By the way, in such a portable cleaning device, the use of a synthetic resin housing formed by molding reduces the weight and facilitates carrying. However, a mold is used in the molding process, and this mold is expensive. When the production quantity is large, the cost of the mold does not greatly affect the cost of the housing. If the amount is small, the cost of the mold greatly affects the cost of the housing, and the portable cleaning device becomes expensive.

Accordingly, the present invention provides a lightweight and inexpensive portable cleaning device.

The mounting mechanism of the motor 0 and the motor 31 is omitted.

The upper plate 21, the bottom plate 22, the side plate 23 on the water supply pipe side, the side plate 24 on the water supply pipe side, and the two outer plates 25,
Reference numeral 26 denotes a structure formed by using a foamed resin plate. A foamed resin plate having a predetermined size is cut, for example, by irradiating a laser beam, or a water cutter, which cuts by blowing water at a high pressure. Since the mold can be easily removed by using a mold, a mold is not required.

The upper plate 21 and the bottom plate 2 thus configured
2. Side plate 23 on the water supply pipe side, side plates 24 and 2 on the water supply pipe side
The two outer plates 25 and 26 have the engaging projections 75G of the side plates 23 inserted into the engaging holes 75H of the upper plate 21 and the upper plates 21 and 26, respectively.
The engagement projection 76G of the side plate 24 is inserted into the engagement hole 76H. Further, the engagement protrusion 81G of the side plate 23 is inserted into the engagement hole 81H of the bottom plate 22, and the engagement hole 8
The engagement projection 82G of the side plate 24 is inserted into 2H. Thereafter, the engagement holes 71H, 72H, 77H, 78 of the outer plate 25 are formed.
H, 83H, 85H, the engaging projections 71G, 7
2G, the engagement projections 77G and 78G of the bottom plate 22, the engagement projection 83G of the side plate 23, and the engagement projection 85G of the side plate 24 are inserted. Further, the engagement holes 73H, 74H,
At 79H, 80H, 84H, 86H, engaging projections 73G, 74G of the upper plate 21 and engaging projections 79G, 80G of the bottom plate 22 are provided.

Here, when the engaging protrusion is inserted into the engaging hole, for example, when the engaging protrusion 75G of the side plate 23 is inserted into the engaging hole 75H of the upper plate 21, the engaging protrusion 75G is formed. The distance between the end surface LKe of the engaging portion LK and the side surface 23a is substantially equal to the thickness of the upper plate 21 in which the engaging hole 75H is formed as shown in FIG. When the mating projection 75G is inserted, the rattling is reduced. Also, as shown in FIG. 6 which is a cross-sectional view taken along line II ′ of FIG. 5, the engaging portion LK formed on the engaging protrusion 75G protrudes from the surface of the side plate 23, and
Since the end surface LKe of the engaging portion LK of G comes into contact with the surface of the upper plate 21, it is possible to prevent the engaging projection 75G of the side plate 23 from coming off the engaging hole 75H of the upper plate 21.

The engagement protrusion is inserted into the other engagement hole, and the engagement protrusion formed on the engagement protrusion prevents the engagement protrusion from coming off from the engagement hole. Since the gap between the end face and the side face of the engaging portion formed in the above is adjusted to reduce the backlash, it is possible to obtain a lightweight and robust housing. 2 and 3
Although it is assumed that the engaging portion formed on the engaging protrusion protrudes, the engaging protrusion may be disengaged from the engaging hole by inserting the engaging protrusion into the engaging hole and then projecting the engaging portion. May be prevented.

As described above, according to the above-described embodiment,
An upper plate 21, a bottom plate 22, side plates 23, 24 and an outer plate 25,
Since 26 is formed using a foaming resin such as a foamed vinyl chloride plate, the weight of the portable cleaning device 10 can be reduced. Further, since the upper plate 21, the bottom plate 22, the side plates 23 and 24, and the outer plates 25 and 26 are cut from a foamed resin plate of a predetermined size, a mold is not required, and the cost of the portable cleaning device can be reduced. it can. Further, it is possible to easily assemble only by inserting the engagement projections corresponding to the engagement holes provided in the upper plate 21, the bottom plate 22, the side plates 23, 24, and the outer plates 25, 26, and to obtain the end face of the engagement portion LK. Since the LKe comes into contact with the plate surface on which the engagement hole is formed, the engagement protrusion is prevented from coming off, so that the housing of the apparatus main body 20 can be made robust.
Further, since the recesses 27 are formed in the handles 25a, 26a of the outer plates 25, 26, the handles 25a, 26a are bent, for example, when the portable cleaning device is carried, so that the handles 25a, 26a can be easily grasped. In other words, the portable cleaning device can be easily carried. The positions and numbers of the engagement projections, the positions and numbers of the engagement holes, the shapes of the outer plates, and the like are merely examples, and are not limited to the above-described embodiment.

[0033]

According to the present invention, since the upper plate, the bottom plate, the side plates, and the outer plate constituting the housing of the portable cleaning device are formed using a foamable resin, the weight of the portable cleaning device can be reduced. be able to. Also, the top plate, bottom plate, side plate and outer plate are
Since the mold is formed by being cut out from the foamable resin plate, a mold is not required unlike a molding process, and the portable cleaning device can be made inexpensive. Further, since one or both of the engaging projections and the engaging holes are provided on the upper plate, the bottom plate, the side plates, and the outer plate, the assembly can be easily performed only by inserting the engaging protrusions into the engaging holes. Further, since the engaging projection is provided with a locking portion which comes into contact with the plate surface on which the engaging hole is formed to prevent the engaging projection from coming off, the engaging protrusion inserted into the engaging hole is locked. The case is fixed by the portion to make the case robust. Further, when the portable cleaning device is carried, the handle portion can be bent, so that the portable cleaning device can be easily carried.
