Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a microwave oven and a heating method thereof. Background Art

[0002] Currently, the most commonly used household appliance for quickly heating food is the microwave oven. Microwave ovens heat food by emitting microwaves. Microwaves can penetrate a certain thickness inside the food, causing the water molecules in the food to move. The water molecules will generate a large amount of heat energy during the movement, which can be used to heat the food.

[0003] Microwave ovens have a high heating efficiency when used to heat smaller foods, but when used to heat larger foods, the heating efficiency is greatly reduced, and as the heating time increases, the food tends to harden due to evaporation of water, which greatly reduces the taste of the food. Therefore, how to propose a heating device that can improve the heating efficiency of food and have less impact on the taste of food is a technical problem that needs to be solved urgently. Summary of the invention

[0004] The first object of the present invention is to provide a microwave oven that heats food quickly and can basically maintain the taste of the food.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] A microwave oven comprises: an inner pot having a heating space for placing food; an electric heating assembly, the electric heating assembly comprising at least one heating tube, the heating tube being arranged on the inner wall of the inner pot; a microwave heating assembly, the microwave heating assembly being arranged on the inner pot and used for emitting microwaves into the heating space; a fan assembly, the fan assembly being arranged on the inner pot and used for forming hot air in the heating space and blowing toward the surface of food; and a detection mechanism, the detection mechanism being arranged in the inner pot and used for detecting the maturity of food.

[0007] Preferably, the heating tube includes a top heating tube, a back heating tube and a bottom heating tube, the top heating tube is arranged on the top surface of the heating space formed in the inner pot, the back heating tube is arranged on the rear wall surface of the heating space formed in the inner pot, and the bottom heating tube is arranged on the bottom surface of the heating space formed in the inner pot.

[0008] Preferably, the detection mechanism includes a color identifier, and determines the maturity by detecting the color of the food surface; or, the detection mechanism includes a temperature detection element, and determines the maturity by detecting the length of time the food surface maintains a target temperature.

[0009] The second object of the present invention is to provide a heating method for a microwave oven, which can increase the heating speed of food and basically maintain the taste of food.

[0010] To achieve this object, the present invention adopts the following technical solutions:

[0011] A heating method for a microwave oven is used for the above-mentioned microwave oven, wherein the microwave oven includes a combined heating mode, and the heating method for the microwave oven includes the following steps:

[0012] To activate combined heating mode:

[0013] S1, starting the electric heating component to electrically heat the food from the outside to the inside;

[0014] S2, after the electric heating component continues to heat the food for a first preset time, using a detection mechanism to detect the maturity of the food, and determining whether the maturity of the food reaches a first target value;

[0015] If the maturity of the food reaches the first target value, it means that the food is basically mature;

[0016] If the maturity of the food does not reach the first target value, proceed to S3;

[0017] S3, starting the microwave heating component to perform microwave heating on the food from the inside out;

[0018] S4. Start the fan assembly to blow hot air onto the surface of the food.

[0019] Preferably, after step S3, the following steps are also included:

[0020] S31, after starting the microwave heating component for a second preset time, using a microwave leakage meter to detect the amount of microwaves emitted by the microwave heating component;

[0021] If the amount of microwaves detected by the microwave leakage instrument is less than the amount of microwaves emitted by the microwave heating component, the alarm system of the microwave oven is activated to give an alarm and the microwave oven is controlled to stop;

[0022] If the amount of microwaves detected by the microwave leakage instrument is equal to the amount of microwaves emitted by the microwave heating component, the microwave heating component continues to work.

[0023] Preferably, after determining that the microwave heating component can continue to work, the method further includes the following steps:

[0024] S32, at every third preset time interval, using the detection mechanism to detect the maturity of the food, and determining whether the maturity of the food reaches a second target value, wherein the second target value is not less than the first target value and not greater than 100%;

[0025] If the maturity of the food reaches the second target value, proceed to S4;

[0026] If the maturity of the food does not reach the second target value, the microwave heating component continues to perform microwave heating on the food.

[0027] Preferably, the detection mechanism is set to detect the maturity of food n times every the third preset time period. If the maturity of food is still less than the second target value after the last detection, the heating power of the microwave heating component is increased and S32 is repeated.

[0028] Preferably, in step S4, while starting the fan assembly to blow hot air to the food surface, the countdown mechanism of the microwave oven is started and the fourth preset time is set. After the fourth preset time is over, the fan assembly is turned off.

