Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of dishwashers, and particularly relates to a control method for a dishwasher with a drying device, and a dishwasher adopting the control method. Background Art
[0002] A dishwasher is an automated device for automatically cleaning tableware such as bowls, chopsticks, plates, and dishes. With the improvement of people's living standards, dishwashers are used by more and more families. It can reduce the labor intensity of users, improve work efficiency, enhance cleanliness, and meet the comfortable living experience of users. The working principle of a dishwasher is that a motor drives a washing pump to make the washing liquid spray out from a sprayer under a certain pressure, forming a dense hot water flow in three-dimensional directions. The sprayer rotates due to the reaction force of the sprayed water, so that the washing liquid is evenly sprayed onto the tableware in the dishwasher, and the tableware is subjected to three-dimensional spraying and rinsing and brushing.
[0003] Existing dishwashers generally use a rotating spray arm to spray and wash tableware. After the washing cycle is over, the tableware is dried by high-temperature waste heat. After ceramic tableware, glass tableware, and stainless steel tableware are rinsed with hot water, the temperature of the tableware itself will be relatively high. After being placed for a period of time, the ceramic tableware, glass tableware, and stainless steel tableware will dry quickly.
[0004] However, in contrast, the drying rate of tableware such as chopsticks placed in a chopstick basket is relatively poor, and there are the following phenomena: In order to prevent tableware from passing through the bottom, the bottom net of the chopstick basket is generally set to be relatively dense, making it easy for water droplets to remain at the chopstick basket; at the same time, since chopsticks are generally made of materials such as wood and bamboo, after washing, the liquid on the chopsticks gathers downward due to gravity, and it is difficult to dry after being placed for a period of time. This results in that after the washing and drying cycle of the dishwasher is over, the chopsticks and the bottom net of the chopstick basket may still be in a wet state, and the wet chopstick basket and chopsticks are prone to breed bacteria again.
[0005] The above information disclosed in this background art is only used to increase the understanding of the background art of the present application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Invention
[0006] In view of the above problems in the prior art, the present invention provides a control method for a dishwasher with a drying device, which is beneficial to air-dry the tableware placed in the chopstick basket and ensure the dryness of the chopstick basket and the tableware inside after cleaning.
[0007] To achieve the above invention object, the present invention adopts the following technical solutions: A control method for a dishwasher with an air-drying device, the dishwasher having: a washing cavity, an air inlet formed on the cavity wall of the washing cavity, and an air-drying device provided outside the air inlet for air-drying the tableware placed in the chopstick basket, the chopstick basket being provided inside the air inlet; The control method includes the following steps: S10. After the washing program of the dishwasher ends, start the air-drying device so that the air-drying air flow flows out from the air inlet for blowing the water droplets in the chopstick basket off; S20. Start the drying device for drying the interior of the washing cavity; the air-drying device continues to blow air to the chopstick basket to accelerate the drying of the chopstick basket; S30. Turn off the air-drying device and turn off the drying device.
[0008] In some embodiments of the present application, the air-drying device has an air duct and a damper structure located in the air duct and capable of closing the air inlet; in step S10, it has: S11. Control the damper structure to open the air inlet so that the effective air inlet formed by enclosing the air duct and the damper structure reaches the maximum state, and then start the air-drying device to enter the direct blowing stage for the chopstick basket; S12. Control the damper structure to reciprocate to adjust the size of the effective air inlet and enter the strong blowing stage for the chopstick basket.
[0009] In some embodiments of the present application, the dishwasher further has a sensor for detecting the weight of the chopstick basket. Before the start of the washing program, the weight of the chopstick basket is detected as G0; after the end of the washing program, the weight of the chopstick basket is detected as G1; in step S11, when the weight of the chopstick basket decreases to (G0 + G1) / 2, control the damper structure to reciprocate and enter step S12.
