Steam oven with circulating heat distribution structure

Abstract

This utility model discloses a steam oven with a circulating heating structure, including a cabinet with a steaming / baking cavity and a circulating cavity. A circulating wheel is provided within the circulating cavity, which is connected to the steaming / baking cavity via several connecting holes. These connecting holes include first connecting holes and second connecting holes located on opposite sides of the circulating wheel. The circulating wheel can rotate clockwise or counterclockwise, forming airflow into the steaming / baking cavity from either the first or second connecting hole. By arranging the steaming / baking cavity, circulating cavity, and circulating wheel on the cabinet, and connecting the circulating cavity to the steaming / baking cavity via the first and second connecting holes on opposite sides of the circulating wheel, this utility model achieves a more uniform temperature within the steaming / baking cavity. The circulating wheel can rotate alternately clockwise and counterclockwise, alternately forming airflows flowing into the steaming / baking cavity from the first and second connecting holes. This creates airflows with opposite directions within the steaming / baking cavity, effectively mixing high and low temperature air, resulting in high baking / steaming efficiency and excellent cooking effects.

Description

Technical Field

[0001] This utility model relates to the field of steam oven technology, and in particular to a steam oven with a circulating heat distribution structure. Background Technology

[0002] A steam oven is a cooking appliance that combines baking and steaming functions. Existing steam ovens mainly consist of a cabinet and a heating element. The cabinet has a steaming / baking cavity, and the heating element is located inside the steaming / baking cavity. However, the temperature is higher near the heating element and lower further away, resulting in uneven temperature distribution within the steaming / baking cavity and suboptimal baking / steaming effects. Utility Model Content

[0003] The purpose of this invention is to provide a steam oven with a circulating heating structure to solve the problem that the baking / steaming effect of existing steam ovens is poor due to uneven temperature inside the steam oven cavity.

[0004] This utility model is achieved through the following technical solution:

[0005] A steam oven with a circulating heating structure includes a housing, which has a steaming and baking cavity and a circulating cavity. A circulating wheel is provided in the circulating cavity. The circulating cavity is connected to the steaming and baking cavity through a plurality of connecting holes. The plurality of connecting holes include at least a first connecting hole and a second connecting hole respectively disposed on opposite sides of the circulating wheel. The circulating wheel can rotate clockwise or counterclockwise relative to the housing, forming an airflow in the circulating cavity that flows into the steaming and baking cavity from the first connecting hole or the second connecting hole.

[0006] Furthermore, the circulating wheel has a base plate and a plurality of deflector blades. The plurality of deflector blades are disposed on the side of the base plate opposite to the communicating hole and are spaced apart in the circumferential direction of the base plate. Each deflector blade extends radially along the base plate and is perpendicular to the base plate.

[0007] Furthermore, the deflector extends inward from the outer edge of the substrate.

[0008] Furthermore, the deflector blade has an integrally formed flange that abuts against the substrate.

[0009] Furthermore, the deflector is detachably and fixedly connected to the substrate.

[0010] Furthermore, the plurality of the connecting holes also include third connecting holes, which are directly opposite the annular wheel and there are several of them.

[0011] Furthermore, a first heating element is provided inside the circulation cavity, and the first heating element is at least partially arranged around the circulation wheel.

[0012] Furthermore, the circulating cavity is located on the rear side of the steaming and baking cavity, and the first connecting hole and the second connecting hole are opened on the rear wall of the steaming and baking cavity and are respectively located on the left and right sides of the circulating wheel. There are several first connecting holes and several second connecting holes, with several first connecting holes arranged vertically at intervals and several second connecting holes arranged vertically at intervals.

[0013] Furthermore, the steam oven cavity is provided with two second heating tubes, which are respectively located on opposite sides of the circulating wheel.

[0014] Furthermore, the housing also has an assembly cavity located on one side of the circulation cavity, and the assembly cavity is provided with a motor that drives the circulation wheel to rotate clockwise or counterclockwise.

