Description

  The present invention relates to a high pressure washer, and more particularly, to a high pressure washer having a hose reel.

  2. Description of the Related Art Conventionally, there is known a high pressure washer that can remove dirt stuck to a floor, a wall, or concrete by spraying water with a strong pressure. A general high-pressure washing machine has an electric motor as a driving source and a pump mechanism that generates high-pressure water by driving the supplied water by pressurizing the supplied water, and is supplied from the water inlet. The water to be discharged is pressurized by a pump mechanism driven by an electric motor to become high-pressure water, and the high-pressure water is discharged through a water discharge port and a water discharge device (nozzle gun or the like).

  In such a conventional high-pressure washing machine, it is generally performed by connecting a water outlet and a water discharge device (nozzle gun or the like) with a hose. In addition, this type of hose has been used with a hose reel installed in consideration of handling and storage convenience during use.

  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments for carrying out the present invention will be described with reference to the drawings. The following embodiments do not limit the invention according to each claim, and all combinations of features described in the embodiments are not necessarily essential to the solution means of the invention. .

  FIG. 1 is an external perspective view showing the overall configuration of the high pressure washer according to this embodiment, and FIG. 2 is an external front view of the high pressure washer according to this embodiment. Moreover, FIG. 3 is a figure which shows the state which removed the front side of the housing | casing which comprises the outline of the high pressure washing machine which concerns on this embodiment, and FIG. 4 shows the internal structure of the high pressure washing machine which concerns on this embodiment. It is a longitudinal cross-sectional front view for demonstrating.

  As shown in FIG. 3, the high-pressure washer 10 according to the present embodiment is driven by the motor unit 11 in which the electric motor 12 serving as a driving source is housed and the electric motor 12, thereby supplying water to be supplied. A pump mechanism 21 for generating high-pressure water by pressurization and a hose reel 31 for winding a hose 30 connected to the pump mechanism 21 are provided.

  As shown in FIG. 4, an electric motor 12 that is rotationally driven by external power supplied from a power source (not shown) is accommodated in the motor unit 11. The electric motor 12 includes a rotor 13 as a field magnetic flux generation source and a stator 14 for generating a rotating magnetic field for rotating the rotor 13. The rotor 13 includes a motor shaft 13a, and a swash plate 13b is attached to the tip of the motor shaft 13a. The electric motor 12 exhibits a function as a drive source by transmitting the rotational movement of the swash plate 13b to a pump mechanism 21 described later. On the other hand, the stator 14 is fixedly installed in the motor unit 11.

  Further, in the motor unit 11 according to the present embodiment, a cavity 15 for conducting cooling water for cooling the electric motor 12 is formed so as to surround the outer periphery of the electric motor 12. The cavity 15 is in contact with the stator 14 and is disposed so as to surround the stator 14 and a metal inner casing 15a, and an outer side disposed so as to surround the outer periphery of the inner casing 15a. The casing 15b is formed so as to have a substantially cylindrical shape.

  The inner casing 15a is made of a metal having high thermal conductivity such as an aluminum alloy, for example, in order to efficiently transfer the heat transmitted from the stator 14 to the cooling water in the cavity 15. Further, an O-ring 15c is installed between the inner casing 15a and the outer casing 15b in order to surely prevent leakage of cooling water from the cavity 15. In the present embodiment, two O-rings 15c are installed.

  As described above, the motor unit 11 according to the present embodiment is configured to include the water-cooled cooling mechanism, and thus does not need to include a cooling fan. That is, since it is not necessary to provide the housing 51 with an opening for taking in cooling air, the noise leaking to the outside is extremely reduced.

  On the other hand, the pump mechanism 21 is a member that is connected to the motor unit 11 via the swash plate 13b so that power can be transmitted. In the pump mechanism 21 according to the present embodiment, three pistons 22 that reciprocate in a substantially horizontal direction are installed in contact with a thrust bearing 13c embedded in an inclined surface on the shaft end surface side of the swash plate 13b. Yes. The three pistons 22 are provided with springs 22a, and an elastic force is always applied to the thrust bearing 13c side by the action of the springs 22a (that is, the right direction in FIG. 4), and the springs 22a. The piston 22 is configured to move to the left when a lateral force (left direction in FIG. 4) against the elastic force is applied. That is, each of the three pistons 22 is configured to perform reciprocating piston movement in a substantially horizontal direction (left-right direction).

