有毒な一酸化炭素等を発生する危険を有していた。Problems to be Solved by the Invention However, in the conventional configuration, when the intake air 0.10 closes the vicinity of the entrance 10 of the air passages 2a and 3a with a curtain etc., the air flows from the upper part of the intake port 10 to the rear heat shield plate. However, since the wind resistance is larger in the air path 2a than in the 3m air path, the amount of air in the 2m air path is smaller than that in the 3m path, and the flame of the burner is blocked by the rear shield. If incomplete combustion occurs on the hot plate 2 side or the flame comes into contact with the rear heat shield plate 2,
There was a risk of generating toxic carbon monoxide, etc.

This is a rear heat shield plate provided with a protrusion 2C that guides auxiliary air to the flame of the combustion burner 1, and is erected at the rear of the combustion burner 1. Reference numeral 3 denotes an abbreviated lower heat shield plate provided over the lower part and front part of the combustion burner 1, and has a protrusion 2b on the front side opposite to the protrusion 2C. 4 is an upper heat shield plate, and the combustion chamber 1- formed by the rear and lower heat shield plates 2.3.
The upper opening is covered, and gaps A and 8 are formed in the front and rear. 5 is the heat shield plate, and upper and lower heat shield plates 3.4
There are five wind channels formed between the two. A heat exchanger is constituted by each of the heat shield plates 2 to 5, and the external air taken in is warmed while passing through the heat exchanger. Further, the auxiliary air port 2b is located at a height substantially equal to the height of the flame hole of the combustion burner 1, and is formed as a small-area opening such as a slit. 6 is a convection fan, 7 is a fan case, 8 is a main body case, 9 is an intake filter, 10 is an intake port, and 11 is an air outlet.

ある。The operation in the above configuration will be explained. While the hot air heater is in operation, the entrances 10 of the air channels 2a and 3a are closed by curtains, etc.
Even if the vicinity of the air passage 2m is blocked, the resistance of the air passage 2a becomes large, and the amount of air passing through the air passage 2m becomes smaller than the amount of air passing through the air passage 3a, the air is sucked in from the upper part of the intake port 10, The air guided between the rear heat shield plate 2 and the filter 9 passes through the auxiliary air opening 2b provided in the rear heat shield plate 2 and reaches the protrusion 2c.
The air is supplied to the flame of the combustion burner 1 along the lines to compensate for the lack of combustion air and imbalance, and to prevent incomplete combustion caused by blockages. Incidentally, since air is taken in from the auxiliary air port 2b not only when the combustion chamber is closed, but also during normal operation, the length of the flame of the combustion burner 1 is shortened, and the combustion performance can also be improved.

向上することができるものである。Effects of the Invention As is clear from the examples, the present invention provides an auxiliary air port in the rear heat shield near the intake port, and the combustion performance under normal conditions can be improved by the air flowing in from the auxiliary air port. Of course, incomplete combustion can be prevented even when the intake port is partially blocked, and the safety of the combustion type hot air heater can be improved.
