Description

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

Conventional technology As shown in FIG. 4, this type of heating device conventionally detects the indoor temperature using a radiant temperature detector 11 and a room temperature detector 12, and determines the optimum temperature for the human body according to the detected indoor radiant temperature. a target temperature setter 13 that calculates a target temperature of the room temperature that should give a sensible temperature;
It consisted of a heating element controller 14 and a heating element 15. Then, a target temperature of the room that should give the human body the optimum sensible temperature is calculated according to the indoor radiant temperature detected by the target temperature setting device 13, and the air conditioner is adjusted based on the difference between the target temperature and the detected room temperature. The heating element 15 was controlled. Further, the signal from the radiant temperature detector 11 is transmitted to the target temperature setting device 13.
The target temperature T' is set as a function of the radiant temperature Tb. Thereafter, the set target temperature T' is compared with the room temperature Ta detected by the room temperature detector 12,
The comparison signal operates the heating element controller 14 to control the heating element 15, thereby controlling the room temperature to a target temperature (Japanese Patent Publication No. 7901/1983).

Problems to be Solved by the Invention However, in the above conventional heating device, only the heating element 15 of the room temperature conditioner is controlled as described above.
There is no configuration that appropriately controls both the amount of heat generated and the amount of air blown, and there is no mention of control operations. Therefore, incorrect setting of the airflow rate may make the indoor thermal environment uncomfortable. For example, if the airflow rate is low, the temperature airflow distribution in the room will be uneven, as shown in Figure 5, and the room temperature as a whole will decrease. There were problems in that the rise was slow, and if the amount of air blown was too large, the air would feel cold, as shown in FIG. This unpleasant situation was especially common when heating started. Note that A in FIGS. 5 and 6 is a heating device installed indoors.

The present invention solves such conventional problems,
The purpose of this is to realize a comfortable heating environment by detecting the sensible temperature in the room and controlling both the heat generation amount and the airflow amount according to the deviation between this sensible temperature and the set temperature. The objective is to improve performance and promote temperature rise.

Means for Solving the Problems In order to achieve the above object, the heating device of the present invention includes a heating element for heating the room, a blower for blowing the heat generated by the heating element into the room, and a heating device for controlling the temperature of the room. An air temperature sensor to detect, a radiant temperature sensor to detect the indoor radiant temperature, a sensible temperature calculation means to calculate the sensible temperature from the signal from the air temperature sensor and the signal from the radiant temperature sensor, and a temperature to set to the desired temperature. a setting means, a deviation calculation means for calculating the deviation between the signal from the sensible temperature calculation means and the signal from the temperature setting means, a timer that operates from the time when the heating operation is started, and a timer that operates from the time when the heating operation is started, and when the deviation is input, A heating element control means having a first control function that determines the amount of heat generated, and an air blowing amount controlling means having a second control function that determines the air blowing amount of the blower when the deviation is input, The heating element control means controls the heat generation amount to the maximum value during the time from the start of operation until the deviation reaches a predetermined set deviation value, and the air blower control means controls the timer to keep the time measured by the timer for a predetermined set time. The air flow rate is controlled based on the second control function until
Moreover, the air flow rate is controlled to the maximum value during the time until the set time is exceeded and the set deviation value is reached.

Function The present invention calculates the sensible temperature from the air temperature and radiation temperatures detected by the air temperature sensor and the radiant temperature sensor, and calculates the deviation between this calculated value and the desired temperature set by the user. During the time it takes for the deviation to reach the set deviation value after the start of operation, the calorific value is set to the maximum value, and for a certain period of time after the start of operation, the amount of air blown is suppressed to improve heating performance, and after this certain period of time has elapsed, The air flow rate is forcibly set to the maximum value until the set deviation value is reached, thereby promoting the temperature rise in the room.

Thereafter, the deviation is input to a predetermined first control function and a second control function, and the amount of heat generated and the amount of air blown are controlled based on the outputs of both of these control functions.

Embodiment A heating device according to an embodiment of the present invention will be described based on the accompanying drawings. FIG. 1 is a block diagram of the heating device. 1 is an air temperature sensor, 2 is a radiant temperature sensor that detects the radiant temperature in the room, 3 is a sensible temperature calculation means that calculates the sensible temperature based on the signals from each of the sensors 1 and 2, and 4 is a temperature sensor that allows the user to adjust the temperature to their liking. Temperature setting means to be set, 5 is temperature setting means 4
deviation calculating means for calculating the deviation between the temperature and the sensible temperature calculating means 3; 6, a timer that measures time at the same time as the start of heating operation; 7, heating element control means for controlling the heating element 9;
8 is a blower control means for controlling the blower 10.

The sensible temperature is determined as follows. That is, the signals from each of the air temperature sensor 1 and the radiation temperature sensor 2 are input to the sensible temperature calculation means 3, and processed based on the following calculation formula (1) to obtain the indoor sensible temperature T.

T=αTa+βTr+r (1) Here, Ta is the signal from temperature sensor 1, Tr
is a signal from the radiant temperature sensor 2, and α, β, and r are constants. Also, the sensible temperature T is compared with a set value T' preset by the temperature setting means 4 by the deviation calculation means 5, and the deviation ΔT=T'-T is calculated. below,
The control operation for the amount of heat generated and the amount of air blown will be described based on FIGS. 2 and 3.

Figure 2 shows the indoor temperature and calorific value from the start of heating,
This figure shows the change in the amount of air blown. Further, FIG. 3 shows the output of the first control function (heat amount) and the output of the second control function (airflow amount) when the deviation ΔT is input. As is clear from FIG. 3, the amount of heat generated and the amount of air blown are uniquely determined by the value of the deviation ΔT. At the start of heating, that is, the deviation △T
is the predetermined first deviation set value △T ₁
If the amount is above, the calorific value is set to the highest value, and the air volume is increased stepwise or continuously from a weak air volume to a strong air volume. In this case, when a predetermined set time t' is reached by a signal from a timer 6 activated by the start of heating, the air flow rate is switched to the highest setting. Deviation △T
is less than or equal to the first deviation setting value △T ₁ and greater than or equal to the predetermined second deviation setting value - △T ₂ , the calorific value is continuously set based on the deviation △T, Further, the amount of air blown is set stepwise or continuously according to the deviation ΔT. When the deviation ΔT is smaller than the second deviation setting value −ΔT ₂ , the heat generation amount and the air blowing amount are each set to the minimum.

Through the above action, the sensible temperature in the room is detected, and both the heat generation amount and the airflow amount are controlled based on the deviation from this sensible temperature and the desired set temperature. Since the amount of air blown is forcibly set to a strong air amount after a certain period of time has elapsed, the ability to take in heat after heating starts is significantly improved, and the room temperature rise is promoted.

Effects of the Invention As described above, the heating device of the present invention provides the following effects.

The sensible temperature in the room is detected, and both the heat generation amount and the airflow amount are controlled based on this sensible temperature and the deviation from the desired set temperature. Immediately after the start of operation, the air flow rate is suppressed for a certain period of time, and after this certain period of time, the air flow rate is forcibly set to the maximum value, which significantly improves the ability to take heat after heating starts, and reduces room temperature rise. promoted. Therefore, a more comfortable heating environment can be achieved than before.
