Description

Technical Field

[0001] The utility model relates to the technical field of kitchen equipment, in particular to a steam condensing device and a steam box or a steam oven comprising the same. Background Art

[0002] A steamer or steam oven is a cooking device that heats water to form high-temperature steam, and then inputs the high-temperature steam into an inner pot to heat food. During this process, the high-temperature steam passes through the exhaust system of the steamer or steam oven and is discharged outside the steamer or steam oven, posing a risk of scalding.

[0003] In order to reduce the trouble caused to customers by the high-temperature steam discharged, steamers or steam ovens equipped with steam condensation structures have appeared on the market. Such structures include an upper condensation box and a second condensation box stacked on top of it. The upper condensation box is provided with a condensation tube for connecting with the inner tank to introduce steam. The other end of the condensation tube extends upward into the second condensation box. The high-temperature water vapor introduced into the condensation tube is cooled by an exhaust fan, and then passed upward into the second condensation box to be naturally cooled and turned into hot air. Finally, it returns to the upper condensation box and is discharged from the steamer or steam oven by the fan, which greatly improves the condensation effect. However, in this type of condensate upper discharge structure, the condensate is easily blocked in the condensation tube, making it difficult for the steam to be discharged smoothly for the natural cooling process, and abnormal noise will occur, and its actual use effect is poor. At the same time, the second condensation box located at the top has a higher sealing effect, and is prone to high-temperature steam leakage. Utility Model Content

[0029] The following is only a preferred implementation of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. At the same time, it should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0030] It should be noted that, in this document, relational terms such as first and second are merely used to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any actual relationship or order between these entities or operations.

[0031] The directional words mentioned in this embodiment, such as "up, down, left, right", etc., are only used in conjunction with the drawings to enable technicians in this technical field to understand the relationship between various features or parts.

[0032] like Figures 1 to 6 As shown, the steam condensing device of the utility model comprises an upper condensing box 1 and a lower condensing box 2 which are arranged in an overlapping manner. The overlapping may be arranged in a close fit and may leave a certain gap. In this embodiment, in order to save space and prevent air leakage, an inner and outer structure is adopted, that is, an outer condensing box is put on the outer side of the lower condensing box 2, and an upper condensing box 1 located above is formed between the lower condensing box 2 and the outer condensing box. Both the upper condensing box 1 and the lower condensing box 2 are flat rectangular structures with hollow inner cavities, and the whole body is welded with stainless steel material. An air inlet 3 and an air outlet 4 are respectively provided on the opposite side walls of the upper condensing box 1;

[0033] The upper condensation box 1 is provided with a condensation tube 5, wherein the condensation tube 5 is made of stainless steel or copper, one end of the condensation tube 5 horizontally extends to the outside of the upper condensation box 1 and forms a steam interface 6, the steam interface 6 is used to connect to the inner tank of the steam box or oven through a conduit, and the other end of the condensation tube 5 extends vertically downward to the lower condensation box 2 through a bent elbow;

[0034] The lower condensation box 2 is in a closed state, and is connected to the upper condensation box 1 via a steam exhaust port 7. The lower condensation box 2 is provided with a drain pipe 8 for discharging condensed water.

[0035] In order to enhance the condensation effect, a cold air fan 10 and an air duct 11 are also configured. The cold air fan 10 is arranged on one side of the air inlet 3 of the upper condensation box 1 and adopts a cross-flow fan. The cold air fan 10 is a fan used by the steamer or steam oven 2 in the prior art to discharge steam. The air duct 11 is arranged on one side of the air outlet 4 to guide the discharge of hot air.

[0036] During operation, the high-temperature water vapor in the inner tank of the steam box or steam oven will be introduced into the condenser tube 5. Under the action of the cold air blower 10, air will be blown to the upper condenser box 1 through the air inlet 7. The air inlet 3 will act on the condenser tube 5, so that the condenser tube 5 will be cooled to achieve primary condensation, and the high-temperature water vapor will be condensed once. Then, the other end of the condenser tube 5 will extend downward to the structure of the lower condenser box 2. The water molecules in the high-temperature steam will be condensed from gas into liquid condensed water and discharged downward into the lower condenser box 2 along with the high-temperature steam. In this process, the flow of steam and condensed water is very smooth, and blockage can be avoided. The high-temperature steam reaches secondary condensation in the lower condenser box 2 under natural conditions. The high-temperature steam of about 100°C discharged from the inner tank of the steam oven 2 is cooled to hot air with a lower risk of scalding, and then returns to the upper condenser box 1 again through the exhaust port 7. The condensed water is discharged from the lower condenser box 2 through the drain pipe 8, and the hot air will be discharged from the air outlet 4 under the action of the cold air blower 10.

[0037] In order to improve the condensation effect of the lower condensation box 2, a heat sink 9 is provided in the lower condensation box 2, and the heat sink 9 divides the inner cavity of the lower condensation box 2 into a plurality of connected condensation channels, wherein the heat sink 9 is distributed along the length direction of the lower condensation box 2 and has a connecting port, and the arrangement of this structure makes the air outlet smoother, and the heat sink 9 adopts an integrally formed structure, which includes a first heat sink and a first heat sink, and the first heat sink and the first heat sink are connected by a transverse sheet, which has the advantages of convenient manufacturing and assembly. The heat sink 9 itself plays the role of a heat sink, and under the blocking effect of the heat sink 9, the flow path of the steam becomes longer, thereby improving the condensation effect of the steam.

[0038] In order to improve the condensation effect in the upper condensation box 1, the condensation tube 5 is wound in an S shape. There are two of them and they are symmetrically distributed. A section of the steam interface 6 in the condensation tube 5 is close to the air inlet 3, and after bending, it extends downward to the lower condensation box 2 and is close to the air outlet 4. The exhaust port 7 is distributed in a row and is close to the air inlet 3. The exhaust port 7 is close to the fan and is at a long distance from the air outlet 4, which can further reduce the temperature.

[0039] like Figures 1 to 7As shown, the utility model steamer or steam oven includes the steam condensing device as mentioned above, which is arranged on the top of the steamer or steam oven. The steamer also includes the prior art structures such as water supply pipeline and steam generator, and the steam oven also has a heating assembly; the steam interface 6 of the steam condensing device is connected with the inner tank of the steamer or steam oven through a pipeline, and the air guide duct 11 extends to the panel of the steamer or steam oven, so as to blow out the hot air formed by the final cooling from the gap of the door.

[0040] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
