Description

  The present invention relates to a desk having an air-conditioning function capable of locally operating an air-conditioning function only in a portion where a seat exists without air-conditioning the entire room at a uniform temperature in a space such as an office.

  Conventionally, in a space such as an office, it feels cool in the summer, warm in the winter, and the air conditioner is operated throughout the room in order to obtain a uniform room temperature. Requires energy. In recent years, with the emphasis on environmental problems, in order to save even a little useless energy, an invention that uses air conditioning locally has been made, for example, there are inventions described in Patent Documents 1 to 4.

  Patent Document 1 includes a side plate, a top plate, and a bottom plate. At least one of the side plates is provided with a suction opening, and the top plate is provided with a blow-off opening. The air-conditioning partition apparatus provided with the ventilation fan arrange | positioned between the parts is described.

  In Patent Document 2, a desk having an air conditioner unit for local air conditioning, a human body detection unit for detecting whether or not a person is present in front of the desk, and a signal from the human body detection unit, There is described a personal air conditioner having a control unit that operates the air conditioner unit only when there is a person, and a switch that turns on and off the power supplied to the air conditioner unit, the human body detection unit, and the control unit. Yes.

  In Patent Document 3, an air-conditioning wind blower equipped with an air outlet that introduces air-conditioning air flowing under the floor and blows it into the room is provided with a suction port and a fan for sucking room air into the desk, and sucked from the same suction port. There is described an air-conditioning wind blower provided with a damper that mixes and adjusts indoor air and the air-conditioned air to an arbitrary mixing ratio and blows out from the air outlet.

  In Patent Document 4, the side plate and the top plate inside the side, back and top of the desk are configured to be hollow, and the side plate and the hollow portion in the top plate communicate with each other, and the air supply port and the exhaust port are connected to each other. An air-conditioning / heating desk is provided in which the air supply port is connected to an air supply pipe or the like for supplying cooling / warming air from a heat exchanger.

Japanese Patent Laid-Open No. 06-249494 Japanese Patent Laid-Open No. 02-146451 Japanese Utility Model Publication No. 04-051240 Japanese Patent Laid-Open No. 04-036837

  The air-conditioning partition device described in Patent Document 1 is a device for eliminating non-uniformity (cold air / warm air retention) when the desk is air-conditioned, and a blower fan is provided between the suction opening and the blow-off opening. Although provided, power energy is required to operate the blower fan, which does not contribute to energy saving.

  Moreover, it is a device for eliminating non-uniformity (cold air / warm air retention) when air-conditioning around the desk. The personal air conditioner described in Patent Document 2 is also an air-conditioner in which a heat exchanger and a blower are built in the desk. Since the machine part is provided, not only power energy is required, but also a space for providing an air conditioner part is required.

  Since the air-conditioning wind blower described in Patent Document 3 is provided with a fan, it requires power energy as in Patent Document 1. Also, adjusting the air volume ratio between the indoor air drawn from the inlet and the conditioned air taken from under the floor according to the opening of the installed damper, and determining the air temperature to blow out, it is complicated to adjust to an appropriate air temperature However, it is difficult to air-condition according to individual needs.

  Patent Document 4 is an air-conditioning / heating desk that uses only radiation that is not expected to transfer heat, but because the top plate is also hollow, the surface of the desk that comes into contact with human skin is also affected by radiation and conduction heat. It is extremely uncomfortable that the desk surface gets cold in summer.

  Even in the winter, the human body temperature is about 36 ° C., so if the desk top surface does not exceed 36 ° C., it cannot be recognized as warm, and it is predicted that the human body will feel cold. In addition, it is obvious that the cooling / heating function cannot be sufficiently exhibited due to the lack of heat amount only by radiant heat without heat transfer.

  The present invention is intended to solve the above-described problems in the prior art, and in a space such as an office, the air-conditioning function is reliably exhibited locally rather than uniformly air-conditioning the entire room. An object of the present invention is to provide a desk having an air conditioning function.

  The invention according to claim 1 of the present application is a desk in which a hollow metal partition wall is integrated with both sleeves of the top plate, and the lower end portion of the partition wall communicates with an air conditioning duct for cooling and heating under the floor. By providing a blower outlet at the upper end, the inside of the partition wall is used as a part of the air conditioning wind guide, and by the radiant heat from the partition wall surface made of metal and the cold air or hot air coming out of the blower outlet It is characterized in that the vicinity of the desk is intensively cooled and heated with the transmitted heat.

