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] With the increase in people's demand for use and the development direction of product automation, many liquid heating containers on the market have the function of automatic water addition, which can automatically replenish the liquid in the container when it is insufficient. In the prior art, in order to realize the automatic water addition function, a water level detection device needs to be installed in the kettle body, and whether water needs to be added is determined according to the result of the water level detection device. However, the existing water level detection device still has the problem of insufficient reliability. Utility Model Content

[0003] The present application provides a liquid heating container, which can improve the reliability of water level detection results in the liquid heating container.

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

[0005] Circuit boards;

[0006] The inner tank is used to hold liquid;

[0007] A first conductive member, mounted on the inner container, wherein at least a portion of the first conductive member extends out of the inner container and is electrically connected to the circuit board;

[0008] A second conductive member is installed in the inner container, and at least a portion of the second conductive member extends out of the inner container and is electrically connected to the circuit board.

[0009] In the above scheme, since the liquid is conductive, the first conductive member and the second conductive member can form a passage through the liquid in the inner tank. When the liquid in the inner tank contacts the first conductive member and the second conductive member at the same time, a closed circuit can be formed between the first conductive member, the second conductive member and the circuit board; when the liquid in the inner tank cannot contact the first conductive member and the second conductive member at the same time, an open circuit is formed between the first conductive member, the second conductive member and the circuit board. That is, the first conductive member, the second conductive member and the circuit board form a water level detection circuit. The control device (such as a single-chip microcomputer) on the circuit board can determine whether there is liquid in the inner tank according to the connectivity of the circuit, and conveniently control the water injection device to add liquid to the inner tank when there is no liquid, thereby realizing the automatic water filling function of the liquid heating container.

[0010] The liquid heating container provided in the present application can realize the water level detection function by only setting two conductive components electrically connected to the circuit board, thereby simplifying the structure of the water level detection device. Moreover, compared with the method of setting a liquid level sensor, the first conductive component and the second conductive component are not affected by the water temperature and impurities in the liquid, and the possibility of failure is lower, which can improve the reliability of the water level detection results.

[0011] In a possible design, the liquid heating container also includes a thermistor; the thermistor is electrically connected or signal-connected to the circuit board; the first conductive member is a metal shell with an inner cavity, and the thermistor is installed in the inner cavity.

[0012] In the above scheme, the thermistor is used to detect the temperature of the liquid in the inner tank. When the temperature is too high, the thermistor can send a signal to the circuit board to prevent dry burning and improve the safety of the liquid heating container. The first conductive member is a metal shell with an inner cavity, and the thermistor is installed in the inner cavity, that is, the thermistor and the first conductive member together constitute a temperature detection device. The thermistor indirectly detects the temperature of the liquid in the inner tank through the metal shell, and there is no need to set up an additional metal shell for the thermistor, thereby achieving the effect of simplifying parts and saving internal space of the liquid heating container.

[0013] In a possible design, the second conductive member is a metal shell with an inner cavity, or the second conductive member is a solid conductive column.

[0014] In the above solution, the second conductive member is a metal shell with an inner cavity, and the second conductive member can have the same structure as the first conductive member, that is, existing parts can be used as the second conductive member, which is conducive to reducing the cost of the liquid heating container. Alternatively, the second conductive member can also be a solid conductive column to appropriately reduce the volume of the second conductive member.

[0015] In a possible design, the liquid heating container also includes a first insulating sleeve; the first conductive member includes a first main body and a first probe; the first insulating sleeve is installed on the first main body to insulate and isolate the first main body from the inner tank.

[0016] In the above scheme, the first body is used to be electrically connected to the circuit board. When the inner tank is made of metal, a first insulating sleeve is required to ensure that the first body is insulated from the inner tank to avoid forming a path between the first conductive member and the inner tank, thereby preventing the normal operation of the water level detection function from being affected. The first probe is exposed from the first insulating sleeve and is used to contact the liquid in the inner tank so as to form a path between the first conductive member and the second conductive member.

[0017] In a possible design, the liquid heating container also includes a second insulating sleeve; the second conductive member includes a second body and a second probe; the second insulating sleeve is installed on the second body to insulate the second body from the inner tank.