[0010] In some embodiments of the present application, in step S12, when the weight of the chopstick basket decreases to (1 - m)G0 + mG1, enter step S20, where m = 0.2 to 0.3.
[0011] In some embodiments of the present application, in step S20, when the weight of the chopstick basket decreases to (1 - n)G0 + nG1, enter step S30 to turn off the air-drying device, where m = 0.1 to 0.04.
[0012] In some embodiments of the present application, in step S20, control the damper structure to reciprocate, and as the weight of the chopstick basket decreases, the reciprocating rotation speed of the damper structure increases.
[0013] In some embodiments of the present application, there is also a step S9 of determining whether to activate the air-drying device. The dishwasher has a sensor for detecting the weight of the chopstick basket. The weight of the empty chopstick basket is g0, and the first set weight is g1. Before the start of the washing program, the weight of the chopstick basket is detected as G0. If G0 ≥ g0 + g1, then the air-drying device is activated in step S10.
[0014] In some embodiments of the present application, if G0 < g0 + g1, then the air-drying device is not activated in the control method.
[0015] In some embodiments of the present application, the second set weight is g2, and the ratio of g2 to g1 is 3 to 5. If g0 + g1 ≤ G0 < g0 + g2, then in step S20, the air-drying device is in the off state. If G0 ≥ g0 + g2, then in step S20, the air-drying device is in the on state.
[0016] Based on the above control method of a dishwasher with an air-drying device, the present invention also provides a dishwasher using this control method, which is beneficial to air-dry the tableware placed in the chopstick basket and ensure the dryness of the chopstick basket and the tableware inside after cleaning.
[0017] A dishwasher uses the above control method to achieve the drying of the chopstick basket.
[0018] Compared with the prior art, the advantages and positive effects of the present invention are as follows: By setting an air-drying device, the chopstick basket and the tableware placed therein are air-dried. After the washing program of the dishwasher ends, the air-drying device is activated to blow off the water droplets in the chopstick basket, reducing the moisture in the chopstick basket. Then, the drying device is activated to dry the washing cavity, and at the same time, the air-drying device blows specifically on the chopstick basket to accelerate the evaporation of the moisture in the chopstick basket, realizing the air-drying of the tableware in the chopstick basket, ensuring the dryness of the chopstick basket and the tableware inside after cleaning, and avoiding the growth of bacteria.

[0027] See Figures 1 - 27, is an embodiment of a control method of a dishwasher with an air drying device proposed by the present invention, the dishwasher comprises: a washing chamber, a chopstick cage 20 and an air drying device 30, an air inlet 111 is provided on the wall of the washing chamber; the chopstick cage 20 is arranged inside the air inlet 111. The air drying device 30 is arranged outside the air inlet 111, and is used to air dry the tableware contained in the chopstick cage 20. By providing the air drying device 30, the chopstick cage 20 and the tableware placed therein are air dried.
[0028] In this embodiment, a control method of a dishwasher having an air drying device 30 includes the following steps: S10. After the washing program of the dishwasher is finished, the air drying device 30 is started so that the air drying air flows out from the air inlet 111 to blow off the water droplets in the chopstick cage 20; Specifically, after the washing process is completed, a large amount of water droplets are accumulated in the chopstick cage 20. By starting the air-drying device 30, the air-drying airflow blows off the water droplets on the chopstick cage 20, thereby reducing the moisture in the chopstick cage; the air-drying airflow blows on the chopstick cage 20 and the tableware in the chopstick cage 20, and also has the effect of drying the moisture adhering to the chopstick cage 20 and the chopsticks.
[0029] S20 starts the drying device (not shown) for drying the interior of the washing chamber; the air-drying device 30 continues to blow air to the chopstick cage 20 to speed up the drying of the chopstick cage 20; The drying device is started to dry the washing cavity, and at the same time, the air drying device 30 blows air to the chopstick cage 20 to accelerate the evaporation of water in the chopstick cage 20; the tableware in the chopstick cage 20 is air-dried, and the chopstick cage and the tableware inside are dried after cleaning to avoid the breeding of bacteria.
