Description

Technical field

The invention relates to a lighting device for a refrigerator, for example, for a refrigerator or freezer, for mounting in the inner chamber of the refrigerator. An air-lighting device comprises a fan and a luminaire, the fan serving to enhance the air flow through the surface of the heat exchanger and thereby improve the cooling effect of the heat exchanger, or to balance the temperature distribution in it by mixing the air of the inner chamber. The lamp is designed to illuminate the inner chamber.

State of the art

Refrigeration apparatuses are known in which the air-ventilation device forms a standardized module, which, as a ready-made pre-assembled unit, can be integrated into the internal chamber of the refrigeration apparatus.

The problem with such lighting and airway devices is that they do not have sufficient flexibility with respect to the lighting means used in the module. Usually, a suitable lighting means is selected based on the required lighting power, which in turn is determined by the dimensions of the inner chamber. Since the waste heat given off by the bulb is proportional to its light power, it is impractical to incorporate a bulb having a power greater than that required. In the case of a more powerful light bulb, a greater distance is required between the lighting device itself and the neighboring, possibly heat-sensitive, parts of the lighting-air device or housing of the refrigeration apparatus than in the case of a less powerful light bulb. The power-independent calculation of the light bulb will, therefore, lead to inefficient use of space in the case of small-sized refrigeration units. In addition, various lighting means are being used more and more in different models of refrigeration apparatuses to distinguish refrigerating apparatuses from each other by means of various lighting effects, and different holders in a lighting-air duct device require different holders with different space requirements. However, if different lighting means are used in the lighting and airway devices used so far, then for the manufacture of various models of refrigeration devices there must be many types of lighting and airway devices. Thus, certain types of air-lighting devices can only be manufactured in small quantities and, accordingly, at high cost.

Disclosure of invention

Therefore, an object of the present invention is to provide an air-lighting apparatus for a refrigeration apparatus that allows the use of various lighting means in various types of refrigeration apparatuses using a small number of different components.

The problem is solved by the fact that the lighting and airway device for the refrigerating apparatus has a main part that receives the fan, on the back side it carries fastening means for fastening in the inner chamber of the refrigerating apparatus, and on the front side it has an electrical connection, and also has lighting means through an adapter connected to an electrical connection. Since the lighting means is connected to the electrical connection via the adapter, only the adapter must be adapted to the special requirements for mounting the lighting means, and the electrical connection on the main part can be made the same for many adapters. Thus, only one version of the main part is required, which reduces the structural costs of its use in various models of refrigeration units.

It will be especially advantageous if the electrical connection has a socket, and the adapter has a plug that responds to the socket. Thus, no costly cable connection between the main part and the adapter is required, and both nodes can be easily connected to each other.

Particular advantages are offered by the design of the lighting-air device, if the holder of the lighting means is fixed to the main part, which is spaced from the front side and supports the adapter. If the adapter is fixed to the main part through the holder of the lighting means, then only the electrical connection to the adapter should be provided on the main body. The holder of the lighting means also makes it possible for other necessary modifications depending on the lighting means used or also regarding the design of the lighting-air device. Thus, also in the case of a greater need for space for the lighting means, only the holder of the lighting means should be adjusted in its shape, while the main part remains unchanged.

Regarding the installation of the air-lighting device, it will be especially advantageous if the holder of the lighting device has a hook included in the upper hole of the main part and a support supported on the front side of the main part. Thus, the holder of the lighting means can be very simply fixed by fitting onto the main part and, by means of a hook, is stably attached to its regular mounting location.

Further, the main part and the holder of the lighting means can expediently be attached to each other if the hook enters under the horizontal wall of the main part. Through this, the hook can hold the holder of the lighting means due to its weight and prevent the nodes from being unintentionally disconnected from each other during installation.

In the mounted state, the main part and the holder of the lighting means are preferably connected by the fact that the main part is so tightly mounted under the lid of the refrigerator that the movement of the holder of the lighting means forward, as a result of which it can be released from the upper opening of the main part, is blocked by the cover.

In addition, this gives the design of the lighting-air device additional advantages if the holder of the lighting means comprises a reflective screen extending above the lighting means. Since the reflective screen in its shape and size depends on the type of lighting means used, the adjustment can be implemented by modifying the holder of the lighting means, and there is no need to change the main part.

