Description

[Detailed explanation of the invention] (a) Industrial application field This invention relates to a desk with an air conditioner that provides individual air conditioning for people working or studying.

(b) Conventional technology Generally, heating and cooling is performed by blowing cold or hot air from an air conditioner towards the entire room, but since the cold air falls and the warm air rises, during cooling, the cold air is distributed near the floor. The problem is that the heat stagnates, causing the feet to become too cold and the upper body not being cooled very much, and conversely, the feet do not get warm when heating the room.

For this reason, instead of heating and cooling the entire room, an individual air conditioner was proposed in which a fan and a heater are built into the desk, and only the fan is operated in the summer, and the fan and heater are operated in the winter. has been done.

Further, Japanese Utility Model Publication No. 60-2510 discloses an individual air conditioner that blows hot or cold air sent from an air conditioning system below or above a desk.

(c) Problems to be solved by the invention In the former individual air conditioner described above, the air outlet is installed below the desk top, so in summer, the air blown from the air outlet is directed towards the desk. Since the air blows only on the lower body of the person who is wearing clothes, and does not blow on the upper body such as the face, the person does not get a cool breeze and is not satisfied. Moreover, especially in the winter when heating with a heater, if the warm air blown from the outlet is weak, there are problems in that the lower body is not evenly warmed, for example, it is difficult to warm the feet even if the knees are warm. On the other hand, if there is strong wind, there is a risk that dust on the floor will be blown up by the wind, which is unfavorable from a sanitary standpoint. Further, since the heater is built into the housing, when servicing or replacing the heater, the housing must be disassembled and the heater must be taken out, which is complicated.

In addition, the latter individual air conditioner required a ventilation pipe to guide hot and cold air from the air conditioning equipment, which required large-scale construction work and had the disadvantage that the desk could not be moved freely.

The present invention provides a desk with an air conditioner that solves this problem.

(d) Means to solve the problem This proposal consists of a panel heater that emits radiant heat into the space below the desk top, an air inlet that sucks air from the back of the desk, and an air inlet that sucks air from the air inlet. The air conditioner is equipped with an air outlet that blows out air above the top plate through a duct, and is attached to the desk.

(E) Effect In the air-conditioned desk of this invention, the panel heater is not energized in the summer and the blower is operated to blow cool air from the back of the desk through the duct onto the upper body of the person sitting facing the desk. It gives you a cool breeze when you put it on.

Also, in winter, the panel heater is turned on, and the lower body of a person sitting at a desk is warmed almost uniformly by the radiant heat emitted from the panel heater.

(F) Example An example of the present invention will be explained based on FIGS. 1 and 2. 1 is a steel office desk having a top plate 18 and drawers 2 on both sides; This is an air conditioner that is integrally provided astride both the drawer parts 2, 2 so as to close the open side surface 4 on the rear side of the desk.

The air conditioner 3 is located on the side surface 4 of the desk 1, and includes a panel heater 6 that emits radiant heat into the space 5 below the top plate 18, and a floor surface 7 provided above the side surface 4 of the desk 1.
The panel heater 6 includes a fan 8 for blowing out cold air above the top plate 18 from an air outlet 12, and a far-infrared heater, an electric heater, or the like is employed as the panel heater 6.

Air suction ports 10 and 11 are provided at the bottom of the ventilation case (duct) 9 containing the fan 8 and the lower part facing the space 5 below the top plate 18, respectively, and the upper part facing above the desk 1 is provided with air inlets 10 and 11, respectively. It is provided with an air outlet 12, and has a built-in damper 13 that alternately opens and closes the air intake ports 10 and 11.

14 is provided in the blow-off grill part 15, and a heating element 6
and a control switch 14 that controls the fan 8 and damper 13.

