Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing apparatus for washing by spraying hot water, and more particularly, to a washing apparatus which has a hot water spraying mechanism, wherein a nozzle at the tip of a flexible hose extending from a housing having a built-in lower body is directed toward a washing object. The present invention relates to a cleaning device for spraying water for cleaning.

[0002]

2. Description of the Related Art Referring to FIG. 2 showing an embodiment of the present invention, a conventional cleaning apparatus of this kind includes a heating means 1 for heating water and a pump for supplying water to the heating means 1 by pressurizing the water. 2. Guide the hot water sent from the heating means 1 to the nozzle 3
A hot water injection mechanism 5 is constituted by a flexible hose 4 which jets out of the hot water injection mechanism 5, and the heating means 1, the pump 2 of the hot water injection mechanism 5 and the control unit 6 of the hot water injection mechanism 5 are accommodated in a housing 7. ing. The flexible hose 4 extends from the housing 7 and is wound around a reel (not shown) outside the housing 7 when not in use, or wound around a hose hook outside the housing 7. The casing 7 is provided with a caster 42 as shown in FIG. 1 and can move freely. After moving to a predetermined position corresponding to the washing area, the flexible hose 4 is stretched to extend the nozzle 3 within its length range. By changing the position and the direction of, the housing 7 can be washed without drawing around.

[0003]

However, the flexible hose 4 is easily stained by being routed on a wet and dirty floor, and the nozzle 3 is also easily stained because it has many details. In addition, the flexible hose 4 and the nozzle 3 are easily contaminated with dust and the like even in the state of being wound around the reel or the state of being wound around the hose. Therefore, it is difficult to keep the flexible hose 4 and the nozzle 3 particularly clean, and the dirt increases with time. Therefore, in the conventional handling system in which the flexible hose 4 is put together outside the housing 7, the appearance becomes relatively difficult to see relatively early. In addition, in fields such as medical facilities and food processing,
If the flexible hose 4 in the wound state or the wound state is used as a breeding place for various bacteria, there is a problem if the flexible hose 4 in the wound state or the wound state is used for an application in which washing accompanied by sterilization with hot water of 0 ° C. or more is performed. G. FIG. M. PH A. C. C. P hygiene standards cannot be met.

According to these hygiene standards, there is an obligation to sterilize in an ultraviolet irradiation chamber after use, for example, from the end of work on the day to the start of work on the next day. The flexible hose is easily deteriorated by ultraviolet irradiation, and its life is shortened. The above-described problems of propagation of various bacteria and deterioration due to irradiation with ultraviolet rays are the same in the operation unit having the operation buttons made of resin provided outside the housing 7.

An object of the present invention is to provide a cleaning apparatus which is hardly soiled, can be sterilized without any problem, and is easy to use.

[0006]

In order to achieve the above object, a cleaning apparatus according to the present invention comprises a heating means for heating water, a pump for pressurizing and supplying water to the heating means, and a pump which is fed from the heating means. The minimum size that accommodates each of a flexible hose that guides hot water to be ejected from a nozzle, a reel that winds the flexible hose, a heating unit, and an electrical control unit of a pump in a housing, and that can house the nozzle in the housing. And a retractable structure having a maximum size that cannot be accommodated in the housing, and a closed position that is substantially flush with the outer peripheral surface of the housing,
The reel is supported by a support member that is opened and closed between an open position that is pulled out from the peripheral wall by a predetermined amount, and a flexible hose is wound on the reel and a nozzle that is reduced to a minimum size, along with the opening and closing of the support member. The main feature is that they can be taken in and out of the housing.

