It is.

According to the present invention, the air to be dried can be uniformly distributed to the object to be dried.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION
By providing the air blowing ports for feeding air into the storages, uniform drying can be realized by blowing air from different directions at the time of drying the dishes.

According to a second aspect of the present invention, in addition to the first aspect of the present invention, first and second blower impellers are arranged at both ends of the electric motor, and a pair of intake ports and an intake path are provided outside the machine. By sending air to the first or second blower impeller and arranging the electric motor in the intake passage, the air outside the machine is first blown through the intake port, the intake passage, and the electric motor when the electric motor rotates forward. After being supplied to the impeller and pressurized, the air is blown into the storage via the first blowing path and the first blowing port. Also, when the motor is reversed, the air outside the machine is
After being supplied to the second blowing impeller via the electric motor and pressurized, the air is blown into the storage via the second blowing path and the second blowing port. Therefore, the air outside the machine is supplied to the motor via the intake port and the intake path irrespective of the forward or reverse rotation of the motor, so that the motor is cooled without separately providing a cooling-dedicated impeller. Therefore, the electric motor can be configured in a space-saving and inexpensive configuration, and the electric motor is reliably cooled by the outside air blown from the set of intake ports and the intake path regardless of whether the electric motor is rotating forward or inverting. be able to. Further, by disposing the first and second blower impellers at both ends of the shaft of the motor, the load balance on the shaft of the motor can be made substantially uniform without biasing to one side. Therefore, it is possible to adopt a configuration for improving the durability of the electric motor.

According to a third aspect of the present invention, there is provided a storage for accommodating an object to be dried, a heating element for heating air or the object to be dried, a blower operated by a motor, and a first blower constituting the blower. , A second blowing impeller and a first, a second blowing casing, and a first, a second intake port and a first, a second intake path for sending outside air to the first and second blowing impellers, The first and second ventilation paths for connecting the storage and the first and second ventilation casings, the first and second air outlets for feeding air into the storage, and the air in the storage outside the machine. The first and second blow impellers operate when the electric motor is driven in the forward direction. At this time, the first blower impeller pressurizes the air outside the machine, and the second blower impeller does not pressurize the air outside the machine. Then, the air is sent to the first airflow impeller via the first air intake path, pressurized, and supplied into the storage via the first airflow path and the first air outlet. Then, the air outside the machine supplied into the storage is heated by the heating element to become warm air, and is blown to the object to be dried or the like. The object to be dried is dried, and then discharged from the exhaust port to the outside of the machine. On the other hand, when the motor is driven in the reverse direction and the first and second blowing impellers operate, the second blowing impeller pressurizes the outside air, and the first blowing impeller does not pressurize the outside air. Therefore, the air outside the machine is sent to the second blow impeller through the second intake port and the second intake path by the second blow impeller and is pressurized, and the second blow path and the second It is supplied into the storage via the air outlet. Then, similarly to the case of driving the electric motor in the normal rotation direction, the outside air supplied into the storage is heated by the heating element to be heated, and is blown to the dried object or the like. And
The material to be dried is dried, and then discharged out of the machine through an exhaust port.

Therefore, when the motor is driven in the forward direction, the air outside the machine is fed into the storage from the first blower opening by the operation of the first blow impeller, and when the motor is driven in the reverse direction, Since the air outside the machine is sent into the storage from the second air outlet by the operation of the second air impeller,
By alternately repeating the forward or reverse driving of the electric motor, air flows in two directions can be generated alternately in the storage. Therefore, the air heated by the heating element can be uniformly supplied to the storage and the object to be dried without bias, and the object to be dried can be dried efficiently and in a short time. In addition, the object to be dried can be uniformly heated and dried without causing a portion where the temperature is excessively reduced.

