Detailed implementation manners
[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope protected by the present utility model.
[0035] It should be noted that all the directional indications in the embodiments of the present utility model are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture. If this specific posture changes, the directional indications will also change accordingly.
[0036] In the present utility model, unless otherwise clearly specified and limited, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal connection of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0037] In addition, in the present utility model, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.
[0038] In the air-cooled series refrigerators, the refrigeration evaporator is placed at the back of the air duct panel, and a blower is provided in front of the evaporator. The blower sends cold air out from the air outlet, and after passing through the storage compartment, it becomes hot air and returns to the evaporator through the return air outlet. During the refrigeration process, there is a temperature difference between the inside and outside of the air duct near the return air outlet, and the hot air in the storage compartment will condense into water droplets on the surface of the air duct panel and flow into the refrigerator storage compartment, resulting in frosting and icing of the food, which affects the user experience. Therefore, it is necessary to collect and drain the condensed water.
[0039] In the related art, a water guide groove is provided on the air duct panel to achieve the purpose of draining the condensed water on the surface of the air duct panel. However, the water guide groove is a rib structure and is provided on the surface of the air duct panel, with a complex appearance and a large space occupation. At the same time, when the user places food, it is easy to accidentally touch the water guide groove, resulting in the condensed water in the water guide groove falling and mixing with the food to form frost, reducing the storage quality of the food.
[0040] Moreover, in the related art, the rib structure occupies more than 40% of the air duct panel, resulting in an unclean appearance, and the rib structure will occupy the food storage space inside the refrigerator.
[0041] To solve the above problems to a certain extent, the embodiments of the present application provide an air duct panel and a refrigerator, hiding the diversion structure in the return air grille. Therefore, when a user places food, it is not easy to touch the diversion structure, thereby improving the situation where the user touches the water guide groove, causing the condensed water in the water guide groove to drop and mix with the food to form frost, and improving the storage quality of the food.
[0042] The present application will be described below with reference to the accompanying drawings and specific embodiments:
[0043] Please refer to Figures 1 - 10 , the embodiments of the present application provide an air duct panel 100. The air duct panel 100 provided by the embodiments of the present application can improve the situation where the user touches the water guide groove, causing the condensed water in the water guide groove to drop and mix with the food to form frost, and improve the storage quality of the food.
[0044] Please refer to Figures 2 - 4 , the embodiments of the present application provide an air duct panel 100, which is applied to a refrigerator 10 and includes a panel body 110 and a return air grille 130. The panel body 110 is provided with a return air outlet 111 and a diversion structure 120. The return air grille 130 is connected to the panel body 110, and the return air grille 130 is installed at the return air outlet 111 and blocks the diversion structure 120.
[0045] The liner 200 of the refrigerator 10 is used to provide a storage space for food. The air duct panel 100 is detachably connected to the liner 200 and forms an air duct 300 with a part of the liner 200. The air duct 300 is provided with a refrigeration component, a fan, a drainage device, etc. The panel body 110 is the basic component of the air duct panel 100 in the present application. The panel body 110 can provide an installation basis for the air duct panel 100 and at least some other components in the air duct 300, and can also play the role of protecting the air duct panel 100 and at least some other components in the air duct 300. The return air grille 130 and the fan are both installed on the panel body 110.
[0046] The return air outlet 111 is connected to the air duct 300 and is used for the hot air that has exchanged heat in the liner 200 to flow back into the air duct 300. The return air grille 130 has a plurality of through holes communicating with the return air outlet 111, that is, the hot air enters the return air outlet 111 through the plurality of through holes. The return air grille 130 has the functions of intercepting and collecting the cold in the storage room, increasing the cross-sectional area of the return air outlet 111, reducing the resistance during the air circulation process, and thus improving the refrigeration efficiency of the refrigerator 10, etc. The diversion structure 120 is used to divert the condensed water formed on the panel body 110, so that the condensed water enters the drainage device in the air duct 300 to achieve the collection of the condensed water.
