Description

Self-adjusting oven

Technical Field

The invention relates to the technical field of kitchen equipment, in particular to a self-adjusting oven.

Background

The bread oven is an electrical device specially used for baking bread, and the bread oven can adjust the baking temperature to adapt to the baking requirements of different types of bread. Generally, the temperature of the baked bread is between 150 ℃ and 220 ℃. The baking time can be set for the bread baking oven, so that the baking degree of the bread is ensured to be proper. The baking time varies depending on the size, shape and kind of bread. Common heating modes of the bread oven are upper and lower heating pipes for heating, hot air circulation heating and the like. The upper and lower heating pipes can uniformly heat the surface of the bread, and the hot air circulation heating can improve the baking efficiency, so that the bread is crisp. Bread ovens are typically equipped with a baking tray and a baking net to hold bread for baking. The baking tray can be used for baking whole bread or sliced bread, and the baking net is suitable for baking small bread or bread.

Prior to baking, the dough needs to be fermented to expand its volume. During fermentation, yeast breaks down sugar in the dough, producing carbon dioxide gas, which expands the dough and thus the bread becomes fluffy. During the baking process, the temperature in the bread oven will gradually rise, and the moisture in the dough will gradually evaporate, forming bubbles. These bubbles will expand the dough, thus making the bread fluffy. However, the existing bread baking oven generally uses a preset program to bake specific types of bread to achieve the corresponding degree of bulk, and if some processing parameters change during the baking process, such as abnormal temperature rising curve of the baking oven, the quality parameters such as the degree of bulk of the bread cannot reach the ideal level.

The embodiment of the invention provides a self-adjusting oven which is suitable for baking various foods, in particular for baking videos such as bread and the like with certain fluffiness requirement. Specifically, as shown in fig. 1 to 3, the self-adjusting oven provided in the embodiment of the present invention includes:

The main housing 100, the main housing 100 serves as a main body frame of the self-adjusting toaster, on one hand, for forming an internal environment relatively isolated from an external environment to complete food processing operations within the internal environment, and on the other hand, the main housing 100 serves as a mounting base for other components and forms a relatively integral body after the other components are mounted. The main casing 100 is internally provided with a first liner 110, a first heating chamber is formed inside the first liner 110, and the first liner 110 generally has good heat insulation performance, so that heat exchange between the first heating chamber and the external environment is less, and the temperature in the first heating chamber is controllable. The first heating chamber is internally provided with a baking area for accommodating the baked object, the baking area can be a partial area of the first heating chamber, the two areas are not obviously distinguished in physical space and property, only the areas are divided, and the baking area can also be a relatively independent part in the first heating chamber and is isolated by a physical isolation or other modes, so that the baking area and other areas in the first heating chamber have heat difference so as to facilitate baking.

The first heating cavity is internally provided with a first heating device, the first heating device is used for controlling the temperature in the first heating cavity, the first heating device can be heating elements such as a heating pipe, and the first heating device emits heat during working so as to heat food materials in the first heating cavity. Generally, the oven has a heating function during baking, and the first heating device mainly has a heating function, but under certain baking requirements, the first heating device also has a temperature equalizing and controlling function.

A probe 200 is disposed in the first heating chamber, the probe 200 being movable relative to the baking area and detecting the degree of bulk of the object to be baked while moving. For example, a pressure sensor is provided on the probe 200, and when the probe 200 moves and contacts the object to be baked, the pressure sensor detects a contact force between the probe 200 and the object to be baked, and determines the bulk of the object to be baked according to the magnitude of the contact force. The bulk is a defined index, and the value is the ratio between the size of the object to be baked when no external force is applied to the object to be baked in a certain direction and the size of the object to be baked when external force is applied to the object to be baked in the same direction until the object to be baked cannot be compressed, for example, the size of the chiffon bread in the length direction is 20cm when no external force is applied to one side of the chiffon bread in the length direction, so that the chiffon bread is forced to deform until the chiffon bread cannot be compressed, the size of the chiffon bread in the length direction is 4cm, and the fluffiness of the chiffon bread is 5. It should be noted that, when the probe 200 is used to press the object to be baked to measure the bulk, the object to be baked is not compressed to be incompressible, but the bulk of the bread is determined by the force when the probe 200 is abutted against the surface of the object to be baked, and the higher the bulk, the more easily the deformation occurs, so the force applied to the probe 200 is smaller.

