Abstract

PURPOSE:To detect automatically the part of a space corner where the temp. is low, and direct the flow of warm air thereto, by a method wherein, a temp. sensor which detects differences in the space temp., is made to work in conjunc tion with the swing louver provided in the vicinity of a warm air blow off outlet. CONSTITUTION:A radiation sensor 12 installed above a swing louver 6 turns horizontally in conjunction with the swinging movement of the swing louver 6, and detects the temp. difference in the horizontal direction of the space. Other than the radiation sensor 12, swing louver 6 which changes warm air blow off direction, drive motor 7, connecting rod 8, a control apparatus which concentrates warm air flow blow off to a low temp. corner in accordance with the output of the radiation sensor 12 is installed. Thereby, this space heater can automatically detect the part of a space corner where the temp. is low and direct the flow of warm air thereto. Accordingly, irregularity in temp. distribution in the space is eliminated, and the uniform temperature distribution of the space which is comfort to users can be obtained.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hot air heater, and more specifically, the present invention relates to a hot air heater that automatically detects temperature differences in a room and sends hot air intensively toward a cold area. This invention relates to a hot air heater that has a function that can eliminate temperature differences.

[Prior Art] FIG. 4 is a perspective view showing an example of a conventional hot air heater, partially shown in cross section. In the figure, (1) is the outer case;
(2) is an operation panel, and (3) is a hot air outlet. (4
) is a wind tunnel, (5) is a combustor that burns fuel, (6) is a swing louver that is installed near the hot air outlet (3) and performs a swinging motion to change the direction of hot air blowing out.
(7) is a drive motor that drives the swing louver (6);
(8) controls the rotation of the drive motor (7) by swinging the louver (6).
) to make the swing louver (6) swing. Note that (8) is a louver provided at the hot air outlet (3), (1o) is a front panel, and (11) is a bottom plate.

In the conventional hot air heater configured as described above, when fuel is combusted in the combustor (5), the combustion gas is mixed with air sent by a blower fan (not shown) in the wind tunnel (4). The mixture becomes warm air and is sent indoors from the hot air outlet (3). At that time, when the operating switch on the operation panel (2) is pressed, the drive motor (7) rotates, and the rotation is transmitted to the swing louver (5) via the connecting rod (8), causing the swing louver (5) to Make a swinging motion to change the blowing direction of hot air.

[Problems to be Solved by the Invention] In the conventional warm air heater configured as described above, the swing louver (6) only performs a swinging motion at a constant period. Therefore, when there is a temperature difference in the room and it is desired to send warm air to a cold area, it is necessary to manually turn the swing louver operating switch ON-OFF and manually change the direction of the swing louver (6).

The present invention was made in order to solve the above-mentioned problems, and an object of the present invention is to provide a hot air heater that can automatically detect cold areas in a room and concentrate hot air in that direction. That is.

[Means for Solving the Problems] A hot air heater according to the present invention has a swing louver provided near a hot air outlet linked with a sensor that detects a temperature difference in the room.

[Function] Along with the swing louver, the sensor also makes a swing motion to detect the temperature difference in the room, and when the swing louver faces towards the cold area, the swing louver is stopped at that position for a certain period of time according to a command from the control device. Sends warm air concentrated in the direction of the cold area.

[Embodiment of the Invention] FIG. 1 is a perspective view of an embodiment of the invention. Note that the same or equivalent parts as in the conventional example shown in FIG. 4 are given the same reference numerals, and the explanation thereof will be omitted. (12) is a radiation sensor attached to the upper part of the swing louver (8), which rotates horizontally in synchronization with the swing of the swing louver (6), and detects the horizontal temperature difference in the room.

FIG. 2 is a perspective view showing a part of the radiation sensor (12) shown in FIG. 1 in cross section. (13) is a heating element whose electrical resistance value changes depending on its own temperature, and is controlled to maintain a constant temperature. The amount of radiant heat received can be detected.

(]4) is a radiant heat transmission window, (15) is a ventilation hole (15a)
It is a bar with a. In addition, in the present invention, the above-mentioned radiation sensor (12) and a device (
Swing louver (5), drive motor (7), connecting rod (8)
)) In addition to the above, a control device (not shown) is provided for concentrating the blowing direction of warm air in one direction toward the cold part of the room according to the output of the radiation sensor (12).

A detailed explanation of the present invention configured as above is as follows. Note that the combustion and hot air blowing operations of the hot air heater are the same as those in the conventional case shown in FIG. 4, so a description thereof will be omitted. A radiation sensor (12) attached to the swing louver (6) performs a swinging motion together with the swing louver (6). When the radiation sensor (12) detects a cold area in the room, the swing louver (6) moves in that direction according to a command from the control device.
) stops and intensively sends hot air into the cold area for a certain period of time.

Conventional swing louvers blow hot air only at certain intervals even if there is a temperature difference in the room, but with the present invention, the swing louver automatically stops toward the cold area and blows warm air. Since air is blown intensively to the cold area, comfortable and efficient heating is possible.

In addition, although the above explanation shows the case where a directional radiation sensor is used, even when a non-directional radiation sensor is used, the radiation sensor (12) can be used as shown in FIG.
fixed, attach a cover (16) to the incident area to limit the incident area, and attach the cover (1G) to the swing louver (6).
A similar effect can be obtained by rotating it in conjunction with .

Further, although the above embodiments show a case where a radiation sensor is used as a means for detecting a temperature difference in the room, other sensors may be used as long as they have the same function.

Furthermore, in the above explanation, the present invention was applied to a hot air heater using liquid fuel, but it can also be applied to a hot air heater using gaseous fuel such as city gas. can.

[Effects of the Invention] As is clear from the above explanation, the present invention links a sensor to a swing louver to detect a cold part of the room and intensively send warm air there. It eliminates temperature differences and provides a comfortable room temperature with no temperature fluctuations.
