[0001] FIXATION SYSTEM FOR MOUNTING A COMPRESSOR IN A REFRIGERATING APPLIANCE, REFRIGERATING APPLIANCE AND METHOD FOR MOUNTING A COMPRESSOR IN A REFRIGERATING APPLIANCE
[0002] FIELD OF THE INVENTION
[0003] The present invention relates to a fixation system for mounting a compressor in a refrigerating appliance, to a refrigerating appliance and to a method for mounting a compressor in a refrigerating appliance.
[0004] BACKGROUND OF THE INVENTION
[0005] For typical fixation solutions by which a compressor can be mounted inside a refrigerating appliance various fixation components must be used such as screws, elastic elements for absorbing vibrations, clip elements or special snap elements and similar.
[0006] The compressor is usually positioned in a lower part of the refrigerating appliance and typically on a back side. Therefore, the compressor is mounted on a special support made of metal or plastic since during its operation it produces vibrations that are transmitted to the neighbouring components. In order to reduce the transmission of vibrations from the compressor to the support and consequently reduce noise, the compressor is typically placed on four elastic supports- bumpers made of rubberized material.
[0007] The compressor can typically be attached to the appliance by screw connections or special snap elements that are attached afterwards and / or can be fastened with bayonet snaps. Such a fixation by screw connections and snap elements can further require additional elements like tools for their attachment and additional assembly time and a use of a bayonet latches can require a specific design of the compressor support for a rotary fit, wherein it may be possible that such a design is generally not compatible with a classic four-point mounting principle. SUMMARY OF THE INVENTION
[0008] It is an object of the invention to improve and simplify the fixation of a compressor in a refrigerating appliance in order to provide a fixation of the compressor which can be achieved with a minimized amount of components and which can be applied and released quickly.
[0009] The object is solved by the subject-matter of the independent claims.
[0010] The present invention pertains to a fixation system for mounting a compressor in a refrigerating appliance according to claim 1, a refrigerating appliance according to claim 8 and a method for mounting a compressor in a refrigerating appliance according to claim 10.
[0011] Preferred embodiments are subject of the dependent claims.
[0012] By the use of a described fixation system according to the invention a flexibility of mounting different types of compressors can be improved. Further, a way of mounting of the compressor without the use of additional tools and exaggerated force can be achieved and a required amount of fasteners can be reduced due to a combination of a static form-fitting joint on one side and a simple sliding latch on the other side of a compressor frame.
[0013] According to the invention the fixation system for mounting a compressor in a refrigerating appliance, comprises a base component having at least one retaining detail into which a front protrusion of a compressor frame can be slid-in along a mounting direction; wherein the base component further comprises assembly positions at which foot regions of the compressor frame can be placed when the front protrusion is slid-in in the retaining detail; wherein the base component further comprises at least one opening from a mounting side which extends along the mounting direction into a body of the base component and extends at least partly underneath the assembly positions; at least one latch having a holding region at a front side of the latch, wherein the latch is configured to be placed inside the opening in the mounting direction and the holding region is configured to hold a pin at a fixed position with regard to a direction perpendicular to the mounting direction; at least one pin which has a grooving at a tip region of the pin, wherein the holding region of the latch can be placed laterally around the grooving of the pin when the latch is pushed in the mounting direction; and at least one elastic foot element which is configured to be placed at the foot region of the compressor frame in a manner partly embedding the foot region into the elastic foot element, wherein the elastic foot element has an inner opening through which the pin can be inserted such that the pin extends through the elastic foot element through the body of the base component into the opening underneath the assembly position where the inserted latch can fixedly hold the pin at its holding region.
[0014] According to the invention the refrigerating appliance comprises a housing; a compressor mounted on a compressor frame with at least one front protrusion and at least one foot region; and a fixation system according to the invention, wherein the compressor is mounted and fixed to the base component and the base component is part of the housing or arranged in the housing.
[0015] According to the invention the method for mounting a compressor in a refrigerating appliance comprises the steps of providing a fixation system according to the invention; the step of placing at least one elastic foot element at the foot region of the compressor frame in a manner partly embedding the foot region into the elastic foot element; the step of pushing the front protrusion of the compressor frame with the compressor frame along a mounting direction into the at least one retaining detail and placing the at least one foot region with the elastic foot element at the corresponding assembly position; the step of inserting the at least one pin with its grooving at the tip region into the at least one inner opening through which the pin is inserted such that the pin extends through the elastic foot element through the body of the base component into the opening underneath the assembly position; and the step of placing the at least one latch into the opening from the mounting side along the mounting direction into the body of the base component and reaching underneath the assembly position and placing the holding region laterally around the grooving of the pin and thereby fixedly holding the pin at its holding region and at a fixed position with regard to a direction perpendicular to the mounting direction. According to a further embodiment of the fixation system the at least one retaining detail is configured to limit a movement of the front protrusion in at least one direction perpendicular to the mounting direction when the front protrusion is slid into the at least one retaining detail.
