[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0033] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0034] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0035] The condensed water generated by the air conditioner during the cooling process will drip onto the chassis below the heat exchanger, and then gather in the water tank of the chassis, and finally be discharged through the water pump on the chassis.

[0036] Currently, a filter is usually installed at the water inlet pipe of the water pump in the market to filter impurities such as hair and dust. Since the water flow area of ​​the water inlet pipe is small, the filtration area of ​​the filter is too small, and the filter is easily blocked over time.

[0037] In order to solve the above problems, the present invention proposes a chassis 100 assembly.

[0038] See also Figure 1 and Figure 2 In one embodiment of the present utility model, the chassis 100 assembly includes a chassis 100, a water pump 200 and a filter element 300. The chassis 100 is provided with a water receiving trough 110, and the water receiving trough 110 is separated into a water filter trough 111. The side wall of the water filter trough 111 is provided with a water outlet, and the water filter trough 111 is connected to the water receiving trough 110 through the water outlet; the water suction port of the water pump 200 is connected to the water filter trough 111; the filter element 300 is arranged on the chassis 100 and covers the water outlet.

[0039] The technical solution of the present invention is to divide a water filter trough 111 in the water receiving trough 110 of the chassis 100, and set a water outlet on the side wall of the trough 111, and make the filter element 300 cover the water outlet. It can be understood that compared with the solution in the prior art that places the filter in front of the water inlet pipe of the water pump 200, since the trough wall area of ​​the water filter trough 111 of this solution is larger, there is enough area to set the water outlet, which can effectively increase the water flow area of ​​the water outlet, so that the area of ​​the filter element 300 can be set large enough, which is beneficial to increase the filtration area of ​​the filter element 300 of the water pump 200. Even if a local area of ​​the filter element 300 is blocked, the remaining area of ​​the filter element 300 can continue to withstand a large flow load, which helps to extend the service life of the filter element 300, reduce the replacement frequency, and thus reduce maintenance costs.

[0040] The filter element 300 can filter out dust, hair, and other impurities from the water flowing into the water filter tank 111, thereby reducing the amount of dust, hair, and other impurities that enter the water pump 200 and ensuring the normal operation of the water pump 200. If the outlet of the water pump 200 is connected to the water tank of the air conditioner, the chance of dust, hair, and other impurities entering the internal system of the air conditioner can also be reduced.

[0041] It should be noted that the water receiving tank 110 is used to collect condensed water that falls from the heat exchanger to the chassis 100. In actual use, when the air conditioner is in cooling mode, the heat exchanger is the evaporator, and the temperature of the evaporator is lower than the temperature of the air at the air conditioner's air inlet. Therefore, when air enters the air conditioner casing through the air inlet and exchanges heat with the evaporator, the water vapor in the air will form condensed water on the evaporator. The condensed water can fall to the chassis 100, flow into the chassis, and then collect in the water receiving tank 110.

[0042] During the actual manufacturing process, the bottom plate 100 is punched to form the water receiving groove 110 .

[0043] The water suction port of the water pump 200 can be connected to the water filter tank 111 by the water inlet of the water pump 200 being directly connected to the water filter tank 111, or by the water inlet of the water pump 200 being connected to the water filter tank 111 through a pipe.

[0044] Reference Figure 5 、 Figure 7 and Figure 8Optionally, the filter element 300 is snap-fitted to the chassis 100. This snap-fit ​​connection facilitates installation and removal, enabling tool-free disassembly. No additional materials, such as screws, are required during installation, making the snap-fit ​​connection a cost-effective option. The snap-fit ​​installation process is very simple, typically requiring only a single push motion, without the need for rotational movement or pre-installation positioning. This makes the process quick and simple, improving the efficiency of installation, removal, and replacement of the filter element 300. Of course, the present invention is not limited to this embodiment; in other embodiments, the filter element 300 may also be screw-fitted to the chassis 100.

[0045] Furthermore, slots 111a are provided on the opposite side edges of the water outlet, and the edges of the filter element 300 are inserted into the slots 111a; it can be understood that the slots 111a can limit the lateral displacement of the filter element 300, and the installation method of the slots 111a is simple. It is only necessary to push the filter element 300 into the slots 111a, and the filter element 300 can be inserted into the fixed position along the extension direction of the slots 111a, thereby achieving fixation. This installation method is simple and is conducive to improving installation efficiency.

