Description

Technical Field

[0001] The present invention relates to a tableware condition judgment method, and also relates to a tableware cleaning method using the tableware condition judgment method. Furthermore, it also relates to a cleaning machine using the tableware condition judgment method and / or the tableware cleaning method. Background Art

[0002] As people's living standards continue to improve, washing machines for washing dishes are more widely used. The number of dishes is an important parameter for determining the cleaning parameters in the washing machine. In the prior art, some detection devices are used to detect the number of dishes in the washing machine, and then the corresponding cleaning parameters are matched according to the detection results, so as to achieve a balanced match between energy saving and cleaning effect.

[0003] There are several methods for detecting the number of tableware currently used in washing machines.

[0004] 1. Use a weight sensor to obtain the weight of the dishes and then determine the approximate number of dishes. This method cannot accurately identify the specific size of the dishes, and the error in estimating the number of dishes is large. Assuming that the weight of 5 small bowls is the same as that of 1 large bowl, the number of dishes estimated by weighing is quite different from the actual number of dishes, and cannot match the actual cleaning parameters, which will lead to poor cleaning results or excessive consumption of energy such as water and electricity.

[0005] 2. Use image recognition technology to identify the number of tableware in the trough and the condition of the tableware, such as the Chinese invention patent application "Control method, device, dishwasher and processor for dishwasher" with publication number CN112869679A (application number 202110328020.1), in which the method disclosed uses an image acquisition device to obtain the condition of the tableware in the washing machine, and the process of placing the tableware is dynamically photographed. This technology requires the setting of corresponding image acquisition equipment, and the requirements for data processing chips are also high, which greatly increases the equipment cost and is relatively complex to implement. In addition, the recognition rate is affected by factors such as the clarity of the camera and whether the placement action blocks the tableware, and the recognition error rate is high. Summary of the invention

[0006] The first technical problem to be solved by the present invention is to provide a tableware condition determination method for the above-mentioned prior art, which can determine the tableware condition according to the expansion and contraction amount of the tableware rack, and thus more accurately understand the placement condition of the tableware rack.

[0007] The second technical problem to be solved by the present invention is to provide a tableware cleaning method that can more accurately determine cleaning parameters according to the tableware conditions in view of the above-mentioned prior art.

[0008] The third technical problem to be solved by the present invention is to provide a cleaning machine that applies the above-mentioned tableware condition judgment method and / or tableware cleaning method in view of the above-mentioned prior art.

[0009] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a tableware condition judgment method, characterized in that: a tableware rack that can be telescopic left and right and front and back is adopted;

[0010] After the tableware is placed on the tableware rack in the original state; the tableware rack is controlled to shrink and move in the left-right direction, and the first shrinking distance L1 of the tableware rack in the left-right direction is calculated; the tableware rack is controlled to shrink and move in the front-back direction, and the second shrinking distance L2 of the tableware rack in the front-back direction is calculated;

[0011] The tableware condition is determined based on the change in the first contraction distance L1 relative to the lateral width Lc of the tableware rack in the original state along the left-right direction, and the change in the second contraction distance L2 relative to the longitudinal width Lw of the tableware rack in the original state along the front-back direction.

[0012] Preferably, the tableware condition parameter A reflecting the tableware condition is calculated and obtained as A=(Lc-L1)*(Lw-L2) / Lc*Lw.

[0013] Preferably, the first motor group is used to drive the cutlery rack to move in a contraction direction along the left-right direction, and the second motor group is used to drive the cutlery rack to move in a contraction direction along the front-back direction;

[0014] When the cutlery rack is driven to retract and move in the left-right direction, the working current of the first motor group is obtained in real time, and when the working current of the first motor group suddenly changes, it is determined that the cutlery rack is retracted to the right-left direction;

[0015] When the cutlery rack is driven to retract and move along the front-to-back direction, the working current of the second motor group is obtained in real time. When the working current of the second motor group suddenly changes, it is determined that the cutlery rack has been retracted into place along the front-to-back direction.

[0016] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: a tableware cleaning method, characterized in that: the tableware cleaning parameters are determined according to the tableware condition parameter A by applying the tableware condition judgment method as mentioned above.

[0017] Preferably, at least two continuous tableware condition parameter ranges are preset, and different cleaning parameters are set corresponding to each tableware condition parameter range.

[0018] In order to fully clean the tableware, after determining the tableware cleaning parameters, the cleaning work is carried out according to the tableware cleaning parameters. At the same time, during the cleaning process, the tableware rack is controlled to alternately stretch and contract the tableware rack along the left and right directions, and stretch and contract the tableware rack along the front and back directions.

[0019] Preferably, after the tableware is washed, the tableware rack is controlled to be driven to return to its original state.

