DETAILED DESCRIPTION

[0029] The embodiments of the present application are described in detail below, and the embodiments are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout.

[0030] In the present application, unless otherwise explicitly specified and limited, the terms such as "assembly", "connection", "linkage" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrally connected; it can also be mechanical connection; it can be directly connected, or connected through an intermediate medium; it can be connected internally in two elements. The terms "upstream" and "downstream" should be defined in the direction of the air flow path, for example, upstream refers to the position close to the air source or the initial position in the air flow path, and downstream refers to the position close to the final flow direction or the position close to the air flow path. For those skilled in the art, the specific meaning of the above-mentioned terms in the present application can be understood according to the specific circumstances.

[0031] The technical scheme of the present application and its beneficial effects will be clearer and more explicit through the further description of the specific embodiments of the present application in combination with the drawings of the specification. The description of the embodiments by referring to the drawings is exemplary, and is intended to explain the present application, and cannot be understood as a limitation of the present application.

[0032] The preferred embodiment provided by the present application is as follows: Figures 1-9As shown, a cooking appliance comprises a housing 1, an inner container 2, a camera window 21 arranged on a side wall of the inner container 2, a mounting space 3 enclosed by the inner container 2 and the housing 1, and a camera assembly 4 arranged in the mounting space 3. The camera assembly 4 comprises a heat insulation cover 41, a heat dissipation fan 42, and a camera element 43. The heat insulation cover 41 is provided with an air inlet 411 and an air outlet 412. The heat dissipation fan 42 and the camera element 43 are arranged in the heat insulation cover 41. The air inlet 411 and the camera element 43 are arranged on the air inlet side and the air outlet side of the heat dissipation fan 42 respectively. The heat dissipation fan 42 draws air from the air inlet 411 and discharges the air to the camera element 43. The camera window 21 and the camera element 43 are located on the upper and lower sides of the air outlet 412 respectively, and the air outlet 412 is located on the circumferential side of the camera element 43. The camera element 43 is arranged opposite to the camera window 21. The air around the camera element 43 flows to the camera window 21 through the air outlet 412. The aforementioned air inlet side is the side of the heat dissipation fan 42 from which the heat dissipation fan 42 draws air from the air inlet 411. The air outlet side is the side of the heat dissipation fan 42 from which the heat dissipation fan 42 discharges the drawn air to the output end. The camera element 43 is on one side of the heat dissipation fan 42, and the aforementioned air outlet side is the side of the heat dissipation fan 42.

[0033] Reference cross-sectional view Figure 8 The aforementioned "up and down" is that, taking the air outlet 412 as a reference, the upstream side of the flow path of the air in the heat insulation cover 41 at the air outlet 412 is "up", and the downstream side of the aforementioned path is "down". The air first passes through the camera element 43 on the upper side of the air outlet 412, and then flows through the camera window 21 on the lower side of the air outlet 412. The camera element 43 is arranged on one side of the heat dissipation fan 42. The heat dissipation fan 42 draws air from the air inlet 411 and / or the mounting space 3, and discharges the air to the camera element 43. The air is discharged to the camera window 21 and / or the mounting space 3 through the air outlet 412.

[0034] In some optional embodiments, a fan is further arranged above the inner container 2. The fan draws air in the mounting space 3 and discharges the air to the outside to reduce the heat transferred from the inner container 2 to the housing 1, thereby avoiding the user from being scalded by mistakenly touching the housing 1. At this time, the air pressure in the mounting space 3 is less than the air pressure outside, and the air outside enters the mounting space 3 through the through hole of the housing 1 to balance the internal and external pressures. In the present embodiment, when the heat dissipation fan 42 draws air from the mounting space 3, since part of the air in the mounting space 3 is relatively low-temperature air from the outside, the heat dissipation fan 42 draws air from the mounting space 3 and discharges the air in the heat insulation cover 41 to the mounting space 3, which also achieves the purpose of dissipating heat from the camera element 43.

[0035] In the embodiment, the air passes through the air inlet 411, the heat dissipation fan 42, the camera component 43 and the air outlet 412 in sequence to form the first heat dissipation air duct 416. The heat dissipation fan 42 in the camera component 4 extracts the air in the installation space 3 from the air inlet 411, and the heat dissipation fan 42 delivers the air to the camera component 43 which needs to be cooled. Since the end of the camera component 43 is close to the air outlet 412, the air can directly take away the heat at the position of the camera component 43 to cool the camera component 43. The foregoing arrangement avoids the problem of air flow resistance caused by the trickle flow at the local position of the camera component 43 due to the complex structure inside the camera component 4, thereby avoiding the problem that the air cannot completely flow through the camera component 43, and further avoiding the problem that the heat in the camera component 43 cannot be completely taken away.

