Through the heat dissipation channel structure which surrounds the hot steam pipe and has the bottom sectional area larger than the top sectional area, when heat dissipation airflow is exhausted to the exhaust cavity, the airflow direction is changed from original horizontal exhaust to vertical upward exhaust. And the airflow direction is changed, so that the radiating airflow does not impact the exhaust cavity, the phenomenon that the airflow rotates in the cavity is avoided, and the vortex in the cavity is reduced. Meanwhile, the two air flows are in the same direction, so that the problem that the hot steam is prevented from being discharged from the hot steam outlet when the radiating air flow serves as an air curtain is solved.

Description

Technical Field

[0001] The present disclosure relates to the technical field of integrated cooking stoves, and in particular to an integrated cooking stove and a heat dissipation and exhaust structure thereof. Background Art

[0002] An integrated cooking stove is a stove that integrates a stove (mainly a gas stove) and a cooking device (such as a steamer, oven, or steam-bake combination). Currently, the integrated cooking products on the market have electronic components that generate heat when working, as well as a heat dissipation system installed in the inner cavity of the stove shell. Figure 1 The heat dissipation system includes a heat dissipation channel (including heat dissipation channel 101 and heat dissipation channel 102) arranged in the inner cavity of the stove shell and a fan (the fan includes a fan impeller 103 and a volute 104) arranged in the heat dissipation channel. The cooking device has a built-in inner cavity exhaust port, and the discharged hot steam is connected to the exhaust box 106 through the hot steam pipe 105, and finally the gas blown out of the heat dissipation outlet 107 of the heat dissipation channel of the stove cavity is gathered in the exhaust cavity 108, and discharged together from the exhaust grille 109 outlet on the glass panel of the stove. However, the hot steam discharged from the cooking device such as the steam oven and the heat dissipation airflow in the stove cavity are discharged together, which causes some problems: the direction of the hot steam discharged from the cooking device (such as the steam oven) is vertically upward, while the direction of the gas coming out of the heat dissipation channel of the stove cavity is horizontal, and the heat dissipation outlet is usually higher than the hot steam outlet. Therefore, the gas coming out of the stove cavity will form a wind curtain, which hinders the discharge of hot steam and even causes the phenomenon of air flow backflow. In addition, since the gas discharged from the stove cavity for heat dissipation is in a horizontal direction, the gas will first impact the exhaust cavity wall instead of being discharged vertically upward, causing the airflow to swirl in the cavity and the airflow to separate to form vortices, affecting the exhaust heat dissipation efficiency. Summary of the invention

[0003] The technical problem to be solved by the present disclosure is to overcome the defect of low exhaust and heat dissipation efficiency in the prior art and to provide an integrated cooking stove and a heat dissipation and exhaust structure thereof.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0023] The positive and progressive effects of this disclosure are:

[0024] The present invention uses a heat dissipation channel structure that surrounds the hot steam pipe and has a bottom cross-sectional area larger than a top cross-sectional area, so that when the heat dissipation airflow is discharged to the exhaust cavity, the airflow direction changes from the original horizontal discharge to vertical upward. The change in the airflow direction prevents the heat dissipation airflow from impacting the exhaust cavity, avoids the phenomenon of the airflow spinning in the cavity, and reduces the vortex in the cavity. At the same time, since the two airflows have the same direction, the problem of the heat dissipation airflow acting as a wind curtain to hinder the discharge of hot steam from the hot steam outlet is also eliminated.

[0031] The present disclosure is further described below by way of examples, but the present disclosure is not limited to the scope of the examples.

[0032] Prefixes such as "first" and "second" are used in the embodiments of the present disclosure only to distinguish different description objects, and have no limiting effect on the position, order, priority, quantity or content of the described objects. The use of prefixes such as ordinal numbers to distinguish description objects in the embodiments of the present disclosure does not constitute a limitation on the described objects. For the statement of the described objects, please refer to the description in the context of the claims or embodiments, and no unnecessary limitation should be constituted due to the use of such prefixes. In addition, in the description of the present embodiment, unless otherwise specified, the meaning of "plurality" is two or more.