According to a fourth aspect of the present invention, there is provided a blower which is capable of blowing air even when the motor is rotated forward or reverse by a set of a blower impeller and a blower casing formed in a radial fan shape. At the time of forward rotation of the motor, the outside air pressurized by the blower impeller is introduced into the storage from both the first blower port and the second blower port via the first blower path and the second blower path. Air can be blown, and more air can be blown from the first blow port than the second blow port due to the shape of the blow casing. Also, when the motor is reversed, the outside air pressurized by the blower impeller is stored in both the first blower port and the second blower port via the first blower path and the second blower path. And more air can be blown from the second blow port than the first blow port. Therefore, two sets of air flows can be generated alternately in the storage by the set of the blower impeller and the blower casing, and the heated air can be uniformly supplied to the object to be dried and the storage. . Therefore, the object to be dried can be efficiently dried in a shorter time. Also, there is no need to provide a separate cooling impeller in the motor,
In addition, the motor can be reliably cooled by the air outside the motor regardless of whether the motor is rotating forward or reverse. Further, since the outside air is supplied to the blower impeller through the intake port, the intake path, and the electric motor, the electric motor can be cooled by the outside air regardless of whether the electric motor rotates normally or reversely.

According to a fifth aspect of the present invention, in addition to the fourth aspect of the present invention, a valve is provided in each of the ventilation paths, and ventilation is performed in each path without loss.

According to a sixth aspect of the present invention, the first blower impeller blows air outside the machine into the storage to discharge the air in the storage, and the second blower impeller generates the air in the storage. By circulating, during the normal rotation of the electric motor, the air outside the machine by the first blower impeller is sent to the first blower impeller via the first intake port and the first intake path and is pressurized, The hot air is supplied into the storage via the first blowing path, the first blowing port, and the heating element. Then, the object to be dried is dried and discharged from the exhaust port to the outside of the apparatus. Further, when the electric motor is reversed, the air in the storage is sent to the second airflow impeller via the first air intake port and the second air intake path by the second airflow impeller, and is pressurized. Route,
Warm air is generated through the second air outlet and the heating element, and is supplied again into the storage to dry the object to be dried. Therefore, when the humidity of the air in the storage is high, the electric motor is rotated forward to discharge the high-humidity air in the storage to the outside of the storage, and to heat the low-humidity air outside the storage to store in the storage. To dry the object to be dried. When the humidity of the air in the storage is low, the object to be dried can be dried by reversing the electric motor and circulating the air in the storage while maintaining the high temperature state. Therefore, by repeating normal or reverse rotation of the electric motor, when the air in the storage is high humidity, the high humidity air in the storage is discharged, and the low humidity outside air is heated to dry the object. When the air in the storage is low in humidity, the high-temperature air in the storage can be circulated while being heated and supplied to the object to be dried. Therefore, the object to be dried can be efficiently dried while repeatedly discharging and circulating the air.

According to a seventh aspect of the present invention, in addition to the fourth aspect of the present invention, there is provided a second blow impeller capable of circulating the air in the storage case even when the electric motor rotates forward or reverse. By this, at the time of normal rotation of the electric motor, air outside the machine is sent to the first blower impeller through the first intake port and the first intake path by the first blower impeller and is pressurized,
The hot air is supplied into the storage via the first blowing path, the first blowing port, and the heating element. Then, the object to be dried is dried and discharged from the exhaust port to the outside of the apparatus. At the same time, a part of the air in the storage is sent to the second airflow impeller via the second airflow port and the second airflow path by the second airflow impeller and pressurized, and the second airflow path and It is supplied again into the storage via the second intake port. Further, when the electric motor is reversed, the air in the storage is sent to the second air impeller via the second air inlet and the second air intake path by the second air impeller, and is pressurized. Hot air is generated through the passage, the second air outlet, and the heating element, and is supplied again into the storage to dry the object to be dried. Therefore, when the electric motor rotates forward, a part of the air in the storage is circulated while heating, the rest is discharged outside the machine, and the air outside the machine is newly heated and supplied to the storage to be dried. Can be dried,
When the motor is turned over, the air in the storage is heated and circulated in a high temperature state to dry the object to be dried. Therefore, by repeating the forward or reverse rotation of the electric motor, the air in the storage can be discharged while being circulated, or the high-temperature air can be circulated.
The object to be dried can be dried more efficiently.