[0036] The specific installation position of the camera component 4 in the installation space 3 can be on the lining plate 32, or on the inner wall of the shell 1, or on the outer wall of the inner container 2. The shell 1 is arranged on one side of the inner container 2; the lining plate 32 is arranged above the inner container 2; and the camera component 4 is fixed on the shell 1 and / or the lining plate 32. The lining plate 32 has a gap with the inner container 2, the installation space 3 is the foregoing gap, and the camera component 4 is fixed on the lining plate 32; or, the shell 1 has a gap with the inner container 2, the installation space 3 is the foregoing gap, and the camera component 4 is fixed on the shell 1; or, the camera component 4 is fixed on the lining plate 32 and the shell 1 at the same time, and the space enclosed by the outer wall of the inner container 2, the lining plate 32 and the shell 1 is the installation space 3.

[0037] In the embodiment, the camera component 43 includes an element support 432, a circuit board 433 fixed on the element support 432, and a camera 431 protruding on the circuit board 433; the air outlet 412 is arranged on the circumferential side of the camera 431, or the air outlet 412 is arranged below the camera 431; and a gap for air flow is arranged between the camera 431 and the air outlet 412. The gap is used for discharging the hot air inside the heat shield 41. In this way, the heat at the end of the camera 431 can be taken away through the first heat dissipation air duct 416. In the embodiment, the air outlet 412 is arranged at the position of the camera 431, so that when the air is discharged, the end of the camera 431 is the place that the air must flow through, thereby solving the heat dissipation problem of the end of the camera 431. Since the camera window 21 can transmit the heat of the inner container 2 to the heat shield 41, in the embodiment, the camera window 21 is spaced apart from the heat shield 41 to form an air heat insulation layer between the camera window 21 and the heat shield 41, thereby reducing the heat received by the heat shield 41 / camera 431. At the same time, since the air outlet 412 can discharge the air towards the camera window 21, this can further reduce the temperature on the camera window 21 and increase the flow rate of the air in the foregoing air heat insulation layer to further reduce the heat of the air heat insulation layer, thereby reducing the heat that can be received by the camera 431.

[0038] Specifically, the following two implementations can be formed: ① the end of the camera 431 can be suspended above the exhaust port 412, and during the heat dissipation process, the air will pass through the end of the camera 431 and then be discharged from the exhaust port 412; ② the end of the camera 431 is embedded in the exhaust port 412, and during the heat dissipation process, the air will pass through the side wall close to the end of the camera 431 and then be discharged from the exhaust port 412, and at the same time, there is also partial air flowing through the end of the camera 431; at this time, the aperture of the exhaust port 412 needs to be greater than the diameter of the end of the camera 431.

[0039] In the embodiment, the heat shield 41 includes a vertical partition plate 413, which divides the inside of the camera assembly 4 into a first cavity 4131 and a second cavity 4132, and a first hole 4133 on the vertical partition plate 413 communicates the first cavity 4131 and the second cavity 4132; the heat dissipation fan 42 is arranged in the first cavity 4131, and the camera element 43 is arranged in the second cavity 4132. The vertical partition plate 413 is used to separate the heat dissipation fan 42 and the camera element 43. The heat dissipation fan 42 can be an axial fan, a centrifugal fan, etc. In the preferred embodiment, the heat dissipation fan 42 adopts a volute type centrifugal fan. The volute type centrifugal fan can make the airflow direction of both ends of the fan vertical, i.e., the air inlet direction and the air outlet direction of the fan are vertical. Such arrangement can reduce the overall thickness of the heat shield 41, facilitating assembly in the narrow installation space 3. The arrangement of the vertical partition plate 413 also reduces the air flow interference in the first cavity 4131 and the second cavity 4132, avoiding that the air not discharged from the exhaust port 412 in the heat shield 41 is sucked back by the heat dissipation fan 42 during the air inlet process of the heat dissipation fan 42, thereby improving the efficiency of the heat dissipation fan 42. At this time, the specific path of air flow in the first heat dissipation air duct 416 is: the air inlet 411→the heat dissipation fan 42 in the first cavity 4131→the first hole 4133→the camera element 43 in the second cavity 4132→the exhaust port 412.

