Description

Technical Field

[0001] The present invention relates to the technical field of kitchen equipment, and in particular to a steam condensing device, a steam oven using the same, and a control method of the steam oven. Background Art

[0002] A 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. In this process, the high-temperature steam or hot air generated by the steam oven is discharged to the outside through the exhaust system, but this poses a certain risk of scalding.

[0003] In order to reduce the inconvenience caused to customers by the high-temperature steam and hot air discharged externally, steam-burning ovens equipped with condensing devices have appeared on the market. The high-temperature steam and hot air are connected to the inner tank and passed into the condensing tube of the condensing device for cooling, and then discharged from the steam-burning oven by the fan to avoid burns to customers caused by the discharged steam and hot air.

[0004] However, when the above-mentioned condensing device condenses steam, the condensed water is easily blocked in the condensing tube, making it difficult for the steam to be discharged smoothly for the natural cooling process, and it is easy to produce abnormal noise, resulting in poor actual condensation effect. In addition, when the steam oven is working in the oven mode, the high-temperature hot air generated in the inner tank is often mixed with a certain amount of oil smoke, resulting in the high-temperature hot air passing into the condensing device for cooling, and the oil smoke will remain in the condensing tube, causing the steam oven to have a cross-flavor when it is used, that is, the discharged cooling steam will inevitably have the smell of oil smoke, which seriously affects the use of the steam oven. Summary of the invention

[0005] The object of the present invention is to overcome the above-mentioned deficiencies of the prior art and to provide a steam condensing device, a steam oven using the same and a control method of the steam oven.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] A steam condensation device comprises a condensation box, wherein an air inlet and an air outlet are respectively provided on two opposite side walls of the condensation box, an inner condensation box is installed in the condensation box, a condensation tube leading to the inner condensation box is provided on the condensation box, a steam exhaust hole for mutual communication is provided between the condensation box and the inner condensation box, and a drain pipe is provided on the inner condensation box.

[0008] Preferably, a heat sink is provided in the condensing inner box, which separates the inner cavities of the condensing inner box and connects the two inner cavities through through holes opened on the heat sink. One end of the condensing pipe entering the condensing inner box and the exhaust holes are distributed on both sides of the heat sink.

[0009] Preferably, the heat sink comprises a first heat sink and a second heat sink, and the first heat sink and the second heat sink are respectively provided with a first through hole and a second through hole.

[0010] Preferably, the opening size of the through hole 1 is larger than the opening size of the through hole 2, and the number of the through holes 2 is greater than the number of the through holes 1.

[0011] Preferably, it further comprises an air cooler and an air duct, wherein the air cooler is arranged on one side of the air inlet, and the air duct is arranged on one side of the air outlet.

[0012] Preferably, the condenser is arranged in an S shape, and there are two condenser tubes which are relatively distributed in the condenser box.

[0013] Preferably, the exhaust holes are distributed in rows and arranged close to the air inlet.

[0014] The present invention also discloses a steam oven, comprising a steam condensing device, wherein a steam pipe passing into an inner tank is connected to the condensing tube, a steam valve is installed on the steam pipe, an oven tube passing into the inner tank is arranged on one side of the air outlet, and a baking valve is installed on the oven tube.

[0015] Preferably, the steam condensing device is arranged on the top of the inner tank.

[0016] The present invention also discloses a control method for a steam oven, comprising a steam oven, the steam oven is started, and a steam box mode or an oven mode is selected;

[0017] When the steamer mode is selected, the steam valve is opened and the baking valve is closed. At the same time, the steamer is working, and the steam generated in the inner tank enters the condensation box device through the steam pipe to condense. The condensed water of the steam is discharged to the outside through the drain pipe, and the cooled hot air is discharged to the outside together with the cold air blown out from the air outlet;

[0018] Until the steam box stops working and the steam valve is closed;

[0019] When the oven mode is selected, the baking valve opens and the steaming valve closes. At the same time, the oven works, and the hot air generated in the inner pot is transported to the side of the air outlet through the oven pipe and discharged outward together with the cold air blown out of the air outlet;

[0020] The oven stops working and the baking valve is closed.