[0047] The return air grille 130 is installed at the return air inlet 111 and blocks the diversion structure 120, that is, the projection of the return air grille 130 on the panel body 110 completely covers the diversion structure 120. In other words, the diversion structure 120 is completely hidden in the return air grille 130 and is not directly exposed on the surface of the panel body 110. Therefore, when the user takes food, it is not easy to accidentally touch the diversion structure 120, so the condensed water in the diversion structure 120 is not easy to drop, reducing the condensed water falling on the food and improving the storage quality of the food.
[0048] The return air grille 130 blocking the diversion structure 120 can also make the appearance of the storage room more concise. At the same time, it can also provide certain protection for the diversion structure 120, reducing the situation where the diversion structure 120 is damaged due to human touch and extending the service life of the diversion structure 120. And because the diversion structure 120 is hidden in the return air grille 130, that is, the diversion structure 120 does not occupy the storage space of the storage room, more storage space can be left to store food.
[0049] In some embodiments, please refer to Figure 6 and Figure 7 , the projection of the return air grille 130 on the panel body 110 is larger than the return air inlet 111.
[0050] That is, the projection of the return air grille 130 on the panel body 110 completely covers and extends beyond the return air inlet 111. A part of the return air grille 130 is used to dock with the return air inlet 111 for hot air circulation, while the part of the return air grille 130 that extends beyond the return air inlet 111 is used to block the diversion structure 120.
[0051] Specifically, both the return air grille 130 and the return air inlet 111 are generally rectangular, and the return air inlet 111 forms an avoidance space 112. The part of the return air grille 130 that extends beyond the return air inlet 111 corresponds to the avoidance space 112. The diversion structure 120 can be located in the avoidance space 112, so that when the return air grille 130 is assembled with the return air inlet 111, it can also block the diversion structure 120, thus eliminating the need to add an additional structure for blocking the diversion structure 120 on the return air grille 130 and making the overall structure of the return air grille 130 simpler.
[0052] In some embodiments, please refer to Figure 4 and Figure 5 , the return air grille 130 protrudes from the panel body 110, and the diversion structure 120 is arranged between the panel body 110 and the return air grille 130.
[0053] Of course, the return air grille 130 protrudes from the side of the panel body 110 facing away from the air duct 300. Since the return air grille 130 protrudes from the panel body 110, that is, there is a certain distance between at least part of the return air grille 130 and the panel body 110, so that the diversion structure 120 can be located between the panel body 110 and the return air grille 130.
[0054] Obviously, the diversion structure 120 has a diversion port 121 for draining the condensed water on the panel body 110. In order to enable all the condensed water on the panel body 110 to enter the diversion port 121 and not leak out through the gap between the return air grille 130 and the panel body 110, resulting in the condensed water flowing onto the food, the diversion structure 120 is also fixedly connected to the return air grille 130, that is, the diversion structure 120 is connected and arranged between the return air grille 130 and the panel body 110. Moreover, the connection between the diversion structure 120 and the return air grille 130 can also make the overall structure of the air duct panel 100 more compact.
[0055] In some embodiments, please refer to Figures 4 - 6 , the diversion structure 120 is located at the top of the return air grille 130.
[0056] The diversion structure 120 is located at the top of the return air grille 130, that is, the diversion structure 120 is located above the return air inlet 111. The condensed water flows downward on the panel body 110 under the action of gravity. Since the return air inlet 111 is a hollow structure, in order to prevent the condensed water from directly flowing into the return air inlet 111 and being unable to enter the drainage device, the diversion structure 120 needs to be located above the return air inlet 111. That is, before the condensed water on the panel body 110 flows to the return air inlet 111, it will be first diverted by the diversion structure 120 into the diversion port 121 for discharge, thereby avoiding the condensed water from directly flowing into the return air inlet 111 to a certain extent.
[0057] Of course, since the diversion structure 120 is located at the top of the return air grille 130, the avoidance space 112 formed by the return air inlet 111 is also located above the return air inlet 111, so that the diversion structure 120 can be arranged in the avoidance space 112.
[0058] In some embodiments, the diversion structure 120 includes two diversion plates 122, and the two diversion plates 122 are arranged at intervals to form the diversion port 121.
