TECHNICAL FIELD

The present invention relates to the technical field of small household appliances, and more particularly to a food processor and a method for controlling an interface display thereof.

BACKGROUND

With the development of science and technology, there are more and more types of food processors. The food processors can be classified into ordinary food processors, ordinary soybean milk makers, raw soybean milk makers, wall-breaking food processors and other types of food processors according to their functions. However, the food processors can also be classified into food processors with a cooling cup and food processors with a heating cup according to the types of the cups.

At present, since food processors of different cups or functions are provided with different preset proceduresand have touch panels with limited area, the touch panelsof different food processors are printed withfunction options and control options corresponding to such functions. As a result, these food processors are sold separately.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

It should be noted that the embodiments in the present application and the characteristics in the embodiments can be combined mutually in the case of no conflict. The present invention will be described in detail as below with reference to the accompanying drawings by the embodiments.

It should be noted that, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs unless specified otherwise herein.

In the present invention, unless otherwise stated oppositely, the terms used herein to directional relationships and movement, such as “top and bottom or upper and lower” , generally refer to the relationship and movement of the components in the orientation illustrated in the drawings, or refer to the orientation of the components themselves in the vertical, perpendicular or gravity directions. Similarly, in order to facilitate the description and understanding, the terms “inner and outer” used herein refer to the inside and outside with respect to the profiles of the components themselves, but the above-mentioned terms are not intended to limit the present invention.

The present invention provides a food processor and a method for controlling an interface display thereof, in order to solve the problem of low functional integration of the food processors in the prior art.

As shown in FIG. 1 to FIG. 10, the food processor comprises a base 10, a control unit and two or more different types of cups. A utensil type detection element configured to identify the type of cups is provided on the base 10 and sends a corresponding utensil type signal according to the type of the cup placed thereon. The control unit receives the utensil type signal so as to call a corresponding control program and display a corresponding control interface on a touch panel 11, and the control interfaces are displayed respectively under the irradiation of light of different wavelengths.

Thus, the food processor can call a corresponding operation program depending on the type of the cup, so that the base 10 can cooperate with the different cups to achieve various operations. Moreover, the food processor breaks through the area limitation of the touch panel and adjusts the control interfaces depending on the type of the cup so as to ensure that the various functions of the food processor can be achieved reliably. The touch panel of such structure can enlarge the function menu by twice or three times or even more times in the limited display area. Moreover, the operation is simple and the interactive experience is very good.

According to the present invention, the cups comprise two or three of a cooling cup 20 having a mixing cutter, a heating cup 30 having a mixing cutter and a heater and a raw milling cup 40 having an extrusion crusher 50. The cooling cup 20 and the heating cup 30 may be wall-breaking cups. In other words, the user only needs to purchase a set of products to adapt to different processing requirements by changing the different types of the cups, and the control interface can be switched manually or automatically by changing the different cups. That is, the different operation requirements of many cups are met by using a small number of the touch keys12 in the same touch panel.

According to the present invention, the utensil type detection element comprises a detection circuit having a detection terminal, and the cup comprises a utensil marking structure coordinated with the detection terminal； after the interaction between the utensil marking structure and the detection terminal, electrical parameters in the detection circuit change to generate the utensil type signal, and the control unit receives the utensil type signal so as to call a corresponding control program. The type of the cup can be detected by the detection circuit so as to call a corresponding control program to display a corresponding control interface. Thus, the type of the cup is determined automatically by the detection circuit, so that the degree of automation of the food processor can be improved to meet the needs of the users at different ages. When the user changes the cup, the corresponding control program will also be changed timely, thus greatly reducing the difficulty in operating the food processor and improving the operation reliability and convenience of the food processor. Of course, it can also be manually implemented by an additional change-over switch.

As shown in FIG. 11, the food processor also includes a power circuit through which the AC power supply is supplied to the control unit, so that the control unit supplies power to the electrical appliances to ensure the normal operation of each component in the food processor. The AC power supply is a mains electricity input converted to DC 5V by the power circuit so as to be supplied to the control unit for operation. The control unit when energized detects the type of the cup by the cup detection circuit (or manual setting) , and controls a display portion to display an interface corresponding to the cup, calls the corresponding program and then executes subsequent operations of the heating cup or the cooling cup.

Optionally, the control unit is an MCU control system.

According to the different detection principles, there are mainly three detection modes as below.

The first mode refers to a trigger type detection mode.

The detection terminal comprises a trigger switch, wherein the marking structure is a trigger element and wherein after the trigger switch is triggered by the trigger element, the trigger switch sends the corresponding utensil type signal, and the control unit receives the utensil type signal so as to call the corresponding control program. Such detection mode has a good fool-proof effect, and is not easy to be mistakenly triggered and also is not easy to fail.

Specifically, the trigger switch is a push-type trigger switch, the trigger element is a bump structure provided on the cup. When the cup is placed on the base 10, the trigger switch is pressed by the bump structure so as to switch operation state of the detection circuit, and the control unit calls the corresponding control program according to the operation state of the detection circuit. The type of the cup is identified by mechanical pressing, which has the characteristics of easy operation and small errors.

