Description

[Detailed explanation of the invention] This invention relates to a blower device with all stages of heat exchanger.
It is an object of the present invention to provide a blower device with a heat exchanger having a large heat radiation area.

Embodiment 4 of this invention will be described below with reference to FIGS. 1 to 5. In the figures, reference numeral 1 denotes a casing molded from synthetic resin, which is formed of an upper casing 2 and a lower casing 3.

4 is a suction port provided on the left and right sides of the casing 1, 5 is a filter that covers the suction cap, and 6 is a filter holder that holds the filter fittings, forming an engaging claw 7 and engaging the casing 1.

8 is an upper air outlet provided in the upper casing 2, 9 is a front air outlet provided in the casing 1, 10 is a scroll integrally molded with synthetic resin on the lower casing 3, and 11 is an external measurement of this scroll. The provided screw boss 12 is a metal blade case that is fixed with a screw 13 to the screw boss, and has a motor mounting portion 14 gold that protrudes upward, and an intake port 15 is provided on the circumferential side thereof. A fixing portion 17 having a 16-metre screw hole is provided.

Reference numeral 18 indicates a motor fixedly attached to a motor mounting portion, and reference numeral 19 indicates a blade attached to the shaft of this motor, which is disposed within the scroll 10.

A heat exchanger 20 is formed in a substantially U-shape around the motor 18 and placed in contact with the blade case 12, and includes a series of copper pipes 23 extending from the supply port 21 to the discharge port 22. The fins 24 are arranged in four rows in parallel.
A bent portion 25 is provided at the corner so that the casing 1 does not hit the corner.

26 is a heat insulating material provided between the heat exchanger and the upper casing 2, 27 is a damper that switches between the upper air outlet 8 and the front air outlet 9, and a sliding switching lever provided on the casing. It can be switched at 28.

29 is a spring that holds this switching lever metal in a predetermined position;
0 is a selector switch for the motor 18, and 31 is a handle. In the blower configured as described above, the supply port 2
1 and the discharge port 22, and by flowing muddy water, the heat exchanger 20 is heated up by the IJO, and by turning on the changeover switch 30e, the motor 18 is driven, and the impeller 19 gold rotates, and the heat exchanger 20 is heated indoors. Heat exchanger 20 from air suction port 4
Heat is exchanged through the fins 24, and hot air flows from the intake port 15 into the scroll 10 and is blown out from the front air outlet 9 to heat the interior of the room.

The air is blown upward from the upper air outlet 8 by switching the blowing direction to the damper 21 using the switching lever 28 as shown in FIG.

In order to install the heat exchanger 20 that exchanges heat by circulating water in this way, it is placed on the upper part of the blade case 12 so that it is covered with 18-karat gold, and a heat insulating material of 26-karat gold is provided between the upper casing 2 and the lower casing. Since the heat exchanger 20 is not fixed, deformation due to heat can be avoided, and thermal stress can be reduced.

Further, since the heat exchanger 20 is placed in contact with the metal blade case 12, heat is conducted and the heat radiation area becomes large.

As explained above, this invention has the effect of increasing heat dissipation area and sound by having a blade case made of gold and a heat exchanger being provided in contact with the blade case.

[Brief explanation of the drawing]

Figures 1 to 6 show an example of this invention. Figure 1 is a plan view, Figure 2 is a cross-sectional view of Figure 1, Figure 3 is an exploded perspective view of Figure 1, and Figure 4 is an exploded perspective view of Figure 1. 5 is a perspective view showing the lower casing 3 and the blade case 12 gold, FIG. FIG. In each figure, the same reference numerals represent the same parts; 1 is a casing, 2 is an upper casing, 3 is a lower casing, 12 is a blade case, 18 is a motor, 19 is a blade, and 20 is a heat exchanger.
