Description

Technical Field

[0001] The present application relates to the technical field of cooking appliances, and particularly to a griddle. Background Art

[0002] A griddle, also known as an electric griddle, includes a base assembly and an upper cover assembly. The upper cover assembly can rotate relative to the base assembly, so that the griddle can cook with the cover closed or with the cover open. During the process of cooking food with the cover closed, due to continuous high-temperature heating, the food is likely to become dry, thus affecting the taste. For this reason, some griddles that can generate steam to supplement moisture to the food have emerged on the market. These griddles are mainly of two types. One type is to set an independent steam generator in the upper cover assembly, and generate steam leading to the cooking cavity through the steam generator, so as to supplement moisture to the food at any time. However, this type of griddle often has a complex structure and high cost. The other type is to set a water tank on the lower baking tray, and the water in the water tank evaporates when the lower baking tray is heated, so as to generate steam to supplement moisture to the food. However, this type of griddle needs to add enough water to the water tank before cooking, and cannot add water with the cover open during cooking (adding water with the cover open during cooking will cause steam to escape and the temperature to drop rapidly, affecting the cooking effect). On the one hand, it is necessary to heat all the water in the water tank to boiling to generate steam, and the steam generation time is long; on the other hand, when the water in the water tank dries up, steam cannot be generated continuously, and the use is very inconvenient. Summary of the Utility Model

[0003] Based on this, it is necessary to provide a griddle that can generate steam quickly and can add water during the cooking process.

[0004] A griddle includes a base assembly, an upper cover assembly and a water tank assembly. The upper cover assembly can be closed on the base assembly. The base assembly includes a lower baking tray, and the lower baking tray is provided with a cooking groove and a water tank. The water tank assembly is installed on the base assembly or the upper cover assembly. The water tank assembly includes a box body and a pipeline. The box body can be communicated with the water tank through the pipeline, and a switch valve is arranged on the pipeline. The switch valve is used to control the on-off of the pipeline.

[0005] For the griddle provided by the present application, it is not necessary to fill the water tank with water before cooking. Only need to add water to the box body. When the water tank needs water, open the switch valve to make the pipeline communicate the box body and the water tank, so that the water in the box body can flow into the water tank. When enough water is added, close the switch valve to make the box body and the water tank not communicate, thus stopping the water addition. Moreover, the amount of water flowing into the water tank can be controlled by the switch valve. When in use, only a small amount of water can be added to the water tank, so that steam can be generated quickly when heating the water tank. And during the cooking process, only by controlling the opening and closing of the switch valve can the addition or stop of water from the box body to the water tank be controlled, without opening the upper cover assembly, thus avoiding the problem that the steam escapes and the temperature drops rapidly due to adding water with the cover open, which affects the cooking effect.

[0006] In one embodiment, the water tank assembly is mounted on the upper cover assembly, the upper cover assembly includes an upper baking tray, the upper baking tray has a water injection port, one end of the pipeline communicates with the water injection port, and when the upper cover assembly is closed on the base assembly, the orthographic projection of the water injection port on the base assembly falls into the water tank.

[0007] In this way, the water tank assembly is mounted on the upper cover assembly. When the upper cover assembly is closed on the base assembly, the box body is located above the lower baking tray, so that the water in the box body can flow into the water tank of the lower baking tray by its own gravity, without setting up a mechanism such as a water pump to provide power for the water supply, and the structure is simpler. Since when the upper cover assembly is closed on the base assembly, the orthographic projection of the water injection port on the base assembly falls into the water tank, when the upper cover assembly is closed on the base assembly and the switch valve is opened, the water in the box body flows through the pipeline to the water injection port and directly flows into the water tank through the water injection port, and the structure is very simple.

[0008] In one embodiment, the upper cover assembly includes an upper shell and an upper baking tray, the box body has a water filling port, the water tank assembly is mounted between the upper shell and the upper baking tray, and at least the water filling port is exposed from the upper shell.

[0009] In this way, the water tank assembly is mounted between the upper shell and the upper baking tray, the structure is very compact, and at least the water filling port is exposed from the upper shell, which is convenient to add water into the box body through the water filling port.

