Description

TECHNICAL FIELD

[0001] The utility model relates to a heat dissipation system and cooking equipment comprising the same. BACKGROUND

[0002] The cooking products such as the integrated product of the stove, the steaming oven and the baking oven, the steaming oven, the baking oven, the integrated equipment of the steaming and baking, and the like, have high requirements on the heat dissipation characteristics. For example, the stove of the integrated product of the stove, the steaming oven and the baking oven is directly covered on the steaming oven and the baking oven, which means that the steam exhaust and heat dissipation functions of the steaming oven and the baking oven will be hindered, and therefore, the steam exhaust and heat dissipation functions need to be considered. In the prior art, a set of air inlet assembly is usually arranged, the end of which is connected to a condensate water box, and an exhaust duct is arranged below the condensate water box to connect the exhaust end of the steaming oven and the baking oven at the bottom, so that the air flow is generated by the air inlet of the air inlet assembly, and the steam and heat are exhausted from the holes above the condensate water box to play the role of steam exhaust and heat dissipation. For example, the steaming oven disclosed in CN218852441U sets the exhaust air duct and the exhaust fan as the air inlet assembly, and sets the condensing device as the condensate water box.

[0003] However, in the prior art, due to the limitation of the space size and the installation mode, the width of the air inlet channel is inconsistent with that of the condensate water box, which causes the air in the air inlet channel to separate quickly in the horizontal width range after entering the condensate water box, resulting in flow loss. The air flow is easy to generate vortex at the condensate water box or the outlet of the air inlet channel, which causes the air outlet of the lower cooking equipment to be blocked. SUMMARY

[0004] The utility model solves the technical problem that the flow of the heat dissipation system of the cooking equipment in the prior art is easy to be lost and vortex is generated, which easily causes the air outlet of the cooking equipment to be blocked.

[0005] The utility model solves the above technical problem by the following technical scheme:

[0006] A heat dissipation system comprises a condensate water box and an air inlet channel communicated with the condensate water box, the condensate water box is provided with air inlet grille holes, the air inlet grille holes are divided into at least two groups and are distributed along the width direction of the condensate water box, the air inlet channel comprises a main channel and at least two branch channels, the outlets of the branch channels are separated from each other, the inlets of the branch channels are communicated with the main channel, the branch channels are distributed along the width direction of the condensate water box, and the outlets of the branch channels are respectively communicated with at least one group of air inlet grille holes.

[0007] In the present scheme, the air inlet channel and the condensate water box are connected by at least two channels, which can reduce the loss of airflow in the lateral range, make the airflow begin to branch before entering the condensate water box, improve the utilization rate of airflow in the lateral range of the condensate water box, accelerate the airflow, improve the air inlet efficiency of the condensate water box, and improve the uniformity of the air outlet of the cover plate, and also avoid the separation of the airflow. The airflow will not flow back from the middle like the integrated air inlet, thereby reducing the vortex at the air inlet of the sub-channel. Thus, the overall flow of the system is improved, the uniformity of the airflow is improved, the air flow to the lower cooking equipment is reduced, and the heat dissipation and dehumidification performance of the system is balanced and optimized.

[0008] Preferably, each air inlet grid hole in one or more groups of air inlet grid holes is distributed along the height direction of the condensate water box. Thus, each sub-channel can expand the air inlet amount by communicating with more air inlet grid holes.

[0009] Preferably, the distance between each sub-channel gradually increases from the inlet of the sub-channel to the outlet of the sub-channel. Thus, most of the airflow can be guided to diffuse to both sides of the condensate water box, improve the uniformity of the flow field in the width direction, reduce the air flow that disperses in all directions after entering the condensate water box, and improve the air outlet flow.

[0010] Preferably, the bottom of the condensate water box is connected with an air outlet interface, and each group of air inlet grid holes is arranged on both sides of the air outlet interface along the width direction of the condensate water box. In order to prevent external food and the like from directly falling into the air outlet interface through the top of the condensate water box and causing blockage, the air outlet interface is usually not provided with an air outlet on the top. The air inlet grid holes arranged on both sides can avoid the airflow being blocked above the air outlet interface and avoid the vortex generated thereby.

[0011] Preferably, the top of the condensate water box is further provided with a cover plate, and the cover plate is provided with air outlet grid holes, and the air outlet grid holes are arranged on both sides of the air outlet interface along the width direction of the condensate water box.

