Abstract

Portable stain removal device (1) comprising a detachable stain removal accessory (171) containing a stain removing material (300), whereby said portable stain removal device is suitable for implementing any combination of the following functions: stain removing using a chemical reagent, rinsing the stain residues and chemical residues, and evaporating water from the treated area of the garment.

First claim

The invention claimed is:

1. A portable stain removal device for locally removing a stain on a fabric, comprising:
a chemical container for containing a chemical reagent;
a dispensing mechanism for dispensing the chemical reagent out of the chemical container onto the fabric through a front head;
a heating plate arranged at the front head of the device for heating the fabric when the front head contacts the fabric; and
a heater arranged adjacent to the heating plate for heating the heating plate.

2. The portable stain removal device according to claim 1 , wherein the heater further heats the chemical reagent in the chemical container.

3. The portable stain removal device according to claim 1 , further comprising a liquid tank for containing water and/or a chemical neutralizer to be dispensed into the chemical container and/or onto the fabric.

4. The portable stain removal device according to claim 3 , wherein the heater further heats the liquid tank to generate at least one of hot water, or hot chemical neutralizer or steam.

5. The portable stain removal device according to claim 1 , wherein the chemical container comprises a cartridge detachable from the portable stain removal device.

6. The portable stain removal device according to claim 5 , wherein the chemical reagent is a liquid chemical reagent contained in the detachable cartridge the portable stain removal device further comprising:
a chemical-dosing nozzle; and
a pump for carrying the liquid chemical reagent from the detachable cartridge to the chemical-dosing nozzle in order to dispense the liquid chemical reagent onto the fabric.

7. The portable stain removal device according to claim 5 , wherein the chemical reagent is a powder or granule contained in the detachable cartridge, the portable stain removal device further comprising:
a chemical-dosing nozzle;
a water tank for holding water; and
a pump for carrying the water from the water tank to the detachable cartridge in order to form a chemical solution, and to carry the chemical solution from the detachable cartridge to the chemical-dosing nozzle.

8. The portable stain removal device according to claim 1 , further comprising:
a water tank for holding water;
a rinsing-water nozzle; and
a pump for carrying water from said water tank to said rinsing-water nozzle.

9. The portable stain removal device according to claim 5 , further comprising a temperature switch for selecting one of a first temperature setting and a second temperature setting of the heating plate.

10. The portable stain removal device according to claim 9 , wherein the temperature switch operates to select the first temperature setting to heat the heating plate to a first temperature after the detachable cartridge is attached to the portable stain removal device, wherein the first temperature is at least 65° C.

11. The portable stain removal device according to claim 10 , wherein the first temperature is between 65° C. to 140° C.

12. The portable stain removal device according to claim 9 , wherein the temperature switch operates to select the second temperature setting to heat the heating plate to a second temperature during a drying process of the fabric, wherein the second temperature is in a range of 100° C. to 170° C.

13. A method of treating a stained area of a fabric with portable stain removal device comprising a detachable cartridge containing a chemical reagent, a dispensing mechanism, a heating plate arranged at a front head of the device, and a heater, the method comprising:
heating the heating plate using the heater thermally connected to the heating plate;
coupling the detachable cartridge to the portable stain removal device;
dosing the chemical reagent in the form of a liquid from the detachable cartridge onto the stain area of the fabric through the front head using the dispensing mechanism; and
diffusing heat to the stained area via the heating plate, with a temperature of at least 65° C. when the front head is in contact with the fabric.

14. The method according to claim 13 , further comprising rinsing with water and/or a chemical neutralizer the stained area.

15. The method according to claim 13 , further comprising drying the stained area, by diffusing heat to the stained area via the heating plate, with a temperature in the range 100° C. to 170° C.

16. The method according to claim 13 , further comprising heating the chemical reagent in the detachable cartridge using the heater.

17. A portable stain removal device for locally removing a stain on a fabric, comprising:
a chemical container for containing a chemical reagent;
a dispenser for dispensing the chemical reagent out of the chemical container onto the fabric through a front head;
a heating plate arranged at the front head of the device for heating the fabric when the front head contacts the fabric; and
a heater arranged for heating the chemical reagent in the chemical container.

18. The portable stain removal device according to claim 17 , wherein the chemical container comprises a cartridge detachable from the portable stain removal device.

19. The portable stain removal device according to claim 18 , wherein the chemical reagent is a liquid chemical reagent contained in the detachable cartridge, the portable stain removal device further comprising:
a chemical-dosing nozzle; and
a pump for carrying the liquid chemical reagent from the detachable cartridge to the chemical-dosing nozzle in order to dispense the liquid chemical reagent onto the fabric.

20. The portable stain removal device according to claim 18 , wherein the chemical reagent is a powder or granule contained in the detachable cartridge, the portable stain removal device further comprising:
a chemical-dosing nozzle;
a water tank for holding water; and
a pump for carrying the water from the water tank to the detachable cartridge in order to form a chemical solution, and to carry the chemical solution from the detachable cartridge to the chemical-dosing nozzle.
