A rotating lid 15 is inserted in the centre bore of cover 7.Lid 15 has a hand operated button 16 that has the circle edge, flat of roughening in its outside, and it can make a user be easy to rotatable cover 15.

Fig. 6 is illustrated in the front area and cover 7 of the basic element of character 3 in the state of being separated from each other with an oblique birds-eye perspective.Can see the locking hook 17 interior side-prominent, that hook the edge of cover 7 at rotating lid 15, these locking hooks will cover 15 and remain on rotationally in the hole of cover 7.In lid 15 center protrusion a bayonet couplings 18.Can be inserted in the bayonet couplings 6 of complementation of the basic element of character 3 at lid 15 the first turned position upper latch notch formula connector 18, and turn to by covering 15 that this lid can be locked on the basic element of character 3 on the second place.

Fig. 5,6 all represents to cover 15 in its locking orientation.Two holes 19 at this orientation middle cover 15 are aimed at the screw post 5 of the basic element of character.Can accomplish thus, the fully pre-assembling and the basic element of character is installed on the top board in interior space of chiller before it packs chiller into of first housing parts 1 by import screw in these posts 5 by these holes 19, and cover 7 is pulled down again.

In the Background Region of cover 7, be configured with a large-area breach 20.Insert some plates 21 in the assembled state of cover in this breach 20, these plates are molded on the basic element of character 3 vertically downward highlightedly.These plates 21 only are connected with the basic element of character 3 with its upper end; Their bottom is not connected, and the basic element of character 3 can be with these plates 21 by simple die pressure injection moulding thus.

These plates 21 do not fill up breach 20 on its whole width and height.Therefore when the basic element of character 3 and when covering 7 joints, obtain one at the back side of first housing parts 1 along the edge of this breach and have the roughly gap of C shape cross section, can insert in this gap and can be in certain limit move on vertically at it corresponding to second housing parts 2 of this cross section moulding.

Fig. 1 represents second housing parts 2, it have can be directly at the leading edge of locating previously in the C shape gap 22 that limits by breach 20 and plate 21.Second housing parts 2 has some L shaped sidewalls 24, and the outward flange of these sidewalls is all by moulding, so as with the horizontal zone form fit above it abut against on the top board and with the vertical area form fit of its back abut against on the rear wall in the interior space of refrigerator.Extend the screw post 26 of inclined orientation from a horizontal coverboard 25 that is connected with these sidewalls 24, they are used to make housing parts 2 to be fixed on the top board of inner pressurd vessel.Housing parts 2 forwardly constitutes a hollow passageway of flat, rectangular cross section in the zone, and this passage can be inserted in the gap 22 of first housing parts with the variable degree of depth.Housing parts 2 is expansion downwards in Background Region, has the ventilation unit that motor 27 reaches the impeller 28 that is driven by motor 27 so that can hold one.When this ventilation unit work, it drives an air stream, air is sucked and blows out by second slot 29 adjacent with rear wall interior space housing parts 2 from first housing parts 1, so that produce such air stream along the rear wall that passes through evaporator cools in interior space.

Describe the internal structure of second housing parts in detail by Fig. 7 and 8.Fig. 7 represents the part exploded view of second housing parts of seeing from oblique back upper place 2 and the part that is mounted in it.On the inwall of housing parts 2, form two parallel retention tabs 30.They are set for and remain on the installation folder of representing enlargedly among Fig. 8 31.Should have four opposed in couples, as to pass through some roundings sides 32 to 35 connected to one another, angle by the installation folder 31 of plastics moulding integratedly.Respectively form a locking wedge 36 on the flat outside of

side

33,35, when folder 31 being installed being directed between these retention tabs 30, each locking wedge is coupled among of some windows 37 and makes thus and folder 31 is installed is locked on the housing parts 2.