[0030] S30. Turn off the air drying device and the drying device.
[0031] In some embodiments of the present application, the air drying device 30 comprises an air duct 31 and a damper structure 32 disposed in the air duct 31, and the damper structure 32 can close the air inlet 111. In step S10, there are: S11. The rotary damper structure 32 opens the air inlet 111, so that the effective air outlet formed by the air duct 31 and the damper structure 32 is enclosed to the maximum state, and then the air drying device 30 is started to enter the direct blowing stage of the chopstick cage 20; Specifically, the air door structure 32 is rotated to open and close, and the air duct 31 and the air door structure 32 are surrounded to form an effective air outlet. During the process of the air door structure 32 rotating and opening, the effective air outlet gradually increases, so that the blowing range of the air drying airflow gradually increases. The effective air outlet is controlled to the maximum state, so that the blowing range of the airflow entering the washing chamber from the air inlet 111 is the largest, and the entire chopstick cage 20 can be blown to drop water.
[0032] S12. Control the reciprocating movement of the air door structure 30 to adjust the size of the effective air outlet, and enter the strong blowing stage for the chopstick basket 20; Specifically, when the air door structure 30 reciprocally rotates between the maximum state and the minimum state of the effective air outlet, the effective air outlet gradually changes between the maximum state and the minimum state, so that the blowing range of the air flow entering the washing cavity from the air inlet 111 gradually changes between the maximum and the minimum; when the total amount of air flow in the air duct 31 remains unchanged, the intensity of the air flow entering the washing cavity from the air inlet 111 changes, which is beneficial to blowing down the water droplets that have not been blown off during the direct blowing stage; at the same time, it is beneficial to air-dry the water adhered to the chopstick basket 20 and the chopsticks.
[0033] In some embodiments of the present application, the dishwasher further has a sensor for detecting the weight of the chopstick basket 20, preferably set as a pressure sensor. Before the washing program starts, the chopstick basket 20 and the tableware such as chopsticks inside are in a dry state, and the detected weight of the chopstick basket 20 is G0, where G0 is the sum of the weight of the chopstick basket 20 and the tableware inside it; after the washing program ends, the chopstick basket 20 and the tableware inside it are adhered with washing water, and the detected weight of the chopstick basket 20 is G1, and G1 is definitely greater than G0, where (G1 - G0) is the weight of the water carried by the chopstick basket 20 and the tableware inside it. In step S11, as the water droplets on the chopstick basket 20 drip, the weight of the chopstick basket 20 decreases; when half of the water carried by the chopstick basket 20 and the tableware inside it is removed, step S11 ends. At this time, there are no water droplets in the chopstick basket 20, and the weight of (G1 - G0) / 2 is the water covering the surface of the chopstick basket 20 and the tableware, or the water infiltrating into the chopsticks. At this time, the weight of the chopstick basket 20 is G0 + (G1 - G0) / 2, that is, (G0 + G1) / 2; when the weight of the chopstick basket 20 decreases to (G0 + G1) / 2, control the reciprocating movement of the air door structure 32 and enter step S12. For simplicity of expression, the water on the chopstick basket 20 refers to the water on the chopstick basket 20 and the tableware inside it, and the weight of the chopstick basket 20 is the sum of the weight of the chopstick basket 20 and the tableware inside it.
[0034] In some embodiments of the present application, in step S12, the water on the chopstick basket 20 and the tableware inside continues to decrease. When the weight of the chopstick basket 20 decreases to (1 - m)G0 + mG1, enter step S20, where m = 0.2 - 0.3. In the strong blowing stage of step S12, when the weight of the water carried by the chopstick basket 20 and the tableware inside it at the end of the washing program (G1 - G0) remains 20% - 30% of the remaining carried water, enter step S20, that is, in step S10, 70% - 80% of the water is removed by turning on the air drying device 30.
