Abstract
Description
- The present invention relates to a washing machine with a wash drum lighting device.
- As is known, last-generation household washing machines are equipped with a lighting device, normally located inside the wash chamber of the machine to illuminate the drum, so that the laundry inside the drum is visible to the user during and/or at the end of the wash cycle.
- More specifically, the lighting device comprises a halogen or incandescent lamp located inside the wash chamber, at the door opening of the machine, and oriented to light the inside of the drum; and an electric control circuit for supplying the lamp with a given electric power.
- The washing machine lighting device described above has various drawbacks.
- Firstly, in addition to requiring a large amount of electric power, with obvious drawbacks in terms of consumption, the incandescent or halogen lamps of lighting devices of the above type also have the major drawback of high operating temperature. As a result, to keep the lamp at a stable temperature below a given danger threshold, highly complex electronic control circuits are required to control power supply to the lamp as a function of the temperature of the lamp, and so prevent overheating and the risk of fire.
- Secondly, halogen or incandescent lamps indiscriminately illuminate all the space surrounding the lamp, as opposed to producing a light beam directed solely onto the drum area to be illuminated. In point of fact, a large percentage of the light beam emitted by the lamps of currently used lighting devices is wasted.
- Finally, the working life of lamps of lighting devices of the above type is seriously affected by the degree of machine vibration and the number of switching operations of the electric control circuit. As a result, the lamp is frequently damaged when subjected to severe vibration or when a given switching threshold is reached.
- It is an object of the present invention to provide a washing machine comprising a wash drum lighting device designed to eliminate the drawbacks of known lighting devices.
- According to the present invention, there is provided a washing machine comprising a wash drum lighting device as claimed in the accompanying Claims.
- A non-limiting embodiment of the present invention will be described by way of example with reference to the accompanying drawings, in which:

LEDs 9,lens 11 provides for appropriately collimating the light beams fromLEDs 9 onto wash drum 7. - In the Figure 2 example,

shell 10 is provided on the end with a number of axially spacedlock seals 15, which, on the one hand, seal the end ofseat 12 facing wash drum 7, to protectLED 9 against water, and, on the other, assist inlocking shell 10 axially insideseat 12. - Shell 10 also has two
longitudinal anchoring flanges 16, which project from the opposite end ofshell 10 tolens 11, are positioned facing and parallel to each other, and the free end of each of which has a supportingedge 16a which, whenshell 10 is fitted insideseat 12, rests on the end edge ofseat 12 opposite wash drum 7 to prevent axial movement ofshell 10 towards wash drum 7. - Supporting
rod 13 is substantially cylindrical, is made of metal, such as aluminium or any other similar metal material, and provides for dissipating into the outside atmosphere the heat generated byLED 9. - The body of
rod 13 has two longitudinal grooves 17 (only one shown in Figure 2), each for housing a portion of conducting wire ofLED 9; and two anchoring tabs 18 (only one shown in Figure 2) which fit inside respective seats (not shown), formed in the inner walls oftubular cavity 14 ofshell 10, to mechanically connectrod 13 andshell 10 into one body. - Seat 12 is substantially complementary in shape to the outer shape of

power block 20 may be defined by an electronic PWM (Pulse Width Modulation) circuit connected to the two input terminals ofLED 9 to supply electric power to the LED, and having an input supplied with a control signal SCOM indicating the electric power to be supplied toLED 9. - Detecting
block 21 is input-connected to the two input terminals ofLED 9, and has an output supplying a current/voltage signal ST proportional to the junction temperature TG ofLED 9; andcontrol block 22 receives and processes signal ST to produce, as a function of the junction temperature TG reading, signal SCOM coding the value of the electric power to be supplied toLED 9. - More specifically,
control block 22 may be defined by a microprocessor, which compares the temperature TG reading with a predetermined maximum temperature threshold TS, and, in the event the temperature TG reading exceeds the predetermined maximum temperature threshold TS, provides for controllingpower block 20 to reduce the electric power supply toLED 9 and so reduce the junction temperature ofLED 9. - In other words,
electronic control unit 19 acts as an electronic closed-loop circuit, which controlsLED 9 to keep its junction temperature stable below the predetermined maximum temperature threshold TS. -

lighting device 8 comprises a multicolour RGB diode or a number of LEDs of different colours, the colour of the light beam directed onto wash drum 7 can be varied as a function of the operating conditions and/or operating status ofwashing machine 1. -
Electronic control unit 19 is able to control the multicolour RGB diode to generate a light beam with a frequency spectrum, i.e. a colour, associated with a given operating condition or a given operating status of the washing machine. - More specifically,
electronic control unit 19 may control the multicolour RGB diode or the LEDs to generate a light beam of a predetermined first colour, e.g. red, when the operating status corresponds to the start of the wash cycle; and/or to generate a light beam of a predetermined second colour, e.g. green, when the operating status corresponds to the end of the wash cycle; and/or to generate a light beam of a predetermined third colour, e.g. yellow, whenwashing machine 1 is in an intermediate wash cycle status. - Emission of different-coloured light beams may be activated by
control block 22 on the basis of an information signal SINF supplied to controlblock 22 by an additional external control module for controlling and monitoring the operating status ofwashing machine 1. -
Lighting device 8 ofwashing machine 1 described above has numerous advantages. - Firstly, using
LED 9 provides for : reducing electric power consumption in use; and reducing the heat produced during emission of the beam, also by virtue of the heat-dissipating function performed by supportingrod 13. - Secondly, using
LED 9 advantageously provides for concentrating the projected beam solely on the opening of wash drum 7, thus reducing light dispersion outside the drum. - Thirdly,
lighting device 8 has the major advantage of coding the operating status ofwashing machine 1 by means of a predetermined colour, thus enabling the user to determine the current operating condition ofwashing machine 1 quickly and easily, even at a distance from the machine, simply on the basis of the colour of the light projected onto the drum. - Clearly, changes may be made to the washing machine and lighting device as described and illustrated herein without, however, departing from the scope of the present invention as defined in the accompanying Claims.
