Abstract
Description
Technical Field
[0001] This invention relates to the field of air conditioning equipment technology, and more specifically, to a chassis assembly and an air conditioner having the same. Background Technology
[0002] Compared to split-type air conditioners, window air conditioners are widely accepted by the market due to their advantages such as small size, low price, convenient and quick installation, and low installation costs.
[0003] In existing window air conditioner structures, a drain hole is installed on the outdoor side to facilitate heating operation. When the outdoor heat exchanger frosts due to the air temperature being lower than the exchanger's, a defrosting mode is activated to melt the frost into water. This water is then drained to the outside of the unit through the drain hole located around the exchanger, preventing water accumulation and freezing that could cause the fan blades to freeze and malfunction. However, this solution has a drawback: in low ambient temperatures, such as -20°C, the defrosting water can easily freeze around the outdoor heat exchanger and accumulate. Furthermore, this solution requires the installation of water pipes, and the building or apartment must have a drainage system connected to it. Therefore, this existing solution is not suitable for locations such as buildings or apartments without drainage pipes.
[0004] Current split-type air conditioner technology uses a chassis with an outdoor heat exchanger, drainage holes, and electric heating to prevent defrost water from condensing in low-temperature environments and to allow it to drain quickly through the drainage holes. Typically, multiple drainage holes are installed at the bottom of the heat exchanger to facilitate rapid drainage and prevent water accumulation. However, this design results in condensate dripping directly onto the outside of the unit through the drainage holes, easily leading to customer complaints about dripping and leaks. Summary of the Invention
[0005] The main objective of this invention is to provide a chassis assembly and an air conditioner having the same, in order to solve the problem that window air conditioners require a building drainage pipe for installation in the prior art.
[0006] To achieve the above objectives, according to one aspect of the present invention, a chassis assembly is provided, comprising: a chassis including a water collection area and a water pumping area, the water pumping area being connected to the water collection area, the water collection area being used to collect liquid water generated during the defrosting process of the heat exchanger, and the water pumping area being used to collect liquid water from the water collection area; and a water pump assembly connected to the chassis, the water pump assembly having an inlet end and an outlet end, the inlet end being connected to the water pumping area to discharge liquid water in the water pumping area to the outside of the chassis through the outlet end.
[0007] Furthermore, the chassis has adjacent first and second sides, a water collection area extends along the first and second sides, a pumping area is formed in the middle of the water collection area, and the bottom of the pumping area is lower than that of the water collection area.
[0008] Furthermore, a baffle plate is provided on the side of the water collection area away from the first side, and a heat exchanger is provided on the side of the baffle plate closer to the first side. The baffle plate and the heat exchanger are provided with a gap, and the first end of the baffle plate extends along the length direction of the first side, and the second end of the baffle plate extends along the length direction of the second side. At least part of the baffle plate is located above the water collection area, and the water pump assembly is connected to the baffle plate.
[0009] Furthermore, the second end of the wind deflector is provided with two mounting sections, both of which extend along the length of the second side. One of the two mounting sections is located close to the second side, while the other mounting section is located away from the second side. The water pump assembly is connected to the two mounting sections.
[0010] Furthermore, the chassis assembly includes an electric heater, at least a portion of which is disposed within the water collection area and extends along the length of the water collection area.
[0011] Furthermore, the chassis is provided with multiple support bosses, at least one of which is protruding within the water collection area and is used to support the heat exchanger.
[0012] Furthermore, the gap is 'a', where 3mm ≤ a ≤ 8mm.
[0013] Furthermore, the pump assembly also includes: a pump bracket connected to two mounting sections; a pump having an inlet end and an outlet end, the inlet end being connected to the pump bracket; a water pipe detachably connected to the outlet end; and a pump cover positioned on top of the pump.
[0014] Furthermore, the two mounting sections are arranged to form an installation position with an opening on one side, and the inlet end is located between the two mounting sections.
[0015] Furthermore, the pump bracket is equipped with a grille, which is arranged along the circumferential direction of the inlet end.
[0016] According to another aspect of the present invention, an air conditioner is provided, including a chassis assembly, wherein the chassis assembly is the chassis assembly described above.
