Description
456 300 10 15 20 25 30 35 2 fig. 4 visar det elektriska matningsutförandet och fig. 5 och 6 visar alternativa utföringsformer av relä- och kopplingsboxen enligt fig. 2 och 3. 456 300 10 15 20 25 30 35 2 Fig. 4 shows the electrical supply embodiment and Figs. 5 and 6 show alternative embodiments of the relay and switch box according to Figs. 2 and 3.
I fig. 1 avser hänvisningsbeteckningen 10 det yttre höljet av en avtätad kompressor som hålles i läge medelst lag- ringsorgan varav ett visas och omfattar en plåt 12, som är för- bunden med höljet, och ett fjädrande stöd 14 som vilar på botten- ytan 16 i ett rum 18 utformat på baksidan i den nedre delen 20 av ett kylskåp. Genom en sidomontering på höljet är start- och det termiska skyddsreläernas kopplingsbox 22, som utgör det aktuella uppfinningsföremålet, infäst på höljet och dess fram- sida är försluten medelst locket 24. Kopplingsboxen är ansluten till matningskretsarna medelst kablar 26.In Fig. 1, the reference numeral 10 denotes the outer casing of a sealed compressor which is held in position by means of storage means, one of which is shown and comprises a plate 12, which is connected to the casing, and a resilient support 14 which rests on the bottom surface. 16 in a room 18 formed on the back of the lower part 20 of a refrigerator. By means of a side mounting on the housing, the switch box 22 of the starting and the thermal protection relays, which constitutes the object of the present invention, is attached to the housing and its front side is closed by means of the cover 24. The switch box is connected to the supply circuits by cables 26.
Av fig. 4 framgår att den elektriska matningskretsen för motorkompressorn innefattar ett termiskt skyddsrelä 28, som är försett med en bimetalltunga 30 samt, i överensstämmelse med använd utföringsform, en värmeresistans 32 vars funktion kommer att beskrivas nedan. Reläet 28 är anslutet till en krets med två lindningar hos en elektrisk motor 34, närmare bestämt till arbetslindningen 36 och startlindningen 38.From Fig. 4 it can be seen that the electrical supply circuit for the motor compressor comprises a thermal protection relay 28, which is provided with a bimetallic tongue 30 and, in accordance with the embodiment used, a heat resistance 32 whose function will be described below. The relay 28 is connected to a circuit with two windings of an electric motor 34, more specifically to the working winding 36 and the starting winding 38.
I serie med startlindningen 38 ligger startreläet 40, som är av PTCR-typ (relä med positiv temperaturkarakteristik).In series with the starting winding 38 is the starting relay 40, which is of the PTCR type (relay with positive temperature characteristic).
Såsom framgår av fig. 2 är kopplingsboxen 22 utformad av en ytt- re kåpa 43 av plast inuti vilken startreläet 40 och det termiska skyddsreläet 28 är anordnade i kamrar åtskilda av väggar. På sin yttre bakvägg 42 är anslutningskammaren 44 försedd med skruv- anslutningar 46 och snabbkopplingsanslutningar 48 för inkoppling i kretsen enligt fig. 4. " Såsom framgår av fig. 3 och fig. 1 är det utrymme, som upptas av kopplingsboxen i ett plan utmed en linje som gär vin- kelrätt mot höljets 10 vertikala vägg enligt sträckan H i fig.1, ytterst begränsat. Dimensionen på denna utformning av kopplings- boxen är mycket reducerad i tvärriktningen. En ytterligare för- del erhålles, såsom redan angivits, genom att kopplingsboxen är anordnad på kåpans yttervägg och med anslutningarna vända mot operatören då denne lossat locket 24, såsom visas i fig. 1, vil- ket gör det enklare för operatören att ansluta huvudledningarna till anslutningsboxen liksom all annan erforderlig service. 10 456 300 3 I fig. 5 och 6 visas en annan konstruktionslösning som är avsedd att täckas av uppfinningen och där en annan typ av termiskt skyddsrelä 50 användes. I övrigt använda komponen- ter i utföringsfcrmen enligt fig. 5 och 6 överensstämmer med dem som tidigare beskrivits i samband med fig. 2 och 3 och har därför tilldelats samma hänvisningsbeteckningar som tidigare.As can be seen from Fig. 2, the junction box 22 is formed by an outer cover 43 of plastic inside which the starting relay 40 and the thermal protection relay 28 are arranged in chambers separated by walls. On its outer rear wall 42, the connection chamber 44 is provided with screw connections 46 and quick-connect connections 48 for connection in the circuit according to Fig. 4. As can be seen from Fig. 3 and Fig. 1, the space occupied by the connection box in a plane along a line perpendicular to the vertical wall of the housing 10 according to the section H in Fig. 1, extremely limited.The dimension of this design of the junction box is very reduced in the transverse direction.An further advantage is obtained, as already stated, by the junction box is arranged on the outer wall of the housing and with the connections facing the operator when he has loosened the cover 24, as shown in Fig. 1, which makes it easier for the operator to connect the main wires to the connection box as well as any other necessary service. 5 and 6 show another construction solution which is intended to be covered by the invention and where a different type of thermal protection relay 50 is used.Otherly used components in the embodiment according to Figs. 5 and 6 correspond to those previously described in connection with Figs. 2 and 3 and have therefore been assigned the same reference numerals as before.
Det termiska skyddet 50 enligt fig. 6 är av ett i och för sig.känt slag i samband med motorkompressorer medan det som betecknas med hänvisningen 28 i utföringsformen enligt fig. 2 är tillverkat av Sylvania och säljes på marknaden under benäm- ningen "glashöljesskydd". Detta är försett med en värmekälla 32, som har till uppgift att öka strömkänsligheten hos skyddet och till följd härav öka återgângstiden.The thermal protection 50 according to Fig. 6 is of a per se known type in connection with motor compressors, while the one designated by the reference 28 in the embodiment according to Fig. 2 is manufactured by Sylvania and is sold on the market under the name "glass casing protection". . This is provided with a heat source 32, which has the task of increasing the current sensitivity of the protection and consequently increasing the return time.
