Description

Technical Field

[0001] This utility model relates to the technical field of condensation devices, and in particular to a steam condensation device and its cooking equipment. Background Technology

[0002] Cooking equipment, including but not limited to steam ovens or steam-grill combos, involves steam generated by a steam generator or bottom heating element entering the inner cavity of the cooking appliance to exchange heat with the food. The steam is then discharged directly from the appliance through a duct by a heat dissipation or condensation device. However, existing steam stays in the condensation device for a short time, resulting in a short heat exchange (condensation) time before being discharged by the fan. For example, an electric steamer with a condensation structure disclosed in Chinese Patent (Application Publication No. CN206761364U) has a high temperature when discharged from the appliance due to the short heat exchange (condensation) time, which can easily cause burns and poses a safety hazard. Furthermore, the large amount of steam discharged can cause dampness in the room, which can easily lead to bacterial growth. Therefore, improvements to existing steam condensation devices are needed. Summary of the Invention

[0003] The purpose of this invention is to provide a steam condensation device and its cooking equipment. By setting a baffle in the condensation box, the direction of the steam flow channel can be changed and the residence time of the steam in the flow channel can be extended, which can ensure that the steam can fully exchange heat in the flow channel, thereby effectively reducing the temperature and amount of steam when the steam is discharged from the steam oven.

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] like Figures 1-9As shown, a steam condensation device includes a cooling chamber 10, a condensation box 20, and a fan 30, which constitute the basic structure of the steam condensation device. The cooling chamber 10 is provided with an air inlet 11, an air outlet 12, and an air duct 13 connecting the air inlet 11 and the air outlet 12. Specifically, the diameter of the air duct 13 decreases from the air inlet 11 to the air outlet 22. The condensation box 20 is provided with a sealed chamber, which is provided with an inlet 21, an outlet 22, and a flow channel 23 connecting the inlet 21 and the outlet 22. The inlet 21 of the sealed chamber is connected to the inner liner 60 through the connecting pipe 40, so that the steam in the inner liner 60 enters the sealed chamber through the connecting pipe 40. The sealed chamber is provided with several baffles 24 for extending the length of the flow channel 23. The steam in the flow channel 23 enters the air duct 13 through the outlet 22. The fan 30 is fixedly installed on one side of the air inlet 11 of the cooling chamber 10. The steam in the air duct 13 is discharged through the exhaust port 12 by the fan 30. The fan 30 is preferably a cross-flow fan 30.

[0031] In some embodiments, the number of baffles 24 is N, where N ≥ 2. Each baffle 24 has multiple through holes 241. The number of through holes 241 on the baffles 24 adjacent to the inlet 21 increases from one side of the inlet 21 to the other side. The through holes 241 on adjacent baffles 24 are arranged alternately in opposite directions. By arranging the number of through holes 241 on the baffles 24, the direction of the steam flow channel 23 can be effectively changed, and the residence time of steam in the flow channel 23 can be extended. Furthermore, it can avoid the problem of steam being unable to withstand atmospheric pressure when flowing in a single direction.

[0032] Specifically, when N equals 2, the partition 24 includes a first partition 242 and a second partition 243. The first partition 242 is disposed on the side adjacent to the inlet 21, and the second partition 243 is disposed on the side adjacent to the outlet 22. The through holes 241 on the first partition 242 increase from the side of the inlet 21 to the other side of the inlet 21 along the length direction of the first partition 242, and the through holes 241 on the second partition 243 decrease from the side of the inlet 21 to the other side of the inlet 21 along the length direction of the second partition 243.

[0033] Specifically, when N equals 3, the partition 24 includes a first partition 242, a second partition 243, and a third partition 244 that are spaced apart from the inlet 21 to the outlet 22. The through holes 241 on the first partition 242 increase from one side of the inlet 21 to the other side along the length of the first partition 242. The through holes 241 on the second partition 243 decrease from one side of the inlet 21 to the other side along the length of the second partition 243. The through holes 241 on the third partition 244 increase from one side of the inlet 21 to the other side along the length of the third partition 244.

[0034] Specifically, the first partition 242, the second partition 243, and the third partition 244 are all the same partition 24, but their installation directions are different. The end of the first partition 242 with fewer through holes 241 is located on the side of the inlet 21, and the end of the first partition 242 with more through holes 241 is located on the side away from the inlet 21. The installation direction of the second partition 243 is opposite to that of the first partition 242, and the installation direction of the third partition 244 is opposite to that of the second partition 243. That is to say, the installation direction of the third partition 244 is the same as that of the first partition 242. When there is a fourth partition, the installation direction of the fourth partition is opposite to that of the third partition 244.

[0035] In some embodiments, the condenser box 20 includes a box body 25 with an opening at the top and a cover plate 26 that is detachably sealed to the box body 25. The side end of the box body 25 is provided with a slot 251 corresponding to the partition plate 24. The partition plate 24 is inserted into the slot 251. With the above arrangement, the partition plate 24 can be easily disassembled and assembled, so as to facilitate the cleaning of the partition plate 24.

[0036] In some embodiments, the housing 25 is integrally formed into the cooling chamber 10, specifically by integral injection molding, which reduces assembly time and assembly costs. A gap is left between the bottom of the housing 25 and the bottom of the air duct 13. The outlet 22 of the housing 25 is set downwards. The downward setting of the outlet 22 of the housing 25 facilitates the fan 30 to pump the cooled steam to the exhaust port 12.

[0037] In some embodiments, the enclosure 25 is provided with connecting posts 252 around its perimeter, and the cover plate 26 is fixedly connected to the connecting posts 252 by fasteners. The enclosure 25 is provided with a sealing ring 253 on the outer periphery corresponding to the sealed chamber. After the cover plate 26 is connected to the enclosure 25, the cover plate 26 and the enclosure 25 are sealed by the sealing ring 253. Through the above arrangement, it is prevented that the steam in the sealed chamber will not be sufficiently cooled before flowing out from the gap between the enclosure 25 and the cover plate 26.

[0038] In some embodiments, the number of outlets 22 is provided in multiples and arranged at intervals along the length of the housing 25. By increasing the number of outlets 22, the steam discharge rate can be effectively increased.

[0039] In some embodiments, the number of partitions 24 is N, where N≥2. Each partition 24 is provided with a flow port 245 between it and the side of the condenser box 20. The flow ports 245 of adjacent partitions 24 are alternately arranged. The flow port 245 of the partition 24 adjacent to the inlet 21 is arranged on the other side of the inlet 21. In this embodiment, the partitions 24 can be arranged horizontally or inclined. If they are inclined, the inclination direction and inclination angle of the multiple partitions 24 are the same.

[0040] A cooking appliance includes a main body 50, an inner pot 60, a water tank, and a steam generator. The inner pot 60 is fixedly disposed within the main body 50. The steam generator is a steam generator and / or an evaporation plate disposed at the bottom of the inner pot 60. The cooking appliance also includes a steam condensation device as described in any of the above. That is, the steam generator can be either a steam generator or an evaporation plate, or it can include both a steam generator and an evaporation plate.

[0041] The steam condensation device and cooking equipment of this utility model have a baffle 24 installed in the condensation box 20, which can change the direction of the steam flow channel 23 and prolong the residence time of the steam in the flow channel 23, thus ensuring that the steam can fully exchange heat in the flow channel 23, thereby effectively reducing the temperature and amount of steam when the steam is discharged from the steam oven.

[0042] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
