Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and more particularly, to a cooking appliance. Background Art

[0002] Currently, during the use of cooking appliances in the related art, it is usually necessary to take out the water box from the cooking appliance, manually add water to the water box, and then put the water box back into the cooking appliance. The operation is cumbersome, and it is not convenient to control the water volume, which affects the cooking effect of the cooking appliance. Summary of the Invention

[0003] An embodiment of the present invention aims to at least solve one of the technical problems existing in the prior art.

[0004] To this end, a first aspect of an embodiment of the present invention provides a cooking appliance.

[0005] In view of this, according to a first aspect of an embodiment of the present invention, there is provided a cooking appliance, which includes: an appliance body; a water storage box provided on the appliance body; a water pipe line, one end of the water pipe line is connected to the water storage box, and the other end of the water pipe line is connected to a water source; a switch assembly provided on the water pipe line for controlling the on or off of the water pipe line; a water level detection assembly provided in the water storage box, the water level detection assembly can detect multiple water levels in the water storage box, and the multiple water levels at least include a first water level and a second water level, and the second water level is higher than the first water level; wherein, based on the water in the water storage box being lower than the first water level, the switch assembly is opened to make the water pipe line conductive, and based on the water in the water storage box reaching the second water level, the switch assembly is closed to make the water pipe line cut off.

[0006] The cooking appliance provided by the embodiment of the present invention includes an appliance body, a water storage box, a water pipe line, a switch assembly, and a water level detection assembly. Specifically, the water storage box is arranged on the appliance body. It can be understood that the appliance body is provided with a cooking cavity, the cooking appliance includes a steam generator, and the steam generator is respectively connected to the cooking cavity and the water storage box. Specifically, during the use of the cooking appliance, the water in the water storage box flows into the steam generator, is heated by a heating element inside the steam generator to form steam, and the steam enters the cooking cavity to perform steam cooking, that is, steaming, on the food in the cooking cavity. Optionally, the cooking appliance includes a steamer, a steam oven, or a microwave steam oven.

[0007] It can be understood that to ensure the effective progress of the cooking process of the cooking appliance, it is necessary to ensure that there is sufficient water in the water storage box. The water level detection component can detect the water level in the water storage box. Specifically, when the water in the water storage box is lower than the first water level, it indicates that the amount of water in the current water storage box is insufficient and water needs to be added. At this time, the switch component is opened to conduct the water pipe path, and the external water source flows into the water storage box after passing through the water pipe path and the switch component to increase the amount of water in the water storage box. That is, the first water level is the water shortage level. When the water in the water storage box is replenished to the second water level, it indicates that the replenishment of the water in the water storage box is completed. At this time, the switch component is closed to cut off the water pipe path. That is, the second water level is the water replenishment in-place level, thereby realizing automatic water replenishment into the water storage box, preventing the cooking appliance from cooking when the water storage box is short of water, ensuring the cooking performance of the cooking appliance. At the same time, compared with manual water addition in the related art, while accurately controlling the water supply volume in the water storage box, the cooking process is simplified and the cooking effect is ensured.

[0008] Since the water level detection component can detect multiple water levels of the water in the water storage box, that is to say, the water level detection component is a high-precision water level detection component, which can realize the accurate detection of multiple water levels in the water storage box, so as to ensure the cooking performance of the cooking appliance while realizing the automatic water supply of the cooking appliance and ensuring that the water storage box will not overflow or be short of water.

[0009] Optionally, the other end of the water pipe path is connected to the faucet in the user's home.

[0010] In some technical solutions, optionally, the multiple water levels further include a third water level, and the third water level is higher than the second water level.

[0011] In this technical solution, since the first water level and the second water level are respectively lower than the third water level, that is, the third water level is the full overflow level. During the use of the cooking appliance, when the switch component has a functional abnormality and the water in the water storage box reaches the second water level, it is not closed in time, resulting in continuous water supply in the water storage box. When the water level detection component detects that the water in the water storage box reaches the third water level, the cooking appliance can emit an alarm signal to remind the user that the switch component has a functional abnormality and the water storage box is about to overflow, and the user can manually close the water source, thereby ensuring that the amount of water in the water storage box is sufficient during the cooking process of the cooking appliance and will not overflow, improving the reliability of the cooking appliance and being beneficial to extending the service life of the cooking appliance.

[0012] In some technical solutions, optionally, the water level detection component includes multiple detection parts, and the multiple detection parts can respectively detect multiple water levels in the water storage box; the multiple detection parts at least include a first detection part and a second detection part, the first detection part and the second detection part are arranged at intervals along the height direction of the appliance body, the first detection part is used to detect the first water level, and the second detection part is used to detect the second water level.

[0013] In this technical solution, it is defined that the water level detection component includes a plurality of detection parts. Specifically, the plurality of detection parts can respectively detect a plurality of water levels. The plurality of detection parts at least include a first detection part and a second detection part arranged along the height direction. The first detection part is used to detect the first water level, and the second detection part is used to detect the second water level.

[0014] Specifically, when the first detection part detects that the water in the water storage box is lower than the first water level, it indicates that the amount of water in the current water storage box is insufficient and water needs to be added. At this time, the switch component is opened to conduct the water pipe path. After the external water source passes through the water pipe path and the switch component, it flows into the water storage box to increase the amount of water in the water storage box. When the second detection part detects that the water in the water storage box is replenished to the second water level, it indicates that the replenishment of the water in the water storage box is completed. At this time, the switch component is closed to cut off the water pipe path, thereby realizing automatic water replenishment into the water storage box.