The air-conditioned desk 18 of the present invention is configured as described above, and in summer, when the entire room is cooled by an air conditioner (not shown), cold air stagnates near the floor surface 7, making it difficult to work at the office desk 1. If person 16 feels uncomfortable, the temperature at his feet is 25℃, while the temperature of his upper body above desk 1 is 26℃, which is a temperature difference of 1.
℃ (confirmed by measuring at the standard desk height of 70 cm), and if you feel lethargic, turn the control switch 14 to the cooling side, the fan 8 will rotate and the damper 13 will be set to the solid line state, and the lower part will be set to the solid line state. The suction port 11 is blocked. Note that at this time, the panel heater 6 is not energized and does not generate heat. With this operation, the cold air stagnant on the back side of the desk 1 on the floor surface 7 is sucked in through the bottom suction port 10 as indicated by the solid arrow. Then, this cold air is blown out from the air outlet 12 in a forward direction (toward the top plate) by the wind direction changing blade 17, and is blown onto the upper body.

For this reason, the upper body of person 1 above desk 1 is cooled down.
6 allows you to enjoy a comfortable cooling sensation. In particular, blow the cold air that is stagnant behind desk 1 onto your upper body.
The inside of the space 5 below the top plate 18 of the desk 1 is prevented from becoming a ventilation path for cold air to prevent the feet from getting too cold.

If your feet get too cold during this cooling operation, operate the control switch 14 to switch the damper 13 to the state indicated by the dashed-dotted line. It is discharged from 5. The discharged cold air is blown from the air outlet 12 to the upper body. This can relieve the feeling of your feet being too cold.

Also, in the winter, even if the entire room is heated by an air-conditioner (not shown), the person 16 working at desk 1 feels uncomfortable, even though the temperature above desk 1 is 22.7°C. On the other hand, there is a temperature difference of 20℃ underfoot.
If you feel cold in your knees or feet because the temperature is 2.7°C (confirmed by measuring at the standard desk height of 70cm), turn the control switch 14 to the heating side and the panel heater 6 will be energized. At this time, fan 8 is not operated. Through this operation, radiant heat is emitted from the inner wall surface 6a of the panel heater 6 to the space 5 below the top plate 18, and the knees and feet are warmed almost uniformly, and the temperature in the space 5 rises, causing the space 5 above the desk 1 and You can enjoy a comfortable heating feeling that eliminates temperature differences.

Also, if heating the entire room is not enough and you feel cold all over your body, operate the control switch 14 to operate the fan 8 and turn on the damper 13.
When set to the solid line state, the air rising along the outer wall surface 6b of the panel heater 6 as indicated by the solid line arrow is heated by the outer wall surface 6b, and warm air is blown onto the upper body from the air outlet 12.
The radiant heat emitted from the inner wall surface 6a of the panel heater 6 warms the body from the knees to the feet substantially uniformly, thereby heating the whole body substantially uniformly.

In addition, in the above embodiment, cold air or warm air is always
If blowing on the upper body causes discomfort, it is preferable to start and stop the fan 8 intermittently.

Figure 3 shows an example of installing an air conditioner 3 into a ready-made desk 1.
Figure 4 shows an example in which the blow-off grille 15 has a bellows structure and automatically changes the blow-out direction to intermittently blow cool air or warm air onto the person 16, thereby eliminating the discomfort caused by constant exposure to cold air or warm air. The same reference numerals as in FIG. 2 are used to omit the explanation.

(g) Effects of the invention According to this invention, the lower body of a person sitting at a desk in winter can be warmed almost uniformly by the far-infrared radiant heat emitted from the panel heater in the space below the tabletop. Moreover, since heating is not performed by blowing hot air, dust on the floor does not fly up. Moreover, since the panel heater is exposed in the space below the top plate, service inspection of the heater can be easily performed.

In addition, during the summer season other than the winter season, the cool air around the desk is blown onto the upper body of the person sitting facing the desk, thereby ensuring that the person sitting at the desk feels a cool breeze. In addition, since the area near the feet (the space below the desk top) is prevented from becoming a ventilation path for cold air, it is possible to prevent the feet of the person sitting at the desk from getting too cold.
