Description

Technical Field

[0001] The invention belongs to the technical field of kitchen electrical appliances, and in particular, relates to an embedded dishwasher and a control method thereof. Background Art

[0002] Built-in dishwashers need to be placed inside kitchen cabinets to reduce space occupation. To ensure that the dishwasher can be freely embedded in the kitchen cabinet, a certain gap must be reserved between the side wall of the dishwasher and the kitchen cabinet. The noise generated by the dishwasher when working will leak out from the gap, increasing the noise transmitted from the dishwasher to the external environment, giving users a poor user experience.

[0003] The existing noise reduction solutions for built-in dishwashers are mainly: 1. Add a damping layer to the inner tank to reduce the noise generated by the vibration of the inner tank sheet metal. However, adding a damping layer to the inner tank can only reduce the noise generated by the local jet hitting the inner tank during washing, and cannot achieve noise reduction for noise sources, such as washing pumps, other functional motors or transmission structures. Noise reduction cannot be achieved. 2. Add a rubber pad between the motor and the connection position to reduce the noise when the motor is running. However, it can only be applied to occasions with low vibration amplitude and vibration frequency, and cannot achieve a good noise reduction effect for transmission occasions (such as belt drive). 3. Increase the overall wall thickness of the dishwasher to reduce the noise generated by resonance, but the increase in thickness will lead to an increase in overall cost.

[0023] Embodiment 1

[0024] This embodiment provides a built-in dishwasher, such as Figure 1 , Figure 3 As shown, the built-in dishwasher includes a dishwasher body 11, which has a cavity inside, a door body 12 is arranged on the body 11, and the door body 12 has a door cavity 120. The built-in dishwasher also includes a noise reduction device 13 and a control module, which are fixed to the door body 12 and can block the gap between the door body and the inner wall of the cabinet to reduce the noise leakage of the whole machine. Figure 2 , which is a schematic structural diagram of the dishwasher 1 when assembled in the cabinet 2 .

[0025] Specifically, if Figure 3 , Figure 6 As shown, the noise reduction device 13 is fixedly arranged in the door cavity 120, and at least one side of the door body 12 is provided with a door cavity opening 124 connecting the inside and outside of the door cavity 120. The noise reduction device 13 includes a driving mechanism 131 and a sealing portion 132, wherein the driving mechanism 131 is fixedly arranged in the door cavity 120, and the sealing portion 132 is arranged corresponding to the driving mechanism 131, and the driving mechanism 131 is controlled to drive the sealing portion 132 to move to a specified position through the door cavity opening.

[0026] The control module controls the driving mechanism 131 to operate according to the working state of the built-in dishwasher.

[0027] In some embodiments, such as Figure 5 As shown, the door body 12 includes a door lining 121, a door lining frame 122 and a door plate 123. The door lining frame 122 is arranged around the door lining 121. A door cavity opening communicating with the door cavity 120 is opened at a position corresponding to the sealing portion 132 of the door lining frame 122. The sealing portion 132 can extend through the door cavity opening to the outside of the door cavity 120 or retract into the door cavity 120. When the sealing portion 132 extends to the outside of the door cavity 120, the gap between the door body 12 of the dishwasher and the inner wall of the cabinet can be completely or partially blocked, which reduces the noise leakage of the whole machine, thereby improving the noise performance of the whole machine.

[0028] The door panel 123 is fixed to the door lining frame 122 , and the door panel 123 , the door lining panel 121 and the door lining frame 122 form a door cavity 120 .

[0029] The driving mechanism 131 may be fixed to the door lining 121 or the door plate 123 in the door cavity 120. The sealing portion 132 is fixed to the power output shaft of the driving mechanism 131.

[0030] The sealing portion 132 can be horizontally arranged in the horizontal gap between the door body 12 and the inner wall of the cabinet, or can be vertically arranged in the vertical gap between the door body 12 and the inner wall of the cabinet. In this embodiment, the sealing portion 132 is arranged vertically as an example, and the power output shaft of the corresponding driving mechanism 131 is arranged horizontally, which can drive the sealing portion 132 to expand and contract horizontally.

