Description

Technical Field

[0001] The invention relates to a heat dissipation system and a cooking device comprising the same. Background Art

[0002] Cooking products that combine cooking and steaming, such as steamers, ovens, and steam-and-bake equipment, require high heat dissipation characteristics. For example, the stove of a stove-steam-and-bake product is directly covered on the steam-and-bake oven, which means that the dehumidification and heat dissipation functions of the steam-and-bake oven will be hindered, so its dehumidification and heat dissipation functions need to be considered. In the prior art, a set of air inlet components is usually provided, and the end is connected to a condensate box. An exhaust duct is provided below the condensate box to connect to the exhaust end of the steam-and-bake oven at the bottom, thereby generating air flow through the air intake of the air inlet component, and discharging steam and heat from the holes above the condensate box to achieve dehumidification and heat dissipation. For example, the steamer disclosed in CN218852441U is provided with an exhaust duct and an exhaust fan as an air inlet component, and a condensation device as a condensate box.

[0003] However, in the prior art, due to factors such as space constraints and industrial design, the flow performance of the entire system has been ignored, and the opening above the condensate box has size restrictions, so the air outlet pressure there is relatively high. Part of the airflow here will sink along the inner wall of the condensate box to the exhaust end at the bottom, resulting in increased resistance in the exhaust end, which in turn blocks the air outlet of the cooking equipment below. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defect that the heat dissipation system of the cooking equipment in the prior art has poor exhaust performance, which easily leads to the obstruction of the exhaust of the cooking equipment.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] A heat dissipation system includes a condensate box, an exhaust port arranged at the bottom of the condensate box, and an air inlet assembly connected to the condensate box, the heat dissipation system also includes an air outlet cover plate, the air outlet cover plate is arranged at the top of the condensate box and has a plurality of air outlet grille holes open outward, the side of the condensate box is provided with a plurality of air inlet grille holes connected to the air inlet assembly, wherein the positions of the air inlet grille holes and the air outlet grille holes match in the air inlet direction of the air inlet assembly, and the corresponding dimensions of the air inlet grille holes and the air outlet grille holes along the height direction are smaller than the dimensions along the width direction.

[0007] In this solution, the air inlet grille holes and the air outlet grille holes extend more in the height direction and can be arranged more in the width direction. Compared with the larger size in the width direction, this solution is more conducive to increasing the total cross-sectional area of ​​the flow and greatly increasing the total flow of the system. In addition, multiple air inlet grille holes are conducive to the airflow entering the condensate water box for diversion, and guide the airflow to flow evenly to the corresponding air outlet grille holes above, thereby improving the heat dissipation efficiency. Vertical strip openings with more sizes along the height direction can cause the airflow to generate a pressure gradient in the condensate water box. The airflow velocity at the top is higher and the pressure is lower than that of the airflow at the bottom. Therefore, a pressure gradient is formed in the cavity, guiding the airflow to exhaust upwards, rather than sinking or stagnating in the condensate water box to generate large resistance and affect the system's dehumidification and heat dissipation.

[0008] Preferably, the center line of each of the air inlet grille holes is in the same plane as the center line of the corresponding air outlet grille hole. This arrangement allows the airflow entering the air inlet grille hole to be more directly aligned with the air outlet grille hole and discharged, thereby increasing flow efficiency and reducing the amount of airflow that is blocked and sinks.

[0009] Preferably, the number of the outlet grille holes is greater than the number of the inlet grille holes, wherein the center lines of some of the outlet grille holes are not in the same plane as the center line of the inlet grille, and / or the center lines of each inlet grille hole are in the same plane as the center lines of the corresponding plurality of outlet grille holes. Additional outlet grille holes can increase the exhaust capacity.

[0010] Preferably, the air inlet grille holes and / or the air outlet grille holes are aligned along the width direction, thereby making it easier to align the positions of the air inlet grille holes and the air outlet grille holes.

[0011] Preferably, the inner wall surface of the condensed water box on the side away from the air intake grille hole is an arc shape with a slope. After a part of the air intake assembly's air intake hits the inner wall surface on the side away from the air intake grille hole, the arc shape can lift this part of the air and discharge it upward.

[0012] Preferably, the air intake grille holes are divided into multiple groups in the width direction, and the spacing distance between adjacent air intake grille holes in each group in the width direction is greater than the spacing distance between the air intake grille holes in each group in the width direction. In this way, the air intake of the air intake assembly can be more dispersed, which is further conducive to the airflow entering the condensate box for diversion.

