Description

Cooking device with temperature display unit and method of controlling same

technical field

The present invention generally relates to a cooking appliance and a method of controlling the cooking appliance, and more particularly to an oven range having an oven and cooktop combination and a method of controlling the oven range .

Background technique

This oven range includes a cabinet-shaped main body, an oven inside the main body, and a cooktop with at least one heating unit on the upper part of the main body. Electricity or gas is used as energy for heating food.

For oven ranges, the control panel is mounted either on the front of the main body (usually the upper side of the oven door) or on the top. The control panel is a user interface having a plurality of buttons, keypads, etc., so that a user can set a cooking mode or various conditions required for cooking. The control panel may include a display device that allows the user to view currently set cooking modes or conditions, cooking progress status, and the like.

The oven range includes an oven in front of which is provided a door for selectively opening and closing the oven. A heater is installed in the oven. The temperature inside the oven is raised by applying electricity or the combustion of gas to heat the heater so that any food inside is heated. The control panel is provided with a display device such as a 7-segment module or a liquid crystal display (LCD) panel to display the temperature inside the oven. Therefore, when using the oven, the user recognizes the current temperature of the oven by observing the temperature displayed as an image on the display device.

In order to allow a user to correctly recognize the temperature of the oven from within a system that displays the temperature of the oven in an image at a relatively long distance, a display device such as a 7-segment module or an LCD panel for displaying the image should have a sufficient size. In particular, the temperature display unit should have good visibility in order to check the temperature of the oven range while cooking by the oven range in the kitchen during another work at a place away from the oven range.

However, from the viewpoint of size limitation and high-quality design of the control panel, it is difficult to form a sufficient size of the existing display device, so that the image display unit for displaying the temperature cannot help to have a smaller size. The small size of the display device somewhat makes it difficult to identify the current oven temperature at a location remote from the oven cooker.

In an oven range, a cooktop has a structure in which a radiant heating unit is installed on an upper portion of a main body, and in which a protective plate such as a glass plate or a ceramic plate shields the radiant heating unit. The radiant heating unit located beneath the shield emits heat when powered. Heat is transferred through the shield into the container placed above the radiant heating unit, causing the food in the container to be heated.

When the power supply is started, the radiant heating elements of the cooktop are heated to the target temperature very quickly. In contrast, when the power supply is stopped due to the end of use, it takes a considerable time for the temperature of the radiant heating unit to drop. In a state where the temperature of the radiant heating unit is not sufficiently lowered, the user needs to be careful.

A conventional cooktop is provided with a display unit to display the heating state of the radiant heating unit. The function of this display unit is to warn the user that the radiant heating unit of the cooktop is currently being heated to a relatively high temperature, so the user’s attention is required, and thus the display unit reminds the user to pay attention to the radiant heating unit until the radiant heating unit of the cooktop The temperature of the radiant heating unit drops below a safe temperature for the user to come into contact with the radiant heating unit.

However, when the display unit for displaying the heating state of the radiant heating unit of the cooktop is installed on the upper surface of the cooktop, its height is similar to or lower than the installation height of the cooktop (ie, the main body of the oven range). height) people cannot see the display unit, so it is difficult to check the heating state of the radiant heating unit.

Detailed ways

Embodiments of the invention are described below by referring to examples illustrated in the drawings, in which like reference numerals refer to like elements. The embodiments are described below in order to explain the present invention by referring to the figures.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 18 . Fig. 1 illustrates a perspective view of an electric oven range according to an embodiment of the present invention. As shown in FIG. 1 , a cooking device 102 such as an electric oven range includes a cabinet-shaped main body 104 in which an oven 119 is disposed and a cooktop 107 is disposed on the upper part of the main body. The oven 119 is opened and closed through a door 121 provided with a transparent window 138 . Therefore, when the door is closed, the user can see into the oven 119 through the transparent window 138 . For reference, the oven 119 is provided with an oven heater (first heating unit) (not shown) and an oven temperature detector (see FIG. 3 ), the oven heater is used to heat the air inside, and the oven temperature detector is used to Detects the temperature of the heated interior air. The cooktop 107 includes a plurality of radiant heating units 110 to 113 (second heating units). The main body 114 is provided on its front with a plurality of control knobs 142 to 145 which activate or deactivate the plurality of radiant heating units 110 to 113, respectively.

