In addition, the embodiments can be combined with each other, but must be based on that those skilled in the art can realize it. When the combination of the embodiments is contradictory or cannot be achieved, the combination of the embodiments should not be considered as being within the claimed scope of the present application.
With the development of technology, the air conditioner has gradually become an indispensable home appliance in the daily life of people, and people's requirements on differentiation and multi-function are increasing. Currently, the movable air conditioner is generally provided with a heat exchanger and a volute inside the housing, and a heat exchange air channel communicating with the heat exchanger is formed in the volute. In the related art, the volute is directly screwed and fixed in the housing through screws, which has the defect that the installation is unstable.
In view of the above, the present application provides a movable air conditioner, and FIGS. 1-24 are specific embodiments of the movable air conditioner provided by the present application.
Referring to FIG. 1, FIG. 2 and FIG. 15, the present application provides a movable air conditioner, the movable air conditioner includes a housing 50, a middle partition plate 1 and a volute 2. The middle partition plate 1 is arranged in the housing 50. The volute 2 is arranged in the housing 50. The volute 2 and the middle partition plate 1 are provided with a fixing structure, and the fixing structure is arranged around the volute 2 to fix the volute 2 on the middle partition plate 1.
According to the embodiments provided by the invention, the middle partition plate 1 can limit a downward movement of the volute 2. By arranging the fixing structure around the volute 2, the volute 2 can be restricted to move in a circumferential direction, thus, good fixation of the volute 2 in the housing 50 is achieved, and the installation stability of the volute 2 is improved.
It should be noted that, in this embodiment, the middle partition plate 1 is arranged in a middle part of the housing 50, so as to divide the housing 50 into an indoor side cavity and an outdoor side cavity which are distributed along an up-down direction. The movable air conditioner includes an indoor side heat exchanger 200, an outdoor side heat exchanger (not shown in the figures) and an outdoor heat exchanging air duct (not labeled in the figures). The indoor side heat exchanger 200 is arranged in the indoor side cavity. An indoor side heat exchanging air duct is formed in the volute 2 and includes an air inlet and an air outlet. The orientation of each of the air inlet and the air outlet can be any one in various orientations, but in this embodiment, the air inlet is optionally formed on one side of the volute 2 close to the indoor side heat exchanger 200, and communicates with the indoor side heat exchanger 200, and the air outlet is formed at an upper end of the volute 2. Therefore, a length of the indoor side heat exchanging air duct is prolonged. The outdoor side heat exchanger is arranged in the outdoor side cavity, the outdoor side heat exchanging air duct is communicated with the outdoor side heat exchanger and the indoor side heat exchanging air duct. The specific heat exchange principle of the movable air conditioner using the indoor side heat exchanger 200 and the outdoor side heat exchanger can make reference to the related art, and is not described in detail here.
In addition, the fixing structure is arranged around the volute 2 in this design, that is, the fixing structure is arranged at a periphery of the volute 2 along a circumferential direction of the middle partition plate 1, and the fixing structure can be of a structure arranged along a circumferential direction of the middle partition plate 1 without an interruption. In one embodiment, the fixing structure is specifically shown as an annular convex rib, and the annular convex rib is arranged on the periphery of the volute 2. The annular convex rib and the middle partition plate 1 cooperate to define a mounting groove. An inner size of the annular convex rib is matched with an outer contour size of a corresponding position of the volute 2, so that the mounting groove can just clamp the volute 2 and connect with the volute 2, and the fixing and mounting of the volute 2 are achieved. Of course, the fixing structure can be of a structure arranged along the circumferential direction of the middle partition plate 1 with one or more interruptions. In another embodiment, the fixing structure is specifically shown as a plurality of convex blocks, and the plurality of convex blocks are distributed on the periphery of the volute 2, so that good limiting of the volute 2 can be achieved, and the advantages of being light and saving materials are also achieved.
