Description
Description
A DRYER COMPRISING A DRYNESS SENSOR
[0001] The present invention relates to a dryer comprising dryness sensor.
[0002] As is known, in dryers, various embodiments for sensing the dryness of laundry are available. One of these embodiments is based on the principle that at least two electrodes are disposed to a point where the laundry will contact during the drying process and that a current bridge is formed between the electrodes when the damp laundry contacts both electrodes simultaneously. Dryness sensing can be performed by examining the difference between the resistance values of the electrodes.
[0003] In the state of the art, in order to increase the measurement efficiency and to provide ease of assembly, various embodiments have been developed relating to where these conductive elements used in dryness sensing will be disposed inside the dryer and how they will be assembled.
[0004] In the state of the art United States of America Patent No US3593571 , a dryer wherein the electrodes are fastened by means of clip means is explained.
[0005] Another state of the art embodiment is explained in the European Patent Application No EP1473402. In this embodiment, the electrodes are mounted on a sensor body and the sensor body is secured to the front bulkhead of the dryer by mechanical connection methods such as screw and detent.
[0006] In another state of the art embodiment, the United States of America Patent No US4899464, a dryer that comprises electrodes which are snap-fittingly seated in the housings seated on the front bulkhead is explained.
[0007] Another state of the art document is the United States of America Patent No US5940986. In this document, a dryer wherein the electrodes are embedded on the plastic exhaust vent cover by heat staking is explained.
[0008] However, in these state of the art embodiments, albeit small, a space cannot be prevented from remaining between the electrodes and the surface whereto the electrodes are fixed, and the filling of fluffs departed from of laundry to these spaces in the course of time adversely affects the
measurement precision. On the other hand, as being an additional assembly step during the production of the dryer, the assembly of the electrodes increases the labor time and cost.
[0009] The aim of the present invention is the realization of a dryer wherein the dryness sensing electrodes are assembled easily and efficiently.
[0010] The dryer realized in order to attain the aim of the present invention is explicated in the attached claims.
[0011] The dryer of the present invention comprises a fixing surface produced such that the electrodes used for dryness sensing are inserted into the mould and at least partially embedded in the fixing surface. The fixing surface is produced from a dielectric material and fixed to the bulkhead. Thus, a space wherein the fluffs departed of laundry can be jammed is prevented from remaining between the fixing surface and the point whereto the electrodes are fixed, and thus, the measurement efficiency is increased.
[0012] In different embodiments of the present invention, the fixing surface is produced in a way integrated to the bulkhead or is fixed to the bulkhead by an assembly element.
[0013] In the preferred embodiment of the present invention, the electrode comprises a body and two extensions which are located at both sides of the body and which remain inside the fixing surface. The body is cambered such that it will provide a protrusion to be formed on the fixing surface. Thus, the laundry is provided to easily contact the electrodes.
[0014] The model embodiments that relate to the dryer realized in order to attain the aim of the present invention are illustrated in the attached figures, where:
[0015] Figure 1 - is the sideways schematic view of a dryer.
[0016] Figure 2 - is the perspective view of the bulkhead.
[0017] Figure 3 - is the detailed front view of the bulkhead, the fixing surface and the electrodes.
[0018] Figure 4 - is the view of detail A in Figure 3.
[0019] The elements illustrated in the figures are numbered as follows: 1. Dryer
2. Drum
3. Bulkhead
4. Opening
5. Electrode
6. Fixing surface
7. Body
8. Extension
[0020] The dryer (1) of the present invention comprises a drum (2) which is rotated around the horizontal axis, a bulkhead (3) which has an opening (4) that enables the laundry to be loaded into the drum (2) and to be unloaded therefrom, and at least two electrodes (5) which are fixed to the bulkhead (3) and which provide dryness sensing to be performed (Figure 1 and Figure 2).
[0021] The dryer (1), furthermore, comprises a fixing surface (6)
- which is fixed to the bulkhead (3),
- which is formed by a plastic material being injected onto the electrodes (5),
- wherein the electrodes (5) are partially embedded (Figure 3). [0022] After the electrodes (5) are positioned into the mould wherein the fixing surface (6) will be produced, the fixing surface (6) is formed preferably by the plastic injection method. Thus, by providing the assembly of the electrodes (5) without a space and in a leak proof manner, both the dryness measurement is provided to be performed more correctly and the need of additional connecting element is eliminated and hence, the assembly cost is minimized.
[0023] In an embodiment of the present invention, after the electrodes (5) are embedded in the fixing surface (6) during its production, the fixing surface (6) is fixed onto the bulkhead (3) by means of an assembly element.
[0024] In an embodiment of the present invention, the fixing surface (6) is produced as one piece with the bulkhead (3).
[0025] In the preferred embodiment of the present invention, the electrode (5) is arcuately shaped and comprises a body (7) which forms a protrusion outwards from the fixing surface (6), and at least two extensions (8) which
are located at both sides of the body (7) and which are embedded in the fixing surface (6) (Figure 4). The arcuate structure of the body (7) facilitates the contact of the laundry to the electrodes (5) during the dryness measurement and thus, effective dryness measurement is provided. It is to be understood that the present invention is not limited to the embodiments disclosed above and a person skilled in the art can easily introduce different embodiments. These should be considered within the scope of the protection postulated by the claims of the present invention.