[0029] Preferably, in step S3, the electric heating component is turned off while the microwave heating component is started to perform microwave heating on the food from the inside out;

The microwave oven can combine the electric heating component, the microwave heating component and the fan component to heat the food, thereby improving the heating efficiency of the food as a whole, and since the microwave heating component will not be used for a long time, the taste of the food will not be greatly reduced.

[0035] The heating method of the microwave oven provided by the present invention has a combined heating mode. In the combined heating mode, for food that is large and difficult to heat, the electric heating component, the microwave heating component and the fan component can be used in sequence to heat the food, so that the heating efficiency of the food is effectively improved, and the long-term use of the microwave heating component to heat the food is avoided, thereby ensuring the taste of the food. The maturity of the food is detected by the detection mechanism, so that the method determines whether to perform electric heating alone or a combination of electric heating and microwave heating by judging the maturity of the food, thereby realizing intelligent heating of the food.

[0047] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0049] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] The present invention provides a microwave oven that can heat food in combination, and is particularly suitable for rapidly heating large volumes of food. Figure 1 and Figure 2 As shown, the microwave oven includes a housing 400, an inner pot 100, an electric heating assembly 200, a microwave heating assembly 300, a fan assembly and a detection mechanism. The housing 400 forms an installation space, the inner pot 100 is arranged in the housing 400, and the inner pot 100 has a heating space for placing food. In some embodiments, the housing 400 and the inner pot 100 are roughly cubic. The electric heating assembly 200 includes at least one heating tube, which is arranged on the inner wall of the inner pot 100 and is used to electrically heat the food. The microwave heating assembly 300 is arranged on the inner pot 100 and is used to emit microwaves into the heating space. The fan assembly is arranged on the inner pot 100 and is used to form hot air in the heating space that blows toward the surface of the food. The detection mechanism is arranged in the inner pot 100 and is used to detect the maturity of the food.

[0051] Compared with the existing microwave ovens that can only perform microwave heating or heating boxes that can only perform electric heating, the microwave oven provided in the present application can utilize the electric heating component 200, the microwave heating component 300 and the fan component to perform combined heating of food. Since the electric heating performed by the electric heating component 200 heats the food from the outside to the inside, and the microwave heating component 300 heats the food from the inside to the outside, the hot air formed by the fan component in the inner pot 100 can make the temperature uniform throughout the heating space, thereby achieving uniform heating of the food. Not only is the heating efficiency of the food improved as a whole, but also since the microwave heating component 300 will not be used for a long time, the taste of the food will not be significantly reduced, thereby improving the user experience.

[0052] In some embodiments, the heating tube includes a top heating tube, a back heating tube and a bottom heating tube. The top heating tube is arranged on the top surface of the inner pot 100 forming a heating space, the back heating tube is arranged on the rear wall surface of the inner pot 100 forming a heating space, and the bottom heating tube is arranged on the bottom surface of the inner pot 100 forming a heating space. The top heating tube, the back heating tube and the bottom heating tube are arranged around the food to achieve uniform electric heating of the food. As for the front of the inner pot 100, an opening for food to enter and exit the heating space is formed, and the left and right walls of the inner pot 100 forming the heating space can be formed with a support rod 500 for placing a tray. Of course, the electric heating assembly 200 also includes an electrical connector for connecting multiple heating tubes to electricity.

[0053] Furthermore, the top heating tube, the back heating tube and the bottom heating tube can be set as one or more according to the needs. If there are multiple heating tubes, the multiple heating tubes can be arranged in a circle or in rows and columns; of course, they can also be arranged in a ring structure, a serpentine structure or a mosquito coil structure. The shape of the heating tube can be a long strip or a sphere, and multiple spherical heating tubes can also be arranged in a lattice.

[0054] In some embodiments, the microwave heating assembly 300 is disposed on the top surface of the inner pot 100 forming the heating space. The microwave heating assembly 300 includes a frequency converter, a magnetron, a waveguide, etc. It should be noted that the specific structure and connection relationship of the microwave heating assembly 300 are all prior art, so they are not described in detail here.

[0055] Continue to refer to Figure 1 As shown, a main cooling air duct 600 and a microwave cooling air duct 700 are also provided on the top of the inner container 100, and the fan assembly can realize ventilation in the inner container 100 through the main cooling air duct 600 and the microwave cooling air duct 700. The specific structure of the fan assembly is prior art and will not be described in detail here.

