BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot air heating apparatus, and more particularly, to a hot dash function for quickly increasing the indoor temperature by controlling the hot air heating capacity at the start of operation to be higher than the capacity at the time of normal operation. The present invention relates to a warm air heating device having:

[0002]

2. Description of the Related Art First, the heating principle of a hot-air heating device will be outlined using an oil fan heater as an example. FIG. 13 and FIG. 14 are schematic diagrams showing a configuration of a petroleum fan heater in the related art. FIG. 13 is a front sectional view, and FIG.
Reference numeral 4 denotes a side sectional view. Referring to FIGS. 13 and 14, a conventional oil fan heater includes a fuel tank 1301 and a fuel pump electromagnetic pump 1.
303, an oil feed pipe 1305, a vaporizer 1307,
It includes a burner 1311 and a combustion chamber 1309.

[0003] First, fuel in a fuel tank 1301 is supplied to an oil supply pipe 1305 by an electromagnetic pump 1303 for fuel pressure supply.
To the vaporizer 1307. Vaporizer 1307
Is heated by a vaporizer heater (not shown) to vaporize the supplied fuel. The fuel is gasified by a carburetor 1307 and then burned by a burner 1311. Due to this combustion, the temperature in the combustion chamber 1309 increases.

The oil fan heater further includes a combustion chamber 13
09 and a blower motor 131 for driving the blower fan 1313
5 is included. When combustion in the combustion chamber 1309 is started, power is supplied to the blower motor 1315 and the combustion chamber
The gas warmed in 9 is blown by fan 1313
The air is blown out of the apparatus as warm air while being mixed with air at room temperature. The discharged warm air warms the indoor air.

[0005] In such a hot-air heating device such as an oil fan heater, in order to obtain a comfortable indoor temperature as soon as possible from the start of the heating operation, at the start of the operation, the hot-air heating capacity is larger than that of the normal operation. In many cases, a so-called hot dash function of performing a heating operation with the ability is added.

[0006] The hot dash function, for example, as shown in Japanese Utility Model Publication No. 62-22465 and Japanese Utility Model Publication No. 2-62252, considers the indoor temperature before the start of operation so that more optimal heating operation can be started. To determine the hot air heating capacity at the start of operation. That is, the temperature in the room is measured, and for a while after the start of the operation, the combustion is performed with a combustion amount larger than the combustion capacity in the normal operation based on the measured value.

Further, as disclosed in Japanese Patent Application Laid-Open Nos. 58-10247 and 2-148318, there is also a technique of setting the heating capacity at the start of operation in consideration of not only the room temperature but also the perceived temperature. Can be seen. In this method, the difference between the room temperature and the sensible temperature is taken into consideration, the sensible temperature is predicted based on the measured room temperature, and the temperature set value set by the user is changed under certain conditions.

[0008]

However, in each of these prior arts, the initial heating capacity is controlled only based on the room temperature. The room temperature on which this is based is often a measurement of a predetermined ambient temperature near the device. Therefore, for example, the temperature of a portion near a cold wall, window, ceiling, or the like, which is greatly affected by radiation from these, is not considered.

In general, the room temperature represented by the ambient temperature in the vicinity of the apparatus does not always coincide with the temperature of a portion near a wall, a window, a ceiling, etc., which is greatly affected by radiation from these. Even if the measured room temperature is the same, for example, if the room was once warmed up by a heating device before, the temperature of walls, windows, ceilings, etc. also increased, and the temperature in the vicinity also increased to the same degree as the room temperature However, when heating for the first time, the temperature of the walls, windows, ceiling, etc. is in a low state, so the radiation from these will cause the nearby temperature to be lower than the measured indoor temperature. .

However, from only the measured room temperature,
The effects of radiation from walls, windows, ceilings and the like cannot be considered. Therefore, in the related art in which control is performed based only on the room temperature, if the measured temperatures are the same, hot dash combustion is performed with the same heating capacity in both cases.

For this reason, in the case where the heating has been performed a while ago, if the operation is started with a high heating capacity, the temperature rise will rise more than necessary, and immediately after the desired room temperature or more. Will be. In consideration of this, when performing the hot dash with the heating capacity at the start of operation slightly reduced, when the heating is performed for the first time, the heating capacity is insufficient and the room temperature becomes satisfactory. Would take a lot of time.

That is, with the same heating capacity, it is naturally predicted that the heating capacity will be excessive or insufficient in one case, and it will be difficult to realize a comfortable room temperature. Furthermore, excess and deficiency of combustion can be said to be inappropriate and uneconomical in terms of energy consumption.

Further, even if the measured room temperature is appropriate, the prior art does not consider the room temperature desired by the user when determining the heating capacity at the start of operation. .

The present invention has been conceived in view of the above circumstances, and a first object of the present invention is to perform appropriate heating capacity control at an early stage of operation by taking into account the use state of a heating device, and An object of the present invention is to provide a hot air heating device that can quickly exert its effects.

Thereby, even if time has passed since the device was previously used, the heating effect can be obtained quickly.

