Description

Technical Field

[0001] This utility model relates to the field of electric grill technology, specifically a heat dissipation device for an electric grill. Background Technology

[0002] During the use of an electric grill, the ion needle is a key component, and its working condition directly affects the performance and stability of the electric grill. When an electric grill is working, electricity is converted into fire. The discharge temperature of the ion head reaches as high as 1200 degrees Celsius. The temperature of the ion head can easily be conducted to the high-voltage capacitor and potting compound of the grill head through the ion needles, causing the high-voltage capacitor and potting compound to malfunction due to the high temperature. To address this, an air duct is added between the ion needles and the high-voltage capacitor of the grill head, and a fan is used to attenuate the heat conducted by the ion needles, ensuring that the temperature reaching the high-voltage capacitor of the grill head is lower than the 85 degrees Celsius required by the capacitor. Traditional cooling fans use circular axial fans, but the grill head area is large, and a circular axial fan can only blow air locally into the grill head air duct. Another option is to use a crossflow fan, whose blade width can be designed according to the width of the grill head air duct, which can ensure that the entire air duct of the grill head is blown by the fan, achieving good heat dissipation. However, the operating environment of an electric grill is relatively complex. During the grilling process, food residue, oil stains, and dust and other impurities in the air can easily enter the cooling air duct with the airflow. If impurities accumulate on the ion needles, they will affect the discharge effect, leading to unstable ignition or abnormal flame. Utility Model Content

Detailed Implementation

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, in the following description, specific details such as particular system structures and technologies are set forth for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art should understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details hindering the description of the present invention.

[0015] This utility model provides a heat dissipation device for an electric grill, as detailed in the attached instruction manual. Figure 1 To be continued Figure 3 It is known that a heat dissipation device for an electric grill mainly includes the following parts or components: shell 10, air inlet pipe 12, and filter assembly 20.

[0016] In this utility model, a crossflow fan 11 is fixedly installed inside the housing 10. The crossflow fan 11 is used to blow air onto the ion needles inside the electric grill. The air inlet pipe 12 is installed inside the housing 10. Its first end is connected to the air inlet (not shown in the figure) of the crossflow fan 11 through the first quick-release assembly 30, and its second end is connected to the air inlet (not shown in the figure) on the housing 10 through the second quick-release assembly (not shown in the figure). The filter assembly 20 is installed at the air inlet and is used to filter impurities entering the air inlet pipe 12. Specifically, the filter assembly 20 includes a filter plate 21 installed at the air inlet on the outside of the housing 10, and a fixing assembly connected to the filter plate 21 for fixing the filter plate 21.

[0017] When the electric grill is turned on, the crossflow fan 11 starts operating. At this time, outside air enters through the air inlet on the housing 10. Because a filter assembly 20 is installed at the air inlet, the air passes through the filter plate 21 before entering the air inlet duct 12. The filter plate 21 can effectively intercept food residue, oil stains, dust and other impurities in the air. Only the filtered clean air can pass through the filter plate 21 and enter the air inlet duct 12. The filtered air is then transported to the crossflow fan 11 through the air inlet duct 12. The first end of the air inlet duct 12 is tightly connected to the air inlet of the crossflow fan 11 through the first quick-release assembly 30, and the second end is connected to the air inlet on the housing 10 through the second quick-release assembly. This quick-release design ensures smooth air delivery and also provides convenience for subsequent maintenance and cleaning. The crossflow fan 11 blows the drawn-in clean air directly onto the ion needle inside the electric grill. The ion needles generate high temperatures during operation. The airflow from the cross-flow fan 11 effectively removes the heat around the ion needles, dissipating it and preventing overheating from affecting their discharge performance. This ensures the ignition stability and normal flame of the electric grill. After the electric grill has been used for a period of time, a certain amount of impurities will accumulate on the filter plate 21. To ensure the filtration effect, the filter plate 21 needs to be cleaned or replaced regularly. Loosen the fixing components, remove the filter plate 21, rinse it with clean water to remove surface impurities, and after the filter plate 21 is dry, reinstall it at the air inlet or replace it with a new one and install it directly at the air inlet, securing it firmly with the fixing components.

[0018] The filter assembly 20 installed at the air inlet of this device can effectively intercept these impurities. The filter plate 21, as the core part of the filter assembly 20, is located at the air inlet on the outside of the housing 10. It performs preliminary filtration on the air entering the air inlet pipe 12, blocking larger particles. Through filtration, the ion needle can always maintain a clean working state, ensuring its stable discharge performance, guaranteeing the ignition reliability and flame stability of the electric grill, and providing users with better cooking results.

