Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of dishwashers, and particularly relates to a dishwasher. 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 washing water 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 water spray, 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 ends, 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 the 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 very difficult to dry after being placed for a period of time. This results in that after the washing and drying cycle of the dishwasher ends, 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 very likely 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

[0039] See Figures 1 - 26, which is an embodiment of a washing machine proposed by the present invention. A dishwasher includes: a washing cavity (not shown in the figure), a chopstick basket 20, and a drying device 30. An air inlet 111 is formed on the cavity wall of the washing cavity; the chopstick basket 20 is arranged inside the air inlet 111. The drying device 30 is arranged outside the air inlet 111, and the drying device 30 is used for drying the tableware placed in the chopstick basket 20; the drying device 30 has an air duct 31 and a damper structure 32 arranged in the air duct 31, and 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, air is introduced into the washing cavity through the air inlet and blown to the chopstick basket 20, and the air 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 washing water from splashing out through the air inlet 111 during the washing program.
[0040] In some embodiments of the present application, refer to Figures 7 - 14 As shown, 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 rotating movement of the damper structure 32 can be realized through the rotation of 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 is lapped on the inner side of the first limiting plate 311. The first limiting plate 311 is arranged in the air duct 31 close to the air inlet 111, and the first limiting plate 311 is located in the upper part of the air duct 31. By arranging the first limiting plate 311 to extend downward and outward, 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, so that the blowing range of the gas is expanded, which is beneficial to the gas blowing 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 is lapped 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 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 the lower end inclined inward and the upper end inclined upward 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; in the state where 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 achieved, 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. The air duct 31 and the air damper structure 32 enclose an effective air outlet, and the effective air outlet is formed by enclosing the first limiting plate 311, the first sealing plate 322, and the left and right side edges of the air duct 31; by rotating the air damper structure 32, the distance between the first sealing plate 322 and the first limiting plate 311 changes, and the size of the effective air outlet changes.
[0045] In some embodiments of the present application, the included angle between the first limiting plate 311 and the second limiting plate 312 is 100° - 120°, and the included angle between the first sealing plate 322 and the second sealing plate 323 is the same as the included angle between the first limiting plate 311 and the second limiting plate 312. By controlling the rotation of the air damper structure 32, the rotation of the first sealing plate 322 between the first limiting plate 311 and the second limiting plate 312 can be realized, so that the included angle between the first sealing plate 322 and the first limiting plate 311 changes, and the size of the effective air outlet changes. It can be set that during the air drying process, the included angle between the first sealing plate 322 and the first limiting plate 311 is adjusted between 10° and the angle corresponding to the maximum state, so as to change the size of the effective air outlet, and further realize the change of the air flow intensity, which is beneficial to improving the air drying efficiency of the chopstick basket 20. Preferably, the included angle between the first sealing plate 322 and the first limiting plate 311 is controlled to be between 20° and 110°.
[0046] In some embodiments of the present application, the lower end of the effective air outlet is the first sealing plate 322, and the upper end is the first limiting plate 311. The first limiting plate 311 is inclined upward in the inward direction, and the first sealing plate 322 extends radially along the rotation axis 321. Therefore, the opening size of the effective air outlet gradually increases in the inward direction, realizing the diffusion of the air flow after entering the washing cavity and ensuring the air drying range.
[0047] In some embodiments of the present application, refer to Figures 13 - 17As shown, the air drying device 30 further includes a driving motor 34 for driving the damper structure 32 to rotate. A connecting sleeve 35 is provided between the output shaft 341 of the driving motor 34 and the rotating shaft 321 to realize the connection between the driving motor 34 and the rotating shaft 321. The connecting sleeve 35 is sleeved outside the output shaft 341. An installation hole 3211 is provided at the end of the rotating shaft 321. The installation hole 3211 is arranged to match the connecting sleeve 35, and the connecting sleeve 35 is installed in the installation hole 3211. Through the double-layer sleeving, the installation and fixation of the driving motor 34 and the rotating shaft 321 are realized.