[0010] In one embodiment, the switch valve includes a valve body and a valve core. The valve body has a valve cavity and a water inlet and a water outlet communicating with the valve cavity. The pipeline includes a first pipe connected to the water inlet and a second pipe connected to the water outlet. The first pipe communicates with the box body, the second pipe communicates with the water tank, the valve core is movably arranged in the valve cavity, the valve core has an open position and a closed position. When the valve core moves to the open position, the water inlet communicates with the water outlet; when the valve core moves to the closed position, the water inlet and the water outlet are cut off.

[0011] In this way, by controlling the movement of the valve core, the opening and closing of the switch valve can be controlled, so as to control the on-off of the water flow. The switch valve has a simple structure and is easy to control.

[0012] In one embodiment, the switch valve further includes a first elastic member. The valve core is movably arranged in the valve cavity along its axial direction, and the first elastic member applies a force to the valve core to make the valve core move towards the closed position.

[0013] In this way, when the valve core is in the closed position, the first elastic member can firmly hold the valve core in the closed position, preventing water leakage due to the loose closing of the on-off valve. When it is necessary to open the on-off valve, only by applying a force to the valve core to overcome the elastic force of the first elastic member can the valve core be moved to the open position, thereby opening the on-off valve.

[0014] In one embodiment, the on-off valve further includes a valve cover. The valve cavity has an opening, and the valve cover is sealingly connected to the opening. One end of the valve core penetrates through the valve cover and extends from the side of the valve cover away from the valve body.

[0015] In this way, the opening of the valve cavity is provided to facilitate the installation of the valve core in the valve cavity. By providing the valve cover and sealingly connecting the valve cover to the opening, water leakage at the opening of the valve cavity can be avoided. One end of the valve core extends from the side of the valve cover away from the valve body, so that the movement of the valve core can be controlled from the outside of the valve body.

[0016] In one embodiment, the end of the valve cavity away from the valve cover is provided as a conical groove. Both the water inlet and the water outlet are provided on the side wall of the conical groove. The end of the valve core away from the valve cover is provided with a sealing portion. The outer wall of the sealing portion is provided as a conical surface adapted to the conical groove. When the valve core moves to the open position, the outer wall of the sealing portion does not contact the side wall of the conical groove; when the valve core moves to the closed position, the outer wall of the sealing portion abuts against the side wall of the conical groove.

[0017] In this embodiment, by providing the conical groove and setting the sealing portion of the valve core as a conical surface, the outer wall of the sealing portion can closely adhere to the inner wall of the conical groove when the on-off valve is closed, forming a good block. And when it is necessary to open the on-off valve, the sealing portion can easily come out of the conical groove, so that the opening and closing actions of the on-off valve can be easily controlled.

[0018] In one embodiment, a stepped surface is provided on the outer wall of the valve core. The first elastic member is sleeved outside the valve core, and both ends of the first elastic member respectively abut against the stepped surface and the valve cover.

[0019] In this way, the structure is compact, and the valve core plays a limiting role on the first elastic member, ensuring that the first elastic member will not fall off, thereby ensuring that the first elastic member applies a force to the valve core to move towards the closed position.

[0020] In one embodiment, a manual switch assembly is further provided on the upper cover assembly. The manual switch assembly includes a button, a second elastic member, and a pressing lock. The button is connected to one end of the valve core extending out of the valve cover to control the movement of the valve core. The pressing lock is used to cooperate with the button to lock the button when the button is pressed in the first direction and release the button when the button is pressed in the first direction again. When the pressing lock locks the button, the elastic force of the first elastic member causes the valve core to be in the closed position. The second elastic member exerts a force on the button in a direction opposite to the first direction to enable the button to automatically reset when the pressing lock is released and drive the valve core to move toward the open position.

[0021] In this way, by providing the manual switch assembly, the manual control of the on-off valve can be realized, so that the user can control the opening and closing of the on-off valve at any time according to needs during use, which is very convenient. The manual switch assembly provided in this embodiment can switch the opening and closing state of the on-off valve by pressing the button, and has a simple structure and very convenient operation.

