Description

Technical Field

[0001] The present invention belongs to the technical field of washing equipment, and in particular, relates to a control method for washing equipment and the washing equipment. Background Art

[0002] As the most widely used household appliance in people's daily life, washing equipment helps people get rid of the trouble of washing clothes and brings great convenience to people. However, with the increasing types and functions of washing equipment, while making it more suitable for users' different washing needs, it is difficult to meet users' different requirements for the rinsing rate during the rinsing process, that is, it is difficult to meet users' different requirements for the ability of washing equipment to remove impurities including washing powder and dirt during the rinsing process.

[0003] At present, some existing washing machines determine when to end the rinsing process by a fixed number of executions of the rinsing cycle. This process is difficult to meet the different rinsing rate requirements of users for the rinsing process, and it is difficult to achieve the same ideal rinsing rate for clothes of different types and degrees of dirtiness.

[0004] Another part of washing equipment has a fixed turbidity threshold, and the washing equipment detects turbidity through a photoelectric sensor, a conductivity sensor, etc., and controls the end time of the rinsing process by comparing the turbidity threshold with the turbidity. In this process, the fixed rinsing rate is difficult to meet the needs of users with sensitive skin for a high rinsing rate, and due to the type of clothing and the degree of dirtiness and type of dirtiness of the clothing, there are clothes that will not be rinsed clean no matter how many times they are rinsed, making the fixed rinsing rate too high and difficult to achieve, wasting water and electricity.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a control method and a washing device for a washing device. The washing device provides the user with the function of independently setting the rinsing rate, so that the end timing of the rinsing process can be automatically controlled according to the user's different requirements for the rinsing rate and the turbidity detection of the washing water. While meeting the user's requirements for the rinsing rate, it avoids the user manually setting an excessively long rinsing process in order to achieve a high rinsing rate, thereby achieving water and electricity saving.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] The present invention provides a control method for a washing device, comprising:

[0009] Before the rinsing process of the washing device, obtaining a desired rinsing rate set by a user;

[0010] According to the expected rinsing rate, determining a corresponding turbidity threshold;

[0011] During the rinsing process of the washing device, detecting the turbidity of the washing water in the washing tub;

[0012] The detected turbidity is compared with the turbidity threshold, and it is determined whether to end the rinsing process according to the comparison result.

[0013] The present invention sets a desired rinsing rate set by the user corresponding to a turbidity threshold of the washing water during the rinsing process, and compares the turbidity with the turbidity threshold to determine whether to end the rinsing process, so that the user's different demands for the rinsing rate can be achieved during the rinsing process of the washing device. While meeting the user's demand for the rinsing rate, it avoids the user manually setting an excessively long rinsing process in order to achieve a high rinsing rate, thereby achieving water and electricity saving.

[0014] A further solution of the present invention is that the washing device is provided with at least two rinsing rate gears;

[0015] Obtaining the expected rinse rate set by the user includes: receiving a selection instruction for one of the rinse rate gears, and determining that the rinse rate corresponding to the selected rinse rate gear is the expected rinse rate.

[0016] In the above scheme, by accepting the selection instruction of the rinse rate gear, it is determined that the rinsing rate corresponding to the selected rinse rate gear is the expected rinse rate, so that the user can conveniently set the expected rinse rate.

[0017] A further solution of the present invention is: judging whether to end the rinsing process according to the comparison result, including:

[0018] If the turbidity is less than the turbidity threshold, the rinsing process is ended, otherwise the rinsing process is continued.

[0019] A further solution of the present invention is that: during the rinsing process, at least one rinsing cycle is run, and the rinsing cycle includes performing an operation of draining the washing tub;

[0020] Before the rinse cycle runs to the operation of draining the washing tub, the turbidity of the washing water is detected to obtain a first turbidity. If the first turbidity is less than the turbidity threshold, the rinsing process is terminated after the washing tub draining operation of this rinse cycle is completed, otherwise the next rinse cycle is continued after the washing tub draining operation is performed.

[0021] In the above scheme, by controlling the turbidity of the washing water during the rinsing process, the rinsing process can meet the corresponding rinsing rate value.