[0015] Optionally, the plurality of detection parts further include a third detection part for detecting a third water level. Specifically, when the third detection part detects that the water in the water storage box reaches the third water level, it indicates that the switch component has a functional abnormality and fails to close in time when the water in the water storage box reaches the second water level, resulting in continuous water supply in the water storage box. At this time, the cooking appliance can emit an alarm signal to remind the user that the switch component has a functional abnormality and the water storage box is about to overflow, and the user can manually turn off the water source.

[0016] In some technical solutions, optionally, the water storage box includes a frame and a box body. Among them, the frame is provided with a receiving cavity, the water level detection component is arranged on the frame, and the box body is removably arranged in the receiving cavity and communicated with the water pipe path; the water level detection component further includes a detection piece for detecting whether the box body is contained in the receiving cavity.

[0017] In this technical solution, it is defined that the water storage box includes a frame and a box body. Specifically, the frame is provided with a receiving cavity, and the box body is removably arranged in the receiving cavity, so that manual water addition or automatic water supply can be selected according to the user's needs, enriching the use functions of the cooking appliance and being beneficial to improving the user experience. In addition, since the box body can be taken out, after the cooking appliance is used for a long time, the box body can be taken out for cleaning to avoid affecting the user's physical health due to bacteria breeding in the box body.

[0018] The water level detection component further includes a detection piece, and the detection piece can detect whether the box body is contained in the receiving cavity. Specifically, before opening the switch component to conduct the water pipe path for automatic water supply, it is detected by the detection piece whether the box body has been put into the receiving cavity after being cleaned. When the detection piece detects that the box body is contained in the receiving cavity, the switch component is then opened for automatic water supply, which is beneficial to ensuring the cooking performance of the cooking appliance.

[0019] In some technical solutions, optionally, the water level detection component is arranged on the side of the frame facing away from the accommodation cavity; the frame is provided with a through hole, and the through hole communicates with the accommodation cavity, and the water level detection component detects multiple water levels in the cartridge body through the through hole.

[0020] In this technical solution, since the water level detection component is arranged on the side of the frame facing away from the accommodation cavity, that is to say, the water level detection component is arranged outside the frame, so that while realizing the detection of multiple water levels in the cartridge body, it is possible to avoid occupying the space of the accommodation cavity due to the arrangement of the water level detection component inside the frame, and the volume of the cartridge body can be ensured to the greatest extent.

[0021] The frame is provided with a through hole, and the through hole communicates with the accommodation cavity. The water level detection component detects multiple water levels in the cartridge body through the through hole, so as to realize the accurate detection of multiple water levels in the water storage box. While realizing the automatic water supply of the cooking appliance, it is ensured that the water storage box will not overflow or be short of water, and the cooking performance of the cooking appliance is ensured.

[0022] Optionally, the number of through holes is multiple, and the multiple through holes correspond to the multiple detection parts one by one.

[0023] In some technical solutions, optionally, the side of the cartridge body facing the water level detection component is configured as a light-transmitting member.

[0024] In this technical solution, since the side of the cartridge body facing the water level detection component is a light-transmitting member, the water level detection component can accurately detect multiple water levels in the cartridge body.

[0025] Optionally, the whole cartridge body is a light-transmitting member.

[0026] In some technical solutions, optionally, the water level detection component includes a bracket, a cover body and a water level detection board. Among them, the bracket is arranged on the water storage box, the cover body is connected to the bracket, and the water level detection board is arranged between the cover body and the bracket for detecting multiple water levels in the water storage box.

[0027] In this technical solution, it is defined that the water level detection component includes a bracket, a cover body and a water level detection board. Specifically, the bracket is arranged on the water storage box, the cover body is connected to the bracket, and the water level detection board is located between the cover body and the bracket. That is to say, the water level detection board is clamped between the cover body and the bracket, so as to realize the reliable installation of the water level detection board.

[0028] It can be understood that the water level detection board can detect at least three water levels of the water in the water storage box. That is to say, the water level detection board is a high-precision water level detection board, which can realize the accurate detection of multiple water levels in the water storage box. While realizing the automatic water supply of the cooking appliance, it is ensured that the water storage box will not overflow or be short of water, and the cooking performance of the cooking appliance is ensured.

[0029] Optionally, one of the cover body and the bracket is provided with a snap buckle, and the other is provided with a buckle position, and the snap buckle and the buckle position are cooperatively connected.

[0030] In some technical solutions, optionally, the switch assembly includes a housing and a switch valve. Among them, the housing is provided with a communication channel, the communication channel is communicated with the water pipe, the switch valve is arranged in the communication channel, and the switch valve can move between a first position and a second position. Based on the switch valve being in the first position, the switch valve and the housing form a throttling channel, and the throttling channel is communicated with the communication channel. Based on the switch valve being in the second position, the switch valve abuts against the housing, and the communication channel is cut off.

[0031] In this technical solution, it is defined that the switch assembly includes a housing and a switch valve. Specifically, the housing is provided with a communication channel, and the switch valve is movably arranged in the communication channel.

[0032] Specifically, when the water level detection component detects that the water in the water storage box is lower than the first water level, it means that the current amount of water in the water storage box is insufficient and water needs to be added. At this time, the switch valve moves to the first position and forms a throttling channel with the housing. The external water source flows into the water storage box through the water pipe, the communication channel and the throttling channel to increase the amount of water in the water storage box. When the water level detection component detects that the water in the water storage box has been replenished to the second water level, it means that the replenishment of the water in the water storage box is completed. At this time, the switch valve moves to the second position and abuts against the housing, the throttling channel is closed, and the communication channel is cut off, and the water supply is stopped, so as to realize automatic replenishment of water into the water storage box, prevent the cooking appliance from cooking when the water storage box is short of water, and ensure the cooking performance of the cooking appliance.

