Description

Technical Field

[0001] The utility model discloses a split-type cooking device, belonging to the technical field of cooking devices. Background Art

[0002] With the development and promotion of the small household appliance industry, cooking equipment has become popular among consumers due to its advantages such as easy portability, fast heating and diverse functions. Cooking equipment usually includes a base, a pot body and a reflector cover fixed on the base. The reflector cover is provided with a heating plate. When the pot body is stacked on the base, the bottom of the pot body contacts the heating plate. When the cooking equipment is started, the heating plate generates heat, which in turn heats the pot body to cook the food.

[0003] In order to increase the heating area between the heating plate and the pot body, existing cooking devices usually provide a downwardly open groove at the bottom of the pot body, and the local heating plate protrudes and extends into the groove, so that the heating inside the pot body is more evenly distributed. However, due to processing errors or long-term use, the surface of the heating plate in the protruding part and the inner wall of the groove are deformed due to local heating, which may cause the gap between the groove and the protrusion of the heating plate to become larger. Specifically, the protrusion of the heating plate and the top wall of the groove cannot maintain good contact. When the fit between the heating plate and the pot body is poor, it may cause slow heat conduction and low heating efficiency in a local area between the heating plate and the pot body, and may even cause the thermostat to trip before the pot body reaches the target temperature, resulting in uneven heating and intermittent heating inside the pot body, which makes the heating effect of the cooking device worse. Utility Model Content

[0004] The purpose of the present utility model is to solve the problem in existing cooking equipment that the local raised part of the heating plate and the top wall of the groove are easily unable to fit tightly due to deformation. To this end, a split cooking device is provided, which enables the first heating plate to maintain a tight fit with the top wall of the groove, thereby improving the heat conduction efficiency of the heating plate.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A split cooking device includes a base, a pot body and a reflective cover fixed to the base, the reflective cover is provided with a first heating plate and a second heating plate, the first heating plate is floatingly connected to the reflective cover, the bottom surface of the pot body is provided with a downwardly open groove, the first heating plate extends into the groove and abuts against the top wall of the groove away from the notch, an elastic member is provided between the first heating plate and the reflective cover, the elastic member acts on the first heating plate and makes the first heating plate have a movement tendency away from the reflective cover.

[0007] The beneficial effects of adopting the utility model are:

[0008] In the present invention, the first heating plate and the reflector are floatingly connected by an elastic member, and the elastic member makes the first heating plate have a tendency to move away from the reflector. When the pot body is stacked on the base, part of the first heating plate will extend into the groove, and the gravity of the pot body itself will act on the first heating plate, causing the elastic member to be squeezed. At this time, the elastic force generated by the elastic member will act on the first heating plate and push the first heating plate upward, so that the first heating plate first keeps in contact with the bottom of the pot body and the top wall of the groove. When the first heating plate is pressed down a certain distance, the second heating plate keeps in contact with the bottom of the pot body. At the same time, under the action of the elastic member, the first heating plate has a tendency to move close to the top wall of the groove. Therefore, under the action of the gravity of the pot body and the elastic force of the elastic member, the first heating plate and the top wall of the groove can be kept tightly and securely. The first heating plate is then moved closer to the top wall of the groove, and the gap between the first heating plate and the top wall of the groove is offset by the deformation of the elastic member, thereby greatly reducing the gap between the first heating plate and the top wall of the groove, and even making the first heating plate and the top wall of the groove effectively fit, thereby improving the thermal conductivity of the first heating plate. As a result, the size of the gap between the part of the first heating plate in the groove and the wall of the groove can be guaranteed, thereby ensuring the thermal conductivity between the raised part of the local heating plate of the split cooking device and the pot body, and solving the problem of poor heating effect of the cooking device when the pot body groove or the heating plate is locally deformed.