[0016] According to a further embodiment of the fixation system the elastic foot element has at least partly a cylindrical shape and a radial groove region for partly embedding the compressor frame at a predefined height along a cylindrical axis of the elastic foot element, and wherein the compressor frame has a round opening into which the elastic foot element can be placed with the radial groove region.
[0017] According to a further embodiment of the fixation system the pin comprises a head at an upper end of the pin, which is opposite the tip region of the pin, wherein the head has a greater width than the inner opening of the elastic foot element.
[0018] According to a further embodiment of the fixation system the latch comprises a clip detail, which is configured to engage to a protrusion inside the opening when reaching the mounting position such to block a movement of the latch against the mounting direction.
[0019] According to a further embodiment of the fixation system the fixation system comprises two retaining details and two latches for two openings and two foot regions with two elastic foot elements.
[0020] According to a further embodiment of the fixation system there is a first protrusion inside the opening at which the clip detail can engage when the latch is at an outer position and wherein there is a second protrusion inside the opening at which the clip detail can engage when the latch is at an inner position, wherein the latch can reach the pin in the inner position and cannot reach the pin in the outer position.
[0021] The fixation system can advantageously represent a set of components by which a compressor can be mounted within a base and / or a housing of a refrigerating appliance. The compressor can be placed on a compressor frame which can be arranged at a predefined height above a bottom of a base. The retaining detail can be embodied, for example, as a socket or fitting into which the front protrusion can be pushed in in order to reach a mounting position of the compressor frame. When reaching said mounting position the retaining detail can surround the front protrusion from one, two, three four or five sides and block a movement of the front protrusion in the corresponding direction(s). The front protrusion can be integral with the compressor frame or an attached part of it and located at that end of the compressor frame which is pushed first in the mounting direction when mounting the compressor frame. The retaining detail can be an integral part of the base component, for example made of plastics. The assembly position is a predefined position in the base component which is located at the bottom of the base component such that an end of the compressor frame opposite the front protrusion is placed at. Said end of the compressor frame opposite the front protrusion faces towards the mounting side and therefore the opening for the latch can reach the assembly position with a predefined length of the latch. At the assembly position a hole for the pin can be provided in the bottom of the base component in order to lead the pin to the underneath opening. The directions perpendicular to the mounting direction at which the pin can be held by the latch is, for example, the vertical position perpendicular to the bottom of the base component.
[0022] The pin can have a cylindrical middle section, a pin head on top of it with a radius bigger than the cylindrical middle section and a conical tip region. At a predefined height above the tip region the grooving can be represented by a variation of radius. A holding region of the latch can have a flat opening in the front region of the latch such that the opening has a width smaller than the radius of the pin at its cylindrical middle section but bigger than the radius of the grooving. Therefore, when the holding region is placed in the grooving in mounting direction the pin cannot be moved perpendicular to the mounting direction without contacting the holding region. If the latch is fixed somewhere, for example in the base component, than the pin is held at a fixed position. In other words, the latch can be clamped or held laterally beside the grooving. The wings of the holding region are then arranged laterally beside the pin grooving and prevent a motion of the pin in direction perpendicular to the mounting direction.
[0023] The elastic foot element is configured to absorb the vibrations from the compressor to a desired amount or completely. The elastic foot element can also have a grooving where an edge of a hole in the compressor frame can be embedded into such that the elastic foot element is tightly located in the compressor frame. The inner opening can be embodied as a cylindrical hole through the elastic foot element through which the pin can reach the hole in the base component. On the top of the inner opening a pin head can be placed on the elastic foot element and block a motion of the compressor frame upwards, which means perpendicular to the bottom of the base component and away from the bottom of the base component when the pin is engaged by the latch.
[0024] The elastic foot element can extend through the compressor frame and above it and below it.
[0025] The clip detail of the latch can be integral with the latch, which can be made of plastic. The clip detail can extend longitudinally along the longitudinal extension of the latch, for example in mounting direction and at a middle region of the latch, and be movable in a bending manner perpendicular to the longitudinal direction, for example up and down (towards the bottom of the base). The clip detail can have a starting position at which the clip detail exerts no force to the surrounding and is in an equilibrium position. When the latch is placed to the mounting position on the opening then the protrusion in the opening pushes the clip detail away from the equilibrium position and perpendicular to the mounting direction (longitudinal extend of the latch) such that the clip detail produces a force (and torque) against the protrusion. The protrusion has a detail at which the clip detail can latch in and prevent the motion of the latch against the mounting direction.
