JPH1111145A - Spot cooler installed on ceiling of forklift car - Google Patents

Abstract

PROBLEM TO BE SOLVED: To easily mount a spot cooler on a forklift car without requiring piping work for connecting a compressor with a heat exchanger, by using the compressor with a motor, using an engine-driven generator or a battery as power supply, and building in an inverter. SOLUTION: A spot cooler 1 is provided for an appropriate place of a forklift car, for example, for the upper part of a frame for protecting a cabin. The spot cooler 1 is equipped with a compressor with a motor which is driven with power supply from an engine-driven generator or a battery which is placed in the forklift car. Because the power supplied from the generator or the battery is direct current, a DC-AC inverter for converting the power to alternating current is built in. By integrating the compressor with a heat exchanger, piping work for connecting a compressor with a heat exchanger is not required, and the spot cooler 1 is easily installed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spot cooler installed on a ceiling of a forklift truck.

[0002]

2. Description of the Related Art As a conventional spot cooler installed on the ceiling of a forklift vehicle, there is a spot cooler that operates a compressor using the power of an engine.

[0003]

The conventional spot cooler installed on the ceiling of a forklift vehicle has the following problems. That is, since the power of the engine is transmitted to the compressor using the belt and the compressor is operated, the compressor must be provided near the engine. Therefore, the heat exchanger must be provided at a separate location, such as at the ceiling, and the compressor near the engine. Therefore, a pipe for conveying the refrigerant between the compressor and the heat exchanger is required.

However, this piping work is troublesome, and mounting a spot cooler on a forklift truck is often avoided.

Accordingly, an object of the present invention is to provide a spot-mounted spot cooler for a forklift vehicle that does not require piping work.

[0006]

In order to solve the above-mentioned problems, the present invention uses a compressor having a built-in electric motor, and uses an engine-driven generator or a battery as a power source. By using a compressor with a built-in electric motor,
Unlike a spot cooler using the power of a conventional engine, it is not necessary to provide a compressor near the engine, so that the compressor and the heat exchanger can be integrated. This eliminates the need for piping work.
On the other hand, wiring for receiving supply of electricity from a generator or a battery is required. However, since it is a simple operation of laying an electric wire, a burden on a spot cooler is small.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing an embodiment of the present invention. Although not shown, the compressor in the spot cooler (1) is operated by receiving power supplied from an engine-driven generator or a battery attached to the main body of the forklift vehicle.

[0008] The spot cooler (1) itself has the same seismic function as that of a normal spot air conditioner or window air conditioner. However, since the electric power supplied from the generator or the battery is a direct current, a DC-AC inverter for converting into an alternating current is built in.

[0009]

According to the present invention, since the electric power is used as the driving source of the compressor as described above, the compressor and the heat exchanger can be integrated with each other. This eliminates the need for piping work between the compressor and the heat exchanger. Therefore, it is possible to provide a spot cooler for a forklift vehicle that can be easily attached.
