Description

Technical Field

[0001] The utility model relates to the field of kitchen appliances, in particular to a frying and roasting machine. Background Art

[0002] At present, in order to improve the ease of cleaning of the baking tray, the grilling machine industry often makes the baking tray into a detachable structure, which can be removed for cleaning, making it convenient for users to operate. Furthermore, in order to improve the safety of baking tray cleaning, some solutions separate the heating element from the baking tray, that is, the heating element is set in the shell, and after the baking tray is installed, the heat generated by the heating element can be transferred to the baking tray and then the ingredients on the baking tray are grilled. When the heating element is set separately from the baking tray, if the heating element is not installed properly (or there is a processing error in the heating element itself), the heating element may not be in a horizontal state as a whole and may tilt. After the baking tray is installed, the baking tray and the heating element cannot be fully in contact (there is partial non-contact), resulting in poor contact between the heating element and the baking tray, which will affect the heat transfer efficiency of the heating element to the baking tray and thus affect the heating efficiency of the baking tray.

[0003] For example, the existing Chinese patent CN215777494U discloses a grilling machine, in which the heating element is fixed on the reflector. The position of the heating element is fixed, which is not conducive to controlling the parallelism between the grilling pan and the heating element. If the heating element is partially high or partially low, the contact between the heating element and the grilling pan will be poor, which will inevitably affect the heating effect and heating efficiency of the grilling pan.

[0015] The outer surface of the lower baking pan is provided with a plurality of heat-conducting ribs, and the plurality of heat-conducting ribs are arranged radially outward from the center of the lower baking pan.

[0016] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0017] 1. In order to solve the technical problem of low heating efficiency of the baking tray caused by poor fit between the heating element and the baking tray, the grilling machine of the utility model adopts a floating installation for the heating device, that is, the heating device can float up and down to a certain extent under the action of the elastic member, which provides favorable conditions for the heating device to better fit the lower baking tray; when the lower baking tray is installed, the downward pressure provided by the lower baking tray can prompt the compressed elastic member to drive the heating device to fit the lower baking tray, which can optimize the contact effect between the heating device and the lower baking tray, improve the heating efficiency of the lower baking tray, and at the same time avoid the problem that uneven heating of the lower baking tray causes uneven heating of food and affects the taste.

[0018] 2. As a preferred embodiment, the heating device includes a heating tube, the elastic member includes a mounting portion and an elastic member bent upward relative to the mounting portion and suspended in the air, the mounting portion is fixed to the bottom wall of the accommodating cavity, the elastic member is provided with a slot, the heating tube is clamped in the slot, and the elastic member drives the heating tube to float up and down; thus, the elastic member is clamped in the slot to the heating tube and can drive the heating tube to float up and down, the elastic member has a simple structure, which is conducive to simplifying the structural configuration and reducing costs.

[0019] Furthermore, in order to improve the efficiency of installing the lower baking tray in place, in one embodiment, the elastic portion extends from one end of the mounting portion away from the mounting portion, and an obtuse angle is formed between the elastic portion and the mounting portion. Since the elastic portion extends in a direction away from the mounting portion, the elastic portion is easy to deform, so when the lower baking tray is installed, the elastic portion can quickly push the heating device to fit the lower baking tray, thereby improving the installation efficiency.

[0020] Furthermore, in order to improve the supporting effect of the elastic member on the heating pipe and ensure that the heating pipe is stably suspended, in one embodiment, the elastic portion extends from one end of the mounting portion to the other end close to the mounting portion, and an acute angle is formed between the elastic portion and the mounting portion. Since the elastic portion and the mounting portion are mostly overlapped in horizontal projection, the overall structural strength of the elastic member can be strengthened, so that under the premise that the heating pipe can float, the stability and reliability of the elastic portion supporting the heating pipe are improved, and the heating pipe can be prevented from collapsing the elastic portion.