[0021] The beneficial effects of the present invention are:

[0022] 1. The double condensation structure is adopted. By blowing cold air to the condenser tube, the high-temperature steam in the condenser tube is condensed once to reduce the temperature of the steam without generating too much condensed water, so that the steam can flow smoothly in the condenser tube to avoid condensed water blocking the condenser tube. The cooled steam is then passed into the condenser inner box to perform secondary condensation on the steam to enhance the condensation effect of the steam, thereby overcoming the trouble of high-temperature steam to users. At the same time, no abnormal sound is generated, which improves the user experience.

[0023] 2. By placing the naturally cooled condensing inner box at the bottom of the condensing box, the danger of steam leakage can be effectively avoided, and the leaked steam can also be discharged from the air outlet side under the action of the air cooler, so that the steam is cooled and turned into hot air with a lower temperature, so as to achieve the effect of zero steam discharge. At the same time, the condensed water of the steam condensation is discharged to the outside through the drain pipe of the condensing inner box to avoid the accumulation of condensed water and affect the continuous condensation effect of the device;

[0024] 3. By connecting the oven tube to the inner tank of the steam oven, when the oven mode is selected, since no steam is generated in the inner tank, only high-temperature hot air is generated, the hot air does not need to pass into the condensation box, but is discharged after being cooled by the cold air blown by the cold air blower, which effectively solves the problem of residual smoke and oil stains in the condensation box, and also solves the problem of odor when the steam oven is used.

DETAILED DESCRIPTION

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0036] In the description of this specification, the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or unit referred to must have a specific direction, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0037] Embodiment 1:

[0038] like Figure 1 to Figure 5 As shown, this embodiment discloses a steam condensation device, including a condensation box 1, a cold air blower 3, and an air duct 4. A condensation inner box 2 is installed in the condensation box 1. The condensation box 1 is sleeved on the outer periphery of the condensation inner box 2. The condensation inner box 2 is fitted on the lower part of the condensation box 1. The condensation box 1 and the condensation inner box 2 are both flat rectangular structures with a hollow inner cavity, and are welded from stainless steel throughout.

[0039] An air inlet 12 and an air outlet 13 are respectively provided on the opposite side walls of the condensation box 1. The air cooler 3 is arranged on one side of the air inlet 12. The air cooler 3 can be a cross-flow fan. The air cooler 3 blows cold air into the condensation box 1 through the air inlet 12. The air duct 4 is arranged on one side of the air outlet 13. The cold air blown into the condensation box 1 by the air cooler 3 is discharged to the air duct 4 through the air outlet 13, and then guided through the air duct 4 and discharged outward.

[0040] The condensation box 1 is provided with a condensation tube 11 which leads into the condensation inner box 2. The condensation tube 11 is made of stainless steel or copper. The condensation tube 11 is arranged in an S shape. There are two condensation tubes 11 which are relatively distributed in the condensation box 1. The condensation tube 11 is bent and arranged between the air inlet 12 and the air outlet 13.

[0041] The condenser 11 is used to transport high-temperature steam to be cooled. A section of the condenser 11 extending into the condenser box 1 is arranged near the air inlet 12 , and a section of the condenser 11 passing into the condenser inner box 2 is arranged near the air outlet 13 .

[0042] The air cooler 3 blows cold air to the condenser 11 through the air inlet 12 to condense the high-temperature steam in the condenser 11, so as to reduce the temperature of the steam without producing too much condensed water, so that the steam can flow smoothly in the condenser 11, avoiding the condensed water from being blocked in the condenser 11 and affecting the condensation effect. At the same time, the steam condensation does not produce abnormal noise, thereby improving the user experience.

[0043] In order to further improve the steam condensation effect, a heat sink 21 is provided in the condensation inner box 2. The heat sink 21 is used to dissipate heat and condense the steam, that is, the steam is secondary condensed through the heat sink 21 to overcome the trouble of high-temperature water vapor discharge to the user and avoid the problem of steam scalding the user.

[0044] The condensation inner box 2 is provided with a drain pipe 23, and the condensed water of the steam condensation is discharged outward through the drain pipe 23 of the condensation inner box 2 to avoid the accumulation of condensed water and the influence on the continuous condensation effect.