[0015] The advantage of this technical solution is that by configuring a steaming and baking cavity, a circulation cavity, and a circulation wheel on the housing, the circulation cavity is connected to the steaming and baking cavity through at least the first and second connecting holes on opposite sides of the circulation wheel. The circulation wheel can rotate clockwise and counterclockwise alternately, forming airflows flowing into the steaming and baking cavity from the first connecting hole and airflows flowing into the steaming and baking cavity from the second connecting hole. This creates airflows with opposite directions of flow within the steaming and baking cavity, thus fully mixing high and low temperature air, resulting in uniform temperature within the steaming and baking cavity, high baking / steaming efficiency, and excellent cooking effect.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Figure 1-8 As shown, the steam oven with a circulating heating structure includes a housing 1, which has a steaming and baking cavity 101 and a circulating cavity 102. A circulating wheel 2 is provided in the circulating cavity 102. The circulating cavity 102 is connected to the steaming and baking cavity 101 through a plurality of connecting holes 103. The plurality of connecting holes 103 include at least a first connecting hole 104 and a second connecting hole 105 respectively disposed on opposite sides of the circulating wheel 2. The circulating wheel 2 can rotate clockwise or counterclockwise relative to the housing 1, forming an airflow in the circulating cavity 102 that flows into the steaming and baking cavity 101 from the first connecting hole 104 or the second connecting hole 105. When the circulating wheel 2 rotates clockwise and counterclockwise alternately, airflows flowing into the steam-baking cavity 101 from the first connecting hole 104 and from the second connecting hole 105 are alternately formed in the circulating cavity 102. This creates airflows with opposite flow directions in the steam-baking cavity 101, thus fully mixing high and low temperature air, resulting in uniform temperature in the steam-baking cavity 101, high baking / steaming efficiency, and excellent cooking effect.

[0028] In summary, this embodiment provides a steam oven with a circulating heating structure to solve the problem of poor baking / steaming effect caused by uneven temperature in the steam oven cavity in existing steam ovens. This is mainly achieved by configuring a steam oven cavity 101, a circulating cavity 102, and a circulating wheel 2 on the oven body 1. The circulating cavity 102 is connected to the steam oven cavity 101 via at least a first connecting hole 104 and a second connecting hole 105 on opposite sides of the circulating wheel 2. The circulating wheel 2 can rotate alternately clockwise and counterclockwise, alternately forming airflows flowing into the steam oven cavity 101 from the first connecting hole 104 and from the second connecting hole 105 within the circulating cavity 102. This creates alternating airflows with opposite directions within the steam oven cavity 101, effectively mixing high and low temperature air, resulting in uniform temperature within the steam oven cavity 101, high baking / steaming efficiency, and excellent cooking effect.

[0029] In this embodiment of the invention, the circulating wheel 2 has a substrate 201 and a plurality of deflectors 202. The deflectors 202 are disposed on the side of the substrate 201 facing the connecting hole 103 and are spaced apart in the circumferential direction of the substrate 201. Each deflector 202 extends radially along the substrate 201 and is perpendicular to the substrate 201. By configuring the circulating wheel 2 with a substrate 201 and a plurality of deflectors 202, and the deflectors 202 extending radially along the substrate 201 and perpendicular to the substrate 201, the circulating wheel 2 can generate airflow from the first connecting hole 104 into the steaming and baking cavity 101 and airflow from the second connecting hole 105 into the steaming and baking cavity 101 when rotating clockwise or counterclockwise (air is thrown out radially in the circulating wheel 2 to generate airflow). This creates alternating airflows with opposite flow directions in the steaming and baking cavity 101, mixing high and low temperature air, resulting in uniform temperature in the steaming and baking cavity 101, and improving baking / steaming efficiency and cooking effect.

[0030] In this embodiment of the invention, the deflector 202 extends inward from the outer edge of the substrate 201, and the deflector 202 occupies 1 / 2 to 4 / 5 of the radius of the substrate 201. This arrangement, by configuring the deflector 202 to extend inward from the outer edge of the substrate 201, results in a large airflow generated when the annular wheel 2 rotates.