[0009] Preferably, the first heating plate includes a connecting column, an elastic member is sleeved on the outer peripheral side of the connecting column, the reflector is provided with a through hole, the bottom end of the connecting column is provided with a limiter, the bottom end of the connecting column passes through the through hole and the limiter is against the bottom surface of the reflector. With the above technical solution, the through hole can limit the connecting column, so that the connecting column can slide in the through direction of the through hole, making the sliding of the connecting column smoother; in addition, the first heating plate is provided with a plurality of connecting columns, and through the cooperation of the connecting columns and the through hole, the circumferential deflection of the first heating plate can be limited, making the lifting and lowering of the first heating plate smoother, so that the first heating plate can be closer to the top wall of the groove; secondly, the limiter can limit the rising distance of the connecting column, so as to prevent the connecting column from rising too high and detaching from the through hole, which helps to improve the connection stability between the connecting column and the reflector.

[0010] Preferably, the edge of the through hole is provided with an upwardly extending rib, and the elastic member is sleeved on the outer periphery of the rib. Using the aforementioned technical solution, the rib can position the elastic member, making the abutment between the elastic member and the reflector more stable and reliable, reducing the possibility of the elastic member shifting on the reflector, and ensuring that the elastic member can provide a stable force for the first heating plate. Furthermore, the rib can also increase the range of restriction on the connecting column, thereby reducing the shaking amplitude of the connecting column, reducing the possibility of the connecting column deflecting, and making the raising and lowering of the connecting column more stable and smooth.

[0011] Preferably, the limiting member is a fastener, and a threaded hole is provided at the bottom end of the connecting column. The fastener is threadedly connected to the connecting column through the threaded hole, and the maximum diameter of the fastener is larger than the diameter of the through hole. Using the above technical solution, the fastener is threadedly connected to the connecting column, thereby achieving a detachable connection between the first heating plate and the reflector, and can also reduce the difficulty of connecting the first heating plate and the reflector. It can also facilitate the maintenance and replacement of the first heating plate, thereby helping to reduce the maintenance cost of the cooking equipment.

[0012] Preferably, the first heating plate includes a plug-in end extending into the groove, and there is a gap D between the side wall of the plug-in end and the side wall of the groove, and 0.2mm≤D≤0.5mm. The above-mentioned technical solution can prioritize ensuring that the plug-in end and the top wall of the groove are kept in contact, avoiding interference between the side wall of the plug-in end and the side wall of the groove, which leads to a large gap between the plug-in end and the top wall of the groove, thereby affecting the heat conduction efficiency of the first heating plate, and at the same time, it can also provide a certain amount of deformation space for the plug-in end and the groove, thereby extending the service life of the cooking equipment; and when D is less than 0.2mm, the gap between the side wall of the plug-in end and the side wall of the groove is smaller. When the plug-in end or the groove is deformed, the plug-in end will interfere with the groove to limit the plug-in end from continuing to penetrate into the groove, thereby causing the plug-in end to A large gap is formed between the top of the connecting end and the top wall of the groove, which will also affect the fit between the first heating plate and other parts of the pot body, greatly reducing the heating area of ​​the first heating plate and the pot body, and affecting the heat conduction efficiency of the first heating plate to the pot body; and when D>0.5mm, the gap between the side wall of the plug-in end and the side wall of the groove is too large, and the heat generated by the side wall of the plug-in end cannot be effectively transferred to the side wall of the groove, which can easily lead to a large amount of heat loss, affecting the heat conduction efficiency of the first heating plate to the pot body, and may even cause the thermostat to trip before the pot body reaches the target temperature, resulting in intermittent heating problems.

[0013] Preferably, the bottom wall of the pot body is recessed upward to form the groove at the bottom of the pot body, and a boss is formed within the pot body. A baffle is provided around the top of the boss. The baffle and the boss cooperate to separate the interior space of the pot body into a first cooking cavity and a second cooking cavity, with the first cooking cavity being located on the inner periphery of the baffle and the second cooking cavity being located on the outer periphery of the baffle. Using the aforementioned technical solution, the baffle divides the interior space of the pot body into the first cooking cavity and the second cooking cavity, allowing the pot body to cook two different foods simultaneously, achieving a zoned heating effect, meeting the user's diverse cooking needs, and making the cooking device more flexible and convenient to use.

