Description

Technical Field

[0001] This application relates to the field of household appliances, and more particularly to a liquid heating container. Background Technology

[0002] Liquid heating containers are typically equipped with a temperature sensor, which is usually located inside the container to detect the temperature of the liquid inside. The control board, which is electrically connected to the temperature sensor, can receive the temperature information detected by the temperature sensor and adjust the heating power of the liquid heating container accordingly.

[0003] Because the temperature sensor is located inside the kettle, it cannot sense the temperature of the environment in which the liquid heating container is located, and the ambient temperature affects the heating effect of the liquid heating container. This results in poor temperature control during the heating process of existing liquid heating containers: the control board cannot adjust the heating power according to the ambient temperature. When the ambient temperature is high, the liquid in the kettle may overboil due to excessive heating power; when the ambient temperature is low, the liquid in the kettle may not heat sufficiently due to insufficient heating power, affecting the user experience. Utility Model Content

[0004] This application provides a liquid heating container that can solve the problem of insufficient temperature control capability of liquid heating containers in the prior art.

[0005] This application provides a liquid heating container, comprising: a body for holding liquid; a base for supporting the body; a first temperature sensor mounted on the body for detecting the temperature of the liquid inside the body; a second temperature sensor mounted on the base for detecting the temperature of the environment in which the liquid heating container is located; and a control board mounted on the base, the control board being electrically or signal-connected to the first temperature sensor to receive temperature information from the first temperature sensor; the control board is also electrically or signal-connected to the second temperature sensor to receive temperature information from the second temperature sensor.

[0006] In the above solution, since the ambient temperature of the liquid heating container affects the heating of the liquid inside the pot, if the liquid heating container is only equipped with a first temperature sensor, the influence of the ambient temperature on the heating of the liquid inside the pot cannot be eliminated. The liquid heating container can only adjust its heating state based on the temperature of the liquid inside the pot detected by the first temperature sensor, which will lead to inaccurate temperature regulation: for two liquid heating containers in different ambient temperatures, when the liquid temperatures inside their pots are the same, if the heating state of both is adjusted in the same way, the liquid heating container in the higher ambient temperature may overboil due to excessive heating power; the liquid heating container in the lower ambient temperature may underheat due to insufficient heating power.

[0007] This embodiment of the application reduces the impact of ambient temperature on the heating effect of the liquid heating container by setting a second temperature sensor to detect the ambient temperature. The control board processes the temperature information detected by the first and second temperature sensors and calculates the impact of the current external temperature on the temperature rise of the liquid inside the pot. This allows for targeted adjustment of the heating state of the liquid heating container, ensuring that the liquid and food inside the pot are always at a stable heating temperature, improving the uniformity of heating and increasing the heating efficiency of the liquid heating container. Furthermore, in this embodiment, the second temperature sensor is mounted on the base, away from the pot body, preventing the liquid temperature inside the pot from affecting the sensor's detection results. This improves the accuracy of the second temperature sensor's detection results and thus enhances the temperature control precision of the liquid heating container.

[0008] In one possible design, the liquid heating container further includes a heating element installed on the body of the container for heating the liquid inside the container; the heating element is electrically or signal-connected to the control board, and the control board can adjust the heating power of the heating element according to the temperature information from the first temperature sensor and the temperature information from the second temperature sensor.

[0009] In the above solution, the control board can directly adjust the heating power of the heating element based on the calculation results of data processing, thereby realizing the automatic adjustment of the heating power of the liquid heating container and ensuring that the liquid in the pot is at a stable heating temperature. This improves the user experience.

[0010] In one possible design, the first temperature sensor is a thermistor; and / or, the second temperature sensor is a thermistor.

[0011] In the above scheme, when the first temperature sensor is a thermistor, a change in the liquid temperature inside the container causes a change in the thermistor's resistance, which in turn changes the voltage in the circuit connected to the thermistor. This allows the control board to obtain information about the liquid temperature change based on the voltage change in the circuit. Thermistors offer advantages such as high sensitivity, fast response speed, high detection accuracy, and low cost, which helps improve the accuracy of the temperature detection results from the first temperature sensor and reduce the overall cost of the liquid heating container. When the second temperature sensor is also a thermistor, a change in the ambient temperature around the liquid heating container allows the control board to obtain information about the ambient temperature change based on the voltage change in the circuit. Thermistors again offer advantages such as high sensitivity, fast response speed, high detection accuracy, and low cost, which helps improve the accuracy of the temperature detection results from the second temperature sensor and reduce the overall cost of the liquid heating container. When both the first and second temperature sensors are thermistors, the temperature control effect of the liquid heating container is improved, and the overall cost of the liquid heating container can be further reduced.

