Description

The present invention creates a comfortable working environment under the cold head temperature conditions in a desk worker's desk space such as a desk, counter, etc., and flexibly responds to the user's desk movement in the office It is related with the personal heating apparatus of the desk space which can be attached and removed freely.

Radiant heating type heating represented by conventional ceramic heaters and convection heating type heating represented by oil stoves can warm the entire room, but only the temperature of the indoor upper space increases. It did not solve the problem of feeling cold from the feet to the knees when sitting in a chair. In other words, for so-called cold people and women, there is a demand for an efficient and functional heating device that can perform individual and personal heating.

In small offices, the feet are cold, so small electric heaters are used, but direct heat to the feet not only causes burns, but also consumes a lot of power, dries, fan sounds, and wiring cord equipment May cause various problems such as distraction, concentration and heat, clothing burns and fire.

In light of this technical background, Japanese Utility Model Application No. 7-11935 “Wooden Desk” is a prior application technology related to personal individual heating that achieves cold head temperature.
This device is a wooden desk that can effectively warm the entire feet of the desk worker inserted in the foot insertion space during cooling and heating, and can perform the desk work comfortably under the cold head temperature conditions optimal for this. Is to provide.
In this wooden desk, in order to achieve such an object, in particular, a planar heating element that radiates far-infrared rays toward the entire leg inserted into the space is provided on the desk component facing the leg insertion space. It is proposed to be buried.

By the way, in terms of personal individual heating, the present applicant has developed a panel type personal floor heating on an aluminum OA floor (Japanese Patent Laid-Open No. 2005-194740, “Duplex using a planar heating element and a metal floor panel”). Floor heating system "). An object of the present invention is to develop a floor heating apparatus adapted to a free access floor, which is an electric heating type capable of efficiently performing the entire room or partial floor heating.
An electric-heated planar heating element that irradiates far-infrared rays is laid together with a heat insulating material without fixing it, and is covered with a metal floor panel such as aluminum with legs that have a hanging edge so as to cover the planar heating element The structure is surrounded by a thermal space.
The metal floor panels are insulated from each other and insulated from each other, and the metal floor panels are connected to each other with a gap between them, so that the confined heat received from the planar heating element is diffused by conduction heat. It is preventing.
It is possible to perform floor heating that is easy to change for free access floors and that can be personally heated, without causing stress on the flooring material, with high efficiency and energy saving.

Although it is possible to realize the cold head temperature with these known technologies, the efficiency of applying individual heat especially when sitting at the desk and the request to be able to warm the cold hand is further individually, Personal heating in a form suitable for the office is required.

Utility Kaihei 7-11935 "Wooden Desk" Japanese Unexamined Patent Publication No. 2005-194740 “Double Floor Heating Device Using Planar Heating Element and Metal Floor Panel”

As mentioned above, the above-mentioned Japanese Utility Model Publication No. 7-11935 “Wooden Desk” can be individually heated, but it is not sufficient in the following points for use in offices, etc., and the technical value of proposing the present invention There is.

First of all, regarding the utility desk 7-11935 "wooden desk", a sheet heating element that radiates far-infrared rays toward the entire foot inserted in the space is provided on the desk component facing the foot insertion space. “Embedding” means that the object desk and the planar heating element are inseparable.
On the office OA floor, layout changes, desk movements, etc. are frequently performed, so relocation movement must be easy. There are cases where the application is limited if the desk must be transported as it moves.

In other words, the actual Kaihei 7-11935 is an integral type of heating, so there was always the problem of structural limitations with the movement of the desk with respect to the relocation movement of individual heating.
In addition, since it is based on a wooden desk, if it is converted to a normal office metal desk as it is, there is an electromagnetic wave effect and an influence on the personal computer, and the floor is made of different materials, so it is under the desk. Simply dissipating heat to the space is problematic in terms of efficiency.

Next, Japanese Patent Laid-Open No. 2005-194740, “Double Floor Heating Device Using Planar Heating Element and Metal Floor Panel” is an invention by the present applicant, but it is a personal heating floor only around one desk. As described above, it is a full-fledged thing in terms of development of a floor heating system or a heating device capable of performing personal heating at a partial portion of the floor.
It is capable of floor heating, which enables efficient and energy-saving personal heating.

However, since it is floor heating, it is also a fact that construction on a part of the floor requires a little work.
In addition, the introduction of a free access floor that is a double floor as disclosed in Japanese Patent Application Laid-Open No. 2005-194740, with the aim of allowing underfloor wiring and piping to be performed freely only after installing personal computer equipment in an office. It is normal to step on.
In other words, since the installation of OA equipment was a prerequisite, there was an opportunity to implement the invention using a metal floor panel in such places as a desktop work place that does not use personal computer equipment, a reception desk that does not use personal computer equipment, etc. There are some office environments that have not reached the point of view.

