Definitions

• the invention relates to the assembly of facades on a housing.
• the invention finds particular utility in the assembly of facades on a condensing unit of a refrigerating machine.
• a condensing unit is generally assembled inside a box including a housing and a front closing the housing.
• the facade has a grid allowing outside air to exit the cabinet after cooling a heat exchanger of the condensing unit.
• the front is for example fixed to the housing by means of screws.
• the facade is generally more complex to achieve than the housing itself. It is for example formed of an outer frame ensuring its rigidity and a grid integral with the frame. The grid allows air circulation in the cabinet while preventing the penetration of large solid particles.
• the invention aims to overcome the problems of the solution described above by providing a particular assembly of several facades.
• the subject of the invention is a box comprising a front and a box, the front panel being fixed to the box, characterized in that the panel comprises means for maintaining in position against the box a second panel of the box.
• Figure 1 shows a cabinet with a single facade
• Figure 2 shows the cabinet of Figure 1 in which the facade is being assembled
• Figure 3 shows a cabinet with two identical facades
• Figures 4a to 4d show the cabinet of Figure 3 in which the facades are being assembled
• Figures 5a to 5f show a facade detail forming means for maintaining two facades between them.
• FIG. 1 shows a condensing unit 1 of a refrigerating machine for example for cooling a commercial premises.
• the condensing unit is fixed outside the room and allows the heat to be removed from the room to the outside.
• the condensing unit comprises a heat exchanger through which circulates a flow of air driven by a fan 2.
• the exchanger and the fan 2 are located in a box 3 having a housing 4 and a removable front 5.
• the facade 5 is formed of an outer frame 6 ensuring its rigidity and a grid 7 integral with the frame. In FIG. 1, the grid is not completely represented, revealing the fan 2 located inside the box 3.
• the panel 5 is for example held in position relative to the box 4 by means of screws 8.
• FIG. 2 shows the frontage 5 being mounted on the housing 4.
• the frontage 5 is positioned relative to the housing 4 by an upper side 9 of the frontage 5.
• the side 9 forms a tongue coming from to insert in a groove 10 of the housing 4.
• the movement of the facade 5 during the insertion of the tongue into the groove is represented by the arrow 1 1.
• Screws 8 may optionally lock the position of the side 9. Holes 14 of the tongue of the front and holes 15 of the groove can receive the screws 8 when they are in agreement. Other screws 8 can fix the lower side 12 against the housing 4.
• FIG. 3 shows a condensing unit 30 whose height is twice that of the condensing unit 1 shown in FIGS. 1 and 2.
• the box 31 comprises a housing 32 and two facades 5 and 35 advantageously identical.
• the two facades 5 and 35 are mounted head to tail on the housing 32, that is to say that the second facade 35 is turned relative to the first facade 5.
• the head-to-tail assembly makes it possible to simplify the design of the facades 5 and 35, in particular at the level of the fastening on the casing 32 by the side 12. This simplification will be better explained with the aid of FIGS. at 5f.
• Figures 4a to 4d show different mounting phases of the box 31.
• Figures 4a and 4b show the mounting of a first front 5 on an upper portion 33 of the housing 32.
• the mounting of the first front 5 is the same way only for the cabinet 3.
• the mounting operation shown in Figure 4a corresponds to the operation shown in Figure 1
• the operation shown in Figure 4b corresponds to the operation shown in Figure 2.
• the FIGS. 4c and 4d show the mounting of a second facade 35 on a lower part 34 of the casing 32. In FIG. 4c, the second facade 35 is brought close to the casing 32 and then turned back so that the side 12 of the second facade 35 is found in the vicinity of the side 12 of the first facade 5.
• the facade 35 is placed in position relative to the housing 32 by means belonging to the first facade 5. It is thus dispensed to provide other means of fixing the side 12 of the second facade 35 relative to the housing 32.
• the side 9 of the second facade 35 is then approached from the cabinet 32 in a movement shown in Figure 4d by means of the arrow 36 to be in the configuration of Figure 3 where the two facades 5 and 35 are in their assembled position relative to the housing 32.
• FIGS. 5a to 5f show a detail of the facades 5 and 35 forming means for maintaining two facades with respect to the housing 32.
• the two facades 5 and 35 are identical and are shown only on the sides 12 of each facade.
• the side 12 of the facade 5 comprises means for maintaining in position the front 35 against the housing 32.
• the fact that the two facades are identical makes it possible to standardize the manufacture of the facades. For example, it is possible to make the facades of molded plastic material.
• the identity of facades makes it possible to develop only one mold to make the facades and thus makes it possible to reduce the production costs.
• the mounting head to tail of two facades allows to predict growths, in this case the tabs 40, only on the side 12 without encumbering the opposite side 9. Outgrowths on the side 9 could hurt or at least interfere a user handling the boxes.
• the facade 5 comprises at least one tongue
• the facade 5 comprises three tabs 40.
• the tabs 40 form the means for holding the facade 35 in position against the case 32.
• the side 12 has an edge 41 shown in section in the figure
• Holes 42 make it possible to lock the position of the front panel 5 with respect to the housing 32, for example by means of screws 8.
• the tabs 40 are shown in section in Figure 5c and in enlarged detail in Figure 5d.
• the tongues 40 of the facade 5 are intended to cover the edge 41 of the facade 35 when the two facades 5 and 35 are in position against the housing 32.
• the tongues 40 of the facades 5 and 35 form slots interposing the in each other when facades 5 and