  The pump inner region 23 where the thrust bearing 13c embedded in the swash plate 13b and the three pistons 22 are in contact with each other is filled with lubricating oil, and a good contact state between the thrust bearing 13c and the three pistons 22 is obtained. It is configured to be realized. Therefore, when the electric motor 12 is driven and the motor shaft 13a is rotationally driven, the swash plate 13b is rotationally driven by this rotational driving force. When the swash plate 13b is rotationally driven, the shaft of the swash plate 13b is driven. Since the thrust bearing 13c is rotated by the action of the inclined surface formed on the end face side, the three pistons 22 are sequentially pushed in the anti-swash plate direction (the left side in FIG. 4) by the thrust bearing 13c. At the same time, the pushing in this direction is released, and the three pistons 22 perform reciprocating piston movement in order.

  The water sent via the water inlet 16 is guided to the tip of the three pistons 22. The water guided to the left position of the installation location of the three pistons 22 is pressurized by the action of the reciprocating piston movement by the pistons 22 to generate high-pressure water.

  The high-pressure water generated by being pressurized by the pump mechanism 21 is guided to the hose 30 connected to the pump mechanism 21 and used for high-pressure washing work to the outside. The high pressure washer 10 according to this embodiment includes a hose reel 31 for winding the hose 30, and the length of the hose 30 can be adjusted according to the working environment. The hose reel 31 is provided with a handle 32 so that the reel can be easily rotated. The handle 32 can be taken out and stored in a storage recess 54 formed on the right side surface of the casing 51, so that the operability of the high-pressure washing machine 10 is improved and the apparatus is made compact.

  The motor unit 11, the pump mechanism 21, and the hose reel 31 described above are housed and installed in a housing 51 that constitutes the outline of the high pressure washer 10. The housing 51 is configured by combining the front and rear half members constituting the front side and the rear side. Further, a grip 52 is formed at the upper center position of the casing 51, and a pair of left and right tires 53 are formed at the lower rear position. Since the high pressure washer 10 according to the present embodiment is configured so that the center of gravity is slightly forward when in the self-standing state illustrated in FIGS. 1 to 4, the pair of left and right tires 53 do not function. Therefore, it is possible to maintain a stable and independent state. In addition, when the user moves, the user holds the grip portion 52 and tilts backward so that the pair of left and right tires 53 positioned at the lower rear of the housing 51 can be rotated, so the grip portion 52 is tilted rearward. However, the high-pressure washing machine 10 can be easily moved by pulling backward.

  In the high pressure washer 10 according to the present embodiment, when the high pressure washer 10 is in a self-supporting state, the motor unit 11 having the electric motor 12 and the pump mechanism 21 are arranged side by side at a position below the housing 51. The hose reel 31 is disposed above the housing 51. That is, the motor unit 11 and the pump mechanism 21 which are heavy objects are disposed at a position below the casing 51, and the hose reel 31 having a relatively smaller weight than these is disposed at a position above the casing 51. Therefore, the high pressure washer 10 according to the present embodiment has a very good weight balance, and a stable self-supporting state can be realized. Moreover, since the hose reel 31 having the handle 32 that receives an operation when the hose 30 is taken in and out from the user is disposed on the upper side of the housing 51, high operability is realized.

  In addition, about the motor unit 11 and the pump mechanism 21 of this embodiment, in order to maintain the stable installation state in the housing | casing 51, with respect to the housing | casing 51 opposing surface of the motor unit 11 and the pump mechanism 21, respectively. A support portion 55 connected to the inner surface side of the casing 51 is formed. As shown in FIG. 3, the support portion 55 of the present embodiment is formed as a cylindrical convex portion, and is a recess (non-removable) for storing the support portion 55 provided on the inner surface side of the housing 51. The motor unit 11 and the pump mechanism 21 in the housing 51 are stably installed by being fitted with each other. In addition, about the shape of this support part 55 and the recessed part by the side of the housing | casing 51 for accommodating the support part 55, all shapes are employable. Further, for the support portion 55, it is preferable to employ an elastic member in order to obtain effects such as vibration isolation and sound insulation.

  The basic configuration of the high pressure washer 10 according to the present embodiment has been described above. Next, the detailed configuration of the hose reel 31 included in the high-pressure washer 10 according to the present embodiment will be described with reference to FIGS.

  Here, FIG. 5 is an exploded perspective view of the hose reel 31 according to the present embodiment. 6 and 7 are views showing the hose reel 31 when the handle 32 is in the storage position. In particular, FIG. 6 is an external front view, and FIG. 7 is a cross-sectional view taken along the line VII-VII in FIG. Show. Further, FIG. 8 is a longitudinal sectional view of a main part for explaining the configuration of the clutch mechanism according to the present embodiment, and particularly shows a state where the handle is in the storage position. On the other hand, FIGS. 9 and 10 are views showing the hose reel 31 when the handle 32 is in the operation position, and in particular, FIG. 9 is an external front view, and FIG. 10 is an XX cross-sectional view in FIG. Show. FIG. 11 is a longitudinal sectional view of a main part for explaining the configuration of the clutch mechanism according to the present embodiment, and particularly shows a state where the handle is in the operation position.

