusted by the remote controller 8.
