Cooking utensil can set up different culinary art time according to the difference of the edible material of cooking when cooking to make the culinary art time of edible material more accurate. The thickness of the food material affects the required cooking time, in addition to the variety of food material which affects the required cooking time. The thicker the food material, the more difficult it is to cook and therefore the longer the cooking time required, and the thinner the food material, the more easy it is to cook and therefore the shorter the cooking time required.

The existing cooking appliance generally judges the ripeness of the food material by detecting the temperature of the food material through a detection device, but the existing detection device generally can only detect the temperature, but neglects the influence of the thickness of the food material on the cooking time, so that the cooking time of the food material is still not accurate enough.

In view of this, the main objective of the present invention is to provide a detection device and a cooking utensil, which aims to solve the problem that the traditional detection device cannot detect the thickness of food material. Fig. 1 to 2 illustrate an embodiment of a cooking appliance according to the present invention, and fig. 3 to 6 illustrate an embodiment of a detection device according to the present invention.

Referring to fig. 3 to 5, the present invention provides a detection device 100 for detecting the temperature and thickness of a cooked food material 300 in a cooking apparatus 200, the detection device 100 comprising: the installation main part 1, the temperature measurement module 2 and the thickness measurement module 3. The mounting body 1 has opposite first and second ends 11, 12; the temperature measuring module 2 and the thickness measuring module 3 are arranged on the mounting main body 1, wherein the thickness measuring module 3 is provided with a thickness measuring part arranged at the first end 11 of the mounting main body 1, and the thickness measuring part is used for detecting the thickness of the food material 300.

The technical scheme of the utility model, thickness measuring module 3 is through locating the thickness measuring portion of the 1 first end 11 of installation main part detects eat material 300's thickness, thereby make cooking utensil 200 can be based on the thickness information that the thickness measuring portion recorded sets up the culinary art time. In addition, the detection device 100 is further provided with the temperature measurement module 2, the temperature measurement module 2 is used for detecting the temperature of the food material 300 during cooking, and the cooking appliance 200 stops heating the food material 300 when the temperature measurement module 2 detects that the temperature of the food material 300 reaches a preset temperature.

That is, the detection device 100 simultaneously detects the temperature and the thickness of the food material 300, so as to provide a basis for the cooking appliance 200 to set the cooking time, and the cooking time of the cooking appliance 200 is more accurate.

Further, the thermometric module 2 includes a thermometric probe 21 extending from the second end 12 of the mounting body 1.

The temperature measuring module 2 can detect the temperature of the food material 300 during cooking, so as to remind the cooking appliance 200 that the temperature of the food material 300 reaches a preset temperature, and the cooking time of the cooking appliance 200 is more accurate. Specifically, in this embodiment, the temperature measuring module 2 detects the temperature of the food material 300 through the temperature measuring probe 21, and the temperature measuring probe 21 is close to the food material 300, so as to detect the temperature of the food material 300 in real time during cooking.

In addition, the temperature probe 21 is disposed at the second end 12 of the mounting body 1 opposite to the thickness measuring module 3, so that the temperature probe 21 as a rod-shaped structure does not generate any interference to the thickness measuring module 3. In specific use, the detection device 100 detects the thickness of the food material 300 through the thickness measuring device before cooking, and sets the cooking time of the cooking appliance 200 according to the thickness of the food material 300; during cooking, the detection device 100 detects the temperature of the food material 300 in real time through the temperature probe 21, so that the cooking appliance 200 or the user can determine the cooking time according to the temperature of the food material 300. That is, the temperature measuring probe 21 is used at a different time from the thickness measuring portion and is mounted to a different end portion of the mounting body 1, so that they do not interfere with each other. Of course, when the temperature probe 21 and the thickness measuring portion do not interfere with each other, the temperature probe 21 and the thickness measuring portion may be installed at the same end.

