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 (including fan impeller 103 and 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 stove cavity 701 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 defects in the prior art that when the hot steam discharged from the cooking device is discharged together with the heat dissipation airflow in the stove cavity, the hot steam is difficult to be discharged, the heat dissipation airflow forms a vortex, and the exhaust heat dissipation efficiency is affected, and an integrated cooking stove and its heat dissipation exhaust structure are provided.

[0034] The present disclosure is further described below by way of examples, but the present disclosure is not limited to the scope of the examples.

[0035] 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.

[0036] Example 1

[0037] The exhaust paths of integrated cooking products currently on the market are as follows: Figure 2 As 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.

[0038] 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 heat dissipation airflow discharged horizontally will impact the inner wall of the exhaust cavity, swirl in the exhaust cavity, and generate vortices.

[0039] 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.

[0040] See also Figure 4 The heat dissipation and exhaust structure of the integrated cooking stove includes an exhaust grille 1, a hot steam pipe 2, an exhaust box 3 and a heat dissipation channel 4.

[0041] The exhaust grille 1 and the exhaust box 3 form an inverted Type exhaust cavity 5.

[0042] The hot steam outlet of the hot steam pipe 2 is arranged in the exhaust box 3.

[0043] The heat dissipation outlet of the heat dissipation channel 4 is arranged on the flange walls extending on both sides of the exhaust cavity 5 .

[0044] The heat dissipation outlet is arranged in parallel with the hot steam outlet.

[0045] This embodiment is reversed The exhaust cavity is designed in such a way that the heat dissipation outlets originally on the inner wall of the exhaust cavity are arranged on the flange walls expanded on both sides of the exhaust cavity, so that after the heat dissipation airflow flows through the heat dissipation channel, the airflow discharge direction is changed from the original horizontal direction to the vertical upward direction, thereby changing the airflow direction of the heat dissipation airflow entering the exhaust cavity, eliminating the hidden danger of the heat dissipation airflow hindering the discharge of hot steam, and improving the phenomenon that the heat dissipation airflow rotates in the exhaust cavity to form a vortex, thereby improving the overall exhaust heat dissipation efficiency.

[0046] In an optional implementation, the heat dissipation channel is an L-shaped heat dissipation channel 4 .

[0047] like Figure 1 As shown, the existing heat dissipation channel is usually "Z-shaped", and the heat dissipation airflow exhaust direction is horizontal. However, this embodiment sets the heat dissipation channel to an L-shaped heat dissipation channel, changes the airflow direction of the heat dissipation airflow entering the exhaust cavity, and changes the heat dissipation airflow exhaust direction from the original horizontal direction to a vertical upward direction, thereby eliminating the hidden danger of the heat dissipation airflow hindering the discharge of hot steam.

[0048] In an optional embodiment, the heat dissipation outlet is located higher than the hot steam outlet.

[0049] In this embodiment, since the heat dissipation outlet is located higher than the hot steam outlet, the problem of the heat dissipation airflow acting as an air curtain to hinder the discharge of hot steam is eliminated, thereby further improving the exhaust heat dissipation efficiency.

[0050] Figure 5 The heat dissipation exhaust structure of this embodiment is schematically shown. It can be seen that the exhaust cavity 5 of the heat dissipation exhaust structure has a shape similar to an "inverted " type, the heat dissipation outlet 501 originally on the inner wall of the exhaust cavity 5 is set on the flange walls expanded on both sides of the exhaust cavity 5. At the same time, the "Z-shaped" heat dissipation channel 4 originally connected to the exhaust cavity 5 is designed to be similar to an "L-shaped" channel. In this way, after the heat dissipation airflow flows through the heat dissipation channel 4, the airflow discharge direction changes from the original horizontal direction to the vertical upward direction.

[0051] Example 2

[0052] This embodiment provides another integrated cooking stove heat dissipation exhaust structure, see Figure 6 The heat dissipation and exhaust structure of the integrated cooking stove includes: an exhaust box 3, a hot steam pipe 2 and a heat dissipation channel 4.

[0053] The exhaust box 3 includes a first box body, a second box body and a partition 601. The first box body is separated from the second box body by the partition 601.

[0054] The heat dissipation outlet of the heat dissipation channel 4 is arranged in the first box body. The hot steam outlet of the hot steam pipe 2 is arranged in the second box body.

[0055] See also Figure 6In this embodiment, a partition 601 is provided in the exhaust box 3 to isolate the heat dissipation airflow and the hot steam, thereby forming two exhaust chambers. The two airflows do not interfere with each other, and the exhaust heat dissipation efficiency is also improved.

[0056] In an optional embodiment, the heat dissipation channel includes a first heat dissipation channel and a second heat dissipation channel.

[0057] 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.

[0058] The cross section of the first heat dissipation channel gradually decreases along the first direction.

[0059] The first direction is from the heat dissipation inlet of the first heat dissipation channel to the heat dissipation outlet of the first heat dissipation channel. The fan is used to inhale the airflow in the integrated cooking stove and discharge the airflow from the first heat dissipation channel and the second heat dissipation channel when in operation.

[0060] In this embodiment, the diameter of the first heat dissipation channel connected to the fan is gradually reduced to accelerate the discharge efficiency of the heat dissipation airflow, thereby improving the heat dissipation efficiency.

[0061] In an optional embodiment, the cross section of the heat dissipation inlet of the first heat dissipation channel is rectangular. Because the outlet of the fan is usually rectangular, setting the cross section of the heat dissipation inlet of the first heat dissipation channel to be rectangular can better match the shape of the fan outlet, making the heat dissipation airflow discharge smoother.

[0062] In an optional embodiment, the cross-section of the heat dissipation outlet of the first heat dissipation channel and the heat dissipation inlet of the second heat dissipation channel are circular, thereby improving the climbing effect of the heat dissipation gas.

[0063] In an optional embodiment, the heat dissipation outlet is arranged in parallel with the hot steam outlet, thereby ensuring that the direction of the heat dissipation airflow entering the exhaust cavity is the same as the direction of the hot steam entering the exhaust cavity, eliminating the existence of vortices in the cavity and improving the exhaust heat dissipation effect.

[0064] In an optional embodiment, the diameter of the heat dissipation outlet is the same as the diameter of the hot steam outlet, so that the shape of the exhaust box is more beautiful.

[0065] Figure 7This is a schematic diagram of the heat dissipation and exhaust structure of this embodiment. It can be seen that the heat dissipation inlet 7011 of the first heat dissipation channel is rectangular, the heat dissipation outlet 7012 of the first heat dissipation channel is circular, and the pipe diameter of the first heat dissipation channel 701 gradually shrinks. The heat dissipation outlet 7012 of the first heat dissipation channel is connected to the heat dissipation inlet of the second heat dissipation channel 702, and the heat dissipation outlet 501 and the heat dissipation inlet of the second heat dissipation channel are both set to be circular, and the heat dissipation outlet 501 of the second heat dissipation channel is set in the exhaust box 3. The exhaust cavity 5 and the exhaust box 3 are designed to have two outlets, separated by a partition 601 in the middle, and are respectively connected to the heat dissipation outlet 501 of the second heat dissipation channel and the hot steam outlet of the hot steam pipe. The heat dissipation outlet 501 of the second heat dissipation channel and the hot steam outlet have the same pipe diameter.