[0013] Preferably, the outlet cover plate is further provided with a plurality of auxiliary grille holes, the dimension of the auxiliary grille holes along the height direction is smaller than the dimension along the width direction, and the auxiliary grille holes are located on the side of the outlet cover plate away from the inlet grille holes, and the auxiliary grille holes are separated from or integrated with the outlet grille holes. The airflow that impacts the inner wall surface of the condensed water box on the side away from the inlet grille holes can be better discharged by the auxiliary grille holes, thereby improving the efficiency of exhaust heat dissipation.

[0014] Preferably, the extension distance of the auxiliary grille hole in the width direction covers each of the air intake grille holes, thereby covering and discharging the airflow that impacts the inner wall surface of the condensation water box away from the air intake grille holes to the greatest extent.

[0015] Preferably, the auxiliary grille holes are integrated with the air outlet grille holes on one or both sides in the width direction to form an L-shape. The L-shaped holes on the side can collect and discharge the internal diffused airflow in a larger range, while having less impact on the overall strength.

[0016] Preferably, the air intake assembly comprises an air intake duct and an air intake device for generating air flow, and two ends of the air intake duct are respectively connected to the air intake device and the air intake grille hole.

[0017] Preferably, the air inlet duct has a main section and a transition section, two sides of the transition section are respectively connected to the main section and the air inlet grille hole, and two sides of the main section are respectively connected to the air inlet device and the transition section.

[0018] Preferably, the connection between the main body section and the transition section has an air inlet section, the connection between the transition section and the air inlet grille hole has an air outlet section, and the sections of the transition sections between the air inlet section and the air outlet section decrease and shrink. As a result, the resistance of the fluid outlet in the transition section is reduced, the vortex and flow separation are significantly reduced, and the flow rate is increased, so the total flow of the system will be increased, which is conducive to reducing the system flow loss and improving the heat dissipation efficiency of the system.

[0019] Preferably, the cross-sections of the transition sections from the air inlet cross-section to the air outlet cross-section shrink in a proportional decreasing relationship, which can simplify the cross-section design of the transition section on the one hand, and is also conducive to gradual transition and increased flow rate on the other hand.

[0020] Preferably, the side of the condensate box has a gradual slope extending outward, the side end of the transition section is open and connected to the side wall of the condensate box, and the bottom end of the transition section is open and connected to the gradual slope. On the one hand, the gradual slope can bear the weight of the transition section and provide a support point for fixation. On the other hand, the surface shape of the gradual slope is easier to shape than the pipe, so it is convenient to constrain the internal cross-sectional shape as the bottom shape of the transition section.

[0021] A cooking device comprises a cooking unit, the cooking device comprises the heat dissipation system, wherein the cooking unit is communicated with the exhaust end to exhaust internal steam.

[0022] The positive progress of the present invention is that the present invention is conducive to increasing the total cross-sectional area of ​​the flow, greatly increasing the total flow of the system. It can also guide the airflow to flow evenly to the corresponding air outlet grille holes above, improving the heat dissipation efficiency. It also forms a pressure gradient in the cavity, guiding the airflow to be discharged upward, rather than sinking or stagnating in the condensation water box to generate large resistance and affect the dehumidification and heat dissipation of the system.

[0051] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0052] like Figure 1-Figure 3 As shown, a preferred embodiment of the present invention discloses a heat dissipation system, including a condensed water box 100, an exhaust port 120 arranged at the bottom of the condensed water box 100, and an air inlet assembly 200 connected to the condensed water box 100, the heat dissipation system also includes an air outlet cover plate 300, the air outlet cover plate 300 is arranged on the top of the condensed water box 100 and has a plurality of air outlet grille holes 310 open to the outside, and a plurality of air inlet grille holes 110 connected to the air inlet assembly 200 are arranged on the side of the condensed water box 100, wherein, as shown in FIG. Figure 3 As shown, the air inlet grille holes 110 and the air outlet grille holes 310 match each other in the air inlet direction of the air inlet assembly 200, and the corresponding air inlet grille holes 110 and air outlet grille holes 310 have smaller dimensions along the height direction a than along the width direction b.

[0053] like Figure 1 and Figure 2As shown, the air intake assembly 200 of this embodiment is connected to the air intake grille hole 110 by sealingly connecting to the side wall of the condensate box 100. In other embodiments, the air intake assembly 200 can be connected to the air intake grille hole 110 in various known ways. In addition, the air outlet cover plate 300 of this embodiment can be fixedly connected to the condensate box 100 as a whole, or can be a detachable split connection relationship.

