Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a device installed at gas stations, automobile repair shops, etc., for cleaning ashtrays and the like attached to automobiles.

[Conventional Example] A conventional device will be explained with reference to FIG. Reference numeral 1 denotes a cleaning device main body, which has a cleaning chamber 2 formed in its upper part, and a water storage tank 4 that receives water from a water source 3 such as a tap at its lower part. 5 is a cleaning nozzle, and water storage tank 4
A water supply port 7 is provided which communicates with the water supply port 7 via a solenoid valve 6, and compressed air is introduced from an air pressure source 9 such as a compressor into the outer periphery of the water supply port 7 via a solenoid valve 8, and this compressed air is introduced from a nozzle port 10. The water is ejected to suck up the water in the tank 4 and wash the ashtray. 11
is a switch that opens and closes the solenoid valves 6 and 8,
It is equipped with a cleaning button and a drying button. First, the cleaning button is pressed to open both solenoid valves 6 and 8, and the ashtray inserted into the cleaning chamber is sprayed with cleaning water energized by compressed air to clean it. Next, the drying button is pressed to open only the solenoid valve 8, and compressed air is blown onto the washed ashtray to dry it.

[Problems that the invention aims to solve] By the way, with such conventional equipment, cleaning and
Each worker has to press a button to perform tasks such as drying, which is cumbersome, and especially at gas stations, refueling workers are burdened with having to perform such operations during limited refueling hours. Further, although the cleaning to drying process can normally be completed in a short time of 5 to 10 seconds, the actual operation by the operator tends to take a long time, resulting in wasted cleaning water and the like.

[Means for Solving the Problems] This invention was made in response to these problems, and includes a cleaning chamber equipped with a door in the ashtray insertion slot, and cleaning water directed toward the ashtray inserted into the cleaning chamber. a first electromagnetic valve for controlling water discharge from the water discharge nozzle; an air nozzle for spraying compressed air toward the ashtray inserted in the washing chamber; and a first electromagnetic valve for controlling water discharge from the water discharge nozzle; a second solenoid valve to be controlled; a switch that opens and closes in accordance with the displacement of the door;
A controller is installed to open the second solenoid valve to provide cleaning for a certain period of time, and then open only the second solenoid valve to provide drying for a certain period of time. The device is constructed so that predetermined cleaning and drying operations can be performed continuously just by inserting the device, thereby solving the above-mentioned problems.

[Example] Hereinafter, the example will be described using FIGS. 2 to 6.

FIG. 2 is an explanatory diagram showing the basic configuration of the embodiment, and FIGS. 3 and 4 are explanatory diagrams of the main parts thereof. Reference numeral 20 denotes a cleaning chamber, which has a cleaning nozzle 21 and a drain port 22 on the bottom, and an ashtray insertion opening 24 with a door 23 on the front. The cleaning nozzle 21 includes a water discharge port 25 at the top, a water discharge nozzle 29 that communicates with a water source 28 having water supply pressure such as a water supply via a water supply hose 26 and a solenoid valve 27, and a water discharge nozzle 29 that penetrates through the water discharge nozzle 29 and discharges water. It is comprised of an air nozzle 34 that projects a predetermined distance upward from the water port 25 and communicates with an air pressure source 33 such as a compressor via an air hose 31 and a solenoid valve 32. In addition to the water outlet 25 in the water outlet nozzle 29, a plurality of water outlets 35 for indoor cleaning are provided around the water outlet 25 in the cleaning chamber 20.
It is perforated along the bottom of the The door 23 includes a switch 36 that detects when the door 23 is opened/closed at a certain angle or more and switches the switch 36 .
An air cylinder 37 for opening and closing is attached. This air cylinder 37 consists of a single-acting cylinder equipped with a spring that biases the door 23 in the closing direction, and receives compressed air from the solenoid valve 32 at the same time as the air nozzle 34 . 3
8 is a controller which is activated by the switch 36 and cuts off the power to the solenoid valves 27 and 32.
Reference numeral 39 is a bedding net provided at the bottom of the cleaning chamber 20.

The operation of the embodiment having the above configuration will be explained below.

The user pushes the door 23 with the ashtray to be washed facing downward. Accordingly, when the door 23 is opened beyond a certain level, the switch 36 is turned on, and the controller 38 first opens both the solenoid valves 27 and 32. This valve opening causes the air cylinder 37 to operate and the door 23 to open.
At the same time as the ashtray is raised to a predetermined position and introduced into the cleaning chamber 2, the cleaning nozzle 21 discharges cleaning water and compressed air from the water discharge ports 25, 35 and the air nozzle 34 all at once. The water discharged from the water outlet 25 is mixed with compressed air discharged from the air nozzle 34 and is energized, and is vigorously blown onto the ashtray to wash away dirt. On the other hand, water outlet 35
The water released from the cleaning chamber 20 spreads along the bottom surface of the cleaning chamber 20, washes away the dirty water scattered downward by the above-mentioned ashtray cleaning, and is discharged from the drain port 22.

After the solenoid valves 27 and 32 are opened, the controller 38 detects that a certain period of time T ₁ (about 1 to 5 seconds) has elapsed and closes only the solenoid valve 27 . Accordingly, the water discharge from the water discharge ports 25 and 35 is stopped, and only the air discharge from the air nozzle 34 continues.
The compressed air discharged from the nozzle 34 scatters water droplets adhering to the ashtray due to the above-mentioned washing, thereby promoting drying of the ashtray.

Thereafter, when the controller 38 detects that a certain period of time T ₂ (about 2 to 8 seconds) has elapsed, the solenoid valve 32 is closed. Along with this, the supply of compressed air was stopped,
When the air discharge from the air nozzle 34 stops, the air pressure applied to the air cylinder 37 is released from the air nozzle 34 through the air hose 31, and the door 23 is closed by the spring provided in the cylinder 37.

The above series of operations are summarized in a flowchart and shown in FIG. In addition, the above timer setting time
T ₁ and T ₂ can be changed by adjusting means (not shown) provided in the controller.

[Effects of the invention] This invention is constructed as described above and has the following effects.

Just open the door and the cleaning will start automatically.
Moreover, since the controller automatically performs cleaning and drying in a series of operations, there is no need for manual operations for each as in the past, and the workload on the operator can be greatly reduced.

Each cleaning and drying operation is performed for a predetermined time given by the controller and is not continued unnecessarily, allowing economical use.

The interior of the cleaning chamber is covered with a door to prevent the dirt inside from being exposed to the outside or to prevent odors from leaking out, so it can be used comfortably at all times.