[0020] Preferably, the tableware washing parameters include water volume, water temperature, washing time, and drying time at the end of washing.

[0021] The technical solution adopted by the present invention to solve the third technical problem is: a washing machine, comprising a box body, and a tableware rack detachably arranged in the box body, characterized in that: the tableware condition judgment method as described above is applied; and / or the tableware washing method as described above is applied;

[0022] The cutlery rack is a frame that can be extended left and right and front and back. The box body is provided with a first driving mechanism for driving the cutlery rack to extend left and right and a second driving mechanism for driving the cutlery rack to extend front and back. The first driving mechanism and the second driving mechanism are both connected to the cutlery rack.

[0023] The structure is simple. The cutlery rack includes a base frame and a plurality of support rods. The base frame includes a plurality of first rods extending in parallel along the left-right direction and a plurality of second rods extending in parallel along the front-back direction. The first rods and the second rods are cross-connected, and both the first rods and the second rods are retractable rods. The support rods are vertically connected to the intersection nodes of the first rods and the second rods based on a partitioned arrangement.

[0024] Preferably, the first driving mechanism comprises at least one first motor group, and the second driving mechanism comprises at least one second motor group;

[0025] The first motor group and the second motor group both include a motor, a screw connected to the motor driving end and located below the base frame, and a connecting piece threadedly sleeved on the screw; a buckle that can be connected to the connecting piece is provided on the base frame.

[0026] In order to facilitate the placement of the cutlery rack in the box, a magnet is provided in each buckle, and a reed switch is provided on the side wall of the box corresponding to each buckle.

[0027] In order to effectively ensure that the cutlery rack is placed in the box in the initial state and improve the accuracy of the calculation of the cutlery condition parameter A, the placement of the cutlery rack in the box is judged based on the reed switch signal;

[0028] When the cleaning machine is in the door-opening state, the signals of each reed switch are detected and obtained;

[0029] When all the reed switch signals are high level signals, it is determined that the cutlery rack is placed in the box and is in the original state;

[0030] When the signals of all reed switches are low level signals, it is determined that no cutlery rack is placed in the box;

[0031] When the signals of some reed switches are at a high level and the signals of other reed switches are at a low level, the motor at the position corresponding to the reed switch with a low control signal drives the cutlery rack to expand in the corresponding direction until the motor is blocked, so that the corresponding buckle is close to the reed switch with a low control signal; then the reed switch signals are re-detected to determine whether the signals of all reed switches are high level signals. If so, it is determined that the cutlery rack is placed in the box and is in its original state; if not, it is determined that the cutlery rack is faulty.

[0032] Preferably, the first driving mechanism comprises two groups of first motor groups, and the two groups of first motor groups are respectively arranged on the left and right side walls of the box;

[0033] The second driving mechanism comprises two groups of second motor groups, and the two groups of second motor groups are respectively arranged on the front and rear side walls of the box body.

The data acquisition process of this method is simpler and the amount of calculation is also small. The tableware cleaning method using the tableware condition judgment method can match more accurate cleaning parameters based on accurate tableware condition parameters, and the cleaning effect is better.

[0035] A cleaning machine that applies a tableware condition judgment method and / or a tableware cleaning method can automatically and accurately obtain the placement condition of the tableware in the cleaning machine, which is conducive to matching cleaning parameters that match the tableware condition, thereby achieving better cleaning effects.

[0042] The present invention is further described in detail below with reference to the accompanying drawings.

[0043] like Figures 1 to 5 As shown, the cleaning machine in this embodiment includes a box body 1, a cutlery rack 2 detachably arranged in the box body 1, a first driving mechanism for driving the cutlery rack 2 to extend and retract left and right, and a second driving mechanism for driving the cutlery rack 2 to extend and retract front and back.

[0044] The cutlery rack 2 is a frame that can be telescopic left and right and telescopic front and back. Specifically, the cutlery rack 2 includes a base frame 21 and a plurality of struts 22. The base frame 21 is a mesh plane structure that crosses vertically and horizontally. Specifically, the base frame 21 includes a plurality of first rods 211 extending in parallel along the left and right directions and a plurality of second rods 212 extending in parallel along the front and back directions. The first rod 211 and the second rod 212 are cross-connected. The first rod 211 and the second rod 212 are both telescopic rods. The first rod 211 and the second rod 212 can be telescopic at other positions except the cross-connection point. As needed, the first rod 211 and the second rod 212 can choose to adopt any folding or pull-out telescopic structure in the prior art. The struts 22 are vertically connected to the intersection nodes of the first rod 211 and the second rod 212 based on the partition arrangement. That is, the struts 22 are used to enclose areas for placing tableware such as rice bowls, soup bowls, and plates, and to form grids in each area for placing tableware. In order to ensure the stability of the support rods 22, retractable support rods 22 may be connected between the middle sections of adjacent support rods 22 to ensure the stability of the connection between the support rods 22 and improve the support capacity for placing tableware.

