[0027] The housing assembly 100 for indoor unit 1000 based on the embodiment of this application is described below with reference to Figs. 1-5.

[0028] As shown in Figs 1-5, the housing assembly 100, based on the embodiment of this application includes face frame 1 and two end covers 2.

[0029] Specifically, front air outlet 111 is mounted on the face frame 1. Two end covers 2 are located in the left and right of the face frame 1 respectively. A part of at least one end cover 2 lies in front of the front surface of the face frame 1, and forms an auxiliary air passage with the face frame 1. The side air outlet 21, connecting the auxiliary air passage a, is mounted on at least one end cover 2. In other words, the wind produced by the indoor unit 1000 can be supplied from the front air outlet 111, or the side air outlet 21 after passing through the auxiliary air passage a, consequently increasing the supply scope of air of the housing assembly 100.

[0030] For the housing assembly 100 based on the embodiment of this application, a part of one end cover 2 lies in front of the front surface of the face frame 1, and forms an auxiliary air passage a with the face frame 1. In this case, the wind produced by the indoor unit 1000 can flow toward the side air outlet 21 along the auxiliary air passage a, and is finally supplied toward the left or right of housing assembly 100. As well, parts of two end covers 2 lie in front of the front surface of the face frame 1, and form auxiliary air passage a with the face frame 1. In this case, the wind produced by the indoor unit 1000 can flow toward two side air outlets 21 along two auxiliary air passages a, and is finally supplied toward the left and right of housing assembly 100.

[0031] The part of the inner side wall of each auxiliary air passage a, which is limited by the face frame 1, forms the guide wall 112. It directs the air from the front air outlet 111 to the side air outlet 21. It is understandable that an air deflector is mounted on the front air outlet 111 of the indoor unit 1000. If the air deflector is open, the wind produced by the indoor unit 1000 is mainly supplied from the front air outlet 111, and seldom through the side air outlet 21 after passing through the auxiliary air passage a. If the air deflector is closed, the wind produced by the indoor unit 1000 flows to the front air outlet 111, and then largely passes along the auxiliary air passage a to the side air outlet 21 (one-way arrow indicates the airflow direction in the Fig. 5).

[0032] It is known that the guide wall 112 can deflect wind. So the guide wall 112 can increase the volume of air flowing to the side air outlet 21 to some extent, thus resulting in the rise in air output of the side air outlet 21. In this case, the air supply efficiency of the side air outlet 21 of the housing assembly 100 is enhanced.

[0033] For the housing assembly 100 for indoor unit 1000 based on the embodiment of this application, a part of at least one end cover 2 lies in front of the front surface of the face frame 1, and forms an auxiliary air passage a with the face frame 1. In addition, the part of the inner side wall of the auxiliary air passage a, which is limited by the face frame 1, forms the guide wall 112. It directs the air from the front air outlet 111 to the side air outlet 21. In this case, the air output of the side air outlet 21 and air supply efficiency of the housing assembly 100 are enhanced.

[0034] In some embodiments of this application, parts of two end covers 2 lie in front of the front surface of the face frame 1, and form an auxiliary air passage a respectively with the face frame 1.

[0035] In this case, the wind produced by the indoor unit 1000 can flow toward two side air outlets 21 along two auxiliary air passages a, and is finally supplied toward the left and right of housing assembly 100. The side air outlet 21, connecting the auxiliary air passage a, is mounted on each end cover 2. The part of the inner side wall of each auxiliary air passage a, which is limited by the face frame 1, forms the guide wall 112. In this case, indoor unit 1000 can supply wind left and right. It ensures the air supply efficiency of the housing assembly 100. Moreover, it enhances the structural strength of the end cover 2, as well as the overall strength of the housing assembly 100.

[0036] Further, face frame 1 includes front frame 11 and two side frames 12.

[0037] Specifically, front air outlet 111 is mounted on the front frame 11. Two side frames 12 are located in the left and right of the front frame 11 respectively, and extend backward. There are guide walls 112 on the front surface of front frame 11 on left and right ends of the front air outlet 111. Therefore, the parts of two end covers 2 in front of the front frame 11 form the auxiliary air passage a respectively with the front frame 11.

[0038] The guide wall 112 extends obliquely backward in a direction away from the front air outlet 111. Each guide wall 112 extends to the corresponding side frame 12. Two end covers 2 match two side frames 12 and are located on the side of corresponding side frame 12 away from the front frame 11. There is front extension part 22 on each end cover 2, which is located in front of the corresponding guide wall 112, and forms the auxiliary air passage a with the guide wall 112. In other words, front extension part 22 forms auxiliary air passage a with the front frame 11. The guide wall 112 can further improve the performance of wind deflection, ensure that the wind flows to the side air outlet 21, and consequently assures the air supply efficiency of the housing assembly 100.