Further, referring to FIG. 1 to FIG. 3, in this embodiment, the volute 2 includes an air duct plate 21, the air duct plate 21 is formed on one side of the volute 2 away from the indoor side heat exchanger 200, that is, the side of the volute 2 away from the air inlet. The air duct plate 21 is in an arc shape, so that a large space is formed in the volute 2, and the indoor side heat exchanging air duct can be bent, and the heat exchanging effect can be enhanced. The fixing structure includes a supporting base 31 protruded from the middle partition plate 1, the supporting base 31 is provided below the air duct plate 21 and abuts against the air duct plate 21, thereby restricting the movement of the volute 2 in a direction away from the indoor side heat exchanger 200. Similarly, the supporting base 31 can be of a structure arranged along a length direction of the volute 2 without an interruption or with one or more interruptions. When the supporting base 31 is arranged along the length direction of the volute 2 without an interruption, the supporting base 31 can extend along the length direction of the volute 2 to abut against a whole lower end of the volute 2, so as to enlarge an abutment area between the supporting base 31 and the volute 2. Of course, the supporting base 31 can extend along the length direction of the volute 2 to a part of the lower end of the volute 2. At this time, since the air duct plate 21 is in an arc shape, a remaining part of a lower end of the air duct plate 21 is not abutted against the supporting base 31, and is suspended above the middle partition plate 1. Therefore, one or more cushion blocks (not shown in the figures) can be convexly arranged at the remaining section of the middle partition plate 1 to fill space corresponding to the suspended position, so as to ensure the balance and stability of the volute 2 on the middle partition plate 1.
Next, in this embodiment, an upper end of the supporting base 31 is provided with an abutting surface abutting against an outer wall surface of the air duct plate 21. A shape of the abutting surface is matched with a shape of the outer wall surface of the air duct plate 21. Based on the above, the air duct plate 21 in this embodiment is preferably in an arc shape, that is, the outer wall surface of the air duct plate 21 abutting against the abutting surface is in a convex arc surface shape. In this case, the abutting surface can be provided in a concave arc surface shape, and the abutment area between the supporting base 31 and the air duct plate 21 can be increased with the male-female fitting between the convex arc surface and the concave arc surface.
In addition, in this embodiment, the volute 2 further includes a wind deflector bottom plate 22, the wind deflector bottom plate 22 extends from the lower end of the air duct plate 21 to be away from the air duct plate 21. A shape of the wind deflector bottom plate 22 is adapted to a shape of a corresponding part of the middle partition plate 1, for example, when the middle partition plate 1 is in a flat plate shape at this part, the wind deflector bottom plate 22 is in a flat plate shape parallel to or approximately parallel to the middle partition plate 1. The fixing structure further includes a first blocking rib 32 protruded from the middle partition plate 1. The first blocking rib 32 is provided on one side of the wind deflector bottom plate 22 away from the air duct plate 21, and abuts against a side edge of the wind deflector bottom plate 22 away from the air duct plate 21. An extending direction of the first blocking rib 32 is identical to an extending direction of the side edge of the wind deflector bottom plate 22 away from the air duct plate 21, and the first blocking rib 32 may be exactly equal to or slightly higher than the side edge of the wind deflector bottom plate 22 in height. In this embodiment, the first blocking rib 32 is arranged to cooperate with the supporting base 31, so that the volute 2 can be effectively restricted to move close to or away from the indoor side heat exchanger 200.
In order to enlarge the space in the volute 2 to increase an air inlet amount, referring to FIG. 5, in this embodiment, the volute 2 further includes an extension plate 23 arranged at the lower end of the air duct plate 21. The extension plate 23 extends downwards, and the wind deflector bottom plate 22 is arranged at a lower end of the extension plate 23. Further, a plurality of reinforcing ribs 231 can be provided at the extension plate 23. The plurality of reinforcing ribs 231 extend along a width direction of the extension plate 23, and are arranged at intervals along a length direction of the extension plate 23, which helps to enhance the connection strength of the extension plate 23.
