In order to interfere the decoupling in the effective vibrotechnique between fan 149 and refrigeration locular wall 107, in each holding Damping disk(-isc) 109 is respectively disposed on the corresponding jointing 163 of arm 159, wherein referring to root in terms of the configuration of damping disk(-isc) 109 According to Fig. 2A, 2B and 3 embodiment.Herein, each damping disk(-isc) 109 is especially arranged in corresponding fixed dome portion 161 and corresponding It is particularly effective in vibrotechnique between fan 149 and refrigeration locular wall 107 to ensure between jointing 163 Decoupling.

Fig. 5 is shown in section view the connection between fan 149 and the refrigeration locular wall 107 of refrigerating appliance 100.

Refrigerating appliance 100 has fan 149, which has for colder air to be supplied to refrigeration from air duct Fan unit 151 in the refrigerating chamber 103 of utensil 100.The fan unit 151 of fan 149 and the blower tray 153 of fan 149 Connection, wherein blower tray 153 has multiple retaining arms 159, three of them outstanding retaining arm 159, to make fan 149 and refrigeration The refrigeration locular wall 107 of utensil 100 connects.Shown in the section being shown in FIG. 5 a retaining arm in the retaining arm 159 and Jointing 163, wherein jointing 163 is connect with the fixation dome portion 161 of refrigeration locular wall 107.Herein, in retaining arm It is disposed with damping disk(-isc) 109 between 159 jointing 163 and the fixation dome portion 161 for refrigerating locular wall 107, to make fan 149 It is decoupled in vibrotechnique with refrigeration locular wall 107.

Damping disk(-isc) 109 has the external disk 111 connected by disk jointing 115 and inner disc 113.In the outside of external disk 111 117 and inner disc 113 inner face 119 on be disposed with the protrusion 121 being not shown in Figure 5.Protrusion 121 reduces in external disk 111 Contact surface between refrigeration locular wall 107.

The first diameter 143 of disk jointing 115 is less than the second diameter 145 of external disk 111 and first diameter 143 is less than The third diameter 147 of inner disc 113, so that being formed in the circular notch in damping disk(-isc) 109 between external disk 111 and inner disc 113 165.The jointing 163 of the retaining arm 159 of fan 149 is scarfed in notch 165, wherein at least area of jointing 163 Segmentation surround damping disk(-isc) 109 disk jointing 115, so as to make damping disk(-isc) 109 and the especially shape of retaining arm 159 it is sealed and/ Or force closure connect.

Damping disk(-isc) 109 has central through-Penetration portion 123, and fixed dome portion 161 passes through the center through-Penetration portion, so as to by damping disk(-isc) 109 are located in fixed dome portion 161.Herein, fixed dome portion 161 sticks on the inner wall 125 of central through-Penetration portion 123. Herein, fixed dome portion 161 has fixed salient 167, which sticks on the inner face 119 of inner disc 113, with Just damping disk(-isc) 109 is fixed, especially shape is sealed and/or force closure be fixed on jointing 163 and fixed dome portion 161 it Between.

The through-Penetration portion 131 that damping disk(-isc) 109 also extends with multiple circumferential directions 129 along damping disk(-isc) 109, the through-Penetration portion It is at least arranged around 133 ground of central axes of damping disk(-isc) 109 to range selector, wherein through-Penetration portion 131 passes through through-Penetration portion partition respectively 141 are separated from each other.Through-Penetration portion 131 can be realized the effective compensation of the torque generated by fan 149.

Therefore, damping disk(-isc) 109 is advantageously configured to for being decoupled fan 149 and refrigeration locular wall 107 in vibrotechnique, To make not to be directly delivered to refrigerating appliance 100 by the different frequency that the fan motor of fan 149 generates in different rotating speeds It refrigerates on locular wall 107 and component thus adjacent with the refrigeration locular wall.Therefore, the freedom being lifted in the configuration of other attachmentes Degree, because need not particularly consider especially strong resistance to vibration again herein.Furthermore, it is possible to pass through the material of damping disk(-isc) 109, especially Be Shore Hardness specific selection or through-Penetration portion 131 size extension or shortening or protrusion 121 or other protrusion The variation of geometry is advantageously adapted for the vibration damping degree of other radial fan 149.

All features illustrated and shown in conjunction with each embodiment of the invention can be with different combination settings in root According in subject of the present invention, to realize their favourable effect simultaneously.

Protection scope of the present invention is illustrated by claim and not by illustrating in specification or shown in the accompanying drawings Feature limitation.