Electric oven range 102 is electrically controlled in response to user manipulation through control panel 116 . The control panel 116 is provided with various control buttons 154 to 157 which allow the user to select any one of a number of cooking modes, for example, a bake mode (for bread and biscuits), a roast mode (for meat) , heat preservation mode, etc. Further, for example, the control panel 116 is provided with an operation mode cancel button 158, a lighting start button 159, an automatic cleaning button 160, an operation setting button 162, a timer button 163, a cooking time button 164, a completion time button 165, a clock button 166 and a figure pad 168 .

Further, the control panel 116 of the electric oven range 102 includes a temperature display unit 152 together with a display 151 . The display 151 displays the cooking mode and cooking conditions set by the user, the current cooking completion percentage, and the like. The display 151 may be implemented by a 7-segment module or a Liquid Crystal Display (LCD) panel. The temperature display unit 152 functions to display the temperature of the oven 119 and the cooktop 107, and employs a light emitting device such as a high-brightness light emitting diode (LED) capable of differently changing light emission colors to improve visibility. Preferably, the temperature display unit 152 is installed on the opposite upper side of the control panel 116 . Therefore, by installing the temperature display unit 152 on the upper side of the control panel 116 installed to protrude from the top of the main body 104, the user can view the to the temperature display unit 152.

The temperature display unit 152 may include one or more units according to the structure of the cooking device. In other words, if the cooking device is provided with one of an oven and a cooktop, only one temperature display unit 152 may be installed. In contrast, if the cooking equipment is provided with an oven and a cooktop, one temperature display unit 152 may be installed to display the temperature of one of the oven and the cooktop, or two temperature display units 152 may be installed to display the temperature of the oven and the cooktop, respectively. The respective temperature of the hob.

Fig. 2 illustrates the structure of the temperature display unit of the electric oven range in Fig. 1 . As shown in FIG. 2, a plurality of high-brightness LEDs 204 of different colors are installed in a row at regular intervals on the front of a narrow and long printed circuit board 202, and a temperature indicator for driving a plurality of LEDs 204 of an integrated circuit (IC) type is provided. The driver 203 is mounted on the back of the printed circuit board 202 . Thus, the circuitry of the printed circuit board 202 is configured such that the temperature display driver 206 is in electrical communication with the plurality of LEDs 204. The temperature display driver 206 is connected to a control unit (see FIG. 4 ) that controls the entire operation of the electric oven range 102 through a connection cable 208, and controls the on/off, light emission of each LED 204 in response to a control signal from the control unit. color etc. Each LED 204 is preferably an LED module that can emit light in various colors including blue (B), green (G) and red (R).

The printed circuit board 202 is provided with a scattering member 210 that widely scatters light emitted from the LED 204 at the side on which the LED 204 is mounted. Since each LED 204 generates heat, the circuit structure of the printed circuit board 202 is complicated, etc., the LEDs 204 are preferably mounted at a given distance from each other. However, in this configuration, when some or all of the LEDs 204 are turned on, the visibility of the LEDs is slightly reduced, because the LEDs 204 that are already turned on are used as multiple lights due to the spacing between the LEDs 204. An independent light source, rather than a whole light source. Thus, light emitted when some or all of the LEDs 204 are turned on is scattered by the scattering member 210 so that the turned-on LEDs 204 function like a light source. This is preferable so that the visibility of the temperature display unit 152 can be improved.

For example, the printed circuit board 202 and the diffusion member 210 are fixed to the back of the control panel 116 by fixing members such as bolts or adhesive. In the control panel 116 , a portion where the printed circuit board 202 and the diffusion member 210 are fixed is provided with a narrow and long window 212 . The light emitted from the turned-on LED 204 is diffused by the diffusion member 210, and then emitted through the window 212 on the control panel, so that the user can visually recognize the light. If necessary, the diffusion member 210 may directly function as a window, and there is no need to separately install the diffusion member 210 and the window 212 .

