FIG. 1 is a side view showing a high pressure washer 100 according to Embodiment 1 of the present invention. FIG. 2 is a side view showing the cleaning posture of the high-pressure washer 100 according to the first embodiment of the present invention. FIG. 3 is a diagram showing an example of a usage state of the high-pressure washer 100 according to the first embodiment of the present invention. In FIGS. 1 and 2, as shown in the coordinates, the left direction is the front side, the right direction is the rear side, the upper direction is the upper side, and the lower direction is the lower side.

As shown in FIG. 1, the high pressure washer 100 includes a main body 110, a nozzle 120 extending from the main body 110 in a first direction a, and a handle 130 formed on the upper side of the main body 110.

As shown in FIG. 1, the main body 110 includes, for example, a pump 111 and a motor 112. The outer shape of the main body 110 is, for example, bent so as to extend along the rear from the side where the nozzle 120 is provided and then extend diagonally downward toward the rear. The cross-sectional shape of the main body 110 when cut in a direction perpendicular to the direction in which it extends is, for example, approximately circular. The pump 111 pressurizes the cleaning liquid (water, etc.). The pump 111 is housed near the front portion 110a of the main body 110 (on the nozzle 120 side). Pump 111 is connected to nozzle 120. Pump 111 is connected to a motor 112 that drives pump 111. The motor 112 is housed in the center of the main body 110. Main body 110 further includes a battery 113. A battery 113 is attached to the rear portion 110b of the main body 110, more specifically, to the rear end surface 110c. The battery 113 supplies electricity as a driving source for the high pressure washer 100. The battery 113 is electrically connected to the motor 112 and the like by being inserted into an opening formed in the rear end surface 110c of the main body 110. The rear end surface 110c of the main body 110 is provided with a connection port 114 for connecting a hose (not shown) that supplies cleaning liquid from the outside. Pump 111 and connection port 114 are connected via hose 115.

The nozzle 120 is for spraying cleaning liquid pressurized by the pump 111. Nozzle 120 is connected to pump 111. Further, the nozzle 120 is provided so as to extend in the first direction a, in this embodiment, from the main body 110 to the front side. In other words, the first direction a is the direction in which the barrel of the nozzle 120 extends from the main body 110. At the tip of the nozzle 120, various attachments 121 can be attached that can change the direction and speed of ejection.

The handle 130 is attached to the upper side of the main body 110. As an example, the handle 130 refers to a portion of the opening 131 formed above the main body 110 that is away from the peripheral surface of the main body 110, that is, an upper edge portion of the opening 131. Handle 130 is configured to include a grip 132 that is grasped by a user when performing a cleaning operation. The grip 132 is formed to extend in the second direction b, which is the direction from the main body 110 toward the nozzle 120 side. That is, the second direction b is a direction toward the side of the main body 110 to which the nozzle 120 is attached, that is, a direction toward the front side. In this embodiment, the second direction b and the first direction a are parallel. Furthermore, the grip 132 refers to a portion of the handle 130 that extends forward in parallel to the first direction a. Note that the direction in which the handle 130 (grip 132) extends and the direction in which the nozzle 120 extends coincide with each other when viewed from above.

The cleaning posture of the high-pressure washer 100 will be explained using FIG. 2. The cleaning posture refers to a posture in which the extending direction (second direction b) of the grip 132 is horizontal and the main body 110 is located vertically below the grip 132. Since the extending direction (second direction b) of the grip 132 is horizontal and the main body 110 is located vertically below the grip 132, the main body 110 can be suspended when the grip 132 is gripped from above.

Moreover, when the high-pressure washer 100 takes the above-mentioned cleaning posture, the first direction a is configured to be parallel to the second direction b. That is, the high-pressure washer 100 is configured such that the extending direction of the nozzle 120 faces the horizontal direction (forward) when the grip 132 is held from above. Thereby, the cleaning liquid can be sprayed horizontally from the nozzle. In particular, it can be sprayed in a direction slightly downward from the horizontal direction. In the above configuration, the high-pressure washer 100 has the main body 110 hanging in the cleaning posture, so the high-pressure washer 100 can be handled with the elbows extended without bending the elbows. Therefore, when the high-pressure washer 100 is in the cleaning posture, the weight of the high-pressure washer 100 is distributed not only over the forearm but also over the entire arm and shoulder, making it easy to clean for a long time. Furthermore, since the nozzle 120 faces forward in the cleaning posture, there is no need to support the nozzle 120 with the other hand, and the high-pressure washer 100 can be handled with one hand. Furthermore, by turning the wrist while gripping the grip 132 from above, the high-pressure washer 100 (nozzle 120) can be turned vertically and horizontally. Therefore, it is possible to wash the body without directing the body toward the object to be washed, and it is easy to handle it.

Note that in this embodiment. Although the first direction a and the second direction b are parallel, for example, as shown in FIGS. 4 to 7, an angle θ may be set between the first direction a and the second direction b. good. The angle θ between the first direction a and the second direction b is configured to be less than 45 degrees, and more preferably less than 30 degrees. For example, as shown in Figure 4, if the angle θ between the first direction a and the second direction b is less than 30 degrees, the height from approximately the waist to below the knees when in the washing posture. It is possible to easily spray (spray water) onto a certain location. Therefore, it is suitable for cleaning bathroom B, for example (see FIG. 3).

