Description

Technical Field

[0001] The invention relates to a door for household appliances. Background Art

[0002] Household appliances such as cooking equipment, refrigerators, and clothes processing devices that contain objects in an internal space and have doors are widely used. Such household appliances may include a storage space for containing objects inside a box forming an appearance and a door for opening and closing the storage space. Such household appliances may also include more than two storage spaces and more than two doors for opening and closing each storage space, depending on the situation.

[0003] Generally, the door of a household appliance is made opaque. Therefore, when the door closes the storage space, it is difficult for a user to confirm the object stored in the storage space. In a household appliance having such a door, in order to confirm the object stored in the storage space, the door needs to be opened.

[0004] However, in the case of household appliances such as refrigerators, ovens, and dryers, when the door is opened, cold air or hot air inside the household appliance flows out to the outside, thereby possibly generating unnecessary energy loss. In addition, in the case of household appliances such as washing machines, when the door is opened, washing water may flow out to the outside. Therefore, the door of the washing machine during the washing operation is kept locked to prevent the door from being opened at will during the washing operation.

[0005] On the other hand, a see-through window is sometimes installed on the door of some household appliances such as cooking equipment, washing machines, and dryers. If a see-through window is installed on the door as described above, the state of the object inside the household appliance can be confirmed through the see-through window. However, even if a see-through window is installed on the door of the household appliance, it is difficult to normally confirm the object if the surroundings of the household appliance are dark or at night.

[0006] Therefore, recently, not only a door with a see-through window is installed, but also a camera for photographing the interior of the storage space containing the object is installed. Even in a state where the door is closed, the camera can photograph the interior of the storage space and provide the photographed image to the user. However, in the case of a cooking device, the interior of the storage space is an environment with a very high temperature, and in the case of a washing machine or a dryer, the interior of the storage space is an environment with a very high humidity, so the camera device may be easily damaged.

[0007] For this purpose, a camera may be installed inside the door of the oven. However, generally, the interior of the cooking device cannot ensure sufficient light to capture images, so it is difficult for the camera device installed on the door to provide a clear image to the user. In particular, the above-mentioned camera device needs to capture images through at least one panel (glass, etc.) constituting the door, so there is a problem that it is more difficult to obtain sufficient light.

[0008] In addition, when the user observes the inside of the cooking device through the transparent door, there is a problem that the camera device installed inside the door blocks the user's field of vision. In particular, when the door is made transparent, the camera device is exposed to the outside, thereby damaging the aesthetics of the cooking device. Summary of the invention

[0009] The present invention is used to solve the problems of the prior art as described above. The purpose of the present invention is to capture an image of a storage space in a state where the illuminance of the storage space is improved by configuring an image sensing device and a lighting device on the door of a household appliance.

[0010] Another object of the present invention is to configure an image sensing device and a lighting device inside a door of a household appliance and capture an image of a storage space.

[0011] Another object of the present invention is to store the image sensing device inside a transparent door of a household appliance without exposing the image sensing device to the outside and to prevent the image sensing device from blocking the user's field of vision.

[0012] Another object of the present invention is to additionally configure an image acquisition module inside the door without changing the design of the door of the existing household appliance.

[0013] Still another object of the present invention is to easily install an image sensing device and a lighting device inside a door of a home appliance.

[0014] Still another object of the present invention is to make the illumination inside the storage space uniform by effectively disposing a lighting device inside the door.

[0015] According to the features of the present invention for achieving the above-mentioned purpose, the present invention may include a door body arranged in front of a storage space of a household appliance. An image acquisition module facing the storage space may be arranged on the door body. In this case, the image acquisition module may include an image sensing device for acquiring an image of the storage space and an illumination device for irradiating light to the storage space. Thus, an image of the storage space can be captured in a state where the illumination of the storage space is increased, and a user can obtain a clearer image of a subject stored inside the storage space.

[0016] The image acquisition module may be disposed on a surface of the door body facing the storage space, thereby a larger surface of the door body may be used as an installation space for the image acquisition module.

[0017] The image acquisition module may be disposed inside a door frame constituting the door body. The image acquisition module disposed inside the door frame may not be directly exposed to the storage space.

[0018] The door frame may be combined with a door panel including a plurality of panels. The door frame may be formed with a perspective portion through which the storage space is viewed through the through portion.

It should be noted that when assigning reference numerals to the constituent elements of each drawing, the same reference numerals are assigned to the same constituent elements as much as possible even if they are shown in different drawings. In addition, in the process of describing the embodiments of the present invention, when it is determined that the specific description of the relevant known structure or function will hinder the understanding of the embodiments of the present invention, the detailed description thereof is omitted.

[0196] The present invention relates to a door for a household appliance (hereinafter referred to as a "door"). Here, the household appliance may refer to an appliance having a storage space inside. The door is arranged in front of the storage space and can play a role in opening and closing the storage space. Here, the front refers to the direction toward the user when the user is in front of the household appliance. Figure 1 , the X-axis direction may be the front. The Y-axis direction may be the width direction of the door 50, 70. The Z-axis direction may be the height direction of the door 50, 70. The following description will be based on these directions.

[0197] The household appliance door can be applied not only to doors 50 and 70 of household appliances such as cooking equipment, refrigerators, freezers, kimchi refrigerators, plant cultivation devices, clothing care machines, and washing machines, but also to doors of furniture or entrance doors.

[0198] In this embodiment, the door is composed of two doors 50, 70, but it can also be applied to a household appliance having only one lower door 70. Hereinafter, the two doors 50, 70 of the present invention are applied to a cooking device as an example for description. In addition, the door disposed at the relatively upper part of the two doors 50, 70 is referred to as the upper door 50, and the door disposed at the lower part is referred to as the lower door 70.

[0199] In this embodiment, the door 50, 70 not only opens and closes the storage space 31, 41 of the household appliance, but also can use the image acquisition module 100 to acquire the internal image of the storage space 31, 41. In addition, the door 50, 70 can improve the internal illumination of the storage space 31, 41. To this end, the image acquisition module 100 may include an image sensing device 170 and a lighting device 180. The image acquisition module 100 may be disposed inside the door 50, 70. The door 50, 70 will be described below with the image acquisition module 100 as the center.

[0200] Reference Figure 1 , shows a cooking device to which the doors 50, 70 are applied. The main body 10 of the cooking device may have a substantially hexahedral shape. In this embodiment, the main body 10 of the cooking device may include two doors 50, 70. The two doors 50, 70 may be configured to have different heights from each other. The two doors 50, 70 may respectively shield different storage spaces 31, 41.

[0201] Reference Figure 2 , showing a situation where the side cover 12 constituting the main body 10 of the cooking device is separated. Two boxes 30, 40 may be arranged at different heights in the internal space 13. Storage spaces 31, 41 separated from each other may be provided in the two boxes 30, 40, respectively. As another example, only one box may be provided in the internal space 13, or more than three boxes 30, 40 may be provided. As yet another example, the two boxes 30, 40 may also be arranged on the left and right. Reference numeral 11 indicates a back cover constituting the main body 10 of the cooking device.

[0202] An upper panel 15 may be provided on the upper part of the cooking device. An operation unit 16 may be provided on the upper panel 15. The operation unit 16 may be used to operate the functions of the cooking device and to display the status of the cooking device. The upper panel 15 and the upper door 50 may be separated. A panel separation space D1 may be formed between the upper panel 15 and the upper door 50. External air may flow in through the panel separation space D1, or air inside the upper door 50 may be discharged through the panel separation space D1.

[0203] A main conductor W1 may be connected to the upper panel 15. The main conductor W1 may connect the operation unit 16 and a main control unit described later. Alternatively, the main conductor W1 may also connect the operation unit 16 and the image acquisition module 100. The main conductor W1 may also be connected to a connecting conductor W2 described later by means of a connector module 200.

[0204] The two boxes 30 and 40 can be divided into a first box 30 and a second box 40. The first box 30 and the second box 40 can be arranged at different heights in the internal space 13. An upper storage space 31 can be provided inside the first box 30, and a lower storage space 41 can be provided inside the second box 40.

[0205] The first cabinet 30 and the second cabinet 40 may have cooking structures in different ways. For example, the first cabinet 30 may have only one heat source, while the second cabinet 40 may have a plurality of heat sources. As another example, the first cabinet 30 may generate microwaves to cook the food F, while the second cabinet 40 may include a convection heater or an induction heating heat source.

[0206] An upper door 50 may be disposed in front of the first box body 30, and a lower door 70 may be disposed in front of the second box body 40. In this embodiment, the upper door 50 and the lower door 70 may be respectively operated in a pull-down manner, that is, the upper end rotates up and down with the lower end as the center. As another example, the upper door 50 and the lower door 70 may also be respectively operated in a lateral swing manner to open sideways.

[0207] Observing the upper door 50, the front face 51 of the upper door 50 may have a structure that allows the upper storage space 31 to be seen through. For example, the front face 51 of the upper door 50 has a panel structure of glass material, so that the user can observe the interior of the upper storage space 31 through the upper door 50. As another example, the front face 51 of the upper door 50 may also be made of a dark material, or coated with an additional film, so that the upper storage space 31 cannot be seen through from the outside. Reference numeral 55 indicates an upper handle 55 for opening and closing the upper door 50.

[0208] The lower door 70 may be disposed at the lower part of the upper door 50. The lower door 70 may be disposed in front of the second box body 40. The lower storage space 41 may be seen through the front of the lower door 70. The user may observe the interior of the lower storage space 41 through the front of the lower door 70.

[0209] Reference Figure 1 A door-separated space D2 may be formed between the upper door 50 and the lower door 70. The door-separated space D2 is a space formed by separating the upper end of the lower door 70 and the lower end of the upper door 50 from each other. Through the door-separated space D2, external air may flow toward the main body 10 of the cooking device, or conversely, the internal air passing through the lower door 70 may be discharged to the outside.

[0210] In the present embodiment, a perspective portion V may be provided in the lower door 70. The perspective portion V is used to see through the lower storage space 41 from the outside, and may be made of a transparent material. The perspective portion V may also be regarded as a part of the second front panel G2a constituting the front of the lower door 70. The perspective portion V may be provided at the center of the second front panel G2a. For example, the edge portion of the second front panel G2a may have a material with a large surface roughness different from the perspective portion V, or an additional opaque film may be applied to the edge portion of the second front panel G2a. Thus, except for the perspective portion V, the edge portion of the second front panel G2a cannot see through the lower storage space 41.

[0211] As another example, the edge of the second front panel G2a corresponding to the outer side of the perspective portion V may also be blocked by the door frames 72, 77, 80, 90. Here, the outer side of the perspective portion V may refer to the edge portion of the second front panel G2a arranged to surround the edge of the perspective portion V with the perspective portion V as the center.

[0212] As another example, the lower door 70 may be made of a dark material or coated with an additional film so that the lower storage space 41 cannot be seen from the outside. As another example, the lower door 70 may have an opaque metal or non-metal plate as the front surface, and the lower door panel G2 described later may be omitted. In this case, the lower storage space 41 may also not be seen from the outside.

[0213] Reference Figure 2 , showing a state where the image acquisition module 100 and the connector module 200 are installed inside the lower door 70. Figure 2 1 and 2. The image acquisition module 100 and the connector module 200 are shown in the figure, but the image acquisition module 100 and the connector module 200 may not be visible from the front of the cooking device. This is because, as described above, the edge portion of the second front panel G2a is not transparent except for the perspective portion V. Reference numeral 75 denotes a lower handle 75 for opening and closing the lower door 70.

[0214] Figure 3 is a cross-sectional view showing the interior of an embodiment of the present invention. Figure 3The upper door 50, the lower door 70 and the internal structure of the cooking device are shown. A plurality of spaces may be provided inside the cooking device. A machine room S1 may be provided at the upper part of the cooking device. Control units 21 and 22 may be provided in the machine room S1. A separate upper heat-insulating space S2 separated from the machine room S1 may be provided at the lower part of the machine room S1. In addition, an additional control unit 23 may also be provided at the rear of the cooking device.

[0215] A heating device 35, 45, 46 may be disposed behind the cooking device and inside the cavity 30, 40. The heating devices 35, 45, 46 may heat the upper storage space 31 and the lower storage space 41. An upper motor 24 and an upper fan 25 may be disposed behind the upper storage space 31. The upper motor 24 and the upper fan 25 may discharge air into the upper storage space 31 to allow air convection inside the upper storage space 31. Reference numeral 38 indicates a tray disposed in the upper storage space 31.

[0216] A lower motor 47 and a lower fan (not shown) may be disposed at the rear of the cooking device. The lower motor 47 and the lower fan (not shown) may discharge air into the lower storage space 41 to allow air convection in the lower storage space 41. When the second heat source 45 disposed at the upper portion of the lower storage space 41 heats the lower storage space 41, the lower motor 47 and the lower fan may circulate the heated air.

[0217] In this embodiment, a third heat source 46 may be further provided in the lower storage space 41. The third heat source 46 may be arranged in front of the lower fan. The third heat source 46 may quickly increase the temperature inside the lower storage space 41 together with the second heat source 45.

[0218] A cooling fan CF may be provided inside the main body 10 of the cooking device. The cooling fan CF may circulate air inside the machine room S1 to cool the cooking device. The cooling fan CF may be disposed at the rear of the machine room S1.

[0219] The cooling fan CF may also circulate air into the interior of the upper door 50 and the interior of the lower door 70. The cooling fan CF allows external air to flow in through the flow path inlet I at the lower side of the lower door 70 and then pass through the lower door 70 and the upper door 50 in sequence, thereby cooling the upper door 50 and the lower door 70. Fig. 22An air guide G may be provided below the lower door 70 , and a flow path inlet I for the external air to flow in may be formed in the air guide G. Reference numeral 73 denotes a bracket provided at the lower end of the front frame portion 72 for mounting the air guide G.

[0220] More specifically, the cooling fan CF can be operated to draw in external air from the flow path inlet I located at the lower side of the lower door 70 (arrow ① direction). The drawn external air can rise along the second cooling flow path A2 formed between the second heat insulation panels G2b, G2c and the second front panel G2a of the lower door 70 (arrow ② direction). The rising external air can pass through the frame outlet 77a formed in the upper frame portion 77 described later (refer to FIG. Fig.17 ) is discharged to the upper part.