[0031] The sealing portion 132 may include only a sealing strip arranged on one side, and a fixed sealing portion or no sealing portion may be arranged on the other side opposite thereto. When the dishwasher is assembled in a cabinet, the side with the fixed sealing portion or no sealing portion is tightly fitted with the inner wall of the cabinet to seal the gap on that side, and the driving mechanism 131 drives the movable sealing portion 132 to seal the gap on that side.

[0032] The sealing part 132 can also be provided with movable sealing strips on both sides, and the driving mechanism 131 can drive the sealing parts 132 on both sides to seal the gap on their sides. The driving mechanism 131 can be provided in a one-to-one correspondence with the sealing parts 132, and the sealing parts 132 on both sides can also be synchronously moved by one driving mechanism 131 at the same time. Specifically, a gear and two racks meshing with the gears can be used to realize that when the gear rotates in a certain direction, the two racks move synchronously and in opposite directions. There are many possible solutions, which will not be described in detail here.

[0033] like Figure 4 As shown, it is a schematic diagram of the structure of the sealing portion 132 being retracted. Figure 5 , which is a schematic structural diagram of the sealing portion 132 extending to the outside of the door cavity 120 .

[0034] An embedded dishwasher generally has three spray arms, including an upper spray arm, a middle spray arm and a lower spray arm, which are used to spray wash tableware of different heights. The sealing portion 132 includes sealing strips respectively arranged on both sides of the door body 12. In some embodiments, there are three noise reduction devices, namely an upper noise reduction device, a middle noise reduction device and a lower noise reduction device. The three noise reduction devices are arranged corresponding to the three spray arms, and the three noise reduction devices are arranged in sequence from top to bottom. In addition, the sealing strips on both sides of the three noise reduction devices are connected end to end from top to bottom, and the control module can control the driving mechanism of each noise reduction device to act independently.

[0035] like Figure 7As shown, the upper noise reduction device includes an upper driving mechanism 1311 and an upper sealing part 1321, the middle noise reduction device includes a middle driving mechanism 1312 and a middle sealing part 1322, and the noise reduction device includes a lower driving mechanism 1313 and a lower sealing part 1323, wherein the heights of the upper sealing part 1321, the middle sealing part 1322 and the lower sealing part 1323 are respectively equivalent to the heights of the upper spray arm, the middle spray arm and the lower spray arm.

[0036] In some embodiments, such as Figure 6 As shown, the built-in dishwasher further includes a door closing detection module 14, which is arranged on the door body 12 and is used to detect the switch state of the door body 12 and send the detection result to the control module, and the control module further includes controlling the action of the driving mechanism 131 according to the switch state of the door body 12. For example, only when the door body 12 is closed, it is possible to control the driving sealing part 132 to extend outward to achieve the effect of blocking the gap, otherwise the sealing part 132 is controlled to retract.

[0037] In this embodiment, the door closing detection module 14 includes a transmitting module and a receiving module, which are fixed on the left and right sides of the door lining frame 12 and are located above the sealing portion 132 .

[0038] The transmitting module transmits a light signal or a radar signal. When the door body is closed, the receiving module can receive the signal reflected from the cabinet. After receiving the signal and running the program, the receiving module feeds back to the control module. The control module starts the driving mechanism 131. The driving mechanism 131 drives the sealing part 132 on the telescopic shaft to move left and right, thereby completing the purpose of sealing the left and right sides of the door body 12.

[0039] The sealing part 132 can be realized by a soft-hard integrated foam strip, and the outer side of the sealing part 132 that contacts the inner wall of the cabinet is made of rubber material to achieve the purpose of sealing and wear resistance. The inner side of the sealing part 132 can be made of a foam material, which has a certain elasticity and will deform to a certain extent when squeezed. When the squeezing force disappears, it can return to its original state. The foam material part can play a role in buffering vibrations, preventing the vibrations generated when the dishwasher is working from being transmitted to the cabinet.

