Description

The The invention relates to an ironing board for steam ironing with an air-permeable Ironing surface, one arranged on the ironing surface Trough, a means for generating an air flow through the ironing surface and the tub and with at least one sensor, the sensor in or in the area of the ironing board, in particular the means for generating an air flow, the Pan and / or the ironing surface predetermined Way of air flow is appropriate.

From the Patent Abstract of Japan with the publication number JP 5228299 is an ironing board with the features mentioned above known. By means of the moisture sensor, the moisture of the laundry is detected indirectly. The moisture of the laundry is an important factor for the success of the ironing process, in particular for achieving the desired smoothness of the laundry article. The humidity sensor is provided in the area of a fan. The humidity of the air flowing through the fan is detected, and according to the humidity of this air, steam generation in the iron is controlled. The control is also to avoid too high a generation of steam.

at the famous ironing tables is the fan or the means for generating the air flow through the ironing surface and the tub usually constantly switched on. Independently from the humidity, from the performance of the steam generator and the current use of the ironing board or iron the means for generating the air flow constantly bring the preset power. The generation of the air flow is connected to a certain noise level, which is caused by the operation of the fan. This noise can and is often used by users of steam ironing tables unpleasant and disturbing felt, especially if the user in addition to the ironing activity at the same time a conversation leads, Radio listens, watching TV or talking on the phone.

Here uses the present invention.

The present invention solves the problem, the noise level generated during operation of the ironing board to minimize.

This Problem is solved by that the ironing board a means for controlling and / or regulating the means for generating the air flow having, on the one hand with the sensor and on the other hand with the Connected means for generating the air flow is.

The For example, means for controlling and / or regulating may be appropriate and being arranged, the means for generating the air flow when passing of at least one value measured by the sensor is higher than to turn on a predetermined first value. Likewise it is possible that the means for controlling and / or regulating suitable and furnished is below one of a value measured by the sensor predetermined second value to turn off the means for generating the air flow. The first value is advantageously smaller than the second value. In This simple implementation of the invention will be the means for generating the air flow from the means for controlling and / or regulating depending on measured value on or switched off. As a result, the means is already turned off in a large part of the time stay that way, so no disturbing noise arises.

The Means for controlling and / or regulating may also be arranged that the power of the means for generating the air flow in dependence of the value measured by the sensor. For example measured a high value, which may not be optimal and a high noise generation the power is increased, for example, by the fact that the speed of a fan is increased.

The Power of the means for generating the air flow, for example, proportional be set to the measured value.

at The sensor may be a humidity sensor or a sensor Warmth- or temperature sensor act. Several sensors can be used which measure humidity and / or temperature. All sensors then preferably give their readings to the means for controlling and / or Rules that can evaluate the measured values and, if necessary, link them internally.

Of the Moisture sensor may be a resistive or a capacitive humidity sensor be. Any other type of moisture sensor can basically, as far as it is suitable to be used.

One embodiment for one ironing board according to the invention becomes closer with the drawing shown. It shows

1 a perspective view of the ironing board with removed ironing surface and

2 a perspective view from below of the ironing board.

The ironing board according to the invention has a scissors-type frame 4 with two hinged supports 41 and feet 42 on. The scissor frame is with a support 41 articulated with a tub 2 the ironing board 1 connected while the end of the other prop 41 in different locking positions 24 at the bottom of the tub 2 for setting up the ironing board 1 can be determined.

The tub 2 the ironing board is on the one hand self-supporting and also carries the ironing surface not shown in the figures which the tub 2 closes on top, leaving between the ironing surface and the tub 2 a cavity is created.

The ironing surface can in any way with a peripheral edge 21 the tub 2 get connected.

The ironing surface of the ironing board according to the invention 1 is made of expanded metal mesh. In addition, however, any other type of air-permeable surface comes into question.

At a front end of the tub is a housing 5 arranged in which various electrical components, including a means for controlling and / or rules is housed. Also, at the same end of the tub 2 a shelf 3 intended for a steam ironing station.

On the bottom of the tub is in the area of the same end of the tub 2 a means for generating an air flow, with which an air flow through the trough and the ironing surface can be generated. The means for generating the air flow can be adjusted so that there is an air flow from the tub 2 sucks or pushes into the tub. The means for generating the air flow, which can be formed by a simple fan, is controlled by the means for controlling and / or regulating.

Inside the tub 2 is a humidity sensor 7 arranged, the moisture within the cavity between the ironing surface and the tub 2 recorded and reported to the means for controlling and / or rules. The moisture sensor may basically be located anywhere within the tub or at the bottom of the ironing surface. A plurality of humidity meters may also be arranged, the signal of which is processed by the means for controlling and / or regulating in order to control the means for generating the air flow.

By the inventive control of Means for generating the airflow can be achieved that the means for generating the air flow only then work when it is necessary. In the remaining time, the means for generating the air flow remain switched off, which reduces the power consumption on the one hand and on the other hand also noise emissions be avoided.