[0054] like Figure 3 As shown, the position matching of the air inlet grille hole 110 and the air outlet grille hole 310 in the air inlet direction of the air inlet assembly 200 in this embodiment refers to the position setting so that the air inlet of the air inlet grille hole 110 can be smoothly discharged from the air outlet grille hole 310. In some embodiments, the air inlet grille hole 110 and the air outlet grille hole 310 can be completely aligned, so that the air inlet of the air inlet grille hole 110 is directly aligned with the air outlet grille hole 310 for discharge. In some other embodiments, it is also possible not to be completely aligned, but to ensure that after the air inlet of the air inlet grille hole 110 is diffused in the condensed water box 100, the position of the air outlet grille hole 310 can cover the area where most of the diffused airflow is located, so that the airflow can be guided to be discharged.

[0055] like Figure 3 As shown, the number of the air inlet grille holes 110 and the air outlet grille holes 310 in this embodiment is inconsistent. In some embodiments, the number of the two can also be set to be consistent. In some preferred embodiments, the coverage area of ​​the arrangement of the air outlet grille holes 310 is larger than the coverage area of ​​the air inlet grille holes 110 to collect and discharge some airflow that escapes from the condensed water box 100, for example, through more air inlet grille holes 110 or making the distribution distance of the air inlet grille holes 110 larger. However, in some other embodiments, it is not limited to making the coverage area of ​​the air outlet grille holes 310 larger.

[0056] like Figure 3 As shown, the width direction b in this embodiment is the width direction of the condensate box 100, the height direction a of the air inlet grille hole 110 is the height direction of the condensate box 100, and the height direction a of the air outlet grille hole is the depth direction of the condensate box 100. Of course, in other embodiments, as the shape of the condensate box 100 changes, the height direction a and the width direction b and the dimensional direction of the condensate box 100 will change. But overall, the height direction a of the air inlet grille hole 110 and the air outlet grille hole 310 extends along the path of the air flow direction, so as to allow more gas to enter and exit along the air flow direction, and the width direction b of the air inlet grille hole 110 and the air outlet grille hole 310 is perpendicular to or different from the height direction a, so as to cover more areas.

[0057] In the present invention, the air inlet grille holes 110 and the air outlet grille holes 310 extend more in the height direction a, and can be arranged more in the width direction b. Compared with the larger size in the width direction b, this solution is more conducive to increasing the total flow cross-sectional area and greatly improving the total flow of the system. In addition, multiple air inlet grille holes 110 are conducive to the airflow entering the condensate box 100 for diversion, and guide the airflow to flow evenly to the corresponding air outlet grille holes 310 above, thereby improving the heat dissipation efficiency. Figure 7 As shown in the schematic diagram, vertical openings of more sizes along the height direction a can make the airflow shown by the arrow generate a pressure gradient in the condensate box 100. The airflow velocity at the top is higher and the pressure is lower than that at the bottom. Therefore, a pressure gradient is formed in the cavity, guiding the airflow to exhaust upward instead of sinking or stagnating in the condensate box 100 to generate large resistance and affect the dehumidification and heat dissipation of the system.

[0058] In a preferred embodiment, the center line of each air inlet grille hole 110 can be further arranged in the same plane as the center line of the corresponding air outlet grille hole 310. With this arrangement, the airflow entering the air inlet grille hole 110 can be more directly aligned with the air outlet grille hole 310 and discharged, thereby facilitating the increase of flow efficiency and reducing the amount of airflow that is blocked and sinks.

[0059] In a further preferred embodiment, the number of the outlet grille holes 310 is greater than the number of the inlet grille holes 110, wherein the center lines of some of the outlet grille holes 310 are not in the same plane as the center line of the inlet grille, and / or the center lines of each inlet grille hole 110 are in the same plane as the center lines of the corresponding plurality of outlet grille holes 310. Additional outlet grille holes 310 can increase the exhaust capacity.

[0060] like Figure 3 As shown, in this embodiment, the air intake grille holes 110 and / or the air outlet grille holes 310 are aligned along the width direction b. This makes it easier to align the positions of the air intake grille holes 110 and the air outlet grille holes 310. The alignment in this embodiment refers to the alignment of the centers of the air intake grille holes 110 and / or the air outlet grille holes 310 arranged in the width direction b, or the alignment of the two ends. When the air intake grille holes 110 and the air outlet grille holes 310 are aligned, the air intake and air outlet of both can be accurately set, ensuring that the air intake and air outlet at each position along the width direction b can maintain a uniform distribution. In other embodiments, it is not limited to the alignment in the width direction b.

