Description

Technical Field

[0001] This utility model relates to the field of cooking utensil technology, and in particular to a temperature measuring device and cooking equipment. Background Technology

[0002] In cooking equipment, temperature measuring devices (such as infrared thermometers) are typically used to monitor the temperature of the food to assist the control system in precisely adjusting the temperature and humidity inside the inner pot, improving the cooking effect, and providing users with feedback on the cooking status.

[0003] However, during steaming, a large amount of water vapor is generated inside the inner pot. This water vapor easily condenses into water droplets or even dirt on the surface of the infrared temperature sensor, severely obstructing the detection light path and causing the temperature measurement function to fail. Even when switching to the baking or microwave function, the contaminated infrared temperature sensor still cannot accurately measure the temperature, affecting the control accuracy of the cooking process and the user experience. Therefore, existing infrared temperature sensors are generally not applicable to cooking appliances with steaming functions, limiting their scope of use. Utility Model Content

[0004] Therefore, it is necessary to provide a temperature measuring device and cooking equipment to address the above problems. The temperature measuring device can be used in cooking equipment with steaming function.

[0005] This utility model provides a temperature measuring device for installation in an inner liner, the inner liner having an opening on its wall. The device includes: a temperature measuring element, positioned outside the inner liner and facing the opening, capable of transmitting / receiving temperature signals through the opening; and a blocking assembly, positioned outside the inner liner, the blocking assembly including a blocking member movable relative to the inner liner, the blocking member having a closed state and an open state. In the closed state, the blocking member blocks the opening; in the open state, the blocking member separates from the opening and moves away from the transmission path of the temperature signal.

[0006] In the aforementioned temperature measuring device, during cooking modes with low moisture content inside the inner pot, such as baking or microwave functions, the shield can be moved to the open state, allowing the temperature measuring element to monitor the temperature of the inner pot and the food inside through the opening, without interfering with the normal transmission of the temperature signal. During cooking modes with high moisture content inside the inner pot, such as steam functions, the shield can be moved to the closed state, sealing the opening and preventing moisture from escaping and contacting the temperature measuring element. This prevents water droplets from condensing and scale from forming on the temperature measuring element, thus protecting it. This prevents moisture from affecting the temperature measuring element, ensuring the accuracy of the temperature measurement results. This allows the device to be used in cooking equipment with steaming functions, expanding its applicability in multi-mode cooking environments, extending its service life. Furthermore, the device has a simple structure, convenient and quick switching of the shield state, and low cost.

[0007] In one embodiment, the shield can slide relative to the inner liner in a preset direction toward / away from the opening to switch between the closed state and the open state.

[0008] With this configuration, the movement path of the shielding component is simple and easy to control. At the same time, it can ensure that the shielding component accurately covers the opening or moves away from the transmission path of the temperature signal, thereby improving the accuracy and reliability of the shielding component's action.

[0009] In one embodiment, the transmission path of the temperature signal is parallel to the axis of the opening, and the preset direction forms an angle with the axis of the opening.

[0010] This design allows the temperature signal to pass through the opening more effectively, preventing interference from the edges or inner walls of the opening. It also ensures that the shielding component does not interfere with the temperature measuring component during movement.

[0011] In one embodiment, the shielding component further includes a driving member, the output end of which is connected to the shielding member and is capable of extending / retracting toward the opening in the preset direction to drive the shielding member to slide closer to / away from the opening.

[0012] With this setup, the blocking component is driven to slide along a preset direction by the driving component, eliminating the need for manual adjustment. This makes the operation simple and convenient, and ensures that the blocking component's position is accurate.

[0013] In one embodiment, the temperature measuring device further includes a seal for being disposed at the edge of the opening, wherein in the closed state, the shielding member abuts against the seal.

[0014] This design allows the shielding component to compress the sealing component when blocking the opening, improving the sealing effect and preventing moisture and heat from leaking out of the inner liner. It also improves the stability of the shielding component when it is closed, reducing vibration and displacement.

[0015] In one embodiment, the temperature measuring device further includes a bracket for mounting on the outer wall of the inner liner, and the temperature measuring element and the shielding assembly are both mounted on the bracket.

[0016] With this configuration, the bracket is used to support and fix the temperature measuring element and the shielding component, so that the temperature measuring device can be fixed to the inner liner as a whole, simplifying the assembly process and ensuring the relative positional accuracy between the temperature measuring element, the shielding component and the opening.

[0017] In one embodiment, the temperature measuring element is an infrared temperature measuring element.

