Description

TECHNICAL FIELD

[0001] The present application relates to a water-saving control method of a cleaning machine, and also relates to a cleaning machine using the water-saving control method. BACKGROUND

[0002] With the increasing popularization of various cleaning machines such as dishwashers and washing machines, people have put forward higher and higher requirements for the performance of the cleaning machines. For example, the requirement for water consumption is getting higher and higher. In order to save water, a new dishwasher disclosed in Chinese patent application CN1207284A (application number 98110810.5) is provided with a second washing program after the first washing, so as to save water and washing agent. In fact, the essence of the dishwasher is to prolong the cleaning time of the first washing, so as to save water. However, it is difficult to guarantee good cleaning effect when using the dirty water after the first washing to continue cleaning, and subsequent cleaning work is still needed after draining the water. SUMMARY

[0003] The first technical problem to be solved by the present application is to provide a water-saving control method of a cleaning machine, which can truly realize water saving and facilitate the cleaning degree of the next cleaning without changing the cleaning sequence and affecting the cleaning effect.

[0004] The second technical problem to be solved by the present application is to provide a cleaning machine using the water-saving control method of the aforementioned cleaning machine.

[0005] The technical solution adopted by the present application to solve the first technical problem is: a water-saving control method of a cleaning machine, characterized in that: a foaming work is performed in a cleaning work, and the foam generated by the foaming work is left in a cleaning cavity of the cleaning machine for use in a next cleaning work.

[0006] In order to ensure that as much foam as possible is left, the foaming work is performed in a later stage of the cleaning work.

[0007] Preferably, the foaming work is started at a first set time S before the end of the cleaning work and is ended with the end of the cleaning work.

[0008] Preferably, the first set time S satisfies: 2min≤S≤8min.

[0009] Preferably, S=5min.

[0010] In order to perform the foaming work in a temperature range corresponding to the peak value of the bubble force and improve the foaming effect, the water temperature in the cleaning cavity is controlled to be a set temperature T or in a set temperature range when the foaming work is performed.

[0011] Preferably, the temperature T satisfies: 55℃≤T≤62℃.

[0012] Alternatively, T=58℃ or T=61℃.

[0013] In order to convert the foam into cleaning liquid as much as possible for use, during the next cleaning process, water with a temperature lower than the current cavity temperature is introduced, so that the remaining bubbles in the cleaning cavity break due to the change in pressure caused by the cold and are re-converted into liquid for cleaning use.

[0014] In order to improve the foaming effect and also improve the cleaning ability of the next cleaning process, the foaming work is performed during the cleaning agent use process of the cleaning work.

[0015] As an improvement, the foaming work method comprises the following steps:

[0016] S1, control the water pump for circulating water pumping to rotate at the highest speed;

[0017] S2, control the water temperature inside the cleaning cavity at the temperature state corresponding to the peak value of the bubble force;

[0018] S3, control the water pump to alternately start and stop, and then generate a bubble blowing effect at the position of the draining plate of the cleaning cavity.

[0019] The technical scheme adopted by the present application to solve the second technical problem is: a cleaning machine comprising a control circuit board and a memory, the control circuit board and the memory are electrically connected, characterized in that: the memory stores a program for realizing the water-saving control method of the cleaning machine as described above, and the control circuit board can read and execute the program in the memory.

[0020] Compared with the prior art, the advantages of the present application are that: the water-saving control method of the cleaning machine in the present application performs foaming work during the cleaning process, and the foam generated by foaming is used for the next cleaning work. The liquid converted from the foam can reduce the water inflow of the next cleaning work, thereby achieving the purpose of water saving. Especially when the foam contains washing components, it can also help to improve the cleaning cleanliness of the next cleaning work.

[0021] The cleaning machine using the water-saving control method has low pollution degree and small proportion of foam relative to the cleaning water amount, which does not affect the cleanliness of the next cleaning, and has good water saving effect in long-term use, and also does not affect the normal cleaning program. BRIEF DESCRIPTION OF DRAWINGS

[0022] Figure 1 The working flowchart of the water-saving control method of the cleaning machine in the embodiment of the present application. DETAILED DESCRIPTION

[0023] The application will be further described in detail below with reference to the embodiments of the drawings.

[0024] As Figure 1 shown, the water saving control method of the cleaning machine in the embodiment carries out foaming work in one cleaning work, and a large amount of foam is generated in the foaming work. After the one cleaning work ends and the water is drained, the water in the cleaning cavity of the cleaning machine is drained. Since the foam is adsorbed on the inner wall of the cleaning cavity and cannot be converted into liquid and drained in a short time, most of the foam remains in the cleaning cavity of the cleaning machine. That is, the foam generated in the foaming work remains in the cleaning cavity of the cleaning machine, and can be used for the next cleaning work. The cleaning work in which the foaming work is specifically carried out is specifically which cleaning work in the cleaning process, and is specifically determined according to different cleaning modes.

