[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot-air outlet of a heat-storage hot-air blower for performing heating by utilizing heat of both a heater and a heat storage member.

[0002]

2. Description of the Related Art Heretofore, this type of heat storage warm air blower has been configured as shown in FIG. Heat storage member 21 for storing heat
And a high-temperature radiating heater 22 for heating and storing the heat storage member 21 to heat the air to warm air, and a heat storage ventilation passage 23 provided for exchanging heat of the air to warm air with the amount of heat stored in the heat storage member 21.
And a heat insulating member 24 for insulating the heat storage ventilation passage 23,
A blower 25 for sending air into the heat storage ventilation passage 23;
A controller (not shown) for controlling the high-temperature radiating heater 22 and the blower 25; and a partly movable hot air outlet 26 or a fixed rectifying plate 27 having a fixed rectifying plate 27 substantially horizontal or substantially vertical to the floor surface. And a hot air outlet 26 having a combined flow straightening plate (not shown). In the above configuration, when heat is stored in the heat storage member 21, the control unit supplies electricity to the high-temperature radiation heater 22, and the heat storage member 2
1 was heated and stored.

Next, in the hot air heat exchange, the control unit supplies electricity to the high-temperature radiating heater 22 and the blower 25, the air is sent to the heat storage ventilation passage 23 by the blower 25, the air is heated by the heat storage member 21, and the high-temperature radiating heater 22 is also heated. The air was blown out from the hot air outlet 26 having the fixed rectifying plate 27.

When the heat storage member 21 is not storing heat, the air sent to the heat storage ventilation passage 23 by the blower 25 is heated only by the high-temperature radiating heater 22 and is fixed.
7 was blown out from the warm air outlet 26.

SUMMARY OF THE INVENTION However, in a heat storage hot air blower that blows strong hot air to heat a room,
When the current plate is fixed, the direction of the hot air blown out of the hot air outlet cannot be changed, so strong hot air cannot be sent in a specific direction or farther away. There was a problem that efficient heating could not be performed according to the usage situation.

[0006] Further, even if the movable rectifying plate has a movable rectifying plate and the direction of the hot air can be changed, the distance between the adjacent movable rectifying plates is lower than that between the rotating support shafts of the movable rectifying plate on the lower side of the hot air. When the width is reduced, there is a problem that the efficiency of blowing hot air is deteriorated due to a pressure loss or the like. Therefore, in order to reduce the influence of the pressure loss, the distance between the movable rectifying plates must be greatly increased, and the amount of rotation of the movable rectifying plates must be reduced.
The wind direction of the warm air could not be finely controlled.

[0007] Therefore, an object of the present invention is to provide a heat storage hot air blower which can send hot air farther and can efficiently control the direction of fine air flow suitable for use conditions.

[0008]

When storing heat in the heat storage member 1, a control unit (not shown) energizes the high-temperature radiation heater 2 and heats the heat storage member 1 by the radiation heat to store heat. If heat is stored during heating, the control unit supplies electricity to the high-temperature radiating heater 2 and the blower 5 when the heat storage is performed, and the air is sent to the heat storage ventilation passage 3 by the blower 5 to be heated by the heat storage member 1 in which heat is stored. Also, the hot air is heated by the high-temperature radiating heater 2, and the hot air whose direction is regulated by the movable rectifying plate 8 which is rotated is blown out to a range farther from the hot air outlet 6.

When the heat storage member 1 is not storing heat, the air sent to the heat storage ventilation passage 3 by the blower 5 is heated only by the high-temperature radiating heater 2 and is directed by the movable rectifying plates 8 rotated respectively. The regulated hot air is a hot air outlet 6
