Description

Technical Field

[0001] This utility model relates to the field of small household appliance technology, and in particular to an electric kettle with adjustable temperature via sliding mechanism. Background Technology

[0002] Electric kettles are common household appliances. Existing electric kettles mainly consist of two parts: the kettle itself and the base. A heating element is located at the bottom of the kettle to heat the water when electricity is applied. Traditional electric kettles only have temperature measurement and display functions and cannot adjust the temperature. However, with the improvement of people's living standards, various teas and brewed beverages have gained popularity. These beverages have specific water temperature requirements, thus, electric kettles with adjustable temperature have emerged.

[0003] Existing adjustable temperature electric kettles generally have two types of temperature control structures: one uses a mechanical knob control, where temperature adjustment is achieved through the interaction of a gear set and the knob. This structure is highly sensitive to position; even slight differences in position can cause the gears to slip and prevent temperature adjustment. Furthermore, it is costly to produce and lacks a premium appearance. The second type uses an electronic button control, such as the glass electric kettle with an LED light disclosed in patent number CN201220381704.4. This type uses a temperature control module within the control circuit board, which includes a heating module, a cooling module, and a constant temperature module. These modules control the temperature via heating, cooling, and constant temperature switches connected to the control circuit board. Users manually press the heating or cooling switch once to raise or lower the temperature by one degree. This intermittent pressing method results in slow temperature adjustment and a monotonous, uninspired operation. Therefore, existing adjustable temperature electric kettles are difficult to meet the needs of most consumers. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems and shortcomings by providing a new human-computer interaction interface for adjusting the temperature of an electric kettle. This interface allows users to slide their fingers across the kettle to adjust the temperature quickly and accurately, meeting their varying water temperature requirements. This continuous sliding temperature adjustment method not only offers novel and smooth operation and more precise temperature control, but also boasts an attractive and high-end appearance, a simple and reliable structure, and low production costs.

[0005] The technical solution of this utility model is implemented as follows:

[0006] The electric kettle with adjustable temperature according to this utility model includes a base, a kettle body mounted on the base, a heating device, and a temperature control device connected to the heating device circuit. The temperature control device includes a main power controller and a sliding temperature control component. The sliding temperature control component includes a touch module connected to the main power controller circuit, a first display, and a touch-sensitive sliding temperature control area that cooperates with the touch module. When a finger slides on the touch-sensitive sliding temperature control area, the water temperature inside the kettle is set through the cooperation of the touch module and the main power controller. The first display, under the control of the main power controller, is used to display at least the set temperature.

[0007] The touch module is a capacitive touch module (also called a touch sensing chip). Its sliding touch principle is a device that uses touch operations to achieve information input and control. Specifically, it utilizes the capacitance characteristics of the human body, detecting the user's touch operation through capacitive sensing, and adjusting the brightness or temperature of the light based on the touch signal. For example, when a finger touches the screen of the touch sliding temperature adjustment area, it changes the capacitance value of the touch area, and this capacitance change is detected by the touch sensing chip. The touch sensing chip converts the detected capacitance change into an electrical signal, amplifies it, and processes it. The processed electrical signal can be used to control the brightness and temperature of the light. When used for temperature adjustment, the main power controller receives the electrical signal sent by the touch sensing chip, sets the input temperature information, and transmits it to the first display.

[0008] The specific shape of the touch-sensitive sliding temperature-adjusting area can be determined according to the user's needs. For example, the touch-sensitive sliding temperature-adjusting area can be formed into a circular touch area, an arc-shaped touch area, or a straight strip-shaped touch area. Preferably, the touch-sensitive sliding temperature-adjusting area is elongated and set on the surface of the base. More preferably, it is an arc-shaped elongated area.