[0221] As described above, part of the air passing through the lower door 70 may pass through the door partition space D2 formed between the upper door 50 and the lower door 70 (see Figure 1 ) is discharged to the outside. In addition, the remaining air can move upward and flow into the interior of the upper door 50 (arrow ③ direction).

[0222] The air flowing into the interior of the upper door 50 can pass through the first cooling flow path A1 (arrow ④ direction) formed between the first front panel G1a and the first insulation panels G1b and G1c constituting the upper door 50. A portion of the air passing through the first cooling flow path A1 can be discharged to the front of the main body 10 of the cooking device via the panel partition space D1 (arrow ⑤ direction). In addition, the rest of the air passing through the first cooling flow path A1 can flow into the machine room S1 (arrow ⑥ direction). The air flowing into the machine room S1 can be discharged to the rear upper side of the machine room S1 (arrow 7 direction) after passing through the machine room S1.

[0223] This air flow can cool (i) the lower door 70, (ii) the upper door 50, and (iii) the control units 21, 22, and 25 disposed in the machine room S1. The cooling structure of the doors 50 and 70 using external air will be described in detail later.

[0224] exist Figures 4 to 6 , the second box body 40 is shown. The interior of the lower storage space 41 disposed inside the second box body 40 can be photographed by the image acquisition module 100. At this time, in this embodiment, the lower storage space 41 can not only be photographed by the image sensing device 170 constituting the image acquisition module 100, but also can be improved by using the lighting device 180 constituting the image acquisition module 100. Figures 4 to 6 In FIG. 1 , a dotted line indicates a situation where light is irradiated using the lighting device 180 .

[0225] First, refer to Figure 4 An image sensing device 170 may be disposed at the center of the image acquisition module 100. With the image sensing device 170 as the center, a plurality of lighting devices 180 may be disposed on both sides. The plurality of lighting devices 180 increase the illumination of the lower storage space 41 so that the image sensing device 170 can obtain a clearer image.

[0226] The plurality of lighting devices 180 are arranged to face the lower storage space 41, and can irradiate light to the lower storage space 41. The plurality of lighting devices 180 can irradiate the lower storage space 41 at different angles. Thus, the illumination of the entire area of ​​the lower storage space 41 can be uniformly improved. Specifically, the plurality of lighting devices 180 can irradiate the upper surface, the lower surface, and the left and right sides of the lower storage space 41.

[0227] Reference Figure 4 and Figure 5 In the plurality of lighting devices 180, the first lighting units 180a arranged relatively close to the image sensing device 170 are arranged on the left and right sides with the image sensing device 170 as the center, and a pair of the first lighting units 180a can be provided. In the plurality of lighting devices 180, a second lighting unit 180b can be arranged outside the first lighting unit 180a. Similar to the first lighting unit 180a, the second lighting unit 180b can also be arranged on both sides with the image sensing device 170 as the center, and a pair of the second lighting units 180b can be provided.

[0228] On the other hand, the ranges of light irradiated by the plurality of lighting devices 180 may overlap with each other. Figure 5 As shown, the pair of first lighting units 180a irradiate light toward the center of the lower storage space 41 based on the left-right direction, so that they can overlap each other in a certain area. The area where the light irradiated by the pair of first lighting units 180a overlaps each other may include the center of the lower storage space 41. As a result, the illumination of the cooked object F arranged in the center of the lower storage space 41 can be relatively higher than that of the periphery.

[0229] In addition, the area where the second lighting unit 180b irradiates light and the area in the left-right direction where the first lighting unit 180a irradiates light may overlap each other. Figure 5, the area illuminated by the first lighting unit 180a and the area illuminated by the second lighting unit 180b overlap to a certain extent, so that a high illumination area can be formed in the center of the lower storage space 41 based on the left-right direction. Based on the left-right direction, the food F is arranged in the center of the lower storage space 41, so the lighting device 180 can illuminate the food F more brightly.

[0230] At this time, Figure 5 The first lighting unit 180a and the second lighting unit 180b may be set to emit light in different directions. Compared with the second lighting unit 180b, the first lighting unit 180a is relatively more oriented toward the center of the lower storage space 41. Specifically, compared with the second lighting unit 180b, the first lighting unit 180a is more oriented toward the center of the lower storage space 41. Figure 5 The first lighting unit 180a and the second lighting unit 180b irradiate light toward a larger area based on the left-right direction, thereby eliminating shadow areas.

[0231] On the other hand, Figure 6 The up and down direction ( Figure 1 The direction of light emitted by the second lighting unit 180b can be set to be different from the direction of light emitted by the first lighting unit 180a. Specifically, compared with the first lighting unit 180a, the second lighting unit 180b emits light in a direction biased toward the bottom of the lower storage space 41. Therefore, the first lighting unit 180a and the second lighting unit 180b are arranged in the vertical direction ( Figure 1 The light is irradiated toward a larger area (in the Z-axis direction) as a reference, thereby eliminating the shadow area.

[0232] In addition, the area where the second lighting unit 180b irradiates light and the up-down direction ( Figure 1 The regions in the Z-axis direction may also overlap with each other. Figure 6 , the area illuminated by the light of the first lighting unit 180a and the area illuminated by the light of the second lighting unit 180b overlap to a certain extent, so that the light of the first lighting unit 180a and the area illuminated by the light of the second lighting unit 180b can be illuminated in the up and down direction ( Figure 1 The Z-axis direction is used as a reference, and a region with high illumination is formed in the center of the lower storage space 41. Figure 1 The object F to be cooked is arranged at the center of the lower storage space 41, so the lighting device 180 can illuminate the object F to be cooked more brightly.

[0233] Hereinafter, the structure in which the external air flows along the interior of the upper door 50 and the lower door 70 and the structure in which the image acquisition module 100 is used to illuminate the interior of the lower storage space 41 and acquire an image will be described in detail.

Fig.11 The embodiment shows that most of the image acquisition module 100 is disposed on the upper portion of the perspective portion V. As another example, the image acquisition module 100 may also be disposed on the left and right sides or the lower portion of the perspective portion V.

[0248] The frame of the lower door 70 may be composed of a door body. The door body may include lower door frames 72, 77, 80, 90 and a lower door panel G2. When the lower door frames 72, 77, 80, 90 and the lower door panel G2 are assembled, the door body may have a substantially hexahedral structure.

[0249] The lower door frame 72, 77, 80, 90 may include a plurality of frame parts. In this embodiment, the lower door frame 72, 77, 80, 90 may include a front frame part 72, a rear frame part 80, an inner frame part 90 and an upper frame part 77. They may be combined with each other to form a lower door frame 72, 77, 80, 90. Here, "front" refers to the front of the lower door 70 (in Fig.11 The left side of the reference is the reference direction.

[0250] The front frame portion 72 may be disposed in front of the lower door frames 72, 77, 80, 90. More precisely, the front frame portion 72 may form a front skeleton of the lower door frames 72, 77, 80, 90. A pair of front side plates 72a may be provided on both sides of the front frame portion 72. A front lower plate 72b may be connected between the pair of front side plates 72a. The front side plates 72a and the front lower plate 72b may be connected to each other to form a substantially U shape.

[0251] A front opening portion 72c may be formed between the front side plate 72a and the front lower plate 72b. The front opening portion 72c may be a hollow space opened in the front-to-back direction. The front opening portion 72c may be provided with a lower door panel G2 (see Fig.18 ) of the second front panel G2a. It can also be considered that the opening portion of the front opening 72c is filled by the second front panel G2a.

[0252] More specifically, the area of ​​the lower door panel G2 is larger than the area of ​​the second front opening 72c, so a portion of the front side panel 72a and a portion of the front lower panel 72b can be stacked with the second front panel G2a. Fig.13 , it can be seen that the second front panel G2a overlaps with the front frame portion 72.

[0253] The second front panel G2a may be disposed on one side of the second front side plate 72a across the front frame portion 72. The lower handle 75 may be disposed on the opposite side of the second front side plate 72a. At this time, an additional fastener (not shown) may be fastened to the handle assembly portion 75a of the lower handle 75 after passing through the panel fastening holes G2a' of the second front side plate 72a and the second front panel G2a.

[0254] Re-reference Fig.11 , it can be seen that the image acquisition module 100 is configured on the second front panel G2a. At this time, the image acquisition module 100 can be bonded to the back side of the second front panel G2a facing the lower storage space 41. More precisely, a portion of the front surface of the image acquisition module 100 and a portion of the back surface of the second front panel G2a can be bonded to each other. Fig.11 In the figure, K1 and K2 represent the bonding areas between the front surface of the image acquisition module 100 and the back surface of the second front panel G2a.

[0255] Reference Fig.12 The rear panel G2c of the second heat-insulating panels G2b and G2c constituting the back side of the lower door 70 may be exposed toward the lower storage space 41. The rear panel G2c may also be provided with the see-through portion V. The see-through portion V of the rear panel G2c and the see-through portion V of the second front panel G2a are continuously arranged with a predetermined interval, and therefore are given the same reference numerals. Although not given a reference numeral, the inner panel G2b of the second heat-insulating panels G2b and G2c that is not exposed to the outside of the lower door 70 may also be provided with a see-through portion V.

[0256] Reference Fig.14 When the lower door panel G2 is observed, the lower door panel G2 may include three panels in total. The three panels are composed of a second front panel G2a disposed at the front, an inner panel G2b disposed inside the lower door 70, and a rear panel G2c disposed at the rear. The second front panel G2a faces forward (the front side of the home appliance body 10), Figure 1 The rear panel G2c is exposed in the opposite direction, i.e., the rear direction (towards the rear side of the lower storage space 41).

[0257] The inner panel G2b and the rear panel G2c can constitute the second heat-insulating panels G2b and G2c. The inner panel G2b and the rear panel G2c can be stacked on each other at a predetermined interval. In addition, the hollow space between the inner panel G2b and the rear panel G2c can be in a vacuum state, thereby improving the heat-insulating effect. As another example, the inner panel G2b can be omitted from the second heat-insulating panels G2b and G2c, and only the rear panel G2c is included. Reference numeral 76 indicates a second panel spacer 76 that is disposed between the inner panel G2b and the rear panel G2c and maintains the interval between them.

[0258] A setting area T1-T4 may be provided between the second front panel G2a and the second insulation panels G2b and G2c. The setting area T1-T4 is provided in the hollow space between the second front panel G2a and the second insulation panels G2b and G2c. The setting area T1-T4 may be a portion where the image acquisition module 100 and the connector module 200 are configured.

[0259] The second cooling flow path A2 may also be provided between the second front panel G2a and the second heat insulation panels G2b and G2c. The second cooling flow path A2 may be the entire space between the second front panel G2a and the second heat insulation panels G2b and G2c. The setting area T1-T4 may be arranged outside the perspective portion V with the perspective portion V as the center. Therefore, the second cooling flow path A2 is larger than the setting area T1-T4, so that it can also be regarded that the setting area T1-T4 constitutes a part of the second cooling flow path A2.

[0260] The air may flow into the lower door panel G2 through the second cooling flow path A2. Therefore, the second cooling flow path A2 may also be referred to as a flow space A2 for air flow.

[0261] exist Fig.13 The setting area T1-T4 is shown in FIG. The setting area T1-T4 is a portion where the image acquisition module 100 and the connector module 200 are configured. Fig.13 The dotted lines are shown to help understand the setting areas T1-T4. Fig.13 In the figure, the setting areas T1-T4 are indicated on the surface of the second front panel G2a, but in fact, the setting areas T1-T4 can be set between a plurality of panels, more precisely, can be set between the second front panel G2a and the second insulation panels G2b, G2c.

[0262] At this time, the upper frame portion 77 of the lower door frames 72, 77, 80, 90 blocks a portion of the upper end of the back surface of the second front panel G2a, but a portion of the setting area T1-T4 can be formed in a portion that is not blocked by the upper frame portion 77. More precisely, the first setting area T1, T3 of the setting area T1-T4 can be set at the lower portion of the upper frame portion 77 that is not blocked by the upper frame portion 77.

[0263] The setting areas T1-T4 may include (i) first setting areas T1 and T3 formed along the edge of the perspective portion V in a first direction; (ii) second setting areas T2 and T4 formed along the edge of the perspective portion V in a second direction different from the first direction. In this embodiment, the first direction is the left-right direction (the left-right width direction of the lower door 70, Figure 1 The second direction is the vertical direction (the height direction of the lower door 70, Figure 1 in the Z-axis direction).

[0264] The first setting areas T1 and T3 can be respectively formed at the upper part T1 and the lower part T3 of the perspective part V based on the perspective part V. The second setting areas T2 and T4 can be respectively formed at the two sides of the perspective part V based on the perspective part V. If divided in different ways, the setting areas T1-T4 can also be divided into: (i) an upper area T1 set at the upper part of the perspective part V; (ii) a right side area T2 set at the right side of the perspective part V; (iii) a lower area T3 set at the lower part of the perspective part V; (iv) a left side area T4 set at the left side of the perspective part V. This division is based on Fig.16 Based on the benchmark.

[0265] The first setting areas T1, T3 and the second setting areas T2, T4 may be connected to each other. Both ends of the first setting areas T1, T3 and both ends of the second setting areas T2, T4 are connected to each other. Thus, the setting areas T1-T4 may be formed as spaces continuous with each other. Thus, the image acquisition module 100 and the connector module 200 may also be configured to pass through a plurality of setting areas T1-T4. In the present embodiment, a portion of the image acquisition module 100 is configured in the first setting areas T1, T3. The remaining portion of the image acquisition module 100 is configured in the second setting areas T2, T4 connected to the first setting areas T1, T3. In the present embodiment, the connector module 200 is configured in the second setting areas T2, T4.

[0266] At least a portion of the installation area T1-T4 may be installed in an area where a portion of the lower door frame 72, 77, 80, 90 blocks the back surface of the second front panel G2a. Fig.15 , showing a situation where the rear frame portion 80 blocks a portion of the image acquisition module 100. Here, the rear frame portion 80 blocks a portion of the image acquisition module 100 based on the direction of the back of the lower door 70, that is, the direction of the back of the lower door 70 viewed from the inside of the lower storage space 41 when the lower door 70 is closed.

[0267] The image sensing device 170 and the lighting device 180 constituting the image acquisition module 100 are exposed through the rear through-hole portion 81 of the rear frame portion 80, but a portion of the image acquisition module 100 corresponding to the upper portion of the image sensing device 170 and the lighting device 180 may be blocked by the rear frame portion 80. For reference, Fig.15 The figure shows a state in which the lighting device 180 is blocked by the cover plate 190 and only the cover plate 190 is visible.

