Description

[Detailed description of the invention] This invention relates to a heating device with a humidifying function. In other words, heating devices with a humidifying function are conventionally known, for example, those disclosed in Japanese Utility Model Publication No. 58-29394 As shown in the above, there are those that provide a separate heat source for humidification, and those that use the hot air of the heating device itself as the heat source for humidification, as disclosed in Japanese Utility Model Publication No. 58-46330.

However, in the former case, since the heat source is separate from the heating device, the amount of heating for humidification can be adjusted very easily by itself, but on the other hand, it requires a separate heat source such as a heater, which is extremely expensive. In the latter case, since the heating device's own heat source is used, there is no need for a separate heat source for humidification and the cost is low, but on the other hand, the heating amount for humidification cannot be adjusted unless the heating power of the heating device is adjusted. However, it is not easy to adjust the humidification of the humidifier alone, and if you try to force it, the structure becomes extremely complicated.Either way, it has its advantages and disadvantages.

This idea focuses on this point and eliminates the above drawbacks,
It is an object of the present invention to provide a heating device having a humidifying device that does not require a separate heat source, is inexpensive, and allows the amount of humidification to be adjusted very easily and reliably with a simple configuration.

Next, a preferred embodiment of the heating device according to the invention shown in the drawings will be described.

Further, the introduction pipe 14 slopes downward and the return pipe 15 slopes upward to promote convection of hot air.

20 is a pressure regulating chamber formed by covering the tip opening 21 of the return pipe 15 with the partition plate 11 and the guide plate 12 in the combustion chamber 8, and a discharge port 22 that opens above the hot air outlet 2 is provided in the front part. At the same time, one side wall has an opening 23 communicating with the air passage 10, and furthermore, the opening 23 can be opened and closed by operating a lever part 24 protruding from the upper surface of the heater main body 1 outside the opening 23. A damper 25 is provided.

Reference numeral 26 denotes a connecting pipe made of rubber or the like that connects the water tank 17, the steam chamber 18, and the steam chamber 18 and the discharge section 19.

Reference numeral 27 denotes a stand on which the heater main body 1 is placed.

Next, the operation of this embodiment will be explained.

By performing a combustion operation that is well known today, the combustion burner 6 starts combustion, the hot air fan 9 is driven, and the generated hot air is turned into hot air and is blown out from the hot air outlet 2 to heat the room. When the lever part 24 is operated and the damper 25 closes the opening 23 of the pressure regulation chamber 20, the pressure P ₁ in the pressure regulation chamber 20, the pressure P ₂ in the air passage 10 above the guide plate 12, and the introduction pipe When the pressure inside the combustion tube 7 with the opening 14 is P ₃ , the communication between the pressure regulating chamber 20 and the air passage 10 is cut off, so compared to the inside of the combustion tube 7 where the air pressure is applied, Since _P1 becomes _P2 , a part of the hot air generated by combustion in the combustion burner 6 rises in the introduction pipe 14 and flows into the heating chamber 16, and water is stored in the heating chamber 16. The steam chamber 18 containing water is heated to boil water.

Therefore, as a result of this boiling, steam is released from the steam chamber 18 into the room via the release section 19, and the room that has been dried by heating is effectively humidified.

In addition, the hot air that heated the steam chamber 18 and became low temperature by exchanging heat with the water inside flows into the pressure regulating chamber 20 via the return pipe 15, and is pushed through the discharge port 22 while being pushed by the newly flowing hot air. The hot air is discharged from the hot air outlet 2 and blown into the room along with high-temperature warm air, and this flow is repeated one after another.

Furthermore, within the heating chamber 16, regions are formed where the lower part is high temperature and the upper part is low temperature, so that the hot air circulates more smoothly in the heating chamber 16 due to the convection effect, and the humidification speed and Furthermore, the humidification ability is also increased.

Next, when you want to stop humidification, use the lever part 24
When the damper 25 opens the opening 23 by operating the damper 25, the pressure regulation chamber 20 and the air passage 10 communicate through the opening 23, so the pressure in the pressure regulation chamber 20 and the combustion cylinder 7 becomes P ₁ = _P2 , the flow of hot air to the humidifying device 13 is stopped, and the humidifying effect is completely disabled.

Further, the amount of humidification can be freely adjusted by changing the opening state of the damper 25.

Therefore, by using the damper 25 and providing the pressure regulating chamber 20, the humidifying device 13 can be adjusted by the pressure difference between each part.
Since the amount of humidification is changed by adjusting the flow of hot air to the humidifier, there is no need for a strong airtight condition to stop the humidification, compared to a method that only uses a damper to adjust the amount of humidification.The structure is simple, inexpensive, and reliable. It acts on

In short, this device communicates with the combustion chamber 8 in a device that heats the room by releasing hot air generated by combustion of the combustion burner 6 in the combustion chamber 8 into the room together with the hot air fan 9. An airtight heating chamber 1 having an introduction pipe 14 for introducing a part of the hot air and a return pipe 15 for returning this hot air to the combustion chamber 8 again.
6, and the heating chamber 16 is further provided with a steam chamber 18 that communicates with a water tank 17 and stores water therein, and furthermore, the tip opening 21 of the return pipe 15 is connected to the air blowing path 10.
It is covered with a pressure regulating chamber 20 having an opening 23 communicating with the air, and a damper 25 is provided in the opening 23, and the amount of humidification is adjusted by opening and closing the opening 23 with the damper 25. Not only does it require a separate heat source and is inexpensive, but it also includes a pressure regulating chamber and a damper that changes the pressure state within the pressure regulating chamber, allowing you to freely adjust the amount of humidification in the humidifier regardless of the heating power of the heating device. It is extremely convenient, and since it uses the pressure difference to change the flow of hot air and adjust the amount of humidification, it does not require airtight precision, is simple to construct, is inexpensive, and works reliably. It has the following.