[0033] Example 1

[0034] The exhaust paths of integrated cooking products currently on the market are as follows: Figure 2As shown, the solid arrows represent the direction of the heat dissipation airflow in the cavity of the integrated cooking stove, and the dotted arrows represent the direction of the hot steam discharged from the cooking device such as the steam oven. When the fan in the integrated cooking stove is running, the airflow in the cavity is sucked in from the inlet of the volute by the negative pressure generated by the impeller, and after rotation, it is discharged from the outlet of the volute. The heat dissipation airflow flows through the heat dissipation channel and is discharged from the heat dissipation outlet to the exhaust cavity. The hot steam in the inner cavity of the cooking device is discharged from the exhaust port, flows through the hot steam pipe and the exhaust box, and is finally discharged into the exhaust cavity.

[0035] from Figure 3 It can be seen that since the heat dissipation airflow is discharged horizontally to the exhaust cavity and the outlet position is higher than the hot steam outlet, it is similar to an air curtain, which hinders the vertical upward hot steam discharge. In addition, the horizontal discharge of the heat dissipation airflow will impact the inner wall of the exhaust cavity, swirl in the exhaust cavity, and generate vortices.

[0036] This embodiment provides a heat dissipation and exhaust structure of an integrated cooking stove, which eliminates the mutual influence of two airflows and the phenomenon of swirling heat dissipation airflow by redesigning the exhaust path of the heat dissipation airflow and changing its exhaust direction.

[0037] See also Figure 4 The heat dissipation and exhaust structure of the integrated cooking stove includes: a hot steam pipe 1, an exhaust box 2 and a heat dissipation channel 3.

[0038] The heat dissipation outlet of the heat dissipation channel 3 and the hot steam outlet of the hot steam pipe 1 are arranged inside the exhaust box 2. The heat dissipation outlet surrounds the hot steam pipe 1. The pipe diameter of the heat dissipation outlet is larger than the pipe diameter of the hot steam outlet.

[0039] In this embodiment, the heat dissipation channel structure is surrounded by the hot steam pipe, and the bottom cross-sectional area is larger than the top cross-sectional area, so that when the heat dissipation airflow is discharged to the exhaust cavity, the airflow direction changes from the original horizontal discharge to vertical upward. The change in the airflow direction prevents the heat dissipation airflow from impacting the exhaust cavity, avoids the phenomenon of the airflow spinning in the cavity, and reduces the vortex in the cavity. At the same time, since the two airflows have the same direction, the problem of the heat dissipation airflow acting as a wind curtain to hinder the discharge of hot steam from the hot steam outlet is also eliminated.

[0040] In an optional embodiment, the bottom cross-sectional area of ​​the heat dissipation channel in the exhaust box is larger than the top cross-sectional area of ​​the shape. For example, the shape of the heat dissipation channel in the exhaust box can be a truncated cone with a bottom cross-sectional area larger than the top cross-sectional area.

[0041] In this embodiment, by utilizing the shape of the heat dissipation channel in the exhaust box, which has a large bottom cross-section and a small top cross-section, after the heat dissipation airflow enters the exhaust box through the heat dissipation channel, the closer the heat dissipation airflow is to the heat dissipation outlet, the greater the airflow speed, thereby improving the efficiency and effect of exhaust heat dissipation.

[0042] In an optional embodiment, the first distance is smaller than the second distance.

[0043] The first distance is the distance between the top of the heat dissipation outlet and the bottom of the exhaust box, and the second distance is the distance between the hot steam outlet and the bottom of the exhaust box.

[0044] In this embodiment, since the position of the hot steam outlet is higher than the position of the heat dissipation outlet and the characteristic that the speed of the hot steam is faster than the speed of the heat dissipation airflow is utilized, a jet drainage effect occurs, guiding the heat dissipation airflow to be discharged vertically upward, thereby improving the overall exhaust and heat dissipation efficiency of the integrated cooking stove.

