Hereinafter, one or more processors 130 are referred to as a processor 130.
The processor 130 may open a door 21 based on a user command. For the above, the oven 100 may include a motor to open the door 21.
Specifically, the processor 130, if the user command to open the door 21 is received, may drive the motor to open the door 21. Here, the user command may be inputted through a button (e.g. an auto door button) prepared on the input interface 190. Accordingly, the door 21 of the oven 100 may be automatically opened.
Meanwhile, the processor 130 identifies a risk level of the oven 100. Here, the risk level (or a risk grade) may be one of a plurality of risk levels.
For example, the plurality of risk levels may include a risk level from level 0 to level 5.
Here, the risk level 0 may mean a state in which the user is not in danger even if the door 21 is opened. Also, the risk level 1 may mean a state in which the user needs to be careful a bit if the door 21 is opened. Also, the risk level 2 may mean a state in which the user needs to be careful if the door 21 is opened. Also, the risk level 3 may mean a state in which the user may be in danger depending on a condition of the user (e.g. an age or a degree of proficiency of the user) if the door 21 is opened. Also, the risk level 4 may mean a state in which most users may be in danger of having an accident if the door 21 is opened. Also, the risk level 5 may mean a state in which the user may be exposed to serious danger if the door 21 is opened because a temperature in the oven 100 is so high, so that the door 21 should never be opened.
As the above, the risk level may mean that a degree of danger, which the user may run into due to opening of the door 21 is divided according to a stage. Meanwhile, in the aforementioned example, the description is made such that the risk level is divided into 6 stages. Meanwhile, the risk level may be divided into more than or fewer than 6 levels.
Specifically, the processor 130 identifies a risk level of the oven corresponding to a cooking state of the oven 100 and a temperature in the cooking chamber 20 detected through the temperature sensor 110 based on risk information stored in the memory 120.
For the above, the processor 130 may obtain a temperature in the cooking chamber 20 detected by the temperature sensor 110.
Also, the processor 130 may identify a cooking state of the oven 100. Here, the cooking state of the oven 100 may mean an operation state of the oven 100 related to cooking of a cooking material. For example, the cooking state of the oven 100 may be one of “before cooking”, “during preheating”, “during cooking”, and “after cooking completion”.
Specifically, the oven 100 may include a plurality of modes. The plurality of modes may include a manual mode and an auto mode.
The manual mode may mean a mode for performing cooking according to a cooking temperature, a cooking time, and a cooking mode (e.g. the cooking mode may include a direct fired oven, an oven, an air fryer, a grill, or the like, wherein as an example, according to the cooking mode, at least one of whether to drive a pan, a direction in which air flows in the cooking chamber 20, or a rotation speed of the pan may be determined) set by a user command.
For example, the user may set a cooking temperature, a cooking time, and a cooking mode through the input interface 190 and may select a start button. In this case, the processor 130 may drive a heater and a pan to heat a cooking material according the cooking temperature and the cooking mode set by the user command and provide hot air to the cooking material, thereby performing cooking during the cooking time set by the user command. Further, the processor 130 may stop driving the heater and pan and complete cooking if the cooking time is elapsed.
The auto mode may mean a mode that the oven 100 automatically sets a cooking temperature, a cooking time, and a cooking mode and performs cooking. Specifically, the auto mode may include a plurality of recipe modes. Further, the memory 120 may store information about a preset cooking temperature, cooking time, and cooking mode with respect to each recipe mode.
For example, the user may select one among a plurality of recipe modes through the input interface 190 after putting ingredients of food prepared according to a recipe to the cooking chamber 20. In this case, the processor 130 may identify a cooking temperature, a cooking time, and a cooking mode corresponding to a recipe mode selected according to the user command by using information about a cooking temperature, a cooking time, and a cooking mode for each of the plurality of recipe modes stored in the memory 120. Further, the processor 130 may drive a heater and a pan to heat a cooking material according to the identified cooking temperature and the identified cooking mode and provide hot air to the cooking material, thereby performing cooking during the identified cooking time. Further, the processor 130 may stop driving the heater and pan and complete cooking if the cooking time is elapsed. Meanwhile, the processor 130 may determine a cooking state of the oven 100.
For example, the processor 130, if a user command to select a cooking start and a recipe mode is not inputted, may identify a cooking state of the oven 100 as “before cooking”.
Also, the processor 130, if a time section is in a time section from a time point when a user input to select a cooking start or a recipe mode is inputted to the oven 100 to a time point when a temperature in the cooking chamber 20 arrives at a preset temperature or a time point when a preset time is elapsed, may identify a cooking state of the oven 100 as “during preheating”.
Here, in the case of the manual mode, the preset temperature and the preset time may be set to be determined based on a cooking temperature and a cooking time inputted by the user command. In the case of the auto mode, the preset temperature and the preset time may be set to be determined based on a cooking temperature and a cooking time corresponding to a recipe mode.
