Description

[Detailed explanation of the invention] (a) Technical field of the invention The invention relates to a reserve tank, and in particular to a reserve tank that stores cooling water that circulates through a radiator used in automobiles, etc., and supplies the stored cooling water to the radiator. It's about tanks.

(b) Background of the Technology In vehicles such as automobiles, a reserve tank is used to store cooling water circulating within a radiator and to supply the stored cooling water to the radiator. Rubber hoses are used as piping to connect the radiator and the reserve tank, but the longer the rubber hose becomes, the more costly it becomes, and the rubber hose must be fixed in the middle, so there is a demand for the rubber hose to be arranged as short as possible.

(c) Prior Art and Problems FIG. 1 shows the configuration of a conventional reserve tank described in Japanese Utility Model Application Publication No. 52-49233.

In Figure 1, reserve tank a is connected to hose b.
The reserve tank a is connected to the radiator c via a rubber hose b, and cooling water in the radiator c is supplied to the reserve tank a via a rubber hose b. On the other hand, radiator c
When the temperature of the cooling water in the reserve tank a decreases, the cooling water in the reserve tank a is supplied to the radiator c via the rubber hose b.

In this way, the reserve tank a shown in FIG.
Since the hose attachment port d is located at the bottom of the side of the tank a, the length of the rubber hose b must be longer than the straight line distance between the radiator c and the reserve tank a. When installing it, it is necessary to fix the middle of the rubber hose b to the vehicle body. Therefore, in the traditional configuration,
In order to arrange the rubber hose b, it is necessary to fix the rubber hose b in the middle, and the cost is increased.

Therefore, as shown in Fig. 2, if a reserve tank e is used in which the hose attachment port f is arranged at the top, the length of the rubber hose g connecting the radiator c and the reserve tank e is the same as the length of the rubber hose g that connects the radiator c and the reserve tank e. Since the length of the straight line distance from the rubber hose g is sufficient, the length of the rubber hose g can be shortened, and there is no need to fix the rubber hose g in the middle.

However, in the case of the reserve tank e shown in FIG. 2, if the rubber hose h is not provided in the reserve tank e, the cooling water stored in the reserve tank e will be transferred to the radiator c via the rubber hose g.
cannot be sent to. For this reason, even if the reserve tank e is used, the rubber hoses g and h are required as rubber hoses, so the length of the rubber hoses is approximately the same as that in FIG. 1. Moreover, in the case of the reserve tank e, there is a dead space D between the end of the rubber hose h and the bottom of the reserve tank e, so that all of the cooling water in the reserve tank e cannot be supplied to the radiator c.

(d) Purpose of the invention The present invention was made in view of the above-mentioned conventional problems, and its purpose is to shorten the length of the rubber hose that connects the radiator and the reserve tank, and to reduce the amount of water inside the reserve tank. To provide a reserve tank that can reliably feed cooling water to a radiator.

(E) Structure of the device In order to achieve the above object, the present invention has a hose attachment port near the top of the tank and a cooling water outlet at the bottom of the tank, and communicates the hose attachment port and the cooling water outlet. A communication pipe is integrally installed in the tank body.

(F) Embodiment of the invention A preferred embodiment of the invention will be described below based on FIGS. 3 to 5.

In the figure, a cooling water outlet 2 is provided at the bottom of a reserve tank 1 that stores cooling water.
Transfer the cooling water in reserve tank 1 to reserve tank 1
A communication pipe 3 leading to the upper side is provided. A hose attachment port 4 is provided at the end of the communication pipe 3. That is, the reserve tank 1 in this embodiment
has a hose attachment port 4 near the top of the tank, a cooling water outlet 2 at the bottom of the tank, and a hose attachment port 5.
A communication pipe 3 that communicates between the tank body and the cooling water outlet 2 is integrally formed with the tank body by blow molding.

For this reason, the reserve tank 1 in this embodiment
As shown in FIG. 6, a rubber hose 7 with a length approximately equal to the straight line distance between the radiator 5 and the reserve tank 1 is attached to the cooling water outlet 4, and the other end of the rubber hose 7 is connected to the cooling water outlet of the radiator 5. By attaching it to the water outlet 6, the cooling water in the radiator 5 can be stored in the reserve tank 1 through the rubber hose 7, and the cooling water stored in the reserve tank 1 can be stored in the reserve tank 1 through the rubber hose 7. It can be fed to the radiator 5. Moreover, since the reserve tank 1 in this embodiment is provided with the cooling water outlet 2 at the bottom, even when sucking up the cooling water in the reserve tank 1, it does not take up much space in a dead space as in the reserve tank shown in FIG. Since there is no D, all the cooling water in the reserve tank 1 can be sucked up.

In this way, in this embodiment, the radiator 5
When connecting the reserve tank 1 and the reserve tank 1 via a rubber hose, the shortest distance rubber hose 7 can be used for the connection, so there is no need to fix the rubber hose 7 midway to a vehicle or the like.

(g) Effects of the invention As explained above, according to the invention, a hose attachment port is provided near the top of the tank, a cooling water outlet is provided at the bottom of the tank, and a connection is provided to communicate the hose attachment port and the cooling water outlet. Since the pipe is integrated into the tank body, the length of the rubber hose that connects the radiator and reserve tank can be shortened, and there is no need to fix the rubber hose, and the cooling water in the reserve tank can be drained reliably. This excellent effect can be obtained.
