Description

[0002] At present, the heating mode of cooking utensil mainly has hot plate and electromagnetic induction heating, and the two heating modes all heat metal inner pot first and then conduct heat to water in the pot through heat conduction, and then cook food materials. The heating mode of heat conduction generally has the problems of uneven heating of food materials and low cooking efficiency.

[0003] In order to achieve the effect of rapid and uniform heating, microwave rice cookers appear on the market, which directly heat water by using the principle of microwave penetration heating. The temperature sensor of the traditional microwave rice cooker adopts a contact sensor, and can only judge the temperature by the water vapor generated during the cooking process. When reheating food, there is no large amount of water vapor generated, so the food temperature can only be controlled by controlling the heating time, and the temperature of the heated food is prone to be too low or too high. Therefore, some microwave rice cookers replace the contact temperature sensor with an infrared sensor, which can directly detect the temperature of the food surface when reheating food. However, the water vapor generated during the cooking process will condense water on the filter of the infrared sensor, thereby reducing the temperature measurement accuracy of the cooked food, which is prone to overflow and also affects the temperature measurement accuracy of the reheated food, which is not conducive to accurate heating of the food.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features. In addition, "and / or" or "and / or" appearing throughout the text means that the three parallel schemes are included, for example, "A and / or B" includes A scheme, or B scheme, or A and B simultaneously satisfy the scheme. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of a person skilled in the art, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist and is not within the protection scope required by the present application.

[0033] In the related art, the non-contact temperature sensor at the upper cover of the microwave rice cooker is replaced by an infrared sensor, so that the temperature of the food surface can be directly detected when reheating the food. However, the water vapor generated during the cooking process will cause condensation on the filter of the infrared sensor, which will reduce the temperature measurement accuracy of the cooked food, is easy to overflow, and also affects the temperature measurement accuracy of the reheated food, which is not conducive to the accurate heating of the food.

[0034] Based on the above problems, the present application aims to provide a cooking appliance 100, which aims to avoid the temperature measurement end of the infrared temperature measurement device 3 being blocked by condensation when cooking food, affecting the accuracy of temperature measurement.

[0035] Please refer to Figures 1 to 3As shown, the cooking utensil 100 in the embodiment of the present application comprises a pot body assembly 1, an inner pot 4, a cover 2 and an infrared temperature measuring device 3. The pot body assembly 1 is provided with a microwave cavity 121. The inner pot 4 is detachably placed in the microwave cavity 121. The inner pot 4 is provided with a cooking cavity 41 for containing food to be cooked. The cover 2 is movably connected to the pot body assembly 1. The cover 2 is used to cover the microwave cavity 121 and the cooking cavity 41. The infrared temperature measuring device 3 is arranged on the pot body assembly 1. The infrared temperature measuring device 3 is used to detect the temperature of the food in the microwave cavity 121 or the inner pot 4.

[0036] In the embodiment, the pot body assembly 1 is provided with the microwave cavity 121 and can release microwaves into the microwave cavity 121 to heat or cook food. When the cooking utensil 100 is used to heat or reheat some dry food, the food does not need to be placed in the heating cavity of the inner pot 4 for heating. Therefore, when the food is heated, the inner pot 4 can be removed from the microwave cavity 121. The food can be placed in the microwave cavity 121 directly or through a dish. Then, the cover 2 is covered on the microwave cavity 121 of the pot body assembly 1. The pot body assembly 1 heats the food by microwaves. The infrared temperature measuring device 3 directly measures the temperature of the food. The pot body assembly 1 controls the microwave heating time and heating temperature according to the temperature measurement result, so as to avoid the temperature of the food being heated too high or too low.

[0037] When the cooking utensil 100 is used to cook food, the food to be cooked can be placed in the cooking cavity 41 of the inner pot 4. The inner pot 4 is placed in the microwave cavity 121. Then, the cover 2 is covered on the microwave cavity 121 and the cooking cavity 41. The pot body assembly 1 can cook the food in the cooking cavity 41 by microwaves. At this time, the infrared temperature measuring device 3 arranged on the pot body assembly 1 can indirectly measure the temperature of the food in the cooking cavity 41 by measuring the temperature of the inner pot 4. Then, the cooking utensil 100 can control the cooking time according to the temperature measurement result. The infrared temperature measuring device 3 is arranged on the pot body assembly 1. The cover 2 is covered on the cooking cavity 41. Therefore, the water vapor generated by the food in the cooking cavity 41 cannot flow between the inner pot 4 and the pot body assembly 1. In this way, the water vapor in the cooking cavity 41 cannot condense on the temperature measuring end of the infrared temperature measuring device 3, so as to avoid affecting the accuracy of the temperature measurement of the infrared temperature measuring device 3.