[0009] Furthermore, the specific location of the touch-sensitive sliding temperature adjustment area can be set according to the user's needs, such as being located on the side of the kettle body, on the handle of the kettle body, or preferably on the upper surface or side of the base shell. To enable different light colors to indicate different temperatures during sliding temperature adjustment, thereby improving the visual effect and accuracy of temperature control, this invention also includes a temperature adjustment indicator light connected to the main power controller. This indicator light displays different light colors for different set temperatures. Further, the temperature adjustment indicator light is a light strip installed at the touch-sensitive sliding temperature adjustment area; the upper surface of the light strip forms the touchscreen of the touch-sensitive sliding temperature adjustment area. Alternatively, a light-transmitting dustproof plate can be provided above the light strip, forming the touchscreen of the touch-sensitive sliding temperature adjustment area. Preferably, the light strip is a straight or curved light strip with an inverted T-shaped cross-section, and the upper surface of the base has a mounting groove for installing the light strip and exposing its upper end. Further, the base also includes a cover that reliably fixes the touch module and the temperature adjustment indicator light together to the inner surface of the shell.

[0010] Furthermore, this invention also includes a water level detection module mounted on the kettle body for detecting the water level inside the kettle. The water level detection module is connected to the main power controller and the first display. The first display can be used to display the water level inside the kettle when the sliding temperature adjustment component is not being used for temperature adjustment. Of course, this invention can also have a separate water level display, but it is preferred to share the first display.

[0011] Furthermore, this utility model also includes a temperature sensing device installed on the kettle body for detecting the real-time water temperature inside the kettle, and a second display, the second display being used to at least display the measured temperature of the water inside the kettle.

[0012] To enable the present invention to dechlorinate the water in the kettle before boiling water, the present invention also includes a dechlorination button switch connected to the power main controller for dechlorinating the water in the kettle, and the second display is used to display a dechlorination indicator when the dechlorination button switch is activated.

[0013] Furthermore, a decorative light ring connected to the main power controller is provided between the kettle body and the base.

[0014] To make the functions of this utility model more diverse, a teapot that can be taken out is also provided on the top of the kettle body.

[0015] To enable this invention to be used in high-altitude areas, it also includes a high-altitude detection and control module connected to the main power controller.

[0016] The advantages of this utility model compared with the prior art are:

[0017] This invention employs a sliding temperature control component structure, consisting of a touch module connected to the main power controller circuit, a first display, and a touch-sensitive sliding temperature control area that works in conjunction with the touch module. This provides a novel human-machine interface, allowing users to adjust the temperature quickly and accurately by sliding their hand across the touch-sensitive area to meet varying water temperature requirements. Furthermore, this continuous sliding temperature control method is not only novel and smooth to operate, but also offers more precise temperature control. It boasts an attractive and high-end appearance, a simple and reliable structure, and low production costs, effectively solving the problems of existing temperature-adjustable electric kettles that are either complex in structure, require high-end components, and are of low quality, or have slow temperature adjustment speeds and monotonous, uninspired operation methods. Furthermore, this invention also includes a temperature indicator light structure that displays different light colors for different sliding temperatures. When the temperature is set by touching the sliding temperature adjustment area, the light color of the indicator light changes with the sliding position, which not only provides a good visual effect and indication function, but also allows the operator to adjust the temperature more accurately based on the color change of the temperature indicator light, thus facilitating precise temperature control.

[0026] Figure 6 This is the electrical schematic diagram of this utility model. Detailed Implementation

[0027] like Figures 1-6As shown, the electric kettle with sliding temperature adjustment according to this utility model includes a base 1, a kettle body 2 mounted on the base 1, a heating device 3, a temperature control device electrically connected to the heating device 3, and a power plug. The kettle body 2 is equipped with a handle 21 (also called a carrying handle) and a faucet 22. The temperature control device includes a main power controller 4, a sliding temperature adjustment component 5 electrically connected to the main power controller 4, and a power switch 10. A light ring can also be installed at the power switch as a power on / off indicator. The sliding temperature adjustment component 5 includes a touch module 51, a first display 52, and a touch-sensitive sliding temperature adjustment area 53 that cooperates with the touch module 51. When a finger slides on the touch-sensitive sliding temperature adjustment area 53, the water temperature inside the kettle body 2 is set through the cooperation of the touch module 51 and the main power controller 4. The first display, under the control of the main power controller, is used to display at least the set temperature. The touch module 51 is a capacitive touch module. Specifically, when a finger slides across the touch-sensitive temperature control area 53, the touch module 51 converts the sensed capacitance change into an electrical signal and sends it to the power main controller 4. After receiving the signal, the power main controller sets the input temperature information and transmits it to the first display. The first display shows the set temperature information, thereby setting the water temperature inside the kettle 2.

