[0043] In one embodiment of the present application, a dishwasher is provided for washing dishes. The dishwasher comprises the dish rack 100, the visual component and the processing component in any embodiment of the present application, and also comprises an inner tank with a cleaning space, wherein the dish rack 100 and the visual component are placed in the cleaning space.

[0044] See also Figures 1 to 4 , Figures 1 to 4 FIG. 1 shows a structural schematic diagram of a bowl rack 100 in the first embodiment of the present application. The bowl rack 100 provided in the first embodiment of the present application is used to hold tableware. Figure 1As shown, the bowl rack 100 includes a frame 110 and a lifting support rod 120 connected to the bottom surface 111 of the frame 110. The bowl rack 100 includes a holding space 140 enclosed by the frame 110 and open at the top. The lifting support rod 120 is movably connected to the frame 110, so that the height of the lifting support rod 120 protruding from the bottom surface 111 of the frame 110 and extending into the holding space 140 is adjustable. Therefore, by adjusting the height of the lifting support rod 120 extending into the holding space 140, it can be adapted to tableware of different types and specifications, making the tableware placement method more flexible during the use of the bowl rack 100, thereby improving the cleaning efficiency and convenience of the dishwasher and meeting the user's personalized needs for the type and placement of tableware.

[0045] The visual component is disposed toward the holding space 140 and is used to capture tableware information in the holding space 140, so as to obtain the placement position, type and size of the tableware through the visual component, thereby providing a basis for adjusting the lifting support rod 120. It is understandable that the visual component can be any publicly available camera that can obtain tableware information.

[0046] The processing component is electrically connected to the visual component and the lifting support rod 120. The processing component is used to receive and process the tableware information obtained by the visual component, and drive the lifting support rod 120 to move relative to the frame 110 to adjust the height according to the tableware information, so that when the tableware is placed in the holding space 140, the corresponding lifting support rod 120 automatically rises to support the tableware without manual adjustment, thereby improving the adaptability of the dish rack 100 while taking into account the degree of automation of the dishwasher.

[0047] In this embodiment, if Figure 2 As shown, the lifting support rods 120 are distributed in a matrix on the bottom surface 111 of the frame 110, so that the processing component can position the tableware according to the tableware information, and then it is convenient to control the lifting support rods 120 at the corresponding positions according to the tableware information.

[0048] like Figure 3 As shown, in one embodiment, the bowl rack 100 also includes a driving member 150, each lifting support rod 120 is connected to a driving member 150, and the driving member 150 is transmission-connected to the corresponding lifting support rod 120 to drive the lifting support rod 120 to move relative to the frame 110, and each driving member 150 is independently controlled by the processing component, so that the processing component can independently control each lifting support rod 120, so that after the tableware is put in, the processing component only controls the lifting support rod 120 at the corresponding position to rise.

[0049] like Figure 3 and Figure 4As shown, in one embodiment, the bowl rack 100 further includes a transmission gear 161, and the peripheral surface of the lifting support rod 120 is provided with teeth 121 extending along its own axial direction, and the transmission gear 161 is meshed and connected to the teeth 121, and the driving member 150 drives the transmission gear 161 to rotate in a positive or reverse direction. Positive and reverse refer to clockwise or counterclockwise, which only means that the driving member 150 can drive the transmission gear 161 to rotate in two opposite directions, and is not limited. And the transmission gear 161 rotates to drive the lifting support rod 120 to move relative to the frame 110 along its own axial direction. When the transmission gear 161 rotates in the positive and reverse directions, the lifting support rod 120 moves in the reverse direction. For example, when the transmission gear 161 rotates the lifting support rod 120 forward to rise, the transmission gear 161 rotates the lifting support rod 120 in the reverse direction to descend, thereby realizing that the corresponding lifting support rod 120 is driven to rise and fall by the driving member 150. Vice versa.