  By making the partition wall hollow metal, the temperature of the air-conditioning wind flowing from under the floor is immediately transmitted to the partition wall itself, cooled by cold air in the summer, and radiated from the partition wall surface warmed by the warm air in the winter Can be obtained.

  Since an air outlet is provided at the upper end of the partition wall, after the conditioned air flowing from under the floor is used for the above radiant effect, the temperature of the cold air or hot air is still reduced by discharging the conditioned air with sufficient capacity. It is transmitted to the vicinity of the desk.

  Therefore, the air-conditioning effect can be concentrated on the space near the desk by the radiant heat from the partition wall surface and the heat transmitted from the conditioned air from the air outlet.

  These functions eliminate the need to apply air conditioning to the entire room as in the past. Or even when air-conditioning, the indoor temperature can be set to a higher temperature in the summer and lower in the winter compared to the conventional set temperature, creating a comfortable environment with a cooling and heating effect only for the vicinity of the desk. Can contribute and greatly contribute to energy saving.

  In addition, the conditioned air originally supplied into the room with the motive energy of the air conditioner is taken in from below the partition wall, passes through the interior of the partition wall, and is discharged from the outlet at the top of the partition wall. There is no need to provide a fan (for example, a blower fan), and no additional additional power energy is used. Again, this point contributes to energy saving.

  The invention according to claim 2 of the present application is characterized in that in the desk having an air conditioning function according to claim 1, an air volume adjusting means for adjusting the air volume from the air outlet is provided at the air outlet. It is.

  For example, if the air volume adjusting means is provided at the blower outlet portion at the upper end of the partition wall so as to adjust the blowout volume, it is possible to increase or decrease the air-conditioning airflow passing through the inside of the partition wall and the airflow coming from the blowout opening. In addition, the amount of heat transmitted by the radiant heat from the partition wall surface and the conditioned air from the air outlet is adjusted at the same time. That is, this operation adjusts the temperature of the space near the desk.

  Also, when the air conditioning effect is not required, such as when you are away from the seat, if you close the air outlet, the wind from the air outlet will approach 0 and the air conditioning air into the partition wall will be significantly reduced. Get closer to.

  The invention according to claim 3 of the present application is characterized in that, in the desk having the air conditioning function according to claim 1 or 2, a wind direction adjusting means for adjusting the wind direction is provided at the outlet.

  Adjusting the direction of the air-conditioning wind by providing wind direction adjustment means at the air outlet, so that the wind directly hits the seat according to the preference of the seat, or conversely, the wind does not hit the seat can do.

  The air volume adjusting means and the wind direction adjusting means can be used in various types and structures that are used at the outlets of existing air-conditioning equipment, and have both functions of air volume adjustment and wind direction adjustment. It is desirable to use it.

  The present invention has the above-described configuration, and the following effects can be obtained.

  (1) By allowing the conditioned air flowing under the floor to pass through the partition walls provided on the sleeves of the top plate and changing the temperature of the partition walls themselves, a radiation effect can be provided near the desk.

  (2) The temperature of the conditioned air can be transmitted to the vicinity of the desk by allowing the conditioned air flowing under the floor to pass through the partition walls provided on both sleeves of the top plate and blow out from the outlet.

  (3) The vicinity of the desk becomes a comfortable space due to the effects of (1) and (2) above.

  (4) This is based on the idea that it is not necessary to keep the entire room in a comfortable state, and there is no need to use an air conditioner such as an air conditioner. Alternatively, even when the air conditioning of the entire room is operated, the cooling set temperature can be set higher than the conventional set temperature or lower than the heating set temperature, and energy consumption can be reliably suppressed.

  (5) Since the air-conditioning air taken in from the lower part of the partition wall is discharged from the outlet at the upper end, no additional power is required as new energy consumption for blowing out.

1 is a perspective view schematically showing an embodiment of a desk having an air conditioning function according to the present invention. It is explanatory drawing which simplified and showed the function of the air volume adjustment means. It is explanatory drawing which simplified and showed the function of the wind direction adjustment means.

  Hereinafter, embodiments of the present invention will be described in detail. Note that the present invention is not limited to the embodiments described below.

  FIG. 1 shows a case in which four desks 1 a, 1 b, 1 c, and 1 d facing each other are integrated and the structure of the present invention is applied to provide an air conditioning function as the air conditioning desk 1.