[0046] In this embodiment, the length of the slot 111a extends in the height direction of the water filter trough 111. This prevents interference between the filter element 300 and the wall of the water receiving trough 110 when the filter element 300 is installed. Of course, the present invention is not limited to this. In other embodiments, the length of the slot 111a may also extend along the length of the side wall of the water filter trough 111.

[0047] The insertion end of the slot 111a is flared, which makes it easier for the user to align the filter element 300 with the slot 111a when installing the filter element 300, thereby improving installation efficiency. Of course, the present invention is not limited to this. In other embodiments, the insertion end of the slot 111a may not be flared.

[0048] Furthermore, in this embodiment, the chassis 100 is further provided with a snap-fit ​​portion 120. One of the snap-fit ​​portion 120 and the filter element 300 is provided with a snap-fit ​​groove 121, and the other is provided with a snap-fit ​​protrusion 310 that cooperates with the snap-fit ​​groove 121. It is understood that the filter element 300 slides along the slot 111a. When the snap-fit ​​protrusion 310 or the snap-fit ​​groove 121 on the filter element 300 slides to the position of the snap-fit ​​groove 121 or the snap-fit ​​protrusion 310 on the snap-fit ​​portion 120, the snap-fit ​​protrusion 310 snaps into the snap-fit ​​groove 121, thereby securing the filter element 300. Of course, the present invention is not limited to this. In other embodiments, the edge of the filter element 300 may also be interference-fitted into the slot 111a without providing a snap-fit ​​protrusion.

[0049] It should be noted that the filter element 300 and / or the engaging portion 120 have a certain amount of elastic deformation, so that when the engaging protrusion 310 engages into the engaging groove 121 or the engaging protrusion 310 disengages from the engaging groove 121, the filter element 300 and / or the engaging portion 120 undergo elastic deformation, thereby making the installation and disassembly of the filter element 300 more labor-saving.

[0050] In this embodiment, the engaging groove 121 is provided on the engaging portion 120, and the engaging protrusion 310 is provided on the filter element 300. In other embodiments, the engaging groove 121 may also be provided on the filter element 300, and the engaging protrusion 310 may be provided on the engaging portion 120.

[0051] Furthermore, two latching protrusions 310 are provided on each side of the filter element 300. The two latching protrusions 310 on the same side are located on opposite sides of the filter element 300. It is understood that the latching protrusions 310 on each side of the filter element 300 allow for installation of the filter element 300 without having to determine which side the latching protrusions 310 are facing toward the engaging portion 120. This eliminates the need to determine which direction the latching protrusions 310 are facing, thereby improving installation efficiency. Furthermore, the two latching protrusions 310 on the same side are located on opposite sides of the filter element 300. This allows for insertion into the slot 111a without having to determine which side the latching protrusions 310 are facing, thereby eliminating the need to determine which direction the latching protrusions 310 are facing, thereby improving installation efficiency.

[0052] In this embodiment, the water outlet is provided in the form of a notch that passes through the side wall of the water filter trough 111. This is beneficial for increasing the water flow area of ​​the water outlet and the filtering area of ​​the filter element 300. In this way, even if a local area of ​​the filter element 300 is clogged, the remaining area of ​​the filter element 300 can continue to withstand a larger flow load, which helps to extend the service life of the filter element 300, reduce the replacement frequency, and thus reduce maintenance costs.

[0053] Furthermore, the chassis 100 is also provided with a baffle 130, the two ends of which are respectively connected to the groove walls of the two slots 111a, and the baffle 130 is in contact with the side of the filter element 300 away from the water filter trough 111. It can be understood that the setting of the baffle 130 can block the gap between the filter element 300 and the surface of the chassis 100, thereby reducing the probability of impurities such as hair and dust entering the water filter trough 111 through the gap, thereby improving the cleanliness of the filtration of the filter element 300. Secondly, since the density of impurities such as dust is greater than that of water, impurities with higher density will settle at the bottom of the water receiving trough 110. The baffle 130 can prevent impurities with larger mass from blocking the filter holes of the filter element 300, and can better filter some fine impurities, which is beneficial to improving the service life of the filter element 300 and reducing the replacement frequency of the filter element 300.

