Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a steam iron for general household use.

Conventional technology Conventional steam irons of this type include, for example,
It had the configuration shown in Japanese Utility Model Application No. 100436/1983, and specifically as shown in FIGS. 8 and 9.

That is, a water inlet cover 1 equipped with a resin spring part 2
is slidably provided between the water tank 3 and the tank cover 5, and is adapted to open and close the water inlet portion 4.

Problems to be Solved by the Invention However, with such a structure, even if water is poured into the water tank 3 from the water inlet part 4 and the water inlet cover 1 is closed, the sliding between the water inlet cover 1 and the water tank 3 is There was a problem that a gap was likely to be formed between the moving surface 3' and water could not be reliably sealed. This is due to the following reasons.

In other words, the water inlet cover 1 is set between the sliding surface 3' of the water tank and the tank cover 5, but since the shape of the water inlet cover 1 is a flat plate, it is likely to warp or bend when molded. It was necessary to manage this by controlling the gap between the sliding surface 3' of the water tank 3 and the tank cover 5; if the gap was too large, the sealing performance would be poor, and if the gap was too small, the sliding of the water inlet cover 1 would become hard. Furthermore, when the resin spring 2 provided on the water inlet cover 1 wears out, the sealing performance deteriorates, causing water leakage.

Therefore, the present invention aims to ensure that the water inlet is closed by the water inlet cover, and to smoothly open and close the water inlet.

Means for Solving the Problems In order to achieve the above object, the present invention has the following features:
A water tank, a water inlet formed in the water tank,
A water inlet is provided at a position facing the water inlet, and a tank cover is attached to the water tank with a gap between the water inlet and the water inlet, and the tank cover and the water tank are connected to each other. A seal part that is slidably disposed between the water tank and is in contact with a sliding surface on the tank cover side of the water tank provided with the water inlet, and a hollow part is provided between the seal part and the water tank is connected to the water tank. and a water inlet lid having a pressurizing portion biased toward the tank cover.

Effect The effect of this technical means is as follows.
In other words, the seal part of the water inlet cover is connected to the seal part with a hollow part provided therebetween, and the seal part is connected to the water tank with the water inlet provided by the pressurizing force from the pressurizing part that is biased toward the tank cover side. This allows the tank cover to be pressed against the sliding surface of the tank cover, making it possible to reliably seal and close the water inlet.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings. 1 and 2, reference numeral 6 denotes a water inlet cover made of thermoplastic resin such as PP, ABS, etc., which includes a seal portion 6a that opens and closes the water inlet 8 in contact with the sliding surface 7' of the water tank 7; This seal part 6
A pressurizing part 6 that is connected with a hollow part 6' between the pressurizing part 6 and the
b is integrally formed. Reference numeral 9 denotes a tank attached to the water tank 7, with a water injection part 9a provided at a position facing the water injection port 8 of the water tank 7, and a gap 9b provided between the water injection part 9a and the water injection port 8. During this time, close the water inlet cover 6 with the cover 9b
It is slidably installed inside.

Next, the operation of the configuration of this embodiment will be explained.

First, when the water inlet cover 6 is set on the water inlet part 8 of the water tank 7 via the tank cover 9, the pressurizing part 6b of the water inlet cover 6 is bent, and its elastic force causes the seal part 6a to be filled with water. Pressure is acting in the direction of the water inlet 8 of the tank. By using this pressure, if the sliding surface 7' of the water inlet cover 6 in the water tank 7 and the shape of the seal portion 6a are made to match, a state of close contact will always be maintained and the sealing performance will be stable.

As a result, water in the water tank 7 will not leak from between the water inlet cover 6 and the water inlet portion 8. Further, in this embodiment, since the water inlet cover 6 itself has the pressurizing part 6b and the sealing part 6a, the pressurizing part 6b
Even if it wears out, the elastic force works to maintain sufficient sealing performance, and no water leaks occur.

Next, other embodiments of the present invention will be described.

3 to 7 show other embodiments, first of all, FIG. 3 shows a portion of the pressurizing portion 6b of the water inlet cover 6 cut away. In this case, the seal portion 6a is the water tank 7.
If the water inlet part 8 is covered, water will not leak.
By cutting out a portion of the pressurizing portion 6b of the water inlet cover 6 in this manner, the elastic force can be adjusted, and furthermore, material costs can be reduced.

FIG. 4 shows various shapes of the seal portion 6a of the water inlet cover 6. In other words, by matching the shape of the seal portion 6a of the water fill port lid 6 to the shape of the water fill port portion 8 of the water tank 7 and the water fill port lid sliding surface 7', sealing performance is maintained and water leakage is prevented. be able to.

FIG. 5 shows that the thickness of the seal portion 6a of the water inlet cover 6 is made thicker than the pressurizing portion 6b to prevent warping or deformation of the seal portion 6a and to reduce the thickness of the pressurizing portion 6b. By changing the pressure, it is possible to adjust the sealing pressure between the seal portion 6a of the water fill port lid 6 and the water fill port portion 8 of the water tank 7.

In FIG. 6, a convex part 12 is provided at one end of the pressurizing part 6b of the water inlet cover 6 to produce a click feeling, and when the water inlet cover is closed or opened, the tank cover 9 is attached to the tank cover 9 in accordance with the position of the convex part 12. A groove portion 13 is provided.

Conventionally, a click device is provided between the plate-shaped water inlet cover (Fig. 8) 1 and the water tank 3, so when the tank cover 5 is set, the water inlet cover is always pressed against the tank cover side. I will receive it,
A gap is created between the water inlet cover 1 and the sliding surface 3' of the water tank, which tends to cause water leakage, and it is very difficult to manage the gap between the water tanks in order to prevent this. However, by providing the click device between the pressurizing part 6b of the water inlet cover and the tank cover 9 as in this embodiment, the sealing part 6a of the water inlet cover is always pushed toward the water tank 7, In addition to stabilizing the sealing performance, the tank cover 9
This makes it easier to manage the gap between the water tank 7 and the water tank 7.

Further, in this click device, a similar result is obtained when a groove is provided on the pressure part 6b side of the water inlet and a convex part is provided on the tank cover 9 side as shown in FIG.

Effects of the Invention As described above, the steam iron of the present invention is provided with a tank cover of a water tank that is slidably disposed between a tank cover attached to a water tank and the water tank, and is provided with a water inlet. The tank cover includes a seal portion that contacts the side sliding surface, and a water inlet lid that is connected to the seal portion with a hollow portion provided therebetween and has a pressurizing portion that is biased toward the tank cover side. This allows the pressurizing part to slide with the seal part in close contact with the sliding surface of the water tank,
The water inlet cover allows the water inlet to be opened and closed reliably, and also allows for smooth opening and closing of the water inlet by reducing variations in operating load.