[0059] Two deflector plates 122 can be arranged oppositely and are connected to the return air grille 130. Therefore, the air deflector opening 121 is surrounded by the two deflector plates 122, the panel body 110, and the return air grille 130. The deflector plates 122 are used to deflect the condensed water on the panel body 110, so that the condensed water enters the air deflector opening 121 through the deflector plates 122. The air deflector opening 121 is correspondingly arranged with the drainage device in the air duct 300, so that the condensed water flowing into the air deflector opening 121 can enter the drainage device and be collected.
[0060] In some embodiments, both of the two deflector plates 122 are arranged to incline downward in the direction towards the air deflector opening 121.
[0061] The opposite ends of the two deflector plates 122 form the air deflector opening 121. Both of the two deflector plates 122 are inclined, and the opposite ends of the two deflector plates 122 are lower than the opposite ends, presenting an inverted "V" shape as a whole. Since the air deflector opening 121 is located between the two deflector plates 122, in order to divert the condensed water to the air deflector opening 121, the opposite ends of the two deflector plates 122 incline downward, and the condensed water enters the air deflector opening 121 through the deflector plates 122 under the action of gravity.
[0062] In order to enable the condensed water formed in any area on the panel body 110 to enter the diversion structure 120 and ensure the diversion effect, the width of the diversion structure 120 needs to be basically the same as the width of the panel body 110. At the same time, in order to reduce the occupied height of the diversion structure 120 on the panel body 110, thereby reducing the height dimension of the return grille, the included angle formed by the two deflector plates 122 can be an obtuse angle. Specifically, the included angle formed by the two deflector plates 122 is 170°.
[0063] Of course, in other embodiments, the included angle formed by the two deflector plates 122 can also be a right angle or an acute angle, and there is no limitation on this.
[0064] In some embodiments, please refer to Figure 7 , the panel body 110 is further provided with a drainage structure 140. The drainage structure 140 is arranged in the return air inlet 111, and the drainage structure 140 is communicated with the diversion structure 120.
[0065] Since the diversion structure 120 is arranged at the top of the return air grille 130 and has a certain distance from the drainage device in the air duct 300, in order to ensure that the condensed water entering the air deflector opening 121 can be centrally diverted to the drainage device in the air duct 300, the panel body 110 is further provided with a drainage structure 140. The drainage structure 140 is arranged in the return air inlet 111, that is, arranged below the diversion structure 120 and located in the air duct 300. The drainage structure 140 is correspondingly arranged with the drainage device and is communicated with the diversion structure 120. Therefore, the condensed water entering the air deflector opening 121 will converge into the drainage structure 140 and enter the drainage device through the drainage structure 140.
[0066] In some embodiments, refer to Figure 7 and Figure 8 , the drainage structure 140 includes a drainage plate 141 and side plates 142 disposed on both sides of the drainage plate 141. The drainage plate 141 and the two side plates 142 form a drainage groove, and the drainage groove is connected to the diversion structure 120.
[0067] That is, the drainage groove is connected to the diversion port 121. The condensed water flowing out of the diversion port 121 will enter the drainage groove. The drainage plate 141 serves as the bottom wall of the drainage groove, and the condensed water will flow along the drainage plate 141 and finally enter the drainage device in the air duct 300. The drainage groove can centrally divert the condensed water to ensure that all the condensed water can enter the drainage device, improving the collection effect of the condensed water.
[0068] Specifically, an installation groove 134 is provided on one side of the return air grille 130 opposite to the air duct 300. The drainage structure 140 is embedded in the installation groove 134 and is docked with the diversion port 121 to achieve the fixed installation of the drainage structure 140.
[0069] In some embodiments, the drainage plate 141 has a guiding inclined surface 143.
[0070] Since the drainage groove needs to divert the condensed water to the drainage device, a guiding inclined surface 143 is provided on the drainage plate 141 to better divert the condensed water. And the guiding inclined surface 143 is correspondingly arranged with the drainage device. Under the action of gravity, the condensed water can flow along the guiding inclined surface 143 and finally enter the drainage device.
[0071] The drainage plate 141 can be entirely a guiding inclined surface 143, or part of it can be a guiding inclined surface 143, and there is no limitation on this. When part of the drainage plate 141 is a guiding inclined surface 143, the guiding inclined surface 143 is located on the side of the drainage plate 141 away from the diversion port 121, so that the condensed water entering the installation groove 134 can enter the drainage device through the guiding inclined surface 143.
