Description

The present invention has a ventilation blower that sucks air in the bathroom and discharges it to the outside, a circulation blower that sucks the air in the bathroom and blows the air into the bathroom, and a circulation blower. The present invention relates to a bathroom dryer provided with a bathroom drying unit provided with an air heating unit for heating the air ventilated in the bathroom, and an operation control unit for controlling the operation of the bathroom drying unit.

In such a bathroom dryer, while ventilating the inside of the bathroom, the air in the bathroom is heated by the air heating unit and blown out into the bathroom to dry the objects to be dried such as clothes existing in the bathroom. It is possible to perform operation and bathroom drying operation to dry the bathroom after bathing.

By the way, when the ventilation ventilation unit that sucks the air in the bathroom and discharges it to the outside is activated, the outside air outside the bathroom, such as the air in the dressing room adjacent to the bathroom, is displayed from the gallery provided at the entrance / exit door of the bathroom. Will flow into the bathroom and the inside of the bathroom will be ventilated, and this ventilation will discharge the moisture released from the object to be dried and the moisture evaporated from the wall surface of the bathroom to the outside of the bathroom.
When drying an object to be dried such as clothes after washing, a clothes-drying bar supporting the object to be dried is generally arranged between the opposite side walls of the bathroom, and the object to be dried is placed on the clothes-drying bar. Direct support or support for the hanger holding the object to be dried is performed.

A bathroom dryer provided with a bathroom dryer is often installed on the ceiling of the bathroom, but may also be installed on the side wall of the bathroom.
As the air heating unit equipped in the drying unit for the bathroom, a heat exchanger in which a heat medium from a heat source machine (for example, hot water at 70 ° C. to 80 ° C.) is circulated and supplied is often used, but an electric heater is used. In some cases, an electric heater using the above is used.

As a conventional example of such a bathroom dryer, a remote control for operation is provided with a clothes drying switch and a bathroom drying switch, and a clothes drying operation is performed by a command of the clothes drying switch, and a command of the bathroom drying switch is performed. (For example, see Patent Document 1).

Japanese Unexamined Patent Publication No. 2002-221331

If the clothes drying switch and the bathroom drying switch are provided in the remote control for operation, when the clothes drying operation is performed, the clothes drying operation is instructed by the clothes drying switch to dry the clothes and other objects to be dried. The bathroom drying unit can be operated in a suitable clothes drying operating state, and when the bathroom drying operation is performed, the bathroom drying operation is commanded by the bathroom drying switch, so that the bathroom drying suitable for drying the bathroom is performed. The bathroom drying unit can be operated in the operating state.

However, if the clothes drying switch and the bathroom drying switch are provided in the remote controller for operation, there are inconveniences such as an increase in size of the remote controller for operation. Therefore, it is desired that the remote controller for the operation operation be provided with a single drying command unit (drying switch) for instructing the start of the drying operation.

However, when a single drying command unit (drying switch) for commanding the start of the drying operation is provided on the remote controller for operation operation, a simple pressing operation of the drying command unit (drying switch) can be regarded as a clothes drying operation. Since it is not possible to distinguish between the bathroom drying operation and the command, it is necessary to operate the bathroom drying unit in the same drying operating state in each of the clothes drying operation and the bathroom drying operation.

In this case, the clothes drying operation cannot operate the bathroom drying unit in a clothes drying operating state suitable for drying clothes and other objects to be dried, and the bathroom drying operation can be used to dry the bathroom. There is a disadvantage that the bathroom drying unit cannot be operated in the bathroom drying operating state suitable for the bathroom drying.

By the way, the clothes drying operation is commanded by the short-time pressing operation of the drying command unit (drying switch), and the bathroom drying operation is commanded by the long-time pressing operation (long press) of the drying command unit (drying switch). It is conceivable to distinguish between the clothes drying operation and the bathroom drying operation due to the difference in the operation mode of the drying command unit (drying switch), but in this case, the operation of the drying command unit (drying switch) becomes complicated. , It will be difficult to put into practical use.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a remote controller for operation operation with a single drying command unit for instructing the start of drying operation. It is an object of the present invention to provide a bathroom dryer capable of performing a clothes drying operation in a state suitable for drying an object to be dried and performing a bathroom drying operation in a state suitable for drying a bathroom.