[0018] In the above scheme, the second body is used to be electrically connected to the circuit board. When the inner tank is made of metal, a second insulating sleeve is required to ensure that the second body is insulated from the inner tank to avoid forming a path between the second conductive member and the inner tank, thereby preventing the normal operation of the water level detection function from being affected. The second probe is exposed from the second insulating sleeve and is used to contact the liquid in the inner tank so as to form a path between the first conductive member and the second conductive member.

[0019] In one possible design, along the axial direction of the first conductive member, at least a portion of the first insulating sleeve is clamped between the first probe and the inner liner; and / or, along the axial direction of the second conductive member, at least a portion of the second insulating sleeve is clamped between the second probe and the inner liner.

[0020] In the above solution, the first probe and the inner liner jointly clamp the first insulating sleeve, which can limit the first insulating sleeve and prevent the first insulating sleeve from falling off from the first body, thereby improving the installation stability of the first insulating sleeve. Similarly, the second probe and the inner liner jointly clamp the second insulating sleeve, which can limit the second insulating sleeve and prevent the second insulating sleeve from falling off from the second body, thereby improving the installation stability of the second insulating sleeve.

[0021] In a possible design, the first conductive member and the second conductive member are both installed at the bottom of the inner liner; the height difference between the top of the first insulating sleeve and the bottom wall of the inner liner is H1, H1≥4mm; and / or the height difference between the top of the second insulating sleeve and the bottom wall of the inner liner is H2, H2≥4mm.

[0022] In the above scheme, when the height difference H1 between the top of the first insulating sleeve and the bottom wall of the inner container is greater than or equal to 4 mm, the use safety of the liquid heating container can be improved, the service life of the liquid heating container can be extended, and the insulation effect of the first insulating sleeve can be ensured not to be affected. Similarly, when the height difference H2 between the top of the second insulating sleeve and the bottom wall of the inner container is greater than or equal to 4 mm, the use safety of the liquid heating container can be improved, the service life of the liquid heating container can be extended, and the insulation effect of the second insulating sleeve can be ensured not to be affected.

[0023] In a possible design, the liquid heating container further includes a heating plate, which is mounted on the outer surface of the bottom wall of the inner tank; the heating plate is electrically connected or signal-connected to the circuit board.

[0024] In the above scheme, the heating plate is used to heat the liquid in the inner tank. The heating plate is electrically connected or signal-connected to the circuit board, so that the circuit board can control the working state of the heating plate, thereby realizing the temperature control function of the liquid heating container.

[0025] In a possible design, both the first body and the second body pass through the heating plate; the first insulating sleeve is used to insulate and isolate the first body from the heating plate, and the second insulating sleeve is used to insulate and isolate the second body from the heating plate.

[0026] In the above solution, the outer shell of the heating plate is made of metal, and the first insulating sleeve can insulate and isolate the first body from the heating plate to avoid the formation of a passage between the first conductive member and the heating plate, thereby preventing the normal operation of the water level detection function from being affected. Similarly, the second insulating sleeve can insulate and isolate the second body from the heating plate to avoid the formation of a passage between the second conductive member and the heating plate, thereby preventing the normal operation of the water level detection function from being affected.

[0027] In one possible design, the first insulating sleeve is provided with a first groove, and at least a portion of the bottom wall of the inner liner and at least a portion of the heating plate are accommodated in the first groove; and / or, the second insulating sleeve is provided with a second groove, and at least a portion of the bottom wall of the inner liner and at least a portion of the heating plate are accommodated in the second groove.

[0028] In the above scheme, when at least part of the bottom wall of the inner tank and at least part of the heating plate are accommodated in the first groove, the installation stability of the first insulating sleeve, the inner tank and the heating plate can be improved, and at the same time, the first insulating sleeve can ensure that the first conductive member forms a sealed fit with the inner tank and the heating plate to prevent the liquid in the inner tank from leaking out. Similarly, when at least part of the bottom wall of the inner tank and at least part of the heating plate are accommodated in the second groove, the installation stability of the second insulating sleeve, the inner tank and the heating plate can be improved, and at the same time, the second insulating sleeve can ensure that the second conductive member forms a sealed fit with the inner tank and the heating plate to prevent the liquid in the inner tank from leaking out.

[0053] 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.