[0050] like Figure 3 and Figure 4 As shown, in one embodiment, the bowl rack 100 further includes a bracket 162 connected to the frame 110, the bracket 162 includes a connecting portion 1621 and an extending portion 1622, and the driving member 150 is connected to the connecting portion 1621, so that the driving member 150 maintains a fixed position relative to the frame 110 and does not move relatively. The extending portion 1622 extends along the circumference of the lifting support rod 120 and surrounds the lifting support rod 120, so that the fixed bracket 162 plays a certain guiding role in the up and down movement of the lifting support rod 120, and avoids the lifting support rod 120 tilting to cause the meshing transmission of the transmission gear 161 and the teeth 121 to be unstable.

[0051] See also Figure 4 In one embodiment, the bottom surface 111 of the frame 110 includes a plurality of connecting rods 112 staggered in a horizontal and vertical direction, and through holes 1121 are provided at staggered positions of some connecting rods 112. The lifting support rods 120 are passed through the through holes 1121 to move up and down relative to the frame 110 to adjust the height. Figure 4 As shown, a limiting portion 122 having a diameter larger than that of the through hole 1121 is provided at the top of the lifting support rod 120 to prevent the lifting support rod 120 from excessively descending and separating from the frame 110 .

[0052] Combination Figure 5 As shown, Figure 5 The diagram shows a partial structural diagram of the bowl rack 100 in the second embodiment of the present application. The difference between this embodiment and the first embodiment of the present application is that the driving member 150 is a telescopic cylinder, one end of which is fixedly connected to the frame 110, and the other end is connected to the lifting support rod 120, and the telescopic direction of the telescopic cylinder is parallel to the axial direction of the lifting support rod 120. When the telescopic cylinder is extended or retracted, the lifting support rod 120 is driven to move up and down. Figure 5As shown, when the telescopic rod is shortened, the lifting support rod 120 moves upward and the height increases, and when the telescopic rod is extended, the lifting support rod 120 moves downward and the height decreases.

[0053] Combination Figure 6 As shown, Figure 6 The diagram shows a partial structural diagram of the bowl rack 100 in the third embodiment of the present application. The difference between this embodiment and the second embodiment of the present application is that the bowl rack 100 further includes a fixed support rod 130 connected to the bottom surface 111 of the frame 110. The fixed support rod 130 is fixedly connected to the frame 110 and partially protrudes from the bottom surface 111 of the frame 110 to extend into the storage space 140. The fixed support rod 130 and the lifting support rod 120 are arranged in a matrix on the bottom surface 111 of the frame 110. Figure 6 In the illustrated embodiment, the fixed support rods 130 are concentrated on one side of the bottom surface 111, so that tableware adapted to the fixed support rods 130 can be placed in the concentrated area of ​​the fixed support rods 130, and other tableware can be placed in the area where the lifting support rods 120 are located, thereby improving the adaptability of the bowl rack 100 while reducing the production cost of the bowl rack 100.

[0054] Combination Figure 7 and Figure 8 As shown, Figure 7 and Figure 8 A partial structural schematic diagram of the bowl rack 100 in the fourth embodiment of the present application is shown. The difference between this embodiment and the second embodiment of the present application is that the bowl rack 100 also includes an air intake duct, and the telescopic cylinder is connected to and controlled by the air intake duct. The telescopic cylinder is telescoped and expanded with the air pressure in the air intake channel, and the air pressure in the air intake duct is controlled by the processing component, so that the processing component adjusts the telescopic cylinder connected to the air intake channel by adjusting the air pressure in the air intake channel, thereby adjusting the height of the corresponding lifting support rod 120.

[0055] In such Figure 7 and Figure 8 In the embodiment shown, there are multiple air inlet channels, each lifting support rod 120 is connected to an air inlet channel, and multiple air inlet channels are arranged to cross but not connect. In this embodiment, there are two air inlet channels, namely a first air inlet channel 170a and a second air inlet channel 170b. Figure 8 As shown, the first air inlet passage 170a and the second air inlet passage 170b are arranged crosswise. Figure 7 As shown, there is a height difference in the axial direction of the lifting support rod 120 so that the two are not connected.

[0056] like Figure 8As shown, the path of the first air inlet channel 170a is indicated by a bold dotted line, and its structure is bent, connecting multiple lifting support rods 120 that are staggered horizontally and vertically, so that after the telescopic cylinder connected to the first air inlet channel 170a is driven, the corresponding lifting support rods 120 form placement areas with different widths to adapt to different tableware placement requirements. Similarly, the path of the second air inlet channel 170b is also bent, connecting multiple lifting support rods 120 that are staggered horizontally and vertically, so that after the telescopic cylinder connected to the second air inlet channel 170b is driven, the corresponding lifting support rods 120 form placement areas with different widths to adapt to different tableware placement requirements.

