Description

  The present invention relates to a dry cleaning apparatus used during dry cleaning.

  In a conventional dry cleaning apparatus, for example, a cleaning object such as clothes is put into a drum-shaped dry cleaning apparatus main body, and the dry cleaning apparatus body is rotated for a predetermined time in a state where a dry cleaning solvent is injected. It was to be washed.

  However, since the conventional dry cleaning apparatus is a mode in which cleaning is performed in a predetermined cleaning time regardless of the degree of contamination of each cleaning target, a cleaning target that is insufficiently cleaned in the predetermined cleaning time or excessive cleaning is performed. There is a problem that variations in the finish are likely to occur, such as the occurrence of a cleaning object.

  It is also possible to increase the cleaning time for highly dirty objects to be cleaned, but the cleaning time can only be changed manually, and the work itself is very troublesome. In addition, since there was no clear standard for grasping whether or not the dirt was removed, the cleaning operation could not be performed smoothly and accurately.

  The present invention has been made paying attention to such a problem, and the main purpose is to automatically change the cleaning time according to the degree of contamination of each cleaning object. An object of the present invention is to provide a dry cleaning apparatus capable of producing a beautiful finish without variation.

To do.

  If this is the case, the transparency of the solvent is detected one by one by the transmittance sensor, compared to the conventional mode, that is, the mode in which the cleaning object is cleaned for a predetermined time regardless of the degree of contamination of the cleaning object. The cleaning object is automatically washed until the value is reached, so that it is possible to deal with the degree of contamination of each cleaning object individually and specifically, so that each cleaning object can always be finished neatly and cleaning work can be performed. It is rich in practicality that can be performed smoothly and accurately.

  Further, another dry cleaning apparatus of the present invention having substantially the same effect includes a dry cleaning apparatus main body, a filter capable of purifying the dry cleaning solvent, and the dry cleaning solvent discharged from the dry cleaning apparatus main body to the filter. A discharge path that guides, a supply path that supplies the dry cleaning solvent that has passed through the filter to the dry cleaning apparatus body, a permeability sensor that detects the transparency of the dry cleaning solvent that is interposed in the discharge path and returns to the filter, And a controller that outputs a signal to stop the cleaning of the object to be cleaned when the transparency of the dry cleaning solvent detected by the transmittance sensor reaches a certain value or more. .

  As described above, according to the present invention, the cleaning time can be automatically changed according to the degree of contamination of each cleaning object, and each cleaning object can be finished with a clean finish. is there.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the dry cleaning apparatus 1 according to this embodiment includes a dry cleaning apparatus main body 2, a filter 3 that can purify a dry cleaning solvent (hereinafter abbreviated as “solvent”), and a dry cleaning apparatus main body 2. A discharge path 4 that guides the solvent discharged from the filter 3 to the filter 3 and a supply path 5 that supplies the solvent that has passed through the filter 3 to the dry cleaning device main body 2 are provided. In this embodiment, bentafluorobutane (HFC-365mfc) having a characteristic that the ozone layer cannot be destroyed is applied as the solvent, and the flow of the solvent is indicated by arrows in FIG.

  The dry cleaning apparatus main body 2 includes a cleaning drum 21 that cleans an inputted cleaning object. In the present embodiment, the dry cleaning apparatus main body 2 is provided with a distillation pot 22 that distills and purifies the solvent containing the dirt component through the object to be cleaned.

  In this embodiment, a spin disk filter is applied as the filter 3. The filter 3 is precoated with diatomaceous earth, carbon is further adhered to the diatomaceous earth, and the solvent can be purified by passing the solvent through the filter 3.

  The discharge path 4 is a path connected from the cleaning drum 21 of the dry cleaning device body 2 to the filter 3, and a button trap / drain tank inlet valve 41 provided in association with the distillation kettle 22 on the discharge path 4, and a cleaning A first pump for feeding the solvent discharged from the drum 21 and a distillation pot inlet valve 43 connected to the distillation pot 22 are provided.

  The supply path 5 is a path connected from the filter 3 to the cleaning drum 21 of the dry cleaning apparatus main body 2, and a cleaning drum inlet valve 51 is provided on the supply path 5.

