[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0034] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0035] The cooking equipment includes a cooking main unit and a storage tank. The cooking main unit includes a centrifugal pump and a heating element. During cooking, the liquid in the storage tank enters the cooking main unit under the action of the centrifugal pump, is heated by the heating element, and then the heated liquid is returned to the storage tank by the centrifugal pump. The heated liquid mixes with the liquid in the storage tank, thereby heating the liquid in the storage tank and cooking the food in the storage tank.
[0036] Centrifugal pumps utilize the centrifugal motion of an impeller to transport liquids. Before starting a centrifugal pump, the pump casing and piping must be filled with liquid. Then, the pump motor is started, causing the pump shaft to drive the impeller and liquid in high-speed rotation. The liquid undergoes centrifugal motion, being thrown towards the outer edge of the impeller and flowing into the pump piping through the flow channel of the volute casing. Therefore, before starting the centrifugal pump, an air pump is used to create negative pressure in the entire circulating liquid system, drawing liquid from the storage tank to the centrifugal pump. A storage tank connected to the circulating liquid system is installed. When the liquid level in the storage tank reaches a preset threshold, the centrifugal pump is considered full. At this point, the air pump can be turned off and the centrifugal pump started, driving the liquid to flow through the circulating liquid system. To determine whether the liquid level in the storage tank has reached the preset threshold, a liquid level detection component is used to monitor the liquid level in the storage tank.
[0037] Liquid level detection components typically include multiple electrodes. When detecting liquid level, the component triggers detection if at least two electrodes simultaneously come into contact with the liquid. However, due to the high sensitivity of the electrodes, triggering can occur when a momentary jet of liquid connects at least two electrodes, or when fluctuations in the liquid surface cause contact with at least two electrodes. In such cases, the actual liquid level may not have reached the system's required value, leading to false triggering of the liquid level detection component.
[0038] To address this, the present invention provides a cooking device, a liquid storage device, and a liquid storage structure to prevent the liquid level detection component from erroneously triggering the detection of the liquid level and to improve the accuracy of liquid level detection.
[0039] Please see Figure 1 and Figure 2 This invention provides a cooking device including a cooking main unit (not shown) and a liquid storage tank 100. The cooking main unit includes a heating device (not shown) and a liquid storage device 200. The heating device is used to draw liquid from the liquid storage tank 100 out of the tank for heating and to return the heated liquid to the tank 100. The liquid storage device 200 includes a liquid storage chamber 10, a liquid level detection component 20, and a liquid blocking structure 30. The liquid storage chamber 10 is connected to the heating pipe 101 of the heating device. The liquid level detection component 20 is at least partially disposed within the liquid storage chamber 10 and includes a first electrode 21 and a second electrode 22. When the first electrode 21 and the second electrode 22 simultaneously contact the liquid, the liquid level detection component 20 generates a liquid level detection signal. The liquid blocking structure 30 is disposed within the liquid storage chamber 10 and is used to prevent liquid fluctuations and / or liquid splashes within the liquid storage chamber 10 from being simultaneously transmitted to the first electrode 21 and the second electrode 22.
[0040] In the cooking device of the above embodiment, since the liquid blocking structure 30 can block liquid splashing and / or liquid level fluctuations in the liquid storage tank 10 from being transmitted to the first electrode 21 and the second electrode 22 at the same time, it can prevent the liquid level detection component 20 from being falsely triggered to detect the liquid level and improve the accuracy of liquid level detection.
[0041] For example, preventing liquid fluctuations and / or liquid splashes within the liquid storage tank 10 from being simultaneously transmitted to the first electrode 21 and the second electrode 22 includes the following three schemes: preventing liquid fluctuations within the liquid storage tank 10 from being simultaneously transmitted to the first electrode 21 and the second electrode 22; preventing liquid splashes within the liquid storage tank 10 from being simultaneously transmitted to the first electrode 21 and the second electrode 22; and preventing both liquid fluctuations and liquid splashes within the liquid storage tank 10 from being simultaneously transmitted to the first electrode 21 and the second electrode 22.
[0042] For example, preventing liquid fluctuations and / or liquid splashes within the liquid storage tank 10 from being simultaneously transmitted to the first electrode 21 and the second electrode 22 includes: preventing liquid fluctuations and / or liquid splashes within the liquid storage tank 10 from simultaneously contacting the first electrode 21 and the second electrode 22.
