Description

  The present invention relates to a heating device having an air cleaning function.

A heating device having an air cleaning function in which an air purifier and a heating device are combined has been developed to improve convenience. Heating devices that have an air cleaning function often serve as both a heating air blower and a cleaning air blower. However, if the amount of heating air blown is increased or decreased, the amount of purified air blown accordingly increases. It is not possible to set the amount of blowout separately. In view of this, a type in which a heating air blower and a cleaning air blower are separately provided has been developed. In a heating apparatus of a type in which a blower for heating air and a blower for cleaning air are separately provided, the heating function and the air cleaning function can be used independently or simultaneously. For example, Patent Document 1 discloses a heating with an air cleaning function in which an air inlet for a heating device and an air inlet for an air purifier are separately provided, and an air passage for heating air and an air passage for cleaning air are completely independent. An apparatus is disclosed.
Japanese Patent Laid-Open No. 11-23063

Considering the downsizing of the heating device with an air cleaning function, it is advantageous to provide the intake ports of the heating device and the air purifier at positions adjacent to each other as much as possible, rather than providing them at positions apart from each other. is there. Furthermore, in consideration of reducing the burden of maintenance and management of the air filter, it is advantageous to share one intake port.
An air filter is installed at the air inlet, and if a heating device with an air cleaning function is used, foreign matter is trapped in the air filter and the air filter is unavoidably clogged. When the air filter becomes clogged, the air volume for the heating device and the air volume for the air cleaner are insufficient.
Whether the air intake of the heating device and the air cleaner are adjacent to each other or when one air intake is shared, if the heating device and the air purifier are used at the same time, supply of air necessary for the heating device The amount can be affected by the amount of air supplied to the air cleaner. In consideration of this, even if the air cleaning function and the heating function are used at the same time or only one of them is used, an appropriate amount of air is always secured for the heating device. Therefore, it is necessary to secure an appropriate amount of flow.
However, even if the air cleaning function and the heating function are used at the same time or only one of them is used against the phenomenon that the air filter becomes clogged by the use of the device, the air purifier is always used. It is not easy to secure an appropriate amount for the heating device and an appropriate amount for the heating device. If the air filter is clogged and the air purification function and the heating function are used at the same time so that the amount of air for the heating device does not become insufficient, the fan will be operated beyond the capacity of the fan, and the fan with a higher capacity Is required. A large-capacity blower increases power consumption and increases operating noise, and also makes it impossible to downsize the entire apparatus.
When the air intake of the heating device and the air cleaner are placed adjacent to each other, or when a single air intake is shared, the overall size of the equipment is reduced, so that power consumption and operating noise are kept to an appropriate level. When the air cleaning function and the heating function are used at the same time, the amount of air for the heating device tends to be insufficient. When the air filter is slightly clogged, the amount of air for the heating device may be insufficient and heating operation may not be possible.
In the present invention, while using a blower that can suppress power consumption and operating noise to an appropriate value, the amount of air for heating does not become insufficient as long as the air filter is slightly clogged. Realize technology that enables continuous operation.

In this invention, the air blower of the grade which can suppress power consumption and driving | running noise to an appropriate value is used. If the air filter is clean, this blower supplies air necessary for the heating operation to the heating device when the air purification function and the heating function are used at the same time, and cleans the air necessary for the air purification operation. Can be supplied to the machine. However, since the power consumption and operating noise are controlled to appropriate values, there is no margin in the ventilation capacity, and if the air filter becomes slightly soiled, the air supplied to the heating device when the air cleaning function and the heating function are used simultaneously Insufficient quantity and possible incomplete combustion. In this case, normally, the heating operation must be forcibly stopped. In the present invention, the heating operation need not be stopped as long as the air filter is slightly soiled, and the continuous operation can be performed. Therefore, in the present invention, if the air filter is slightly soiled and the air cleaning function and the heating function are used at the same time, the air cleaning operation is forcibly stopped when the amount of air supplied to the heating device is insufficient. Then, the air supplied to the air purifier can be supplied to the heating device, and the heating operation can be continued.
When the air filter becomes further dirty, the amount of air supplied to the heating device is insufficient even when only the heating operation is performed. The present invention cannot solve this problem. The present invention realizes a heating apparatus that can continue the heating operation as long as the air filter is slightly soiled, and can continue the heating operation until it is severely soiled.