[0057] Combination Fig. 9 and Fig.10 As shown, Fig. 9 and Fig.10 The diagram shows a partial structural diagram of the bowl rack 100 in the fifth embodiment of the present application. The difference between this embodiment and the first embodiment of the present application is that the bowl rack 100 also includes a connecting seat 181 with a liquid storage cavity 1811 at the bottom, the connecting seat is fixedly connected to the frame 110, the lifting support rod 120 is hollow inside and has a hole at the bottom that connects the inside and outside of the lifting support rod 120, and the bowl rack 100 also includes a connecting pipe 182 partially arranged inside the lifting support rod 120, the bottom end of the connecting pipe 182 is fixedly connected to the connecting seat 181, and the top end of the connecting pipe 182 is located inside the lifting support rod 120, and The top of the connecting tube 182 is in sealed contact with the inner wall of the lifting support rod 120 to enclose the inner wall of the lifting support rod 120 to form a pressure-changing chamber 183. When the pressure in the pressure-changing chamber 183 changes, the connecting tube 182 and the lifting support rod 120 can be driven to move relative to each other. The connecting tube 182 is provided with a liquid flow hole 1821 arranged along its own axis to connect the liquid storage chamber 1811 and the pressure-changing chamber 183, so that the fluid in the liquid storage chamber 1811 and the pressure-changing chamber 183 can flow back and forth, thereby changing the pressure in the pressure-changing chamber 183, and then driving the lifting support rod 120 to move relative to the connecting tube 182. Fig.10 As shown, when the fluid in the transformer chamber 183 increases, the volume of the transformer chamber 183 will increase. Since the bottom end of the connecting pipe 182 is connected to the fixed connecting seat 181, the transformer chamber 183 will drive the lifting support rod 120 to move upward and increase its height. When the fluid in the transformer chamber 183 decreases, the lifting support rod 120 will descend under the action of gravity, so that the volume of the transformer chamber 183 will decrease.

[0058] In such Fig. 9 and Fig.10In the illustrated embodiment, the driving member 150 is used to drive the fluid in the liquid storage chamber 1811 to flow to the pressure-changing chamber 183. The bowl rack 100 also includes an impeller 184 located in the liquid flow hole 1821 and controlled by the driving member 150. When the impeller 184 rotates, it can drive the fluid in the liquid storage chamber 1811 to flow to the pressure-changing chamber 183, so that when the fluid in the pressure-changing chamber 183 increases, the volume of the pressure-changing chamber 183 will increase. Since the bottom end of the connecting tube 182 is connected to the fixed connecting seat 181, the pressure-changing chamber 183 will drive the lifting support rod 120 to move upward and increase its height.

[0059] In such Fig. 9 and Fig.10 In the illustrated embodiment, the bowl rack 100 further includes a reset elastic member 185, the connecting tube 182 includes a tube body 1822 and a sealing portion 1823 protruding from the circumference of the tube body 1822, the tube body 1822 passes through the hole at the bottom of the lifting support rod 120, so that the sealing portion 1823 is located at the top of the tube body 1822, and the sealing portion 1823 is sealed and slidably connected to the inner wall of the lifting support rod 120, the reset elastic member 185 is sleeved on the outer periphery of the tube body 1822 and the two ends are respectively abutted against the sealing portion 1823 and the bottom of the lifting support rod 120, and the reset elastic member 185 has a tendency to drive the sealing portion 1823 away from the bottom of the lifting support rod 120, so that when the driving member 150 stops working, the impeller 184 stops rotating, and the fluid in the pressure variable chamber 183 will flow back to the liquid storage chamber 1811 under the action of gravity. At this time, under the action of the gravity of the lifting support rod 120 itself and the reset elastic member 185, the lifting support rod 120 moves down and resets. It can be understood that the fluid can be either a liquid or a gas. In this embodiment, the fluid is a liquid.