Also, the processor 130, if the time section is in a time section from a time point when preheating is completed to a time point when cooking is completed, may identify a cooking state of the oven 100 as “during cooking”.
Also, the processor 130, if the cooking time is elapsed and the cooking is completed, may identify a cooking state of the oven 100 as “after cooking completion”.
Further, the processor 130 identifies a risk level of the oven 100 corresponding to a cooking state of the oven 100 and a temperature in the cooking chamber 20 based on risk information stored in the memory 120.
For the above, the memory 120 may store risk information. Here, the risk information may include information about a risk level at each of a plurality of temperatures for each of a plurality of cooking states.
In this case, the memory 120 may store a plurality of risk information for the manual mode and a plurality of risk information for the auto mode.
The plurality of risk information for the manual mode may correspond to a plurality of cooking modes. That is, risk information corresponding to each cooking mode may be stored in the memory 120.
For example, as shown in 3A, risk information 310 corresponding to cooking mode 1 and risk information 320 corresponding to cooking mode 2 may be stored. As shown in 3A, risk information 310, 320 may include information about a risk level according to a temperature in the cooking chamber 20 in each cooking state when the cooking state of the oven 100 corresponds to each of “before cooking”, “during preheating”, “during cooking”, and “after cooking completion”. Meanwhile, it is described in
The processor 130 may identify a recipe mode selected according to a user command among a plurality of recipe modes and identify a risk level corresponding to a cooking state of the oven 100 and a temperature in the cooking chamber 20 detected through the temperature sensor 110 based on risk information corresponding to the identified recipe mode.
That is, in the case of the manual mode, the cooking mode may be selected according to the user command. In this case, the processor 130 may identify risk information corresponding to a cooking mode selected according to a user command among the plurality of risk information for the manual mode stored in the memory 120 and identify a risk level corresponding to a cooking state of the oven 100 and a temperature in the cooking chamber 20 among risk levels at each of a plurality of temperatures for each of a plurality of cooking states based on risk information.
For example, it is assumed that the cooking mode selected according to the user command is in the cooking mode 2, the oven 100 is in a state of preheating, and a temperature in the cooking chamber 20 detected by the temperature sensor 110 is 95° C. In this case, with reference to
A plurality of risk information for the auto mode may correspond to a plurality of recipe modes. That is, risk information corresponding to each recipe mode may be stored in the memory 120.
For example, as shown in 3B, risk information 330 corresponding to recipe mode 1 and risk information 340 corresponding to recipe mode 2 may be stored. As shown in
The processor 130 may identify a recipe mode selected according to a user command among a plurality of recipe modes and identify a risk level corresponding to a cooking state of the oven 100 and a temperature in the cooking chamber 20 detected through the temperature sensor 110 based on risk information corresponding to the recipe mode.
That is, in the case of the auto mode, the recipe mode may be selected according to the user command. In this case, the processor 130 may identify risk information corresponding to a recipe mode selected according to a user command among the plurality of risk information for the auto mode stored in the memory 120 and identify a risk level corresponding to a cooking state of the oven 100 and a temperature in the cooking chamber 20 among risk levels at each of a plurality of temperatures for each of a plurality of cooking states based on risk information.
For example, it is assumed that the cooking mode selected according to the user command is in the recipe mode 1, the oven 100 is in a state of “after cooking completion”, and a temperature in the cooking chamber 20 detected by the temperature sensor 110 is 355° C. In this case, with reference to
Meanwhile, the processor 130 controls an opening operation of the door 21 of the oven 100 based on the risk level of the oven 100.
Specifically, the processor 130, if the user command to open the door 21 is received through the input interface 190, may open the door 21. Here, the user command may be inputted through a button (e.g. an auto door button) prepared on the input interface 190.
Here, the processor 130 may control an opening operation of the door 21 of the oven 100 based on the risk level of the oven 100. In this case, a speed at which the door 21 is opened and a degree to which the door 21 is opened may be determined based on the risk level.
Specifically, the processor 130 may identify an opening speed of the door 21 and an opening degree of the door 21 corresponding to a risk level of the oven 100 among opening speeds of the door 21 and opening degrees of the door 21 corresponding to each of a plurality of risk levels. Further, the processor 130 may open the door 21 according to the identified opening speed and opening degree.
Further, information about an opening speed and an opening degree of the door 21 corresponding to each of the plurality of risk levels may be stored in the memory 120. Accordingly, the processor 130 may identify an opening speed and an opening degree of the door 21 corresponding to a risk level of the oven 100 among the plurality of risk levels by using information stored in the memory 120. Further, the processor 130 may control an opening speed and an opening degree of the door 21 by using a motor.
Specifically, the processor 130, if the risk level of the oven 100 is in a first level among the plurality of risk levels, may open the door 21 at a first speed. Further, the processor 130, if the risk level of the oven 100 is in a second risk level higher than the first risk level among the plurality of risk levels, may open the door 21 at a second speed lower than the first speed.
