Description

Technical Field

[0001] The present application relates to the field of washing machines, and in particular to a water inlet system and control method of a multi-barrel washing machine. Background Art

[0002] As people's quality of life improves and their health awareness grows, more and more people are washing their clothes separately. Currently, most washing machines on the market only have a single drum, and the washing conditions of single-drum washing machines are difficult to meet users' health requirements. Buying two or more washing machines for separate washing not only wastes a lot of energy and water resources, but also takes up a lot of space, making it unsuitable for home use. Therefore, using a multi-drum washing machine can meet people's health needs while saving resources such as water and space.

[0003] In order to ensure the water flow rate, the multi-drum washing machines on the market are all filled with water in sequence or alternately, and cannot be filled with water at the same time. This will cause one drum to be filled with water while the other drum can only start filling with water after the first drum has finished filling with water. Summary of the Invention

[0004] The present invention aims to solve the problem of water inflow in a multi-drum washing machine in the prior art.

[0005] In one aspect of the present application, a method for controlling wash water inlet of a multi-tub washing machine is provided. The multi-tub washing machine includes a first washing tub and a second washing tub, and the first washing tub and the second washing tub share a water inlet system. The method for controlling wash water inlet includes:

[0006] In response to a water inlet instruction of the first washing tub, determining whether the second washing tub is being filled with water;

[0007] If it is determined that the second washing tub is filling with water, determining whether the current water level of the second washing tub has reached the heating safety water level of the second washing tub;

[0008] If it is determined that the current water level of the second washing tub has reached the heating safety water level of the second washing tub, water is controlled to be supplied to the second washing tub at a small flow rate and to the first washing tub at a large flow rate until the water inflow into the first washing tub reaches the heating safety water level of the first washing tub.

[0009] As a further example, if it is determined that the current water level in the second washing tub has not reached the heating safety water level of the second washing tub, water is controlled to be fed into the second washing tub at a high flow rate and water is fed into the first washing tub at a low flow rate until the water inflow into the second washing tub reaches the heating safety water level of the second washing tub;

[0010] The water is controlled to flow into the second washing tub at a small flow rate and into the first washing tub at a large flow rate until the water flow into the first washing tub reaches the heating safety water level of the first washing tub.

[0011] As a further example, if the first washing tub and the second washing tub both reach their respective heating safety water levels but do not reach their respective preset target water levels, the water inlet control method further includes:

[0012] The first washing tub and the second washing tub are controlled to continue to be filled with water according to a preset rule.

[0013] As a further example, the controlling the continued water inflow into the first washing tub and the second washing tub according to a preset rule includes:

[0014] comparing the laundry load weights of the first wash tub and the second wash tub;

[0015] The water is controlled to flow into the washing tub with a large load of clothes at a large flow rate, and to flow into the washing tub with a small load of clothes at a small flow rate.

[0016] Further examples are optional,

[0017] When the water flow into one of the washing tubs reaches its preset target water level, the water flow into the washing tub is stopped, and water is flowed into the washing tub that has not reached the preset target water level at a high flow rate.

[0018] As a further example, the controlling the continued water inflow into the first washing tub and the second washing tub according to a preset rule includes:

[0019] Determine whether the user has set a priority washing rule;

[0020] If so, water is first added to the washing tub that needs to be washed first according to the priority washing rule set by the user until the washing tub reaches the preset target water level.

[0021] As a further example, if the user does not set a priority washing rule, controlling the continued filling of water into the first washing tub and the second washing tub according to the preset rule includes:

[0022] respectively obtain the remaining washing time of the first washing tub and the second washing tub;

[0023] The water is controlled to flow into the washing tub with a longer remaining washing time at a large flow rate and into the washing tub with a shorter remaining washing time at a small flow rate until the water in the washing tub with a longer remaining washing time reaches a preset target water level.

[0024] As a further example, if the user does not set a priority washing rule, controlling the continued filling of water into the first washing tub and the second washing tub according to the preset rule includes:

[0025] respectively obtain the remaining washing time of the first washing tub and the second washing tub;

[0026] The difference between the remaining wash time of the first washing tub and the remaining wash time of the second washing tub is calculated. If the difference is greater than the remaining wash time of the washing tub with the shorter remaining wash time, water is added to the washing tub with the shorter remaining wash time at a large flow rate, and water is added to the washing tub with the longer remaining wash time at a small flow rate until the water in the washing tub with the shorter remaining wash time reaches its preset target water level.

