Description

Technical Field

[0001] The utility model relates to the technical field of surface cleaning equipment, in particular to a fabric cleaning machine. Background Art

[0002] The steam-type fabric cleaning machine is an efficient cleaning device. It penetrates into the fabric fibers by spraying high-temperature steam to effectively remove stains, bacteria, and dust mites. When the traditional steam-type fabric cleaning machine is in use, in order to avoid the working temperature of the boiler of the fabric cleaning machine from being too high, after the user plugs in the power supply, it is often necessary to wait for a preset time before starting the switch to operate the cleaning head to spray hot steam. However, when the room temperature is relatively high or the fabric cleaning machine has been used for a period of time and is only briefly powered off, at this time the temperature of the boiler is already in a relatively high state. When the user powers on the fabric cleaning machine again, the fabric cleaning machine still needs to be preheated for a period of time before it can be used. This easily causes the temperature of the boiler of the fabric cleaning machine to be too high, and the user needs to wait for a long time before continuing to use the fabric cleaning machine for cleaning operations. This not only brings inconvenience to the user in terms of operation, but also the long-term over-high temperature state of the boiler is likely to cause safety and reliability problems, and is likely to shorten the service life of the fabric cleaning machine.

[0028] The electronic control unit 30 includes a controller 31, a temperature detection element, an indicating element 38, and a switch 34. The controller 31 is respectively signal-connected to the temperature detection element, the indicating element 38, and the switch 34, and the controller 31 is respectively control-connected to the water pump 22 and the heating boiler 23. The controller 31 is configured to: when the temperature of the heating boiler 23 reaches a first preset temperature, the controller 31 controls the indicating element 38 to send out an indication signal externally, and when the temperature of the heating boiler 23 reaches the first preset temperature and the switch 34 is triggered, the controller 31 controls the water pump 22 to start, and when the temperature of the heating boiler 23 reaches a second preset temperature greater than the first preset temperature, the controller 31 controls the heating boiler 23 to stop heating.

[0029] As shown in Figure 2 , the temperature detection element includes a first temperature control element 32. The first temperature control element 32, the switch 34, the water pump 22, and the controller 31 are electrically connected through a first circuit 36. The first temperature control element 32 is configured to conduct the first circuit 36 when the temperature of the heating boiler 23 reaches the first preset temperature. Wherein, the controller 31 is an electronic control board, the first temperature control element 32 is a normally open thermostat, the first preset temperature is 105 °C, and the indicating element 38 is a signal indicator light. In other embodiments, the controller 31 may also be a control chip, the first temperature control element 32 may also be a temperature control switch 34 or a thermostat, the first preset temperature may also be set within the range of 100 °C to 105 °C, and the indicating element 38 may also be one of a buzzer, a vibrator, and a display, without specific limitation.

[0030] As shown in Figure 3 , to prevent the heating boiler 23 from continuously heating and causing the temperature of the heating boiler 23 to be too high. The temperature detection element further includes a second temperature control element 33. The second temperature control element 33 and the heating boiler 23 are electrically connected through a second circuit 37. The second temperature control element 33 is configured to disconnect the second circuit 37 when the temperature of the heating boiler 23 reaches the second preset temperature. Wherein, the second temperature control element 33 is a normally closed thermostat. The second preset temperature is 110 °C. In other embodiments, the second temperature control element 33 may also be a temperature control switch 34 or a thermostat, the second preset temperature may also be set within the range of 105 °C to 110 °C, or may also be other temperature values greater than or equal to 105 °C, without specific limitation.

[0031] To facilitate power supply to the first circuit 36 and the second circuit 37, the fabric cleaning machine 100 further includes an electrical connector 35 that is electrically connected to the first circuit 36 and the second circuit 37 respectively, and the electrical connector 35 is an electrical plug suitable for electrical connection to the mains. In other embodiments, the electrical connector 35 may also be an electrical connection terminal suitable for electrical connection to a DC power supply, without specific limitation.

[0032] The working principle of the fabric cleaning machine 100 in this embodiment is as follows: When the user uses the fabric cleaning machine 100, the electrical plug is electrically connected to the mains power, such as plugging the electrical plug into the socket on the wall socket, socket or extension cord. After the fabric cleaning machine 100 is powered on, the normally open thermostat, the normally closed thermostat and the heating boiler 23 immediately start to work. The normally open thermostat and the normally closed thermostat continuously detect the temperature of the heating boiler 23 and feedback the temperature signal to the electronic control board. When the normally open thermostat detects that the temperature of the heating boiler 23 reaches the first preset temperature (such as 105 °C), the normally open thermostat closes, and the first circuit 36 is immediately turned on. At this time, the electronic control board sends a control signal to the indicator light, and the controller 31 controls the indicator light to light up, reminding the user that the heating boiler 23 has reached the first preset temperature at this time, and the fabric cleaning machine 100 can be used for cleaning operations. After the user triggers the switch 34, after the controller 31 receives the control signal sent from the switch 34, it sends a start signal to the water pump 22 to control the water pump 22 to start. Thus, the water pump 22 starts to pump water, and the clean water in the clean water tank 21 is input into the heating boiler 23. The heating boiler 23 generates hot steam and transports the hot steam to the steam nozzle 11 on the cleaning head 10 through the steam pipeline 25. The user can hold the cleaning head 10 to spray steam on the fabric. When the normally closed thermostat detects that the temperature of the heating boiler 23 reaches the second preset temperature (such as 110 °C), the normally closed thermostat disconnects, and the second circuit 37 is immediately disconnected. At this time, the heating boiler 23 stops heating.

[0033] Since the indicator light lights up when the heating boiler 23 is heated to the first preset temperature, reminding the user that the fabric cleaning machine 100 can be used. When the user briefly turns off the fabric cleaning machine 100 and then starts the fabric cleaning machine 100 again, since the heating boiler 23 is already at a relatively high temperature (such as greater than or equal to the first preset temperature), the indicator light remains lit, and the user can directly use the fabric cleaning machine 100, saving waiting time and bringing convenience to the user in operation.

[0034] When the heating boiler 23 is heated to the second preset temperature greater than the first preset temperature, the heating boiler 23 stops heating immediately, which can avoid the over-high temperature situation caused by continuous heating of the heating boiler 23, protect the heating boiler 23, be safer and more reliable, and extend the service life of the fabric cleaning machine 100.

[0035] The technical scope of the present invention is not limited to the content in the above specification. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