As shown in FIG. 2, the high-pressure washer 100 is configured such that the center of gravity G of the high-pressure washer 100 is located vertically below the grip 132 in the cleaning posture. The center of gravity G of the high pressure washer 100 refers to the center of gravity G that includes the main body 110, the nozzle 120, and the grip 132 (handle 130). It is desirable that the center of gravity G of the high-pressure washer 100 is located below the center of the grip 132. As a result, when the grip 132 is gripped from above and the main body 110 is hung, the direction in which the grip 132 extends (second direction b) is horizontal, so that the user can comfortably assume the cleaning posture.

The main body 110 includes a pump 111, a motor 112, and a battery 113 such that the center of gravity G of the high-pressure washer 100 is located vertically below the grip 132 in the cleaning posture. More specifically, for example, the pump 111 and the motor 112 are arranged on the front 110a side of the main body 110 (on the nozzle 120 side), and the battery 113 is arranged on the rear 110b side of the main body 110 (on the side opposite to the nozzle 120 side). Thus, the center of gravity G of the high-pressure washer 100 is positioned vertically below the grip 132, that is, at the center of the main body 110 in the front-rear direction.

In the above configuration, by arranging the pump 111 and the motor 112 at one end of the main body 110 in the front-rear direction, the internal space of the main body 110 can be used efficiently. The high pressure washer 100 further includes a battery 113, and by arranging the battery 113 at the other end of the main body 110 in the front-rear direction, the battery 113 is placed vertically below the grip 132, that is, in the center of the main body 110 in the front-rear direction. It becomes possible to adjust the position of the center of gravity G of the high pressure washer 100. As described above, the high-pressure washer 100 separates and arranges the heavy objects (pump 111, motor 112, battery 113) at one end and the other end in the front-rear direction of the main body 110, so that the desired position (grip 132) The center of gravity G of the high-pressure washer 100 is located vertically below.

As shown in FIGS. 1 and 2, the grip 132 is provided with a switch 140 as an operating tool for driving the motor 112. The switch 140 is, for example, a push type. The switch 140 is configured to turn the motor 112 on and off when pressed. Specifically, the motor 112 is driven only while the switch 140 is pressed. Thereby, the cleaning liquid pressurized by the pump 111 can be sprayed from the nozzle 120 only while the switch 140 is pressed. Note that when the motor 112 is driven, the number of rotations of the motor 112 is set to a predetermined number of rotations.

A switch 140 is provided on the grip 132. More specifically, it is provided so as to protrude toward the main body 110 from the surface (inner peripheral surface) of the grip 132 that faces the main body 110 . This allows the user to press the switch 140 with his or her fingers when gripping the grip 132 from above, improving operability.

Further, the switch 140 is provided near the end of the grip 132 on the nozzle 120 side. The vicinity of the end of the grip 132 on the nozzle 120 side refers to the vicinity of the front end of the grip 132, and more specifically refers to a position that can be touched by the index finger when gripping the grip 132. This allows the switch 140 to be pressed with the index finger, improving operability.

Note that although the switch 140 is provided as an operating tool for driving the motor 112, the switch 140 is not limited to this, and may be a sliding type that can be switched between two positions, for example. Further, the switch 140 is configured to drive the motor 112 only while being pressed, but the present invention is not limited to this. When the switch 140 is pressed, the motor 112 is driven, and when the switch 140 is pressed again, The configuration may be such that the drive of the motor 112 is stopped.

Although the water pressure when driving the motor 112 is constant, the present invention is not limited to this, and an operating tool for changing the rotation speed of the motor 112 may be provided. In this case, the rotation speed of the motor 112 may be configured to have multiple levels, or the rotation speed of the motor 112 may be configured to be adjustable to an arbitrary rotation speed using a dial or the like.

As shown in FIGS. 1 and 2, the handle 130 is provided with a switch 150 as an operating tool for releasing the locked state of the switch 140. The switch 150 is, for example, a push type. When the switch 150 is pressed, the locked state of the switch 140 is released for a certain period of time or from when the switch 140 is turned on until it is turned off. The locked state of the switch 140 refers to a state in which the switch 140 cannot be pushed in, that is, a state in which the motor 112 is not driven. This makes it possible to prevent unintended jetting (spraying caused by inadvertently pressing the switch 140 when gripping the grip 132, etc.).

The switch 150 is provided on the handle 130 at a position other than the grip 132. The switch 150 is provided, for example, on the front end side of the handle 130. This allows the switch 150 to be pressed with the thumb or the like while gripping the grip 132, improving operability.

Note that although the switch 150 is provided as an operating tool for releasing the locked state of the switch 140, the switch 150 is not limited thereto, and may be a sliding type that can be switched between two positions, for example.

The connection port 114 is provided on the rear end surface 110c of the main body 110. Since the connection port 114 is formed to face diagonally downward at the rear, a hose connected to the connection port 114 and supplying cleaning liquid from the outside is guided diagonally downward at the rear. Therefore, in the cleaning posture, the user's feet do not get tangled, and handling is not complicated. Further, even if the hose is wet with water or the like, it is possible to reduce the risk of clothes etc. getting wet.
