Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat storage electric hot air blower for blowing air heated by a heat storage body and a heater.

[0002]

2. Description of the Related Art As a conventional technique, a configuration as shown in FIG. 3 is generally known. That is, the heat storage element 5
An air passage 6 provided by the surface of the heat storage element 5; a blower 4 for blowing indoor air into the air passage 6;
And a quartz tube heater 10 for heating the passing air and heating the regenerator 5 by radiant heat.
Some are provided by providing.

[0003] Further, as a configuration of a quartz tube heater 10, a configuration as shown in FIG. 4 is generally known. That is, there is a type in which the heating wire 8 is provided in the pipe 7 and the surrounding air is heated via the pipe 7 when the heating wire 8 generates heat. (See, for example, JP-A-8-42925)

[0004]

In the above-described conventional configuration, in the configuration shown in FIG. 3, the quartz tube heater 10 heats the surrounding air through the pipe 7 when the heating wire 8 generates heat. However, by passing through the pipe 7, it takes time until heat is transmitted to the air around the pipe 7. Thus, at the start of warming, the air blown into the air passage 6 by the blower 4 is supplied to the quartz tube heater 1.
The air is released from the outlet 3 before being heated by 0, and it takes time until the heated air is released, and at the start of warming, cool air is released.

In addition, since the heating wire 8 is provided in a straight line, the heating wire 8 needs to be elongated together with the pipe 7 in order to increase the amount of heat generated, and the length of the heating wire 8 increases the width. There was a problem.

When the heating wire 9 is exposed without passing through the pipe 7 as shown in FIG. 5, although the air is instantaneously heated, the fixing of the heating wire 9 becomes unstable or the heating wire 9 comes into contact with other parts. As a result, there is a danger of electric shock or the like, so that it is necessary to use some kind of fixing tool or insulating material as shown in FIG. 5, and the structure is complicated, and there is a problem that extra space is required.

[0007]

The present invention has the following configuration to solve the above-mentioned problems.

[0008] That is, a suction port and an air outlet for sucking air from the outside are provided in the case body, a blower is provided inside the suction port of the case case, and the air passage through which the air to be drawn in by the operation of the blower is formed. Provided from the suction port to the outlet, in a heat storage electric hot air blower provided with a heat storage body and a quartz tube heater having a heating wire in the pipe in the middle of the air path, a plurality of the quartz tube heaters are provided side by side, A heating wire was spirally wound around the outside of the plurality of quartz tube heaters via a fixing plate.

Further, the heating wire is helically wound through a plurality of fixing plates so as to be sandwiched outside the quartz tube heater.

Further, a quartz tube type heater having a heating wire in a pipe is provided below the heat storage body.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS With the above-described configuration, the following operations can be obtained.

[0012] A suction port and an air outlet for sucking air from outside are provided in the case body, a blower is provided inside the suction port of the case case, and the air passage through which the air to be drawn in by the operation of the blower is connected to the suction port. In the heat storage electric hot air blower provided with a heat storage body and a quartz tube type heater having a heating wire in the pipe in the middle of the air path, a plurality of the quartz tube type heaters are provided side by side, The heating wire is spirally wound around the outside of the quartz tube heater via a fixing plate, so that air is sucked in from the suction port by the blower, passes through the air path, and passes through the air path. On the way, the heating wire in the pipe generates heat, and the air is heated by the heating wire that is formed by spirally winding a quartz tube heater that transmits heat through the pipe and a fixed plate outside the quartz tube heater through a fixing plate. You. The heating wire, which is spirally wound around the outside of the quartz tube heater via a fixing plate, does not pass through the pipe, so that the blown air is heated instantaneously and sent to the air passage by the blower. The heated air releases air heated by the heating wire from the outlet from the start of warming, and then also releases air heated by the quartz tube heater.

[0013] Further, by forming the heating wire spirally through a plurality of fixing plates so as to be sandwiched outside the quartz tube heater, the length of the heating wire becomes longer than when the heating wire is installed in a straight line.

Next, by providing a fixing plate around the quartz tube heater, the position of the heating wire is fixed, and the possibility of contact with other parts is reduced.