[0043] Please see Figure 3 In some embodiments, the liquid storage tank 10 is provided with a liquid inlet 11 communicating with the heating pipe 101. The liquid blocking structure 30 includes a liquid blocking component 31. The liquid inlet 11 is located on one side of at least a portion of the liquid blocking component 31, and the second electrode 22 is located on the other opposite side of at least a portion of the liquid blocking component 31. In this way, the liquid blocking component 31 can both prevent liquid ejected from the liquid inlet 11 from splashing onto the second electrode 22 and prevent liquid level fluctuations caused by adding liquid from the liquid inlet 11 into the liquid storage tank 10 from being transmitted to the second electrode 22. This can prevent liquid splashing and / or liquid level fluctuations in the liquid storage tank 10 from simultaneously contacting the first electrode 21 and the second electrode 22, and prevent the liquid level detection component 20 from erroneously triggering the detection of the liquid level.
[0044] Please see Figure 2 and Figure 3In some embodiments, the liquid storage tank 10 includes a first tank body 12 and a second tank body 13. An inlet 11 is located on the first tank body 12, and the second tank body 13 is connected to the first tank body 12. The liquid level detection component 20 is mounted on the second tank body 13. The first electrode 21 and the inlet 11 are located on one side of at least a portion of the liquid blocking component 31, and the second electrode 22 is located on the opposite side of at least a portion of the liquid blocking component 31. Thus, even if liquid ejected from the inlet 11 easily splashes onto the first electrode 21, or if liquid level fluctuations caused by adding liquid from the inlet 11 are easily transmitted to the first electrode 21, the liquid blocking component 31 can prevent liquid ejected from the inlet 11 from splashing onto the second electrode 22, and can also prevent liquid level fluctuations caused by adding liquid from the inlet 11 into the liquid storage tank 10 from being transmitted to the second electrode 22. This prevents false triggering of detection caused by liquid splashing and / or liquid level fluctuations simultaneously being transmitted to the first electrode 21 and the second electrode 22, thereby improving the accuracy of liquid level detection.
[0045] For example, the first compartment 12 and the second compartment 13 are connected by at least one of the following methods: adhesive connection, magnetic connection, screw connection, snap-fit connection, etc.
[0046] Please see Figures 2 to 4 In some embodiments, the liquid blocking assembly 31 includes a first blocking wall 311 and a second blocking wall 312. The first blocking wall 311 protrudes from the first chamber 12, and the second blocking wall 312 protrudes from the second chamber 13. The first electrode 21 and the liquid inlet 11 are located on one side of the first blocking wall 311 and the second blocking wall 312, and the second electrode 22 is located on the opposite side of the first blocking wall 311 and the second blocking wall 312. The first blocking wall 311 and the second blocking wall 312 at least partially overlap along the liquid level height direction. This effectively prevents splashed liquid or liquid level fluctuations from being transmitted to the second electrode 22 through the gap between the first blocking wall 311 and the second blocking wall 312, effectively preventing the liquid level detection assembly 20 from falsely triggering the detection of the liquid level, and further improving the accuracy of liquid level detection. In addition, the first blocking wall 311 and the second blocking wall 312 are separated from each other, which facilitates the assembly between the first chamber 12 and the second chamber 13 while ensuring the blocking of liquid splashes and / or liquid level fluctuations.
[0047] Please see Figure 2 In some embodiments, the first barrier wall 311 intersects or is perpendicular to the arrangement direction of the first electrode 21 and the second electrode 22, and the second barrier wall 312 intersects or is perpendicular to the arrangement direction of the first electrode 21 and the second electrode 22. This provides a guarantee for the liquid barrier assembly 31 to prevent liquid fluctuations and / or liquid splashes from being simultaneously transmitted to the first electrode 21 and the second electrode 22.
[0048] Please see Figure 2For example, the first barrier wall 311 and the second barrier wall 312 are spaced apart along the arrangement direction of the first electrode 21 and the second electrode 22, which provides a guarantee that the first barrier wall 311 and the second barrier wall 312 at least partially overlap along the liquid level height direction.
