Description
Technical Field
The present invention relates to an internal assembly of a laundry treatment appliance, in particular a vibrationally suspended internal assembly of a laundry treatment appliance, and a laundry treatment appliance having such an internal assembly.
Background
As shown in FIG. 1, the internal assembly 2 of a washing or centrifuge machine generally comprises a rinsing container
3 having a washing drum rotatably supported therein: (
Inner drum) 4 and in the form of an electric motor8, which motor drives the washing drum 4, often via a reduction gear or a gear change. The internal unit is suspended in a vibratable manner in the machine housing or in the robot housing 1 and forms a damageable, total system which generates resonance phenomena in a certain range of the rotational speed of the washing drum (below the rotational speed of the electric motor), which resonance phenomena may be caused by an imbalance in the load of the laundry. Due to the momentary unbalance in the load, a violent oscillation of the internal unit may occur. The resulting oscillations need to be recognized and avoided by specifying a corresponding target rotational speed in advance.
A solution is described in DE 102005037144B 4, in which the motor electronics 10 are fastened directly to the motor 8. This solution is not implemented on the market, however, because the motor electronics should be separated from the motor for logistics and warranty reasons. The technical defects of the traditional scheme are as follows: the motor electronics are spatially close to the hot motor and a housing is required to protect the motor electronics from dripping water.
Disclosure of Invention
Recognizing these practical situations, the object of the present invention is: an improved internal assembly of a laundry treatment apparatus is proposed, with which the above-mentioned drawbacks of the prior art can be eliminated.
According to the invention, this object is achieved by an internal assembly of a laundry treatment appliance having an immersion container, a washing drum rotatably mounted in the immersion container, an electric motor for driving the washing drum, and motor electronics for actuating the electric motor, wherein the motor electronics are mounted on the immersion container. The internal aggregate is preferably an vibrationally suspended internal aggregate. The motor electronics are preferably mounted on the immersion container by means of a molding provided on the immersion container for receiving the motor electronics.
By mounting the motor electronics directly on the immersion tank according to the invention, the motor electronics are spaced apart from the motor for driving the washing drum. The motor, which heats up during operation, therefore constitutes no problem for the motor electronics, so that only little effort is required for cooling and/or thermally insulating the motor electronics, with the result that the motor electronics can be designed in a simpler and more economical manner.
By mounting the motor electronics directly on the immersion container according to the invention, in particular by means of the shaping provided on the immersion container, additional protection of the motor electronics and additional fastening means for the motor electronics, for example in the form of a housing, a paint coating or the like, can be dispensed with or such measures can be made at least simpler.
In addition, the structural design of the present invention is more flexible and versatile/flexibly adaptable to new printed circuit boards (equipment). The separation of the motor electronics from the motor also has advantages in view of logistics and warranty. Another advantage resides in reduced complexity of the cable bundle and vibration circuit.
In an advantageous embodiment, the shaping is designed to shield the motor electronics from moisture, in particular to prevent water drops or splashes. The immersion cleaning container protects the motor electronics from water droplets and splashes of water droplets by its forming section. In a further advantageous embodiment, the shaping is designed to protect the motor electronics from mechanical influences, in particular against impacts on the housing of the laundry treatment appliance or on components connected thereto. The immersion cleaning container protects the motor electronics sufficiently by its formation to prevent collisions on the housing or parts connected thereto.
In an advantageous embodiment, the shaping part and/or the motor electronics have at least one opening for exchanging a fluid present in the shaping part, in particular water vapor or water, with the surroundings. For example, condensation water which is produced between the motor electronics and the rinsing container can flow out through the at least one opening.
In an advantageous embodiment, the motor electronics has a printed circuit board on which the components of the motor electronics are at least partially suspended. In particular, larger components such as chokes and heat sinks are mounted on the printed circuit board of the motor electronics in a downwardly suspended manner, so that the condensate flows down due to gravity and does not flow onto the printed circuit board.
The motor electronics are preferably connected to a dc voltage supply system for the purpose of supplying power. For this purpose, the motor electronics are preferably connected to the main control system of the laundry treatment appliance via power supply lines. The motor electronics can be supplied directly with dc voltage or have a rectifier to which ac voltage is supplied.