Specifically, referring to fig. 4 to 5, a conventional temperature measuring element is often attached to the surface of the food material 300, and the temperature measuring element cannot sense the temperature inside the food material 300, so that the temperature measurement is not accurate, which may cause the cooking appliance 200 to misjudge the cooking time. Therefore, in this embodiment, one end of the temperature probe 21 away from the mounting body 1 is provided with the temperature sensor 22, and one end of the temperature probe 21 away from the mounting body 1 is tapered to form a piercing part 211, and the piercing part 211 is used for piercing the food material 300 so as to extend the temperature sensor 22 into the food material 300.

In this embodiment, the temperature probe 21 senses the temperature of the food material 300 through the temperature sensor 22, but the temperature probe 21 can penetrate into the interior of the food material 300 through the piercing part 211, so that the temperature sensor 22 disposed near the piercing part 211 can be inserted into the food material 300, and the temperature inside the food material 300 can be accurately measured.

The piercing part 211 is formed by the temperature probe 21 being tapered at the end far from the mounting body 1, and the end far from the mounting body 1 of the temperature probe 21 is also the end of the temperature probe 21 first contacting the food material 300, so that the food material 300 can be pierced smoothly.

Further, referring to fig. 5 and 6, the thickness measuring portion includes a sensing device, the first end 11 of the mounting body 1 is used for being attached to the food material 300 placed on the carrier 220, so that the sensing device is acted by the carrier 220 to generate a sensing signal, and the thickness of the food material 300 is obtained through the sensing signal.

In this embodiment, the first end 11 of the mounting body 1 is used for being attached to the food material 300 placed on the carrier 220, so the distance between the mounting body 1 and the carrier 220 is the thickness of the food material 300. When the sensing device is attached to the food material 300, the sensing device interacts with the carrier 220 to generate a sensing signal, and the intensity of an induced current determined by the distance between the mounting body 1 and the carrier 220, that is, the intensity of the sensing signal, so that the thickness of the food material 300 can be obtained according to the intensity of the sensing signal.

The carrier 220 is a component for carrying the food 300, and the carrier 220 and the induction device can induce a variety of ways, wherein the most common way is electromagnetic induction. In addition, the sensing manner between the carrier 220 and the sensing device may be to generate a sensing signal through laser ranging, and even the thickness measurement portion may directly measure the distance between the mounting body 1 and the carrier 220 through a measuring tool, and generate a corresponding sensing signal according to the measurement result, which is not limited herein.

In particular, the induction means comprise an induction coil 31.

In this embodiment, the induction device and the carrier 220 mutually induce through the induction coil 31, and the carrier 220 is made of a magnetic conductive material, so that the induction coil 31 and the carrier 220 can perform electromagnetic induction when being powered on. The carrier 220 may also be inductive with the induction coil 31 by an external inductor. Compared with other induction modes, the induction coil 31 occupies a smaller space and is more convenient to install on the installation main body 1.

In this embodiment, the first end 11 of the mounting body 1 is attached to the food material 300, which means that the first end 11 of the mounting body 1 is closest to the food material 300 and the carrier 220. Therefore, the mounting groove 13 for mounting the induction coil 31 is formed on the first end 11 of the mounting body 1, so that the induction coil 31 is closer to the carrier 220 and the food, and the sensing effect of the induction coil 31 is more accurate.

In addition, the cover plate 14 is disposed at the notch of the mounting groove 13, so as to isolate the induction coil 31 from the outside, thereby preventing the induction coil 31 from being polluted and damaged. In addition, when the induction coil 31 is aged, the cover plate 14 is directly opened, so that the induction coil 31 can be maintained and replaced, and the operation is very convenient.

Further, referring to fig. 4 to 6, in an embodiment of the present invention, the detecting device 100 further includes: and the wireless communication module is electrically connected with the temperature measuring module 2 and the thickness measuring module 3 respectively and is used for connecting the temperature measuring module 2 and the thickness measuring module 3 with the control device of the cooking utensil 200 in a communication way.

