Description

Technical Field

[0001] The present invention relates to the technical field of electric grills, and more particularly to a portable multi-functional electric grill. Background Art

[0002] In the modern fast-paced and dynamic lifestyle, people's pursuit of outdoor dining experiences is increasing day by day. As a powerful tool for outdoor cooking, the importance of portable electric grills is becoming more and more prominent. In outdoor activity scenarios, the power supply has become a key limiting factor. Due to the lack of stable mains power access outdoors, portable electric grills mainly rely on external batteries for power supply.

[0003] Existing electric grills usually have only one heating surface, and the heat dissipates upward, resulting in a large amount of wasted heat energy. The heat generated by the first heating element during operation is not efficiently utilized, and a large amount of heat is dissipated into the surrounding environment senselessly. This not only prolongs the food baking time but also quickly consumes the battery power. Moreover, during storage, since the heat of the grill cannot dissipate in a short time, it is easy to get burned when carrying, posing a safety hazard.

[0004] Based on the above situation, we propose a portable multi-functional electric grill to solve the above problems. Summary of the Invention

[0005] The present invention provides a portable multi-functional electric grill to solve the problems existing in the prior art.

[0006] The technical problems solved by the present invention are achieved by the following technical solutions: A portable multi-functional electric grill includes a connecting member and a heat-insulating water tank. The connecting member includes a horizontal connecting portion and two vertical connecting portions that are slidably connected below the horizontal connecting portion and are oppositely arranged. The horizontal connecting portion is provided with a receiving seat for placing the main grill, and the horizontal connecting portion is provided with a first heating element. A placement rack for placing the sub-grill is slidably connected in a receiving cavity opened in the vertical connecting portion, and the main grill is slidably connected inside the receiving cavity. When the placement rack is pulled out from the vertical connecting portion, the first heating element is located between the main grill and the sub-grill. The heat-insulating water tank is provided on the outer edge of the horizontal connecting portion for temperature isolation of the main grill. A water storage cavity communicating with the receiving cavity is opened in the vertical connecting portion, and the heat-insulating water tank and the water storage cavity are connected by a water delivery hose. A valve is provided on the water delivery hose. When the valve is opened, the cooling water in the heat-insulating water tank can enter the receiving cavity through the water storage cavity to cool the placed main grill and sub-grill.

[0007] Preferably, an overflow pipe is connected to the heat-insulating water tank, and the output end of the overflow pipe is connected to a portion of the water delivery hose downstream of the valve.

[0008] Preferably, a guiding slide rail perpendicular to the pulling direction of the placing rack is further provided on the placing rack, and the auxiliary baking tray is slidably connected to the placing rack through the guiding slide rail.

[0009] Preferably, a fixing member is provided at one end of the placing rack located in the receiving cavity. When the placing rack is pulled out from the receiving cavity, the placing rack is connected to the vertical connecting portion through the fixing member.

[0010] Preferably, a sealing door is provided at one end of the placing rack located outside the receiving cavity, and the sealing door is a longitudinally telescopic structure. A sealing gasket is provided on the inner wall of the sealing door. When the two vertical connecting portions are attached to each other, an extrusion force is generated on the two sealing doors, and the sealing of the receiving cavity is achieved through the sealing gasket.

[0011] Preferably, a limiting member is threadedly connected to the transverse connecting portion. When the limiting member rotates to abut against the outer wall of the vertical connecting portion, the vertical connecting portion is positioned.

[0012] Preferably, a cover plate is hinged to the transverse connecting portion, and a second heating element corresponding to the main baking tray is provided on the inner wall of the cover plate.

[0013] Preferably, a drain pipe for draining water is provided on the receiving cavity.

[0014] The beneficial effects of the present invention are as follows: By arranging the main baking tray and the auxiliary baking tray at the upper and lower ends of the first heating element, heat can be transferred simultaneously upward and downward, reducing the situation of heat dissipation to the surrounding environment, greatly improving the heat utilization rate, and different foods can be cooked on different baking trays to meet diverse cooking needs; The edge of the main baking tray located above is cooled and thermally insulated through the heat-insulating water tank to form a heat-insulating barrier, reducing the risk of scalding. And when the cooling water enters the receiving cavity, the main baking tray and the auxiliary baking tray that are used for baking and stored in the receiving cavity can be cooled again, which is convenient for carrying.

Detailed implementation manners

[0018] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below with reference to specific illustrations.

