Definitions

  • the invention relates to a refrigerator and the like with at least one thermostat whose sensor detects the temperature of an evaporator surface, the connection between the sensor and the thermostat being guided through a pipe which is at least partially laid behind the inner wall, preferably inside the insulation.
  • the senor Even in refrigerators in which the evaporator is foamed in, the sensor has been attached to the evaporator surface in the refrigerator compartment. The sensor is visible again and is a hindrance when cleaning the refrigerator.
  • the invention has for its object to provide a refrigerator of the type described, in which the temperature sensor can be easily replaced and the inner surface of the cooling room remains free of sensor elements with reliable temperature detection.
  • the tube runs in the wall of the refrigerator over the entire length, so that it is not visible.
  • the inner walls of the cold room are smooth so that they can be cleaned without difficulty.
  • the sensor and / or the pipe will be damaged during the cleaning process.
  • the pipe is reliably secured with the bracket in the installed position.
  • the sensor housed in the tube on the other hand, can be pulled out, so that simple repair to the sensor or rapid replacement of the sensor is possible. A new sensor can be easily inserted through the pipe to the evaporator.
  • the inner housing 1 of a refrigerator is surrounded by insulation (not shown).
  • the housing 1 has a freezer compartment 2, which is surrounded by an evaporator plate 3.
  • Another evaporator plate 4 is attached to the rear wall 5 of the housing 1.
  • This evaporator plate 4 is connected to the evaporator plate 3.
  • the sensor 60 of a thermostat (not shown) is connected to the evaporator plate 4 and is arranged in the refrigerator cooling compartment.
  • the sensor 60 is housed in a tube 6, which is preferably flexible, so that it can be installed depending on the installation conditions and the design of the housing 1. Near its free end, the tube 6 is fastened to the evaporator 4 and / or to the housing 1 with a holder 7.
  • the space between the housing 1 and a body, not shown, is filled with insulation material.
  • the tube 6 is foamed in here, so it is completely in the insulation.
  • the evaporator sheets 3 and 4 are also foamed into the insulation and lie flat with their inner sides in the inner wall of the freezer compartment 2 and the refrigerator compartment.
  • the holder 7 has a substantially rectangular base 8 with a U-shaped cross section. It has a flat web 9 and at right angles to legs 10 and 11, which form the longitudinal side walls of the base body 8 (FIG. 5). On the narrow sides of the base body 8 there are also walls 12 and 13 running perpendicular to the web 9 (FIG. 4), which have the same height as the legs 10, 11 and are connected to them.
  • the base body 8 with the flat web 9 and the flat side walls 10 to 13 is thus trough-shaped.
  • it can be provided with at least one stiffening rib which extends between the legs 10 and 11.
  • a bearing part 14 with a U-shaped cross section is provided on the bracket 7, which has a flat web 15 and vertically projecting legs 16 and 17 (FIG. 5).
  • the integrally formed bearing part 14 is the same length as the base body 8 (FIG. 2) and also has a rectangular outline in plan view. The distance between the legs 16 and 17 is adapted to the outer diameter of the tube 6, which is laid between the two legs.
  • a rectangular groove 22 is formed between the adjacent legs 11 and 16. Since the tube 6 usually has a circular cross section, the web 15 of the bearing part 14 can also be curved such that it lies flat against the tube 6 in the installed position.
  • An approximately triangular web 23 and 24 projects from the side walls 12 and 13 of the base body 8 approximately vertically (FIG. 2).
  • a rib 27 and 28 protrudes from the side walls 12 and 13 of the base body 8, which is perpendicular runs to the web 23, 24 and to the side walls 12 and 13. 3 shows, the height of the rib 27 decreases steadily from the side wall 12 of the base body 8 to the outside.
  • the height of the rib 28 initially decreases from the side wall 13 and then remains constant from approximately half the length of the rib. In the connection area to the side walls 12 and 13, the ribs 27 and 28 have the same height as these walls.
