Abstract
Description
- The present disclosure relates to a technical field of design and manufacture of washing machines, in particular relates to a multi-drum washing machine and a control method therefor.
- An ordinary drum washing machine is a single-drum washing machine. In order to meet the requirements of washing all the family clothes, a washing machine with a large capacity, such as a large washing machine over 6 kg, is generally selected by a family. With the progress of the times and the improvement of people's living standards, the pace of life is getting faster and faster. Then, many problems occur in the use of the above-mentioned washing machines. For example, clothes may be divided into adult clothes, underwear and children's clothes. The washing machines are used for several times just for performing separated washings, which requires a lot of washing time and consumes a lot of energy. When the energy saving is taken into account, the washing process set in a large washing machine generally consumes a large amount of water and a large amount of electricity as well. When a small amount of laundry is washed, a large washing machine generally is not a good choice, and at the same time, the washing time is relatively long due to the large amount of laundry expected during the washing process. In addition, the washing process set by the large washing machine is expected to be mainly general clothes, and may not be suitable for washing fine clothes such as underwear or children's clothing, etc.
- In order to solve the above problems, a double-drum washing machine has been developed in a related art. Such a double-drum washing machine has a large-capacity washing drum and a small-capacity washing drum that are driven individually or simultaneously, and performs separate washing operations in each drum. It is as if that the user should use two drum washing machines with different capacities at the same time, without occupying additional physical space. It is possible to flexibly perform washings simultaneously or separately according to the washing amount and the type of washing clothes.
- However, in the related art, for the above-mentioned double-drum washing machine, independent input control unit and independent output display unit are usually configured for each washing tub. The control system is simply superimposed on the hardware, and is still essentially two separate control systems. It indirectly leads to higher manufacturing costs, hinders the promotion and application in the market, and it is also to the disadvantage of the upgrade and maintenance of the control system in a later period.
- The present disclosure provides a multi-drum washing machine and a control method therefor to solve the problem of controlling each washing dram of the multi-drum washing machine so as to reduce the manufacturing cost of the multi-drum washing machine.
- Embodiments of the present disclosure provide a multi-drum washing machine, including:
- at least two separate washing drums, a control panel, an integrated circuit (IC) controller, and a driving circuit board,
- the control panel has a plurality of input control elements and a plurality of output display elements, the input control elements are configured for inputting laundry parameters, and the output display elements are configured for displaying states in a washing process, and
- the IC controller and the driving circuit board are connected to the control panel and control the operation of the washing drums.
- In one embodiment, the plurality of washing drums share a part or all of the input control elements and the output display elements, and shared input control elements and/or shared output display elements uniquely correspond to an operating program of one of the washing drums by selecting one of the washing drums at the time of operation and serve as input elements or output elements of one of the washing drums.
- In one embodiment, a selection switch is disposed on the control panel for designating one of the washing drums.
- In one embodiment, the switch is a button or a rotary knob.
- In one embodiment, a plurality of the washing drums have respective separate output display elements, and only the input control elements are shared.
- In one embodiment, the plurality of the washing drums have respective separate input control elements, and only the output display elements are shared.
- In one embodiment, the plurality of the washing drums share the input control elements and the output display elements.
- In one embodiment, the control panel has a power switch served as a total control power switch.
- In one embodiment, the input control element and the output display element are a same button.
- The embodiments of the present disclosure also provides a control method of a multi-drum washing machine, which adopts the multi-drum washing machine provided by any one embodiment of the present disclosure, and the method includes:
- acquiring a selection instruction of a corresponding washing drum by a washing machine, retrieving a background control program of the washing drum and enabling the shared input control elements and/or the shared output display elements to uniquely correspond to the operating program of one of the washing drums and serve as input elements or output elements of the one of the washing drums.
- In one embodiment, when the background control program of the washing drum is retrieved, only the input control elements are used as input elements.
- In one embodiment, when the background control program of the washing drum is retrieved, only the output control elements are used as output elements.