[0072] In some embodiments, the drainage structure 140 further includes a water guiding strip 144. The water guiding strip 144 is disposed at the lower part of the return air grille 130, and the water guiding strip 144 is inclined and connected to the guiding inclined surface 143.
[0073] When the condensed water flows out of the drainage groove, in order to further guide the condensed water so that the condensed water can accurately enter the drainage device, a water guiding strip 144 is also provided at the lower part of the return air grille 130. The water guiding strip 144 is inclined and connected to the guiding inclined surface 143. That is to say, the water guiding strip 144 can be regarded as an extension of the guiding inclined surface 143. That is, after the condensed water flows out of the drainage groove, it flows to the drainage device through the water guiding strip 144.
[0074] The water guide strip 144 has the same inclination angle as the guiding inclined surface 143, and the inclination angle of the water guide strip 144 and the guiding inclined surface 143 can be set accordingly according to the position of the drainage device. Specifically, the included angle between the water guide strip 144 and the guiding inclined surface 143 and the horizontal plane can be 35°.
[0075] In some embodiments, please refer to Figure 9 and Figure 10 , the return air grille 130 includes a connected first return air part 131 and a second return air part 132. The first return air part 131 shields the diversion structure 120, the second return air part 132 is located below the first return air part 131, and the second return air part 132 is inclined relative to the first return air part 131.
[0076] The first return air part 131 and the second return air part 132 form a return air member. The return air member is disposed opposite to the return air inlet 111. The diversion structure 120 is connected and disposed between the panel body 110 and the first return air part 131. The first return air part 131 can be disposed parallel to the panel body 110, so that there is a gap between the first return air part 131 and the panel body 110, which can be used to install the diversion structure 120. The return air grille 130 further includes connecting plates 133 oppositely disposed on both sides of the return air member. The connecting plates 133 are connected to the panel body 110, thereby realizing the installation of the return air grille 130 at the return air inlet 111.
[0077] The return air member and the two connecting plates 133 enclose a chamber. The opening of the chamber faces the air duct 300. The drainage structure 140 is located in the chamber and is installed on the return air member. In order to make the installation of the drainage structure 140 more stable, the drainage plate 141 is connected to both the first return air part 131 and the second return air part 132. Since the guiding inclined surface 143 is provided on the side of the drainage plate 141 away from the diversion port 121, the second return air part 132 is inclined relative to the first return air part 131, and the guiding inclined surface 143 is fitted and installed on the second return air part 132. That is, the inclination angle of the second return air part 132 is the same as that of the guiding inclined surface 143, and the second return air part 132 provides an installation basis for the guiding inclined surface 143, thereby realizing the stable installation of the drainage structure 140.
[0078] Based on the same inventive concept, please refer to Figure 1 and Figure 2 , the embodiment of the present application further provides a refrigerator 10, including a box liner 200 and the above-mentioned air duct panel 100. The air duct panel 100 is disposed in the box liner 200 and forms an air duct 300 with a part of the box liner 200. The return air inlet 111 is communicated with the air duct 300.
[0079] The liner 200 of the refrigerator 10 is used to provide a storage space for food. The air duct panel 100 is detachably connected to the liner 200 and forms an air duct 300 together with a part of the liner 200. A refrigeration component, a fan, a drainage device, etc. are provided in the air duct 300. The refrigeration component is used to refrigerate the air. The fan sends the cold air out from the air outlet, and after passing through the liner 200, it becomes hot air, and then returns to the air duct 300 through the air return port 111 to be refrigerated by the refrigeration component again, forming a cold air circulation. The beneficial effects of the refrigerator 10 provided by the embodiments of the present application are the same as those of the air duct panel 100 described above, and will not be elaborated here.
[0080] In some embodiments, a drainage device is provided in the air duct 300, and the diversion structure 120 can divert the condensed water formed on the panel body 110 to the drainage device provided in the air duct 300.
[0081] The drainage device is used to finally collect the condensed water and discharge the condensed water together. The drainage device is correspondingly arranged with the diversion structure 120, so that the diversion structure 120 can divert the condensed water formed on the panel body 110 into the drainage device. Specifically, the drainage device can adopt an aluminum water receiving tray.