The bathroom dryer of the present invention has a ventilation air blower that sucks air in the bathroom and discharges it to the outside, a circulation air blower that sucks air in the bathroom and blows the air into the bathroom, and A bathroom drying unit provided with an air heating unit that heats the air ventilated by the circulation ventilation unit, and a bathroom drying unit.
An operation control unit for controlling the operation of the bathroom drying unit is provided, and the characteristic configuration thereof is as follows.
A drying target detection unit for detecting the presence or absence of the drying target in the bathroom is provided.
When the operation control unit is instructed to start the drying operation by the drying command unit of the remote controller for operation, the presence or absence of the drying object is determined based on the detection information of the drying target detection unit, and the drying operation is determined. When the object to be dried is present, the clothes drying operation for operating the bathroom drying unit is executed in the preset clothes drying operation state, and when the object to be dried does not exist, the preset bathroom is executed. The point is to execute the bathroom drying operation in which the bathroom drying unit is operated in the drying operating state.

That is, when the drying operation start is commanded by the drying command unit of the remote controller for operation operation, the operation control unit determines the presence or absence of the drying target object based on the detection information of the drying target detection unit.
Then, when the object to be dried is present, the operation control unit executes a clothes drying operation for operating the bathroom drying unit in a preset clothes drying operation state. Further, when the object to be dried does not exist, the bathroom drying operation for operating the bathroom drying unit is executed in the preset bathroom drying operating state.

The operating state for drying clothes can be set to an operating state suitable for drying clothes and other objects to be dried after washing, and the operating state for drying bathrooms dries the bathroom after bathing and the like. It can be set to a suitable operating state.

Therefore, although the remote controller for operation operation is provided with a single drying command unit, when there is an object to be dried, the operation for drying clothes suitable for drying the object to be dried such as clothes is provided. Clothes drying operation to operate the bathroom drying part in the state is performed, and when the object to be dried does not exist, the bathroom drying part is operated in the bathroom drying operating state suitable for drying the bathroom. You can drive.
That is, by simply operating a single drying command unit, it is possible to satisfactorily dry the object to be dried and the bathroom while appropriately selecting the clothes drying operation and the bathroom drying operation.

In short, according to the characteristic configuration of the bathroom dryer of the present invention, the remote controller for operation operation is provided with a single drying command unit for instructing the start of the drying operation, but the clothes drying operation can be performed. It is possible to carry out the drying operation in a state suitable for drying the object to be dried and to carry out the bathroom drying operation in a state suitable for drying the bathroom.

A further characteristic configuration of the bathroom dryer of the present invention is that the drying target detection unit is an infrared detection sensor.
When the operation control unit is instructed to start the drying operation, the operation control unit executes an initial drying operation for operating the bathroom drying unit so as to blow warm air into the bathroom, and detects the infrared detection sensor. The point is to determine the presence or absence of the drying object based on the information.

That is, when the start of the drying operation is instructed, the operation control unit executes the initial drying operation for operating the bathroom drying unit so as to blow warm air into the bathroom.
When the initial drying operation is executed, if there is an object to be dried in the bathroom, warm air flows (contacts) with the object to be dried, and the surface temperature of the object to be dried rises. Therefore, the temperature rise will be detected by the infrared detection sensor, and the operation control unit will determine the presence or absence of the object to be dried based on the detection information of the infrared detection sensor.

By the way, when the warm air flows with respect to the object to be dried, the object to be dried will sway, and the temperature rise portion (temperature rise range) detected by the infrared detection sensor will sway. When the control unit determines the presence or absence of the object to be dried based on the detection information of the infrared detection sensor, if the temperature rise portion (temperature rise range) detected by the infrared detection sensor is shaken, the drying is performed. The existence or nonexistence of the object can be appropriately determined.

Since the infrared detection sensor is small and can be easily installed by installing it near the hot air outlet, it can detect the presence or absence of a dry object in the bathroom. The department can be simplified.

In short, according to the further characteristic configuration of the bathroom dryer of the present invention, it is possible to simplify the drying target detection unit.