[0012] Preferably, the lower surface of the cover plate is further provided with a flow guide portion, the flow guide portion is located above the air outlet interface, the surface of the flow guide portion is smoothly connected between the air outlet interfaces on both sides, the surface of the flow guide portion is curved, and the height of the flow guide portion gradually decreases from the center to the periphery. The flow guide portion can make the airflow evenly diffuse to the air outlet grid holes on both sides along the curved shape when reaching the position, so as to further reduce the vortex generated by the airflow, improve the uniformity of the flow field, and improve the air outlet flow.

[0013] Preferably, the heat dissipation system comprises a duct component and a wind guide component, wherein the condensate water box is connected with the duct component through the wind guide component, and the main channel is formed in the duct component and the sub-channel is formed in the wind guide component.

[0014] Preferably, the vertical cross-section of each position of the sub-channel is gradually reduced from the inlet of the sub-channel to the outlet of the sub-channel. Thus, the resistance of the fluid outflow of the sub-channel is reduced, the vortex and flow separation are obviously reduced, the flow rate is increased, and therefore the total flow of the system is improved, which is beneficial to reduce the flow loss of the system and improve the heat dissipation efficiency of the system.

[0015] Preferably, the area of the vertical cross-section of each position of the sub-channel is gradually reduced in a positive proportional relationship from the inlet of the sub-channel to the outlet of the sub-channel. Thus, on the one hand, the cross-section design of the transition section can be simplified, and on the other hand, the gradual transition is facilitated and the flow rate is increased.

[0016] A cooking device comprising a cooking unit, the cooking device comprising the heat dissipation system, wherein the cooking unit is in communication with the exhaust interface to exhaust the steam inside.

[0017] The positive progress effect of the utility model lies in: the utility model improves the utilization rate of airflow in the transverse range of the condensate water box to achieve the effects of airflow acceleration, improvement of condensate water box air inlet efficiency and improvement of cover plate air outlet uniformity, and also avoids airflow separation. Also reduces the vortex at the air inlet of the sub-channel. Thus, the overall flow of the system is improved, the uniformity of the airflow is improved, the air flow to the lower cooking device is reduced, the heat dissipation performance and the dehumidification performance of the system are balanced and optimized.

[0038] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0039] like Figures 1-6 As shown, a preferred embodiment of this utility model discloses a heat dissipation system, including a condensate box 200 and an air inlet channel 100 communicating with the condensate box 200. The condensate box 200 is provided with an air inlet grille 220, as shown. Figure 3 The air intake grille openings 220 shown are divided into at least two groups and distributed along the width direction of the condensate box 200, as follows: Figure 4 The air intake channel 100 shown includes a main channel 101 and two branch channels 102. The outlets 102B of each branch channel 102 are separated from each other, and the inlets 102A of each branch channel 102 are connected to the main channel 101. The branch channels 102 are distributed along the width direction of the condensate box 200, and the outlets of each branch channel 102 are connected to at least one set of air intake grille holes 220.

[0040] In this embodiment, the air intake grille holes 220 are divided into two groups along the width direction of the condensate box 200. In other embodiments, the division is not limited to two groups; there can be more groups, with each group distributed along the width direction of the condensate box 200. Simultaneously, the number of sub-channels 102 corresponds to the number of groups in the width direction of the air intake grille holes 220, and there can be multiple sub-channels 102. The outlets 102B of each sub-channel 102 are separate from each other, and the inlets 102A of each sub-channel 102 are all connected to the main channel 101.

[0041] In this embodiment, the main channel 101 and the branch channels 102 refer to the formed connected air ducts, which can be formed by splicing pipes or by forming internal channels within an integrated structure. One end of the main channel 101 is connected to a device that generates airflow, such as a fan 130. Thus, when the fan 130 generates airflow, it flows through the main channel 101 and then into the branch channels 102 on both sides, eventually entering the condensate box 200. The fan 130 is preferably a centrifugal fan.