[0039] Specifically, the end of the guide wall 112 adjacent to front air outlet 111 extends to the side wall of the front air outlet 111. It ensures the performance of wind deflection of the auxiliary air passage a. In addition, if the air deflector is closed, the wind from the front air outlet 111 can pass through the auxiliary air passage a, avoiding the interference of front frame 11 to the airflow.

[0040] Specifically, guide grooves 113 are located on upper and lower sides of each guide wall 112 respectively. Each guide groove 113 extends left and right. The end of each guide groove 113 far away from the front air outlet 111 is open. On each front extension part 22, the guide protrusion 221 matches the guide groove 113. Therefore, if the guide protrusion 221 gradually extends into guide groove 113 along the open end of the guide groove 113, it can match the guide groove 113. In this case, the assembly of the front extension part 22 and face frame 1 can be complete. Moreover, it makes assembly simple and reliable, and disassembly convenient. In this case, the assembly of the front extension part 22 and face frame 1 can be complete. Moreover, it makes assembly simple and reliable, and disassembly convenient.

[0041] Optionally, guide groove 113 is located on upper or lower side of each guide wall 112. In other words, guide groove 113 is located on one side of each guide wall 112. It ensures the assembly of the front extension part 22 and frame 1, simple structure of housing assembly 100, and lower production cost of housing assembly 100.

[0042] Further, there is guide bevel 113a on the inner bottom wall on one end of at least one guide groove 113. The guide bevel 113a inclines upward and extends backward in a direction away from the front air outlet 111. Therefore, during the assembly of the face frame 1 and end cover 2, the guide bevel 113a serves as the guide for the assembly of the guide protrusion 221 and guide groove 113. It decreases the difficulties in the assembly of face frame 1 and end cover 2, enhances assembly efficiency, and facilitates the disassembly of end cover 2.

[0043] Preferably, there is guide bevel 113a on the inner bottom wall of each guide groove 113 adjacent to the side frame 12. It can further enhance the assembly efficiency of face frame 1 and end cover 2, and facilitate the disassembly.

[0044] In some embodiments of this application, the guide wall 112 is a plane or an arc. It can assure the performance of wind deflection of the guide wall 112, and simple structure of the guide wall 112.

[0045] In some embodiments of this application, either the face frame 1 or end cover 2 is provided with the hook 3, while the other is configured with the snapping groove 4. In other words, when the face frame 1 is provided with the hook 3, the end cover 2 is configured with the snapping groove 4. When the end cover 2 is provided with the hook 3, the face frame 1 is configured with the snapping groove 4. Through the matching of the hook 3 and snapping groove 4, the face frame 1 and end cover 2 can be assembled. Without using other parts (such as bolt and screw), the face frame 1 and end cover 2 can be connected and fixed. In this way, it makes assembly simple and reliable, enhances assembly efficiency of the end cover 2, simplifies the installation of the housing assembly 100, and facilitates the maintenance and disassembly.

[0046] Further, there are multiple hooks 3 and snapping grooves 4, and the grooves 4 match the hooks 3. It can improve the connection of the face frame 1 and end cover 2, making them fit better. In addition, it assures the reliability and stability of the assembly of the face frame 1 and end cover 2, enhances the reliability and stability of the housing assembly 100, and avoids shake between the face frame 1 and end cover 2 during the operation of indoor unit 1000. Consequently, it reduces the noise during the operation of indoor unit 1000, and brings users comfortable experience.

[0047] Specifically, the face frame 1 and each end cover 2 are both provided with the hook 3 and snapping groove 4. There are multiple hooks 3 and snapping grooves 4, and the grooves 4 match the hooks 3. It facilitates the assembly of the face frame 1 and end cover 2, making it more flexible.

[0048] The housing assembly 100 also includes air outlet grille 5, which is located at the side air outlet 21. In this case, external impurities such as dust can be prevented from entering the interior of the housing assembly 100 through the side air outlet 21, which may influence the normal operation of the indoor unit 1000. Consequently, the cleaning frequency of the indoor unit 1000 can be reduced. Moreover, the air outlet grille 5 can also be used for the wind deflection.

[0049] Further, air outlet grille 5 includes multiple sub-grilles 51, the neighboring two sub-grilles 51 are spaced, at least partially. It can ensure the airflow from the side air outlet 21, and the reliability of the housing assembly 100.

[0050] Specifically, the ends of multiple sub-grilles 51 are connected. It can ensure the airflow from the side air outlet 21, and the simple structure of the air outlet grille 5.

[0051] Optionally, air outlet grille 5 is an all-in-one component. It can improve the production efficiency of housing assembly 100 and simplify the installation of the housing assembly 100.

[0052] Optionally, each sub-grille 51 is in "S" shape. It improves the appearance of the housing assembly 100.