It will be especially advantageous if the adapter contains a transparent cap that at least partially surrounds the lighting means. Since some lighting products should not be taken with bare hands, the transparent cover creates protection against contact with the lighting device. The adapter forms, together with the lighting means and with the cap, an easily-controlled device, which in case of a defect in the lighting means can very easily be replaced as a whole. In addition, due to the appropriate type of cap, it is possible to even more positively influence the effect of the light emitted by the lighting means.

The implementation of the invention

Figure 1 presents a schematic sectional view of a refrigeration apparatus in which a lighting and airway device 1 is integrated in the upper rear corner of the inner chamber 91. A lightning and airway device 1 comprises a main part 2, a holder 5 of lighting means and an adapter 4.

The main part 2 by means of fixing means (not shown) is fixed in the shown position on the rigid inner shell of the housing 92. The main part 2 carries a fan 3 and an air filter 6. On the front side of the main part 2 there is a holder 5 of the lighting means, which carries the adapter 4. The adapter 4 comprises a lighting means 41, a transparent cap 42 and a cap 44.

The shell 7, which tightly fits the lighting-air device 1, is mounted on the lighting-air device 1. The shell 7 has openings for air inlet and outlet and a transparent section, which is located next to the lighting means 41, so that the light emitted by it passes into the inner chamber 91 The transparent portion may also be replaced by an opening from which the front part of the adapter 4 containing the lighting means 41 protrudes, as well as possibly any part of the holder 5 of the lighting means.

Compressor 93 is per se known in its own way in the rear niche of housing 92.

Fig. 2a shows an enlarged schematic sectional view of the holder 5 of the lighting means of the lighting device 1 with an adapter 4 located thereon.

The holder 5 of the lighting means contains a bracket 51, which is made in the form of an elongated horizontal plate in the form of a narrow rectangle. At the front end of the narrow side of the bracket 51, it passes into the reflective screen 55. The reflective screen 55 is also made by means of a rectangular horizontal plate and relatively widened relative to the bracket 51 on both sides, the extended sides being slightly rounded down. Thus, the highest point of the reflective screen 55 continues the bracket 51 forward.

Narrow struts 52, 52 ′ are made at the rear end of the bracket 51 facing away from the reflective screen 55, spaced apart from the upper and lower sides of the bracket 51. The struts 52, 52 ′ extend over the entire width of the bracket 51, are distant from the rear end of the bracket 51, and protrude above the bracket 51 up or down approximately the wall thickness of the bracket 51. At the rear end, the bracket 51 is flat.

An essentially annular fastening 56 is made on the bracket 51 in the downward direction of attachment of the reflective screen, and a part of the reflective screen 55 goes into the external bend of the mount 56. The bend of the reflective screen 55 roughly transforms into the external bend of the mount 56. Rectangular on two outer sides of the mount elongated sidewalls 57 that are perpendicular to the plane of the bracket 51 and extend parallel to the bracket 51 towards its rear end, the sidewalls 57 being shorter than the bracket ENU 51. In the shown projection, only the sidewall 57 is visible, which is made on the holder 5 of the lighting means on the side facing away from the observer. The sides 57 at the end facing away from the fastening 56 pass into a slightly expanded support 54.

The base 44 of the adapter 4 is inserted into the mount 56, and by means of a suitable fixing (not shown), the base 44 is unintentionally disconnected from the mount 56. The base 44 carries the lighting means 41 and the transparent cap 42 surrounding the lighting means 41, the lighting means 41 and the cap 42 stand for the mount 56 in the direction of the reflective screen 55 located above it. The end of the base 44 facing the lighting means 41 forms a plug 43, which also protrudes from the mount 56 on its side. Inside the base 44 zdo 23 is connected to the electrical connection of the lighting means 41.

2b also shows an enlarged schematic sectional view of the main part 2 of the lighting-air device 1.

The main part 2 has a substantially rectangular shape. On the upper side, the main part 2 is bounded by a horizontal wall 24, to which the front wall 27 adjoins in the direction of the front side. The front wall 27 extends only along the upper part of the main part 2 and leaves a hole in the lower part in which the air filter 6 is located in the outgoing position obliquely back relative to the front wall 27. The air filter 6 is held with the possibility of separation and replacement on the main part 2 on the rigid grill 61 by means of hooks 62 covering the edges of the filter 6. Further, the main part 2 og An'ichi on two sides by side walls 26, of which the figure shows only the side wall facing away from the observer. The front wall 27 along the side edges is adjacent to the side walls 26. In the region bordering downward on the front wall 27, the side walls 26 are beveled, and the bevel is close to the position of the air filter 6.