[0040] In some embodiments, such as Figure 4 As shown, the built-in dishwasher also includes an infrared detection module 15, which is arranged on the outside of the door body 12. Specifically, the infrared detection module 15 is arranged on the outer side of the door panel 123, and is used to detect the approach state of the human body and send the detected approach state of the human body to the control module. The control module also includes controlling the action of the driving mechanism according to the approach state of the human body.

[0041] When the door body 12 is closed, after a human hand touches the area of ​​the infrared detection module 15 , the control module controls the sealing portion 132 on the telescopic shaft to move toward the door cavity 120 , so that the user can easily open the door body 12 .

[0042] Since the sizes of household cabinets are different, when the dishwasher is installed in the cabinet, the distances between its two sides and the inner walls of different cabinets are also different. If the extension distance of the drive mechanism 131 is controlled to be fixed, it is easy to fail to achieve complete sealing, or the set distance is greater than the gap distance, resulting in damage to the drive mechanism 131.

[0043] In some embodiments, the built-in dishwasher also includes a distance detection module (not shown in the figure), which is used to detect the distance between the sealing portion 132 and the inner wall of the cabinet, and send it to the control module. The control module also includes controlling the action of the driving mechanism according to the distance between the sealing portion 132 and the inner wall of the cabinet, so as to avoid the situation where it cannot be completely closed when it is required, and to avoid the problem of damaging the driving mechanism 131 due to the setting of too large a distance.

[0044] Embodiment 2

[0045] This embodiment proposes a control method for an embedded dishwasher. The embedded dishwasher in the method is shown in the figure, including a dishwasher body 11, which has a cavity inside. A door body 12 is provided on the body 11, and the door body 12 has a door cavity 120. The embedded dishwasher also includes a noise reduction device 13 and a control module, which are fixed to the door body 12 and can seal the gap between the door body and the inner wall of the cabinet 2 to reduce noise leakage of the whole machine.

[0046] Specifically, as shown in the figure, the noise reduction device 12 is fixedly arranged in the door cavity 120, and at least one side of the door body 12 is provided with a door cavity opening connecting the inside and outside of the door cavity 120. The noise reduction device 13 includes a driving mechanism 131 and a sealing part 132, wherein the driving mechanism 131 is fixedly arranged in the door cavity 120, and the sealing part 132 is arranged corresponding to the driving mechanism 131, and the driving mechanism 131 is controlled to drive the sealing part 132 to move to a specified position through the door cavity opening.

[0047] The built-in dishwasher control method includes: The power-on status of the dishwasher is detected. When the dishwasher is turned on and running, the driving mechanism is controlled to drive the sealing part to extend out of the door cavity through the door cavity opening; otherwise, the sealing part is driven to retract into the door cavity.

[0048] The control method of the embedded dishwasher of the present invention controls the sealing part to move to a specified position according to the working state of the embedded dishwasher, and can seal the gap between the door body and the inner wall of the cabinet 2 to reduce the noise leakage of the whole machine, thereby improving the noise performance of the whole machine.

[0049] When a dishwasher is working, it corresponds to multiple operating stages, including drainage stage, water intake stage, washing stage, etc. The noise sources corresponding to different stages are completely different. Therefore, this embodiment also proposes a noise reduction method based on the characteristics of each stage to achieve the best noise reduction effect.

[0050] In some embodiments, when the driving mechanism 131 is controlled to drive the sealing portion 132 to move to a specified position through the door cavity, the specified position includes a fully enclosed position and a semi-enclosed position, the fully enclosed position includes a first position where the sealing portion 132 contacts the inner wall of the cabinet 2 and the sealing portion 132 is not compressed, and a second position where the sealing portion 132 contacts the inner wall of the cabinet 2 and the sealing portion 132 is compressed, and the semi-enclosed position refers to a flash gap between the sealing portion 132 and the inner wall of the cabinet 2. The embedded dishwasher control method also includes: When the dishwasher is turned on and operated, the current operation stage of the dishwasher is detected, and the distance that the driving mechanism 131 extends outward is controlled according to the operation stage, so that the sealing part 132 moves to a specified position.