[0022] A further solution of the present invention is: counting the number of times the rinsing cycle is run during the current rinsing process;

[0023] If the operation times reaches the upper limit of the operation times, the rinsing process ends after the current rinsing cycle is completed.

[0024] In the above scheme, by setting an upper limit on the number of operations, the user is prevented from setting an unattainable rinsing rate that is too low, thereby further achieving water and energy saving in the rinsing process.

[0025] A further solution of the present invention is: before the rinsing process ends, the turbidity of the washing water is detected to obtain a second turbidity, and the actual rinsing rate of the rinsing process is obtained according to the second turbidity;

[0026] The washing device pushes the actual rinsing rate.

[0027] In the above solution, the user can know the actual rinsing rate of the rinsing process, which facilitates the user to use the washing device.

[0028] A further solution of the present invention is: during the washing process of the washing device, the turbidity of the washing water is continuously detected to obtain the washing turbidity;

[0029] Counting the duration for which the washing turbidity remains stable;

[0030] If the duration reaches the set time, the washing process is ended, otherwise the washing process continues.

[0031] In the above scheme, if the washing turbidity remains stable for a set time, the washing process is terminated, so that when the clothes are no longer dirty during the washing process, the washing device automatically terminates the washing process, thereby realizing the intelligence of the washing device, further facilitating the user's use of the washing device, and saving water and electricity.

[0032] A further solution of the present invention is that the washing device has a washing tub self-cleaning program;

[0033] During the operation of the washing tub self-cleaning program, the washing device detects the turbidity of the washing water to obtain the rinsing turbidity, and determines whether to end the washing tub self-cleaning program according to the rinsing turbidity.

[0034] In the above scheme, by judging whether to end the barrel self-cleaning program according to the rinse turbidity, the barrel self-cleaning program can be automatically and accurately ended, the intelligent washing equipment is realized, the user's use of the washing equipment is further facilitated, and water and electricity are saved.

[0035] The present invention also provides a washing device, wherein the washing device executes the control method of the washing device.

[0036] A further embodiment of the present invention is: a washing device comprising:

[0037] A turbidity detection device, used to detect the turbidity of the washing water in the washing tub;

[0038] An operation panel for obtaining a desired rinse rate set by a user;

[0039] The control system is used to determine the corresponding turbidity threshold according to the expected rinsing rate obtained by the operation panel, and control whether to end the rinsing process according to the comparison result between the detected turbidity and the turbidity threshold.

[0040] In the above scheme, the turbidity detection device and the control system ensure the accurate detection and acquisition of the turbidity of the washing water, and the operation panel facilitates the user to set the desired rinsing rate.

[0041] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0042] 1. The washing equipment provides the user with the function of setting the rinsing rate independently, so that the washing equipment can automatically control the end time of the rinsing process according to the different requirements of the user for the rinsing rate and the turbidity detection of the washing water. While meeting the user's requirements for the rinsing rate, it avoids the user manually setting an excessively long rinsing process in order to achieve a high rinsing rate, thus saving water and electricity;

[0043] 2. If the washing turbidity remains stable for a set time, the washing process is terminated, so that when the clothes are no longer dirty during the washing process, the washing device automatically terminates the washing process, realizing the intelligence of the washing device, further facilitating the use of the washing device by users, and saving water and electricity;

[0044] 3. By judging whether to end the barrel self-cleaning rinsing stage according to the rinsing turbidity, the barrel self-cleaning rinsing stage can be automatically and accurately ended, the intelligent washing equipment is realized, the user's use of the washing equipment is further facilitated, and water and electricity are saved;

[0045] 4. The turbidity detection device and control system ensure accurate detection and acquisition of the turbidity of the washing water. The operation panel facilitates users to set the desired rinse rate.

DETAILED DESCRIPTION

[0055] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0056] like Figures 1 to 5 As shown, a control method and a washing device of the present invention provide a function for users to independently set the rinsing rate through the washing device, so that the end timing of the rinsing process can be automatically controlled according to the different needs of the users for the rinsing rate and the turbidity detection of the washing water. While meeting the needs of the users for the rinsing rate, it avoids the users manually setting an excessively long rinsing process in order to achieve a high rinsing rate, thereby achieving water and electricity saving.

