[0029] The following further describes the present application in detail Figures 1-5 in conjunction with the accompanying drawings.

[0030] The embodiment of the present application discloses a dew condensation prevention visit window system for a visit passageway in a food factory, which is used to facilitate visitors to visit the production workshop through the visit window in the visit passageway, and effectively reduces the probability of dew condensation on the side of the visit window close to the production workshop.

[0031] Embodiment 1: Referring to Figure 1 and Figure 2 , the visit window system is installed based on the heat-insulating wall 3 between the visit passageway 1 and the production workshop 2. The heat-insulating wall 3 has a rectangular space for installing the visit window system, and the length direction of this space is the same as the moving direction of the visitors in the visit passageway 1.

[0032] The visit window system includes a frame 4, three pieces of glass 5 and a hot air device 6.

[0033] The frame 4 is in an overall rectangular frame structure, which is fixedly installed on the heat-insulating wall 3 and is located in the space reserved for the visit window system on the heat-insulating wall 3. In practical applications, other structures are also provided between the frame 4 and the heat-insulating wall 3 to strengthen the connection strength between the frame 4 and the heat-insulating wall 3; in this embodiment, since the structures with the above functions are prior arts in this field, they will not be elaborated here, and only a brief representation is made of them in the drawings.

[0034] The glass 5 is in an overall rectangular sheet structure. The glass 5 is fixedly installed in the space enclosed by the frame 4. The three pieces of glass 5 are equally spaced along the thickness direction of the frame 4 in the space enclosed by the frame 4, and an air cavity 51 is formed between adjacent pieces of glass 5.

[0035] Inside the top of the frame body 4, an air supply chamber 41 and a return air chamber 42 are provided. The air supply chamber 41 and the return air chamber 42 are distributed inside the frame body 4 along the thickness direction of the frame body 4. The bottoms of the air supply chamber 41 and the return air chamber 42 are respectively communicated with the tops of two air cavities 51. In this embodiment, preferably, the shapes of both the air supply chamber 41 and the return air chamber 42 are rectangular parallelepipeds, and the length direction of this rectangular parallelepiped is parallel to the length direction of the frame body 4; and preferably, the air supply chamber 41 is located on the side of the return air chamber 42 close to the viewing passage 1.

[0036] Inside the bottom of the frame body 4, two ventilation chambers 43 are provided. The two ventilation chambers 43 are distributed inside the frame body 4 along the thickness direction of the frame body 4. The tops of the two ventilation chambers 43 are respectively communicated with the bottoms of the two air cavities 51, and the two ventilation chambers 43 are communicated with each other. In this embodiment, preferably, the shape of the ventilation chamber 43 is a rectangular parallelepiped, and the length direction of this rectangular parallelepiped is parallel to the length direction of the frame body 4; and preferably, the shapes of the air supply chamber 41, the return air chamber 42, and the ventilation chamber 43 are the same.

[0037] The hot air device 6 includes a first hot air component 61 and a second hot air component 62. Among them, the first hot air component 61 is used to form hot air inside the viewing window; the second hot air component 62 is used to form hot air outside the viewing window.

[0038] The first hot air component 61 includes a first hot air blower 611. The first hot air blower 611 is fixedly installed inside the top of the frame body 4 and is located in the air supply chamber 41, and can blow hot air into the air cavity 51 through the opening between the air supply chamber 41 and the air cavity 51. In this embodiment, since the first hot air blower 611 with the above functions is a common prior art, it will not be described in detail here, and it is only briefly shown in the drawings.

[0039] The second hot air component 62 is installed on the heat preservation wall 3. It is located on the side of the heat preservation wall 3 close to the production workshop 2, and it includes a second hot air blower 621 and a hot air outlet 622. The second hot air blower 621 is fixedly installed on the heat preservation wall 3 and is located above the frame body 4. The hot air outlet 622 is fixedly installed at the bottom of the second hot air blower 621. One end of the hot air outlet 622 is connected and communicated with the second hot air blower 621, and the other end faces the top of the glass 5 on the side close to the production workshop 2. The second hot air blower 621 can blow hot air towards the glass 5 through the hot air outlet 622 to form a hot air curtain to prevent the humid air in the production workshop 2 from contacting the glass 5. In this embodiment, since the second hot air blower 621 and the hot air outlet 622 with the above functions are both common prior arts, they will not be described in detail here, and they are only briefly shown in the drawings.