[0268] Thus, even if the user opens the lower door 70, the remaining parts except for the image sensing device 170 and the lighting device 180 may not be exposed through the transparent portion V. In particular, when the lower door 70 is opened and closed in a pull-down manner, the image sensing device 170 and the lighting device 180 may be shielded by the rear frame portion 80 within the opening and closing angle.

[0269] As described later, the image acquisition module 100 is disposed in the first setting area T1, T3, and the connecting wire W2 for signal transmission and power supply between the image acquisition module 100 and the main control unit can be disposed in the second setting area T2, T4.

[0270] The second front panel G2a may also be divided into the perspective portion V and an edge portion of the edge configuration surrounding the perspective portion V. In this case, the setting areas T1-T4 may be set on the back of the edge portion. Here, the edge portion may be processed to be opaque. Thus, the setting areas T1-T4 set on the back of the edge portion will not be exposed in front of the lower door 70, that is, in front of the cooking device. The edge portion may be made by etching a part of the second front panel G2a to increase the surface roughness, or may be made by coating an additional film, or may be processed to be opaque by a spraying process.

[0271] On the other hand, an upper frame portion 77 may be disposed above the second front opening portion 72c. The upper frame portion 77 may shield a portion of the second front panel G2a. An image acquisition module 100 described later may be fixed to the upper frame portion 77.

[0272] A frame outlet 77a may be formed in the upper frame portion 77. The frame outlet 77a may be an outlet for discharging air to the outside through the second cooling flow path A2 formed inside the lower door 70. The frame outlet 77a faces the bottom surface of the upper door 50, so the air discharged from the frame outlet 77a can be naturally transferred to the first cooling flow path A1 through the lower part of the upper door 50. That is, the frame outlet 77a is provided on the opposite side of the inlet I of the second cooling flow path A2, so that it can be called the outlet of the second cooling flow path A2. In addition, as described later, the frame outlet 77a may also be connected to the setting area T1-T4.

[0273] Reference Fig.14 , the lower door 70 may include a lower door hinge 78 . Fig.17 The lower door hinge 78 is shown to be installed inside the lower door 70. A hinge hook arm 78a may protrude from the lower door hinge 78. The hinge hook arm 78a may be locked and fixed to the main body 10 of the cooking device after passing through the inner hinge passing portion 98 of the inner frame portion 90 and the rear hinge passing portion 88 of the rear frame portion 80, respectively. Reference numeral 79 is a hinge spring 79, which may be sleeved on the spring guide 78b of the lower door hinge 78.

[0274] The front frame portion 72 may be disposed on one side across the lower door panel G2. The inner frame portion 90 and the rear frame portion 80 may be disposed on the opposite side. The inner frame portion 90 and the rear frame portion 80 are separated from each other, and between them, (i) a heat insulating space may be formed; and (ii) the second heat insulating panels G2b and G2c may be fixed. The inner frame portion 90 is disposed between the rear frame portion 80 and the front frame portion 72 so as not to be exposed to the outside.

[0275] The rear frame portion 80 may be formed in a substantially square frame shape. When the lower door 70 is closed, the rear frame portion 80 may face the front of the lower storage space 41. A rear through portion 81 may be formed in the center of the rear frame portion 80. The rear through portion 81 may have a structure that opens to the front and rear sides so that the perspective portion V can see through the interior of the lower storage space 41.

[0276] A rear side plate 82 may be provided on the side of the rear frame portion 80. The rear side plate 82 may overlap the front side plate 72a. A rear reinforcing rib portion 87 surrounding the periphery of the rear through portion 81 may be provided on the rear frame portion 80. Reference numeral 88 denotes a rear hinge passing portion 88 through which the hinge hook arm 78a of the lower door hinge 78 passes.

[0277] The rear frame portion 80 may shield a portion of the image acquisition module 100. More precisely, the image sensing device 170 and the lighting device 180 constituting the image acquisition module 100 are exposed toward the rear, i.e., the direction of the lower storage space 41 (based on the closed state) through the rear through portion 81, but a portion of the image acquisition module 100 corresponding to the upper portion of the image sensing device 170 and the lighting device 180 may be shielded by the rear frame portion 80. Thus, even if the user opens the lower door 70, the remaining portion except for the image sensing device 170 and the lighting device 180 may not be exposed through the perspective portion V.

[0278] The rear frame portion 80 may be combined with the inner frame portion 90. The rear frame portion 80 and the inner frame portion 90 may be combined with an additional frame fastener B2 (see Fig.18 When the rear frame portion 80 is combined with the inner frame portion 90, the second heat insulation panels G2b, G2c and the second panel spacer 76 disposed therebetween may also be fixed together.

[0279] When the lower door 70 is closed, the inner frame portion 90 may be spaced apart from the rear frame portion 80 and arranged in the up-down direction ( Figure 1 The inner frame portion 90 may be provided with an inner through portion 91 formed in the center thereof.

[0280] An inner plate 92 may be provided on a side surface of the inner frame portion 90. The inner plate 92 may overlap the front plate 72a and the rear plate 82, respectively.

[0281] The inner frame portion 90 may be provided with an inner rib portion 97 surrounding the periphery of the inner through portion 91. Reference numeral 98 denotes an inner hinge passing portion 98 through which the hinge hook arm 78a of the lower door hinge 78 passes.

[0282] Reference Fig.15 and Fig.16 The inner frame portion 90 may be provided with an anti-deformation portion 99. The anti-deformation portion 99 may be a reinforcing rib structure protruding from the inner frame portion 90 toward the back side of the front frame portion 72. More precisely, the anti-deformation portion 99 may protrude in a direction facing the supporting protrusion 149 provided on the image acquisition module 100.

[0283] The anti-deformation portion 99 may protrude to a position separated by a predetermined distance from the supporting protrusion 149. When the tip of the anti-deformation portion 99 is separated from the surface of the supporting protrusion 149, the vibration generated during the operation of the second door 70 can be blocked from being transmitted toward the image acquisition module 100, thereby improving the durability of the image sensing device 100.

[0284] Even if the anti-deformation portion 99 is separated from the supporting protrusion 149 by a predetermined distance as described above, when the module cover 110, 140 constituting the image acquisition module 100 is deformed due to conditions such as high temperature, the anti-deformation portion 99 can contact the supporting protrusion 149, thereby preventing the module cover 110, 140 from being excessively deformed. In this embodiment, the anti-deformation portion 99 is arranged in the setting area T1-T4.

[0285] On the other hand, in the present embodiment, the support protrusion 149 and the anti-deformation portion 99 may also protrude toward each other from the mutually facing surfaces of the image acquisition module 100 and the inner frame portion 90. Thus, compared with the case where the member for preventing deformation (anti-deformation portion / support protrusion) is formed only on one side of the image acquisition module 100 and the door frame 90, the protruding length of the member for preventing deformation can be reduced.

[0286] The anti-deformation parts 99 may be respectively provided at both ends of the inner frame part 90. Thus, when the image acquisition module 100 is deformed due to heat, both ends of the image acquisition module 100, which are the most bent parts, may be supported by the anti-deformation parts 99. Therefore, the deformation of the image acquisition module 100 can be more effectively prevented.

[0287] At this time, the image sensing device 170 and the lighting device 180 provided in the image acquisition module 100 may be arranged between the plurality of the anti-deformation parts 99. Thus, the anti-deformation parts 99 can support both ends of the image acquisition module 100 via the image sensing device 170 and the lighting device 180 as the heating element, so that even if the image acquisition module 100 is deformed, the image acquisition module 100 can be supported more effectively.

[0288] The anti-deformation portion 99 may protrude in the front-to-back direction of the plurality of panels stacked on each other. In other words, it can also be considered that the anti-deformation portion 99 protrudes in the direction that narrows the second cooling flow path A2. The second cooling flow path A2, as a hollow space, can provide a space for the image acquisition module 100 to deform. Therefore, when the anti-deformation portion 99 protrudes in the direction that narrows the second cooling flow path A2, the deformation of the image acquisition module 100 can be more effectively prevented.

[0289] As another example, the second door 70 may be provided with only one of the anti-deformation portion 99 and the supporting protrusion 149. Fig.61 (b), the image acquisition module 100 may be provided with a support protrusion 149, and the anti-deformation portion 99 may be omitted in the inner frame portion 90. In this case, the length of the support protrusion 149 may be greater than that of the aforementioned embodiment (refer to Fig.61 (a)) of the support protrusion 149. In addition, refer to Fig.61 (c), the support protrusion 149 can be omitted in the image acquisition module 100, and the anti-deformation portion 99 can be provided in the inner frame portion 90. In this case, the length of the anti-deformation portion 99 can be greater than that of the aforementioned embodiment (refer to Fig.61 As another example, the inner frame portion 90 may be provided with a support protrusion 149, and the image acquisition module 100 may be provided with an anti-deformation portion 99.

[0290] A plurality of anti-deformation portions 99 may also be provided on the inner frame portion 90. In the present embodiment, the anti-deformation portions 99 may be provided on the left and right sides of the inner through-hole portion 91, respectively. More precisely, the anti-deformation portions 99 may be provided at portions corresponding to the corners of the inner through-hole portion 91, and may be provided at portions where the inner reinforcing rib portion 97 is cut away. Two anti-deformation portions 99 may respectively support the supporting protrusions 149 provided at the end portions on both sides of the image acquisition module 100. The structures of the anti-deformation portions 99 and the supporting protrusions 149 will be described again later.

[0291] Reference Fig.17 , which shows a cross-sectional view of the lower door 70. It can be observed that the lower door panel G2 is fixed between the front frame portion 72, the rear frame portion 80, and the inner frame portion 90. The second front panel G2a can be closely attached to the surface of the front frame portion 72. The image acquisition module 100 can be arranged on the surface of the second front panel G2a. The image acquisition module 100 can be arranged in the first setting area T1, T3 formed at the upper end of the second front panel G2a and the lower end of the upper frame portion 77.

[0292] A second cooling flow path A2 may be formed between the second front panel G2a and the inner panel G2b of the second insulation panels G2b and G2c. The second cooling flow path A2 may be the entire space between the second front panel G2a and the inner panel G2b. Fig.17 The arrows indicate the flow direction of the external air passing through the second cooling flow path A2. The frame outlet 77a of the upper frame portion 77 is disposed at the upper end of the second cooling flow path A2 to form an air outlet.

[0293] As described above, the setting area T1-T4 can be arranged outside the perspective portion V with the perspective portion V as the center. Therefore, the second cooling flow path A2 is larger than the setting area T1-T4, so it can also be considered that the setting area T1-T4 constitutes a part of the second cooling flow path A2. The lower door hinge 78 can also be arranged in the second cooling flow path A2.

[0294] The space between the rear panel G2c and the inner panel G2b separated from each other can also maintain a vacuum state. Fig.18 The heat transferred from the rear panel G2c to the inner panel G2b can also be greatly reduced. The heat transferred to the second cooling flow path A2 can be discharged by means of the external air flowing in the second cooling flow path A2. Reference numerals S3 and S4 are heat-insulating spaces formed between the rear frame portion 80 and the inner frame portion 90, which can be filled with heat-insulating materials.

[0295] Reference Figures 19 to 21 , the cooling structure of the lower door 70 is further described in detail. For reference, Figures 19 to 21 FIG. 2 shows a situation viewed from the lower side of the lower door 70. Fig.19 , showing a case where the image acquisition module 100 is omitted in the lower door 70. External air can flow in through the inlet portion I opened toward the lower side of the lower door 70, and then be discharged to the frame outlet 77a of the upper frame portion 77 through the second cooling flow path A2. Fig.19 The frame outlet 77a located on the opposite side to the lower end of the lower door 70 is shown in a state where it is open.

[0296] As described above, if the image acquisition module 100 is omitted from the lower door 70, the second cooling flow path A2 as the air flow space can have a sufficiently large cross-sectional area because the rest of the lower door except the lower door hinges 78 arranged on both sides can serve as the second cooling flow path A2.

[0297] Fig. 20 The figure shows a case where the image acquisition module 100 is disposed in the lower door 70. Due to the presence of the image acquisition module 100, the cross-sectional area of ​​the second cooling flow path A2 is reduced. Therefore, the flow of the external air flowing in the second cooling flow path A2 may be relatively unsmooth. In this embodiment, by providing the module flow path portion R in the image acquisition module 100, the cross-sectional area of ​​the second cooling flow path A2 can be increased, and the air can flow smoothly.

[0298] In more detail, the image acquisition module 100 may be disposed on the second cooling flow path A2. Thus, the image acquisition module 100 may interfere with the external air passing through the second cooling flow path A2. Fig. 20 As shown, the module housings 110 and 140 constituting the image acquisition module 100 may reduce the cross-sectional area of ​​the second cooling flow path A2. In this embodiment, based on the accompanying drawings, the image acquisition module 100 may be arranged along the left and right directions of the second cooling flow path A2 ( Figure 1 The image acquisition module 100 may be formed continuously from the left end portion to the right end portion of the second cooling flow path A2.

[0299] The module flow path portion R may be provided in the image acquisition module 100. The module flow path portion R may be formed in a form in which a portion of the image acquisition module 100 is recessed toward the second front panel G2a. In this way, the module flow path portion R formed by the recessed portion of the image acquisition module 100 may constitute a portion of the second cooling flow path A2. The module flow path portion R may increase the cross-sectional area of ​​the second cooling flow path A2.

[0300] The module flow path R may be disposed between the image sensing device 170 and the lighting device 180 constituting the image acquisition module 100. In order to realize the image acquisition and lighting functions, the image sensing device 170 and the lighting device 180 need to be oriented toward the lower storage space 41, i.e. Fig. 20 The module flow path portion R may have a structure that is more recessed forward than the image sensing device 170 and the lighting device 180 .

[0301] It can be considered that a part of the space of the setting area T1 is occupied by the image acquisition module 100, and air circulation channels BN and EP connected to the second cooling flow path A2 as the flow space are formed in the remaining hollow space of the setting area T1.

[0302] Reference will Fig. 20 Enlarged Fig.21 The air circulation passages BN and EP may include a plurality of panels G2a and G2b arranged in the front-rear direction ( Figure 1 The flow path connecting portion BN has a first width l1 in the X-axis direction of the cooling channel A2. The flow path connecting portion BN connects the second cooling channel A2 in the vertical direction thereof, but is a portion with a relatively small width. In this case, the plurality of panels G2a and G2b may also be referred to as the first panel G2a and the second panel G2b.