[0049] Understandably, if the distance between the first barrier wall 311 and the second barrier wall 312 along the arrangement direction of the first electrode 21 and the second electrode 22 is too large, splashed liquid or liquid level fluctuations can easily be transmitted to the second electrode 22 through the gap between them, causing false triggering of detection. In some embodiments, the distance between the first barrier wall 311 and the second barrier wall 312 along the arrangement direction is greater than zero and less than or equal to a preset distance threshold to effectively prevent false triggering of detection by the liquid level detection component 20. This preset distance threshold can be set according to actual needs, for example, greater than zero and less than or equal to 1 mm.
[0050] In other embodiments, the second barrier wall 312 may be omitted, and the first barrier wall 311 protrudes from the bottom wall of the first compartment 12, with the side surface of the first barrier wall 311 away from the bottom wall of the first compartment 12 in contact with the second compartment 13; or, the distance between the side surface of the first barrier wall 311 away from the bottom wall of the first compartment 12 and the second compartment 13 is greater than zero and less than or equal to a preset threshold, such as 3mm.
[0051] Please see Figure 5 In some embodiments, the liquid blocking assembly 31 includes a first blocking wall 311 and a shielding wall 313. The first blocking wall 311 protrudes from the bottom wall of the first chamber 12 and intersects with the arrangement direction of the first electrode 21 and the second electrode 22. The first blocking wall 311 is used to block liquid fluctuations and / or liquid splashes from entering through the liquid inlet 11 and being transmitted to the second electrode 22. The shielding wall 313 is correspondingly disposed to the liquid inlet 11 and is connected to the first blocking wall 311 and the first chamber 12. The first electrode 21 passes through the shielding wall 313, which is used to block liquid ejected from the liquid inlet 11 from splashing onto the second electrode 22. It can be understood that the shielding wall 313, the first blocking wall 311, and a portion of the sidewall of the first chamber 12 form an enclosed cavity (not shown). The shielding wall 313 prevents the liquid ejected from the inlet 11 from splashing upwards and falling onto the second electrode 22. When the liquid ejected from the inlet 11 splashes upwards onto the shielding wall 313, the shielding wall 313 changes the direction or tendency of the liquid's movement. The first blocking wall 311 can also change the direction or tendency of the liquid splashing onto the first blocking wall 311, causing the splashed liquid to fall back into the enclosed cavity or not splash towards the second electrode 22. For example, Figure 5 The straight arrow in the diagram indicates the direction of liquid flow.
[0052] Please see Figure 5In some embodiments, the shielding wall 313, the liquid inlet 11, and the first electrode 21 are all located on one side of the first shielding wall 311, and the second electrode 22 is located on the opposite side of the first shielding wall 311. This minimizes the amount of liquid splashing and / or liquid level fluctuations caused by the liquid ejected from the liquid inlet 11 that are transmitted to the second electrode 22, further improving the probability of preventing false triggering of detection and thus further improving the accuracy of liquid level detection.
[0053] Please see Figure 2 and Figure 3 In some embodiments, the liquid barrier structure 30 further includes a baffle assembly 32. One end of the baffle assembly 32 is connected to the liquid reservoir 10 and / or the liquid barrier assembly 31. The other end of the baffle assembly 32 extends at least partially toward the alignment direction of the first electrode 21 and the second electrode 22 to slow the flow of liquid toward the detection area of the second electrode 22.
[0054] Please see Figure 2 and Figure 3 For example, the liquid blocking assembly 31 is used to block liquid fluctuations and / or liquid splashes within the liquid storage tank 10 from being transmitted to the second electrode 22 along a first direction. The baffle assembly 32 is used to slow down the liquid flow along a second direction and is capable of blocking continuous liquid columns or splashes of liquid ejected in the second direction.
[0055] For example, the second direction is perpendicular to the first direction. The liquid level height direction is perpendicular to the plane containing the first and second directions.
[0056] For example, the first direction is the arrangement direction of the first electrode 21 and the second electrode 22.
[0057] For example, the first direction is as follows Figure 2 In the X direction, the second direction is as follows Figure 2 in the Y direction.