Further, preferably, when the detected temperature of the vaporizer is equal to or higher than the predetermined value A, the determining unit sets the hot air heating capacity at the start of the heating operation to be equal to the capacity at the time of the normal operation.

When the difference between the set room temperature and the detected room temperature is equal to or greater than a predetermined value C, the hot air heating capacity at the start of the heating operation is set to be higher than the capacity at the time of the normal operation according to the difference, The setting unit 2 sets the temperature at the start of the heating operation when the difference between the set room temperature and the detected room temperature is less than the predetermined value C when the detected temperature of the vaporizer is less than the predetermined value B. Set the hot air heating capacity equal to the capacity during normal operation.

Thus, even if a long time has passed since the device was previously used, it is possible to appropriately control the heating capacity in consideration of the user's intention, so that the heating effect can be obtained quickly.

[0025] More preferably, the control unit further includes a third setting unit, wherein the third setting unit is provided when the detected temperature of the vaporizer is equal to or higher than a predetermined value B. Set the hot air heating capacity at the start of the heating operation lower than the setting by.

Thus, even when the apparatus has been used before, it is possible to appropriately control the heating capacity in consideration of the user's intention, and it is possible to suppress wasteful energy consumption.

Preferably, the control unit includes a changing unit for changing the set room temperature based on the detected temperature of the vaporizer, and a canceling unit for canceling the setting change by the changing unit.

Since the temperature set value is changed according to the use condition of the heating device, and the change is released as necessary, appropriate control of the heating capacity can be performed, and the heating effect can be promptly exhibited. Can be.

Preferably, the changing unit includes a first changing unit that changes the set room temperature to be higher by a fixed value when the detected temperature of the vaporizer is lower than the predetermined value D.

If a long time has passed since the device was used before, it is possible to control the heating capacity more appropriately by changing the set room temperature to a higher value, and to obtain the heating effect quickly. it can.

Preferably, the changing unit includes a second changing unit that changes the set room temperature lower by a certain value when the detected temperature of the vaporizer is equal to or higher than the predetermined value D.

In the case where the apparatus has been used for a short time, the set room temperature is changed to a lower temperature, so that more appropriate control of the heating capacity can be performed and unnecessary energy consumption can be suppressed. .

Further, preferably, when the detected room temperature becomes equal to or higher than the set value changed by the changing unit,

Preferably, the canceling unit cancels the setting change by the changing unit after a lapse of a predetermined time from the start of the heating operation.

In a space having a large heat capacity, the room temperature becomes substantially constant after a certain period of time. At that point, by returning to the heating capacity at the time of normal operation, it is possible to maintain the room temperature initially set by the user. .

According to another aspect of the present invention, a warm air heating apparatus includes a room temperature setting section for setting a room temperature, a room temperature detecting section for detecting a room temperature, and a room temperature set based on the set room temperature and the detected room temperature.

According to this, since the relationship between the set room temperature and the detected room temperature is also taken into consideration, at the start of operation,
More detailed and appropriate control of the heating capacity reflecting the user's intention becomes possible.

Preferably, when the difference between the set room temperature and the detected room temperature is equal to or greater than a predetermined value E, the control unit adjusts the hot air heating capacity at the start of the heating operation according to the difference. Set higher than the ability at the time.

Thus, when the room temperature is lower than the temperature set by the user, by appropriately increasing the heating capacity according to the degree, the control can be promptly reflected in the intention of the user.

Preferably, when the difference between the set room temperature and the detected room temperature is less than a predetermined value E, the control unit changes the hot air heating capacity at the start of heating operation to the capacity at normal operation. Set equal to

Thus, when the room temperature is not too low with respect to the temperature set by the user, it is possible to suppress the wasteful energy consumption by making the capacity equal to the capacity during normal operation.

That is, in this case, it is considered that the oil fan heater 4 has not been used before, or even if the oil fan heater 4 has been used, some time has passed since the use was finished. It can be expected that the temperatures of the walls, windows, etc. are also low. Therefore, by changing the indoor temperature setting higher by a certain value, the heating capacity at the start of operation depending on the indoor set temperature is controlled to be considerably higher than in the normal operation.

Subsequently, in step S1013, the room temperature (RT) is detected by the room temperature thermistor 119, and in step S1015, the set temperature, that is, the changed temperature is compared with the detected room temperature (RT ≧). SRT?).

When the detected room temperature is equal to or higher than the changed set temperature, a setting change canceling process is performed in step S1019. That is, the setting change canceling unit 907 cancels the temperature change of the room temperature setting unit whose setting has been changed,
The temperature is returned to the original set temperature set by the user (SRT = S
RT-2-3 ° C). Then, the process proceeds to step S1007, in which a normal room temperature control operation of performing a heating operation based on a difference between the original set temperature (SRT) after the setting change is canceled and the detected room temperature (RT) is performed.