[0014] Preferably, the diameter of the first heating disk gradually decreases from the bottom to the top of the first heating disk. The above technical solution allows the first heating disk to penetrate the groove more smoothly, ensuring that the top of the first heating disk can preferentially fit with the top wall of the groove, reducing the possibility of the first heating disk and the groove getting stuck, resulting in a large gap between the first heating disk and the top wall of the groove. At the same time, the gap between the side wall of the first heating disk and the side wall of the groove can also be reduced, which helps to improve the thermal conductivity of the first heating disk.

[0015] Preferably, the maximum diameter of the first heating plate is larger than the notch diameter of the recess, and the first heating plate partially abuts the bottom of the second cooking cavity. The aforementioned technical solution enables the first heating plate to contact the bottom surface of the pot body, increasing the heating area between the first heating plate and the pot body and improving the heating efficiency of the first heating plate.

[0016] Preferably, the second heating plate is fixed to the reflective cover, the second heating plate is annular and the first heating plate is located inside the second heating plate, and the second heating plate is against the bottom of the second cooking cavity.

[0017] Preferably, the cooking device further comprises a pot lid and at least one steamer basket. The steamer basket can be stacked on the pot body, and the pot lid can be mounted on either the steamer basket or the pot body. By adopting the aforementioned technical solution, the cooking device equipped with a steamer basket can function as a steamer, thereby increasing the functional versatility of the cooking device and enabling a multi-purpose cooking device. Users only need one cooking device to achieve a variety of different cooking effects, thereby helping to reduce the user's home appliance costs.

In the description of this utility model, "plurality" means two or more, unless expressly limited otherwise.

[0030] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0031] Example 1:

[0032] like Figures 1 to 6 As shown, this embodiment shows a split cooking device, including a base 1 and a pot body 4, the top of the base 1 is open and a reflector 2 is fixedly installed in the base 1, a first heating plate 31 and a second heating plate 32 are provided on the reflector 2, the first heating plate 31 is floatingly connected to the reflector 2, and the second heating plate 32 is fixed to the reflector 2, the pot body 4 is stacked on the base 1 and covers the opening of the base 1, and a downwardly open groove 44 is provided on the bottom surface of the pot body 4. When the pot body 4 is placed on the base 1, the first heating plate 31 partially extends into the groove 44 and abuts against the top wall of the groove 44 away from the notch, and an elastic member 313 is provided between the first heating plate 31 and the reflector 2. The elastic member 313 acts on the first heating plate 31 and makes the first heating plate 31 have a movement tendency away from the reflector 2.

[0033] When the pot body 4 is stacked on the base 1, part of the first heating plate 31 will extend into the groove 44, and the weight of the pot body 4 itself will act on the first heating plate 31, so that the elastic member 313 will be squeezed. At this time, the elastic force generated by the elastic member 313 will act on the first heating plate 31 and push the first heating plate 31 upward, so that the first heating plate 31 will first be in contact with the bottom of the pot body 4 and the top wall of the groove 44. After the first heating plate 31 is pressed down a certain distance, the second heating plate 32 will be in contact with the bottom of the pot body 4. At the same time, under the action of the elastic member 313, the first heating plate 31 has a movement tendency close to the top wall of the groove 44. Therefore, under the action of the gravity of the pot body 4 and the elastic force of the elastic member 313, the first heating plate 31 and the top wall of the groove 44 can be The cam 313 of the second heating element 31 is pressed against the top wall of the first heating element 31 and the bottom wall of the second heating element 31 is pressed against the top wall of the second heating element 31.

[0034] like Figure 4 and Figure 5When the cam 314 is in the closed position, the cam 316 is in the closed position, and the cam 317 is in the open position, so that the cam 316 is in the open position and the cam 317 is in the open position. After the heating plate 31 rises to a certain height, the fastener 314 will abut against the bottom surface of the reflector 2, thereby limiting the further rise of the first heating plate 31; when the pot body 4 is placed on the base 1, the pot body 4 will press down on the first heating plate 31, causing the first heating plate 31 to descend and compress the elastic member 313. When the first heating plate 31 descends a certain distance, the bottom surface of the pot body 4 contacts the second heating plate 32. At this time, the force of the elastic member 313 on the second heating plate 32 increases, thereby increasing the thrust on the first heating plate 31, so that the first heating plate 31 can maintain a close fit with the top wall of the groove 44; in addition, when the first heating plate 31 or the inner wall of the groove 44 is deformed, under the action of the elastic member 313, the first heating plate 31 can also be brought closer to the top wall of the groove 44, reducing the distance between the first heating plate 31 and the top wall of the groove 44, or even keeping the first heating plate 31 in contact with the top wall of the groove 44, so as to improve the heat conduction efficiency of the first heating plate 31.