[0007] In such a configuration, all of the flexible hose including the heating means, the pump, and the nozzle forming the hot water injection mechanism are housed in the housing together with the control unit, so that the flexible hose and the nozzle which are easily contaminated are not used. In this state, it is possible to prevent the dust and the like from adhering to the outside and the germs from adhering and growing. Further, since the flexible hose is wound and housed on a reel on the support member which is opened to the predetermined position with respect to the housing, the flexible hose is pulled out simply by setting the support member to the open position without being disturbed. Can be unwound and wound up, and can be handled in the same manner as in the conventional case of being put together outside the housing, and is easy to use. at the same time,
The flexible hose wound on the drawn reel was sprayed with hot water sprayed from its own nozzle, sterilized and cleaned together with the support member and the inside of the housing, and then sterilized and cleaned with a flexible hose by closing the support member. The portion can be immediately accommodated in the housing without touching the part, and the sanitary property is also improved in this aspect, and the usability is good. Also, when the support member is closed, it becomes substantially flush with the peripheral wall of the housing, so that there is no detail between the support member and the housing,
Along with the whole hot water injection mechanism being housed in the housing,
The outer surface of the housing is simple and there is no blind spot when sterilized by UV irradiation, and sterilization is perfect, so sanitation is improved on this surface, and UV irradiation deteriorates the flexible hose. Such problems are also solved.
In addition, the nozzle has an expandable structure and is smaller than the housing, ensuring the minimum size that can be accommodated in it, and also the maximum size larger than the housing, so the maximum length from the hand holding the nozzle to the tip of the nozzle The length can be set to a sufficient length exceeding the size of the housing without affecting the housing so that the work can be easily performed.

In this case, the support member or the one support member that is opened and closed between a closed position that is substantially flush with the outer surface of the peripheral wall of the housing and an open position that is pulled out from the peripheral wall by a predetermined amount, When the operation unit of the control unit is supported, and the operation unit is moved into and out of the housing with opening and closing of the supported support member, the operation unit is also easy to use like a flexible hose or nozzle, In addition, the problem of hygiene caused by the formation of the detail portion can be solved similarly in the case of the nozzle, and the hygiene can be further improved. In addition, it is possible to avoid deterioration due to ultraviolet irradiation of a push button or the like of the operation unit.

If the support member for supporting the reel and the support member for supporting the operation section are separate, the operation in which hot water is supported by another support member to wash the flexible hose wound on the reel is used. It is possible to prevent the hot water from adversely affecting electric devices and equipment around the operation unit.

The support member supporting the operating portion is set to have a smaller opening stroke than the support member supporting the reel, and is urged toward the closing position, so that the support member supporting the reel is opened at the final stage. In the configuration in which the support member supporting the operation unit is interlocked and opened so that each support member is simultaneously opened, the operation unit is pulled out more than necessary and obstructs the surroundings. It is easy to prevent accidental touching and causing erroneous operation or failure. Moreover, even if there are two support members and the opening strokes are different, the other opens in synchronization with the opening of one and opens later with the opposition to the urging, and ends simultaneously. One end can be closed after the first end is closed in conjunction with the urging force, and only one of the support members needs to be opened and closed, so that it is easy to use.

When the support member supporting the operation section is supported so that it is substantially upward at the upper end, the operation section is easily accessible and easy to operate.

The support member is hinged so that it can be opened and closed with respect to the lower edge of the opening that fits when the support member is closed to be substantially flush with the peripheral wall of the housing. With the box shape, it is possible to reduce the volume toward the lower hinge connection part while securing the volume necessary for supporting the reel and supporting the operation unit at the top, so that the volume of the entire box is reduced In particular, make the reels and operating parts sufficiently drawable or housed without reducing the space for installing the heating means, pumps, drive motors, control equipment, and other related equipment such as the heating means installed on the bottom of the housing, especially at the bottom. The opening / closing stroke can be satisfied, and the housing can be prevented from becoming large. In addition, since the support member has a box shape,
When supporting the reel, it is suitable to wash the flexible hose in the wound state with hot water and to prevent hot water from scattering outside the required area. It is possible to prevent hot water and improper external force from being applied to the electrical relationship.

When the supporting member supporting the reel has a box shape opened upward and a drain port is provided at a lower portion, the flexible hose wound on the reel is washed with hot water. Since the hot water that has been collected can be collected at a predetermined location and discharged for processing, the safety of the device and the worker in handling the hot water can be improved.