[0054] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0055] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0056] 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.

[0057] 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.

[0058] The present application embodiment provides a liquid heating container, such as Figure 1 As shown, the liquid heating container comprises a pot body 10 and a bottom cover 20 connected to each other, and the pot body 10 and the bottom cover 20 form a receiving cavity. Figure 2 As shown, the liquid heating container includes a circuit board 1, an inner pot 2, a first conductive member 3 and a second conductive member 4. The circuit board 1 and the inner pot 2 are both installed in the accommodating cavity. The inner pot 2 is used to hold liquid. The first conductive member 3 is installed in the inner pot 2, and at least a portion of the first conductive member 3 extends out of the inner pot 2 and is electrically connected to the circuit board 1. The second conductive member 4 is installed in the inner pot 2, and at least a portion of the second conductive member 4 extends out of the inner pot 2 and is electrically connected to the circuit board 1.

[0059] In this embodiment, since the liquid is conductive, the first conductive member 3 and the second conductive member 4 can form a passage through the liquid in the inner container 2, such as Figure 3 As shown, when the liquid in the inner tank 2 contacts the first conductive member 3 and the second conductive member 4 at the same time, a closed loop can be formed between the first conductive member 3, the second conductive member 4 and the circuit board 1; Figure 2As shown, when the liquid in the inner pot 2 cannot contact the first conductive member 3 and the second conductive member 4 at the same time, a circuit is broken between the first conductive member 3, the second conductive member 4 and the circuit board 1. That is, the first conductive member 3, the second conductive member 4 and the circuit board 1 form a water level detection circuit, and the control device (such as a single chip microcomputer) on the circuit board 1 can determine whether there is liquid in the inner pot 2 according to the connectivity of the circuit, and conveniently control the water injection device to add liquid to the inner pot 2 when there is no liquid, thereby realizing the automatic water filling function of the liquid heating container.

[0060] Specifically, for example Figure 2 As shown, the first conductive member 3 is connected to the DC ground of the circuit board 1. When the first conductive member 3, the second conductive member 4 and the circuit board 1 form a path, the control device on the circuit board 1 can receive a grounding signal, based on which it can be determined that there is water in the inner tank 2; when the first conductive member 3, the second conductive member 4 and the circuit board 1 form an open circuit, the control device on the circuit board 1 cannot receive a signal, based on which it can be determined that there is no water in the inner tank 2.

[0061] The liquid heating container provided in the present application can realize the water level detection function by only setting two conductive components electrically connected to the circuit board 1, thereby simplifying the structure of the water level detection device. Moreover, compared with the method of setting a liquid level sensor, the first conductive component 3 and the second conductive component 4 are not affected by the water temperature and impurities in the liquid, and the possibility of failure is lower, which can improve the reliability of the water level detection result.

[0062] In a specific embodiment, Figure 2 As shown, the liquid heating container further includes a heating plate 8 for heating the liquid in the inner pot 2. The heating plate 8 is electrically connected or signal-connected to the circuit board 1, so that the control device in the circuit board 1 can control the working state of the heating plate 8, thereby realizing the temperature control function of the liquid heating container.

[0063] In addition, if Figure 2 As shown, the liquid heating container also includes a thermistor 5, which is electrically connected or signal-connected to the circuit board 1. The thermistor 5 is used to detect the temperature of the liquid in the inner pot 2. When the temperature is too high, the thermistor 5 can send a signal to the circuit board 1. After receiving the signal, the control device of the circuit board 1 can issue an alarm to remind the user, or the control device can directly control the heating plate 8 to stop heating, that is, the thermistor 5 can play a role in preventing dry burning, thereby improving the safety of the liquid heating container.

[0064] like Figure 4As shown, the first conductive member 3 is a metal shell with an inner cavity, and the thermistor 5 is installed in the inner cavity, that is, the thermistor 5 and the first conductive member 3 together constitute a temperature detection device, and the thermistor 5 indirectly detects the temperature of the liquid in the inner tank 2 through the metal shell, and there is no need to set an additional metal shell for the thermistor 5, which achieves the effect of simplifying parts and saving the internal space of the liquid heating container, and at the same time can reduce the cost of the liquid heating container. In other words, this embodiment directly uses the metal shell of the thermistor 5 as the first conductive member 3, so that the metal shell has the dual functions of measuring temperature and measuring water level.