[0042] In this embodiment, the air inlet channel 100 and the condensate box 200 are connected by at least two channels. This reduces airflow loss in the lateral direction, allowing the airflow to begin splitting before entering the condensate box 200. This improves the utilization rate of the airflow in the lateral direction within the condensate box 200, achieving airflow acceleration, increasing the air intake efficiency of the condensate box 200, and improving the uniformity of air output from the cover plate 300. It also avoids airflow separation. The airflow also avoids backflow from the center like a single air inlet, thus reducing vortices at the air inlet of the split channel 102. This results in increased overall system flow, improved airflow uniformity, reduced airflow back to the cooking equipment below, and a balanced and optimized system performance in terms of heat dissipation and dehumidification.

[0043] like Figure 3 As shown, in a preferred embodiment, the air intake grilles 220 in the two sets of left and right air intake grilles 220 are distributed along the height direction of the condensate box 200. Thus, each sub-channel 102 can increase its air intake volume by communicating with more air intake grilles 220. In some embodiments, the sets of air intake grilles 220 may have different numbers of grilles 220, or different numbers of grilles arranged along the height direction. Alternatively, one set of air intake grilles 220 may have multiple grilles 220 along the height direction, while the other set may have only one grille 220 along the height direction. The distribution of the air intake grilles 220 along the width or height direction corresponds to the coverage area of ​​the outlet 102B of the sub-channel 102, ensuring that the airflow from the outlet 102B can enter each air intake grille 220.

[0044] like Figure 3As shown, in the preferred embodiment, the distance between each sub-channel 102 gradually increases from the entrance of the sub-channel 102 towards the outlet of the sub-channel 102. In this way, most of the airflow can be guided to diffuse to both sides of the condensate box 200, improving the uniformity of the flow field in the width direction, reducing the airflow that spreads everywhere after entering the condensate box 200, and improving the outflow. The distance between the sub-channels 102 can be linearly increased, or in the form shown in the figure, the separation changes more sharply as the outlet 102B of the sub-channel 102 is closer. That is, for example Figure 3 As shown, in the preferred embodiment, the distance between each sub-channel 102 gradually increases from the entrance of the sub-channel 102 towards the outlet of the sub-channel 102. In this way, most of the airflow can be guided to diffuse to both sides of the condensate box 200, improving the uniformity of the flow field in the width direction, reducing the airflow that spreads everywhere after entering the condensate box 200, and improving the outflow. The distance between the sub-channels 102 can be linearly increased, or in the form shown in the figure, the separation changes more sharply as the outlet 102B of the sub-channel 102 is closer. That is, for example Figure 3 As shown, in the preferred embodiment, the distance between each sub-channel 102 gradually increases from the entrance of the sub-channel 102 towards the outlet of the sub-channel 102. In this way, most of the airflow can be guided to diffuse to both sides of the condensate box 200, improving the uniformity of the flow field in the width direction, reducing the airflow that spreads everywhere after entering the condensate box 200, and improving the outflow. The distance between the sub-channels 102 can be linearly increased, or in the form shown in the figure, the separation changes more sharply as the outlet 102B of the sub-channel 102 is closer. That is, for example

[0045] As shown, in the preferred embodiment, the distance between each sub-channel 102 gradually increases from the entrance of the sub-channel 102 towards the outlet of the sub-channel 102. In this way, most of the airflow can be guided to diffuse to both sides of the condensate box 200, improving the uniformity of the flow field in the width direction, reducing the airflow that spreads everywhere after entering the condensate box 200, and improving the outflow. The distance between the sub-channels 102 can be linearly increased, or in the form shown in the figure, the separation changes more sharply as the outlet 102B of the sub-channel 102 is closer. That is, for example Figure 6 As shown, in the preferred embodiment, the distance between each sub-channel 102 gradually increases from the entrance of the sub-channel 102 towards the outlet of the sub-channel 102. In this way, most of the airflow can be guided to diffuse to both sides of the condensate box 200, improving the uniformity of the flow field in the width direction, reducing the airflow that spreads everywhere after entering the condensate box 200, and improving the outflow. The distance between the sub-channels 102 can be linearly increased, or in the form shown in the figure, the separation changes more sharply as the outlet 102B of the sub-channel 102 is closer. That is, for example

