[0028] The second aspect of the present invention provides a control method for a dishwasher as described in the present invention, and the control method includes the following steps:

[0029] Obtain the sound pressure value when the spray assembly sprays the cleaning liquid;

[0030] Judge whether the sound pressure value when the spray assembly sprays the cleaning liquid is less than or equal to a preset value;

[0031] If so, control the descaling device to start, and the dishwasher enters the descaling mode.

[0032] Beneficial effects: Since the control method of the present invention is used to control the dishwasher of the present invention, the control method of the present invention has the same technical effects as the dishwasher, for specific reference to the above description, and will not be repeated here.

[0033] In some embodiments, the spraying assembly includes a liquid spraying pipe and a spraying arm. The liquid spraying pipe is connected to a water cup, and a washing pump is provided on the liquid spraying pipe. The spraying arm is communicated with the liquid outlet of the liquid spraying pipe, and a plurality of water spraying openings are provided on the spraying arm.

[0068] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0069] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0070] The following Figures 1 to 6 is used to describe the embodiments of the present invention.

[0071] As Figure 1 shown, according to an embodiment of the present invention, on the one hand, a dishwasher is disclosed, which includes an inner container 1, a spraying assembly 2, a sensor 3, and a descaling device 4. Among them, the inner container 1 is provided with a water cup 11, the spraying assembly 2 is arranged in the inner container 1, the spraying assembly 2 is connected to the water cup 11, the spraying assembly 2 is used for spraying cleaning liquid, the sensor 3 is arranged in the inner container 1, the sensor 3 is used for detecting the sound pressure value when the spraying assembly 2 sprays the cleaning liquid, the descaling device 4 is connected to the water cup 11, and when the sound pressure value detected by the sensor 3 when the spraying assembly 2 sprays the cleaning liquid is less than or equal to a preset value, the descaling device 4 is opened, and the dishwasher enters the descaling mode.

[0072] In the dishwasher of the present application, when the dishwasher is operating normally, the spraying assembly 2 extracts the cleaning liquid in the water cup 11 and sprays it onto the tableware in the dishwasher to achieve automatic cleaning. When the sound pressure value detected by the sensor 3 when the spraying assembly 2 sprays the cleaning liquid is less than or equal to the preset value, the descaling device 4 is turned on, and the dishwasher enters the descaling mode. The descaling device 4 transports the descaling liquid into the water cup 11, and the spraying assembly 2 extracts and sprays the cleaning liquid mixed with the descaling liquid in the water cup 11, thereby realizing descaling of the inner wall of the water cup 11 and the pipe wall of the spraying assembly 2. The sensor 3 provided in the present application can timely judge the scale formation situation in the dishwasher and thus timely control the descaling device 4 to turn on, avoiding damage and abnormal operation caused by scale accumulation in the dishwasher. During the descaling process, the descaling device 4 can automatically add the descaling liquid into the water cup 11 without manual operation by the user, improving the user experience.

[0073] It can be understood that when the dishwasher is operating normally and the sound pressure value detected by the sensor 3 when the spraying assembly 2 sprays the cleaning liquid is greater than the preset value, it indicates that the scale in the dishwasher has not reached the preset threshold; when the dishwasher enters the descaling mode, the sensor 3 continuously detects the sound pressure value when the spraying assembly 2 sprays the cleaning liquid. If the detected sound pressure value is greater than the preset value, it means that the scale in the dishwasher has been removed, and the descaling device 4 can be turned off as needed.

[0074] When the dishwasher is newly installed or has just been thoroughly cleaned and is operating, the sound pressure value generated when the spraying assembly 2 sprays the cleaning liquid is 40 dB to 50 dB. Therefore, if the preset value is set to be lower than 40 dB, it is possible to effectively judge whether there is scale in the dishwasher. For example, the preset value can be set to 35 dB, but it is not limited thereto.

[0075] Specifically, the sensor 3 can be a sound sensor.