[0065] In a specific embodiment, Figure 2 As shown, the second conductive member 4 is a metal shell with an inner cavity. The second conductive member 4 can have the same structure as the first conductive member 3, that is, existing components can be used as the second conductive member 4, which is beneficial to reducing the cost of the liquid heating container.

[0066] Alternatively, the second conductive member 4 may be a solid conductive column to appropriately reduce the volume of the second conductive member 4. This embodiment does not limit the material of the conductive column, as long as the material has good conductivity, is non-toxic and harmless, and does not affect the normal operation of the liquid heating container.

[0067] In a specific embodiment, Figure 4 As shown, the liquid heating container further includes a first insulating sleeve 6, the first conductive member 3 includes a first main body 31 and a first probe 32, the first insulating sleeve 6 is mounted on the first main body 31, and is used to insulate the first main body 31 from the inner pot 2. The liquid heating container further includes a second insulating sleeve 7, the second conductive member 4 includes a second main body 41 and a second probe 42, the second insulating sleeve 7 is mounted on the second main body 41, and is used to insulate the second main body 41 from the inner pot 2.

[0068] Please combine Figure 3 For reference, the first main body 31 is used to be electrically connected to the circuit board 1. When the inner tank 2 is made of metal, a first insulating sleeve 6 needs to be provided to ensure that the first main body 31 is insulated and isolated from the inner tank 2 to avoid formation of a path between the first conductive member 3 and the inner tank 2, thereby preventing the normal operation of the water level detection function from being affected and also preventing leakage of the inner tank 2.

[0069] Similarly, please combine Figure 3 For reference, the second main body 41 is used to be electrically connected to the circuit board 1. When the inner tank 2 is made of metal, a second insulating sleeve 7 needs to be provided to ensure that the second main body 41 is insulated and isolated from the inner tank 2 to avoid the formation of a passage between the second conductive member 4 and the inner tank 2, thereby preventing the normal operation of the water level detection function from being affected and also preventing the inner tank 2 from leaking electricity.

[0070] The first probe 32 is exposed from the first insulating sleeve 6 , and the second probe 42 is exposed from the second insulating sleeve 7 . The first probe 32 and the second probe 42 are respectively used to contact the liquid in the inner tank 2 , so as to form a passage between the first conductive member 3 and the second conductive member 4 .

[0071] In a specific embodiment, the first conductive member 3 and the second conductive member 4 are both installed at the bottom of the inner liner 2, and the height difference between the top of the first insulating sleeve 6 and the bottom wall of the inner liner 2 is H1, H1 ≥ 4mm, and / or, the height difference between the top of the second insulating sleeve 7 and the bottom wall of the inner liner 2 is H2, H2 ≥ 4mm. Specifically, H1 can be 4mm, 4.2mm, 4.5mm, 4.8mm, 5mm, 5.5mm, 6mm or 7mm, or other values ​​within the above range, which is not limited in this embodiment. H2 can be 4mm, 4.2mm, 4.5mm, 4.8mm, 5mm, 5.5mm, 6mm or 7mm, or other values ​​within the above range, which is not limited in this embodiment. H1 and H2 can be equal or unequal.

[0072] In this embodiment, when one of H1 and H2 is less than 4mm, it means that the first conductive member 3 and the second conductive member 4 will be disconnected only when the liquid level in the inner tank 2 is lower than 4mm, that is, only when the liquid is lower than 4mm will the control device of the circuit board 1 receive a signal to determine that there is no water in the inner tank 2. However, too low a liquid level can easily cause the liquid heating container to dry-burn, affecting the safety of the liquid heating container and reducing the service life of the liquid heating container. At the same time, when H1 is less than 4mm, the creepage distance of the first probe 32 will be insufficient, thereby affecting the insulation effect of the first insulating sleeve 6; when H2 is less than 4mm, the creepage distance of the second probe 42 will be insufficient, thereby affecting the insulation effect of the second insulating sleeve 7.