[0040] Further, since condensation may occur on the observation window under different circumstances, and the degree of condensation on the observation window will be different when the ambient temperature and humidity difference between the observation passage 1 and the production workshop 2 varies. Therefore, it is preferred that the temperature and speed of the hot air blown by the first hot air blower 611 and the second hot air blower 621 can be adjusted by the staff. In this embodiment, since the first hot air blower 611 and the second hot air blower 621 with the above functions are common existing technologies, no further description will be given here.

[0041] Further, to improve the circulation of hot air inside the observation window, it is preferred that a ventilation opening 44 for connecting the air supply chamber 41 and the air return chamber 42 is provided at the top of the frame body 4 between the air supply chamber 41 and the air return chamber 42, and it is preferred that the air inlet end of the first hot air blower 611 communicates with the ventilation opening 44 and the air outlet end faces the opening between the air supply chamber 41 and the air cavity 51.

[0042] At this time, the hot air blown by the first hot air blower 611 will first enter the corresponding air cavity 51 from the air supply chamber 41, then enter the other air cavity 51 through the two ventilation chambers 43 in sequence, then enter the air return chamber 42 and return to the air supply chamber 41 through the ventilation opening 44.

[0043] Furthermore, to facilitate the maintenance of the first hot air blower 611 by the staff, it is preferred that a maintenance opening 411 is provided on one side of the top of the frame body 4 close to the production workshop 2 and a cover plate 412 for controlling the opening and closing of the maintenance opening 411 is detachably connected.

[0044] The maintenance opening 411 communicates with the air supply chamber 41, allowing the staff to maintain the first hot air blower 611 located inside the air supply chamber 41. The size of the maintenance opening 411 is larger than that of the first hot air blower 611, facilitating the disassembly and assembly of the first hot air blower 611 inside the air supply chamber 41. After the cover plate 412 is connected to the frame body 4, it can fill and seal the maintenance opening 411. After the cover plate 412 is detached from the frame body 4, the maintenance opening 411 will be in a completely open state, facilitating the maintenance of the first hot air blower 611 by the staff or the disassembly and assembly of the first hot air blower 611. In this embodiment, it is preferred that the cover plate 412 is detachably connected to the frame body 4 through a plurality of screws. Since the above detachable connection method is a common existing technology, no further description will be given here and it is omitted in the drawings.

[0045] Further, after the first hot air blower 611 operates for a long time, fine dust will be generated inside the observation window. If the fine dust adheres to the glass 5, it will affect the transparency of the observation window, thereby affecting the observation effect. Therefore, it is preferred that a dust removal plate 45 for adsorbing fine dust is also installed inside the frame body 4.

[0046] The dust removal plate 45 is installed in the return air chamber 42 and can cover the opening between the return air chamber 42 and the air cavity 51. The hot air can pass through the dust removal plate 45 smoothly, and the fine dust mixed in the hot air can be intercepted and adsorbed by the dust removal plate 45.

[0047] On one side of the top of the frame body 4 close to the visiting passage 1, an installation opening 49 communicating with the return air chamber 42 is provided. The dust removal plate 45 is adapted to the installation opening 49, and the dust removal plate 45 can enter and exit the return air chamber 42 through the installation opening 49 to complete disassembly and assembly.

[0048] On one side of the top of the frame body 4 close to the visiting passage 1, a seal 410 for controlling the opening and closing of the installation opening 49 is also detachably connected; after the seal 410 is connected to the frame body 4, it can fill and seal the installation opening 49, and at the same time can position the dust removal plate 45 located in the return air chamber 42; after the seal 410 is detached from the frame body 4, the installation opening 49 will be in a completely open state, which is convenient for the staff to complete the disassembly and assembly of the dust removal plate 45. In this embodiment, it is preferably that the seal 410 is detachably connected to the frame body 4 through a plurality of screws; since the above-mentioned detachable connection method is a common prior art, it will not be elaborated here, and it is omitted in the drawings.

[0049] Further, to facilitate the staff to control the hot air device 6 to operate according to requirements before the visitors visit, that is, to eliminate the dew condensation phenomenon on the viewing window before there are visitors passing through the viewing window in the visiting passage 1, it is preferably that the hot air device 6 is equipped with a control module 7 for controlling its opening and closing.

[0050] The control module 7 can control the opening and closing of the first hot air blower 611 and the second hot air blower 621 respectively, and at the same time can control the temperature and speed of the hot air blown by the first hot air blower 611 and the temperature and speed of the hot air blown by the second hot air blower 621.