According to an eighth aspect of the present invention, in addition to any one of the first to seventh aspects of the present invention, a third air inlet for feeding outside air into the storage is provided, and a first air inlet is provided. The air in the storage is sucked out of the first air intake by the operation of the first blower impeller when the electric motor rotates forward by connecting the first air supply port to the storage and connecting the first air outlet to the outside of the machine. The first air intake path, the first air impeller, the first air path,
The air is discharged to the outside through the first blower, and new outside air is blown into the storage from the third blower. Also,
At the time of reversal of the electric motor, the air in the storage is sent to the second airflow impeller via the second air intake port and the second air intake path by the operation of the second airflow impeller, and is pressurized. It is supplied again into the storage via the route and the second air outlet. Therefore, at the time of forward rotation of the electric motor, the air in the storage is sucked out and discharged, so that almost all the air outside the machine which is sent from the third blower port and heated by the heating element is dried. The air is blown to dry the object to be dried. And other than the material to be dried (for example, the bottom or side of the storage)
It is not heated and dried except for the material to be dried. Furthermore, even when the air in the storage is hot and humid, the high-temperature and high-humidity air can be reliably discharged from the first blower opening to the outside without leaking from a seal portion such as a door of the storage.

As described above, when the electric motor rotates in the forward direction, the air inside the storage is sucked out and discharged, so that the air outside the device which is sent in from the third blower port and heated by the heating element to become hot air is stored. Almost all air can be blown to the object to be dried without blowing and drying other than the object to be dried such as a wall surface in the refrigerator, so that heat from the heating element is efficiently supplied to the object to be dried. be able to. Further, even when the air in the storage is hot and humid, the high-temperature and high-humidity air can be reliably discharged from the first blower opening to the outside without leaking out of the device from a seal portion such as a door of the storage.

According to a ninth aspect of the present invention, in addition to the sixth, seventh, or eighth aspect of the present invention, a valve for opening and closing the first air passage is provided, so that the on-off valve is opened when the electric motor rotates forward. And circulate while heating a part of the air in the storage,
The remainder can be discharged outside the machine, and fresh air outside the machine can be supplied into the storage. When the on-off valve is closed, almost all the air in the storage can be circulated while being heated without exhausting the air. Therefore, if the air inside the storage is high humidity, open the on-off valve and circulate some of the high humidity air inside the storage while discharging the rest outside the machine to store the low humidity outside air. Can be sent to storage. And
If the air in the storage is low in humidity, close the on-off valve and turn the motor forward or reverse to change the direction of high-temperature, low-humidity air in the storage during the air circulation process in the storage. It can be heated and circulated while changing. Therefore, when the air in the storage is high in humidity, the high-humidity air can be discharged outside the machine and the low-humidity air can be sent into the storage to dry the object to be dried. When the air has low humidity, the object to be dried can be dried while changing the direction of circulation of the air in the storage during the circulation process.

According to a tenth aspect of the present invention, in addition to the fourth, fifth, sixth, or seventh aspect, a humidity detecting device for detecting the humidity of the air in the storage is provided in the second intake path. Due to the provision, at the time of normal rotation of the electric motor, the air outside the machine is sent to the first blower impeller via the first intake port and the first intake path by the first blower impeller, and is pressurized. Hot air is supplied into the storage via one air passage, the first air outlet, and the heating element. Then, the object to be dried is dried and discharged from the exhaust port to the outside of the apparatus. Further, when the electric motor is reversed, the air in the storage is sent to the second airflow impeller via the first air intake port and the second air intake path by the second airflow impeller, and is pressurized. Hot air is generated through the passage, the second air outlet, and the heating element, and is supplied again into the storage to dry the object to be dried. At this time,
Since the humidity detecting device is provided in the second intake path, it is possible to detect the humidity of the circulating air. Therefore, when the humidity of the air in the storage is low, the electric motor is inverted to circulate while heating the air in the storage to dry the object to be dried, but water droplets attached to the object to be dried evaporate. The case where the humidity of the circulating air is high can be detected by the humidity detecting device. Therefore, the switching of the electric motor between the normal rotation and the reverse rotation can be detected by the humidity detection device, so that the switching between the discharge and circulation of the air in the storage can be efficiently performed.
