Description

Technical Field

[0001] The present application relates to the field of household appliances, and in particular to a liquid heating container. Background Art

[0002] Existing liquid heating containers are usually provided with glass windows, which are convenient for users to observe the liquid level in the container through the glass windows. However, due to the complex installation structure of the glass window and the problem of other structures of the container blocking the line of sight, the glass window is not convenient for users to observe when the water level is low. Utility Model Content

[0003] The present application provides a liquid heating container, which can solve the problem in the prior art that the transparent window makes it inconvenient to observe the low water level situation in the container.

[0004] The present application provides a liquid heating container, comprising

[0005] The shell is provided with a water outlet;

[0006] An inner liner is installed in the shell, and a water hole is provided at the bottom of the inner liner;

[0007] A water outlet pipe is installed in the shell, and two ends of the water outlet pipe are respectively connected with the water hole and the water outlet;

[0008] A liquid level detection component is installed in the shell, and the liquid level detection component includes a liquid level sensor. The liquid level sensor is attached to the outer wall of the water outlet pipe and is used to detect the liquid level in the water outlet pipe.

[0009] In the above scheme, the water outlet pipe connects the inner tank with the water outlet. When the user takes water, the cup can be placed under the water outlet, and the water in the inner tank can flow into the cup through the water outlet pipe and the water outlet. The water outlet pipe is located in the gap between the shell and the inner tank. When the user does not take water, the water outlet pipe can form a connecting vessel with the inner tank. The liquid level in the water outlet pipe is flush with the liquid level in the inner tank. The liquid level sensor is a non-contact sensor, which is arranged on the outer wall of the water outlet pipe. The liquid level in the water outlet pipe can be detected, thereby judging the liquid level in the inner tank. Specifically, when the liquid level in the water outlet pipe exceeds the bottom of the liquid level sensor and when the liquid level in the water outlet pipe is lower than the bottom of the liquid level sensor, the signal generated by the liquid level sensor is different. By monitoring the signal of the liquid level sensor, the liquid level in the inner tank can be judged. Therefore, the liquid level sensor can be arranged at the bottom of the water outlet pipe to realize the low liquid level detection function of the liquid heating container.

[0010] The liquid heating container provided by the present application can determine whether the liquid level in the inner tank is too low by detecting whether the signal of the liquid level sensor changes. It does not require the user to observe with the naked eye, and the judgment result is more accurate, which makes the user experience better. There is no need to set a transparent window on the shell, which can simplify the structure of the shell, and the water outlet pipe does not need to be provided with a glass tube part, which can also simplify the structure of the water outlet pipe and reduce the risk of leakage caused by the splicing pipeline. In addition, the transparent window in the prior art needs to be supported by the bracket structure on the shell. Due to the limitation of the height of the bracket, in order to see the bottom of the inner tank clearly, the height of the inner tank cannot be set too low, which will cause the volume of the inner tank to be reduced and cause waste of space at the bottom of the shell. Therefore, the liquid heating container of the present application cancels the transparent window, which is conducive to increasing the depth of the inner tank, thereby increasing the volume of the inner tank. In addition, in the liquid heating container provided by the present application, the water outlet pipe is used as the water outlet pipeline of the liquid when the liquid heating container is discharged, and as the liquid level detection pipeline when the liquid level is detected, achieving the effect of the two-in-one of the water outlet pipeline and the detection pipeline, and there is no need to set a liquid level detection pipeline separately, which further simplifies the structure of the liquid heating container.

[0011] In a possible design, the liquid level sensor is a copper ring, and the copper ring is sleeved outside the water outlet pipe; the inner wall of the copper ring fits with the outer wall of the water outlet pipe.

[0012] In the above scheme, the copper ring is relatively small in size. When it is installed on the outside of the water outlet pipe, it can further save space. The inner wall of the copper ring fits the water outlet pipe, which can improve the installation stability of the copper ring and prevent the copper ring from shifting after the liquid container is shaken, which is beneficial to improving the detection accuracy of the liquid level sensor.

[0013] In a possible design, the liquid level sensor is a copper ring, and along the axial direction of the copper ring, one end of the copper ring is in contact with the outer wall of the water outlet pipe.