[0061] like Figure 3As shown, in a preferred embodiment, the air intake grille holes 110 are divided into multiple groups in the width direction b, and the spacing distance between adjacent air intake grille holes 110 in the width direction b between each group is greater than the spacing distance between the air intake grille holes 110 in the width direction b within each group. Thus, the air intake of the air intake assembly 200 can be more dispersed, which is further conducive to the airflow entering the condensed water box 100 for diversion.

[0062] like Figure 3 As shown, in a preferred embodiment, the outlet cover plate 300 is further provided with a plurality of auxiliary grille holes 320, the size of the auxiliary grille holes 320 along the height direction a is smaller than the size in the width direction b, and the auxiliary grille holes 320 are located on the side of the outlet cover plate 300 away from the inlet grille holes 110, and the auxiliary grille holes 320 are separated from or integrated with the outlet grille holes 310. The airflow that impacts the inner wall surface 130 of the condensed water box 100 away from the inlet grille holes 110 can be better discharged by the auxiliary grille holes 320, thereby improving the efficiency of exhaust heat dissipation.

[0063] like Figure 3 As shown, in a further preferred embodiment, the extension distance of the auxiliary grille hole 320 in the width direction b covers each air intake grille hole 110. Thus, the airflow impacting the inner wall surface of the condensation water box 100 away from the air intake grille hole 110 can be covered and discharged to the greatest extent.

[0064] like Figure 3 As shown, in a further preferred embodiment, the auxiliary grille holes 320 are integrated with the air outlet grille holes 310 located on one or both sides of the width direction b into an L-shape. The L-shaped holes located on the side can collect and discharge the internal diffused airflow in a larger range, while having less impact on the overall strength.

[0065] like Figure 4 and Figure 5As shown, in a preferred embodiment, the condensate box 100 preferably has a surrounding wall 150 inside, and the surrounding wall 150 is arranged along the periphery of the upper port 121 of the exhaust end 120 as a whole, and forms a gap with the surrounding inner wall of the condensate box 100. Among them, the height of the upper port 121 is higher than the bottom surface of the condensate box 100, so that the condensate is not easy to enter the exhaust end 120 through the upper port. The coverage range of the projection of the surrounding wall 150 does not exceed the coverage range of the projection of the air outlet grille hole 310 above, so that the airflow gathered in the internal space of the surrounding wall 150 is discharged upward through the air outlet grille hole 310 as much as possible. The condensate caused by the airflow escaping at other positions can be blocked by the surrounding wall 150 to reduce the condensate near the upper port 121. In addition, the surrounding wall 150 is set to a concave notch shape at the position of the air intake grille hole 110 to allow the airflow to directly enter and drive the hot air gathered in the surrounding wall 150 to be discharged upward.

[0066] like Figure 6 and Figure 7 As shown, in a preferred embodiment, the inner wall surface 130 of the condensation water box 100 away from the air intake grille hole 110 can be transformed into a curved surface shape with a slope ( Figure 6 and Figure 7 Indicated by dotted lines). Figure 7 As shown, after a portion of the air intake assembly 200 enters through the air intake grille hole 110 and impacts the inner wall surface 130 on the side away from the air intake grille hole 110, the arc shape can lift this portion of the air and discharge it upward, thereby improving the discharge capacity of the airflow. Figure 7 As shown, the overall airflow enters the cavity of the condensate box 100 obliquely from the air inlet grille hole 110 and flows to the air outlet grille hole 310, so the air outlet pressure close to the air inlet grille hole 110 is relatively small, and most of the air outlet is mainly concentrated on the side away from the air inlet grille hole 110. Therefore, the L-shaped fused air outlet grille hole 310 and the auxiliary grille hole 320 combined with the optimized inner wall structure can maximize the use of the flow cross-sectional area, and effectively guide the airflow to the outside to exhaust, reduce the amount of airflow that generates flow separation, and thus improve the overall heat dissipation performance and moisture removal performance of the system. In some embodiments, the inner wall surface 130 can be a curved surface shape with a slope formed by the entire condensate box 100, or a curved surface shape with a curvature formed only at the inner wall surface 130.