The second mode refers to a sensor type detection mode.

The detection terminal comprises a sensor switch, wherein the marking structure is a sensing element. After the sensor switch senses thesensing element, the sensor switch sends the corresponding utensil type signal, and the control unit receives the utensil type signal so as to call the corresponding control program. Such detection mode has the characteristics of easy and simple operation. The user only needs to place the cup on the base 10 without other operations, so that the sensor switch senses the sensing element automatically to achieve automatic matching and calling of the programs.

Specifically, the sensor switch is a magnetic switch, the sensing element is a magnetic device. When the cup is placed on the base 10； the magnetic device attracts the magnetic switch so as to switch the operation state of the detection circuit, and the control unit calls the corresponding control program according to the operation state of the detection circuit.

As shown in FIG. 14, the sensor switch is a reed switch. The reed switchis provided in the base 10. No magnet is mounted on the heating cup 30 but a magnet is mounted on the bottom of the cooling cup 20. The high and low levels of a P1 pin of the control unit are determined by the detection circuit, thus determining which type of the cup is placed on the base 10.

When the cup is the heating cup 30, there is no magnet, the reed switch is not attracted to the heating cup and the P1 pin of the control unit is at high level. When the cup is the cooling cup 20, the magnet on the cup is close to the reed switch, the reed switch is closed, and the P1 pin of the control unit is at low level. It is easy for the user to detect, observe and operate by determining which type of the cup is placed by the P1 pin of the control unit and displaying the type of the cup by the display screen 60.

When classified by the functions of the cups, the cups may be classified into an ordinary cup (which may be a cooling cup or a heating cup) having a mixing cutter and a raw milling cup 40 having an extrusion crusher 50. At this moment, in case the cupis a food processing cup, the magnet is not mounted on the food processing cup, the reed switch is not attracted to the cup, and the P1 pin of the control unit is at high level. When the cup is the raw milling cup 40, the magnet on the cup is close to the reed switch, the reed switch is closed, and the P1 pin of the control unit is at low level. Similarly, which type of the cup is placed is determined by determining the level of the P1 pin, and displayed through the display screen 60.

The third mode refers to an electric parameter change type detection mode.

The detection terminal comprises wiring pins, wherein the marking structure is an electrical component. The electrical parameters in the detection circuit change to generate the utensil type signal after the electrical component is connected to the wiring pins. The change in the electrical parameters here can be a change in current parameters or a change in the high and low levels.

In such detection mode, two specific embodiments which may be implemented are also specifically described as below.

Embodiment I

As shown in FIG. 12, the electrical component is a thermistor and the cup is placed on the base 10； the thermistor is connected to the detection circuit by the wiring pins, the electrical parameters in the detection circuit change depending on different resistance values of the thermistor, and the control unit calls the corresponding control program.

Specifically, a thermistor may be mounted on one cup and no thermistor is mounted on another cup. For example, when the cups are the cooling cup 20 and the heating cup 30, the NTC thermistor is not mounted on the cooling cup 20 but mounted on the heating cup 30. When energized, the control unit detects different AD conversion values through AD conversion to distinguish the cooling cup 20 from the heating cup 30 and displays which type of the cup is placed through the display screen 60.

In addition, thermistors of different resistances may also be provided on different cups. The ordinary food processing cup and the raw milling cup 40 are taken as an example. Two thermistors with different resistances are mounted on the ordinary food processing cup and the raw milling cup 40 respectively. When energized, the control unit detects different AD conversion values through AD conversion todistinguish the ordinary food processing cup from the raw milling cup 40 and displays which type of the cup is placed through the display screen 60.

Embodiment II

As shown in FIG. 13, there are two wiring pins which are respectively a high level pin and a ground pin, and the electrical component is a coupler. When the coupler has the two connecting pins both connected to the two wiring pins of the detection circuit, the control unit receives a low level signal so as to call one control program. When the coupler is only connected to the high level pin, the control unit receives a high level signal so as to call the other control program.

In other words, one pin of coupler of one of the cups is grounded while asame pin of another cup is suspended in midair, and the levels at the pins of the control unit are determined through the following circuit to determine which type of cup is placed.

When the cup is the heating cup 30, the P1 pin of the control unit is at high level. When the cup is the cooling cup 20, the P1 pin of the control unit is at low level. Which type of the cup is placed is determined by the P1 pin of the control unit and displayed through the display screen 60.

When the cup is the ordinary food processing cup, the P1 pin of the control unit is at high level. When the cup is the raw milling cup 40, the P1 pin of the control unit is at low level. Which type of the cup is placed is determined by the P1 pin of the control unit and displayed by the display screen 60.

From the foregoing, when the food processor with the above structure is used, a method for controlling an interface display comprises the following steps of: determining the type of a cup placed on the base 10, calling a matched control program according to the type of the cup and displaying a corresponding control interface. Specifically, after the cup is placed on the base 10, the interaction between a utensil marking structure on the cup and a detection circuit enables electrical parameters in the detection circuit to change so as to determine the type of the cup.

