Problems solved by technology

[0007] In particular, in order to reduce the leakage of water vapor from the cleaning device, or to reduce the humidity inside the cleaning device, when the exhaust air volume is increased, not only the escaped heat energy will increase, but also a large amount of external air will flow into the cleaning device. Flowing in, cooling the water-type cleaning fluid, the loss of heat energy is greater
[0008] Furthermore, because the ventilation resistance of the exhaust channel connected to the exhaust device of the cleaning device varies according to its diameter, length, number of bends, etc., it is difficult to preset the exhaust air volume of the exhaust device to an optimal value.
In addition, it is also possible to adjust the exhaust air volume with a baffle (damper) installed on the exhaust passage, but it is not easy to obtain the optimum value of the exhaust air volume at the work site. The best way to set the opening of the baffle
[0009] The second problem with the water cleaning device is that even if the exhaust air volume can be adjusted to an appropriate amount, the loss of heat energy due to the exhaust cannot be prevented.

Abstract

The invention provides a cleaning device using a water-based cleaning A cleaning device (1) using a water-based cleaning liquid is filled up with steam produced when the liquid is heated to high temperature. Conventionally, heating or drying the cleaning liquid has caused steam leakage, resulting in a large loss of heat energy. To solve this problem, the cleaning device of the invention is provided with pressure difference measuring device (11) for measuring the pressure difference between the pressure in a gas discharge chamber (10) and the outside air pressure. The amount of discharge gas from the gas discharge chamber (10) is controlled in order that the pressure difference is a predetermined appropriate value, preventing a leakage of excessive steam and enabling the cleaning device to be always operated at an optimum exhaust air flow rate. A heat pump mechanism for recovering the heat of the discharge gas into the cleaning liquid in the cleaning device is installed to re-use the energy dissipated along with the exhaust air.

Description

technical field [0001] The invention relates to a cleaning device using water cleaning liquid, in particular to an energy-saving technology for the cleaning device. Background technique [0002] Currently, washing machines using organic solvents are often used for washing machine parts, etc. However, due to environmental restrictions, etc., the conversion to water-based washing machines is being actively made. [0003] The water cleaning device sprays high-temperature water-based cleaning liquid on the object to be cleaned, or immerses the object to be cleaned in high-temperature water-based cleaning liquid to remove oil and foreign matter adhering to the object to be cleaned. [0004] In this cleaning device, the inside of the cleaning device is filled with water vapor during cleaning. This water vapor leaks from the cleaning object inlet and outlet of the cleaning device, deteriorating the operating environment, and deteriorating the drying performance in the water remova...