[0073] Therefore, when the height difference H1 between the top of the first insulating sleeve 6 and the bottom wall of the inner container 2 is greater than or equal to 4 mm, the use safety of the liquid heating container can be improved, the service life of the liquid heating container can be extended, and the insulation effect of the first insulating sleeve 6 can be ensured not to be affected. Similarly, when the height difference H2 between the top of the second insulating sleeve 7 and the bottom wall of the inner container 2 is greater than or equal to 4 mm, the use safety of the liquid heating container can be improved, the service life of the liquid heating container can be extended, and the insulation effect of the second insulating sleeve 7 can be ensured not to be affected.

[0074] It should be noted that since the first insulating sleeve 6 has a certain thickness and has a certain heat-insulating effect, in order to ensure the temperature measurement accuracy of the thermistor 5, the thermistor 5 is preferably arranged in the inner cavity of the first probe 32, and preferably close to the side wall of the inner cavity to improve the temperature measurement precision and accuracy, so as to facilitate timely sending of signals to the circuit board 1 when the liquid in the inner tank 2 is too high.

[0075] In a specific embodiment, Figure 2 As shown, along the axial direction Z of the first conductive member 3, at least part of the first insulating sleeve 6 is clamped between the first probe 32 and the inner tank 2, and / or, as shown in FIG. Figure 3 As shown, along the axial direction Z of the second conductive member 4 , at least a portion of the second insulating sleeve 7 is clamped between the second probe 42 and the inner container 2 .

[0076] In this embodiment, the first probe 32 and the inner liner 2 jointly clamp the first insulating sleeve 6, which can limit the first insulating sleeve 6, prevent the first insulating sleeve 6 from falling off from the first body 31, and improve the installation stability of the first insulating sleeve 6. Similarly, the second probe 42 and the inner liner 2 jointly clamp the second insulating sleeve 7, which can limit the second insulating sleeve 7, prevent the second insulating sleeve 7 from falling off from the second body 41, and improve the installation stability of the second insulating sleeve 7.

[0077] In a specific embodiment, Figure 3 As shown, the heating plate 8 is installed on the outer surface of the bottom wall of the inner tank 2, the first main body 31 and the second main body 41 both pass through the heating plate 8, the first insulating sleeve 6 is used to insulate and isolate the first main body 31 from the heating plate 8, and the second insulating sleeve 7 is used to insulate and isolate the second main body 41 from the heating plate 8.

[0078] In this embodiment, the heating plate 8 is provided with two through holes, which are convenient for the first body 31 and the second body 41 to pass through. The outer shell of the heating plate 8 is made of metal, and the first insulating sleeve 6 can insulate and isolate the first body 31 from the heating plate 8 to avoid the formation of a passage between the first conductive member 3 and the heating plate 8, thereby preventing the normal operation of the water level detection function from being affected. Similarly, the second insulating sleeve 7 can insulate and isolate the second body 41 from the heating plate 8 to avoid the formation of a passage between the second conductive member 4 and the heating plate 8, thereby preventing the normal operation of the water level detection function from being affected.

[0079] Specifically, Figure 4 As shown, the first insulating sleeve 6 is provided with a first groove 61, and at least part of the bottom wall of the inner tank 2 and at least part of the heating plate 8 are accommodated in the first groove 61; and / or, as shown Figure 5 As shown, the second insulating sleeve 7 is provided with a second groove 71 , and at least a portion of the bottom wall of the inner tank 2 and at least a portion of the heating plate 8 are accommodated in the second groove 71 .

[0080] Please combine Figure 2As shown, when at least part of the bottom wall of the inner liner 2 and at least part of the heating plate 8 are accommodated in the first groove 61, the installation stability of the first insulating sleeve 6, the inner liner 2 and the heating plate 8 can be improved. At the same time, the first insulating sleeve 6 can ensure that the first conductive member 3 forms a sealed fit with the inner liner 2 and the heating plate 8 to prevent the liquid in the inner liner 2 from leaking out. Similarly, when at least part of the bottom wall of the inner liner 2 and at least part of the heating plate 8 are accommodated in the second groove 71, the installation stability of the second insulating sleeve 7, the inner liner 2 and the heating plate 8 can be improved. At the same time, the second insulating sleeve 7 can ensure that the second conductive member 4 forms a sealed fit with the inner liner 2 and the heating plate 8 to prevent the liquid in the inner liner 2 from leaking out.