  The main body portion of the air conditioner 1 according to the present embodiment includes three partition walls 2 that partition parallel directions, two partition walls 3 that partition opposite directions, and four top plates 4.

  The three partition walls 2 are made of a hollow structure by processing a metal such as steel or stainless steel, and the lower end is opened and communicated with an air conditioning duct (not shown) using the OA floor under the floor 11. .

  A horizontally long air outlet 5 is provided at the upper end of the partition wall 2. In this example, for the desks 1a and 1b on the front side, the air outlets 5 are formed on the left surface of each partition wall 2 in the figure, and the conditioned air w is blown out in the left direction. As for the desks 1c and 1d on the side, an air outlet 5 is formed on the right side surface (the surface hidden in the perspective view) of each partition wall 2, and the conditioned air w is blown out in the right direction. In addition, from the viewpoint of the seated person, the conditioned air w is blown from the right side to the left side.

  Looking at the flow of cold air for air conditioning (summer) or warm air (winter) sent from the air conditioner responsible for air conditioning of the entire building, cold air or hot air (air conditioning air w) sent from the air conditioner is Through an air conditioning duct (not shown) using an OA floor under the floor 11, the air enters the hollow portion 2 a from the lower end of the partition wall 2, blows out from the blowout port 5 at the upper end portion, and finally, a suction port (illustration) such as a ceiling. (Omitted) or returned to the air conditioner by the ceiling chamber method.

  In such a configuration, in the present invention, the hollow portion 2a of the partition wall 2 is used as a part of the air-conditioning wind guide, and the radiant heat from the surface of the partition wall 2 made of metal and the cold air or hot air from the blowout port 5 are used. The vicinity of the desk can be locally and intensively heated and cooled with the heat transferred by

  In the present embodiment, the two partition walls 3 and the four top plates 4 that partition the facing direction are assumed to be wooden, but these can provide the necessary strength and performance. If there is, the material is not particularly limited.

  Further, depending on the design, the two partition walls 3 partitioning the facing direction can also be used as a part of the air conditioning air guide as a hollow structure made of metal.

  About the blower outlet 5 of the upper end part of the partition wall 2, it is desirable to provide an air volume adjusting means and an air direction adjusting means.

  FIG. 2 is a simplified illustration of the function of the air volume adjusting means. The air flow from the air outlet 5 can be opened and closed by operating the open / close state so that the shielding plate 6 covering the horizontally long air outlet 5 can be opened and closed. Can be adjusted.

  That is, if the amount of air to be blown out is adjusted, the amount of air-conditioning air passing through the partition wall 2 and the amount of air coming out from the outlet 5 can be increased or decreased. At this time, the radiant heat from the surface of the partition wall 2 and the amount of heat transmitted by the conditioned air from the outlet 5 are also adjusted at the same time. That is, the temperature of the space near the air conditioner 1 is adjusted by this operation.

  Also, for example, when the air conditioning effect is not required, such as when the user is away from the seat, if the air outlet 5 is closed, the wind from the air outlet approaches 0, and the conditioned air into the partition wall 2 is significantly reduced. The heat transfer also approaches zero.

  FIG. 3 is an explanatory diagram showing the function of the wind direction adjusting means in a simplified manner. By providing the wind direction adjusting means, it is possible to adjust the direction of the conditioned air according to the preference of the occupant.

  If the directional plate 7 is tilted obliquely upward as shown in FIG. 3 (a), the conditioned air blown from the blowout port 5 can be prevented from directly hitting a seated person, while in FIG. 3 (b). Thus, if the direction plate 7 is tilted by 90 ° or more, the conditioned air directly hits the seated person, and a cool feeling (warm feeling in winter) can be given in a short time. Further, the direction plate 7 in FIG. 3 also functions as the shielding plate 6 in FIG.

  As described above, the wind direction adjusting means and the wind direction adjusting means have been described separately as functions, but in actuality, those having both functions of air volume adjustment and wind direction adjustment can be used. Specific examples include louvers such as air conditioners and wings, but there are no particular limitations on the form, structure, and the like.

  The embodiment of FIG. 1 described above is an example in which four desks installed in an office are integrated, but when applied to independent desks, the two desks are applied in parallel or facing each other. The basic idea is the same when a large number of desks are integrated.
