Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a washing machine, and more particularly to a washing machine that sprays a high-pressure water stream onto objects to be washed on a conveyor.

(Prior Art) In order to effectively utilize the high-pressure water flow ejected from a small number of nozzles provided below a conveyor, the nozzles are horizontally reciprocated using a crank or the like in a direction perpendicular to the conveyor.

(The problem that the idea aims to solve) However, conventional washing machines have the following problems.

Since the horizontal speed of the nozzles at both edges of the conveyor is slow, there is a waste of cleaning that is unnecessary or more than sufficient. Also,
Even if the nozzles are moved back and forth at a constant speed, at both edges of the conveyor or at both ends of the left-right deflection of each nozzle, the trajectory of the ejected water flow drawn on the conveyor surface alternates between dense areas and rough areas. As a result, the cleaning power of high-pressure water becomes uneven and wasteful. This goes against the technical challenge of cleaning the entire surface of the conveyor with uniform cleaning power using a limited number of nozzles, and has the disadvantage that uniform cleaning cannot be achieved within a limited time. .

The present invention solves these problems and provides a highly efficient cleaning machine that eliminates unevenness in cleaning power and eliminates waste.

(Means for Solving the Problems) A washing machine according to the present invention includes the following configuration in order to solve the following problems.

In the washing tM14, in which the water stream 12 ejected toward the dishes, plates, etc. to be washed on the conveyor 10 is reciprocated in a direction perpendicular to the conveyor 10, the nozzle 16 and the conveyor are moved at high speeds during reciprocating. The nozzle 16 is connected to the conveyor 1 in order to shorten the distance between the water flow 12 of 10 and the area where the water flow 12 hits, and to increase the distance in areas where the speed during reciprocating is low.
It is characterized by adopting a configuration that allows it to reciprocate even with respect to the zero plane.

(Function) As the nozzles 16 move away from the conveyor surface as they approach both ends of the left-right deflection of each nozzle, the water flow I2 ejected from the nozzles 16 hits the conveyor surface in a spread state, slowing down the movement of the nozzles 16. Alternatively, at locations where the nozzle 16 trajectories are crowded, the cleaning surface is expanded and cleaning takes a relatively long time, and at intermediate locations where the nozzle moves quickly, the nozzle 16 is brought closer to the conveyor surface so that the water stream 12 hits the surface. The surface is squeezed and powerful cleaning power is applied for a relatively short time.

(Example) Preferred examples embodying the present invention will be described below in detail with reference to the drawings.

In Figure 1, a conveyor 1 flowing toward the front left
0 is a conveyor that can pass the jet stream from below, which is combined in a mesh shape, and a pressure-resistant pipe 18 that is orthogonal to the conveyor 10 is horizontally arranged below the conveyor 10. Approximately three to five upward nozzles 16 are provided on the upper surface of the pressure-resistant pipe 8. Both ends of the pressure-resistant pipe 18 are pivotally supported by discs 20 and 20 that stand in a direction perpendicular to the conveyor 10.
A drive shaft 22 that reciprocates in the left and right direction in synchronization with 0.20
is driven from a motor 24 via a crank 26. This motor 24 and a motor 30 that drives the conveyor 10 are driven synchronously using an inverter 32.

Each nozzle 16 is pulled downward by a disk 20, 20 near both ends of its left and right reciprocation.

FIG. 3 shows the state of the water flow 12 when the pressure-resistant pipe 18 and the nozzle 16 are in the raised position H and the lowered position. That is, in the lowered position, the water flow 1 from the nozzle 16
2 cleans a wide area with low cleaning density over a long period of time, and during high-speed movement in the middle of left and right reciprocation (ascending position H), nozzle 1G comes closest to the conveyor surface and does not wash for a short time. also has strong cleaning power (high cleaning density)
.

FIG. 2 is a plan view showing the water volume distribution of the conveyor 10. In this figure, the serpentine line on the conveyor 10 is the nozzle 16 on the conveyor 10 that follows the movement of the nozzle 16 and the conveyor 10.
The large circle 12a indicates the low cleaning density state at the lowering position iL of the nozzle 16, and the small circle 12b indicates the low cleaning density state of the nozzle 12.
This shows the high cleaning density state at the elevated position H. As a result, uniform cleaning power can be applied over the entire surface, which is larger than before.

In another embodiment, as shown in FIG. 4, multiple rows of pressure-resistant pipes 18 with nozzles, such as three rows, are arranged, and a circular plate 20.
A connecting rod 34 synchronizing 20 can be connected between the axes 36.36 of the disc 20.20.

Furthermore, as shown in FIG. 5, pipes with nozzles are arranged above and below the conveyor 10, and the upper and lower pressure-resistant pipes 1
A connecting rod 34 synchronizing 8 can be connected between the discs 20.20.

In yet another embodiment, as shown in FIG. 6, a single pressure-resistant pipe 18 is located in the center of the conveyor 10 horizontally along the conveyor 10, and the pressure-resistant pipe 18 is swung left and right about its axis. Even in a direction in which the distance between the conveyor 10 and the nozzle 16 is not changed in a configuration in which the nozzle 16 on the pressure-resistant pipe 18 is moved, the distance between the nozzle 16 and the conveyor 10 increases as the end edges of the conveyor 10 are approached, so that the water flow 12
spreads and the cleaning density decreases, and cleaning can be performed for a relatively long time to compensate for the cleaning density. When using this direction, the direction of the nozzle changes, creating a blind spot on the inner wall on the center side of the tableware near both edges of the conveyor.In other words, since the inner wall of the lunch box etc. is washed, it is recommended to combine it with other methods. Or, it is preferable to use it exclusively for dishes.

Various types of nozzles can be used for the nozzle 16, and the mechanism for moving the nozzle in the vertical direction can be a wide variety of mechanisms, so it cannot be specified, but in addition to a crank, links, cams, diagonal disks, etc. are preferably used. can do.

(Effects of the Invention) As described above, according to the present invention, the speed of the nozzle and the restriction of the water jet ejected from the nozzle are related by simply moving the nozzle position up and down, and the conveyor can be spread over the entire surface of the conveyor, and moreover, more than ever before. Uniform cleaning power can be applied over a wide area. Therefore, it is particularly effective in cleaning machines where the number of nozzles with a limited flow rate cannot be increased by using an ultra-high pressure nozzle actuator.

Although the present invention has been variously explained above with reference to preferred embodiments, the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. It is.
