Definitions

  • the present invention relates to a machine for dry-cleaning articles such as clothes, household linen, towels, curtains and the like.
  • the present invention relates to the drying circuit of such a machine which is also designed to simultaneously perform an action, also known as abatement, removing from the articles the solvent used for dry-cleaning.
  • the condenser usually consists of the evaporator of a refrigeration circuit whilst the condenser of the same circuit forms the above-mentioned air heating element.
  • additional heating elements are used, positioned in series relative to the refrigeration system condenser.
  • Such additional heating elements are usually of the type with an electric heating element or steam powered.
  • heating elements are not without disadvantages. Irrespective of the specific type selected, it involves considerable energy absorption with consequent increases in the costs per dry-cleaning cycle.
  • the aim of the present invention is to overcome the above-mentioned disadvantage with a machine for dry-cleaning articles such as clothes, household linen, towels, curtains and the like, which allows the effective and economical execution of dry-cleaning and drying cycles for said articles, the machine being simple and economical to make and easy and practical to use.
  • the present invention also relates to a method for dry-cleaning articles.
  • the numeral 1 denotes as a whole the machine for dry-cleaning articles in accordance with the present invention.
  • the machine 1 comprises a drum 2 or container in which the articles to be dry-cleaned are inserted.
  • the drum 2 rotates, driven by motor elements of the substantially known type not described or illustrated, about an axis of rotation A.
  • the machine 1 comprises a closed circuit 3 for the circulation of air for drying the articles contained in the drum 2 which are not illustrated. As Figure 1 clearly shows, the drum 2 is positioned in the closed circuit 3.
  • the closed circuit 3 comprises a filtering zone 4 designed to catch any materials carried by the air flow, such as hairs and threads detached from the articles during drying.
  • the circuit 3 Downstream of the filtering zone 4, on the circuit 3 there is a fan 5 for moving the air. Downstream of the fan 5, again according to the direction of the arrows FA, the circuit 3 comprises an ascending duct 6 which conveys the air to a condensation battery 7 and to a heating element 8.
  • the condensation battery 7 is designed to condense the solvent in vapour form transported by the flow of drying air, whilst the heating element 8 is designed to raise the temperature of the air circulating along the circuit 3.
  • the solvent is sent to and drained from the drum 2 respectively from and to the collection tank 12.
  • the circuit 3 Downstream of the heating element 8 the circuit 3 comprises a descending duct 13 which introduces the heated air into the drum 2, thus closing the circuit 3.
  • the machine 1 comprises a refrigeration system 14 along which a respective refrigerant flows.
  • the refrigeration system 14 comprises, positioned one after another, a refrigerant compressor 15, a first condenser 16, a refrigerant receiver 17, a filter 18 for catching any impurities, a refrigerant expansion valve 19 and a first evaporator 20 for the refrigerant.
  • the above-mentioned elements of which the refrigeration system 14 consists are in fluid connection with one another by means of a plurality of pipes having numerous on - off and check valves. Both the pipes and the valves are described in detail below.
  • the first evaporator 20 and the first condenser 16 of the refrigeration system 14 are integrated in the closed circuit 3 to perform a heat exchange with the air circulating in it, and they respectively form the heating element 8 and the condensation battery 7.
  • the first condenser 16 and the first evaporator 20 are therefore two heat exchangers which, in the circuit 3, form respective means for the treatment of the air circulating in the circuit 3.
  • the refrigeration system 14 also comprises an auxiliary heat exchanger 22 which is positioned outside the circuit 3, so that it does not perform any heat exchange with the air circulating in the circuit 3.
  • the auxiliary heat exchanger 22 comprises a respective fan, not illustrated, designed to increase the efficiency of the heat exchange by establishing a forced air flow.
  • the machine 1 comprises a computerised control and operating unit for controlling the opening and closing of the on - off valves according to the different machine 1 operating steps.
  • a first element 23 for detecting the air temperature hereinafter indicated simply as the sensor 23.
  • the articles must be dried to remove the liquid solvent used for dry-cleaning from them.
  • the articles are struck by a flow of hot air.
  • the air treatment that is to say, basically its heating and the removal from it, by condensation, of the vaporised solvent, involves special operating steps by the refrigeration system 14 described above.
  • a first step of heating the air from an ambient temperature to to a predetermined temperature t 1 is carried out by activating the passage of the refrigerant through the first condenser 16 forming the circuit 3 heating element 8, but without allowing the refrigerant to circulate through the first evaporator 20 forming the circuit 3 condensation battery 7.