[0026] According to a further embodiment of the refrigerating appliance the refrigerating appliance comprises a cover for the housing or for the base component by which the mounting side can be closed and the latch covered.
[0027] According to a further embodiment of the method the clip detail of the latch is engaged to a protrusion inside the opening when the mounting position is reached and wherein the clip detail is released from the protrusion when removing the latch from the pin and from the opening.
[0028] According to a further embodiment of the method the pin is placed with its head on top of the inner opening of the elastic foot element in order to hold the elastic foot element and the compressor frame at a fixed vertical position perpendicular to the mounting direction. The base component can preferably be made of a thermoplastic material.
[0029] The latch can be embodied as a forked slider (pre-applied in the base component).
[0030] The pin can comprise steel and the elastic foot element can comprise rubber.
[0031] Instead of the refrigerating appliance all features can also be valid for a cooling device in general. The advantages of the method can also apply to the refrigerating appliance and / or to the fixation system or vice versa.

[0038] DETAILED DESCRIPTION OF THE INVENTION
[0039] Although specific embodiments have been illustrated and described herein, it will be appreciated by those of ordinary skill in the art that a variety of alternate and / or equivalent implementations may be substituted for the specific embodiments shown and described without departing from the scope of the present invention. Generally, this application is intended to cover any adaptations or variations of the specific embodiments discussed herein.
[0040] Fig. 1 shows a schematic view of a base component with latches of a fixation system according to an embodiment of the invention.
[0041] The fixation system 100 for mounting a compressor in a refrigerating appliance comprises a base component B, for example of plastics. The base component B can have two retaining details RD which can be integral with the base component B and can each form a slide-in housing. Fig. 1 shows an embodiment of retaining details RD which block the motion of a front protrusion of the compressor frame (not shown) in mounting direction D, upwards and downwards and towards the next outer walls of the base component. The base component B further comprises two openings OA from a mounting side MS which extends along the mounting direction D into a body of the base component B and under its bottom and extends at least partly underneath the assembly positions AP for the foot regions of the compressor frame (not shown).
[0042] Two latches L are shown which can be slid into the corresponding openings OA with the holding region HR for the pin at its front such that the holding region HR at a latch L is pushed inside the opening OA first. The holding regions HR reach at mounting position a location underneath the assembly position AP. Fig. 2 shows a schematic view of a compressor when mounted according to an embodiment of the method of the invention with a fixation system in a refrigerating appliance according to an embodiment of the invention.
[0043] A refrigerating appliance 10 comprises a housing (not shown) and a compressor 1 mounted on a compressor frame CR with at least one front protrusion FP (hidden behind the compressor and not shown in Fig. 2) and in the embodiment of Fig. 2 two foot regions FR and a fixation system 100 with its components for fixation. The compressor 1 is mounted and fixed to the base component B.
[0044] The assembly positions AP on which the foot regions FR of the compressor frame CR can be placed when the front protrusion FP is slid-in in the retaining detail RD can be at a predefined distance from the mounting side MS and the foot regions FR can therefore represent that part of the compressor frame CR which is the closest to the mounting side MS when arranged at the mounting position. The pin P can be inserted before the latch L is pushed to the mounting position. The latches L are placed inside the opening OA in the mounting direction D and the holding region is configured to hold a pin P at a fixed position with regard to a direction perpendicular (vertical) to the mounting direction D.
[0045] The elastic foot elements FE are each placed at the foot region FR of the compressor frame CR in a manner partly embedding the foot region FR into the elastic foot element FE.
[0046] The pin P can be inserted into the elastic foot element FE such that the pin P extends through the elastic foot element FE underneath the assembly position AP where the inserted latch L can fixedly hold the pin P at its holding region.
[0047] By executing the method a placing S1 of the elastic foot elements FE at the foot region FR can be done in a manner partly embedding the foot region FR into the elastic foot element FE. Further, a pushing of the front protrusion FP along a mounting direction D into the retaining detail RD and placing the foot regions FR with the elastic foot element FE at the corresponding assembly position AP can be performed. Further, inserting S2 the pins P with its grooving at the tip region into the inner opening through which the pin P is inserted such that the pin P extends through the elastic foot element FE through the body of the base component B into the opening OA underneath the assembly position AP can be performed. Further, placing S3 the at least one latch L into the opening OA from the mounting side MS along the mounting direction D into the body of the base component B and reaching underneath the assembly position AP and placing the holding region laterally around the grooving of the pin P and thereby fixedly holding the pin P at its holding region and at a fixed position with regard to a direction perpendicular to the mounting direction D can be performed.