[0033] Since when the communication channel is conducted, the communication channel is communicated with the throttling channel, that is to say, during the process of water flowing to the water storage box, throttling will be carried out through the throttling channel, so that the flow rate and velocity of water can be controlled, ensuring that the water supply process is stable and uniform, avoiding large water level fluctuations in the water storage box due to large water pressure and rapid water flow, and further avoiding false alarms of the water level detection component, which is beneficial to further ensuring the cooking performance of the cooking appliance and improving the reliability of the cooking appliance.

[0034] In some technical solutions, optionally, the switch valve includes a valve body and a throttling member. Among them, based on the valve body being in the first position, the throttling member and the housing form a throttling channel. Based on the valve body being in the second position, the valve body pushes the throttling member to move so that the throttling member abuts against the housing.

[0035] In this technical solution, the switch valve is defined as including a valve body and a throttling member. Specifically, when the water level detection component detects that the water in the water storage box is lower than the first water level, it indicates that the current amount of water in the water storage box is insufficient and water needs to be added. At this time, the valve body moves to the first position, and the throttling member and the shell form a throttling channel. The external water source flows into the water storage box through the water pipe, the connecting channel and the throttling channel to increase the amount of water in the water storage box.

[0036] When the water level detection assembly detects that the water in the water storage box has reached the second level, indicating that the water storage box has been fully replenished, the valve body moves to the second position, pushing the throttling member against the housing. The throttling channel is closed, the communication channel is blocked, and the water supply is stopped. This automatically replenishes the water storage box, preventing the cooking appliance from cooking when the water storage box is low on water, thereby ensuring the cooking performance of the cooking appliance.

[0037] In some technical solutions, optionally, the throttling member includes an elastic member.

[0038] In this technical solution, since the throttling member is an elastic member, when the switch assembly is opened, that is, the connecting channel is connected, the elastic member can adapt to different water pressures and produce different deformations, and the resulting deformation causes the cross-sectional area of the throttling channel to change, thereby ensuring that the throttling channel always maintains a specific flow rate, that is, the switch assembly is a constant current switch, which is conducive to ensuring a stable and uniform water supply process, avoiding large water level fluctuations in the water storage box due to high water pressure and rapid water flow, and then causing false alarms of the water level detection assembly, which is conducive to further ensuring the cooking performance of the cooking appliance and improving the reliability of the cooking appliance.

[0039] Optionally, the elastic member includes a silicone pad.

[0040] In some technical solutions, optionally, the housing is further provided with a guide channel; the throttling member includes a body and a guide portion, wherein the guide portion is provided on a side of the body away from the valve body and is at least partially located in the guide channel.

[0041] This technical solution defines a throttling member comprising a body and a guide portion. Specifically, the guide portion is disposed on a side of the body facing away from the valve body, with at least a portion of the guide portion located within a guide channel. Movement of the valve body can push the body to form a throttling channel with the housing, or to close the throttling channel. During this process, the guide portion located within the guide channel guides and limits the body. When the water in the water storage box reaches a second water level, this prevents the throttling channel formed between the body and the housing from being effectively closed due to misalignment of the body, thereby preventing the risk of overflow from the water storage box due to continued water supply, further improving the reliability of the cooking appliance.

[0042] Optionally, the main body and the throttling element are an integrated structure.

[0043] In some technical solutions, optionally, the communication channel includes a first communication port and a second communication port, and the water pipe includes a first pipe and a second pipe. Among them, both ends of the first pipe are respectively connected to the first communication port and the water source, and both ends of the second pipe are respectively connected to the second communication port and the water storage box; among them, the first pipe is a pressure-resistant pipe.

[0044] In this technical solution, it is defined that the water pipe includes a first pipe and a second pipe. Specifically, one end of the first pipe is connected to the first communication port, the other end of the first pipe is connected to the water source, one end of the second pipe is connected to the second communication port, and the other end of the second pipe is connected to the water storage box.

[0045] Specifically, when the water level detection component detects that the water in the water storage box is lower than the first water level, the switch valve moves to the first position, and the water flows through the first pipe, the communication channel, the throttling channel and the second pipe into the water storage box respectively, so as to increase the water volume in the water storage box and realize the automatic water supply of the cooking appliance.

[0046] Since the first pipe is a pressure-resistant pipe, that is to say, the first pipe has a certain pressure-resistant performance, so it can resist the water pressure to a certain extent, prevent the first pipe from deforming, and is beneficial to extending the service life of the first pipe.

[0047] Optionally, the first pipe includes a PE (Polyethylene) pipe. Compared with the silicone hose used in the related technology, the PE pipe has good pressure-resistant performance, prevents deformation, and is beneficial to extending the service life of the first pipe.

[0048] In some technical solutions, optionally, the cooking appliance further includes a pipe joint, which is arranged on the appliance body and exposed outside the appliance body, and the other end of the water pipe is connected to the water source through the pipe joint.

[0049] In this technical solution, it is defined that the cooking appliance further includes a pipe joint. Specifically, the water pipe is connected to the water source through the pipe joint. Optionally, the pipe joint can be connected to the faucet or water tank of the user's home to realize the supply of the water source.

[0050] In some technical solutions, optionally, the cooking appliance further includes a controller, and either the water level detection component or the switch component is electrically connected to the controller.

[0051] In this technical solution, it is defined that the cooking appliance further includes a controller. Specifically, the water level detection component and the switch component are respectively electrically connected to the controller.

[0052] Specifically, when the water level detection assembly detects that the water level in the water storage box is below a first water level, it transmits a signal to the controller, which issues a command to control the switch assembly to open, thereby connecting the water pipeline. External water flows into the water storage box through the water pipeline and the switch assembly, thereby increasing the water volume in the water storage box. When the water level detection assembly detects that the water in the water storage box has been replenished to a second water level, indicating that the water volume in the water storage box has been replenished, the water level detection assembly transmits a signal to the controller, which issues a command to control the switch assembly to close, thereby cutting off the water pipeline. This automatically replenishes the water storage box, preventing the cooking appliance from cooking when the water storage box is low on water, thereby ensuring the cooking performance of the cooking appliance.