[0303] More precisely, the first width l1 represents the straight-line distance between the surface of the flow path connection portion BN and the surface of the second inner panel G2b. That is, since the first width l1 is a portion whose width is reduced due to the presence of the image acquisition module 100, the flow path connection portion BN can also be regarded as a bottleneck area BN.

[0304] In addition, the air circulation passages BN and EP may also be provided with a plurality of second panels G2a and G2b arranged in the front-rear direction (in Fig.21 As the reference up and down direction, Figure 1 The flow path expansion portion EP has a second width l2 in the X-axis direction of the module flow path portion R. The flow path expansion portion EP may be formed in a recessed portion of the module flow path portion R. The second width l2 represents a straight-line distance between the surface of the module flow path portion R and the surface of the second inner panel G2b facing each other. The second width l2 may be greater than the first width l1.

[0305] The total width of the air circulation passages BN and EP may be the sum l1+l2 of the first width l1 and the second width l2 at the portion where the module flow path section R is arranged. In the portion where the air circulation passages BN and EP are widened as described above, air can flow smoothly.

[0306] If the flow path expansion portion EP is not present, the air circulation passages BN and EP may be formed only by the flow path connection portion BN. That is, since the air circulation passages BN and EP have relatively narrow cross-sectional areas, the air cannot circulate smoothly. Fig.21 It can be observed that in the portion where the module flow path portion R is provided, the width direction of the second cooling flow path A2 (the vertical direction based on the drawing, Figure 1 The width increase part (in the X-axis direction) Fig.21 Therefore, even if the air flowing in from the outside rises and meets the image acquisition module 100, it can be smoothly discharged to the frame outlet 77a while passing through the module flow path portion R.

[0307] On the other hand, the flow path expansion portion EP may be provided even if the module flow path portion R is omitted. For example, the flow path expansion portion EP may be formed in the hollow space of the installation area T1 at a portion where the surfaces of the plurality of panels G2a and G2b directly face each other. Fig.73, the image acquisition module 100 may be composed of a shooting unit 100A1 and an illumination unit 100A2 that are separated from each other. The flow path expansion portion EP may be provided between the shooting unit 100A1 and the illumination unit 100A2. In this case, the width of the flow path expansion portion EP may be further increased by an amount corresponding to the thickness of the omitted module flow path portion R.

[0308] The inlet and outlet of the flow path expansion portion EP may be opened along the flow direction of the air. Fig.24 , it can be observed that the flow path expansion portion EP is continuously opened from the lower part to the upper part. Thus, the second cooling flow path A2 can be continuously connected through the inlet and the outlet of the flow path expansion portion EP.

[0309] Re-reference Fig.21 The flow path connection portion BN and the flow path expansion portion EP can be opened toward the surface of the second inner panel G2b, respectively. That is, a continuous hollow space is formed between the surface of the image acquisition module 100 and the surface of the second inner panel G2b, and between the surface of the module flow path portion R and the surface of the second inner panel G2b, thereby increasing the air flow area.

[0310] At this time, the image acquisition module 100 may have a thickness that does not block the frame outlet 77a based on the flow direction of the second cooling flow path A2. Fig.21 It can be confirmed that the image acquisition module 100 protrudes toward the inner frame portion 90, but does not block the frame outlet 77a. Fig.21 The most protruding portion of the image acquisition module 100 (with the image acquisition module 100 as the reference) may also be separated from the second inner panel G2b. The frame outlet 77a may be formed between the image acquisition module 100 and the second inner panel G2b.

[0311] Fig. 22 The lower door 70 is shown in a state where the inner frame portion 90 and the rear frame portion 80 are omitted. The image acquisition module 100 can be arranged in the first setting area T1, T3 corresponding to the upper part of the perspective portion V. The thickness (length in the front-to-back direction) of the image acquisition module 100 is smaller than the thickness (length in the front-to-back direction) of the upper frame portion 77. The image acquisition module 100 can be in close contact with the second front panel G2a. As a result, the back side of the upper frame portion 77 can protrude further toward the lower storage space 41 (the right side direction based on the figure) than the back side of the image acquisition module 100. The frame discharge port 77a can be provided in the portion of the upper frame portion 77 that protrudes more than the image acquisition module 100.

[0312] The following describes a structure in which the second cooling flow path A2 is widened by the module flow path portion R of the lower door 70 to avoid a bottleneck phenomenon in the air flow. Figure 23 to Figure 25 A cross-sectional view of the lower door 70 is shown. Figure 23 to Figure 25 Shows Fig. 22 The cross-sections of different parts of Fig.23 It can be observed that the second cooling channel A2 is narrowed at the portion where the image acquisition module 100 is configured. Fig.23 In the embodiment, the second lighting unit 180b of the lighting device 180 of the image acquisition module 100 is disposed on the upper portion of the lower door 70. The protruding portion of the second lighting unit 180b narrows the second cooling flow path A2, which may form a bottleneck area BN for air flow.

[0313] In contrast, referring to the cross-sectional view based on the module flow path section R, Fig.24 , it can be seen that the second cooling flow path A2 is widened in the portion where the module flow path portion R is provided. Even if the image acquisition module 100 is present, the second cooling flow path A2 is widened by the module flow path portion R, so that smooth air flow can be achieved. Therefore, the bottleneck area BN of the air flow generated in other parts of the image acquisition module 100 may not be formed in the portion where the module flow path portion R is provided.

[0314] Fig.25 A cross-sectional view based on the image sensing device 170 is shown. Fig.25 The internal structure of the lower door 70 shown in FIG. Fig.23 Similarly, the second cooling channel A2 is narrowed at a portion where the image sensing device 170 is disposed, forming a bottleneck area BN for air flow.

[0315] like Fig.23 and Fig.25 As shown, the contact area between the portion where the image sensing device 170 and the lighting device 180 are provided and the air flowing in the second cooling flow path A2 can be increased. Thus, the image sensing device 170 and the lighting device 180 can be cooled more effectively with the aid of external air. The image sensing device 170 and the lighting device 180, which generate relatively large amounts of heat, are arranged in a direction that narrows the second cooling flow path A2, thereby increasing the contact area with the external air and enabling them to be effectively cooled. On the contrary, the module flow path portion R is provided between the image sensing device 170 and the lighting device 180, which generate little heat, so that the air flows smoothly, thereby enabling good flow of external air.

[0316] Re-reference Fig. 22, the connector module 200 described later can be arranged in the second setting area T2, T4. The connector module 200 is arranged in a setting area different from the image acquisition module 100. Of course, although the main unit 100A as a part of the image acquisition module 100 is arranged in the first setting area T1, T3, a part of the connection unit 100B as the rest of the image acquisition module 100 can be arranged in the second setting area T2, T4. In this embodiment, the image acquisition module 100 and the connector module 200 can be electrically connected to each other using a connecting wire W2.

[0317] The structure of the image acquisition module 100 is described in detail below. Fig.26 The figure shows a situation in which the front frame part 72, the second front panel G2a and the image acquisition module 100 of the components constituting the lower door 70 of one embodiment of the present invention are combined with each other. As shown in the figure, a part of the image acquisition module 100 can be arranged along the first direction (the left-right direction of the figure reference). The rest of the image acquisition module 100 can be arranged along the second direction (the up-down direction of the figure reference). As another example, the image acquisition module 100 can also be arranged only along the first direction or only along the second direction in the setting area T1-T4.

[0318] In this embodiment, the image acquisition module 100 may include a main unit 100A arranged along a first direction and a connection unit 100B arranged along a second direction different from the first direction. The main unit 100A may be arranged at the upper end of the outer side of the perspective portion V. The connection unit 100B may be connected to one end of the main unit 100A and may be arranged at the outer side end of the perspective portion V. As described above, the image acquisition module 100 is arranged at the outer side of the perspective portion V along the edge of the perspective portion V, so that the perspective portion V may not be blocked. In addition, the installation of the image acquisition module 100 may utilize the setting areas T1-T4 as spaces that do not need to be viewed through the perspective portion V, so the doors 50 and 70 do not need to be redesigned, or only minimal design changes are required.

[0319] The main unit 100A may be provided with the image sensing device 170 and the lighting device 180. In order to obtain an image of the interior of the lower storage space 41, the image sensing device 170 may be provided at the center of the main unit 100A. In this embodiment, one image sensing device 170 is provided at the center of the main unit 100A. As another example, a plurality of image sensing devices 170 may also be provided at the main unit 100A.

[0320] The lighting device 180 may be disposed at a position separated from the image sensing device 170. The lighting device 180 may be disposed separated from the image sensing device 170 across the module flow path portion R. In this embodiment, the lighting device 180 is disposed on both sides of the image sensing device 170 with the image sensing device 170 as the center. The lighting devices 180 disposed on both sides of the image sensing device 170 illuminate the interior of the lower storage space 41, so that the image sensing device 170 obtains a clearer image and enables the user to more easily observe the interior of the lower storage space 41.

[0321] The lighting device 180 disposed on both sides of the main unit 100A may be composed of a plurality of lighting units 180a and 180b. The first lighting unit 180a disposed relatively close to the image sensing device 170 among the plurality of lighting units 180a and 180b may be disposed on the left and right sides with the image sensing device 170 as the center to form a pair. Among the plurality of lighting units 180a and 180b, a second lighting unit 180b may be disposed outside the first lighting unit 180a. Similar to the first lighting unit 180a, the second lighting unit 180b may be disposed on both sides with the image sensing device 170 as the center, and a pair of second lighting units 180b may be provided.

[0322] As described above, the ranges of light irradiated by the plurality of lighting units 180a and 180b may overlap each other. In this embodiment, the first lighting unit 180a is arranged to be tilted toward the image sensing device 170. In addition, the second lighting unit 180b is arranged to be tilted toward the lower side, that is, toward the lower end of the lower door 70. By setting the lighting device 180 at such an inclined angle, the lighting device 180 can evenly illuminate a larger space.

[0323] Reference Fig. 27 , wires for power supply or signal transmission may be arranged inside the main body 10 and the lower door 70 of the household appliance. Such wires may include: a main wire W1 for connecting the connector module 200 of the lower door 70 and the control parts 21, 22, 25 inside the main body 10; and a connecting wire W2 for connecting the connector module 200 and the image acquisition module 100. If necessary, the operator may also separate the main wire W1 from the connector module 200 and maintain or repair the image acquisition module 100. For reference, Fig. 27 The image acquisition module 100 is shown in a see-through state, and the image acquisition module 100 may be shielded by an edge portion of the second front panel G2a.

[0324] Fig.28The image acquisition module 100 is shown as being separated from the lower door 70. The image acquisition module 100 may be disposed on the second front panel G2a. The image acquisition module 100 may be installed on the second front panel G2a after the image sensing device 170 and the lighting device 180 are first assembled to the module housings 110 and 140 constituting the image acquisition module 100. Fig.28 In the figure, the inner frame portion 90 and the rear frame portion 80 which are connected to the front frame portion 72 via the image acquisition module 100 are omitted.

[0325] Reference Fig.28 The module cover 110, 140 forming the skeleton of the image acquisition module 100 may be composed of a plurality of parts. In the present embodiment, the module cover 110, 140 includes a first cover 110 and a second cover 140. The first cover 110 and the second cover 140 may be assembled with each other to protect the image sensing device 170 and the lighting device 180 disposed therebetween. The first cover 110 may be in close contact with the second front panel G2a. The second cover 140 may face the inner panel G2b of the second heat insulation panels G2b, G2c.

[0326] The image sensing device 170 and the lighting device 180 may be installed in the installation space formed between the first cover body 110 and the second cover body 140. In this embodiment, the lighting device 180 may be provided with a cover plate 190 for protecting the light source 183 of the lighting device 180. The cover plate 190 is arranged in front of the light emitting device 183, but Fig.28 , the cover plate 190 is shown separated toward the front of the second cover body 140 to illustrate the cover plate 190. When assembling the cover plate 190, the cover plate 190 can be assembled toward the rear of the second cover body 140, that is, between the first cover body 110 and the second cover body 140 toward the inside of the second cover body 140. The assembly structure of the cover plate 190 will be described again later. Fig.28 Although not shown, the image sensing device 170 may also be provided with a sensor protection cover 178 for protecting the photographing sensor.

[0327] Reference Figures 28 to 30, the first cover body 110 is described. The first cover body 110 can be assembled with the second cover body 140 to form a module cover body 110, 140. The first cover body 110 can be arranged along a plurality of directions different from each other. In this embodiment, the portion of the first cover body 110 formed along the first direction and the portion formed along the second direction are connected to each other. Here, the portion formed along the first direction is the mounting plate 111, and the portion formed along the second direction is the first connecting body 130. As another example, the first cover body 110 can also be formed only along the first direction or the second direction.

[0328] Similar to the first cover body 110, the second cover body 140 can be arranged in a plurality of directions different from each other. In this embodiment, the portion formed along the first direction and the portion formed along the second direction of the second cover body 140 are connected to each other. Here, the portion formed along the first direction is the cover body 141, and the portion formed along the second direction is the second connection body 160. As another example, the second cover body 140 can also be formed only in the first direction or the second direction.

[0329] First, when observing the first cover body 110, the first cover body 110 may have a generally thin plate-like structure. One side of the first cover body 110 may face the second front panel G2a, and the other side may face the second cover body 140. At this time, the image sensing device 170 and the lighting device 180 may be installed on the other side of the first cover body 110. As described above, a portion of the surface of one side of the first cover body 110 and a portion of the surface of the back side of the second front panel G2a may be bonded to each other. Fig.11 In FIG. 1 , K1 and K2 represent areas where bonding is performed.

[0330] Reference Fig.30 , the first cover 110 may be provided with wire guides 114a and 114b. The wire guides 114a and 114b may guide the direction in which the connecting wire W2 is fixed. The wire guides 114a and 114b may protrude from the surface of the first cover 110. The connecting wire W2 may pass around the protruding wire guides 114a and 114b. The wire guides 114a and 114b may guide the fixing direction of the connecting wire W2 together with the wire holder 115 described later.

