Abstract

The invention relates to a refrigeration device with a fixing system for a horizontal evaporator (2), located in at least one cold chamber (1). The fixing system fundamentally comprises retaining elements (7), by means of which the evaporator is rigidly mounted and thus rendered immovable, such that noises and vibration which occur with other, conventional fixing systems, can be avoided. The retaining elements (7) serve not only as fixing means of the evaporator, but also as guides for the compartments (14) of the refrigeration device and as stops to limit the displacement of the compartments (14) whilst the same are being withdrawn.

Description

Refrigerating plant

The present invention relates to comprise the refrigerating plant of horizontal evaporator, these evaporimeters are arranged in the freezing tank of refrigerating plant or in the refrigerating chamber.

These evaporimeters are installed on the sidewall paneling of each refrigerating chamber.

Based on this prerequisite, task of the present invention is to improve the current fixed system of horizontal evaporator of the refrigerating plant of refrigerating plant.

For this reason, the present invention is made of the keeper of evaporimeter in principle, and described keeper is used for fixing fully reliably and can not moves.

Horizontal evaporator under normal circumstances is fixed on the sidewall paneling of refrigerating plant refrigerating chamber by a plurality of parts, and wherein these parts are complicated especially.

Fix evaporimeter by these parts and can't fully guarantee the steel wire or the bonding jumper of whole pipe and each evaporimeter are all fastened, thereby the undesirable people's of disturbing noise and vibration have sometimes occurred.

In order to finish task of the present invention and to avoid the described shortcoming of leading portion, the present invention proposes a kind of refrigerating plant, and it comprises a fixed system, so that fix the horizontal evaporator in the refrigerating chamber that is positioned at refrigerating plant or the freezing tank reliably.

The characteristics of this system are that it comprises the very simple keeper of geometry, and these keepers are finished three kinds of major functions:

The firstth, fixed function, for this reason, corresponding keeper is loaded in the side mounting of groove, in evaporimeter pipe of part embedding of keeper.In case realize this chimericly, the opposite side of keeper has had lever function, is embedded under the steel wire of corresponding evaporimeter up to the center of keeper gudgeon and projection.

To the guiding energy of refrigerating plant drawer, be on the preceding left end and preceding right-hand member of evaporimeter if keeper has been installed on each end, then other two parts can be fixed on back left end and back right-hand member, so that provide four supporting-points for the drawer of refrigerating plant like this.Like this, drawer just is bearing on four points, and these corresponding components play the guide when extracting out and pushing simultaneously.

The backstop function of refrigerating plant drawer, the height of keeper is enough to finish the Drawer obstructing function, wherein the shape that all is necessary of these drawers.

In addition, this new system has compared following major advantage with legacy system, that is:

-reduced the quantity of the different parts of each refrigerating plant;

-reduced material cost and processing cost;

-evaporimeter fixing because of the lever function of keeper very firm, thereby avoided the undesirable noise and the vibration that when using other conventional attachment system, produce.In addition, owing to use this novel keeper, obtained evaporimeter firm especially and rigidity and fixed;

The thermal deformation of-groove is proved to be bigger and is simple;

-owing to removed the upper support guiding mechanism of evaporimeter, thereby won volume.

Below listed several accompanying drawings and be used for understanding better to explanation of the present invention, these accompanying drawings are indispensable parts of this specification and task of the present invention have been described.

Fig. 1 is the refrigerating chamber of refrigerating plant or the three-dimensional view of freezing tank, and portion has a horizontal evaporator at least within it, and this evaporimeter is fixed on the sidewall paneling by a fixed system, and this is a core of the present invention.

Fig. 2 is the front view of freezing tank, shows the keeper that constitutes fixed system at this, and these keepers are as supporting and guiding mechanism that conventional drawer in the groove is set.

Fig. 3 is a longitudinal cross-section view, wherein mainly shows evaporimeter and blocks projection at fixture spare or keeper, also shows the drawer of a lower process, and when extracting out, this lower process is as backstop.

Fig. 4 is the perspective view of keeper.

Below the embodiment of the invention is described with numbering used in the accompanying drawing.

Refrigerating plant comprises a groove 1, and portion is provided with a horizontal evaporator 2 at least within it, and this evaporimeter is placed on bearing or the supporting member 3 in principle, and bearing or supporting member link to each other with the sidewall paneling 4 of the groove 1 of refrigerating plant securely.

Evaporimeter 2 comprises a structure that is made of pipe 5 and parallel steel wire or bar 6, and steel wire or bar are connected with pipe 5, thereby evaporimeter 2 is placed on the bearing 3 by the part of pipe 5, and bearing is concordant with the edge of evaporimeter 2.

By maintaining part or the keeper 7 aimed at some bearings 3 of groove 1 sidewall paneling 4 on evaporimeter 2, realized the fixing of evaporimeter 2.For this reason, be provided with mounting or dimple 8 on the bearing 3 and on sidewall paneling 4, keeper 7 enters in this dimple by the one end and forms backstop.

Thereby, on the stuck position of each keeper 7, keeper plays leverage, thereby makes parts 7 form backstop by each dimple 8 upper surfaces 9 ground that the one end leans against groove 1 sidewall paneling 4, and keeper 7 is pressed to the pipe 5 of evaporimeter 2 simultaneously downwards, and evaporimeter 5 is placed on each bearing 3.

The restraint location of keeper 7 realizes by gudgeon or side projection 10, and these gudgeons or side projection arrangements and embed in the bar 6 of a pair of and evaporimeter 2 in the center of keeper 7.

The bottom 11 of keeper 7 overlaps with the pressure spots that keeper 7 is pressed on evaporimeter 2 pipes 5 just, thereby 11 li of pipe 5 these parts of embedding, thereby makes solid and reliable fastening of evaporimeter realization.

Keeper 7 generally has channel section, this is meant two side legs or the flank 12 of its underpart 11, engaging-in protruding 10 in the middle of also comprising simultaneously, even thereby projection 10 under normal circumstances be positioned on flank 12 outer surfaces, it also might be positioned on the inner surface of the parallel survey wing 12.

Be stressed that in addition keeper 7 relative transverse planes have symmetric construction basically, this transverse plane process projection 10, thereby two symmetric arms appear, thus bottom 11 is arranged on the two ends of parallel wing 12.Thus 1, can be by an end or the other end with pack into 8 li of the mountings of sidewall paneling 4 of groove of keeper 7.

However, the arm of keeper 7 may have dissymmetrical structure, and in other words, each arm may have different length.

In addition, the end of both wings 12 also refers to inclined-plane 13, and they 11 are inclined upwardly to keeper 7 two ends from the bottom.

Live in case keeper 7 is fastened, then they play the supporting of the conventional drawer 14 that is positioned at freezing tank 1 and the effect of guiding mechanism, and simultaneously, they play the backstop action when pulling out drawer.For this reason, drawer is provided with lower process 15 on its bottom surface.