  • the air circulating in the circuit 3 is heated after the heat exchange which takes place at the heating element 8 and, therefore, its temperature is raised.
  • a second step with simultaneous heating of the air and condensing of the vapour contained in it takes place starting from the temperature t 1 until the air reaches a temperature t 2 higher than t 1 .
  • the refrigerant passes through both the first condenser 16 to heat the air, and through the first evaporator 20 to condense the solvent contained in the air in vapour form.
  • the first step of only heating the air is therefore a transient step in which the air is heated from the temperature to to the temperature t 1 .
  • the refrigerant coming out of the compressor 15 flows along the pipe T1 as far as the point P1 of intersection with the pipes T2 and T3. From the point P1, with the valve V4 open and the valve V5 closed, the refrigerant flows to the first condenser 16, in the direction indicated by the arrow F1.
  • the refrigerant As it passes through the first condenser 16, the refrigerant is condensed, transferring heat to the air circulating in the closed circuit 3, therefore said air is heated.
  • the refrigerant flows along the pipe T4 according to the direction indicated by the arrow F2 until it reaches the point P2 of intersection of the pipe T4 with the pipes T5 and T6.
  • a check valve 21 is advantageously positioned on the pipe T5 close to the point of intersection P3.
  • the refrigerant receiver 17 is of the known type and therefore its functions in the refrigeration system 14 are not described in detail.
  • the refrigerant coming out of the receiver 17 flows along the pipe T7 according to the direction indicated by the arrow F4 and reaches the expansion valve 19. Positioned along the pipe T7 there is a filter 18 for filtering the refrigerant coming out of the receiver 17, catching any impurities present in it.
  • the auxiliary heat exchanger 22 forms a second evaporator, alternative to the first evaporator 20.
  • the refrigerant does not flow through the first evaporator 20.
  • the refrigerant comes out of the auxiliary heat exchanger 22 through the pipe T10 along which it flows according to the direction indicated by the arrow F6 to the point P4 of intersection with the pipes T3, T6 and T11.
  • the air circulating in the closed circuit 3 is heated by heat exchange with the heating element 8 consisting of the refrigeration system 14 first condenser 16.
  • the transient cycle described above is repeated until the sensor 23 located downstream of the fan 5 detects air temperature values lower than a predetermined value t 2 , for example between 30°C and 40°C. Reaching the temperature value t 2 confirms the end of the transient step and the start of a refrigeration system 14 regular operation step.
  • a predetermined value t 2 for example between 30°C and 40°C.
  • the computerised control and operating unit referred to but not illustrated issues the command to close the valve V6 and simultaneously open the valve V1.
  • the refrigerant which expanded in the expansion valve 19 flows along the pipe T8 according to the direction indicated by the arrow F9, reaching the first evaporator 20 integrated in the drying circuit 3.
  • the refrigerant evaporates, absorbing heat from the moist hot air circulating in the closed circuit 3 and so causing the vaporised solvent present in said hot air to condense.
  • the refrigerant evaporated in the first evaporator 20 then flows along the pipe T13, according to the direction indicated by the arrow F10, towards the point P6 of intersection and from there, because the on - off valve V7 is closed, again into the compressor 15 through the pipe T12.
  • Machine 1 operation involves transient safety steps during which the refrigeration system 14 cycle is subject to transient modifications compared with its regular operation just described, so as to bring within predetermined safety ranges several parameters such as the air temperature in the circuit 3 or the pressure of the refrigerant in the refrigeration system 14.
  • a first transient safety step starting with normal regular operation, if the refrigerant coming out of the compressor 15 reaches a pressure value greater than a predetermined calibration value p 1 of a first pressure switch 24, the computerised control and operating unit closes the valve V4 and, at the same time, opens the valve V5.
  • the refrigerant coming out of the compressor 15, having reached the point P1 of intersection is diverted along the pipe T3 along which it flows according to the direction indicated by the arrow F11 and, having reached the point P4 of intersection, because the valves V3 and V7 are closed, it flows directly towards the auxiliary heat exchanger 22, through the pipe T10. This time, it flows along the pipe T10 according to the direction indicated by the arrow F12, that is to say, in the opposite direction to that during the transient starting step described above.
  • the computerised unit switches on the respective fan, not illustrated, belonging to the auxiliary heat exchanger 22, so as to make the release of heat to the outside even more efficient.
  • the auxiliary heat exchanger 22 forms a second condenser for the refrigerant, alternative to the first condenser 16.
  • the refrigerant flows along the pipe T6' according to the direction indicated by the arrow F13 and is reintroduced into the receiver 17. From the receiver 17, the refrigerant again flows through the pipe T7 and from there towards the expansion valve 19.