[0028] Furthermore, the sliding temperature control in this invention can be steplessly adjusted or set to adjust multiple range values.

[0029] The touch-sensitive sliding temperature control area 53 can be made into a circular touch area, an arc-shaped touch area, or a straight strip-shaped touch area. For example... Figure 1 As shown, the present invention preferably features an arc-shaped, elongated touch area. The touch-sensitive sliding temperature-adjusting area 53 is located on the upper surface of the base 1 shell.

[0030] Furthermore, the sliding temperature control assembly 5 also includes a temperature control indicator light 55 connected to the main power controller 4. This indicator light 55 displays different light colors for different sliding temperature settings. Further, the temperature control indicator light 55 is a light strip installed at the touch sliding temperature control area 53. The upper surface of the light strip can directly form the touchscreen of the touch sliding temperature control area 53. For example, if the light strip is a straight or curved light strip with an inverted T-shaped cross-section, the upper surface of the base 1 has a mounting groove for installing the light strip and exposing its upper end. The base also has a pressure cover 54 that reliably fixes the touch module and the light strip together to the inner surface of the housing. Figures 2-4bAs shown. Furthermore, the touch module 51 has a reflective groove positioned below the light strip. This allows the lower cover to reflect light. The light strip is made transparent, providing excellent light transmission. Alternatively, the light strip can be installed inside the base, with a light-transmitting dustproof plate on the top of the base corresponding to the light strip. This light-transmitting dustproof plate forms the touchscreen of the touch sliding temperature-adjusting area 53. The base also has a cover 54 that reliably fixes the touch module and light strip together to the inner surface of the base. Figure 5a and Figure 5b As shown.

[0031] This invention also includes a water level detection module 23 mounted on the kettle body 2 for detecting the water level inside the kettle body 2. The water level detection module 23 is connected to the power main controller 4 and the first display 52. ​​The first display 52 can display the water level inside the kettle body 2 when the sliding temperature adjustment component 5 is not performing temperature adjustment operation. The water level detection module 23 includes a water level probe plate and a water level probe plate cover mounted on the side wall of the kettle body. This invention also includes a temperature sensing device (NTC) mounted on the kettle body 2 for detecting the real-time water temperature inside the kettle body 2 and a second display 7. The second display 7 is used to display at least the measured temperature of the water inside the kettle body 2.

[0032] This utility model also includes a dechlorination button switch 6 connected to the main power controller 4 for dechlorinating the water in the kettle body 2. The dechlorination button switch is surrounded by an indicator light ring. The second display 7 displays a dechlorination indication when the dechlorination button switch is activated.

[0033] A decorative light ring 8, connected to the main power controller 4, is provided between the kettle body 2 and the base 1. Furthermore, a kettle seat, connected to the base 1, is provided at the bottom of the kettle body 2. The heating device 3 is installed inside the kettle seat, and the decorative light ring 8 is installed at the connection between the kettle bottom and the base 1. The color of the decorative light ring can vary with the ambient temperature (low bright red for room temperature -40 degrees Celsius, medium bright red for 41-70 degrees Celsius, and high bright red for 71-100 degrees Celsius). A snap-action thermostat and a buzzer are also connected to the main power controller. The heating device includes a heating element and a heat-conducting plate. The heating element includes a water-boiling heating element and a heat-insulating heating element. Each of the water-boiling and heat-insulating heating elements is connected to a corresponding snap-action thermostat.

