Integrated cooking hob and heat dissipation exhaust structure thereof

Abstract

The present disclosure provides an integrated cooking range and its heat dissipation exhaust structure, wherein the heat dissipation exhaust structure of the integrated cooking range comprises a hot steam pipe, an exhaust box and a heat dissipation channel; the heat dissipation outlet of the heat dissipation channel and the hot steam outlet of the hot steam pipe are arranged inside the exhaust box; the heat dissipation outlet surrounds the hot steam pipe; the pipe diameter of the heat dissipation outlet is larger than that of the hot steam outlet. The heat dissipation channel structure 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 of the airflow direction makes the heat dissipation airflow not impact the exhaust cavity, avoiding the phenomenon that the airflow rotates in the cavity and reducing the vortex flow in the cavity. At the same time, since the directions of the two airflows are the same, the problem that the heat dissipation airflow acts as a wind curtain to hinder the hot steam from being discharged from the hot steam outlet is also eliminated.

Description

Technical Field

[0001] This disclosure relates to the field of integrated cooking stove technology, and in particular to an integrated cooking stove and its heat dissipation and exhaust structure. Background Technology

[0002] An integrated cooktop is a type of cooktop that combines a cooktop (primarily a gas stove) with cooking appliances (such as a steamer, oven, or steam-grill combination). Currently available integrated cooktop products contain heat-generating electronic components and a cooling system within the cooktop's internal cavity. See also Figure 1 The heat dissipation system includes heat dissipation channels (including heat dissipation channels 101 and 102) set in the inner cavity of the stove shell and a fan (including a fan impeller 103 and a volute 104) set in the heat dissipation channels. The cooking appliance has an internal exhaust port, and the discharged hot steam is connected to the exhaust box 106 through the hot steam pipe 105. Finally, it converges with the air blown out of the heat dissipation outlet 107 of the heat dissipation channel of the stove cavity in the exhaust chamber 108, and is discharged together from the exhaust grille 109 on the glass panel of the stove. However, the hot steam discharged from the cooking appliance such as the steam oven and the heat dissipation airflow in the stove cavity are discharged together, which causes some problems: the hot steam discharged from the cooking appliance (such as the steam oven) is vertically upward, while the air coming out of the heat dissipation channel of the stove cavity is horizontal. Moreover, the heat dissipation outlet is usually higher than the hot steam outlet. Therefore, the air coming out of the stove cavity will form an air curtain, which will hinder the discharge of hot steam and even cause backflow. In addition, since the gas discharged from the stove cavity is horizontal, the gas will first impact the wall of the exhaust cavity instead of being discharged vertically upwards. This causes the airflow to swirl inside the cavity, and the airflow to separate and form vortices, which affects the exhaust heat dissipation efficiency. Summary of the Invention

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

[0004] This disclosure solves the above-mentioned technical problems through the following technical solution:

[0005] This disclosure provides a heat dissipation and exhaust structure for an integrated cooking stove, the heat dissipation and exhaust structure of which includes: a hot steam pipe, an exhaust box, and a heat dissipation channel;

[0006] The heat dissipation outlet of the heat dissipation channel and the hot steam outlet of the hot steam pipe are located inside the exhaust box; the bottom cross-sectional area of ​​the heat dissipation channel inside the exhaust box is larger than the top cross-sectional area; the heat dissipation outlet surrounds the hot steam pipe; the diameter of the heat dissipation outlet is larger than the diameter of the hot steam outlet.

[0007] Preferably, the first distance is less than the second distance;

[0008] Wherein, 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.

[0009] Preferably, the heat dissipation and exhaust structure of the integrated cooking stove further includes an exhaust grille;

[0010] The exhaust grille and the exhaust box form an exhaust chamber;

[0011] The heat dissipation channel connects the exhaust chamber and the exhaust box.

[0012] Preferably, the second distance is less than or equal to the third distance;

[0013] Wherein, the second distance is the distance between the hot steam outlet and the bottom of the exhaust box, and the third distance is the distance between the hot steam outlet and the exhaust grille.

[0014] Preferably, the heat dissipation channel inside the exhaust box is truncated cone-shaped.

[0015] Preferably, one end of the heat dissipation inlet of the heat dissipation channel is connected to the fan; the other end of the heat dissipation inlet is connected to the heat dissipation outlet.

[0016] The fan is used to draw in airflow from the integrated cooking stove during operation and to discharge the airflow from the heat dissipation channel.

[0017] Preferably, the heat dissipation channel includes a first heat dissipation channel and a second heat dissipation channel;

[0018] The first heat dissipation channel and the second heat dissipation channel are arranged horizontally;

[0019] 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.

[0020] The fan is used to draw in airflow from the integrated cooking stove during operation and to discharge the airflow from the first heat dissipation channel and the second heat dissipation channel.

[0022] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this disclosure.

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

[0024] This disclosure utilizes a heat dissipation channel structure surrounding the hot steam pipe, with a bottom cross-sectional area larger than the top cross-sectional area, to change the airflow direction from horizontal to vertically upward when the cooling airflow exits the exhaust chamber. This change in airflow direction prevents the cooling airflow from impacting the exhaust chamber, avoiding airflow swirling within the chamber and reducing eddies. Simultaneously, because the two airflows are in the same direction, it also eliminates the problem of the cooling airflow acting as an air curtain, obstructing the exit of hot steam from the hot steam outlet.