[0019] Refer to Figures 1-8As shown in the figure, a portable multi-functional electric baking pan includes a connecting member 1. The connecting member 1 includes a horizontal connecting portion 11 and two vertical connecting portions 12 that are dampingly slidably connected below the horizontal connecting portion 11 and are oppositely arranged. A receiving seat 201 is provided on the horizontal connecting portion 11, and a main baking pan 2 is installed on the receiving seat 201. Moreover, the number of main baking pans 2 provided on the horizontal connecting portion 11 can be multiple to meet different cooking requirements. Preferably, it can be set to two to correspond to the number of secondary baking pans 3 described below. And a first heating element 13 is provided below the position corresponding to the horizontal connecting portion 11 and the receiving seat 201. The first heating element 13 can be connected to an external portable battery or in-vehicle power supply through a wire to realize power supply. And an adjustment switch is also provided on the horizontal connecting portion 11. By rotating the adjustment switch, the resistance value connected to the circuit is changed, thereby changing the current, and realizing the adjustment of the heat of the first heating element 13, so as to change the heat of each main baking pan 2. A receiving cavity 102 is formed in the vertical connecting portion 12, and a placement rack 101 for placing the secondary baking pan 3 is slidably connected in the receiving cavity 102. When the placement rack 101 is pulled out from the vertical connecting portion 12, the first heating element 13 is located between the main baking pan 2 and the secondary baking pan 3. At this time, the heat below the first heating element 13 can heat the food on the secondary baking pan 3, which can make full use of the heat, reduce the situation of heat dissipation to the surrounding environment, and improve the energy utilization rate. And because the secondary baking pan 3 is relatively far from the position of the first heating element compared with the main baking pan 2, the heat transfer effect is relatively poor. Therefore, some foods with low heat requirements, such as vegetables, or ingredients that need to be kept warm can be heated on the secondary baking pan 3. And the main baking pan 2 can be slidably connected inside the receiving cavity 102, such as Figure 6 As shown in the figure, when storing, the main baking pan 2 can be removed from the receiving seat, then slid into the receiving cavity 102, and then the placement rack 101 is pushed into the receiving cavity 102, and the two vertical connecting portions 12 move relative to each other to realize storage.

[0020] When baking food, since the main baking tray 2 is directly exposed on the outside, the edge part may have a relatively high temperature due to heat transfer. Accidental contact during baking can cause burns. Therefore, a water-insulating tank 4 for temperature isolation of the main baking tray 2 is provided along the outer edge of the horizontal connecting part 11. A water storage cavity 103 communicating with the loading cavity 102 is formed on the vertical connecting part 12. The water-insulating tank 4 and the water storage cavity 103 are connected by a water delivery hose 104, and a valve 105 is provided on the water delivery hose 104. Before use, cold water can be added to the water-insulating tank 4 in advance to isolate the heat of the main baking tray 2. When the use is completed and it is put away, the valve 105 on the water delivery hose 104 is opened, and the pre-injected cooling water in the water-insulating tank 4 flows into the water storage cavity 103 through the water delivery hose 104. As the water level in the water storage cavity 103 rises, the water slowly flows into the loading cavity 102 through the holes communicating with the loading cavity 102. The water flow diffuses in the loading cavity 102 to absorb the remaining heat of the main baking tray 2 and the auxiliary baking tray 3, realizing cooling and temperature reduction. Moreover, since the heat of the main baking tray 2 is relatively higher than that of the auxiliary baking tray 3, it can be arranged below the auxiliary baking tray 3. The cooling water entering the loading cavity 102 can first exist at the bottom of the loading cavity 102 to first submerge and cool the main baking tray 2. Even when it is put away after baking, the main baking tray 2 and the auxiliary baking tray 3 with un-dissipated heat can be cooled by the cooling water in the loading cavity 102 to avoid burns during carrying.

[0021] Refer to Figure 4 As shown, further, in order to avoid waste caused by overflow when adding a large amount of cooling water to the water-insulating tank 4, an overflow pipe 5 is also connected to the water-insulating tank 4. The output end of the overflow pipe 5 is connected to the part of the water delivery hose 104 downstream of the valve 105. The water exceeding the input end of the overflow pipe 5 can enter the temporary storage cavity and the loading cavity 102 through the overflow pipe 5, and the connecting through hole between the temporary storage cavity and the loading cavity 102 can be misaligned with the auxiliary baking tray 3 to prevent cooling water from dripping on the auxiliary baking tray 3 when the auxiliary baking tray 3 is in the loading cavity 102 and not in use.