[0051] In this embodiment, it is preferably that the control module 7 is a physical switch, which is fixedly installed on the wall on the side of the visiting passage 1 away from the viewing window and close to the entrance of the visiting passage 1, so as to facilitate the staff to use the control module 7 to start the hot air device 6 in advance or when leading the visitors and control the effects of the hot air blown by the first hot air blower 611 and the second hot air blower 621 respectively.

[0052] The implementation principle of an anti-dew condensation viewing window system for the visiting passage 1 of a food factory in an embodiment of the present application is as follows: Before the visitors enter the visiting passage 1, the staff first controls the hot air device 6 to start in advance through the control module 7. The first hot air component 61 will form a circulating hot air flow inside the viewing window, evenly heating the glass 5, and reducing the probability of the glass 5 generating condensation and fogging due to temperature difference; the second hot air component 62 will form a hot air curtain on the side of the viewing window close to the production workshop 2 through the second hot air blower 621 and the hot air outlet 622 to blow the surface of the glass 5 close to the production workshop 2, preventing the humid air in the production workshop 2 from contacting the surface of the glass 5, thereby further reducing the probability of condensation on the surface of the glass 5; after that, when the visitors pass by the viewing window, they can clearly visit the production workshop 2 through the viewing window.

[0053] Embodiment 2: Refer to Figure 3 and Figure 4 , the difference between this embodiment and Embodiment 1 is that a fixing plate 46 and a plurality of movable plates 47 are further installed at the opening between the air supply chamber 41 and the air cavity 51 of the frame body 4.

[0054] Refer to Figure 4 and Figure 5 , both the fixing plate 46 and the movable plates 47 are in the shape of rectangular plates, the length direction thereof is parallel to the length direction of the frame body 4, and the width direction thereof is parallel to the thickness direction of the frame body 4.

[0055] The plurality of movable plates 47 are evenly distributed on the frame body 4 along the length direction of the frame body 4, and the end faces between adjacent movable plates 47 are in contact and abutted against each other; the movable plates 47 are located above the fixing plate 46, and the end faces between the movable plates 47 and the fixing plate 46 are in contact and abutted against each other.

[0056] A plurality of first through holes 461 are formed on the fixing plate 46, and the plurality of first through holes 461 are evenly distributed on the fixing plate 46 along the length direction of the fixing plate 46; a plurality of second through holes 471 are formed on the movable plates 47, and the plurality of second through holes 471 are evenly distributed on the movable plates 47 along the length direction of the movable plates 47, and the plurality of first through holes 461 on the fixing plate 46 correspond to the plurality of second through holes 471 on the plurality of movable plates 47 one by one.

[0057] The movable plate 47 is movably connected to the frame body 4. The moving direction is parallel to its own width direction, and there are limitations during its movement relative to the frame body 4. When the movable plate 47 moves to the extreme position towards the side close to the viewing passage 1, the size of the through-port formed by the first through-port 461 and the corresponding second through-port 471 for hot air to pass through is the smallest at this time; when the movable plate 47 moves to the extreme position away from the viewing passage 1, the size of the through-port formed by the first through-port 461 and the corresponding second through-port 471 for hot air to pass through is the largest at this time. In this embodiment, it is preferably that the first through-port 461 and the corresponding second through-port 471 have the same size, and preferably when the movable plate 47 moves to the extreme position away from the viewing passage 1, the first through-port 461 and the corresponding second through-port 471 are aligned at this time.

[0058] A connection is formed between the movable plate 47 and the frame body 4 through a plurality of elastic members 48. The two ends of the elastic member 48 are respectively fixedly connected to the corresponding movable plate 47 and the frame body 4. The elastic member 48 can drive the movable plate 47 to move to the extreme position towards the side close to the viewing passage 1 and maintain it. And at this time, the hot air enters the air cavity 51 through the through-port formed by the first through-port 461 and the corresponding second through-port 471, which can meet the temperature requirements for preventing the condensation phenomenon of the glass 5 under normal circumstances. In this embodiment, it is preferably that the elastic member 48 is a compression spring; since the compression spring is a common existing technology, it will not be elaborated here, and it is only briefly shown in the drawings.

[0059] Furthermore, to facilitate the visitors to adjust the heating effect of the first hot air assembly 61 on a partial area of the glass 5 according to their needs, it is preferably that adjustment blocks 472 for controlling the movement of the movable plate 47 relative to the frame body 4 are externally connected to the movable plate 47.