A further characteristic configuration of the bathroom dryer of the present invention is that the operation control unit operates the bathroom drying unit in the clothes drying operating state as the initial drying operation.

That is, when the drying start command is commanded, the operation control unit operates the bathroom drying unit in the clothes drying operating state as the initial drying operation.
Then, when it is determined that the object to be dried is present based on the detection information of the infrared detection sensor, the clothes drying operation for operating the clothes drying portion in the clothes drying operating state is subsequently executed. Further, when it is determined that the object to be dried does not exist based on the detection information of the infrared detection sensor, the bathroom drying operation for operating the bathroom drying unit is executed in the preset bathroom drying operating state. ..

In general, when comparing the frequency with which the user performs the clothes drying operation and the frequency with which the bathroom drying operation is performed, the frequency with which the clothes drying operation is performed tends to be higher.
Comparing the operating state for drying clothes and the operating state for drying the bathroom, it is necessary to quickly dry the object to be dried such as wet clothes after washing, and the drying capacity is higher in the operating state for drying clothes. It will be set higher than the operating state for bathroom drying.
In other words, if the bathroom drying unit is operated in the clothes drying operating state, the clothes can be dried satisfactorily and the bathroom can be dried without lack of drying ability.

Therefore, when the drying start command is commanded, as the initial drying operation, the bathroom drying unit is operated in the clothes drying operating state, so that the initial drying operation is performed in order to determine the presence or absence of the object to be dried. However, the clothes drying operation and the bathroom drying operation can be appropriately performed.

In short, according to a further characteristic configuration of the bathroom dryer of the present invention, the clothes drying operation and the bathroom drying operation are appropriately performed while performing the initial drying operation in order to determine the presence or absence of the object to be dried. Can be done.

A further characteristic configuration of the bathroom dryer of the present invention is that the operating state for drying clothes is such that the ventilation air volume of the ventilation air blower and the circulation air volume of the circulation air blower are set to the bathroom drying operation. The point is that it is defined as a form that is more than the state.

That is, the ventilation air volume of the ventilation air blower in the bathroom drying operation state and the circulation air flow amount of the circulation air blower are the ventilation air flow amount of the ventilation air blower in the bathroom drying operation state and the circulation air blower unit. Since it is set to be larger than the circulating air volume of the above, it is possible to sufficiently increase the drying capacity of the clothes drying operation and to prevent the drying capacity of the bathroom drying operation from becoming higher than necessary.

Therefore, in the clothes drying operation, it is possible to appropriately dry the drying object such as wet clothes after washing, and in the bathroom drying operation, it is possible to suppress the drying capacity from becoming higher than necessary. It is possible to dry the bathroom well while saving energy.

In short, according to the further characteristic configuration of the bathroom dryer of the present invention, it is possible to appropriately dry the object to be dried in the clothes drying operation, and to satisfactorily dry the bathroom while saving energy in the bathroom drying operation. can.

A further characteristic configuration of the bathroom dryer of the present invention is that the circulation blower is provided with an air blowing portion that continuously changes the air blowing direction of the air blown into the bathroom between the setting change ranges.
The point is that the clothes drying operating state and the bathroom drying operating state are set so that the setting change range is different.

That is, since the circulation blower section is provided with an air blowout section that continuously changes the air blowing direction of the air blown into the bathroom between the setting change ranges, the air blown into the bathroom by the circulation blower section is provided. Compared to the case where the air blowing direction is maintained in the same direction, in the clothes drying operation, warm air is made to flow toward each part of the object to be dried, and in the bathroom drying operation, each part in the bathroom is made to flow. It is possible to satisfactorily perform clothes drying operation and bathroom drying operation while allowing warm air to flow toward it.

Moreover, since the operating state for drying clothes and the operating state for drying the bathroom are set so that the setting change range in which the air blowing direction is changed is set to a different range, for example, in the clothes drying operation, the object to be dried. In the bathroom drying operation, warm air is blown out over the entire bathroom, etc., in a state corresponding to the clothes drying operation and the bathroom drying operation. Warm air can be blown out well.

In short, according to the further characteristic configuration of the bathroom dryer of the present invention, warm air can be satisfactorily blown out in a state corresponding to the clothes drying operation and the bathroom drying operation.