[0012] In one possible design, the second temperature sensor is mounted on the control board.

[0013] In the above scheme, the second temperature sensor is directly mounted on the control board. This not only improves the compactness of the internal parts of the base and saves internal space of the base, but also simplifies the circuit structure when the second temperature sensor is connected to the control board.

[0014] In one possible design, the kettle body includes a main body, the heating element is a heating plate, the heating plate includes a plate body and a heating tube, the plate body and the main body form a receiving cavity, the receiving cavity is used to hold liquid; the heating tube is fixed to the outer bottom wall of the plate body.

[0015] In the above design, the main body and the plate form a cavity for holding liquid, with the plate acting as the bottom wall of the cavity, which simplifies the overall structure of the kettle. The heating element is fixed to the outer bottom wall of the plate, and the heat from the heating element is transferred to the cavity through the plate to achieve the heating function of the heating plate.

[0016] In one possible design, the kettle body further includes a support and an elastic element, the elastic element being mounted on the support, the support being mounted on the outer bottom wall of the saucer body; the first temperature sensor is mounted on the elastic element along the axial direction of the kettle body, and at least a portion of the first temperature sensor is clamped between the elastic element and the outer bottom wall of the saucer body.

[0017] In the above scheme, at least a portion of the first temperature sensor is clamped between the elastic element and the outer bottom wall of the disk. The disk is used to conduct the temperature of the liquid in the containment cavity to the first temperature sensor, so that the first temperature sensor can obtain the temperature information of the liquid in the containment cavity. The first temperature sensor can maintain a tight fit with the outer bottom wall of the disk under the elastic force of the elastic element, which is beneficial to improving the accuracy of the detection results of the first temperature sensor.

[0018] In one possible design, the kettle body further includes a housing mounted on the plate body, with at least a portion of the housing extending into the receiving cavity; the first temperature sensor is mounted inside the housing.

[0019] In the above scheme, the outer shell is used to transmit the temperature of the liquid inside the containment cavity to the first temperature sensor so that the first temperature sensor can obtain the temperature information of the liquid inside the containment cavity.

[0020] In one possible design, the kettle body further includes a sealing ring, and the outer shell is provided with a limiting part located within the receiving cavity; along the axial direction of the kettle body, the sealing ring is clamped between the limiting part and the inner bottom wall of the plate.

[0021] In the above solution, the sealing ring is clamped between the limiting part and the inner bottom wall of the plate to improve the sealing effect between the outer shell and the plate, and prevent the liquid in the receiving cavity from flowing into the space enclosed by the plate and the bottom cover through the gap between the plate and the outer shell, thereby reducing the risk of short circuit of the electrical components inside the kettle.

[0022] In one possible design, the kettle body is provided with a first connector, and the first temperature sensor is electrically connected to the first connector; the base is provided with a second connector, and the control board is electrically connected to the second connector via a connecting line; the first connector and the second connector are plugged into each other to enable the first temperature sensor to be electrically connected to the control board.

[0023] In the above solution, the conductive connection structure between the first connector and the second connector replaces a portion of the conductive wires, which simplifies the circuit structure when connecting the first temperature sensor and the control board. It also avoids exposing conductive wires between the kettle body and the base, reducing the risk of leakage in the liquid heating container and improving the safety of the liquid heating container.

[0024] In one possible design, when the first connector and the second connector are plugged in, the projection of the heating element on the axial direction of the kettle body does not coincide with the projection of the second temperature sensor on the axial direction of the kettle body.

[0025] In the above scheme, the projection of the second temperature sensor does not coincide with that of the heating element, that is, the second temperature sensor is located outside the projection area of ​​the heating element, so that the second temperature sensor can be as far away from the heat source as possible, avoiding the heat of the heating element from affecting the second temperature sensor's detection result of the ambient temperature, which is beneficial to improving the accuracy of the temperature detection result of the second temperature sensor.