  Thus, the dry cleaning apparatus 1 according to the present embodiment is provided with a permeability sensor 6 that detects the transparency of the solvent that returns from the dry cleaning apparatus body 2 to the filter 3 on the discharge path 4. The detected value is compared with a predetermined reference value (a value indicating that the dirt component has been removed from the cleaning object), and when the value detected by the transmittance sensor 6 reaches the reference value, a cleaning stop signal is generated. An output determination unit 6a is provided. The determination unit 6a is controlled by a control unit (not shown).

  In the present embodiment, an existing one is applied as the transparency sensor 6, and the value detected by the transparency sensor 6 is output to the determination unit 6a. A sight glass (not shown) may be provided in association with the transmittance sensor 6 so that the transparency of the solvent can be visually recognized.

  The determination unit 6a outputs a cleaning stop signal when the value detected by the transmittance sensor 6 reaches a reference value, and the cleaning signal may be output as sound or light.

  The control unit includes, for example, a CPU and the like. The control unit is configured to rotate the cleaning drum 21, to inject a solvent into the cleaning drum 21 of the dry cleaning apparatus main body 2, to clean the cleaning target, It mainly controls the washing-out washing process, the drying process for drying the object to be cleaned, switching between these processes, and the like.

  Further, the dry cleaning apparatus 1 according to the present embodiment includes a new liquid tank 7 for storing a new solvent, a spin tank 8 connected to the new liquid tank 7 via a solvent supply valve 7a, and a powder charging trap. 9 and a second pump 10 for feeding a new solvent to the supply path 5.

  Next, the dry cleaning process and operation of the dry cleaning apparatus 1 having such a configuration will be described.

  First, when a solvent injection process is selected in a state where a cleaning object is put into the cleaning drum 21 of the dry cleaning apparatus main body 2 or in a state before being put, a predetermined amount of solvent is washed from the spin tank 7 via the supply path 5. The detergent is poured into the drum 21, and the detergent is subsequently put into the cleaning drum 21.

  Next, when the cleaning process is selected, the dirt component adhering to the cleaning object in the cleaning drum 21 is eluted in the solvent. Then, the solvent containing the dirt component is discharged from the cleaning drum 21 to the discharge path 4, and the transparency is detected by the permeability sensor 6 provided on the discharge path 4, and subsequently passes through the filter 3, and the supply path 5 Is supplied to the cleaning drum 21 again. The transparency value detected by the transparency sensor 6 is output to the determination unit 6a (control unit), and the cleaning process is automatically continued until the transparency value detected by the transparency sensor 6 reaches a predetermined reference value. Thus, the value detected by the permeability sensor 6 by the determination unit 6a is compared with a predetermined reference value, and a cleaning stop signal is output when the value detected by the permeability sensor 6 reaches the reference value. As a result, the washing process is stopped, and then the process proceeds to the washing process and the drying process, and all the dry cleaning processes are completed through each process.

  As described above, the dry cleaning apparatus 1 according to the present embodiment includes the dry cleaning apparatus main body 2, the filter 3 that can purify the solvent, and the discharge path 4 that guides the solvent discharged from the dry cleaning apparatus main body 2 to the filter 3.

A determination unit 6a that compares a value detected by the sensor 6 with a predetermined reference value and outputs a cleaning stop signal when the value detected by the permeability sensor 6 reaches the reference value is provided. Therefore, compared with the conventional mode, that is, a mode in which cleaning is performed in a predetermined time regardless of the degree of contamination of an object to be cleaned such as clothes, the transparency of the solvent is detected by the permeability sensor 6. Since the cleaning process is automatically continued until the transparency reaches a certain level or more, it becomes possible to respond specifically to the degree of contamination of each cleaning object, resulting in excessive cleaning and insufficient cleaning. And a good finished state with no variation.

  The present invention is not limited to the embodiment described in detail above.

  For example, although bentafluorobutane is applied as the solvent in the embodiment, the present invention is not limited to this, and a petroleum-based solvent may be applied.

  Further, as a filter, a filter having another structure may be applied instead of or in combination with the spin disk filter.
