Abstract

PROBLEM TO BE SOLVED: To realize an increase in maximum heating capacity immediately after start of an operation, an improvement in burn-off removal performance of air contaminating substance and heating without conducting combustion during sleeping. SOLUTION: The regenerative heater comprises a blower 4, a combustion cylinder 3 having a burner 2, a regenerative unit 10a, an electric heater 12, and a heat shielding air duct plate 13 for partitioning an air duct from the blower 4 into a regenerative unit air duct 14 and a combustion cylinder air duct 15 to eliminate influence of combustion warm air to the unit 10a. Since warm air of the unit 10a and warm air of the heater 12 are applied to the warm air, maximum heating capacity can be more increased at the necessary time of raising a room temperature immediately after start of an operation. Since the indoor air is also introduced into the duct 14 to bring the high temperature unit 10a into contact with the heater 12, burn-off removal performance of air contaminating substance is improved. Further, since no combustion is conducted when the heater 12 is solely operated to heat, continuous heating during sleeping can be achieved.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat storage and heating apparatus capable of producing hot air by means of a heat storage section which has been heated and stored and a combustion and electric heater, and further capable of burning off air pollutants.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 17, a heating device of this type includes a burner 2 in a main body casing 1, a combustion tube 3 equipped with the burner 2, and a blower for sucking and blowing indoor air. 4, a guide 5 for regulating the flow direction of the air flow by the blower 4, a mixing unit 6 for mixing the combustion exhaust gas from the burner 2 with the room air from the blower 4 to make the hot air, Hot air outlet 7
It was composed of a room temperature sensor 8 for detecting a room temperature, and a control unit 9 for controlling the burner 2 and the blower 4.

In the case of heating in the above configuration, the burner 2 is burned by the control unit 9 and the blower 4 is driven, so that the combustion exhaust gas from the burner 2 and the room air from the blower 4 are mixed in the mixing unit 6. As a result, hot air was blown out from the hot air outlet 7 to heat the room. Then, the room temperature is detected by the room temperature sensor 8, and when the room temperature reaches the set temperature, the combustion of the burner 2 is stopped to control the temperature to a constant temperature.

[0004] Other conventional combustion heating devices include:
As shown in FIG.
A combustion tube 3 disposed so as to surround a combustion portion of the burner 2, a blower 4 for sucking and blowing room air,
Guide 5 for regulating the flow direction of the air flow by blower 4
A mixing section 6 of combustion exhaust gas and air formed by the guide 5, and a heat storage section 1 disposed around the mixing section 6.
0, a hot air outlet 7 for blowing out hot air, and a control unit 9 for controlling combustion and operation of the blower.

[0005] The above-mentioned regenerative combustion heating device comprises a blower 4
When the burner 2 is burned by supplying combustion air, the combustion exhaust gas is discharged from the outlet of the combustion tube 3 and reaches the mixing section 6. On the other hand, the flow direction of the air flow supplied from the blower 4 is regulated by the guide 5 and reaches the mixing section 6 where it is mixed with the combustion exhaust gas. The heat storage member 10 is heated by the mixed flow, and the mixed flow is then blown out as hot air from the hot air outlet 7. When the combustion is stopped, the air flow supplied from the blower 4 receives heat from the heat storage unit 10 and continues to emit hot air for a certain period of time even after the combustion is stopped.

[0006]

However, in the conventional combustion heating apparatus as described above, when the maximum combustion amount of the burner 2 is inappropriate for the size of the room to be heated, for example, the room is too large. And the room temperature rise speed naturally slows down,
There has been a demand for a combustion heater having an ideal heating capacity in which the maximum heating capacity increases when the room temperature rises immediately after the start of operation.

Further, air pollutants such as mold and tobacco smoke are floating in the indoor air, and it is said that these can be burned off at 300 ° C. or higher. Is small, and most of the air is directly supplied to the mixing section 6, so that the burn-off removal performance of air pollutants is not good.

Further, when burning, ventilation of room air is necessary, but ventilation cannot be performed by opening windows during sleep, so that heating by combustion operation during sleep has not been usually performed. Therefore, during sleep, another electric heating device or a combustion heating device in which combustion exhaust gas is not released indoors is used.

On the other hand, in the thermal storage combustion heating apparatus having the thermal storage unit, the thermal storage unit 10 shows the maximum value of the instantaneous heat storage immediately after the start of the operation, and since the heat is stored, the heating output decreases by the heat amount. There was a problem that the maximum heating output could not be exhibited immediately after the start of the operation requiring the heating output.

At the time of bedtime, the combustion is stopped and the heat storage section 1 is stopped.
Although it can be heated to warm air by 0, the amount of heat storage gradually decreases and disappears after a certain period of time, so that the heating output does not become constant and the room temperature cannot be kept constant, so that there is a problem that it is not possible to sleep comfortably.

[0011]

It consists of an outlet.