[0025] In order to ensure that as much foam as possible is retained, the foaming work is carried out in the later stage of the one cleaning work. Specifically, the foaming work is started at a first set time S before the end of the cleaning work and ends when the one cleaning work ends. The first set time S is specifically determined according to the structure parameters of the cleaning machine itself and the working parameters corresponding to the current cleaning program. In the embodiment, the first set time S satisfies 2min≤S≤8min. Preferably, S=5min. That is, the foaming work is started 5min before the end of the current cleaning work, and a large amount of foam is generated in the cavity for use in the next cleaning work.

[0026] In the cleaning cavity, the substances that are easy to generate foam usually include protein, starch and other dirt remaining on tableware, and cleaning agent added in the cleaning cavity. Therefore, in order to improve the foaming effect and also improve the cleaning ability of the next cleaning work, the foaming work is carried out in the process of the one cleaning work using the cleaning agent. On the one hand, after the one cleaning work using the cleaning agent, there must be a rinsing cleaning process to meet the program requirements. On the other hand, the foam formed based on the cleaning agent can be dissolved in the new incoming water in the next cleaning work, further improving the cleaning ability of the cleaning object.

[0027] In addition, the foaming substances are different in foaming power at different temperatures, so if the water temperature in the cleaning cavity can be controlled at the temperature at which the foaming power reaches the peak when the foaming work is performed, the foaming effect can be greatly improved. Therefore, in this embodiment, in order to perform the foaming work in the temperature range corresponding to the peak of the foaming power and improve the foaming effect, the water temperature in the cleaning cavity is controlled to be a set temperature T or in a set temperature range when the foaming work is performed. When the set temperature is selected to be a specific set temperature, the set temperature T preferably satisfies 55℃≤T≤62℃. For example, T=58℃ or T=61℃ can be set. When the set temperature is selected to be a temperature range, the water temperature can have a certain fluctuation, and the water temperature control is easier. In this case, the set temperature range can be selected to be 55℃-62℃. Based on the control of the water temperature in the cleaning cavity, the foaming power of the foaming substance reaches the peak when the foaming work is performed, the foam is generated to the maximum extent, and water can be saved for the next cleaning work.

[0028] Generally, the water amount used for each cleaning work is a set value, and a water level sensor is usually arranged in the cleaning cavity to detect whether the water level in the cleaning cavity reaches the set value. In order to convert the foam into cleaning liquid as much as possible and reduce the water amount for the next cleaning work, water with a temperature lower than the current cavity temperature is introduced into the cleaning cavity, so that the bubbles remaining in the cleaning cavity break due to the change in pressure caused by the cold and are converted into liquid for cleaning.

[0029] In addition, the foaming work method in this embodiment specifically includes the following steps:

[0030] S1, control the water pump for circulating water pumping to rotate at the highest speed, on the one hand, the high-speed rotation of the water pump can drive the spray arm to stir, and the water in the cleaning cavity can generate foam based on mechanical stirring; on the other hand, the high-speed rotation of the water pump can enhance the water pumping capacity of the water pump and improve the slag collecting effect, so that the particulate residues in the cleaning cavity are collected and adsorbed in the slag basket, and the foam generated by too many particulate residues is reduced;

[0031] S2, the water temperature in the cleaning cavity is controlled at the temperature state corresponding to the peak of the foaming power, so as to provide an environmental basis for improving the foaming effect;

[0032] S3, when the foaming amount in the cleaning cavity approaches saturation, the water pump is controlled to alternately start and stop, so that the water pump generates the process of water pumping-stopping-water pumping-stopping. Under the action of the small mesh holes of the draining plate, the "blowing bubble" effect is generated, that is, the blowing bubble effect is generated at the position of the draining plate of the cleaning cavity, and the foaming effect is improved.

[0033] The water-saving control method of the cleaning machine in the application carries out foaming work in the cleaning process, and the foam generated by foaming is used for the next cleaning work. The water inflow of the next cleaning work can be reduced by relying on the liquid converted by the foam, so as to achieve the purpose of water saving. Especially when the foam contains washing components, it is also beneficial to the cleaning cleanliness of the next cleaning work.

[0034] The application also relates to a cleaning machine. The cleaning machine can adopt the existing cleaning machine structure, such as all the cleaning machines currently applied for patent by the applicant. For example, the cleaning machine disclosed in the Chinese Utility Model with the authorized announcement number CN212346455U, namely the cleaning machine with the integrated power and residue discharge structure, can be adopted. The motor in the water pump is rotated to realize the bubble work. The cleaning machine also comprises a control circuit board and a memory, the control circuit board and the memory are electrically connected, the memory stores the program for realizing the water-saving control method of the cleaning machine as described above, and the control circuit board can read and execute the program in the memory. The cleaning machine applying the water-saving control method as described above has low pollution degree of the foam generated by foaming, small proportion relative to the cleaning water, does not affect the cleanliness of the next cleaning, has good water-saving effect in the long-term use, and also does not affect the normal cleaning program.