[0045] The first driving mechanism and the second driving mechanism are both arranged on the box body 1. The first driving mechanism and the second driving mechanism are both connected to the cutlery rack 2 to realize the telescopic driving of the cutlery rack 2 in the left-right direction and the front-back direction.

[0046] The first driving mechanism includes at least one first motor group 3, and the second driving mechanism includes at least one second motor group 4. The number of the first motor group 3 and the second motor group 4 is determined according to the driving distance thereof and the size of the dish rack 2. In this embodiment, the first driving mechanism includes two first motor groups 3, and the two first motor groups 3 are respectively arranged on the left and right side walls of the box body 1. The second driving mechanism includes two second motor groups 4, and the two second motor groups 4 are respectively arranged on the front and rear side walls of the box body 1.

[0047] The first motor group 3 and the second motor group 4 both include a motor 5, a screw rod 6 connected to the driving end of the motor 5 and located below the base frame 21, and a connector 7 threadedly sleeved on the screw rod 6. The screw rod 6 extends to the inside of the box body 1 to the bottom of the base frame 21 along the driving direction of the corresponding motor group 5, so as not to affect the placement of tableware in the cutlery rack 2. A buckle 8 that can be connected to the connector 7 is provided on the base frame 21. The buckle 8 can be connected to the connector 7 by a snap-on method, and a magnet can also be provided inside the buckle 8 to be attracted to the connector 7. When the motor 5 is working, the screw rod 6 is driven to rotate, thereby driving the connector 7 to move along the extension direction of the screw rod 6. The buckle 8 and the connector 7 move, thereby driving the cutlery rack 2 to perform telescopic movements in the left and right directions and the front and back directions. In order to ensure that the telescopic range of the cutlery rack 2 can reach the maximum, the position corresponding to the connector 7 is set at the edge of the base frame 21 in the cutlery rack 2.

[0048] In order to effectively determine whether the cutlery rack 2 is placed in the box body 1 in its original state, thereby improving the intelligence of the self-cleaning operation of the cleaning machine, in this embodiment, a magnet is arranged in each buckle 8, and a reed switch 9 is respectively arranged on the side wall of the box body 1 corresponding to each buckle 8. The reed switch 9 is inductively sensed to the magnet to determine whether the cutlery rack 2 is placed in the box body 1, and the posture of the cutlery rack 2 in the box body 1 can also be determined.

[0049] Specifically, the placement of the cutlery rack 2 in the box 1 is determined based on the signal of the reed switch 9, and the method includes the following steps. When the cleaning machine is in an open state, the signal of each reed switch 9 is detected. When the signals of each reed switch 9 are all high-level signals, it means that each buckle 8 has been close to the side wall of the box 1, and then the reed switch 9 is triggered by the magnet in the buckle 8. In this way, it can be determined that the cutlery rack 2 is placed in the box 1 and the cutlery rack 2 is in the original state. The original state is the state where the cutlery rack 2 just matches the inner wall of the box 1. When the signals of each reed switch 9 are all low-level signals, it is determined that the cutlery rack 2 is not placed in the box 1. When the signals of some reed switches 9 are high and the signals of other reed switches 9 are low, it means that the cutlery rack 2 may be retracted when placed. At this time, the motor 5 at the position corresponding to the reed switch 9 with a low signal can be controlled to drive the cutlery rack 2 to expand in the corresponding direction until the motor 5 is blocked. At this time, it means that the cutlery rack 2 has been driven to expand to the maximum extension position, so that the corresponding buckle 8 is close to the reed switch 9 with a low control signal; then re-detect the reed switch 9 signal to determine whether the signals of each reed switch 9 are high-level signals. If so, it is determined that the cutlery rack 2 is placed in the box 1 and the cutlery rack 2 is in its original state; if not, it is determined that the cutlery rack 2 is faulty.

[0050] The aforementioned washing machine uses the following tableware condition determination method to determine the quantity of tableware placed in the washing machine. The washing machine can also use the following tableware cleaning method to clean the tableware, thereby achieving a good cleaning effect.

[0051] The tableware condition judging method of the present invention requires a tableware rack 2 that can be telescoped left and right and front and back. The tableware rack 2 can adopt various existing telescopic structures that can perform telescopic actions, such as the aforementioned tableware rack 2.

[0052] like Figure 6 As shown, the tableware condition judgment method is specifically as follows: after the tableware is placed on the tableware rack 2 in the original state; the tableware rack 2 is controlled to shrink and move in the left-right direction, and a first shrinking distance L1 of the tableware rack 2 in the left-right direction is calculated. The tableware rack 2 is controlled to shrink and move in the front-back direction, and a second shrinking distance L2 of the tableware rack 2 in the front-back direction is calculated.