[0019] As one embodiment, in conjunction with the appendix to the specification Figure 2 It is understood that the fixing component includes a support plate 22, which is fixedly mounted on the housing 10 below the air inlet and is adapted to the lower end of the filter plate 21; the pressure plate 23 is slidably mounted on the housing 10 above the air inlet and is adapted to the upper end of the filter plate 21. The pressure plate 23 is pressed against or disengaged from the upper end of the filter plate 21 under the drive of the driving component. The driving component includes a first screw 24, which is vertically mounted on the outside of the housing 10. Its lower end is connected to the upper end of the pressure plate 23 via a rotating shaft. The upper end of the first screw 24 is threadedly connected to and passes through the support plate 25 on the housing 10.

[0020] During installation, when preparing to install the filter plate 21 on the heat dissipation device of the electric grill, first move the filter plate 21 to the air inlet position. The operator places the filter plate 21 on the support plate 22, ensuring that the lower end of the filter plate 21 is fully embedded in the support plate 22, so that the filter plate 21 is in a vertical and stable state, preparing for the subsequent fixing operation. The operator rotates the first screw 24 in one direction. Since the first screw 24 is threadedly connected to the support plate 25, during the rotation, the first screw 24 will move downward along the thread. As the first screw 24 moves downward, through the connection of the rotating shaft, the pressure plate 23 will be subjected to downward pressure, gradually pressing against the upper end of the filter plate 21, ensuring that the filter plate 21 will not shake or shift during operation.

[0021] It is known that the filter plate 21 is on the outside of the housing 10, which is the outer shell of the electric grill. The length of the support plate 22 is greater than the diameter of the air inlet. The air inlet is on the housing 10 and coaxial with the air inlet pipe 12. The air inlet pipe 12 is placed horizontally. When the filter plate 21 is installed on the outside of the housing 10, the side of the filter plate 21 that is close to the housing 10 is in close contact with the outside of the housing 10. The middle part will completely block the air inlet on the housing 10, so that when the air enters, it must be filtered by the filter plate 21. All structures in the filter assembly 20, including the filter plate 21, the pressure plate 23, and the drive assembly, are on the outside of the housing.

[0022] Specifically, the upper end of the tray 22 and the lower end of the pressure plate 23 both have grooves for fitting the filter plate 21, and the side of the groove closest to the housing is borderless. The groove is also larger than the diameter of the air inlet.

[0023] When the filter plate 21 needs cleaning, maintenance, or replacement, the operator rotates the first screw 24 in the opposite direction. Due to the threaded connection, the first screw 24 will move upward along the thread. As the first screw 24 moves upward, the downward pressure on the pressure plate 23 gradually decreases through the shaft connection until the pressure plate 23 is completely detached from the upper end of the filter plate 21. Once the pressure plate 23 is completely detached from the filter plate 21, the operator can remove the filter plate 21.

[0024] Specifically, a rotating wheel 241 is fixedly mounted on the upper end of the first screw 24, which allows for easy rotation of the first screw 24.

[0025] As one embodiment, in conjunction with the appendix to the specification Figure 3 It is known that the first quick-release assembly 30 includes a connecting pipe 31, which is located between the crossflow fan 11 and the first end of the air inlet pipe 12 inside the housing 10. Its first end is fixed at the air inlet of the crossflow fan 11 and connected to the air inlet. The second end of the connecting pipe 31 is a cone 32, and multiple through grooves 33 are provided on the cone 32. The fixing sleeve 34 is sleeved on the connecting pipe 31 and threadedly connected to the connecting pipe 31. The inner cavity 35 of the fixing sleeve 34 is adapted to the cone 32.

[0026] If the air intake duct 12 itself is damaged, aged, or deformed, and a new air intake duct 12 needs to be replaced, disassembly is essential. After disassembling the air intake duct 12, the damaged parts can be easily removed and a new air intake duct 12 can be installed to ensure the normal operation of the heat dissipation system.

