Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a toaster for providing bread patterns,

The present invention relates to a toaster (TOASTER), and more particularly, by spraying a juice solution onto a predetermined picture panel, and by installing the picture panel and the bread in close proximity to perform the bread baking, the figure is shown on the surface of the bread It relates to a toaster for providing a bread pattern to make.

Generally, a toaster is a device that supplies electricity to generate heat from the heater, and the heat generated from the heater is used to cook the toast by baking the bread. Toast is prepared as a snack for those who replace the breakfast with bread and milk Is often used.

The toaster includes a hole through which the bread can be inserted, and a lever which can move the inserted bread to the lower side of the toaster. On the inner side of the hole into which the bread is inserted, And a bread crumb tray for preventing the bread crumb from being dropped into the toaster is provided at a lower portion where the bread crumb is baked after the moved bread crumb can be baked.

In addition, the toaster described above has at least two feed ports for feeding bread into the main body, and a heater for simultaneously heating both sides of the bread is provided on the side of each feed port. Therefore, when the user sets the driving time of the heater by the timer and then pushes the eject lever to feed the bread into the feeding port, the heater is driven by the built-in heating circuit for the timer set time, It stops and the bread is discharged.

Recently, commercial toasters have given functionality according to the changes of the times, and they are increasing the selling rate by the functionality. The functionalities of the toaster have been variously developed. For example, in the process of grilling the toaster, a pattern is arbitrarily drawn on the outer surface of the bread to increase the appeal of the child. In the toaster in which the pattern is drawn, a predetermined pattern panel is inserted between the bread and the heater so that the pattern is shown at the position of the bread that faces the pattern panel in the heating process of the heater.

However, such a pattern panel prevents the toaster heater from generating heat, and the material thereof is made of a metal material. When the bread is in contact with the metal material, it is harmful to the human body. Furthermore, when the metal material is heated, There is a problem that can act as.

Then, the above-described conventional toaster will be described with reference to the prior art document.

Republic of Korea Utility Model 20-0179556 is known as a 'toaster that appears a variety of grilled pattern', which is a toaster of the additional function that can be used to shape any pattern on the outer skin of the bread using a toaster, described with reference to FIG. Is as follows.

First, as shown, the non-heating roasting control frame is configured to slide on the fixed part in front of the coil part (heating part) of the toaster, and the roasting control frame heat transfers only the non-heating part in which the symmetrical model appears in the coil part (heating part). By preventing the appearance of a certain shape.

In addition, the unheated portion of the grill control frame is made centered around the grill so that the bread is appropriately baked, and various grill control frames can be changed according to preference. For example, if you put bread in a toaster and heat it, after a certain period of time, the properly baked bread is discharged and various shapes and characters appear on the bread.

Therefore, after the bread is baked, various pictures and phrases are displayed, so the pleasure of the meal is multiplied and the grill control frame with pictures and phrases suitable for each age group is inserted and replaced, .

However, as described above, the conventional toaster inserts an arbitrary pattern into the surface of the bread by the non-heating portion formed in the roasting control frame, so that the heating heat of the heater does not touch the opposed position of the non-heating portion and the bread portion . Therefore, the non-heating portion of the heater and the non-heating portion of the roasting control frame perform the opposite purpose, resulting in a problem that the heating energy of the heater is unnecessarily wasted.

That is, since the heat energy for heating the bread through the heater reflects the heat energy by the non-heating portion of the roasting control frame, efficient management of the energy can not be achieved. In addition, since the non-heating portion of the roasting control frame reverses the heating energy of the heater, the heating energy is again radiated to the heater. This means that the heater, which consumes the rated current, may heat up beyond the reference value due to the reflected heat, thus creating a risk of fire.

As a result, a stable system for injecting arbitrary patterns into the surface of the bread is required, and the development of a system capable of minimizing unnecessary waste of energy is urgently needed.

