Abstract

An air-conditioning cabinet can have an outer boiler, an inner chamber with an inner chamber height, a cover, a bottom where the cover and bottom are separated by a distance that defines the inner chamber height, an inner boiler having a foot movably coupled to the inner boiler, where the inner boiler is arranged in the outer boiler, where the inner boiler height is less than the inner chamber height and where the foot is movably coupled to the inner boiler in such a manner that the inner boiler height is variable. Also, moving a position of the foot on the inner boiler can arrange the inner boiler such that the inner boiler is supported on the cover of the outer boiler and the foot is supported on the bottom of the outer boiler, and the foot can be fixed in the position.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to German Patent Application No. 10 2017 116 527.4, filed Jul. 21, 2017 which is incorporated by reference in its entirety.

BACKGROUND

The application relates to a method for the precisely fitting positioning of an inner boiler in the outer boiler of an air-conditioning cabinet and air-conditioning cabinet.

Air conditioning cabinets with an inner boiler, an outer boiler and a heating and/or cooling device arranged at least in sections between the outer boiler and the inner boiler have been known for many years, for example, from DE 33 29 855 A1 or DE 37 27 298 A1. In spite of this product having been known for a long time, a weak point in its manufacture, however, is still the arrangement of the inner boiler in or on the outer boiler, which arrangement should not only be stable but in addition should also fit as precisely well as possible in particular on the cover-side contact line of the inner boiler walls to the outer boiler in spite of occurring manufacturing tolerances. Even if two co-workers are involved in this manufacturing step, its processing safety and reproducibility remain problematic.

SUMMARY

The application is directed to structures and a method for the precisely fitting positioning of an inner boiler in the outer boiler of an air-conditioning cabinet and an air-conditioning cabinet with an inner boiler which can be positioned with a precise fitting. Structures and methods for such precisely fitting positioning of an inner boiler in the outer boiler of an air-conditioning cabinet and an air-conditioning cabinet with an inner boiler which can be positioned with a precise fitting are disclosed herein. Advantageous embodiments and further developments are also disclosed.

The method according to the present disclosure for the precisely fitting positioning of an inner boiler in the outer boiler of an air-conditioning cabinet can comprise the following steps:

Making available an outer boiler with a cover and a bottom located opposite the cover,

Making available at least one component of an inner boiler, and

Positioning the at least one component of the inner boiler between the cover and the bottom in the outer boiler.

In one arrangement such a cabinet can be arranged such that:

at least one component of the inner boiler is made available which has a lesser height than the height of the inner chamber of the outer boiler, which height is given by the distance between the cover and the bottom of the outer boiler, and on which component at least one foot is movably arranged in such a manner that the height of the at least one component of the inner boiler, and which includes the at least one foot which is movably arranged on it, is variable,

a precisely fitting positioning is brought about by a changing of the position of the at least one foot on the component arranged in the inner boiler, in which the component of the inner boiler is supported on the cover of the outer boiler and the at least one foot is supported on the bottom of the outer boiler, and

the foot is fixed in the position in which it brings about the precisely fitting positioning.

Therefore, the previously used attempt to adapt the component of the inner boiler as exactly as possible to the corresponding dimension of the outer boiler is given up and instead of it a “too small” component of the inner boiler is used which is not brought in a precisely fitting contact with the cover until by the adjusting of the feet which are movably arranged on the component of the inner boiler. This not only makes it possible to compensate the particular tolerances of the outer boiler but also proves to be clearly simpler as regards the carrying out of this work step since the introduction of a component of the inner boiler, which component is dimensioned with a precise fitting to the outer boiler, is often difficult.

It is mentioned here that the concept “air-conditioning cabinet” is to be broadly understood. An air conditioning cabinet denotes here every cabinet-like device in whose inner chamber a temperature can be adjusted which deviates from the environmental conditions. To this end, air-conditioning cabinets as a rule comprise a heating and/or cooling device which can be arranged at least in sections—therefore, for example, with a cooling hose or heating hose—in the inner chamber of the outer boiler, preferably between the outer boiler and the inner boiler. At least the inner chamber of the inner boiler is usually accessible by doors or flaps; the direction from which it is accessible is given by a loading direction.

