Description

  The present invention relates to a heating apparatus having a plurality of display units. Specifically, the present invention improves operability by classifying and displaying information on a plurality of display units.

  In recent years, this type of heating apparatus often determines a menu to be used from heating menus prepared in advance, and sets a heating time and a heating temperature. Since this type of heating device is multifunctional and requires a complicated operation procedure, improvement in operability is required.

  The process and result of operation input are displayed as characters and numerical values. By confirming the display, the user can know the input result and the operation procedure. Therefore, the demand for easy-to-understand display is increasing.

  Conventionally, a segment type display tube is often used for the display unit, but there is also a heating device using a dot matrix type display tube.

  In addition, there is also a guide that displays only information necessary in the course of operation according to the operation procedure, and guides the user to set the heating conditions. In addition, since this prior art is not related to the literature known invention, there is no prior art document information to be described.

  Fig.6 (a) is a figure which shows the front door part of the conventional heating apparatus. A handle 31 is provided at the upper part of the door so that the door can be opened and closed. The display means of the present apparatus is composed of a segment type display tube 233 and a display unit 234 which displays a heating menu name provided at the lower part of the door screen 32.

  FIG.6 (c) is a figure which shows the example of a display of the segment system in the conventional heating apparatus. As shown in FIG. 6C, the segment-type display tube 233 realizes display by electrically turning on and off predetermined display segments in FIG. The numbers are displayed by separating them into seven segments like 51, 52, 53, 54, 55, 56, 57 and combining each segment by electrically turning on each segment.

  The segment type display tube can display one display only at a predetermined position, and cannot display different displays at the same position. When there are many types of heating menus, it is not possible to display all menu names, so it is common to display the numbers with a number assigned to each heating menu.

  FIG. 6B is an enlarged view of the display unit 234 showing the name of the heating menu. As shown in FIG. 6B, the correspondence between the number and the heating menu can be confirmed on the display unit 234 indicating the heating menu name. In FIG. 3, the display unit 234 is provided with an illuminating element, and the heating menu being selected is turned on.

  This display method has a problem that if the number of heating menus is increased, a large number of illumination elements are required and cost is increased. Moreover, the display part 234 must be enlarged or a character must be made small, and there also exists a subject that display becomes miscellaneous and legibility falls.

  In contrast, the dot matrix type display tube can display characters and images freely, but the cost is higher than the segment type, and the display cannot be made large in order to reduce costs. .

  When the display unit is small, in order to display a large amount of information, the screen must be switched every fixed time or every input operation, and the information cannot be displayed at the same time. When information is displayed at the same time, the display becomes finer and the visibility is reduced.

  The present invention has been made to solve the above-mentioned problems, and the object of the present invention is to combine a segment type display tube and a dot matrix type display tube to classify and display information, thereby operating It is in providing the heating apparatus which improved the property.

  The heating apparatus of the present invention that solves the above problems includes a heating chamber that houses an object to be heated, a heating unit that heats the object to be heated, a detection unit that detects a physical quantity of the heating chamber or the object to be heated, Input means for inputting heating conditions, display means for displaying the input heating conditions, and control means for controlling the heating means and the display means according to the input heating conditions, the display means being a dot matrix system The display unit and the segment method display unit are configured to display information necessary for input, results input by the input unit, heating conditions, control states, and physical quantities detected by the detection unit, classified by information.

  According to the heating device of the present invention, since a dot matrix type display tube and a segment type display tube are used in combination, a large amount of information can be organized and displayed at the same time in an easy-to-understand manner. This is effective in preventing erroneous operation and improving operability.

  The present invention includes a heating chamber that accommodates an object to be heated, a heating unit that heats the object to be heated, a detection unit that detects a physical quantity of the heating chamber or the object to be heated, and an input unit that inputs heating conditions. A display means for displaying the input heating conditions, and a control means for controlling the heating means and the display means in accordance with the input heating conditions, the display means from a dot matrix system display section and a segment system display section Thus, the information necessary for input, the result input by the input means, the heating condition, the control state, and the physical quantity detected by the detection means are classified and displayed by information.

  As a result, the name of the heating menu can be displayed on the dot matrix display unit, so that there is no need to confirm the correspondence between the number and the heating menu. Information to be displayed on the dot matrix display by selecting the content that you want to alert the user to display on the dot matrix display, and displaying other information and heating conditions that can be displayed in numbers on the segment display Can be reduced.

  Therefore, a large and easy-to-read display is possible, and an erroneous operation can be prevented and the cost can be reduced. Furthermore, information can be confirmed at the same time without switching the screen.

  In addition, since the physical quantity during heating can be confirmed together with the heating conditions and the control state, it is possible to perform an accurate operation in accordance with the progress of heating, and the convenience for the user can be improved.