[0053] When the water level detection component detects that the water in the water storage box reaches the third water level, it indicates that the switch component has a malfunction. When the water in the water storage box reaches the second water level, it is not closed in time, resulting in continuous water supply in the water storage box. The water level detection component transmits the overflow signal to the controller. The controller controls the voice module of the cooking appliance to issue a voice alarm, or controls the display module to display an alarm message, reminding the user that the switch component is malfunctioning and the water storage box is about to overflow. The water source can be manually turned off to ensure that the cooking appliance has sufficient water in the water storage box during cooking and will not overflow, which is beneficial to improving the user experience.

[0054] Optionally, the controller includes a main control board or a microprocessor.

[0055] In some technical solutions, optionally, the appliance body is provided with a cooking cavity, and the cooking appliance further comprises a steam generator, which is respectively connected to the cooking cavity and the water storage box.

[0056] This technical solution specifies that the cooking appliance also includes a steam generator. Specifically, the steam generator is connected to the cooking cavity and the water storage tank. Specifically, during use of the cooking appliance, water in the water storage tank flows into the steam generator, where it is heated by a heating element within the steam generator to form steam. The steam then enters the cooking cavity to steam-cook, or steam, the food in the cooking cavity.

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0071] In the following description, numerous specific details are set forth to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited by the specific embodiments disclosed below.

[0072] Reference will now be made to Figures 1 to 9 describe a cooking appliance 100 provided according to some embodiments of the present invention.

[0073] In an embodiment according to the present application, as Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 9 shown, a cooking appliance 100 is proposed. The cooking appliance 100 includes: an appliance body 110; a water storage box 120 provided on the appliance body 110; a water pipe line 130, one end of the water pipe line 130 is connected to the water storage box 120, and the other end of the water pipe line 130 is connected to a water source; a switch assembly 140 provided on the water pipe line 130 for controlling the on or off of the water pipe line 130; a water level detection assembly 150 provided in the water storage box 120, the water level detection assembly 150 can detect multiple water levels 160 in the water storage box 120, and the multiple water levels 160 at least include a first water level 161 and a second water level 162, and the second water level 162 is higher than the first water level 161; wherein, based on the water in the water storage box 120 being lower than the first water level 161, the switch assembly 140 is opened to make the water pipe line 130 conductive, and based on the water in the water storage box 120 reaching the second water level 162, the switch assembly 140 is closed to make the water pipe line 130 cut off.

[0074] The cooking appliance 100 provided by the embodiments of the present invention includes an appliance body 110, a water storage box 120, a water pipe line 130, a switch assembly 140, and a water level detection assembly 150. Specifically, the water storage box 120 is provided on the appliance body 110. It can be understood that the appliance body 110 is provided with a cooking cavity, and the cooking appliance 100 includes a steam generator 210, and the steam generator 210 is respectively connected to the cooking cavity and the water storage box 120. Specifically, during the use of the cooking appliance 100, the water in the water storage box 120 flows into the steam generator 210, is heated by a heating element inside the steam generator 210 to form steam, and the steam enters the cooking cavity to perform steam cooking, i.e., steaming, on the ingredients in the cooking cavity. Optionally, the cooking appliance 100 includes a steam oven, a steam convection oven, or a microwave steam convection oven.

[0075] It can be understood that to ensure the effective progress of the cooking process of the cooking appliance 100, it is necessary to ensure that there is sufficient water in the water storage box 120. The water level detection component 150 can detect the water level 160 of the water in the water storage box 120. Specifically, when the water in the water storage box 120 is lower than the first water level 161, it indicates that the amount of water in the current water storage box 120 is insufficient and water needs to be added. At this time, the switch component 140 is opened to conduct the water pipe path 130. After the external water source passes through the water pipe path 130 and the switch component 140, it flows into the water storage box 120 to increase the amount of water in the water storage box 120. That is, the first water level 161 is the water shortage level. When the water in the water storage box 120 is replenished to the second water level 162, it indicates that the replenishment of the water in the water storage box 120 is completed. At this time, the switch component 140 is closed to cut off the water pipe path 130. That is, the second water level 162 is the water replenishment in place level, so as to realize automatic water replenishment into the water storage box 120, prevent the cooking appliance 100 from cooking when the water storage box 120 is short of water, ensure the cooking performance of the cooking appliance 100, and at the same time, compared with manual water addition in the related art, while accurately controlling the water supply amount in the water storage box 120, simplify the cooking process and ensure the cooking effect.

[0076] Since the water level detection component 150 can detect at least three water levels 160 of the water in the water storage box 120, that is to say, the water level detection component 150 is a high-precision water level detection component 150, which can realize the accurate detection of multiple water levels 160 in the water storage box 120. Thus, while realizing automatic water supply of the cooking appliance 100, it is ensured that the water in the water storage box 120 will not overflow or be short of water, and the cooking performance of the cooking appliance 100 is ensured.

[0077] Optionally, the other end of the water pipe path 130 is connected to the faucet in the user's home.

[0078] As Figure 1 shown, in some embodiments, optionally, the multiple water levels 160 further include a third water level 163, and the third water level 163 is higher than the second water level 162.