(One way to solve the problem)
A heating apparatus having an air cleaning function according to the present invention includes a burner that burns fuel, a combustion state monitoring device that monitors the combustion state of the burner, and sucks air from a common intake port and supplies the air to the burner. A first blower that blows heated hot air from the hot air outlet, an air purifying unit that purifies the air, and aspirating air from a common intake port and supplying the air to the air purifying unit and by the air purifying unit The 2nd air blower which blows off the purified air from the purified air blower outlet is provided. Furthermore, it is provided with control means for lowering the operation level of the second blower until the incomplete combustion state is resolved when the incomplete combustion state is determined by the combustion state monitoring device.
The air purifying means here is one that purifies air by passing through a dust collection filter, one that generates sterilization ions and cleans the air with sterilization ions, and passes the dust collection filter and removes it. Various types of air cleaning means are included, such as those that generate bacteria ions to purify the air, or those that generate negative ions to clean the air.
(The action and effect)
In this apparatus, the intake port through which the first blower sucks heating air and the intake port through which the second blower sucks clean air are shared. That is, both the air necessary for burning the fuel and the air necessary for the air cleaning means to clean the air are sucked from the same intake port. When the heating operation and the cleaning operation are performed at the same time, an amount of air necessary for each is sucked from the common intake port.
This apparatus includes means for monitoring the combustion state of a burner that burns fuel and heats air. When the air filter provided at the intake port is slightly clogged and the amount of air sucked from the intake port is reduced, and the combustion state monitoring means determines that the incomplete combustion state is present, the control means operates the second blower. Decrease the level. As a result, the amount of air supplied to the air cleaning means is reduced, the amount of air necessary for the heating means is secured, the incomplete combustion state is eliminated, and the heating operation can be continued.

(One preferred means)
It is preferable that the control means prohibits the operation of the air cleaning means and the second blower when the operation level of the second blower cannot be lowered any more.
(The action and effect)
If the control means can reduce the operation level of the second blower to zero, the entire amount of air sucked from the intake port can be supplied to the heating device, and the range in which the heating operation can be continued is possible. Stretched.

(One preferred means)
It is preferable that a notification means for notifying that the operation of the air cleaning means and the second blower is prohibited is added.
(The action and effect)
Thereby, the user can know that the air cleaning operation is prohibited. In addition, it is possible to know in advance that the air filter is slightly soiled and if it is left unattended, it will eventually become heavily soiled and heating operation cannot be performed.

A first embodiment of a gas fan heater having an air cleaning function embodying the present invention will be described in detail with reference to the drawings.
As shown in FIGS. 1 and 2, the gas fan heater 1 having an air cleaning function of this embodiment includes a main body case 22, an air cleaning unit 10, and a heating unit 50. The air cleaning unit 10 includes an ion generator 4, a sirocco fan (second fan) 8, and a dust collection filter 9. The heating unit 50 includes a combustion case 34 having a gas burner 36 and a hot air fan (first fan) 42.
FIG. 1 schematically shows a front view of the main body case 22 with the front plate removed. The main body case 22 forms an outer frame of the gas fan heater 1. A cleaning air outlet 2 is formed on the upper surface of the main body case 22, a common air inlet 26 for taking in air used for heating and air used for cleaning is formed on the rear surface, and a hot air outlet 44 is formed on the front surface. Is formed. In the upper part, an ion generator 4 and a sirocco fan 8 partitioned by a partition plate 6 are arranged. A combustion case 34 having a gas burner 36 inside is disposed behind the partition plate 32. A thermistor 18 is provided at a position corresponding to the upper portion of the gas burner 36 on the front surface of the partition plate 32. A hot air fan 42 is provided below the combustion case 34, and a hot air outlet 44 is provided in front of it.

  As shown in FIG. 2, a common air filter 24 is detachably provided on the common intake port 26 formed on the back surface of the main body case 22 so as to cover the entire surface. The common air filter 24 is for removing dust in the room, and is formed from a fine mesh made of resin. Air sucked from the common air inlet 26 through the common air filter 24 is sucked into the air cleaning unit 10 and the heating unit 50.

When the gas burner 36 provided in the combustion case 34 of the heating unit 50 is ignited, the combustion secondary air sucked from the common intake port 26 and sucked from the combustion secondary air intake port 28, and the combustion primary (not shown) Fuel gas is combusted by the primary air for combustion sucked from the air suction port. The combustion gas generated by the combustion is discharged from the upper part of the gas burner 36 through the upper part of the combustion case 34.
During combustion, air is continuously sucked from the common intake port 26 by the rotation of the hot air fan 42. As a result, the combustion gas discharged from the upper part of the combustion case 34 and the air sucked from the common intake port 26 are mixed between the partition plate 32 and the combustion case 34 to become mixed air adjusted to a moderate temperature. .
Further, the air sucked from the common intake port 26 by the rotation of the hot air fan 42 flows downward between the main body case 22 and the partition plate 32 to cool the main body case 22, and finally the partition plate 32. The air is sucked into the heating unit 50 from the lower gap and further mixed with the mixed air coming from the upstream side. The mixed air thus mixed becomes warm air having an appropriate temperature for heating.
The hot air is guided to the hot air outlet 44 by the rotation of the hot air fan 42 and blown out from the hot air outlet 44.