[0022] In one embodiment, the button includes a pressing portion and a push rod provided on one side of the pressing portion. A locking portion is provided at the end of the push rod. The pressing lock is provided with a buckle, and the buckle is used to cooperate with the locking portion to lock or release the button by the pressing lock.

[0023] The button provided in this embodiment is provided with a push rod, so that the locking portion and the pressing portion are spaced apart by a certain distance, which is convenient for the buckle of the pressing lock to lock the locking portion. The structure of the button is very simple and easy to process.

[0024] In one embodiment, a connecting rod is provided on one side of the push rod. The valve core is provided with a mating hole. The connecting rod passes through the mating hole, and the connecting rod can move in the mating hole so that when the valve core is in the closed position, the button can move relative to the valve core and press the pressing lock in the first direction.

[0025] Since the valve core cannot continue to move in the direction away from the open position when it is in the closed position, the above setting in this embodiment enables the button to still move in the first direction when the valve core is in the closed position, so as to press the pressing lock, so that the buckle of the pressing lock releases the locking portion, and thus the valve core can move to the open position under the elastic force of the second elastic member, ensuring the switching of the opening and closing state of the on-off valve by pressing the button.

[0026] In one embodiment, the upper cover assembly includes an upper shell and an upper baking tray. The upper shell is provided with a receiving groove, and the button is installed in the receiving groove. The button further includes a guiding column connected to the pressing portion. The bottom wall of the receiving groove is provided with a first hole and a second hole. The pressing lock is installed in the first hole, the guiding column passes through the second hole, the second elastic member is sleeved outside the guiding column, and two ends of the second elastic member respectively abut against the pressing portion and the bottom wall of the receiving groove.

[0027] In this way, the first hole provides an installation position for the pressing lock, and the second hole and the guiding column play a role in limiting the second elastic member to prevent the second elastic member from falling off, so as to ensure that the second elastic member provides an elastic force to the pressing portion.

[0028] In one embodiment, the base assembly further includes a bottom shell and a lower heating member. The lower heating member is disposed between the bottom shell and the lower baking tray. The lower heating member includes a first heating member and a second heating member. The first heating member is used to heat the cooking groove, and the second heating member is used to heat the water tank.

[0029] In this way, the first heating member and the second heating member can be independently controlled, so that steam can be independently provided, avoiding the dry burning state of the water tank when steam is not needed, making the use more convenient, and being beneficial to extending the service life of the griddle.

The term "and / or" used in the specification of the present application includes any and all combinations of one or more of the related listed items.

[0050] Please refer to Figures 1 to 4, this application provides a griddle, which includes a base assembly 10, an upper cover assembly 20 and a water tank assembly 30. The upper cover assembly 20 can be covered on the base assembly 10. In this application, the upper cover assembly 20 is rotatably connected to the base assembly 10 through a hinge assembly. During cooking, the upper cover assembly 20 can be opened for lid-open cooking, or the upper cover assembly 20 can be covered on the base assembly 10 for lid-closed cooking.

[0051] The base assembly 10 includes a lower baking tray 12, and the lower baking tray 12 is provided with a cooking groove 121 and a water tank 122. The water tank assembly 30 is installed on the base assembly 10 or the upper cover assembly 20. The water tank assembly 30 includes a box body 31 and a pipeline 32. The box body 31 can be communicated with the water tank 122 through the pipeline 32, and a switching valve 40 is arranged on the pipeline 32. The switching valve 40 is used to control the on-off of the pipeline 32. For the griddle provided by this application, it is not necessary to fill the water tank 122 with water before cooking. Only need to add water to the box body 31. When the water tank 122 needs water, open the switching valve 40 to make the pipeline 32 communicate the box body 31 and the water tank 122, then the water in the box body 31 can flow into the water tank 122. When enough water is added, close the switching valve 40 to make the box body 31 and the water tank 122 not communicate, thus stopping the water supply. Moreover, the amount of water flowing into the water tank 122 can be controlled by the switching valve 40. When in use, only a small amount of water can be added to the water tank 122, so that steam can be quickly generated when heating the water tank 122. And during the cooking process, only by controlling the opening and closing of the switching valve 40 can the water addition from the box body 31 to the water tank 122 be controlled or the water addition be stopped, without opening the upper cover assembly 20, thus avoiding the problems of steam escaping and the temperature dropping rapidly due to opening the lid to add water, which affect the cooking effect.

