[0001] The utility model belongs to the field of household appliances, and in particular relates to a cooking utensil with accurate temperature measurement. Background Art

[0002] In order to better control the cooking process and improve the cooking effect, cooking appliances such as rice cookers and pressure cookers usually have a temperature measuring device on the lid to indirectly measure the temperature of the food by detecting the steam temperature in the cooking cavity. However, the steam temperature is often different from the temperature of the food. The measured value of the temperature measuring device cannot reflect the temperature of the food in the cooking cavity, and the measurement result is inaccurate.

[0003] For this reason, a temperature measuring device using a contact-coupled temperature measuring probe has appeared in the prior art, one end of which is plugged and coupled with a coupler provided on the pot cover, and the other end is extended into the cooking cavity to contact the food or water, so that the temperature measuring probe can directly measure the temperature of the food. However, due to the long exposed length of the temperature measuring device, when in use, especially when the cover is opened, the temperature measuring device is prone to collision with other objects, resulting in damage to the contacts of the coupler. In addition, when the user forgets to install the temperature measuring device and the coupler is exposed to steam, or when the user removes the temperature measuring device to clean the pot cover, the contacts of the coupler are prone to oxidation and other problems, which in turn reduces the reliability of the temperature measuring device. Therefore, it also has the problem of inaccurate measurement results. Utility Model Content

[0028] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

[0031] In the present utility model, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "implementation method", "example", "one embodiment", "example" or "specific example" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0032] refer to Figure 1 , Figure 2 and Figure 6 The present embodiment provides a cooking utensil with accurate temperature measurement, comprising a pot body 100 with an inner pot 101 and a pot cover 200 covered on the pot body 100, the cooking utensil further comprising a temperature measuring device 300, the temperature measuring device 300 being detachably connected to the pot cover 200 by magnetic attraction, a wireless transmitter 310 being provided at one end of the temperature measuring device 300 close to the pot cover 200, and a temperature sensing element being provided at the other end extending below the liquid level in the inner pot, a wireless receiver 210 being provided in the pot cover 200, the temperature sensing element being electrically connected to the wireless transmitter 310, and a temperature measurement signal being wirelessly transmitted between the wireless transmitter 310 and the wireless receiver 210.

[0033] Specifically, a power board connected to the wireless receiving device 210 and supplying power to it is provided on the pot cover 200 or the pot body 100. The wireless transmitting device 310 is coupled with the wireless receiving device 210 to obtain electrical energy, so that the temperature measurement signal of the temperature sensing element can be wirelessly transmitted to the wireless receiving device 210 through the wireless transmitting device 310 electrically connected thereto, thereby realizing smooth transmission of the signal.

[0034] It should be noted that the “extending below the liquid level in the inner pot” means that after the temperature measuring device 300 is attracted to the pot cover 200, in the vertical direction, its lower end is not higher than the maximum water level line of the inner pot and does not interfere with the inner wall of the inner pot. Within this range, technical personnel in this field can make a selection based on actual conditions.

[0035] In this embodiment, the end of the temperature measuring device 300 with the temperature sensing element is extended below the liquid surface, so that the temperature sensing element can directly measure the temperature of the food or the liquid in the inner pot, and the temperature measurement is faster and more accurate. In addition, compared with the method of realizing signal transmission by mutual plug-in coupling, the temperature measurement signal of the temperature sensing element of this embodiment is wirelessly transmitted to the wireless receiving device 210 through the wireless transmitting device 310 electrically connected thereto, and the wireless receiving device 210 is arranged in the pot cover 200 and is not exposed to the outside, thereby reducing the possibility of damage to the wireless receiving device 210. Even if the user forgets to install the temperature measuring device 300, the temperature measuring signal of the temperature sensing element 310 is not exposed to the outside. 0 or removing the temperature measuring device 300 to clean the pot cover 200 will not affect the wireless receiving device 210, thereby improving the reliability of the temperature measuring device 300. At the same time, the temperature measuring device 300 of this embodiment is detachably connected to the pot cover 200 through magnetic attraction. On the one hand, the user does not need a specific installation direction, and only needs to align the two automatically with the help of adsorption force, which is more convenient to use. On the other hand, even if the temperature measuring device 300 collides, it is not easy to damage the wireless receiving device 210 in the pot cover 200, thereby further ensuring the accuracy of the temperature measuring device 300.