[0034] To facilitate tea brewing and coffee making, the pot body 2 is also equipped with a removable lid or teapot 9.

[0035] The working principle of this utility model will be further described below with reference to the accompanying drawings:

[0036] First, plug in the power cord. All indicator lights, the first display screen, and the second display screen will light up for 3 seconds. After a buzzer beeps, the device will turn off. Press the power button once. The buzzer will beep again, the first display screen will show the current water level, and the second display screen will show the current water temperature in the kettle. The red indicator light on the power switch will illuminate. In standby mode, adjust the temperature by sliding your finger from right to left on the curved light strip on the base. This embodiment allows for 5 temperature range settings. For example: when the first display screen shows 75 degrees Celsius, the green light on the temperature adjustment indicator will stay on. Continue sliding until the first display screen shows 85 degrees Celsius, then the green and light blue lights on the temperature adjustment indicator will stay on. Then slide until the first display screen shows 90 degrees Celsius, then the green, light blue, and dark blue lights on the temperature adjustment indicator will stay on. Continue sliding until the first display screen shows 95 degrees Celsius, then the green, light blue, dark blue, and orange lights on the temperature adjustment indicator will stay on. Finally, slide until the first display screen shows 100 degrees Celsius, then the green, light blue, dark blue, orange, and red lights on the temperature adjustment indicator will stay on. The specific temperature setting can be adjusted as needed.

[0037] Once the set temperature is determined, the first display screen shows the set temperature and flashes 5 times. At this point, the electric kettle enters the boiling / heating state. When the water temperature inside the kettle reaches the set temperature, the buzzer beeps three times, and the indicator light on the power switch changes from red to blue, indicating that it has entered the keep-warm mode. When the temperature drops 5 degrees Celsius below the set temperature, the keep-warm heating element will heat the kettle until the set temperature is reached, then stop heating and cycle back to keep-warm. For example, if the temperature is between 95-100 degrees Celsius, it will keep warm until it reaches 90 degrees Celsius. If the temperature drops below the set 85 degrees Celsius, the keep-warm heating element will heat the kettle until it reaches 90 degrees Celsius, then stop heating and cycle back to keep-warm.

[0038] Water level detection and determination:

[0039] In this embodiment, the water level detection is divided into four segments: 1.0L / 2.0L / 3.0L / 4.0L, from the bottom of the kettle to the spout. When the water level is below the minimum 1.0L, the first display screen (also called the set temperature and water level display module) flashes "000" to indicate that water needs to be added. When the water level is above 4.0L, the buzzer sounds three times to indicate that the kettle is full.

[0040] To remove chlorine: In standby mode, lightly touch the chlorine removal button switch. The blue indicator light on the chlorine removal button switch will light up, and the light ring will turn purple. The second display screen (also called the measured temperature or chlorine removal display module) will display "CL". After heating to full power until boiling, the heating element will stop heating. The heat preservation heating element will continue to boil water for 1 minute and then enter the heat preservation state. The light on the chlorine removal button switch will turn off, and the light ring will change from red to blue. The second display screen will display the real-time heat preservation temperature, which will be maintained at 90 degrees Celsius.

[0041] Definitions of the first and second display screens:

[0042] Second display screen: Displays real-time temperature after power-on, displays "CL" during dechlorination, and displays real-time temperature normally after dechlorination is complete.

[0043] First display screen: Displays the set temperature during temperature setting, such as 75 / 85 / 90 / 95 / 100. After the temperature setting is completed, it displays the water level, such as 1.0L / 2.0L / 3.0L / 4.0L.

[0044] Program code: When the device is off, press and hold the power switch button for 3 seconds. The device will display H22 and then turn off after 3 seconds.

[0045] Although this invention has been described with reference to specific embodiments, such description is not intended to limit the invention. Other variations of the disclosed embodiments, based on the description of this invention, will be foreseeable to those skilled in the art, and such variations should fall within the scope defined by the appended claims.
