Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hot water dispenser attached to the tip of a hot water outlet pipe of a water heater.

[0002]

[Prior art]

 Conventionally, a hot water outlet equipped with a switching operation button for switching the discharge state of hot water between straight and shower is attached to the tip of the hot water outlet pipe of the water heater. The user can change the tapping direction and tapping position by moving the tapping tool in any direction, and the hot water discharge state can be switched by holding the tapping tool and pressing the switching operation button. You can The shape of the whole hot water supply tool is a cylindrical shape, and a seesaw operation type switching operation button is provided on the front surface thereof. FIG. 6 is a cross-sectional plan view showing the switching operation of the switching operation button. The switching operation button A is provided so as to rotate around the support shaft B, and when one side (for example, right side) of the operation surface C is pressed, a shower state is set, and when the other side (left side) is pressed. Switch to straight state.

[0003]

[Problems to be solved by the device]

 However, in such a water dispenser, there is a problem that the operability of the switching operation button is not so good. The reason will be described. First, as shown in FIG. 6, since the shape of the water discharge tool is a cylindrical body, the operation surface C on the side on which the operation button A is pressed protrudes from the water discharge tool body D (the protruding portion is finely hatched). ). In other words, while the shape of the hot water tool main body D is a cylindrical body, the operation surface C of the operation button A is almost flat, and thus the operation surface C protrudes. On the contrary, if the operation button A is provided at the back of the hot water supply device main body D so as to eliminate the protruding portion, a recessed portion will be formed this time. To improve operability, it is necessary to make the operation button A larger, but with this, the protruding portion becomes larger, which leads to a reduction in the image of the appearance and erroneous operation. For this reason, in the past, the operation button A could not be upsized, and the operability remained poor. Further, since the operation button A is small, a large operation force is required for switching. An object of the present invention is to solve the above-mentioned problems and to improve the operability of switching the discharge state of hot water.

[0004]

[Means for Solving the Problems]

 The hot water dispenser of the present invention, which solves the above-mentioned problems, is attached to the tip of the hot water outlet pipe of a hot water dispenser and has a switching operation button on the front surface for switching the discharge state of hot water between straight and shower. In the hot water dispenser, the gist is that the front surface provided with the switching operation button is a substantially rounded flat surface, and the side surfaces other than the front surface are substantially cylindrical surfaces having a curvature smaller than the roundness of the front surface.

[0005]

[Action]

 The water heater of the present invention having the above-described configuration has a rounded and substantially flat front surface, so that even if the operation surface of the switching operation button is flat, the operation surface is almost the same as the front surface of the water heater. Since it can be located on a plane, the switching operation button can be enlarged. As a result, the operability of the switching operation button is improved. Generally, when holding a bathing device, put your thumb on the front side and put your fingers and palm on the back side.However, since the curvature of the front side and the back side of the bathing tool are different, you do not have to look at the bathing tool. From this feeling, the hand is always guided naturally to the same position, and the thumb surely hits the switching operation button. This also improves operability.

[0006]

【Example】

 In order to further clarify the configuration and operation of the present invention described above, a preferred embodiment of the water heater of the present invention will be described below. FIG. 1 is a front view of a water heater of a water heater as an embodiment, FIG. 2 is a cross-sectional plan view thereof, and FIG. 3 is a vertical sectional front view thereof. The hot water supply tool of the present embodiment is composed of a switching main body 10 having a switching operation button 1 on the front surface, a shower tubular portion 30, and a cover tubular portion 50, which can be respectively attached and detached by engaging / disengaging portions 60, 61. It is provided in.

Although the overall shape of the hot water supply tool is a tubular shape, it is not a simple cylindrical shape as in the prior art, but a front surface provided with a switching operation button 1 as shown in FIG. 4 (cross-sectional plan view). Reference numeral 2 is an arc surface (rounded substantially flat surface) having a radius of curvature R1 considerably larger than the radius of curvature R2 of the back surface 3. Therefore, rounded corner portions 4 and 5 are formed on both sides of the front surface 2.

Next, each part will be described. However, since the switching mechanism is not a feature of the present application, it will be outlined. The details of the switching mechanism are described in Japanese Utility Model Publication No. 3-22371 filed earlier by the applicant of the present application.

The switching main body 10 is provided with a connecting tube 11 connected to the tip of the flexible hot water discharge pipe P in the central upper part, and a switching operation button 1 (hereinafter simply referred to as an operation button 1) is attached to the front surface 2. The button chamber 12 is recessed.

