Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a hot air heater having a room temperature control function that detects the room temperature using a temperature sensor and starts and stops the blower. By configuring the room so that indoor air flows into the surrounding area, the temperature sensor can detect changes in the room temperature quickly, and the room temperature control operation can be performed quickly.

To install a temperature sensor on a conventional hot air heater, (1)
The warm air heater is installed outside the main body, (2) inside the ventilation duct, and at the outermost part of the main body, but each is easily damaged by external force and comes into contact with indoor air when the air blowing is stopped. There were some problems, such as it not working.

Furthermore, in a hot air heater that has an indoor air inlet at the top and a hot air outlet at the bottom, the direction of ventilation is completely opposite when the blower is in operation and when it is stopped. (This is because the air flows downward when the air is blown, but when the air is stopped, it flows upward due to the draft from the heat exchanger section.) Therefore, if a temperature sensor is attached to the upper part of the ventilation passage, when the air is stopped, the air flows upward from the heat exchanger section. The temperature sensor is not working even though the room temperature is dropping due to the hot air draft from the
No matter how long it takes without turning it on, the operation will not start, and if a temperature sensor is installed at the bottom of the ventilation passage, it will detect the temperature of the hot air that is heat exchanged during operation, causing malfunctions such as immediately stopping the operation. Sometimes problems occurred.

In order to solve this problem, the present invention achieves the initial objective by providing a structure in which indoor air always flows in the same direction.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is an external view of a fan-equipped convector to which an embodiment of the present invention is applied. The front panel 1 has an indoor air intake port 2 at its upper part and a hot air outlet 3 at its lower part. The front panel 1 is detachably attached to the front of the outer box 4, and legs 5 are attached to the lower part of the outer box 4. Furthermore, a control device 6 is provided at the upper right side of the front panel 1. It is being

FIG. 2 shows the internal structure, and the heat exchanger 7 through which hot water flows and the fan 8 that blows air to the heat exchanger 7 are located in the space A on the left side of the outer box 4, and the space A is A control device 6 is installed in a space B partitioned by a partition plate 9 (used as an example of a partition body).
and a temperature sensor 10 and an electric motor 11 connected thereto.
is provided.

FIG. 3 is a sectional view taken along line 2-' in FIG. 2, and an opening 9a is formed above the partition plate 9.

In this way, the inside of the outer box 4 is divided into two spaces A and B by the partition plate 9, and the upper parts thereof are connected by the opening 9a.

The suction port 2 of the front panel 1 is connected to the partition plate 9
The air outlet 3 is provided only in front of the space A on the left side, and the air outlet 3 is provided over the entire width of the spaces A and B.
The left side of the partition plate 9 acts as an air outlet from the space A, while the right side of the partition plate 9 acts as an inlet into the space B.

The effect will be explained below.

When the fan 8 is driven by the electric motor 11, air is blown. Indoor air is sucked into the space A from the suction port 2 of the front panel 1, and is passed through the filter 1.
2. The hot air passes through the heat exchanger 7 and is blown into the room from the space A through the air outlet 3. At the same time, indoor air flows into the space B from the right side of the outlet 3, passes through the opening 9a of the partition plate 9, passes through the heat exchanger 7, and is blown out from the outlet 3. The indoor air that has flowed into the space B hits the temperature sensor 10 attached to the rear of the air outlet 3, so that the temperature sensor 10 detects the room.

When the electric motor 11 stops, an upward airflow is generated due to the draft caused by the heat of the heat exchanger 7. Due to this airflow, indoor air is sucked in from the lower air outlet 3 and flows out to the upper air inlet 2.
The air current rising at this time has the function of sucking air also from the opening 9a of the partition plate 9. As a result, an upward airflow is generated within the space B on the right side of the partition plate 9,
Indoor air is sucked in through the outlet 3 and hits the temperature sensor 10.

In this way, an air current that always flows from right to left is generated in the opening 9a, and an upward air current is generated to the right side of the partition plate 9. As a result, room air always hits the temperature sensor 10, and changes in the room temperature are immediately detected by the temperature sensor 10, and the control device 6 performs room temperature control.

As described above, according to the present invention, since the temperature sensor is always in the flow of indoor air, very accurate room temperature control can be performed. In addition, the hot air outlet is located at the bottom, which blows warm air to your feet for comfortable heating.

Claims (1)

[Claims] 1 In a hot air heater that sucks indoor air through the upper intake port, blows out warm air from the lower outlet, and controls the room temperature by detecting the room temperature with a temperature sensor, the inside of the outer box is equipped with a partition. The left and right partitions form a space that accommodates a heat exchanger/blower and a space that accommodates a temperature sensor, and the space that accommodates the temperature sensor is communicated with the air outlet, and above the partition is a space that accommodates a temperature sensor. A warm air heater characterized by having an opening so that indoor air flows into a space housing a temperature sensor both when the blower is in operation and when it is stopped.
