Abstract

(57) [Summary] [Purpose] To provide a water sub tank for a vehicle in which the water level in the tank is easily visible. [Structure] Connecting the connecting pipes 7 and 8 to the upper and lower two places of the water sub tank 1 and providing transparent pipes 10 communicating with them.
The upper and lower ends of the transparent tube 10 were detachably closed with thumb screw cocks 11 and 12, and a white seal 16 was attached to the side surface of the water sub tank 1 on the transparent tube 10 side. [Effect] When the transparent tube is viewed from an angle such that the white sticker is in the background, the color of the cooling water is conspicuous, so that the liquid level can be visually recognized even if there is some scale.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle water sub tank provided in a vehicle such as an automobile.

[0002]

[Prior art]

 Conventionally, water sub tanks of this type include, for example, "Water tank" disclosed in Japanese Utility Model Laid-Open No. 63-141827 and "Vehicle water reserve tank" disclosed in Japanese Utility Model Laid-Open No. 1-124331. .

As shown in FIGS. 3 and 4, the former is provided with a water level pipe 52 in a water tank main body 51 which contains cooling water containing an antifreeze liquid having a varying concentration, and the water level pipe 52 is provided with an optional antifreeze liquid. One or more floats 53 having the same specific gravity as the cooling water corresponding to the concentration are arranged.

In the latter case, as shown in FIGS. 5 and 6, a lid 62 is provided above the see-through portion 61 and the rod 63 is provided with the see-through portion in order to prevent the liquid level from being invisible due to water stains or the like. 61 A bristle brush body 64 that slidably contacts the inner surface is provided, and the lower edge of the brush body 64 is located below the low level position.

[0005]

[Problems to be solved by the device]

 However, according to the former, due to long-term use, deterioration of cooling water, and the like, water stains adhere to the inner surface of the water level tube 52 and the surface becomes cloudy, making it difficult to check the water level by the float 53.

On the other hand, according to the latter, the adhered water stains and the like are removed by the brush body 64, but the location of the brush body 64 is limited by the liquid level, and the see-through portion 61 is integrated with the tank body 65. Therefore, the visible range was extremely limited.

[0007]

[Means for Solving the Problems]

 The present invention has been made in view of the above points, and solves the above problems by providing a vehicle water subtank having a structure that is easily visible even if there is scale, and that is easy to maintain and clean. Is.

Therefore, in this invention, connecting pipes are connected to the upper and lower portions of the water sub-tank, transparent tubular water level meters communicating with these connecting pipes are provided, and the upper and lower ends of the water level gauge can be freely attached and detached with a screw cock. The structure is characterized in that a white part is formed on the side surface of the water sub tank on the water level gauge side.

In order to form the white portion, for example, a white sticker may be attached in addition to the white coating.

[0010]

[Action]

 The water gauge is easy to see because it is installed outside the water sub tank.

Moreover, since the white portion is formed on the side surface of the water sub tank on the side of the water level gauge, unless the liquid is white, the color of the cooling water will stand out if the water level gauge is viewed from an angle such that the white area is in the background. , The liquid level becomes easier to see. Therefore, even if a small amount of scale adheres to the inside of the water level gauge, the liquid level can be confirmed.

Further, by removing the upper and lower screw cocks, it is possible to easily clean the inside of the water level gauge with a toothbrush or a brush brush for a test tube.

[0013]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of the present embodiment, in which 1 is a water sub tank made of an invisible material for storing cooling water therein, A supply pipe 2 for supplying cooling water to the engine (not shown) and a recirculation pipe 3 for recirculating from the engine are connected to the upper side of the one side. Further, a pipe 4 for sending cooling water to a radiator (not shown) for cooling is connected to the bottom surface of the water sub tank 1, and a water injection port 6 sealed with an openable lid 5 is provided on the upper surface. It is provided.

On the other side of the water sub-tank 1, connecting pipes 7 and 8 communicating with the inside of the water sub-tank 1 are connected by one-touch clamps 9 and 9 at upper and lower portions, and the connecting pipes 7 and 8 are made of acrylic resin. The upper and lower sides of the transparent tube 10 are connected by one-touch clamps 9, 9 and communicate with each other. This transparent tube 10 constitutes a water level gauge.

The transparent tube 10 has a tube shape with open upper and lower ends, and thumb screw cocks 11 and 12 are watertightly screwed to the upper and lower openings thereof, respectively. Further, rubber caps 13 and 13 are fitted on the upper and lower opening edges of the transparent tube 10 from above the thumbscrew cocks 11 and 12, respectively. Further, on the outer circumference of the transparent pipe 10, an upper limit display 14 and a lower limit display 15 for indicating an appropriate storage range of the cooling water of the water sub tank 1 are provided, respectively.

A white seal 16 is attached between the connecting pipes 7 and 8 on the surface of the water sub tank 1 on the transparent pipe 10 side.

The present embodiment has the above-described configuration, and since the transparent pipe 10 serving as a water level gauge is provided separately from the water sub tank 1, the water level of the cooling water in the water sub tank 1 can be adjusted from any direction. Can be seen. Moreover, when viewed from an angle such that the white sticker 16 is in the background, the color of the cooling water becomes more visible, making it easier to see, and even if some water stains adhere to the inside of the transparent tube 10, the liquid level can be confirmed. It is possible.

By the way, as shown in FIG. 2, in a cab-over type transportation vehicle 17, for example, a water sub-tank of this type is usually installed in the rear of the operator's cab, but the transparent pipe 10 is positioned diagonally in the rear. If the sub-tank 1 is installed, the white seal 15 is located on the background of the transparent pipe 10 and the water level of the cooling water can be seen very clearly even from the side location A and the rear location B as shown in FIG. Is. In this case, if the lengths of the connecting pipes 7 and 8 are shortened and the transparent pipe 10 is brought close to the side surface of the water sub tank 1, the area in which the white seal 15 comes to the background is further expanded. Of course, since the transparent pipe 10 is independent of the water sub tank 1, the water level of the cooling water can be confirmed from any direction.

If a large amount of scale or the like adheres to the inner wall of the transparent tube 10 and the surface becomes cloudy and becomes difficult to see, remove either the upper or lower rubber cap 13 and remove the thumb screw cock 11 or 12. Thus, the inner wall of the transparent tube 10 can be easily cleaned by the toothbrush 18 and the test tube brush 19 shown in FIG. Therefore, maintenance is very easy.

[0020]

[Effect of device]

 According to this invention, since the water level gauge is provided outside the water sub tank, the range in which the liquid level of the water level gauge can be visually recognized is wide.

Moreover, since the white portion is formed on the side surface of the water sub-tank on the water level side, unless the liquid is white, the color of the cooling water stands out if the water level gauge is viewed from an angle such that the white area is in the background. , The liquid level becomes easier to see. Therefore, even if a small amount of scale adheres to the inside of the water level gauge, the liquid level can be confirmed.

Further, by removing the upper and lower screw cocks, the inside of the water level gauge can be easily cleaned with a toothbrush, a brush brush for a test tube, etc., and maintenance is very easy.
