Detailed Description
In order to further describe the technical means and effects adopted for achieving the preset aim of the invention, the following detailed description refers to the specific implementation, structure, characteristics and effects according to the application of the invention with reference to the accompanying drawings and preferred embodiments. In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, the particular features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.
As shown in fig. 1 to 3, a chassis 100 according to an embodiment of the present invention includes a chassis body 1 and a clamping portion 2 disposed on the chassis body 1, where the clamping portion 2 is used to be clamped with a caster 3. Wherein, the clamping part 2 is a non-open hole type clamping part. The term "non-through hole type clamping portion" as used herein means that the clamping portion 2 is not provided with a through hole penetrating the chassis 100 in the tray body 1.
In the above technical solution, because the clamping portion 2 on the tray body 1 of the chassis 100 for clamping with the caster 3 is a non-through hole type clamping portion, the condensed water on the tray body 1 cannot leak from the clamping portion 2, and thus the water leakage preventing performance of the chassis 100 can be improved.
Further, the clamping portion 2 can be integrally formed on the tray body 1, so as to improve the connection stability between the clamping portion 2 and the tray body 1.
Further, as shown in fig. 2 and 3, the aforementioned engaging portion 2 may include a locking groove 21 to engage with the caster 3 through the locking groove 21. Preferably, the caster 3 may have an outline matching with the clamping groove 21, so as to be embedded in the clamping groove 21 to realize clamping with the clamping groove 21.
Further, as shown in fig. 2 and 3, the aforementioned engaging portion 2 may include a protruding portion 20 protruding from the tray body 1. The boss 20 includes a catch plate 201 opposite the disc 1. The card 201 and the disk 1 have a gap therebetween so as to form the card slot 21 at the gap. In this example, since the card slot 21 is located above the tray body 1, there is a technical effect of facilitating insertion of the caster 3 into the card slot 21.
Further, as shown in fig. 3, the aforementioned boss 20 may further include a connection plate 202. One end of the connecting plate 202 is connected with one end of the clamping plate 201, and the other end is connected with the tray body 1. The connection plate 202 can form a strong support for the card 201 to form a stable card slot 21 structure.
Further, the connecting plate 202 and the clamping plate 201 may be integrally formed, so as to improve the connection stability of the two.
Further, as shown in fig. 3, the cross-sectional profiles of the connecting plate 202 and the clamping plate 201 are L-shaped, so that the clamping groove structure can be easily formed when the end of the connecting plate 202 facing away from the clamping plate 201 is connected with the tray 1.
Further, in one example, as shown in fig. 3, both the connecting plate 202 and the clamping plate 201 may be in a straight shape to form a single-side closed type clamping groove structure. The meaning of "closed" here is the same as the meaning of "non-open hole" described above, i.e. the formed card slot structure does not have a through hole formed in the tray body 1.
In another example, both the connecting plate 202 and the clamping plate 201 may be L-shaped to form a two-sided closed-type clamping groove structure. In another example, both the aforementioned connection plate 202 and the clamping plate 201 may be U-shaped to form a three-sided closed card slot structure. The specific implementation manner may be selected according to the actual requirement of the user, which is not described herein.
Further, as shown in fig. 2 to 5, the aforementioned convex portion 20 is provided on the bottom surface 11 of the tray body 1. The bottom surface 11 has a first edge 111, which first edge 111 is opposite to the opening of the clamping groove 21. Wherein, the bottom surface 11 is between the first edge 111 and the clamping groove 21 without blocking the blocking object such as ribs, convex hulls or grooves, etc. to facilitate the processing of the clamping groove 21 by the mold.
Further, in the foregoing example in which the boss 20 includes the connection plate 202, the connection plate 202 has a connection portion (not shown) to the disk body 1. As shown in fig. 5, the distance L between the connecting portion and the first edge 111 may be 40mm to 60mm, and preferably L is 50mm, so that the clamping groove 21 may be as close to the outer edge of the tray body 1 as possible, so as to shorten the stroke of the mold slide, reduce the volume of the mold frame, reduce the cost of the mold, and improve the reliability of the movement of the mold slide.
Further, as shown in fig. 1, at least one of the aforementioned fastening portions 2 is disposed at different corners of the chassis 1, so that the center of gravity of the chassis 100 is smoother and more reliable.
Furthermore, the tray 1 may further be provided with a positioning structure for positioning the mounting of the caster 3, so as to improve the mounting accuracy of the caster 3. Preferably, as shown in fig. 1 to 5, the positioning structure may include a positioning rib 5, and the positioning rib 5 is used to position the mounting of the caster 3. Wherein, the structure of the positioning rib 5 is relatively simple and the processing is convenient.
Further, as shown in fig. 1 to 5, the foregoing tray 1 is further provided with a screw column 4 for connecting with the caster 3, specifically, the screw column 4 is provided with a threaded hole, and a screw may pass through the caster 3 and be screwed into the threaded hole, so as to cooperate with the foregoing clamping portion 2 to fix the caster 3 on the tray 1.
Embodiments of the present invention also provide a mobile indoor unit including the chassis 100 in any of the above examples.
In the above embodiments, the movable indoor unit provided by the present invention has the advantage of improving the water leakage preventing performance of the chassis 100 due to the provision of the chassis 100.
