Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to a cooking appliance. Background Art

[0002] The temperature measuring element is one of the indispensable important components on the cooking appliance. It is used to detect the temperature inside the pot in real time during the cooking process, and send a signal to the control unit of the cooking appliance according to the measured temperature value, so that the control unit controls the start and stop of the heating device, or adjusts the heating power in real time.

[0003] There are various types of temperature measuring elements. Among them, the infrared temperature measuring element is widely promoted because of its high detection accuracy, low cost, and ability to achieve non-contact temperature measurement. The infrared temperature measuring element is usually arranged on the pot cover. The infrared rays inside the pot can directly pass through the lens and be absorbed by the sensor, thereby detecting the temperature inside the pot.

[0004] However, during the cooking process, the high-temperature steam fills the pot and will liquefy to form water droplets at the infrared temperature measuring element and adhere to the surface of the lens of the infrared temperature measuring element. In addition, since the infrared temperature measuring element is arranged on the pot cover, when the high-temperature gas in the pot surges up to this time, due to the lower temperature of the pot cover, it will also quickly liquefy to form water droplets and adhere to the lens. Once water droplets adhere to the lens, when the infrared rays inside the pot pass through the water droplets, refraction will occur, resulting in the infrared rays not being able to reach the sensor and be sensed by the sensor, thereby reducing the sensitivity and temperature measurement accuracy of the infrared temperature measuring element.

[0005] Moreover, the water droplets themselves will release a certain amount of infrared rays, which will also affect the detection accuracy of the sensor. And as the cooking progresses, more and more water droplets adhere to the lens, so that the detection error of the infrared temperature measuring element will become larger and larger. Summary of the Utility Model

[0006] The utility model provides a cooking appliance to solve the problem that water droplets adhere to the surface of the infrared temperature measuring element during the cooking process, resulting in the infrared rays not being able to be normally transmitted to the sensor, and the detection sensitivity and accuracy of the infrared temperature measuring element are relatively low.

[0007] The technical solution adopted by the utility model is as follows:

[0008] A cooking appliance includes a pot body and a pot cover. The pot cover includes a lining cover and an inner cover placed below the lining cover. It also includes an infrared temperature measuring element arranged between the lining cover and the inner cover. A light-transmitting lens is arranged on the side of the infrared temperature measuring element facing the inner cover. The pot cover also includes a sealing member. The sealing member has an installation portion and a sealing lip located below the installation portion. The installation portion is sleeved on the outer periphery of the infrared temperature measuring element. The sealing lip surrounds to form a sealed space. A water guiding rib protruding downward is arranged on the top wall of the sealed space.

[0009] The cooking appliance of the present utility model further has the following additional technical features:

[0010] The lower edge of the water guiding rib is lower than the position where the light-transmitting lens is located.

[0011] A communication port communicating with the infrared temperature measuring member is provided on the top wall of the sealed space. The light-transmitting lens is arranged in the communication port, and the water guiding rib surrounds the outer periphery of the communication port.

[0012] The edge of the communication port protrudes downward to form the water guiding rib.

[0013] The installation part has an installation channel. The light-transmitting lens is arranged inside the installation channel. The outer peripheral side of the light-transmitting lens cooperates with the installation channel or the infrared temperature measuring member to form an installation chamber isolated from the sealed space above the light-transmitting lens, and the infrared temperature measuring member is arranged in the installation chamber.

[0014] The infrared temperature measuring member includes a main body and a detection part. The main body is fixedly connected with the lining cover, and the main body and the lining cover clamp and fix a sealing member.

[0015] The sealing member further has a fixed flange located above the installation part. The fixed flange is located between the main body and the lining cover so that the main body and the lining cover clamp and fix the fixed flange. The fixed flange has a positioning protrusion, and the lining cover and / or the main body is provided with a positioning groove cooperating with the positioning protrusion.

[0016] The inner cover is provided with a detection port. The lower end of the sealing lip abuts against the inner cover and surrounds the outer periphery of the detection port. The detection port is arranged corresponding to the infrared temperature measuring member up and down.

[0017] One side of the inner cover facing the lining cover is provided with a cooperating sunk table corresponding to the infrared temperature measuring member. The detection port is located in the cooperating sunk table. The bottom wall of the cooperating sunk table has a sealing plane, and the lower end of the sealing lip abuts against the sealing plane for sealing.

[0018] An anti-fog layer is provided on one side of the light-transmitting lens facing the inner cover.