[0014] In the above scheme, the copper ring is small in size, which can save the internal space of the liquid heating container. The copper ring itself has a relatively simple structure and high flexibility, and can adapt to different installation positions. When the copper ring is fixed on the outer wall of the water outlet pipe, the installation of the liquid level sensor can be more convenient.

[0015] In a possible design, the water outlet pipe is made of insulating material.

[0016] In the above scheme, the water in the water outlet pipe is a conductive liquid. When using a capacitive sensor for liquid level detection, an insulating container must be used. Therefore, the water outlet pipe should be made of insulating material, otherwise it will affect the accuracy of liquid level detection.

[0017] In a possible design, the water outlet pipe has a lowest liquid level line, and along the height direction of the liquid heating container, the bottom end of the liquid level sensor is flush with the lowest liquid level line in the water outlet pipe.

[0018] In the above scheme, the lowest liquid level line of the water outlet pipe is the lowest liquid level line of the inner tank. When the liquid in the water outlet pipe is lower than the lowest liquid level line, the detection signal of the liquid level sensor will change. The detection control board can thus determine whether the liquid level in the inner tank is too low. Therefore, the height of the preset lowest liquid level can be adjusted by adjusting the height position of the liquid level sensor on the water outlet pipe.

[0019] In a possible design, the liquid level detection assembly further includes a detection control board, and the liquid level sensor is electrically connected or signal-connected to the detection control board.

[0020] In the above scheme, the detection control board is used to receive the signal sent by the liquid level sensor, and judge the liquid level in the inner tank according to the signal, thereby outputting a signal to control other electrical components in the liquid heating container to turn on or off, so as to realize automatic control of the liquid heating container.

[0021] In a possible design, the liquid heating container also includes a display operation component, which includes a display panel and a display control board, and the display panel is electrically connected or signal-connected to the display control board; the display control board is electrically connected or signal-connected to the liquid level sensor, and is electrically connected or signal-connected to the detection control board, and the display control board is used to process the detection results of the liquid level sensor and output the processing results to the detection control board.

[0022] In the above scheme, when the user takes water, the display control board only receives the signal from the display panel but does not receive the signal from the liquid level sensor, or receives the signal from the liquid level sensor but does not process the signal, that is, the display control board can control the liquid heating container not to perform liquid level detection in the water taking state. When the user does not take water, the display control board can be used to receive the signal from the display panel and the liquid level sensor. The display control board can process the signal sent by the liquid level sensor and compare it with the preset low liquid level signal reference value, and output the comparison result to the detection control board. The detection control board can determine whether the liquid level in the inner tank is lower than the preset height according to the signal output by the display control board, and then send instructions to the output module according to the determination result.

[0023] In a possible design, the liquid heating container also includes an alarm, which is electrically or signal-connected to the detection control board; the detection control board is used to control the alarm to be turned on or off according to the detection result of the liquid level sensor.

[0024] In the above scheme, the alarm is electrically or signal-connected to the detection control board. When the detection control board determines that the liquid level is too low, it can send an instruction to the alarm to control the alarm to turn on, and remind the user through the alarm that the liquid level in the inner tank is too low. When the detection control board determines that the liquid level is too normal, it can send an instruction to the alarm to control the alarm to turn off.

[0025] In a possible design, the shell is further provided with a vent hole connected to the outside, and the vent hole is connected to the water outlet pipe through a vent pipe.

[0026] In the above scheme, the water outlet pipe is connected to the outside through the vent pipe and the vent hole to achieve internal and external air pressure balance, ensuring that the inner tank and the water outlet pipe can form a communicating vessel, thereby improving the accuracy of the liquid level detection result.

[0027] In a possible design, the liquid heating container also includes a water pump and a connecting pipe. The water pump is installed under the inner tank, the water pump is connected to the water hole, and the connecting pipe is respectively connected to the water pump and the water outlet pipe.

[0028] In the above scheme, the water pump is used to pump the liquid in the inner tank to the water outlet pipe, and the connecting pipe is connected to the water pump and the water outlet pipe respectively, which can improve the sealing of the connection between the water pump and the water outlet pipe and prevent water leakage at the end of the water outlet pipe.