[0058] Please see Figure 2 and Figure 3 In some embodiments, the partition assembly 32 includes a partition member 321, which protrudes into the liquid storage tank 10. One end of the partition member 321 is connected to the liquid blocking assembly 31. The partition member 321 and the first side wall 14 of the liquid storage tank 10 are spaced apart and opposite to each other. The partition member 321 and the second electrode 22 are located on one side of the first blocking wall 311, and the first electrode 21 and the liquid inlet 11 are located on the other opposite side of the first blocking wall 311.
[0059] Please refer to 3. Figure 4 and Figure 6For example, the liquid storage tank 10 includes a first sidewall 14, a second sidewall 15, a third sidewall 16, and a fourth sidewall 17. The first sidewall 14 is opposite to the fourth sidewall 17, and the second sidewall 15 is opposite to the third sidewall 16. The first sidewall 14, the second sidewall 15, the fourth sidewall 17, and the third sidewall 16 are connected in sequence. The partition member 321 is spaced apart from the first sidewall 14 of the liquid storage tank 10 to form a flow channel for liquid to flow through. The liquid inlet 11 is located close to the fourth sidewall 17 to slow down the liquid flow as much as possible and prevent liquid level fluctuations caused by adding liquid from the liquid inlet 11 from being transmitted to the second electrode 22.
[0060] Please refer to 3. Figure 4 and Figure 6 In some embodiments, the partition member 321 includes a first partition 3211 and a second partition 3212. The first partition 3211 protrudes from the first chamber 12 of the liquid storage tank 10 and is connected to the first barrier wall 311 of the liquid barrier assembly 31. The second partition 3212 protrudes from the second chamber 13 of the liquid storage tank 10 and is connected to the second barrier wall 312 of the liquid barrier assembly 31. The first partition 3211 and the second partition 3212 at least partially overlap along the liquid level height direction. This prevents liquid level fluctuations from being transmitted to the second electrode 22 through the gap between the first partition 3211 and the second partition 3212, further preventing the liquid level detection assembly 20 from falsely triggering liquid level detection and effectively improving the accuracy of liquid level detection.
[0061] Please refer to 3. Figure 4 and Figure 6 For example, the first partition 3211 and the second partition 3212 are spaced apart along a second direction. If the gap between the first partition 3211 and the second partition 3212 along the second direction is too large, liquid level fluctuations can easily be transmitted through the gap between them to the second electrode 22, causing false triggering of detection. In some embodiments, the spacing between the first partition 3211 and the second partition 3212 along the arrangement direction is greater than zero and less than or equal to a preset distance threshold to further prevent false triggering of detection by the liquid level detection component 20. This preset distance threshold can be set according to actual needs, for example, greater than zero and less than or equal to 1 mm.
[0062] Please see 3 and Figure 6In some embodiments, the partition assembly 32 further includes a third partition 322. The third partition 322 protrudes from the first chamber 12 of the liquid storage tank 10 and is connected to the second side wall 15 of the liquid storage tank 10. The liquid inlet 11 and the first electrode 21 are located on one side of the first barrier wall 311, and the third partition 322 and the second electrode 22 are both located on the opposite side of the first barrier wall 311. The partition 321, the third partition 322, and the second electrode 22 are arranged sequentially at intervals along a preset direction, which is perpendicular to the arrangement direction of the first electrode 21 and the second electrode 22. The third partition 322 can further slow down the liquid flow and prevent liquid level fluctuations along the preset direction from being transmitted to the second electrode 22, further preventing false triggering of detection.
[0063] For example, the preset direction is the second direction.
[0064] Please see 3 and Figure 6 In some embodiments, the partition assembly 32 includes a fourth partition 323. The fourth partition 323 protrudes from the first chamber 12 of the liquid storage tank 10 and is connected to the first barrier wall 311 of the liquid barrier assembly 31. The fourth partition 323, the first electrode 21, and the liquid inlet 11 are all located on one side of the first barrier wall 311, and the second electrode 22 is located on the opposite side of the second barrier wall 312. The fourth partition 323 can slow down the liquid flow rate and prevent the continuous liquid column ejected instantaneously from the liquid inlet 11 from splashing in the second direction, further realizing the prevention of false triggering detection.