[0038] In addition, when the inner pot 4 is transparent, the infrared temperature measuring device 3 can directly measure the temperature of the food in the inner pot 4 by penetrating the inner pot 4. The cooking utensil 100 controls the cooking time or the heating time and heating temperature according to the temperature measurement result. The inner pot 4 can be transparent glass or transparent plastic material suitable for microwave heating.

[0039] It can be understood that the cooking utensil 100 can realize the conventional functions of the rice cooker, such as cooking rice, cooking soup and cooking porridge, by microwave cooking the food in the inner pot 4, and the cooking utensil 100 can realize the conventional microwave oven heating function by microwave heating the food placed in the dish in the microwave cavity 121. Alternatively, one end of the cover body 2 can be connected to the pot body assembly 1 through a hinge mechanism, and the other end of the cover body 2 is provided with a door hook, and the pot body assembly 1 is provided with a interlocking mechanism corresponding to the door hook, the cover body 2 is rotatably connected to the pot body assembly 1 through the hinge mechanism, and the cover body 2 can be covered on the cavity opening of the microwave cavity 121 or opened by rotating, when the cover body 2 is covered on the cavity opening of the microwave cavity 121, the door hook of the cover body 2 is locked and matched with the interlocking mechanism, so as to ensure that the microwave cavity 121 is in a stable closed state.

[0040] In an embodiment of the present application, as shown in Figure 3 The infrared temperature measuring device 3 is arranged on the side of the pot body assembly 1, and the temperature measuring end of the infrared temperature measuring device 3 is arranged towards the bottom wall of the microwave cavity 121.

[0041] In this embodiment, the infrared temperature measuring device 3 can measure the temperature of the food surface on the bottom of the microwave cavity 121 from top to bottom, so as to ensure that the infrared temperature measuring device 3 has a large enough temperature measuring coverage range, and ensure the accuracy of measuring the temperature of the reheated food, so that the cooking utensil 100 can accurately heat the food, and avoid that the final heating temperature of the food is too high or too low, which does not meet the user's requirements.

[0042] It can be understood that the central axis of the temperature measuring end of the infrared temperature measuring device 3 is arranged at an angle with the central axis of the microwave cavity 121, and the temperature measuring coverage range of the infrared temperature measuring device 3 can be changed by adjusting the central axis of the infrared temperature measuring device 3 and the angle, which can be set according to actual needs during the production of the cooking utensil 100.

[0043] In an embodiment of the present application, as shown in Figure 3As shown, the angle a between the central axis of the temperature measuring end of the infrared temperature measuring device 3 and the central axis of the microwave cavity 121 satisfies: 30°≤a≤89°. At this time, the infrared temperature measuring device 3 can cover most of the area of the microwave cavity 121. If the angle a is too small, the temperature measuring range of the infrared temperature measuring device 3 cannot cover the end of the microwave cavity 121 away from the infrared temperature measuring device 3, and the infrared temperature measuring device 3 cannot complete the temperature measurement of the food with a large volume. If the angle a is too large, the infrared temperature measuring device 3 cannot cover the bottom of the microwave cavity 121, and cannot measure the temperature of the food with a small volume. Alternatively, the angle a between the central axis of the infrared temperature measuring device 3 and the central axis of the microwave cavity 121 can be 30°, 40°, 45°, 50°, 60° or 70°, etc., which is not specifically limited here. It can be understood that the field of view angle of the infrared temperature measuring device 3 is generally between 30° and 120°, and the angle between the central axis of the temperature measuring end of the infrared temperature measuring device 3 and the central axis of the microwave cavity 121 can be set according to the field of view angle of the infrared temperature measuring device 3.

[0044] In an embodiment of the present application, as shown in Figure 3 As shown, the pot body assembly 1 includes an outer shell 11 and a cavity 12, the outer shell 11 surrounds the cavity 12, the outer shell 11 and the cavity 12 form a mounting cavity 111, and the cavity 12 forms a microwave cavity 121; the infrared temperature measuring device 3 is arranged in the mounting cavity 111, the cavity 12 is provided with a through hole communicating the mounting cavity 111 and the microwave cavity 121, and the temperature measuring end of the infrared temperature measuring device 3 is arranged corresponding to the through hole.