In an advantageous embodiment of the invention, the motor electronics have at least one vibration sensor or one rotational speed sensor. One or more vibration sensors are mounted on the motor electronics of the internal unit. Preferably, vibrations of the internal unit (for example due to an unbalanced load of the washing drum) can be detected by means of the at least one vibration sensor in order to actuate the electric motor accordingly. In particular, the rotational speed characteristic (drehzahlprofile) for driving the washing drum can be optimized by means of the at least one vibration sensor, which is part of the motor electronics, which is preferably rigidly connected to the immersion tank.
Preferably, the at least one vibration sensor is designed on the basis of a measuring principle using the capacitive effect, the inductive effect or the piezoelectric effect.
Preferably, the at least one vibration sensor is constructed and/or arranged to: the oscillation sensor can be used to detect a pivoting oscillation of the internal aggregate or of the immersion container of the internal aggregate about the first axis of rotation. The first axis of rotation is preferably oriented obliquely, in particular perpendicularly or substantially perpendicularly, to the drive axis of rotation defined by the bearing shaft of the electric motor and/or the washing drum.
Preferably at least two vibration sensors are provided. An imaginary straight line connecting the at least two vibration sensors is then preferably oriented parallel to the drive rotation axis.
In a further advantageous embodiment of the invention, at least one distance sensor is provided for measuring the distance between the internal assembly and the housing or a component fixedly connected to the housing. By means of this distance sensor, the load of the washing drum, that is to say the weight of the items of laundry in the washing drum, in particular the dry load or the quantity of water fed in before the washing program of the washing treatment appliance begins, can preferably be determined. In the case of an oscillating suspension of the internal aggregate, the immersion container and the washing drum are lowered in the housing against the spring force of the internal aggregate suspension, so that this lowering stroke can be detected as a measure for the load.
In a variant embodiment, the distance sensor has a transmitter arranged on the motor electronics and a receiver arranged on the motor electronics, wherein the transmitter and the receiver are preferably based on an optical measuring principle, and the transmitter and the receiver of the distance sensor interact with a reflective surface on the housing or on a component fixedly connected to the housing.
In an alternative or supplementary variant embodiment, the distance sensor has a transmitter or receiver arranged on the motor electronics and a receiver or transmitter arranged on the housing or on a component fixedly connected to the housing (for example a main control system of the laundry treatment appliance). The connection between the transmitter and the receiver is preferably realized by means of sensor wires for high resolution and fast data transmission.
In a further advantageous embodiment of the invention, at least one filter device is provided for suppressing low-frequency and/or high-frequency electromagnetic interference. The at least one filter device preferably has a harmonic reactor (oberwellendossel) for suppressing network harmonics (for example up to approximately 2 kHz), which is preferably arranged on the main control system of the washing treatment device, and/or a filter choke for filtering high-frequency interfering emissions (for example above 100kHz) of the converter output stage (Umrichterstufe) of the motor electronics. The filter choke for filtering high-frequency disturbances is preferably mounted directly on the motor electronics.
In an advantageous embodiment of the invention, the electric motor has a stator core which is electrically connected to the motor electronics, preferably to the voltage intermediate circuit of the motor electronics. The capacitive connection of the motor stator core to the reference potential of the motor electronics, preferably to one pole of the voltage intermediate circuit of the motor electronics, makes it possible to reduce the coupling of electromagnetic interference to the housing, the cable harness located therein or other electrical components. That is, the motor stator core may serve as shielding protection for motor phases of the motor that are synchronously clocked by the motor electronics.
By means of the two measures described above, the electromagnetic compatibility of the internal assembly, in particular with regard to the interfering emissions of the electric motor and the motor electronics, can be improved.
In a further advantageous embodiment of the invention, an electrical insulator is provided between the motor pulley of the electric motor and the rotor shaft of the electric motor. That is, the motor pulley of the motor is electrically insulated from the motor rotor shaft.
In a further advantageous embodiment of the invention, the motor electronics has a heat sink, preferably a heat sink with heat sinks. The heat sink is preferably designed as a Dome (Dome), particularly preferably as a plurality of domes.
