Description

Technical Field

[0001] The present invention relates to the technical field of dishwashers, and in particular to a dishwasher with a residue crushing function and a control method thereof. Background Art

[0002] In the existing dishwashers with a debris crushing function, during the process of crushing food residues, the controller usually adopts a food residue crushing program with a predetermined motor speed and a predetermined running time. Since the mixture of food residues crushed each time is different, if the motor speed is set too high, lighter food residues may splash, causing secondary contamination of tableware.

[0003] In addition, if users fail to promptly discover that tableware has been contaminated by splashed food residues, tableware left in the dishwasher for a long time will breed bacteria and produce odors. When users use the cleaned tableware and find that there are residues on the tableware, they need to put it back into the dishwasher and manually reset the cleaning program, which is troublesome and causes energy loss, seriously affecting the user experience.

[0052] The following examples illustrate the present invention, but the present invention is not limited to these examples. Modifications to the specific embodiments of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed by the present invention.

[0053] Example 1

[0054] like Figure 1-3As shown, this embodiment provides a dishwasher with a debris crushing function, including a washing chamber 1, a debris crushing module (not shown in the figure), an identification module 3, a control module 4 and a spray module 6, wherein an opening for water flow and / or food residues to pass through is provided at the bottom of the washing chamber 1. The debris crushing module includes an outer cover 21, a debris crushing assembly 22 and a driving assembly 23, wherein the outer cover 21 is arranged at the bottom of the washing chamber 1 and is connected to the opening, so that the water and / or food residues in the washing chamber 1 can enter the outer cover 21; the debris crushing assembly 22 is rotatably arranged in the outer cover 21, and is used to crush the food residues; the output end of the driving assembly 23 is connected to the debris crushing assembly 22, and is used to drive the debris crushing assembly 22 to work, so as to control the start and stop of the food residue crushing work. The identification module 3 is arranged at the opening or the position of the outer cover 21 close to the opening, and is used to identify whether there is food residue splashing from the outer cover 21 toward the washing chamber 1 (hereinafter referred to as food splashing). Therefore, according to the recognition result of the identification module 3, it can be identified whether there is food residue splashing during the debris crushing process to cause secondary contamination of the tableware. The spray module 6 is rotatably disposed in the washing chamber 1, and the spray module 6 is connected to the washing water source through the water inlet assembly. The control module 4 is electrically connected to the drive assembly 23, the identification module 3 and the water inlet assembly, respectively, and is used to determine whether to adjust the working parameters of the drive assembly 23 and whether to control the water inlet assembly to supply water to the spray module 6 according to the identification result of the identification module 3 during the slag crushing process, wherein the working parameter is the current or the rotation speed.

[0055] When the dishwasher starts the food residue crushing program, the control module 4 controls the drive component 23 to start, and the output end of the drive component 23 drives the crushing component 22 to work and crush the food residue. At the same time or later, the recognition module 3 is controlled to start. If the recognition module 3 recognizes that there is food splashing, it is necessary to lower the working parameters of the drive component 23 until no food splashes out of the outer cover 1 during the crushing process; if the recognition module 3 does not recognize that there is food splashing, the drive component 23 is controlled to operate according to the original preset working parameters Z until the food residue crushing program ends.

[0056] When food splashing is identified, the working parameters of the drive component 23 can be lowered first until no food splashes out of the outer cover 21, and then the tableware spray cleaning program is started, and the food residue crushing program is restarted after the tableware spray cleaning program; or, when food splashing is identified, the tableware spray cleaning program is started first, and after the tableware spray cleaning program, the working parameters of the drive component 23 are lowered first, and then the food residue crushing program is restarted.

[0057] It can be seen that the dishwasher of this embodiment can identify whether there is food residue splashing and causing secondary contamination of tableware during the debris crushing process by adding an identification module 3 at the opening at the bottom of the washing chamber 1 or at a position close to the opening of the outer cover 21. In addition, by controlling the drive component 23 to operate according to the original set working parameter Z when no food splashing is identified, or lowering the working parameters of the drive component 23 when food splashing is identified, until no food splashes out of the outer cover 1 during the debris crushing process, it is possible to reduce the probability of secondary contamination of tableware caused by food splashing during the debris crushing process. When food splashing is identified, by starting the tableware spray cleaning program before or after lowering the working parameters of the drive component 23, an automatic spray cleaning operation after secondary contamination of the tableware can be achieved, effectively ensuring the cleaning effect of the tableware.