[0045] In this embodiment, the infrared temperature measuring device 3 is not arranged in the microwave cavity 121, but is arranged in the mounting cavity 111 formed by the outer shell 11 and the cavity 12, so that the infrared temperature measuring device 3 can be isolated from the food in the microwave cavity 121, avoiding the moisture, oil or debris of the food from entering or contaminating the infrared temperature measuring device 3, thereby reducing the failure rate of the infrared temperature measuring device 3 and improving the service life of the infrared temperature measuring device 3. The infrared temperature measuring device 3 can be connected to the outer shell 11 or the cavity 12 by bolt connection or buckle structure, etc. which can be detached, which is not specifically limited here. The cavity 12 is provided with a through hole communicating the microwave cavity 121, and the temperature measuring end of the infrared temperature measuring device 3 can measure the temperature of the inner pot 4 or the reheated food in the microwave cavity 121 through the through hole. The size of the through hole is consistent with the cross-sectional size of the temperature measuring end of the infrared temperature measuring device 3, so as to avoid the outer shell 11 from shielding the infrared temperature measuring device 3.

[0046] In actual implementation, the outer shell 11 can be made of plastic material and play a role in appearance decoration; the cavity 12 can be made of metal material such as galvanized metal or stainless steel which can prevent microwave transmission, and the cavity 12 plays a role in structural support and can also prevent the microwave in the microwave cavity 121 from radiating outward. The outer shell 11 and the cavity 12 are connected by mechanical fasteners such as rivets or bolts, or are connected by adhesives, or are connected by buckle clamping, which is not specifically limited here.

[0047] It can be understood that the infrared temperature measuring device 3 includes a mounting shell, a control circuit board, a detection probe and a filter sheet, the control circuit board and the detection probe are arranged in the mounting shell, the detection probe is arranged as a temperature measuring end of the infrared temperature measuring device 3 and is connected with the control circuit board, the control circuit board is used for acquiring a detection temperature of the detection probe, the control circuit board can be electrically connected with a control module of the cooking utensil 100 to send the detection temperature to the control module, so that the cooking utensil 100 can adjust a microwave time and a microwave power according to the detection temperature. The mounting shell is provided with a via hole corresponding to the detection probe and the through hole, the via hole and the through hole are coaxially arranged, and the detection probe detects the temperature of the food in the microwave cavity 121 through the via hole and the through hole. The filter sheet covers the through hole, the filter sheet can selectively absorb or filter off light of a specific wavelength, only allows light of a specific wavelength to pass, and thus improves the accuracy of infrared temperature measurement of the infrared temperature measuring device 3. At the same time, the arrangement of the filter sheet also avoids that water vapor, food oil or debris in the microwave cavity 121 enters the mounting cavity 111 through the through hole to affect the normal work of the infrared temperature measuring device 3.

[0048] In actual implementation, the filter sheet can be connected to the cavity 12 by a sealing ring or a gluing manner to ensure the sealing effect between the filter sheet and the cavity 12.

[0049] In an embodiment of the present application, as shown in Figure 3 The cavity 12 is close to one side of the shell 11 to form a mounting groove 122, and the infrared temperature measuring device 3 is arranged in the mounting groove 122, and the groove wall of the mounting groove 122 is provided with a through hole.

[0050] In the embodiment, the cavity 12 is provided with the mounting groove 122 for arranging the infrared temperature measuring device 3, and the infrared temperature measuring device 3 is arranged in the mounting groove 122, so as to facilitate the positioning and installation of the infrared temperature measuring device 3, and also provide a certain limit for the infrared temperature measuring device 3, so as to reduce the possibility of displacement of the infrared temperature measuring device 3 relative to the cavity 12 and ensure the stability of the infrared temperature measuring device 3.

[0051] In actual implementation, during the production process of the cooking utensil 100, the angle of the groove wall of the mounting groove 122 abutting against the temperature measuring end of the infrared temperature measuring device 3 relative to the bottom wall of the microwave cavity 121 can be changed to change the included angle between the central axis of the infrared temperature measuring device 3 and the central axis of the microwave cavity 121.

