Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a pressure washer.

[Conventional technology]

Generally, a washing machine uses an electric motor to rotate rotary blades installed at the bottom of the washing tub, and the laundry items placed in the washing tub are rocked and rotated together with water or hot water and detergent, so that they adhere to the laundry items. It is designed to remove dirt.

[Problem that the invention seeks to solve]

Since the washing machine mentioned above uses electrical energy, there are many mechanical parts that are driven by the same energy.
The weight and volume are large, therefore, a large installation space is required, and it is not easy to carry, and the operating noise is high, which is felt as noise.
Even when the amount of laundry is small, it takes a long time to wash and the electricity bill is relatively high, making it uneconomical.

[Means for solving problems]

The present invention aims to provide a pressure-type washing machine that solves the above-mentioned problems, and its features include, firstly, a container having an inlet for the laundry to be washed; The present invention has a structure including a lid body that supports the container, and a support base that rotatably supports the container.

Second, the present invention provides a container having an inlet for laundry to be washed, a check valve for injecting air into the container, a lid for sealing the inlet, and a lid for rotating the container. The present invention is characterized in that it has a structure including a support base that supports freely.

[Effect]

According to the first configuration, the items to be washed are placed in the container, warm water and detergent are added, and the container opening is closed with a lid;
When the container is rotated, the pressure inside the container increases due to the steam generated from the hot water, and the hot water and detergent work well on the laundry items.The rotational movement causes the laundry items to rotate and vibrate, causing the laundry items to be washed. Dirt adhering to the surface is quickly removed.

Further, according to the second configuration, instead of generating steam using hot water, the items to be washed are put into the container, water and detergent are added, the input port of the container is closed with a lid, and then a back check is performed. By injecting air into the container from the valve and increasing the pressure inside the container, water and detergent can be effectively applied to the laundry items, and combined with the rotational movement of the container, this effectively removes dirt from the laundry items. Can be removed.

The washing machine of the present invention has any of the configurations described above.
Since there are no electrically driven mechanical parts like in conventional washing machines, there is no need to use electrical energy, no noise is generated during use, and the overall volume and weight are reduced.

〔Example〕

The illustrated embodiment incorporates the two inventions characterized as described above, in which a container 1 for accommodating laundry items to be washed has step portions 2A and 3A formed approximately in the middle thereof, respectively. The upper frame 2 and the lower frame 3 are tied together at each end, and a reinforcing band 4 is wrapped around them, and the other end of the upper frame 2 is formed with an inlet 2B for loading items to be washed. A rising portion 2C is formed, and a ring 5 for coupling with a lid body, which will be described later, is fitted onto the rising portion 2C. The ring 5 is formed with protrusions 5A extending in the circumferential direction at intervals of, for example, 120 degrees, and at least one of the protrusions 5A has a hanging portion 5B extending downward.

Approximately in the middle of the container 1, that is, at the joint between the upper frame 2 and the lower frame 3, there is provided an annular plate 6 with a plurality of through holes 6A, and an opening 6B in the center of the annular plate 6 allows the laundry to be put into the container 1 through the central opening 6B. can move freely during the washing operation, which will be described later.

A check valve 7 is attached to the lower part of the lower frame 3 to prevent backflow of air when air is injected into the container 1 sealed by a lid described later and to maintain the inside of the container 1 in a high pressure state. That is, the check valve 7 includes a valve pipe 8 that is inserted into a valve mounting hole 3B formed in the lower frame 3 and attached to the lower frame 3, and a through hole 9A and a valve pipe 8 that is fixed to one end of the interior of the container 1. A seat plate 9 forming a spring receiver 9B and a valve body 10 that can freely move toward and away from a valve seat 8A formed on a valve pipe 8.
and the valve body 1 is interposed between the spring receiver 9B and the valve body 1o.
0 to the valve seat 8A, and a cap nut 13 with a sealant 12 screwed onto the other end of the valve pipe 8.

Among these elements, one or both of the valve body 1o and the cap nut 13 with the sealing material 11 can be inserted into the container 1 by injecting air.
Rather than increasing the internal pressure, it also functions to provide airtightness to the container 1 when the pressure inside the container 1 is increased by the steam generated by hot water and maintained at a high pressure state. .

On the other hand, the lid body 14 has an outer lid 15 formed with a female thread 15A in the center, a notch in the lower peripheral part corresponding to the protrusion 5A of the ring 5, and an overhang part 15B pushed out inward. Inside, the container 1 side is convex and the center has a through hole 16A.
The inner lid 18, which is made up of a circular plate 16 formed with a circular plate 16 and an annular packing member 17 made of, for example, rubber, is attached to the peripheral edge of the circular plate 16 so as to come into contact with the upper peripheral edge of the rising portion 2c of the container 1. The opening adjustment screw 2o with a knob 19 attached thereto is screwed into the female screw 15'A of the outer cover 15, and its tip is opposed to the through hole 16A of the disc 16. be.

The container 1 has a supporting shaft 21.
22 are inserted into bearing holes 23A and 23B formed in a support base 23 made of a pipe or a round bar, for example, and are rotatably supported on the support base 23, and can be freely attached and detached to the end of one of the support shafts 21 with a set screw 24. It can be manually rotated by means of a handle 25 coupled to the handle 25. In addition, a small hole 22A is provided in the other one of the support shafts 22, and the tip of a hook 26 rotatably attached to the support base 23 is engaged with the small hole 22A so that the container 1 can be stopped at the position shown in the figure. It's Nishide.