[0079] In this embodiment, the first water level 161 and the second water level 162 are respectively lower than the third water level 163, that is, the third water level 163 is the overflow water level 160. During the use of the cooking appliance 100, when the switch assembly 140 malfunctions and the water in the water storage box 120 reaches the second water level 162, it is not closed in time, resulting in continuous water supply in the water storage box 120. When the water level detection assembly 150 detects that the water in the water storage box 120 reaches the third water level 163, the cooking appliance 100 can emit an alarm signal to remind the user that the switch assembly 140 malfunctions and the water storage box 120 is about to overflow, and the user can manually close the water source, so as to ensure that the water in the water storage box 120 is sufficient during the cooking process of the cooking appliance 100 without overflowing, improving the reliability of the cooking appliance 100 and being beneficial to extending the service life of the cooking appliance 100.

[0080] As Figure 1 and Figure 2 shown, in some embodiments, optionally, the water level detection assembly 150 includes a plurality of detection parts 151, and the plurality of detection parts 151 can respectively detect a plurality of water levels 160 in the water storage box 120; the plurality of detection parts 151 at least include a first detection part 152 and a second detection part 156, and the first detection part 152 and the second detection part 156 are arranged at intervals along the height direction of the appliance body 110, and the first detection part 152 is used to detect the first water level 161, and the second detection part 156 is used to detect the second water level 162.

[0081] In this embodiment, it is defined that the water level detection assembly 150 includes a plurality of detection parts 151. Specifically, the plurality of detection parts 151 can respectively detect a plurality of water levels 160. The plurality of detection parts 151 at least include a first detection part 152 and a second detection part 156 arranged along the height direction. The first detection part 152 is used to detect the first water level 161, and the second detection part 156 is used to detect the second water level 162.

[0082] Specifically, when the first detection part 152 detects that the water in the water storage box 120 is lower than the first water level 161, it means that the water volume in the current water storage box 120 is insufficient and water needs to be added. At this time, the switch assembly 140 is opened to conduct the water pipe path 130, and the external water source flows into the water storage box 120 after passing through the water pipe path 130 and the switch assembly 140 to increase the water volume in the water storage box 120. When the second detection part 156 detects that the water in the water storage box 120 is replenished to the second water level 162, it means that the water volume in the water storage box 120 has been replenished. At this time, the switch assembly 140 is closed to cut off the water pipe path 130, thereby realizing automatic water replenishment to the water storage box 120.

[0083] Optionally, the multiple detection units 151 also include a third detection unit 157, which is used to detect the third water level 163. Specifically, when the third detection unit 157 detects that the water in the water box 120 reaches the third water level 163, it indicates that the switch assembly 140 has a malfunction. When the water in the water box 120 reaches the second water level 162, it is not closed in time, resulting in continuous water supply in the water box 120. At this time, the cooking appliance 100 can send an alarm signal to remind the user that the switch assembly 140 is malfunctioning and the water box 120 is about to overflow, and the water source can be manually turned off.

[0084] like Figure 1 、 Figure 2 、 Figure 3 and Figure 8 As shown, in some embodiments, optionally, the water storage box 120 includes a frame 121 and a box body 123, wherein the frame 121 is provided with a accommodating cavity 122, the water level detection component 150 is provided on the frame 121, and the box body 123 is removably provided in the accommodating cavity 122 and is connected to the water pipeline 130; the water level detection component 150 also includes a detection component 158 for detecting whether the box body 123 is contained in the accommodating cavity 122.

[0085] In this embodiment, the water storage box 120 is defined as comprising a frame 121 and a box body 123. Specifically, the frame 121 is provided with a receiving cavity 122, and the box body 123 is removably disposed within the receiving cavity 122. This allows for manual or automatic water supply, depending on the user's needs, enriching the functionality of the cooking appliance 100 and enhancing the user experience. Furthermore, since the box body 123 is removable, it can be removed and cleaned after prolonged use of the cooking appliance 100, preventing bacterial growth within the box body 123 and potentially affecting the user's health.

[0086] The water level detection assembly 150 also includes a detection member 158, which can detect whether the cassette body 123 is contained within the accommodating cavity 122. Specifically, before the switch assembly 140 is turned on to connect the water conduit 130 for automatic water supply, the detection member 158 detects whether the cleaned cassette body 123 has been placed within the accommodating cavity 122. If the detection member 158 detects that the cassette body 123 is contained within the accommodating cavity 122, the switch assembly 140 is turned on again to automatically supply water, thereby ensuring the cooking performance of the cooking appliance 100.

[0087] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the water level detection component 150 is arranged on the side of the frame 121 away from the accommodating cavity 122; the frame 121 is provided with a through hole 124, the through hole 124 is connected to the accommodating cavity 122, and the water level detection component 150 detects multiple water levels 160 in the box body 123 through the through hole 124.

[0088] In this embodiment, since the water level detection component 150 is disposed on the side of the frame 121 facing away from the accommodation cavity 122, that is to say, the water level detection component 150 is disposed outside the frame 121, so that while multiple water levels 160 in the cartridge body 123 can be detected, it is possible to avoid occupying the space of the accommodation cavity 122 due to the water level detection component 150 being disposed within the frame 121, and the volume of the cartridge body 123 can be ensured to the greatest extent.

[0089] The frame 121 is provided with through holes 124 which communicate with the accommodation cavity 122. The water level detection component 150 detects multiple water levels 160 in the cartridge body 123 through the through holes 124, thereby realizing accurate detection of multiple water levels 160 in the water storage cartridge 120. While realizing automatic water supply of the cooking appliance 100, it is ensured that the water storage cartridge 120 will not overflow or be short of water, and the cooking performance of the cooking appliance 100 is ensured.

[0090] Optionally, the number of the through holes 124 is multiple, and the multiple through holes 124 correspond to the multiple detection parts 151 one by one.

[0091] In some embodiments, optionally, the side of the cartridge body 123 facing the water level detection component 150 is configured as a light-transmitting member.