[0052] Further, please refer to Figures 1 to 3 , the water tank assembly 30 is installed on the upper cover assembly 20. In this way, when the upper cover assembly 20 is covered on the base assembly 10, the box body 31 is located above the lower baking tray 12, so that the water in the box body 31 can flow into the water tank 122 of the lower baking tray 12 by its own gravity, without setting a mechanism such as a water pump to provide power for the water supply, and the structure is simpler. Of course, in other embodiments, the water tank assembly can also be installed on the base assembly, as long as the water in the box body can be transported to the water tank through the pipeline. The box body can be set at a position higher than the water tank or at a position lower than the water tank. If the water in the box body cannot flow into the water tank by its own gravity, a water pump can be set to provide power for the water flow transportation.

[0053] Please refer to Figure 1 and Figure 3, In one embodiment, the upper cover assembly 20 includes an upper shell 21 and an upper baking tray 22. The box body 31 has a water filling port 311. The water tank assembly 30 is installed between the upper shell 21 and the upper baking tray 22, and at least the water filling port 311 is exposed outside the upper shell 21. In this way, the water tank assembly 30 is installed between the upper shell 21 and the upper baking tray 22, and the structure is very compact. At least the water filling port 311 is exposed outside the upper shell 21, which is convenient for adding water into the box body 31 through the water filling port 311. It can be understood that "exposed outside" means being exposed outside, that is, not being blocked. It does not specifically refer to the water filling port 311 protruding from the upper shell 21. The water filling port 311 can protrude from the upper shell 21, can also be recessed below the upper shell 21, or the end face of the water filling port 311 is flush with the outer wall of the upper shell 21. As long as the water filling port 311 is exposed outside the upper shell 21 and water can be added into the box body 31 through the water filling port 311.

[0054] In this embodiment, the box body 31 is integrally formed with the upper shell 21, but it is not limited thereto. In other embodiments, the box body 31 can also be an independent component independent of the upper shell 21, as long as the box body 31 is connected to the upper shell 21.

[0055] As Figure 1 shown, the water tank assembly 30 further includes a box cover 33, and the box cover 33 covers the water filling port 311. In this way, foreign objects can be prevented from falling into the box body 31. Further, a first sealing ring 34 is provided between the box cover 33 and the box body 31. The setting of the first sealing ring 34 can form a sealed connection between the box cover 33 and the box body 31, thereby avoiding water leakage, and thus the upper cover assembly 20 can be turned over and opened. The first sealing ring 34 is a silica gel sealing ring with good sealing effect.

[0056] Further, please refer to Figure 3 and Figure 4 , the upper baking tray 22 has a water injection port 221, and one end of the pipeline 32 is communicated with the water injection port 221. When the upper cover assembly 20 is covered on the base assembly 10, the orthographic projection of the water injection port 221 on the base assembly 10 falls into the water tank 122. In this way, when the upper cover assembly 20 is covered on the base assembly 10 and the switch valve 40 is opened, the water in the box body 31 flows through the pipeline 32 to the water injection port 221 and directly flows into the water tank 122 through the water injection port 221, and the structure is very simple.

[0057] Please refer to Figure 3 , Figure 5 and Figure 6, the upper cover assembly 20 further includes an upper heating element 23 and an upper reflector 24. The upper heating element 23 is installed on the back of the upper baking tray 22 and is used to heat the upper baking tray 22. In this embodiment, the upper heating element 23 is a heating tube, which has a simple structure. The upper reflector 24 is arranged between the upper shell 21 and the upper baking tray 22. The upper heating element 23 is installed on the upper reflector 24 and is located on the side of the upper reflector 24 facing the upper baking tray 22. The box body 31 is arranged between the upper reflector 24 and the upper shell 21. In this way, the upper reflector 24 reflects the heat dissipated by the upper heating element 23 towards the upper shell 21 to the upper baking tray 22, improving the heating efficiency. The upper reflector 24 also plays a role in heat insulation, which can prevent the upper shell 21 from having too high a temperature rise and can prevent the water in the box body 31 from being heated to generate steam.

