Description

The technical field to which the invention relates

The present invention relates to small household appliances, more specifically to a food processor and a method for controlling the display of its interface.

State of the art

With the development of science and technology, more and more types of food processors appear. They can be divided into ordinary food processors, ordinary soy milk making machines, raw soy milk making machines, cell wall breaking machines and other kinds of food processors according to their functions. However, it is also possible to classify food processors according to the type of bowl - to the food processor with a cooling bowl and food processor with a heating bowl.

Given that currently, food processors with different bowls or functions have different setting procedures and touch panels with limited dimensions, touch panels of different food processors are printed with functional options and control options that correspond to such functions. As a consequence, these food processors are sold separately.

In other words, the functions in question are too simple and the functional integration is insufficient for the food processor, making it very difficult to meet the diverse consumer demands.

The present invention is described below with reference to the accompanying drawings with consideration of individual variants of its implementation.

It should also be noted that as used herein, scientific and technical terms have the same meanings as those commonly known to a person skilled in the art to which the present invention belongs, unless otherwise specified.

Unless otherwise stated, expressions used throughout the text of the invention that denote relative directions and movements, such as "up" and "down" or "up" and "down", generally refer to the directions and movements of components with an orientation shown in the drawings, or the orientation of these components themselves in a vertical direction perpendicular to the direction or direction of gravity. Likewise, as used herein to facilitate understanding of the description, expressions such as "interior" and "exterior" refer to interior and exterior spaces with respect to the profiles of the components themselves, but these expressions do not limit the scope of the invention.

As shown in FIG. 1-10, the food processor contains a base 10, a control unit, and two or more different types of bowls. On the base 10 there is a special element for determining the type of accessory, made with the ability to recognize the type of bowl, and sending a corresponding signal of the type of bowl depending on which bowl is installed on it. The control unit receives a bowl-like signal in order to call the corresponding control program and display the corresponding control interface on the touch panel 11, the control interfaces being displayed, respectively, when irradiated with light of different wavelengths.

In this way, the food processor can call up the appropriate operating program depending on the type of bowl, so that the base 10 can interact with different bowls to carry out different operations. In addition, the food processor can solve the problem of the small size of the touch panel and achieve the interface control according to the type of the bowl, thus ensuring the reliable performance of its various functions. The touch panel of such a device is capable of expanding the functional menu two to three times or even more on a limited display area. In addition, its operation is quite simple and the interactive content is of high quality.

That is, an advantage of the food processor according to the present invention is that it is one machine for many tasks and has a high functional integration.

In accordance with the invention, the bowls include two or three of the following bowls: a cooling bowl 20 with a mixing knife, a heating bowl 30 with a mixing knife and heating element, and a bowl 40 for grinding raw materials with an extrusion mill 50. As a cooling bowl 20 and heating bowl 30 can be used to break the cell walls. In other words, the user only has to purchase a set of products designed for different processing requirements, with a selection of different types of bowls, while the control interface can be switched manually or automatically by selecting the desired bowl. This means that different requirements for the operation of a large number of bowls are met by using a small number of touch keys 12 on the same touch panel.

According to the invention, the element for determining the type of accessory comprises a determination chain with a determination terminal, and the bowl comprises a structure for marking the accessory, coordinated with the determination terminal; After the interaction of the structure for marking the accessory with the terminal determining device has occurred, the electrical parameters of the determining circuit are changed in such a way that a signal of the accessory type is generated, and this signal of the accessory type is sent to the control unit, which calls the corresponding control program. The type of the bowl can be determined by the definition circuit and the corresponding control program is called in order to display the corresponding control interface. In this way, the detection circuit automatically detects the type of bowl, thereby increasing the degree of automation of the food processor, thus meeting the needs of users of different ages. When the user replaces the bowl, the corresponding control program will also change in a timely manner, which significantly reduces the difficulties in controlling the operation of the food processor, and also increases its operational reliability and ease of use. It can of course also be done with an additional mode switch.