[0027] As a further example, if it is determined that water is flowing into the second washing tub, determining whether the current water level of the second washing tub has reached a safe water level for heating the second washing tub includes:

[0028] determining whether the washing mode of the second washing tub is a heating washing mode;

[0029] If it is determined that the second washing tub is performing water intake in the heating washing mode, it is determined whether the current water level of the second washing tub has reached the heating safety water level of the second washing tub.

[0030] As a further example, if it is determined that the washing mode of the second washing tub is the immersion washing mode, water is controlled to be supplied to the second washing tub at a large flow rate and to the first washing tub at a small flow rate until the water level in the second washing tub reaches a preset target water level; if it is determined that the water is supplied to the second washing tub in the quick washing mode, water is controlled to be supplied to the second washing tub at a large flow rate and to the first washing tub at a small flow rate until the water level in the second washing tub reaches the preset target water level.

[0031] As a further example, the water inlet system is optionally provided with a first water inlet valve assembly for controlling water inlet to the first washing tub and a second water inlet valve assembly for controlling water inlet to the second washing tub, the first water inlet valve assembly including a first main water inlet valve and a first auxiliary water inlet valve connected to the water inlet system to control water inlet to the first washing tub, and the first water inlet valve assembly including a second main water inlet valve and a second auxiliary water inlet valve connected to the water inlet system to control water inlet to the second washing tub; wherein the first main water inlet valve and the second main water inlet valve are large-flow valves, and the first auxiliary water inlet valve and the second inlet valve are small-flow valves;

[0032] If the water is fed into the first washing tub at a high flow rate, the first main water inlet valve is activated to feed water. If the water is fed into the first washing tub at a low flow rate, the first auxiliary water inlet valve is activated to feed water.

[0033] If water is controlled to flow into the second washing tub at a large flow rate, the second main water inlet valve is activated to allow water to flow in. If water is controlled to flow into the second washing tub at a small flow rate, the second auxiliary water inlet valve is activated to allow water to flow in.

[0034] Another aspect of the present invention provides an electronic device, the electronic device comprising:

[0035] a memory for storing one or more computer instructions;

[0036] A processor is configured to retrieve and execute the computer instructions from the storage to implement any of the methods described above.

[0037] Another aspect of the present invention provides a multi-tub washing machine, which includes a control device, and the control device implements any of the above-mentioned washing water inlet control methods.

[0038] The water inlet control method provided in the present application can ensure that the working processes of multiple washing drums of a multi-drum washing machine are reasonably arranged when one drum is about to be filled with water and another drum is currently being filled with water, thereby solving the problem of long waiting time when one drum of a multi-drum washing machine is about to be filled with water and another drum is currently being filled with water.

[0041] Figure 2 is another flowchart provided according to an embodiment of the present invention. DETAILED DESCRIPTION

[0042] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0043] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0044] The water inlet mentioned in this application document is water in a broad sense, including the first water inlet of the washing program and the water replenishment during the washing process.

[0045] The first washing tub and the second washing tub mentioned in this application do not have specific meanings and are merely used to distinguish the two washing tubs for convenience. When the second washing tub receives a water inlet command, the water inlet control of this application also follows the same control logic as the inventive concept.

[0046] The small flow rate and large flow rate expressed in this application document represent the relative water inlet flow rate relationship of different washing tubs based on the same water inlet system, rather than their respective absolute water inlet flow rates.

[0047] Example 1

[0048] According to an embodiment of the present application, an embodiment of a washing water inlet control method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0049] According to an embodiment of the present application, the present invention provides a multi-tub washing machine embodiment comprising a first washing tub ( Figure 2 The first bucket in Chinese) and the second washing bucket ( Figure 2 The first and second washing tubs share a common water inlet system (the water inlet system is not shown). The water inlet system is respectively equipped with a first water inlet valve assembly for controlling water inlet to the first washing tub and a second water inlet valve assembly for controlling water inlet to the second washing tub. The first water inlet valve assembly includes a first main water inlet valve and a first auxiliary water inlet valve connected to the water inlet system to control water inlet to the first washing tub, while the first water inlet valve assembly includes a second main water inlet valve and a second auxiliary water inlet valve connected to the water inlet system to control water inlet to the second washing tub. Both the first and second main water inlet valves are high-flow valves, while both the first and second auxiliary water inlet valves are low-flow valves. If water is controlled to be fed into the first washing tub at a high flow rate, the first main water inlet valve is started to feed water alone or together with the first auxiliary water inlet valve; if water is controlled to be fed into the first washing tub at a low flow rate, the first auxiliary water inlet valve is started to feed water; if water is controlled to be fed into the second washing tub at a high flow rate, the second main water inlet valve is started to feed water alone or together with the second auxiliary water inlet valve; if water is controlled to be fed into the second washing tub at a low flow rate, the second auxiliary water inlet valve is started to feed water.

