Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a cleaning machine that cleans objects to be cleaned by jetting or scattering a cleaning liquid.

stomach! The configuration of the fton example and its problems Conventionally, this fton washing machine has a very common one.
- A washing tank 1 containing objects to be washed as shown in FIG.
There is a nozzle 2 for discharging the liquid 'i-' l+jf, which is rotatably driven by hydraulic power.
3 and pump 4, the cleaning liquid is circulated and applied to the object to be cleaned, and its chemical and mechanical power removes dirt. Further, 5 is a heater for warming the water circulated during washing or rinsing, and 6 is a drain pump. The cleaning process of these cleaning machines is generally performed as shown in FIG. 2A.

As a general process, pre-washing or pre-soaking is performed to assist the main washing process, although it may be omitted in some cases. At the start of the pre-washing shown in I of Figure 2 A, usually cold water is sprayed from the nozzles 2 and 3 using only mechanical force to wash away all the dirt that comes off with the water. It is only meant to make the detergent power work effectively (works only on dirt that has not been removed by water), and has no significant effect on reducing detergent power, labor saving, or time during main washing. In addition, since pre-washing requires large mechanical force (water pressure) during washing, there is a problem of large noise such as the collision sound of motor and pump water. There are methods such as soaking in water (often used during hand washing as shown in No. 2"9B) or applying steam as shown in 11 of Figure 2A. It has the effect of making it easier to remove dirt during the main washing, reducing detergent power, labor saving, and time reduction in the main washing. It's easy to connect.It's true that the thicker the pre-soaking effect, the more labor-saving the main washing as mentioned above will be. However, it is common knowledge that the effect is greater when detergent is added. However, since it uses electrified water, it requires a lot of energy and time to raise the water temperature (C).
)-It does not lead to labor-saving or time-saving.3. Also, when pre-soaking with steam etc., detergent does not enter.The effect is halved and its constituent pitch name)

1. If there is a place (70-80″C or higher) where you can use rice fields
W and t are the same size as the inverted V, making it harder to fall off.
There were 11 problems.

Aspect 1 of the Invention The present invention solves these conventional problems and provides a cleaning machine that saves labor, shortens cleaning time, and reduces noise.

Structure of the Invention The washing machine of the present invention includes a pre-soaking process before the main washing, and the pre-soaking process is performed by foaming the detergent solution and filling or flowing the foam into the washing tank using a color generating device. .

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 3, there is a washing tank 10 that accommodates the objects to be washed, which sprays or splashes the washing liquid onto the dishes while being rotated and driven by hydraulic power.1 Nozzles 11 and 12 apply chemical and mechanical force to the objects to be washed. A pump 1 for pumping water into the cleaning tank 10 and its nozzles 11 and 12.
3 are provided at the lower part of the outside of the cleaning tank 10, respectively. Further, there are four parts 14 at the bottom of the cleaning tank 10, and a heating element 15 is attached to the outer periphery of the four parts 14. Also, from this recess 14, the pump 13 is connected to the pump 13 through the pipe 16.
The water is circulated through the cleaning system 1.
Reference numeral 17 is a blower that generates bubbles by sending air under full pressure to the cleaning liquid stored in the recess 14. A valve 18 is installed in the passage to prevent the liquid from flowing back.
4 has been completed. Reference numeral 19 is an air vent provided above the cleaning tank 10, through which excess foam is also discharged. 20 is a pump for drainage.

Next, the operation will be explained based on the above configuration. Fourth
The figure is a cleaning process diagram, and shows that first, foam pre-soaking is performed at a high temperature of 5° to 60° C., followed by main washing, and then rinse drying. 1 inch, cleaning tank 1
When water accumulates in the recess 14 on the side A, the heating element 15 is automatically energized and the detergent 1 is added at the same time. This detergent is foaming detergent-C. This cleaning solution is heated to 50°C~60″
When the temperature reaches 50°C, the sword 18 opens and the temperature reaches 50°C.
Air heated to ~6o″C is sent by a blower 1γ,
The VC in the cleaning tank 1 is generated sequentially, and the constant VC is continued for 41 hours between the objects to be cleaned. And cleaning tank 1
When the air is completely filled, the bubbles are discharged to the outside from the air vent hole 19 according to the amount of bubbles generated. During this process, the items to be cleaned come into contact with foam containing a high concentration of detergent, which removes dirt, or the foam bursts and deposits a high concentration of detergent on the tableware, which chemically removes the dirt. or weaken the bond. Also, unlike other presoaks (such as soaking), foam is constantly expanding, moving, and bursting, so some mechanical force is also generated, and in foam presoaking, the bonding force of contaminants is is considerably weakened. Next, drain this detergent liquid Ii,
Instead, add detergent (detergent with antifoaming properties) and water using a B-side mixer, heat it with the heating element 15, and move the pump 13.
The cleaning liquid is ejected from the nozzles 11 and 12 and hits the object to be cleaned, thereby performing a main washing process in which dirt is completely removed by chemical and mechanical forces.

In this way, in the case of the embodiment of the present invention, the effect of presoaking is much stronger and dirt is easier to remove compared to conventional prewashing and presoaking, so the detergent power (concentration and alkali It is also possible to reduce the amount of detergent to an extreme extent and make it unnecessary to use detergent. Also mechanical power (injection pressure).

Even if you reduce the amount of water (water amount) or lower the temperature of the cleaning solution to a certain extent, it can be completely washed. At the same time, the time between 11 and 11 can also be shortened, which all contributes to labor savings. Also, if you lower the water pressure or increase the water volume a little, CJ,
Small heating elements, pumps, and motors can be used, which reduces noise, reduces cost, and saves space and energy.

As another example, as shown in Figure 5, after adding detergent l and performing foam pre-soaking, without draining the water, simply remove the colorant and add water. In other words, compared to supplying and draining water during the transition from pre-soaking to main washing and raising the temperature with a heating element, the time for draining water and the amount of heat required for the water can be reduced.
Furthermore, time can be shortened.

As is clear from the effects of the invention L1jα) and the examples, the washing machine 1 of the present invention! 1! By pre-soaking with foam in the pre-washing process, (1) Compared to the conventional method, the entire object to be cleaned is covered with a small amount of high-concentration cleaning liquid during pre-soaking. It is possible to cross the cloth, and it also requires some mechanical force.It has a great effect of weakening the bonding force of the fibers, which saves labor and time during main washing.

(Kon) Pre-soaking with foam makes almost no noise, and even during the main washing, water noise, pump noise, and motor noise are eliminated (cleaning is possible even with a weak one), and a low-noise washer is used. It is possible.

(You don't have to use the water from the sea cucumber, so you can expect it to have a water-saving effect.

(4) Since the items to be cleaned can be arranged in a high-density manner,
The overall size can be reduced, and costs can also be reduced.