[0040] Specifically, the heat shield 41 is in a box-shaped structure to reduce the influence of heat in the installation space 3 on the camera element 43; the heat dissipation fan 42 and the camera element 43 are both arranged in the heat shield 41, and part of the heat in the installation space 3 is isolated outside the heat shield 41; in this way, the heat insulation structure can wrap most of the structure of the camera element 43, thereby reducing the influence of external heat on the camera element 43. The heat shield 41 can be fixed under the lining plate 32 by fasteners, or fixed on the inner side of the shell 1 by fasteners, or fixed on the outer side wall of the inner container 2 by fasteners. The fasteners can be screws, nails, clamps, etc., which are the selection of conventional technical means and will not be described here.

[0041] In the embodiment, the heat shield 41 further comprises a transverse partition plate 414 and a fourth hole 4141; the transverse partition plate 414 is vertically arranged on one side of the vertical partition plate 413; the fourth hole 4141 is arranged on the transverse partition plate 414; the transverse partition plate 414 divides the second cavity 4132 into an element upper cavity 4142 and an element lower cavity 4143 which can communicate with the element upper cavity 4142; the element lower cavity 4143 communicates with the element upper cavity 4142 through the fourth hole 4141; the camera element 43 is arranged in the fourth hole 4141. Since the camera element 43 is arranged in the fourth hole 4141, the position of the camera element 43 spans the element upper cavity 4142 and the element lower cavity 4143. The transverse partition plate 414 is arranged at the bottom of the first hole 4133, and the transverse partition plate 414 can guide the air discharged by the heat dissipation fan 42 to the second cavity 4132. The transverse partition plate 414 divides the second cavity 4132 into the element upper cavity 4142 and the element lower cavity 4143, and since the camera element 43 spans the element upper cavity 4142 and the element lower cavity 4143, the air discharged by the heat dissipation fan 42 to the second cavity 4132 can enter the element upper cavity 4142 and the element lower cavity 4143 respectively, that is, the camera element 43 in the element upper cavity 4142 and the element lower cavity 4143 can be cooled at the same time. At this time, the air forms two flow paths in the first heat dissipation air duct 416: path 1: air inlet 411→heat dissipation fan 42 in the first cavity 4131→first hole 4133→camera element 43 in the element upper cavity 4142 of the second cavity 4132→air outlet 412; path 2: air inlet 411→heat dissipation fan 42 in the first cavity 4131→first hole 4133→camera element 43 in the element lower cavity 4143 of the second cavity 4132→air outlet 412.

[0042] In the embodiment, the camera window 21 comprises a mounting hole 211, a mounting bracket 212 and heat insulation glass 213; the mounting bracket 212 is embedded in the mounting hole 211 and fixed on the inner container 2; the heat insulation glass 213 is fixed on the mounting bracket 212. The mounting bracket 212 is attached to the outer side wall of the inner container 2; the mounting bracket 212 has a through hole in the middle which matches the mounting hole 211, and a sunken step structure is formed at the edge of the through hole; the heat insulation glass 213 is installed on the step structure. The heat insulation glass 213 here can be single-layer glass or multi-layer glass. The specific number of layers is determined according to the heat transfer performance of the heat insulation glass 213 and the heat dissipation performance of other structures. The fixed connection between the heat insulation glass 213 and the mounting bracket 212 is a conventional technical means, which can be adhesive, clamping, etc.; and the mounting method of the inner container 2 and the mounting bracket 212 is a conventional technical means, which can be adhesive, clamping, rivets, welding, etc., which will not be described here.

[0043] In some alternative embodiments, the inner container 2 is formed with a sunken step structure at the position of the mounting hole 211 to mount the heat insulation glass 213. In this embodiment, the mounting structure of the mounting bracket 212 is formed on the inner container 2 by a stamping forming process, i.e., the mounting hole 211 and the mounting bracket 212 of the inner container 2 are combined into one. At this time, the mounting bracket 212 that can mount the heat insulation glass 213 is formed on the inner container 2, and the image information inside the inner container 2 can be received by the camera element 43 through the middle hollow structure of the mounting bracket 212.