[0048] Fig. 3 shows a schematic cross sectional view of a fixation system with a compressor mounted in a refrigerating appliance according to an embodiment of the invention.
[0049] In Fig, 3 the assembled position is shown and compressor frame CR, the pins P, the foot regions FR, the foot elements FE and the latches L are at the mounting position. In the front part of Fig. 3 a cross sectional view along the mounting direction is shown.
[0050] The elastic foot element FE embeds the compressor frame CR such that the edge of a hole of the compressor frame CR at the foot region FR is embedded into the elastic foot element FE. The elastic foot element FE has at least partly a cylindrical shape and a radial groove region where the radius of its cylindrical form is smaller than at the top region of the elastic foot element (above the frame CR) and smaller than at the foot part of the elastic foot element FE (below the frame CR and on the bottom of the base B, here the elastic foot element FE has the biggest radius) for partly embedding the compressor frame CR at a predefined height along a cylindrical axis of the elastic foot element FE. The elastic foot element FE has an inner opening FE- A through which the pin P can be inserted such that the pin P extends through the elastic foot element FE through the body of the base component B into the opening OA underneath the assembly position AP where the inserted latch L can fixedly hold the pin P at its holding region HR. The pin P comprises a head P-H at an upper end of the pin P, which is opposite the tip region P- T of the pin P, wherein the head P-H has a greater width than the inner opening FE of the elastic foot element.
[0051] When the latch L is inserted completely the holding region HR engages or holds the grooving P- G in a vertically fixed position. Further, in the inserted position of the latch L the clip detail CD of the latch L is engaged to a protrusion PR inside the opening OA when the mounting position is reached and wherein the clip detail CD is released from the protrusion PR when removing the latch L from the pin P and from the opening OA.
[0052] According to the embodiment of Fig. 3 there is a first protrusion PR1 inside the opening OA at which the clip detail CD can engage when the latch L is at an outer position and wherein there is a second protrusion PR2 inside the opening OA at which the clip detail CD can engage when the latch L is at an inner position, wherein the latch L can reach the pin P in the inner position and cannot reach the pin P in the outer position. In this regard Fig. 3 shows a cut along a middle section of the latch L and through the clip detail CD. The second protrusion PR2 can have an inclined surface with respect to the vertical direction (perpendicular to the mounting direction) and the clip detail CD can be pulled over this second protrusion PR2 with enough force. The first protrusion PR1 can have a vertical surface with respect to the mounting direction and the clip detail CD can be fixedly stopped there from pulling out of the opening OA.
[0053] The pin P is placed with its head P-H on top of the inner opening FE-A of the elastic foot element FE in order to hold the elastic foot element FE and the compressor frame CR at a fixed vertical position perpendicular to the mounting direction. All latches L and corresponding plurality of components can be embodied in a correspondingly equal manner.
[0054] Fig. 4 shows schematic view of a latch with a pin of a fixation system according to an embodiment of the invention.
[0055] The pin P can have a cylindrical form with a tip and a grooving P-G next to a tip. The pin P further comprises a head P-H with a radius bigger than at the middle cylindrical region and which head is located at an upper end of the pin P, which is opposite the tip region of the pin P.
[0056] In other words, the pin P can have a cylindrical middle section, a pin head P-H on top of it with a radius bigger than the cylindrical middle section and a conical tip region. At a predefined height above the tip region the grooving P-G can be represented by a variation of radius. A holding region HR of the latch L can have a flat opening in the front region of the latch L such that the opening has a width smaller than the radius of the pin at its cylindrical middle section but bigger than the radius of the grooving P-G. Also the clip detail CD in a middle region of the latch L is shown. Therefore, when the holding region HR is placed in the grooving in mounting direction the pin P cannot be moved perpendicular to the mounting direction without contacting the holding region HR. If the latch L is fixed somewhere, for example in the base component B, then the pin is held at a fixed position. In other words, the latch L can be clamped (or held in another manner) laterally beside the grooving P-G. The wings of the holding region HR are then arranged laterally beside the pin grooving P-G and prevent a motion of the pin in direction perpendicular to the mounting direction.
[0057] In Fig. 4 the pin P is shown in the final mounting position and the latch L has to be pushed towards it. The remaining components of the fixation system are omitted for clarity reasons.
[0058] In the foregoing detailed description, various features are grouped together in one or more ex- amples or examples with the purpose of streamlining the disclosure. It is to be understood that the above description is intended to be illustrative, and not restrictive. It is intended to cover all alternatives, modifications and equivalents.