[0053] Specifically, the first motor group 3 is used to drive the cutlery rack 2 to shrink and move along the left-right direction, and the second motor group 4 is used to drive the cutlery rack 2 to shrink and move along the front-back direction. When the cutlery rack 2 is driven to shrink and move along the left-right direction, the working current of the first motor group 3 is obtained in real time. When the working current of the first motor group 3 suddenly changes, it is determined that the cutlery rack 2 is shrinking in place along the left-right direction. At this time, the first shrinkage distance L1 can be calculated based on the working data of the first motor group 3. When the cutlery rack 2 is driven to shrink and move along the front-back direction, the working current of the second motor group 4 is obtained in real time. When the working current of the second motor group 4 suddenly changes, it is determined that the cutlery rack 2 is shrinking in place along the front-back direction. At this time, the second shrinkage distance L2 can be calculated based on the working data of the second motor group 4.

[0054] For the structure of the first motor group 3 and the second motor group 4 in the aforementioned cleaning machine, the drive of the cutlery rack 2 is achieved based on the structure of the screw 6. The driving distance in one direction of the cutlery rack 2 can be calculated by the number of revolutions of the motor 5 and the pitch of the screw 6.

[0055] The tableware condition is determined based on the change of the first contraction distance L1 relative to the horizontal width Lc of the tableware rack in the original state along the left-right direction, and the change of the second contraction distance L2 relative to the longitudinal width Lw of the tableware rack in the original state along the front-back direction. For example, the parameter characterizing the tableware condition can be determined based on the sum of the distance difference between L1 and Lc and the distance difference between L2 and Lw.

[0056] In this embodiment, the tableware condition parameter A=(Lc-L1)*(Lw-L2) / Lc*Lw that reflects the tableware condition is calculated. The larger the A is, the more tableware is placed in the tableware rack 2 or the larger the volume is. The smaller the A is, the fewer tableware is placed in the tableware rack 2 or the smaller the volume is. In this way, the characterization data characterizing the quantity and volume of tableware can be accurately obtained based on the tableware condition parameter A. Based on the tableware condition parameter A on the tableware rack 2, any control action related to the tableware condition data in the washing machine can be realized.

[0057] like Figure 6 As shown, the tableware cleaning method of the present invention applies the tableware condition judgment method as described above, and then determines the tableware cleaning parameters according to the tableware condition parameter A. The tableware cleaning parameters include water volume, water temperature, cleaning time, and drying time at the end of cleaning. Of course, depending on the specific cleaning machine, cleaning parameters that match the cleaning machine can also be set, such as the number of cleaning paths, cleaning speed, and other cleaning parameters.

[0058] Usually, at least two continuous tableware condition parameter ranges are preset, and different cleaning parameters are set for each tableware condition parameter range. Based on the test in product development, six tableware condition parameter ranges are set in this embodiment, and then based on these six tableware condition parameter ranges, six corresponding cleaning levels are determined, and the cleaning parameters corresponding to each cleaning level are also different. The details are shown in the following table.

[0059]

[0060] After determining the tableware cleaning parameters according to the calculated tableware condition parameters A, the cleaning work is performed according to the tableware cleaning parameters. At the same time, during the cleaning process, the tableware rack 2 is controlled to alternately stretch and contract the tableware rack 2 along the left and right directions, and along the front and back directions. This ensures that the water flow in the box 1 fully rinses the tableware on the tableware rack 2, thereby improving the cleanliness of the tableware.

[0061] After the tableware is washed, the first motor group 3 and the second motor group 4 are controlled to drive the tableware rack 2 to reset to the original state. During the reset process, the stall current of the first motor group 3 and the second motor group 4 is used as a signal to judge whether the reset is in place. Then the tableware is dried. In this embodiment, the drying time for the tableware is T = A*T0, where T0 is the preset maximum drying time.

[0062] The tableware condition judgment method of the present invention can accurately obtain the tableware placement condition on the tableware rack 2 based on the shrinkage distance data of the tableware rack 2 after the tableware is placed, and is not easily affected by other factors and has a large error in the tableware condition result. The data acquisition process of this method is simpler and the amount of calculation is small. The tableware cleaning method using the tableware condition judgment method can match more accurate cleaning parameters based on accurate tableware condition parameters, and the cleaning effect is better.

[0063] A cleaning machine that applies a tableware condition judgment method and / or a tableware cleaning method can automatically and accurately obtain the placement condition of the tableware in the cleaning machine, which is conducive to matching cleaning parameters that match the tableware condition, thereby achieving better cleaning effects.

Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