[0092] In this embodiment, since the side of the cartridge body 123 facing the water level detection component 150 is a light-transmitting member, accurate detection of multiple water levels 160 in the cartridge body 123 by the water level detection component 150 can be realized.

[0093] Optionally, the entire cartridge body 123 is a light-transmitting member.

[0094] As Figure 2 shown, in some embodiments, optionally, the water level detection component 150 includes a bracket 153, a cover body 154, and a water level detection board 155. Among them, the bracket 153 is disposed on the water storage cartridge 120, the cover body 154 is connected to the bracket 153, and the water level detection board 155 is disposed between the cover body 154 and the bracket 153 for detecting multiple water levels 160 in the water storage cartridge 120.

[0095] In this embodiment, it is defined that the water level detection component 150 includes a bracket 153, a cover body 154, and a water level detection board 155. Specifically, the bracket 153 is disposed on the water storage cartridge 120, the cover body 154 is connected to the bracket 153, and the water level detection board 155 is located between the cover body 154 and the bracket 153. That is to say, the water level detection board 155 is clamped between the cover body 154 and the bracket 153, thereby realizing reliable installation of the water level detection board 155.

[0096] It is understandable that the water level detection board 155 can detect at least three water levels 160 of the water in the water storage box 120. That is to say, the water level detection board 155 is a high-precision water level detection board 155, which can realize the accurate detection of multiple water levels 160 in the water storage box 120. Thus, while realizing the automatic water supply of the cooking appliance 100, it is ensured that the water in the water storage box 120 will not overflow or be short of water, and the cooking performance of the cooking appliance 100 is ensured.

[0097] Optionally, one of the cover body 154 and the bracket 153 is provided with a buckle, and the other is provided with a buckle position, and the buckle and the buckle position are connected in cooperation.

[0098] Such as Figure 4 、 Figure 6 、 Figure 7 and Figure 8 As shown in

[0099] In some embodiments, optionally, the switch assembly 140 includes a housing 141 and a switch valve 143. Among them, the housing 141 is provided with a communication channel 142, and the communication channel 142 is communicated with the water pipe 130. The switch valve 143 is arranged in the communication channel 142, and the switch valve 143 can move between a first position and a second position. Based on the switch valve 143 being in the first position, the switch valve 143 and the housing 141 form a throttling channel 144, and the throttling channel 144 is communicated with the communication channel 142. Based on the switch valve 143 being in the second position, the switch valve 143 abuts against the housing 141, and the communication channel 142 is cut off.

[0099] In this embodiment, it is defined that the switch assembly 140 includes a housing 141 and a switch valve 143. Specifically, the housing 141 is provided with a communication channel 142, and the switch valve 143 is movably arranged in the communication channel 142.

[0100] Specifically, when the water level detection component 150 detects that the water in the water storage box 120 is lower than the first water level 161, it means that the water volume in the current water storage box 120 is insufficient and water needs to be added. At this time, the switch valve 143 moves to the first position and forms a throttling channel 144 with the housing 141. The external water source flows into the water storage box 120 through the water pipe 130, the communication channel 142 and the throttling channel 144 to increase the water volume in the water storage box 120. When the water level detection component 150 detects that the water in the water storage box 120 has been replenished to the second water level 162, it means that the water volume in the water storage box 120 has been replenished. At this time, the switch valve 143 moves to the second position and abuts against the housing 141, the throttling channel 144 is closed, and the communication channel 142 is cut off, and the water supply stops. Thus, the automatic water replenishment to the water storage box 120 is realized, and the cooking appliance 100 is prevented from cooking when the water storage box 120 is short of water, and the cooking performance of the cooking appliance 100 is ensured.

[0101] When the communication channel 142 is turned on, the communication channel 142 communicates with the throttling channel 144. That is to say, during the process of water flowing into the water storage box 120, throttling will be performed through the throttling channel 144, so that the water flow rate and velocity can be controlled, ensuring a stable and uniform water supply process, and avoiding large fluctuations in the water level 160 in the water storage box 120 due to large water pressure and rapid water flow, thereby preventing false alarms of the water level detection component 150. This is beneficial to further ensure the cooking performance of the cooking appliance 100 and improve the reliability of the cooking appliance 100.

[0102] As Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 shown, in some embodiments, optionally, the switching valve 143 includes a valve body 145 and a throttling member 146. Among them, based on the valve body 145 being in the first position, the throttling member 146 forms a throttling channel 144 with the housing 141. Based on the valve body 145 being in the second position, the valve body 145 pushes the throttling member 146 to move, so that the throttling member 146 abuts against the housing 141.

[0103] In this embodiment, it is defined that the switching valve 143 includes a valve body 145 and a throttling member 146. Specifically, when the water level detection component 150 detects that the water in the water storage box 120 is lower than the first water level 161, it means that the current amount of water in the water storage box 120 is insufficient and water needs to be added. At this time, the valve body 145 moves to the first position, and the throttling member 146 forms a throttling channel 144 with the housing 141. The external water source flows into the water storage box 120 through the water pipe 130, the communication channel 142, and the throttling channel 144 to increase the amount of water in the water storage box 120.

[0104] When the water level detection component 150 detects that the water in the water storage box 120 has been replenished to the second water level 162, it means that the replenishment of the water in the water storage box 120 is completed. At this time, the valve body 145 moves to the second position and pushes the throttling member 146 to abut against the housing 141. The throttling channel 144 is closed, and the communication channel 142 is cut off, stopping the water supply, thereby realizing automatic water replenishment into the water storage box 120, preventing the cooking appliance 100 from cooking when the water storage box 120 is short of water, and ensuring the cooking performance of the cooking appliance 100.