[0051] The operation stage includes a drainage stage, a water intake stage and a washing stage. The designated position corresponding to the drainage stage is the semi-closed position, the designated position corresponding to the water intake stage is the first position, and the designated position corresponding to the washing stage is the second position.

[0052] The noise source in the drainage stage comes from the drainage pump. When the drainage pump is in operation, the speed is as high as 3000rpm, which can excite the resonance of the cabinet 2 in contact with the dishwasher. When the detection module detects that the program runs to the drainage stage, the detection module will automatically feed back the detected signal to the control module. After receiving the signal, the control module generates a control signal to control the driving mechanism 131. The sealing part 132 is driven by the driving mechanism 131 to move to a semi-closed position. For example, the sealing part 132 is 27mm away from the cabinet, so that the sealing part 132 is separated from the cabinet 2, thereby avoiding resonance between the dishwasher and the cabinet 2 and solving the noise problem caused by resonance.

[0053] The noise source in the water inlet stage comes from the high-pressure water flow in the water pipe. The high-pressure water flow cannot arouse the vibration of the dishwasher and the cabinet 2. It is mainly low-frequency noise generated by water bubbles, etc., which mainly relies on air and solid media for transmission. Therefore, when the detection module detects that the program runs to the water inlet stage, the detection module will automatically feed back the detected signal to the control module. After receiving the signal, the control module generates a control signal to control the drive mechanism 131, and the sealing part 132 is driven by the drive mechanism 131 to move to the first position of the closed position, for example, the sealing part 132 is 0mm away from the cabinet, so as to achieve the purpose of sealing the sealing part 132 and the cabinet 2, that is, to prevent the noise from propagating through the gap through the air, and at the same time block the noise from continuing to propagate through the cabinet 2, so as to achieve the effect of noise reduction.

[0054] The noise in the washing stage comes from the spray water from the washing pump and the spray arm, which can easily arouse resonance between the dishwasher and the cabinet 2. When the detection module detects that the program is running to the washing stage, the detection module will automatically feed back the detected signal to the control module. After receiving the signal, the control module controls the sealing part 132 to contact the inner wall of the cabinet 2 and the sealing part 132 is compressed to the second position. For example, the sealing part 132 can be compressed to 2-3mm. Experiments have shown that when the sealing part 132 is in a compressed state, the dishwasher and the cabinet 2 will not resonate, and the purpose of sealing the sealing part 132 and the cabinet 2 is achieved, thereby improving the overall noise performance of the dishwasher.

[0055] The determination of each designated position can be achieved by using a distance detection module (not shown in the figure). The distance detection module is used to detect the distance between the sealing part 132 and the inner wall of the cabinet 2, and send it to the control module. The control module also includes controlling the action of the driving mechanism according to the distance between the sealing part 132 and the inner wall of the cabinet 2, so that the sealing part 132 can move to the designated position as required. At the same time, it can also avoid the situation where it cannot be completely closed when it is required, and avoid the problem of damaging the driving mechanism 131 due to the setting of too large a distance.

[0056] In some embodiments, the built-in dishwasher includes an upper spray arm, a middle spray arm and a lower spray arm. In some embodiments, there are three noise reduction devices, namely an upper noise reduction device, a middle noise reduction device and a lower noise reduction device. The three noise reduction devices are arranged corresponding to the three spray arms, and the three noise reduction devices are arranged in sequence from top to bottom. In addition, the sealing strips on both sides of the three noise reduction devices are connected end to end from top to bottom, and the control module can control the driving mechanism of each noise reduction device to operate independently.