[0056] In some embodiments, the detection mechanism is a maturity sensor, which includes a color identifier and determines maturity by detecting the color of the surface of the food. Specifically, since the food contains protein, the color of the protein changes after heating. The color identifier can identify the surface of the food and compare the color of the obtained food with a plurality of pre-stored pictures in the gallery representing different degrees of maturity of different foods, thereby obtaining the maturity of the food. The maturity here is a ratio, such as 30%, 50%, 90%, etc. It should be noted that the color identifier is integrated with a photographing mechanism and a graphic analysis mechanism, and the specific structure of the photographing mechanism and the graphic analysis mechanism is a prior art and will not be described in detail here.

[0057] The maturity sensor is generally arranged on the bottom surface of the inner tank 100 forming the heating space. In some other embodiments, the maturity sensor includes a temperature detection member, and the maturity is judged by detecting the length of time that the food surface maintains the target temperature. Specifically, the temperature detection member can perform multiple temperature detections on the surface of the food, thereby obtaining the temperature of the food surface. If the food surface can be maintained at the target temperature in multiple detections, the maturity of the food can be obtained using a temperature-maturity relationship chart, which is a pre-stored chart. Of course, the temperature probe can also be installed at the output end of the retractable mechanism, so that the temperature probe carrying the temperature detection member can be inserted into the food to detect the temperature inside the food. For example, the temperature-maturity relationship chart can obtain the maturity of the food, so that the judgment structure is more accurate. The retractable mechanism here can be any mechanism that can output linear motion in the prior art, and no specific restrictions are made here. Of course, the temperature probe can also be set on the movable mechanism, so that the temperature probe can detect different positions of the food, thereby further improving the accuracy of food temperature detection.

[0058] Based on the above-mentioned microwave oven, the present invention also provides a heating method for the microwave oven, which includes a combined heating mode, a single microwave heating mode, a single electric heating mode, an air heating mode and an air cooling mode. Users can choose to start different modes according to their needs.

[0059] For the above-mentioned single microwave heating mode, the microwave oven and oven independently starts the microwave heating component 300, and at this time the microwave oven and oven is equivalent to a microwave oven.

[0060] For the above-mentioned single electric heating mode, the microwave oven and oven independently starts the electric heating component 200. At this time, the microwave oven and oven is equivalent to a heating box capable of electric heating.

[0061] For the air-heating mode, the microwave oven starts the fan assembly and the electric heating assembly 200 at the same time, and the microwave oven is equivalent to a fan that can blow hot air. For the air-cooling mode, the microwave oven starts the fan assembly alone, and the microwave oven is equivalent to a fan that can blow natural wind. Since the microwave oven is generally placed in the kitchen, the ability of the microwave oven to blow hot air or natural wind can improve the kitchen environment and enhance the user experience.

[0062] For combined heating modes, such as Figure 3 As shown, the heating method of the microwave oven comprises the following steps:

[0063] S1. Start the electric heating component 200 to electrically heat the food from the outside to the inside.

[0064] S2. After the electric heating component 200 continues to heat the food for a first preset time, a detection mechanism is used to detect the maturity of the food and determine whether the maturity of the food reaches a first target value.

[0065] If the maturity of the food reaches the first target value, it means that the food is basically mature; at this time, according to the needs of the user, the microwave oven can be directly shut down, and the user can take out the food for use, or directly proceed to S4 to further heat the food.

[0066] If the maturity of the food does not reach the first target value, proceed to S3.

[0067] S3, start the microwave heating assembly 300 to perform microwave heating on the food from the inside out.

[0068] S4. Start the fan assembly to blow hot air onto the surface of the food.

[0069] In some embodiments, the first preset time length can be set to 15 minutes. Of course, in some other embodiments, the first preset time length can be set to 5 minutes, 10 minutes or 20 minutes. It should be noted that the setting of the first preset time length is set according to the weight and type of food. For the same kind of food, the greater the weight, the longer the first preset time length is set. The weight and the first preset time length are inverse tangent functions: T1=A1arctanM, where T1 represents the first preset time length, M represents the weight of the food, and A1 is an integer set according to the type of food. In the embodiments of the present application, the specific value of A1 is not limited and is obtained based on experiments.

[0070] In some embodiments, the first target value is set to 90%. Of course, in other embodiments, the first target value may also be set to 80% or 70%.

[0071] In order to measure the weight of the food, the following steps are also included before step S2:

[0072] The food is fuzzily weighed, and a first preset time and a first target value are set according to the result of the fuzzy weighing.

[0073] It should be noted that the microwave oven includes a tray for placing food, and a weighing mechanism for implementing fuzzy weighing is provided on the tray. The specific method of fuzzy weighing is a prior art and will not be described in detail here.

