Description

Technical Field

[0001] The utility model relates to the technical field of cooking utensils, in particular to an oven. Background Art

[0002] In existing ovens, a temperature probe for detecting the cooking temperature is usually provided near the heating tube at the top of the inner pot.

[0003] However, since the temperature probe is far away from the baking tray and the food on the baking tray, there is a large difference between the temperature detected by the temperature probe and the actual cooking temperature, and the detection result is inaccurate, which may affect the cooking effect of the oven. Utility Model Content

[0004] Based on this, it is necessary to provide an oven to address the above problems, which can improve the accuracy of the detection results of the cooking temperature.

[0005] The utility model provides an oven, comprising: an inner pot, provided with a through hole; a temperature measuring component, arranged on the outer wall of the inner pot and comprising a temperature measuring piece that can slide relative to the inner pot, the temperature measuring piece comprising a temperature measuring end that can slide into the inner pot through the through hole; and an infrared sensor, arranged at the temperature measuring end and used for detecting the distance between the temperature measuring end and food or a baking tray.

[0006] In the above-mentioned oven, when it is necessary to detect the cooking temperature, the temperature measuring part is controlled to slide relative to the inner pot, so that the temperature measuring end extends into the inner pot through the through hole and gradually approaches the baking tray and the food placed on the baking tray, thereby reducing the difference between the temperature detected by the temperature measuring end and the actual cooking temperature and improving the accuracy of the detection result; at the same time, the infrared sensor detects the distance between the temperature measuring end and the food or baking tray in real time, so that the user can judge the position of the temperature measuring end and control the length of the temperature measuring end, while ensuring that the temperature measuring end can be close to the food and the baking tray, avoiding the temperature measuring end from touching the food or the baking tray.

[0007] In one of the embodiments, the temperature measuring component further includes a driving member disposed on the outer wall of the inner container and used to drive the temperature measuring member to slide relative to the inner container.

[0008] Such an arrangement can facilitate the user to adjust the position of the temperature measuring component and can ensure the position accuracy of the temperature measuring component.

[0009] In one of the embodiments, the driving member is configured to start or stop in response to the distance between the temperature measuring end and the food or the baking tray detected by the infrared sensor.

[0010] With such an arrangement, the start and stop of the driving component can be automatically controlled through a set program, which is convenient for user operation and improves the position accuracy of the temperature measuring component.

[0011] In one of the embodiments, the temperature measuring component further comprises a connecting member connected to an end of the temperature measuring member away from the temperature measuring end, and a size of the connecting member is larger than a size of the through hole.

[0012] With such arrangement, the connecting piece can limit the range of movement of the temperature measuring piece and can also prevent the temperature measuring piece from falling completely into the inner tank through the through hole, thereby improving the safety of the use of the temperature measuring piece.

[0013] In one embodiment, the driving member includes a driving part and an output part capable of relative movement, the driving part is arranged on the outer wall of the inner pot, the output part is connected to the connecting member, and can drive the temperature measuring member and the connecting member to slide relative to the inner pot.

[0014] With such arrangement, the connecting member can easily connect the output part with the temperature measuring member, so that the temperature measuring member and the driving member can be arranged side by side, avoiding increasing the size of the temperature measuring assembly along the sliding direction of the temperature measuring member.

[0015] In one embodiment, the output part is configured as a screw rod, the driving part is configured as a motor capable of driving the screw rod to rotate around its own axis, and the connecting member is provided with a threaded hole that is threadably matched with the screw rod.

[0016] Such an arrangement has a simple structure and low cost, and can also ensure the movement accuracy of the connecting member and the temperature measuring member.

[0017] In one embodiment, there are two driving members, and the two driving members are respectively arranged on both sides of the temperature measuring member.

[0018] Such an arrangement can prevent the temperature measuring component and the connecting component from tilting or deviating during movement, thereby improving the balance and stability of the temperature measuring component and the connecting component during sliding.

[0019] In one embodiment, the length L of the temperature measuring element extending into the inner container satisfies 0 to 15 cm.