[0060] One end of the adjustment block 472 is fixedly connected to the movable plate 47, and the other end bypasses the dust removal plate 45 and then passes through the frame body 4 and is located on the side of the frame body 4 close to the viewing passage 1. The extending direction of the adjustment block 472 is parallel to the thickness direction of the frame body 4, and the adjustment block 472 is in a penetrating fit with the frame body 4, so that the space inside the viewing window remains sealed during the process that the visitors control the corresponding movable plate 47 to move through the adjustment block 472. In this embodiment, it is preferably that the part of the adjustment block 472 passing through the frame body 4 and located between the return air chamber 42 and the air cavity 51 has a hollow structure to facilitate the smooth entry and exit of hot air.

[0061] At this time, the visitors can, according to their viewing needs, press the adjustment block 472 corresponding to their location to drive the corresponding movable plate 47 to move against the acting force of the elastic member 48, so that the part of the viewing window at its location has sufficient permeability to improve the viewing effect of the visitors.

[0062] The implementation principle of the anti-condensation viewing window system for the viewing passage of the food factory in the embodiment of the present application is as follows: When the effect of heating the glass 5 by the first hot air component 61 in the hot air device 6 inside the viewing window is insufficient, the visitor can drive the corresponding movable plate 47 by controlling the operation block, so as to control the rate of the hot air blown into the air cavity 51 at its position in the air supply chamber 41 by the first hot air blower 611, which is convenient for the visitor to adjust the heating effect of the hot air on the glass 5 in a partial area of the air cavity 51, improve the permeability of a partial area of the viewing window, and thus solve the above problem.

[0063] Embodiment 3: Referring to Figure 5 , the difference between this embodiment and Embodiment 1 is that a total of six dust removal plates 45 are installed in the frame body 4, and a plurality of partition plates 413 for guiding the flow of hot air are installed in the frame body 4 corresponding to the six dust removal plates 45, and the ventilation opening 44 between the air supply chamber 41 and the air return chamber 42 and its related designs (such as the air inlet end of the first hot air blower 611) are cancelled.

[0064] Partition plates 413 are installed in the frame body 4 in the air supply chamber 41, the air return chamber 42 and the two ventilation chambers 43. In this embodiment, it is preferably that a total of four partition plates 413 are installed inside the frame body 4.

[0065] Among them, the partition plates 413 located in the air supply chamber 41 and the partition plates 413 located in the air return chamber 42 are both rectangular plate-like structures, the length direction of which is parallel to the length direction of the frame body 4, and the width direction of which is parallel to the width direction of the frame body 4. There is a spacing between one end in the width direction of the partition plate 413 and the inner wall of the top of the air supply chamber 41 or the air return chamber 42, so that the hot air can flow in the opposite direction after bypassing the partition plate 413; the other end in the width direction of the partition plate 413 separates the opening between the air supply chamber 41 and the air cavity 51 or the opening between the air return chamber 42 and the air cavity 51 to form an inlet and an outlet for the hot air to enter and exit, which is convenient for the hot air to flow inside the viewing window.

[0066] The two partition plates 413 located in the two ventilation chambers 43 are both plate-like structures with right-angle bends, and the two partition plates 413 are symmetrically distributed inside the bottom of the frame body 4. One end after the partition plate 413 is bent separates the opening between the ventilation chamber 43 and the air cavity 51 to form an inlet and an outlet for the hot air to enter and exit, which further facilitates the flow of the hot air inside the viewing window; the other end after the partition plate 413 is bent separates the opening between the two ventilation chambers 43 to form an inlet and an outlet for the hot air to enter and exit, which further facilitates the flow of the hot air inside the viewing window.

[0067] Six dust removal plates 45 are respectively installed at the openings between the air supply chamber 41 and the air cavity 51, at the openings between the two ventilation chambers 43 and the corresponding air cavities 51, at both ends of the opening between the two ventilation chambers 43, and at the opening between the air return chamber 42 and the air cavity 51. And the six dust removal plates 45 are all located at the outlet positions formed by being separated by the corresponding partition plates 413 at the corresponding openings, and can leave the fine dust intercepted and filtered by them in the corresponding air supply chamber 41, air return chamber 42 and the two ventilation chambers 43. In this embodiment, it is preferred that the dust removal plate 45 is fixedly connected to the end of the adjacent partition plate 413.