[0057] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0058] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0059] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0060] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0061] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0062] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0063] This application provides a liquid heating container, such as... Figure 1 As shown, the liquid heating container includes a body 1 and a base 2. The body 1 is used to hold liquid and food ingredients, and the base 2 is used to support the body 1 and also to form an electrical connection with the body 1, thereby supplying power to the electrical components inside the body 1. The liquid heating container also includes a heating element installed inside the body 1, which is used to heat the liquid inside the body 1. Figure 2 and Figure 3 As shown, the liquid heating container also includes a first temperature sensor 3, a second temperature sensor 4, and a control board 5. The first temperature sensor is installed on the body 1 to detect the temperature of the liquid inside the body 1. The second temperature sensor 4 is installed on the base 2 to detect the temperature of the environment in which the liquid heating container is located. Specifically, the bottom of the base 2 is provided with a vent hole communicating with the outside. The second temperature sensor 4 can obtain the temperature of the environment in which the liquid heating container is located by detecting the temperature of the air entering the base 2 through the vent hole. The control board 5 is installed on the base 2 and is electrically or signal-connected to the first temperature sensor 3 and the second temperature sensor 4, respectively, to receive the temperature information detected by the first temperature sensor 3 and the second temperature sensor 4.

[0064] Because the ambient temperature of the liquid heating container affects the heating of the liquid inside the pot 1 (with the heating element power remaining constant, the liquid inside the pot 1 heats up faster when the ambient temperature is high and slower when the ambient temperature is low), if the liquid heating container only has a first temperature sensor 3, the influence of the ambient temperature on the heating of the liquid inside the pot 1 cannot be eliminated. The liquid heating container can only adjust the power of the heating element based on the temperature of the liquid inside the pot 1 detected by the first temperature sensor 3, which will lead to inaccurate temperature regulation: for two liquid heating containers in different ambient temperatures, when the liquid temperature inside their pots 1 is the same, if the power of their heating elements is adjusted in the same way, the liquid heating container in the higher ambient temperature may overboil due to excessive heating power; the liquid heating container in the lower ambient temperature may underheat due to insufficient heating power.

[0065] This embodiment of the application reduces the impact of ambient temperature on the heating effect of the liquid heating container by setting a second temperature sensor 4 to detect the ambient temperature. The control board 5 can process the temperature information detected by the first temperature sensor 3 and the second temperature sensor 4, and calculate the impact of the current ambient temperature on the temperature rise of the liquid inside the pot 1 based on this temperature information. This allows for targeted adjustment of the heating power of the heating element, ensuring that the liquid and food inside the pot 1 are always at a stable heating temperature, improving the heating uniformity of the liquid and food, and also increasing the heating efficiency of the liquid heating container. Moreover, in this embodiment, the second temperature sensor 4 is set on the base 2, away from the heating element in the pot 1, avoiding the influence of the heating element and the liquid temperature inside the pot 1 on the detection results of the second temperature sensor 4. This helps to improve the accuracy of the detection results of the second temperature sensor 4, thereby improving the temperature control precision of the liquid heating container.

[0066] In one specific embodiment, the control board 5 can send the calculation results of the data processing to the display panel of the liquid heating container, which is then displayed to the user. The user can then manually adjust the heating temperature or heating mode of the liquid heating container based on the prompts from the control board 5. Alternatively, in another specific embodiment, the control board 5 can be signal-connected or electrically connected to the heating element. That is, the control board 5 can directly adjust the heating power of the heating element based on the calculation results of the data processing, thereby achieving automatic adjustment of the heating power of the liquid heating container and improving the user experience.

[0067] The following table shows the cooling of the liquid inside the vessel 1 after boiling in the liquid heating container provided in this application embodiment at an ambient temperature of 24.4℃ and at an ambient temperature of -5℃. In each experimental group, the vessel 1 contained 1.5L of water (specific heat capacity of 4187.5 J / (kg·℃)) and 100g of mung beans.