[0067] like Figure 1-Figure 7As shown, the air intake assembly 200 of this embodiment further includes an air intake duct 220 and an air intake device 210 for generating air flow, and the two ends of the air intake duct 220 are respectively connected to the air intake device 210 and the air intake grille hole 110. Among them, the air intake device 210 can be a known device for generating wind pressure such as a fan, and the air intake duct 220 can be a pipe-shaped structure. The air intake device 210 and the gold powder duct 220 are connected in an integrated form or in a separate connection form.

[0068] like Figure 6 and Figure 7 As shown, in a preferred embodiment, the air inlet duct 220 may further include a main section 222 and a transition section 221, the two sides of the transition section 221 are respectively connected to the main section 222 and the air inlet grille hole 110, and the two sides of the main section 222 are respectively connected to the air inlet device 210 and the transition section 221. The transition section 221 may be formed integrally with the main section 222, or may be connected in a separate form. The transition section 221 may change in cross section or change in vertical and horizontal positions at both ends, thereby adapting to changes in the cross section or position of the main section 222 and the air inlet grille hole 110.

[0069] like Figure 6 and Figure 7 As shown, the transition section 221 of this embodiment has an air intake cross section c at the junction with the main section 222, and the transition section 221 has an air outlet cross section d at the junction with the air intake grille hole 110. The cross section of each transition section 221 from the air intake cross section c to the air outlet cross section d ( Figure 6The schematic diagram in FIG. 2 shows that the cross sections e and f) shrink in a decreasing manner. As a result, the resistance of the fluid outlet of the transition section 221 is reduced, the vortex and flow separation are significantly reduced, and the flow rate is increased, so the total flow of the system will be increased, which is conducive to reducing the flow loss of the system and improving the heat dissipation efficiency of the system. When it is not set in this way, in some cases, the cross sections of the transition section 221 from the air inlet duct 220 to the condensate box 100 are sometimes large and sometimes small, and the angle at the corner is too large. Such a structure easily causes the airflow passing through here to separate, and the excess airflow will flow back and form a vortex at the corner, causing flow loss and affecting the heat dissipation efficiency. This form of flow cross-section that is sometimes large and sometimes small guides the airflow from the relatively narrow air inlet duct 220 into the interior of the relatively wide condensate box 100. It will separate more airflow to various places inside the condensate box 100. Some of the airflow will hit the inner wall of the condensate box 100 straightly and sink, while some of the air will stay inside the condensate box 100. In addition, the resistance of the top air outlet cover 300 will hinder the gas from being exhausted to the outside, causing the exhaust pressure at the lower exhaust end 120 to increase, affecting the dehumidification function of the system. By making the entire transition section 221 present a contracting streamline shape, the airflow is controlled to be evenly discharged in the direction of the air outlet cover 300 without being blocked from sinking. As a result, the vortex and flow separation at the transition section 221 are significantly reduced, and the airflow is guided to be discharged in the direction of the air outlet cover 300, which helps to reduce the system flow loss and improve the heat dissipation efficiency of the system. Figure 6 The shape of the transition section 221 can be set in the form of each cross section gradually shrinking in accordance with the vertical plane, or in the form of the cross section perpendicular to the air inlet direction gradually shrinking. In the case of gradually shrinking the whole, the airflow can be gathered.

[0070] In a preferred embodiment, the cross-sections of each transition section 221 from the air inlet cross-section c to the air outlet cross-section d (c to e to f to d) can be further reduced in a proportional decreasing relationship. This can simplify the cross-section design of the transition section 221 on the one hand, and is also conducive to gradual transition and increased flow rate on the other hand. Of course, in other embodiments, the reduction can also be performed according to other reduction relationships. The overall decreasing relationship can include a certain degree of increase or no reduction in the cross-section of a limited number of local positions, but the overall change trend needs to present a contraction shape.

[0071] like Figure 6 and Figure 7As shown, in a preferred embodiment, the side of the condensate box 100 has a progressive slope 140 extending outward, the side end of the transition section 221 is open and connected to the side wall of the condensate box 100, and the bottom end of the transition section 221 is open and connected to the progressive slope 140. On the one hand, the progressive slope 140 can bear the weight of the transition section 221 and provide a support point for fixation. On the other hand, the surface shape of the progressive slope 140 is easier to shape than the pipe, so it is convenient to constrain the internal cross-sectional shape as the bottom shape of the transition section 221. The upper surface shape of the progressive slope 140 can be changed and set according to the contraction relationship of the cross section of the transition section 221 to be achieved. For example, in the cross-section cf section, the progressive slope 140 can be a slope shape similar to an inclined slope, which is compared with the surface of the corresponding upper transition section 221, which tends to gradually approach each other, thereby reducing the cross section. In the cross-section fd section, the progressive slope 140 tends to be gentle so that the airflow can enter the air intake grille hole 110 in a relatively horizontal manner. The progressive slope 140 can be integrally formed with the condensate box 100, for example, by injection molding of a polymer material, so that the progressive slope 140 is easy to produce and the precision of the surface change is easy to control. The air inlet duct 220 can be implemented by a sheet metal structure, etc., and even if the precision is slightly poor, it is not easy to have a large deviation after being combined with the progressive slope 140.