[0018] With this setup, the infrared temperature sensor can be used in high-temperature cooking environments, enabling non-contact and accurate measurement of food surface temperature, with fast response, high accuracy, and low cost.

[0019] This utility model also provides a cooking device, including: an inner pot, the wall of which has an opening; and the temperature measuring device.

[0020] In one embodiment, the inner liner further includes a flange extending outward from the edge of the opening, the flange having a height dimension of 3mm to 6mm.

[0021] This design allows the folded edge to act as a microwave shield, reducing microwave energy leakage from the opening during microwave cooking and improving safety.

[0022] In one embodiment, the inner liner includes a top wall, a rear wall, and an inclined section connecting the top wall and the rear wall, with the opening located in the inclined section.

[0023] This design allows the temperature sensor to be better aligned with the surface of the food in the middle or bottom of the inner pot, thereby obtaining a more accurate temperature signal and improving temperature measurement accuracy. Attached Figure Description

[0034] In cooking equipment, temperature sensors (such as infrared thermometers) are typically used to monitor food temperature, assisting the control system in precisely adjusting the temperature and humidity inside the cooking chamber to improve cooking results and provide users with feedback on the cooking status. However, during steaming, a large amount of water vapor is generated inside the chamber. This vapor easily condenses into water droplets or even dirt on the surface of the infrared thermometer, severely obstructing the detection light path and causing the temperature measurement function to fail. Even when switching to baking or microwave functions, the contaminated infrared thermometer cannot accurately measure the temperature, affecting the control accuracy of the cooking process and the user experience. Therefore, existing infrared thermometers are generally not applicable to cooking equipment with steaming functions, limiting their scope of use.

[0035] To solve the above problems, such as Figures 1 to 3 As shown, this utility model provides a temperature measuring device and a cooking equipment, which can be used in cooking equipment with steaming function.

[0036] like Figures 1 to 3 As shown, specifically, the temperature measuring device 100 is installed in the inner liner 200, and the inner liner 200 has an opening 201 on its wall. The temperature measuring device 100 includes a temperature measuring element 1 and a shielding assembly 2, wherein: the temperature measuring element 1 is installed outside the inner liner 200 and faces the opening 201, and the temperature measuring element 1 can transmit or receive temperature signals through the opening 201; the shielding assembly 2 is installed outside the inner liner 200, and the shielding assembly 2 includes a shielding member 21 that can move relative to the inner liner 200. The shielding member 21 has a closed state and an open state. In the closed state, the shielding member 21 blocks the opening 201. In the open state, the shielding member 21 is separated from the opening 201 and moves away from the temperature signal transmission path a.

[0037] In the temperature measuring device 100 provided in this embodiment of the present invention, during cooking states where there is little moisture inside the inner pot 200, such as baking or microwave functions, the shielding member 21 can be moved to the open state, allowing the temperature measuring element 1 to transmit or receive temperature signals through the opening 201 to monitor the temperature of the inner pot 200 and the food inside it. Furthermore, the shielding member 21 is located away from the temperature signal transmission path a, ensuring that it does not interfere with the normal transmission of the temperature signal. During cooking states where there is more moisture inside the inner pot 200, such as steaming functions, the shielding member 21 can be moved to the closed state, sealing the inner pot 200. The opening 201 is blocked to prevent water vapor inside the inner liner 200 from overflowing through the opening 201 and contacting the temperature measuring element 1, thereby preventing water droplets from condensing and scale from forming on the temperature measuring element 1, thus protecting the temperature measuring element 1. In this way, the water vapor inside the inner liner 200 can be prevented from affecting the temperature measuring element 1, ensuring the accuracy of the temperature measurement results. This allows the temperature measuring device 100 to be used in cooking equipment with steaming function, expanding the applicability of the temperature measuring device 100 in multi-mode cooking environments, extending its service life. Furthermore, the temperature measuring device 100 has a simple structure, the blocking element 21 can be switched in a convenient and quick manner, and the cost is low.

[0038] In one embodiment, the temperature measuring element 1 is an infrared temperature measuring element, such as an infrared camera or infrared sensor. Infrared temperature measuring elements are suitable for high-temperature cooking environments, enabling non-contact, accurate measurement of food surface temperature, and offer fast response, high accuracy, and low cost. Of course, in other embodiments, the temperature measuring element 1 can also be other non-contact temperature measuring elements such as fiber optic sensors; this embodiment of the present invention does not impose specific limitations.

