[0038] The utility model provides a kind of implementation of condensing device, referring to Figure 1 And 2It includes a base, within which a cooling chamber is provided. A condenser is installed within the cooling chamber, dividing the cooling chamber into a first chamber 2 for cooling water vapor and a second chamber 3 for cooling oil fumes. Figure 1 As shown in the diagram, in this embodiment, the first cavity 2 is the cavity located below the condenser, and the second cavity 3 is the cavity located above the condenser. When the direction of the condenser 1 changes, the orientation of the first cavity 2 and the second cavity 3 will also change adaptively. A switching structure is also provided on the base, which includes an outer valve body 4 with a cavity and an inner valve body 5 with a cavity. The outer valve body 4 is sleeved on the inner valve body 5 and is horizontally arranged. The side walls of the outer valve body 4 and the inner valve body 5 are respectively provided with... At least one first vent 6 is provided, and at least one second vent 7 is also provided on the side wall of the outer valve body 4 and the side wall of the inner valve body 5. In this embodiment, the number of first vent 6 on the outer valve body 4 and the number of first vent 6 on the inner valve body 5 are two each. The two first vent 6 on the same component are arranged at intervals along the axial direction of the component. The number of second vent 7 on the outer valve body 4 and the number of second vent 7 on the inner valve body 5 are also two each. The two second vent 7 on the same component are arranged at intervals along the axial direction of the component. This facilitates the effective ensuring that the first vent 6 on the outer valve body 4 is opposite to the first vent 6 on the inner valve body 5 and the second vent 7 on the outer valve body 4 is opposite to the second vent 7 on the inner valve body 5 when the inner valve body 5 or the outer valve body 4 moves linearly. The condensing device 1 also includes a drive mechanism 8 for driving the outer valve body 4 or the inner valve body 5 to move linearly. The drive mechanism 8 can be a wax motor or a linear motor or other mechanism capable of linear movement. In the first state, the first vent on the outer valve body 4... Hole 6 coincides with the first air outlet 6 on the inner valve body 5 ("coincidence" can be understood as complete coincidence or partial coincidence; as long as there is an overlap, the first air outlet 6 on the outer valve body 4 and the first air outlet 6 on the inner valve body 5 can be connected), and the first air outlet 6 is connected to the first cavity 2. Meanwhile, the second air outlet 7 on the outer valve body 4 and the second air outlet 7 on the inner valve body 5 are misaligned, thus ensuring that the cavity of the inner valve body 5 is connected to the first cavity 2. At this time, the steam oven is in steam-operated mode. See [link / reference]. Figure 6-1, water vapor from the cavity of the inner valve body 5 enters the first cavity 2 of the cooling cavity through the first air outlet hole 6 on the inner valve body 5 and the outer valve body 4, and the gas flowing out after being cooled by the condensing member is blown out of the condensing device 1 by the air supply member 9. The cooled gas will not scald the user, and part of the condensed liquid water will flow into the liquid recovery box. In the second state, the second air outlet hole 7 on the outer valve body 4 coincides with the second air outlet hole 7 on the inner valve body 5 (the so-called "coincidence" can be understood as complete coincidence, or partial coincidence, as long as there is a coincident part, that is, the second air outlet hole 7 on the outer valve body 4 and the second air outlet hole 7 on the inner valve body 5 are in communication), and the second air outlet hole 7 is in communication with the second cavity 3, while the first air outlet hole 6 on the outer valve body 4 is misaligned with the first air outlet hole 6 on the inner valve body 5, thereby ensuring that the cavity of the inner valve body 5 is in communication with the second cavity 3. At this time, the steaming oven is in a mode of working without steam. See Figure 6-2 At this time, only oil fume is generated, which enters the second cavity 3 of the cooling cavity through the second air outlet hole 7 on the inner valve body 5 and the outer valve body 4, and the smoke flowing out after being cooled by the condensing member is blown out of the condensing device 1 by the air supply member 9. The cooled smoke will not scald the user. Because the gas generated in the mode with steam and the gas generated in the mode without steam are cooled separately, the recovered liquid water is clean and oil-free and can be reused, avoiding food odor.

Since the driving mechanism 8 driving the inner valve body 5 or the outer valve body 4 to move is linear motion, the movement stroke of the driving mechanism 8 is determined, and the positions of the first gas outlet hole 6 on the inner valve body 5 and the outer valve body 4 and the positions of the second gas outlet hole 7 on the inner valve body 5 and the outer valve body 4 can be accurately set, so that the coincidence of the first gas outlet hole 6 on the inner valve body 5 and the outer valve body 4 and the dislocation of the second gas outlet hole 7 can be ensured, and the coincidence of the second gas outlet hole 7 and the dislocation of the first gas outlet hole 6 can be ensured, the structure is simple, the control is accurate, the switching failure is avoided, and in addition, the air is communicated through the inner valve body 5, and the outer valve body 4 and the inner valve body 5 are horizontally arranged, so that one end of the conduit can be directly communicated with the air inlet of the inner valve body 5, and the other end is connected to the steaming oven body 10, so that the limitation that the air inlet can only be arranged at the top of the steaming oven body 10 is avoided, and the space for selecting the air inlet direction is larger.

Specifically, in the first state, the first air outlet hole 6 on the outer valve body 4 coincides with the first air outlet hole 6 on the inner valve body 5. The spring 13 can be in a compressed state or in a natural elongation state (i.e. an elastic reset state). In the compressed state, the driving mechanism 8 is actuated to drive the outer valve body 4 to move linearly and compress the spring 13. In the second state, in order to make the second air outlet hole 7 on the outer valve body 4 coincide with the second air outlet hole 7 on the inner valve body 5, the driving mechanism 8 is actively retracted or retracted after being powered off.

Conversely, the spring 13 can be in an elastic reset state in the first state and in a compressed state in the second state, which is set according to the actual situation. Through the action of the spring 13, not only the buffering effect of the movement of the outer valve body 4 can be provided, but also the action of driving the reset movement of the outer valve body 4 can be achieved.

Only the outer valve body 4 needs to be moved to switch the cavity of the inner valve body 5 between the communication with the first cavity 2 or the communication with the second cavity 3. The structure is simple and convenient to maintain. In this embodiment, the spring 13 can be sleeved on the outer side wall of the inner valve body 5.