[0045] In an alternative embodiment, see Figure 4 The heat dissipation and exhaust structure of the integrated cooking stove also includes an exhaust grille 4.

[0046] The exhaust grille 4 and the exhaust box 2 form an exhaust chamber 5 .

[0047] The heat dissipation channel 3 is connected to the exhaust cavity 5 and the exhaust box 2 .

[0048] In an optional implementation, the second distance is less than or equal to the third distance.

[0049] The second distance is the distance between the hot steam outlet and the bottom of the exhaust box 2 , and the third distance is the distance between the hot steam outlet and the exhaust grille 4 .

[0050] In this embodiment, the distance between the hot steam outlet and the bottom of the exhaust box is less than or equal to the distance between the hot steam outlet and the exhaust grille, thereby improving the jet drainage effect of the hot steam and allowing the heat dissipation airflow to better dissipate heat in the exhaust cavity.

[0051] In an optional embodiment, one end of the heat dissipation inlet of the heat dissipation channel is connected to the fan, and the other end of the heat dissipation inlet is connected to the heat dissipation outlet.

[0052] The fan is used to inhale airflow in the integrated cooking stove and discharge the airflow from the heat dissipation channel when it is running.

[0053] In an optional embodiment, the heat dissipation channel includes a first heat dissipation channel and a second heat dissipation channel.

[0054] The first heat dissipation channel and the second heat dissipation channel are arranged horizontally.

[0055] The heat dissipation inlet of the first heat dissipation channel is connected to the fan. The heat dissipation outlet of the first heat dissipation channel is connected to the heat dissipation inlet of the second heat dissipation channel. The heat dissipation outlet of the second heat dissipation channel is the heat dissipation outlet of the heat dissipation channel.

[0056] The fan is used for sucking airflow in the integrated cooking stove when in operation, and discharging the airflow from the first heat dissipation channel and the second heat dissipation channel.

[0057] In this embodiment, the heat dissipation channel can be formed in one piece or can be divided into two parts. The fan blows air horizontally from the heat dissipation channel into the heat dissipation channel in the exhaust box, thereby improving the heat dissipation efficiency.

[0058] A specific example is introduced below to explain in detail the heat dissipation and exhaust structure of the integrated cooking stove of this embodiment.

[0059] Figure 5 This is a schematic diagram of the heat dissipation and exhaust structure of this example.

[0060] The heat dissipation and exhaust structure includes an exhaust grille 4, an exhaust cavity 5, an exhaust box 2, a hot steam pipe 1, and a heat dissipation channel 3; the heat dissipation channel 3 includes an exhaust box internal heat dissipation channel 501. It can be seen that in this example, the shape of the exhaust box internal heat dissipation channel 501 is set to a truncated cone shape, and the heat dissipation outlet of the heat dissipation channel 3 surrounds the hot steam pipe 1 and is installed in the exhaust box 2. The heat dissipation channel 3 connects the exhaust cavity 5 and the exhaust box 2, and is connected to the heat dissipation outlet. Figure 5 a is used to represent the distance between the hot steam outlet and the bottom surface of the exhaust box 2, b is used to represent the distance between the heat dissipation outlet and the bottom surface of the exhaust box 2, and c is used to represent the distance between the hot steam outlet and the exhaust grille outlet. It should be noted that the relationship between the three distances a, b, and c is as follows:

[0061] Among them, a is greater than b. Since the exhaust speed of hot steam is greater than the speed of heat dissipation airflow, the hot steam speed can be used to achieve the jet drainage effect, guiding the heat dissipation airflow to be discharged vertically upward from the heat dissipation outlet. c is greater than or equal to a. Only when there is enough distance left can the jet drainage effect of hot steam be better, and the airflow can be better dispersed in the exhaust cavity.