[0039] like Figure 3 As shown, in one embodiment, the blocking member 21 can slide relative to the inner liner 200 along a preset direction c, approaching or moving away from the opening 201, to switch between a closed state and an open state. The movement path of the blocking member 21 is simple and easy to control, while ensuring that the blocking member 21 accurately covers the opening 201 or moves away from the position of the temperature signal transmission path a, thereby improving the accuracy and reliability of the blocking member 21's operation.

[0040] like Figure 3 As shown in the illustrated embodiment, the temperature signal transmission path a is parallel to the axis b of the opening 201, and the preset direction c forms an angle with the axis b of the opening 201. The parallelism of the temperature signal transmission path a to the axis b of the opening 201 allows the temperature signal to pass through the opening 201 more effectively, preventing interference from the edges or inner walls of the opening 201. The angle between the preset direction c and the axis b of the opening 201 ensures that the blocking member 21 will not interfere with the temperature measuring member 1 during movement. The angle between the preset direction c and the axis b of the opening 201 can be any angle, such as 30 degrees, 45 degrees, 60 degrees, or 90 degrees, as long as it ensures that the blocking member 21 can open or close the opening 201 normally without interfering with the temperature measuring member 1. This embodiment of the invention does not impose specific limitations here.

[0041] Of course, in other embodiments, the transmission path a of the temperature signal can also be at an angle to the axis b of the opening 201, as long as the temperature signal can be transmitted normally through the opening 201. In this case, the preset direction c can be at an angle to the axis b of the opening 201 or parallel to the axis b of the opening 201, as long as the blocking member 21 can open or close the opening 201 normally without interfering with the temperature measuring member 1. Alternatively, the blocking member 21 can also slide along other regular or irregular shaped movement paths such as arcs or waves to switch between the closed and open states; the blocking member 21 can also rotate relative to the inner liner 200. In the closed state, the blocking member 21 rotates to a position that completely covers the opening 201, and in the open state, the blocking member 21 rotates to a position that is completely misaligned with the opening 201.

[0042] like Figure 3As shown, in one embodiment, the shielding member 21 includes a shielding surface 211 parallel to the plane of the opening 201, to ensure that the shielding member 21 can completely cover the opening 201 in the closed state. Of course, in other embodiments, in the closed state, the shielding member 21 may also extend at least partially into the opening 201 to block the opening 201.

[0043] like Figure 3 As shown, in one embodiment, the blocking component 2 further includes a driving member 22. The output end 221 of the driving member 22 is connected to the blocking member 21 and can extend or retract along a preset direction c toward the opening 201 to drive the blocking member 21 to slide closer to or away from the opening 201. Thus, by driving the blocking member 21 to slide along the preset direction c via the driving member 22, no manual adjustment is required, making operation simple and convenient, and ensuring the accurate positioning of the blocking member 21. The driving member 22 can be a linear drive element such as an electric push rod, linear motor, electromagnetic solenoid, cylinder, or hydraulic cylinder, or it can be a drive structure formed by the cooperation of a motor and transmission elements such as a gear and rack, as long as it can drive the blocking member 21 to slide closer to or away from the opening 201 along the preset direction c. This embodiment of the present invention does not impose specific limitations. Of course, in other embodiments, the blocking component 2 may not include the driving member 22, and the blocking member 21 may be controlled to switch between a closed state and an open state by manual adjustment.

[0044] like Figures 2 to 3 As shown, the temperature measuring device 100 also includes a sealing element 3, which is disposed at the edge of the opening 201. In the closed state, the blocking element 21 abuts against the sealing element 3. When the blocking element 21 blocks the opening 201, it can compress the sealing element 3, improve the sealing effect, and further prevent water vapor and heat inside the inner liner 200 from escaping through the opening 201. At the same time, it can also improve the stability of the blocking element 21 in the closed state, reducing vibration and displacement. The sealing element 3 can be an elastic element such as silicone rubber, which can play a buffering and protective role between the blocking element 21 and the inner liner 200, reducing vibration and impact, avoiding wear or noise caused by direct hard contact between the blocking element 21 and the inner liner 200, and extending service life.

