Definitions
- Refrigeration device with a retaining clip for a fan motor
- the invention relates to a refrigeration appliance, in particular household refrigerating appliance, comprising a fan housing of a cooling air circulation circuit with a motor mount and a fan wheel rotatably mounted in the fan housing, which is attached to a shaft of an engine mounted on the engine mount.
- a no-frost refrigeration device is known, with an evaporator, which is supported on a evaporator chamber partitioning off against a cold room carrier with a wall, wherein in the wall of the carrier, a passage to an air duct is formed , and a fan mounted vibration-damped on the passage, and the fan is supported by a passage member opposite wall member of the air duct and the wall member is fixed to the support via vibration-damping elements.
- a no-frost refrigeration device is known, with an evaporator, which is supported on a evaporator space against a cold room severing carrier with a wall having a passage therein, through which of a fan circulated air flows, wherein on the wall of a web, which forms a boundary wall of a communicating via the passage with the housing interior air duct, is formed projecting on an outer side of the wall.
- the object of the invention is to provide improved storage of a motor-driven fan wheel in a cooling-air recirculation circuit of a refrigeration appliance, in particular domestic refrigeration appliance, in particular to design the storage with low noise and cost.
- a refrigeration device in particular domestic refrigeration appliance, comprising a fan housing of a cooling air circulation circuit with a motor mount and a fan housing rotatably mounted fan wheel, which is attached to a shaft of an engine mount mounted on the engine mount, wherein the motor to the engine mount of Fan housing is mounted by means of a retaining clip which is mounted on the motor mount in a resilient manner.
- the motor mount may be formed on the fan housing, in particular integrally formed, preferably einstoffig.
- the retaining clip may be mounted by a latching connection to the motor mount in a resilient manner, in particular such that the retaining clip is held braced against play against the engine mount.
- a latching connection By the latching connection, a play-free mounting of the retaining clip can be achieved on the motor mount, in particular without requiring separate fasteners or to vote the components with each other in terms of their component tolerances particularly.
- the locking connection itself is formed without play.
- a backlash-free locking of the retaining clip on the motor mount means that there is no freedom of movement due to production or application in which the retaining clip can be moved freely after its mounting on the motor mount without force transmission.
- the locking connection is also designed for tension-free mounting of the engine.
- a stress-free locking of the retaining clip on the motor mount means that the freedom of play of the latching is not achieved by tension forces, resulting from a strained bearing of the engine. Rather, the retaining clip is locked independently of the engine backlash on the engine mount.
- the holder according to the invention has a latching connection and a resilient mounting the advantage that the vibrations generated by a fan motor assembly are not transmitted unattenuated as structure-borne sound to the fan housing.
- An undamped transmission of this structure-borne sound to the fan housing would have the disadvantage that noises could be perceived by a user of the refrigerator or would be distracting.
- the fan housing is arranged, for example, in no-frost devices within the cooling space, vibrations which are caused by the fan-wheel motor arrangement and as structure-borne noise and as airborne noise would Sound are transmitted to the fan housing, as noises are perceived in the refrigerator.
- the holder of the retaining clip according to the invention via a snap connection and a resilient mounting has the advantage that separate vibration damping elements can be omitted and thus the variety of parts is reduced and the refrigeration device can be produced more cheaply.
- Another advantage is that a large opening in the fan housing that is present when using vibration damping elements can be dispensed with, so that the entry of airborne noise into the fan housing is prevented or significantly reduced.
- a large circular opening can be sufficient according to the invention, two narrow slots in a wall of the fan housing.
- a connection in the axial direction by means of vibration damping elements i. Bearing rubber obtained by overstretching the motor retaining clip on the motor holder.
- a support in the radial direction is neglected in this case. not ensured and can lead to noise because the motor retaining clip can beat in the motor holder. is not stored without clearance.
- the vibration damping in the use of vibration damping elements in the axial direction only in conjunction with the motor and the vibration damping elements i. Storage rubbers achieved. In other words, the vibration-damping function of the bearing rubbers is minimized by the overstretching of the motor mount at the expense of the vibration-damping engine mount in the axial and radial directions.
- the inventive holder of the retaining clip via a snap-in connection and a resilient mounting ensures a horizontal ie axial clearance-free attachment and a vertical ie radial clearance-free attachment, and a vibration and thus noise damped attachment of the motor or the retaining clip of the motor on the fan housing. This is guaranteed regardless of the bearing of the engine and bearing rubbers. Due to the inventive holder of the retaining clip via a latching connection and a resilient mounting not only the retaining clip with respect to the motor mount horizontally and vertically vibration damped, but also by the remaining drive shaft rubbers a balanced horizontal and vertical vibration damping of the motor on the retaining clip possible. The retaining clip is thus by means of the locking connection without play, ie rigidly connected to the fan housing.
- the retaining clip By means of flexurally elastic mounting of the retaining clip, in particular by a flexurally elastic middle web of the retaining clip and / or by flexurally elastic spring elements, in particular spring tongues, the retaining clip is mounted vibration-damped on the motor mount.