The self-adjusting oven is further provided with a controller for controlling the first heating device to work according to user operation instructions, the controller can be integrated in a self-adjusting oven operation system, the user sends operation instructions, such as low-temperature baking, quick baking and the like, to the controller through an oven operation interface, and after the controller receives the operation instructions, the controller controls the heating temperature, the heating rate and the like of the first heating device according to the operation instruction types. In addition, the self-adjusting oven can adjust the parameters of the first heating device according to the detection result of the probe 200, for example, if the detection result of the probe 200 shows that the current bulk of the object to be baked is lower than the ideal bulk in the baking process, the controller can adjust the heating temperature and the temperature change rate of the first heating device after receiving the detection result, so that the bulk of the object to be baked reaches the ideal state. It should be noted that, in different baking stages, the influence of parameters such as temperature, temperature change rate and the like on the degree of bulk is inconsistent, for example, in the case of bread with higher water content, the higher temperature in the early stage of baking can enable the degree of bulk of the bread to be rapidly increased, and the higher temperature in the later stage of baking can enable the degree of bulk of the bread to be reduced, so that the controller can determine according to the type of the article to be baked and the baking stage based on the regulation of the degree of bulk on the first heating device.

Therefore, according to the self-adjusting oven provided by the embodiment of the invention, by arranging the movable probe 200, the probe 200 can be abutted against the object to be baked when moving and measure parameters such as the bulk degree of the object to be baked, and the controller adjusts the parameters such as the heating temperature of the first heating device according to the detection result of the probe 200, so that the object to be baked has good taste.

In one embodiment, the probe 200 includes an expansion 202 of the body portion 201, the expansion 202 being relatively close to the baking region and the body portion 201 being relatively far from the baking region when the probe 200 is moved relative to the baking region, the expansion 202 having a cross-sectional dimension that is greater than the cross-sectional dimension of the body portion 201. When the probe 200 abuts against the object to be baked, the expansion part 202 is larger in size, can be better contacted with the object to be baked, and detects the resistance of the object to be baked to the movement of the probe 200. The expansion part 202 may be located at the end of the probe 200, that is, the expansion part 202 is first contacted with the object to be baked, but the main body part 201 is not contacted with the object to be baked, or the expansion part 202 may be located near the end of the probe 200, the end of the probe 200 is a part of the main body part 201, when contacting with the object to be baked, the main body part 201 is first contacted with the object to be baked, and the main body part 201 pierces the surface of the object to be baked and pierces the inside of the object to be baked, and then the expansion part 202 is contacted with the surface of the object to be baked again, so that the pierced part of the main body part 201 cannot pierce the deeper depth.

In one embodiment, the interface size of the expansion portion 202 is 2-10 times that of the main body portion 201. Generally, the main body 201 is in an elongated cylindrical shape, the length is between 10cm and 30cm, the diameter is between 0.2 cm and 2cm, the whole of the expansion part 202 is slightly in a circular sheet shape, the diameter of the expansion part 202 is between 0.5cm and 5cm, and the thickness is between 0.2 cm and 1 cm. The dimensions of the expansion 202 may be adapted for different kinds of objects to be baked, for example, for objects to be baked with a larger bulk, the dimensions of the expansion 202 are correspondingly larger, and for objects to be baked with a smaller bulk, the dimensions of the expansion 202 are correspondingly smaller. For different types of objects to be baked, the dimensions of the main body 201 and the expansion part 202 in the probe 200 can be adjusted adaptively, for example, when the expansion part 202 is detachably mounted on the main body 201 and the expansion part 202 needs to be replaced, the original expansion part 202 is removed from the main body 201, and a new expansion part 202 is mounted on the main body 201.