[0331] In this embodiment, the wire guides 114a and 114b may be arranged at the portion where the mounting plate 111 and the first connection body 130 are connected to each other. The mounting plate 111 and the first connection body 130 are arranged in different directions, so the direction of the connection wire W2 can be switched between them. Therefore, the wire guides 114a and 114b can guide the direction of the connection wire W2 to switch at the portion where the mounting plate 111 and the first connection body 130 are connected to each other.

[0332] The wire guide portions 114a, 114b may include a plurality of wire guide portions 114a, 114b. Fig.30 and Fig.32 The wire guides 114a and 114b may include a first wire guide 114a disposed on the relatively outer side and a second wire guide 114b disposed on the inner side. The connecting wire W2 may pass between the first wire guide 114a and the second wire guide 114b. The first wire guide 114a can prevent the connecting wire W2 from being exposed to the outside of the image acquisition module 100. The second wire guide 114b is disposed at a position adjacent to the second lighting unit 180b, so as to prevent the connecting wire W2 from interfering with the second lighting unit 180b.

[0333] A plurality of wire holders 115 may be provided on the first cover 110. The wire holders 115 may guide the setting direction of the connecting wire W2. In the present embodiment, the plurality of wire holders 115 may be arranged along the length direction of the image acquisition module 100, that is, the length direction of the first cover 110. The connecting wire W2 may be fixed along the plurality of wire holders 115. As another example, the wire holder 115 may also be arranged on the second cover 140 instead of the first cover 110. As yet another example, the wire holder 115 may also be omitted from the image acquisition module 100.

[0334] Reference Fig.29 and Fig.30 , a plurality of the wire holders 115 can be arranged in the left-right direction. Thus, the connecting wire W2 can also be fixed in the left-right direction. The wire holder 115 can have a substantially clamp structure. That is, a pair of protruding parts (holder arms) can constitute a wire holder 115, and the connecting wire W2 can be arranged between the pair of protruding parts.

[0335] Fig.31 and Fig.32The state where the connecting wire W2 is locked and fixed to the plurality of wire holders 115 is shown. The wire holder 115 can be provided not only on the mounting plate 111 but also on the first connection body 130. In order to distinguish from the wire holder 115 provided on the mounting plate 111, the wire holder 115 of the mounting plate 111 is referred to as the first wire holder 115, and the wire holder 135 of the first connection body 130 is referred to as the second wire holder 135.

[0336] The first wire holder 115 and the second wire holder 135 can guide the connection wire W2 in different directions. In this embodiment, the first wire holder 115 can guide the installation direction of the connection wire W2 in the left-right direction, and the second wire holder 135 can guide the installation direction of the connection wire W2 in the up-down direction.

[0337] Reference Fig.33 The first wire holder 115 may include a pair of holder arms. The pair of holder arms may have structures that are symmetrical to each other. The pair of holder arms have a cantilever structure and are elastically deformable. The connecting wire W2 may be inserted between the pair of holder arms while elastically deforming the pair of holder arms toward the direction of opening each other.

[0338] At this time, a retainer inclined surface 115a is provided on the top surface of the pair of retainer arms, so that the connection wire W2 can easily elastically deform the pair of retainer arms. Reference numeral 115b indicates a retaining groove 115b for retaining the connection wire W2 so that the connection wire W2 will not be separated in a direction of separation again. The retaining groove 115b has a structure that is recessed upward, which can prevent the connection wire W2 from being separated.

[0339] Reference Fig.29 and Fig.30 The first cover body 110 may be provided with a fixing clip portion 116. The fixing clip portion 116 can fix the image acquisition module 100 to the second front frame portion 72 and the upper frame portion 77. More precisely, the fixing clip portion 116 can pre-fix the image acquisition module 100 to the upper frame portion 77 before the image acquisition module 100 is fixed to the upper frame portion 77 using additional fasteners such as bolts (not shown).

[0340] The fixing clip portion 116 may be provided on the mounting plate 111 in the first housing 110. In the present embodiment, a plurality of the fixing clip portions 116 are arranged along the upper end portion of the mounting plate 111. The upper end portion of the mounting plate 111 may face the back surface of the upper frame portion 77, and the fixing clip portion 116 may be provided on the upper end portion of the mounting plate 111 facing the upper frame portion 77 in this manner.

[0341] Fig.35 and Fig.36 The structure of the fixed clip portion 116 is shown in detail. As shown in the figure, the clip body 116a constituting the fixed clip portion 116 may have a substantially U-shape. One end of the clip body 116a may be a fixed end connected to the mounting plate 111, and the other end may be a free end connected to the fixed end. Thus, the clip body 116a has a cantilever structure that can be elastically deformed. A clip rib (not marked with a figure mark) for strengthening strength may be protruded on the surface of the clip body 116a.

[0342] The fixing clip portion 116 may be recessed to form a clip groove 116b. Fig.36 As shown, the clip groove 116b may have a structure that is open toward the back side of the second front panel G2a and recessed toward the opposite side. The fixing rib 77c protruding from the surface of the upper frame portion 77 may be inserted into the clip groove 116b. When the fixing rib 77c is inserted into the clip groove 116b, the fixing rib 77c may be locked in the clip groove 116b. Thus, the mounting plate 111 and the entire image acquisition module 100 may be pre-fixed to the upper frame portion 77.

[0343] The clip groove 116b may be open to both left and right directions. In addition, the fixing rib 77c of the upper frame portion 77 may also be formed in the left and right directions. The fixing rib 77c may be inserted from the front of the clip groove 116b to the inner side of the clip groove 116b. When the fixing rib 77c is inserted into the clip groove 116b, the first cover body 110 may be in the following manner: Fig.36 The upper frame portion 77 is fixed in the up-down direction, that is, the height direction, with reference to FIG.

[0344] In this state, the first cover body 110 can be assembled to the upper frame portion 77 using additional fasteners such as bolts. The first cover body 110 can be provided with a first fastening portion 117 independent of the fixing clip portion 116. The fastener can be assembled to the first fastening portion 117. Fig.34 As shown, a plurality of first fastening portions 117 may be disposed along the upper end portion of the first cover body 110 .

[0345] At this time, the first fastening portion 117 of the first cover body 110 can overlap with the second fastening portion 147 of the second cover body 140 and be assembled together using fasteners. Fig.29 The image acquisition module 100 may include a second cover body 140 located at a position corresponding to the first cover body 110 . Fig.36 The first fastening portion 117 and the second fastening portion 147 are overlapped with each other. In this state, the fastener can be assembled to the upper frame portion 77 after passing through the second fastening portion 147 and the first fastening portion 117 in sequence.

[0346] Fig.37 Another embodiment is shown, in which the first fastening portion 117 is provided on the first cover 110, but the second fastening portion 147 can be omitted on the second cover 140. Thus, only the first cover 110 can be assembled to the upper frame portion 77. Since the first cover 110 and the second cover 140 can be assembled to each other by fastening the hook 118 and the fastening protrusion 158, the entire module cover 110, 140 can be mounted on the upper frame portion 77 even without the second fastening portion 147.

[0347] Reference Fig.38 and Fig.39 , describing the first installation structure of the module cover 110, 140. Fig.38 and Fig.39 The structures of the first fastening portion 117 and the second fastening portion 147 are shown in an enlarged state. Fig.38 As shown, when the first fastening portion 117 of the first cover body 110 and the second fastening portion 147 of the second cover body 140 overlap each other, the first fastening hole 117a of the first fastening portion 117 and the second fastening hole 147a of the second fastening portion 147 may be connected to each other. In this state, the fastener may be assembled to the upper fastening portion 77b of the upper frame portion 77 after sequentially passing through the second fastening hole 147a and the first fastening hole 117a.

[0348] Reference Fig.39 , shows a situation where the first fastening hole 117a of the first cover body 110, the second fastening hole 147a of the second cover body 140, and the upper fastening hole 77b' of the upper fastening portion 77b are continuously connected to each other. The first fastening hole 117a, the second fastening hole 147a, and the upper fastening hole 77b' can be continuously arranged along the front-to-back direction (the left-right direction based on the figure).

[0349] At the same time, Fig.39As shown, the front side of the first cover 110 faces the back side of the second front panel G2a, and the surface of the first cover 110 can be bonded to the surface of the second front panel G2a by using an additional adhesive or adhesive tape. Fig.11 In the figure, K1 and K2 represent the areas where the front surface of the first cover body 110 and the back surface of the second front panel G2a are bonded.

[0350] Fig.40 and Fig.41 The second mounting structure of the module housings 110 and 140 is shown as an embodiment different from the above-mentioned embodiment. As shown in the figure, the first housing 110 is provided with the first fastening portion 117, but the structure assembled with the first fastening portion 117 can be omitted in the second housing 140. Therefore, only the first fastening portion 117 can be assembled with the upper fastening portion 77b.

[0351] Reference Fig.41 , the first fastening hole 117a of the first fastening part 117 can be arranged continuously with the upper fastening hole 77b' of the upper fastening part 77b. The fastener can be assembled sequentially through the first fastening hole 117a and the upper fastening hole 77b' that are continuous in this way. At this time, one end of the second cover body 140 can contact the lower end of the first fastening part 117. That is, one end of the second cover body 140 presses the lower end of the first fastening part 117, so that the assembly part of the second cover body 140 and the first cover body 110 can be closely attached.

[0352] Fig.42 and Fig.43 A third mounting structure of the module housings 110 and 140 is shown as an embodiment different from the above-mentioned embodiment. As shown in the figure, the second housing 140 is provided with a second fastening portion 147, but the structure assembled with the second fastening portion 147 can be omitted in the first housing 110. Therefore, only the second fastening portion 147 can be assembled to the upper fastening portion 77b.

[0353] Reference Fig.43, the second fastening hole 147a of the second fastening portion 147 can be arranged continuously with the upper fastening hole 77b' of the upper fastening portion 77b. The fastener can be assembled sequentially through the second fastening hole 147a and the upper fastening hole 77b' that are continuous in this way. At this time, since the upper part of the first cover body 110 is arranged between the upper part of the second cover body 140 and the upper frame part 77, when the fastener is assembled, the upper two surfaces of the first cover body 110 can be pressed by the second cover body 140 and the upper frame part 77 respectively. As a result, the first cover body 110, the second cover body 140 and the assembly part of the first cover body 110 can be firmly attached.

[0354] Figures 44 to 50 The assembly structure of the module housings 110 and 140 is shown. Here, the assembly structure of the module housings 110 and 140 refers to the structure used for assembling the first housing 110 and the second housing 140. Fig.44 The first cover body 110 may be provided with a fastening hook 118. The fastening protrusion 158 provided on the second cover body 140 may be inserted into the fastening hook 118. When the fastening protrusion 158 is inserted into the fastening hook 118, the second cover body 140 and the first cover body 110 may be combined with each other.

[0355] Reference Fig.30 The fastening hook 118 may protrude from the surface of the first cover body 110. The fastening hook 118 may protrude from the first cover body 110 toward the second cover body 140. In this embodiment, a plurality of the fastening hooks 118 are disposed on the first cover body 110. The plurality of the fastening hooks 118 may be spaced apart from each other.

[0356] The plurality of fastening hooks 118 may be disposed at a position closer to the lower end of the first cover 110 than the fixing clip portion 116. That is, the fastening hooks 118 may be disposed at a different height from the fixing clip portion 116 on the first cover 110. Thus, the fixing clip portion 116 and the fastening hooks 118 may be responsible for the installation of the module covers 110 and 140 and the assembly between the two covers at different heights.

[0357] Re-reference Fig.45 and Fig.46, the fastening hook 118 may include a pair of hook bodies 118a. The pair of hook bodies 118a may have structures that are symmetrical to each other. In the present embodiment, the pair of hook bodies 118a are cantilever structures with upper ends extending downward. The pair of hook bodies 118a are separated from each other, and a locking space 118b may be formed between them. During the process of inserting the fastening protrusion 158 of the second cover body 140 into the locking space 118b, the pair of hook bodies 118a may be elastically deformed in a direction away from each other.

[0358] For ease of description, the fastening protrusion 158 is first described. Fig.47 and Fig.48 1 shows the structure of the fastening protrusion 158. As shown in the figure, the fastening protrusion 158 may include a fastening base 158a protruding from the surface of the second cover body 140. The fastening base 158a may include a plurality of ribs protruding from the surface of the second cover body 140 and extending in two or more different directions. In this embodiment, the fastening base 158a is formed in a substantially T-shape. The fastening base 158a can improve the overall strength of the fastening protrusion 158 through such a structure.

[0359] The fastening base 158a may be provided with a convex body 158b. The convex body 158b may protrude from the fastening base 158a toward the first cover body 110. Fig.47 Based on the top view of FIG. 158 , the area of ​​the fastening base 158 a may be larger than the area of ​​the convex body 158 b. That is, it can also be considered that the convex body 158 b is formed only in a part of the fastening base 158 a.

[0360] A fastening head 158c may be provided at the end of the protrusion body 158b. The fastening head 158c may have a portion having a greater width than the protrusion body 158b. The fastening head 158c is a portion inserted between the pair of hook bodies 118a.

[0361] Fig.49 and Fig.50 FIG. 1 shows a state where the fastening protrusion 158 is coupled to the fastening hook 118. Fig.49 , shows a situation where the fastening head 158c of the fastening protrusion 158 is inserted between a pair of the hook bodies 118a. At this time, the inclined surface L1 of the hook body and the inclined surface L2 of the fastening head 158c can be formed to be parallel to each other, or inclined in the same direction.

[0362] like Fig.50As shown, if the fastening head 158c completely enters between the pair of hook bodies 118a, the pair of hook bodies 118a will be in a state of surrounding one end of the fastening head 158c. Therefore, the fastening head 158c can maintain the combined state and cannot move in the opposite direction, that is, the direction of detachment from the hook bodies 118a. As described above, in this embodiment, the first cover body 110 and the second cover body 140 can be assembled with each other without additional fasteners.

[0363] On the other hand, re-referencing Fig.29 A fastening piece 119 may be provided at the outer edge of the first cover body 110. The fastening piece 119 may be combined with a fastening arm 159 provided at the outer edge of the second cover body 140. When the end of the fastening arm 159 is inserted into the hole of the fastening piece 119, the second cover body 140 may be assembled to the first cover body 110.

[0364] As described above, the fastening piece 119 and the fastening arm 159 can play a role in assembling the first cover 110 and the second cover 140 together with the fastening hook 118 and the fastening protrusion 158. In this embodiment, the fastening piece 119 can be arranged at a position closer to the outside of the first cover 110 than the fastening hook 118. Similarly, the fastening arm 159 can be arranged at a position closer to the outside of the second cover 140 than the fastening protrusion 158.