[0021] 3. In order to improve the balance of the elastic member supporting the heating tube as a whole, so that the heating tube floats as a whole and avoids the heating tube partially fitting poorly with the lower baking tray, as a preferred embodiment, the heating tube includes an annular outer ring heating tube and an inner ring heating tube surrounded by the outer ring heating tube, the outer ring heating tube is provided with a plurality of the elastic members along the circumferential direction, and the inner ring heating tube is provided with a plurality of the elastic members along the circumferential direction. That is, according to the shape of the heating tube, by arranging a plurality of elastic members to evenly support the heating tube, it can be ensured that the heating tube as a whole is in contact with the lower baking tray, so that the lower baking tray is heated evenly, thereby improving the uniformity of heating the food. In addition, with this shape of heating tube, the heating tube has a large coverage area, which can ensure that the center and the edge of the lower baking tray can be heated, thereby improving the uniformity of heating the food by the lower baking tray.

[0022] Furthermore, in order to enhance the balance of the inner and outer ring heating tubes supported and avoid the situation where the inner and outer ring heating tubes have inconsistent heights, in one embodiment, the heating tube further includes two connecting sections, and the two ends of the heating section of the outer ring heating tube are respectively connected to the two ends of the heating section of the inner ring heating tube through the two connecting sections, and the elastic member is provided below the connecting section. Among them, the connecting section plays the role of connecting the outer ring heating tube and the inner ring heating tube. By elastically supporting this position, the balance of the support of the inner and outer ring heating tubes can be enhanced to improve the contact effect between the heating tube and the baking tray as a whole; and the two connecting sections are close to each other, and this position concentrates a part of the heat. By enhancing the contact between this position and the baking tray, the utilization rate of this part of the heat can be improved and the heat loss can be reduced.

[0023] 4. In order to simplify the structure of the elastic member and reduce the cost, as a preferred embodiment, the elastic member includes a spring, the lower surface of the heating device abuts against the upper end of the spring, and the heating device floats up and down through the spring. The use of the spring to install the heating device will only cause minor structural changes to the existing grilling machine and will not increase the cost. The spring is a common accessory and is easy to replace when it fails, which is conducive to improving the versatility of the product.

[0024] In order to improve the reliability of the axial movement of the spring and avoid the spring deflection during the movement, which may lead to the failure of the support for the lower baking tray or the difficulty of the spring to reset, in one embodiment, the elastic member also includes a guide column, the lower end of which can be axially movably penetrated through the bottom wall of the accommodating cavity, the spring is sleeved on the outer side of the guide column, the heating device includes a heating tube, the lower surface of which abuts against the upper end of the spring, and the guide column guides the axial movement of the spring. By providing the guide column, the spring can move axially along the guide column, so that the spring will not deviate from its central axis, and at the same time it is conducive to the smooth movement of the spring, so that the spring can smoothly drive the heating tube to be close to the lower baking tray, and avoid impact on the lower baking tray, thereby ensuring the reliability of the installation of the lower baking tray.

[0025] In order to improve the contact effect between the heating tube and the lower grill pan as a whole and make the lower grill pan heated evenly, in one embodiment, the heating device includes a mounting bracket and a heating tube arranged on the mounting bracket, and the mounting bracket is elastically supported by a plurality of springs. As a result, the mounting bracket has good overall floating balance, which can ensure that all parts of the heating tube are in the same horizontal state, thereby ensuring that all parts of the heating tube can fit with the lower grill pan, which is conducive to the lower grill pan being heated evenly and thus improving the uniformity of heating food; the mounting bracket is conducive to increasing the contact area with the spring, which can further improve the stability of the support.

[0026] 5. Usually, the temperature at the center of the baking pan is higher than the temperature at the edge of the baking pan. In order to improve the uniformity of the baking pan heating the food and avoid the food at the edge of the baking pan being insufficiently heated, resulting in a lighter color and a poor taste, as a preferred embodiment, the outer surface of the lower baking pan is provided with a plurality of heat-conducting ribs, which are arranged radially from the center of the lower baking pan to the outside.

[0045] like Figures 1 to 8 As shown, the present application provides a grilling machine, including a lower grilling plate assembly 10, wherein the lower grilling plate assembly 10 includes a lower shell 11, a heating device 12 and a lower grilling plate 13 detachably mounted on the lower shell 11, wherein the lower shell 11 is provided with a receiving cavity 111, wherein an elastic member 14 is disposed in the receiving cavity 111, wherein the heating device 12 is floatably disposed in the receiving cavity 111 through the elastic member 14, and when the lower grilling plate 13 is installed, the lower grilling plate 13 presses down the heating device 12 so that the elastic member 14 is compressed, so that the compressed elastic member 14 drives the heating device 12 to fit the lower grilling plate 13.