[0054] The filter element 300 is configured as a filter mesh, but the present invention is not limited thereto. In other embodiments, the filter element 300 may also be configured as a filter membrane.

[0055] Reference Figure 3 、 Figure 4 and Figure 6 Furthermore, a limiting rib is provided on the inner side surface of the chassis 100 corresponding to the filter element 300 , and the limiting rib abuts against the inner side surface of the filter element 300 , thereby improving the installation stability of the filter element 300 .

[0056] In this embodiment, the limiting rib is configured as two spaced-apart limiting segments, which facilitates the demoulding of the chassis 100. Of course, the present invention is not limited thereto, and in other embodiments, the limiting rib may also be a continuous limiting plate, with both ends of the limiting plate connected to the two slots 111a.

[0057] Optionally, a reinforcement column 111b is provided on the wall of the water filter trough 111. A space 111c is formed between the reinforcement column 111b and the slot 111a. An anti-error rib 111d is provided on the bottom of the water filter trough 111 corresponding to the space 111c. Specifically, in order to increase the strength of the side wall of the water filter trough 111, a reinforcement column 111b is provided on the side wall of the water filter trough 111. The reinforcement column 111b, which is close to the slot 111a and spaced apart from the side wall of the slot 111a, is an easy-to-error reinforcement column. An interval space 111c is formed between the error-prone reinforcement column and the side wall of the slot 111a. The operator may mistake the interval space 111c for the slot 111a, which may lead to incorrect installation of the filter element 300. This solution provides misplacement ribs corresponding to the interval space 111c to avoid user installation errors. If the operator does not find the installation error, the installation stability of the filter element 300 will be reduced, affecting the filtering effect of the filter element 300. If the operator finds it, the operator needs to disassemble and reinstall it, which affects the installation efficiency.

[0058] The extending direction of the anti-misalignment rib 111d intersects with the extending direction of the water outlet, and the anti-misalignment rib 111d is arranged close to the water outlet.

[0059] Furthermore, the anti-misalignment ribs 111d are connected to the limiting ribs, which can increase the strength of the limiting ribs and the anti-misalignment ribs 111d.

[0060] In this embodiment, a plurality of anti-misalignment ribs 111d are provided at intervals. Of course, the present invention is not limited thereto. In other embodiments, only one anti-misalignment rib 111d may be provided. The specific number of the anti-misalignment ribs 111d is not limited herein.

[0061] Specifically, in this embodiment, two anti-misalignment ribs 111d are provided.

[0062] Furthermore, the water filter trough 111 has an opposite side trough wall opposite to the water outlet, and an adjacent side trough wall adjacent to the trough wall with the water outlet, and the anti-error rib 111d is spaced apart from the opposite side trough wall, so as to avoid water flow being retained in the retention trough formed between the anti-error rib 111d and the adjacent side trough wall, or in the retention trough formed by two adjacent anti-error ribs 111d.

[0063] Optionally, the water filter 111 includes a connected water flow section 111e and an installation section 111f, the water pump 200 is installed in the installation section 111f, and the water outlet is provided in the water flow section 111e. It can be understood that this solution divides the water filter 111 into an installation section 111f for installing the water pump 200 and a water flow section 111e for providing the water outlet. In this way, the water outlet is not limited to the size of the installation section 111f for providing the water pump 200. Through the relative position relationship between the water pump 200 and the filter element 300, the water outlet can be designed to be larger, thereby increasing the filtering area of ​​the filter element 300 and not easily causing blockage of the filter element 300.

[0064] The water inlet of the water pump 200 is located at the bottom of the water pump 200. Placing the water pump 200 at the mounting section 111f allows the water pump 200 to directly draw water from the water filter tank 111, thereby saving on the need for diversion piping and reducing costs. Of course, the present invention is not limited to this. In other embodiments, the water pump 200 may also be installed outside the water filter tank 111 and connected to the water filter tank 111 via a conduit.

[0065] In other embodiments, the water filter tank 111 may also be provided only corresponding to the water pump 200 , and the side walls of the water filter tank 111 are all provided with water inlets, and the filter element 300 covers all the water inlets, which can also increase the filtering area of ​​the filter element 300 .