[0058] Please refer to Figures 7 to 9 , the switching valve 40 includes a valve body 41 and a valve core 42. The valve body 41 has a valve cavity 411 and a water inlet 412 and a water outlet 413 communicating with the valve cavity 411. The pipeline 32 includes a first pipe 321 connected to the water inlet 412 and a second pipe 322 connected to the water outlet 413. The first pipe 321 communicates with the box body 31, and the second pipe 322 communicates with the water tank 122. The valve core 42 is movably arranged in the valve cavity 411. The valve core 42 has an open position and a closed position. When the valve core 42 moves to the open position, the water inlet 412 communicates with the water outlet 413; when the valve core 42 moves to the closed position, the water inlet 412 and the water outlet 413 are blocked. In this way, by controlling the movement of the valve core 42, the opening and closing of the switching valve 40 can be controlled, thereby controlling the on-off of the water flow. The switching valve 40 has a simple structure and is easy to control.

[0059] In one embodiment, the first pipe 321 and the second pipe 322 are made of flexible hoses. In this way, it is convenient to adjust the installation positions of the first pipe 321 and the second pipe 322 in the upper shell 21, making the installation of the pipeline 32 more flexible.

[0060] In this embodiment, the switching valve 40 is arranged between the upper reflector 24 and the upper shell 21. The first pipe 321 is arranged between the upper reflector 24 and the upper shell 21. The second pipe 322 passes through the upper reflector 24 and is connected to the water injection port 221. Please refer to Figure 3 and Figure 6 as shown.

[0061] Please refer to Figures 7 to 9, In one embodiment, the switching valve 40 further includes a first elastic member 43. The valve core 42 is movably disposed in the valve cavity 411 along its axial direction, and the first elastic member 43 applies a force to the valve core 42 to move the valve core 42 toward the closed position. In this way, the first elastic member 43 enables the valve core 42 to be stably held in the closed position when in the closed position, avoiding water leakage due to the insecure closing of the switching valve 40. When the switching valve 40 needs to be opened, only the force acting on the valve core 42 needs to overcome the elastic force of the first elastic member 43, so that the valve core 42 can be moved to the open position, thereby opening the switching valve 40.

[0062] Further, the switching valve 40 further includes a valve cover 44. The valve cavity 411 has an opening, and the valve cover 44 is sealingly connected to the opening. One end of the valve core 42 passes through the valve cover 44 and extends from the side of the valve cover 44 away from the valve body 41. In this way, the valve cavity 411 is provided with an opening, which is convenient for installing the valve core 42 in the valve cavity 411. By providing the valve cover 44 and the valve cover 44 being sealingly connected to the opening, water leakage at the opening of the valve cavity 411 can be avoided. One end of the valve core 42 extends from the side of the valve cover 44 away from the valve body 41, so that the operation of the valve core 42 can be controlled from the outside of the valve body 41.

[0063] A second sealing ring 45 can be provided between the valve cover 44 and the valve body 41 to seal the connection between the valve cover 44 and the valve body 41 and avoid water leakage at the connection. The second sealing ring 45 can be a silicone sealing ring, which has a good sealing effect.

[0064] In this embodiment, a cover hole 441 is provided on the valve cover 44, and one end of the valve core 42 passes through the cover hole 441. In order to prevent water in the valve cavity 411 from leaking out through the cover hole 441, a third sealing ring (not shown) can be provided between the valve core 42 and the valve cover 44, or a third sealing ring (not shown) can be provided between the valve core 42 and the valve body 41.