[0057] Embodiment 1

[0058] like Figure 1 and 2As shown, the present embodiment provides a control method for a washing device, comprising: before the rinsing process of the washing device, obtaining an expected rinsing rate set by a user; determining a corresponding turbidity threshold value according to the expected rinsing rate; during the rinsing process of the washing device, detecting the turbidity of washing water in a washing tub; comparing the detected turbidity with the turbidity threshold value, and judging whether to end the rinsing process according to the comparison result.

[0059] In this embodiment, the rinsing rate refers to the removal rate of impurities including washing powder, dirt, etc. by the washing device during the rinsing process.

[0060] Specifically, the washing device is provided with a turbidity detection device 3, through which the turbidity of the washing water in the washing tub is detected. The turbidity detection device 3 communicates with the control system of the washing device, and the control system stores and calculates and analyzes the turbidity.

[0061] More specifically, the turbidity detection device 3 is provided with an infrared pair tube that directly irradiates the washing water in the washing tub, and the infrared light intensity generated by the infrared pair tube passing through the washing water is detected by the receiving end of the infrared pair tube, and a corresponding current magnitude is generated according to the light intensity, and a corresponding electrical signal is generated according to the current magnitude, so that the turbidity of the washing water, that is, the light transmittance of the washing water, can be accurately detected by the turbidity detection device 3. In a specific application of this embodiment, the infrared pair tube is IR958 and PT958 packaged.

[0062] Therefore, by setting the desired rinse rate set by the user corresponding to the turbidity threshold of the washing water during the rinsing process, and comparing the turbidity with the turbidity threshold to determine whether to end the rinsing process, the user's different demands for rinse rates can be met during the rinsing process of the washing equipment, while avoiding the user manually setting an excessively long rinsing process in order to achieve a high rinse rate, thereby saving water and electricity.

[0063] In this embodiment, Figure 2 As shown, the washing device is provided with at least two rinsing rate gears; obtaining the desired rinsing rate set by the user includes: receiving a selection instruction for one of the rinsing rate gears, and determining that the rinsing rate corresponding to the selected rinsing rate gear is the desired rinsing rate.

[0064] Specifically, a rinse rate setting option is set on the operation panel of the washing device, so that the user can set the desired rinse rate while setting other parameters of the washing device, further facilitating the user to use the washing device. The other parameters include setting the washing program, rinsing program, water level, washing time, and intensity.

[0065] In a specific application of this embodiment, three rinsing rate gears with successively increasing rinsing rates are set and are marked as rinse 1, rinse 2, and rinse 3 respectively.

[0066] Therefore, by accepting the selection instruction of the rinse rate gear, it is determined that the rinsing rate corresponding to the selected rinse rate gear is the expected rinse rate, so that the user can conveniently set the expected rinse rate.

[0067] In this embodiment, Figure 2 As shown, judging whether to end the rinsing process according to the comparison result includes: if the turbidity is less than the turbidity threshold, then ending the rinsing process, otherwise continuing the rinsing process.

[0068] In this embodiment, Figure 2 As shown, at least one rinsing cycle is run during the rinsing process, and the rinsing cycle includes executing the operation of draining the washing tub; before the rinsing cycle runs to the operation of draining the washing tub, the turbidity of the washing water is detected to obtain a first turbidity, and if the first turbidity is less than the turbidity threshold, the rinsing process is terminated after the operation of draining the washing tub in this rinsing cycle is completed, otherwise the next rinsing cycle is continued to run after the operation of draining the washing tub is executed.

[0069] Specifically, the rinsing process is a cyclic operation of a fixed-time rinsing cycle, and the rinsing cycle includes water entering the washing tub, performing a rinsing action, and draining the washing tub in sequence. More specifically, the fixed time is 4 minutes, and the turbidity of the washing water is detected 30 seconds before the end of the rinsing cycle to obtain a first turbidity, and then by controlling the number of executions of the rinsing cycle, the overall running time of the rinsing process is controlled without interrupting the original rinsing program of the washing device.

[0070] Therefore, by controlling the turbidity of the washing water during the rinsing process, the rinsing process can meet the desired rinsing rate set by the user.

[0071] In this embodiment, Figure 2 As shown, the washing device also counts the number of times the rinse cycle is run during the current rinse process; if the number of runs reaches the upper limit of the number of runs, the rinse process is ended after the current rinse cycle is completed.