In addition to the above mentioned method for calling the control program after detection, as shown in FIG. 15, one of the cups is not provided with a utensil marking structure. The control unit initially calls a control program by default. When the cup without a utensil marking structure is placed on the base 10, the electrical parameters in the detection circuit do not change and the control unit calls the default control program； when the cup with a utensil marking structure is placed on the base 10, the electrical parameters in the detection circuit change to generate the utensil type signal so as to call the corresponding control program. Thus, a certain commonly used control program will be on standby when energized. Unless the cup body placed thereon is changed, the current default control program will be executed.

According to the present invention, the touch panel 11 is provided on the base 10 and comprises a display area and a number of touch keys 12, the display area comprises a number of display positions 111 which are all or partially provided with the touch keys 12 correspondingly. Display markers 112 are provided in each display position 111, at least two display markers 112 are superposed or partially superposed or adjacently provided in at least one display position 111, and the different display markers 112 in the same display position 111 are displayed respectively under the irradiation of light of different wavelengths. Refer to FIG. 16 for specific processes.

In addition, the food processor further comprises an execution element and a light source module configured to irradiate the touch panel 11. The light source module is provided in the base 10 and can selectively emit light of different wavelengths so as to enable one display marker 112 in the same display position 111 to be displayed at a same time by sensing light of corresponding wavelength and enable the display markers 112 in all or part of the display positions 111 to develop color at a same time. The control unit is connected to the light source module to adjust the light wavelength of the light source module, and the control program comprises a control logic corresponding to the display marker 112 displayed currently and the touch keys 12 are connected to the control unit. The execution element is provided in the cup or the base 10, when the corresponding touch key 12 is triggered, a control mode under the current control interface is executed to perform a corresponding cooking operation.

It should be noted that the term "develop color"referred to herein means "display color" . That is to say, when the light source module does not emit light, the display markers 112 are invisible to the naked eye. The display markers 112 can be visible to the naked eye only when the display markers 112 are illuminated by the light of the corresponding wavelength.

Optionally, the display marker 112 is formed by processing photosensitive medium material or filter medium material or chromophore material. For the photosensitive medium, the corresponding light is irradiated onto the medium to trigger the medium to develop color, thus displaying a pattern. For the filter medium, due to the different wavelengths of light, two or more optical materials are used in the same position and due tothe filter principle, the different wavelengths of the light source make different contents develop color. For the chromophore material, the optical material is a coating material containing different chromophores, so that this material is combined with a transparent material to allow only a certain wavelength of light to pass through. Optionally, the display markers 112 comprise display words and/or display patterns.

It should be noted that the touch keys12 do not necessarily correspond to all of the display positions 111.

Similarly, not all of the display positions 111 comprise necessarily two or more touch keys12. As a result, it is possible that part of the display positions111 do not develop color over the same time period.

In the specific embodiment of FIG. 7 and FIG. 8, two display markers 112 are coated at each display position 111. The light source module may selectively display light of a first wavelength and light of a second wavelength for respectively displaying the two display markers 112. When the light source module emits the light of the first wavelength, the first display marker 112 develops color and the second display marker 112 is hidden in the same display position111. When the light source module emits the light of the second wavelength, the second display marker 112 develops color and the first display marker 112 is hidden in the same display position111. Specifically, the control interface corresponding to the cooling cup 20 is shown in FIG. 7. And, the control interface corresponding to the heating cup 30 is shown in FIG. 8.

Specifically, the light of the first wavelength may be set as blue light； and the light of the second wavelength may be set as orange light. Taking the chromophore material as an example, when the light source module emits light of long wavelength (orange light) , the display marker 112 made of the orange chromophore material is displayed, and the other parts do not develop color. When the light source module emits light of short wavelength (blue light) , the display marker 112 made of the blue chromophore material is displayed and the other parts do not develop color.

Taking FIG. 5 and FIG. 6 as an example, when orange light is emitted, the touch panel 11 is displayed as shown in FIG. 5, whereina to f are merely for illustrative purpose and may be set according to the actual product, such as "Mix" . When blue light is emitted, the touch panel 11 is displayed as shown in FIG. 6, whereinA to F are merely for illustrative purpose and may be set according to the actual product. When a and A are located in the same position or adjacent to each other, the displayed words are usually different but may also be the same individually.

Optionally, the display markers112 may also be progress display for each control interface.

In the embodiment shown in FIG. 9, the two display markers 112 in the same display position 111 overlap with each other. Thus, when the light wavelength of the light source module is switched, the two display markers 112 may be switched to develop color.

In the embodiment shown in FIG. 10, the two display markers 112 in the same display position 111 are adjacent to each other. Thus, when the light wavelength of the light source module is switched, the two display markers 112 may be switched to develop color. The benefits of the adjacent setting will reduce the difficulty of coating, but the corresponding occupied size will become larger. The display markers are selected according to the actual needs of the actual product.

In the embodiment not shown, the two display markers 112 in the same display position 111 partially overlap with each other. Thus, when the light wavelength of the light source module is switched, the two display markers 112 may also be switched to develop color.