FIG. 3 illustrates a block diagram of the control system of the electric oven range in FIG. 1 . As shown in FIG. 3 , the control unit (microcomputer) 312 is connected at its input side to the input of the cooktop temperature detector 310 , the oven temperature detector 402 and the control panel 116 . The input of the control panel 116 corresponds to input buttons on the control panel 116 except for the display 151 and the temperature display unit 152 . The cooktop temperature detector 310 detects the temperature of the radiant heating unit 110 (strictly speaking, the temperature of the radiant heating element of the radiant heating unit 110 ), and provides the detected value to the control unit 312 .

The control unit 312 is connected on its output side to the temperature controller 308 connected to the power supply 306 , the display driver 404 , the temperature display unit 152 and the convection fan motor driver 406 . The temperature controller 308 receives the temperature of the radiant heating unit 110 detected by the cooktop temperature detector 310, and, if necessary, cuts off the power supplied to the radiant heating element so that each of the radiant heating units 110 to 113 None of the temperatures exceeds the preset allowable maximum heating temperature (for example, 56° C.) of the cooktop 107 . Where the cooktop 107 includes a plurality of radiant heating units 110 to 113, such as the electric oven range 102 of FIG. 1 , a cooktop temperature detector 310 is provided for each of the radiant heating units 110 to 113, and The temperature detected by each cooktop temperature detector 310 is supplied to a control unit (microcomputer) 312 which controls the overall operation of the electric oven cooker 102 . The oven heater 408 mentioned in the description of FIG. 1 is also powered by the temperature controller 308 and the temperature of the oven heater 408 is controlled by the temperature controller 308 . The display 151 is driven by the display driver 404, and displays a cooking mode or cooking condition set by a user, a current cooking completion percentage, and the like. The function of the convection fan motor driver 406 is to drive the convection fan motor 410 to rotate the convection fan 412 . A convection fan 412 provides air convection within the oven 119 .

In FIG. 3 , the control unit 312 generates a control signal to display one of the temperatures detected by the cooktop temperature detector 310 and the oven temperature detector 402 through the temperature display unit 152 and provides the control signal to the temperature display driver 206 . The temperature display driver 206 controls the on/off, lighting color, etc. of each LED 204 in response to the control signal provided from the control unit 312, thereby allowing the temperature and oven temperature of each of the radiant heating units 110 to 113 of the cooktop 107 Any one of the temperatures in 119 is displayed by temperature display unit 152 . Specifically, when the temperature of each of the radiant heating units 110 to 113 of the cooktop 107 is displayed through the temperature display unit 152, the control unit 312 controls the temperature display driver so that if the number of radiant heating units is two or more, the highest temperature in the radiant heating unit is displayed as a representative temperature of the cooktop 107 .

Expressions used in the present invention are defined as follows.

"The temperature of the heating unit" refers to the temperature of the air inside the oven 119 detected by the oven temperature detector 402 or the temperature of each of the radiant heating units 110 to 113 of the cooktop detected by the cooktop temperature detector 310 .

"The change in the color of the temperature display unit" refers to the change in the color of the temperature display unit 152 due to the light emitted from each light-emitting element (that is, each LED 204) constituting the temperature display unit 152, and the change of the color of the temperature display unit 152 by the light emission of each LED 204. The color of the temperature display unit 152 changes due to on/off.

The "representative color of the temperature display unit" refers to the most prominent color of the temperature display unit 152, which is formed by turning on a major number of light-emitting elements (i.e., LEDs 204) constituting the temperature display unit 152 . The related concept of "representative color" refers to a small-scale "highlight" of color formed by turning on a relatively small number of LEDs 204. For example, if seven of the nine LEDs 204 are turned on to blue (B) and the others are turned on to red (R), then the "representative color" is blue (B) and the "highlight Zone" is "Red (R)".

"Heating temperature range" refers to the temperature range to which the oven 119 or cooktop 107 is not heated to the highest allowable heating temperature to which the oven 119 or cooktop 107 can be heated. For example, when the maximum allowable heating temperature at which the oven 119 can be heated is 280°C, the oven heater 408 is adapted not to exceed the temperature of 280°C by cutting off power supplied thereto. For reference, the temperature to which the oven 119 or the cooktop 107 cannot be heated at all may not be limited to a specific temperature because the temperature to which the oven 119 or the cooktop 107 cannot be heated may vary depending on the surrounding temperature, but the oven The temperature to which the 119 or cooktop 107 cannot be heated may be determined to have an upper limit, eg "less than a predetermined temperature". For example, when the heating temperature range of the oven 119 is divided into three temperature sections, for example, the lowest temperature section may be set as "100° C. or lower section".