[0036] Furthermore, the pot cover 200 and the pot body 100 can be hinged or separately set. When the pot body and the pot cover are connected by a hinge, the temperature measuring device 300 will rotate around the hinge with the pot cover 200 during the opening process. Preferably, the radius of the maximum trajectory circle formed by the temperature measuring device 300 with the hinge as the center is R, and the shortest distance between the inner side surface of the inner liner away from the hinge and the hinge is L, and R is less than L, so that during the process of flipping the pot cover to open and close, the temperature measuring device 300 and the inner side surface of the inner liner away from the hinge always maintain a certain distance, avoiding the problem that the user needs to remove the temperature measuring device before continuing to open the lid due to interference between the temperature measuring device 300 and the inner liner 101 during the opening process, thereby improving the user experience.

[0037] The utility model does not specifically limit the method of magnetic attraction. A magnetic metal can be set on the temperature measuring device 300 and a magnet such as a magnet can be set on the pot cover 200. A magnet can be set on the temperature measuring device 300 and a magnetic metal can be set on the pot cover 200. Magnets can also be set on both the temperature measuring device 300 and the pot cover 200. Those skilled in the art can make a choice according to actual conditions.

[0038] In some embodiments of the present invention, reference Figure 2 and Figure 3 The pot cover 200 includes a lining cover 201 and an inner cover 202 detachably fixed to the lining cover 201 . The inner cover 202 is provided with a through hole 203 . One end of the temperature measuring device 300 close to the pot cover passes through the through hole 203 and is magnetically connected to the lining cover 201 .

[0039] The through hole 203 can give the user an explicit prompt, making the installation of the temperature measuring device 300 more convenient and improving the user's experience. In addition, the hole wall of the through hole 203 can also play a certain supporting and limiting role for the temperature measuring device 300, making the magnetic attraction cooperation between the temperature measuring device 300 and the lining cover 201 more stable. At the same time, the temperature measuring device 300 passes through the through hole 203 and is magnetically connected to the lining cover 201, which can make the wireless transmitting device 310 in the temperature measuring device 300 closer to the wireless receiving device 210 in the pot cover 200, thereby reducing the design requirements for the wireless transmitting device, the wireless receiving device and the pot cover, which is conducive to reducing production costs.

[0040] Of course, in some alternative embodiments, it is also possible not to open a hole on the inner cover 202, so that the end of the temperature measuring device 300 close to the pot cover is magnetically connected to the inner cover 202, which is not limited here.

[0041] The present invention does not limit the installation position of the temperature measuring device 300. In a specific embodiment, refer to Figure 2 , Figure 3 and Figure 4 The lining cover 201 is provided with a second temperature measuring device 220, and the second temperature measuring device 220 has a temperature measuring probe 221. The temperature measuring device 300 is provided with a socket 331 for inserting the temperature measuring probe 221 at one end close to the pot cover.

[0042] The cooperation between the temperature measuring probe 221 and the socket 331 can assist in docking, which is beneficial to improving the efficiency of magnetic docking and the user's experience. At the same time, such a dual temperature measuring device provides users with more choices. When the temperature measuring device 300 is magnetically matched with the pot cover 200, the user can use the temperature measuring device 300 for cooking, and the temperature measuring probe 221 can also be protected by the socket 331 to prevent it from being contaminated or damaged. When the user forgets to place the temperature measuring device 300 or the temperature measuring device 300 is lost, that is, the temperature measuring device 300 is not magnetically matched with the pot cover 200, the wireless receiving device 210 in the pot cover 200 cannot receive the temperature measurement signal, and the cooking utensil automatically switches to using the second temperature measuring device 220 for cooking to avoid the situation where cooking cannot be done.