[0019] Due to the adoption of the above technical solutions, the beneficial effects obtained by the present utility model are as follows:

[0020] 1. In the present utility model, the light-transmitting lens is arranged on the side of the infrared temperature measuring member facing the inner cover. The arrangement of the light-transmitting lens can not only enable the infrared rays in the pot to pass through the light-transmitting lens and irradiate to the infrared temperature measuring member on the upper side, and be sensed by the infrared temperature measuring member for temperature detection, but also isolate the water vapor and sundries in the pot to avoid steam, liquid, food residues, etc. reaching the infrared temperature measuring member and causing pollution.

[0021] In addition, the pot lid further includes a seal. The sealing lip of the seal cooperates with the inner lid to enclose a sealed space. The light-transmitting lens is located above the sealed space. The top wall of the sealed space is provided with a water guide rib protruding downward. When the food soup or liquefied condensed water on the inner wall of the sealing lip surges upward along the inner wall of the sealing lip, on the one hand, it can be blocked by the water guide rib and cannot directly reach the light-transmitting lens. On the other hand, the water guide rib protrudes downward, which can guide the liquid to drip downward along the water guide rib. Furthermore, the liquid flowing to the light-transmitting lens is greatly reduced, and the refraction phenomenon that occurs when infrared rays pass through the light-transmitting lens due to the influence of water droplets is reduced, thereby improving the detection sensitivity and accuracy of the infrared temperature measuring component.

[0022] 2. As a preferred embodiment of the present invention, the top wall of the sealed space is provided with a communication port communicating with the infrared temperature measuring component. The light-transmitting lens is disposed in the communication port, and the water guide rib surrounds the outer periphery of the communication port. The steam surging into the sealed space will liquefy to form condensed water after contacting the side wall of the sealed space and adhere to the side wall of the sealed space. At this time, a part of the liquid flows downward along the side wall of the sealed space under the action of gravity and returns to the pot. Another part of the liquid gradually flows upward along the side wall of the sealed space under the upward pushing action of the air flow. When the liquid reaches the outer peripheral side of the communication port on the top wall of the sealed space, it is blocked by the water guide rib and cannot reach the communication port, but will be guided by the water guide rib and drip downward from the water guide rib, so that the water guide rib forms a protection circle on the outer peripheral side of the light-transmitting lens, causing the liquid to drip outside the communication port and unable to flow to the light-transmitting lens inside the communication port.

[0023] 3. As a preferred embodiment of the present invention, the installation part has an installation channel. The light-transmitting lens is disposed inside the installation channel. The outer peripheral side of the light-transmitting lens cooperates with the installation channel or the infrared temperature measuring component to form an installation chamber isolated from the sealed space above the light-transmitting lens. The infrared temperature measuring component is disposed in the installation chamber. After the light-transmitting lens is installed in the installation channel, the outer peripheral side abuts against the inner wall of the installation channel, thereby isolating and sealing the chambers on the upper and lower sides of the light-transmitting lens. The lower chamber is directly communicated with the environment inside the pot, enabling the infrared rays inside the pot to irradiate the light-transmitting lens. The upper chamber is isolated from the environment inside the pot, thus preventing the gas, liquid, and food residues inside the pot from reaching the infrared temperature measuring component. Only the infrared rays can pass through the light-transmitting lens to reach the infrared temperature measuring component. Thereby ensuring the cleanliness of the infrared temperature measuring component and improving the detection accuracy.

[0024] 4. As a preferred embodiment of the present utility model, a mating sunk platform is provided on the side of the inner cover facing the lining cover. The mating sunk platform is provided corresponding to the infrared temperature measuring element, and the detection port is located within the mating sunk platform. The bottom wall of the mating sunk platform has a sealing plane, and the lower end of the sealing lip abuts against and seals with the sealing plane. The mating sunk platform is recessed downward. On the one hand, it can avoid the sealing lip of the seal, and there is sufficient space between the inner cover and the lining cover to accommodate the sealing lip, keeping the sealing lip in good shape and preventing the sealing lip from being overly squeezed and affecting the sealing performance. On the other hand, the lower end of the sealing lip abuts against and seals with the sealing plane within the mating sunk platform. The sealing plane is flatter, abuts more closely with the sealing lip, increases the contact area, and improves the sealing effect.