[0035] In some embodiments of the present application, in step S20, the weight of the chopstick cage 20 continues to decrease. When the weight of the chopstick cage 20 decreases to (1 - n)G0 + nG1, step S30 is entered to turn off the air drying device 30, where m = 0.1 - 0.04, and preferably, m = 0.07 - 0.04. In step S20, drying in the washing cavity is performed. While the chopstick cage 20 is being dried, it is also being air dried, which increases the evaporation of moisture on the chopstick cage 20 and is beneficial to increasing the drying efficiency of the chopstick cage 20. After the air drying device 30 is turned off, the moisture on the chopstick cage 20 can be evaporated by the residual heat of drying.
[0036] In some embodiments of the present application, in step S20, the air door structure 32 is controlled to reciprocate, so that the blowing range of the air flow entering the washing cavity from the air inlet 111 changes, and the intensity of the air flow entering the washing cavity from the air inlet 111 also changes; as the weight of the chopstick cage 20 decreases, the reciprocating rotation speed of the air door structure 32 is increased to increase the evaporation of moisture on the chopstick cage 20.
[0037] In some embodiments of the present application, step S9 for judging whether the air drying device 30 needs to be turned on is also included in the control method. When there are too few tableware such as chopsticks in the chopstick cage 20, there is less stored water in the chopstick cage 20 after the washing program, and the air drying device 30 does not need to be turned on; in the case where the number of tableware such as chopsticks in the chopstick cage 20 is large, the air drying device 30 definitely needs to be turned on. The weight of the empty chopstick cage 20 is detected as g0, and before the start of the washing program, the weight of the chopstick cage 20 is detected as G0, then G0 - g0 is the weight of the tableware in the chopstick cage 20. If G0 - g0 ≥ the first set weight g1, that is, G0 ≥ g0 + g1, then the air drying device is started in step S10. If G0 < g0 + g1, the air drying device 30 is not started in the control method.
[0038] In some embodiments of the present application, when the number of tableware in the chopstick cage 20 is within the intermediate range, it can be set that the air drying device 30 is only turned on in step S10, and after the end of S10, the air drying device 30 is turned off. The second set weight is g2, and the ratio of g2 to g1 is set to 3 - 5; if g0 + g1 ≤ G0 < g0 + g2, then in step S20, the air drying device 30 is in the off state; if G0 ≥ g0 + g2, then in step S20, the air drying device 30 is in the on state.
[0039] See Figures 1 - 26As shown in the figure, the drying device 30 of the dishwasher is described. The drying device 30 has an air duct 31 and a damper structure 32 provided in the air duct 31. The damper structure 32 can close the air inlet 111. By providing the drying device 30, the chopstick basket 20 and the tableware placed therein are dried; after the washing program of the dishwasher, the air flow is introduced into the washing cavity through the air inlet and blown to the chopstick basket 20. The air flow acts on the tableware placed in the chopstick basket 20 to drop the water droplets on the chopstick basket 20 and its internal tableware and accelerate evaporation, realizing the drying of the tableware in the chopstick basket 20, ensuring the dryness of the chopstick basket 20 and its internal tableware after cleaning, and avoiding the growth of bacteria. By providing the damper structure 30 for closing the air inlet 111, when drying, the damper structure 32 is opened to allow the drying gas to enter; under normal conditions, the damper structure 32 is in a closed state to prevent the washing water from splashing out through the air inlet 111 during the washing program.
[0040] In some embodiments of the present application, the damper structure 32 has a rotating shaft 321, a first sealing plate 322 and a second sealing plate 323 extending radially outward along the rotating shaft 321. The first sealing plate 322 and the second sealing plate 323 are arranged at intervals, and the first sealing plate 322 and the second sealing plate 323 cooperate with the air duct 31 to close the air inlet 111. By providing the rotating shaft 321, the first sealing plate 322 and the second sealing plate 323, the rotational movement of the damper structure 32 can be realized by rotating the rotating shaft 321, so as to close or open the air inlet 111 by the damper structure 32; the opening and closing operation of the damper structure 32 is simple.