- Regarding the multi-drum washing machine and the control method therefor provided by the embodiments of the present disclosure, input control elements and output display elements are provided on the control panel. During uses, a plurality of washing drums share all or a part of the input control elements and the output display elements. By selecting a specific washing drum, the corresponding washing program is retrieved, and the above-mentioned input control elements and/or output display elements are associated with the washing program as a corresponding input and output of one of the washing drums so that operations and controls of a plurality of washing drums are incorporated with a set of control systems. It replaces a superposition of simple hardware in the past, and reduces the number of the input control units and the output display units in the control panel of the multi-washing drum washing machine, thereby simplifying the hardware structure of the control panel, reducing the cost of the hardware of the washing machine and contributing to the later upgrade and maintenance of the control system.

- The present disclosure will be described in detail below in combination with alternative embodiments and drawings. It should be understood that, the alternative embodiments described herein are merely for purposes of explaining the present disclosure and are not intended to limit the present disclosure. In addition, for ease of description, only some of the details related to the present disclosure are shown in the drawings instead of the whole contents. The features in the embodiments and the embodiments may be combined with each other arbitrarily without conflicts.
- As shown in
FIG. 1 , a schematic diagram of the appearance of a double-drum washing machine is provided. The washing machine is equipped with anupper drum 1 and alower drum 2 in a machine body to form a pair of separate washing drums, and has acontrol panel 3 at the same time. In practical productions, the capacity of theupper drum 1 is usually designed to be small, generally 2-3 kg, and the capacity of thelower drum 2 is designed to be large, generally 6-8 kg, which is also beneficial to lower of the overall washing machine's center of gravity. In operations, two separate washing drums can be operated separately or simultaneously. For a user, it is as if that there should be two drum washing machines with different capacities at the same time, and there are more choices when the user faces various washing conditions at home. For example, the upper drum can be used for the fine washing of single or small batches of clothes, and the lower drum can be used for washing large items of clothing, such as the cleaning of bed sheets. More importantly, the two batches of washing can be performed simultaneously, and the waiting time can be reduced. From the aspect of actual use effect, it provides the advantages of saving time and energy. - Since the above-mentioned drum washing machine involves the control of two independent washing drums (the upper and lower washing drums), it is objectively necessary to provide two sets of input control units and output display units respectively correspond to each of the two independent washing drums on the
control panel 3 to cooperate with the user to perform input settings and status display for each of the two independent washing drums, and the composition of the control system of the double-drum washing machine is shown inFIG. 2 . The user performs settings of a variety of laundry parameters and programs through the control panel. The IC controller performs a communication connection with the control panel, the input parameter of the control panel is received, a selected program is inputted, and instructions are sent to the driving circuit. According to the instructions, the driving circuit drives the corresponding operations of the upper drum or the lower drum, and the corresponding IC controller transmits the working state parameters of the corresponding drum in real time to the control panel for a real-time display, so as to facilitate the user's control over a washing process. - Regarding a control process of the double-drum washing machine, the control panel provided by embodiments of the present disclosure may adopt structures shown in
FIGS. 3 to 5 . The areas in the control panel can be divided into aninput control unit 4, anoutput display unit switching unit 7. Theinput control unit 4 is composed of six buttons of “temperature”, “rotation speed”, “wash”, “rinse”, “reserve” and “clean”, asinput control elements 9, and all the input control elements in theinput control unit 4 are taken as common parts of the upper and lower drums. Accordingly, theoutput display unit 5 is also composed of a plurality ofoutput display elements 10, which respectively correspond to the displays of the selected parameters at the time of inputting the input control elements of the upper drum as “temperature”, “rotation speed”, “wash”, “rinse”, “reserve” and “clean”. At the same time, theoutput display unit 6 is also composed of a plurality of output display elements, which respectively correspond to the displays of the selected parameters at the time of inputting the input control elements of lower drum as “temperature”, “rotation speed”, “wash”, “rinse”, “reserve” and “clean”. During operations, the corresponding upper or lower drum is selected by the selection of theswitching unit 7. As shown inFIG. 