Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a blow-off device for a blow-off port in a hot-air heater.

Conventional structure and its problems Conventionally, the outlet of a hot-air heater that performs heating by passing hot water through it has a louver in its entirety, and the louver can be rotated up and down to a certain degree. The blowing direction is changed by However, this change is very small, and moreover, air is blown out from the entire outlet. On the other hand, in order to adjust the amount of heat exchanged in the heat exchanger, the amount of heat exchanged by the blower is adjusted by using the strong and weak notches of the blower. will change. That is, when the notch is strong, the distance that the air blown from the outlet reaches is shorter than when the notch is strong, which has the disadvantage of worsening the temperature distribution in the room.

Purpose of the invention The present invention is intended to eliminate the above-mentioned drawbacks of the conventional technology, and aims to reduce the difference in temperature distribution between strong notches and weak notches.

Structure of the Invention In order to achieve the above object, the present invention includes an inlet provided above the front panel, an outlet provided below, an operating section that slides up and down above the front panel, and this operating section. a connecting rod connected to a movable vane provided corresponding to the opening of the air outlet, and a partition plate below the heat exchanger with one end of the movable vane facing the suction port; It has a fulcrum provided as a pivot on the side and a blower provided facing the air outlet. When the air outlet is closed, the blower is set to a weak notch, so that there is not much difference in the distance the air reaches when the blower is set to a strong notch and when it is set to a weak notch.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1 and 2. In the figure, 1 is the main body of the hot air heater, and a front panel 2 is provided on the front. An indoor air inlet 3 is provided above the front panel 2, and an outlet 4 is provided below. Note that 5 is a horizontally elongated opening that forms the air outlet 4 . A blower 7 is provided on one side above the front panel 2.
An operating section 6 is provided which is linked to a strong notch that rotates at high speed and a weak notch that rotates at low speed. Further, the operating portion 6 is provided with a sliding groove 6a.
The handle 8 is guided by the sliding groove 6a and slides up and down. The upper end of the movable wing 10 is pivotally supported by a shaft 14, and the movable wing 10 is provided over the entire length of the opening 5 in such a manner that one end, which is the handle side, can rotate up and down at the positions indicated by the dotted line and the solid line in the figure. ing. The connecting rod 9 is rotatably attached to the handle 8 at its upper end and to one end of the movable wing 10 at its lower end. The operating section 6 houses an electrical equipment section 11 having an intensity changeover switch for switching the rotation speed of the blower 7 between high and low speeds. Further, in the ventilation passage 1a in the main body 1, there is a heat exchanger 12 facing the suction port 3 and through which hot water flows.
has been established. A partition plate 13 is provided below the heat exchanger 12.

In the above configuration, when the blower 7 is operated at high power, the handle 8 of the operating section 6 is placed in the upper position. Then, the movable blade 10 moves to the solid line position via the connecting rod 9, and is fully opened to the outlet 4, which corresponds to the high wind speed due to the strong notch.
This is the blowout width of A.

Next, when operating the blower 7 at a low setting,
Place the handle 8 of the operating section 6 in the lower position. Then, the movable blade 10 moves downward about the shaft 14 via the connecting rod 9 to the dotted line position, and the air outlet 4 is narrowed. Therefore, the width of the air outlet 4 is B, and the blower 7 increases the distance that the air reaches in response to the small wind speed of the weak notch, thereby increasing the air circulation in the room.

Effects of the Invention As is clear from the description of the above embodiments, the present invention has a main body having an inlet and an outlet with a heat exchanger and a blower installed therein, and the outlet has movable blades for adjusting the opening area of the outlet. The movable blades were connected to a connecting rod that was connected to a strength changeover notch that switched the blower between high-speed and low-speed rotation, so that the outlet was fully opened during strong notch operation and closed when it was in weak notch operation. By narrowing the air outlet, the distance that the air reaches indoors can be extended when there is a weak notch.In other words, even when there is a weak notch, the indoor circulation increases, and a good temperature distribution that is almost the same as when it is a strong notch can be obtained. , and with a simple mechanical device,
This exhibits the effect of providing an inexpensive blow-off control device.
