Description

[Detailed description of the invention] (Field of industrial application) The present invention mainly relates to a ceiling-suspended hot air heater.

(Prior art) Conventionally, this type of heating machine includes a hot air duct connected to a hot air outlet on the front, a hot air fan on the upstream side of the hot air duct, and a gas burner or other heat source on the upstream side of the hot air duct. Types of hot air blowers are known, but such hot air blowers have the disadvantage that the hot air obtained from the warm air outlet rises in front of the hot air outlet and ends up heating the ceiling surface unnecessarily. In order to eliminate such inconveniences, for example, a floor-standing type has been proposed in which warm air is blown from the bottom and low-temperature circulating air is blown from the top.

(Problem to be solved by the invention) However, in such a device, two fans are provided: a warm air fan for blowing out the hot air, and a circulating air fan for blowing out the circulating air. This is generally a relatively large and expensive device, which has the disadvantage of being relatively large and expensive.

(Means for Solving the Problems) The purpose of the present invention is to obtain a heating machine that does not have such inconveniences, that is, a heating machine that uses one fan in common. , comprising a hot air duct connected to a hot air outlet on the front, a hot air fan on the upstream side of the hot air duct, and a heat source on the upstream side of the hot air duct, wherein the main body includes a cold air chamber on at least one left and right side; An upper cold air blowing chamber having a front cold air blowing outlet that opens above the hot air blowing outlet, and a cold air duct that communicates the cold air chamber with the blowing chamber and extending from the hot air fan into the cold air chamber are provided. An extension part is provided, and the extension part serves as a cold air fan facing upstream of the cold air duct.

(Example) An example of implementing the present invention will be explained with reference to attached drawings.

In the drawing, reference numeral 1 denotes the main body of the heater, which is installed in a suspended manner on the ceiling surface 3, and inside this is a hot air duct 5 connected to the hot air outlet 4 on the front, a hot air fan 6 on the upstream side of the hot air duct 5, and a hot air fan 6 on the upstream side of the hot air duct 5. With a gas burner as a side heat source 7, and thus according to the operation of said fan 6:
Warm air was blown out forward and downward through the air outlet 4. In the drawing, 8 indicates the indoor air inlet on the back side.

Although the above is not particularly different from the conventional one, according to the present invention, a cold air chamber 10 is partitioned into at least one left and right side of the main body 1 via a partition wall 9, and an upper part of the main body 1 is partitioned into a cold air chamber 10. A blowing chamber 13 having a cold air blowing outlet 12 is formed on the front surface through the partition wall 11, and the cold air chamber 1
A cold air duct 14 that communicates the inside of the air with the inside of the blowing chamber 13.
Further, an extension part extending laterally from the hot air fan 6 is provided, and the extension part is made to project into the cold air chamber 10 to form a cold air fan 15 facing the upstream side of the cold air duct 14, and the boundary part thereof A partition plate 17 was provided.

In the illustrated embodiment, a pair of left and right cold air chambers 10 are provided in the main body 1, and a corresponding pair of cold air ducts 14 are provided. In the drawing, reference numeral 16 indicates a motor at the end that drives the fans 6, 15. In the illustrated model, the motor 16 is installed in the cold air chamber 10 on the right side of the drawing, and is located on the back side thereof (not shown) to drive various types of motors. It houses the functional parts for the control of the engine and protects them from damage due to temperature rise.

(Function) To explain its function, along with the ignition of the heat source 7,
According to the operation of the fans 6 and 15, hot air is blown out from the hot air outlet 4, and cold air is also blown out from the cold air outlet 12 above the hot air outlet 4, which acts as circulating air, thus blowing out the inside of the room 2. can eliminate unnecessary temperature rise concentrated on the ceiling surface 3 side, and furthermore,
At this time, both the fans 6 and 15 are formed as one common unit, so that the whole can be miniaturized, and furthermore, the cold air chamber 10 and the blowing chamber 13 are designed to maintain the side and top surfaces of the main body 1 at a relatively low temperature. act.

(Effects of the invention) As described above, according to the present invention, the fan for hot air and the fan for cold air are common, and the whole can be made relatively small and inexpensive. The cooling air chamber and the cold air blowing chamber inside the air conditioner keep the side surfaces and the top surface at a relatively low temperature, thereby facilitating handling.
