However, adding a cooling structure is costly on the one hand, and on the other hand it will greatly encroach on the internal space of the equipment, which is not conducive to the miniaturization of the equipment. Utility Model Content

The steam pipe passes through the cooling water box, and its two ends are respectively connected to the inner tank and the exhaust assembly.

[0007] In one embodiment, the cooling water box is located on the top of the inner tank.

[0008] In one embodiment, the steam pipe includes a condensation return pipe and an exhaust pipe that are interconnected.

The bottom end of the condensation return pipe is connected with the inner tank, and the condensation return pipe extends upward through the side of the cooling water box to connect with the top of the exhaust pipe.

[0009] In one embodiment, the portion of the condensation return pipe located inside the cooling water box is S-shaped.

[0010] In one embodiment, the bottom surface of the cooling water box is in contact with the air guide plate of the exhaust assembly.

[0011] In one embodiment, the bottom surface shape of the cooling water box corresponds to the shape of the air guide plate.

[0012] In one embodiment, the cooling assembly further includes a water level sensor disposed on the cooling water box, and the water level sensor is electrically connected to the water inlet pump on the water inlet pipe.

[0013] In one embodiment, the water inlet pipe is connected to the side of the cooling water box close to the top surface, and the water outlet pipe is connected to the side of the cooling water box close to the bottom surface.

[0014] In one embodiment, the cooling water box is made of aluminum alloy.

[0015] A second aspect of the present application is a multifunctional cooking device comprising the above-mentioned exhaust cooling structure.

[0016] The exhaust steam cooling structure connects the cooling water box with the inner pot through a water outlet pipe, so that the cooling water box can, on the one hand, function as a normal water tank to provide the water required for the steaming function of the cooking equipment; on the other hand, the steam pipe runs through the cooling water box, and the high-temperature steam can be cooled by the cooling water box in a wrapped water bath, effectively reducing the temperature of the exhaust steam.

[0027] Please combine Figure 1 as well as Figure 2 As shown, the present application first provides an exhaust cooling structure, including an inner liner 10, a steam pipe 20, an exhaust assembly 30 and a cooling assembly 40; the cooling assembly 40 includes a water inlet pipe 41, a cooling water box 42 and a water outlet pipe 43 connected in sequence, the other end of the water outlet pipe 43 is connected to the inner liner 10, the exhaust assembly 30 and the cooling water box 42 are both fixed relative to the inner liner 10, the steam pipe 20 passes through the cooling water box 42, and the two ends are respectively connected to the inner liner 10 and the exhaust assembly 30.

[0028] In this application, the cooling water box 42 is connected to the inner tank 10 through the water outlet pipe 43. The cooling water box 42 contains cooling water, so that the cooling water box 42 can play the role of a normal water tank on the one hand, providing the cooking equipment with the moisture required for the steaming function. On the other hand, the steam pipe 20 runs through the cooling water box 42, and the high-temperature steam can be wrapped in a water bath through the cooling water box 42, effectively reducing the temperature of the exhaust steam.

[0029] In addition, the other end of the steam pipe 20 is connected to the exhaust component 30. When the exhaust component 30 is working, it can assist in the exhaust of steam and play an air cooling role to further reduce the temperature of the exhaust steam.

[0030] Specifically, the space occupied by the cooling water box 42 in the present application is close to the space occupied by the water tank in ordinary cooking equipment with steaming function, and there is no need to add an additional cooler. It can effectively reduce the exhaust steam temperature while effectively controlling the equipment cost and overall volume.

[0031] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, the cooling water box 42 is located at the top of the inner tank 10, so that after the steam in the steam pipe 20 is condensed through the cooling water box 42, the condensed water can flow back into the inner tank 10 along the steam pipe 20. On the one hand, it can reduce the water consumption of the steaming function and increase the endurance of the steaming function. On the other hand, the steam condensation can also reduce the amount of steam discharged, reducing the possibility of the discharged steam scalding the user.