The control device may control the cooking time of the cooking appliance 200 according to the obtained temperature information and the thickness information, so that the cooking of the cooking appliance 200 is more accurate.

In another embodiment of the present invention, the detecting device 100 further includes a display module 4, the display module 4 is electrically connected to the temperature measuring module 2 and the thickness measuring module 3 respectively, for displaying the temperature and the thickness information of the food material 300.

Of course, can set up simultaneously among the detection device 100 display module 4 with wireless communication module, so make the temperature information that temperature measurement module 2 surveyed and the thickness information that thickness measurement module 3 surveyed more than can the direct transmission extremely cooking utensil 200's controlling means can also carry out the visual display to be convenient for master culinary art time more.

Referring to fig. 1 to 2, the present invention further provides a cooking apparatus 200, including: cooking body 210, carrier 220, heating device and detection device 100. A cooking cavity 211 is arranged in the cooking body 210, and an inlet and outlet 212 is arranged on one longitudinal side of the side wall of the cooking cavity 211; the carrier 220 is disposed in the cooking cavity 211 for carrying the food material 300; the heating device is arranged in the cooking cavity 211 and is used for heating the food material 300 on the carrier 220; the detection device 100 is the detection device 100 according to any one of the above embodiments.

In this embodiment, the cooking appliance 200 receives the food material 300 through the cooking cavity 211 in the cooking main body 210, and when in use, the food material 300 is placed in the carrier 220 and enters the cooking cavity 211 through the inlet/outlet 212. Thereafter, the heating device starts to heat the food material 300, and the temperature and thickness of the food material 300 are detected by the detecting device 100. The cooking appliance 200 controls the cooking time of the heating device according to the temperature and the thickness measured by the detection device 100, so as to prevent the food material 300 from being too long or too short, and ensure the cooking effect.

The cooking apparatus 200 may be provided in a variety of forms including, but not limited to, a rice cooker, a microwave oven, an induction cooker, an oven, and a steak machine. Among them, the rice cooker, the microwave oven, the oven and the steak maker have very strict requirements on cooking time, if the cooking time is too short, the food 300 may not be cooked, and if the cooking time is too long, the food 300 may be overcooked or even burnt, and thus it is very suitable for installing the detection apparatus 100.

Further, the carrier 220 is movably disposed in the cooking cavity 211 along the longitudinal direction, and has a working position stored in the cooking cavity 211 and an extending position extending out of the cooking cavity 211 during the movement; a cover 221 is disposed at one end of the carrier 220 close to the inlet/outlet 212, the cover 221 is configured to cover the inlet/outlet 212 when the carrier 220 is at the working position, and to open the inlet/outlet 212 when the carrier 220 is at the extending position.

In particular use, the food material 300 needs to be placed on the carrier 220, whereas in some cooking appliances 200 it is not convenient to place the food material 300 directly on the carrier 220. Therefore, the carrier 220 is movably arranged in the cooking cavity 211 along the longitudinal direction, so that the carrier 220 can be pulled out of the cooking cavity 211 when the food material 300 is placed, and the food material 300 can be conveniently placed and placed in the carrier 220. After the food material 300 is completely placed, the carrier 220 moves to the working position toward the cooking cavity 211, so that the cover 221 covers the access 212, thereby isolating the cooking cavity 211 from the outside.

The specific structure of the cover 221 corresponds to the access 212, so that when the cover 221 is located at the working position, the access 212 is covered. The cover 221 may be provided with a push-pull handle, so that when the device is used, a user may directly push and pull the push-pull handle, thereby pushing the carrier 220, and switching the position of the carrier 220, which is more convenient to operate.

Further, the thickness measuring portion includes a sensing device, the first end 11 of the mounting body 1 is used for attaching the food material 300 placed on the carrier 220; the carrier 220 is made of metal material, so that the sensing device generates a sensing signal.