In one embodiment, the probe 200 includes a needling portion 203, an expanding portion 202 and a main body portion 201, the needling portion 203 is located at an end of the probe 200, the expanding portion 202 is located near the end of the probe 200, the main body portion 201 is located far from the end of the probe 200, when contacting with an object to be baked, the needling portion 203 is firstly contacted with the object to be baked, because the needling portion 203 has a relatively small size, the needling portion 203 punctures the surface of the object to be baked, penetrates into the interior of the object to be baked, and then the expanding portion 202 is contacted with the surface of the object to be baked again, at this time, the puncturing portion of the needling portion 203 does not puncture to a deeper depth, and the main body portion 201 does not directly contact with the object to be baked.

In one embodiment, the end of the probe 200 near the baking area is provided with a temperature tester capable of measuring the temperature at the end of the probe 200. Generally, the oven has a temperature detecting function for detecting the temperature inside the oven, but the temperature detecting device in the existing oven is often arranged on the peripheral wall of the oven liner, and the temperature detecting position of the temperature detecting device is far away from the baking area and is generally close to the heating device, so that the temperature detected by the temperature detecting device is greatly different from the temperature at the baking area. A temperature tester is provided at the end of the probe 200, which can approach the baking area or directly contact the object to be baked, thereby measuring a more accurate temperature of the object to be baked. In particular, the end of the probe 200 is capable of piercing the surface of the object to be baked and penetrating into the interior of the object to be baked, thereby measuring the temperature inside the object to be baked.

In one embodiment, the probe 200 is internally provided with a hollow passage extending through the entire probe 200 and having an inlet end and an outlet end, the outlet end being located at the end of the probe 200 near the baking area, the inlet end being located at the end of the probe 200 remote from the baking area, the outlet end being located near or inside the object to be baked, the inlet end being in communication with a heat source inside the oven. Through the hollow channel, the gas with preset temperature can be conveyed to a specific area of the object to be baked, or the gas with preset temperature can be conveyed to the inside of the object to be baked, so that different baking requirements can be met. For example, in the case of bread baking, by supplying high-temperature gas to the inside of bread while baking the surface of the bread at high temperature, the surface and specific areas inside of the bread can be made crispy, and a special taste can be achieved.

In one embodiment, a moving assembly is disposed inside the oven and disposed in the first liner 110, and the moving assembly can drive the probe 200 to move relative to the baking area. Specifically, the moving assembly includes driving motor, actuating lever and actuating nut, driving motor shell fixed connection is in first inner bag 110, driving motor and actuating lever transmission are connected, the actuating motor can drive the actuating lever corotation or reversal, the nut screw pair is constituteed to actuating lever and actuating nut, the actuating lever rotation can drive the actuating nut along actuating lever axial slip, actuating nut and probe 200 fixed connection, the sliding of actuating nut drives probe 200 and slides, so that probe 200 moves for the area of toasting, can be when toasting from this, make probe 200 move for waiting to toast the object. It is understood that other common drive patterns capable of driving the probe 200 relative to the baking zone may be used with the present invention, such as linear drive motors. In addition, the relative movement between the probe 200 and the baking area can be achieved by driving the baking area to move, for example, for a toaster with a sliding tray, the object to be baked is placed on the sliding tray, the probe 200 is fixed on the inner wall of the toaster, and when the driving mechanism in the toaster drives the sliding tray to move, the object to be baked moves relative to the probe 200.

In one embodiment, the main housing 100 is further provided with a second inner container 120, and a second heating chamber is formed inside the second inner container 120, and the second inner container 120 has good heat insulation performance, so that heat exchange between the second heating chamber and other environments is less, and the temperature in the second heating chamber is controllable. Typically, the temperature in the second heating chamber is higher than the temperature in the first heating chamber. A connecting channel is arranged between the second heating chamber and the first heating chamber, the connecting channel can be controlled by the controller to be opened and closed, and when the connecting channel is opened, high-temperature gas in the second heating chamber enters the first heating chamber so as to enable the first heating chamber to be heated up rapidly. In particular, the connection channel may be disposed near the baking area, so that the high-temperature gas in the second heating chamber directly enters the baking area and heats the object to be baked, or the connection channel may be disposed in the probe 200, that is, one end of the probe 200 is communicated with the second heating chamber, and the other end can extend into the baking area or the interior of the object to be baked.