In addition, referring to FIG. 3, FIG. 4 and FIG. 6, in this embodiment, the middle partition plate 1 is provided with a water guide groove 11 which is obliquely arranged. The water guide groove 11 is arranged above the outdoor side heat exchanger. The first blocking rib 32 includes two sections distributed on two sides of the water guide groove 11. An air leakage gap is formed between the two sections of the first blocking rib 32, and a water blocking ridge 221 is formed on the wind deflector bottom plate 22 corresponding to the air leakage gap. The water guide groove 11 is provided with a plurality of water falling holes 111 communicated with the indoor side cavity and the outdoor side cavity. The plurality of water falling holes 111 are arranged at intervals along a length direction of the water guide groove 11, the water guide groove 11 is arranged below the volute 2, and is used for converging condensate water generated in the indoor side cavity to be output to the outdoor side cavity. The inclined water guide groove 11 helps to expand an area range of the water guide groove 11 in the length direction of the volute 2, thereby facilitating the rapid drainage. Then, the water blocking ridge 221 correspondingly covers at least part of a notch of the water guide groove 11, so that the condensate water in the water guide groove 11 can be prevented from being reversely splashedinto the volute 2. A length of the water blocking ridge 221 can be set to be equal to a length of the air leakage gap, so that when the volute 2 is installed on the middle partition plate 1, the air leakage gap is exactly matched with the water blocking ridge 221 in a male-female fitting manner to jointly form a watertight water blocking rib. The water blocking rib can not only block the condensate water from entering the volute 2, but also strengthen the limiting effect of the first blocking rib 32 on the volute 2.
In this embodiment, the water blocking ridge 221 includes a wind deflector 222 arranged on the side edge of the wind deflector bottom plate 22, and the wind deflector 222 protrudes downwards from the wind deflector bottom plate 22. That is, the wind deflector 222 protrudes from the wind deflector bottom plate 22 until being substantially flush with the lower end of the wind deflector bottom plate 22. The wind deflector 222 can block wind from entering the lower end of the wind deflector bottom plate 22, while does not affect the condensate water entering the water guide groove 11 from a position under the water blocking ridge 221.
Based on the above, referring to FIG. 2 and FIG. 3, in this embodiment, at least one second blocking rib 12 is further provided on the middle partition plate 1, the at least one second blocking rib 12 is disposed on one side of the first blocking rib 32 facing away from the volute 2, and an extending direction of each second blocking rib 12 may be identical to that of the first blocking rib 32, and each second blocking rib 12 is provided with an opening for the condensate water to flow to the water guide groove 11. Two adjacent second blocking ribs 12 or the first blocking rib 32 and an adjacent second blocking rib form a drainage groove to allow the condensate water to flow through. The drainage groove formed between the first blocking rib 32 and the second blocking rib 12 is taken as an example, the drainage groove is arranged to be gradually inclined downwards in a direction towards the water guide groove 11, so that the condensate water in the drainage groove is conveniently and thoroughly drained into the water guide groove 11. In addition, the opening on the second blocking rib 12 can be arranged corresponding to the water guide groove 11. A flow shunting rib 13 can be convexly arranged between the opening and the air leakage gap, and the flow shunting rib 13 can be used for dispersing the condensate water from the opening to the water guide groove 11, so that the condensate water is dispersed in the water guide groove 11, and not accumulated at a certain water falling hole 111 in the water guide groove 11 to affect the drainage efficiency.
Referring to FIG. 2, FIG. 3 and FIG. 6, in this embodiment, the volute 2 further includes two side plates 24, the two side plates 24 are distributed on two sides of the air duct plate 21, the two sides of the air duct plate 21 refer to two sides of the air duct plate 21 corresponding to the length direction of the volute 2. The two side plates 24, the air duct plate 21, the extension plate 23 and the wind deflector bottom plate 22 cooperate to form the volute 2.