[0065] Please see Figure 6 For example, the first partition 3211, the second partition 3212, the third partition 322, the fourth partition 323, the liquid blocking assembly 31, and the sidewall of the liquid storage tank 10 cooperate to form a bent liquid channel for liquid flow. The bent liquid channel can slow down the liquid flow speed, and to a certain extent prevent the continuous liquid column ejected from the liquid inlet 11 from splashing in the second direction to the second electrode 22, and prevent the liquid level fluctuation caused by adding liquid from the liquid inlet 11 from being transmitted to the second electrode 22 in the second direction. For example, Figure 6 The direction of the straight arrow in the middle indicates the direction of liquid flow.
[0066] In some embodiments, the installation height of the first electrode 21 along the liquid level direction is less than the installation height of the second electrode 22 along the liquid level direction. The first electrode 21 is used to receive a drive signal transmitted from the circuit board (not shown), which can be 5V, etc. When the liquid level reaches a preset threshold, the circuit loop formed by the circuit board, the first electrode 21, the liquid, and the second electrode 22 is turned on, and the second electrode 22 is used to send a liquid level signal to the circuit board. Thus, even if the liquid level in the storage tank 10 does not reach the preset threshold, and even if the liquid in the storage tank 10 itself has a certain conductivity or the storage tank 10 is not a completely insulating material, the liquid level detection component 20 of this embodiment will not be falsely triggered to detect the liquid level, further improving the accuracy of liquid level detection.
[0067] For example, the first electrode 21 is positioned lower than the second electrode 22 at the bottom of the liquid storage tank 10.
[0068] Please see Figure 2 and Figure 3 Exemplarily, the liquid storage tank 10 has a first mounting position 18 and a second mounting position 19. The first mounting position 18 is used to mount a first electrode 21, and the second mounting position 19 is used to mount a second electrode 22. Exemplarily, at least a portion of the liquid blocking assembly 31 divides the first tank 12 into a first liquid storage tank 121 and a second liquid storage tank 122, with the first liquid storage tank 121 communicating with the second liquid storage tank 122. The first mounting position 18 and the second mounting position 19 are located on the second tank 13. The first electrode 21 is mounted at the first mounting position 18 and extends into the first liquid storage tank 121, and the second electrode 22 is mounted at the second mounting position 19 and extends into the second liquid storage tank 122. The second tank 13 covers the first liquid storage tank 121 and the second liquid storage tank 122.
[0069] Please see Figure 7 In some embodiments, the liquid level detection component 20 includes a float valve sensor 23, and a mounting position (not shown) is provided in the liquid storage tank 10, where the float valve sensor 23 is located. When the liquid level rises to a preset threshold, the internal circuit of the float valve sensor 23 is turned on, thereby generating a liquid level detection signal.
[0070] Please see Figure 8 In some embodiments, the liquid level detection component 20 includes a capacitor module 24 disposed on the outer wall of the liquid storage tank 10. The capacitor module 24 is used to generate a liquid level detection signal when the liquid level reaches a preset threshold. For example, the capacitor module 24 is attached to the side wall of the liquid storage tank 10. Since the capacitance values of air and liquid are different, a liquid level detection signal can be generated by the change in capacitance value, thereby detecting the liquid level. For example, the capacitor module 24 is disposed on the outer wall of one side of the liquid storage tank 10.
[0071] Please see Figure 2For example, the distance between the first electrode 21 and the bottom wall of the first liquid storage tank 121 is less than the distance between the second electrode 22 and the bottom wall of the second liquid storage tank 122.
[0072] Please see Figure 2 For example, the bottom wall of the first liquid storage tank 121 is lower than the bottom wall of the second liquid storage tank 122 along the liquid level height direction.
[0073] Please see Figure 2 For example, the height of the end of the first electrode 21 away from the second chamber 13 along the liquid level height direction is less than the height of the end of the second electrode 22 away from the second chamber 13 along the liquid level height direction.
[0074] Please see Figure 2 For example, the second compartment 13 is inclined downward from the second mounting position 19 toward the first mounting position 18.