[0014] A supporting member supporting the reel has a box shape opened upward, and has a side wall that is open to the outside at the open position, a reel surface that has a side-to-side rotating shaft cantilever supported on the opposite side wall, and At least a reel opening which is cut out at least in a substantially opposing area is provided, and assuming that an operation handle is provided on the reel surface facing this opening, the flexible hose is rotated by the reel rotating around a horizontal rotation axis. For winding and unwinding, it can be easily wound and unwound from above the support member, and this winding is also unnecessary on the side opposite to the side where the lateral rotation axis of the reel is cantilevered. The handle can be easily operated by operating the handle of the reel surface which is not opened through the reel opening which is substantially opposed to the reel surface on the side surface which is opened to the outside with the support member opened.

The heating means includes a heater, an outer cylinder fitted around the outer periphery of the heater with a cylindrical gap, and pressurized water supplied from one end to the other end between the heater and the outer cylinder. When it is composed of a partition that forms a heat exchange passage by partitioning into a spiral passage, a maze, a multi-passage, etc., the outer cylinder and the partition around the heater are thin and extremely long compared to the length of the heater. By forming a heat exchange passage, the supplied water can be instantaneously heated efficiently while passing at high speed by pressurization. Hot water exceeding 100 ° C can be obtained by a small-sized small electric heater. Therefore, it is suitable for sterilization cleaning at high temperature, and is easy to handle and use.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a cleaning apparatus according to an embodiment of the present invention will be described in detail with reference to the drawings together with an embodiment thereof, to provide an understanding of the present invention.

As described above, the cleaning apparatus of the present embodiment comprises a heating means 1 for heating water, a pump 2 for pressurizing and supplying water to the heating means 1 and sending out the hot water from the heating means 1. A hot water injection mechanism 5 is constituted by a flexible hose 4 ejected from the guiding nozzle 3, and the heating means 1 of the hot water injection mechanism 5, the pump 2, and the control unit 6 of the hot water injection mechanism 5 are arranged in a housing 7. It has a conventional structure housed in a housing. In the present embodiment, in particular, the minimum size that can accommodate the nozzle 3 in the housing 7 as shown in FIG.
As shown in (a) of FIG. 2, the telescopic structure has a maximum size that cannot be accommodated in the housing 7. The expansion / contraction structure is a multi-tube expansion / contraction system, in which the nut 8 is fixed in a predetermined expansion / contraction state by tightening, and the fixing can be released by loosening the nut 8 and can be adjusted to a required length at each time.

At the same time, the closed position shown by the solid line in FIG. 1, shown by the imaginary line in FIG. 2, and shown by the solid line in FIG. 8, which is substantially flush with the outer surface of the peripheral wall of the housing 7, for example, the front peripheral wall 7a. FIG. 1 shows a reel 11 for winding the flexible hose 4 around the support member 9 which is opened and closed between an open position shown by a virtual line in FIG. 8, FIG. 9
The flexible hose 4 is supported on the reel 11 as shown in FIG.
Together with the nozzle 3 contracted to the minimum size, as the support member 9 is opened and closed, they are put in and out of the housing 7.

As described above, when all of the heating means 1, the pump 2, and the flexible hose 4 including the nozzle 3, which constitute the hot water injection mechanism 5, are housed in the housing 7 together with the electric control unit 6.
The flexible hose 4 and the nozzle 3 that are easily contaminated are collectively placed outside in a non-use state, so that it is possible to prevent the dust or the like from adhering and the germs from adhering to propagate. Also,
The flexible hose 4 is wound around the reel 11 on the support member 9 which is opened to the predetermined position with respect to the housing 7 and is housed as shown by the imaginary line in FIG. The flexible hose 4 can be pulled out and wound up simply by setting the open position to the open position, and the handling is the same as that in the conventional case where the flexible hose 4 is put together outside the housing 7 and is easy to use.

At the same time, the flexible hose 4 wound around the drawn reel 11 sprays hot water sprayed from its own nozzle 3 and sterilizes and cleans the inside of the support member 9 and the housing 7. By closing, the part that has been sterilized and washed, such as the flexible hose 4, can be immediately accommodated in the housing 7 without touching the part, so that sanitary properties are improved and the usability is good.