[0045] In the illustrated embodiment, the sealing element 3 includes a first sealing section 31 and a second sealing section 32 and a third sealing section 33 respectively disposed at both ends of the first sealing section 31. The first sealing section 31 fits against the inner wall of the opening 201, and the second sealing section 32 and the third sealing section 33 fit against the inner edge and outer edge of the opening 201 respectively, so as to fix the sealing element 3 to the inner liner 200. In the closed state, the blocking member 21 abuts against the third sealing section 33. Of course, in other embodiments, the sealing element 3 may only include the third sealing section 33, or only include the first sealing section 31 and the third sealing section 33; and the sealing element 3 may also be fixedly connected to the inner liner 200 by other methods such as interference fit, adhesive, snap-fit, fasteners, etc., as long as the stability and reliability of the connection between the two are ensured. This embodiment of the present invention does not impose specific limitations here.

[0046] like Figures 2 to 3 As shown, in one embodiment, the temperature measuring device 100 further includes a bracket 4, which is disposed on the outer wall of the inner liner 200. The temperature measuring element 1 and the shielding assembly 2 are both disposed on the bracket 4. The bracket 4 supports and fixes the temperature measuring element 1 and the shielding assembly 2, so that the temperature measuring device 100 can be fixed to the inner liner 200 as a whole, simplifying the assembly steps and ensuring the relative positional accuracy between the temperature measuring element 1, the shielding assembly 2 and the opening 201. The bracket 4 can be directly fixed to the outer wall of the inner liner 200 by screws, clips, adhesives, etc., or it can be fixed to the outer shell of the cooking equipment or other connecting parts. Of course, in other embodiments, the temperature measuring element 1 and the shielding assembly 2 can also be fixed separately to the outer wall of the inner liner 200, the outer shell of the cooking equipment or other connecting parts.

[0047] Furthermore, the temperature measuring device 100 can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the temperature measuring device 100 to perform corresponding operations, thereby realizing intelligent control of the temperature measuring device 100 and improving the user experience.

[0048] like Figure 1 As shown, this embodiment of the present invention also provides a cooking device, including an inner liner 200 and the aforementioned temperature measuring device 100, wherein an opening 201 is provided on the wall of the inner liner 200. The cooking device can be a steam oven, a steam oven / microwave oven, or other equipment with functions that generate a lot of moisture during cooking, such as steaming, or it can be an oven, a microwave oven, or other equipment.

[0049] like Figure 3As shown, in one embodiment, the inner pot 200 further includes a flange 202 extending outward from the edge of the opening 201, the height H of which is between 3mm and 6mm. H can be any value within the range of 3mm to 6mm, such as 3mm, 4mm, 5mm, or 6mm. The flange 202 serves as a microwave shield, reducing microwave energy leakage from the opening 201 during microwave cooking and improving safety. H ≥ 3mm ensures the microwave shielding effect of the flange 202; H ≤ 6mm prevents the flange 202 from being too large, thus avoiding an excessively large overall size of the cooking appliance. Furthermore, the outward extension of the flange 202 prevents it from being visible from inside the inner pot 200, improving aesthetics. Of course, in other embodiments, the flange 202 can also extend inward from the edge of the opening 201; or part of the flange 202 extends outward from the edge of the opening 201, and part of the flange 202 extends inward from the edge of the opening 201.

[0050] Furthermore, the sealing element 3 includes a first sealing section 31 and a second sealing section 32 and a third sealing section 33 respectively disposed at both ends of the first sealing section 31. The first sealing section 31 is fitted with the inner wall of the opening 201 and the flange 202, and the second sealing section 32 and the third sealing section 33 are fitted with the inner edge of the opening 201 and the outer edge of the flange 202 respectively, so as to fix the sealing element 3 to the inner liner 200.

[0051] like Figures 1 to 3 As shown, in one embodiment, the inner pot 200 includes a top wall 203, a rear wall 204, and an inclined section 205 connecting the top wall 203 and the rear wall 204, with an opening 201 located on the inclined section 205. The opening 201, located on the inclined section 205 near the top of the inner pot 200, allows the temperature measuring element 1 to be better aligned with the food surface in the middle or bottom of the inner pot 200, thereby obtaining a more accurate temperature signal and improving temperature measurement accuracy. Simultaneously, the temperature measuring device 100 can utilize underutilized space within the cooking equipment, avoiding interference with other structures within the cooking equipment such as heating elements, lighting elements, and air ducts. Of course, in other embodiments, the opening 201 can also be located on the top wall 203 or the rear wall 204 as needed; alternatively, the inner pot 200 may also include a side wall 206, and the opening 201 can also be located on the side wall 206, at the connection between the side wall 206 and the top wall 203, or at the connection between the side wall 206 and the rear wall 204.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0053] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