  The hose reel 31 according to the present embodiment suitably rotates the rotating drum 33 around which the hose 30 is wound, the handle 32 that exerts a rotational force on the rotating drum 33, and the hose 30 to be wound around the rotating drum 33. The traverse mechanism 34 is configured.

  The rotating drum 33 and the handle 32 are connected via a clutch mechanism 61 described later. The handle 32 is provided so that it can take two positions, that is, an operation position as shown in FIGS. 9 to 11 and a storage position as shown in FIGS. 6 to 8. When the handle 32 is in the operating position by the cooperative action of the handle 32 and the clutch mechanism 61, the handle 32 and the rotating drum 33 are connected, so that the rotational force from the handle 32 is applied to the rotating drum 33. It is configured to allow transmission. On the other hand, when the handle 32 is in the storage position, the connection between the handle 32 and the rotary drum 33 is released, so that the rotational force from the handle 32 cannot be transmitted to the rotary drum 33.

  Here, a specific configuration for realizing the cooperative operation of the handle 32 and the clutch mechanism 61 as described above will be described with reference to FIGS. 5, 8, and 11.

  The clutch mechanism 61 according to the present embodiment includes a first gear 62 fixedly installed on the rotary drum 33. The first gear 62 is a member in which a spline groove 62a is formed on the inner peripheral surface and a gear gear 62b is formed on the outer peripheral surface.

  A handle connection shaft 63 is provided so as to penetrate the inner peripheral surface of the first gear 62. The handle connection shaft 63 is axially connected to the handle 32 so that the shaft end portion on the outer side (that is, the counter-rotating drum side) can tilt. This shaft connection is realized by the engagement of the tilt shaft 63b included in the handle connection shaft 63 and the tilt bearing 32b included in the handle 32.

Further, an engaging member 64 is installed at the shaft center portion of the handle connecting shaft 63. The handle connection shaft 63 and the engagement member 64 are spline-coupled at a position denoted by reference numeral S ₂ , and the engagement member 64 is movable with respect to the axial direction of the handle connection shaft 63, and the handle connection shaft 63. It is impossible to rotate around the axis. Further, a spline groove 64 a that meshes with the spline groove 62 a formed on the inner peripheral surface of the first gear 62 described above is formed on the outer peripheral surface of the engagement member 64. By the spline groove 62a and the spline groove 64a is engaged, it is splined as indicated by the letter S ₁ designates by which (the details will be described later) so as to realize in Fig.

Further, two coil springs (a first coil spring 65a and a second coil spring 65b) are installed on the inner side and the outer side in the axial direction of the engaging member 64 installed on the handle connection shaft 63. . The first coil spring 65a located on the outer side, a first retaining ring 65a ₁ provided on the shaft center portion of the handle connecting shaft 63, is installed between the wall surface of the inner peripheral surface of the first gear 62 Yes. Therefore, the elastic force of the first coil spring 65 a is exerted on the handle connection shaft 63.

On the other hand, the second coil spring 65 b located on the inner side is installed between the second retaining ring 65 b ₁ installed at the inner shaft end of the handle connection shaft 63 and the engaging member 64. . Accordingly, the elastic force of the second coil spring 65 b is exerted on the engaging member 64.

Therefore, as shown in FIG. 8, when the handle 32 is in the stowed position, the cam shape 32a formed at the base of the handle 32 does not act, so that the handle connecting shaft 63 is moved by the elastic force of the first coil spring 65a. It is pushed toward the inner side, that is, the side opposite to the handle, and moves toward the inner side. At this time, the engaging member 64 is pushed inward by the first retaining ring 65 a ₁ , so that the spline groove 62 a formed on the inner peripheral surface of the first gear 62 and the outer periphery of the engaging member 64. The spline grooves 64a formed on the surface are not engaged with each other. In other words, splined S ₁ described above, and thus be lifted. Therefore, when the handle 32 as shown in FIG. 8 is in the stowed position, the handle 32 and the rotating drum 33 are not connected to each other, and therefore, no rotational force is transferred between the handle 32 and the rotating drum 33. It becomes.