  The thermistor 18 is attached to the partition plate 32. The thermistor 18 is mounted at a height corresponding to the upper portion of the gas burner 36. The temperature of the partition plate 32 at a height corresponding to the upper portion of the gas burner 36 varies depending on the combustion state of the gas burner 36. When the combustion state of the gas burner 36 is normal, since the flame does not extend upward because it burns vigorously with a short flame, the periphery of the partition plate 32 at a height corresponding to the upper portion of the gas burner 36 is overheated. There is nothing. The temperature detected by the thermistor 18 is within the normal range. On the other hand, when the gas burner 36 falls into an incomplete combustion state, the flame becomes unstable and extends upward, so that the periphery of the partition plate 32 at a height corresponding to the upper portion of the gas burner 36 is overheated. The temperature detected by the thermistor 18 exceeds the normal range. The thermistor 18 monitors the combustion state of the gas burner 36 through the detected temperature.

  Above the heating unit 50, an air cleaning unit 10 partitioned by a partition plate 6 is disposed. A small sirocco fan 8 is arranged behind the partition plate 6, and an ion generator 4 is arranged on the side surface. A dust collection filter 9 is disposed behind the sirocco fan 8 and the ion generator 4. The rear of the air cleaning unit 10 is open, and air can be sucked from the common air inlet 26.

The air cleaning unit 10 will be described in more detail with reference to the enlarged front view of FIG. 3 and FIG. 4 showing the IV-IV cross section of FIG.
The dust collection filter 9 is provided so as to cover the entire rear surface of the air cleaning unit 10. The dust collection filter 9 collects fine particulate dust that has not been completely removed by the common air filter 24, odor sources, cigarette smoke, and the like, and cleans the air passing therethrough.
The ion generator 4 generates both positive ions and negative ions by applying a high voltage from an AC power supply 66 to the inner electrode 62 and the outer electrode 64 disposed with the cylindrical insulator 60 interposed therebetween.
The sirocco fan 8 incorporates a small motor 8a at the center, and rotates by the rotation of the motor 8a. The sirocco fan 8 sucks air from the common intake port 26 through the dust collection filter 9, and also cleans the air purified by the dust collection filter 9 and the ions generated by the ion generator 4 from the purified air outlet 2. Blow out. The sterilization action of room air is obtained by the interaction between the blown out negative ions and positive ions.

  As shown in FIG. 2, the operation panel 12 on which the user operates the air cleaning unit 10 and the heating unit 50 and the operation of the air cleaning unit 10 and the gas burner 36 are located in front of the upper surface of the main body case 22. A notification lamp 14a that notifies that the air filter has been stopped and a filter lamp 14b that notifies that the air filter needs to be cleaned are provided. A controller 16 that controls the operation of the air cleaning unit 10 and the heating unit 50 is provided inside the main body case 22.

  As shown in FIG. 5, the operation panel 12 is provided with a heating operation switch 12a, an air cleaning operation switch 12b, and a temperature setting switch 12c. The heating operation switch 12a instructs the start and stop of the heating operation performed by the heating unit 50. In the air cleaning operation switch 12b, the start and stop of the air cleaning operation performed by the air cleaning unit 10 are instructed, and the level of the air cleaning operation desired by the user is set. The level of the air cleaning operation will be described later. The temperature setting switch 12c sets the room temperature desired by the user. As the heating operation switch 12a and the air cleaning operation switch 12b are provided separately, the heating operation and the air cleaning operation can be performed separately and independently. Further, the heating operation and the air cleaning operation can be performed simultaneously.

