Description

[Detailed description of the invention] The present invention relates to a liquid recovery chute device that collects dirty liquid after cleaning in a cleaning process in which high-pressure liquid is jetted onto the object to be cleaned that is transported to the cleaning chamber of a washing machine. It is.

Conventionally, in the cleaning chamber of a washing machine, the dirty liquid after cleaning the object to be cleaned is collected by a liquid recovery chute device installed below the cleaning chamber, sent to a filtration device, filtered, and then supplied to the cleaning chamber again. It is circulating. However, since the dirty liquid after cleaning is collected by the liquid recovery chute device and sent to the filtration device by gravity, foreign substances such as chips that have adhered to the object to be cleaned may adhere to the bottom of the liquid recovery chute device. After the cleaning process ends or before the cleaning process starts, the operator has to manually clean the chips and other foreign substances that have adhered to the bottom surface, which poses problems such as a lot of time and effort being spent on this cleaning. There is.

An object of the present invention is to provide a liquid recovery chute device which solves the above problems and efficiently removes foreign substances such as chips adhering to the bottom surface.

For this reason, the configuration of the present invention is such that a side wall frame is fixed to the periphery of a bottom member having an inclined surface, a chute portion is provided at an inclined lower end of the bottom member, and a bottom member and a chute are provided at an inclined upper end of the bottom member. , a slit-shaped nozzle is formed by a frame and a slit shielding member whose one end is fixed to the frame and whose other end extends to the vicinity of the bottom member.

Hereinafter, a specific embodiment of the present invention will be described based on FIGS. 1 to 4. Reference numeral 1 denotes a cleaning chamber of a cleaning machine for cleaning objects to be cleaned, and high-pressure liquid is supplied to the cleaning chamber 1 from a liquid supply source (not shown). Reference numeral 2 designates a main body frame of the washing machine having a welded integral structure, and 3 designates a liquid recovery chute main body fixedly supported by the main body frame 2 below the washing chamber 1. The bottom plate (bottom member) 4 of the liquid recovery chute main body 3 is inclined downward from both left and right sides toward the center in FIG. A side wall frame plate frame 5 extends upward and is fixed to the outer peripheral end of the bottom plate 4, and the liquid recovery chute main body 3 is opened upward. An opening 6 is formed in the center of the bottom plate 4. Further, a notch opening 7 is formed in one side of the frame plate 5 so as to be continuous with the opening 6.

Reference numeral 8 denotes a chute portion, and the chute portion 8 extends outside the washer provided facing the opening portion 6 and the notch opening portion 7. This chute section 8 has a function of discharging the dirty liquid after washing the object to be washed out of the washing chamber 1. An inclined plate 9 serving as a slit shielding member is provided at the lower part of the frame plate 5 so as to be inclined downward toward the bottom plate 4. That is, the upper edge of the inclined surface 9 in the width direction is fixed to the frame plate 5 at a required height position, and the lower edge of the inclined surface 9 extends to the vicinity of the bottom plate 4. Between the bottom plate 4 and the inclined plate 9, there is a fourth
As shown in the figure, a slit-shaped nozzle 10 is formed by a bottom plate 4, an inclined plate 9, and a frame plate 5, with a necessary small gap t. 11 is a liquid supply port for supplying liquid to the slit-like nozzle 10, and the liquid supply port 11 is connected to the above-mentioned liquid supply source.

Next, the operation of the liquid recovery chute device configured as described above will be explained. When a predetermined cleaning process is started, the object to be cleaned is first transported into the cleaning chamber 1 of the cleaning machine. Next, high-pressure liquid is supplied from the liquid supply source to the cleaning chamber 1 to clean the object to be cleaned, and at the same time, the high-pressure liquid is supplied to the liquid supply port 11.
It is also supplied to the slit-shaped nozzle 10 through the . The high-pressure liquid supplied to the slit-shaped nozzle 10 is ejected from the inclined upper end of the bottom plate 4 toward the center, as shown by the arrow in FIG. Here, during the cleaning process, dirty liquid containing foreign matter such as chips of the object to be cleaned falls onto the bottom plate 4 from beginning to end, but the high-pressure liquid spouted toward the bottom plate 4 from the slit-shaped nozzle 10 Foreign matter in the dirty liquid adhering to the bottom plate 4 is quickly removed, thereby preventing the foreign matter such as chips from adhering to the bottom plate 4. When the predetermined cleaning process is completed in the cleaning chamber 1, the cleaning chamber 1 and the liquid supply port 11 are
The supply of high-pressure liquid to is stopped, and then the cleaned object is transported to the next process and the cleaning process is completed.

In the embodiment, the liquid supply source to the cleaning chamber 1 and the liquid supply source to the slit-shaped nozzle 10 are provided in common, but the liquid supply source to the slit-shaped nozzle 10 and the liquid supply to the cleaning chamber 1 are In this case, there is an advantage that foreign substances such as chips adhering to the bottom plate 4 of the liquid recovery chute body 3 can be cleaned at any time without being restricted during the cleaning process.

As explained above, according to the present invention, the bottom member is cleaned by high-pressure liquid jetted from the slit-shaped nozzle formed at the slanted upper end of the bottom member of the liquid recovery chute main body, so that foreign substances such as chips in the waste liquid are cleaned. Adhesion to the bottom member can be quickly and efficiently removed, and the labor and time required for cleaning by an operator's input after the end of the cleaning process or before the start of the cleaning process, which is required in the past, can be eliminated.