[0017] Applying the technical solution of this invention, the liquid water generated during the defrosting process of the outdoor heat exchanger is collected in the water collection area of the chassis, and then collected in the water pumping area. The inlet end of the water pump assembly is connected to the water pumping area, thereby drawing liquid water from the water pumping area through the inlet end of the water pump assembly, and then discharging the liquid water from the water pumping area to the outside of the chassis through the outlet end of the water pump assembly, ultimately achieving low-temperature operation of the air conditioner. This solution eliminates the need to install additional drainage pipes in places without drainage pipes, such as houses or apartments, meeting the installation requirements of air conditioners in such places. It solves the problem of requiring drainage pipes for window air conditioner installation in the prior art, and avoids problems such as dripping and leakage caused by liquid water generated during the defrosting process of the heat exchanger falling directly to the outside of the unit through the drain hole.

[0037] Combination Figures 1 to 8 As shown, according to a specific embodiment of this application, a chassis assembly is provided.
[0038] Specifically, the chassis assembly includes a chassis 10 and a water pump assembly 50. The chassis 10 includes a water collection area 11 and a water pumping area 12. The water pumping area 12 is connected to the water collection area 11. The water collection area 11 is used to collect liquid water generated during the defrosting process of the heat exchanger 30, and the water pumping area 12 is used to collect liquid water from the water collection area 11. The water pump assembly 50 is connected to the chassis 10 and has an inlet end 511 and an outlet end 512. The inlet end 511 is connected to the water pumping area 12 to discharge liquid water in the water pumping area 12 to the outside of the chassis 10 through the outlet end 512.
[0039] Applying the technical solution of this embodiment, the liquid water generated during the defrosting process of the outdoor heat exchanger 30 is collected through the water collection area 11 of the chassis 10, and then collected through the water pumping area 12. The inlet end 511 of the water pump assembly 50 is connected to the water pumping area 12, thereby drawing liquid water from the water pumping area 12 through the inlet end 511 of the water pump assembly 50, and then discharging the liquid water from the water pumping area 12 to the outside of the chassis 10 through the outlet end 512 of the water pump assembly 50, ultimately achieving low-temperature operation of the air conditioner. This solution eliminates the need to install additional drainage pipes in places without drainage pipes, such as houses or apartments, meeting the installation requirements of air conditioners in places without drainage pipes. It solves the problem that window air conditioners require drainage pipes in the existing technology, and avoids problems such as dripping and leakage caused by liquid water generated during the defrosting process of the heat exchanger 30 falling directly to the outside of the unit through the drain hole.
[0040] The chassis 10 has adjacent first and second sides. A water collection area 11 extends along the first and second sides. A water pumping area 12 is formed in the middle of the water collection area 11, and the bottom of the water pumping area 12 is lower than that of the water collection area 11. This arrangement ensures that the liquid water generated during the defrosting process of the heat exchanger 30 can flow more quickly from the water collection area 11 to the water pumping area 12. The water collection area 11 and the water pumping area 12 are inclined at an angle, further promoting the flow of liquid water generated during the defrosting process of the heat exchanger 30 from the water collection area 11 to the water pumping area 12. Figure 3 and Figure 4 The arrows shown indicate the direction of flow of liquid water generated during the defrosting process of heat exchanger 30.
[0041] Furthermore, a baffle plate 20 is provided on the side of the water collection area 11 away from the first side, and a heat exchanger 30 is provided on the side of the baffle plate 20 closer to the first side. The baffle plate 20 and the heat exchanger 30 are provided with a gap, preferably 'a', where 3mm ≤ a ≤ 8mm. The first end of the baffle plate 20 extends along the length direction of the first side, and the second end of the baffle plate 20 extends along the length direction of the second side. At least a portion of the baffle plate 20 is located above the water collection area 11, and the water pump assembly 50 is connected to the baffle plate 20. In this embodiment, the baffle 20 is also positioned near the fan blades to shield the wind pressure generated by the fan blades' rotation and prevent the liquid water generated during the defrosting process of the heat exchanger 30 from failing to flow from the water collection area 11 to the water pumping area 12. The baffle 20 maintains a uniform gap with the heat exchanger 30 but does not obstruct the heat exchanger 30, thus preventing the liquid water generated during the defrosting process from flowing to the top of the baffle 20 and causing icing. It also ensures that the liquid water in the water pumping area 12 is discharged from the chassis 10 through the water pump assembly 50. Alternatively, the baffle 20 can be directly positioned at the bottom of the fan blades, which also effectively shields the wind pressure generated by the fan blades' rotation and promotes the rapid flow of liquid water generated during the defrosting process of the heat exchanger 30 from the water collection area 11 to the water pumping area 12.
