DETAILED DESCRIPTION

[0028] The following examples are used to illustrate the present application, but the present application is not limited by these examples. Modifications or equivalent replacements to the specific embodiments of the present application or to some technical features without departing from the spirit of the present application should be covered in the technical solution range claimed by the present application.

[0029] Example 1

[0030] Reference Figures 1-5 The present embodiment provides a condensation and exhaust system, which comprises an exhaust assembly 1, a condensation assembly 2 and a fan assembly 3. The exhaust assembly 1 is provided with a downwardly open exhaust passage 121 and a condensation cavity 13 located at the rear end of the exhaust passage 121. At least one exhaust hole group is formed in the bottom or front side cavity wall of the condensation cavity 13. The exhaust hole group comprises sub-exhaust holes 1241 arranged at intervals along the left and right sides. The condensation cavity 13 is in communication with the exhaust passage 121 through the exhaust hole group. Air inlets 123 are formed in the left and / or right side walls of the exhaust assembly 1. In this embodiment, air inlets 123 are formed in the left and right side walls at the rear end of the exhaust assembly 1 to increase the unit air inlet area. The condensation assembly 2 is arranged in the condensation cavity 13 and has a condensation passage 211. At least one air outlet hole group is formed in the outer side wall of the condensation assembly 2. The opposite ends of the condensation passage 211 are respectively in communication with the two air inlets 123. The condensation passage 211 is in communication with the condensation cavity 13 through the air outlet hole group. The fan assembly 3 is arranged behind the exhaust assembly 1, and the air outlet of the fan assembly 3 is in communication with the exhaust passage 121.

[0031] When high-temperature gas flows into the condensation passage 211 of the condensation assembly 2 from the air inlets 123, it is discharged from the multiple sub-air outlets 212 into the condensation cavity 122, and then flows into the exhaust passage 121 through the air outlet hole group, and finally is discharged from the front end of the exhaust passage 121. In this process, the high-temperature gas is dispersed multiple times, which can effectively reduce the temperature of the high-temperature gas discharged from the exhaust passage 121 of the exhaust assembly 1, avoid scalding of the discharged high-temperature gas, and reduce the problem of water droplets hanging at the outlet of the exhaust air duct 121.

[0032] Reference Figures 2-5 In the present embodiment, the air outlet hole groups are arranged on both the front and rear outer side walls of the condensing assembly 2, and each air outlet hole group comprises a plurality of sub-air outlet holes 212 arranged in the front-rear direction. In this way, the sub-air outlet holes 212 are arranged on the front or rear outer side wall of the condensing assembly 2. The air outlet hole groups are arranged on the bottom of the condensing cavity 13, and each air outlet hole group comprises a plurality of sub-air outlet holes 1241 arranged in the left-right direction. The sub-air outlet holes 1241 are arranged vertically to the sub-air outlet holes 212. As can be seen, the sub-air outlet holes 212 of the condensing assembly 2 are arranged vertically to the sub-air outlet holes 1241 on the bottom of the condensing cavity 13. In this way, the high-temperature gas flowing out of the sub-air outlet holes 212 needs to bend to enter the sub-air outlet holes 1241 of the condensing cavity 13, thereby prolonging the travel distance of the exhaust gas and improving the cooling effect.

[0033] Reference Figure 5 More specifically, a flange 1242 extending downward into the exhaust passage 121 is fixed to the rear edge of the sub-air outlet hole 1241. The flange 1242 is located in the air outlet direction of the fan assembly 3 and is located rearward of the air outlet direction of the sub-air outlet hole 1241. In this way, the gas flowing out of the sub-air outlet hole 1241 can only flow forward along the exhaust passage 121, and at the same time, the gas exhausted from the condensing cavity 13 is dispersed.