[0043] It should be noted that the present embodiment does not limit the specific position of the magnetically coupled temperature measuring device 300 and the pot cover 200. Figure 2 As shown, it cooperates with the lining cover 201 and can cooperate with the inner cover 202. Those skilled in the art can make a selection according to actual conditions.

[0044] It can be understood that in some alternative embodiments, the matching position of the temperature measuring device 300 and the pot cover 200 can also be set at other positions except the second temperature measuring device 220, or only the temperature measuring device 300 is set without setting the second temperature measuring device 220; of course, the temperature measuring device can also be set at other positions of the cooking utensil, such as below the inner pot 101, which is not limited here.

[0045] In a specific embodiment, referring to Figure 2 The temperature measuring device 300 is provided with a first magnetic component 350 at one end close to the pot cover, and the lining cover 201 is provided with a sealing component 230 and a second magnetic component 240 corresponding to the through hole 203. The sealing component 230 is arranged around the through hole 203, and the temperature measuring device 300 extends into the sealing component 230, and the first magnetic component 350 and the second magnetic component 240 are attracted.

[0046] The seal 230 surrounding the through hole 203 can form a semi-enclosed cavity between the seal 230 and the inner cover 202. The cavity has an opening only at the through hole 203. The air therein is not easy to be discharged, and the air pressure is relatively stable. When the bubbles generated during the cooking process reach the through hole 203 from bottom to top, they will be affected by factors such as the air in the cavity and their own volume and are difficult to continue to squeeze upward into the cavity, thereby reducing the probability of the bubbles entering the cavity and contacting the temperature measuring device 300. At the same time, it also makes it difficult for external substances such as steam and soup leaking from the steam valve position to enter the cavity from the outside, thereby helping to improve the transmission efficiency of the signal and ensure the accuracy of the temperature measurement. In addition, the seal 230 can also play a certain protective and buffering role for the temperature measuring device 300 extending therein, reducing the probability of the temperature measuring device 300 being damaged due to collision during assembly or use, and increasing its service life.

[0047] Preferably, the sealing member 230 is a sealing member at the second temperature measuring device 220, that is, the temperature measuring device 300 and the second temperature measuring device 220 share a sealing member, so as to reduce the number of parts, simplify the design of the pot cover, and reduce the production cost.

[0048] The present invention does not specifically limit the form and position of the first magnetic member 350 and the second magnetic member 240, as long as the two can be attracted. Figure 2 A mounting hole with an annular rib is provided on the lining cover 201, the second magnetic component 240 is arranged around the outer periphery of the annular rib, the wireless receiving device 210 is located on the outer side of the second magnetic component 240, an outer flange is provided on the upper end of the sealing component 230, the outer flange is plugged into the annular rib, and the second temperature measuring device 220 and the annular rib jointly clamp the upper end of the sealing component 230.

[0049] In some embodiments of the present invention, reference Figure 2 , Figure 3 and Figure 4 The temperature measuring device 300 includes a housing 320 and a cover 330. The housing 320 has a large diameter section 321 and a small diameter section 322 located below the large diameter section 321. The cover 330 and the large diameter section 321 enclose a cavity 360 for accommodating the wireless transmitting device 310. The temperature sensing element is arranged in the small diameter section 322. The large diameter section 321 leaves sufficient space for accommodating the wireless transmitting device 310, while the small diameter section 322 can reduce the volume of the temperature measuring device, making it easier to store it, and also facilitate the temperature measuring device to be inserted into food for direct temperature measurement.

[0050] Furthermore, the housing 320 is provided with a turning tooth 323, and the cover 330 is provided with a lap joint 332 corresponding to the turning tooth 323. When assembling, the cover 330 is first covered on the large diameter section 321 of the housing, and then the turning tooth 323 is bent to buckle on the lap joint 332, thereby eliminating the need for screw connection and improving assembly efficiency. Of course, this embodiment does not exclude the housing and the cover from being assembled by screws, clamping, gluing, etc.

[0051] Better, reference Figure 2 The cover body 300 extending into the outer shell 320 is provided with an annular groove on its circumferential side, and a sealing ring is embedded in the annular groove. In this way, when the cover body 300 and the outer shell 320 are assembled, a good seal can be formed between the two, so that the temperature measuring device 300 can be directly put into water for cleaning, thereby improving the cleaning convenience of the temperature measuring device and the user experience.