The display means includes a major classification of a heating menu, a heating menu selected from the major classification, an operation instruction and an input state, an inputted heating time and a heating temperature, a detected physical quantity, a heating function and a control state. And a display unit such as heating finish instruction information, etc., and may display a necessary information in accordance with an operation procedure to guide the operation.

  Thus, the user can operate according to the guidance without referring to the instruction manual, and the operability is improved.

  Further, the display means may simultaneously display the physical quantity detected by the detection means with respect to the input heating condition.

  In addition, one of the display means may be used as a graph display, and a graph that simultaneously displays physical quantities detected with respect to the input heating condition may be used.

  Further, the display means may simultaneously display physical quantities detected with respect to the input heating condition, and switch between numerical display and graph display for display.

  Further, the temperature of the heating chamber or the object to be heated may be detected as a physical quantity and displayed on the display means.

  Further, both the total heating time and the elapsed time may be displayed on the display means.

  One of the display means may be a graph display, and a graph that displays the total heating time and the elapsed time at the same time may be used.

(Embodiment)
FIG. 1 is an external view of the heating device of the present invention, and FIG. 2 is a functional block diagram of the heating device of the present invention.

  1 and 2, the heating apparatus includes a heating chamber 21 that houses an object to be heated, and a heating unit 22 that heats the object to be heated in the heating chamber 21. The heating means includes a high-frequency heating means and a heater heating means, and both of them may be provided.

  A door 1 that can be opened and closed is provided in front of the heating device, and an input means 24 and a display means 23 are provided. The input means 24 inputs to the control means 25 by rotation or pressing.

  In addition, the heating device controls the heating means 22 by the control means 25 based on the input from the input means 24 and displays the heating information on the display means 23. Further, in this heating apparatus, the detection unit 26 detects physical quantities of the heating chamber 21 and the object to be heated, and the control unit 25 displays the information on the display unit 23.

  FIG. 5A is an enlarged view of the front surface of the door 1 in the heating device of the present invention. The difference from the conventional heating device (FIG. 6) is that the display means 235 at the lower part of the door screen 32 and the display part at the lower part of the door are combined with a dot matrix type display tube 231 and a segment type display tube 232 as shown in FIG. This is the configuration.

  FIG. 3 (b) is an enlarged view of the display means 235 and shows the major classification name of the heating menu. In addition, the display unit 235 is configured to be able to light each major classification name independently with an illumination element.

  If each segment display of the segment system is not arranged so that the display does not become too small and does not stick too much to each other, the display becomes miscellaneous and the visibility is reduced. The segment type display tube 232 of FIG. 8 can reduce the number of segments by providing the dot matrix type display tube 231.

  As a result, a blank space is generated as compared with FIG. 3B, and one of the two three-digit number displays 81 and 82 is enlarged, and the number is made a different size. Making the same number display different in size has the effect of visually recognizing that the two displays have different meanings.

  The heating menu includes a menu that allows the user to set heating conditions such as temperature and time (manual heating menu), and a menu that has heating conditions prepared in advance and does not need to be set (automatic heating menu).

  When starting cooking of food, the user inputs heating conditions such as heating output and heating time using the input means 24. Instructions and input values in the input operation are displayed on the display means 23. If necessary, display multiple numbers and characters side by side. The cooking set based on the input information is advanced. During cooking, information indicating the control state such as the remaining time and the output during cooking is displayed on the display means 23.

  4 and 5 are diagrams showing examples of display transitions from the selection of the heating menu to the end of heating. Before input, the first operation description is displayed on the dot matrix type display tube 231 as shown in FIG. By using not only characters but also images, there is an effect that makes it easy to understand. This display (FIG. 4 (a)) may be configured such that the power is turned off to save power when no input time exceeds a certain time.

  First, when the input means 24 is rotated counterclockwise in accordance with the display (FIG. 4A) instruction, a list of manual heating menus is displayed as shown (FIG. 4B). The first menu of the manual heating menu is selected. Here, when the input unit 24 is rotated counterclockwise, the selection menu is changed in the rotation direction, and each menu is displayed as a selection state.

  By displaying this list on the dot matrix type display tube 231, the menu name can be displayed larger than that displayed on the segment type display tube, and the display unit 234 displaying the heating menu name is not required. There are black and white inversion display and blinking display methods for indicating the selected state, but the blinking display has a problem in viewability.

  However, since the segment type display tube cannot switch between the reverse display and the other display at the same position, the dot matrix display tube is effective.

  Next, when a confirmation operation is performed with the input means 24 while the menu to be selected is selected, the heating menu is determined and displayed (FIG. 4C). Visibility is enhanced by displaying the determined menu name larger. This is also effective for elderly people and people with poor vision.

  When it is necessary to input the heating condition, the illumination element of the operation instruction notation 91 is turned on or blinked, and the heating condition type 95 is displayed on the dot matrix type display tube 231 by characters. The heating conditions are set by the input means 24. When there are a plurality of heating conditions that need to be set, after the first heating condition is determined by the input means 24, the next heating condition is set.