[0076] As Figure 1 shown, in some embodiments, the sensor 3 is disposed on the side wall of the inner tank 1 and is disposed close to the spraying assembly 2.

[0077] The sensor 3 is disposed on the side wall of the inner tank 1, which is convenient for installation. The sensor 3 is disposed close to the spraying assembly 2, and the sound pressure value when the spraying assembly 2 sprays the cleaning liquid can be detected more clearly, improving the accuracy of the detection result of the sensor 3.

[0078] In some embodiments, the spraying assembly 2 includes a liquid spraying pipe 21 and a spraying arm 22. Among them, the liquid spraying pipe 21 is connected to the water cup 11, a washing pump 211 is provided on the liquid spraying pipe 21, the spraying arm 22 is communicated with the liquid outlet of the liquid spraying pipe 21, and a plurality of water spraying openings are provided on the spraying arm 22.

[0079] When the dishwasher is working normally, the washing pump 211 is turned on, and the cleaning liquid in the water cup 11 flows through the liquid spraying pipe 21 to the spray arm 22 and is ejected through multiple water spraying openings on the spray arm 22, realizing the automatic cleaning of tableware; when the dishwasher enters the descaling mode, the descaling device 4 inputs the descaling liquid into the water cup 11, the washing pump 211 is turned on, and the descaling liquid in the water cup 11 flows through the liquid spraying pipe 21 to the spray arm 22 and is ejected, thereby realizing the descaling of the water cup 11 and the spraying assembly 2.

[0080] It should be noted that before the dishwasher enters the descaling mode, the water in the water cup 11 can be drained first and then the descaling device 4 can be turned on to improve the descaling effect and avoid diluting the descaling liquid with the residual water in the water cup 11. Of course, in other embodiments, the water in the water cup 11 does not need to be drained in advance, and as the descaling progresses, the concentration of the descaling liquid in the water cup 11 will gradually increase.

[0081] As Figure 1 shown, in some embodiments, the descaling device 4 includes a descaling tank 41 and a descaling water path 42. Among them, the descaling tank 41 is used for storing the descaling liquid, one end of the descaling water path 42 is connected to the descaling tank 41, the other end of the descaling water path 42 is connected to the water cup 11, and a descaling pump 421 is provided on the descaling water path 42. When the sound pressure value detected by the sensor 3 when the spraying assembly 2 sprays the cleaning liquid is less than or equal to the preset value, the descaling pump 421 is turned on, and the descaling liquid flows into the water cup 11 through the descaling water path 42.

[0082] When the descaling device 4 needs to be turned on, the descaling pump 421 is turned on, and the descaling liquid in the descaling tank 41 flows into the water cup 11 through the descaling water path 42, thereby realizing the automatic addition of the descaling liquid into the water cup 11 and facilitating the automatic descaling operation of the dishwasher.

[0083] As Figure 1 shown, in some embodiments, the descaling device 4 further includes a storage container 43 and an addition pipeline 44. Among them, the storage container 43 is used for storing the descaling agent, the addition pipeline 44 is connected between the storage container 43 and the descaling tank 41, and a dispenser 441 is provided on the addition pipeline 44. The dispenser 441 is used for dispensing the descaling agent in the storage container 43 into the descaling tank 41, and the descaling agent dissolves in the descaling tank 41 to form the descaling liquid.

[0084] With the above settings, when the descaling device 4 is turned on, the dispenser 441 is turned on, and the dispenser 441 dispenses the descaling agent in the storage container 43 into the descaling tank 41 through the addition pipeline 44, and the descaling agent dissolves in the descaling tank 41 to form the descaling liquid to continuously provide the descaling liquid for the descaling process.

[0085] It should be noted here that there is water stored in the descaling tank 41, and the descaling agent can dissolve in the water in the descaling tank 41 to form the descaling liquid.