Here, the first risk level may be a low risk level among the plurality of risk levels. For example, the first risk level may be the risk level 0 and the risk level 1. Further, the second risk level may be an intermediate risk level among the plurality of risk levels. For example, the second risk level may be the risk level 2 and the risk level 3.
Accordingly, with reference to 410 of
Also, the processor 130, if the risk level of the oven 100 is in a third risk level higher than the second risk level among the plurality of risk levels, may open the door 21 only partially.
Here, the third risk level is a high risk level among the plurality of risk levels. For example, the third risk level may be the risk level 4.
For example, with reference to 430 of
That is, the door 21 may open and close the cooking chamber 20 in a method that an upper part of the door 21 rotates around a lower part of the door 21. Here, a state that the door 21 is completely opened may mean a state that the door 21 rotates approximately 90 (=θ1) degrees with respect to a state that door 21 is closed. Meanwhile, even if the user manually opens the door 21, the door 21 may be completely opened. Meanwhile, this is an example, and an angle by which the door 21 rotates when the door 21 is completely opened may be set in a process of manufacturing the oven 100.
Meanwhile, with reference to 440 of
That is, if the risk level of the oven 100 is high, the door 21 rotates by a preset angle and is positioned to be inclined with respect to a virtual plane corresponding to a front surface of the cooking chamber 20. In this regard, the cooking chamber 20 is not completely opened by the door 21.
Also, the processor 130, if the risk level of the oven 100 is in a fourth risk level higher than the third risk level among the plurality of risk levels, may not open the door 21.
Here, the fourth risk level is the highest risk level among the plurality of risk levels. For example, the fourth risk level may be the risk level 5.
That is, if a risk level of the oven 100 is the highest, even though a user command to open the door 21 is inputted, the door 21 may not be opened and be maintained in a closed state.
Meanwhile, the oven 100 may include a light emitting element. Here, the light emitting element may emit light having a plurality of colors. For example, the light emitting element may be a LED lamp.
The processor 130 may control the light emitting element to emit a color corresponding to a risk level of the oven 100 among a plurality of different colors corresponding to the plurality of risk levels.
For example, the processor 130 may control the light emitting element to emit white light if the risk level of the oven 100 is in the risk level 0. Also, the processor 130 may control the light emitting element to emit yellow light if the risk level of the oven 100 is in the risk level 1. Also, the processor 130 may control the light emitting element to emit slight orange light if the risk level of the oven 100 is in the risk level 2. Also, the processor 130 may control the light emitting element to emit orange light if the risk level of the oven 100 is in the risk level 3. Also, the processor 130 may control the light emitting element to emit slight red light if the risk level of the oven 100 is in the risk level 4. Also, the processor 130 may control the light emitting element to emit red light if the risk level of the oven 100 is in the risk level 5.
Meanwhile, light emitted by the light emitting element may be displayed on door glass of the door 21. The door glass may have a rectangular shape and may be implemented as a glass material. The light emitting element may be positioned at a lower part of the door glass such that light emitted from the light emitting element is directed to the door glass. Accordingly, a color of light emitted by the light emitting element may be displayed on the door glass.
For example, as shown in
Meanwhile, the oven 100 may include a speaker. In this case, the processor 130, if the risk level of the oven 100 is equal to or greater than a preset risk level, may output sound through the speaker.
Here, the preset risk level is the highest risk level among the plurality of risk levels. For example, the preset risk level may be the risk level 4.
As shown in 610 of
As above, the oven 100 may determine a risk level of the oven 100 based on a cooking state of the oven 100 and a temperature in the cooking chamber 20. Further, the oven 100, when automatically opening the door 21, may open the door 21 at a slow speed, open it only partially, or not open it based on the risk level of the oven 100. Also, the oven 100 may output at least one of light having a specific color or sound according to the risk level of the oven 100.
For example, if a cooking material is being cooked in the oven 100, there is a risk that a safety accident occurs to the user due to a dangerous element (e.g. hot oil, etc.) incurred from the cooking material depending on a high temperature inside the oven, a type of material, and the like, but the user may approximately recognize this risk because the oven 100 is driven. However, after the cooking is completed, the user may not recognize this risk because the oven 100 is not driven even though there is no cooking material in the oven 100 and a temperature inside the oven is still high. However, there are many cases that the user wants to open the door and directly confirm the cooking material during cooking or after cooking completion.
Therefore, the oven 100 of the disclosure determines a risk level based on a cooking state of the oven 100 and a temperature in the cooking chamber 20, controls an opening operation of the door 21 according to the risk level, and provides a notification to the user. Accordingly, an accident which may occur to the user under various circumstances may be prevented.
Also, the oven 100 may photograph the cooking chamber 20 according to a risk level of the oven 100 and may output sound based on an image in which the cooking chamber 20 is photographed.