[0027] During installation, open the upper part of the housing 10 and insert the first end of the air inlet pipe 12 into the second end (the conical part 32) of the connecting pipe 31. During insertion, the through groove 33 allows the conical part 32 to have a certain elastic deformation capability. When it encounters resistance from the inner wall of the air inlet pipe 12, the conical part 32 can slightly contract, thus entering the interior of the air inlet pipe 12 more smoothly. Then, start rotating the fixing sleeve 34. Since the fixing sleeve 34 and the connecting pipe 31 are threaded, as it rotates in one direction, the fixing sleeve 34 will gradually move away from the air inlet pipe 12 along the connecting pipe 31. During the rotation, the inner cavity 35 of the fixing sleeve 34 will gradually squeeze the conical part 32 of the connecting pipe 31, making the conical part 32 fit more tightly against the air inlet pipe 12, thus achieving a firm connection between the connecting pipe 31 and the air inlet pipe 12. Continue rotating the fixing sleeve 34 until the rotational resistance increases significantly, indicating that the fixing sleeve 34 has firmly fixed the connecting pipe 31 and the air inlet pipe 12 together. At this point, the installation is complete.

[0028] During disassembly, rotate the retaining sleeve 34 in the opposite direction. Due to the threaded connection, the retaining sleeve 34 will gradually move along the connecting pipe 31 towards the air inlet pipe 12. During rotation, the squeezing force of the retaining sleeve 34 on the tapered 32 of the connecting pipe 31 gradually decreases, allowing the end of the tapered 32 to regain some elasticity and reducing the fit between it and the inner wall of the air inlet pipe 12. When the retaining sleeve 34 is rotated to a certain position and the rotational resistance is significantly reduced, it indicates that the retaining sleeve 34 has been basically loosened. At this point, the air inlet pipe 12 can be gently pulled outwards.

[0029] Specifically, the first quick-release component 30 has the same structure as the second quick-release component.

[0030] First, the upper part of the housing 10 will be opened. After opening the upper part of the housing 10, the first quick-release assembly 30, the air inlet pipe 12, and the second quick-release assembly inside the housing 10 will be exposed. When removing the air inlet pipe 12, first move the fixing sleeve 34 of the first quick-release assembly 30 to the left to loosen the cone 32 of the connecting pipe 31. After the cone 32 has no resistance to the connecting pipe 31, gently pull the first end of the air inlet pipe 12 out of the first quick-release assembly 30 to the left. At this time, the hose will contract, so that the rigid tube of the first end of the air inlet pipe 12 will be separated from the connecting pipe 31 on the right side. After the first end is separated, the first end of the air inlet pipe 12 can be picked up. Since the middle of the air inlet pipe 12 is a hose, it will not affect the axial pulling out of the second end of the air inlet pipe 12. Then, pull out the second end of the air inlet pipe 12 axially in a similar way. Using this method, the air inlet pipe 12 can be easily removed.

[0031] The hose is a flexible corrugated tube.

[0032] When disassembling or installing the second end of the air inlet pipe 12, the same method can be used to install or remove the second end of the air inlet pipe 12, except that the first end of the connecting pipe in the second quick-release assembly is connected to the housing 10 and connected to the air inlet.

[0033] Specifically, the two ends of the air inlet duct 12 are rigid pipes, and the middle is a flexible pipe.

[0034] This utility model provides a heat dissipation device for an electric grill. The specific operation process during use is as follows: When the electric grill is turned on, the crossflow fan 11 starts operating. At this time, outside air enters through the air inlet on the housing 10. Because a filter assembly 20 is installed at the air inlet, the air passes through the filter plate 21 before entering the air inlet duct 12. The filter plate 21 can effectively intercept food residue, oil stains, dust and other impurities in the air. Only the filtered clean air can pass through the filter plate 21 and enter the air inlet duct 12. The filtered air is then transported to the crossflow fan 11 through the air inlet duct 12. The first end of the air inlet duct 12 is tightly connected to the air inlet of the crossflow fan 11 through the first quick-release assembly 30, and the second end is connected to the air inlet on the housing 10 through the second quick-release assembly. This quick-release design ensures smooth air delivery and also provides convenience for subsequent maintenance and cleaning. The crossflow fan 11 accelerates the intake of clean air and blows it out, forming a strong airflow that blows directly towards the ion needles inside the electric grill. The ion needles generate high temperatures during operation. The airflow from the cross-flow fan 11 effectively removes the heat around the ion needles, dissipating it and preventing overheating from affecting their discharge performance. This ensures the ignition stability and normal flame of the electric grill. After the electric grill has been used for a period of time, a certain amount of impurities will accumulate on the filter plate 21. To ensure the filtration effect, the filter plate 21 needs to be cleaned or replaced regularly. Loosen the fixing components, remove the filter plate 21, rinse it with clean water to remove surface impurities, and after the filter plate 21 is dry, reinstall it at the air inlet or replace it with a new one and install it directly at the air inlet, securing it firmly with the fixing components.