[0046] In order to solve the technical problem that the poor fit between the heating element and the baking tray leads to low heating efficiency of the baking tray, the grilling machine of the utility model adopts a floating installation for the heating device 12, that is, the heating device 12 can float up and down to a certain extent under the action of the elastic member 14, which provides favorable conditions for the heating device 12 to better fit the lower baking tray 13; when the lower baking tray 13 is installed, the lower baking tray 13 provides a downward pressure to prompt the compressed elastic member 14 to drive the heating device 12 to fit the lower baking tray 13, which can optimize the contact effect between the heating device 12 and the lower baking tray 13, improve the heating efficiency of the lower baking tray 13, and at the same time avoid the problem that the lower baking tray 13 is heated unevenly, resulting in uneven heating of food and affecting the taste.

[0047] like Figure 3 , Figures 6 to 8 As shown, compared with the conventional fixed arrangement of the heating device 12, the heating device 12 of the present application can float along the axial direction. When the lower baking tray 13 is installed, the lower baking tray 13 will provide a downward pressure to the elastic member 14. After being compressed, the elastic member 14 can cause the heating device 12 to be close to the lower baking tray 13, thereby ensuring better contact between the heating device 12 and the lower baking tray 13. It can be understood that before the lower baking tray 13 is installed, the elastic member 14 is already in a certain deformation state due to the influence of the gravity of the heating device 12 itself. When the lower baking tray 13 is placed, the elastic member 14 is further deformed and can then quickly push the heating device 12 up to fit the lower baking tray 13, thereby ensuring the coordination efficiency between the heating device 12 and the lower baking tray 13.

[0048] The heating device 12 can be a heating tube 121, a heating plate, etc., and one or more elastic members 14 can be used. The deformation amount of the elastic member 14 is sufficient to make the effective heating structure or heating structure of the heating device 12 fit all with the lower baking tray 13 after the lower baking tray 13 is installed, so as to ensure the heating efficiency and uniform heating of the lower baking tray 13.

[0049] As a preferred embodiment, the heating device 12 includes a heating tube 121, and the elastic member 14 includes a mounting portion 141 and an elastic portion 142 that is bent upward relative to the mounting portion 141 and suspended in the air. The mounting portion 141 is fixed to the bottom wall of the accommodating cavity 111, and the elastic portion 142 is provided with a slot 144. The heating tube 121 is snapped into the slot 144, and the elastic portion 142 drives the heating tube 121 to float up and down. Figure 1 or Figure 4 As shown, the mounting portion 141 is provided with a mounting hole 143, which can be connected to the bottom wall by screws, and the elastic portion 142 is used to limit the heating tube 121 and drive the heating tube 121 to float. Figure 2 or Figure 5 As shown, the elastic part 142 is clamped to one end of the heating tube 121, and after the heating tube 121 is subjected to force, it can drive the heating tube 121 to bounce up and down, and finally make the heating tube 121 close to the lower baking tray 13. The elastic part 142 is provided with a U-shaped clamping groove 144 for clamping the heating tube 121, and the structure is simple and reliable to use. Furthermore, in order to prevent the elastic part 142 from floating frequently and causing the connection position of the elastic part 142 and the mounting part 141 to be easily broken, the connection position of the elastic part 142 and the mounting part 141 can be thickened to extend the service life of the elastic member 14.

[0050] Furthermore, in order to improve the efficiency of installing the lower baking tray 13 in place, in one embodiment, the elastic portion 142 extends from one end of the mounting portion 141 away from the mounting portion 141, and an obtuse angle is formed between the elastic portion 142 and the mounting portion 141. Figures 1 to 3 As shown, since the elastic portion 142 extends in a direction away from the mounting portion 141, the elastic portion 142 is easy to deform, so when the lower baking tray 13 is installed, the elastic portion 142 can quickly push the heating device 12 to fit the lower baking tray 13, thereby improving the installation efficiency.