[0034] Reference Figures 1-5 Further, a plurality of heat dissipation holes 125 are arranged in the left-right direction on the rear side wall of the condensing cavity 13. The air outlet of the fan assembly 3 communicates with the condensing cavity 13 through the heat dissipation holes 125. In this way, the cold air continuously enters the condensing cavity 13 through the heat dissipation holes 125 under the action of the fan assembly 3, and then exchanges heat with the condensing assembly 2. The high-temperature gas in or flowing out of the condensing assembly 2 is rapidly cooled, achieving a secondary cooling effect. Specifically, the heat dissipation holes 125 are arranged in parallel and staggered with the sub-air outlet holes 212. In this way, the cold air of the fan assembly 3 can cool and heat the condensing assembly 2, and at the same time, the interference between the cold air flowing in from the heat dissipation holes 125 and the high-temperature gas exhausted from the condensing assembly 2 is reduced.

[0035] Reference Figures 2-5 Further, a plurality of support portions 126 extending upward and arranged in the left-right direction are arranged in the condensing cavity 13. The condensing assembly 2 is installed on the plurality of support portions 126, and a gap is left between the condensing assembly 2 and the bottom of the condensing cavity 13. In this way, the strength of the exhaust assembly 1 itself is enhanced, and reliable support of the condensing assembly 2 is achieved, and at the same time, the travel distance of the exhaust gas is prolonged. In addition, a plurality of turbulence portions 127 are arranged in the exhaust passage 121. The plurality of turbulence portions 127 are arranged irregularly. In this way, when the high-temperature gas flows through the exhaust passage 121, it is again dispersed by the plurality of irregular turbulence portions 127 and is exhausted out of the exhaust assembly 1. This ensures that the exhausted high-temperature gas does not concentrate at a certain point and have a high temperature problem, further improving the cooling effect.

The cover plate 11 is detachably and sealingly connected with the exhaust cover 12 and covers the upward opening of the cavity 122, and the cover plate 11 and the cavity 122 form a condensation cavity 13, so that the condensation assembly 2 can be quickly disassembled.

[0037] Specifically, a plurality of support portions 126 and a plurality of fixing columns 128 are arranged on the exhaust cover 12 and located in the cavity 122, the support portions 126 are integrally formed with the exhaust cover 12 and are used for strengthening the strength of the exhaust cover and reliably supporting the condensation assembly, a profiling positioning groove (not shown in the figure) which is the same as the outer contour of the condensation assembly 2 is arranged on the support portion 126, and the condensation assembly 2 is transversely arranged in the profiling positioning groove.

In addition, a plurality of turbulence portions 127 which are irregularly arranged are integrally formed on the exhaust cover 12 and located in the exhaust passage 121.

[0038] Reference Figures 2-4 The condensation assembly 2 comprises a condensation pipe 21 which is arranged in the condensation cavity 13 and connected with the air inlet interface 123, a condensation passage 211 which communicates with the air inlet interface 123 is formed in the inside of the condensation pipe 21, and a group of air outlet holes are arranged on the outside wall of the condensation pipe 21. In this embodiment, the condensation pipe 21 is made of stainless steel metal material, a group of air outlet holes are arranged on the front and rear outside walls of the condensation pipe 21, the air outlet directions of the air outlet holes are arranged vertically to the air outlet directions of the exhaust hole group at the bottom of the condensation cavity 13, so as to increase the unit air outlet area, facilitate the dispersion of high-temperature gas, and lengthen the exhaust path.

The evaporator 51 is arranged outside the inner container assembly 4, and a steam outlet of the evaporator 51 is connected with the cooking cavity 41 through a gas connection pipe 52, so as to provide high-temperature steam required for cooking for the inner container assembly 4. The condensation exhaust system is arranged on the top of the inner container assembly 4 through a partition plate 43, and the exhaust port 42 of the inner container assembly 4 is connected with an air inlet interface 123 through the gas pipe assembly, so as to facilitate the high-temperature gas in the inner container assembly to be exhausted through the condensation exhaust system, to achieve the purpose of less steam when the cooking equipment is opened, and meanwhile, the temperature of the high-temperature gas exhausted from the inner container assembly 4 can be effectively reduced, so as to avoid the high-temperature gas from scalding people.