On the other hand, as shown in FIG. 11, when the handle 32 is moved to the operating position, the handle connecting shaft 63 resists the elastic force of the first coil spring 65a by the action of the cam shape 32a formed at the base of the handle 32. Therefore, it moves to the outer side, that is, the handle side. Then, since the first retaining ring 65a ₁ that has defined the position of the engaging member 64 also moves outward, the engaging member 64 is moved outward by the elastic force of the second coil spring 65b. Will move. Since the handle connecting shaft 63 moves outward, the second retaining ring 65b ₁ that regulates the position of the inner side of the second coil spring 65b also moves outward. The coil spring 65b can suitably exhibit the elastic force necessary to press the engaging member 64 outward.

Further, at this time, the spline groove 62a formed on the inner peripheral surface of the first gear 62 and the spline groove 64a formed on the outer peripheral surface of the engaging member 64 are in phase with each other. It will be possible to shift to a state in which 64a is engaged. In other words, so that the spline bond represented by the letter S ₁ designates 11 is achieved. Therefore, as shown in FIG. 11, when the handle 32 is in the operating position, the handle 32 and the rotating drum 33 are in a connected state, so that a rotational force can be transferred between the handle 32 and the rotating drum 33. Become.

  In this embodiment, the moment when the clutch mechanism 61 switches between the connected state and the released state of the handle 32 and the rotary drum 33 is performed when the handle 32 is at a position between the operation position and the storage position. Will be. The timing for switching between the connected state and the released state between the handle 32 and the rotary drum 33 is determined by the cam shape 32 a formed at the base of the handle 32. Therefore, how much the handle 32 is tilted when the connection state / release state of the handle 32 and the rotary drum 33 is switched can be arbitrarily set by changing the cam shape 32a.

  In addition, when the handle 32 according to the present embodiment is in the storage position, the handle 32 is stored in the storage recess 54 provided on the side surface of the housing 51. As described above, the handle 32 and the rotary drum 33 are stored. Switching between the connected state and the released state is performed when the handle 32 is at a position between the operation position and the storage position. Therefore, the release state of the handle 32 and the rotary drum 33 is switched before the handle 32 is stored in the storage recess 54. At this time, the handle 32 can be freely rotated irrespective of the rotary drum 33. Accordingly, in the present embodiment, the position of the handle 32 can be easily rotated and aligned with the position of the storage recess 54, and the storage operation of the handle 32 can be easily realized.

  In the present embodiment, at least a part of the outer peripheral side surface of the handle 32 stored in the storage recess 54, specifically, the side surface opposite to the grip portion at the tip of the handle 32 is the outer surface of the housing 51. It is configured so as to fit slightly inside. With this configuration, the high-pressure washer 10 according to the present embodiment has a compact device outer shape and a high design property that is excellent in appearance.

  Further, an intermediate gear gear 66 is engaged with a gear gear 62 b formed on the outer peripheral surface of the first gear 62, and this intermediate gear gear 66 is connected to the shaft end portion of the traverse shaft 34 a constituting the traverse mechanism 34. The installed traverse gear gear 34b is engaged. Therefore, when the handle 32 and the rotating drum 33 are connected by moving the handle 32 to the operating position, the rotational force from the handle 32 rotates the rotating drum 33 and the traverse shaft 34a at the same time. It becomes. And, on the shaft surface of the traverse shaft 34a, two spiral grooves of right and left threads are formed, and a hose guide 34c is engaged with the spiral groove. When the traverse shaft 34a rotates, the hose guide 34c engaged with any one of the spiral grooves moves in either direction, and the hose has moved to the other spiral groove at the shaft end of the traverse shaft 34a. The guide 34c moves in either one direction. Furthermore, since the hose guide 34c performs the same operation at both shaft ends of the traverse shaft 34a, the hose guide 34c according to the present embodiment reciprocates along the axial direction of the traverse shaft 34a. Become. Therefore, the hose 30 that is guided by the hose guide 34c and introduced into or discharged from the rotating drum 33 is wound or discharged in a regularly aligned state over the entire length of the rotating drum 33. Smooth storage operation and discharge operation are realized.

  As mentioned above, although preferred embodiment of this invention was described, the technical scope of this invention is not limited to the range as described in the said embodiment. Various modifications or improvements can be added to the embodiment.

  For example, in the above-described embodiment, at least a part of the outer peripheral side surface of the handle 32 stored in the storage recess 54, specifically, the side surface opposite to the grip portion at the tip of the handle 32 is It was configured to be slightly inside the outside surface. However, at least a part of the outer peripheral side surface of the handle 32 stored in the storage recess 54 may be configured to be substantially flush with the outer surface of the housing 51, for example. Even with such a configuration, it is possible to realize a high-pressure washing machine having a compact device outer shape and a high design that is excellent in appearance.

  It is apparent from the description of the scope of claims that embodiments with such changes or improvements can be included in the technical scope of the present invention.