[0051] Furthermore, in order to improve the supporting effect of the elastic member 14 on the heating tube 121 and ensure that the heating tube 121 is stably suspended, in one embodiment, the elastic portion 142 extends from one end of the mounting portion 141 to the other end close to the mounting portion 141, and an acute angle is formed between the elastic portion 142 and the mounting portion 141. Figures 4 to 6 As shown, since the elastic portion 142 and the mounting portion 141 are mostly overlapped in horizontal projection, the overall structural strength of the elastic member 14 can be enhanced, so that under the premise that the heating tube 121 can float, the stability and reliability of the elastic portion 142 supporting the heating tube 121 are improved, and the heating tube 121 can be prevented from collapsing the elastic portion 142.

[0052] It should be noted that the floating of the elastic part 142 ensures that the heating tube 121 is always located above the mounting part 141, that is, the heating tube 121 will not fit the mounting part 141. Preferably, the distance that the elastic part 142 moves downward after being compressed is not greater than half of the initial height of the elastic part 142, so as to ensure the supporting effect of the elastic part 142 on the heating tube 121 and at the same time satisfy the force of providing the heating tube 121 to fit upwardly with the lower baking tray 13. The initial height of the elastic part 142 refers to the height of the elastic part 142 when the lower baking tray 13 is not installed.

[0053] The heating tube 121 of the present application may be a circular heating tube 121, or may be a special-shaped heating tube 121, such as Figure 3 or Figure 6 As shown, the heating tube 121 is provided with more than one circle, which can increase the heating area, so that the heat covers more areas of the lower baking tray 13, and improves the uniformity of heating of the lower baking tray 13.

[0054] In order to improve the balance of the overall support of the heating tube 121 by the elastic member 14, so that the heating tube 121 floats as a whole and avoids the poor fit between the heating tube 121 and the lower baking tray 13, as a preferred embodiment, the heating tube 121 includes an annular outer ring heating tube 122 and an inner ring heating tube 123 surrounded by the outer ring heating tube 122, and the outer ring heating tube 122 is provided with a plurality of the elastic members 14 along the circumferential direction, and the inner ring heating tube 123 is provided with a plurality of the elastic members 14 along the circumferential direction.

[0055] like Figure 3 or Figure 6 As shown, according to the shape of the heating tube 121, by arranging a plurality of elastic members 14 to evenly support the heating tube 121, it can be ensured that the heating tube 121 as a whole is in contact with the lower baking tray 13, so that the lower baking tray 13 is heated evenly, and the uniformity of heating the food is improved. In addition, by adopting the heating tube 121 of this shape, the heating tube 121 has a large coverage area, which can ensure that the center of the lower baking tray 13 and the edge of the lower baking tray 13 can be heated, and the uniformity of heating the food by the lower baking tray 13 can be improved. Among them, the outer ring heating tube 122 and the inner ring heating tube 123 can both be circular or non-circular, and by supporting the outer ring heating tube 122 and the inner ring heating tube 123, the two can be at the same horizontal height, so that the outer ring heating tube 122 and the inner ring heating tube 123 can both be in contact with the lower baking tray 13, avoiding the problem of partial contact failure.

[0056] Furthermore, in order to enhance the balance of the inner and outer ring heating tubes and avoid the situation where the inner and outer ring heating tubes are at different heights, in one embodiment, the heating tube 121 further includes two connecting sections 124, and the two ends of the heating section of the outer ring heating tube 122 are respectively connected to the two ends of the heating section of the inner ring heating tube 123 through the two connecting sections 124, and the elastic member 14 is provided below the connecting section 124. Figure 3 or Figure 6 As shown, the connecting section 124 serves to connect the outer ring heating tube 122 and the inner ring heating tube 123. By elastically supporting this position, the balance of the inner and outer ring heating tubes 122 can be strengthened to improve the contact effect between the heating tube 121 and the baking tray as a whole. In addition, the two connecting sections 124 are close to each other, and this position concentrates a part of the heat. By strengthening the contact between this position and the baking tray, the utilization rate of this part of the heat can be improved and the heat loss can be reduced. The connecting section 124 preferably adopts an arc tube to facilitate smooth transition and increase the heating area.

[0057] In the above solution, the elastic member 14 adopts a sheet-like structure, but the structure of the elastic member 14 is not limited thereto. For example, a common spring 145 can also be used in the present application.

