Abstract

PURPOSE:To improve the comfortable property upon room heating by a method wherein signals for changing blow-off air direction and blow-off air amount are outputted to a variable blow-off air direction control means and a variable blow-off air amount control means based on the output of a blow-off temperature detecting means. CONSTITUTION:The device is provided with a variable room heating capacity control means 7, the variable blow-off air direction control means 10, 11, the variable blow-off air amount control means 3, 16 and the blow-off temperature detecting means 9. A control circuit 14 outputs the signals to change the blow-off air direction and the blow- off air amount to said variable blow-off air direction control means 10, 11 and the variable blow-off air amount control means 3, 16. When the blow-off temperature is reduced in case the necessary heating capacity is reduced in the room heating of a house provided with a high heat insulating property or the room heating under a comparatively high atmospheric temperature, the blow-off direction of the air is directed to the outside of a living area and the flow amount is increased, as a result, the comfortable room heating effect, without providing the habitant in the living area with the feeling of cold air and deteriorating of the temperature distribution in the room, may be obtained.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a single room device.

Conventional structure and its problems Conventionally, in order to distribute the indoor temperature in the opposite direction, the blow-out airflow is set at a certain angle according to the position of 1 (y1 dimension).At this time, the airflow is Figure 1 ai/i:
As shown in the figure, since the air enters the living area, it may come into contact with the human body, so if the temperature of the blown air is low, the feeling of cold air is likely to occur. When the heating load is large and therefore the operation is performed at a large capacity and the number of blowouts is high, the feeling of cold air is unlikely to occur. If a device with low capacity is used during LO operation, the blowing temperature will be low, causing a cold feeling. If the air flow rate is reduced when the air outlet temperature rises, as shown in Figure 1, even if the direction of the air flow is set to the angle that provides the best temperature distribution, the reach distance will become smaller. However, the indoor air agitation effect is lost and the temperature distribution deteriorates.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and aims to improve comfort during heating.

Structure of the Invention In order to achieve this object, the present invention provides a variable heating capacity control means, a variable blowout direction control means, a variable blowout air volume control means, a blowout temperature detection means, and an output of the SiJ blowout temperature detection means. 1'? Air blowing direction and blowing air volume according to ml? A control circuit is provided for issuing a signal for changing the blowout air direction to the blowout air direction variable control means and the blowout air volume variable control means.

With this configuration, the air outlet temperature of equipment with a small heating load and a reduced heating capacity of ζ+1 is detected,
When it reaches a certain value 17, it has the effect of directing the direction of the blowing air outside the residential area and increasing the air volume.

DESCRIPTION OF EMBODIMENTS 1 and 10. An embodiment of the present invention will be described with reference to FIGS. 2 to 5.

As shown in FIG. 2, there is a 111-chamber device whistle main body, which has a heat exchange path 2, a blower 3, etc. inside. The first thermistor 4 detects the room l:a, and it is equipped with a control device 7 that controls the rotation speed of the compressor 6 in the outdoor unit 5 based on this output and proportionally controls the heating capacity. There is.

Further, the blowout [718] includes a second thermistor 9 for detecting the blowout temperature, a wind direction control blade 10 as a means for controlling the blowout air direction iTJ, and a step motor 1 for rotating the wind direction control @10f.
1 is provided via a shaft 12.

13 is a control circuit 14 for the blower 3 and the step motor 11
This is a controller with a built-in function.

FIG. 3 shows a block diagram of the control [+71 path 14].

This receives the pressure of the second thermistor 9 that detects the blowout temperature, and the comparator circuit 15 which emits a certain setting 1111 field I is 18, and the output of the comparator circuit 15 controls the fan of the blower 3. Speed of motor 16 and step motor 1
The fan motor control circuit 17 and the step motor control circuit 18 control the rotation angle of the fan motor 16 and the step motor 11, respectively.

] Zu, L! In Sabasei, the operation when there is less than one heating unit will be explained with reference to FIGS. 4 and 5.

FIG. 4 is a flow chart of the operation. When the blowout temperature T is detected by the second thermistor 9 (19),
The comparison circuit 15 compares it with a certain set temperature Tset (20). As a result, each time T is set to T
If it is lower than set, a signal is sent to the fan motor control circuit 17 and the step motor control circuit 18, and the fan motor control circuit 17 increases the rotation speed of the fan motor 16, and the step motor control circuit 18 increases the rotation speed of the step motor 1.
Set the rotation angle of 1 to the angle at which the wind direction control blade 10 is horizontal (outside the habitable area) (21). Conversely, if T≧Tset,
The wind direction is set to 1', and the air volume is set to weak (22).

Figure 5 shows the operation with time of each physical quantity (blowout temperature, indoor temperature, heating capacity, wind direction, air volume). l"
Until Tset is reached, the wind direction is set to horizontal and the airflow is strong, and when Tsetf is exceeded, the airflow is switched to weak direction.When the room temperature approaches the set value Trs, the heating capacity is proportionally controlled.
Keep room temperature constant. As the wall 7AA surrounding the bale rises, the necessary heating capacity gradually decreases, and at the same time the air outlet temperature becomes low and reaches Tset. If this continues, the air will feel cold, so change the wind direction horizontally and set the air volume to a strong setting to maintain a good indoor temperature distribution.

As a result, it is possible to eliminate the feeling of cold air caused by low blowout temperature when the necessary heating capacity is small, such as when heating a well-insulated house or when the outside temperature is relatively high, and also prevents deterioration of indoor temperature distribution. It has the effect of

In addition, although this example describes a device whose heating capacity can be controlled proportionally, the same applies to other devices that control room temperature using Hi-Lo continuous %9 and whose capacity during LO operation is set low. The effect of this can be obtained.

According to the heating device of the present invention, the following effects can be obtained.

a heating capacity variable control means, a blowout air direction variable control means, a blowout air volume variable control means, a blowout temperature detection means, and a signal 'f- for changing the blowout air direction and blowout air volume based on the output of the blowout temperature detection means. Since the configuration includes a variable airflow direction control means and a control circuit for controlling the airflow volume variable control means, it can be used for heating in highly insulated houses,
It has the effect of directing the direction of the blowing air outside the living area and increasing the air volume when the blowing temperature is low and the necessary heating capacity is small, such as when K is relatively high, and as a result, cold air is delivered to the residents in the living area. This provides a comfortable heating effect that does not cause discomfort and does not worsen indoor temperature distribution.