[0072] In a specific application of this embodiment, the upper limit of the number of operations is 5. When the number of operations of the rinsing cycle reaches 5, the detection result of the turbidity of the washing water is ignored, and the rinsing process is directly ended after the current rinsing cycle is completed.

[0073] Therefore, by setting an upper limit on the number of operations, the user is prevented from setting an unattainable rinsing rate that is too low, further achieving water and energy saving in the rinsing process.

[0074] In this embodiment, Figure 2 As shown, before the rinsing process ends, the turbidity of the washing water is detected to obtain a second turbidity, and the actual rinsing rate of the rinsing process is obtained according to the second turbidity; the washing device pushes the actual rinsing rate.

[0075] Specifically, the turbidity interval in which the second turbidity is located is determined, and the actual rinsing rate of the corresponding rinsing process is determined according to the turbidity interval.

[0076] Specifically, if the number of times the rinse cycle is run during this rinsing process reaches the upper limit of the number of times, the turbidity of the washing water is detected to obtain a second turbidity, and the actual rinsing rate of the rinsing process is obtained based on the second turbidity, and the actual rinsing rate is pushed.

[0077] In a specific application of this embodiment, the washing device is an IoT-type washing device. By communicating with a mobile device, the actual rinsing rate or the actual rinsing rate level corresponding to the actual rinsing rate can be notified to the user in the application and / or display page.

[0078] In a specific application of this embodiment, three rinse rate gears with increasing rinse rates are set and are marked as rinse 1, rinse 2, and rinse 3, respectively, and have successively decreasing turbidity thresholds and successively decreasing turbidity intervals. Specifically, the upper limits of the turbidity intervals of the three rinse rate gears are consistent with the turbidity thresholds, so that the user can intuitively know whether the set rinse rate is achieved through the rinse rate gear.

[0079] In another specific application of this embodiment, the washing machine displays the actual rinsing rate or the actual rinsing rate gear corresponding to the actual rinsing rate through an operation panel.

[0080] Therefore, the user can know the actual rinsing rate of the rinsing process, which is convenient for the user to use the washing device.

[0081] In a specific implementation of the present embodiment, three rinsing rate gears with increasing rinsing rates are set and are marked as Rinse 1, Rinse 2, and Rinse 3, respectively, which have successively decreasing turbidity intervals [L2, L1), [L3, L2), [L4, L3), and successively decreasing turbidity thresholds L1, L2, and L3, that is, the turbidity interval of Rinse 1 is greater than or equal to L2 and less than L1, and so on. In a specific application, the user expects to get clothes with very good rinse degree, and sets the rinse rate gear to Rinse 3. During the rinsing process, the turbidity of the washing water is detected 30 seconds before the end of the current rinse cycle, and the first turbidity is obtained. If the first turbidity is less than the turbidity threshold corresponding to Rinse 3, the rinsing process is ended after the washing tub drain operation of this rinse cycle is completed. Otherwise, the next rinse cycle is continued to run after the washing tub drain operation is performed until it is detected that the first turbidity is less than the turbidity threshold corresponding to Rinse 3 or the number of operations of the rinse cycle reaches the upper limit of the number of operations.

[0082] In this embodiment, Figure 2 As shown, during the washing process of the washing equipment, the turbidity of the washing water is continuously detected to obtain the washing turbidity; the duration for which the washing turbidity remains stable is counted; if the duration reaches the set time, the washing process is terminated, otherwise the washing process is continued.

[0083] Specifically, the washing turbidity remains stable, that is, the range of change of the washing water is within the set interval, so the duration of the washing turbidity remaining stable can reflect whether the clothes have been washed and no new stains are dropped. In a specific application of this embodiment, the set time is 2 minutes.

[0084] Furthermore, during the washing process, the running time of the washing process is counted. If the running time reaches the upper limit of the running time, the washing process is terminated and the washing tub is drained regardless of whether the duration of the washing turbidity remaining stable reaches the set time. By setting the upper limit of the running time, it is possible to avoid the situation where the washing process continues to run even if the clothes have stains that cannot be washed off. In a specific application of this embodiment, the upper limit of the running time is 30 minutes.