A cover cylinder 50 is provided on the upper part of the switching body 10. The cover tubular portion 50 has a holding portion 52 for a sealing material 51 (O-ring) that keeps the hot water outlet pipe P and the switching main body portion 10 watertight, and the hot water is discharged so as to cover the tip of the heat insulating flexible cover F of the hot water outlet pipe P. It is fitted into the pipe P.

A shower cylinder 30 is provided below the switching body 10. The shower tube portion 30 has a shower perforation nozzle 31 on the outer periphery of the lower end, a straight discharge port 32 at the center, and a straight valve hole 33 communicating with the straight discharge port 32 and a shower porous hole inside. A flow path forming body 35 having a shower valve hole 34 communicating with the nozzle 31 is attached via a sealing material 39 (O ring). A switching valve 36 that closes either the straight valve hole 33 or the shower valve hole 34 to switch the flow path is provided above the flow path forming member 35. The switching valve 36 is an obtuse V-shaped flat seesaw seal type plate-shaped switching valve rotatably supported by a support shaft 37, and one of the V-shaped surfaces is pressed by an elastic arm 15 which will be described later. The structure is such that the discharge state of is switched between straight and shower.

A button chamber 12 recessed in the front surface 2 of the switching main body 10 is provided with an operation button 1 which is provided so as to be pivotally displaceable in a forward-backward direction in a forward-backward direction by a predetermined angle with a support shaft 13 as a fulcrum. . The operation button 1 is a seesaw type push button whose operation surface 14 is formed in a substantially flat shape.

The support shaft 13 is provided with an elastic arm 15 that rotates left and right as the operation button 1 is rotated and displaced, and a tip end convex portion 16 of the elastic arm 15 slides while pressing on the switching valve 36. In addition, a mountain-shaped convex portion 38 is formed in the center of the V-shaped surface of the switching valve 36, and the tip convex portion 16 of the elastic arm 15 crosses over the mountain-shaped convex portion 38 to give the operation button 1 a snap feeling. . Therefore, when the user presses either the right or left operation surface 14 of the operation button 1, the operation button 1 pivots sharply to give the user a “click” feeling, and at the same time, the hot water discharge state is instantaneously displayed. Switches. In this example, when the left side of the operation surface 14 of the operation button 1 is pressed, the shower valve hole 34 is closed and in a straight state, and when the right side is pressed, the straight valve hole 33 is closed and in a shower state.

In the hot water dispenser configured as described above, the front surface 2 provided with the operation button 1 and the other side surface 3 have different curvatures, and the front surface 2 has a substantially flat cylindrical surface. Thus, the operation surface 14 on the pressed side of the operation button 1 is substantially flush with the front surface 2 of the hot water tool, and the protruding portion is small. Therefore, the operation button 1 itself can be enlarged in the lateral direction while suppressing the protruding portion, and the operability can be improved. In addition, the operating force is small. On the other hand, in the case of the conventional cylindrical hot water supply device shown in FIG. 6, when the operation button A is enlarged, the protruding portion becomes large, which leads to a reduction in the image of the appearance and erroneous operation. After all, the operation button A cannot be upsized and the operability cannot be improved.

Further, as shown in FIG. 5, when grasping the hot water tool, the thumb is placed on the front surface 2 side, and the other fingers and the palm are placed on the back surface 3 side. In the hot water tool of this embodiment, the front surface 2 and the back surface are arranged. Since the curvatures of 3 and 3 are different, the hand is always guided naturally to the same position with the feel of gripping without looking at the hot water outlet, and the thumb surely hits the operation button 1. In other words, one of the rounded corners 4 and 5 formed on both sides of the hot water tool is naturally grasped so as to be located between the thumb and the index finger (near the second joint of the thumb), and therefore the corner is Is caught between the thumb and forefinger, and a slight catch is obtained, and the grip position is fixed. Therefore, the thumb surely hits the operation surface 14 of the operation button 1 without slipping the hand. From this state, pressing the operation button 1 near the first joint of the thumb switches to the shower state, and pressing the operation button 1 with the tip of the thumb returns to the straight state (in the case of right hand operation). Therefore, the operability is very good.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and it is needless to say that the present invention can be implemented in various modes without departing from the gist of the present invention. is there.

[0017]

[Effect of device]

 As described in detail above, according to the hot water dispenser of the present invention, the front surface is rounded and substantially flat, so that the switching operation button can be made larger and the hot water dispenser can be gripped. Since the grip position can be known only by the feeling of touch, the thumb can be naturally placed on the operation button, resulting in excellent operability.