[0072] like Figure 8 The figure shows several different arrangements of the air outlet grille holes 310 and the auxiliary grille holes 320 . Figure 8 The first way from top to bottom is, for example Figure 1-Figure 3 In the form shown, the air outlet grille holes 310 are divided into two groups, and auxiliary grille holes 320 are arranged on one side of the air outlet grille holes 310. The auxiliary grille holes 320 and the side air outlet grille holes 310 form an L shape. Figure 8 In the second method from top to bottom, the air outlet grille holes 310 are divided into two groups, and auxiliary grille holes 320 are provided on one side of the air outlet grille holes 310. The difference from the first method is that the auxiliary grille holes 320 are relatively independently provided and are not integrated with the air outlet grille holes 310. Figure 8 In the third method from top to bottom, the air outlet grille holes 310 are divided into two groups, and auxiliary grille holes 320 are provided on one side of the air outlet grille holes 310. The difference from the first method is that the auxiliary grille holes 320 on both sides are fused together and fused with the air outlet grille holes 310 on both sides. Figure 8 In the fourth manner from top to bottom, the distances between the air outlet grille holes 310 are relatively large, and the air outlet grille holes 310 are not divided into two groups, and no auxiliary grille hole 320 is arranged on one side of the air outlet grille hole 310 . Figure 8In other embodiments, it is possible to select whether the outlet grille holes 310 and the auxiliary grille holes 320 need to be merged together according to the strength of the area around the outlet grille holes 310, to select whether the outlet grille holes 310 are grouped according to the air flow dispersion requirements, and to select whether to set the auxiliary grille holes 320 according to the straight air flow situation.

[0073] The heat dissipation system of this embodiment can be applied to cooking devices that need to discharge internal heat or steam, and these cooking devices include a cooking unit and the above-mentioned heat dissipation system, wherein the cooking unit is connected to the exhaust port 120 to discharge internal heat or steam. The cooking device can be a steamer, an oven, a steam-bake integrated box, a stove steam-bake device or other similar products.

[0074] When used in stove steaming and baking products, the air inlet assembly 200 can be arranged and fixed under the stove chassis, and the exhaust end 120 can be connected to the exhaust hole of the steaming oven under the stove through a pipe or directly to play a role in heat dissipation. At the same time, a hole is opened on the stove panel to expose the air outlet cover plate 300 on the surface of the stove panel, so that the air outlet grille hole 310 can directly exhaust upward. The condensed water box 100 is placed under the stove panel in a sunken manner. The humid and hot gas from the steaming oven is received by the exhaust end 120 below the condensed water box 100, and the air is brought out of the air outlet grille hole 310 under the air intake of the air inlet assembly 200, thereby forming a dehumidification system to play a dehumidification role. The combination of the air outlet cover plate 300, the air inlet assembly 200 and the condensed water box 100 together constitutes a heat dissipation and dehumidification system for stove steaming and baking products.

[0075] When used in common steam-bake products, an opening can be provided at a portion of the outer shell of the common steam-bake product where air can be easily discharged to accommodate the air outlet cover plate 300. The air inlet assembly 200 is provided between the inner pot and the outer shell of the steam-bake product. The exhaust end is connected to the exhaust hole of the inner pot. Compared with the passive heat dissipation method, this active heat dissipation method can discharge the internal heat more effectively.

[0076] In summary, the present invention is conducive to increasing the total cross-sectional area of ​​the flow, greatly increasing the total flow of the system, and can guide the airflow to flow evenly to the corresponding air outlet grille holes 310 upwards, thereby improving the heat dissipation efficiency. A pressure gradient is formed in the cavity, guiding the airflow to be discharged upwards, rather than sinking or stagnating in the condensed water box 100 to generate large resistance and affect the dehumidification and heat dissipation of the system.

[0077] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
