Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a waist cooling device used as a forehead-type radiator, and aims to create a comfortable indoor environment by effectively using trout radiation heat.

Conventional radiators using radiation and natural convection, such as panel heaters and panel radiators, do not have sufficient absolute capacity and have the disadvantage that they cannot provide sufficient heating when the heating load is large.

For this reason, radiators have been devised that incorporate heat radiation by forced convection in addition to mirror radiation and natural convection. However, even if we are satisfied with the performance, as shown in the plan view of Figure 1, the area in which the fin radiation heat from the equipment 2 in the room 1 has an effect on the human body is locally 1.5 skin as shown by the diagonal line. For example, if a resident who was within this range moves out of this range, not only will the fin radiation heat from device 2 be wasted, but the human body, which until now was receiving mirror radiation heat, will receive forehead radiation heat. The disadvantage was that they felt the difference in temperature and felt colder. Moreover, if you move from outside the shaded area in FIG. 1 to inside the area, it becomes hot and you have to lower the room temperature setting, which is a hassle. The present invention is intended to eliminate the drawbacks of the above-mentioned secondary structure, and the configuration of one embodiment thereof will be described below with reference to the drawings.

Reference numeral 3 designates the main body of the waist air conditioner, in which a surface heating element 4 for dissipating heat by key radiation and natural convection is provided on the front thereof, and a heat exchanger 5 and a blower 6 for dissipating heat by forced convection are provided inside.

A temperature sensing tube 8 installed near the suction port 7 to detect the room temperature is connected to a thermostat 11 that controls heat radiation by forced convection, and is only activated when the surface heating element 4 is energized by closing the switch 9. , it is assumed that the temperature is slightly heated by a small heater 10 with a capacity of 4.5 mm as a changing means. 12 is a hot air outlet.

The effects will be explained based on the above configuration. Hot air is sent out from the air outlet 12 by the heat exchanger 5 and the blower 6,
During heating by forced convection that sucks low-temperature air from the suction port 7,
The room temperature setting stagnation scale position 3 of the thermostat 11 shown on the axis of FIG. 5 is within the shaded area of FIG. It is assumed that the temperature of the thermosensor at that time is point a in a comfortable condition. In this case, the actual room temperature is the temperature at point b, which intersects the graph A of the temperature sensing tube 8 when the surface heating element 4 is OFF, but the temperature of the temperature sensing tube 8 is the temperature when the switch 9 is closed. Since the small heater 1 is slightly heated by the flow, the surface heating element 4, which is somewhat higher than point b, reaches the set temperature of point a, which intersects graph B of temperature sensing node 8 when ON, and is caused by the forced convection. Controls heat radiation. therefore,
The thermosensitive tube 8 detects a temperature higher than the actual room temperature and operates the thermostat 11 to set the room temperature. However, when this occupant moves to a region outside the room 1 where he is exposed to radiation heat (outside the diagonal line shown in FIG. 1), if he opens the switch 9, the surface heating element 4 is turned off and the small Since the heater 101 is not energized, the temperature sensing tube 8
The temperature becomes equal to the room temperature, and the heat dissipation by the forced convection is controlled only when the actual room temperature rises to point a.

In other words, in this case, it is equivalent to moving the room temperature setting scale of the thermostat from 3 to 4 simply by operating the switch 9 without the resident having to take the trouble to adjust the room temperature setting scale position of the thermostat 11. ing. Furthermore, when the occupant moves from outside the area receiving reflected heat in the room 1 shown by diagonal lines in FIG. I will have to move.

Of course, it goes without saying that the thermostat 11 can be freely set manually according to the resident's preference.

As described above, according to the present invention, it is possible to automatically change the temperature setting of the room temperature with just a switch depending on whether or not the resident is receiving radiation heat, and the radiation heat is also not wasted. You can comfortably cool your lower back without any discomfort.
