Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, in particular to a heat dissipation system and cooking equipment thereof. Background Art

[0002] When cooking is completed and the door of the steam oven is opened, a large amount of water vapor will instantly rush out from the cavity towards the user's face. At the very least, it will blur the user's vision, and at worst, it will scald the user. In addition, the large amount of steam will make the kitchen smoky and increase the humidity of the kitchen air. In the long run, there is a risk of water vapor corroding furniture and appliances.

[0003] To address this issue, a door-opening steam reduction technology module has been added to the oven. This module blows cold air into the oven cavity before the user opens the door, lowering the temperature and pre-expelling some high-temperature water vapor. The solenoid valve assembly in this module is constantly exposed to high temperatures during use. The solenoid valve shaft seal is in direct contact with the hot air in the cavity, transferring heat from the cavity to the solenoid valve shaft. The solenoid valve coil itself also heats up during operation. This combined heat ultimately causes the solenoid valve assembly to exceed the specified temperature during use.

DETAILED DESCRIPTION

[0029] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific embodiments of the present invention or equivalent replacements of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed in the present invention.

[0030] Example 1

[0031] refer to Figure 1-5 This embodiment provides a heat dissipation system, including an air distribution device (not shown in the figure) and a fan assembly 4, wherein the air distribution device includes a fixed bracket 1, a power component 2 and a seal 3. The fixed bracket 1 is provided with an air inlet channel 111, an air outlet 112 and an axis hole 113 with a front opening. The air outlet 112 and the axis hole 113 are respectively connected to the air inlet channel 111, and the air outlet 112 is used to connect with the inner pot of the cooking device. The power component 2 is arranged outside the fixed bracket 1 and is detachably connected to the fixed bracket 1. The power component 2 is a solenoid valve or a motor. In this embodiment, the power component 2 is taken as an example of a solenoid valve. The power component 2 is provided with a connecting shaft 21 extending toward the fixed bracket 1. The connecting shaft 21 passes through the axis hole 113 and extends into the air inlet channel 111. A ventilation gap (not shown in the figure) is left between the hole wall of the axis hole 113 and the outer surface of the connecting shaft 21. The seal 3 is movably disposed within the air inlet passage 111 and connected to the free end of the connecting shaft 21. Driven by the power component 2, the seal 3 can switch between closing the air outlet 112 and opening the shaft hole 113, and opening the air outlet 112 and closing the shaft hole 113, thereby enabling the seal 3 to move between closing the air outlet 112 and closing the shaft hole 113. The fan assembly 4 is disposed outside the fixed bracket 1, and its air outlet is connected to the air inlet passage 111.

[0032] refer to Figure 4When seal 3 closes air outlet 112 and opens shaft hole 113, fan assembly 4 blows cool air into fixed bracket 1. However, due to the closed air outlet and open shaft hole, the cool air inside fixed bracket 1 cannot be blown toward the air outlet. Instead, it can only be blown toward power component 2 through the ventilation gap between shaft hole 113 and connecting shaft 21, thereby cooling and dissipating heat from power component 2. Because the air outlet is closed by seal 3, the high-temperature air generated by the cooking equipment cannot flow into fixed bracket 1 through air outlet 112. Fan assembly 4 continuously blows cool air into fixed bracket 1, creating a normal air pressure inside fixed bracket 1, thereby preventing the high-temperature air generated by the cooking equipment from pushing past seal 3 and entering fixed bracket 1.

[0033] refer to Figure 5 When the seal 3 opens the air outlet 112 and closes the shaft hole 113, the fan assembly 4 blows cold air into the fixed bracket 1. At this time, since the air outlet is open and the shaft hole is closed, the cold air in the fixed bracket 1 can only be blown into the air outlet and then into the inner pot of the cooking device. The cold air squeezes the high-temperature gas in the inner pot and also speeds up the discharge speed of the high-temperature gas in the inner pot, thereby reducing the gas temperature in the inner pot as a whole, achieving less steam when the door is opened, thereby avoiding a large amount of high-temperature water vapor blowing in the face when the door of the cooking device is opened after cooking is completed, thereby improving user safety. Because the shaft hole is closed by the seal, the high-temperature gas cannot pass through the ventilation gap between the shaft hole and the connecting shaft to blow toward the power component 2, causing the power component 2 to fail, which is beneficial to increasing the service life of the power component.

[0034] As can be seen, by cooperating with the fan assembly 4 and the air distribution device, the same fan assembly 4 can be used to cool the power component 2 or the inner pot of the cooking device without increasing costs, thus resolving the issues of steam blowing in the face when the cooking device door is opened and excessive temperature rise of the power component during use. Furthermore, compared to the technical solution of adding a cooling fan to dissipate heat separately from the power component 3, the cooling system of this embodiment has a simpler structure and lowers manufacturing and maintenance costs.

