Description

BACKGROUND OF THE INVENTION
The present invention relates to a steam recovery apparatus for a cleaning and disinfecting machine having a novel configuration capable of preventing adverse effects on other equipment.
[Prior art]
As shown in FIG. 11, the steam recovery apparatus used in a conventional filth washing and disinfecting machine includes an overflow / exhaust pipe 50 and discharges steam to a part of the overflow / exhaust pipe 50 through which overflow water flows. 51 is provided so that the steam from the waste washing and disinfecting machine is discharged from the steam discharge port 51 toward the outside air.
[Problems to be solved by the invention]
However, in the case of such a conventional configuration of the overflow / exhaust pipe 50, the exhaust process of the primary steam disinfection discharges the steam as it is to the outside air, so that when the steam pressure in the cleaning tank rises, the steam discharge port 51 The steam directly went out and steam leakage outside the machine could not be prevented.
For this reason, the problem that the dew condensation on the wall surface of the overflow / exhaust pipe 50 and an obstacle to other devices (damage of the wall surface of the electrical device, etc.) occurred.
The present invention has been made in view of the above circumstances, and is capable of eliminating the outflow of steam from the overflow / exhaust pipe to the outside, preventing condensation on the wall surface and the like, and preventing adverse effects on other devices. An object of the present invention is to provide a steam recovery apparatus for a machine.
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a steam recovery apparatus for a cleaning and disinfecting machine according to claim 1 is connected to a waste cleaning / disinfecting machine by an overflow / exhaust pipe, and is connected to the waste cleaning / disinfecting machine via an overflow / exhaust pipe. In a steam recovery apparatus for cleaning and disinfection equipment that performs steam recovery and overflow water circulation, a tank that stores cooling water, and the lower opening is disposed in the tank, and the filth cleaning is performed through the overflow and exhaust pipe. It is connected to a disinfectant, and has a box-shaped steam recovery device in which an overflow and exhaust pipe provided on the upper side is opened in the tank, and an air vent hole provided in the upper wall of the tank. is there.
According to a second aspect of the present invention, in the steam recovery apparatus for the cleaning and disinfecting apparatus according to the first aspect, the steam recovery unit has cooling fins arranged on either the upper surface or the peripheral surface. It is a feature.
According to the present invention, when the vapor pressure in the filth washing / disinfecting machine rises, the pressure vapor passes through the vapor recovery device in the tank containing the cooling water, the pressure vapor is cooled and becomes water droplets, and is stored in the tank, or It flows down from the overflow / exhaust tube to the waste cleaning / disinfecting machine through the steam recovery unit and the overflow / exhaust pipe. On the other hand, the pressurized air flows out from the air vent hole.
Thereby, the outflow of the vapor | steam outside an apparatus can be eliminated, the dew condensation to a wall surface etc. and the bad influence to other apparatuses can be prevented (damage of the wall surface of an electric equipment etc.) can be prevented.
In addition, the steam recovery unit can be configured to arrange cooling fins on any one of its peripheral surfaces, and in particular, with a configuration in which cooling fins are arranged on the upper surface of the steam recovery unit, By more effectively cooling the pressure steam and increasing the steam cooling effect and shortening the cooling time, it is possible to effectively prevent the steam from flowing out of the apparatus.