The usage and function of this washing machine will be described below in relation to the above two inventions. That is, in the first invention, after the laundry is put into the container 1, hot water and detergent are added depending on the type, amount, and dirtiness of the laundry, and the lid 14 is fitted onto the ring 5.

In that case, the stepped portions 2A and 3A of the container 1 are used as a guide for the amount of laundry to be washed and the amount of hot water to be poured. The lid body 14 is inserted into the ring 5 so that its protruding part 15B is located below the protrusion 5A of the ring 5, and one of the protruding parts 15B is in contact with the hanging part 5B of the protrusion 51A. Position correctly in the circumferential direction. Turn the knob 19 and tighten the adjustment screw 20 to secure the seal member 17 of the inner lid 18 to the rising part 2C of the container 1.
The tip of the adjusting screw 20 is pressed into the through hole 16 of the disc 16.
When A is closed, the container 1 will be in a sealed state. In this state, attach the hook 26 to the small hole 22A of the support shaft 22.
Then, the container 1 is rotated by the handle 25 at a relatively slow speed depending on the type of laundry, dirt, etc. As a result, the articles to be washed get caught on the annular plate 6 while the container 1 is rotating, and then fall off the annular plate 6, repeating this motion. Further, hot water and the like move inside the container 1 through the through hole 6A of the annular plate 6 while the container 1 is rotating. On the other hand, the pressure inside the container I increases due to the steam generated from the hot water, resulting in a high-pressure state, so to speak, where compressed steam is generated. The detergent and steam penetrate deep enough and blend well, so dirt is broken down in a short time and removed reliably. Moreover, due to the synergistic action of the pressure inside the container, compressed steam, and detergent, the washing time is short, so the fabric is not damaged. After the rotation operation according to the type, amount, etc. of the items to be washed, the rotation of the container 1 is stopped and the hook 26 is locked in the small hole 22A of the support shaft 22. In this state, when the adjusting screw 20 is gradually loosened, pressure escapes from between the through hole 16A and the rising portion 2C of the disc 16 and the packing member 17. After the pressure is completely released, the lid 14 is removed and the laundry is taken out. Since the stains on the items to be washed have already been removed in the container 1, it is only necessary to rinse them as appropriate. Tables 1 and 2 shown below are examples of washing methods using this washing machine. In Table 1, the washing time is based on the assumption that one rotation of the handle is approximately 1 second.

Table 1 Table 2 Also, regarding the second invention, water and detergent are put into the container 1, the container is sealed with the lid 14, and the 1i
Remove the cap nut 13 from the valve pipe 8 using L+. Next, the tip of a conduit connected to a pump (not shown) is connected to the valve pipe 8, and air is blown into the valve pipe 8 by the pump. Then, the air pushes up the valve body 10 upward in FIG. 4 against the spring 11, and enters the container 1 through the space between the valve pipe 8 and the valve seat 8A and through the through hole 9A of the seat plate 9. Put the inside of 1 into a high pressure state. In that case, in order to prevent the container 1 from being damaged by pressure due to excessive air blowing, in other words, for safety, a pressure gauge is installed on the pump side, and the material, shape, capacity, etc. of the container, and the According to an actual measurement example, air is blown into the capacity 1 at a pressure that is below the pressure value appropriate for the amount of water, detergent, type and amount of laundry items, etc. According to an actual measurement example, the maximum amount of laundry was 1.8 kg. The main body is aluminum, the lid body is stainless steel, and the main body dimensions are medium 38.5 x depth 35. For containers with an OX height of 38.0, the maximum safe pressure inside the container is approximately 0.48 kg.
/c+a.

1 After that, remove the conduit and insert a bag 13 into the valve pipe 8.
After tightening, the hook 26 is removed from the spindle 22, and the container 1 is rotated using the handle 25 as described above. As in the case of the first invention, the laundry to be washed is placed in the container under high pressure. 1, repeating the same movements as in the above case, the water and detergent penetrate deep enough into the laundry to be thoroughly absorbed, so that the dirt is similarly broken down in a short time and removed reliably. The method for releasing the pressure inside the container, rinsing, etc. is the same as described above.

〔Effect of the invention〕

According to the present invention, it is possible to easily, ie, economically, manually without using expensive energy such as electric energy, and moreover,
It is suitable for washing small amounts of laundry as it can reliably and quickly remove dirt from the laundry items, and since the rotating noise during use is quiet, there is no discomfort due to noise, and the simple structure makes it compact. Since it is possible to reduce the size and weight of the washing machine, and therefore requires less space for installation or storage, it is possible to provide a washing machine that is convenient to carry when traveling, for example. In particular, if the washing machine according to the second invention uses an air pump for tires such as bicycles, the above-mentioned washing effect can be obtained by applying pressure even when the washing water is water instead of hot water. It is also suitable for carrying when camping outdoors where hot water is not available.

In addition, in the present invention, the same effect as described above can be obtained by mixing a chemical agent into the washing water and increasing the pressure inside the container by the chemical reaction.