[0065] Please refer to Figure 7 and Figure 8 , one end of the valve cavity 411 away from the valve cover 44 is provided as a conical groove 4111, the water inlet 412 and the water outlet 413 are both provided on the side wall of the conical groove 4111, and one end of the valve core 42 away from the valve cover 44 is provided with a sealing portion 421, and the outer wall of the sealing portion 421 is provided as a conical surface adapted to the conical groove 4111. As Figure 7 shown, when the valve core 42 moves to the open position, the outer wall of the sealing portion 421 does not contact the side wall of the conical groove 4111, so that water can pass through the gap between the outer wall of the sealing portion 421 and the inner wall of the conical groove 4111, and the water inlet 412 and the water outlet 413 are communicated; as Figure 8As shown, when the valve core 42 moves to the closed position, the outer wall of the sealing portion 421 abuts against the side wall of the conical groove 4111, so that the sealing portion 421 blocks the water inlet 412 and the water outlet 413, and the water inlet 412 and the water outlet 413 are separated. In this embodiment, by providing the conical groove 4111 and setting the sealing portion 421 of the valve core 42 as a conical surface, when the switch valve 40 is closed, the outer wall of the sealing portion 421 can closely adhere to the inner wall of the conical groove 4111 to form a good block. And when the switch valve 40 needs to be opened, the sealing portion 421 can easily escape from the conical groove 4111, so that the opening and closing actions of the switch valve 40 can be easily controlled.

[0066] As Figure 7 and Figure 8 shown, one end of the water inlet 412 connecting to the valve cavity 411 is provided as a small hole, that is, the inner diameter of one end of the water inlet 412 connecting to the valve cavity 411 is smaller than the inner diameters of other parts. Similarly, one end of the water outlet 413 connecting to the valve cavity 411 is provided as a small hole. In this way, the valve core 42 of the switch valve 40 can easily block the water inlet 412 and the water outlet 413, avoiding the problem that it is difficult to close the switch valve 40 due to excessive water flow.

[0067] Please refer to Figure 8 , when the valve core 42 is in the closed position, the end face of the sealing portion 421 does not contact the bottom wall of the conical groove 4111. In this way, it can be avoided that due to manufacturing errors, there is a gap between the outer wall of the sealing portion 421 and the side wall of the conical groove 4111 when the valve core 42 is in the closed position, resulting in the switch valve 40 not being tightly closed.

[0068] Further, please refer to Figures 7 to 9 , a stepped surface 422 is provided on the outer wall of the valve core 42. The first elastic member 43 is sleeved outside the valve core 42, and both ends of the first elastic member 43 respectively abut against the stepped surface 422 and the valve cover 44. In this way, the structure is compact, and the valve core 42 plays a limiting role on the first elastic member 43 to ensure that the first elastic member 43 will not fall off, thereby ensuring that the first elastic member 43 applies a force to move the valve core 42 toward the closed position. In this embodiment, the first elastic member 43 is a compression spring, which can provide a better elastic force.

[0069] Please refer to Figure 5 and Figure 10 , a manual switch assembly 50 is further provided on the upper cover assembly 20. The manual switch assembly 50 includes a button 51, a second elastic member 52, and a pressing lock 53. The button 51 is connected to one end of the valve core 42 extending out of the valve cover 44 to control the movement of the valve core 42. The pressing lock 53 is used to cooperate with the button 51 to lock the button 51 when the button 51 is pressed in the first direction, as Figure 11 shown, and release the button 51 when the button 51 is pressed in the first direction again, as Figure 12As shown; when the locking button 53 presses the locking button 51, the elastic force of the first elastic member 43 causes the valve core 42 to be in the closed position, as Figure 8 shown. The second elastic member 52 applies a force to the button 51 in the direction opposite to the first direction, so that the button 51 automatically resets when the locking button 53 is released and drives the valve core 42 to move towards the open position. In this way, by setting the manual switch assembly 50, the manual control of the switching valve 40 can be realized, so that the user can control the opening and closing of the switching valve 40 at any time according to needs during use, which is very convenient. It can be understood that the first direction refers to the direction in which the button 51 moves when it is pressed. In this embodiment, the button 51 is arranged on the top surface of the upper shell 21, and the button 51 moves downward when it is pressed. Therefore, the first direction is the downward direction. In other embodiments, if the button is arranged on the side wall of the upper shell, the button moves towards the inside of the upper shell when it is pressed, and the first direction is the direction from the outside of the upper shell to the inside. The following takes "the button 51 is arranged on the top surface of the upper shell 21, and the closed position of the valve core 42 is below the open position" as an example for description. Please refer to Figures 7 to 12 , when the switching valve 40 is in the open state, the user presses the button 51, and the button 51 can push the valve core 42 to move downward, so that the valve core 42 can move to the closed position, making the switching valve 40 switch to the closed state. At this time, the locking button 53 locks the button 51; then, the user presses the button 51 again, and the locking button 53 releases the lock on the button 51, that is, releases the button 51. Then, under the elastic force of the second elastic member 52, the button 51 moves upward and automatically returns to its original position. At the same time, the button 51 drives the valve core 42 to move upward to the open position, and the switching valve 40 switches to the open state. At this time, the stepped surface 422 of the valve core 42 compresses the first elastic member 43. It can be understood that the elastic force of the second elastic member 52 is greater than the elastic force of the first elastic member 43 to ensure that when the locking button 53 releases the button 51, the second elastic member 52 can push up the button 51 and make the valve core 42 compress the first elastic member 43. The manual switch assembly 50 provided in this embodiment can switch the opening and closing states of the switching valve 40 by pressing the button 51, with a simple structure and very convenient operation.