[0058] like Figure 3 As shown, further, a constriction portion 211 and a mounting opening 212 are provided at one end of the outer cover 21 near the opening, the diameter of the constriction portion 211 gradually decreases from bottom to top, the mounting opening 212 is located between the constriction portion 211 and the opening, and the mounting opening 212 is connected to the opening. Therefore, by adding a constriction portion 211 that shrinks from bottom to top below the mounting opening 212, the constriction portion 211 can prevent food from splashing toward the mounting opening 211 to a certain extent, thereby reducing food splashing during the crushing process. In addition, since the constriction portion 211 is formed as an integral part of the upper end of the side wall of the outer cover 21, which is tilted inward and upward, it is convenient to quickly process the constriction portion 211, improve processing efficiency, and reduce manufacturing costs.

[0059] In this embodiment, the installation opening 212 is a columnar shape with an invariable diameter from bottom to top. In other embodiments, in order to better guide water flow and food residues into the interior of the outer cover 21, the installation opening 212 can be designed as an expansion structure with a diameter gradually increasing from bottom to top.

[0060] Preferably, the outer cover 21 is provided with at least one slag discharge port (not shown in the figure), which is connected to the sewer through the slag discharge pipe 5. In this way, the crushed residue in the outer cover 21 can be discharged in time through the connected slag discharge port and the slag discharge pipe 5. In addition, a water outlet valve (not shown in the figure) electrically connected to the control module 4 can be added to the slag discharge pipe 5. In this way, by controlling the switch of the water outlet valve, it can be realized whether the outer cover 21 drains water or discharges slag to the sewer. In addition, an anti-backflow structure or an anti-odor structure for odor reversal can also be set on the slag discharge pipe 5.

[0061] like Figure 3As shown, preferably, the driving component 23 includes a driver 231 and a linkage shaft 232 electrically connected to the control module 4. A mounting hole (not shown in the figure) is provided at the bottom of the outer cover 21. The driver 231 is a driving motor, which is arranged below the bottom of the outer cover 21 and its output end faces the mounting hole. The upper end of the linkage shaft 232 is connected to the slag crushing component 22, and the lower end passes through the mounting hole and is connected to the output end of the driver 231. In this way, by placing the driver 231 below the bottom of the outer cover 21, the driver 231 can be prevented from being disturbed by water flow and food residues, thereby improving the safety of the driver 231.

[0062] like Figure 3 As shown, preferably, the slag crushing module also includes a paddle 24, which is rotatably arranged in the outer cover 21 and located above the slag crushing assembly 22, and the paddle 24 is connected to the linkage shaft 232 of the driving assembly 23, and is used to push the crushed residue out of the slag discharge port. Therefore, by adding the paddle 24 connected to the driving shaft 232, when the driving assembly 23 is started, the slag crushing assembly 22 and the paddle 24 can be synchronously driven to rotate coaxially, so that the food residue is crushed while the crushed residue is discharged from the outer cover 21, achieving the effect of synchronous linkage crushing and slag discharge, avoiding the crushed residue from being easily lifted up by the slag crushing assembly 22 due to its light weight and causing splashing, which is conducive to further reducing the probability of secondary contamination of tableware caused by food splashing during the crushing process.

[0063] In this embodiment, the paddle 24 includes at least one blade, each blade includes a connecting section 241 and two slag pushing sections 242, wherein the connecting section 241 is arranged horizontally and sleeved on the linkage shaft 232, and the connecting section 241 is tightly connected to the linkage shaft 232 to ensure that the driving assembly 23 can reliably drive the blade to rotate. The two slag pushing sections 242 are arranged below the connecting section 241, and the two slag pushing sections 242 are respectively connected to the opposite ends of the connecting section 241, so that the blade is in a "concave" shape with an opening facing downward, and the slag crushing assembly 22 is surrounded between the two slag pushing sections 242, and the slag pushing sections 242 are used to push the crushed food residues to the outside of the slag discharge port.

[0064] Preferably, each slag pushing section 242 is fitted with a clearance inside the side wall of the outer cover 21, so that, on the one hand, the rotation of the slag pushing section 242 is not hindered by the side wall of the outer cover 21, and on the other hand, it is convenient to squeeze the crushed residue between the slag pushing section 242 and the side wall of the outer cover 21 out of the slag crushing port.

[0065] like Figure 3 As shown, further, the recognition module 3 is an infrared sensor or an image detection unit. In this embodiment, the recognition module 3 is an infrared sensor as an example. In this embodiment, the installation of the recognition module 3 can be any of the following installation methods:

[0066] In the first installation mode, the washing chamber 1 is provided with a mounting portion (not shown in the figure) at the opening, and the infrared sensor is arranged on the mounting portion;

[0067] In the second installation mode, the infrared sensor is installed on the side wall of the installation opening 212, and the probe part of the infrared sensor is located inside the installation opening 212, so as to identify whether there is food splashing in the installation opening 212 during the slag crushing process.

