Description

[Technical field]

[0001] The present invention relates to a cleaning device for an indoor unit of an air-cooled air conditioner. [Background technology]

[0002] In recent years, the development of storage batteries has progressed, and small, lightweight, large-capacity lithium iron phosphate storage batteries are being sold at relatively low prices. Similarly, the power generation efficiency of solar panels has improved, and they are being sold at low prices. Cleaning of air-cooled air conditioner parts, such as heat exchanger aluminum fins (hereafter referred to as aluminum fins) and blower fans is done by removing the parts from the air-cooled air conditioner housing, but wiping them down with a rag or cleaning them with a spray can is not sufficient. For oil stains in particular, it is preferable to use hot water at 40 degrees Celsius or higher. The inventors have applied for a patent (Patent Document 1) for a device that connects a high-pressure washer to an instantaneous water heater that uses a propane gas cylinder as a heat source. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2006-003060 A DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0004] The inventors have constructed a device that supplies hot water by connecting a propane cylinder to a gas-powered instantaneous water heater, and have washed off oil stains and the like with a high-pressure washer, but this has the following problems. Problem 1. Considering portability and safety, we are currently using 10kg propane gas cylinders. However, they are heavy, have a large volume, and are inconvenient to handle. Issue 2: There is a legal requirement that propane gas cylinders and instantaneous water heaters be installed at least 2m apart, so the location of propane gas cylinders is considered for each site. Issue 3: The cleaning work is carried out with the risk of the gas cylinder running out of gas and not being able to use hot water. Issue 4: When gas runs out, it is necessary to take the empty container to a gas company's propane gas filling station and take the trouble to refill it. Issue 5: How to deal with the risk of fire. Carrying a fire extinguisher is essential. In factories, it is necessary to notify the factory in advance of bringing in firearms. Problem 6. A propane gas instantaneous water heater requires an AC 100 volt power supply, but in this invention, it can be supplied from an inverter power outlet. Conventionally, the power outlet in the customer's building has been borrowed. Problem 7. When propane gas is burned incompletely, carbon monoxide gas, which is dangerous to the human body, is produced. [Means for solving the problem]

[0005] The present invention has been made in view of the above problems, and from a first perspective, a device has been devised in which a propane gas instantaneous water heater is replaced with an electric instantaneous water heater. The electric instantaneous water heater is powered by AC 100 volts using natural energy generated by solar panels. The 100 volt AC power supply for the electric instantaneous water heater is provided by supplying natural energy generated by solar panels to a storage battery, which is then connected to a DC / AC inverter device to provide a 100 volt AC power outlet. By connecting the power cord of an electric instantaneous water heater to the AC 100 volt power outlet and supplying water from the faucet to the electric instantaneous water heater, the device can supply hot water to the washing machine. In the second aspect, electricity generated by natural energy from solar panels is supplied to a storage battery. The storage battery, DC / AC inverter device, and electric instantaneous water heater are integrated into a portable device. The hot water supply device is characterized by being able to be moved from the work vehicle when charging is complete.

[0006] The cleaning device of the present invention will be described with reference to FIG. In Figure 1, solar panels 2 are installed on the roof of a work vehicle (wagon van) 1, and the electricity generated is charged in a storage battery 4 via a charge controller 3. The output of the storage battery 4 is supplied to a DC / AC inverter device 5. When the power cord of an electric instantaneous water heater 6 is inserted into the output power outlet 7 of the DC / AC inverter device 5 and water is supplied from the faucet, the device can supply hot water.

[0007] That is, in the second aspect of the present invention, a hot water supply device is configured in a portable form in which a storage battery, a DC-AC inverter device, and an electric instantaneous water heater are integrated. When charging of the storage battery 4, which is charged with natural energy from the solar panel 2 installed on the roof of the work vehicle, is completed, it is preferable to remove the power cord from the solar panel 2 and move the integrated hot water supply device 21 outside the vehicle to supply hot water to the high-pressure washer 9. Effect of the Invention

[0008] The present invention is characterized in that an electric instantaneous water heater 6 is used as the heat source for hot water supply, and the AC 100 volt power supply to the electric instantaneous water heater 6 is configured in the form of a solar panel, a storage battery, and a DC-AC inverter device. A device with the following features is configured to compensate for the shortcomings of the propane gas instantaneous water heater described above. Feature 1. There is no need to worry about dealing with the risk of propane gas fires or preparing fire extinguishers. Feature 2: The solar panels installed on the roof of the vehicle are constantly charging, eliminating the risk of running out of propane gas or having to worry about timing the refills. Feature 3: If there is a propane gas shortage, there is no need to go to the trouble of bringing propane gas to a gas company's filling station to refill. Feature 4: An AC 100 volt power supply is essential for electric instantaneous water heaters. There is no need to prepare again. Feature 5. The hot water supply device is integrated and has a movable form, so it can be moved close to the object to be cleaned, improving work efficiency. Feature 6: When bringing a propane cylinder into a factory, a prior notification of firearms is required, but since the device of this invention is not considered a firearm, there is no need to submit a notification. Feature 7. Electric instantaneous water heaters are equipped with electric heaters that run on AC 100 volts power to produce hot water. Therefore, they do not produce carbon monoxide gas, which is dangerous to the human body. [Brief description of the drawings]
