Another function of the channel is that: when cooling water flows through the channel, the inner container is cooled, so that water vapor in the inner container is condensed; when the oven works to bake food, the condensing assembly does not work, cooling water does not exist in the channel, gas does not flow, the channel can well keep the temperature of the inner container, and the working efficiency of the oven is improved.

The inside of the channel is provided with a plurality of pieces which extend from top to bottom and are arranged at intervals, so that the heat dissipation and heat preservation effects of the channel are further improved.

In order to further improve the heat dissipation effect, the channels and/or the sheet members are made of heat conducting materials, so that even if cooling water does not directly contact the inner container, the cooling rate of the inner container is not affected. And the heat conduction material can be used for rapidly conducting out the heat in the inner container, so that the condensation rate of steam is accelerated.

In order to further improve the heat dissipation effect, the upper end opening of the channel is the water inlet, and a water outlet pipe is arranged above the opening of the channel, and the water inlet of the water outlet pipe is communicated with the water outlet end of the water pump. The cooling water is sprayed onto the outer wall of the inner container or the inner side wall of the channel through the water outlet pipe, so that the flow speed is high and the heat dissipation effect is good.

In order to further improve the cooling rate of the liner, the second water outlets of the water outlet pipe are at least two and are axially arranged on the side wall of the water outlet pipe at intervals, and face the outer wall of the liner or the side wall of a channel clung to the outer wall of the liner, water is sprayed toward the outer wall of the liner in a directional manner, the heat dissipation effect is good, and a plurality of second water outlets spray water at the same time, so that water flows at different parts of the liner pass through, and the cooling rate is improved.

Because scale and the like are easy to remain in the water storage device after long-time use, the water storage device can be detachably arranged in the cavity in order to facilitate cleaning of the water storage device.

In order to facilitate the disassembly of the water storage device, a notch is formed in the shell, and the water storage device can be pulled by external force to pass through the notch to be separated from the oven or pushed by external force to pass through the notch to be installed in the cavity. The disassembling mode is simple, and only the water storage tank needs to be pulled. The detachable structure is not limited to the above-described structure, and may be other structure that can separate the water storage device from the oven, such as a structure in which the water storage device is engaged with the oven, but in view of the limited space of the oven interior chamber, a structure in which the water storage device is pulled out of the oven is preferable.

If the water storage device is of an integrated structure, the whole volume and the weight are large, so that the assembly is inconvenient, and the miniaturization of the oven is not facilitated. The water storage device comprises a water storage tank and a water collecting tank arranged above the water storage tank, wherein the water collecting tank is communicated with the lower end of the channel, a water outlet is formed in the position, corresponding to the water storage tank, of the water collecting tank, and the water storage tank can be pulled by external force to penetrate through the gap to separate from the oven or pushed by external force to penetrate through the gap to be installed in the cavity. Therefore, when the water pump does not work, water flow is almost completely positioned in the water storage tank, and only the water storage tank is required to be cleaned, so that the water storage tank is convenient to assemble and disassemble and the cooling water is convenient to replace.

In order to further facilitate the assembly and disassembly of the water storage tank, the water inlet end of the water pump is communicated with the water storage tank through a water inlet pipe, and at least the section of the water inlet pipe inserted into the water storage tank can be bent. The water pump is positioned outside the water storage tank, and when the water storage tank is pulled, the water pump is not required to be pulled at the same time, so that the pulling weight is reduced.

As shown in fig. 3 to 5, the condensation assembly 4 includes a water storage device, a water pump 42 and a channel 45, in this embodiment, the water storage device includes a water storage tank 41 and a water collecting tank 44, the water storage tank 41 is disposed adjacent to the bottom of the liner 2, the water collecting tank 44 is located above the water storage tank 41, a water outlet hole 441 is disposed at a position of the water collecting tank 44 corresponding to the water storage tank 41, and cooling water in the water collecting tank 44 flows into the water storage tank 41 through the water outlet hole 441. Of course, the water storage tank 41 and the water collection tank 44 may be formed as a single piece.

As shown in fig. 5 and 6, the channel 45 is a hollow box, the side wall of the box is attached to the outer wall of the liner 2, the box extends from top to bottom, the upper end of the channel 45 is provided with a water inlet 452, and the lower end of the channel is provided with a first water outlet 453 and is communicated with the water collecting tank 44. The channel 45 is further provided with a plurality of pieces 451 extending from top to bottom and arranged at intervals, and the channel 45 and the pieces 451 are made of heat conducting materials, such as aluminum or copper.

The channel 45 may be a hollow pipe, or a groove with one open surface is arranged on the outer side of the inner container 2, and the groove is matched with the outer wall of the inner container 2 through the opening to form the channel 45.

The water inlet end of the water pump 42 is communicated with the water storage tank 41 through a water inlet pipe 47, and the water outlet end of the water pump 42 is connected with the water inlet end of the water outlet pipe 43. The water outlet pipe 43 is arranged above the water inlet 452 of the channel 45, and a plurality of second water outlets 431 of the water outlet pipe 43 are axially arranged on the side wall of the water outlet pipe 43 at intervals and face the inner side wall of the channel 45 clung to the outer wall of the liner 2. The cooling water sprayed onto the outer wall of the liner 2 by the water outlet pipe 43 flows into the water storage tank 41 from top to bottom through the channel 45 and the water collecting tank 44 under the action of gravity. Namely, the water storage tank 41, the water inlet pipe 47, the water pump 42, the water outlet pipe 43 and the water collecting tank 44 form a circulating waterway system.

The water inlet pipe 47 and the water outlet pipe 43 are fixed on the inner container 2 through the buckling seat 431.