[0032] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, the steam pipe 20 includes a condensation return pipe 21 and an exhaust pipe 22 that are interconnected. The exhaust pipe 22 is located in the cooling water box 42 and passes through the bottom surface of the cooling water box 42 in a vertical direction to connect with the exhaust assembly 30. The bottom end of the condensation return pipe 21 is connected with the inner tank 10, and the condensation return pipe 21 extends upward through the side of the cooling water box 42 to connect with the top of the exhaust pipe 22.

[0033] Preferably, the portion of the condensation return pipe 21 located in the cooling water box 42 is tilted and S-shaped to increase the contact area between the condensation return pipe 21 and the cooling water in the cooling water box 42, thereby improving the water bath cooling effect and also facilitating the steam to condense and return to the inner tank 10.

[0034] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, the bottom surface of the cooling water box 42 is in contact with the air guide plate 31 of the exhaust assembly 30 .

[0035] Due to the operation of the exhaust assembly 30, there is always a low-temperature airflow passing through the air guide plate 31. By fitting the air guide plate 31 with the cooling water box 42, the heat accumulated in the cooling water in the cooling water box 42 can be taken away through the air guide plate 31, thereby avoiding the cooling effect of the water bath being affected by the high temperature of the cooling water.

[0036] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, the bottom shape of the cooling water box 42 corresponds to the shape of the air guide plate 31.

[0037] Of course, in some other embodiments, the cooling water box 42 may also be of other shapes, as long as it fits with the air guide plate 31 and can perform heat exchange with the air guide plate 31 to achieve cooling.

[0038] Preferably, the cooling water box 42 is made of aluminum alloy to improve the heat exchange efficiency between the cooling water box 42 and the air guide plate 31 .

[0039] Of course, the cooling water box 42 may also be made of other materials with better thermal conductivity, and this application will not give examples one by one here.

[0040] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, the cooling assembly 40 further includes a water level sensor 44 disposed in the cooling water box 42 , and the water level sensor 44 is electrically connected to the water inlet pump 41 a on the water inlet pipe 41 .

[0041] The water level sensor 44 is used to detect the cooling water level in the cooling water box 42. When it is detected that the water level is not full, the water inlet pump 41a is controlled to start and pump water from an external water source into the cooling water box 42 to ensure that the cooling water box 42 is always full of cooling water, thereby ensuring the water bath cooling effect on the steam pipe 20.

[0042] In some embodiments, a solenoid valve 43a is provided on the water outlet pipe 43. When the inner tank 10 needs water, the solenoid valve 43a opens, and the cooling water in the cooling water box 42 enters the inner tank 10 through the water outlet pipe 43. The water level sensor 44 detects the water level drop and controls the water inlet pump 41a to work to maintain the water level in the cooling water box 42. The cycle is repeated so that the cooling water box 42 can take into account the functions of both water tank and water bath cooling to ensure the condensation effect.

[0043] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, the water inlet pipe 41 is connected to the side of the cooling water box 42 close to the top surface, and the water outlet pipe 43 is connected to the side of the cooling water box 42 close to the bottom surface.

[0044] It is easy to understand that the temperature of the cooling water entering the cooling water box 42 through the water inlet pipe 41 is relatively low, while the temperature of the cooling water discharged through the water outlet pipe 43 after being cooled in the water bath and absorbing the heat of the steam is relatively high. Therefore, by connecting the water inlet pipe 41 to the side of the cooling water box 42 near the top surface and the water outlet pipe 43 to the side of the cooling water box 42 near the bottom surface, the temperature of the upper layer of cooling water in the cooling water box 42 can be made lower than that of the lower layer;

[0045] The condensation return pipe 21 penetrates from the bottom side of the cooling water box 42 to the inside of the cooling water box 42 and extends upward at an angle, so that the steam in the condensation return pipe 21 can be fully condensed to maximize the condensation reflux efficiency.

[0046] A second aspect of the present application is a multifunctional cooking device comprising the above-mentioned exhaust cooling structure.

[0047] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