Accordingly, in particular making the outer boiler available can take place in such a manner that the outer boiler already built into the later air-conditioning cabinet is made available completely with the later air-conditioning cabinet and the heating and/or cooling device; however the outer boiler can also be made available as an individual component preconfigured with more or less additional attached parts.

An outer boiler typically comprises at least two side walls, a bottom and a cover as well as optionally also a back wall.

The inner boiler can be formed in one piece, which then has the result that the sole component of the inner boiler is the inner boiler itself. However, it is typically built up from several individual parts or components, for example, of side walls between which an inner back wall or a bottom is then held. However, it can also comprise only side walls.

A preferred embodiment of the method provides that the precisely fitting positioning takes place by a shifting of the position of the foot in a plane parallel to the bottom of the outer boiler, wherein it is especially preferred that the shifting of the position of the foot takes place in a direction parallel to the component of the inner boiler on which the foot is arranged. This can be in particular the direction of a side wall of the inner boiler running parallel to the direction of access if this wall comprises the foot or the feet. These measures are advantageous because the “working direction” in which force must be exerted in order to achieve the precise fitting in of the component of the inner boiler is the access direction, which simplifies the exertion of force. For example, a shifting of the feet in an oblong hole or slot which runs obliquely to the bottom of the outer boiler and in which a bolt is guided which is supported on the corresponding component, in particular on a side wall of the inner boiler can bring about the precisely fitting arrangement by pressure in the access or loading direction of the air-conditioning cabinet while, for example, in the case of screw feet an impractical fingering would be necessary in order to tighten screws located close to the bottom.

The air-conditioning cabinet according to the present application can comprise an outer boiler with a cover and a bottom whose distance defines the height of an inner chamber of the outer boiler, comprises an inner boiler arranged in the outer boiler and comprises a heating and/or cooling device arranged at least in sections between the outer boiler and the inner boiler. Of course, it can additionally comprise doors, an outer skin, a frame or feet, which is often the case in air-conditioning cabinets.

In one embodiment of the application, at least one component of the inner boiler—for example, a side wall—has a lesser height than the height of the inner chamber of the outer boiler, which height is given by the distance between the cover and the bottom of the outer boiler, and on which component at least one foot is movably arranged in such a manner that the height of the at least one component, which was made available, of the inner boiler, and which includes the at least one foot which is movably arranged on it, is variable, so that a changing of the position of the at least one foot on the component, arranged in the outer boiler, of the inner boiler can bring about a precisely fitting positioning in which the component of the inner boiler is supported on the cover of the outer boiler and the at least one foot is supported on the bottom of the outer boiler and that the at least one foot can be fixed with a fixing means in this position. The advantage of this special design is in particular the fact that the arrangement of the inner boiler adapted to the outer boiler can be achieved by simple work steps with very good preciseness.

Such an air-conditioning cabinet is preferred if the at least one foot is arranged on the component of the inner boiler in such a manner that the height of the at least one available component of the inner boiler with the at least one foot arranged on it can be varied by a shifting parallel to the plane defined by the bottom of the outer boiler, wherein it is especially preferred if the at least one foot is arranged on the component of the inner boiler in such a manner that the height of the at least one available component of the inner boiler with the at least one foot arranged on it can be varied by a shifting parallel to the component of the inner boiler on which the foot is arranged. This applies in particular for a shifting parallel to the side wall of the inner boiler as the relevant component of the inner boiler here in the access direction or loading direction of the air-conditioning cabinet, which makes possible an especially simple and direct action.

In a concrete manner, such an arrangement of the foot on the component of the inner boiler can be brought about in that the component of the inner boiler comprises at least one bolt and that the at least one foot comprises an oblong hole in which the bolt is guided, wherein the distance of the oblong hole from the end of the foot facing the bottom of the outer boiler varies. Upon a shifting of the foot supported on the bottom of the outer boiler, the component of the inner boiler is then pressed upward and is therefore adapted to the extension of the particular outer boiler.