According to the invention, the electric heater is energized in advance to heat and store heat in accordance with the operation start time, and when the operation start time comes, the blower is driven and the heat is stored in the heat storage unit and the electric heater. Since heat is exchanged with the wind and the hot combustion air from the combustion tube is also added, the maximum heating capacity is further increased when the room temperature rises immediately after the start of operation. In addition, the rate at which room air is directly supplied to the mixing section is reduced, and the performance of burning off air pollutants is also improved.

The introduced indoor air is divided into a heat storage section air path and a combustion cylinder air path 15 by a heat shield air path plate,
The indoor air introduced into the heat storage unit air passage is heat-exchanged into warm air by the heat storage unit and the electric heater. In addition, the air comes into contact with the indoor air combustion tube introduced into the combustion tube air passage, and heat is exchanged into warm air. Furthermore, it is mixed with the appropriate temperature hot air in the mixing section and blown out from the hot air outlet, so that the hot air in the heat storage section and the hot air in the electric heater are added to the combustion hot air, so when the room temperature rises immediately after the start of operation, The maximum heating capacity can be further increased. In addition, since the indoor air is also introduced into the heat storage unit air passage, it comes into contact with the high-temperature heat storage unit and the electric heater, so that the ratio of air directly supplied to the mixing unit at room temperature decreases, and burn-out removal of air pollutants Performance is improved. Further, when the electric heater is used alone for heating operation, combustion is not used, so that there is an advantageous effect that continuous heating during sleep can be performed.

Further, a heat shield air path plate is provided above the combustion cylinder,
Further, a heat storage section and an electric heater are provided on the upper part, and the lower part of the heat shield air path plate is a combustion cylinder air path to the combustion cylinder, and the upper part is a heat storage part air path to the heat storage part. When the portion is heated and stored, the heated air rises in relation to the specific gravity and heats and stores the heat storage portion efficiently. Moreover, since the upper part of the heat storage part is covered with the heat storage part heat insulating material, it is possible to prevent the air heated in the heat storage part having a high temperature from rising. Furthermore, since the heat shield air path plate is located above the combustion tube, the heat exchange of the electric heater and the heat storage section to the warm air can be efficiently performed without being affected by the heat of the combustion warm air of the combustion tube.

The heat storage section has a fin-shaped surface on the lower surface facing the air path of the heat storage section so as to be parallel to the flow of air from the blower. The heat storage performance by the heater and the heat radiation performance to the warm air increase.

Also, the heat storage unit air passage is divided along both the upper surface of the heat storage unit and the lower surface of the heat storage unit on the side closer to the blower of the heat storage unit, and merges at the outlet side of the heat storage unit. Since the heat storage unit exchanges heat on both the upper surface and the lower surface, the heat transfer area increases, and the heat radiation performance to warm air increases.

The heat storage unit has a fin-shaped surface on both the upper surface and the lower surface facing the air path of the heat storage unit so as to be parallel to the flow of air from the blower, so that heat exchange is performed on both the upper surface and the lower surface. Further, since the heat transfer area is further increased by the fin-shaped surface, the heat storage performance by the electric heater and the heat radiation performance to the warm air are further improved.

Further, since the electric heater is provided between the upper surface of the heat storage section and the air path of the heat storage section, the radiant heat generated by the electric heater reaches the blower and its vicinity from the air path of the heat storage section. Abnormal heating can be prevented.

Further, when viewed from the front of the apparatus, a heat shield air path plate is provided vertically outside the side surface of the combustion cylinder, and an electric heater and a heat storage section are provided further outside the heat shield air path plate, so that the wind from the blower is provided. By setting the operation start time, the control unit energizes the electric heater in advance to heat and store the heat storage unit, and the operation start time is reached. While driving the blower, the burner also burns, and the introduced indoor air is divided into a heat storage section air path and a combustion cylinder air path by a heat shield air path plate, and the indoor air introduced into the heat storage section air path is used as a heat storage section. Heat is exchanged for warm air by an electric heater. Also,
The room air introduced into the combustion tube air passage contacts the combustion tube and exchanges heat with warm air. Further, in the mixing section, the warm air from the heat storage section air passage and the combustion tube air passage and the combustion warm air from the combustion tube are mixed into a warm air of an appropriate temperature and blown out from the warm air outlet. Therefore, since the hot air in the heat storage unit and the hot air in the electric heater are added to the combustion hot air, the maximum heating capacity can be further increased when the room temperature rises immediately after the start of operation. In addition, since the indoor air is also introduced into the heat storage unit air passage, it comes into contact with the high-temperature heat storage unit and the electric heater, so that the ratio of air directly supplied to the mixing unit at room temperature decreases, and burn-out removal of air pollutants Performance is improved. Furthermore, if the electric heater is used alone for heating operation, combustion is not used, so that continuous heating during sleep can be performed.

Further, by providing the heater heat reflecting plate for reflecting the radiant heat generated by the electric heater to the heat storage unit facing the electric heater, the radiant heat generated by the electric heater in the direction not directly reaching the heat storage unit is reflected by the heater heat reflection plate. Since the plate reflects the heat to the heat storage unit, the radiant heat of the electric heater, which has heated other parts without directly heating the heat storage part, can be efficiently used for heat storage, and the temperature rise of other parts can be prevented.

