Abstract

PURPOSE:To enable to eliminate the ignition failure and the exposure of electrical wiring part of the rain water by a structure wherein an exchaust blow-off port is provided on the front surface of an appliance and a cover to cover an inner underside joint between an exhaust top and an exhaust acceptor is also provided and the lower end of the exhaust box is bent forward in near L-shape and further a V-shaped rain water collecting plate to discharge rain water outside is provided on the inner side of the lower front of the appliance. CONSTITUTION:A cover 9 is attached on the lower inside of an exhaust box 4 in order to cover a joint 5 between an exhaust top 3 and the exhaust box 4. In addition, a bent part 4a, which is bent toward a front 1 side, is provided at the lower end of the exhaust box 4. A V-shaped rain water catch plate 10 to discharge rain water outside an appliance is attached on the front 1 below the bent part 4a. Due to the structure as described above, the rain water entered through an exhaust blow-off port 2 scarcely passes through the joint 5 between the exhaust top 3 and the exhaust box 4, because the cover 9 is provided on the lower inside of the exhaust box 4. Even if past through the joint 5, the water flows onto the inside of the front 1 together with the water past through a gap 7 between the front 1 and the exhaust top 3 and along the rain water catch plate 10 so as to be discharged outside the appliance.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to the overall structure of a rainproof device for preventing rain from entering an outdoor water heater or the like.

Conventional configuration and its problems Recently, due to safety and the need to take up a large amount of space in the bathroom,
Additionally, as appliances become more compact, outdoor water heaters equipped with fans are becoming more common.

The problem is that rain can get into the appliance and water can splash on the electrical wiring, or water can splash on the ignition part, causing ignition failure. Therefore, the challenge is to make it resistant to external factors such as rain.

FIG. 1 shows a configuration diagram of a conventional outdoor gas water heater equipped with a fan. In the case of outdoor gas water heaters equipped with fans, the exhaust air is often directed toward the front of the front 1, as shown in the figure. In that case, as shown in Fig. 1, rain that has entered the exhaust outlet 2 will enter the inside of the appliance through the joint 5 between the exhaust top 3 and exhaust receiver 4 and the gap 7 between the front 1 and the exhaust top 3, and the rainwater will There have been problems in that the pilot flame burner section 8 is swamped, causing ignition failure, and water drips into the electrical wiring connection section, causing insulation defects.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and aims to drain rainwater that has entered from the exhaust outlet to the outside of the appliance.

Structure 3 of the Invention In order to achieve the object described in 1 above, the rainproof device of the present invention has a cover that closes the seam between the exhaust top and the exhaust receiver, and a bent portion that is bent at the lower end of the exhaust receiver, and It has a V-shaped rainwater receiving plate on the front that discharges rainwater to the outside of the appliance, and has the effect of discharging rainwater that enters from the exhaust outlet to the outside of the appliance.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described based on the drawings. Second
In the figure, a cover 9 is attached to the lower inner side of the exhaust receiver 4 to close the seam 5 between the exhaust top 3 and the exhaust receiver 4, and a bent portion 4a is bent toward the front 1 side at the lower end of the exhaust receiver 4.
will be established. A V-shaped rainwater receiving plate 10 for discharging rainwater to the outside of the appliance is attached to the lower front 1.

With the above configuration, since the cover 9 is provided on the lower inner side of the exhaust receiver 4, rain that enters from the exhaust Suita mouth 2 is transmitted along the inside of the front 1 along with water that enters from the gap 7 between the exhaust pipe 1 and the exhaust top 3. Rainwater is transmitted through the rainwater receiving plate 10 and drained out of the appliance.

Effects of the Invention As described above, according to the present invention, no matter how heavy the rain falls, water will not get inside the appliance, so it will not cause ignition failure.
This eliminates the problem of water splashing onto the electrical wiring.