As shown in the figure, a cooking cavity 211 for cooking bread is provided on a front surface of the cooking cavity 211, and an operation switch 205 for cooking the grill and a cooking cavity 211 The cooking cavity 221 is provided with a door 221 for opening and closing the cooking cavity 211. The cooking cavity 221 is provided with a cooking cavity insertion groove 203 in which a cooking cavity 251 for drawing an arbitrary figure on the outer surface of the bread is inserted, And a feed link 213 for mounting the paint board 251 on the outer surface of the bread in response to an operation signal of the operation switch 205 is mounted on both sides of the cooking cavity 211, A juice ejection nozzle 215 for ejecting juice liquid from the rear part of the cooking cavity 211 and the juice ejection nozzle 215 for ejecting the juice liquid from the cooking cavity 251 to the cooking cavity 251, Including a control device for ejection control of juice .

Meanwhile, the paint plate 251 may include a transparent portion 253 corresponding to an arbitrary shape so that the fruit juice may be penetrated into the outer surface of the bread, and a portion of the juice permeable to the outer surface of the white bread And a non-transmissive portion 255 for blocking the jetting portion from being sprayed.

The transparent portion 253 of the paint plate 251 may be made of a fiber or metal having a mesh structure for liquid permeation and the non-transparent portion 255 may be made of a material such as plastic, metal, wood, Do. If necessary, the paint plate 251 may be formed of a metal panel, and the transmissive portion 253 may be formed to have an arbitrary shape.

In addition, the juice solution can be selected according to the user's taste, and in the embodiment of the present invention, lemon juice solution is used. The use of such a juice liquid is intended to cause the juice of the juice to be dissipated during the bread baking due to the juice, and to promote juice flavor and taste in the drinking process. Therefore, it is natural that any fruit juice other than the lemon juice may be used as the juice.

One end of the housing 201 is provided with a juice inserting cap 207 for inserting the juice solution, and a viewing window 209 for visually monitoring the remaining amount of the juice solution is provided. The unshown handle 223 is for opening and closing the door 221 and has a locking and unlocking function of the door 221.

The conveying link 213 is an X-shaped link structure for vertically conveying the printing plate 251 vertically and controls the vertical movement of one of the link bars at the lower end of the link to control the vertical movement of the printing plate 251. The conveyance link 213 may be a rack pinion structure, a quadruple link, a screw type, a conveying system using a wire, or the like as a means for vertically conveying the Paint Plate 251 as an embodiment of the present invention. Therefore, the operation of the conveyance link 213 can be applied in a plurality of ways.

The toaster 200 of the present invention configured as described above first opens the door 221 using the handle 223 and then places the bread in the cooking space 211. Thereafter, the door 221 is closed and an optional plate 251 is inserted into the plate insertion groove 203. A plurality of types of the paintbrushes 251 may be provided depending on the pattern, and one of the paintbrushes 251 may be inserted into the paintbrush insert groove 203 according to the user's selection.

Then, the user closes the door 221 and uses the operation switch 205 to start the graphic of the paintbrush 251 to be drawn on the outer surface of the bread. Accordingly, the paintbrush 251 is conveyed downward by the conveyance link 213, and the paintbrush 251 is pressed onto the envelope of the bread. In the downward transfer of the Paintbrush 251, the internal controller detects whether the Paintbrush is brought into close contact with the envelope of the bread by detecting the conveyance load of the Paintbrush. Of course, a separate sensor can be used to judge whether the plate and the bread are in close contact.

When the paint plate 251 is brought into close contact with the outer surface of the bread, the juice ejection nozzle 215 ejects the primed juice onto the paint plate 251 under the direction of the controller. Therefore, the juice is sprayed onto the outer surface of the bread through the transmission part 253 of the paint board 251, and the outer surface of the bread absorbs the juice corresponding to the pattern of the transmission part 253.