As shown in FIG. 11, the food processor may also include a power circuit that supplies AC voltage to the control box, whereby the control box supplies electrical power to the electrical appliances so that each component of the food processor can function properly. The AC voltage source can be the input mains voltage, which is converted by the power supply circuit to 5 V DC, which is then supplied to the control unit. After powering on the control unit, it detects the type of bowl using the bowl detection circuit (or by manual setting) and activates the display area necessary to display the interface corresponding to this bowl, after which it calls the corresponding program and finally performs subsequent operations with heating or cooling bowl.

Optionally, a microprocessor control system is used as a control unit.

Depending on the specific detection principle, mainly the three detection modes described below can be applied.

The first mode is the definition of a trigger type.

The detection terminal is equipped with a trigger switch, the marking structure is a trigger element, and the trigger switch is actuated by a trigger element, after which the trigger switch sends the corresponding accessory type signal, and the control unit receives this accessory type signal in order to call the corresponding control program ... This detection mode ensures reliable operation with protection against tampering, so that the probability of erroneous start-up or failure is rather small.

More specifically, a push-type switch is used as the trigger switch, and a push-type structure made on the bowl is used as the trigger element. When the bowl is installed on the base 10, the pushing structure pushes the trigger switch to change the operating state of the detection circuit, and the control unit calls the corresponding control program according to the given operating state of the detection circuit. The type of bowl is determined by mechanical pressing, which is characterized by lightness and minor errors.

The second mode is sensory type detection.

The terminal definition device is equipped with a touch switch, while the marking structure is a sensitive element. After the touch switch has recognized the sensor, this switch sends the corresponding accessory type signal, and the control unit receives this accessory type signal in order to call up the corresponding control program. This detection mode is characterized by a convenient and uncomplicated operation. The user only needs to install the bowl on the base 10 without carrying out other operations, while the touch switch automatically recognizes the sensitive element, providing automatic coordination and calling of programs.

More specifically, a magnetic type switch is used as the touch switch, and a magnetic device is used as the sensor. When the bowl is installed on the base 10, the magnetic device attracts the magnetic switch to change the operating state of the detection circuit, and the control unit calls the corresponding control program according to the given operating state of the detection circuit.

As shown in FIG. 14, a reed switch is used as a touch switch. This reed switch is mounted on base 10. The magnet is not installed on the heating bowl, it is mounted on the bottom of the cooling bowl 20. The detection circuit detects the high and low levels of the P1 terminal of the control unit, which makes it possible to find out what kind of bowl is installed on the base 10.

If the heating bowl 30 is used as the bowl, the magnet is not provided, the reed switch is not attracted to the heating bowl, and the P1 terminal of the control unit is high. If the cooling bowl 20 is used, then the magnet installed on it is located close to the reed switch, this switch is closed, and the output P1 of the control unit is low. It is easy for the user to perform detection, observation and control operations by determining the set type of the bowl by the terminal P1 of the control unit and displaying this type of bowl on the display screen 60.

When classified according to the function of the bowls, they can be divided into a regular bowl (which can be a cooling or heating bowl) with a mixing knife and a bowl 40 for grinding raw materials with an extrusion mill 50. Currently, in the case of using a bowl for a food processor, a magnet on such is not installed more often, the reed switch is not attracted to it, and the P1 output of the control unit is high. If the bowl 40 is used for grinding raw products, then the magnet installed on it is located close to the reed switch, this switch is closed, and the terminal P1 of the control unit is low. And in this case, too, the type of the installed bowl is determined by measuring the level of the output P1, and it is displayed on the display screen 60.

The third mode is the determination of changes in electrical parameters.

The determining terminal contains wiring leads, and the marking structure is an electrical component. The electrical parameters of the detection circuit are changed to generate an accessory type signal after the electrical component is connected to the wiring terminals. In this case, a change in electrical parameters can be a change in current parameters or a change in high and low levels.

For this determination mode, two specific embodiments can be used, which are described below.

Option I

As shown in FIG. 12, the electrical component is a thermistor, and the bowl is mounted on the base 10. The thermistor is connected to the detection circuit through wiring terminals, the electrical parameters of the detection circuit are changed according to different resistance values of the thermistor, and the control unit calls the corresponding control program.