[0105] In some embodiments, optionally, the throttling member 146 includes an elastic member.

[0106] In this embodiment, since the throttling member 146 is an elastic member, when the switch assembly 140 is opened, that is, the connecting channel 142 is connected, the elastic member can adapt to different water pressures and produce different deformations, and the resulting deformation causes the cross-sectional area of the throttling channel 144 to change, thereby ensuring that the throttling channel 144 always maintains a specific flow rate, that is, the switch assembly 140 is a constant current switch, which is conducive to ensuring a stable and uniform water supply process, avoiding large water level 160 fluctuations in the water storage box 120 due to high water pressure and rapid water flow, and then causing the water level detection assembly 150 to falsely alarm, which is conducive to further ensuring the cooking performance of the cooking appliance 100 and improving the reliability of the cooking appliance 100.

[0107] Optionally, the elastic member includes a silicone pad.

[0108] like Figure 4 and Figure 5 As shown, in some embodiments, optionally, the housing 141 is further provided with a guide channel 147; the throttling member 146 includes a main body 148 and a guide portion 149, wherein the guide portion 149 is provided on a side of the main body 148 away from the valve body 145 and is at least partially located in the guide channel 147.

[0109] In this embodiment, the throttle member 146 includes a body 148 and a guide portion 149. Specifically, the guide portion 149 is disposed on a side of the body 148 facing away from the valve body 145, and at least a portion of the guide portion 149 is located within the guide channel 147. Since the valve body 145 moves, it can push the body 148 to form or seal the throttle channel 144 with the housing 141. During this process, the guide portion 149 located within the guide channel 147 can guide and limit the body 148. When the water in the water storage box 120 reaches the second water level 162, the throttle channel 144 formed by the body 148 and the housing 141 cannot be effectively sealed due to the body 148 being misaligned, thereby preventing the risk of overflow from the water storage box 120 due to continuous water supply, thereby further improving the reliability of the cooking appliance 100.

[0110] Optionally, the body 148 and the throttle member 146 are an integral structure.

[0111] like Figure 4 and Figure 6 As shown, in some embodiments, optionally, the connecting channel 142 includes a first connecting port 170 and a second connecting port 180, and the water pipe 130 includes a first pipe 131 and a second pipe 132, wherein the two ends of the first pipe 131 are respectively connected to the first connecting port 170 and the water source, and the two ends of the second pipe 132 are respectively connected to the second connecting port 180 and the water storage box 120; wherein, the first pipe 131 is a pressure-resistant pipe.

[0112] In this embodiment, it is defined that the water supply pipeline 130 includes a first pipeline 131 and a second pipeline 132. Specifically, one end of the first pipeline 131 communicates with the first communication port 170, and the other end of the first pipeline 131 communicates with a water source. One end of the second pipeline 132 communicates with the second communication port 180, and the other end of the second pipeline 132 communicates with the water storage box 120.

[0113] Specifically, when the water level detection component 150 detects that the water in the water storage box 120 is lower than the first water level 161, the switching valve 143 moves to the first position, and the water flow enters the water storage box 120 through the first pipeline 131, the communication channel 142, the throttling channel 144 and the second pipeline 132 respectively, so as to increase the water volume in the water storage box 120 and realize the automatic water supply of the cooking appliance 100.

[0114] Since the first pipeline 131 is a pressure-resistant pipeline, that is to say, the first pipeline 131 has certain pressure-resistant performance, so it can resist water pressure to a certain extent, prevent the first pipeline 131 from deforming, and is beneficial to extending the service life of the first pipeline 131.

[0115] Optionally, the first pipeline 131 includes a PE (Polyethylene) pipeline. Compared with the silicone hose used in the related art, the PE pipeline has good pressure-resistant performance, can prevent deformation, and is beneficial to extending the service life of the first pipeline 131.

[0116] As Figure 8 shown, in some embodiments, optionally, the cooking appliance 100 further includes a pipe joint 190. The pipe joint 190 is provided on the appliance body 110 and is exposed outside the appliance body 110. The other end of the water supply pipeline 130 communicates with the water source through the pipe joint 190.

[0117] In this embodiment, it is defined that the cooking appliance 100 further includes a pipe joint 190. Specifically, the water supply pipeline 130 is connected to the water source through the pipe joint 190. Optionally, the pipe joint 190 can be connected to a faucet or a water tank in the user's home to realize the supply of water source.

[0118] In some embodiments, optionally, the cooking appliance 100 further includes a controller, and any one of the water level detection component 150 and the switch component 140 is electrically connected to the controller.

[0119] In this embodiment, it is defined that the cooking appliance 100 further includes a controller. Specifically, the water level detection component 150 and the switch component 140 are respectively electrically connected to the controller.

[0120] Specifically, when the water level detection assembly 150 detects that the water in the water storage box 120 is below the first water level 161, the water level detection assembly 150 transmits a signal to the controller, which issues a command to control the switch assembly 140 to open, thereby connecting the water conduit 130. External water flows into the water storage box 120 through the water conduit 130 and the switch assembly 140, thereby increasing the water level in the water storage box 120. When the water level detection assembly 150 detects that the water in the water storage box 120 has been replenished to the second water level 162, indicating that the water in the water storage box 120 has been replenished, the water level detection assembly 150 transmits a signal to the controller, which issues a command to control the switch assembly 140 to close, thereby disconnecting the water conduit 130. This automatically replenishes water into the water storage box 120, preventing the cooking appliance 100 from cooking when the water storage box 120 is short of water, thereby ensuring the cooking performance of the cooking appliance 100.