The spraying time of the juice solution is preferably about 2 seconds to 4 seconds based on the experimental basis, and it may vary depending on the thickness of the bread and the injection amount of the juice. In this manner, when juice injection is completed, the controller operates the feed link 213 to perform a reset control so that the paint board 251 is fed upward.

When the paintbrush 251 reaches the initial position, the controller outputs a warning message to guide the paintbrush 251 to be drawn out from the paintbrush insert groove 203. When the paintbrush 251 is drawn out from the paintbrush insert groove 203, the controller performs a grill operation, which is a unique function of the toaster 200. Therefore, by grilling operation of the toaster 200, the remaining portion excluding the adsorption site of juice adsorbed onto the envelope of the bread is heated and cooked. Of course, the adsorption site of the juice may also be cooked, but the cooked portion may have a brightness difference due to heating, so that an arbitrary pattern is displayed on the bread crust.

3 is a perspective view illustrating the main mechanism of the present invention.

A mounting frame 301 having one end open to insert the paintbrush 251 and having a U-shaped insertion guide 303 is installed on each side of the mounting frame 301, A floating link 321 for vertically moving the seat frame 301 and a driving cylinder 323 for driving the floating link 321 are provided.

One end of the two end portions is coupled to the housing 201 through a fixed hinge 327 and the other end is connected to the driving cylinder 323 do. Accordingly, the operation of the drive cylinder 323 actuates the other end of the flow link 321 on the horizontal line, from which the seat frame 301 fastened to the flow link 321 flows up and down.

The juice ejection nozzle 215 is connected to a pump 333 for pumping juice through a pipeline 335 and the pump 333 is connected to a juice loading box 331 for loading the juice do. The juice storage box 331 is made of a transparent material so that the amount of juice loaded in the juice storage box 331 can be recognized through the viewing window 209.

The seat frame 301 includes a switch 311 for determining whether a paint board 251 is installed according to the insertion guide 303. The switch 311 is connected to a limit switch, A photocoupler or the like may be applied. In addition, the juice ejection nozzle 215 is located within the transportable section of the seating frame 301, and preferably the middle position of the transportable section is appropriate.

5 is an electrical schematic diagram illustrating the main operation of the present invention.

A grill heater 503 installed in upper and lower portions of the cooking space 211, a cylinder motor M for operating the driving cylinder 323, a pump motor (not shown) for operating the pump 333, A relay module 509 for switching control of the grill heater 503, the cylinder motor M and the pump motor P, and a control unit 509 for controlling the amount of current consumption of the cylinder motor M And a message output unit 513 for outputting an error message or an operation guidance message. In response to the instruction of the operation switch 205, the pattern of the picture board 251 is displayed on the outer surface of the white bread, And a controller 501 for starting the grill heater 503 to perform baking of the bread.

The controller 501 determines whether or not the switch 311 is retracted from the switch 311 to the setting position of the paint board 251 and then uses the cylinder motor M So that the pump motor P starts to operate to spray control juice of a predetermined volume.

The controller 501 recognizes that the pattern drawing process is completed and then transfers the seat frame 301 to an initial position and uses the message output unit 513 to cause the paint board 251 to insert the paint board After guiding to be discharged from the groove 203, the grill heater 503 is operated to perform the grill cooking.

The ADC 511 is for measuring the amount of current supplied to the cylinder motor M as a digital signal and determines the overload state of the cylinder motor M. [ Here, the overload state of the cylinder motor M recognizes the overload state, recognizes the overload pattern, and recognizes whether the overload state continuously increases from the time when the overload occurs, or when the overload state occurs, And whether or not an overload state occurs.

Therefore, it is determined whether the bread is present in the cooking space 211 from the overload state detected by the ADC 511, and whether the seating frame 301 has reached the initial position.

Hereinafter, the operation of the present invention will be described in detail.

When the paint board 251 is drawn into the insertion guide 303 of the mounting frame 301, the controller 501 recognizes the insertion state of the paint board by the switch 311 located on the mounting frame 301 do. When the cylinder motor M of the drive cylinder 323 is operated by the controller 501, the drive cylinder 323 presses the other end of the flow link 321 outward, The seat frame 301 is transported downward by the link structure.