It is especially preferred if the oblong hole runs at an angle of about 45° relative to the bottom of the outer boiler.

Furthermore, it is advantageous if the foot has a surface for introducing a shifting force because it facilitates introducing an appropriate force during the assembly.

BRIEF DESCRIPTION OF THE DRAWINGS

The present application is explained in detail in the following using figures showing an exemplary embodiment. In the figures:

FIG. 1a: shows an air-conditioning cabinet with open doors,

FIG. 1b: shows a sectional enlargement from figure la which shows the positioning of a component of the inner boiler in the outer boiler,

FIG. 1c: shows an even greater sectional enlargement from figure la which shows in detail the arrangement of a foot on the inner boiler and which supports the inner boiler,

FIG. 2a: shows a first view of a foot, and

FIG. 2b: shows a second view of the foot from FIG. 2a.

FIG. 1a shows an air-conditioning cabinet 1 with open doors 3 so that the view into the interior of the air-conditioning cabinet is free. It can be recognized that the air-conditioning cabinet 1 comprises an outer boiler 10 in which an inner boiler 2 composed by components 21 is arranged. In this exemplary embodiment of an air-conditioning cabinet 1, shelfs 4 are arranged on the inner boiler 3. The heating and/or cooling device of the air-conditioning cabinet 1 cannot be recognized in the view of figure la because it is covered by the inner boiler 3 and its components 21.

FIG. 1b shows a section A of the view into the interior of the air-conditioning cabinet 1, more precisely into its front right, lower corner. A section of the outer boiler 10 and of its bottom line 11 and the transitional area 12 to its right side wall 13 which is, however, largely covered by a component 21 of the inner boiler 2, here the right side wall of the inner boiler 2, can be recognized.

The component 21 of the inner boiler 2 does not stand directly on the bottom 11 of the outer boiler 10 but rather is supported thereby several feet 30, which directly and necessarily results in that the component 21 of the inner boiler 2 has a lesser height than the height of the inner chamber of the outer boiler 10 given by the distance between the cover, which cannot be recognized in FIG. 1, and the bottom 11 of the outer boiler 10.

The specific construction of the foot will now be explained in detail using the FIGS. 2a and 2b.

As can be readily recognized in the FIGS. 2a and 2b, the foot 30 has an approximately U-shaped cross section with a back 31 and two side walls 32, 33 standing vertically to the surface of the back 31 which are secured against bending with reinforcements 34. An oblong hole 35 running obliquely from the upper right to the lower left is arranged in the back 31 of the foot 30.

If an installed foot 30 is considered in detail in its installed position, which can be gathered especially well referring again to the enlarged view according to the FIG. 1c, it can be recognized that it is movably connected to the component 21 of the inner boiler 2. This is realized in that a bolt 23 which is provided at least in sections with a thread cut on it is welded to a connection section 22 of the side wall forming the component 21 of the inner boiler 2, which bolt is guided in the oblong hole 35 and can be fixed with a fixing means 24 constructed here as a self-securing screw so that the back 31 of the foot 30 rests on the component 21 of the inner boiler 2, more precisely of its connection section 22 and runs substantially parallel to the component 21 of the inner boiler 2.

If the foot 30 is now pressed on one of its side walls 32, 33, which can serve as surfaces for introducing a shifting force parallel to the bottom 11 of the outer boiler 10 and to the component 21 of the inner boiler 2 in the direction of the rear wall of the air-conditioning cabinet 1, then the bolt 23 moves upward in the obliquely running oblong hole 35 and therefore forces a precisely fitting resting of the component 21 of the inner boiler 2 in the area of the not-shown cover of the outer boiler 10 because the total height of the system of component 21 of the inner boiler 2 with foot 30 arranged on it becomes greater. Therefore, a component 21 of the inner boiler 2, which component can be introduced without problems into the outer boiler 10 on account of its lower height, can be readily prepositioned there and be readily and precisely fit into the outer boiler 10 by the introduction of pressure on the easily accessible side walls 32, 33 of the foot 30 from the access direction, which entails a significant simplification of this step in the manufacturing process.