[0025] 5. As a preferred embodiment of the present utility model, an anti-fog layer is provided on the side of the light-transmitting lens facing the inner cover. The anti-fog layer can further effectively block or weaken the formation of water droplets or water vapor on the surface of the light-transmitting lens, so that the light-transmitting lens can be kept clean at any stage of cooking, thus ensuring the light-transmitting effect, ensuring the sensitivity and accuracy of the infrared temperature measuring element to receive infrared rays, and ensuring accurate temperature measurement.

Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0045] As Figures 1 to 4 shown, a cooking appliance includes a pot body and a pot lid. The pot lid includes a lining lid 1 and an inner lid 2 disposed below the lining lid 1, and further includes an infrared temperature measuring member 3 disposed between the lining lid 1 and the inner lid 2. A light-transmitting lens 4 is disposed on the side of the infrared temperature measuring member 3 facing the inner lid 2. The pot lid further includes a sealing member 5. The sealing member 5 has a mounting portion 51 and a sealing lip 52 located below the mounting portion 51. The mounting portion 51 is sleeved on the outer periphery of the infrared temperature measuring member 3. The sealing lip 52 surrounds to form a sealing space 55. A water guiding rib 54 protruding downward is disposed on the top wall of the sealing space 55.

[0046] In the present utility model, the light-transmitting lens 4 is disposed on the side of the infrared temperature measuring member 3 facing the inner lid 2. The setting of the light-transmitting lens 4 can not only enable the infrared rays in the pot to pass through the light-transmitting lens 4 and irradiate to the upper infrared temperature measuring member 3, which is sensed by the infrared temperature measuring member 3 for temperature detection, but also isolate the water vapor and sundries in the pot to prevent steam, liquid, food residues, etc. from reaching the infrared temperature measuring member 3 and causing pollution.

[0047] In addition, the pot lid further includes a sealing member 5. The sealing lip 52 of the sealing member 5 cooperates with the inner lid 2 to enclose a sealing space 55. The light-transmitting lens 4 is located above the sealing space 55. A water guiding rib 54 protruding downward is disposed on the top wall of the sealing space 55. When the food soup or liquefied condensed water on the inner wall of the sealing lip 52 surges upward along the inner wall of the sealing lip 52, on the one hand, it can be blocked by the water guiding rib 54 and cannot directly reach the light-transmitting lens 4, and on the other hand, the water guiding rib 54 protrudes downward, which can guide the liquid to drip downward along the water guiding rib 54. Thus, the liquid flowing to the light-transmitting lens 4 is greatly reduced, and the refraction phenomenon that occurs when the infrared rays pass through the light-transmitting lens 4 due to the influence of water droplets is reduced, and the detection sensitivity and accuracy of the infrared temperature measuring member 3 are improved.

[0048] It can be understood that the sealed space 55 communicates with the inside of the pot so that the infrared rays inside the pot can irradiate the light-transmitting lens 4, while the sealed space 55 is hermetically isolated from the infrared temperature measuring member 3, so that the gas, liquid and food residues surging up from the inside of the pot into the sealed space 55 cannot reach the infrared temperature measuring member 3.

[0049] Preferably, as Figure 3 , Figure 5 shown, the lower edge of the water guiding rib 54 is lower than the position where the light-transmitting lens 4 is located.

[0050] The function of the water guiding rib 54 is to guide the liquid to flow downward and drip. Therefore, the light-transmitting lens 4 is arranged above the water guiding rib 54, so that the liquid on the inner wall of the sealed space 55 gradually moves away from the light-transmitting lens 4 during the process of contacting the water guiding rib 54 and dripping along the water guiding rib 54, thereby further reducing the risk of the liquid crossing the water guiding rib 54 and reaching the light-transmitting lens 4.

[0051] Preferably, as Figure 3 , Figure 5 shown, the lower end of the water guiding rib 54 is a tip, so that the liquid on the water guiding rib 54 can drip more easily and will not accumulate on the water guiding rib 54 for a long time, thereby improving the guiding efficiency of the water guiding rib 54 for the liquid. At the same time, the tip forms an inclined surface on the side close to the infrared temperature measuring member 3, thereby forming a flared structure at the infrared temperature measuring member 3, which helps to converge the infrared rays irradiated thereto.

[0052] As a preferred embodiment of the present invention, as Figure 3 , Figure 5 , Figure 6 shown, a communication port 53 communicating with the infrared temperature measuring member 3 is opened on the top wall of the sealed space 55, the light-transmitting lens 4 is arranged in the communication port 53, and the water guiding rib 54 surrounds the outer periphery of the communication port 53.