Embodiments of the present invention also provide a dehumidifier comprising the chassis 100 of any of the examples described above.
In the above embodiment, the dehumidifier provided by the present invention has the advantage of improving the water leakage preventing performance of the chassis 100 due to the provision of the chassis 100.
The working principle and preferred embodiments of the present invention are described below.
The technical scheme provided by the above can solve the following technical problems: 1. the traditional dehumidifier chassis adopts a pluggable caster device, and water leakage is caused. When the chassis is provided with condensed water, the condensed water can flow out to the lower part of the chassis through the inserting and pulling through holes on the chassis, so that water leakage is caused. 2. The chassis of the traditional dehumidifier adopts an open-type clamping groove castor device, and water leakage is caused. When the condensed water exists on the chassis, the condensed water can flow out to the lower part of the chassis through the open-hole clamping groove, so that water leakage is caused. 3. The chassis of the traditional mobile air conditioner adopts a positioning column and a positioning hole for positioning, the opposite angle is fixed by two screws, and the production efficiency is low.
The technical scheme of the application comprises the following steps: 1. the sealed clamping joint is designed on the water storage chassis 100 and is used for fixing the trundles 3, so that the problem of water leakage of the chassis 100 is solved. 2. The castor 3 can be fixed through the closed joint and a screw fastener, and the installation is simple, and is efficient.
As shown in fig. 1 to 6, the chassis 100 is composed of a water storage area 112, a positioning rib 5, a clamping portion 2, a screw column 4, and the like.
Referring to fig. 6, a water storage area 112 is disposed on the chassis 100, and since the water storage area 112 has condensed water, the chassis 100 cannot be fixed by designing a plug-in through hole or an open hole type slot on the dehumidifier, which inevitably results in that the condensed water of the chassis 100 flows out of the chassis from the hole, resulting in water leakage of the chassis 100 and safety accident. According to the technical scheme, the positioning ribs 5 are arranged on the tray body 1 of the chassis 100 for positioning, meanwhile, the clamping part 2 is designed to be fixed on one side of the castor 3, and the other side of the castor 3 can be fixed with the screw column 4 on the chassis 100 only by using one screw fastener. Realizes the chassis caster fixing device with high production efficiency and no water leakage.
The buckle for fixing the truckle 3 on the existing chassis is limited by the product structure, the die structure of the buckle can only be taken out through the mode that the movable die and the fixed die are in touch, and the problem of water leakage exists because the chassis is inevitably in touch with the hole. The technical scheme of the application fully considers the water leakage defect caused by a simple mold-through demolding mode, integrates the mold structure design principle, innovatively applies the mold slide block action principle, and realizes that four closed clamping structures can be realized only by the mold slide block demolding mode, and the caster fixing device product design considers the mold principle, so that the following points are optimized to realize the closed clamping slide block demolding.
(1) The engaging portion 2 of the caster 3 needs to be designed at four corners (as far as possible to the outer edge) of the chassis 100, and as shown in fig. 5, the distance L between the engaging portion 2 and the outer edge of the chassis 100 needs to be as small as possible, and in a specific application example, L may be 50mm. On one hand, the gravity center of the chassis 100 can be more stable and reliable, on the other hand, the stroke of the die slide block can be shortened, the size of the die carrier is reduced, the cost of the die is reduced, and the reliability of the motion of the die slide block is improved.
(2) As shown in fig. 1 to 5, steps (such as ribs, convex hulls or grooves) affecting the demolding of the slider are not allowed in the slider demolding area of the clamping portion 2.
(3) As shown in fig. 3 and 5, the screw post 4 of the rigid castor 3 is not allowed to fall within the above-mentioned ejector zone 113, so as not to interfere with the ejector of the slide.
In order to realize the closed clamping and fixing mode of the chassis 100, the closed clamping and fixing mode can be changed from one-side closed clamping to two-side closed clamping or three-side closed clamping and fixing.
The structure of the closed clamping fixed castor 3 is not only suitable for a mobile air conditioner, but also suitable for a chassis with a water storage function on other products.
According to the above embodiments, the chassis 100 and the movable indoor unit using the same of the present invention have at least the following advantages:
1. The novel positioning and fixing mode of the casters 3 on the chassis 100 of the mobile air conditioner is simple, the installation procedure is simple, and the production efficiency is high. One side of the trundle 3 can be effectively fixed by designing the positioning rib 5 and the clamping part 2, and the other side of the trundle 3 can be fastened by only one screw.
2. The novel mobile air conditioner chassis 100 adopts the closed clamping fixed castor 3, and the hidden danger of water leakage does not exist. The water storage area 112 of the chassis 100 does not have any through holes or grooves, and there is no problem of water leakage at the mounting position of the casters 3.
What needs to be explained here is: under the condition of no conflict, the technical features related to the examples can be combined with each other according to actual situations by a person skilled in the art so as to achieve corresponding technical effects, and specific details of the combination situations are not described in detail herein.
The above description is only of the preferred embodiments of the present invention, and is not intended to limit the present invention in any way, but any simple modification, equivalent variation and modification made to the above embodiments according to the technical substance of the present invention still fall within the scope of the technical solution of the present invention.