[0035] refer to Figure 1-6 Specifically, the shaft hole 113 and the air outlet 112 are coaxially arranged on the left and right side walls of the fixed bracket 1. The free end of the air outlet 112 protrudes outward from the right side wall of the fixed bracket 1. One end of the air outlet 112 is connected to the outlet end of the air inlet channel, and the other end is used to connect to the inner pot of the cooking device through the second connecting pipe 72. The shaft hole 113 is directly connected to the outlet end of the air inlet channel 111. At least two downwardly extending support portions 12 are integrally formed at the bottom of the fixed bracket 1. The support portions 12 are used for detachable connection with the cooking device.

[0036] refer to Figure 3-5Specifically, the power component 2 is arranged outside the left side of the fixed bracket 1, and a gap (not shown in the figure) is left between the power component 2 and the left outer side wall of the fixed bracket 1. The gap is connected to the ventilation gap. In this way, when the cold air flows out of the ventilation gap, it disperses and flows along the gap, which is conducive to increasing the contact area between the cold air and the power component 2, thereby improving the heat dissipation and cooling effect. Two mounting portions 22 extending outward and arranged oppositely are provided at one end of the power component 2 close to the fixed bracket 1. In this embodiment, the two mounting portions 22 are respectively located at the top and bottom of the power component. A connecting portion 13 is provided at the position of the fixed bracket 1 corresponding to the mounting portion 22. The connecting portion 13 and the mounting portion 22 are detachably connected by screws to achieve a reliable connection of the power component 3 to the fixed bracket.

[0037] refer to Figure 4-7 Specifically, the seal 3 includes a sealing body 31, a first sealing portion 32 and a second sealing portion 33. The sealing body 31 is arranged in the air inlet channel 111 of the fixed bracket 1 and is sleeved on the free end of the connecting shaft 21. The first sealing portion 32 is integrally formed and arranged on the side of the sealing body 31 facing the air outlet 112, and is used to open or close the air outlet 112. The second sealing portion 33 is integrally formed and arranged on the side of the sealing body 31 facing the shaft hole 113, and is used to open or close the shaft hole 113.

[0038] In this embodiment, an annular groove is formed between the first sealing portion 32 and the second sealing portion 33, located on the periphery of the sealing body 31 and opening outward. The first sealing portion 32 and the second sealing portion 33 are both annular in structure and include a flared edge 321 extending from the sealing body 31 toward the radially outer side of the sealing body 31. The flared edge 321 forms the groove wall of the annular groove. In addition, the first sealing portion 32 and the second sealing portion 33 also include a constricted edge 322 extending from the flared edge 321 toward the central axis of the sealing body 31. The constricted edge 322 and the flared edge 321 enclose a deformable cavity in the shape of a "U" or "V", see Figure 7 , thereby increasing the deformability of the first sealing portion 32 and the second sealing portion 33, thereby improving the sealing performance of the seal 3 on the air outlet or shaft hole. In particular, in other embodiments, the necked edges 322 in the first sealing portion 32 and the second sealing portion 33 can be omitted.

[0039] In this embodiment, the sealing body 31 is provided with a mounting hole (not shown) that opens toward the connecting shaft 21. The free end of the connecting shaft 21 extends into the mounting hole and is connected to the sealing body 31. The mounting hole includes a T-shaped engaging hole 311 and a through hole 312. The diameter of the engaging hole 311 is larger than the diameter of the through hole. The free end of the connecting shaft 21 passes through the through hole 312 and extends into the engaging hole 311. A engaging portion 211 is provided at the free end of the connecting shaft 21. The engaging portion 211 engages with the engaging hole 311 to ensure that the seal 3 is stably and reliably connected to the outside of the connecting shaft and prevent the seal from being dislodged from the connecting shaft. In addition, an outwardly extending limiting portion 212 is provided at the free end of the connecting shaft 21. The limiting portion 212 is located between the mounting hole and the shaft hole 113 and is used to limit the position of the seal 3 to limit the installation depth between the connecting shaft and the seal 3.

[0040] refer to Figure 1-5 The air distribution device also includes a temperature measuring component 5 and / or an air inlet connector 6. The fixed bracket 1 is provided with an assembly hole 141 that communicates with the air inlet channel 111. The temperature measuring component 5 is preferably a thermostat, which is mounted at the assembly hole 141 and sealed to the fixed bracket 1 for detecting the temperature of the air inlet channel 111. When the seal 3 opens the air outlet, if the temperature measuring component 5 detects that the temperature within the air inlet channel of the fixed bracket 1 exceeds the initial set temperature, an abnormality signal is fed back to the main control board of the cooking device, an error message alerting the user of an abnormality in the fan assembly 4. This prevents a large amount of high-temperature water vapor and high-temperature gas within the cooking pot of the cooking device from being supplied to the heat dissipation system and overflowing from the cooking pot, thereby facilitating timely maintenance of the fan assembly 4. In this embodiment, a plurality of fixing posts 142 extending outward and located outside the assembly hole 141 are integrally formed on the outer wall of the fixed bracket 1. The temperature measuring component 5 is fastened to the plurality of fixing posts 142 via fasteners (e.g., screws) to enable the temperature measuring component 5 to be removably mounted on the fixed bracket. In addition, a sealing structure is provided between the fixing bracket and the temperature measuring component 5 to prevent air leakage at the connection.