More specifically, it is possible to install a thermistor in one bowl and not install it in the other. So, for example, if the cooling bowl 20 and the heating bowl 30 are used as bowls, then the NTC thermistor is installed not on the cooling bowl 20, but on the heating bowl 30. When the power is supplied, the control unit determines different values by means of the AD conversion. to distinguish the cooling bowl 20 from the heating bowl 30, and displays this view of the installed bowl on the display screen 60.

In addition, thermistors with different resistance values can be provided on the bowls. As an example, a bowl for a conventional food processor and a bowl 40 for chopping raw products can be used. Install two thermistors with different resistances, respectively, one on the bowl for a conventional food processor and the other on the bowl 40 for grinding raw products. When power is applied, the control unit detects different values by means of AD conversion in order to distinguish between the bowl for a conventional food processor and the bowl 40 for grinding raw materials, and displays this type of installed bowl on the display screen 60.

Option II

As shown in FIG. 13, there are two wiring terminals, respectively, a high terminal and a ground terminal, and a connector is used as an electrical component. When both pins of the connector are connected to the two wiring pins of the detection circuit, a low signal is sent to the control unit to invoke one control program. If the connector is connected only to the high level pin, then a high level signal is sent to the control unit in order to call another control program.

In other words, one terminal of the connector of one of the bowls is grounded, and the same terminal of the other bowl is suspended in the air, while the levels of the terminals of the control unit are determined using the following circuit to determine the type of bowl installed.

If the heating bowl 30 is used as the bowl, then terminal P1 of the control unit is high. If the cooling bowl 20 is used as the bowl, then terminal P1 of the control unit is low. The type of the installed bowl is determined by pin P1 of the control unit and is displayed on the display screen 60.

If a conventional food processor bowl is used as the bowl, the P1 pin of the control unit is high. If the bowl 40 is used as a bowl for grinding raw materials, then the output P1 of the control unit is low. The type of the installed bowl is determined by pin P1 of the control unit and is displayed on the display screen 60.

From the above, it follows that when using the food processor of the above-described configuration, the method for controlling the display of the interface comprises the following steps: determining the type of the bowl mounted on the base 10, calling the coordinated control program according to the type of the bowl, and displaying the corresponding control interface. More specifically, after the bowl is placed on the base 10, the interaction between the accessory marking structure on the bowl and the detection circuit changes the electrical parameters of the detection circuit to determine the type of bowl.

As shown in FIG. 15, in addition to the above-described method for calling the control program after determination, it is provided that one of the cups does not have a structure for marking the accessory. The control unit is configured to first call the default control program. When a bowl that does not have a structure for marking an accessory is installed on the base 10, the electrical parameters of the detection circuit do not change and the control unit calls the default control program, and when a bowl equipped with a structure for marking an accessory is installed on the base 10, the electrical parameters of the detection circuit change as follows, to generate a signal of the type of membership in order to call the corresponding NC program. Thus, when power is applied, some traditionally used control program will remain in reserve. If the installed bowl body is not changed, the current default control program will be executed.

In accordance with the invention, a touch panel 11 is mounted on the base 10, which has a display area and a row of touch keys 12, the display area having a row of display positions 111, which are either all or partially provided with corresponding touch keys 12. Each display position 111 is provided display markers 112, wherein at least two display markers 112 overlap or partially overlap each other, or are placed in at least one adjacent display position 111 next to each other, and different display markers 112 located at the same position 11 displays are displayed, respectively, when irradiated with light of different wavelengths. Certain specific processes are illustrated in the flowchart of FIG. sixteen.

In addition, the food processor further comprises an actuator and a light source module adapted to irradiate the touch panel 11. The light source module is located in the base 10 and is configured to selectively emit light of different wavelengths in order to provide a simultaneous display of one marker 112 display at the same display position 111 by sensing light of the appropriate wavelength, and enable display markers 112 in all or a portion of display positions 111 to simultaneously create color. The control unit is connected to the light source unit in order to adjust the wavelength provided by the light source unit, the control program includes control logic corresponding to the currently displayed display marker 112, and the touch keys 12 are connected to the control unit. The actuator is located in the bowl or in the base 10, and when the corresponding touch key 12 is pressed, execution of the control mode starts with the current control interface in order to perform the required cooking operation.