[0074] Of course, in addition to controlling the first preset time by detecting the weight of the food, the first preset time can also be controlled by detecting the volume of the food. The measuring mechanism for measuring the volume of food is also a prior art.

[0075] Further, in step S1, starting the electric heating component 200 to electrically heat the food from the outside to the inside specifically includes:

[0076] S11, obtaining the shape of the food. Here, the maximum length, maximum width and maximum height of the food may be obtained.

[0077] S12, determining to turn on at least one of the top heating tube, the back heating tube and the bottom heating tube according to the shape of the food.

[0078] For example, if the food is a thin sheet structure, the top heating tube and the bottom heating tube are controlled to be turned on. For example, if the food is smaller than H1, the top heating tube and the bottom heating tube are controlled to be turned on, and H1 here can be set to 5 cm. If the food is similar to a triangular prism, such as the shape of a sandwich, the back heating tube and the bottom heating tube are controlled to be turned on.

[0079] In some embodiments, in step S3, the electric heating component 200 is turned off while the microwave heating component 300 is started to perform microwave heating on the food from the inside out. In some other embodiments, according to the needs, in step S3, the electric heating component 200 is not turned off while the microwave heating component 300 is started to perform microwave heating on the food from the inside out, and the electric heating component 200 is turned off at a certain time after the microwave heating component 300 is started.

[0080] Further, continue to refer to Figure 3 As shown, after step S3, the following steps are also included:

[0081] S31, after starting the microwave heating component 300 for a second preset time, using a microwave leakage meter to detect the amount of microwaves emitted by the microwave heating component 300;

[0082] If the microwave amount detected by the microwave leakage instrument is less than the microwave amount emitted by the microwave heating assembly 300, the alarm system of the microwave oven is activated to alarm and the microwave oven is controlled to shut down;

[0083] If the amount of microwaves detected by the microwave leakage instrument is equal to the amount of microwaves emitted by the microwave heating assembly 300, the microwave heating assembly 300 continues to work.

[0084] In some embodiments, the second preset time is set to 30 seconds according to demand. Specifically, if the detection mechanism detects that the maturity of the food is less than 90%, the frequency converter in the microwave heating component 300 is triggered, and the frequency converter transmits the signal to the magnetron, and the magnetron starts to work for 30 seconds, and the microwave leakage meter in the waveguide starts to work to detect whether there is microwave leakage. If it is determined that microwave leakage occurs, the display panel of the microwave oven directly alarms and controls the microwave oven to stop. After the maintenance personnel have modified the microwave heating component 300, it will be restarted; if the microwave leakage meter detects that there is no microwave leakage, then the waveguide works normally.

[0085] In some embodiments, after determining that the microwave heating assembly 300 can continue to work, the following steps are also included:

[0086] S32, every third preset time interval, use the detection mechanism to detect the maturity of the food, and determine whether the maturity of the food reaches a second target value, the second target value is not less than the first target value and not greater than 100%. If the maturity of the food reaches the second target value, proceed to S4; if the maturity of the food does not reach the second target value, the microwave heating component 300 continues to perform microwave heating on the food.

[0087] In some embodiments, the second target value may still be 90% or 95%. The third preset time length may be set to 1 minute or other time lengths according to requirements.

[0088] Furthermore, the number of times the detection mechanism detects the maturity of food every third preset time period is set to n. If the maturity of the food is still less than the second target value after the last detection, the heating power of the microwave heating component 300 is increased and S32 is repeated.

[0089] In some embodiments, the number n can be set to 3 or 5. The heating power of the microwave heating assembly 300 can be increased at an increase rate of 10%.

[0090] Further, in step S4, while the fan assembly is started to blow hot air to the food surface, the countdown mechanism of the microwave oven is started, and the fourth preset time is set, and after the fourth preset time is over, the fan assembly is turned off. In some embodiments, the time set by the countdown mechanism can be 10 minutes, and of course, the time set by the countdown mechanism can also be increased or decreased according to needs.

[0091] Further, in step S4, the microwave heating assembly 300 is turned off while the blower assembly is started to blow hot air to the food surface. Of course, the microwave heating assembly 300 can also be stopped at any time before the countdown ends.

[0092] In this embodiment, the microwave oven also includes a control mechanism, which can be a centralized or distributed controller. For example, the controller can be a single single-chip microcomputer, or it can be composed of multiple distributed single-chip microcomputers. The control program can be run in the single-chip microcomputer to control the electric heating component 200, the microwave heating component 300, the fan component, the detection mechanism, the countdown mechanism, the retractable mechanism, the movable mechanism, the alarm system and other components to realize their functions respectively.

[0093] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