- the retaining clip may have latching means, which locks the retaining clip in the axial direction of the drive shaft and in a radial direction to the drive shaft resiliently on the motor mount.
- the latching means according to the invention are designed such that on the one hand fix the retaining clip to the motor mount and on the other hand in the axial direction of the drive shaft and in a radial direction to the drive shaft allow a resilient movement of the retaining clip, so that vibrations of the fan-motor assembly not or only vibration damped transferred to the motor mount.
- the retaining clip may be bow-like with a central web, which has a bearing point for a rear side of the engine and two opposite, the locking means having legs formed.
- the motor is frontally supported by a wall portion of the fan housing and back of the central web of the retaining clip.
- the front wall portion of the fan housing may have the same size and / or the same contour as the central web of the retaining clip.
- From the central web two legs can extend away from the plane of the central web substantially at right angles.
- the two legs extend from the central web on opposite sides of the engine in the axial direction forward to the engine mount.
- the mounting plug direction extends in the longitudinal extent of the legs or in a direction parallel to the axial extent of the drive shaft.
- the retaining clip to form a force acting in the axial direction of the drive shaft spring preload two opposing legs having latching means which engage in corresponding counter-latching means on the motor mount play and a connecting the two legs connecting web be designed to be flexible.
- the Locking means locked so play with the counter-locking means.
- a resilient damping in the axial direction of the drive shaft is effected by the resilient ie flexurally elastic center web.
- the latching means can be formed, for example, by openings in the legs of a clip-type retaining clip, which interact with corresponding latching projections of the motor mount.
- the locking means can be formed by locking projections in the legs of a bow-shaped retaining clip which cooperate with corresponding openings of the motor mount.
- the two legs of the retaining clip and the corresponding locking means of apertures and Rastvor- jumps can be formed so symmetrical, so that the retaining clip can be mounted in a first orientation and in a first orientation rotated by 180 degrees orientation. This achieves high installation safety.
- the retaining clip can have spring elements which bear against the motor mount in order to form a spring preload which acts in the radial direction relative to the drive shaft.
- the spring elements can be formed by spring tongues whose fixed foot ends are connected to the retaining clip and whose free ends are supported against wall sections of the motor mount.
- the spring tongues are rigidly connected to the retaining clip.
- the spring tongues are otherwise resilient to bend, so that a resilient mounting of the legs is achieved on the motor mount.
- the spring tongues can be arranged pointing away from one another on opposite sides of the retaining clip and are braced against two opposing wall sections of the motor mount which are oriented at an acute angle to the horizontal and / or to the mounting plug direction.
- the two opposite wall sections oriented at an acute angle to the horizontal and / or to the mounting plug direction can be aligned in a tapered manner in the mounting direction of the mounting clip.
- the spring tongues press against the mutually oriented at an angle wall sections, in other words against a V-shaped or cone-like widening recording of the motor mount.
- the retaining clip is pressed against its joining direction of the V-shaped or cone-like widening receptacle of the motor mount.
- the latching connections hold the retaining clip in its mounting position on the motor mount. The retaining clip is thus vibration damped and play-free, i. fixed without impact in the motor holder.
- the retaining clip may in particular bow-like manner with a central web, which has a bearing point for a rear side of the engine and two opposite, the locking means having legs and each leg two pairs of mounting bracket in the mounting bracket successively arranged spring tongues aufwei sen from the leg wegeruiten and whose free ends are bent against the Montagesteckraum to support against wall sections of the motor mount.
- Each limb can thereby execute a vibration-damped translatory compensation movement running perpendicular to the longitudinal axis of the limb.
- each leg can perform a perpendicular to the thigh plane oriented vibration damped rotational rotational movement or tilting movement.
- the fan housing may have a web section which forms a bearing for a front side of the engine.
- the web section can be carried largely decoupled from the fan housing.
- the web section can have flexurally elastic properties in order to support the front of the engine without play and with vibration damping. Due to the backlash-free and vibration-damped mounting of the web portion, no structure-borne noise caused by the fan wheel motor arrangement is transmitted to the fan housing, or the structure-borne noise is transmitted to the fan housing only to a very subdued extent.
- the web section can be formed by a part of a rear wall of the fan housing delimited by slots.
- the slots may be very narrow, i. have only one or a few millimeters in width, thereby large access openings are avoided in the fan housing through which access openings airborne noise caused by the fan-motor assembly could get into the fan housing.
- the web portion may be formed by two parallel spaced slots. The slots may have lengths and a distance from each other, whereby the delimited web portion has a size and / or contour corresponding to the size and / or contour of the central web of the retaining clip.
- the front engine mount has the same damping properties as the rear engine mount.
- Shape, shape and size of the slots can be chosen such that the front engine mount is connected as a spring vibration damped with the fan housing.
- the rotating fan generates in the fan housing an overpressure, which should relax in the refrigerator, but should not escape unused via other openings from the fan housing.
- the slots do not have to compelling way to be straight, but rather may be formed in a curve.
- a remaining connection region of web section and rear wall of the fan housing can additionally have at least one return.
- the recess can be formed for example by a U-shaped, V-shaped or Z-shaped wall portion of the connecting portion of web portion to fan housing wall.
