The synthetic resin water tank 25 composed of the tank base 26 and the tank cover 27 is generally made of a polycarbonate resin as a resin material in order to obtain sufficient strength and transparency.

When manufacturing the water tank 25, the tank base 26 and the tank cover 27 made of the polycarbonate resin are set inside the two welding jigs a and b as shown in FIG. Ultrasonic vibration is applied to the jigs a and b, and as shown in FIG.
The water tank 25 is formed by a method of welding the tank tank 27 to the water tank 25.

If a high-rigidity material such as polycarbonate resin is used, the tank base 26 and the tank cover 27 can be properly welded by the means shown in FIG. 5, but a high-rigidity material such as polycarbonate resin is expensive. Therefore, there is a problem that the manufacturing cost of the water tank 25 is considerably increased.

Therefore, it is conceivable to use an inexpensive material such as a polypropylene resin. However, such a resin material has low rigidity. Therefore, when welding is performed by the means shown in FIG. 27 cannot be pressed firmly, the energy of the ultrasonic vibration is attenuated, and it becomes difficult to secure sufficient welding strength and watertightness.

Therefore, the water tank 25 in this embodiment is
Here, the tank base 26 and the tank cover 27 are welded by taking the following means. That is, in this embodiment, the material of the tank cover 27 is a thermoplastic resin having high transparency, and the material of the bottom plate 25 is a thermoplastic resin having high heat resistance.

Is pressed down, and the lower side of the flange portion 37 of the tank base 26 is pressed by the welding jig b. In this state, the welding jig b
The projection 38 is melted by applying ultrasonic vibrations to the lower surface of the tank base 26 by bringing the lower surface of the horizontal wall 35a of the step portion 35 into contact with the upper surface of the flange portion 37.
And the tank cover 27 are connected in a watertight manner. At this time, the melted projections 38 are filled in the gaps h1 and h2, and the molten material of the projections 38 is transferred to the water tank 2.
There is no protruding inside or outside of 5.

As shown in FIG. 7, the tank base 26 has ribs 39 at the front and rear portions in the longitudinal direction. The rib 39 has a dimensional relationship in which it comes into contact with the inner surface of the peripheral wall of the tank cover 27 after the welding of the tank base 26 and the tank cover 27, so that even if an excessive force or impact is applied to the welding portion from the outside after the welding, the welding is performed. The shear stress applied to the welded portion can be reduced, and water leakage due to breakage of the welded portion can be prevented.

As shown in FIG. 9 (A), a boss 40 is integrally protruded from the tank cover 27 at the welded joint between the tank base 26 and the tank cover 27.
This boss 40 can be inserted into the through hole 41 of the tank base 26, and the tip of the boss 40 can be crushed and welded as shown in FIG. 9B at the time of welding. Thereby, even if an unreasonable force or impact is applied to the welded portion from the outside after welding, the shear stress applied to the welded portion can be reduced, and water leakage due to breakage of the welded portion can be prevented.

It is also possible to adopt a construction in which an antibacterial agent is mixed in the resin material for forming the tank base 26 and the tank cover 27 to prevent the growth of various bacteria in the water tank 25.

As described above, in the water tank 25 of the present embodiment, the step 35 extending outward is formed integrally with the opening edge at the lower end of the tank cover 27, and the tank base 26 is provided inside the step 35. The flange 37 is fitted so that the upper surface of the flange 37 is opposed to the horizontal wall 35a of the step 35. In this state, ultrasonic welding is applied to the welding jig b to perform welding. Sufficient welding strength and water tightness can be obtained without attenuating vibration energy, and inexpensive polypropylene resin or the like can be used as a material, and a low-priced, highly rigid water tank 25 can be manufactured. .