[0052] It can be understood that the cavity 12 has a bottom wall and a side wall connected with the bottom wall, the mounting groove 122 is arranged on the side wall and is recessed into the microwave cavity 121 from the side wall, so as to avoid that other parts of the side wall shield the temperature measuring end of the infrared temperature measuring device 3. The bottom wall and the side wall surround to form the microwave cavity 121, and the microwave cavity 121 can be arranged in a cylindrical shape or a cubic shape or a cuboid shape, etc. The bottom wall is formed with a groove for positioning and placing the inner pot 4.

[0053] In an embodiment of the present application, as shown in Figure 3 The groove wall of the mounting groove 122 includes a first groove wall 1221, a second groove wall 1222, a third groove wall and a fourth groove wall. The first groove wall 1221 is connected with the second groove wall 1222 at an included angle. The third groove wall and the fourth groove wall are respectively located on two sides of the first groove wall 1221 and are connected with the first groove wall 1221 and the second groove wall 1222. The first groove wall 1221 is located on the side of the second groove wall 1222 close to the bottom wall of the microwave cavity 121 and is provided with a through hole. The temperature measuring end of the infrared temperature measuring device 3 abuts against the first groove wall 1221.

[0054] In the present embodiment, the mounting groove 122 is provided in a triangular prism shape. The first groove wall 1221 and the second groove wall 1222 form the side surface of the triangular prism. The third groove wall and the fourth groove wall form the bottom surface of the triangular prism. When the infrared temperature measuring device 3 is installed in the mounting groove 122, the temperature measuring end of the infrared temperature measuring device 3 abuts against the first groove wall 1221. The first groove wall 1221 is arranged in parallel with the end surface of the temperature measuring end of the infrared temperature measuring device 3. Therefore, the plane where the through hole is located is also arranged in parallel with the end surface of the temperature measuring end of the infrared temperature measuring device 3. In this way, the temperature measuring end of the infrared temperature measuring device 3 is prevented from being shielded by the first groove wall 1221.

[0055] Meanwhile, the abutting arrangement of the temperature measuring end of the infrared temperature measuring device 3 and the first groove wall 1221 also makes the temperature measuring end of the infrared temperature measuring device 3 be arranged obliquely towards the bottom wall of the microwave cavity 121. The included angle between the central axis of the temperature measuring end of the infrared temperature measuring device 3 and the central axis of the microwave cavity 121 can be determined according to the included angle between the first groove wall 1221 and the bottom wall of the microwave cavity 121. The infrared temperature measuring device 3 is in abutting relationship with the second groove wall 1222, the third groove wall and the fourth groove wall. This facilitates the positioning and installation of the infrared temperature measuring device 3 and makes the temperature measuring end of the infrared temperature measuring device 3 and the through hole be more easily aligned.

[0056] In an embodiment of the present application, as shown in Figure 3 The maximum depth d of the mounting groove 122 satisfies d≤20mm.

[0057] In the present embodiment, the mounting groove 122 is recessed from the cavity 12 towards the microwave cavity 121. That is, the cavity 12 is arranged protruding into the microwave cavity 121 at the position of the mounting groove 122. Therefore, in order to prevent the inner pot 4 from colliding with the protruding part of the cavity 12 during the process of being placed in the microwave cavity 121, the maximum depth of the mounting groove 122 is not greater than 20mm. The maximum depth of the mounting groove 122 refers to the maximum amount of protruding into the microwave cavity 121 from the bottom wall of the mounting groove 122, as shown in Figure 3As shown in Fig. 12, the installation groove 122 can be 10 mm, 15 mm or 20 mm, etc., and the specific depth of the installation groove 122 can be set according to the size of the infrared temperature measuring device 3. It can be understood that, except for the part of the side wall of the cavity 12 that is vertically arranged with the bottom wall of the cavity 12, the angle between the side wall of the inner pot 4 and the bottom wall of the inner pot 4 is greater than 90°, so that there is a certain space between the side wall of the inner pot 4 and the side wall of the cavity 12, so that the side wall of the cavity 12 is recessed into the microwave cavity 121 to form the installation groove 122.

[0058] In an embodiment of the present application, the shell 11 is provided with a clamping seat, the clamping seat is provided with a clamping hole, the infrared temperature measuring device 3 is provided with a clamping protrusion corresponding to the clamping hole, and the clamping protrusion is detachably limited in the clamping hole, so that the infrared temperature measuring device 3 is detachably arranged in the clamping seat.