[0042] like Figure 1 and Figure 3 As shown, the second end of the wind deflector 20 is provided with two mounting sections 21, both of which extend along the length of the second side. One of the mounting sections 21 is located close to the second side, while the other mounting section 21 is located away from the second side. The water pump assembly 50 is connected to the two mounting sections 21. This arrangement makes the chassis assembly structure simple and compact.
[0043] In another embodiment of this application, intercepting steps 14 are provided on both the side of the water collection area 11 away from the first side and the side of the water collection area 11 away from the second side. The first end of the baffle plate is connected to the intercepting step 14, and the installation section 21 away from the second side of the two installation sections 21 is connected to the intercepting step 14. The intercepting step 14 isolates the near-fan blade area from the water collection area 11, thus preventing the liquid water generated during the defrosting process of the heat exchanger 30 from flowing out of the water collection area 11 and the pumping area 12 and into the near-fan blade area.
[0044] like Figure 2 and Figure 3As shown, the chassis assembly includes an electric heater 40, at least a portion of which is disposed within the water collection area 11, and the electric heater 40 extends along the length of the water collection area 11, thereby preventing the liquid water generated during the defrosting process of the heat exchanger 30 from condensing into ice. The electric heater 40 is not limited to the tubular structure shown in the figure; it can also be a strip-shaped soft heating structure, as long as it can achieve the electric heating function.
[0045] Furthermore, the chassis 10 is provided with multiple support bosses 13, at least one of which protrudes into the water collection area 11 and is used to support the heat exchanger 30. Specifically, there are four support bosses 13. This arrangement creates a gap space between the heat exchanger 30 and the water collection area 11, which facilitates the rapid sliding of liquid water generated during the defrosting process of the heat exchanger 30 into the water collection area 11.
[0046] Furthermore, the water pump assembly 50 also includes a water pump bracket 53, a water pump 51, a water pipe 52, and a water pump cover 54. The water pump bracket 53 is connected to two mounting sections 21. The water pump 51 has an inlet end 511 and an outlet end 512. The inlet end 511 is connected to the water pump bracket 53, and the water pipe 52 is detachably connected to the outlet end 512. The water pump cover 54 is placed on top of the water pump 51. The water pump cover 54 serves to protect the water pump 51 to prevent excessive water droplets from splashing onto the water pump 51 and causing icing, which would affect the use of the water pump 51.
[0047] Furthermore, the two mounting sections 21 are arranged to form a mounting position with an opening on one side, and the inlet end 511 is located between the two mounting sections 21. A water suction port is provided at the end of the inlet end 511, and the water suction port is connected to the pumping zone 12. This prevents the liquid water in the pumping zone 12 from being blown away by the fan blades, thus avoiding the problem of the water pump 51 not being able to draw water. In this embodiment, the water pump 51 also has a heating function. The heating function needs to be activated when the water pump 51 is running to prevent the water pump 51 from freezing and becoming inoperable.
[0048] like Figure 7 and Figure 8 As shown, the water pump bracket 53 is equipped with a grille 531, which is arranged along the circumferential direction of the inlet end 511. The grille 531 intercepts impurities in the water flowing into the water pump 51, thereby realizing the water pumping function and water filtration function of the water pump assembly 50.
[0049] According to another specific embodiment of this application, an air conditioner is provided, including a chassis assembly, which is the chassis assembly described in the above embodiment. By using the chassis assembly described in the above embodiment, liquid water generated during the defrosting process of the outdoor heat exchanger 30 drips into the water collection area 11 of the chassis 10. Under the action of the electric heater 40, the liquid water does not condense and flows into the water extraction area 12 of the chassis 10 under the protection of the baffle plate 20. After being sucked by the water pump 51, it is discharged to the indoor side through a water pipe, thereby removing the liquid water generated during the defrosting process of the outdoor heat exchanger 30. With this chassis assembly, an additional drain pipe can be installed in places without drainage pipes, such as houses or apartments, meeting the installation requirements of air conditioners in such places. Furthermore, the liquid water generated during the defrosting process of the heat exchanger 30 will not flow to the area near the fan blades, thus avoiding problems such as the fan blades freezing due to condensation of liquid water, which could lead to the fan blades not operating or noise and damage caused by the collision between the fan blades and the ice.
[0050] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0051] In addition to the above, it should be noted that the terms "one embodiment," "another embodiment," and "embodiment" used in this specification refer to specific features, structures, or characteristics described in connection with that embodiment, which are included in at least one embodiment described in the general description of this application. The appearance of the same expression in multiple places in the specification does not necessarily refer to the same embodiment. Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this invention.
[0052] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
[0053] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