FIG. 4 illustrates a first embodiment of the temperature increase of the heating unit displayed by the temperature display unit of the electric oven range in FIG. 1 . In FIG. 4 , the temperature up to the maximum allowable heating temperature is taken as the entire temperature display segment, and the temperature segment to which the currently raised temperature of the heating unit belongs is displayed by changing the color of the temperature display unit 152 . According to the display method of FIG. 4 , the heating temperature range of the heating unit (specifically, the heating unit arranged in the oven 119 or the stove 107 ) is divided into a plurality of temperature segments, and the current temperature of the heating unit is based on the temperature of the temperature display unit 152. Color changes are displayed using a temperature segment. The temperature segment is not divided into too many segments, but can be segmented in two to four ranges, for example, to improve visibility at long distances. Further, preferably, in order to improve the visibility so that the user can intuitively recognize the temperature change of the heating unit, the temperature segment belonging to the relatively lower temperature is displayed with a cool primary color, for example, blue, while the temperature segment belonging to the relatively higher temperature The temperature segment of the temperature is displayed with a warm base color, for example, red.

When the current temperature of the heating unit is less than 100°C, all LEDs 204 are turned on as blue (B), when the current temperature is in the range from 101°C to 200°C, they are turned on as green (G), when the current When the temperature is in the range from 201°C to 500°C, it is turned on to red (R). Thus, the temperature of the heating unit displays different colors according to the range in which the temperature falls. Therefore, the user can easily check which zone the current temperature of the heating unit belongs to just by looking at the luminous color of the temperature display unit 152 at a position away from the electric oven range 102 .

When the temperature of the heating unit reaches the target temperature (for example, 280° C.) set by the user, the entire temperature display unit 152 will blink in red (R) for a predetermined time by activating the temperature display unit 152, as shown in FIG. 4 (IV) , the user can determine that the current temperature of the heating unit has reached the target temperature.

According to the control method in FIG. 15 , the electric oven range 102 includes multiple heating units, especially the heating units arranged in the oven 119 and the stove 107 , and the temperature of any heating unit is displayed by a temperature display unit 152 . As shown in FIG. 15 , it is checked whether any one of the heating units (in particular, the heating units provided in the oven 119 and the cooktop 107 ) is in use (operation 1502 ). If any one of oven 119 and cooktop 107 is not in use, the operation ends. If any of the oven 119 and the cooktop 107 are in use (Yes at operation 1502), then it is checked whether both the oven 119 and the cooktop 107 are in use (operation 1504). If both the oven 119 and the cooktop 107 are in use (Yes in operation 1504), the current temperatures of the oven 119 and cooktop 107 in use are detected and compared with each other (operation 1506). As a result, higher current temperatures in the oven 119 and the cooktop 107 are set for display (operation 1508).

When it is checked that only one of the oven 119 and the cooktop 107 is in use (NO in operation 1504), and when the higher of the current temperatures of the oven 119 and the cooktop 107 that are both in use is set for display , as the next control operation (operation 1510 ), the temperature corresponding to the heating unit in operation is displayed through the temperature display unit 152 . Here, the temperature of the operating corresponding heating unit is displayed using the control method of FIGS. 14A and 14B as described above.

FIG. 16A and FIG. 16B illustrate the effect according to the installed position of the electric oven range in FIG. 1 . According to an embodiment of the present invention, the temperature display unit 152 is installed at a position as high as possible in the electric oven range 102, so that the temperature display unit 152 can be more easily installed at a position slightly lower than the height of the cooktop 107. See.

As shown in Figure 16A, since the display unit for displaying the heating state of the cooktop 107 is installed on the upper surface 1602 of the cooktop 107 in a conventional electric oven range, its height is close to or lower than that of the cooktop 107. A person cannot see the display unit 152 of the cooktop 107, and therefore cannot check the heating state of the cooktop 107. In contrast, since the temperature display unit 152 according to the embodiment of the present invention is installed on the highest side of the control panel 116 installed to protrude from the top of the cooktop 107, the installation position of the temperature display unit 152 is similar to that of the electric oven range. 102 corresponds to the highest position. Therefore, a shorter person (eg, a child) can easily check the inner temperature of the oven 119 and the temperature of the cooktop 107 through the temperature display unit 152 .