[0068] Table 1

[0069]

[0070]

[0071] Taking the data from experimental groups 3 and 8 in Table 1 as examples, when the ambient temperature is 24.4℃, it takes 364 seconds for the water in kettle 1 to cool from 95℃ to 90℃. To restore the water to 95℃, the heating power of the heating element needs to be increased by 86.28090659W. However, when the ambient temperature is -5℃, it only takes 203 seconds for the water in kettle 1 to cool from 95℃ to 90℃. This means that, under the same temperature change, the lower the ambient temperature, the greater the heat loss of the liquid heating container. Correspondingly, to restore the water to 95℃, the heating power of the heating element needs to be increased by 154.7105911W. Therefore, it can be seen that the amount of heat required to heat the liquid in kettle 1 to a specified temperature varies greatly depending on the ambient temperature. Therefore, a second temperature sensor 4 is installed on the base to obtain the temperature of the environment where the liquid heating container is located. This allows the control board 5 to comprehensively determine the energy required for the liquid to be heated to the specified temperature based on the ambient temperature and the liquid temperature inside the pot 1. This enables more precise adjustment of the compensation power of the heating element, ensuring that the liquid inside the pot 1 is at a stable heating temperature.

[0072] In one specific embodiment, the heating element can be a boiler or a heating plate. This application uses a heating plate 12 as an example to describe the specific structure of the kettle body 1 in detail. Figure 2 As shown, the kettle body 1 includes a fixedly connected main body 11 and a bottom cover 13, with a heating plate 12 disposed between the main body 11 and the bottom cover 13. The heating plate 12 includes a plate body 121 and a heating tube 122. The plate body 121 is welded or glued to the bottom end of the main body 11 so that the main body 11 and the plate body 121 can form a receiving cavity 10 for holding liquid, that is, the plate body 121 fills the bottom wall of the receiving cavity 10, which helps to simplify the overall structure of the kettle body 1. The heating tube 122 is fixed to the outer bottom wall of the plate body 121, and the heat from the heating tube 122 is transferred to the receiving cavity 10 through the plate body 121 to realize the heating function of the heating plate 12. Specifically, the structure of the heating tube 122 can be C-shaped, U-shaped, annular, or S-shaped to increase the contact area between the plate body 121 and the heating tube 122, thereby improving the heating effect of the heating plate 12.

[0073] In one specific implementation, such as Figure 3 and Figure 4As shown, the kettle body 1 is provided with a first connector 18, and the base 2 is provided with a second connector 21. When the kettle body 1 is placed on the base 2, the first connector 18 and the second connector 21 can be plugged in to achieve electrical connection, so that the base 2 can supply power to the heating plate 12 and other electrical components inside the kettle body 1. In this embodiment, the first temperature sensor 3 is electrically connected to the control board 5. Specifically, the first temperature sensor 3 is electrically connected to the first connector 18 through a conductive wire (not shown in the figure), and the second connector 21 is electrically connected to the input port on the control board 5 through a connecting wire 6, so that the first temperature sensor 3 can achieve electrical connection with the control board 5 when the first connector 18 and the second connector 21 are plugged in. That is, this embodiment replaces a portion of the conductive wire with the conductive connection structure of the first connector 18 and the second connector 21, which simplifies the circuit structure when the first temperature sensor 3 is connected to the control board 5, and avoids the presence of exposed conductive wires between the kettle body 1 and the base 2, reducing the risk of leakage of the liquid heating container and improving the safety of the liquid heating container.

[0074] In one specific embodiment, the first temperature sensor 3 can be a thermistor. When the temperature of the liquid inside the vessel 1 changes, the resistance of the thermistor changes accordingly, thereby changing the voltage in the circuit connected to the thermistor. This allows the control board 5 to obtain the temperature change of the liquid inside the vessel 1 based on the voltage change in the circuit. Thermistors have advantages such as high sensitivity, fast response speed, high detection accuracy, and low cost, which helps to improve the accuracy of the temperature detection results of the first temperature sensor 3 and reduce the overall cost of the liquid heating container.

[0075] Specifically, the first temperature sensor 3 can detect the liquid temperature inside the vessel 1 using either a contact or non-contact method. In this embodiment, the installation structure of the first temperature sensor 3 is described in detail using a non-contact detection method.