[0058] As a preferred embodiment, the elastic member 14 includes a spring 145, the lower surface of the heating device 12 abuts against the upper end of the spring 145, and the heating device 12 floats up and down through the spring 145. Figure 7 As shown, the heating device 12 is installed by using a spring 145, which makes little structural change to the existing grilling machine and does not increase the cost. In addition, the spring 145 is a common accessory and is easy to replace when it fails, which is beneficial to improving the versatility of the product.

[0059] In order to improve the reliability of the axial movement of the spring 145 and avoid the deflection of the spring 145 during the movement, which may lead to the failure of the support for the lower baking plate 13 or the difficulty in resetting the spring 145, in one embodiment, the elastic member 14 also includes a guide column, the lower end of which can be axially movably penetrated through the bottom wall of the accommodating cavity 111, and the spring 145 is sleeved on the outer side of the guide column. The heating device 12 includes a heating tube 121, the lower surface of the heating tube 121 abuts against the upper end of the spring 145, and the guide column guides the axial movement of the spring 145.

[0060] By providing the guide column, the spring 145 can move axially along the guide column, so that the spring 145 will not deviate from its central axis, and at the same time, it is conducive to the smooth movement of the spring 145, so that the spring 145 can smoothly drive the heating tube 121 to be close to the lower baking tray 13, and avoid impact on the lower baking tray 13, thereby ensuring the reliability of the installation of the lower baking tray 13. Specifically, when installing the lower baking tray 13, the heating tube 121 is compressed to compress the spring 145, and the lower end of the spring 145 is against the bottom wall. Since the lower end of the guide column can move axially, when the upper end of the spring 145 is compressed, the guide column will also move downward accordingly, thereby ensuring that the spring 145 is deformed, which helps the spring 145 to always move axially to avoid eccentricity.

[0061] In the above solution, the elastic member 14 directly contacts and acts on the heating tube 121 . When the heating device 12 is an integral structure, there are other matching modes between the heating device 12 and the elastic member 14 .

[0062] In order to improve the contact effect between the heating tube 121 and the lower grill 13 as a whole and make the lower grill 13 heated evenly, in one embodiment, the heating device 12 includes a mounting bracket 125 and a heating tube 121 disposed on the mounting bracket 125, and the mounting bracket 125 is elastically supported by a plurality of the springs 145. Figure 8 As shown, the mounting bracket 125 floats as a whole and has good balance, which can ensure that all parts of the heating tube 121 are in the same horizontal state, thereby ensuring that all parts of the heating tube 121 can fit the lower grill 13, which is conducive to uniform heating of the lower grill 13 and thus improves the uniformity of heating food; the mounting bracket 125 is conducive to increasing the contact area with the spring 145, which can further improve the stability of the support. In this embodiment, the heating device 12 has a certain weight as a whole, and the reliability of the axial movement of the spring 145 will not be affected when the guide column is omitted.

[0063] Usually, the temperature at the center of the baking tray is higher than the temperature at the edge of the baking tray. In order to improve the uniformity of heating the food by the baking tray and avoid insufficient heating of the food at the edge of the baking tray, resulting in a lighter color and poor taste, as a preferred embodiment, the outer surface of the lower baking tray 13 is provided with a plurality of heat-conducting ribs, and the plurality of heat-conducting ribs are arranged radially from the center of the lower baking tray 13 to the outside.

[0064] The use of heat-conducting ribs can achieve the goal of conducting a portion of the heat near the center of the baking tray to the edge of the baking tray, supplementing the heat at the edge of the baking tray, thereby solving the problem of uneven heating of the baking tray. The heat-conducting ribs can be straight ribs or arc-shaped ribs, which are not limited in this application. The heat-conducting ribs extend from the center of the lower baking tray 13 to the edge of the lower baking tray 13. For heating tubes 121 of different forms, when the heating tubes 121 are working, the heat is preferentially transferred to the corresponding part of the heat-conducting ribs, and then the heat can be transferred to the surrounding baking trays under the conduction of the heat-conducting ribs. Ultimately, the heat distribution on the baking tray can be even, and the food on the baking tray can be evenly heated, thereby improving the overall taste of the food.