As shown in FIG. 5, the controller 16 is provided with combustion state monitoring means 16a, heating unit control means 16b, air purification unit control means 16c, and display control means 16d.
The combustion state monitoring means 16 a monitors the combustion state of the burner 36 from the temperature detected by the thermistor 18. For this purpose, the combustion state monitoring means 16a stores a threshold value in the normal range of the detected temperature of the thermistor 18 shown in FIG. The threshold value in the normal range is determined as a high threshold value when the level is low and a low threshold value when the level is high, depending on the level of heating operation described later. When the heating operation is performed at a low level, the amount of air at low room temperature sucked from the common intake port 26 is small, and even if the combustion gas is mixed between the partition plate 32 and the combustion case 34, the temperature is lowered so much. It is never done. Since the mixed air that passes in the vicinity of the thermistor 18 is kept at a relatively high temperature and the detected temperature becomes high, it is determined as a high threshold. On the other hand, when the heating operation is performed at a high level, the amount of air at low room temperature sucked from the common intake port 26 is large, and the temperature greatly decreases when the combustion gas is mixed between the partition plate 32 and the combustion case 34. It is done. Since the mixed air that passes in the vicinity of the thermistor 18 has a relatively low temperature and a low detection temperature, it is determined to be a low threshold value. (Note that the mixed air that has moved between the partition plate 32 and the combustion case 34 below the thermistor 18 is heated by the heat release from the burner 36 to an appropriate temperature.) When the detected temperature of the thermistor 18 exceeds the threshold value, It is determined that the partition plate 32 is abnormally overheated and the gas burner 36 is in an incomplete combustion state. If the detected temperature of the thermistor 18 does not exceed the threshold value, it is determined that the gas burner 36 is in a normal combustion state.
The heating unit control means 16 b controls the ignition operation / heating power adjustment / extinguishing operation of the gas burner 36 and the rotational speed of the hot air fan 42. The heating operation level controlled by the heating unit control means 16b is automatically set to 1 according to the temperature difference between the set temperature set by the temperature setting switch 12c and the detected temperature of the room temperature detected by a room temperature sensor (not shown). 7 stages up to 7. Level 8 is a level for forced strong operation at the beginning of heating operation, and is automatically selected when normal operation is started by operating the heating operation switch 12b or when operation is started in timer operation. In accordance with the heating operation level determined in this way, the heating power adjustment of the gas burner 36 and the rotational speed of the hot air fan 42 are controlled. When the level is low, the heating power level is small and the amount of wind is small.・ Large air volume.
The air cleaning unit control means 16 c controls the ion generation operation of the ion generator 4 and the rotational speed of the sirocco fan 8. The air cleaning operation level controlled by the air cleaning unit control means 16c is determined to the level set by the air cleaning operation switch 12b (displayed in three stages of “weak”, “medium”, and “strong”). The ion generation operation of the ion generator 4 and the rotational speed of the sirocco fan 8 are controlled according to the air cleaning operation level determined in this way. When the level is low, a small amount is generated and a small air volume is set. Sometimes it is a large amount of generation and large air volume.
The display control means 16d changes the display of the notification lamp 14a and the filter lamp 14b. When the operation of the air cleaning unit 10 or the heating unit 50 is not started or stopped, the notification lamp 14a is blinked. Further, the filter lamp 14b is blinked in order to prompt the common air filter 24 to be cleaned.

Next, the operation of the gas fan heater 1 having an air cleaning function will be described with reference to the flowchart of FIG. In this flowchart, a procedure mainly for heating operation will be described.
First, when the user turns on the heating operation switch 12a (step S2), the heating unit control means 16b starts the heating operation at level 8. As the temperature difference between the set temperature set by the temperature setting switch 12c and the detected temperature of the room temperature detected by the room temperature sensor gradually decreases, the heating operation level is lowered step by step.
After the heating operation is started, the thermistor 18 constantly detects the temperature. When the combustion state monitoring means 16a acquires the detected temperature (step S4), it is determined whether or not the detected temperature is equal to or lower than the normal range threshold (step S6). If it is below a threshold value, it will transfer to step S18, and if it determines with YES by step S18, heating operation will be continued.

On the other hand, if it is determined in step S6 that the threshold value is exceeded, it is determined in step S8 whether or not an air cleaning operation is being performed. Below, the case where the air purification driving | operation is already performed first is demonstrated. An example of this is shown in FIG. In this example, since the heating operation level is initially high at the time of T1, the threshold value of the normal range of the detected temperature is low, and the heating operation level is lowered stepwise as the set temperature approaches the room temperature. Since the heating operation level becomes constant when the set temperature and the room temperature coincide with each other, the threshold value is also constant. On the other hand, the temperature detected by the thermistor 18 gradually increases from the time point T1, rapidly increases from the time point T2 when the air cleaning operation is started, exceeds the threshold, and reaches the current time point T3. In such a case, YES is determined in step S8, and the process proceeds to step S10.
In step S10, the air cleaning unit control means 16c determines whether or not the air cleaning operation level can be lowered. If the air cleaning operation is being performed at a level other than the lowest level “weak”, the level can be lowered, so that it is determined YES, and the air cleaning operation level is automatically lowered by one step in step S14.
If it determines with continuing heating operation by continuing step S18, it will return to step S4. When the combustion state monitoring means 16a acquires the detected temperature of the thermistor 18 (step S4), it is determined whether or not the detected temperature is below the normal range threshold (step S6), and when it is determined that the threshold is still exceeded. Processing up to step S18 is performed. A series of processing from step S4 to step S18 is repeated, and the air cleaning operation level is automatically lowered step by step.