[0365] like Fig.29 and Fig.30 As shown, the image sensing device 170 and the lighting device 180 may be installed on the first cover body 110. An image sensor mounting portion 121 for mounting the image sensing device 170 may be provided on the first cover body 110. An lighting mounting portion 125 for mounting the lighting device 180 may be provided on the first cover body 110. The image sensor mounting portion 121 and the lighting mounting portion 125 may be separated from each other. In this embodiment, it can also be considered that the module flow path portion R is provided at a position corresponding to between the image sensor mounting portion 121 and the lighting mounting portion 125.

[0366] As another example, the image sensor mounting portion 121 and the lighting mounting portion 125 may be separated from each other. In other words, the first cover body 110 may not be formed as a continuous body, and the image sensor mounting portion 121 and the lighting mounting portion 125 may be separated and formed as a plurality of bodies.

[0367] Observing the image sensor mounting portion 121, the image sensor mounting portion 121 may be disposed at the center of the first cover body 110. Thus, the image sensing device 170 mounted on the image sensor mounting portion 121 may face the center of the lower storage space 41. The image sensor mounting portion 121 may be disposed at a position close to the lower end of the first cover body 110. Thus, the image sensing device 170 mounted on the image sensor mounting portion 121 may be disposed closer to the lower storage space 41. As another example, the image sensor mounting portion 121 may also be disposed at a position deviated from the center of the first cover body 110, rather than at the center. As yet another example, the image sensor mounting portion 121 may also be disposed at the center or upper end of the first cover body 110, rather than at the lower end.

[0368] The image sensor mounting portion 121 may include a portion protruding from the surface of the first cover body 110 and a portion relatively recessed due to the protruding portion. As described above, the recessed portion of the image sensor mounting portion 121 may accommodate the image sensing device 170. Fig.30 The situation described above is shown.

[0369] Reference Figure 51 to Figure 54 , the image sensor mounting portion 121 is described in detail. Fig.51 The image sensing device 170 is shown as being installed in the image sensor installation portion 121. In the figure, the image sensing device 170 is exposed, but the second cover body 140 is assembled in front of the image sensing device 170, so that the rest of the image sensing device 170 except the image sensor 175 of the image sensing device 170 can be shielded. The image sensor 175 can also be shielded by a sensor protection cover 178 described later.

[0370] The image sensor mounting portion 121 may be provided with a sensor hook 122. The sensor hook 122 may lock and fix the sensor substrate 171 constituting the image sensing device 170. The sensor hook 122 may protrude from the upper end of the image sensor mounting portion 121.

[0371] For the sake of convenience, the structure of the image sensing device 170 is first described. The image sensing device 170 may include a sensor substrate 171 and an image sensor 175 mounted on the sensor substrate 171. The image sensor 175 may acquire an image through a lens. Here, the image sensor 175 may be a CCD (Charge Coupled Device) image sensor or a CMOS (Complementary Metal Oxide Semiconductor) image sensor that converts an optical signal into an electrical signal. The sensor protection cover 178 described later may also be regarded as a part of the image sensing device 170.

[0372] The sensor substrate 171 can be connected to the connecting wire W2 to receive power. The image information acquired by the image sensor 175 can also be transmitted to the control unit 21, 23, 25 through the connecting wire W2. At this time, since the connecting wire W2 is connected to the connector module 200, it can also be regarded that the sensor substrate 171 is connected to the main control unit through the connector module 200.

[0373] When observing the image sensor installation portion 121, a sensor installation fence 123 (see Fig.52 ). The sensor installation fence 123 may protrude from the surface 111a of the installation plate 111. The sensor installation fence 123 may be configured to surround a space where the image sensing device 170 is configured. The sensor installation fence 123 may also be regarded as a structure surrounding the image sensing device 170.

[0374] like Fig.52 As shown, the sensor installation fence 123 may have a structure that is less protruding than the lens 176 of the image sensor 175 constituting the image sensing device 170. This is to avoid interference between the sensor installation fence 123 and the image sensor 175 in viewing angle.

[0375] The sensor installation fence 123 may include a main fence 123a in a substantially square shape. The main fence 123a may surround the upper portion of the sensor substrate 171. The sensor hook 122 may be disposed on the main fence 123a.

[0376] The sensor installation fence 123 may be provided with a first sensor guide 123b. The first sensor guide 123b may protrude from the lower side of the main fence 123a in the same direction as the main fence 123a. The first sensor guide 123b may support both sides of the lower end of the sensor substrate 171 respectively. The first sensor guide 123b may support the lower end of the image sensing device 170 to guide the installation direction of the image sensing device 170.

[0377] The sensor installation fence 123 may be provided with a second sensor guide 123c. The second sensor guide 123c may protrude in the same direction as the main fence 123a at a position higher than the first sensor guide 123b. The second sensor guide 123c may respectively support both sides of the center of the sensor substrate 171. The second sensor guide 123c may respectively support both sides of the center of the image sensing device 170, and guide the setting direction of the image sensing device 170 together with the first sensor guide 123b. At this time, the first sensor guide 123b and the second sensor guide 123c may also be regarded as part of the sensor installation fence 123.

[0378] The sensor installation fence 123 may be provided with sensor tilt guides 124a and 124b. The sensor tilt guides 124a and 124b may enable the image sensing device 170 to be installed on the image sensor installation portion 121 at a tilted state at a predetermined angle, more precisely, at a downward tilted angle. Fig.51 The sensor tilt guides 124a and 124b have an inclined surface structure and can tiltably support the bottom surface of the sensor substrate 171. In this embodiment, the sensor tilt guides 124a and 124b can include two sensor tilt guides 124a and 124b. The first sensor tilt guide 124a and the second sensor tilt guide 124b can support the sensor substrate 171 at different heights.

[0379] Reference Fig.52 , showing a situation where the image sensing device 170 is installed at an inclined angle. The image sensing device 170 can be configured to be tilted downward by α1 degrees with respect to the vertical direction. Here, the downward tilt direction refers to the direction of the image sensing device 170 being tilted downward by α1 degrees with respect to the vertical direction. Fig.52 For this purpose, the sensor installation fence 123 may be provided with the first sensor tilt guide 124 a and the second sensor tilt guide 124 b supporting the sensor substrate 171 .

[0380] Referring to the cross-sectional view Fig.53 , Fig.53 is from Fig.52 The image sensing device 170 is observed from the opposite side. As shown in the figure, the upper end of the sensor substrate 171 constituting the image sensing device 170 can be locked and fixed to the sensor hook 122. Fig.53 , but the back surface of the sensor substrate 171 may be supported in an inclined direction by the aforementioned first sensor tilt guide 124a and the second sensor tilt guide 124b.

[0381] For the sake of convenience, the sensor protection cover 178 will be described first. The sensor protection cover 178 may be arranged in front of the lens 176 provided on the image sensor 175. The sensor protection cover 178 may be arranged at a predetermined distance from the lens 176. The sensor protection cover 178 may protect the image sensor 175 including the lens 176. The sensor protection cover 178 may play a shielding function to prevent the heat of the second storage space 41 from being directly transferred to the image sensor 175. In addition, the sensor protection cover 178 may also prevent foreign matter from contacting the lens 176.

[0382] In this embodiment, the sensor protection cover 178 may be arranged in an inclined direction and parallel to the image sensor 175. More specifically, when the first cover 110 and the second cover 140 are assembled, the image sensor 175 and the sensor protection cover 178 may be arranged facing each other.

[0383] The sensor protection cover 178 may be made of a transparent plate-like material. The sensor protection cover 178 may be disposed on the second cover body 140. An inclined plate 143 may be disposed on the sensor cover portion 142 of the second cover body 140. A portion of the front surface of the sensor protection cover 178 may be closely attached to the back surface of the inclined plate 143.

[0384] The upper end of the sensor protection cover 178 can be locked on the cover hook arm 143a provided on the second cover body 140. The cover hook arm 143a can lock the upper end of the sensor protection cover 178 to prevent the upper end of the sensor protection cover 178 from being Fig.53 Separate in clockwise direction. Fig.55 The cover hook arm 143 a can lock the central portion of the upper end portion of the sensor protection cover 178 .

[0385] In addition, cover guide ends 143b may be provided at the lower ends of both sides of the sensor protection cover 178. The cover guide ends 143b may be provided at the second housing 140. The cover guide ends 143b may support the lower ends of both sides of the sensor protection cover 178 to prevent the sensor protection cover 178 from being separated. Fig.54 The sensor protection cover 178 can be supported by the cover guide end 143b to be rotated counterclockwise by a specified angle based on the vertical direction.

[0386] At this time, the cover guide end 143b can simultaneously support two different surfaces of the sensor protection cover 178. In this embodiment, the cover guide end 143b has a substantially The cross section of the U-shaped cover 178 can simultaneously support two different surfaces of the sensor protection cover 178. In addition, the sensor protection cover 178 can be slidably coupled between a pair of the cover guide ends 143b.

[0387] Reference Fig.54 The second surface 178b of the sensor protection cover 178 facing the lens 176 of the image sensor 175 is arranged to face a portion of the cover guide end 143b, and the second surface 178b of the sensor protection cover 178 and the cover guide end 143b may be separated from each other by a predetermined distance x. Thus, when the sensor protection cover 178 is slidably coupled between the pair of cover guide ends 143b, a large fastening force is not required.

[0388] The pair of cover guide ends 143b may be disposed at a cover assembly entrance portion 143d (see Fig.55 ) on both sides. Thus, the pair of cover guide ends 143b can guide the sensor protection cover 178 at the initial stage of assembly when one end portion 178c of the sensor protection cover 178 is inserted through the inlet portion 143d.

[0389] The lower end of the sensor protection cover 178 may be locked at the cover hook end 143c. The cover hook end 143c may be provided on the second cover body 140. The cover hook end 143c supports the lower end of the sensor protection cover 178, and can prevent the sensor protection cover 178 from being Fig.55 The protruding height of the cover hook end 143 c is relatively low, so that when the sensor protection cover 178 is installed on the second cover body 140 , it can go over the cover hook end 143 c.

[0390] At this time, if Fig.53As shown, the first cover body 110 may be provided with a cover support end 123d supporting the second end 178d of the sensor protection cover 178 on the opposite side of the first end 178c of the sensor protection cover 178. The cover support end 123d may protrude from the surface of the first cover body 110 toward the surface of the second cover body 140. When the first cover body 110 and the second cover body 140 are assembled with each other, the cover support end 123d may be arranged at the lower part of the cover hook end 143c.

[0391] The cover assembly entrance 143d may be open in the up-down direction, which is the height direction of the lower door panel G2. In addition, the cover hook end 143c may be disposed at the entrance 143d. Therefore, in the initial stage of assembly when the end 178c of the sensor protection cover 178 is inserted through the entrance 143d, the end 178c of the sensor protection cover 178 may pass over the cover hook end 143c.

[0392] At this time, the overlapping height of the cover hook end 143c and the other end 178d of the sensor protection cover 178 may be smaller than the overlapping height of the cover support end 123d and the other end 178d of the sensor protection cover 178. Thus, in the initial stage of assembly when the one end 178c of the sensor protection cover 178 is inserted through the inlet 143d, the one end 178c of the sensor protection cover 178 can easily pass over the cover hook end 143c. However, when the two cover bodies 110 and 140 are assembled to each other, the cover support end 123d stops the other end 178d of the sensor protection cover 178, and the separation of the sensor protection cover 178 can be prevented.

[0393] Reference Fig.56 , shows a lighting installation part 125 provided on the installation plate 111 of the first cover body 110. As shown in the figure, the lighting installation part 125 may include a first lighting installation part 125A and a second lighting installation part 125B. The first lighting installation part 125A may be provided with the first lighting part 180a, and the second lighting installation part 180b may be provided with the second lighting installation part 125B. The first lighting installation part 125A and the second lighting installation part 125B may be separated along a first direction, that is, a left-right direction.

[0394] Observing the first lighting installation part 125A, the first lighting installation part 125A may be arranged at a position relatively closer to the image sensor installation part 121 than the second lighting installation part 125B. The first lighting part 180a may be installed on the first lighting installation part 125A. In a state where the first lighting part 180a is installed on the first lighting installation part 125A, if the second cover body 140 is assembled to the first cover body 110, the second cover body 140 may shield the first lighting part 180a. Since the first cover plate 190a described later is arranged on the second cover body 140, the light emitting device 183 of the first lighting part 180a may illuminate the lower storage space 41 through the first cover plate 190a.

[0395] When observing the structure of the first lighting mounting portion 125A, a first cover support arm 126a may be provided at the first lighting mounting portion 125A. The first cover support arm 126a may protrude from the first lighting mounting portion 125A toward the second cover body 140. The first cover support arm 126a may clamp one end portion of the first cover plate 190a to prevent the first cover plate 190a from being separated from the second cover body 140. The first cover plate 190a is first installed on the second cover body 140 and can be relatively easily detached in the direction opposite to the assembly direction. However, in the case where the first cover body 110 is assembled with the second cover body 140, the first cover support arm 126a of the first cover body 110 clamps one end portion of the first cover plate 190a to prevent the first cover plate 190a from being detached in the direction opposite to the assembly direction. Refer to Fig.69 and Fig.70 , it can be seen that the first cover support arm 126a protrudes to a position facing one end of the first cover plate 190a.

[0396] Re-reference Fig.56 The first lighting installation portion 125A may be provided with a first lighting hook 127a. The first lighting hook 127a may be locked and fixed to the lighting substrate 181 constituting the first lighting portion 180a. The first lighting hook 127a has a substantially cantilever structure, and one end thereof may be locked to the edge of the lighting substrate 181. The first lighting hook 127a may protrude from the upper end of the first lighting installation portion 125A in a cantilever structure.

[0397] For the sake of convenience, the lighting device 180 is first described. The first lighting unit 180a and the second lighting unit 180b constituting the lighting device 180 may have the same structure. The first lighting unit 180a is used as a reference for description. Fig.56As shown, the first lighting unit 180a may include a lighting substrate 181 and a light emitting device 183 mounted on the lighting substrate 181. The light emitting device 183 may be a component that uses a power source to irradiate light, such as LED lighting. As another example, the first lighting unit 180a and the second lighting unit 180b may also have a structure connected to each other. For example, the first lighting unit 180a and the second lighting unit 180b may also share a lighting substrate 181. In addition, the cover plate 190 described later may also be regarded as a part of the components constituting the lighting device 180.