[0075] Please see Figure 1 In some embodiments, the heating device includes a heating pipe 101, a centrifugal pump 102, and a heating element 103. The heating pipe 101 is connected to a storage tank 100. The centrifugal pump 102 provides power for the liquid flow in the heating pipe 101, and the heating element 103 heats the liquid in the heating pipe 101. The cooking device also includes an air pump 300 for creating negative pressure by evacuating air from the heating pipe 101. During cooking, the liquid in the storage tank 100 flows to the heating pipe 101 under the action of the centrifugal pump 102 and then flows through the heating element 103 for heating. The heated liquid is then returned to the storage tank 100 via the heating pipe 101, where it mixes with the liquid in the storage tank 100, thereby heating the liquid in the storage tank 100 and thus cooking the food in the storage tank 100. The air pump 300 is used to evacuate air from the heating pipe 101 to create a negative pressure, providing initial power for the liquid to flow within the heating pipe 101. This allows the liquid to fill the centrifugal pump 102, ensuring that the centrifugal pump 102 can normally provide power for the liquid to flow within the heating pipe 101 after startup. When the liquid level detection component 20 detects that the liquid level in the liquid storage tank 10 is at a preset threshold, the centrifugal pump 102 is filled with liquid. At this time, the air pump 300 can be turned off and the centrifugal pump 102 can be started. After the centrifugal pump 102 starts, it can drive the liquid to flow in the circulating liquid circuit system formed by the liquid storage tank 100, the heating pipe 101, the centrifugal pump 102, and the heating element 103.
[0076] Please see Figure 2The present invention also provides a liquid storage device 200 for a cooking main unit, the cooking main unit including a heating device. The heating device is used to heat the liquid inside the cooking main unit and lead the heated liquid out of the cooking main unit. The liquid storage device 200 includes a liquid storage tank 10, a liquid level detection component 20, and a liquid blocking structure 30. The liquid level detection component 20 is disposed in the liquid storage tank 10 and is used to generate a liquid level detection signal when the liquid level reaches a preset threshold. The liquid blocking structure 30 is disposed inside the liquid storage tank 10 and is used to prevent liquid splashing and / or liquid level fluctuations in the liquid storage tank 10 from being transmitted to at least a portion of the liquid level detection component 20.
[0077] The liquid storage device 200 of the above embodiment has a liquid blocking structure 30 disposed in the liquid storage tank 10. The liquid blocking structure 30 is used to block liquid splashing and / or liquid level fluctuations in the liquid storage tank 10 from being transmitted to at least part of the liquid level detection component 20. Therefore, it prevents the liquid level detection component 20 from erroneously triggering the detection of the liquid level and improves the accuracy of liquid level detection.
[0078] For example, the liquid storage device 200 includes the liquid storage device 200 of any of the above embodiments.
[0079] For example, at least a portion of the liquid level detection component 20 is disposed within the liquid storage tank 10.
[0080] In some embodiments, the liquid level detection component 20 includes a first electrode 21 and a second electrode 22. When the first electrode 21 and the second electrode 22 simultaneously contact the liquid, the liquid level detection component 20 generates a liquid level detection signal. The liquid storage device 200 also includes a liquid blocking mechanism 30, which is used to prevent liquid fluctuations and / or liquid splashes within the liquid storage tank 10 from being simultaneously transmitted to the first electrode 21 and the second electrode 22. Since the liquid blocking structure 30 can prevent liquid splashes and / or liquid level fluctuations within the liquid storage tank 10 from being simultaneously transmitted to the first electrode 21 and the second electrode 22, it prevents the liquid level detection component 20 from falsely triggering the detection of the liquid level, thereby improving the accuracy of liquid level detection.
[0081] Please see Figure 7 In some embodiments, the liquid level detection component 20 includes a float valve sensor 23, and a mounting position (not shown) is provided in the liquid storage tank 10, where the float valve sensor 23 is located. When the liquid level rises to a preset threshold, the internal circuit of the float valve sensor 23 is turned on, thereby generating a liquid level detection signal.
[0082] Please see Figure 8In some embodiments, the liquid level detection component 20 includes a capacitor module 24 disposed on the outer wall of the liquid storage tank 10. The capacitor module 24 is used to generate a liquid level detection signal when the liquid level reaches a preset threshold. For example, the capacitor module 24 is attached to the side wall of the liquid storage tank 10. Since the capacitance values of air and liquid are different, a liquid level detection signal can be generated by the change in capacitance value, thereby detecting the liquid level. For example, the capacitor module 24 is disposed on the outer wall of one side of the liquid storage tank 10.