One embodiment of the thickness measurement portion requires interaction with the carrier 220 to generate a sensing signal in a number of ways. In the present embodiment, the carrier 220 is made of metal, so as to generate electromagnetic induction with the induced current in the thickness measuring portion.

When the detecting device 100 is used, the first end 11 of the mounting body 1 will be attached to the food material 300 placed on the carrier 220. At this time, an induced current is generated in the thickness measurement portion, the induced current induces the carrier 220 to generate an induced signal, and the strength of the induced signal determined by the distance between the mounting body 1 and the carrier 220 is actually the thickness of the food material 300 between the mounting body 1 and the carrier 220, that is, the distance between the mounting body 1 and the carrier 220, so that the thickness of the food material 300 can be obtained according to the strength of the induced signal.

Further, in an embodiment of the temperature measuring module 2, the temperature measuring probe 21 is disposed, and the temperature measuring probe 21 can extend into the food material 300, so as to accurately measure the temperature inside the food material 300. During actual cooking, the temperature probe 21 needs to pierce into the food material 300, so that in the process, the temperature probe 21 is difficult to keep balance in the cooking cavity 211, and the temperature probe 21 may be separated from the food material 300, so that real-time temperature detection is problematic. Therefore, in an embodiment of the present invention, the carrier 220 has a jack; the temperature measuring module 2 comprises a temperature measuring probe 21 extending out of the mounting main body 1, and the temperature measuring probe 21 is used for penetrating through the food material 300 and being inserted into the jack.

In this embodiment, the temperature probe 21 is also close to the carrier 220 when inserted into the food material 300, so that the carrier 220 is provided with the insertion hole, and the temperature probe 21 can be inserted into the insertion hole when being close to the carrier 220, so as to limit the movement of the temperature probe 21 to a certain extent, thereby preventing the temperature probe 21 from being separated from the food material 300 and ensuring the stability of temperature measurement. Of course, when the food material 300 is placed on the carrier 220, the position of the insertion hole needs to be noticed, so as to prevent the temperature probe 21 from being inserted into the insertion hole.

Further, in specific use, the cooking time of the cooking appliance 200 determines the ripeness degree of the food material 300, and the ripeness degree of the food material 300 may cause different tastes, so that different cooking times need to be set according to the selection of the user and the food material 300 needs to be cooked to the degree of ripeness required by the user. However, after cooking is completed, the preheating in the cooking cavity 211 may continue to heat the food 300, which may cause the food 300 to be over-cooked, which may deviate from the actual needs and affect the user experience.

Therefore, in an embodiment of the present invention, the cooking apparatus 200 further includes: a drive device and a controller 230. The driving device is in driving connection with the carrier 220, and is used for driving the carrier 220 to move out of the cooking cavity 211; the controller 230 is electrically connected to the driving device, the heating device and the detecting device 100, and the controller 230 is configured to control the driving device and the heating device to operate according to the temperature and the thickness measured by the detecting device 100.

In this embodiment, the cooking appliance 200 is provided with the driving device, and the driving device can drive the carrier 220 to move out of the cooking cavity 211 in time after cooking is completed, so as to avoid over-cooking. Besides, the control device controls the heating device to work through the temperature and the thickness measured by the detection device 100. There are many ways in which the control device controls the heating device and the drive device. For example, when the temperature detected by the detecting device 100 reaches a preset temperature, the control device may control the heating device to stop heating, and control the driving device to drive the carrier 220 out of the cooking cavity 211. Or the controller 230 sets a preset time according to the thickness measured by the detection device 100, and when the heating time of the heating device reaches the preset time, the controller 230 controls the heating device to stop heating, and controls the driving device to drive the carrier 220 out of the cooking cavity 211.

The above only is the preferred embodiment of the present invention, not so limiting the patent scope of the present invention, all under the conception of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings is utilized, or the direct/indirect application is included in other related technical fields in the patent protection scope of the present invention.