[0048] In some embodiments of the present application, a limiting rib 351 protruding radially outward is provided on the connecting sleeve 35, and a limiting groove 3212 matching the limiting rib 351 is provided in the installation hole 3211. By providing the limiting rib 351 and the limiting groove 3212, the circumferential limitation between the connecting sleeve 35 and the rotating shaft 321 is realized, so that the torque transmitted to the connecting sleeve 35 can be transmitted to the rotating shaft 321 to realize the rotation of the damper structure 32. The output shaft 341 is a spline structure, and the inner cavity of the connecting sleeve 35 is arranged to match the output shaft 341, so that the output shaft 341 can transmit the torque to the connecting sleeve 35.
[0049] In some embodiments of the present application, a buckle 352 is provided on the sleeve wall of the connecting sleeve 35, and a clamping groove 3213 communicating with the installation hole 3211 is provided on the rotating shaft 321. The clamping groove 3213 is arranged to match the buckle 352. The buckle 352 has a buckle body 3521 that can be deformed radially, and a convex portion 3522 protruding radially outward is provided on the buckle body 3521. The convex portion 3522 is clamped in the clamping groove 3213. By providing the buckle 352 and the clamping groove 3213, the axial limitation between the connecting sleeve 35 and the rotating shaft 321 is realized, and the installation and connection between the connecting sleeve 35 and the rotating shaft 321 are firm. By providing the buckle body 3521 that can be deformed radially, when the connecting sleeve 35 is installed in the installation hole 3211, the convex portion 3522 fits against the sleeve wall of the connecting sleeve 35, so that the buckle body 3521 moves radially inward; after the convex portion 3522 enters the clamping groove 3213, the buckle body 3521 moves radially inward and resets.
[0050] In some embodiments of the present application, refer to Figures 7 - 11As shown in the figure, the air duct 31 includes an air duct body 315, an air outlet cavity 317 connected to the air outlet 111, and an air guiding pipe 316 connected between the air duct body 315 and the air outlet cavity 315. The end of the air outlet cavity 317 is installed at the air inlet 111. The air damper structure 32 is located in the air outlet cavity 315, and the first limiting plate 311 and the second limiting plate 312 are arranged in the air outlet cavity 315. The air guiding pipe 316 is inclined away from the air outlet 111 in the direction close to the air outlet cavity 315. First, it can increase the size of the air outlet cavity 315 in the inner and outer directions, facilitating the formation of a space for accommodating the air damper structure 32. Second, it can change the direction of the air flow, making the air flow direction flowing out from the air inlet 111 flow inward.
[0051] In some embodiments of the present application, the washing cavity has an openable and closable door body 11. The air drying device 30 is arranged in the door body 11. The door body 11 has a lining 115 and a door shell 116. The air drying device 30 is located between the lining 115 and the door shell 116.

[0060] In the following, a method for controlling a dishwasher according to the present embodiment 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.
[0061] 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.
[0062] S30. Turn off the air drying device and the drying device.
[0063] 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, it is opened and closed by rotating the damper structure 32. The air duct 31 and the damper structure 32 enclose to form an effective air outlet. During the process of the damper structure 32 rotating and opening, the effective air outlet gradually increases, so that the blowing range of the air flow for air drying gradually increases. The effective air outlet is controlled to the maximum state, so that the blowing range of the air flow entering the washing cavity from the air inlet 111 is the largest, and the whole chopstick cage 20 can be blown, and the water drops will drip down.
[0064] S12. Control the damper structure 30 to reciprocate to adjust the size of the effective air outlet and enter the strong blowing stage for the chopstick cage 20; Specifically, when the damper 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 the 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 drops that have not been blown off in the direct blowing stage; at the same time, it is beneficial to air-dry the moisture adhering to the chopstick cage 20 and the chopsticks.