It should be noted that the expression "create color" as used herein means "display color". That is, when the light source unit does not emit light, the display markers 112 are not visible to the naked eye. These display markers 112 can only become visible to the naked eye when these markers 12 are illuminated with light of the appropriate wavelength.

If necessary, the display marker 112 can be made by processing light-sensitive or filtering or chromophore material. In the case of a light-sensitive medium, this medium is irradiated with the appropriate light to initiate the process of creating color with this medium, thereby displaying the desired structure. In the case of a filter medium, given the different wavelengths of light, two or more optical materials are used in the same position, and given the principle of filtering, different wavelengths of the light source cause different materials to produce color. If a chromophore material is used, then a coating with different chromophores is taken as an optical material, in which this material is combined with some transparent material in order to allow light to pass through it only of a very specific wavelength. Optionally, display markers 112 are display words and / or pictures.

It should be noted that the touch keys 12 need not correspond to all of the display positions 111.

Likewise, not all display positions 111 need to include two or more touch keys 12. As a consequence, it may happen that during the same period of time, some of the display positions 111 will not produce color.

In accordance with the specific embodiment shown in FIG. 7 and 8, two display markers 112 are applied at each display position 111. The light source unit can selectively display the first wavelength light and the second wavelength light so that two corresponding display markers 2 are displayed. When the light source unit emits light of the first wavelength, the first display marker 112 generates color, and the second display marker 112 at the same display position 111 is hidden. When the light source unit emits light of the second wavelength, the second display marker 112 generates color, and the first display marker 112 at the same display position 111 is hidden. More specifically, in FIG. 7 shows the control interface corresponding to the cooling bowl 20, and FIG. 8 - control interface corresponding to heating bowl 30.

More specifically, the first wavelength light can be adjusted to be blue and the second wavelength light to orange. Taking a chromophore material as an example, when the light source unit emits light of a long wavelength (orange), a display marker 112 made of an orange chromophore material is displayed, while no other portions of color are produced. When the light source unit emits light of a short wavelength (blue), a display marker 112 made of a blue chromophore material is displayed, while no other portions of color are produced.

As shown, for example, in FIG. 5 and 6, if orange light is emitted, the touch panel 11 is displayed as shown in FIG. 5, with markers a-f shown for illustrative purposes only and can be adjusted to the current product, for example, “Blend”. When emitting blue light, the touch panel 11 is displayed as shown in FIG. 6, in which case markers A-F are shown for illustration purposes only and can be adjusted to the current product. When a and A are in the same position or next to each other, the displayed words are usually different, but may be the same individually.

Display markers 112 may also be displayed sequentially for each control interface as needed.

In accordance with the embodiment shown in FIG. 9, two display markers 112 located at the same display position 111 are superimposed on one another. Thus, when the light wavelength of the light source unit changes, the two display markers 112 can switch so that color is generated.

In accordance with the embodiment shown in FIG. 10, two display markers 112 located at the same display position 111 are adjacent to each other. Thus, when the light wavelength of the light source unit changes, the two display markers 112 can switch so that color is generated. Their adjacent arrangement has the advantage that application difficulties are reduced, but the corresponding space occupied by them becomes larger. Display markers are selected based on the actual needs of this particular product.

In accordance with one embodiment not shown, two display markers 112 located at the same display position 111 are partially overlapped with one another. Thus, when the light wavelength of the light source unit is changed, the two display markers 112 can also switch so that color is generated.

Depending on the type of the above-described bowls, at least two control programs are provided, namely a cooling bowl mode program, a heating bowl mode program and a bowl mode program for grinding raw materials, wherein the light wavelength of the light source module is adjusted in accordance with an accessory type signal in order to display the corresponding cooling bowl program, heating bowl program and bowl program for grinding raw materials. Thus, the control unit contains two or more interface control modules, each of which has different control programs.