[0398] Looking again at the first lighting mounting portion 125A, a first lower locking platform 128a1 can be provided at the lower portion of the first lighting mounting portion 125A. The first lower locking platform 128a1 can lock the lower end of the lighting substrate 181. The first lower locking platform 128a1 can prevent the first lighting portion 180a from separating forward with reference to the figure. As a result, the upper end of the lighting substrate 181 is locked by the first lighting hook 127a, and the lower end thereof is locked by the first lower locking platform 128a1. When installing the first lighting portion 180a, it is only necessary to first lock the lower end of the lighting substrate 181 to the first lower locking platform 128a1, and then rotate the upper end of the lighting substrate 181 to make it pass over the first lighting hook 127a.

[0399] The first lighting installation portion 125A may be provided with a first lighting guide fence 128b1. The first lighting guide fence 128b1 may be provided on both sides of the first lighting installation portion 125A, respectively. The first lighting guide fence 128b1 may support the two side surfaces of the lighting substrate 181 constituting the first lighting portion 180a. The aforementioned first cover support arm 126a may be regarded as a structure further protruding from the first lighting guide fence 128b1. Alternatively, the first cover support arm 126a may also be regarded as a part of the first lighting guide fence 128b1.

[0400] Although not shown in the figure, the first lighting installation part 125A may also be provided with an angle adjustment part for adjusting the installation angle of the first lighting part 180a. The angle adjustment part may also be formed as an inclined surface in the first lighting guide fence 128b1. The angle adjustment part may support the lighting substrate 181 of the first lighting part 180a so that the first lighting part 180a faces the center of the lower storage space 41. In this embodiment, the angle adjustment part is omitted, and the first lighting installation part 125A is configured so that its front side faces the lower storage space 41. That is, the first lighting installation part 125A is Fig.56 The reference point is toward the right.

[0401] Next, the second lighting installation portion 125B is described. The second lighting installation portion 125B can be arranged at a position relatively farther from the image sensor installation portion 121 than the first lighting installation portion 125A. A second lighting portion 180b can be installed on the second lighting installation portion 125B. In a state where the second lighting portion 180b is installed on the second lighting installation portion 125B, if the second cover body 140 is assembled to the first cover body 110, the second cover body 140 can shield the second lighting portion 180b. Since the second cover plate 190b described later is arranged on the second cover body 140, the light emitting device 183 of the second lighting portion 180b can illuminate the lower storage space 41 through the second cover plate 190b.

[0402] When observing the structure of the second lighting installation part 125B, the second lighting installation part 125B may be provided with a second cover support arm 126b. Fig.69 and Fig.70 As shown, the second cover support arm 126b can protrude from the second lighting mounting portion 125B toward the second cover body 140. The second cover support arm 126b can lock one end of the second cover plate 190b to prevent the second cover plate 190b from being separated from the second cover body 140. The second cover plate 190b is first installed on the second cover body 140, and can be relatively easily detached in the direction opposite to the assembly direction. However, in the case where the first cover body 110 and the second cover body 140 are assembled, the second cover support arm 126b of the first cover body 110 locks one end of the second cover plate 190b to prevent the cover plate 190 from being detached in the direction opposite to the assembly direction. For reference, in Fig.56 In the figure, the second cover support arm 126b is not shown due to the angle relationship.

[0403] Re-reference Fig.56 The second lighting installation part 125B may be provided with a second lighting hook 127b. The second lighting hook 127b may be used to lock and fix the lighting substrate 181 constituting the second lighting part 180b. The second lighting hook 127b has a substantially cantilever structure, and one end thereof may be used to lock the edge of the lighting substrate 181. The second lighting hook 127b may protrude from the upper end of the second lighting installation part 125B in a cantilever structure.

[0404] A second lower stopper 128a2 may be provided at the lower portion of the second lighting mounting portion 125B. The second lower stopper 128a2 may stop the lower end of the lighting substrate 181. The second lower stopper 128a2 can prevent the second lighting portion 180b from separating forward with reference to the figure. As a result, the upper end of the lighting substrate 181 is stopped by the second lighting hook 127b, and the lower end thereof is stopped by the second lower stopper 128a2. When installing the second lighting portion 180b, it is only necessary to first stop the lower end of the lighting substrate 181 on the second lower stopper 128a2, and then rotate the upper end of the lighting substrate 181 to make it pass over the second lighting hook 127b.

[0405] The second lighting installation portion 125B may be provided with a second lighting guide fence 128b2. The second lighting guide fence 128b2 may be provided on both sides of the second lighting installation portion 125B, respectively. The second lighting guide fence 128b2 may support the two side surfaces of the lighting substrate 181 constituting the second lighting portion 180b. The aforementioned second cover support arm 126b may be regarded as a structure further protruding from the second lighting guide fence 128b2. Alternatively, the second cover support arm 126b may also be regarded as a part of the second lighting guide fence 128b2.

[0406] The second lighting installation portion 125B may also be provided with a lighting angle adjustment portion 129 for adjusting the installation angle of the second lighting portion 180b. The lighting angle adjustment portion 129 may also be formed as an inclined surface on the second lighting guide fence 128b2. The lighting angle adjustment portion 129 may support the lighting substrate 181 of the second lighting portion 180b so that the second lighting portion 180b faces the center of the lower storage space 41.

[0407] More specifically, the illumination angle adjustment unit 129 may support the illumination substrate 181 of the second illumination unit 180b to be tilted downward. When the illumination angle adjustment unit 129 supports the back surface of the illumination substrate 181 in an inclined direction, the entire second illumination unit 180b may have an angle tilted downward. Fig.57 , showing a situation where the second lighting unit 180b is installed tilted downward. As shown in the figure, the lighting angle adjustment unit 129 supports the back of the lighting substrate 181 so that the second lighting unit 180b is configured to be tilted downward by α2 degrees with respect to the vertical direction. Here, the tilted downward direction refers to the direction of the second lighting unit 180b tilted downward by α2 degrees with respect to the vertical direction. Fig.57As a reference, the direction of rotation is clockwise. Thus, the irradiation angle of the light emitted by the second lighting unit 180b can be tilted downward by α2 degrees. For reference, the α2 degree can be different from the above-mentioned α1 degree as the tilt angle of the image acquisition device 170. In this embodiment, the α2 degree is less than α1 degree.

[0408] On the other hand, Fig.30 As shown, the first cover 110 may include the first connection body 130. The connection wire W2 may be accommodated in the first connection body 130. A wire connection portion 130a may be formed open at the lower portion of the first connection body 130 so that the connection wire W2 extends outward.

[0409] The first connection body 130 may be provided with a connection wire holder 135 having a structure similar to the wire holder 115. The connection wire holder 135 may guide the connection wire W2 in a direction different from that of the wire holder 115, more precisely, in a vertical direction.

[0410] In addition, the first connecting body 130 may include a connecting fastening hook 138 having the same structure as the fastening hook 118. The connecting fastening hook 138 may be connected to the connecting fastening protrusion 158 (refer to FIG. 158 ) of the second cover body 140. Fig.59 Since the connection fastening hook 138 has the same structure as the fastening hook 118, detailed description thereof will be omitted.

[0411] At this time, the connection fastening hook 138 and the connection wire holding member 135 can be arranged to be spaced apart from each other in the left and right directions based on the up-down direction, that is, the second direction. Fig.30 The connection fastening hook 138 is arranged at a relatively left position relative to the connection wire holder 135. This is to guide the connection wire W2 to a relatively right position inside the first connection body 140. In addition, when the connection fastening hook 138 and the connection wire holder 135 are arranged as described above, Fig.31 As shown, the connection fastening hook 138 itself can also play a role in guiding the connecting wire W2.

[0412] Similar to the fastening piece 119, reference numeral 139 indicates a fastening piece structure for assembling the two housings 110 and 140. The fastening piece 139 can be connected to a fastening arm 159 (see Fig.59 When the end of the fastening arm 159 is inserted into the hole of the fastening piece 139 , the second cover body 140 can be assembled to the first cover body 110 .

[0413] Next refer to Fig.58 , the structure of the second cover 140 is described. The second cover 140 can constitute the module cover 110, 140 together with the first cover 110. The second cover 140 has a structure corresponding to the first cover 110 and can be assembled with the first cover 110.

[0414] The second cover body 140 may be arranged in a plurality of directions different from each other. In this embodiment, the portion of the second cover body 140 formed in the first direction and the portion formed in the second direction are connected to each other. Here, the portion formed in the first direction is the cover body 141, and the portion formed in the second direction is the second connection body 160. As another example, the second cover body 140 may also be formed only in the first direction or the second direction.

[0415] The second cover 140 may have a generally thin plate-like structure. One side of the second cover 140 may face the first cover 110, and the other side may face the second inner panel G2b. At this time, one side of the second cover 140 may shield the image sensing device 170 and the lighting device 180. The image sensing device 170 and the lighting device 180 are first arranged on the first cover 110, and then the second cover 140 is combined with the first cover 110, so as to shield the image sensing device 170 and the lighting device 180.

[0416] The cover body 141 may be provided with a sensor cover 142 and an illumination cover 151. The sensor cover 142 is disposed in front of the image sensor mounting portion 121 of the first cover body 110 and may cover the image sensor mounting portion 121. Thus, the portion of the image sensing device 170 disposed in the image sensor mounting portion 121 other than the lens may be shielded by the sensor cover 142. Of course, if the sensor protection cover 178 is disposed in the second cover body 140 as described above, the lens of the image sensing device 170 is also shielded.

[0417] As another example, the sensor cover 142 and the lighting cover 151 may be separated from each other. In other words, the second cover body 140 may not be formed as a continuous main body, and the sensor cover 142 and the lighting cover 151 may be separated and formed as a plurality of main bodies.

[0418] The sensor cover 142 may be disposed at the center of the cover body 141. A pair of illumination covers 151 may be disposed on both sides of the sensor cover 142 with the sensor cover 142 as the center. As another example, the sensor cover 142 may be disposed at a position on either side of the cover body 141, which is biased to the left or right side, instead of the center. As another example, a plurality of sensor covers 142 may also be provided on the cover body 141.

[0419] The module flow path portion R may be provided between the sensor cover portion 142 and the lighting cover portion 151. The module flow path portion R may be formed in a shape that is recessed in the second cover body 140 corresponding to the portion between the sensor cover portion 142 and the lighting cover portion 151. The module flow path portion R may be regarded as a structure in which a portion of the second cover body 140 is recessed toward the first cover body 110.

[0420] The sensor cover 142 is described. A sensing hole 142a may be formed in the sensor cover 142. The sensing hole 142a may be disposed in front of the lens of the image sensing device 170. The sensing hole 142a may maintain a through structure, or the sensor protection cover 178 may cover the sensing hole 142a. The sensing hole 142a may be disposed on the lower side of the sensor cover 142.

[0421] More precisely, the sensor cover 142 may be provided with an inclined plate 143. In this embodiment, the inclined plate 143 is a plate-like structure obliquely formed at the lower portion of the sensor cover 142. A portion of the front surface of the sensor protection cover 178 may be closely attached to the back surface of the inclined plate 143. The sensing hole 142a may also be provided on the inclined plate 143.

[0422] The inclined plate 143 may have a structure that is inclined downward toward the bottom of the lower storage space 41. The inclined plate 143 is arranged on the second cooling flow path A2, and may interfere with the air flowing in the second cooling flow path A2. The image sensing device 170, which generates relatively large amounts of heat, may be arranged in a direction that narrows the second cooling flow path A2 through the inclined plate 143. The contact area between the inclined plate 143 and the outside air becomes larger, thereby enabling effective cooling. As a result, heat dissipation of the image sensing device 170 arranged inside the inclined plate 143 can also be effectively achieved. The surface of the inclined plate 143 may also be regarded as a heat dissipation surface.

[0423] Reference Fig.59In order to effectively cool the image sensing device 170, sensor cooling holes 142b may be formed open on both sides of the inclined plate 143. The sensor cooling holes 142b may be formed through the inclined plate 143. The sensor cooling holes 142b may be respectively arranged on both sides with the sensing hole 142a as the center. The sensor cooling holes 142b may be opened in a direction different from that of the sensing hole 142a, more precisely, in a side direction.

[0424] The cover body 141 may be provided with a second fastening portion 147. The second fastening portion 147 may be provided at an upper end portion of the cover body 141. The second fastening portion 147 may be disposed at a position corresponding to the first fastening portion 117 of the first cover body 110. The second fastening portion 147 may be assembled to the upper frame portion 77 together with the first fastening portion 117.

[0425] Reference numeral 147' denotes an auxiliary fastening portion. The auxiliary fastening portion 147' may be disposed at a position different from that of the second fastening portion 147. In the present embodiment, the auxiliary fastening portions 147' are disposed on both sides of the cover body 141. The auxiliary fastening portion 147' may be longer than the second fastening portion 147. Thus, the auxiliary fastening portion 147' may be assembled to the upper frame portion 77 at a different height from that of the second fastening portion 147. As another example, the auxiliary fastening portion 147' may also be omitted.

[0426] Reference Fig.60 and Fig.61 The second cover body 140 may be provided with a supporting protrusion 149. The supporting protrusion 149 may protrude from the surface of the second cover body 140 toward the inner frame portion 90. The supporting protrusion 149 may have a substantially cylindrical shape. The supporting protrusions 149 may be provided on both sides of the second cover body 140, respectively.

[0427] In this embodiment, the supporting protrusion 149 protrudes from the first surface of the image acquisition module 100, and the second surface of the image acquisition module 100 formed on the opposite side of the first surface is closely attached to the surface of any one of the plurality of panels, namely, the second front panel G2a. In other words, it can be regarded that the supporting protrusion 149 protrudes in the direction opposite to the adhesive surface of the image acquisition module 100. At this time, the second surface of the image acquisition module 100 can be attached to the surface of the front panel G2a arranged at the frontmost position among the plurality of panels. Fig.11 In FIG. 1 , such bonding surfaces are shown by K1 and K2.

[0428] At this time, the first surface of the image acquisition module 100 can be located behind the second surface based on the front-to-back direction of the plurality of panels. That is, the supporting protrusion 149 is arranged behind the adhesive surfaces K1 and K2. The supporting protrusion 149 can prevent deformation at a position away from the adhesive surfaces K1 and K2.