[0020] Such a configuration ensures that the temperature measuring end will not completely withdraw from the through hole, thereby preventing oil stains in the inner pot from entering the space between the inner pot and the oven shell through the through hole; and can prevent the temperature measuring component from being too long, causing the temperature measuring component to protrude excessively from the outer wall of the inner pot when it is not extended into the inner pot.

[0021] In one embodiment, the temperature measuring component is arranged on the top wall of the inner container.

[0022] Such an arrangement can reasonably utilize the existing space in the oven without increasing the overall volume of the oven.

[0023] In one of the embodiments, the direction in which the temperature measuring component slides relative to the inner container is perpendicular to the top wall of the inner container.

[0024] This arrangement makes the movement path of the temperature measuring element the shortest and the easiest to control. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In existing ovens, a temperature probe for detecting the cooking temperature is usually provided near the heating tube at the top of the inner pot. However, since the temperature probe is far away from the baking tray and the food on the baking tray, the temperature detected by the temperature probe is greatly different from the actual cooking temperature, and the detection result is inaccurate, which may affect the cooking effect of the oven.

[0036] In order to solve the above problems, Figures 1 to 3 As shown, the utility model provides an oven, which can improve the accuracy of the detection result of the cooking temperature.

[0037] like Figures 1 to 3 As shown, specifically, the oven includes an inner pot 1, a temperature measuring component 2 and an infrared sensor, wherein: the inner pot 1 is provided with a through hole 11; the temperature measuring component 2 is arranged on the outer wall of the inner pot 1, and includes a temperature measuring component 21 that can slide relative to the inner pot 1, and the temperature measuring component 21 includes a temperature measuring end 211 that can slide into the inner pot 1 through the through hole 11; the infrared sensor is arranged at the temperature measuring end 211, and is used to detect the distance H between the temperature measuring end 211 and the food or the baking tray 3.

[0038] It can be understood that the two side walls of the inner pot 1 are usually provided with a plurality of brackets 12 for mounting the baking tray 3, and the plurality of brackets 12 are arranged at intervals along the height direction of the inner pot 1, and the user can mount the baking tray 3 on the brackets 12 of a suitable height as required. Moreover, different baking trays 3 have different depths, and different ingredients placed in the baking tray 3 have different heights.

[0039] In the oven provided by the utility model, when it is necessary to detect the cooking temperature, the temperature measuring element 21 is controlled to slide relative to the inner pot 1, so that the temperature measuring end 211 extends into the inner pot 1 through the through hole 11, and gradually approaches the baking tray 3 and the food placed on the baking tray 3, thereby reducing the difference between the temperature detected by the temperature measuring end 211 and the actual cooking temperature, and improving the accuracy of the detection result; at the same time, the infrared sensor detects the distance H between the temperature measuring end 211 and the food or the baking tray 3 in real time, so that the user can judge the position of the temperature measuring end 211, and controls the extension length of the temperature measuring end 211, while ensuring that the temperature measuring end 211 can be close to the food and the baking tray 3, avoiding the temperature measuring end 211 from touching the food or the baking tray 3; thereby, the oven can be more accurate when adjusting the cooking program according to the detection result of the temperature measuring end 211, so as to improve the cooking effect of the oven.

[0040] The oven can adjust parameters such as heating time, power, humidity, etc. according to the detection result of the temperature measuring end 211 to adjust the cooking program.

[0041] like Figure 2 As shown, the temperature measuring component 2 also includes a driving member 22 disposed on the outer wall of the inner pot 1 and used to drive the temperature measuring member 21 to slide relative to the inner pot 1. The user can manually or programmatically control the start and stop of the driving member 22 to drive the temperature measuring member 21 to slide relative to the inner pot 1. During the cooking process, when the infrared sensor detects that the distance H between the temperature measuring end 211 and the food or the baking tray 3 is large, the driving member 22 is controlled to start and drive the temperature measuring member 21 to slide relative to the inner pot 1 close to the food and the baking tray 3; when the infrared sensor detects that the distance H between the temperature measuring end 211 and the food or the baking tray 3 meets the detection requirements, the driving member 22 is controlled to stop, so that the temperature measuring member 21 is stationary relative to the food and the baking tray 3; after cooking is completed, the driving member 22 is controlled to start and drive the temperature measuring member 21 to slide relative to the inner pot 1 away from the food and the baking tray 3. Thereby, it is convenient for the user to adjust the position of the temperature measuring member 21, and the position accuracy of the temperature measuring member 21 can be guaranteed, avoiding the problems of cumbersome operation or low position accuracy of the temperature measuring member 21 caused by manually controlling the sliding of the temperature measuring member 21.