In other words, Japanese Patent Laid-Open No. 2005-194740 is a part of floor construction, but it is actually a new construction in an office that is not an OA floor or a workplace / desk site where no OA equipment is installed.
Although it is possible to respond to the desire to approve floor construction and to carry out personal heating easily at low cost, there are environmental limitations when floor construction and construction work are not desired.

On the other hand, for conventional heating appliances such as gas and oil stoves, air pollution due to combustion of gas and oil is unavoidable, and it is excessive heating for use in providing individual heat during cooling. However, particularly in offices where space is at a premium, there were problems such as requiring a large storage space during the off-season.

In summary, the problems of the present invention are: a. Respond flexibly to relocation within the office; b. Can be widely applied to any desk work place without the influence of electromagnetic waves, c. Acts as a heating appliance in a safe and healthy way, d. Nevertheless, storage is not a problem even during off-season, e. The idea is to propose a personal heating device that uses the space under the feet of the feet in the form of parts that can be disassembled and packed compactly.

The present invention is movable and not fixed, and is formed of a thin plate such as aluminum or aluminum alloy, and has a shape corresponding to the space under the desk and is open inside the cabinet whose height is adjustable. This is a personal heating device provided with one or more thermal panels with a built-in sheet heating sheet that radiates far infrared rays.
It is a feature of the present invention that the entire shape is a movable cabinet, protects against electromagnetic waves on the desk, and a safe heating device is arranged in the cabinet.

The cabinet has appropriate strength, but is lightweight and freely portable, and can be personally heated at your feet at any time, easily and easily by inserting or pulling the whole into the desk space of the desk. It becomes a device.
Without moving the desk, only the heating cabinet can be moved to heat any part personally.

Further, as the heating means in the present invention, far-infrared heat is used instead of gas or oil combustion. Far-infrared radiation is generated by a sheet heating sheet. However, since the sheet heating sheet is thin, lightweight and highly durable, it can be freely installed or not installed on each inner surface of the cabinet.
The present invention can arbitrarily change the number of heating elements (in the present invention, the thermal panel) based on the technical idea of “separation of a desk and a heating element”, and further a desk on which a personal heating device is installed. Can also be changed freely.

Furthermore, since the cabinet is separated into five surfaces by separating the surfaces, and can be disassembled and assembled by tightening them with bolts or the like, the storage space is not troubled even during the off-season and it is easy to move.
Moreover, it is also possible to divide only a specific surface and an edge of the surface so as to be foldable.
The cabinet is equipped with an opening to put one foot into, and can be created in a rectangular space, a hemisphere, an L-shaped shape in a plan view, a space under the desk, a unique design space shape, or a top surface shape.

The combination of cabinets and thermal panels that can be freely applied to any office desk greatly contributes to the development of office work.
Because of the simple installation method of inserting and removing the cabinet, it can be carried out without difficulty even by the coldness and female people who are supposed users of the present invention.

Can be flexibly adapted to frequent relocation within the office, regardless of the presence or absence of OA equipment as a prerequisite. Can be used.
In other words, a personal cold foot temperature environment can be created at any office desk, and it is possible to concentrate efficiently on the work without worrying about the coldness and the coldness of women.

In the off season, if the cabinet is foldable, it can be stored in a small space if it is inserted from the space under the desk and the cabinet surfaces are disassembled or folded and stored. And when the heating season comes, you can assemble it and insert it under your desk.
According to the present invention, personal heating can be realized pinpointed on a desk to be carried out without the effort and cost of flooring the OA floor.

Since personal heating according to the present invention can be easily carried out when it is desired to carry out, it is possible to carry out the cooler who feels the effectiveness of the cooler on a daily basis during the cooling season in summer. In this case, since the cabinet is completely stored in the space under the desk, the fact that the feet are heated is not known to other people. It provides a reasonably efficient seating activity area for your own personal cold head temperature, and does not give you the uncomfortable feeling that the nearby desk uses heating despite midsummer.

In addition, as a heating means, a thermal panel that incorporates a sheet heating sheet that emits far-infrared rays centering on 9,8 microns is used, but the effect is
a. There is no risk of fire or burns because it is not heated.
b. Since the wind does not blow up from the feet, the nose dries and the skin / skin (face) does not dry. No throat hurts.
c. Relieve knee pain.
d. Eliminate shoe odor.
e. Heat radiates to the surface evenly and is efficiently transmitted to the surface below the knee.
f. The sheet heating sheet is made of an aluminum alloy or aluminum cabinet and shields electromagnetic waves and the like, so there is no influence on the electronic device on the desk.
Etc.

As described above, according to the present invention, it is possible not only to solve the various problems that the electric stove and the like have, but also to prevent the conventional heating without being restricted by the structural limit and environmental limit of the above-described known technology. A personal heating environment can be created in any space lacking in the device.
The far-infrared heating that is easily absorbed by the body effectively eliminates the coldness of the feet and knees and achieves the cold head temperature by utilizing the health, safety and clean nature of far-infrared rays. Quiet heating is possible because it does not emit sound.
Here, a personal heating device with sufficient heating effect, convenience, safety and functionality has been realized.