[0052] In a specific embodiment, referring to Figure 2 The cavity 360 is provided with a support member 340, and the wireless transmitting device 310 is clamped and fixed between the support member 340 and the cover body 330. In this way, the wireless transmitting device 310 can be firmly supported to prevent it from loosening and generating abnormal noise during use.

[0053] Furthermore, the cover body 330 is provided with a recessed portion sunken into the cavity 360, and the inner wall of the recess forms a plug hole 331. The wireless transmitting device 310 is provided with a through hole corresponding to the recess, and the outer wall of the recess can cooperate with the through hole, thereby improving the convenience of assembly and realizing the rapid assembly of the cover body 330 and the shell 320.

[0054] Optional, reference Figure 2 A receiving groove is provided at the lower side of the cover body 330 , and the first magnetic attraction component 350 is embedded in the receiving groove, or the top wall of the receiving groove and the upper surface of the wireless transmitting device 310 clamp the first magnetic attraction component 350 .

[0055] In some embodiments of the present invention, reference Figure 3 and Figure 5The pot cover 200 is provided with a receiving hole 400 for accommodating the temperature measuring device 300 , and a groove 250 is provided on the side of the pot cover 200 . The receiving hole 400 is recessed from the inner wall of the groove 250 into the pot cover 200 .

[0056] The setting of the groove 250 is beneficial to avoiding exposure of the temperature measuring device 300 after being stored, and avoiding interference between the stored temperature measuring device and the pot body when opening and closing the lid. The storage hole 400 is recessed from the inner wall of the groove 250 into the pot lid 200, so that the temperature measuring device can be better protected by the hole wall of the storage hole 400, so that it can be reasonably stored without being easily damaged, thereby improving the reliability of the temperature measuring device 300.

[0057] The present invention does not limit the matching mode between the temperature measuring device and the receiving hole. The temperature measuring device 300 can be simply placed in the receiving hole 400, or a magnetic device can be arranged near the receiving hole 400 so that the temperature measuring device 300 can be adsorbed in the receiving position. Of course, the receiving hole 400 can also be a through hole that penetrates the inner wall of the groove 250, that is, the temperature measuring device 300 passes through the receiving hole and extends into the pot cover 200, which is not limited here.

[0058] In a specific embodiment, at least one side of the groove 250 is provided with a hand-locking position, so that the user can conveniently pull out the temperature measuring device 300 through the hand-locking position, thereby improving the user's usage experience.

[0059] In some embodiments of the present invention, reference Figure 6 The pot body 100 is provided with a storage hole 400 for accommodating the temperature measuring device 300. The pot body 100 includes an outer cover 110 and a middle ring 120 arranged on the upper part of the outer cover 110. The storage hole 400 is recessed from the middle ring 120 to the inside of the outer cover 110, so as to reasonably store the temperature measuring device 300.

[0060] In a specific embodiment, referring to Figure 6 The outer periphery of the storage hole 400 is provided with a water retaining rib 130. During the use of the cooking utensil, water will inevitably accumulate on the middle ring 120 due to condensed water spilling from the pot cover or accidental splashing. The provision of the water retaining rib 130 can reduce the probability of the accumulated water on the middle ring 120 entering the pot body through the storage hole 400 or accumulating in the storage hole 400, thereby improving the sanitary condition of the cooking utensil.

[0061] In some alternative embodiments, the bottom of the storage hole 400 is provided with a drain hole connected to the outside of the pot body to drain the accumulated water in the storage hole to the outside of the pot body to prevent the accumulated water from breeding bacteria and generating odor. Of course, both the water retaining rib 130 and the drain hole can also be provided, which is not limited here.

[0062] It can be understood that the receiving hole 400 is a through hole that passes through the middle ring 120, that is, the temperature measuring device 300 extends into the pot body 100 through the receiving hole, and those skilled in the art can make a selection according to actual conditions.

[0063] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