In the

side

32,34 of the length that opposes mutually, respectively be configured with a breach that is open upwards 38.The entrance area of breach 38 is limited by two arms 39 that extend from the top down, and the remainder of these arms and

side

32,34 only is connected by the narrow contact pin on the height of edge 40 on top and so can flexibly be offset.In the lower area of breach 38, be configured with a semicircular circular arc 41.The diameter quilt of this circular arc is sizing in this wise, but so that its form fit ground holds the shaft attachment (Wellenansatz) that is pressed into the motor 27 that folder 31 is installed by the top.When motor was pressed in the installation folder 31, in case shaft attachment passes through arm 39, the arm 39 of then deflection turned back to the release position shown in Fig. 8, and stoped motor 27 to make progress from folder 31 is installed thus.The axle of motor 27 can irrespectively be fixed reliably with the accurate shell dimension of motor in this way.Only be the diameter of the shaft attachment of motor 27 must be in certain tolerance the size of adaptive breach 38.

In order to prevent that these arms 39 from also can make motor deviate from from folder 31 is installed to the direction upper deflecting of the axle of motor 27 thus, the top edge 40 of

side

32,34 is strengthened by some outstanding on the direction of motor reel ribs.On

side

32,34, also be configured with some corresponding ribs 23 below the breach 38.

In order to prevent that motor 27 from rotating around the axis of oneself, folder 31 to be installed to be provided with two flexible arms 42, they protrude upward from the

side

33,35 parallel with the axle of motor 27.Back on the top of arm 42 broadenings respectively snaps in a rubber ring 43.These rubber rings 43 are annulars in depressurization phase.Dwell portion quilt on the top of arm 42 is sizing in this wise, so that rubber ring 43 keeps off in the release position by its, but when rubber ring was pressed on the wall 42 flatly, rubber ring can freely be deviate from and non-resistance ground upwards is drawn out of and can be replaced by the ring with another wall thickness by dwell portion.

When motor 27 was placed in the installation folder 31, the surface that is facing with each other of rubber ring 43 contacted with the sidewall of the side direction of the stator lasmination 44 of motor.Because the elasticity of these arms and rubber ring 43 can make motor be fixed on reliably in the installing holder 31 without difficulty, these motor are on the width of its stator lasmination and some millimeters difference can be arranged.Corresponding replacing by rubber ring 43 can obtain the bigger tolerance on the size.

The running cost that motor 27 is assembled in the housing parts 2 is minimum: only motor is inserted in the breach 38 that folder 31 is installed and will install and press from both sides 31 and lock in the retention tab 30 of housing parts 2 and get final product.

When ventilation unit installs, also a baffle plate 45 to be hooked on the

locking hook

46,47 of housing parts 2.Baffle plate 45 has circular central window 48, and the diameter of this window is corresponding to the diameter of impeller 28.This baffle plate will stop the air that is blown on the chiller rear wall by ventilation unit to pass through the efficient that impellers 28 flow to the place ahead laterally again and improve ventilation unit thus in housing parts 2 inside.

Two sectional views and their installations below the top board 49 of the inner pressurd vessel of chiller of Fig. 2 and two

housing parts

1,2 of 3 expressions.Fig. 2 represents a configuration that draws back each other, and wherein the front area of second housing parts 2 only has seldom part enter in first housing parts 1.Top board 49 has a sloping portion 50 that has stage 51 in the zone near door.The position of first housing parts 1 is fixed with contacting of stage 51 by covering 7 block 14.The top edge 52 towards sloping portion 50 of cover 7 is parallel to sloping portion 50, and has a ventilation gap 53 between the two.

Fig. 3 represents the configuration that moves towards one another of housing parts, and wherein second housing parts 2 in depth is engaged in first housing parts 1.Here block 14 separates with the stage 51 of top board 49, forms very large-area air thus and enters the gap.Because two

housing parts

1,2 can be infinitely, telescopically move each other, so the cross section of ventilation gap can adapt to needs neatly.

But

housing parts

1,2 scalable ambulant specific uses are: these housing parts move in difference far and nearly can need not to be used for adaptedly being installed in the chiller with spatial depth in the difference in the near configuration.