At this time, the controller 501 recognizes the overload state of the driving cylinder 323, and measures the amount of current supplied to the cylinder motor M through the ADC 511. The controller 501 detects the amount of current supplied from the cylinder motor M from the ADC 511 into a digital signal and detects a change in the amount of current consumption of the cylinder motor M from this. For example, the loading state of the driving cylinder 323, which is generated when the seating frame 301 is brought into close contact with the bottom surface of the cooking space 211, and the load state of the driving cylinder 323 generated when the inside frame 301 is seated on the top surface of the bread 323 are overloaded.

In the first case, the overload by the physical mechanism of the floating link is to detect that the load is excessive at a certain point in time, and in the second case it is to detect the condition that the overload gradually increases. For example, the overload of the driving cylinder 323 starts to occur at the time when the paint plate is pressed onto the envelope of the bread, and an exponential overload state occurs over time. The controller determines whether the bread is present in the cooking space 211 based on the overload state of the driving cylinder 323. [

On the other hand, when no bread is present in the cooking space 211, the driving cylinder 323 operates in a no-load state for a predetermined period, and an unexpected overload occurs at the moment when the bottom surface of the cooking chamber 301 and the seating frame 301 are in close contact with each other do. Therefore, through the overload determination, it is recognized that the bread is not present in the cooking space 211.

The controller controls the driving cylinder 323 to be moved upward to an initial state when no bread is present on the bottom surface of the cooking space 211 based on the determination of the controller 501, 513 to output an error message.

When the breadboard 251 is not inserted into the insertion guide 303 of the seating frame 301 and the bread is not present on the bottom surface of the cooking cavity 211, The seating frame 301 is brought into close contact with the bottom surface of the cooking cavity 211 due to the seating space 305 formed at the center of the cooking cavity 211, Therefore, in this case, the same error message is output and the system is initialized.

On the other hand, when it is determined that the bread is present on the bottom surface of the cooking space 211 based on the judgment of the controller 501, the controller 501 stops the cylinder motor M, The operation of the pump motor P of the pump 333 is controlled so as to supply the juice such as lemon juice accumulated in the juice storage box 331 to the juice discharge nozzle 215. [ The operation of the pump 333 sucks the juice and then supplies the juice to the juice discharge nozzle 215 along the pipe 335. The juice discharge nozzle 215 is connected to the upper end of the juice extracting nozzle 215, .

The juice ejection nozzle 215 may be composed of a plurality of nozzles to widen the jetting range of the juice. The controller 501 stops the operation of the pump 333 by recognizing the lapse of the predetermined pump driving time and then controls the driving cylinder 323 so that the mounting frame 301 is transported upward Indicate.

In the course of upward movement of the seat frame 301, the controller detects an overload state of the driving cylinder 323 and recognizes the initial position of the seat frame 301 based on the detected overload state. Then, when the controller recognizes that the seat frame 301 is present at the initial position, the controller outputs a message to eject the paintbrush 251 from the paintbrush insert groove 203. The message may be a voice guidance message, a text message via an LCD display panel or an alarm sound using a piezo.

Accordingly, when the paintbrush 251 is drawn from the user, the controller 501 supplies the rated power to the grill heater 503 in order to perform grilling by the operation of the toaster 200. So that an arbitrary pattern is displayed on the envelope of the bread in the roasting process due to the operation of the grill heater 503. 4, after the juice is injected onto the outer surface of the bread through the pattern formed on the paint plate 251, when the grilling operation is performed, the remaining portion excluding the juice absorbed portion is preferentially roasted Whereby an arbitrary pattern is shown on the envelope of the bread.

When the controller 501 recognizes that the cooking is completed for a predetermined time, the controller 501 notifies the user that cooking is completed using the message output unit 513.