  • the first transient safety step is concluded as soon as the pressure switch 24 and/or the pressure switch 25 detect refrigerant pressure values less than their respective calibration values p 1 and p 2 .
  • a second transient safety step is implemented, starting with normal regular operation, if a second temperature detection element 26 detects a temperature greater than a predetermined safety value t s for the refrigerant entering the first condenser 16.
  • t s is advantageously approximately 95°C.
  • the computerised control and operating unit in the second transient safety step, if it is detected that the refrigerant has reached the temperature value t s , the computerised control and operating unit, not illustrated, by closing on - off valve V2 and simultaneously opening valve V3, diverts the flow coming out of the first condenser 16 along the pipe T6 along which it flows according to the direction indicated by the arrow F13. Having reached the point P4 of intersection, since both of the valves V5 and V7 are closed, the refrigerant flows directly towards the auxiliary heat exchanger 22, through the pipe T 10, along which it flows according to the direction indicated by the arrow F12.
  • the refrigerant transfers heat to the outside before returning to the receiver 17 and, from there, to the expansion valve 19.
  • the auxiliary heat exchanger 22 forms a second condenser for the refrigerant, additional to the first condenser 16.
  • the second transient safety step is ended and the computerised control and operating unit returns the valves V2 and V3 to their respective configurations adopted during regular operation of the refrigeration system 14, that is to say: valve V2 open and valve V3 closed.
  • the refrigeration system 14 comprises two additional pressure switches: a third safety pressure switch 27, positioned along the pipe T1, and a fourth pressure switch 28 for minimum pressure, positioned along the pipe T11, upstream of the compressor 15.
  • the third safety pressure switch 27 is designed, through the computerised control and operating unit with which it is connected, to stop machine 1 operation if the pressure of the refrigerant exceeds a predetermined safety pressure value.
  • the fourth pressure switch 28 is designed, through the computerised control and operating unit with which it is connected, to stop machine 1 operation if the pressure of the refrigerant is lower than a predetermined pressure value below which the refrigeration system 14 could be damaged.
  • valve means for the refrigeration system 14 form valve means for the refrigeration system 14.
  • valve means together with the computerised control and operating unit referred to but not illustrated, form control means for regulating the flow of refrigerant in the refrigeration system 14.
  • Figure 1 does not illustrate means for introducing the solvent into and/or extracting it from the drum 2, since these are of the substantially known type and are not useful to an understanding of the present invention.
  • Tests have shown optimum machine operation with the air temperature t 1 set at around 36 °C and the maximum temperature t s of the refrigerant set at around 95 °C.
  • temperature t 2 is closely linked to the type of articles being dry-cleaned and to the temperatures they can tolerate without deteriorating.
  • An average drying air temperature t 2 able to allow effective drying of articles is, for example, around 70 °C.
  • the present invention allows the treatment of the air for drying dry-cleaned articles without the need for thermal power in addition to that supplied by the refrigeration system normally coupled to the machine.
  • the thermal power generated with the refrigeration cycle is sufficient to dry the articles.
  • Tests have shown that, with the refrigerant indicated above, the air temperature on average reaches the value of 70 °C in very short periods of time and absolutely compatible with the duration of the dry-cleaning cycles currently used.
  • the machine 1 comprises a circuit 100 for cooling the solvent fed to the drum 2, the circuit 100 extending from the pipe T7, downstream of the filter 18 according to the direction indicated by the arrow F4.
  • the circuit 100 comprises an on - off valve V8, a cooler 101 and, inserted between them, an expansion valve 102.
  • the cooler 101 comprises a coil heat exchanger 103 outside which there flows the above-mentioned solvent to be sent into the drum 2.
  • Figure 2 does not illustrate the respective solvent feed and extraction ducts to and from the cooler 101, since they are considered to be of the substantially known type.
  • the on - off valve V8 the refrigerant coming out of the filter 18 is diverted to the cooling circuit 100 and expands at the expansion valve 102.
  • the refrigerant which expanded in the valve 102 flows along the circuit 100, reaching the cooler 101, where it evaporates, absorbing heat from the solvent circulating outside the coil heat exchanger 103, thus causing the solvent to cool.
  • the circuit 100 joins the pipe T12 again and the refrigerant then flows towards the compressor 15.
  • Use of the solvent cooling circuit 100 disclosed by the alternative embodiment illustrated in Figure 2 advantageously allows the temperature of the solvent to be kept within required values, thus guaranteeing, when necessary, the availability of low temperature solvent, for example for dry-cleaning delicate articles.