[0045] The heat sink 21 separates the inner cavities of the condensing inner box 2 and connects the two inner cavities through the through holes opened on the heat sink 21. An exhaust hole 22 for mutual communication is opened between the condensing box 1 and the condensing inner box 2. One end of the condensing pipe 11 that passes into the condensing inner box 2 and the exhaust hole 22 are distributed on both sides of the heat sink 21.

[0046] The steam passes into the condensation inner box 2 through the condenser tube 11 and then flows to the exhaust hole 22 through the through hole of the heat sink 21. At the same time, the steam is converted into hot air with lower temperature through heat dissipation, cooling and condensation of the heat sink 21. The hot air returns to the condensation box 1 through the exhaust hole 22.

[0047] The exhaust holes 22 are distributed in a row and are arranged close to the air inlet 12. The hot air is then mixed with the cold air of the air cooler 3 to be cooled, and is guided and discharged through the air duct 4 outside the air outlet 13, further reducing the risk of hot air scalding the user and improving the safety of use.

[0048] In order to further improve the condensation effect of the condensation inner box 2, the heat sink 21 includes a first heat sink 211 and a second heat sink 213. The first heat sink 211 is arranged near one end of the condensation tube 11 entering the condensation inner box 2, and the second heat sink 213 is arranged near the exhaust hole 22. The first heat sink 211 and the second heat sink 213 are respectively provided with a through hole 1 212 and a through hole 214. The opening size of the through hole 1 212 is larger than the opening size of the through hole 214, and the number of the through holes 214 is more than the number of the through holes 1 212. Through the arrangement of the through holes 1 212 and the through holes 214, the time for the steam to pass through the first heat sink 211 and the second heat sink 213 in sequence is extended, thereby enhancing the effect of the heat sink 21 on condensing the steam to further reduce the temperature of the steam.

[0049] At the same time, by arranging the naturally cooled condensing inner box 2 at the lower part of the condensing box 1, the risk of steam leakage can be effectively avoided, and the steam leaked from the condensing inner box 2 can also be discharged from the side of the air outlet 13 under the action of the air cooler 3, so that the steam is cooled and turned into hot air with lower temperature, so as to achieve the effect of zero steam discharge.

[0050] Embodiment 2:

[0051] like Figure 1 , Figure 6 to Figure 9 As shown, this embodiment discloses a steam oven, including a steam condensing device, the condensing tube 11 is connected to a steam pipe 5 passing into an inner pot 7, a steam valve 71 is installed on the steam pipe 5, an oven tube 6 passing into the inner pot 7 is arranged on one side of the air outlet 13, one end of the oven tube 6 is fixed on the air duct 4 and passes through the air duct 4 to extend to the side of the air outlet 13, a baking valve 72 is installed on the oven tube 6, and the steam condensing device is arranged on the top of the inner pot 7.

[0052] This embodiment also discloses a control method for a steam oven, comprising a steam oven, the steam oven is started, and a steam box mode or an oven mode is selected;

[0053] When the steamer mode is selected, the steam valve 71 is opened and the baking valve 72 is closed to prevent the steam generated in the inner pot 7 from being transported through the oven tube 6. At the same time, the steamer is working, and the steam generated in the inner pot 7 enters the condensation box device through the steam pipe 5 to condense. The condensed water of the steam is discharged to the outside through the drain pipe 23, and the cooled hot air is discharged to the outside together with the cold air blown out from the air outlet 13.

[0054] Until the steam box stops working, the steam valve 71 is closed;

[0055] When the oven mode is selected, the baking valve 72 is opened and the steaming valve 71 is closed to prevent the hot air generated in the inner pot 7 from being transported through the steam pipe 5. At the same time, when the oven is working, the hot air generated in the inner pot 7 is transported to the side of the air outlet 13 through the oven pipe 6 and discharged outward together with the cold air blown out of the air outlet 13;

[0056] The oven is stopped and the baking valve 72 is closed.

[0057] When the oven is working, since no steam is generated in the inner tank 7 but only high-temperature hot air, the hot air does not need to be passed into the condensation box 1 for condensation, but is discharged after being mixed with the cold air blown by the cold air blower 3 and cooled. In addition, the hot air is generally mixed with oil smoke during baking, which can effectively solve the problem of residual oil smoke and oil stains in the condensation box 1, and also solve the problem of odor contamination when the steam oven is used.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