[0053] The steam surging into the sealed space 55 will be liquefied to form condensed water after contacting the side wall of the sealed space 55 and will adhere to the side wall of the sealed space 55. At this time, a part of the liquid flows downward along the side wall of the sealed space 55 under the action of gravity and flows back into the pot, and another part of the liquid gradually flows upward along the side wall of the sealed space 55 under the upward pushing action of the air flow. When the liquid reaches the outer peripheral side of the communication port 53 on the top wall of the sealed space 55, it is blocked by the water guiding rib 54 and cannot reach the communication port 53, but will be guided by the water guiding rib 54 and drip downward from the water guiding rib 54, so that the water guiding rib 54 forms a circle of protection on the outer peripheral side of the light-transmitting lens 4, so that the liquid drips outside the communication port 53 and cannot flow into the light-transmitting lens 4 inside the communication port 53.

[0054] In one embodiment, the water guiding rib 54 surrounds the outer peripheral side of the communication port 53, and the top wall of the sealing space 55 further has a transition section between the water guiding rib 54 and the communication port 53, so that even if part of the liquid crosses the water guiding rib 54 from the outside, it will not directly reach the communication port 53, but will drip under the action of gravity in the transition section.

[0055] In another embodiment, as Figure 5 , Figure 6 shown, the rim of the communication port 53 protrudes downward to form the water guiding rib 54. On the basis of simplifying the structure of the seal 5, the communication port 53 extends downward to form a channel, which can converge the infrared rays irradiated here, so that more infrared rays in the pot can pass through the light-transmitting lens 4 and be sensed by the infrared temperature measuring element 3, reducing the detection error and improving the temperature measurement accuracy.

[0056] As a preferred embodiment of the present utility model, as Figure 3 , Figure 5 , Figure 6 shown, the mounting portion 51 has a mounting channel 511, the light-transmitting lens 4 is arranged inside the mounting channel 511, and the outer peripheral side of the light-transmitting lens 4 cooperates with the mounting channel 511 or the infrared temperature measuring element 3 to form a mounting chamber isolated from the sealing space 55 above the light-transmitting lens 4, and the infrared temperature measuring element 3 is arranged in the mounting chamber.

[0057] In one embodiment, after the light-transmitting lens 4 is installed in the mounting channel 511, the outer peripheral side abuts against the inner wall of the mounting channel 511 to isolate and seal the chambers on the upper and lower sides of the light-transmitting lens 4. The lower chamber is directly communicated with the environment inside the pot, so that the infrared rays inside the pot can irradiate the light-transmitting lens 4. The upper chamber is isolated from the environment inside the pot, thus preventing the gas, liquid and food residues inside the pot from reaching the infrared temperature measuring element 3. Only the infrared rays can pass through the light-transmitting lens 4 and reach the infrared temperature measuring element 3. Thus, the cleanliness of the infrared temperature measuring element 3 is ensured and the detection accuracy is improved.

[0058] In another embodiment, as Figure 3 , Figure 4 , Figure 5 shown, the infrared temperature measuring element 3 has an annular fitting rib 32 extending downward, the light-transmitting lens 4 is located at the lower end of the annular fitting rib 32, and the outer peripheral side abuts against and seals the inner wall of the annular fitting rib 32.

[0059] Preferably, as Figure 3 , Figure 5 shown, the infrared temperature measuring element 3 includes a main body 31 and a detection part. The main body 31 is fixedly connected to the lining cover 1, and the main body 31 and the lining cover 1 clamp and fix the seal 5.

[0060] The clamping and fixing method not only simplifies the installation of the seal 5, but also eliminates the need to process structures such as holes on the seal 5, thereby reducing the processing difficulty of the seal 5 and saving costs.

[0061] Specifically, as Figure 3 shown, the main body 31 is located above the fixing structure of the seal 5, and the lining cover 1 is located below the fixing structure of the seal 5. By firmly connecting the main body 31 and the lining cover 1, a clamping force is formed on the fixing structure by the two, realizing the fixation of the seal 5.

[0062] Furthermore, as Figure 3 、 Figure 5 、 Figure 6 shown, the seal 5 also has a fixing flange 56 located above the installation part 51. The fixing flange 56 is located between the main body 31 and the lining cover 1 so that the main body 31 and the lining cover 1 clamp the fixing flange 56. The fixing flange 56 has a positioning protrusion 561, and the lining cover 1 and / or the main body 31 are provided with a positioning groove 11 that cooperates with the positioning protrusion 561.