[0050] Of course, the next best option is to set a valve in each washing tub, which can adjust the flow rate. However, such a valve setting involves constant adjustment of the valve, which is not conducive to the long-term use of the valve and the guarantee of water inflow.

[0051] As attached Figure 1-2 The washing water inlet control method provided in this embodiment includes the following steps:

[0052] 101: In response to a water inlet instruction of the first washing tub, determine whether the second washing tub is being filled with water.

[0053] When the first washing drum of the multi-drum washing machine of the present invention reaches the water filling program, it is necessary to determine whether another washing drum is filling with water or replenishing water, so as to reasonably arrange the working processes of multiple washing drums and solve the problem of long waiting time when one drum of the multi-drum washing machine is about to fill with water and another drum is filling with water.

[0054] If it is determined that the second washing tub has no water, the first tub will simultaneously start the high-flow water inlet and the low-flow water inlet to quickly complete the water filling.

[0055] The water inlet here refers to water in a broad sense, including the first water inlet of the washing program and water replenishment during the washing process; the first washing tub and the second washing tub referred to here do not have specific meanings, but are only used to distinguish the two washing tubs for the convenience of expression.

[0056] 102: If it is determined that the second washing tub is being filled with water, it is determined whether the current water level of the second washing tub has reached the heating safety water level of the second washing tub.

[0057] The heating safety water level here refers to the minimum safe water level for heated washing. This application uses the heating safety water level as one of the control factors, not only considering that the waiting time for water inlet should not be too long, but also considering the safety of washing, especially when the consumers are elderly or children who are not familiar with washing operations.

[0058] Of course, not all washing programs are heated washing. Even if the second washing machine drum does not perform a heated washing program, using the minimum safe water level for heated washing as a control factor for controlling the water inlet method of the second washing drum is very beneficial for dual protection of washing time and washing safety.

[0059] As an optional embodiment, if it is determined that the second washing tub is filling with water, the washing mode of the second washing tub may be determined first, and then the water filling of the first washing tub and the second washing tub may be determined based on the washing mode of the second washing tub. If the washing mode of the second washing tub is not a heating washing mode, the heating safety water level may not be determined. For example:

[0060] If the second washing tub is determined to be in soak mode, water can be added to the second tub at a high flow rate and to the first tub at a low flow rate until the water level in the second tub reaches the preset target level. This is because soaking generally takes a long time, so the second tub can be allowed to reach the preset target level first to avoid wasting time and thus wasting time.

[0061] In another scenario, if the second washing tub is determined to be in quick wash mode, water can be initially supplied to the second washing tub at a high flow rate, followed by a low flow rate to the first washing tub, until the water level in the second washing tub reaches the preset target level. This control is based on the fact that quick washes generally have shorter wash times, allowing the shorter wash cycle to complete first, thus preventing the shorter wash cycle from waiting too long for water to be supplied, ultimately failing to achieve the desired quick wash.

[0062] 103: If it is determined that the current water level of the second washing tub has reached the heating safety water level of the second washing tub, control the water to flow into the second washing tub at a small flow rate and control the water to flow into the first washing tub at a large flow rate until the water flow into the first washing tub reaches the heating safety water level of the first washing tub.

[0063] The small flow rate and large flow rate described in this application express the relative water inlet flow rate relationship between the first washing tub and the second washing tub, rather than the absolute water inlet flow rate of each of the first washing tub and the second washing tub.

[0064] If the heating safety water level in this application is lower than the target preset water level and the second washing tub is still filling, it indicates that it has not yet reached the preset target water level (corresponding to the preset target water level for various wash programs). Controlling the water flow to the second washing tub at a low flow rate can synchronize the water flow to both washing tubs, avoiding excessive waiting time for the second washing tub to fill, while also eliminating the need to completely stop the water flow to the second washing tub, allowing the wash program to continue uninterrupted. If the water flow to the second washing tub stops when it reaches the preset target water level, or if the first washing tub's load requires a larger water flow or the user has set the first washing tub to fill first, the water flow to the second washing tub can be paused until the first washing tub reaches the heating safety water level.

[0065] Regardless of the above situation, if one bucket has finished filling with water and the other bucket still needs to be filled with water, the large flow valve and the small flow valve of the other bucket can be opened at the same time to quickly complete the water filling.