[0042] like Figure 3As shown, the driving member 22 is configured to start or stop in response to the distance H between the temperature measuring end 211 and the food or baking tray 3 detected by the infrared sensor. For example, during the cooking process, when the infrared sensor detects that the distance H between the temperature measuring end 211 and the food or baking tray 3 is greater than 5 cm, the driving member 22 starts and drives the temperature measuring member 21 to slide relative to the inner pot 1 and approach the food and baking tray 3; when the infrared sensor detects that the distance H between the temperature measuring end 211 and the food or baking tray 3 is equal to 5 cm, the driving member 22 stops. Thus, the start and stop of the driving member 22 can be automatically controlled by the program set in the oven, which further facilitates the user's operation and improves the position accuracy of the temperature measuring member 21.

[0043] Of course, according to actual needs, when the distance H is greater than other values ​​such as 3cm, 4cm, 6cm or 7cm, the driving member 22 starts and drives the temperature measuring member 21 to slide relative to the inner pot 1 close to the food and the baking tray 3; correspondingly, when the distance H is equal to other values ​​such as 3cm, 4cm, 6cm or 7cm, the driving member 22 stops. As long as the temperature measuring end 211 of the temperature measuring member 21 does not touch the food or the baking tray 3 during the temperature measurement process, the embodiments of the present utility model are not specifically limited here.

[0044] like Figure 3 As shown, the length L of the temperature measuring member 21 extending into the inner pot 1 satisfies 0 to 15 cm. Among them, the length L can be any value within the range of 0 to 15 cm, such as 0, 1 cm, 2 cm... 14 cm, 15 cm, etc. When the length L of the temperature measuring member 21 extending into the inner pot 1 is 0, the temperature measuring end 211 is flush with the inner top wall of the inner pot 1, thereby ensuring that the temperature measuring end 211 will not completely withdraw from the through hole 11, and preventing the oil stains in the inner pot 1 from entering the space between the inner pot 1 and the oven shell through the through hole 11. In addition, the length L satisfies 0 to 15 cm so that the temperature measuring member 21 can slide to a position where the distance H between the temperature measuring end 211 and the food or baking tray 3 is about 5 cm in most cases, so as to ensure the accuracy of the detection result of the temperature measuring end 211. At the same time, it can also avoid the temperature measuring member 21 being too long, which causes the temperature measuring member 21 to protrude excessively from the outer wall of the inner pot 1 when it is not extended into the inner pot 1, thereby causing the overall volume of the oven to be too large.

[0045] like Figure 2 As shown, the temperature measuring assembly 2 further includes a connecting piece 23 connected to one end of the temperature measuring element 21 away from the temperature measuring end 211, and the size of the connecting piece 23 is larger than the size of the through hole 11. When the connecting piece 23 abuts against the top wall of the inner pot 1, the temperature measuring element 21 cannot slide further relative to the inner pot 1 to approach the food and the baking tray 3, thereby limiting the range of movement of the temperature measuring element 21, and the connecting piece 23 can also prevent the temperature measuring element 21 from completely falling into the inner pot 1 through the through hole 11, thereby improving the safety of the use of the temperature measuring element 21.

[0046] like Figure 2 As shown, the driving member 22 includes a driving portion 221 and an output portion 222 capable of relative movement, the driving portion 221 being disposed on the outer wall of the inner pot 1, the output portion 222 being connected to the connecting member 23, and capable of driving the temperature measuring member 21 and the connecting member 23 to slide relative to the inner pot 1. The connecting member 23 can also facilitate the connection of the output portion 222 with the temperature measuring member 21, so that the temperature measuring member 21 and the driving member 22 can be arranged side by side, avoiding increasing the size of the temperature measuring assembly 2 along the sliding direction of the temperature measuring member 21, thereby avoiding increasing the size of the oven.