[0044] In this embodiment, the camera 431 is electrically connected with the circuit board 433, and the end plane of the camera 431 is parallel to the plane where the heat insulation glass 213 is located. The element bracket 432 is arranged parallel to the circuit board 433. The camera element 43 further comprises a support column 434, the circuit board 433 is fixed on the element bracket 432 through the support column 434, and a gap is arranged between the circuit board 433 and the element bracket 432; the camera 431 and the element bracket 432 are arranged on the same side of the circuit board 433. The gap between the element bracket 432 and the circuit board 433 is formed by the support column 434, and the arrangement makes air pass through on both sides of the circuit board 433, so that the heat dissipation of both sides of the circuit board 433 can be realized. Since the camera 431 is integrated on the circuit board 433, the camera 431 is vertically arranged on the circuit board 433 at this time; the element bracket 432 is arranged on the side close to the camera 431, and the element bracket 432 is provided with an avoiding hole through which the camera 431 is arranged. The camera 431 and the element bracket 432 are arranged on the same side to reduce the influence of the support column 434, avoid increasing the thickness of the camera element 43, and thus realize the lightness and thinness of the heat insulation cover 41. Of course, the camera 431 and the circuit board 433 can also be arranged in a split type, and the camera 431 is electrically connected with the circuit board 433 through a flexible flat cable; at this time, it is only necessary to ensure that the camera 431 is arranged at the air outlet 412, and the position of the circuit board 433 can not necessarily be arranged close to the camera 431.

[0045] The purpose of the parallel arrangement of the end plane of the camera 431 and the heat insulation glass 213 is to avoid the refraction deformation of the image information received by the camera 431 on the heat insulation glass 213 when the heat insulation glass 213 and the end plane of the camera 431 form an included angle; the parallel arrangement of the end plane of the camera 431 and the heat insulation glass 213 can effectively reduce the deformation of the image.

[0046] In the embodiment, the heat insulation glass 213 and the heat insulation cover 41 have a gap to form the second heat dissipation air duct 31; the exhaust port 412 of the heat insulation cover 41 communicates with the second heat dissipation air duct 31. In the prior art, the end of the camera 431 abuts against the camera window 21, and the camera window 21 transmits heat inside the cooking cavity to the camera 431, thereby increasing the temperature of the working environment of the camera 431, and the camera 431 is prone to reduced service life or abnormal work due to high temperature. In the embodiment, the second heat dissipation air duct 31 is arranged between the heat insulation glass 213 and the heat insulation cover 41; the arrangement enables the air discharged at the exhaust port 412 of the heat insulation cover 41 to flow through the heat insulation glass 213, thereby dissipating heat of the heat insulation glass 213 to reduce the temperature of the surface of the heat insulation glass 213, and further reducing the heat transmitted from the heat insulation glass 213 to the camera 431, optimizing the working environment of the camera 431, and improving the stability of the camera 431 during work.

[0047] In the embodiment, the inner container 2 has a cross section in the shape of a rounded rectangle, and the camera window 21 is arranged at an arc surface position on the top edge of the inner container 2. The camera element 43 collects image information inside the inner container 2 through the camera window 21. Due to the limitation of the height of the inner container 2 and the limited range of the image that can be collected by the camera element 43, the camera element 43 needs to be arranged as close as possible to the top wall of the inner container 2 and needs to be arranged centrally to ensure the symmetry of the image; and generally, the top wall of the inner container 2 is provided with a heating tube or a heat circulation fan, and at this time, the structure of the top wall hinders the installation of the camera assembly 4, and the heating tube blocks the camera 431 or interferes with the collection of image information. Therefore, the camera window 21 is arranged at a position on the top wall of the inner container 2 and close to the middle area of the side wall of the inner container 2, and at this time, the camera window 21 is in an inclined state relative to the top wall of the inner container 2, and the camera element 43 faces the cooking cavity of the inner container 2. The end of the camera 431 needs to be parallel to the heat insulation glass 213; the camera 431 also needs to be arranged in an inclined state synchronously with the camera window 21. The camera 431 can shoot the image of the food in the inner container 2 more stereoscopically. Specifically, the heat insulation cover 41 is also arranged in an inclined state with the camera window 21. In an optional embodiment, due to the limitation of the space and the fixed structure of the specific installation position of the camera assembly 4, the element support 432 is arranged in a plate-shaped structure, and the camera 431 fixed on the element support 432 is also in an inclined state by arranging the element support 432 in an inclined state. In order to enable the camera 431 to effectively collect image information in the cooking cavity of the inner container 2, the specification of the camera 431 can be selected as follows: the aperture is 2.4-2.6, the effective focal length is 2.02 mm-2.9 mm, and the field of view angle is diagonal 105°-160°.