[0035] In addition, when the pot body 4 is stacked on the base 1 or detached from the base 1, the first heating plate 31 will rise or fall under the action of the pot body 4 and the elastic member 313, and the through hole 21 can limit the connecting column 312 so that the connecting column 312 can slide in the penetrating direction of the through hole 21, making the sliding of the connecting column 312 smoother; in addition, the first heating plate 31 is provided with a plurality of connecting columns 312, and the cooperation of the connecting columns 312 and the through hole 21 can limit the circumferential deflection of the first heating plate 31, making the lifting and lowering of the first heating plate 31 smoother, so that the first heating plate 31 can be closer to the groove 4 4; secondly, the fastener 314 forms an abutment fit with the bottom surface of the reflector 2, thereby limiting the rising distance of the connecting column 312; the through hole 21 can limit the connecting column 312, so that the connecting column 312 can keep sliding in the penetrating direction of the through hole 21, so that the sliding of the connecting column 312 is smoother; in addition, the first heating disk 31 is provided with a plurality of connecting columns 312, and the cooperation of the connecting columns 312 and the through hole 21 can limit the circumferential deflection of the first heating disk 31, so that the lifting and lowering of the first heating disk 31 is smoother, so that the first heating disk 31 can be closer to the top wall of the groove 44.

[0036] In order to further reduce the swing amplitude of the connecting column 312, the edge of the through hole 21 in this embodiment is provided with an upwardly extending rib, which can increase the restriction range of the connecting column 312, thereby reducing the swing amplitude of the connecting column 312, reducing the possibility of the connecting column 312 being deflected, and making the lifting and lowering of the connecting column 312 more stable and smooth; in addition, the end of the elastic member 313 that abuts against the reflector 2 is sleeved on the outer peripheral side of the rib, and the rib can position the elastic member 313, so that the abutment between the elastic member 313 and the reflector 2 is more stable and reliable, reducing the possibility of the elastic member 313 being positionally offset on the reflector 2, and ensuring that the elastic member 313 can provide a stable force for the first heating plate 31.

[0037] Of course, it is understandable that in other embodiments, the ribs may be formed by extending the edge of the through hole 21 downward, that is, the ribs are provided on the bottom surface of the reflector 2; or, the ribs may be formed by extending the edge of the through hole 21 upward and downward at the same time, that is, the ribs may be provided on both the upper surface and the bottom surface of the reflector 2.

[0038] like Figure 2 and Figure 3As shown, in this embodiment, the first heating plate 31 includes a plug-in end 311 that penetrates into the groove 44. When the top of the plug-in end 311 is against the top wall of the groove 44, the first heating plate 31 is connected to the pot body 4. At this time, there is a gap D between the side wall of the plug-in end 311 and the side wall of the groove 44, and 0.2mm≤D≤0.5mm. This design can prioritize ensuring that the plug-in end 311 and the top wall of the groove 44 remain in contact, avoiding interference between the side wall of the plug-in end 311 and the side wall of the groove 44, resulting in a larger gap between the plug-in end 311 and the top wall of the groove 44, thereby affecting the heat conduction efficiency of the first heating plate 31, and at the same time providing a certain amount of deformation space for the plug-in end 311 and the groove 44, thereby extending the service life of the cooking device; and when D < 0.2mm, the gap between the side wall of the plug-in end 311 and the side wall of the groove 44 The gap between the plug end 311 and the groove 44 is too large, and the heat generated by the side wall of the plug end 311 cannot be effectively transferred to the side wall of the groove 44, which can easily lead to a large amount of heat loss, affecting the thermal conductivity of the first heating plate 31 to the pot body 4, and may even cause the pot body 4 to trip before the thermostat reaches the target temperature, resulting in intermittent heating.