[0047] In the illustrated embodiment, the output part 222 is configured as a screw, the driving part 221 is configured as a motor capable of driving the screw to rotate around its own axis, and the connecting member 23 is provided with a threaded hole that is threadedly matched with the screw. The structure of the screw and the threaded hole is simple, which is convenient for the production and processing of the temperature measuring component 2, has a low cost, and can also ensure the movement accuracy of the connecting member 23 and the temperature measuring member 21, thereby ensuring the accuracy of the detection result of the temperature measuring member 21.

[0048] Of course, in other embodiments, the driving part 221 can also be set as an electric guide rail, and the output part 222 can be set as a slider slidably set on the electric guide rail; or, the driving part 221 can also be set as a cylinder, and the output part 222 can be set as a piston slidably set in the cylinder. As long as the connecting part 23 and the temperature measuring part 21 can be driven to slide back and forth in a straight line together so that the temperature measuring end 211 can slide close to or away from the food and the baking tray 3, the embodiments of the utility model are not specifically limited here.

[0049] like Figure 2 As shown, the number of driving members 22 is two, and the two driving members 22 are respectively arranged on both sides of the temperature measuring member 21. The two driving members 22 synchronously drive the connecting member 23 and the temperature measuring member 21 to slide relative to the inner tank 1, and the two driving members 22 are respectively arranged on both sides of the temperature measuring member 21, so as to avoid the temperature measuring member 21 and the connecting member 23 from tilting or shifting during the movement, resulting in the phenomenon of getting stuck between the temperature measuring member 21 and the through hole 11, so as to improve the balance and stability of the temperature measuring member 21 and the connecting member 23 during the sliding process. Among them, the connecting line between the two driving members 22 and the temperature measuring member 21 can be a straight line or a triangle. Of course, the number of driving members 22 can also be one, three or more, as long as it can stably drive the temperature measuring member 21 to slide back and forth in a straight line relative to the inner tank 1, and the embodiment of the utility model is not specifically limited here.

[0050] like Figure 1 and Figure 3As shown, in the illustrated embodiment, the temperature measuring component 2 is arranged on the top wall of the inner pot 1. Since other components need to be installed on the top of the upper inner pot 1, there is usually a large space between the top wall of the inner pot 1 and the oven shell. Arranging the temperature measuring component 2 on the top wall of the inner pot 1 can reasonably utilize the existing space in the oven without increasing the overall volume of the oven.

[0051] And, if Figure 3 As shown in the rectangular coordinate system, the direction in which the temperature measuring element 21 slides relative to the inner pot 1 is perpendicular to the top wall of the inner pot 1. The top wall of the inner pot 1 is arranged perpendicular to the ±Y axis, and the temperature measuring element 21 can slide relative to the inner pot 1 along the -Y axis direction to approach the food and the baking tray 3, and can slide along the +Y axis direction away from the food and the baking tray 3. This makes the movement path of the temperature measuring element 21 the shortest and the easiest to control.

[0052] In other embodiments, the temperature measuring component 2 may also be disposed on the bottom wall of the inner pot 1, in which case the temperature measuring component 21 can slide relative to the inner pot 1 along the +Y axis direction to approach the food and the baking tray 3, and can slide relative to the inner pot 1 along the -Y axis direction to move away from the food and the baking tray 3. Alternatively, the temperature measuring component 2 may also be disposed on the side wall of the inner pot 1, and the temperature measuring component 21 can slide relative to the inner pot 1 along the ±X axis direction to move closer to or away from the food and the baking tray 3. Of course, the sliding direction of the temperature measuring component 21 may also be arranged at an acute angle or an obtuse angle with the top wall, bottom wall or side wall of the inner pot 1, as long as it is ensured that the temperature measuring component 21 does not interfere with other structures inside the oven during the sliding process, and the embodiments of the utility model are not specifically limited here.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