[0086] In some embodiments, the descaling device 4 further includes a liquid level detection structure disposed in the descaling tank 41. When the liquid level detection structure detects that the liquid level in the descaling tank 41 is equal to zero, the descaling pump 421 is turned off.

[0087] The provided liquid level detection structure can continuously detect the liquid level in the descaling tank 41. When the liquid level detection structure detects that the liquid level in the descaling tank 41 is equal to zero, the descaling pump 421 is turned off, and the entire descaling process ends.

[0088] Specifically, as Figure 2 shown, the liquid level detection structure can be a float 8. The float 8 is disposed in the descaling tank 41 and floats on the liquid surface. When the float 8 sinks to the bottom of the descaling tank 41, it indicates that the liquid level in the descaling tank 41 is equal to zero, and a signal can be sent to control the descaling pump 421 to turn off.

[0089] Of course, in other embodiments, the liquid level detection structure can also be a liquid level sensor 3. The liquid level sensor 3 is inserted into the descaling tank 41 and extends to the bottom of the descaling tank 41. When the liquid level detection structure fails to detect the liquid level, it indicates that the liquid level in the descaling tank 41 is equal to zero, and a signal can be sent to control the descaling pump 421 to turn off.

[0090] As Figure 1 shown, in some embodiments, the dishwasher further includes a water replenishing system 5. The water replenishing system 5 is connected to both the water cup 11 and the descaling tank 41 and is used to replenish water into the water cup 11 and the descaling tank 41.

[0091] The provided water replenishing system 5 can automatically replenish water to the water cup 11 and the descaling tank 41 to meet the normal working water requirements of the dishwasher and the water usage requirements in the descaling mode.

[0092] As Figure 1 shown, in some embodiments, the water replenishing system 5 includes a water inlet pipeline 51, a first water replenishing pipeline 52, a second water replenishing pipeline 53, and a control valve group 54. Among them, the first water replenishing pipeline 52 is connected to the water inlet pipeline 51 and the water cup 11, and the second water replenishing pipeline 53 is connected to the water inlet pipeline 51 and the descaling tank 41. When the water cup 11 needs to be replenished with water, the control valve group 54 conducts the water inlet pipeline 51 and the first water replenishing pipeline 52. When the descaling tank 41 needs to be replenished with water, the control valve group 54 conducts the water inlet pipeline 51 and the second water replenishing pipeline 53.

[0093] With the above settings, when the dishwasher is operating normally and the water cup 11 needs to be refilled, the control valve group 54 conducts the water inlet pipeline 51 and the first water replenishing pipeline 52. Water flows in from the water inlet pipeline 51, passes through the first water replenishing pipeline 52 and flows into the water cup 11 to automatically refill the water cup 11, meeting the normal washing water demand of the dishwasher. When the dishwasher is in the descaling mode and the descaling tank 41 needs to be refilled, the control valve group 54 conducts the water inlet pipeline 51 and the second water replenishing pipeline 53. Water flows in from the water inlet pipeline 51, passes through the second water replenishing pipeline 53 and flows into the descaling tank 41 to automatically refill the descaling tank 41, meeting the descaling water demand of the dishwasher.

[0094] As Figure 1 shown, in some embodiments, the control valve group 54 includes a water inlet valve 541 and a three-way valve 542. Among them, the water inlet valve 541 is arranged on the water inlet pipeline 51, and the three-way valve 542 is arranged at the connection of the water inlet pipeline 51, the first water replenishing pipeline 52 and the second water replenishing pipeline 53. When the water cup 11 needs to be refilled, the water inlet valve 541 opens and the three-way valve 542 conducts the water inlet pipeline 51 and the first water replenishing pipeline 52. When the descaling tank 41 needs to be refilled, the water inlet valve 541 opens and the three-way valve 542 conducts the water inlet pipeline 51 and the second water replenishing pipeline 53.

