Description

[Detailed description of the invention] Industrial fields of application The present invention is applicable to gas, oil, 71! Using air as a heat or cold source,
The present invention relates to an air conditioner that can raise (or lower) the set temperature to provide comfortable heating or cooling when the room temperature decreases (or increases) due to external conditions.

Conventional technology As an example of a conventional example, heating will be explained.

Generally, in hot air heaters that use gas, oil, electricity, etc. as a heat source to control room temperature, the room temperature control shown in Figure 5 is one of the most advanced in terms of energy conservation. Generally, in order to heat one room, the set temperature is started high, and then the set temperature is gradually lowered. FIG. 5 shows changes in the set temperature of the warm air heater and changes in the room temperature at that time. Oo is the initial set temperature and is now θ. Assuming 218°C, after T = 30 minutes, the set temperature will be lowered by θ1 = 1°C and then 17°C.
After further T2=30 minutes, 02-1
The state of the solid line in which the set temperature is changed to 16°C, which is lower than 35°C, is set as 35. Hot air heaters generally have a combination of strong twist firing (e.g. 3000 kcalTo) - weak combustion (e.g. 1
200 kcat/h) - Combustion stop (hereinafter Hi-Lo
It is called w -OF F combustion. ) or strong twist firing (for example, 30
00 kcat/h) to weak combustion (e.g. 1000 kcat/h)
As a result of the development of devices that can proportionally control up to (kcal/h) and have an OFF function, it has become possible to follow the changes in room temperature due to changes in the set temperature, as shown by the broken line 36 in Figure 5. .

Problems to be Solved by the Invention However, even in such hot air heaters, problems may occur when it comes to actual room temperature control. That is, in Fig. 5, when the room temperature is almost stable at 16°C at point 37, for example, a large number of people come into the living room from outside.

When the door is opened or when the door is opened for ventilation and air is exchanged, the temperature inside the room drops rapidly.

In this way, when the room is warm in an almost steady state, the room temperature may drop due to external conditions during actual use. Conventionally, even when the room temperature suddenly drops due to the above external conditions, the set temperature remains at 16°C (for example, 3000 kcaj/h to 1000 kcat
Even if the combustion is proportionally controlled up to /h and has an OFF function, the lowest room temperature will be at the point indicated by 38, when the outside temperature is 5°C, the room size is 8 tatami mats, and the window size is 1.8
If you have two mX O,9m units and leave the living room open for 4 minutes, the room temperature may drop to 11°C, depending on the influence of the outside wind. ) For example, 3000kcal/
With a hot air heater that performs proportional combustion up to 1000 kcat/h and has an OFF function, it is difficult to determine the temperature of the room even if the external conditions mentioned above are eliminated and the windows are closed. In other words, even if you start reburning at 39°C, the set temperature remains at 16°C, so as the set temperature approaches, the amount of combustion will decrease, but the heat will be absorbed by the walls of the room, so at 16°C. It took a while to reach the room temperature of °C.

This will cause the temperature in your room to rise more slowly.

Those who entered the room from outside and those who have been in the room for a long time will continue to experience cold conditions.

The present invention solves these conventional problems, and when the room temperature drops due to external conditions when the room temperature is in a nearly steady state, the problem occurs when a person who enters the room from outside or a person who has been in the room The purpose is to provide a warm air heater that prevents people from getting cold.

Means for Solving the Problems The present invention provides a temperature detector for detecting room temperature, a room temperature reading input measuring means for reading the room temperature using the voltage detected by the temperature detector as an input signal, and a setting for determining the set temperature of the room temperature. Setting input signal input determining means for determining input of a setting signal based on a signal, and determining save operation based on a save signal that emits a signal to lower (or increase) the set temperature after a predetermined period of time when a save operation switch is pressed. a set temperature determining means that is determined by the save operation determining means and the setting signal input determining means, a set temperature determining means and a room temperature reading hexagonal measuring means, when the room temperature is lower than an arbitrary set temperature. The set temperature is set by an air conditioner operation microcomputer equipped with a temperature deviation calculation means that returns the set temperature to the original set temperature when a predetermined time has elapsed, and a combustion amount (or cooling amount) output means. The difference between temperature and room temperature is 0
If the temperature exceeds 3℃ and a predetermined period of time has elapsed, the set temperature will be returned to the original set temperature and the combustion amount (or cooling amount) will be calculated. People also have a hard time getting cold or cold.

From this point on, the room temperature will drop rapidly, and H4-Low-OF F
The air conditioner that burns starts to re-combust when it reaches the ON temperature 4 determined by the set temperature diary, but if the room temperature decreases due to external conditions compared to the amount of combustion, the room temperature will decrease as shown by the broken line in the figure. .

The system enters save operation again and lowers the set temperature.

Effects of the Invention As described above, according to the present invention, when a predetermined period of time has passed during which the temperature has decreased (or increased) by 03°C from an arbitrary set temperature during save operation, the set temperature is returned to the original set temperature. Since it is a large area, we can expect the following first-order effects.

(1) When a large number of people enter the room during save operation,
If you open a window for ventilation and the room temperature suddenly drops (or rises), the set temperature will be returned to the original setting, so people who have come from outside or who have been in the room for a while will also be able to open or close the room. I rarely feel sluggishness.

(Takumi) Since the set temperature is returned to the initial temperature, the room temperature can be quickly restored even in proportional combustion (or cooling) or Hi-Low-OFF combustion (or cooling).
