[0028] The technical scheme of the present application will be further described in detail below through specific embodiments and in conjunction with the drawings:
[0029] Embodiment 1
[0030] The present embodiment is a first embodiment of a steam oven capable of recycling condensate water, which combines the advantages of the prior art and overcomes the shortcomings of the prior art. Figures 1 to 4 As shown in the figure, it comprises a box body 1 provided with a steaming oven chamber 101, an electric heating tube 2 arranged in the steaming oven chamber 101, and a steam generator 4 connected to the box body 1, the outlet end of the steam generator 4 being in communication with the steaming oven chamber 101; further comprising a heating tube 3, the bottom of the steaming oven chamber 101 is provided with a water collecting groove 103, and the heating tube 3 is connected to the steaming oven chamber 101 and a part of the heating tube 3 is located in the water collecting groove 103.
[0031] In the prior art, the heating tube 3 is connected to the bottom of the steaming oven chamber 101, and since there is a large amount of condensate water accumulated at the bottom of the steaming oven chamber, a large number of sealing structures need to be provided to prevent the condensate water from leaking out through the installation position of the evaporation disc, which results in high cost and the sealing structures are also troublesome to install.
[0032] Further, the bottom of the steaming oven chamber 101 is provided with a first inclined surface 105, and the water collecting groove 103 is located on the first inclined surface 105, and the height of the place where the water collecting groove 103 is located is lower than the height of the edge of the first inclined surface 105. The first inclined surface 105 can guide the condensate water to flow into the water collecting groove 103, thereby increasing the amount of condensate water in the water collecting groove 103 and reducing the residual condensate water outside the water collecting groove 103.
[0033] Further, the inner edge of the water collecting groove 103 and the outer edge of the part of the heating tube 3 located in the water collecting groove 103 are equal in straight line distance, that is, the shape of the water collecting groove 103 and the part of the heating tube 3 located in the water collecting groove 103 are matched, which can increase the contact area between the heating tube 3 and the condensate water in the water collecting groove 103, thereby improving the evaporation efficiency of the condensate water.
[0034] Further, the two ends of the heating tube 3 are spaced apart from the bottom of the steaming oven chamber 101 in the vertical direction, and the two ends of the heating tube 3 are respectively rotatably connected to the opposite sides of the steaming oven chamber 101. By rotating the heating tube 3, the part of the heating tube 3 located in the water collecting groove 103 can be rotated to the outside of the water collecting groove 103, which facilitates the user to scrub the water collecting groove 103.
[0035] Further, it further comprises a temperature controller 13, and the temperature controller 13 is electrically connected to the heating tube 3. The temperature controller 13 can control the heating temperature of the heating tube 3, so as to heat the heating tube 3 to a set temperature when needed to assist the baking of food in the steaming oven chamber 101.
[0036] Furthermore, the steam oven 101 is equipped with three first baking tray rails 14 and three second baking tray rails 15. The first baking tray rails 14 are longitudinally distributed on one side of the steam oven 101, and the second baking tray rails 15 are longitudinally distributed on the other side of the steam oven 101. The first baking tray rails 14 and the second baking tray rails 15 are arranged opposite each other. It can be understood that the baking trays for placing food can be placed on the first baking tray rails 14 and the second baking tray rails 15. Setting multiple first baking tray rails 14 and multiple second baking tray rails 15 can support multiple layers of baking trays, thereby allowing more food to be baked at the same time.
[0037] The working principle or workflow of this embodiment is as follows: During implementation, the steam generator 4 supplies steam to the steam oven 101. When the steam encounters the inner wall of the steam oven 101, it condenses into water. The condensate flows along the inner wall of the steam oven 101 under its own weight to the water collection tank 103. The portion of the heating tube 3 located inside the water collection tank 103 can heat the condensate in the water collection tank 103, causing the water in the water collection tank 103 to evaporate and form steam. During the baking process of the food, the heat source is mainly the electric heating tube 2, with the heating tube 3 as a secondary source.
[0038] The beneficial effects of this embodiment:
[0039] 1. Install heating elements and a water collection tank. The heating elements can reach a higher heating temperature than the evaporation plate, thus assisting in heating the food in the steam oven.
[0040] 2. The heating element is rotated inside the steam oven, and rotating the heating element makes it easy to clean the water tank.

During the process of the steam generator 4 supplying steam to the steam oven 101, as the amount of steam in the steam oven 101 increases, the excess steam in the steam oven 101 can enter the condenser box 6 through the return pipe 5 and condense into water. The condensate in the condenser box 6 then flows back to the water collection tank 103 in the steam oven 101 through the return pipe 5. The return pipe 5 and the condenser box 6 can recover a portion of the steam discharged from the steam oven 101, thereby increasing the amount of condensate in the water collection tank 103 and reducing the amount of steam discharged from the steam oven 101.
[0043] Further, the condensing box is provided with a cavity 601, a water outlet 602 and a first air-permeable through hole 603; the cavity 601 is communicated with the inner cavity of the reflux pipe 5 through the water outlet 602, and the cavity 601 is communicated with the outside of the condensing box 6 through the first air-permeable through hole 603; the box body 1 is provided with an exhaust port 102 communicated with the steaming and baking chamber 101, the position of the exhaust port 102 is lower than that of the water outlet 602; one end of the reflux pipe 5 is connected with the exhaust port 102, and the other end is connected with the water outlet 602.

[0044] Further, the condensing box 6 is provided with a second inclined surface 604 in the cavity 601, and the water outlet 602 is located at the bottom end of the second inclined surface 604. The second inclined surface 604 can guide the condensed water to flow to the water outlet 602, thereby reducing the residue of the condensed water in the cavity 601.
[0045] Further, the cavity 601 is provided with a condensing baffle 7, and the condensing baffle 7 is located at the top end of the second inclined surface 604. Part of the steam in the cavity 601 can contact the condensing baffle 7 and condense into water on the surface of the condensing baffle 7, and then flow to the water outlet 602 along the second inclined surface 604. The setting of the condensing baffle 7 can improve the condensing efficiency of the steam.
[0046] The other features, working principles and beneficial effects of the embodiment are consistent with those of embodiment 1.