[0095] With the above settings, when the water cup 11 needs to be refilled, the water inlet valve 541 opens and the three-way valve 542 conducts the water inlet pipeline 51 and the first water replenishing pipeline 52. Water flows in from the water inlet pipeline 51, and successively passes through the water inlet valve 541, the three-way valve 542 and the first water replenishing pipeline 52 and flows into the water cup 11. When the descaling tank 41 needs to be refilled, the water inlet valve 541 opens and the three-way valve 542 conducts the water inlet pipeline 51 and the second water replenishing pipeline 53. Water flows in from the water inlet pipeline 51, and successively passes through the water inlet valve 541, the three-way valve 542 and the second water replenishing pipeline 53 and flows into the descaling tank 41.

[0096] Since the water inlet valve 541 and the three-way valve 542 are prior arts, they will not be elaborated in this embodiment.

[0097] As an alternative implementation, the control valve group 54 can also be set to include a water inlet valve 541, a first valve and a second valve. The water inlet valve 541 is arranged on the water inlet pipeline 51, the first valve is arranged on the first water replenishing pipeline 52, and the second valve is arranged on the second water replenishing pipeline 53. When the water cup 11 needs to be refilled, the water inlet valve 541 and the first valve open. When the descaling tank 41 needs to be refilled, the water inlet valve 541 and the second valve open.

[0098] As Figure 1 shown, in some embodiments, the water replenishing system 5 further includes a flow meter 55, and the flow meter 55 is arranged on the water inlet pipeline 51.

[0099] The provided flow meter 55 can monitor and count the water flowing through the water inlet pipe 51 to timely understand the water consumption.

[0100] Specifically, the flow meter 55 is arranged downstream of the water inlet valve 541. When the water inlet valve 541 is closed, the water flow can be cut off to prevent the water from flowing to the flow meter 55.

[0101] In some embodiments, the dishwasher further includes a drainage system 6. The drainage system 6 is connected to the water cup 11 and is used to drain the solution in the water cup 11.

[0102] The provided drainage system 6 can empty the solution in the water cup 11 after the dishwasher finishes washing or descaling to keep the inside of the dishwasher dry.

[0103] The composition of the descaling agent can be citric acid. After citric acid (C6H8O7) reacts with the water scale, it generates CaC6H5O7 and MgC6H5O7 that are easily soluble in water, and will be discharged from the water cup 11 together by the drainage pump 62 after the descaling is completed.

[0104] Such as Figure 1 As shown, in some embodiments, the drainage system 6 includes a drainage pipe 61. The drainage pipe 61 is communicated with the bottom of the water cup 11. A drainage pump 62 is arranged on the drainage pipe 61. When the water cup 11 needs to be drained, the drainage pump 62 is turned on to conduct the drainage pipe 61.

[0105] When drainage is required, the drainage pump 62 is turned on, and the water in the water cup 11 flows out through the drainage pipe 61, connecting the drainage pipe 61 and the bottom of the water cup 11, which is beneficial to emptying the water in the water cup 11.

[0106] In addition to the above arrangements, the dishwasher further includes a bowl basket 7. The bowl basket 7 is used to place tableware. The bowl basket 7 is arranged in the inner container 1, and the bowl basket 7 is oppositely arranged with a plurality of water spray nozzles of the spray arm 22, so that the cleaning liquid can be sprayed from the spray arm 22 to the bowl basket 7 through the spray arm 22 to realize the rinsing of the tableware in the bowl basket 7.

[0107] For the convenience of understanding the dishwasher of the present invention, the following is an introduction to its usage process in combination with the attached Figure 1 and attached Figure 2 , as follows:

[0108] When the dishwasher is working normally, the washing pump 211 is turned on. The cleaning liquid in the water cup 11 flows through the liquid spraying pipe 21 to the spray arm 22 and is sprayed out through a plurality of water spray nozzles on the spray arm 22 to realize the automatic cleaning of the tableware in the bowl basket 7. When the washing is finished, the washing pump 211 is turned off, and the drainage pump 62 is turned on. The water in the water cup 11 is discharged through the drainage pipe 61 to keep the water cup 11 dry.