Further, among the radiant heat generated by the electric heater, the radiant heat in the angular direction that does not directly reach the heat storage portion, when viewed from the cross section, has a concave cross-sectional shape determined so that the reflection angle reaches the heat storage portion. By making the shape a smooth curve, the radiant heat generated by the electric heater in the direction that does not directly reach the heat storage unit is reflected by the heater heat reflection plate to the heat storage unit, so it is not necessary to directly heat the heat storage unit. The radiant heat of the electric heater that has heated the portion can also be efficiently used for heat storage, and the temperature rise of other portions can be prevented.

Further, among the radiant heat generated by the electric heater, the radiant heat in the angular direction which does not directly reach the heat storage portion when viewed from the cross section of the heater heat reflecting plate is bent so that the reflection angle reaches the heat storage portion to obtain a straight line. Radiated heat in the direction that does not directly reach the heat storage unit due to the radiant heat generated by the electric heater is reflected by the heater heat reflection plate to the heat storage unit, so that the heat storage unit does not directly heat the heat storage unit. The radiant heat of the electric heater that has heated other parts can also be efficiently used for heat storage, and the temperature rise of other parts can be prevented.
Also, it is easy to manufacture.

Further, since the heater heat reflecting plate is integrated with the heat shield air path plate, the radiant heat generated by the electric heater also reflects the radiant heat in the angular direction which does not directly reach the heat storage portion to the heat storage portion. Furthermore, the space occupied in the heat storage unit air passage can be reduced as compared with the case where the air conditioner is separately installed, and the ventilation resistance is reduced. Further, the production cost can be reduced.

Further, the radiant heat generated by the electric heater and the radiant heat from the heat storage unit are reflected so as not to reach the blower to be heated, and the blower-side heater heat so as not to obstruct the flow of the wind from the blower to the heat storage unit air passage. By providing a leakage prevention wind direction plate, the radiant heat generated when the electric heater is energized and the radiant heat generated from the high-temperature heat storage unit does not directly reach the heat storage unit, and the radiant heat to the blower prevents heat leakage from the blower-side heater. In order to prevent the wind direction plate from reflecting and leaking,

Further, the radiant heat generated by the electric heater and the radiant heat from the heat storage section exit the air path of the heat storage section, reach the mixing section and its surroundings, are reflected so as not to be heated, and are reflected from the air path of the heat storage section and the vicinity thereof. By providing a heat leak prevention wind direction plate on the mixing unit side so as not to obstruct the flow of air to the air path, the radiant heat generated when the electric heater is energized and the radiant heat generated from the heat storage unit that has become hot Since the radiant heat exiting the heat storage unit air path and flowing in the direction of the mixing unit and its surroundings is reflected and prevented from leaking by the heat leakage prevention wind direction plate on the mixing unit side, the mixing unit and its surroundings are not heated to an abnormally high temperature. In addition, the flow of air from the heat storage unit air passage to the mixing unit and the air passage around the mixing unit is not hindered.

Further, a heat shield air path plate is provided above the combustion cylinder,
The upper heat storage part is provided on the upper part, the upper heat storage part is further provided on the upper part, and the heat storage part air passage from the blower and the electric heater are provided between the upper heat storage part and the lower heat storage part, so that the electric heater is energized. Most of the radiant heat generated reaches the upper heat storage section and the lower heat storage section and is efficiently stored. When the indoor air is heated by hot air, the air is separated into an upper heat storage portion and a lower heat storage portion, so that the heat radiation area increases, and heat can be efficiently radiated and heated to warm air.

Further, a cylindrical heat storage section is provided at the upper part of the combustion cylinder so that the core direction thereof is the direction of the wind from the blower, and the heat storage section is connected to the heat storage section air passage from the blower. By providing the electric heater in the internal space, the radiant heat generated when the electric heater is energized, most of the radiant heat reaches the heat storage unit because the heat storage unit has a cylindrical shape corresponding to all directions of 360 °.
Heat is stored efficiently. Also, in the case where the heat storage unit is heated to the warm air by the heat radiation from the heat storage unit, the heat radiation area of the heat storage unit is increased, and the heat can be efficiently radiated and heated to the warm air.

The radiant heat generated by the electric heater and the radiant heat generated by the high-temperature heat storage unit are reflected from the inlet and outlet of the air passage of the heat storage unit so as to reach the blower and its surroundings, the mixing unit and its surroundings so as not to be heated. By providing a heat storage unit air path opening / closing plate that opens in the wind traveling direction by receiving the wind from the blower, when heat is stored in the heat storage unit, the radiant heat generated by the electric heater and the radiant heat generated from the high-temperature heat storage unit are reduced. Since the inlet and outlet of the heat storage unit air passage are closed by the heat storage unit air passage opening / closing plate, the heat transfer unit does not reach the fan and its surroundings, the mixing unit and its surroundings, and is not heated to an abnormally high temperature. In the case where the heat storage unit is heated to the warm air by the heat radiation, the inlet and the outlet of the heat storage unit air passage are opened by the heat storage unit air passage opening / closing plate.