At this time, the display becomes (FIG. 4D). The heating condition type 95 is displayed in characters at the same position as in FIG. Thus, the dot matrix type display tube is effective for displaying different character displays having the same role at the same position.

  Further, the set value of the input heating condition is displayed on the segment type display tube 232. If there are a plurality of set values, they are displayed side by side as shown in FIG. 4D (96). Since the numbers at the two locations are different, the difference in the setting values is easy to understand. There are many opportunities to display numerical values such as output, temperature, and time.

  In the segment type display tube, the number is divided into seven segments and displayed as a combination thereof, so that numbers from 0 to 9 can be displayed at the same position.

  Further, the segment type display tube can be reduced in cost as compared with the case of displaying by the dot matrix type. Therefore, by using a segment-type display tube for the numerical display, it is possible to realize a display that can simultaneously confirm the menu name, setting contents, and setting values at a low cost.

  When heating is started by the input means 24, the display becomes as shown in FIG. The user can know the remaining heating time by changing the time display 97. Further, the total heating time and the elapsed time can be displayed on the dot matrix type display tube 231 as a graph 98 as shown in FIG. Thereby, the user can visually grasp the progress of heating.

  When heating is completed, the display is enlarged as shown in FIG. When the input means 24 is operated according to the operation instruction display 99, the heating time can be added.

  In the conventional heating device, notification is made by lighting or blinking of an illumination element provided near the input means 24, but it is difficult to convey the meaning to a user who does not know that such a function exists. If a dot matrix type display tube is used, it is possible to inform the user of the function and the operation method at the same time. When a certain time elapses without any operation, the display returns to the initial display (FIG. 4A).

  Next, the display transition of FIG. 5 will be described. When the input unit 24 is rotated to the right from the display state (FIG. 4A), the illumination element of the large classification name notation 92 of the display unit 235 is turned on, and the dot matrix type display tube 231 has the structure shown in FIG. A heating menu list belonging to the large classification name notation 92 is displayed as follows.

  When the input means 24 is further rotated to the right, the illumination elements are lit in the order of the major classification names 93 and 94, and the dot matrix type display tube 231 has the heating belonging to each as shown in FIGS. 5 (i) and 5 (j). The menu list is displayed in order. Manual heating menu list display The layout and design are changed from those in FIG. 4B to make it easy to distinguish between manual and automatic.

  Here, instead of the display unit 234 indicating the heating menu name, the display unit 235 indicating the general classification name of the automatic heating menu is required, but the heating menu list is displayed on the dot matrix type display unit 231. The size is small and the number of illumination elements can be reduced.

  When the major category to be selected is determined by the input means 24, the first heating menu of the major category is selected as shown (FIG. 5 (k)).

  From this, it can be seen that the menu selection is shifted from the large classification selection. When the input means 24 is rotated to the right, the selection menu changes in the rotation direction, and each menu is displayed in a selected state.

  When the user confirms the heating menu by the input means 24, the menu name is displayed in a large size on the dot matrix type display tube 231 as shown (FIG. 5 (l)). If there are accessories to be used for heating or items that need to be prepared in advance, display them. Accessories and preparations cause cooking to fail or cause cooking to be interrupted.

  Since the user wants to make a large display so as not to make a mistake, it displays it on the dot matrix type display tube 231 (101, 102). In addition, when an image is displayed together with characters, the dot matrix method is effective because the user can easily recognize what the user is pointing to.

  When heating is started by the input means 24, the display becomes as shown in FIG. The heating finish can be adjusted for a certain time after the start of heating. In the conventional heating device, notification is made by lighting or blinking of an illumination element provided near the input means 24, but it is difficult to convey the meaning to a user who does not know that such a function exists.

  Although it is not always necessary to operate, even a user who does not know that such a function is displayed on the dot matrix type display tube 231 as 103, and that the operation method is provided at the same time. I can inform you. When the period during which the finish can be changed is over, the display (FIG. 5 (n)) is displayed.

Further, the remaining time is displayed as shown in FIG. 5 (o) to inform the user of the remaining heating time. Further, the progress of heating can be displayed on the graph 98 as shown in (f). When the heating is completed, the display is enlarged as shown in FIG. 5 (g). Again, when the input means 24 is operated in accordance with the operation instruction display 99, the heating time can be added. When a certain time elapses without any operation, the display returns to the initial display (FIG. 4A).

  The detection means 26 includes a weight sensor and a temperature sensor. Thereby, information such as the weight of the object to be heated and the temperature of the heating chamber can be detected. When the current temperature detected during heating is displayed side by side with a set value on a segment type display tube, the user can know the heating status by comparing.

  There is also a method of using a graph for simultaneous display of the set value and the current value. The graph is displayed on a dot matrix display tube. There are one-dimensional and two-dimensional graphs, and they may be displayed either.

  As described above, the present invention can be applied to a heating device, can prevent a user's erroneous operation, and can improve operability.