[0068] like Figure 1 As shown in Figure 2, it further includes a spray module 6 and a water inlet assembly (not shown in the figure), and the spray module 6 is rotatably arranged in the washing chamber 1, and is used to wash the dishes in the washing chamber 1. The water inlet end of the water inlet assembly is connected to the washing water source, and the water outlet end is connected to the water inlet of the spray module 6. In this way, the spray module 6 is connected to the washing water source through the water inlet assembly, which can avoid recycling the water in the outer cover 21, thereby ensuring that the spray washing water is clean and not contaminated by food residues, which is conducive to improving the tableware cleaning effect.

[0069] Preferably, the spray module 6 may only include a top spray arm 61, see Figure 1 Of course, the spray module 6 can also be designed to include at least a top spray arm 61 and a bottom spray arm 62, see Figure 2 Thus, when washing dishes by spraying, the cleaning effect and cleaning efficiency can be significantly improved by synchronously starting the top spray arm 61 and the lower spray arm 62.

[0070] Preferably, the water inlet assembly includes a water inlet pipeline 71, a water inlet valve 72 and a booster pump 73. The water inlet end of the water inlet pipeline 71 is connected to the cleaning water source, and the water outlet end is connected to the water inlet of the spray module 6. The water inlet valve 72 and the booster pump 73 are respectively arranged on the water inlet pipeline 71, and the control module 4 is electrically connected to the water inlet valve 72 and the booster pump 73 respectively.

[0071] Example 2

[0072] like Figure 4 As shown, the difference between this embodiment and embodiment 1 is that a blocking portion 213 is provided in the outer cover 21 and is located between the identification module 3 and the slag assembly 22. The blocking portion 213 has a free end and a connecting end that are relatively arranged, wherein the connecting end is connected to the upper end of the inner wall of the outer cover 21, and the free end is arranged inwardly and tilted downward, and the free end of the blocking portion 213 is higher than the paddle 24 to avoid affecting the slag pushing work of the paddle 24 due to the setting of the blocking portion 213. Since the blocking portion 213 is arranged to be tilted downward, on the one hand, food residues and water flow can be guided to the bottom of the blocking portion 213, and on the other hand, the residues can be prevented from splashing upward to the installation port 212, thereby significantly reducing the probability of the identification module 3 recognizing that there is food splashing.

[0073] Preferably, the blocking portion 213 is arranged at the necked portion 211, and the connecting end of the blocking portion 213 is fixedly arranged at the upper end of the side wall of the necked portion 211 close to the mounting opening 212, so that the side wall of the necked portion 211 and the blocking portion 213 are together enclosed to form an inverted "V"-shaped blocking layer, and the flying residues in the outer cover 21 are blocked by the blocking layer, thereby preventing food from splashing out of the outer cover 21, further improving the blocking effect of food splashing.

[0074] In this embodiment, the blocking portion 213 may be an annular baffle. Of course, it may also be designed as baffles alternately arranged in the vertical direction and the circumferential direction. Other parts are the same as those in the first embodiment.

[0075] It can be seen that this embodiment can further enhance the blocking effect of food splashing by adding a blocking portion 213 in the outer cover 21, reduce the probability of secondary contamination of tableware caused by food splashing during the crushing process, and while preventing food from splashing out of the outer cover 21, the rotation speed of the paddle 24 and the crushing assembly 22 can be increased to a certain extent, so as to further improve the efficiency of the synchronous linkage crushing and slag discharge.

[0076] Example 3

[0077] like Figure 5 As shown, the difference between this embodiment and the second embodiment is that the shape of the outer cover 21 is different. The outer cover 21 of this embodiment has no constricted portion 211, and the diameter of the installation opening of the outer cover 21 is increased to make the inlet area of ​​the outer cover 21 larger, making it easier for water and food residues to enter the outer cover 21. The connection end of the blocking portion 213 is fixedly arranged at the upper end of the inner side wall of the outer cover 21 and close to the installation opening, and the free end is arranged inwardly and tilted downward, and the other parts are the same as those of the first embodiment.

[0078] It can be seen that by omitting the constricted portion 211 on the outer cover 21 and adding a blocking portion 213 close to the installation opening at the upper end of the inner wall of the outer cover 21, the blocking portion 213 can prevent food from splashing toward the installation opening, thereby reducing the probability of food splashing during the crushing process.