[0031] In this embodiment of the invention, a flange 203 is integrally formed on the deflector 202 to abut against the base plate 201. The above-mentioned arrangement, by configuring the flange 203 on the deflector 202 to abut against the base plate 201, makes the assembly of the deflector 202 and the base plate 201 stable.

[0032] In this embodiment of the invention, the deflector 202 is detachably and fixedly connected to the base plate 201. Specifically, the base plate 201 is connected to the flange 203 by bolts. This arrangement, by configuring the deflector 202 and the base plate 201 to be detachably and fixedly connected, facilitates the disassembly and replacement of the deflector 202.

[0033] In other embodiments, the deflector 202 may also be integrally formed on the substrate 201.

[0034] In this embodiment of the invention, the plurality of connecting holes 103 further includes a third connecting hole 106, which faces the circulating wheel 2 and there are several of them. By configuring the third connecting holes 106 facing the circulating wheel 2, when the circulating wheel 2 rotates, some airflow flows into the steam oven cavity 101 through the third connecting hole 106, mixing with the airflow flowing into the steam oven cavity 101 from the first connecting hole 104 or the second connecting hole 105. This results in excellent mixing and uniform temperature within the steam oven cavity 101.

[0035] In this embodiment of the invention, a first heating element 3 is provided inside the circulation cavity 102, and the first heating element 3 is at least partially arranged around the outside of the circulation wheel 2. This arrangement, by placing the first heating element 3, at least partially arranged around the outside of the circulation wheel 2, within the circulation cavity 102, ensures that the airflow flowing into the steam-baking cavity 101 from the first connecting hole 104 or the second connecting hole 105 carries a certain temperature, resulting in rapid heating of the steam-baking cavity 101 and excellent baking / steaming efficiency.

[0036] In this embodiment of the invention, the circulation cavity 102 is located on the rear side of the steaming and baking cavity 101. The first connecting hole 104 and the second connecting hole 105 are formed on the rear wall of the steaming and baking cavity 101 and are respectively located on the left and right sides of the circulation wheel 2. There are multiple first connecting holes 104 and multiple second connecting holes 105, with the first connecting holes 104 and the second connecting holes 105 arranged at vertical intervals. This arrangement, by placing the circulation cavity 102 on the rear side of the steaming and baking cavity 101 and placing the first connecting holes 104 and the second connecting holes 105 on the rear wall of the steaming and baking cavity 101 and respectively on the left and right sides of the circulation wheel 2, makes the configuration of the circulation cavity 102 and the steaming and baking cavity 101 reasonable and compact, ensuring uniform mixing of airflow within the steaming and baking cavity 101.

[0037] In this embodiment of the invention, a second heating element 4 is provided inside the steam oven cavity 101. There are two second heating elements 4, which are respectively arranged on opposite sides of the circulating wheel 2. By arranging two second heating elements 4 on opposite sides of the circulating wheel 2 inside the steam oven cavity 101, the steam oven cavity 101 heats up quickly, resulting in excellent baking / steaming efficiency. At the same time, the relative positions of the two second heating elements 4 and the circulating wheel 2 are reasonable and compact, ensuring that the airflow is evenly mixed inside the steam oven cavity 101.

[0038] In this embodiment of the invention, the housing 1 further includes an assembly cavity 107 located on one side of the circulation cavity 102. The assembly cavity 107 contains a motor 6 that drives the circulation wheel 2 to rotate clockwise or counterclockwise. This arrangement, by configuring the assembly cavity 107 on one side of the circulation cavity 102 and placing the motor 6 within the assembly cavity 107 to drive the circulation wheel 2 to rotate clockwise or counterclockwise, prevents airflow from overflowing from the circulation cavity 102 into the assembly cavity 107, thus avoiding overheating of the motor 6's operating environment and affecting its service life.