3 , at this time, the upper drum is selected, shared input control elements uniquely correspond to the operating procedure of the upper drum, and the IC controller transfers the above-mentioned input parameters to the corresponding operation program. At this time, sharedcontrol elements 9 are merely used as the input of a control program the upper drum, and the output display units of the corresponding upper and lower drums are independent, e.g. the “rotation speed” is 900 rpm for the upper drum and 1000 rpm for the lower drum; and the “washing” is 30 minutes for the upper drum and 20 minutes for the lower drum. This enables the real-time status of the operation of the washing machine to be more visible. - Another option of the structure of the control panel is shown in
FIG. 6 . The area of the control panel is divided into aninput control unit 4 and anoutput display unit 5. In this example, the correspondingoutput display unit 5 is formed by a plurality ofoutput display elements 10, which are served as common output display elements. There are twoinput control units 4 to respectively correspond to the upper drum and the lower drum. Eachinput control unit 4 is formed by six buttons marked with “temperature”, “rotation speed”, “wash”, “rinse”, “reserve” and “clean” as theinput control elements 9, and each of the six buttons corresponds to the input control elements of control programs of the upper and lower drum. During operations, the corresponding upper or lower drum is selected by the selection of theswitching unit 7. As shown inFIG. 6 , the upper drum is selected at this time, and the common output display elements uniquely correspond to the operating procedure of the upper drum. The IC controller outputs the status parameters of the upper drum in real-time through the above display elements. As shown in the figure, the upper drum has a “temperature” of 60° C., a “rotation speed” of 800 rpm, a “washing” time of 30 minutes and “rinse” for three times. At this time, the inputs of the upper and lower drums are inputted through separate control elements. - A third option of the structure of the control panel is shown in
FIG. 7 . The area of the control panel is divided into aninput control unit 4 and anoutput display unit 5. In this example, the correspondingoutput display unit 5 is formed by a plurality ofoutput display elements 10, which are served as common output display elements. Theinput control unit 4 is formed by six buttons marked with “temperature”, “rotation speed”, “wash”, “rinse”, “reserve” and “clean” as theinput control elements 9, which are also served as common output display elements. During operations, the corresponding upper or lower drum is selected by the selection of theswitching unit 7. As shown inFIG. 7 , the upper drum is selected at this time, and the common output display elements and the common input control elements uniquely correspond to the operating procedure of the upper drum. The IC controller outputs the status parameters of the upper drum in real-time through the above display elements. As shown in the figure, the upper drum has a “temperature” of 60° C., a “rotation speed” of 800 rpm, a “washing” time of 30 minutes and “rinse” for twice. The advantage of this solution is that the input and output functions necessary for separately controlling the upper and lower drums can be satisfied with merely using a set of common input control elements and common output display elements. - Another advantage of the embodiments of the present disclosure is that, for two or more separate washing drums, no major changes are required for their respective control systems, i.e. only one separate system needs to be maintained during maintenance, which is of practical significance to the later software upgrading of the product, such as the increasing demands of the customers driven by the Internet.
- For the entire control panel, since there is merely one set of control systems, one
power switch 8 can be separately configured as the total power control. Thecorresponding switching unit 7 also can be configured in a variety of external forms. In addition to the commonly used double buttons, a single button can be used for switching. Alternatively, a knob can be used for performing selections and switching. -
FIG. 8 shows a fourth possible selection of the structure of the control panel. As shown in the figure, the rotary knob can be used as a selection switch, a rotation direction serves as the input control elements, and program items on both sides serve as the output display elements. The corresponding input control elements and output display elements are shared, and the washing drum is selected by a selection switch. As shown in the figure, it is used as the output of the lower drum. - In practical use, another case also exists. As shown in