[0029] It should be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0061] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0063] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0064] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0065] The present application embodiment provides a liquid heating container, such as Figure 1 and Figure 2 As shown, the liquid heating container comprises a shell 1, an inner liner 2 installed inside the shell 1, a water outlet pipe 3 and a liquid level detection assembly 4, as well as a container cover 12 snapped onto the shell 1 and a handle 13 installed on the outer wall of the shell 1. The inner liner 2 is used to hold liquid, the shell 1 is provided with a water outlet 11, and the bottom of the inner liner 2 is provided with a water hole 21. The two ends of the water outlet pipe 3 are respectively connected to the water hole 21 and the water outlet 11. Figure 3 As shown, the liquid level detection assembly 4 includes a liquid level sensor 41 , which is attached to the outer wall of the water outlet pipe 3 and is used to detect the liquid level in the water outlet pipe 3 .

[0066] In this embodiment, the water outlet 11 is connected to the outside, and the water outlet pipe 3 connects the inner tank 2 and the water outlet 11. When the user takes water, the cup can be placed under the water outlet 11, and the water in the inner tank 2 can flow into the cup through the water outlet pipe 3 and the water outlet 11. Figure 1As shown, the water outlet pipe 3 is located in the gap between the shell 1 and the inner tank 2. When the user does not take water, the water outlet pipe 3 can form a communicating vessel with the inner tank 2. The liquid level in the water outlet pipe 3 is flush with the liquid level in the inner tank 2. The liquid level sensor 41 is a non-contact sensor, which is arranged on the outer wall of the water outlet pipe 3 and can detect the liquid level in the water outlet pipe 3, thereby determining the liquid level in the inner tank 2. Specifically, when the liquid level in the water outlet pipe 3 exceeds the bottom of the liquid level sensor 41 and when the liquid level in the water outlet pipe 3 is lower than the bottom of the liquid level sensor 41, the signal generated by the liquid level sensor 41 is different. By monitoring the signal of the liquid level sensor 41, the liquid level in the inner tank 2 can be determined. Therefore, the liquid level sensor 41 can be arranged at the bottom of the water outlet pipe 3 to realize the low liquid level detection function of the liquid heating container.

[0067] The liquid heating container provided by the present application can determine whether the liquid level in the inner tank 2 is too low by detecting whether the signal of the liquid level sensor 41 changes. It does not require the user to observe with the naked eye, and the judgment result is more accurate, which makes the user experience better. There is no need to set a transparent window on the shell 1, which can simplify the structure of the shell 1. The water outlet pipe 3 does not need to be provided with a glass tube part, which can also simplify the structure of the water outlet pipe 3 and reduce the risk of water leakage caused by the splicing pipeline. In addition, the transparent window in the prior art needs to be supported by the bracket structure on the shell 1. Due to the limitation of the height of the bracket, in order to see the bottom of the inner tank 2 clearly, the height of the inner tank 2 cannot be set too low, which will cause the volume of the inner tank 2 to be reduced and cause waste of the bottom space of the shell 1. Therefore, the liquid heating container of the present application cancels the transparent window, which is conducive to increasing the depth of the inner tank 2, thereby increasing the volume of the inner tank 2. In addition, in the liquid heating container provided in the present application, the water outlet pipe 3 serves as a water outlet pipe for the liquid when the liquid heating container is discharging water, and also serves as a liquid level detection pipe when the liquid level is detected, thereby achieving the effect of a two-in-one water outlet pipe and a detection pipe. There is no need to set up a liquid level detection pipe separately, which further simplifies the structure of the liquid heating container.

[0068] In a specific embodiment, Figure 3 As shown, the liquid level detection component 4 also includes a detection control board 42, and the liquid level sensor 41 can be electrically connected to the detection control board 42 through a connecting line 43, or can be directly connected to the detection control board signal, which is not limited in this embodiment.