[0085] Therefore, by ending the washing process if the washing turbidity remains stable for a set time, the washing device automatically ends the washing process when the clothes are no longer dirty during the washing process, thereby realizing the intelligence of the washing device, further facilitating the user's use of the washing device, and saving water and electricity.

[0086] Furthermore, the washing device has a cleaning mode. In the cleaning mode, the washing device executes the above-mentioned control process, that is, detecting the turbidity of the washing water in the washing tub, and determining the corresponding turbidity threshold according to the expected rinsing rate; by comparing the turbidity and the turbidity threshold, it is determined whether to end the rinsing process.

[0087] The user can choose whether to enable the cleaning mode. If the user does not select the cleaning mode, the washing device executes the original washing program. The original washing program includes executing the washing program, rinsing program, water level, washing time and washing intensity set by the user.

[0088] In this embodiment, Figure 2 As shown, the specific process of the control method of the washing device is as follows: the user selects the washing mode through the operation panel; the user sets the washing program, rinsing program, water level, washing time, intensity and desired rinsing rate through the operation panel;

[0089] The washing device starts a washing process: during the washing process, the washing turbidity of the washing water in the washing tub is obtained, and the duration of the washing turbidity remaining stable is counted, and the running time of the washing process is counted; if the duration reaches a set time or the running time reaches an upper limit of the running time, the washing process is terminated and the washing tub is drained, otherwise the washing process is continued;

[0090] The washing device starts a cycle of a rinsing process: according to an expected rinsing rate set by a user, a corresponding turbidity threshold of washing water is determined, before the rinsing cycle runs to the washing tub being drained, a first turbidity and a second turbidity of washing water in the washing tub are obtained, and the number of operations of the rinsing cycle in this rinsing process is counted, and if the turbidity is less than the turbidity threshold, or the number of operations reaches an upper limit of the number of operations, the rinsing process is terminated after the washing tub of this rinsing cycle is drained, otherwise the next rinsing cycle is continued after the operation of draining the washing tub is performed;

[0091] It is determined whether the number of operations reaches an upper limit of the number of operations. If so, an actual rinsing rate of the corresponding rinsing process is determined according to the second turbidity, and the washing device pushes the actual rinsing rate.

[0092] In the present embodiment, the desired rinse rate set by the user is set corresponding to the turbidity threshold of the washing water during the rinsing process, and the turbidity is compared with the turbidity threshold to determine whether to terminate the rinsing process, so that the different needs of the user for the rinsing rate can be realized in the rinsing process of the washing device, and the user's demand for the rinsing rate is met while avoiding the user manually setting an excessively long rinsing process to achieve a high rinse rate, thereby achieving water and electricity saving; by terminating the washing process if the washing turbidity remains stable for a set time, the washing device automatically terminates the washing process when the clothes are no longer dirty during the washing process, thereby achieving intelligence of the washing device, further facilitating the user's use of the washing device, and saving water and electricity; by determining whether to terminate the barrel self-cleaning rinsing stage according to the rinse turbidity, the barrel self-cleaning rinsing stage is automatically and accurately terminated, thereby achieving intelligence of the washing device, further facilitating the user's use of the washing device, and saving water and electricity.

[0093] Embodiment 2

[0094] like Figures 1 to 3 As shown, this embodiment provides a control method for a washing device. Based on the first embodiment, this embodiment provides a control method for a washing tub self-cleaning program, and the control method includes: the washing device has a washing tub self-cleaning program; during the operation of the washing tub self-cleaning program, the washing device detects the turbidity of the washing water to obtain the rinse turbidity, and determines whether to end the washing tub self-cleaning program according to the rinse turbidity.

[0095] Therefore, by judging whether to end the barrel self-cleaning program according to the rinse turbidity, the barrel self-cleaning program can be automatically and accurately ended, the intelligent washing equipment is realized, the user's use of the washing equipment is further facilitated, and water and electricity are saved.

