Description

Technical Field

[0001] The utility model relates to the field of cooking equipment, in particular to a cooking equipment with a steaming function. Background Art

[0002] Cooking equipment with steaming function (e.g., steamer, steam oven, etc.) heats water into steam and uses the steam to heat the food placed in the inner pot. Excessive exhaust steam has always been one of the main problems of cooking equipment with steaming function, which not only affects the user experience and the service life of the cabinet, but also affects the life of the water tank.

[0003] Furthermore, the prior art generally solves the above problem by setting a condensation box, for example, the Chinese invention patent "An exhaust condensation recovery system and integrated stove" with application number CN202311217573.5 (publication number CN117064229A), the Chinese utility model patent "An exhaust condensation structure and steaming cooking device" with patent number ZL 202222025337.0 (authorization announcement number CN219206604U), etc. However, this method has the following two problems:

[0004] (1) Poor condensation effect: The existing condensation box only transfers heat through metal sheets, which has low heat transfer efficiency. At the same time, the condensation effect of the condensation box needs to be coordinated with an appropriate internal volume. If the volume is too small, it will affect the condensation effect, while if the volume is too large, it will affect the reflux of condensed water formed by condensation;

[0005] (2) Occupation of internal installation space: The condensation box is generally installed on the upper mounting plate, and a large number of components are installed on the upper mounting plate at the same time. In order to meet the needs of the condensation box installation, the installation space of the components will inevitably be squeezed, resulting in an increase in the occasional failure rate of water pipes and electrical circuits. The crowded installation environment also devours the space for future improvement and optimization. Summary of the invention

[0006] The first technical problem to be solved by the utility model is to provide a cooking device with a steaming function and good condensation effect of externally discharged steam in view of the prior art.

[0007] The second technical problem to be solved by the utility model is to provide a cooking device with a steaming function, which has a good condensation effect on the externally discharged steam and occupies less installation space on the upper installation plate, in view of the existing technology.

[0008] The utility model solves at least one of the above technical problems by adopting a technical solution: a cooking device with a steaming function, comprising an inner pot, an upper mounting plate located above the inner pot, and an exhaust passage arranged on the upper mounting plate, characterized in that it also comprises a condensing device arranged beside the inner pot, the condensing device comprises a shell having an air inlet and an air outlet, the shell at least partially consisting of a condensing plate, the condensing plate having a phase change material and used for cooling the steam entering the shell,

[0009] Furthermore, the air inlet of the shell is fluidically connected to the air outlet of the inner container, and the air outlet is fluidically connected to the air inlet of the exhaust passage.

[0010] Furthermore, the shell is arranged up and down, the side wall of the shell is formed by the condensation plate, the air inlet is opened at the lower end of the shell and the air outlet is opened at the upper end of the shell. In this way, the exhaust gas enters the shell from bottom to top, exchanges heat with the condensation plate, and the steam in the exhaust gas is condensed and liquefied into condensed water, thereby reducing the amount of steam discharged.

[0011] Furthermore, a partition is provided inside the shell between the air inlet and the air outlet, and a ventilation gap is left between the partition and the inner surface of the shell. The partition is provided to slow down the flow rate of the airflow from the air inlet to the air outlet, so that the exhaust gas can fully exchange heat with the condensation plate, and then the steam in the exhaust gas can be fully condensed, and the amount of steam discharged can be better reduced. Among them, by providing the ventilation gap, on the one hand, it is ensured that the airflow flows smoothly from the air inlet to the air outlet, and on the other hand, the formed condensed water can flow down under the action of its own gravity and be recovered into the inner tank, so as to realize the recycling of condensed water.

[0012] Furthermore, the shell extends vertically, the partition is tilted up and down, and there are at least two partitions that are spaced apart up and down along the height direction of the shell, thereby further slowing down the flow speed of the airflow in the shell and better improving the condensation effect of steam in the exhaust gas.

[0013] Furthermore, the partitions are respectively arranged in parallel up and down, so that the airflow can flow regularly from the air inlet to the air outlet, avoiding turbulent airflow and retention in the shell.

[0014] Furthermore, the partition is composed of two pieces, namely an upper partition and a lower partition located below the upper partition, wherein the upper end of the upper partition is fixed to the top wall of the shell, and the other sides respectively form the above-mentioned ventilation gap with the side walls of the shell, and the lower end of the lower partition is fixed to the bottom wall of the shell, and the other sides respectively form the above-mentioned ventilation gap with the side walls of the shell. Thus, the structure of the shell can be simple and easy to assemble, and the arrangement of the ventilation gap can better ensure that the condensed water flows back to the inner tank from top to bottom.

[0015] Furthermore, the shell has a square shape, and the side wall of the shell is formed by bending a whole piece of the above-mentioned condensation plate along the circumferential direction, and the gap after the bending is sealed by a sealing strip, and the above-mentioned condensation plate is a hollow metal plate, and the metal plate is filled with the above-mentioned phase change material. This can make the structure of the shell more simple on the one hand, and on the other hand, it can make the phase change material flow better inside the metal plate, so as to better exchange heat with the steam.

[0016] Furthermore, the condensing device is arranged at the rear side of the inner container. The installation space at the rear side of the inner container is relatively sufficient, so that the installation space on the left and right sides of the inner container can be further avoided from being occupied without occupying the installation space on the upper installation plate.

[0017] Furthermore, the rear end of the upper mounting plate protrudes outwardly behind the inner tank, and the condensing device is suspended on the upper mounting plate, thereby facilitating the installation of the condensing device and allowing the installation position of the condensing device to be flexibly moved according to specific needs.

[0018] Furthermore, an exhaust fan is installed on the air inlet of the exhaust channel, and the exhaust fan has an exhaust inlet, which is connected to the air outlet of the shell through an exhaust pipe, and the air inlet of the shell is connected to the exhaust port of the liner through the exhaust pipe.

[0019] In addition, a vertically extending hanging rod is fixed to the upper end of the shell, and the upper end of the hanging rod is fixed to the upper mounting plate by a fastener, so as to form a smooth air path connection between the inner tank, the condensing device and the exhaust channel, and to stably install the condensing device through the coordination of the hanging rod, the exhaust pipe and the exhaust pipe.

[0020] Compared with the prior art, the utility model has the following advantages: the condensing device in the utility model is arranged beside the inner tank, and compared with the existing condensing box, it does not need to occupy the installation space on the upper mounting plate. In addition, the shell of the condensing device is at least partially composed of a condensing plate, which is used to cool the steam entering the shell and has a phase change material, which can greatly improve the condensation effect compared with the method of cooling only by a metal plate, thereby better reducing the amount of steam discharged.

[0030] As can be seen from the above, the condensing device 5 in the utility model is arranged beside the inner tank 1, and compared with the existing condensing box, it does not need to occupy the installation space on the upper mounting plate 2. In addition, the shell 50 of the condensing device 5 is at least partially composed of a condensing plate 51, which is used to cool the steam entering the shell 50 and has a phase change material.

Among them, by providing the ventilation gap 543, on the one hand, it is ensured that the airflow flows smoothly from the air inlet 521 to the air outlet 531; on the other hand, the formed condensed water can flow down under the action of its own gravity and be recovered into the inner tank 1, so as to realize the recycling of condensed water.

Thereby, the structure of the shell 50 can be made simple and easy to assemble, and the arrangement of the ventilation gap 543 can better ensure that the condensed water flows back to the inner tank 1 from top to bottom.