[0022] Refer to Figure 3 As shown, further, a guiding slide rail 6 perpendicular to the pulling direction of the placement rack 101 is also provided on the placement rack 101. The auxiliary baking tray 3 is slidably connected to the placement rack 101 through the guiding slide rail 6. The auxiliary baking tray 3 slides along the length extension direction of the horizontal connecting part 11, while the auxiliary baking tray 3 slides along the width direction of the horizontal connecting part 11. When the placement rack 101 drives the auxiliary baking tray 3 to be located below the first heating element 13 for baking, in order to facilitate turning the food on the auxiliary baking tray 3 or taking the food, the auxiliary baking tray 3 can be pulled out from the placement rack 101 to be misaligned with the first heating element 13 for easy operation.

[0023] Refer to Figure 6As shown in the figure, further, one end of the placement rack 101 located inside the receiving cavity 102 is provided with a fixing member 7. The fixing member 7 can be a magnetic tile that can adsorb to the vertical connecting portion 12, or a clamping protrusion that can be snapped into the inside of the vertical connecting portion 12. When the two placement racks 101 are pulled out, one end of the placement rack 101 located inside the receiving cavity 102 is provided with the fixing member 7. When the placement rack 101 is pulled out from the receiving cavity 102, the placement rack 101 is connected to the vertical connecting portion 12 through the fixing member 7, preventing the random sliding of the placement rack 101 from affecting the heating effect of the first heating element 13 on the auxiliary baking tray 3.

[0024] Refer to Figures 6-7 As shown in the figure, further, one end of the placement rack 101 located outside the receiving cavity 102 is provided with a blocking door 8, and the blocking door 8 is a longitudinally telescopic structure, that is, it is composed of at least two blocking plate bodies that can slide and sleeve with each other. When the main baking tray 2 needs to be installed in the receiving cavity 102, the length of the blocking door 8 can be reduced to facilitate the insertion of the main baking tray 2 into the receiving cavity 102. And a sealing gasket 81 is provided on the inner wall of the blocking door 8. The sealing gasket 81 can be made of elastic materials such as rubber and silica gel. When the vertical connecting portions 12 face each other, an extrusion force is generated on the two blocking doors 8, and the blocking door 8 compresses the sealing gasket 81, causing the sealing gasket 81 to deform, so that the sealing effect between the blocking door 8 and the vertical connecting portion 12 is better, reducing the leakage phenomenon when there is cooling water in the receiving cavity 102.

[0025] Among them, a limiting member 9 is threadedly connected to the transverse connecting portion 11. When the limiting member 9 rotates to abut against the outer wall of the vertical connecting portion 12, the vertical connecting portion 12 is positioned, that is, the two vertical connecting portions 12 are clamped by the limiting members 9 on both sides of the transverse connecting portion 11, thus preventing the two vertical connecting portions 12 from separating from each other, facilitating carrying, and the two blocking doors 8 will also be pressed against each other to prevent the main baking tray 2 and the auxiliary baking tray 3 located inside the receiving cavity 102 from sliding out.

[0026] Refer to Figure 1 And Figure 4As shown, further, a cover plate 111 is hinged on the horizontal connecting portion 11. A second heating element 112 corresponding to the main baking tray 2 is provided on the inner wall of the cover plate 111. The size of the cover plate 111 is precisely customized according to the size of the main baking tray 2 to ensure that it can completely cover the main baking tray 2 when closed, forming a good sealing environment. The second heating element 112 can be the same as the first heating element 13, and its shape and size are precisely matched with the heated area of the main baking tray 2, capable of evenly providing heat to the surface of the main baking tray 2. In terms of electrical connection, the power cord of the second heating element 112 can be led out from the edge of the cover plate 111 and connected to the main power line of the electric baking pan through a hidden junction box. The junction box is designed to be waterproof and dustproof, and is equipped with overload protection and short-circuit protection devices inside to ensure electrical safety. Users can conveniently control the on and off of the second heating element 112 through an adjustment switch and flexibly adjust the heating power according to different cooking requirements. When the cover plate 111 is placed on the horizontal connecting portion 11 to form an upper and lower simultaneous heating mode with the heating device under the main baking tray 2, the cooking efficiency can be significantly improved, and the food can be heated more evenly. Even if the second heating element 112 is not turned on, by fitting the cover plate 111 on the horizontal connecting portion 11, it can not only play a certain heat preservation role for the main baking tray 2, but also prevent dust and sundries from falling into the main baking tray 2, keeping the main baking tray 2 clean and hygienic.

[0027] Among them, a drain pipe 121 for draining water is provided on the receiving cavity 102, and a cap 122 is provided at the output end of the drain pipe 121. When the cap 122 is opened, the cooling water in the receiving cavity 102 can be discharged from the receiving cavity 102, reducing the overall mass of the device and making it more convenient to carry.
