DE202005013530U1 - The intake grille for cooling systems in leisure vehicles has alternative inserts for summer and winter use - Google Patents

Abstract

The intake grille in the vehicle used to generate cooling of a refrigeration system has metallic louvres (1) to allow a full air flow during transit. An alternative foam pad may be inserted during cold weather conditions restricts the air flow to prevent icing of the system.

Description

The The invention relates to a device for cooling refrigeration units in motorhomes. Caravans and the like. According to the preamble of claim 1 or the preamble of claim 5.

In Motorhomes, caravans and the like are usually arranged kitchen appliances. In heard of all rule to a cooling unit. This cooling unit becomes common cooled by the ambient air. These are on the outside of the motorhome, caravan or the like normally two recesses provided, with a recess arranged more near the floor is and for ventilation serves and a second recess at the level of the upper edge of the device and arranged for venting is provided.

Motorhomes, Caravans and the like are becoming increasingly popular not just in the summer also used in winter operation. This results in the problem that the cold liquid in the cooling units of the motorhome, caravan or the like from -20 ° C, if too cold air to the cooling unit arrives. So far, this problem has been solved by that the cooling units specially insulated and thermally conductive Elements were arranged between the cooker and a pipe to the evaporator, that prevented this pipe from getting too cold. That is, the refrigeration units were with a special cold insulation fitted.

This As a result, a high equipment outlay is necessary is to the refrigeration unit for the Use at low temperatures suitable. This leads to high Costs and increased Space requirements within the motorhome, caravan or the like.

task The invention provides a device for cooling cooling units, which is characterized by a possible simple and inexpensive device-related Equipment is distinguished to the refrigeration unit for use at suitable for low temperatures.

These The object is achieved by the characterizing features of claim 1 and claim 5, wherein appropriate training by those contained in the subclaims Characteristics are marked.

To proviso The invention relates to a device for cooling refrigeration units in motorhomes, Caravans or the like available placed, wherein in the recesses for ventilation different Calls can be introduced. As a result, the supply of cold fresh air can be limited. The cold fresh air mixes with the exhaust air of the cooling unit, so that the resulting temperature of the supply air to the cooling unit increased overall and the icing problem can not occur. The advantage In this case, in particular, that both for the summer and for winter operation a normal cooling unit can be used.

Appropriate way ventilation grids, Covers or the like. Used. This can be done as needed and in particular the season by controlling the supply air be achieved that ventilation grille with different number of ventilation slots or different huge vents The covers contain no or only very few or very small air vents.

In particularly convenient way is the ventilation grille for the Winter operation a deformed metal having a foam core and also a very small number of ventilation slots or very small vents having. The foam core serves to heat insulation, creating a further increase the temperature of the supply air to the cooling unit is reached.

A particularly preferred embodiment is to provide means that a snap, clip or other insertion of the ventilation grille, the cover or the like. Without tools or with only limited tools can be achieved. This will be the user of the motorhome a quick changeover of the motorhome allows, without that he must visit a workshop with his motorhome.

A particularly expedient embodiment is the sliding arrangement of an element in front of a ventilation grille. For example, a cover arranged displaceably in front of a ventilation grille be. As a result, in winter operation, the ventilation grille for summer operation be covered. By moving the cover, the air flow be controlled as needed. Is the ventilation grille or the cover Furthermore, not designed to be removable, so there is no risk that the ventilation grille or the cover can be lost and not later during retooling more available stand.

The Cover can by actuators changed in their position or it may be provided that the ventilation grille be removed must be able to hold the cover. The cover is then manually move. A fully automatic control of the cover by means of a motor is another variant.

A particularly preferred embodiment is the arrangement of a ventilation device in Floor area of the motorhome and a ventilation device in the roof area. In this case, the ventilation can be sealed according to the invention in winter operation or insulated or the number of ventilation slots be reduced. At particularly low temperatures may also the vent For example, be provided with a cover, which also Reduced or avoided the entry of cold air from this side can be.

Further Details and advantages of the invention will become apparent from the following detailed description of an embodiment by means of the accompanying drawings clear. Show:

1 a ventilation grille for summer operation in the side sectional view;

2 the ventilation grille from the front;

3 a representation of the recess with inserted ventilation grille for winter operation;

4 a sectional side view of the ventilation grille for winter operation;

5 the ventilation grille for winter operation in the inserted state;

6 a ventilation grille with sliding cover in the side sectional view;

7 the ventilation grille with sliding cover from the front.

In the 1 and 2 is a ventilation grille 1 shown for summer operation, which can be used in the recess for the supply or exhaust air, where in 1 a representation is shown in section and the 2 the ventilation grille for summer operation from the front shows. Furthermore, in the 2 latching 2 shown, which allow snapping or clipping of the ventilation grille in the recess. As a result, can be done quickly and without further aids required conversion from summer to winter operation.

3 shows a recess with inserted ventilation grille 1 for winter operation. In the 4 is the ventilation grille 1 shown in side section, wherein the structure of the ventilation grille according to the invention 1 with a deformed metal 4 and an inner foam core 3 , which serves the thermal insulation, becomes recognizable. By largely eliminating the ventilation slots of the ventilation grille 1 a reduction of the fresh air flow is achieved. After mixing with the warm exhaust air of the cooling unit, therefore, a relatively high internal air temperature, which is still sufficiently low to cool the cooling unit, is achieved. When comparing the 1 . 2 and 3 It can be seen that the different ventilation grilles and covers are inserted into the same recesses, in particular the frame basic structures are identical.

In the 5 is a ventilation grille according to the invention 1 shown in the lateral section after insertion into a recess for ventilation or ventilation. Here is a wall 5 of the motorhome recognizable.

The 6 shows a sliding cover in the lateral section 6 in front of a ventilation grille 1 can be pulled. By connecting the cover 6 with the wall 5 of the motorhome is losing the cover 6 locked out.

The 7 shows the cover 6 and the ventilation grille 1 , with all parts with the wall 5 of the motorhome are permanently connected. It can be provided the cover 6 to be able to proceed by means of guide rails, wherein the cover 6 from a position that the ventilation grille 1 does not cover, to a position in the ventilation grille 1 is completely covered, can be moved. It can also be achieved by this arrangement, intermediate positions and thus a targeted adaptation to the environmental conditions can be achieved. The guide rails are arranged for this purpose in the vicinity of the recess. To manually move the cover 6 Actuators may be provided. It is also conceivable that after removing the ventilation grille 1 through the then opened recess part of the cover 6 is taken and moved to the position that is desired. After selecting the position of the cover 6 will be the ventilation grille again 1 used.
