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 to be solved by the invention] By the way, one of the drawbacks of such conventional devices is that the ashtray insertion slot is always open and the dirty interior is unsightly, but it is difficult to just open the lid. If this happens, it will take time to open and close the opening, making it troublesome to use. In addition, with conventional equipment,
There is the hassle of having to press a button to perform tasks such as cleaning and drying, and it is a burden on refueling workers, especially at gas stations, who have to perform these operations during limited refueling hours.

[Means for Solving the Problems] This invention was made in response to these problems, and includes a cleaning chamber with a door in the ashtray insertion slot, a water outlet for discharging cleaning water into the cleaning chamber, and compressed air. an air cylinder that opens and closes the door; a switch that opens and closes according to the displacement of the door; This problem is solved by providing a solenoid valve for controlling the introduction of compressed air, and detecting that the door is opened to open the door and start cleaning.

[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 on the upper side, 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 port that penetrates through the inside of the water discharge nozzle 29. 2
5 and opens upward by a predetermined distance,
An air nozzle 34 that communicates with an air pressure source 33 such as a compressor via an air hose 31 and a solenoid valve 32.
It is composed of. In addition, the water spray nozzle 2
In addition to the water outlet 25, the water outlet 9 has a plurality of indoor cleaning water outlets 35 drilled around the water outlet 25 at positions along the bottom surface of the cleaning chamber 20. On the door 23,
A switch 36 that detects the opening/closing operation of the door 23 at a certain angle or more and switches the switch 36 and an air cylinder 37 that opens/closes the door 23 are attached. The air cylinder 37 is 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 . A controller 38 is activated by the switch 36 to cut off the power to the solenoid valves 27 and 32. 39
is a 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 cleaned 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.

Note that this invention is not limited to the above embodiment, and the cleaning nozzle 21 may be constructed in the same manner as the conventional device shown in FIG. It can be carried out without any problems.

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

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.

The door opens automatically with just a slight push, such as pressing lightly with an ashtray, allowing for smooth use as before without the hassle of opening and closing the door.

Just open the door and the cleaning will start automatically.
There is no need to manually operate each one as in the past,
The work burden on workers can be greatly reduced.

The air nozzle and air cylinder are supplied with compressed air by a single solenoid valve, and when the solenoid valve closes, the air pressure inside the air cylinder is released from the air nozzle, so an expensive atmosphere release port is required. There is no need to use a solenoid valve, etc., and the structure can be configured at an extremely low cost.
