Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a device for assisting heating of a forklift with a cabin used in a refrigerator or the like.

[Prior Art] Conventionally, a forklift used in a low-temperature area such as inside a refrigerator is provided with a cabin 1 as shown in FIG. 4 for the purpose of protection from the cold. is generally installed.

In such forklifts with a cabin, heat wire glass is used in each of the windshield, side glass, rear glass, and front glass to prevent fogging, but the area of the glass is increased to widen visibility. Therefore, the amount of electricity consumed to prevent fogging is extremely large. Therefore, in order to suppress further electricity consumption and prevent a reduction in battery operating time, the output of the heater 2 has been limited to a small value.

[Problems that the invention aims to solve] As described above, with the conventional technology, the amount of electricity supplied to the heater is suppressed, so it is not possible to increase the heating capacity of the heater, and it is not possible to sufficiently heat the inside of the cabin. The problem was that it was not possible to do so.

The purpose of this invention is to provide extremely effective means for quickly eliminating such problems.

[Means for Solving the Problems] Therefore, in this invention, the warm air generated when cooling the control device 4 (see Fig. 4) installed in the front protector 3 is This was done in consideration of the fact that the air is discharged from the hole to the outside, and a small fan is used to
It is characterized in that the air inside the cabin is taken into the front protector, and the air heated by a control device installed inside the front protector is discharged into the cabin.

[Function] In the heating auxiliary device for a forklift with a cabin according to this invention described above, the heating inside the cabin is supplemented by the air that has absorbed the heat from the control device.

[Embodiments] Hereinafter, preferred embodiments of the heating auxiliary device for a forklift with a cabin according to this invention will be described in detail with reference to the drawings.

Note that the same or equivalent parts as in the conventional configuration will be described using the same reference numerals.

In FIGS. 1 and 2, a control device 4 is provided approximately in the center of a sealed front protector 3. As shown in FIG. One opening is provided on one side of the panel 5 of the front protector 3 located inside the cabin 1, and a punching metal 6 is attached so as to close this opening.
Further, an opening is provided on the other side of the panel 5,
A small fan 7 with very low power consumption is attached to this opening so that the air inside the front protector 3 can be exhausted. A guide duct 8 is attached to the front surface of the air blowing portion of the small fan 7, and directs the flow of discharged air in an appropriate direction, for example, downward.

To explain the operation of the heating auxiliary device according to this invention in the above-described configuration, when the small fan 8 is rotated, the air inside the cabin 1 is sucked into the front protector 3 through the holes in the punching metal 6, and the control By passing around the device 4, heat is removed and the control device 4 is cooled. This air, which has been warmed by absorbing the heat from the control device 4,
It is discharged into the cabin 1 through the guide duct 8 by the small fan 7, and by repeating this process,
The air temperature inside the cabin 1 gradually rises.

In addition, this invention, as shown in Figure 3,
The guide duct 9 that guides the exhaust air from the small fan 7 is branched, and one branch path 9a is connected to the cabin 1.
The other branch path 9b is guided outside the cabin 1, and the butterfly damper 1 is installed at the branch point.
0 may be attached so that either one of the branch paths 9a and 9b can be closed.

By configuring as shown in FIG. 3, when heating inside the cabin 1 is not necessary, the butterfly damper 10 is swung by a lever (not shown) to close the branch passage 9a inside the cabin 1.
By discharging warm air to the outside, it is possible to prevent an unnecessary temperature rise inside the cabin 1.

[Effects of the invention] As described above, this invention has a simple configuration using a small fan that does not have a large effect on battery consumption, and it is possible to remove heat from the control device that was conventionally discharged to the outside. It can be effectively used as an auxiliary for heating the inside of the cabin, and the effect of greatly improving the driving environment is tremendous.
