Description

Technical Field

[0001] The utility model relates to the field of steam boxes and steam ovens, in particular to a condensing device applied to steam boxes and steam ovens. Background Art

[0002] When a steamer or steam oven uses steam for cooking, the water in the water box is continuously evaporated through an evaporating plate or an external evaporator, thereby providing hot steam to the inner pot to cook the food.

[0003] In this process, due to the continuous input of steam, if no channel for discharging steam to the outside is provided, the internal pressure will become increasingly greater. Therefore, a steam discharge pipe / hole is generally provided on the side or top of the steam box.

[0004] The existing processing method is that when the steamer / steam oven is used on an integrated stove / integrated cooking center, it is connected to the smoke exhaust duct and directly discharged through the smoke exhaust system of the integrated bellows; when it is used as a separate appliance, a cooling fan is generally set on the top to blow the hot steam from the steam oven directly to the front when it is working; some also blow the hot steam into the insulation cavity of the door body through the cooling fan, and then collect it in the waste water box / trough below through the insulation cavity.

[0005] However, the above method consumes a lot of energy because the cooling fan takes away too much steam and cannot recover the water and waste heat therein. It also easily makes the surrounding environment humid, which is not conducive to the maintenance of kitchen hygiene conditions.

[0006] Therefore, the inventor conducted further research on this and developed a condensing device for use in steamers and steam ovens, which resulted in the present invention. Utility Model Content

[0007] The utility model aims to provide a condensing device applied to a steam box and a steam oven, which can recycle condensed water.

[0008] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0009] A condensing device used in a steamer or a steam oven, comprising

[0010] A condensation box, wherein a condensation plate is arranged in the condensation box, and the condensation plate divides the condensation box into an upper cavity and a lower cavity, wherein a condensation air duct is arranged in the upper cavity, and a condensation space is left between the condensation air duct and the upper cavity, and the condensation space is connected to the exhaust joint;

[0011] The bottom of the lower cavity is an inclined bottom plate, and a drainage joint is arranged at the lowest point of the lower cavity;

[0012] A plurality of through holes are also arranged around the condensation plate.

[0013] The condensation air duct is connected to the cooling fan, and the exhaust joint is connected to the inner tank, that is, the steam discharged from the inner tank flows in the condensation space around the condensation air duct, and is converted into condensed water through heat exchange and returned to the inner tank from the drain joint of the lower cavity, which can be reused repeatedly to reduce the discharge of water vapor.

[0014] Furthermore, the through hole connecting the upper cavity and the lower cavity is defined as the first through hole, and the through hole connecting the lower cavity and the condensation air duct is defined as the second through hole; the condensation space is located on both sides and above the condensation air duct, and the water vapor entering from the exhaust joint passes through the top of the condensation air duct, enters the lower cavity through the first through hole, and then rises from the lower cavity through the second through hole to the condensation air duct.

[0015] By means of the above-mentioned opening method, the flow length of the water vapor after coming out of the exhaust joint can be extended as much as possible, so that as much condensed water as possible can be retained in the lower cavity, thereby realizing the recycling of the condensed water.

[0016] Furthermore, the first through holes are distributed on both sides of the condensation air duct, the second through holes are located above the drain joint, and the first through holes on the same side as the exhaust joint are far away from the exhaust joint.

[0017] Try to extend the path of water vapor as much as possible, while also considering draining away any prematurely condensed water.

[0018] Furthermore, the first through hole and the second through hole are narrow and long holes.

[0019] The narrow and long holes include oval, waist-shaped, rectangular and other through holes.

[0020] Furthermore, the input end of the condensing air duct is connected to the cooling fan, and the drain joint is located below the input end of the condensing air duct.

[0021] Furthermore, a mounting bracket is provided on the outside of the condensation box.

[0022] Furthermore, the aperture of the steam exhaust joint is larger than the aperture of the water discharge joint.

[0023] The pressure value delivered to the condensation box process when relieving hot steam discharge.

[0024] Furthermore, the inclination angle of the bottom plate of the lower cavity is 3-5°.

[0025] The condensed water can quickly flow out of the condensation box, reducing the weight of the box and avoiding excessive pressure in the steam oven cavity caused by the accumulated water overflowing the drain port.

[0026] Furthermore, a cover plate is provided on the top of the condensation box, and a sealing gasket is provided under the cover plate.

[0027] Considering the industrial processing cost and maintenance convenience, it is difficult to form the condensation box as a whole in one piece, so the top is installed with a cover plate and a sealing gasket, and screwed together.

[0028] After adopting the above scheme, the utility model has the following advantages compared with the prior art:

[0029] In a limited space, the cooling path of the steam is extended as much as possible so that the water vapor can be condensed to the greatest extent, thereby reducing the discharge of water vapor and reducing the impact on the surrounding environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0037] like Figure 1 As shown, a condensing device applied to a steamer or a steam-oven comprises a condensing box, which is a box structure as a whole, a cover plate is arranged on the top of the condensing box, a sealing gasket is arranged under the cover plate, a condensing plate is arranged inside, and the condensing plate divides the condensing box into an upper cavity and a lower cavity; wherein, a through-type condensing air duct is arranged in the upper cavity, and the condensing air duct is formed by an inverted U-shaped semi-enclosed structure and a part of the condensing plate as a bottom plate, one end of the condensing air duct is connected to the cooling fan, and the other end serves as an exhaust port for cold air; mounting brackets are arranged on both sides of the outside of the condensing box for fixing the condensing box.

[0038] The gaps on both sides of the condensation air duct and between the upper surface and the upper cavity can be used as condensation space. Figure 2 Taking the angle as an example, a steam exhaust joint is arranged on the side wall of the upper cavity corresponding to the right side of the condensing box, and the steam exhaust joint is connected with the inner tank of the steamer or steam oven for discharging hot steam; 3 waist holes are arranged on the left side of the condensing plate, and 1 waist hole is arranged on the right side, and the above waist holes are all located on the outside of the condensing air duct; 7 waist holes are arranged on the side of the condensing plate close to the condensing air duct, and the 7 waist holes are located in the condensing air duct.

[0039] refer to Figure 3 The bottom of the lower cavity is an inclined bottom plate, and a drainage joint is provided at the lowest point of the lower cavity to discharge the condensed water vapor.

[0040] After the water vapor from the exhaust joint enters the upper cavity, a small amount of water vapor that is condensed first can enter the lower cavity through a waist hole on the right, while most of the remaining water vapor encounters the obstruction of the condensation air duct, rises along the condensation air duct, crosses the top of the condensation air duct, and then descends and enters the lower cavity through the three waist holes on the right. In this process, the water content in the hot steam has been greatly reduced through condensation, and combined with the action of the cooling fan, the entire condensation box continues to cool down the surface area, and the remaining very small amount of gas rises through 7 waist holes into the condensation air duct and is discharged with the airflow blown out by the cooling fan.

[0041] Preferably, the inclination angle of the bottom plate of the lower cavity is 4° to facilitate the discharge of condensed water vapor from the drainage joint.

[0042] The above are only specific embodiments of the present utility model. At the same time, all words such as "upper, lower, left, right, middle" involved in the present utility model are for reference only and are not absolutely limiting. Any non-substantial changes made using the present utility model shall be deemed as an infringement of the protection scope of the present utility model.