[0059] In the present embodiment, the infrared temperature measuring device 3 is limited and matched with the clamping hole on the clamping seat through buckling, so as to realize the detachable connection of the infrared temperature measuring device 3 and the shell 11, thereby facilitating the disassembly and assembly of the infrared temperature measuring device 3 during replacement.

[0060] It can be understood that the clamping protrusion is arranged on the outer wall of the installation shell in the infrared temperature measuring device 3, the clamping seat is surrounded to form an installation space, and when the infrared temperature measuring device 3 is installed in the installation space, the clamping protrusion of the installation shell is limited in the clamping hole, so as to realize the detachable connection of the infrared temperature measuring device 3. The clamping protrusion and the clamping hole can be correspondingly provided in multiple groups, and the multiple groups of clamping protrusions and clamping holes can be arranged around the circumferential side of the infrared temperature measuring device 3, so as to ensure the installation stability of the infrared temperature measuring device 3.

[0061] In actual implementation, the clamping seat can be connected to the shell 11 through bolts or rivets, and the clamping seat can also be arranged on the cavity 12, which is not limited here.

[0062] In an embodiment of the present application, the cooking utensil 100 further comprises a microwave generating module 5 and a waveguide module 6, the microwave generating module 5 and the waveguide module 6 are arranged in the installation cavity 111, the waveguide module 6 is connected to the output end of the microwave generating module 5 and connected with the cavity 12.

[0063] In the present embodiment, the microwave generating module 5 generates microwaves which are coupled into the microwave cavity 121 through the waveguide module 6, so as to perform microwave heating on the food in the microwave cavity 121. The microwave generating module 5 comprises a power supply and a magnetron, the power supply provides high voltage to the magnetron, and the magnetron continuously generates microwaves under the excitation of the power supply. The waveguide module 6 transmits microwaves into the microwave cavity 121, and then heats or cooks the food in the microwave cavity 121.

[0064] In an embodiment of the present application, as shown in Fig. 14, the waveguide module 6 comprises a waveguide 61 and a waveguide cover 62, the waveguide cover 62 is arranged on the waveguide 61, and the waveguide cover 62 is provided with a waveguide hole 621 corresponding to the waveguide 61. Figure 1 and Figure 3As shown, the cover 2 covers the microwave cavity 121, and forms a microwave space 7 with the pot body assembly 1, and the distance h between the temperature measuring end of the infrared temperature measuring device 3 and the bottom wall of the microwave cavity 121 and the height distance H of the microwave space 7 satisfy: 1 / 3≤h / H<4 / 5.

[0065] In the embodiment, the setting height h of the infrared temperature measuring device 3 is determined according to the height H of the microwave space 7, so as to avoid that the setting height of the infrared temperature measuring device 3 is too low or too high. If the setting height of the infrared temperature measuring device 3 is too low, the reheated food itself may block the temperature measuring range of the infrared temperature measuring device 3, so that the infrared temperature measuring device 3 can only measure the temperature of part of the surface of the reheated food from one side, and cannot measure the temperature of the surface of the reheated food from top to bottom. If the setting height of the infrared temperature measuring device 3 is too high, the infrared temperature measuring device 3 may not be able to detect the surface temperature of the food close to itself in the microwave cavity 121, and it is necessary to reduce the center axis of the temperature measuring end of the infrared temperature measuring device 3 and the center axis of the microwave cavity 121 or increase the field angle of the infrared temperature measuring device 3, which increases the assembly difficulty and cost.

[0066] In some embodiments, as shown in FIG. 1, the inner pot 4 is arranged in the microwave cavity 121, and the infrared temperature measuring device 3 is arranged on the inner pot 4. Figure 3 As shown, the cross-sectional area of the inner pot 4 gradually decreases from one end away from the cavity opening of the cooking cavity 41 to one end close to the cavity opening of the cooking cavity 41, so that the inner pot 4 is closer to the side wall of the microwave cavity 121 as it is closer to the cavity opening of the microwave cavity 121. If the setting height of the infrared temperature measuring device 3 is too high, it may affect the placement of the inner pot 4 or the inner pot 4 may collide with the infrared temperature measuring device 3 when placed.

[0067] The above description is only an exemplary embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation or direct / indirect application in other related technical fields within the technical concept of the present application and the content of the present application are included in the patent protection scope of the present application.