On the other hand, if the detected room temperature does not reach the set temperature after the change in step S1015, the process proceeds to step S1017, and it is determined whether the combustion time has passed a predetermined time, for example, 30 minutes. You. If it has not elapsed, the process returns to step S1013,
If it has elapsed, the process proceeds to the setting change release processing in step S1019.

That is, if the detected room temperature becomes higher than or equal to the set temperature after the change, the setting change canceling process of step S1019 is started. When 30 minutes have elapsed (when the determination in step S1017 is Yes), the processing is automatically started. This is because, in a room having a large heat capacity or the like, the room temperature rises slowly, so that the set temperature after the change is not reached, but the room temperature may be stabilized at a value close to a certain level.

Next, when it is determined in step S1003 that the vaporizer temperature is equal to or higher than a predetermined value, initial combustion is started in step S1005 with the set temperature being kept as it is.

In this case, it is considered that the temperature of the walls, windows and the like in the room has been increased to some extent soon after the oil fan heater 4 has been used before. Therefore, it is necessary to prevent waste of energy consumption due to unnecessarily increasing the heating capacity even at the start of the heating operation.

When the room temperature detected by the room temperature thermistor 119 reaches the set temperature of the room temperature setting section 121 after the operation is started with the hot air heating capacity appropriately set at the start of the operation, the operation is started at the beginning of the operation. The hot dash mode is released, and the normal room temperature control operation is performed in step S1007.

As described above, the oil fan heater 4 detects the temperature of the vaporizer 107 to correct the indoor set temperature after estimating the indoor temperature condition to some extent.
Therefore, it is possible to set an appropriate hot air heating capacity at the start of operation, and the detected room temperature is rising, but hot dash control ends in a state where the person in the room still feels cold. Can be avoided.

<Modification 1> Next, a modification of the oil fan heater 4 according to the fourth embodiment will be described. FIG.
10 is a flowchart illustrating a flow in which the hot air heating capacity of the oil fan heater is controlled in the first modification. As shown in this figure, the flow of processing of the oil fan heater in Modification 1 is the same as that of FIG.
The processing after the judgment result of 1003 is reversed.

That is, in this figure, when the vaporizer temperature detected by the vaporizer thermistor 117 is equal to or higher than a predetermined value, a room temperature setting change process is performed in step S1109. However, FIG.
Unlike the processing in step S1009, the processing in the case where it is considered that it is not long before the oil fan heater has been used previously, the indoor temperature is higher than the set temperature.
The setting is changed by a fixed value, for example, 2 ° C. lower (SRT = SR
T-2 ° C).

Then, in step S1011,
Hot dash combustion is performed based on the detected room temperature and the temperature that has been set lower. Further, in step S1015, when the detected room temperature becomes equal to or higher than the set temperature after the change, that is, the lower set temperature, the setting change is canceled in step S1019. Therefore, waste of energy consumption due to unnecessarily increasing the heating capacity even at the start of the heating operation is prevented.

On the other hand, in step S1003, if the vaporizer temperature detected by the vaporizer thermistor 117 is lower than the predetermined value, the program proceeds to step S10.
At 05, hot dash combustion will be performed based on values from the vaporizer thermistor 117, room temperature thermistor 119 and room temperature setter.

As described above, by detecting the temperature of the vaporizer 107, the indoor temperature can be predicted to some extent and the indoor set temperature can be corrected and changed, thereby preventing waste of energy consumption due to unnecessary hot dash combustion. can do. <Modification 2> In FIGS. 10 and 11, the room temperature change process (steps S1009 and S1009)
1109) is performed at the room temperature (RT) set temperature (S
RT) is either greater than or less than
As shown in FIG. 12, a plurality of types of room temperature change processing may be performed.

That is, as shown in FIG. 12, in step S1003, a plurality of predetermined values, for example, SKT1
And SKT2 are provided (SKT1 <SKT2). If the detected carburetor temperature (KT) is less than the predetermined value SKT1 (KT <SKT1), the indoor temperature set value is changed to a higher value in step S1009. If it is equal to or greater than the predetermined value SKT2 (KT ≧ SKT2), in step S1109, the room temperature set value is changed to a lower value, and the predetermined value SKT is set.
When 1 or more and less than SKT2, (SKT1 ≦ KT <SKT
2) In step S1005, the photo dash combustion may be immediately performed without performing the change processing. By subdividing in this way, a more appropriate heating effect can be expected.

In FIGS. 4, 6, 8 and the like, the detected vaporizer temperature is compared with one predetermined value, but a plurality of predetermined values may be provided. Further, in FIGS. 6 and 8, the difference between the detected room temperature and the set temperature is considered in three stages, but the present invention is not limited to this, and it is possible to divide it into more appropriate stages according to the device. It is.

Although FIGS. 4, 6 and 8 specifically show the hot air heating capacity, the present invention is not limited to this value and is set to a higher or lower capacity. You may.

In FIGS. 5, 7, and 9, the room temperature setting section 121 may be provided in the microcomputer, and the room temperature setting switch may be provided outside.

The embodiment disclosed this time is an example in all respects, and should not be considered as restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