The subject of the invention is also a washing treatment plant having a cabinet, a main control system and the above-mentioned internal unit of the invention. The washing processing apparatus is, for example, a washing machine (waschmashine, washing machine) or a washing and drying machine (dryer,
)。

The above and further features and advantages of the invention will be better understood from the following description of preferred, but not limiting, embodiments with reference to the attached drawings. Most of which are schematically shown:
FIG. 1 is a configuration of a washing machine with an internal assembly known from the prior art;
FIG. 2 is a configuration of a washing machine having vibrationally suspended internal machinery according to one embodiment of the present invention; and
fig. 3 shows the interaction of the individual components of the motor electronics of the internal assembly and other components in a greatly simplified manner according to an exemplary embodiment of the invention.
Detailed Description
Fig. 2 schematically shows a front view of the washing machine against the rear side of the washing machine housing 1, wherein said rear side is opposite to a filling opening, not shown. The internal unit 2 is vibratably suspended in the housing 1.
The internal unit 2 comprises a pickling container 3, a washing drum 4, a drum pulley 5, a transmission belt 6, a motor pulley 7 and a motor 8. In other words, the internal unit comprises all the components that form a common vibration system with the revolving washing drum 4. The vibration system is vibration insulated and/or vibration damped with respect to the cabinet 1 by means of suspension means.
The cylindrical immersion cleaning vessel 3 is oriented parallel to the bottom of the machine housing 1 or slightly inclined in its longitudinal extension. The immersion vessel 3 is thus arranged lying in the cabinet 1. The first side wall of the pickling container 3 faces a filling opening (not shown). In fig. 2, a rectangular coordinate system 9 with three axes X, Y, Z is shown. The axis marked X is oriented substantially parallel to the longitudinal extension of the pickling container 3.
The washing drum 4 is concentrically arranged inside the immersion container 3. The washing drum 4 is rotatably mounted, in particular in the rear wall of the immersion container 3, in the second side wall of the immersion container 3 facing away from the filling opening.
The washing drum 4 is connected to a drum pulley 5 in a rotationally fixed manner (i.e. rotationally fixed relative to each other). The drum pulley 5 is disposed concentrically with the washing drum 4. However, the drum pulley 5 is usually configured smaller in diameter than the washing drum 4.
A drum pulley 5 is provided on the side of the second side wall outside the pickling container 3. The drum pulley 5 is coupled to a motor pulley 7 via a drive belt 6. The motor pulley 7 is oriented parallel to the drum pulley 5. However, the motor pulley 7 is disposed offset toward the bottom of the housing 1. The motor pulley 7 is connected in a rotationally fixed manner to the rotor shaft of the electric motor 8, so that the motor pulley 7 can be driven by the electric motor 8. The washing drum 4 inside the immersion container 3 can be rotated via a belt drive consisting of a motor pulley 7, a drive belt 6 and a drum pulley 5.
If the drive belt 6 is not an insulator in the sense of a substantial insulation, the bearings of the washing drum 4 can be grounded (not shown). In a preferred alternative, the motor pulley 7 is provided with basic insulation means, for example in the form of a two-part pulley on the shaft of the motor 8, with an electrical insulation 7a located inside.
In an alternative embodiment, the washing drum 4 can be moved by a direct drive. The direct drive is located at the position of the drum pulley 5.
The suspension of the inner unit 2 is realized in the region of the ceiling of the housing 1 by means of springs 11. The springs 11 are each embedded with one end in a side area of the top plate side of the housing 1. The spring 11 is fastened with its other end at a different location on the internal aggregate 2, for example on the upper side of the immersion container 3.
Furthermore, a friction damper 12 in the bottom region of the housing 1 stabilizes the internal unit 2. The friction dampers 12 are each supported with one end in the lateral area of the housing 1. The respective other end is fastened at a different location on the side of the internal aggregate 2 facing the bottom of the cabinet 1, here on the underside of the immersion container 3.
The motor 8 is operated by motor electronics 10. The motor electronics 10 are not mounted on the electric motor 8 as in the conventional embodiment shown in fig. 1, but are mounted on the immersion container 3.
For this purpose, a special shaping 3a is provided, which is formed on the immersion container 3 or is fixedly connected thereto. The motor electronics 10 are received in this form part 3a, so that the motor electronics 10 are rigidly connected to the immersion container 3.
As illustrated in fig. 2, a main control system 20 is also provided in the housing 1, which supplies the motor electronics 10 with a direct or alternating voltage via supply lines 21 and is connected for data exchange to the motor electronics 10 via a communication line 22.