Further, when the support member 9 is closed, it becomes substantially flush with the peripheral wall 7a of the housing 7, so that there is no detail between the support member 9 and the housing 7. Is housed in the housing 7, the outer surface of the housing 7 is simplified, and there is no blind spot when sterilized by ultraviolet irradiation. The hygiene is improved, and the problem that the flexible hose 4 is deteriorated by the irradiation of ultraviolet rays is also solved.

Further, since the nozzle 3 has a telescopic structure and is smaller than the housing 7 and has a minimum size that can be accommodated therein, it also has a maximum size larger than the housing 7, so that the hand holding the nozzle 3 The length can be set to a sufficient length exceeding the size of the housing 7 without affecting the maximum length from the housing 3 to the tip of the nozzle 3 so as to facilitate the work. According to one embodiment, the dimensions of the housing are W500 mm, D650 mm, H820 mm,
The nozzle 3 has a three-stage expansion and contraction structure and can expand and contract in a length range of 415 to 855 mm, and has a tip tube 3b having a nozzle head 3a.
A flexible hose 4 in which a flexible heat-insulating cylinder 12 is fitted to the outer circumference through the base cylinder 3d is provided on the inner circumference of the intermediate cylinder 3c between the base cylinder 3d on the connection side with the flexible hose 4. It is inserted and connected to the rear end of the tip tube 3b. Therefore, even if the intermediate cylinder 3c and the base cylinder 3d of the nozzle 3 are held by hand, the double insulation by the heat insulation cylinder 12 and the flexible hose 4 makes the person feel hot even when hot water passes. Can be eliminated.

In addition to the above, in the present embodiment, as in the case of the support member 9, the solid line shown in FIG. 1 and the virtual line shown in FIG. The support member 21 which is opened and closed between a position and an open position shown by a virtual line in FIG. 1 drawn out of the peripheral wall 7a by a predetermined amount and shown by a solid line in FIG. 7, the operation unit 22 is supported as shown by a solid line in FIG.
The operation unit 22 is moved in and out of the housing with opening and closing of the supporting member 21 that is supported. As a result, the operation unit 22 is easy to use as well as the flexible hose 4 and the nozzle 3, and the operation buttons 44 and the display lamps 45 are arranged as shown by phantom lines in FIG. The problem of hygiene due to this is also solved similarly in the case of the nozzle 3, and the hygiene is further improved. In addition, deterioration of the operation buttons 44 and the like due to irradiation with ultraviolet rays can be avoided.

A support member 9 for supporting the reel 11
And the support member 21 that supports the operation unit 22 is different,
When cleaning the flexible hose 4 wound on the reel 11, it is difficult for the hot water to reach the operation unit 22 supported by another support member 21, and the electric control unit 6 around the operation unit 2
It is possible to prevent the hot water from adversely affecting various electric devices and facilities including the above.

Also, as shown in phantom lines in FIG. 1 and as shown in FIG.
The opening stroke is set smaller than that of the support member 11 supporting the first member 1 and the spring 2 shown in FIG.
It is energized by 3 and so on. Further, after the opening operation of the support member 9 supporting the reel 11 at the final stage, the support member 21 supporting the operation unit 22 is opened in conjunction with the operation so that the support members 9 and 21 are simultaneously opened. The interlocking means 24 shown in FIG. The interlocking means 24 is in contact with the support member 9 after the final stage of the opening operation to engage the pair of engagement pieces 25 to open the support member 21 against the spring 23.
a and 25b, but the specific configuration can be variously changed.

The difference in the opening strokes of the two support members 9 and 21 causes the operation portion 22 to be pulled out more than necessary and obstructs the surroundings, or to be inadvertently touched to cause erroneous operation or failure. This can be easily prevented. Moreover, even if the two support members 9 and 21 are provided and the opening strokes are different, the other support member 21 is delayed against the urging in conjunction with the opening of one of the support members 9. When the one support member 9 is closed and the other support member 21 is closed simultaneously with the urging force of the spring 23, the one support member 9 can be closed and then the one support member 9 can be closed. It is only necessary to open and close one of the support members 9, and it is easy to use. In addition, the structure of the interlocking means 24 for this purpose is simple, and does not particularly cause an increase in size or cost. An operation handle 41 for opening / closing is provided on the side of the support member 9 for opening / closing operation.