[0063] The cooperation between the positioning protrusion 561 and the positioning groove 11 forms a limit. On the one hand, it can play a positioning role in the installation of the seal 5. By the cooperation of the positioning protrusion 561 and the positioning groove 11, the position of the seal 5 is relatively fixed, thereby ensuring the reliability of deformation. On the other hand, it can play a limiting role on the seal 5, preventing the seal 5 from slipping out between the main body 31 and the lining cover 1 when the seal 5 undergoes a large degree of deformation.

[0064] Specifically, as Figure 3 、 Figure 5 shown, the positioning groove 11 is provided on the lining cover 1 and has an upward opening. The positioning protrusion 561 is folded downward and extended. After the two are hooked and cooperated, the main body 31 is pressed above the fixing flange 56 to achieve fixation. Of course, the positioning groove 11 can also be provided on the main body 31, or both the main body 31 and the lining cover 1 are provided with positioning grooves 11, and the positioning protrusion 561 cooperates with the positioning grooves 11 on the upper and lower sides respectively. In a specific example, the main body 31 is a fixing rib that laterally extends from the outside of the infrared temperature measuring part 3. As Figure 6 shown, the fixing flange 56 is also provided with a sealing rib 562 that protrudes upward. The seal 5 is in contact and sealed with the main body 31 to increase the friction force between the two and improve the position stability of the seal 5.

[0065] Furthermore, the main body 31 and the lining cover 1 can be fixed by means such as screws and buckles, which are not limited here.

[0066] As Figure 2 、 Figure 3 shown, the lining cover 1 is also provided with an installation opening for the seal 5 to pass through.

[0067] In a preferred embodiment, asFigure 3 , Figure 7 As shown in Figure 7 , the inner lid 2 is provided with a detection port 21. The lower end of the sealing lip 52 abuts against the inner lid 2 and surrounds the outer periphery of the detection port 21. The detection port 21 and the infrared temperature measuring member 3 are arranged corresponding to each other vertically.

[0068] The sealing lip 52 and the inner lid 2 cooperate to form a sealing space 55, and the detection port 21 communicates with the sealing space 55, so that the infrared rays inside the pot can enter the sealing space 55 through the detection port 21. And the detection port 21 and the infrared temperature measuring member 3 are arranged corresponding to each other vertically, so that the infrared rays entering the sealing space 55 directly irradiate to the light-transmitting lens 4 and are finally sensed by the infrared temperature measuring member 3.

[0069] Specifically, as shown in Figure 6 , the sealing lip 52 has a wrinkled portion, so that it can deform vertically and contract or expand when being squeezed by the inner lid 2 and the liner lid 1, thereby ensuring the contact posture between the lower end of the sealing lip 52 and the inner lid 2 and ensuring the sealing performance. The wrinkled portion protrudes towards the outside of the sealing space 55. Figure 6

[0070] As a preferred embodiment, as shown in Figure 7 , a mating sink 22 is provided on one side of the inner lid 2 facing the liner lid 1. The mating sink 22 corresponds to the infrared temperature measuring member 3. The detection port 21 is located in the mating sink 22. The bottom wall of the mating sink 22 has a sealing plane 221. The lower end of the sealing lip 52 abuts and seals against the sealing plane 221. Figure 7

[0071]

[0072] The mating sink 22 is recessed downward. On the one hand, it can play a role in avoiding the sealing lip 52 of the seal 5, and there is enough space between the inner lid 2 and the liner lid 1 to accommodate the sealing lip 52, so that the sealing lip 52 maintains a good shape and avoids the sealing lip 52 being over-squeezed and affecting the sealing performance. On the other hand, the lower end of the sealing lip 52 abuts and seals against the sealing plane 221 in the mating sink 22. The sealing plane 221 is flatter, abuts more closely against the sealing lip 52, increases the contact area and improves the sealing effect.

[0072] Preferably, an anti-fog layer is provided on the side of the light-transmitting lens 4 facing the inner lid 2.

[0073] The anti-fog layer can further effectively block or weaken the formation of water droplets or water vapor on the surface of the light-transmitting lens 4. Thus, no matter at any stage of cooking, it can ensure the smoothness of the light-transmitting lens 4, thereby ensuring the light-transmitting effect, ensuring the sensitivity and accuracy of the infrared temperature measuring member 3 to receive infrared rays, and ensuring accurate temperature measurement.