As is also illustrated in fig. 2, the motor electronics 10 are connected to the electric motor 8 via a connection 13 in order to control the motor phase of the electric motor 8. In addition, a connection 14 is provided between the motor electronics 10 and the stator core 8a of the motor 8.
The components of the motor electronics 10 are illustrated in greater detail in fig. 3, which greatly simplifies the construction and arrangement thereof.
The motor electronics 10 have, for example, a planar or 3D printed circuit board 24, which is rigidly connected to the immersion container 3. The printed circuit board 24 is in particular received in a formation 3a on the immersion container 3.
One or more openings 23 are formed in the printed circuit board 24, so that fluid (e.g. condensate water, water vapor) in the intermediate space between the printed circuit board 24 and the immersion container 3 can flow into the surroundings. In addition or alternatively, one or more openings can also be formed in the shaping section.
The motor electronics 10 includes a plurality of electronic components and a heat sink 28. In particular, the larger components (in the mounted state of the motor electronics 10) are mounted in a suspended manner on the printed circuit board 24. In this way, condensation water that may condense on the electronic components does not flow onto the printed circuit board 24, but may drip into the surrounding environment due to gravity.
The heat sink 28 serves in particular for cooling high-power components, such as a converter output stage (umrichterasgangsstufe) 31 of the motor electronics 10. The heat sink 28 is preferably provided with a plurality of heat sinks 29 in the form of domes.
The heat sink 28 receives additional forced ventilation, which is caused by the vibration of the internal aggregate 2 caused by the imbalance. The design of the heat sink with a low flow resistance in the X and Y directions is therefore advantageous for achieving the best possible cooling in all possible directions of deflection of the motor electronics 10 caused by imbalance. The heat sink 28 formed in this way may be a cast heat sink with a plurality of heat sinks 29 formed as domes. Alternatively, the heating body 28 protrudes beyond the end wall of the immersion container 3 to ensure better air circulation in the Z-direction.
The motor electronics 10 have a control device 35, for example a microprocessor, which is connected to the main control system 20 of the washing treatment appliance via a communication line 22.
On the printed circuit board 24 of the motor electronics 10, a rectifier 32 (which is supplied with an alternating voltage by the main control system 20 via the supply lines 21), a voltage intermediate circuit 30 and a three-phase converter output stage 31 are provided for actuating the three motor phases of the electric motor 8.
The motor electronics 10 can be switched on and off with switches via the main control system 20. To provide the mains voltage, the main control system 20 is connected to the motor electronics 10 via supply lines 21. In the embodiment shown in fig. 2, the supply line 21 supplies the motor electronics 10 with the mains voltage from the main control system 20. The mains voltage is rectified in the rectifier 32 of the motor electronics 10. The rectified ac voltage is supplied to the voltage intermediate circuit 30 at the motor electronics 10. In addition to the electric motor 8, other actuators, such as a circulation pump or a discharge pump, can also be supplied with current from the voltage intermediate circuit 30.
Alternatively, the motor electronics 10 can be supplied with a dc voltage. If the motor electronics 10 are supplied with dc voltage by means of the supply lines 21, the same voltage intermediate circuit 30 can be used in addition to the rectifier output 31 for controlling the electric motor 8 for further converter output stages on the main control system 20, which converter output stages are used for controlling further actuators, such as a circulation pump or a discharge pump.
The converter output stage 31 is connected to the electric motor via the connection 13. In addition, the potential of the stator core 8a of the electric motor 8 is conducted to the motor electronics 10 via the connection 14. In order to reduce the coupling of electromagnetic interference to the housing 1, the cable harness located therein or other electrically connected components, such as the heating device 16, the connection 14 on the motor electronics 10 is capacitively connected to the reference potential of the motor electronics 10. The connection 14 is preferably connected to one pole of a voltage intermediate circuit 30 of a converter output stage 31 for actuating the electric motor, so that the stator core 8a of the electric motor 8 acts as a shield for the motor phases which are synchronously clocked via the connection 13.
The motor electronics 10 usually generate disturbing low-frequency harmonic currents on the supply line 21, which harmonic currents must be suppressed. In addition, high-frequency electromagnetic interference is generated by a switching process in the power stage (Leistungsstufe) of the motor electronics 10, which switching process serves to actuate the electric motor 8.