[0057] like Figure 7 As shown, the upper noise reduction device includes an upper driving mechanism 1311 and an upper sealing part 1321, the middle noise reduction device includes a middle driving mechanism 1312 and a middle sealing part 1322, and the noise reduction device includes a lower driving mechanism 1313 and a lower sealing part 1323, wherein the heights of the upper sealing part 1321, the middle sealing part 1322 and the lower sealing part 1323 are respectively equivalent to the heights of the upper spray arm, the middle spray arm and the lower spray arm.

[0058] The built-in dishwasher control method also includes: When the dishwasher is turned on and running, and the running stage is the washing stage, it also includes controlling the corresponding noise reduction device action according to the current water spraying state of each spray arm, including: controlling the noise reduction device corresponding to the spray arm that is spraying water to move to the first position.

[0059] When the detection module detects the movement of the spray arm under different states, the corresponding sealing part 132 extends outward under the action of the control system, thereby reducing the noise leakage caused by the water flow hitting the inner tank of the dishwasher. At the same time, the contact area between the sealing part 132 and the cabinet 2 can be weakened, avoiding resonance between the dishwasher and the cabinet 2, and ultimately improving the noise performance of the whole machine.

[0060] In some embodiments, before the step of detecting the power-on status of the dishwasher, a step of detecting whether the door body is closed is also included. When the door body is closed, the step of detecting the power-on status of the dishwasher is executed.

[0061] In some embodiments, the built-in dishwasher further includes a door closing detection module 14, which is disposed on the door body 12 and is used to detect the switch state of the door body 12 and send the detection result to the control module, and the control module further includes controlling the action of the driving mechanism 131 according to the switch state of the door body 12. For example, only when the door body 12 is closed, it is possible to control the driving sealing portion 132 to extend outward to achieve the effect of blocking the gap, otherwise the sealing portion 132 is controlled to retract.

[0062] In this embodiment, the door closing detection module 14 includes a transmitting module and a receiving module, which are fixed on the left and right sides of the door lining frame 12 and are located above the sealing portion 132 .

[0063] The transmitting module transmits a light signal or a radar signal. When the door body is closed, the receiving module can receive the signal reflected back from the cabinet 2. After receiving the signal and running the program, the receiving module feeds back to the control module. The control module starts the driving mechanism 131. The driving mechanism 131 drives the sealing part 132 on the telescopic shaft to move left and right, thereby completing the purpose of sealing the left and right sides of the door body 12.

[0064] The sealing part 132 can be realized by a soft-hard integrated foam strip, and the outer side of the sealing part 132 that contacts the inner wall of the cabinet 2 is made of rubber material to achieve the purpose of sealing and wear resistance. The inner side of the sealing part 132 can be made of a foam material, which has a certain elasticity and undergoes a certain deformation when squeezed. When the squeezing force disappears, it can return to its original state. The foam material part can play a role in buffering vibrations, preventing the vibrations generated when the dishwasher is working from being transmitted to the cabinet 2.

[0065] In some embodiments, the built-in dishwasher also includes an infrared detection module 15, which is arranged on the outside of the door body 12. Specifically, the infrared detection module 15 is arranged on the outer side of the door panel 123, and is used to detect the approach state of the human body and send the detected approach state of the human body to the control module. The control module also includes controlling the action of the driving mechanism according to the approach state of the human body.

[0066] When the door body 12 is closed, after a human hand touches the area of ​​the infrared detection module 15 , the control module controls the sealing portion 132 on the telescopic shaft to move toward the door cavity 120 , so that the user can easily open the door body 12 .

[0067] Since the sizes of different household cabinets 2 are different, when the dishwasher is installed in the cabinet 2, the distances between its two sides and the inner walls of different cabinets 2 are also different. If the extension distance controlled by the drive mechanism 131 is fixed, it is easy to fail to achieve complete sealing, or the set distance is greater than the gap distance, resulting in damage to the drive mechanism 131.

[0068] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