  • the rib 27 is angled approximately in half length at a slight angle in the direction of the leg 10.
  • the opposite rib 28 has approximately a half length of a preferably right-angled shoulder 31 which merges into a rib piece 32 which also runs obliquely in the direction of the leg 10 of the base body 8.
  • the angled part of the rib 27 is adjoined on the side facing away from the web 23 by a support 34, the underside (FIG. 3) of which lies in one plane with the end faces of the legs 10 and 11 of the base body 8.
  • the top of the support 34 is formed as an inclined surface which rises in the direction of the free end of the rib 27.
  • a support 40 also adjoins the angled fin piece 32 at right angles, the underside (FIG. 3) of which lies in one plane with the underside of the other support 34 and the top of which is designed as an inclined surface.
  • a rib 43 is provided on the support 40 and runs parallel to the rib piece 32. The rib piece 32 and the rib 43 delimit a U-shaped receptacle.
  • the entire bracket 7 is advantageously made in one piece from plastic. It forms a pre-assembly unit, which can already be fitted with the tube 6 before being attached to the housing 1.
  • the thermostat is mounted on the inside of the cooling space and the pipe 6 is guided through the wall 48 (FIG. 1) of the housing 1.
  • the flexible tube 6 is then inserted into the holder 7 in such a way that it runs through the recess 49 (FIG. 2) between the bearing part 14 and the fin piece 32 and the fin 43.
  • the tube 6 is then inserted into the opposite recess 50 between the bearing part 14 and the support 34. In this position, the flexible pipe runs in an arc in the area below the bearing part. This bent part is then pressed between the legs 16 and 17 of the bearing part 14.
  • the tube 6 Since the supports 34 and 40 are provided with the inclined surfaces 36 and 42, which run obliquely opposite one another, the tube 6 is clamped in the area between the bearing part 14 and the respective supports, so that the holder 7 sits firmly on the tube 6. Since the rib piece 32 and the rib 43 lie obliquely to the longitudinal axis of the bearing part 14, the tube 6 is not only bent upwards but also laterally, as a result of which the holder 7 is securely seated on the tube 6.
  • the distance between the legs 16 and 17 of the bearing part 14 is preferably slightly smaller than the diameter of the tube 6, so that the part of the tube lying in the bearing part 14 is clamped between the legs. The holder 7 therefore sits securely on the tube 6 in the respective position.
  • the web 15 In order to prevent the pipe 6 from kinking in the outlet area from the bearing part 14, the web 15 is provided with bevels 52 and 53 on its underside 51 in the outlet area (FIG. 4).
  • the bracket 7 thus pre-assembled on the tube 6 is then attached to the housing 1 or the evaporator 4.
  • the bracket 7 is placed with its legs 10 and 11 on the housing 1 at the installation site and for example with Ultra sound welded to him.
  • the holder can also be connected to the housing 1 in any other suitable manner.
  • the holder 7 is preferably fastened in the edge region of the evaporator sheet 4. It has a tab 54 (FIG. 5) which is bent out at right angles and engages in the groove 22 between the bearing part 14 and the base body 8.
  • the evaporator plate 4 is additionally secured in the edge region by the holder 7 against detachment from the housing 1. Otherwise, the evaporator plate 4 is fastened to the housing 1 by means of an adhesive film 55.
  • the tube 6 is pressed firmly against the evaporator plate 4 over a sufficiently large length, so that a sufficient contact area is ensured.
  • the evaporator end 61 of the tube is closed.
  • the tube 6 is arranged with respect to the holder 7 that it protrudes from the bearing part 14 so far that length tolerances of the sensor 60 can be compensated.
  • the protrusion of the tube 6 is so large that, taking into account the length tolerances, the sensor 60 extends over the entire length of the bearing part 14.
  • the senor 60 can simply be pulled out of the tube 6 and a new sensor can be inserted effortlessly.