The components for filtering the electromagnetic interference emissions are arranged as follows in the embodiment of fig. 3. A (heavy) harmonic reactor 33 for reducing the harmonics to a grid frequency of about 2kHz is provided on the main control system 20. The filter element for suppressing high-frequency interference is mounted in the vicinity of the source of the interference, preferably directly on the motor electronics 10. The filter device is, for example, a double choke 25 for filtering high-frequency electromagnetic interference emissions (> 100kHz) of a converter output stage 31 of the motor electronics 10.
Furthermore, the motor electronics 10 has one or more vibration sensors 26 for detecting vibrations of the internal aggregate 2, in particular of the rinsing container 3 thereof, and a control device 35 for detecting measured values of the at least one vibration sensor 26 and for actuating the electric motor 8.
The vibration sensor 26 is configured, for example: so that it can measure rotational or linear movements around the Y-axis and/or the Z-axis (coordinate system 9). Alternatively or additionally, angular or linear accelerations which are associated with such a rotational or linear movement can be measured by means of the vibration sensor 26. In particular, it is possible to measure the pitch nodding motion of the internal aggregate 2 (about the Y-axis) and/or the lateral yaw motion of the internal aggregate 2 (about the Z-axis) (gibberewegung). As a supplement, the vibration sensor 26 may be configured: vibrations around or in the X-axis can also be measured.
Preferably, at least two vibration sensors 26 are mounted on the motor electronics 10 and/or directly on the immersion container 3. The vibration sensor 26 is located on a (imaginary) straight line parallel to the drive rotation axis (X). In this case, the at least two vibration sensors 26 have as large a distance as possible from one another.
From the movement information of the at least two vibration sensors 26, the position of the center of gravity of the laundry inside the washing drum 4 can be precisely determined above the resting rotational speed (allegedmozahl) at which the laundry rests completely on the washing drum 4. The movement of the washing drum 4 inside the washing machine is thereby unambiguously determined and predictable.
Instead of at least two vibration sensors 26, one vibration sensor and one rotation speed sensor may also be used. In this case, the two sensors should preferably be mounted relative to one another in such a way that: the detection axes of the two sensors are overlapped.
For the vibrationally suspended internal unit 2, the load or filling level of the washing drum 4 or the weight loaded by the loaded laundry can be measured by measuring the settling distance (einnkweg) of the friction damper 12 or by comparing the position of the motor electronics 10 with a reference point fixed relative to the housing 1. The measurement can be based on optical, laser-optical, fiber-optical, acoustic, inductive or magnetostrictive measurement principles. Further preferred measuring principles are based on the principle of differential transformers, differential chokes (differential chokes) or by the determination of the sinking distance based on eddy current sensors.
In a reflection-based principle, such as the laser optical measuring principle, a transmitter 27a and a receiver 27b can be fitted to the motor electronics 10. The transmitter 27a and the receiver 27b of the distance sensor cooperate, for example, with a reflecting surface 34 on the bottom of the housing 1.
However, the control architecture according to the invention with the motor electronics 10 fastened to the immersion container 3 also offers the option of measuring the degree of filling via the sinking distance of the internal aggregate 2. Thus, the distance sensor can also be formed, for example, by a transmitter 27a ' on the main control system 20 and a receiver 27b ' on the motor electronics 10, which can be coupled to one another via a sensor line 27c '. Via the sensor line 27 c', an optical, acoustic or electromagnetic carrier signal can be transmitted, for example, in order to detect the relative position between the main control system 20 and the motor electronics 10. In a preferred embodiment, the sensor line 27c ' can be omitted if the digital communication signal between the transmitter 27a ' and the receiver 27b ' is sufficient, and the communication between the transmitter 27a ' and the receiver 27b ' takes place directly via the communication line 22. Since the main control system 20 is fixedly connected to the cabinet 1, the absolute sinking of the immersion container 3 when it is loaded with laundry can be measured and the weight of the load can then be determined via the spring constant of the spring 11. Here, it is preferable that the main control system 20 is mounted on the cabinet 1 of the washing process apparatus in the vicinity of the motor electronics 10. As a result, signals can be received between the transmitter 27a 'and the receiver 27 b' with the best possible resolution without interference. Alternatively, the positions of the transmitter 27a 'and the receiver 27 b' may be interchanged.