[0083] In some embodiments, the liquid storage tank 10 is provided with a liquid inlet 11 communicating with the heating pipe 101; the liquid blocking structure 30 includes: a liquid blocking component 31, the liquid inlet 11 being located on one side of at least a portion of the liquid blocking component 31, and a second electrode 22 being located on the other opposite side of at least a portion of the liquid blocking component 31.
[0084] In some embodiments, the liquid storage tank 10 includes a first tank body 12 and a second tank body 13, with an inlet 11 disposed on the first tank body 12. The second tank body 13 is connected to the first tank body 12, and a liquid level detection component 20 is mounted on the second tank body 13; the first electrode 21 and the inlet 11 are located on one side of at least a portion of the liquid blocking component 31, and the second electrode 22 is disposed on the other opposite side of at least a portion of the liquid blocking component 31.
[0085] In some embodiments, the liquid blocking assembly 31 includes a first blocking wall 311 and a second blocking wall 312. The first blocking wall 311 protrudes from the first chamber 12, and the second blocking wall 312 protrudes from the second chamber 13. The first blocking wall 311 and the second blocking wall 312 at least partially overlap along the liquid level height direction. The first electrode 21 and the liquid inlet 11 are located on one side of the first blocking wall 311 and the second blocking wall 312, and the second electrode 22 is located on the other opposite side of the first blocking wall 311 and the second blocking wall 312.
[0086] In some embodiments, the liquid blocking assembly 31 includes a first blocking wall 311 and a shielding wall 313. The first blocking wall 311 protrudes from the bottom wall of the first chamber 12 and intersects the arrangement direction of the first electrode 21 and the second electrode 22, and is used to block liquid fluctuations and / or liquid splashes from being introduced from the liquid inlet 11 and transmitted to the second electrode 22. The shielding wall 313 is correspondingly disposed to the liquid inlet 11 and is connected to the first blocking wall 311 and the first chamber 12. The first electrode 21 passes through the shielding wall 313, and the shielding wall 313 is used to block liquid ejected from the liquid inlet 11 from splashing onto the second electrode 22.
[0087] In some embodiments, the liquid barrier structure 30 further includes a baffle assembly 32. One end of the baffle assembly 32 is connected to the liquid storage tank 10 and / or the liquid barrier assembly 31, and the other end extends at least partially toward the arrangement direction of the first electrode 21 and the second electrode 22, for slowing down the liquid flow toward the detection area of the second electrode 22.
[0088] In some embodiments, both the first electrode 21 and the second electrode 22 include electrode sensors. The installation height of the first electrode 21 along the liquid level direction is less than that of the second electrode 22 along the liquid level direction. The first electrode 21 is used to receive a power supply signal, and the second electrode 22 is used to receive a liquid level signal. Thus, even if the liquid level in the storage tank 10 does not reach a preset threshold, and even if the liquid in the storage tank 10 itself has a certain degree of conductivity or the storage tank 10 is not a completely insulated body, the liquid level detection component 20 of this embodiment will not be falsely triggered to detect the liquid level, further improving the accuracy of liquid level detection.
[0089] Please see Figure 2 This invention also provides a liquid storage structure for a cooking device. The liquid storage structure includes a liquid storage tank 10 and a liquid blocking structure 30. The liquid storage tank 10 has a first mounting position 18 and a second mounting position 19 for mounting a first electrode 21 and a second electrode 22 of a liquid level detection component 20, respectively. When the first electrode 21 and the second electrode 22 simultaneously contact the liquid, the liquid level detection component 20 generates a liquid level detection signal. The liquid blocking structure 30 is disposed within the liquid storage tank 10 to prevent liquid fluctuations and / or liquid splashes within the liquid storage tank 10 from being simultaneously transmitted to the first electrode 21 and the second electrode 22.
[0090] The liquid storage structure of the above embodiment, since the liquid blocking structure 30 can block liquid splashing and / or liquid level fluctuations in the liquid storage tank 10 from being transmitted to the first electrode 21 and the second electrode 22 at the same time, can prevent the liquid level detection component 20 from being falsely triggered to detect the liquid level and improve the accuracy of liquid level detection.
[0091] For example, the liquid storage tank 10 includes the liquid storage tank 10 of any of the above embodiments. The liquid barrier structure 30 includes the liquid barrier structure 30 of any of the above embodiments.
