Description

[Detailed description of the invention] [Industrial application field] This invention is a hot air heating device, in particular, a burner that burns liquid fuel, a wind tunnel that guides the heat generated by the burner to a hot air outlet, and a The present invention relates to a hot air heating device having a blowing fan that sends out hot air from the hot air outlet.

[Prior Art] Figures 2 and 3 are a side sectional view and a front sectional view showing a conventional hot air heating device, and in the figures, 1 is a vaporizer for vaporizing liquid fuel such as kerosene;
is a burner that mixes and burns the fuel vaporized by the vaporizer 1, 3 is a combustion tube for guiding the heat generated by combustion upward, 4 is a hot air outlet, 5 is
is a blower fan for converting heat into hot air; 6 is the outer shell of the hot air heating device; 7 is a filter for filtering out dust, etc. in the outside air sucked in by the blower fan 5; 8 is heat generated by combustion. 9 is a cartridge tank for storing kerosene; 10 is a sub-tank that supports the cartridge tank 9 and maintains a constant oil level; 11 partitions the cartridge tank 9 and the wind tunnel 8. The cartridge tank is covered with a partition plate and an outer shell 6.

Next, the operation will be explained. An electric heater (not shown) is incorporated in the vaporizer 1, which instantly vaporizes liquid fuel such as kerosene and sends it to the burner 2. The gasified fuel sucks a suitable amount of air into the burner 2 by the ejector effect, mixes with each other, and burns on the upper surface of the burner 2.

The heat generated by combustion passes through the wind tunnel 8 by rotating the blowing fan 5 and blowing the air, and is turned into warm air from the hot air outlet 4 located at the front of the outer shell 6 of the hot air heating device. Air blows to warm the room, etc.

At this time, when the room temperature is lower than the set temperature, strong combustion occurs, as the room temperature gradually approaches the set temperature, the amount of combustion decreases, and when the room temperature rises above the set temperature, extinguishment or weak combustion occurs.

[Problem that the invention aims to solve] Since the conventional hot air heating system is configured as described above, it is safe as a device even if strong combustion continues, but when the room is cold, The problem was that even with combustion, it did not get very warm.

This idea was made in order to solve the problems mentioned above, and to obtain a hot air heating device that can quickly warm up the temperature of a room by forcing large combustion only when the temperature of the device is particularly low. With the goal.

[Means for Solving the Problems] The hot air heating device according to this invention has a temperature sensor disposed near the cartridge tank and sub-tank, which particularly require temperature control for safety reasons.

Based on the temperature detection value of the temperature sensor, the combustion amount is forcibly controlled to be maximized only when the temperature detection value is below a predetermined temperature in the early stage of combustion, and the combustion amount is controlled to be forcibly maximized only when the temperature detection value is above a predetermined temperature. The present invention is characterized by comprising combustion control means for adjusting and controlling the amount of combustion so that the temperature reaches a predetermined temperature when

[Function] In the hot air heating device of this invention, the temperature of the device is detected by a temperature sensor installed near the cartridge tank and sub-tank, and the combustion amount is forcibly increased only when the temperature is below a certain predetermined temperature.

That is, by detecting the temperature in the vicinity of the tank, the combustion amount can be forcibly increased to a predetermined temperature, and the fuel can be continuously controlled to perform early heating.

[Example] Hereinafter, an example of this invention will be described with reference to the drawings. In FIG. 1, the same parts as in FIGS. 2 and 3 are designated by the same reference numerals. Reference numeral 12 denotes a temperature sensor provided at the lower end of the partition plate 11 near the cartridge tank 9 or sub-tank 10.

Next, the operation will be explained. The gasified fuel sucks a suitable amount of air into the burner 2 by the ejector effect, and the two are mixed with each other and combusted on the upper surface of the burner 2. The heat generated by combustion is blown out as warm air through the wind tunnel 8 by the blower fan 5 and from the hot air outlet 4 located at the front of the outer shell 6 of the warm air heating device, and is blown out indoors etc. warm.

At the beginning of combustion, the temperature of the device is low, the same as the room temperature. At this time, the temperature detected by the temperature sensor 12 is low, and the output of this temperature sensor is sent to a microcomputer (not shown) as a combustion control means, and the commands from the microcomputer A combustion control mechanism (not shown) is controlled to force a large amount of combustion to quickly heat the room. When the temperature inside the device rises due to this forced large combustion and the temperature detected by the temperature sensor 12 reaches a predetermined temperature, the output of the temperature sensor 12 at this time is sent to the microcomputer, and the combustion control mechanism is controlled by commands from the microcomputer. This enables strong combustion operation that allows continuous combustion for long periods of time.

That is, based on the temperature detection value of the temperature sensor 12, the microcomputer determines whether the temperature is at the initial stage of combustion.
The combustion amount is controlled to be forcibly maximized only when the detected temperature value is below the set temperature.

After that, as the temperature of the room rises and approaches the set temperature, the combustion amount is decreased, and when the detected temperature value is higher than the set temperature, the combustion amount is adjusted so that the set temperature remains constant. For example, when the room temperature rises above the set temperature, the fire is extinguished or weak combustion is started.

As mentioned above, by controlling the combustion amount using the output of the temperature sensor, it re-burns immediately after extinguishing the fire and generates a large amount of heat, unlike the time-based control, which allows the temperature of the cartridge tank, sub-tank, etc. to exceed the standard. There is no danger of it becoming too high.

In the above embodiment, the temperature sensor 12 was provided at the lower end of the partition plate 11, but if the temperature sensor 12 is provided at the center of the plurality of temperature sensor partition plates, safety will be further improved, and The temperature of the cartridge tank 9 can also be safely protected.

[Effects of the invention] As described above, according to this invention, a temperature sensor is provided near the cartridge tank and sub-tank, so that the temperature of the cartridge tank and sub-tank can be adjusted during heating without raising the temperature above the standard. A large amount of heat can be safely and reliably heated only in the initial stage.
It has the unique effect of being able to continuously control the amount of combustion and efficiently performing early heating.
