[Problems to be solved by the invention]
As described above, the conventional indoor unit of a hot water heater performs temperature management by blowing warm air in either the left or right direction by using a plurality of deflecting plates of the outlet device. However, when the direction switching knobs of the plurality of deflection plates located on the right side are moved to the left side and the direction switching knobs of the plurality of deflection plates located on the left side are moved to the right side, the pair of left and right deflection plates are Since they face each other, the blowout range of the warm air coming out from the blowout device becomes very narrow. For this reason, the temperature of the floor surface increases as the temperature of the blown hot air rises, causing a problem of discoloration of the floor surface or deformation of the floor surface.
[0005]
Also, when setting the hot air coming out from the outlet device to blow rightward or leftward, it is troublesome because it is necessary to move the direction switching knobs fixed to the pair of left and right deflection plates, respectively. was there.
[0006]
The present invention has been made to solve the above-described problems. The pair of left and right deflecting plates do not face each other, and the temperature rise of the blown hot air is suppressed to change the color of the floor surface. This is to prevent this. Further, by moving either one of the left and right direction switching knobs, it is possible to blow warm air rightward or leftward by a plurality of deflecting plates.
[0007]

DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1 FIG.
1 to 5 are upper cross-sectional views showing the outlet device of the first embodiment according to the hot water heater of the present invention. In FIG. 1, the same reference numerals as in the conventional example indicate the same or corresponding parts. Reference numeral 11 denotes a belt-like connecting arm that connects a right support arm 13 that supports a plurality of deflection plates 12 arranged on the right side and a left support arm 15 that supports a plurality of deflection plates 14 arranged on the left side. Here, an enlarged top view of the belt-like connecting arm 11 is shown in FIG. In FIG. 2, an elongated through hole C is formed on one side of the belt-like connecting arm 11, and a connecting portion d between the right deflection plate 12 and the right support arm 13 is horizontally disposed at a position of the through hole C. It is locked so that it can reciprocate.
[0010]
In addition, a connection portion e between the left deflection plate 14 and the left support arm 15 is fitted into a hole formed on the other side of the belt-like connecting arm 11. Note that the outward angle between the right deflection plate 12 and the left deflection plate 14 can be increased by setting the horizontal length of the through hole C to be long. This is because the distance that the right support arm 13 and the left support arm 15 reciprocate in the horizontal direction becomes longer, and accordingly the right deflection plate 12 and the left deflection plate 14 are provided on the upper and lower ends of one end thereof. This is because it is greatly inclined with f as a fulcrum.
[0011]
Next, operation | movement of the blower outlet apparatus 5 which has such a structure is demonstrated using FIG. 1 and FIGS. 3-5 together. When the right direction switching knob 16 and the left direction switching knob 17 are positioned substantially vertically, the connecting arm 11, the right support arm 13, and the left support arm 15 are all in a horizontal state as shown in FIG. And it arranges in the central part. The deflection plate 12 arranged on the right side and the deflection plate 14 arranged on the left side are arranged so as to be orthogonal to the connecting arm 11. Thereby, the warm air blown out from the line flow fan 4 flows in the horizontal direction through the blowing plate 6 in a state along the right deflection plate 12 and the left deflection plate 14 arranged in the vertical state.
[0012]
If one of the right direction switching knobs 16 is moved to the left side thereafter, the connecting arm 11, the right support arm 13, and the left support arm 15 are integrated into the right side as shown in FIG. Moving. As a result, the right deflection plate 12 and the left deflection plate 14 are inclined to the upper right with the axis f provided at the upper and lower portions of one end thereof as a fulcrum. Therefore, the warm air blown out from the line flow fan 4 passes through the blowing plate 6 in the state of being inclined along the right deflector plate 12 and the left deflector plate 14 arranged in a state of being tilted upward to the left. It flows.
[0013]
Further, when the other, that is, the left direction switching knob 17 is moved to the right side thereafter, the connecting arm 11, the right support arm 13, and the left support arm 15 are integrated into the left side as shown in FIG. Moving. As a result, the right deflection plate 12 and the left deflection plate 14 are tilted upward to the left with the axis f provided at the upper and lower portions of one end thereof as a fulcrum. Accordingly, the warm air flows in the diagonally right direction through the blowing plate 6 along the right deflection plate 12 and the left deflection plate 14 that are arranged in a state of being inclined to the left.
[0014]
Further, after the left direction switching knob 17 is moved to the right side and the right deflection plate 12 and the left deflection plate 14 are tilted to the left, the left direction switching knob 17 is continuously moved to the left side. 5, the connecting arm 11 and the left support arm 15 move integrally to the right as shown in FIG. 5. As a result, the left deflection plate 14 tilts to the upper right with an axis f provided at the upper and lower portions of one end as a fulcrum. Accordingly, since the right deflection plate 12 and the left deflection plate 14 are positioned so as to face each other, the warm air passes along the deflection plate 6 in a state along both the deflection plates, and is tilted rightward or leftward. The range of warm air that flows in an oblique direction and exits from the blowing plate 6 is expanded.
[0015]
Further, when the right direction switching knob 16 is moved to the right after the right deflection plate 12 and the left deflection plate 14 are inclined to the upper right as shown in FIG. 3, the right support arm 13 is moved. Moves to the left side in a state where one end of the arm extends along the surface of the connecting arm 11. As a result, the right deflection plate 12 tilts upward to the left with the axis f provided at the upper and lower portions of one end as a fulcrum. Accordingly, as described above, the right deflection plate 12 and the left deflection plate 14 are positioned so as to face each other outward, so that the blown hot air passes through the blow plate 6 along these deflection plates. It flows in the right diagonal direction and left diagonal direction.
[0016]
As described above, in the air outlet device having such a configuration, the right support arm 13 and the left support arm 15 are connected by the connection arm 11, and these are integrally reciprocated in the horizontal direction. The plurality of deflecting plates 12 and the plurality of deflecting plates 14 arranged on the left side do not face each other. Therefore, the range of the hot air blown out from the line flow fan 4 is not narrowed, and the temperature rise of the blown hot air can be suppressed to prevent the floor surface from being discolored or deformed. In addition, by moving either one of the left and right direction switching knobs, all the deflecting plates arranged on the left and right can be inclined in the same direction, so that the operation of switching the hot air is very simple. .
[0017]
