Definitions

  • This invention relates to a compressor comprising a valve table, which is used in household appliances, especially in cooling devices.
  • the high discharge speed, especially at the exhaust outlet, of the circulating fluid leaving the cylinder entering the cylinder head, will result in an increase of exhaust outlet losses. Furthermore the high temperature of the exhaust gas discharged into the cylinder results in heating of the cylinder head and this in turn results in heating of the circulating fluid that is sucked into the cylinder through the cylinder head. The entrance temperature of the circulating fluid sucked into the cylinder head directly affects the thermodynamic efficiency.
  • the object of the present invention is to design a compressor utilized in household appliances, especially in cooling devices, comprising a valve table, the thermodynamic efficiency of which is enhanced by facilitating the flow of the fluids circulating on it.
  • Figure 1 - is the sectional view of a compressor.
  • Figure 2 - is the perspective view of a valve table used in prior art.
  • Figure 3 - is the perspective view of a valve table.
  • Figure 4 - is the view of a valve table from above.
  • Figure 5 - is the exploded view of a body, a suction muffler, a suction valve plate, an exhaust valve plate, a cylinder head and a valve table.
  • Figure 6 - is the perspective view of a channel.
  • the compressor (1) utilized in household appliances especially in cooling devices comprises a motor (15), a body (16) upon which the components of the motor (15) are assembled, a cylinder (2) providing pumping of the fluid within, a suction muffler (4), preferably made of plastic enabling the circulation fluid, the acoustical energy of which is reduced, circulating inside to reach the cylinder (2) without heating up and preventing the noise that may be generated by the circulation fluid, a cylinder head (3) interconnecting the suction muffler (4) and the cylinder (2), leading the sucked and pumped circulating fluid, a valve table (5) enabling the sucking and pumping of the circulating fluid by forming a rigid and leakproof attachment between the cylinder (2) and the cylinder head (3), a suction valve plate (10) enabling suction of the fluid into the cylinder (2), an exhaust muffler (13) into which the circulating fluid inside the cylinder (2) is led enabling it to be transferred into the refrigerant cycle with attenuated pressure and noise,
  • the valve table (5) comprises an exhaust outlet (6) preferably with curvilinear form, covered by the exhaust valve plate (11), enabling the heated circulating fluid leaving the cylinder (2) to reach the exhaust muffler (13), a discharge outlet (7) preferably with curvilinear form, enabling the fluid coming out of the exhaust outlet (6) to be led to the exhaust muffler (13), a channel (8) interconnecting the exhaust outlet (6) and the discharge outlet (7) reducing the heating of the cylinder head (3) due to circulating fluid by helping the fluid leaving the cylinder (2) to quickly reach the discharge outlet (7), and a muffler recess (9) onto which the suction muffler (4) is seated.
  • the channel (8) comprises one or more steps (14) forming level differences on its base to reduce circulation losses, positioned according to and in forms and sizes suited for the circulation.
  • the circulating fluid going into the compressor (1) and through the suction muffler (4) is sucked by the cylinder (2) over the valve table (5) and pumped into the exhaust muffler (13) and out of the compressor (1) from the exhaust muffler (13).
  • the circulating fluid passing to the valve table (5) from the cylinder (2) by way of the exhaust outlet (6) reaches the discharge outlet (7) by way of the channel (8) in a short time, leaves the valve table (5) through the discharge outlet (7), reaches the exhaust muffler (13) by way of the discharge channel (12).
  • the circulation fluid going through the suction muffler (4), entering the cylinder (2) with high speed and pressure and leaving the cylinder head (3) quickly in order to minimize the losses produces an effect increasing the thermodynamic efficiency.
  • a discharge outlet (7) in elliptical form is utilized to reduce the circulation losses.
  • a channel (8) is utilized which is inclined from the exhaust outlet (6) towards the discharge outlet (7) with an angle of inclination ( ⁇ ), preventing the circulating fluid from leaving the surface of the base in order to reduce pressure losses resulting from the circulation.
  • an angle of inclination ( ⁇ ) less than 30ll is used to in order to prevent the fluid from leaving the surface.
  • valve table (5) comprises a channel (8) having different inclinations before and after the step (14).
  • the circulating fluid leaving the cylinder (2) with increased temperature due to high pressure and speed is enabled to leave the cylinder head (3) more quickly by means of the channel (8). Consequently both the pressure losses due to high speed of the circulating fluid is avoided and the increase in temperature of the cylinder head (3) due to the circulating fluid is reduced.
  • the suction muffler (4) that opens to the valve table (5) and the muffler recess (9) in the attachment geometry reduces the risk of the circulating fluid being heated by the valve table and enhances the thermodynamic efficiency.