[0076] In one specific embodiment, the first temperature sensor 3 can be disposed outside the receiving cavity 10, such as... Figure 2 , Figure 4 and Figure 5As shown, the kettle body 1 also includes a bracket 14 and an elastic element 15. The bracket 14 is fixedly connected to the outer bottom wall of the disc body 121 by a fastener 19. The elastic element 15 is mounted on the bracket 14, and the first temperature sensor 3 is mounted on the elastic element 15. Along the axial direction Z of the kettle body 1, at least a portion of the first temperature sensor 3 is clamped between the elastic element 15 and the outer bottom wall of the disc body 121. The disc body 121 is used to conduct the temperature of the liquid in the receiving cavity 10 to the first temperature sensor 3, so that the first temperature sensor 3 can obtain the temperature information of the liquid in the receiving cavity 10. The first temperature sensor 3 can maintain a tight fit with the outer bottom wall of the disc body 121 under the elastic force of the elastic element 15, which helps to improve the accuracy of the detection results of the first temperature sensor 3.

[0077] like Figure 2 and Figure 5 As shown, the elastic member 15 has a mounting groove 151 at one end facing the disc body 121. At least a part of the first temperature sensor 3 is located in the mounting groove 151. The mounting groove 151 can limit the installation of the first temperature sensor 3, which helps to improve the installation reliability of the first temperature sensor 3.

[0078] Alternatively, in another embodiment, the first temperature sensor 3 can extend into the receiving cavity 10, such as... Figure 6 As shown, the vessel body 1 also includes a shell 16, which is fixedly installed on the plate body 121, and at least a portion of the shell 16 extends into the receiving cavity 10. A first temperature sensor 3 is installed inside the shell 16. That is, the shell 16 is used to conduct the temperature of the liquid in the receiving cavity 10 to the first temperature sensor 3, so that the first temperature sensor 3 can obtain the temperature information of the liquid in the receiving cavity 10. The shell 16 can be made of metal, and the first temperature sensor 3 is tightly fitted to the inner top or bottom wall of the shell 16 to improve the heat conduction effect of the shell 16, which is beneficial to improving the accuracy of the detection results of the first temperature sensor 3.

[0079] like Figure 6 As shown, the kettle body 1 also includes a sealing ring 17, and the outer shell 16 is provided with a limiting part 161. The limiting part 161 has an annular protruding structure and is located inside the receiving cavity 10 to prevent the outer shell 16 from falling off the plate 121. Along the axial direction Z of the kettle body 1, the sealing ring 17 is clamped between the limiting part 161 and the inner bottom wall of the plate 121 to improve the sealing effect between the outer shell 16 and the plate 121, and prevent the liquid in the receiving cavity 10 from flowing into the space enclosed by the plate 121 and the bottom cover 13 through the gap between the plate 121 and the outer shell 16, thereby reducing the risk of short circuit of the electrical components inside the kettle body 1.

[0080] The limiting part 161 can be provided with a limiting groove 161a on the side facing the disc body 121. The sealing ring 17 can be installed in the limiting groove 161a. The limiting groove 161a can prevent the sealing ring 17 from shifting, thereby improving the installation stability of the sealing ring 17 and ensuring the sealing effect between the outer shell 16 and the disc body 121.

[0081] In one specific embodiment, the second temperature sensor 4 can be a thermistor. When the ambient temperature of the liquid heating container changes, the resistance of the thermistor changes accordingly, thereby changing the voltage in the circuit connected to the thermistor. This allows the control board 5 to obtain information about the change in ambient temperature based on the voltage change in the circuit. Thermistors have advantages such as high sensitivity, fast response speed, high detection accuracy, and low cost, which helps to improve the accuracy of the temperature detection results of the second temperature sensor 4 and reduce the overall cost of the liquid heating container.

[0082] In the above embodiments, when the kettle body 1 is placed on the base 2, or when the first connector 18 and the second connector 21 are plugged in, the projection of the heating element on the axial direction Z of the kettle body 1 does not coincide with the projection of the second temperature sensor 4 on the axial direction Z of the kettle body 1. That is, the second temperature sensor is located outside the projection area of ​​the heating element, so that the second temperature sensor 4 can be as far away from the heat source as possible, avoiding the heat of the heating element from affecting the detection result of the second temperature sensor 4 of the ambient temperature, which is beneficial to improving the accuracy of the temperature detection result of the second temperature sensor 4.

[0083] Specifically, the second temperature sensor 4 can be installed outside the control board 5 and electrically connected to the control board 5 via a conductive wire. Or, as... Figure 3 As shown, the second temperature sensor 4 can also be directly mounted on the control board 5. This not only improves the compactness of the internal parts of the base 2 and saves the internal space of the base, but also simplifies the circuit structure when the second temperature sensor 4 is connected to the control board 5.

[0084] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