[0068] At this time, both the air inlet end and the air outlet end of the first hot air blower 611 communicate with the air supply chamber 41. After the hot air blown out by it passes through the corresponding dust removal plate 45 under the guidance of the corresponding partition plate 413 and enters the communicated air cavity 51, it will flow through the position of the air cavity 51 close to the production workshop 2 side, and then enter the corresponding ventilation chamber under the guidance of the corresponding partition plate 413, then pass through the corresponding dust removal plate 45 to leave the ventilation chamber and enter another ventilation chamber, and in the other ventilation chamber, it passes through the corresponding dust removal plate 45 under the guidance of the corresponding partition plate 413 and enters another air cavity 51, then enters the air return chamber and changes the flow direction under the guidance of the corresponding partition plate 413, passes through the corresponding dust removal plate 45 and enters the air cavity 51, and then returns to the air supply chamber 41 along the original path to form a loop.

[0069] During the process of the hot air flowing inside the viewing window, the fine dust in the hot air will be adsorbed and filtered and intercepted by the six dust removal plates 45 in sequence, and the fine dust intercepted and filtered will be respectively left in the air supply chamber 41, air return chamber 42 and the two ventilation chambers 43. In this embodiment, it is preferred to cancel the design of the installation opening 49 and the seal 410 on the frame body 4, and instead, four maintenance openings 411 are opened on the frame body 4 corresponding to the air supply chamber 41, air return chamber 42 and the two ventilation chambers 43, and four covers 412 are detachably connected in total, which is convenient for the staff to disassemble and assemble the six dust removal plates 45 and the four partition plates 413, clean the fine dust left in the air supply chamber 41, air return chamber 42 and the two ventilation chambers 43, and when the maintenance openings 411 are closed by the covers 412, the air supply chamber 41, air return chamber 42, the two ventilation chambers 43 and the two air cavities 51 inside the frame body 4 will form a closed space.

[0070] Furthermore, to facilitate the staff to control the hot air effect of the first hot air assembly 61 on the inside of the viewing window, it is preferred that the dust removal plate 45 corresponding to the air supply chamber 41 is slidably connected to the frame body 4, and its sliding direction is parallel to the thickness direction of the frame body 4; and it is preferred that an adjusting rod 414 for controlling the sliding of the dust removal plate 45 is externally connected to the dust removal plate 45.

[0071] During the process of the dust removal plate 45 sliding relative to the frame body 4, the coverage range of the dust removal plate 45 at the through - opening between the air supply chamber 41 and the air cavity 51 changes, and there are an inlet for the hot air to directly enter the air supply chamber 41 and an outlet for the hot air to pass through the dust removal plate 45 and enter the air cavity 51 at this through - opening. After the coverage range of the dust removal plate 45 at the through - opening between the air supply chamber 41 and the air cavity 51 increases, the range for the first hot air blower 611 to blow hot air into the air cavity 51 also increases, thereby improving the heating effect of the first hot air assembly 61 on the glass 5.

[0072] The adjusting rod 414 is in an overall long - strip rod - shaped structure. One end of the adjusting rod 414 is fixedly connected to the corresponding dust removal plate 45, and the other end of the adjusting rod 414 passes through the top of the frame body 4 and is located on the side of the frame body 4 close to the viewing passage 1. The length direction of the adjusting rod 414 is parallel to the thickness direction of the frame body 4, and the adjusting rod 414 is in a through - fit with the frame body 4, so that the space inside the viewing window remains sealed during the process of the staff controlling the corresponding dust removal plate 45 to slide through the adjusting rod 414.

[0073] The implementation principle of an anti - condensation viewing window system for the viewing passage 1 of a food factory in an embodiment of the present application is as follows: During the operation of the first hot air assembly 61, the hot air can form a loop inside the viewing window under the action of the four partition plates 413 and the six dust removal plates 45. At the same time, it can more effectively adsorb and filter the dust mixed in the hot air, facilitating the subsequent removal of the dust inside the viewing window by the staff to ensure the transparency of the viewing window. When the heating effect of the first hot air assembly 61 in the viewing window on the glass 5 is insufficient in the hot air device 6, the staff can control the corresponding dust removal plate 45 to slide by operating the lever, thereby controlling the rate of the hot air blown from the first hot air blower 611 into the air cavity 51 in the air supply chamber 41, and thus solving the above - mentioned problem.

[0074] The above are all the preferred embodiments of the present application. Without limiting the protection scope of the present application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