[0121] When the water level detection component 150 detects that the water in the water storage box 120 reaches the third water level 163, it indicates that the switch component 140 has a malfunction. When the water in the water storage box 120 reaches the second water level 162, it is not closed in time, resulting in continuous water supply in the water storage box 120. The water level detection component 150 transmits an overflow signal to the controller. The controller controls the voice module of the cooking appliance 100 to issue a voice alarm, or controls the display module to display an alarm message, reminding the user that the switch component 140 is malfunctioning and the water storage box 120 is about to overflow. The water source can be manually turned off to ensure that the cooking appliance 100 has sufficient water in the water storage box 120 during cooking and does not overflow, which is beneficial to improving the user experience.

[0122] Optionally, the controller includes a main control board or a microprocessor.

[0123] like Figure 8 As shown, in some embodiments, optionally, the appliance body 110 is provided with a cooking cavity, and the cooking appliance 100 further includes a steam generator 210, which is communicated with the cooking cavity and the water storage box 120 respectively.

[0124] In this embodiment, the cooking appliance 100 further includes a steam generator 210. Specifically, the steam generator 210 is in communication with the cooking cavity and the water storage box 120. Specifically, during use of the cooking appliance 100, water in the water storage box 120 flows into the steam generator 210, where it is heated by a heating element within the steam generator 210 to form steam. The steam then enters the cooking cavity, steaming the food in the cooking cavity.

[0125] In a specific embodiment, optionally, the present invention provides an automatic water supply cooking appliance 100 based on a constant current solenoid valve (switch assembly 140) and a high-precision water level detection board (water level detection assembly 150), including: a cooking appliance main body (appliance body 110): a container for accommodating ingredients and water. A constant current solenoid valve (switch assembly 140): installed on the water supply pipe (water supply pipeline 130) of the cooking appliance 100 for controlling the water flow rate and velocity. A water tank (water storage box 120): for storing the water source for water supply. A high-precision water level detection board (water level detection assembly 150): for detecting the states of low water level (first water level 161), high water level (second water level 162), and overflow water level (third water level 163) in the cooking appliance (water storage box 120).

[0126] The whole machine working process includes four parts:

[0127] 1. Water supply process: When the cooking appliance 100 needs to add water, the high-precision water level detection board (water level detection assembly 150) detects that the water level 160 is lower than the preset value (first water level 161). The sensor (water level detection assembly 150) transmits the signal to the microprocessor (controller), and the microprocessor (controller) issues an instruction to control the constant current solenoid valve (switch assembly 140) to open, and the water source flows into the cooking appliance main body (water storage box 120) through the water supply pipe (water supply pipeline 130).

[0128] 2. Constant current control: The constant current solenoid valve (switch assembly 140) can achieve stable voltage and constant current output through the throttling principle, and precisely control the water flow rate and velocity to ensure a stable and uniform water supply process.

[0129] 3. Water level detection: The high-precision water level detection board (water level detection assembly 150) can detect the low water level (first water level 161), high water level (second water level 162), overflow water level (third water level 163) and the presence state of the water box, and transmit the detection results to the control system (controller).

[0130] 4. Automatic stop: When the water level 160 reaches the preset value (second water level 162), the high-precision water level detection board (water level detection assembly 150) detects the water level change. The sensor (water level detection assembly 150) transmits the signal to the microprocessor (controller), and the microprocessor (controller) issues an instruction to control the constant current solenoid valve (switch assembly 140) to close and stop the water supply.

[0131] Such as Figure 8 and Figure 9As shown, an automatic water supply cooking appliance 100 based on a constant current solenoid valve and a high-precision water level detection board includes a cooking appliance main body (appliance body 110), a constant current solenoid valve (switch assembly 140), a water tank (water storage box 120), a high-precision water level detection board (water level detection assembly 150), a joint (pipe joint 190), etc.

[0132] The constant current solenoid valve (switch assembly 140) is installed on the water supply pipe (water passing pipeline 130) to control the water flow. The water tank (water storage box 120) is used to store the water source for water supply. The high-precision water level detection board (water level detection assembly 150) is used to detect the low water level (first water level 161), high water level (second water level 162), overflow water level (third water level 163) in the cooking appliance 100, and the presence state of the water box. The water level signal is fed back by the water level detection board 155, and the main control board (controller) controls the opening and closing of the constant current solenoid valve (switch assembly 140).

[0133] As Figure 1 shown, when the cooking appliance 100 needs to add water, the high-precision water level detection board (water level detection assembly 150) detects that the water level 160 is lower than the preset value (first water level 161). The sensor (water level detection assembly 150) transmits the signal to the main control board (controller), which controls the constant current solenoid valve (switch assembly 140) to open. The water source flows into the cooking appliance cavity (water storage box 120) through the water supply pipe (water passing pipeline 130). The constant current solenoid valve (switch assembly 140) ensures a stable and uniform water supply process. When the water level 160 reaches the preset value (second water level 162), the high-precision water level detection board (water level detection assembly 150) detects the water level change. The sensor (water level detection assembly 150) transmits the signal to the main control board (controller), and the main control board issues an instruction to control the constant current solenoid valve (switch assembly 140) to close and stop the water supply. When the solenoid valve (switch assembly 140) has a functional abnormality and continuously supplies water to the overflow water level line (third water level 163), at this time, after the main control board (controller) receives the overflow signal, it controls the voice module to give a voice alarm.

[0134] As Figure 4 and Figure 5 shown, it is the internal structure schematic diagram of the constant current solenoid valve (switch assembly 140). The opening and closing of the water supply are achieved by the up and down movement of the valve core (valve body 145) to block the water outlet. A silicone pad (throttling part 146) is provided at the outlet end. Different deformations are generated by adapting to different water pressures, and the deformation causes the cross-sectional area of the water outlet (throttling channel 144) to change, so as to ensure that the gap always maintains a specific water flow at the water outlet.