[0070] Please refer to Figure 1 , in this embodiment, the button 51 is arranged on one side of the box body 31. In this way, the appearance is beautiful and it is convenient for the user to use. Further, the upper shell 21 is provided with a receiving groove 211, and the button 51 is installed in the receiving groove 211.

[0071] As Figure 10As shown, the button 51 includes a pressing portion 511 and a push rod 512 provided on one side of the pressing portion 511. A locking portion 513 is provided at the end of the push rod 512. The pressing lock 53 is provided with a buckle 531, and the buckle 531 is used to cooperate with the locking portion 513 to lock or release the button 51 by the pressing lock 53. It is worth mentioning that the pressing lock 53 is a lock with self-locking and spring-opening functions. The buckle 531 is a component of the pressing lock 53 for locking the object to be locked (i.e., the locking portion 513). Pressing the center of the buckle 531 by the locking portion 513 can cause the buckle 531 to close and lock the locking portion 513. Pressing the center of the buckle 531 again by the locking portion 513 can cause the buckle 531 to open, thereby releasing the locking of the locking portion 513. The specific structure and operating principle of the pressing lock 53 are prior art and will not be elaborated here. The button 51 provided in this embodiment, by setting the push rod 512, makes the locking portion 513 and the pressing portion 511 spaced apart by a certain distance, so as to facilitate the buckle 531 of the pressing lock 53 to lock the locking portion 513. The structure of this button 51 is very simple and easy to process. In this embodiment, the locking portion 513 is a conical protrusion provided at the end of the push rod 512, and the pressing lock 53 is provided below the button 51. The locking portion 513 can press the buckle 531 when moving downward. However, it is not limited thereto. In other embodiments, the pressing lock can also be provided on one side of the button. For example, a cross bar can be provided on one side of the push rod, and a locking portion can be provided on the cross bar. As long as the locking portion is provided above the buckle of the pressing lock, when pressing the pressing portion of the button downward, the locking portion can also press the buckle, thereby realizing the locking or unlocking of the locking portion by the buckle.

[0072] Further, a connecting rod 514 is provided on one side of the push rod 512. The valve core 42 is provided with a mating hole 423. The connecting rod 514 passes through the mating hole 423, and the connecting rod 514 can move within the mating hole 423 so that when the valve core 42 is in the closed position, the button 51 can move relative to the valve core 42 and press the pressing lock 53 in the first direction. Since the valve core 42 cannot continue to move in the direction away from the open position (i.e., cannot continue to move downward) when it is in the closed position, this embodiment makes the button 51 still able to move in the first direction (i.e., move downward) when the valve core 42 is in the closed position through the above setting, so as to press the pressing lock 53, making the buckle 531 of the pressing lock 53 release the locking portion 513, so that the valve core 42 can move to the open position under the elastic force of the second elastic member 52, ensuring that the opening and closing state of the switching valve 40 can be switched by pressing the button 51.