The support member 21 supports the operation part 22 so as to be substantially upward at a substantially upper end thereof as shown in FIG. It is naturally easy to reach and operate. As one embodiment, the control unit 6 is built in below the operation unit 22 so that it is located at a low position and is hardly affected by hot water.

The support members 9 and 21 can be opened and closed with respect to a lower edge 26a of the opening 26 shown in FIGS. 1, 7 and 8 which is fitted when the support member 9 is closed substantially flush with the peripheral wall 7a of the housing 7. 7 and 8, each of which has a fan-shaped box shape centered on the connection portion by the hinge 27 as shown in FIGS.
As a result, it is possible to reduce the volume toward the lower hinge connection portion while securing the volume required for supporting the reel 11 and the operation portion 22 at the upper portion. Without reducing the installation space for the heating means 1, the pump 2, and the related devices such as the drive motor 31, the safety device 32, and the control device 33 as shown in FIG. The opening / closing stroke for sufficiently pulling out or housing the reel 11 and the operation unit 22 can be satisfied, and the housing 7 can be prevented from being enlarged. Further, since the support members 9 and 21 are box-shaped, the reel 11
In the case of supporting the operation part 22, the flexible state of the wound hose 4 and the like is preferably washed with hot water to prevent hot water from being scattered outside the necessary area. It is possible to prevent hot water or inappropriate external force from being applied to the electrical components such as the control unit 6 around the motor 22.

In addition, the supporting member 9 has a box shape which is open upward, and if the drain port 35 is provided at the lower part, the flexible hose 4 wound around the reel 11 is provided.
Since the hot water after washing can be collected at a predetermined place with the drain port 35 and discharged for processing, the safety of the apparatus and the worker in handling the hot water can be improved.

The supporting member 9 has the shape of a box that is open upward, and also has a side wall 9a that is open to the outside at the open position as shown by a virtual line in FIG.
8 and 9, a reel opening 37 is formed by cutting at least a region substantially opposite to the reel surface 11a of the reel 11 cantilevered by the support frame 39 on the opposite side wall 9b. An operation handle 38 is provided on the reel surface 11a facing the opening. As a result, when the reel 11 rotates around the horizontal rotation shaft 36, the flexible hose 4 can be wound or unwound from above the support member 9 without difficulty to wind and unwind the flexible hose 4. The handle 38 of the reel surface 11a on the side opposite to the side on which the lateral rotation shaft 36 of the reel 11 is cantilevered is attached to the side surface 9a which is opened to the outside with the support member 9 opened. It can be easily operated by operating through the reel operation port 37 located in a range substantially opposed to the reel surface 11a.

The heating means 1 includes a heater 51 shown in FIG. 4, an outer cylinder 52 shown in FIG. 6 fitted around the outer periphery of the heater 51 with a cylindrical gap, a heater 51 and an outer cylinder 52.
And a partition 54 for partitioning into a spiral passage, a maze, a multi-passage, and the like to form a heat exchange passage 53 as shown in FIG. 5 through which pressurized water supplied from one end to the other end passes. Thereby, a thin and extremely long heat exchange passage is formed around the heater 51 by the outer cylinder 52 and the partition portion 54, and the length of the heat exchange passage is extremely long as compared with the length of the heater 51. It is possible to heat instantly efficiently while moving, and to obtain hot water exceeding 100 ° C. under pressure by the small electric heater 51 of low capacity, which is suitable for high temperature sterilization cleaning, Easy to handle and use. It is simple and preferable to use a coil as shown in FIG. 5 for the partition part 54, but this can also be integrally formed on the outer surface of the heater 51 or the inner surface of the outer cylinder 52 by turning using a lathe. Further, those which are embedded in spiral grooves formed on those surfaces may be used. In this case, the heat exchange passage 53 in the form of a maze can be easily formed. As one embodiment, as shown in FIG. 3, the heating means 1 having the above structure is provided in two stages, upper and lower, so that water is passed in series. However, the present invention is not limited to this.