[0109] When the water cup 11 needs to be refilled, the water inlet valve 541 is opened, the three-way valve 542 conducts the water inlet pipeline 51 and the first water replenishing pipeline 52, water flows in from the water inlet pipeline 51, and successively passes through the water inlet valve 541, the flow meter 55, the three-way valve 542, and the first water replenishing pipeline 52 to flow into the water cup 11, realizing automatic water replenishment for the water cup 11.

[0110] When the dishwasher is working properly, the sensor 3 continuously detects the sound pressure value when the spray assembly 2 sprays the cleaning liquid. When the detected sound pressure value when the spray assembly 2 sprays the cleaning liquid is less than or equal to the preset value, the dispenser 441, the descaling pump 421, and the washing pump 211 are turned on. The descaling agent in the storage container 43 is dispensed into the descaling tank 41 through the dispenser 441. The descaling agent dissolves in water in the descaling tank 41 to form a descaling liquid. The descaling liquid flows into the water cup 11 through the descaling water path 42. At the same time, the washing pump 211 pumps the descaling liquid in the water cup 11 into the spray pipe 21, and sprays it out through a plurality of spray nozzles after passing through the spray arm 22, thereby realizing descaling of the water cup 11 and the spray assembly 2.

[0111] During the descaling process, when the liquid level detection structure detects that the liquid level in the descaling tank 41 is low, the water inlet valve 541 is opened, and the three-way valve 542 conducts the water inlet pipeline 51 and the second water replenishing pipeline 53. Water flows in from the water inlet pipeline 51, and successively passes through the water inlet valve 541, the flow meter 55, the three-way valve 542, and the second water replenishing pipeline 53 to flow into the descaling tank 41, realizing automatic water replenishment for the descaling tank 41.

[0112] During the descaling process, the sensor 3 continuously detects the sound pressure value when the spray assembly 2 sprays the cleaning liquid. When the detected sound pressure value when the spray assembly 2 sprays the cleaning liquid is greater than the preset value, it indicates that the descaling is completed. The dispenser 441 is closed, and the descaling pump 421 is maintained in operation until the liquid level detection structure detects that the liquid level in the descaling tank 41 is zero. Then the descaling pump 421 is closed, the drain pump 62 is opened, and the water in the water cup 11 is discharged through the drain pipeline 61, and the dishwasher ends the descaling mode.

[0113] As Figures 3 to 5 shown, according to an embodiment of the present invention, on the other hand, a control method for a dishwasher as described in the present invention is disclosed. The control method includes the following steps:

[0114] Obtain the sound pressure value when the spray assembly 2 sprays the cleaning liquid;

[0115] Judge whether the sound pressure value when the spray assembly 2 sprays the cleaning liquid is less than or equal to the preset value;

[0116] If so, control the descaling device 4 to start, and the dishwasher enters the descaling mode.

[0117] Since the control method of the present invention is used to control the dishwasher of the present invention, the control method of the present invention has the same technical effects as the dishwasher. For details, please refer to the above description and will not be elaborated here.

[0118] It should be noted that the specific structure of the dishwasher described herein in this application has been introduced in detail above and will not be elaborated in this embodiment.

[0119] In some embodiments, if so, control the descaling device 4 to start, and the dishwasher enters the descaling mode, including: if so, control the descaling pump 421 and the washing pump 211 to start, and the descaling liquid flows into the water cup 11 through the descaling waterway 42, and the descaling liquid in the water cup 11 is sprayed out through the liquid spraying pipe 21, the spray arm 22 and the water spraying port in sequence.

[0120] Through the above settings, the inner wall of the water cup 11 can be descaled when the descaling liquid flows into the water cup 11, and at the same time, the descaling liquid in the water cup 11 flows through the liquid spraying pipe 21, the spray arm 22 and the water spraying port in sequence and is sprayed out, so as to realize the descaling of the inner walls of the liquid spraying pipe 21 and the spray arm 22.