[0041] The air inlet connector 6 is detachably mounted on the fixed bracket 1 and is sealed therewith. The air supply port of the fan assembly 4 is connected to the air inlet passage 111 via the air inlet connector 6. In this embodiment, the air inlet connector 6 includes a cover plate 61 and an air inlet 62. The cover plate 61 is mounted on the front end of the fixed bracket 1 and covers the front end opening of the air inlet passage 111. A sealing structure is provided between the cover plate 61 and the fixed bracket. The cover plate 61 is provided with an air inlet 62 that is connected to the air inlet passage. The air supply port of the fan assembly 4 is connected to the air inlet 62 via a first connecting pipe 71.

[0042] In this embodiment, a snap-fit ​​structure is provided between the air inlet connector 6 and the fixed bracket 1. The snap-fit ​​structure includes a snap-fit ​​hole 631 and a snap-fit ​​portion 15. Multiple extensions 63 extending toward the fixed bracket 1 and arranged at intervals are integrally formed on the cover plate 61 of the air inlet connector 6. The extensions 63 are located on the outside of the side wall of the fixed bracket 1 and are provided with snap-fit ​​holes 631. The snap-fit ​​portion 15 is provided on the outer wall of the fixed bracket 1 at positions corresponding to the openings and closing holes. The snap-fit ​​portion 15 engages with the corresponding snap-fit ​​hole. In other embodiments, the air inlet connector 6 and the fixed bracket 1 can be detachably connected via threads or connectors.

[0043] Example 2

[0044] refer to Figure 8 This embodiment provides a cooking device, which is a steam oven or oven, comprising a cavity assembly 8 and a heat dissipation system as described in Example 1. The cavity assembly 8 includes an inner container with an opening on one side, a cold air inlet, and an exhaust port, the inner container being connected to the cold air inlet and exhaust ports, respectively. The heat dissipation system is disposed outside the cavity assembly 8, and the air outlet 112 is connected to the inner container via a second connecting pipe 72 and the cold air inlet, in sequence.

[0045] refer to Figure 4 During cooking, the power component (e.g., solenoid valve) is de-energized, and the connecting shaft 21 drives the seal 3 toward the air outlet 112, closing the air outlet 112 and opening the shaft hole 113. The fan assembly 4 then starts, drawing in cool air and blowing it into the fixed bracket 1 through the first connecting pipe 71. The cool air is then blown from the shaft hole 113 toward the power component (e.g., solenoid valve) to cool and dissipate heat for the solenoid valve. At this point, the seal 3, driven by the connecting shaft 21, seals the air outlet 112 of the fixed bracket 1, preventing high-temperature water vapor and high-temperature gas from escaping from the inner container. As the fan assembly 4 continuously blows cool air into the fixed bracket 1, a normal air pressure is formed within the air inlet passage 111, effectively preventing the high-temperature gas from pushing past the seal 3 and escaping from the inner container.

[0046] refer to Figure 5 After the cooking device finishes cooking, the fan assembly 4 starts to absorb cold air and blows the cold air into the air inlet channel of the fixed bracket 1 through the first connecting pipe 71. At this time, the power component (such as the solenoid valve) is powered on and the connecting shaft 21 drives the seal 3 to move away from the air inlet, so that the seal 3 opens the air outlet 112 and closes the shaft hole 113. The cold air blown into the fixed bracket 1 by the fan assembly 4 passes through the air outlet 112, the second connecting pipe 72, and the cold air inlet in turn into the inner tank for cooling. Since the seal 3 seals the shaft hole 113, it can prevent the high-temperature water vapor and high-temperature gas overflowing from the inner tank from blowing toward the solenoid valve and causing the solenoid valve to fail.

[0047] When the cooking device has finished cooking and the fan assembly 4 fails, the seal 3 opens the air outlet 112 and closes the shaft hole 113. Due to the failure of the fan assembly 4, a large amount of high-temperature water vapor and high-temperature gas in the inner tank will enter the air inlet channel 111 of the fixed bracket 1 through the second connecting pipe 72. At this time, the temperature measuring component 5 installed on the fixed bracket 1 detects that the temperature in the air inlet channel exceeds the initial set temperature, and feeds back the abnormal signal to the main control board to report an error and remind the user that the fan assembly 4 is abnormal, so as to prevent a large amount of high-temperature water vapor and high-temperature gas in the inner tank from overflowing to the outside of the inner tank.

[0048] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