[0060] Combination Fig.11 and Fig.12 As shown, Fig.11 and Fig.12 A partial structural schematic diagram of the bowl rack 100 in the sixth embodiment of the present application is shown. The difference between this embodiment and the fifth embodiment of the present application is that the connecting seat 181 includes a high-pressure chamber 191 and a low-pressure chamber 192 with different pressures, wherein the fluid pressure in the high-pressure chamber 191 is higher than the fluid pressure in the low-pressure chamber 192, and the fluid pressure in the high-pressure chamber 191 is not lower than the pressure when the fluid in the variable pressure chamber 183 is full, and the fluid pressure in the low-pressure chamber 192 is not higher than the pressure when the variable pressure chamber 183 is empty.

[0061] like Fig.12As shown, the bowl rack 100 also includes a valve body 193, which is connected between the high-pressure chamber 191 and the liquid flow hole 1821, and between the low-pressure chamber 192 and the liquid flow hole 1821. The valve body 193 is rotatably connected to the connecting pipe 182, and the driving member 150 is used to drive the valve body 193 to rotate, and the valve body 193 rotates to make the liquid flow hole 1821 selectively connected to the high-pressure chamber 191 and the low-pressure chamber 192, so that when the valve body 193 rotates to Fig.12 When the valve body 193 is in the position shown, the liquid flow hole 1821 is connected to the high pressure chamber 191. At this time, the pressure in the high pressure chamber 191 is higher than the pressure in the pressure changing chamber 183. Under the action of pressure, the fluid flows through the valve body 193 and the liquid flow hole 1821 to the pressure changing chamber 183, so that the pressure in the pressure changing chamber 183 increases and the volume increases. At this time, the pressure changing chamber 183 will drive the lifting support rod 120 to move upward and increase in height. When the valve body 193 rotates 180°, the liquid flow hole 1821 will be connected to the low pressure chamber 192. At this time, the pressure in the low pressure chamber 192 is lower than the pressure in the pressure changing chamber 183. Under the action of pressure, the fluid flows through the liquid flow hole 1821 and the valve body 193 to the low pressure chamber 192, so that the pressure in the pressure changing chamber 183 decreases. Under the action of the gravity of the lifting support rod 120 and the reset elastic member 185, the lifting support rod 120 moves downward and resets.

[0062] In one embodiment, the high-pressure chamber 191 and the low-pressure chamber 192 of each connection seat 181 are arranged in parallel and are parallel to any connection rod 112. The connection pipe 182 corresponding to the lifting support rod 120 connected to the connection rod 112 is connected to the connection seat 181 to reduce the cost of maintaining the pressure in the connection seat 181 and avoid the high cost caused by each lifting support rod 120 corresponding to a connection seat 181. However, it can be understood that since the driving member 150 and the valve body 193 are independently controlled, the lifting support rod 120 can be independently controlled even if connected to the same connection seat 181. A pressure pump 194 is provided between the high-pressure chamber 191 and the low-pressure chamber 192 to keep the fluid pressure in the high-pressure chamber 191 and the low-pressure chamber 192 within a preset range.

[0065] In one of the embodiments, in step “S20: the processing component controls the lifting support rod 120 located at the corresponding position of the tableware to adjust the height to support the tableware according to the tableware information”, the height of the lifting support rod 120 extending into the holding space 140 is 3 / 4 of the height of the tableware, so that the tableware is supported or clamped by the lifting support rod 120.

[0066] In one of the embodiments, the step "S20: the processing component controls the lifting support rod 120 located at the corresponding position of the tableware to adjust the height to support the tableware according to the tableware information" includes the following steps: S21: determine the position, type and state of the tableware. S22: If the tableware is an inverted cup body, adjust the tableware covering position or the lifting support rod 120 around the tableware to adjust the height. When the tableware is an inverted cup body, the surrounding lifting support rods 120 can be clamped to fix the cup body, and the lifting support rods 120 at the cup body covering position can be raised to directly support the cup body. S23: If it is other types and states of tableware, adjust the height of the lifting support rods 120 around the tableware, for example, if the tableware is a plate, bowl, etc., so as to clamp the tableware through the surrounding lifting support rods 120 to achieve support for the tableware.