[0046] As shown, in the preferred embodiment, the distance between each sub-channel 102 gradually increases from the entrance of the sub-channel 102 towards the outlet of the sub-channel 102. In this way, most of the airflow can be guided to diffuse to both sides of the condensate box 200, improving the uniformity of the flow field in the width direction, reducing the airflow that spreads everywhere after entering the condensate box 200, and improving the outflow. The distance between the sub-channels 102 can be linearly increased, or in the form shown in the figure, the separation changes more sharply as the outlet 102B of the sub-channel 102 is closer. That is, for example Figure 6 As shown, in the preferred embodiment, the distance between each sub-channel 102 gradually increases from the entrance of the sub-channel 102 towards the outlet of the sub-channel 102. In this way, most of the airflow can be guided to diffuse to both sides of the condensate box 200, improving the uniformity of the flow field in the width direction, reducing the airflow that spreads everywhere after entering the condensate box 200, and improving the outflow. The distance between the sub-channels 102 can be linearly increased, or in the form shown in the figure, the separation changes more sharply as the outlet 102B of the sub-channel 102 is closer. That is, for example

[0047] As shown, in the preferred embodiment, the distance between each sub-channel 102 gradually increases from the entrance of the sub-channel 102 towards the outlet of the sub-channel 102. In this way, most of the airflow can be guided to diffuse to both sides of the condensate box 200, improving the uniformity of the flow field in the width direction, reducing the airflow that spreads everywhere after entering the condensate box 200, and improving the outflow. The distance between the sub-channels 102 can be linearly increased, or in the form shown in the figure, the separation changes more sharply as the outlet 102B of the sub-channel 102 is closer. That is, for example Figure 6As shown, in a preferred embodiment, the lower surface of the cover plate 300 is further provided with a guide portion 320. The guide portion 320 is located above the exhaust port 210, and the surface of the guide portion 320 is smoothly connected to the exhaust ports 210 on both sides. The surface of the guide portion 320 is curved, and the height of the guide portion 320 gradually decreases from the center to the periphery. The guide portion 320 allows the airflow to diffuse evenly along the curved shape towards the exhaust grille holes 310 on both sides when it reaches its location, thereby further reducing the vortex formed by the airflow and improving the uniformity of the flow field and the exhaust flow rate. The guide portion 320 can be teardrop-shaped, hemispherical, or other shapes with a height decreasing from the center to the periphery. The guide portion 320 can be integrally formed on the lower surface of the cover plate 300, or it can be fixed to the lower surface of the cover plate 300 by various connection methods.

[0048] like Figures 2-5 As shown, in a preferred embodiment, the air inlet channel 100 of the heat dissipation system includes a pipe component 110 and an air guide component 120. The condensate box 200 is connected to the pipe component 110 via the air guide component 120. A main channel 101 is formed within the pipe component 110, and a branch channel 102 is formed within the air guide component 120. The air inlet channel 100 may also include a fan 130, the air outlet of which is directly connected to the pipe component 110.

[0049] like Figures 2-5 As shown, in a preferred embodiment, the vertical cross-section of each location of the sub-channel 102 gradually decreases from the inlet to the outlet of the sub-channel 102. This reduces the resistance to fluid exiting the sub-channel 102, significantly reduces eddies and flow separation, and increases the flow velocity. Therefore, the total system flow rate is increased, which helps to reduce system flow loss and improve the system's heat dissipation efficiency.

[0050] like Figures 2-5 As shown, in a preferred embodiment, the area of ​​the vertical cross-section at each location of the sub-channel 102 decreases proportionally from the inlet to the outlet of the sub-channel 102. This simplifies the cross-sectional design of the transition section and facilitates a gradual transition, thereby increasing the flow rate.

[0051] The heat dissipation system of this embodiment can be used in various cooking appliances, such as steam ovens, ovens, steam-grill combination appliances, and stove-steam-grill combination appliances. The cooking appliance includes a cooking unit, and the cooking appliance includes a heat dissipation system, wherein the cooking unit is connected to the exhaust port 210 to exhaust internal steam.

[0052] The utility model improves the utilization rate of airflow in the lateral range of condensate box 200 to reach the effect that airflow is accelerated, the inlet efficiency of condensate box 200 is improved, the uniformity of cover plate 300 outlet air is improved, and the separation of airflow is also avoided. The vortex at the inlet of the sub-channel 102 is also reduced. Therefore, the overall flow of the system is improved, the uniformity of the airflow is improved, the air flow to the lower cooking equipment is reduced, and the heat dissipation performance and the dehumidification performance of the system are balanced and optimized.