[0039] In addition, in order to make the connection between the plug end 311 and the groove 44 smoother, in this embodiment, the diameter of the first heating disk 31 gradually decreases from the bottom end to the top end of the first heating disk 31, and the width of the corresponding groove 44 gradually decreases from the notch to the top wall. When the top end of the plug end 311 just extends into the groove 44, the distance between the side wall of the plug end 311 and the side wall of the groove 44 is large. As the plug end 311 continues to extend, the distance between the side wall of the plug end 311 and the side wall of the groove 44 gradually decreases. In this process, the distance between the first heating disk 31 and the groove 44 can be reduced. The possibility of the groove 44 getting stuck and forming a large gap between the first heating disk 31 and the top wall of the groove 44 makes it smoother for the first heating disk 31 to penetrate into the groove 44, ensuring that the top of the first heating disk 31 can be kept in contact with the top wall of the groove 44 first; in addition, after the plug-in end 311 and the groove 44 are completely plugged in, the gap between the side wall of the first heating disk 31 and the side wall of the groove 44 can be kept uniform, thereby reducing the gap between the side wall of the first heating disk 31 and the side wall of the groove 44, which helps to improve the thermal conductivity efficiency of the first heating disk 31.

[0040] like Figure 2As shown, in this embodiment, the maximum diameter of the first heating disk 31 is larger than the notch diameter of the groove 44, that is, the diameter of the lowest end of the first heating disk 31 is larger than the notch diameter of the groove 44. When the plug-in end 311 is connected with the groove 44, the part of the first heating disk 31 close to the lowest point is against the bottom of the second cooking cavity 42, which can increase the heating area between the first heating disk 31 and the pot body 4 and improve the heating efficiency of the first heating disk 31.

[0041] like Figure 2 、 Figure 3 and Figure 6 As shown, the groove 44 in this embodiment is arranged at the central part of the bottom surface of the pot body 4. The groove 44 is formed by the bottom wall of the pot body 4 being recessed upward. The recessed part extends into the interior of the pot body 4 and forms a boss 45 inside the pot body 4. The edge of the top of the boss 45 is surrounded by a baffle 43. The top surface of the baffle 43 is close to the opening of the pot body 4 but does not protrude from the opening of the pot body 4. The baffle 43 and the boss 45 cooperate to divide the internal space of the pot body 4 into a first cooking cavity 41 and a second cooking cavity 42. The first cooking cavity 41 is located on the inner peripheral side of the baffle 43, and the second cooking cavity 42 is located on the outer peripheral side of the baffle 43. When the pot body 4 is stacked on the base 1, the top of the plug-in end 311 in the first heating plate 31 is lower than the lower side of the first cooking cavity 41, directly providing heat to the first cooking cavity 41. The side wall of the plug-in end 311 in the heating plate 31 is close to the side wall of the groove 44, thereby conducting heat to the side wall of the boss 45 to heat the second cooking cavity 42. In addition, the second heating plate 32 is against the bottom of the second cooking cavity 42, directly providing heat to the second cooking cavity 42. The cooperation of the first heating plate 31 and the second heating plate 32 can enable the second cooking cavity 42 to achieve three-dimensional heating, greatly increase the heating area of ​​the second cooking cavity 42, and improve the cooking efficiency of the second cooking cavity 42; in addition, the internal space of the pot body 4 is divided into the first cooking cavity 41 and the second cooking cavity 42 by the baffle 43, so that the pot body 4 can cook two different foods at the same time, achieving the effect of zoned heating, which can meet the user's various cooking needs and make the use of the cooking equipment more flexible and convenient.

[0042] like Figure 1 and Figure 2 As shown, the cooking device in this embodiment also includes a pot cover 51 and at least one steamer 5. The steamer 5 can be stacked on the pot body 4, and the pot cover 51 can be covered on the steamer 5 or the pot body 4. The cooking device is equipped with a steamer 5, which can make the cooking device have the function of a steamer, improve the functional diversity of the cooking device, so that the cooking device can achieve a multi-purpose effect of one machine. The user only needs one cooking device to achieve a variety of different cooking effects, which helps to reduce the user's home appliance costs.