[0079] Example 4

[0080] like Figure 6 As shown, this embodiment provides a control method for a dishwasher, which applies the control method for a dishwasher as described in Embodiment 1, 2 or 3, and the control method comprises the following steps:

[0081] S1, start the food residue crushing program;

[0082] Specifically, after the dishwasher completes tableware cleaning and exits the tableware cleaning mode, the food residue crushing program of the dishwasher is started again. In this way, in the tableware cleaning mode, the rotational resistance of the residue crushing component 22 will increase due to excessive water in the outer cover 21. By starting the food residue crushing program of the dishwasher after the dishwasher completes tableware cleaning and exits the tableware cleaning mode, it is possible to effectively avoid the impact of the water in the outer cover 21 on the crushing efficiency of the residue crushing component 22.

[0083] S2, start the driving component 23 to make the slag crushing component 22 rotate to crush the food residues, and start the identification module 3 at the same time or with a delay;

[0084] S3, determining whether food residues are splashed from the outer cover 21 toward the washing chamber 1, if yes, proceeding to step S51, if no, proceeding to step S4;

[0085] S4, controlling the driving component 23 to operate according to the originally set working parameter Z until the food residue crushing program is finished;

[0086] S51, turning off the drive assembly 23 and the identification module 3, and starting the tableware spray cleaning program;

[0087] S61, after the tableware spray cleaning program is completed, restart the food residue crushing program;

[0088] S71, start the driving component 23 and lower the working parameters of the driving component 23, and start the identification module 3 at the same time or with a delay;

[0089] S81, determining whether food residues are splashed from the outer cover 21 toward the washing chamber 1, if yes, proceeding to step S51, if no, proceeding to step S4.

[0090] It can be seen that the control method of this embodiment determines whether there is food residue splashing from the outer cover 21 toward the washing chamber 1 during the debris crushing process, and controls the driving component 23 to operate according to the original set working parameter Z when no food splashes out of the outer cover 21, or when food splashes, first starts the food residue crushing program, and then lowers the working parameters of the driving component 23 until no food splashes out of the outer cover 21. In this way, the probability of secondary contamination of tableware caused by food splashing during the debris crushing process can be reduced, and the automatic spray cleaning operation after the secondary contamination of the tableware can be realized.

[0091] Preferably, the starting of the tableware spray cleaning program is specifically starting a quick wash program for spray cleaning of tableware.

[0092] Preferably, the starting of the drive component 23 and lowering of the working parameters of the drive component 23 are specifically: when the drive component 23 is started, the drive component 23 is controlled to operate according to the lowered new working parameter B, wherein the calculation formula of the new working parameter B is as follows: the new working parameter B = 1-0.1n × Z, or the new working parameter B = 1-0.1 n ×Z, where n is the number of times the food residue crushing program is restarted.

[0093] Example 5

[0094] like Figure 7 As shown, the difference between this embodiment and embodiment 2 is that the steps to be taken when it is determined in step S3 that food residues are splashed from the outer cover 21 toward the washing chamber 1 are different. The control method of this embodiment includes the following steps:

[0095] S1, start the food residue crushing program;

[0096] S2, start the driving component 23 to make the slag crushing component 22 rotate to crush the food residues, and start the identification module 3 at the same time or with a delay;

[0097] S3, determining whether there is food residue splashing from the outer cover 21 toward the washing chamber 1, if yes, proceeding to step S52, if no, proceeding to step S4;

[0098] S4, controlling the driving component 23 to operate according to the originally set working parameter Z until the food residue crushing program is finished;

[0099] S52, lowering the working parameters of the drive assembly 23 until no residue flies out of the outer cover 21, and recording the current working parameters of the drive assembly 23;

[0100] S62, turning off the drive assembly 23 and the identification module 3, and starting the tableware spray cleaning program;

[0101] S72, after the tableware spray cleaning program is completed, restart the food residue crushing program;

[0102] S82, start the driving component 23 and control the driving component 23 to work according to the current working parameters until the food residue crushing program is completed.

[0103] It can be seen that the control method of this embodiment, when food splashes during the debris crushing process, first lowers the working parameters of the drive component 23, records the current working parameters until no food splashes out of the outer cover 21, and then starts the food residue crushing program. When the food residue crushing program is restarted, the drive component 23 is controlled to work according to the recorded current working parameters. In this way, the working parameter adjustment efficiency of the drive component 23 can be improved, and the food residue crushing program can be avoided from being started multiple times. While the tableware is cleaned after secondary contamination, energy is saved, the time required for the entire debris crushing work is shortened, and efficiency is improved.

[0104] Preferably, the starting of the tableware spray cleaning program is specifically starting a quick wash program for spray cleaning of tableware.