[0073] In this embodiment, the mating hole 423 is elongated and extends along the moving direction of the button 51, so that the connecting rod 514 can move between the two ends of the mating hole 423. Specifically, when the switch valve 40 is in the open state, the connecting rod 514 abuts against the upper end of the mating hole 423. At this time, when the button 51 is pressed, the connecting rod 514 moves toward the lower end of the mating hole 423. When the pressing lock 53 is pressed to release the locking portion 513 and the user releases the pressing portion 511 of the button 51, under the elastic force of the second elastic member 52, the button 51 moves upward, so that the connecting rod 514 moves toward the upper end of the mating hole 423. When the connecting rod 514 moves to abut against the upper end of the mating hole 423, the connecting rod 514 can drive the valve core 42 to move upward continuously, so that the valve core 42 moves to the open position and the switch valve 40 is opened.

[0074] As Figure 10 shown, one end of the valve core 42 extending out of the valve cover 44 is bent into an L shape toward the push rod 512. In this way, the mating hole 423 can be arranged close to the push rod 512, so that it is easier to drive the valve core 42 to move upward when the button 51 rises.

[0075] Further, please refer to Figure 11 and Figure 12 , the button 51 further includes a guide post 515 connected to the pressing portion 511. The bottom wall of the receiving groove 211 is provided with a first hole 2111 and a second hole 2112. The pressing lock 53 is installed in the first hole 2111, the guide post 515 passes through the second hole 2112, the second elastic member 52 is sleeved outside the guide post 515, and the two ends of the second elastic member 52 respectively abut against the pressing portion 511 and the bottom wall of the receiving groove 211. In this way, the first hole 2111 provides an installation position for the pressing lock 53, and the second hole 2112 and the guide post 515 play a role in limiting the second elastic member 52 to prevent the second elastic member 52 from falling off, so as to ensure that the second elastic member 52 provides an elastic force for the pressing portion 511.

[0076] In this embodiment, the guide post 515, the second elastic member 52 and the second hole 2112 are all provided in two. The two guide posts 515 are respectively arranged on both sides of the push rod 512. The two second holes 2112 are arranged corresponding to the two guide posts 515. The two second elastic members 52 are respectively sleeved on the two guide posts 515 one by one. In this way, the structure is balanced in force and it is ensured that the button 51 will not be displaced.

[0077] In this embodiment, the second elastic member 52 is a compression spring, which has a simple structure and can provide better elastic force.

[0078] In the above embodiment of the present application, the switch valve 40 is opened and closed by the movement of the valve core 42, but not limited thereto. In other embodiments, the switch valve may also have other different opening and closing methods, as long as the movement of the valve core can control the on-off of the water flow in the pipeline.

[0079] Please refer to Figure 1 and Figure 13 , the base assembly 10 further includes a bottom case 11 and a lower heating element 13. The lower heating element 13 is disposed between the bottom case 11 and the lower baking tray 12. The lower heating element 13 includes a first heating element 131 and a second heating element 132. The first heating element 131 is used to heat the cooking groove 121, and the second heating element 132 is used to heat the water tank 122. In this way, by actively heating the water tank 122 with the second heating element 132, compared with heating the cooking groove with a heating element and transferring heat to the water tank through the cooking groove, steam can be generated faster in this embodiment. It is worth mentioning that the first heating element and the second heating element can be set to be controlled to open and close simultaneously, or can be set to be independently controlled to open and close. For the scheme of independent control of opening and closing, cooking food and providing steam do not interfere with each other, thus avoiding the dry burning state of the water tank 122 when steam is not needed, making it more convenient to use and conducive to extending the service life of the griddle.

[0080] Both the first heating element 131 and the second heating element 132 are heating tubes, with simple structures and low costs. The first heating element 131 is disposed below the cooking groove 121, and the second heating element 132 is disposed below the water tank 122.

[0081] In this embodiment, the water tank 122 is disposed on one side of the cooking groove 121 and is close to the hinge assembly of the griddle, with a very simple structure. In this embodiment, the second heating element 132 is set in an arc shape, with a longer length in a limited space, which is conducive to quickly heating the water tank 122 to generate steam. However, this is not limited thereto. In other embodiments, the second heating element 132 can also be set in a straight line shape.

[0082] In addition, in other embodiments, the lower heating element can also be set as one component, and the lower heating element is simultaneously located below the cooking groove and the water tank, so that the lower heating element can simultaneously heat the cooking groove and the water tank. In this way, the structure is simpler.

[0083] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope described in this specification.

[0084] The above-described embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