Further, as in the embodiment of the present invention, when the temperature display unit 152 is installed at the highest position of the electric oven range 102, taller people (for example, adults) can raise their heads to a certain extent. It is easier to see the temperature display unit 152 , unlike a traditional electric oven range, one has to bend one's head to see the traditional display unit installed on the upper surface 1602 of the cooktop 107 . Therefore, the internal temperature of the oven 119 and the temperature of the cooktop 107 can be checked more conveniently. In other words, during cooking with the stove 17, when the user is close to the electric oven stove 102, as shown in FIG. In one embodiment, the user can check the temperature conveniently through the temperature display unit 152, wherein the temperature display unit is installed on the upper surface 1602 or the front surface 1604 of the electric oven range 102 opposite to the conventional display unit. on a higher position.

FIG. 17 illustrates another embodiment of the control panel of the electric oven range of FIG. 1 . As shown in FIG. 17 , when the cylindrical knob 1770 is mounted on the control panel 1716 , the curved temperature display unit 1752 is disposed around the cylindrical knob 1770 . Thus, the area occupied by the control panel 1716 can be reduced compared to a linear temperature display unit. In particular, when the display 1751 is not provided or the display 1751 has a small size, the curved temperature display unit 1752 preferably prevents the control panel 1716 from being enlarged due to a long linear temperature display unit.

FIG. 18 illustrates another embodiment of a control panel 1816 of the electric oven range of FIG. 1 . As shown in FIG. 18 , in the case of an electric oven range having a display 1851 capable of graphically displaying the temperature of the oven 119 or the cooktop 107 , the size of the display 1851 graphically displaying the temperature is also limited due to its size limitation. In this case, according to an embodiment of the present invention, the temperature display unit 1852 uses a high-brightness light-emitting element to display the temperature of the oven 119 or the cooktop 107 in color. Thereby, the temperature of the oven 119 or the cooktop 107 is generally recognized by the color of the temperature display unit 1852 at a long distance, and can be more accurately recognized at a short distance since it is displayed on the display 1851 as an image. Therefore, in terms of recognizing the temperature of the oven 119 or the cooktop 107, the convenience of the user is improved by the complementarity of the display 1851 and the temperature display unit 1852.

Further, as illustrated in FIG. 18, in addition to the temperature display unit 152, in the case where a display capable of displaying the temperature of the oven 119 or the cooktop 107 in an image 1870 is provided, the display 1851 can be used as means for displaying the temperature of the cooktop 107. . In other words, the temperature of the cooktop 107 is displayed as an image on the display 1851 so that the user can more accurately recognize the lowering state of the cooktop 107 in temperature.

The temperature display unit according to the embodiment of the present invention can be applied to an electric oven range, and can also be applied to a gas oven range.

The position change of the highlighted area in the temperature display unit can be used to display the remaining time required for the temperature of the cooktop to reach the safe temperature, instead of the temperature of the cooktop.

In the temperature display unit, the color of each LED and the highlighted area representing each temperature, and the number of LEDs turned on for the highlighted area can also be variously changed. The color change and blinking pattern of each LED, the change of the highlighted area, etc. can be combined through these various changes, so that more ways to display the temperature can be obtained.

As can be seen from the foregoing, according to the present invention, the temperatures of the oven and the cooktop can be easily recognized by a color change corresponding to a change in temperature of any one of the oven and the cooktop at a location remote from the cooking device.

In particular, the temperature of the cooking device can be generally identified at a long distance and precisely at a short distance.

Further, since the temperature display unit is installed at a position higher than that of the cooktop, any child whose height is lower than that of the cooktop can easily recognize the heating of the cooktop through the temperature display unit according to the present invention. status so that children can safely use the cooking appliance.

Although some embodiments have been described for purposes of illustration, those of ordinary skill in the art will appreciate that various modifications can be made without departing from the scope and spirit of the invention as disclosed in the appended claims , add or replace.