[0069] The detection control board 42 is used to receive the signal sent by the liquid level sensor 41, and judge the liquid level in the inner pot 2 according to the signal, so as to output a signal to control other electrical components in the liquid heating container to turn on or off, so as to realize automatic control of the liquid heating container. Figure 2As shown, a heating plate 9 is provided at the bottom of the inner pot 2, and the heating plate 9 can be electrically connected or signal connected to the detection control board 42. When the detection control board 42 receives a signal that the liquid level is too low, it can control the heating plate 9 to stop heating, thereby preventing dry burning and improving the safety of the liquid heating container.

[0070] In a specific embodiment, Figure 2 As shown, the liquid heating container further includes a display operation component 5 , which includes a display panel 51 and a display control board 52 , and the display panel 51 is electrically connected or signal-connected to the display control board 52 .

[0071] When the user operates on the display panel 51, the display control board 52 can receive signals to control other electrical components in the liquid heating container to turn on or off. For example, the display control board 52 is electrically or signal-connected to the heating disk 9. When the display control board 52 receives the user's operation signal, it can control the heating disk 9 to start or stop heating. The display control board 52 can also be used to control the water discharge from the container, perform liquid level detection, etc.

[0072] like Figure 2 As shown, the display operation component 5 may include a touch spring 53, and the two ends of the touch spring 53 are respectively connected to the buttons on the display panel 51 and the input end of the display control board 52. When the user touches the button, the touch spring 53 can send the corresponding signal to the input end of the display control board 52, and then the output end of the display control board 52 sends a signal to the outside to control the corresponding electrical component to turn on or off.

[0073] Furthermore, if Figure 4 As shown, the display control board 52 is electrically connected or signal-connected to the liquid level sensor, and is electrically connected or signal-connected to the detection control board 42 . The display control board 52 is used to process the detection results of the liquid level sensor 41 and output the processing results to the detection control board 42 .

[0074] When the user takes water, the display control board 52 only receives the signal of the display panel 51 but does not receive the signal of the liquid level sensor 41, or receives the signal of the liquid level sensor 41 but does not process the signal, that is, the display control board 52 can control the liquid heating container not to perform liquid level detection in the water taking state. When the user does not take water, the display control board 52 can be used to receive the signals of the display panel 51 and the liquid level sensor 41. The display control board 52 can process the signal sent by the liquid level sensor 41, and compare it with the preset low liquid level signal reference value, and output the comparison result to the detection control board 42. The detection control board 42 can determine whether the liquid level in the inner tank 2 is lower than the preset height according to the signal output by the display control board 52, and then send instructions to the output module according to the determination result.

[0075] For example, the output module can be a display panel 51, that is, the detection control board 42 can be electrically connected or signal-connected to the display panel 51, and the detection control board 42 can output the judgment result to the display panel 51 for display to prompt the user that the liquid level in the inner tank 2 is too low.

[0076] Alternatively, the output module can be an alarm 6, which is electrically or signal-connected to the detection control board 42. When the detection control board 42 determines that the liquid level is too low, it can send an instruction to the alarm 6 to control the alarm 6 to turn on, and prompt the user through the alarm 6 that the liquid level in the inner tank 2 is too low, and when the detection control board 42 determines that the liquid level is too normal, it can send an instruction to the alarm 6 to control the alarm 6 to turn off.

[0077] Specifically, the alarm 6 can be installed on the display panel 51 to realize the integration of the display panel. The alarm 6 can specifically be a buzzer, an LED light or other parts with prompting functions.

[0078] In the above structure, the detection control board 42 and the display control board 52 can be an integrated structure, that is, the electrical control inside the liquid heating container is realized by a control board with a touch control function. In addition, a power supply 44 is also provided inside the housing 1 for supplying power to the electrical components inside the liquid heating container.

[0079] In a specific embodiment, the liquid level sensor 41 is a copper ring, which acts as a capacitive sensor. When the relative heights of the copper ring and the liquid in the water outlet pipe 3 are different (the liquid level in the water outlet pipe 3 is lower than the bottom of the copper ring or higher than the bottom of the copper ring), different capacitive signals will be generated. The display control board 52 receives the capacitive signal of the copper ring and compares it with the capacitive signal of the preset liquid level. The detection control board 42 makes a judgment based on the comparison result of the capacitive signal. The capacitive sensor has the advantages of high accuracy and high sensitivity in detecting the liquid level, and the copper ring is small in size, which can save the internal space of the liquid heating container, and the copper ring itself has a relatively simple structure, high flexibility, and can adapt to different installation positions.

