Description

[Detailed explanation of the idea] <Technical field> The present invention relates to improvement of floor heating equipment.

<Prior Art> The present applicant has developed a hot air generator 1 as shown in FIG.
A part of the warm air is exchanged with heat in the heat exchanger 2 and blown into the room from the louver opening 4 of the front plate by the convection fan 3 attached to the back of the hot air generator 1. The adapter 9 attached to the blower unit 7 is pulled from the air pipe 6 attached to the lower part of the combustion chamber 5 before the air is blown into the room from the louver opening 4 by the rotation of the Sirotskov fan 8 in the blower unit 7. A large number of warm air blowing holes 10a, 10 are provided around the
The blower unit 7 has a structure in which hot air is sent into the hollow hot air mat 11 having the above,
It is designed to be able to be freely attached and detached from the hot air generator 1 and the hot air mat 11, and can be used alone as well as the blower unit 7.
separately proposed a floor heating device configured to be linked to the hot air thermostat in the hot air generator 1.

However, with the above-mentioned floor heating system, there is a problem that it is not possible to switch freely from the hot air generator alone to the floor heating operation, or vice versa, and there is a space under the blower unit that is larger than that. There were drawbacks such as the necessity of placing the stand 12, which made it impossible to achieve a uniform design, and the lack of a dedicated filter for floor heating, which caused dirt to become clogged in the blower unit and warm air mat.

<Purpose> In view of the above, the present invention provides a floor heating device in which a dedicated filter for floor heating is provided in the hot air generating device to prevent dirt clogging in the hot air mat.

In addition, the present invention has the above-mentioned blower unit and warm air mat, which have an optional function for upgrading the system to floor heating for the above hot air generating device, and each is detachable. To provide a floor heating device that can be used even as a generator alone.

Furthermore, the present invention provides the above-mentioned blower unit with the following features:
A floor heating system that has the function of a "stand" that has traditionally been required to be installed on hot air generators, and whose blower unit dimensions are larger than the external dimensions of the stand that comes with the hot air generator. provide.

<Example> An embodiment of the present invention will be shown below.

FIG. 2 is a perspective view of the blower unit of the present invention, in which 13 is a fan casing 14, a blower motor for driving the fan, 15 is a blower motor mounting angle, and 16 is a hot air tube connected to the air conduit 6. An intake opening, 17 a warm air outlet for floor heating, 18 a dedicated cable for interlocking the blower motor 14 with the hot air thermometer of the hot air generator 1, and 19 an interlocking circuit formed by the above cables. These are floor heating "on/off" switches connected in series, and 20a, 20b, 20c, and 20d are positioning protrusions of the warm air generator arranged at the same pitch as the foot of the warm air generator. be. 21 is
This is a bank-like annular protrusion that is one step higher than the center around the top of the blower unit, and is a mounting base that prevents any dripping from the hot air generator positioned by the positioning protrusion from falling onto the floor. It has a function.

In the above configuration, floor heating is turned on/off during floor heating.
When the switch 19 is turned off, the blower motor 14 stops and the hot air generator starts operating independently.
Conversely, if the floor heating "on/off" switch 19 is turned on while the warm air generator is being used alone, the blower motor 14 will be activated in conjunction with the hot air thermometer (not shown) of the warm air generator. starts rotating, blowing warm air to the hot air mat 11 and performing floor heating operation.

In addition, in the blower unit 7 having the above-mentioned stand function, there is no need to place a so-called "stand" under it, but the pitch and bottom area of the four legs (not shown) attached to the back of the blower unit are , even if the stand that comes with the hot air generator is placed under the blower unit in cases where you do not want to leave footprints of the blower unit on the floor, the external shape will be the same as that of hot air generator 1. As long as the dimensions of the mounting base, the external shape of the blower unit, and the position of the legs of the blower unit are determined so that they do not protrude from below the blower unit, the uniformity of the design will not be disturbed even in the above case.

Next, FIG. 3 is a perspective sectional view of the hot air generator to show the filter mechanism exclusively for floor heating. 6a
is the opening of the wind pipe 6 on the combustion chamber 5 side, and 22
is a shikiri board. 23 is a floor heating filter 24
This is a guide plate when the filter 24 is inserted through the lowermost opening 4a of the louver, and the dimension α is sufficiently larger than the dimension β of the filter 24. 25 is a filter frame, 26 is a filter element, 27
is the filter handle. Filter guide 23
are located so as to surround the opening 6a of the wind pipe, and 2
There is a notch 3a. After the filter is inserted, the filter handle 27 slightly protrudes from the opening 4a at the bottom of the louver.

In the above structure, the heat-exchanged hot air passes through the notch 23a of the filter guide 23,
While being blown into the opening 6a of the wind pipe, the air passes through the element portion 26 of the filter 24 inserted into the filter guide. When the inserted filter is to be taken out, it can be easily taken out by pinching the filter handle 27 and pulling it out.

<Effects> As is clear from the above explanation, according to the present invention, not only can the hot air generator be used for independent heating purposes, but also the special filter for the blower unit for floor heating can be attached to the above blower unit instead of to the blower unit. Since the filter is provided on the hot air generator side and can be taken in and out from the louver opening of the hot air generator, the structure of the blower unit is simplified and the filter can be cleaned easily.

Furthermore, since the blower unit can be used as a stand, a stand dedicated to the conventional hot air generator can be made unnecessary, regardless of whether or not floor heating is performed.