[0048] In some alternative embodiments, the support structure in the heat shield 41 cannot be inclined due to the limitation of the mold releasing process; in this case, the element holder 432 is arranged in a V-shaped structure, one segment of the element holder 432 is fixed in the heat shield 41, and the other segment of the element holder 432 is arranged in a relatively inclined state; in this way, the camera element 43 fixed on the element holder 432 is also arranged in an inclined state relative to the inner container 2. In addition, in other alternative embodiments, the side of the heat shield 41 is in the shape of a right-angled trapezoid, the inclined side of the aforementioned right-angled trapezoid corresponds to a plane facing the camera window 21; the heat dissipation fan 42 is arranged vertically, and the camera element 43 is arranged towards the aforementioned plane.

[0049] In the present embodiment, the heat shield 41 further comprises a second hole 4134 and a third hole 415; the second hole 4134 is arranged on the vertical partition 413 in the element lower cavity 4143; the third hole 415 is arranged on the side wall of the heat shield 41; the air in the element lower cavity 4143 is discharged by the heat dissipation fan 42 through the second hole 4134 into the first cavity 4131, and then discharged to the mounting space 3 and / or the outside through the third hole 415. The air discharged by the heat dissipation fan 42 sequentially passes through the element lower cavity 4143 of the second cavity 4132, the second hole 4134 of the vertical partition 413, the first cavity 4131, and the third hole 415 of the side wall of the heat shield 41 to form a third heat dissipation air duct 417. The leads of the camera element 43 extend to the outside of the heat shield 41 through the second hole 4134 and the third hole 415 in the second cavity 4132 to connect with the control unit; the leads of the heat dissipation fan 42 extend to the outside of the heat shield 41 through the third hole 415 to connect with the control unit. In the present embodiment, the air flow directions between the first cavity 4131 and the second cavity 4132 are both unidirectional. The air in the first cavity 4131 enters the second cavity 4132 through the first hole 4133 by the heat dissipation fan 42; the air in the second cavity 4132 enters the first cavity 4131 through the second hole 4134 by the heat dissipation fan 42. The two air flow paths do not interfere with each other. Under the air flow in the third heat dissipation air duct 417, the heat on the aforementioned leads is discharged to the outside of the heat shield 41 through the third hole 415, thereby reducing the influence of temperature on the leads and improving the stability of the signal transmission of the camera element 43.

[0050] Specifically, the heat dissipation fan 42 is a volute centrifugal fan; the heat dissipation fan 42 is arranged at a middle position of the first cavity 4131; a gap is arranged between the back of the heat dissipation fan 42 and the heat shield 41; the lead wires of the camera element 43 and the lead wires of the heat dissipation fan 42 extend to outside the heat shield 41 through the gap and the third hole 415; the second hole 4134 and the third hole 415 are arranged at two ends of the gap respectively. Specifically, air forms a flow path in the third heat dissipation air duct 417: the element lower cavity 4143 of the second cavity 4132→the second hole 4134→the gap of the first cavity 4131→the third hole 415.

[0051] In the embodiment, the air inlet 411 communicates with the outside through a through hole on the shell 1; the through hole can be a matrix type round hole or a fence type through hole. Further, the air inlet 411 can directly abut the position of the through hole of the shell 1, or the air inlet 411 can be arranged with a gap with the shell 1. When the air inlet 411 has a gap with the shell 1, the air extracted by the heat dissipation fan 42 from the air inlet 411 can be the air in the installation space 3 or the outside air entering from the through hole of the shell 1. The communication form of the through hole and the air inlet 411 is various, which can be realized by abutting the air inlet 411 to the through hole, or realized by connecting the air inlet 411 and the through hole through a tubular connecting piece.

[0052] In some optional embodiments, the shell 1 is provided with a groove type handle 11, the inner side of the handle 11 has a through hole, and the outside air enters the installation space 3 and / or the air inlet 411 through the through hole. The communication form of the through hole and the air inlet 411 is various, which can be realized by abutting the air inlet 411 to the through hole, or realized by connecting the air inlet 411 and the through hole through a tubular connecting piece. When the present scheme is applied to the product of the embedded oven, the distance between the shell 1 and the wall / cabinet side wall is too close, and the heat dissipation fan 42 may not be able to form sufficient negative pressure to draw the outside air; at this time, when the air inlet through hole is arranged inside the groove type handle 11, a relatively large negative pressure area can be formed in the handle 11 under the action of the heat dissipation fan 42, and the area of the negative pressure area will be larger than the area of the through hole, so that more air near the handle 11 can be adsorbed.