[0080] Specifically, Figure 4 and Figure 5 As shown, the copper ring can be sleeved outside the water outlet pipe 3, and the inner wall of the copper ring fits with the outer wall of the water outlet pipe 3.

[0081] The copper ring itself is relatively small in size, and when it is sleeved on the outside of the water outlet pipe 3, it can further save space. Moreover, the inner wall of the copper ring fits the water outlet pipe 3, which can improve the installation stability of the copper ring and prevent the copper ring from shifting after the liquid container is shaken, which is beneficial to improving the detection accuracy of the liquid level sensor 41.

[0082] Or, if Figure 6As shown, the copper ring can be fixed on the outer wall of the water outlet pipe 3, and along the axial direction X of the copper ring, one end of the copper ring fits the outer wall of the water outlet pipe 3. The copper ring can be bonded and fixed on the outer wall of the water outlet pipe 3, making the installation of the liquid level sensor 41 more convenient.

[0083] In a specific implementation, the water outlet pipe 3 is made of insulating material.

[0084] In the present application, since water is a conductive liquid, an insulating container must be used when using a capacitive sensor for liquid level detection. Therefore, the water outlet pipe 3 should be made of insulating material, otherwise it will affect the accuracy of liquid level detection.

[0085] In a specific embodiment, the water outlet pipe 3 has a lowest liquid level line, and along the height direction Z of the liquid heating container, the bottom end of the liquid level sensor 41 is flush with the lowest liquid level line in the water outlet pipe 3 .

[0086] In this embodiment, the lowest liquid level line of the water outlet pipe 3 is the lowest liquid level line of the inner tank 2. When the liquid in the water outlet pipe 3 is lower than the lowest liquid level line, the detection capacitance of the liquid level sensor 41 will change, and the detection control board 42 can thereby determine whether the liquid level in the inner tank 2 is too low.

[0087] It should be noted that the minimum liquid level line is not a specific scale line, but indicates that there is a preset minimum liquid level in the water pipe 3. The height of the preset minimum liquid level can be adjusted by adjusting the height position of the liquid level sensor 41 on the outlet pipe 3. Only when the liquid level in the outlet pipe 3 is lower than the liquid level sensor 41, the alarm 6 will sound an alarm under the instruction of the detection control board 42.

[0088] In the above embodiments, Figure 2 As shown, the housing 1 is also provided with a vent hole communicating with the outside, and the vent hole is communicated with the water outlet pipe 3 through a vent pipe 7 .

[0089] The water outlet pipe 3 is connected to the outside through the ventilation pipe 7 and the ventilation hole to achieve internal and external air pressure balance, ensuring that the inner tank 2 and the water outlet pipe 3 can form a communicating vessel, thereby improving the accuracy of the liquid level detection result.

[0090] In a specific embodiment, Figure 2 As shown, the liquid heating container also includes a water pump 8, which is installed under the inner tank 2. The water pump 8 is connected to the water hole 21 and the water outlet pipe 3 respectively. The water pump 8 can be electrically connected or signal connected to the display control panel 52 to control the water pump 8 to pump the liquid in the inner tank 2 to the water outlet pipe 3.

[0091] like Figure 4As shown, the liquid heating container further includes a connecting pipe 81, which is connected to the water pump 8 and the water outlet pipe 3 respectively, and can improve the connection sealing performance between the water pump 8 and the water outlet pipe 3, and prevent water leakage at the end of the water outlet pipe 3. In addition, a step portion 811 is provided on the inner wall of the connecting pipe 81, and the end of the water outlet pipe 3 extends into the connecting pipe 81 and abuts against the step portion 811 along the height direction Z of the liquid heating container. The step portion 811 can limit the water outlet pipe 3, and improve the connection stability between the connecting pipe 81 and the water outlet pipe 3. At the same time, the top of the connecting pipe 81 can also be used to limit the liquid level sensor 41, and improve the installation stability of the liquid level sensor 41.

[0092] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