On the other hand, when it is determined in step S10 that the air cleaning unit control means 16c cannot lower the air cleaning operation level (when the air cleaning operation is performed at the lowest level “weak”), step S12 is performed. Then, the air cleaning operation is stopped, and the display control means 16d flashes the notification lamp 14a and the filter lamp 14b in advance. The notice lamp 14a informs that the air cleaning operation has been stopped by blinking the notice lamp 14a, and the notice lamp blinks the notice lamp 14b that the common air filter 24 is slightly soiled and that the heating operation cannot be performed if it is left as it is.
If it determines with continuing heating operation by continuing step S18, it will return to step S4. Again, the combustion state monitoring means 16a acquires the detected temperature of the thermistor 18 (step S4), determines whether or not the detected temperature is below the normal range threshold (step S6), and determines that it is below the threshold. For example, it is possible to proceed to step S18 and continue only the heating operation.
As described above, the detected temperature that would continue to rise beyond the threshold value as indicated by the broken line 81 in FIG. 8A by lowering the air cleaning operation level or stopping the air cleaning operation. , As shown by a solid line 82. That is, by reducing the amount of air required for the air cleaning operation, the reduced amount can be used for the heating operation, and the incomplete combustion state of the gas burner 36 is eliminated. There is no need to lower the level of heating operation.

On the other hand, after stopping the air cleaning operation in step S12, the process returns from step S18 to step S4, and when it is determined in step S6 that the detected temperature still exceeds the threshold value, NO is determined in step S8. In this case, the process proceeds to step S16. In step S16, the heating unit control means 16b also stops the heating operation, and the display control means 16d causes the notification lamp 14a and the filter lamp 14b to blink. It is possible to notify that the heating operation is stopped by blinking the warning lamp of the notification lamp 14a, and it is possible to inform that the common air filter 24 is severely soiled by blinking the warning lamp of the filter lamp 14b.
As a result, the air cleaning operation and the heating operation are stopped, and the operation of the gas fan heater 1 having the air cleaning function is ended.

Next, a case where the air cleaning operation has not yet been started will be described. An example of this is shown in FIG. In this example, the detected temperature of the thermistor 18 gradually rises after the heating operation is started at the time T1, and reaches the current time at T3. In such a case, NO is determined in step S8 in the first process, and the process proceeds to step S16.
In step S16, the air cleaning unit control means 16c enters the air cleaning operation start disabled mode, and the display control means 16d causes the notification lamp 14a and the filter lamp 14b to blink. In this case, even if the user presses the air cleaning operation switch 12b, the air cleaning operation is not started.
As described above, by making the start of the air cleaning operation impossible, it is possible to avoid the detected temperature from rapidly rising from the solid line 84 to the broken line 83 at time T3 as shown in FIG. 8 (2). The

As described above, according to the present embodiment, by reducing the level of the air cleaning operation, it is possible to continue in a normal state without lowering the level of the heating operation. When the level of the air cleaning operation cannot be lowered, the same effect can be obtained by stopping the cleaning operation.
Moreover, when the air cleaning operation has not yet started when it is determined that the combustion state is incomplete, danger can be avoided by disabling the start of the cleaning operation and stopping the heating operation.

(Second Embodiment) A second embodiment of a gas fan heater having an air cleaning function embodying the present invention will be described below. As shown in FIG. 9, in this embodiment, a thermocouple 19 is provided in the combustion case 34 instead of the thermistor. Since the other configuration is the same as that of the first embodiment, the same reference numerals are assigned and redundant description is omitted.
A thermocouple 19 provided in the combustion case 34 detects the temperature of the flame that changes depending on the combustion state of the gas burner 36. When the combustion state of the gas burner 36 is normal, since the flame temperature is high, the temperature detected by the thermocouple 19 is also within the normal range. On the other hand, when the gas burner 36 falls into an incomplete combustion state, the temperature detected by the thermocouple 19 is also below the normal range because the flame temperature is low.

  The combustion state monitoring means 16 a provided in the controller 16 stores a threshold value in a normal range of the detected temperature of the thermocouple 19. This threshold value is also determined in stages according to the heating operation level. Thereby, it can be determined whether the gas burner 36 is in an incomplete combustion state or in a normal state.

  As described above, according to the present embodiment, the heating operation can be continued in a normal state without lowering the level of the heating operation.