[0121] In some embodiments, after if so, control the descaling device 4 to start and the dishwasher enters the descaling mode, it includes:

[0122] Judge whether the sound pressure value when the spraying component 2 sprays the cleaning liquid is greater than a preset value;

[0123] If so, control the dispenser 441 to close, and control the descaling pump 421 to keep running for a preset time t so as to empty the descaling liquid in the descaling tank 41.

[0124] When it is judged that the sound pressure value when the spraying component 2 sprays the cleaning liquid is greater than the preset value, it means that the scale in the dishwasher has been removed. Control the dispenser 441 to close to stop putting the descaling agent into the descaling tank 41, and control the descaling pump 421 to keep running for the preset time t to empty the descaling liquid in the descaling tank 41 to keep the inside of the descaling tank 41 dry.

[0125] In some embodiments, the descaling pump 421 keeps running for the preset time t to empty the descaling liquid in the descaling tank 41, including:

[0126] Obtain the liquid level in the descaling tank 41;

[0127] Judge whether the liquid level in the descaling tank 41 is zero;

[0128] If so, control the descaling pump 421 to close.

[0129] By obtaining the liquid level in the descaling tank 41 and judging the liquid level in the descaling tank 41, if the liquid level in the descaling tank 41 is zero, it means that the descaling liquid in the descaling tank 41 has been emptied, control the descaling pump 421 to close, and the dishwasher ends the descaling mode.

[0130] That is to say, the preset time t is specifically the time when the descaling liquid in the descaling tank 41 is emptied, which is set as required and not limited in this embodiment. For example, after the dispenser 441 is controlled to close, the descaling pump 421 runs for 15 minutes before emptying the descaling liquid in the descaling tank 41, then the preset time t is 15 minutes.

[0131] In some embodiments, the preset value is 35 dB.

[0132] If the spray assembly 2 is blocked due to scale accumulation in the dishwasher, the sound pressure value generated by the spray of the spray assembly 2 will gradually decrease. If it decreases below 35 dB, it is determined that the scale accumulation is relatively serious and will affect the washing effect of the dishwasher. At this time, the descaling device 4 is turned on and the dishwasher enters the descaling mode.

[0133] It can be understood that when the dishwasher is newly installed or has just been thoroughly cleaned, the sound pressure value generated when the spray assembly 2 sprays the cleaning liquid is 40 dB - 50 dB. Therefore, by setting the preset value to 35 dB, it can effectively determine whether there is scale in the dishwasher.

[0134] Of course, in other embodiments, the preset value can be set as required and is not limited to this embodiment. For example, the preset value can also be set to 36 dB, 34 dB, 33 dB or 32 dB, etc.

[0135] As Figure 6 shown, according to an embodiment of the present invention, on the other hand, a control device 100 for implementing the control method of the dishwasher of the present invention is disclosed. The control device 100 includes an acquisition module 101, a judgment module 102 and a control module 103. The acquisition module 101 is used to acquire the sound pressure value when the spray assembly 2 sprays the cleaning liquid. The judgment module 102 is used to judge whether the sound pressure value when the spray assembly 2 sprays the cleaning liquid is less than or equal to the preset value. The control module 103 is used to control the descaling device 4 to turn on.

[0136] Since the control device 100 of the present invention is used to implement the control method of the dishwasher of the present invention, it has the same technical effects as the control method of the dishwasher. For specific details, please refer to the above description and will not be repeated here.

[0137] According to an embodiment of the present invention, on the other hand, a computer-readable storage medium is disclosed. The computer-readable storage medium stores computer instructions, and when the computer instructions are executed, the control method of the dishwasher of the present invention is executed.

[0138] Since the computer instructions stored in the computer-readable storage medium of the present invention execute the control method of the dishwasher of the present invention when executed, it has the same technical effects as the control method of the dishwasher. For specific details, please refer to the above description and will not be repeated here.

[0139] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