[0429] The support protrusion 149 may be provided at a position facing the anti-deformation portion 99 of the inner frame portion 90. The support protrusion 149 and the anti-deformation portion 99 may protrude in directions facing each other. That is, the anti-deformation portion 99 may protrude in a direction facing the support protrusion 149. In the case where the module cover bodies 110 and 140 are deformed due to conditions such as high temperature, the support protrusion 149 is in contact with the anti-deformation portion 99 to prevent the module cover bodies 110 and 140 from being excessively deformed.

[0430] Reference Fig.61 As shown in (a), the protruding length of the support protrusion 149 is greater than the protruding length of the anti-deformation portion 99. The support protrusion 149 can be made of injection molding, and it is easier to realize the shape than the anti-deformation portion 99. Therefore, when the support protrusion 149 is formed to be longer than the anti-deformation portion 99, the processing of the inner frame portion 90 can be relatively easy.

[0431] At this time, the cross-sectional area of ​​the anti-deformation portion 99 may be larger than the cross-sectional area of ​​the supporting protrusion 149. Thus, even if the position of the supporting protrusion 149 changes due to the deformation of the image acquisition module 100, the end portion 149a of the supporting protrusion 149 may contact the surface 99a of the anti-deformation portion 99, thereby stably realizing the deformation prevention function.

[0432] like Fig.60 A magnified image of Fig.61 As shown in (a), the support protrusion 149 may protrude to a position separated by a predetermined distance from the anti-deformation portion 99. More precisely, the first support surface 99a of the anti-deformation portion 99 may be separated by a predetermined distance from the second support surface 149a of the support protrusion 149. As described above, the intervals separated from each other gradually shorten as the module cover bodies 110 and 140 are deformed, and finally the first support surface 99a and the second support surface 149a contact each other, so that the module cover bodies 110 and 140 will not be further deformed.

[0433] In addition, when the first support surface 99a as the terminal portion of the anti-deformation portion 99 and the second support surface 149a of the support protrusion 149 are spaced apart, the vibration generated during the normal operation of the door can be reduced from being transmitted toward the image acquisition module 100.

[0434] As another example, refer to Fig.61 (b), the image acquisition module 100 may be provided with a support protrusion 149, and the anti-deformation portion 99 may be omitted in the inner frame portion 90. In this case, the length of the support protrusion 149 may be greater than that of the aforementioned embodiment (refer to Fig.61 (a)) of the support protrusion 149. In addition, refer to Fig.61 (c), the support protrusion 149 can be omitted in the image acquisition module 100, and the anti-deformation portion 99 can be provided in the inner frame portion 90. In this case, the length of the anti-deformation portion 99 can be greater than that of the aforementioned embodiment (refer to Fig.61 As another example, the inner frame portion 90 may be provided with a support protrusion 149, and the image acquisition module 100 may be provided with an anti-deformation portion 99.

[0435] Reference Fig.62 , a lighting cover portion 151 may be provided on the cover body 141. The lighting cover portion 151 covers the lighting portion so that the lighting portion is not exposed. The lighting cover portion 151 may shield both the first lighting portion 180a and the second lighting portion 180b. To this end, the lighting cover portion 151 may include a first lighting cover portion 151A covering the first lighting portion 180a and a second lighting cover portion 151B covering the second lighting portion 180b.

[0436] The first lighting cover portion 151A and the second lighting cover portion 151B may each be opened to form a cover hole 153. The cover plate 190 may be disposed in the cover hole 153. In this embodiment, the cover hole 153 includes a first cover hole 153a and a second cover hole 153b, and the first cover hole 153a and the second cover hole 153b may be respectively disposed with a first cover plate 190a and a second cover plate 190b.

[0437] Reference Fig.63 The first lighting cover 151A may be disposed at a boundary portion of the module flow path portion R. The first lighting cover 151A may be disposed along an inclined direction. More specifically, the first lighting cover 151A may have a vertical direction (height direction, Figure 1 The first lighting cover 151A is rotated by a predetermined angle with respect to an axis extending in the Z-axis direction of the lower storage space 41 as a reference, rather than facing the main body 10 of the home appliance from the front. In this embodiment, the first lighting cover 151A can be twisted toward the center of the lower storage space 41.

[0438] Reference Fig.64 The first lighting cover 151A is arranged along the up-down direction (height direction, Figure 1The first cover plate 190a disposed on the first lighting cover portion 151A may be twisted in the counterclockwise direction by β degrees based on a vertical line extending in the Z-axis direction of the first lighting cover portion 151A. Thus, the first cover plate 190a disposed on the first lighting cover portion 151A may also be twisted in the counterclockwise direction by β degrees based on the vertical line. When the first cover plate 190a is disposed in an inclined direction, the light of the first lighting portion 180a irradiated by the first cover plate 190a may be diffused in the direction in which the first cover plate 190a is inclined. In this embodiment, the β degree is the same as the aforementioned α2.

[0439] The second lighting cover portion 151B may be disposed outside the first lighting cover portion 151A, that is, may be disposed close to the end portion of the cover body 141. The second lighting cover portion 151B may protrude further toward the main body 10 of the household appliance than the module flow path portion R together with the first lighting cover portion 151A. Thus, the first lighting cover portion 151A and the second lighting cover portion 151B may form a bottleneck area BN in the second cooling flow path A2.

[0440] Reference Fig.63 The second lighting cover portion 151B may be formed to be inclined in a direction different from that of the first lighting cover portion 151A. More specifically, the second lighting cover portion 151B may have a shape that is inclined in the left-right direction ( Figure 1 The second lighting cover 151B is rotated by a predetermined angle based on the Y-axis direction (ie, the axis extending in the longitudinal direction of the second cover body 140) instead of facing the main body 10 of the household appliance. In this embodiment, the second lighting cover 151B can be twisted toward the center of the lower storage space 41.

[0441] Reference Fig.65 The second lighting cover portion 151B is arranged along the left-right direction ( Figure 1 The second cover plate 190b disposed on the second lighting cover portion 151B may be twisted clockwise by α2 degrees based on a horizontal line extending in the Y-axis direction of the second lighting cover portion 151B. Thus, the second cover plate 190b disposed on the second lighting cover portion 151B may also be twisted counterclockwise by α2 degrees based on the horizontal line. When the second cover plate 190b is disposed in an inclined direction, the light of the second lighting portion 180b irradiated by the second cover plate 190b may be diffused in the direction in which the second cover plate 190b is inclined.

[0442] Reference Fig.66The second lighting cover portion 151B may be provided with a lighting guide surface 154. The lighting guide surface 154 may form an inclined surface structure on both sides of the second cover hole 153b with the second cover hole 153b for the second cover plate 190b to be installed as the center. The lighting guide surface 154 may guide the direction in which the light irradiated from the second lighting portion 180b diffuses. In order to effectively diffuse and reflect the light, a reflective coating portion may also be provided on the lighting guide surface 154.

[0443] exist Fig.67 and Fig.68 The structure in which the cover plate 190 is installed on the lighting cover portion 151 is shown. For reference, since the installation structures of the cover plate 190 of the first lighting cover portion 151A and the second lighting cover portion 151B are similar, the same reference numerals are given. Fig.67 The cover body 141 is shown as viewed from the upper side thereof.

[0444] For the sake of convenience, the structure of the cover plate 190 is first described. The first surface 190a1 of the cover plate 190 can face the storage space 31, 41 as the front, and the second surface 190a2 as the opposite side can face the second front panel G2a as the rear. In addition, one end 190a3 of the two ends of the cover plate 190 becomes the front part when the cover plate 190 is installed on the lighting cover part 151, and the other end 190a4 becomes the rear part when the cover plate 190 is installed on the lighting cover part 151.

[0445] Taking the first lighting cover 151A as a reference, the first lighting cover 151A may be provided with cover stoppers 155a for respectively stopping the two side surfaces of the first cover plate 190a. The pair of cover stoppers 155a facing each other may respectively stop and fix the opposite sides of the first cover plate 190a. The cover stoppers 155a may have a substantially Thus, the cover stopper 155a can support two different surfaces of the first cover plate 190a. In this embodiment, the cover stopper 155a can support the top surface and the side surface of the first cover plate 190a to guide the sliding of the first cover plate 190a.

[0446] In addition, a cover stopper 155b may be provided on the side of the end 190a3 of the first cover plate 190a that cannot be supported by the pair of cover stopper portions 155a. The cover stopper 155b is a portion that stops the end 190a3 when the first cover plate 190a is inserted to the deepest.

[0447] In addition, a pre-assembly protrusion 155c may be provided on the other end 190a4 side of the first cover plate 190a where the pair of the cover stopper 155a and the cover stopper 155b are not provided. The pre-assembly protrusion 155c may be provided at the entrance where the first cover plate 190a is installed to the first lighting cover part 151A. Since the protrusion height of the pre-assembly protrusion 155c is not high, the one end 190a3 of the first cover plate 190a may be installed on the first lighting cover part 151A over the pre-assembly protrusion 155c.

[0448] exist Fig.67 and Fig.68 The first cover plate 190a and the second cover plate 190b indicated by dotted lines refer to the state before installation. Fig.67 In the direction of the arrows, the first cover plate 190a and the second cover plate 190b can be installed to the first lighting cover portion 151A and the second lighting cover portion 151B, respectively.

[0449] At this time, since the height of the pre-assembly protrusion 155c is not high, there is a risk that the other end 190a4 of the first cover plate 190a may go over the pre-assembly protrusion 155c again in the opposite direction and separate. In order to prevent this, as described above, the first cover body 110 may be provided with a first cover support arm 126a. Fig.69 It can be observed that the first cover support arm 126a supports one end of the first cover plate 190a, that is, the other end 190a4. It can also be considered that the first cover support arm 126a makes up for the locking function of the pre-assembly protrusion 155c. In this embodiment, the protruding height of the pre-assembly protrusion 155c is lower than that of the cover locking portion 155a.

[0450] The length between the two ends of the first cover plate 190a, i.e., one end 190a3 and the other end 190a4, is shorter than the distance between the cover stopper 155b and the pre-assembly protrusion 155c. Thus, the first cover plate 190a can be easily installed between the cover stopper 155a and the pre-assembly protrusion 155c.

[0451] Configured in Fig.69 The other end 190b4 of the second cover plate 190b on the left side can be locked and fixed by the second cover support arm 126b. The second cover support arm 126b locks the other end 190b4 of the second cover plate 190b, thereby also compensating for the locking function of the pre-assembly protrusion 155c. The second cover support arm 126b can protrude from the first cover body 110 toward the second lighting cover part 151B.

[0452] As a result, when the first cover body 110 is assembled to the second cover body 140, the first cover body 110 can compensate for the second cover body 140, thereby realizing the installation structure of the first cover plate 190a and the second cover plate 190b. Thus, this embodiment can effectively prevent the first cover plate 190a and the second cover plate 190b from being separated while improving the convenience of installing the first cover plate 190a and the second cover plate 190b.

[0453] Since the first cover plate 190a and the second cover plate 190b need to transmit light, the first cover plate 190a and the second cover plate 190b can be made of transparent or translucent materials. In this embodiment, the first cover plate 190a and the second cover plate 190b are made of translucent materials, but can also be made of completely transparent materials such as glass.

[0454] The two surfaces of each of the first cover plate 190a and the second cover plate 190b may also have different surface roughness. With the first cover plate 190a as a reference, the surface roughness of one side of the first cover plate 190a may be greater than the other side. In this embodiment, the surface roughness of the surface of the first cover plate 190a facing the second storage space 41, that is, the surface roughness of one side of the first cover plate 190a is greater than the surface roughness of the surface facing the front of the door 50, 70, that is, the other side of the first cover plate 190a. Thus, the first cover plate 190a guides the diffuse reflection of the light irradiated from the first lighting unit 180a, so that the first lighting unit 180a can evenly irradiate light to a larger area inside the second storage space 41. The second cover plate 190b, like the first cover plate 190a, may have a surface roughness of the surface facing the second storage space 41, that is, the surface roughness of one side of the second cover plate 190b, that is, the surface roughness of the other side of the second cover plate 190b, that is, the surface facing the front of the door 50, 70.

[0455] On the other hand, re-referencing Fig.62 , a plurality of heat dissipation holes 156 may be provided in the second cover body 140. The heat dissipation holes 156 may be formed by penetrating the second cover body 140 in the front-to-back direction. The heat dissipation holes 156 may be formed at a position higher than the center of the second cover body 140 based on the height direction of the second cover body 140. Thus, in the installation space between the first cover body 110 and the second cover body 140, the air with increased temperature can flow to the upper side and then be discharged to the outside through the plurality of heat dissipation holes 156.

[0456] The heat dissipation holes 156 may be formed in the form of long holes. Fig.62As a reference, the plurality of heat dissipation holes 156 may be formed long in the left-right direction. The heat dissipation holes 156 may be formed not only in the sensor cover 142 and the lighting cover 151, but also in the cover body 141 at a position corresponding to the upper portion of the module flow path R. In this embodiment, the heat dissipation holes 156 formed in the sensor cover 142 are larger than the heat dissipation holes 156 formed in the lighting cover 151 or the upper portion of the module flow path R.

[0457] like Fig.62 As shown, the second cover body 140 may be provided with a close-fitting portion 158k, 162. The close-fitting portion 158k, 162 is a portion protruding from the second cover body 140 toward the first cover body 110. Therefore, from the front of the second cover body 140, it can be seen that the close-fitting portion 158k, 162 is in a concave shape. The close-fitting portion 158k, 162 can reduce the interval between the second cover body 140 and the first cover body 110. In this embodiment, the close-fitting portion 158k, 162 is respectively provided on the lighting installation portion 151B and the second connecting body 160. Since the lighting installation portion 151B and the second connecting body 160 are portions protruding from the second cover body 140 toward the lower storage space 41, it is necessary to reduce the interval with the first cover body 110. For this purpose, the close-fitting portion 158k, 162 can be provided.

[0458] In the close contact parts 158k and 162, the close contact part 158k may be provided with the fastening protrusion 158 (see Fig.59 ). In addition, in the close contact parts 158k and 162, the close contact part 162 may be provided with the fastening arm 159 (refer to Fig.59 The close-fitting portions 158k and 162 can make the fastening protrusion 158 and the fastening arm 159 closer to the surface of the first cover body 110.