[0066] 104: When the second washing tub and the first washing tub both reach the heating safety water level, the first washing tub and the second washing tub are controlled to continue to fill with water according to a preset rule.

[0067] It should be noted that the second washing tub and the first washing tub may be provided with respective heating safety water levels. This application does not require the two heating safety water levels to be the same, nor does it require the preset target water levels of the two to be the same.

[0068] 104-1 is one of the optional implementation methods. The preset rule can be to select the water filling method according to the user priority principle. For example, if the user sets the priority washing rule, it is necessary to fill the washing bucket that needs to complete the washing first with a large flow rate according to the priority washing rule set by the user until the washing bucket reaches the preset target water level.

[0069] The specific control logic may include the following:

[0070] Determine whether the user has set a priority washing rule;

[0071] If so, water is first added to the washing tub that needs to be washed first at a large flow rate according to the priority washing rule set by the user until the washing tub reaches the preset target water level.

[0072] If not, the first and second washing tubs are controlled to continue to be filled with water according to the laundry load weight.

[0073] 104-2 As another optional implementation, the preset rule may be to control the continued water inflow into the second washing tub and the first washing tub according to the weight of the laundry load.

[0074] (1) Considering that the laundry load is heavy and the washing time is long, one of the optional embodiments for controlling the continued water inflow into the second washing tub and the first washing tub according to the laundry load weight includes the following control steps:

[0075] comparing the laundry load weights of the first wash tub and the second wash tub;

[0076] Water is added to the washing tub with a larger load weight at a higher flow rate, and to the washing tub with a smaller load weight at a lower flow rate, until both washing tubs reach a preset target water level. When the water inflow into a washing tub reaches its preset target water level, water inflow into the washing tub is stopped, and water is added to the washing tub that has not reached the preset target water level at a higher flow rate.

[0077] (2) Considering the common situation where the load is small and the washing needs to be completed quickly, as a second optional embodiment of controlling the continued water supply to the second washing tub and the first washing tub according to the remaining washing time of the two washing tubs, after obtaining the comparison result of the clothing load weight of the first washing tub and the second washing tub, water can be supplied to the washing tub with the smaller clothing load weight at a large flow rate, and water can be supplied to the washing tub with the smaller clothing load weight at a large flow rate, so that the washing tub with the smaller load can complete the washing quickly.

[0078] 104-3 As another optional implementation, the preset rule may be to control the continued water inflow into the second washing tub and the first washing tub according to the remaining washing time of the two washing tubs.

[0079] (1) As one of the optional embodiments for controlling the continued water inflow into the second washing tub and the first washing tub according to the remaining washing time of the two washing tubs, the specific control steps include:

[0080] Obtaining the remaining washing time of the first washing tub and the second washing tub;

[0081] Fill the washing tub with a large flow rate for the remaining washing time and fill the washing tub with a small flow rate for the remaining washing time;

[0082] When the water flow into one of the washing tubs reaches the preset target water level first, the water flow into the washing tub is stopped, and water is flowed into the washing tub that has not reached the preset target water level at a high flow rate;

[0083] Until both washing tubs reach the preset target water level.

[0084] (2) As a second optional embodiment for controlling the continued water inflow into the second washing tub and the first washing tub according to the remaining washing time of the two washing tubs, the specific control steps include:

[0085] Obtaining the remaining washing time of the first washing tub and the second washing tub;

[0086] The difference between the remaining wash times of the first and second washing tubs is calculated. If the difference is greater than the minimum of the remaining wash times, water is added at a low flow rate to the washing tub with the longer remaining wash time, and at a high flow rate to the washing tub with the shorter remaining wash time. When the water flow in one washing tub reaches a preset target water level first, water flow is stopped in that washing tub, and water is added at a high flow rate to the washing tub that has not reached the preset target water level; this continues until both washing tubs reach the preset target water level.

[0087] The control logic of this embodiment is to avoid the washing that can be completed in a short time from having to wait too long for water to enter, thereby losing the meaning of quick washing.

[0088] It should be noted that: regardless of the above situation, if one bucket has finished filling with water and the other bucket still needs to fill with water, the other bucket can open the large flow valve and the small flow valve at the same time to quickly complete the water filling. The so-called large flow water filling can be water filling with a large flow valve or water filling with a large flow valve and a small flow valve together. Preferably, when only one bucket is filling with water, the large flow valve and the small flow valve of the bucket are opened together. When there are two buckets filling with water, only the large flow valve of the bucket with large flow water filling is opened. As shown in the attached figure Figure 2 This is the case when the high flow valve of the illustrated embodiment is opened.