[0096] In this embodiment, Figure 3 As shown, the specific process of the control method of the washing tub self-cleaning program of the washing equipment is as follows:

[0097] Start the washing tub self-cleaning program;

[0098] Starting the tub self-cleaning washing soaking stage: During the washing soaking stage, the turbidity of the washing water is detected to obtain the soaking turbidity, and the corresponding degree of dirtiness of the washing tub is determined according to the soaking turbidity, and the degree of dirtiness of the washing tub is notified to the user;

[0099] Starting the barrel self-cleaning and rinsing stage: During the barrel self-cleaning and rinsing stage, the turbidity of the washing water is detected to obtain the rinsing turbidity, and whether to end the barrel self-cleaning and rinsing stage is determined according to the rinsing turbidity.

[0100] Specifically, the washing water in the washing tub is detected by the turbidity detection device 3 to obtain the soaking turbidity and the rinsing turbidity. The turbidity detection device 3 communicates with the control system of the washing equipment, and the control system stores and calculates and analyzes the soaking turbidity and the rinsing turbidity.

[0101] Specifically, the barrel self-cleaning and rinsing stage is a cyclic operation of several rinsing programs. The actual number of operations of the barrel self-cleaning and rinsing stage is counted, and a maximum number of rinses is set. If the actual number of operations of the barrel self-cleaning and rinsing stage reaches the maximum number of rinses, the barrel self-cleaning and rinsing stage is ended after the current rinsing program is ended, and a prompt message "There is still dirt that has not been cleaned in the washing barrel, and deep cleaning is recommended" is issued to notify the user.

[0102] In a specific application of this embodiment, the washing device is an IoT-type washing device. By communicating with a mobile device, the dirtiness of the washing tub and / or a prompt message of "there is still uncleaned dirt in the washing tub, deep cleaning is recommended" can be sent to the user in the application and / or display page, thereby facilitating the user's use of the washing device.

[0103] Therefore, in this embodiment, the user can conveniently and accurately know the running status of the washing tub self-cleaning program, and make the washing tub self-cleaning program more water-saving and electricity-saving.

[0104] Embodiment 3

[0105] like Figures 1 to 5 As shown, this embodiment provides a washing device, and the washing device of this embodiment is used to execute the control method of the washing device described in Example 1 and Example 2, and the washing device includes: a turbidity detection device 3, used to detect the turbidity of washing water in the washing tub; an operation panel, used to obtain the expected rinsing rate set by the user; a control system, used to determine the corresponding turbidity threshold value according to the expected rinsing rate, and judge whether to end the rinsing process by comparing the turbidity and the turbidity threshold value.

[0106] The turbidity detection device 3 and the control system ensure accurate detection and acquisition of the turbidity of the washing water, and the operation panel facilitates the user to set the desired rinsing rate.

[0107] Specifically, Figure 4 As shown, the turbidity detection device 3 is internally provided with an infrared pair tube for directly irradiating the washing water in the washing tub, and the light intensity of the infrared light generated by the infrared pair tube passing through the washing water is detected by the receiving end of the infrared pair tube, and a corresponding current is generated according to the light intensity, and a corresponding electrical signal is generated according to the current, so that the turbidity of the washing water, that is, the light transmittance of the washing water, can be accurately detected by the turbidity detection device 3.

[0108] In a specific application of this embodiment, Figure 4 As shown, the infrared pair tube is IR958 and PT958 packaged, and the turbidity detection device 3 is arranged on the side wall or bottom wall of the inner drum 1 of the washing equipment, and part of it passes through the side wall or bottom wall of the inner drum 1 and is located between the inner drum 1 and the outer drum 2.

[0109] In a specific application of this embodiment, Figure 5 As shown, the operation panel is provided with a washing mode option, a power on / off option, a start / pause option, a water level setting option, a washing and rinsing program option, a washing process option, a washing intensity option, a rinsing rate gear, a clothing type option, a child lock indicator light and a power-on indicator light in sequence, and a two-digit digital tube is provided so that the rinsing rate can be set to a precise value through the digital tube, or a rinsing rate gear can be selected.

[0110] Specifically, the control system includes a computer control board, which is connected to the turbidity detection device 3 and the operation panel through its I / O interface to achieve communication with the turbidity detection device 3 and the operation panel, and analyze the received data.

[0111] Therefore, the turbidity detection device 3 and the control system ensure accurate detection and acquisition of the turbidity of the washing water, and the operation panel facilitates the user to set the desired rinsing rate.