After the steam in the inner container 2 is condensed into condensed water, the condensed water is easy to drop to the ground when the oven door 6 is opened, thereby polluting the ground and reducing the comfort of the user. Therefore, as shown in fig. 7, the side wall of the liner 2 is provided with a perforation 21 for the condensed water in the liner 2 to flow into the water collecting tank 44, the perforation 21 is positioned above the water collecting tank 44 and inclines downwards from inside to outside, and the structure not only solves the problem of condensed water dripping, but also enables the condensed water to be recycled.

However, the arrangement of the through holes 21 easily causes the heat in the oven to flow out from the through holes 21 to lower the heating efficiency of the oven, so that a heat preservation head 46 for heat preservation is arranged at the position of the outer wall of the inner container 2 corresponding to the through holes 21, and a water outlet groove 461 for enabling condensed water to flow into the water collecting groove 44 is arranged on the heat preservation head 46. When the oven is used for baking food, the heat preservation head 46 is blocked at the perforation 21, so that the heat loss in the inner container 2 can be reduced. When the oven is not in operation, the steam in the liner 2 is condensed under the action of the condensing assembly 4 and then flows into the water collecting tank 44 through the perforation 21 and the heat preservation head 46 in sequence.

After long-term use, scale, impurities and the like are easy to remain in the water storage tank 41, and the water storage tank 41 can be detachably arranged in the cavity 3 in order to facilitate the cleaning of the water storage tank 41. In this embodiment, a notch 11 is formed in the housing 1 of the oven, the notch 11 is disposed towards one side of the oven door 6, and when the oven door 6 is opened, the water storage tank 41 can be pulled out of the notch 11 to separate from the oven, or pushed back through the notch 11 and installed in the chamber 3. Because one end of the water inlet pipe 47 is connected to the water storage tank 41, at least the section of the water inlet pipe 47 inserted into the water storage tank 41 needs to be provided with a flexible pipe capable of being bent, so as to avoid interference of the water inlet pipe 47 to the water storage tank 41 when the water storage tank 41 is pulled. Of course, the water inlet pipe 47 may also be designed as a hose as a whole.

However, after the water storage tank 41 is disassembled, it is difficult to precisely push the water storage tank 41 back to the original position when the water storage tank 41 is reassembled, so that the cooperation of the water storage tank 41 with other components is affected. Therefore, a positioning mechanism for positioning the water storage tank 41 is arranged between the water storage tank 41 and the water collecting tank 44 in a matching way, and the positioning mechanism comprises a clamping protrusion 49 arranged on the water storage tank 41 and a clamping groove 50 arranged on the water collecting tank 44, wherein the clamping protrusion 49 can be separated from the clamping groove 50 along with the water storage tank 41 under the pulling of external force or correspondingly clamped in the clamping groove 50 under the pushing of external force, so that the water storage tank 41 can be ensured to be installed in place and can be prevented from loosening.

In order to facilitate pulling of the water storage tank 41, a handle 412 is arranged on one side of the water storage tank 41 facing the notch 11, and a flange for increasing friction force is arranged on the peripheral wall of the handle 412.

In order to prevent the cooling water remaining in the water collection tank 44 from dripping into the chamber 3 after the water storage tank 41 is removed. The chamber 3 is provided with a first bracket 411, and the water storage tank 41 is movably arranged on the first bracket 411.

An elastic piece 48 which enables the free end of the water collecting tank 44 to move upwards is arranged between the water storage tank 41 and the water collecting tank 44 in a matching way, one end of the elastic piece 48 is fixed at the bottom of the water collecting tank 44, the other end of the elastic piece is fixed on the first bracket 411 and is in a U-shaped fork structure, and the end part of the water storage tank 41 is clamped in a fork groove 481 of the U-shaped fork.

When the water storage tank 41 is taken out, the clamping convex 49 is separated from the clamping groove 50, the water storage tank 41 is separated from the fork groove of the U-shaped fork, and the free end of the water collection groove 44 moves upwards under the action of the elastic piece 48, so that water in the water collection groove 44 is far away from the water outlet 441, and water dripping is avoided.

Another function of the positioning mechanism is to move the free end of the sump 44 downward for return. Since the card slot 50 in the present embodiment is L-shaped, the card protrusion 49 extends toward the card slot 50, and the end surface of the card protrusion 49 facing the card slot 50 is inclined from top to bottom to form a pressing surface 491 for pressing the card slot 50 downward, and the pressing surface 491 is inclined away from the card slot 50, and the bottom of the card slot 50 is located below the top end of the pressing surface 491 and above the bottom of the pressing surface 491. When the water storage tank 41 is installed, the clamping protrusion 49 is inserted into the clamping groove 50, and the pressing surface 491 continuously presses the clamping groove 50 to gradually move the water collection tank 44 downwards for resetting until the water collection tank 44 is in a horizontal state or a state that the free end of the water collection tank 44 is slightly inclined downwards, so that water in the water collection tank 44 smoothly flows into the water storage tank 41.

The air blower 5 is disposed above the water outlet pipe 43, and an air outlet of the air blower 5 is disposed towards the water inlet of the channel 45, so that cold air of the air blower 5 is fully blown into the channel 45. When the steam condenser is used, the blowing device 5 or the condensing assembly 4 can be independently started, or the blowing device 5 and the condensing assembly 4 can work simultaneously, so that the condensation rate of steam in the liner 2 is accelerated. The blowing device 5 of this embodiment can blow cold wind and make the steam condensation of inner bag 2, for the mode that current at the oven gate formed the air curtain, safer and more reliable because the air curtain can not shelter from steam in the oven completely.

For ease of installation and for rapid condensation of the vapour in the liner 2, the condensation assembly 4 and the blowing device 5 are preferably arranged in the chamber 3 between the side wall of the liner 2 having a larger area and the housing 1.