In the middle region of the main part 2, it receives a fan 3, which is held by the side walls 26 and the bottom of the main part 2. The side walls 26 extend beyond the fan 3 towards the rear wall of the main part 2 and pass into two side surfaces 28, of which again, only the side surface facing away from the observer is represented. The side surfaces 28 form a rear locking of the main part 2, and the rear edge of the side surfaces 28 facing the fan 3 in the upper region can be rounded and made so that it fits to the shape of the upper corner of the inner chamber 91 of the refrigeration unit when the lighting-air device is mounted inner chamber 91.

On the rear side of the main part 2 there are two fastening means 20 connected through a nozzle to the side surfaces 28 and protruding forward from the outside relative to the side surfaces. The fastening means 20 are in the form of a lying cylinder, the outer surface of the cylinder being flush with the rear edge of the side surface 28. A through hole passes through the cylinder axis of the fastening means 20, which receives the shaft of the fastening bolt 21, with which the main part 2 is fixed in the inner chamber 91 of the refrigerator apparatus. Since the fastening means 20 in the shown projection is closed by the side surface 28, the fastening means 20, including the closed area of the fastening bolt 21, are represented by dashed lines.

A cutout 25 is made in the horizontal wall 24, which creates a substantially rectangular hole in the horizontal wall 24, is located in the middle on the leading edge of the horizontal wall 24 facing the front wall 27, and is directly adjacent to this edge. The dimensions of the cutout 25 are selected such that its width corresponds to the width of the bracket 51 of the holder 5 of the lighting means, and its depth only slightly exceeds the length of the bracket 51 from the spacers 52, 52 'to its rear end 53.

In the area of the front wall 27 of the main part 2, a socket 51 is located that brings out the contact of the electrical connection 22 from the main part 2 and has the form corresponding to the plug 43 on the adapter 4. The electrical connection 22 has an electric wire 9 that connects the socket 51 to the supply wire 91 outgoing from the refrigerator. Also, the fan 3 has an electrical connection to the supply wire 91, and for this, another electric wire 92 branches off from the wire 9.

Figure 3 shows a schematic fragment of a section of the lighting-air device 1 in the connection area between the main part 2 and the holder 5 of the lighting means.

To mount the holder 5 of the lighting means on the main part 2, the holder 5 of the lighting means rotates counterclockwise from the horizontal position shown in figa, and the bracket 51 at its rear end 53 is inserted from above into the cutout 25 of the main part 2. At the same time, the bracket 51 immersed in cutout 25, including spacers 52, 52 '. When the holder 5 of the lighting means is returned to its horizontal position, the upper edge of the front wall 27 enters the cutout region 25 on the side of the spacer 52 facing away from the main part 2. At the same time, the end 53 of the bracket 51 lies under the horizontal wall 24. Thus, the rear end 53 and the spacer 52 interact according to the principle of a hook that fits under the horizontal wall 24. In the lower region of the holder 5 of the lighting means, the sides 57 are supported by their expanded ends 54, acting as supports, from the outside to the front Yu wall 27. Thus, the holder 5 of the lighting means is firmly fixed on the front side of the main body 2.

After mounting in the inner chamber 91, the horizontal wall 24 of the main part 2 is adjacent to the cover of the housing 92. Since the spacer 52 'also touches the cover, the holder 5 of the lighting means cannot be lifted and disconnected from the hole 25. Therefore, the user can conveniently replace the adapter 4 with the lighting means 41, and there is no need to be afraid of disconnecting the holder 5 of the lighting means.

At the same time, when connecting the main part 2 and the holder of the lighting means 5, the plug 43 of the adapter 4 is pressed into the socket 23 on the main part 2, and thus, the lighting means 41 is connected to the electrical connection 22.

The adapter 4 forms a compact assembly, which can very easily be inserted into the mount 56 without touching the lighting means 41. To use another lighting means 41, the base 44 and the transparent cap 42 must be fitted to each other. However, the portion of the base 44 provided for contact with the main part 2 always remains the same, and thus, there is no need to change the design of the main part 2.
