Description

[Detailed Description of the Invention] This invention relates to a hot air supply device used for drying clothes and bedding, etc., and relates to a safety device in case the heater device becomes overheated.

FIG. 4 shows a specific example of a conventional safety device.

That is, FIG. 4 shows AD-600 manufactured and sold by the applicant.
This figure shows a hot air supply device for a futon dryer, in which a blower and a duct 8 communicating with a blow-out lower are provided inside a main body case 1, and a heater is further disposed within this duct.

A safety device containing a reset-type temperature regulator, a temperature fuse, and other overtemperature rise preventers is fixed to the duct 8 in relation to heat transfer, and the reset button 13 of this safety device is pressed. It penetrates the bottom surface of the main body case 1 and projects outward.

Therefore, in such a conventional structure, in order to reset the safety device after it has been activated, it is necessary to lift the main body and press the reset button 13, which is cumbersome to operate and makes it difficult for the user to locate the reset button. Moreover, if an object is accidentally caught between the device and the case while it is placed on the floor, the reset button will be pressed and the safety device will not function. It had a

This idea was made in view of these conventional problems, and by locating the reset button of the safety device at the bottom of the front of the main body case, it was possible to supply warm air to make the reset operation easier. The purpose is to provide equipment.

This invention will be described below with reference to the illustrated embodiment. Reference numeral 1 denotes a main body case made of synthetic resin, which is constructed by joining two halves of cases A and B.

2 is a blower installed in the center of the back of one case B,
It is separated from the motor 3, fan 4, casing 5, etc.

Reference numeral 6 denotes a heater device installed close to the blower 2, which includes a duct 8 that communicates with the blower outlet at one end and a blowout lower opening at the other end on the side surface of the main body case 1; There is also a heater 9.

However, this heater device is located below the case B and provides a space C above it.

Reference numeral 10 indicates a control switch such as a timer or wattage switch arranged vertically in this space C, reference numeral 11 indicates an operation knob for the corresponding switch arranged on the outer surface of case B, and reference numeral 12 indicates an inner surface of case B and a heater device. This safety device is located between the ducts 6 and 8 and is fixed to the duct so as to be related to heat transfer within the duct, and includes a reset-type temperature controller, a temperature fuse, etc., and an overheat preventer. There is.

Reference numeral 13 denotes a reset button that protrudes from this safety device, and whose tip extends outward through the case B, and is used to restore the function of the safety device by pressing it from the outside once the safety device has been activated. belongs to.

Thus, the case B corresponding to the switch 10 and the heater device 6 is recessed inward from the switch 10 position, that is, halfway from the top of the case, to form a recessed portion 14, and the heater device 6 position, that is, this recess. A bulging portion 15 is formed by bulging outward from the lower part to get as close to the outermost surface of the case as possible, and thereby the operating knob 11
is contained within the concave portion 14 and forms a space between the heater device 6 and the inner surface of the case B, and this space allows the safety device 12 to exist.

Furthermore, due to the formation of the concave portion 14, the switch 10 approaches the inside of the case B by the depth of the concave portion, but this switch portion is a space C corresponding to the thickness of the blower 2, and the concave portion and the space are mutually connected to each other. It is designed to occupy a convenient space.

As mentioned above, this idea places the reset button for the safety device on the front and lower part of the main body case, making it easy to perform the reset operation and preventing the main case from tilting or falling over. This provides a highly safe device, and since the reset button is placed in the recess along with other operating knobs, it is easy for the user to understand, and the space formed by the bulge can be utilized. This has the advantage that a safety device can be installed at the same time, and a compact device can be obtained as a whole.