[0041] In some embodiments of the present application, a first limiting plate 311 extending downward and outward is provided in the air duct 31. In the state where the damper structure 32 closes the air inlet 111, the first sealing plate 322 overlaps on the inner side of the first limiting plate 311. The first limiting plate 311 is provided in the air duct 31 near the air inlet 111, and the first limiting plate 311 is located at the upper part of the air duct 31. The first limiting plate 311 is provided to extend downward and outward, so that after the air flow in the air duct 31 reaches the first limiting plate 311, part of the air flow will be guided to flow upward and inward, expanding the blowing range of the gas and facilitating the gas to blow onto the entire chopstick basket 20; and in the state where the damper structure 32 closes the air inlet 111, the first sealing plate 322 overlaps on the inner side of the first limiting plate, so that during the washing program of the dishwasher, when water is sprayed onto the first limiting plate 311 at the air inlet 111, the water flow will flow downward along the first limiting plate 311.
[0042] In some embodiments of the present application, the first sealing plate 322 has a first sealing plate body 3221 and a first sealing edge 3222 fixedly provided at one end of the first sealing plate body 3221 away from the rotation axis 321. The first sealing edge 3222 can be hermetically lapped with the first limiting plate 311; the first sealing plate body 3221 and the first sealing edge 3222 are arranged on the same plane. By providing the first sealing edge 3222, it is beneficial to increase the sealing performance between the first sealing plate 322 and the first limiting plate 311, and increase the tightness after the air inlet 111 is closed; by arranging the first sealing plate body 3221 and the first sealing edge 3222 on the same plane, during the opening process of the air door structure 32, the first sealing plate 322 moves downward, and the gas in the air duct 31 flows out along the upper side of the first sealing plate 322; by providing the first sealing plate body 3221 and the first sealing edge 3222, it is beneficial to ensure the smooth flow of the air flow.
[0043] In some embodiments of the present application, a second limiting plate 312 extending downward and outward is provided in the air duct 31. Cooperating with the first limiting plate 311, a flared shape with a downward inclination at the lower end and an upward inclination at the upper end in the inward direction is formed near the air outlet 111, which is beneficial to the diffusion of the air flow after flowing into the washing cavity, and increases the air drying range. The second limiting plate 312 matches the second sealing plate 323. In the state where the air inlet 111 is closed, the second limiting plate 312 and the second sealing plate 323 are lapped on the second limiting plate 312. The second sealing plate 323 has a second sealing plate body 3231 and a folded edge 3232 bent and extended along one end of the second sealing plate body 3231 away from the rotation axis 321; in the state where the air door structure 32 closes the air inlet 111, the second sealing plate body 3231 is flush with the second limiting plate 312; so that during the washing process, after the water flow sprays onto the second limiting plate 312, it can flow down along the second limiting plate 312.
[0044] In some embodiments of the present application, the second sealing plate 322 further has a second sealing edge 3233 fixed on the folded edge 3232, and the second sealing edge 3233 is arranged parallel to the second sealing plate body 3231; when the air damper structure 32 closes the air inlet 111, the second sealing edge 3233 is located outside the second limiting plate 312. By providing the second sealing edge 3233, the sealing between the second sealing plate 322 and the second limiting plate 312 is realized, and the second sealing edge 3233 is arranged outside the second limiting plate 312, which is convenient for defining that the air damper structure 32 is closed in place; and the first sealing edge 3222 is arranged inside the first limiting plate 311. During the opening and closing process of the air damper structure 32, the first sealing plate 322 moves between the first limiting plate 311 and the second limiting plate 312. When the first sealing plate 322 reaches the inside of the second limiting plate 312, it is in the maximum open state.