[0066] Optionally, a limiting protrusion 140 is provided at the bottom of the groove of the installation section 111f corresponding to the water pump 200, and the limiting protrusion 140 abuts against the outer peripheral surface of the water pump 200, thereby reducing the vibration of the water pump 200, improving the installation stability of the water pump 200, and reducing the vibration noise of the water pump 200.

[0067] It should be noted that the size of the installation section 111f is compatible with the size of the water pump 200, so that the water pump 200 can be limited by the groove wall of the installation section 111f, which can reduce the vibration of the water pump 200, improve the installation stability of the water pump 200, and reduce the vibration noise of the water pump 200.

[0068] Specifically, the limiting protrusion 140 is provided on a side of the installation section 111f close to the water flow section 111e.

[0069] The limiting protrusion 140 includes a connected limiting rib and a reinforcing rib. The extending direction of the limiting rib intersects the extending direction of the reinforcing rib. The limiting rib abuts the outer circumference of the water pump 200, and the reinforcing rib is connected to the side of the limiting rib facing away from the water pump. This can increase the strength of the limiting protrusion 140. Of course, the present invention is not limited to this. In other embodiments, the limiting protrusion 140 can also include only the limiting rib abutting the outer circumference of the water pump 200. In this case, the strength of the limiting rib can be improved by the rigidity and thickness of the material.

[0070] Furthermore, the width of the installation section 111f is smaller than the width of the water flow section 111e. In this way, the water pump 200 can be limited by the groove wall of the installation section 111f, and the water flow outlet can be designed to be larger, thereby increasing the filtering area of ​​the filter element 300 and not easily causing clogging of the filter element 300.

[0071] Furthermore, the water flow section 111e has a water flow channel wall 111g parallel to the arrangement direction of the water flow section 111e and the installation section 111f, and the water outlet is arranged on the water flow channel wall 111g, so that the filter element 300 can be designed to be larger, thereby increasing the filtering area of ​​the filter element 300 and not easily causing clogging of the filter element 300.

[0072] Of course, the present invention is not limited thereto. In the second embodiment, the water outlet may also be provided on the side wall of the tank opposite to the water outlet section 111 e and the water pump 200 .

[0073] In the third embodiment, the filter element 300 may also be directly used to separate the water filter tank 111 .

[0074] In the fourth embodiment, the mounting section 111f has a connecting groove wall connected to the water channel wall 111g, and the water outlet is provided on the water channel wall 111g and the connecting groove wall.

[0075] The present utility model also proposes an air conditioner, which includes a chassis assembly. The specific structure of the chassis assembly refers to the above-mentioned embodiment. Since this air conditioner adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0076] Optionally, the air conditioner includes an indoor unit and an outdoor unit, and the chassis assembly is provided on the indoor unit; the indoor unit and the outdoor unit are connected via a refrigerant hose assembly, and the refrigerant hose assembly is pre-filled with refrigerant; it can be understood that the air conditioner is a split-type air conditioner that is convenient for users to implement personal installation. It uses a refrigerant hose assembly to connect the indoor heat exchanger of the air conditioner indoor unit and the outdoor heat exchanger of the air conditioner outdoor unit, and refrigerant is injected into the refrigerant circuit before the equipment leaves the factory. In this way, when the user installs the equipment by themselves, they only need to fix the air conditioner indoor unit and the air conditioner outdoor unit separately, without the need to assemble the refrigerant pipe and add the refrigerant, thereby reducing the difficulty of installation and enabling personal installation by the user. However, the present design is not limited to this. In other embodiments, the air conditioner of the utility model can also be an ordinary split-type air conditioner.

[0077] Among them, the refrigerant hose assembly can be a flexible refrigerant tube and a sleeve for sleeveing ​​the flexible refrigerant tube, or it can include any two of the refrigerant tube, the drain pipe and the power wire, and a sleeve for sleeveing ​​the two at the same time, or it can include the refrigerant tube, the drain pipe and the power wire, and a sleeve for sleeveing ​​the three at the same time, to facilitate connection.

[0078] Furthermore, the compressor of the air conditioner is arranged in the indoor unit, which can reduce the weight of the outdoor unit and facilitate the installation of the outdoor unit.

[0079] Optionally, the air conditioner is provided with a noise reduction structure corresponding to the compressor, thereby reducing the noise of the compressor installed in the indoor unit.

[0080] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention.