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

[0032] The prefixes such as "first" and "second" used in this disclosure are merely for distinguishing different descriptive objects and do not limit the position, order, priority, quantity, or content of the described objects. The use of ordinal numbers and other prefixes used to distinguish descriptive objects in this disclosure does not constitute a limitation on the described objects. The description of the described objects is given in the claims or the context of the embodiments, and should not be construed as an unnecessary limitation. Furthermore, in the description of this embodiment, unless otherwise stated, "multiple" means two or more.

[0033] Example 1

[0034] The exhaust paths of integrated cooking products currently on the market are as follows: Figure 2As shown, solid arrows represent the direction of airflow for heat dissipation within the integrated cooking stove cavity, while dashed arrows represent the direction of hot steam emitted from cooking appliances such as steam ovens. When the fan inside the integrated cooking stove operates, the airflow within the cavity is drawn in by the negative pressure generated by the impeller at the inlet of the volute casing. After rotation, it is discharged from the outlet of the volute casing. The heat dissipation airflow flows through the heat dissipation channel and exits from the heat dissipation outlet to the exhaust chamber. Hot steam from the inner cavity of the cooking appliance is discharged from the exhaust port, flows through the hot steam pipe and exhaust box, and finally also exits into the exhaust chamber.

[0035] from Figure 3 As can be seen, because the cooling airflow is discharged horizontally into the exhaust chamber and its outlet position is higher than the hot steam outlet, it acts like an airflow curtain, hindering the vertical upward discharge of hot steam. Furthermore, the horizontal discharge of the cooling airflow impacts the inner wall of the exhaust chamber, causing it to swirl and generate eddies within the chamber.

[0036] This embodiment provides a heat dissipation and exhaust structure for an integrated cooking stove. By redesigning the exhaust path of the heat dissipation airflow and changing its exhaust direction, the mutual influence between the two airflows is eliminated, and the phenomenon of the heat dissipation airflow swirling is also eliminated.

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

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

[0039] In this embodiment, a heat dissipation channel structure surrounding the hot steam pipe, with a bottom cross-sectional area larger than the top cross-sectional area, causes the airflow direction to change from horizontal to vertically upward when the cooling airflow exits the exhaust chamber. This change in airflow direction prevents the cooling airflow from impacting the exhaust chamber, avoiding airflow swirling within the chamber and reducing eddies. Simultaneously, because the two airflows are in the same direction, the problem of the cooling airflow acting as an air curtain and obstructing the hot steam from the hot steam outlet is also eliminated.

[0040] In one alternative implementation, 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 frustum shape 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 inside the exhaust box, which has a large bottom cross-section and a small top cross-section, 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 velocity, thereby improving the efficiency and effect of exhaust heat dissipation.

[0042] In one alternative implementation, the first distance is less 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 hot steam outlet is located higher than the heat dissipation outlet, and the hot steam velocity is faster than the heat dissipation airflow velocity, a jet guiding effect is generated, which guides the heat dissipation airflow to be discharged vertically upward, thereby improving the overall exhaust heat dissipation efficiency of the integrated cooking stove.

[0045] In an optional implementation, 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 connects the exhaust chamber 5 and the exhaust box 2.

[0048] In one alternative 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 flow effect of the hot steam and allowing the heat dissipation airflow to dissipate heat better in the exhaust chamber.

[0051] In one alternative implementation, one end of the heat dissipation inlet of the heat dissipation channel is connected to a fan. The other end of the heat dissipation inlet is connected to a heat dissipation outlet.

[0052] The fan is used to draw in airflow from the integrated cooking stove during operation and expel the airflow through the heat dissipation channel.

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

[0054] The first and second heat dissipation channels are set 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 to draw in airflow from the integrated cooking stove during operation and to discharge the airflow from the first heat dissipation channel and the second heat dissipation channel.

[0057] In this embodiment, the heat dissipation channel can be integrally formed or divided into two parts. The fan blows air horizontally into the heat dissipation channel inside the exhaust box, which improves the heat dissipation efficiency.

[0058] The following is a specific example to illustrate the heat dissipation and exhaust structure of the integrated cooking stove in this embodiment.

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

[0060] The heat dissipation and exhaust structure includes an exhaust grille 4, an exhaust chamber 5, an exhaust box 2, a hot steam pipe 1, and a heat dissipation channel 3; the heat dissipation channel 3 includes a heat dissipation channel 501 inside the exhaust box. As can be seen in this example, the heat dissipation channel 501 inside the exhaust box is shaped like a frustum, 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 chamber 5 and the exhaust box 2, and is connected to the heat dissipation outlet. Figure 5 In this context, 'a' represents the distance between the hot steam outlet and the bottom surface of exhaust box 2, 'b' represents the distance between the heat dissipation outlet and the bottom surface of exhaust box 2, and 'c' represents the distance between the hot steam outlet and the exhaust grille outlet. The relationship between these three distances (a, b, and c) is as follows:

[0061] Where a is greater than b, since the exhaust velocity of hot steam is greater than the velocity of the cooling airflow, the velocity of the hot steam can be used to achieve a jet-guided flow effect, guiding the cooling airflow to exit vertically upward from the heat dissipation outlet. c is greater than or equal to a, only with sufficient remaining distance can the jet-guided flow effect of hot steam be better, and can the airflow be better dispersed in the exhaust chamber.
