Description

Sprayer for an iron

The present invention relates to a spray device for an iron, at least comprising a fastening unit, a trunk unit and a spray unit, wherein the trunk unit has at least one means by which water from the fastening unit to the spray unit is convertible, wherein the spray unit has at least one opening, can be sprayed by the water.

Irons for irons are available in large numbers in the market. In this case, spray devices are part of the housing, are usually in the front of the tip of the housing, and are connected via a small hose or the like to the water tank. If the user actuates a corresponding actuating means, water is passed from the water tank to the spraying device. From there, the water is sprayed in the form of a fine mist on to be smoothed ironing.

The spray devices available in the prior art have a number of disadvantages. The fact that the spraying devices are firmly installed in the housing and integrated into the housing shape often results in part of the water to be sprayed not reaching the material to be ironed but running along the wall of the tip area of the iron. In addition, the spray devices available in the prior art are not able to spray larger amounts of water onto the ironing material. To compensate for this, the user has to press the actuating element several times under considerable force, in order to achieve the desired moistening of the ironing stock.

On this basis, it is therefore an object of the present invention to provide a spray device which avoids the disadvantages mentioned in the prior art, and offers the user a great versatility in terms of spray characteristics and advantageous ease of use.

This object is achieved by a spray device for an iron with the features of claim 1. Advantageous embodiments and further developments of the invention, which can be used individually or in combination with each other, are the subject of the dependent claims.

The spraying device according to the invention is based on generic spraying devices in that the spraying device has at least one fastening on its fastening unit, with the aid of which the spraying device can be removed by a user and can be exchanged for another spraying device.

As a result, a considerably improved ease of operation is achieved over the prior art. The fact that the user can now remove a spray of an iron and replace it with another spraying device, he has the ability to customize the spray characteristics of the iron more to his individual needs. Would he like smooth an ironing material made of a natural material such as e.g. Cotton exists and is relatively dense or thickly woven, so it will be advantageous for him to use a spray device that distributes as much water on the ironing. On the other hand, he is e.g. in an ironing material, which is particularly fine or thinly woven, choose a spray that distributes relatively little water as finely atomized on the ironing. Due to the device according to the invention, the user now has the opportunity to customize the spray characteristics of his wishes. In this case, the spray device 1, 2, 3, 4, 5, 6 or more openings.

In this case, the water to be sprayed is not heated substantially, but passes from a water tank, without being heated by a heating element, on the ironing material.

It is advantageous if the spray device has elastic properties. In a preferred embodiment, when the body unit is elastically formed, during spraying of the item to be ironed, the user can bend or bow the spraying apparatus in any direction to better reach the material to be ironed.

It has also proven to be advantageous if the means for replacement or for fastening has a screw and / or clamping and / or clip connection. If the fastening unit is connected to the housing via a screw connection, This ensures a particularly stable and at the same time waterproof connection. If, on the other hand, a clamping connection is selected, this enables a particularly rapid replacement of the spraying device with a simultaneously firm connection.

Furthermore, it is advantageous if the spraying device has an electrically operated pump. As a result, the user is relieved and improved its ease of use accordingly.

It has also proven to be particularly advantageous if the spray device has at least one piezo element, by means of which the water to be sprayed is finely distributed. An electronic control can be used to control the average droplet size of the mist.

Furthermore, it has proven to be advantageous if the piezoelectric element is controlled in such a way that the spray nozzle is automatically activated and deactivated again by the piezoelectric element in programmed cycles.

Furthermore, it is advantageous if the spraying device has a connection to a separate tank. Separately refers to separately from the tank, is discharged from the water for steam generation. Usually, a mixture of tap water and distilled water must be used to iron to avoid excessive calcification of the iron. If water is now advantageously supplied to the spray device from a separate water tank from which no water for steam generation is removed, pure tap water can be introduced into this separate tank, since this water is not heated, and the calcification problem only occurs during heating of the water Water occurs. If in this way a larger part of the water is sprayed cold instead of being brought in vapor form onto the material to be ironed, the calcification problem is reduced considerably and additional costs for distilled water can be avoided.

It is particularly advantageous if the iron is used as a dry iron. This means that in this advantageous embodiment, no or only small amounts of water is evaporated more, but the water is brought exclusively or almost exclusively as finely atomized mist on the ironing. Since that Water is not or only slightly heated, the Kalkproblematik is significantly reduced.

In a further preferred embodiment, the spraying device has means by means of which the quantities of water which can be conducted per unit of time through the spraying device can be regulated. This can e.g. a dial or a slider which changes, for example, the inner radius of the means for transferring the water or the water pipe in such a way that upon actuation of the spray function more or less water is conveyed through the spray device.

The spray device according to the invention has a significantly improved ease of use at the same time less burden on the user of the ironing device.

Further advantages and embodiments of the invention will be explained below with reference to various embodiments, to which the present invention is not limited, and with reference to the accompanying drawings.

In it show schematically:

Figure 1 is a side view of a spray device inserted into the housing.

In the following description of the preferred embodiments of the present invention, like reference characters designate like or similar components. Fig. 1 shows in a side view of a spray device 1 which has been inserted into a housing 11. Evident are a hull unit 3 and a spray unit 4. On the spray unit 4 sit three openings 6a, 6b and 6c. In this embodiment, the spraying device 1 was set at a position near the tip 7 of an iron 12.

Fig. 2 shows a side view of a housing 11 of an iron 12, in which the spray device 1 has been removed. Evident are a fixing unit 2, a trunk unit 3 and a spray unit 4. On the spray unit 4 sit three openings 6a, 6b and 6c, can be sprayed through the water. On the fastening unit 2, a fastening 10 can be seen, by means of which the spray device can be connected to the housing 11 of an iron 12.

The spray device 1 has a fastening unit 2 with a fastening 10, with which the spray device 1 is attached to the housing 11. In addition, the spraying device 1 has a hull unit 3 and a spray unit 4. On the spray unit 4 sit three openings 6a, 6b and 6c. In the interior of the hull unit 3, a means 5 for transferring the water passes. About this means 3 is a supply of the openings 6a, 6b and 6c with water. The water is taken from a water tank 9, transferred via the means 5 to the openings 6a, 6b, 6c and sprayed there on the ironing.

4 shows a further embodiment of a spraying device 1 in a perspective view obliquely from above. In this case, a spray unit 4 is extended sickle-like to the right and left. On this sickle-like extension sit openings 6 a to 6 d.