[0065] In some embodiments of the present application, the dishwasher further has a sensor for detecting the weight of the chopstick cage 20, preferably set as a pressure sensor. Before the start of the washing program, the chopstick cage 20 and the tableware such as chopsticks inside are in a dry state, and the detected weight of the chopstick cage 20 is G0, where G0 is the sum of the weights of the chopstick cage 20 and the tableware therein; after the end of the washing program, the chopstick cage 20 and the tableware inside are adhered with washing water, and the detected weight of the chopstick cage 20 is G1, and G1 is definitely greater than G0, where (G1 - G0) is the weight of the water carried by the chopstick cage 20 and the tableware therein. In step S11, as the water drops on the chopstick cage 20 drip, the weight of the chopstick cage 20 decreases; when half of the water carried by the chopstick cage 20 and the tableware therein is removed, step S11 ends. At this time, there are no water drops in the chopstick cage 20, and the weight of (G1 - G0) / 2 is the moisture covering the surface of the chopstick cage 20 and the tableware or the moisture infiltrating into the chopsticks. At this time, the weight of the chopstick cage 20 is G0 + (G1 - G0) / 2, that is, (G0 + G1) / 2; when the weight of the chopstick cage 20 decreases to (G0 + G1) / 2, control the damper structure 32 to reciprocate and enter step S12. For simplicity of expression, the moisture on the chopstick cage 20 refers to the moisture on the chopstick cage 20 and the tableware inside, and the weight of the chopstick cage 20 is the sum of the weights of the chopstick cage 20 and the tableware inside.
[0066] In some embodiments of the present application, in step S12, the moisture on the chopstick holder 20 and the inner tableware continues to decrease. When the weight of the chopstick holder 20 decreases to (1 - m)G0 + mG1, step S20 is entered, where m = 0.2 to 0.3. In the strong blowing stage of step S12, at the end of the washing program, when the weight of the moisture carried by the chopstick holder 20 and the inner tableware therein is 20% - 30% of the remaining carried moisture, step S20 is entered. That is, in step S10, 70% - 80% of the moisture is removed by turning on the air drying device 30.
[0067] In some embodiments of the present application, in step S20, the weight of the chopstick holder 20 continues to decrease. When the weight of the chopstick holder 20 decreases to (1 - n)G0 + nG1, step S30 is entered, and the air drying device 30 is turned off, where m = 0.1 to 0.04, preferably, m = 0.07 to 0.04. In step S20, drying in the washing cavity is performed. While the chopstick holder 20 is being dried, it is also being air-dried, increasing the evaporation of the moisture on the chopstick holder 20, which is beneficial to increasing the drying efficiency of the chopstick holder 20. After the air drying device 30 is turned off, the moisture on the chopstick holder 20 can be evaporated by the residual heat of drying.
[0068] 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 holder 20 decreases, the reciprocating rotation speed of the air door structure 32 is increased to increase the evaporation of the moisture on the chopstick holder 20.
[0069] In some embodiments of the present application, the control method further includes step S9 of determining whether to turn on the air drying device 30. When there are too few tableware such as chopsticks in the chopstick holder 20, the water stored in the chopstick holder 20 after the washing program is less, and there is no need to turn on the air drying device 30; in the case where there are a large number of tableware such as chopsticks in the chopstick holder 20, it is certain that the air drying device 30 needs to be turned on. The weight of the empty chopstick holder 20 is detected as g0, and before the start of the washing program, the weight of the chopstick holder 20 is detected as G0. Then G0 - g0 is the weight of the tableware in the chopstick holder 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, then the air drying device 30 is not started in the control method.
[0070] In some embodiments of the present application, when the number of tableware in the chopstick holder 20 is within a middle range, it can be set that the air drying device 30 is only turned on in step S10, and after step S10 ends, 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 to 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.
[0071] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, for those of ordinary skill in the art, it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions required to be protected by the present invention.
