[0035] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary. The embodiments of the present utility model will be described in detail below.

[0036] Below, refer toFigures 1-10 Describe a shielding component 100 for a window air conditioner 200 according to an embodiment of the present invention. It can match windows of different widths, and can also achieve a wide-area fresh air exchange effect between the indoor and outdoor through a filter screen 31, and can also play a role in dust prevention and mosquito prevention during the fresh air exchange process.

[0037] Combined with Figures 1-10 As shown, the shielding component 100 for the window air conditioner 200 according to the first aspect embodiment of the present invention is provided on one side of the window air conditioner 200, and the shielding component 100 is used to shield the gap between the window and one side of the window air conditioner 200.

[0038] For example, the shielding component 100 can be provided on both sides in the horizontal direction of the window air conditioner 200 (such as Figure 1 shown on the left and right sides, or it can also be on both sides or one side in the up and down direction, and is not limited thereto). Its main function is to shield the gap between the window and the window air conditioner 200, that is, to separate the inner and outer sides of the window, so as to achieve the effects of sealing, sound insulation, dust prevention, rain and snow prevention, and foreign object prevention for the inner side of the window.

[0039] Specifically, the shielding component 100 includes a first shielding plate 1 and a second shielding plate 2. The first shielding plate 1 is connected to the window, the second shielding plate 2 is slidably connected to the first shielding plate 1, the second shielding plate 2 is movable relative to the first shielding plate 1, and the second shielding plate 2 is connected to the window air conditioner 200.

[0040] Specifically, the first shielding plate 1 and the second shielding plate 2 are slidably connected together so as to be movable relative to each other, and the first shielding plate 1 and the second shielding plate 2 are respectively connected to the window and the window air conditioner 200. In this way, the window air conditioner 200, the shielding component 100 and the window can be connected as a whole, so that a stable installation and fixing effect can be formed on the shielding component 100, and the effect of shielding the gap between the window and the window air conditioner 200 can be achieved.

[0041] Furthermore, the second shielding plate 2 is movable relative to the first shielding plate 1, so that the relative position of the first shielding plate 1 and the second shielding plate 2 in the moving direction can be changed, thereby achieving the effect of changing the overall width (that is, the left and right direction) dimension of the shielding component 100.

[0042] In particular, the first baffle 1 and the second baffle 2 can change their relative positions under the external force of the user. That is, the user can adjust the first baffle 1 and the second baffle 2 accordingly according to the windows of different width dimensions (that is, the overall width of the shielding component 100 is adapted to the gap width between the window and one side of the window air conditioner 200) to a matching position, so that the shielding component 100 realizes the effect of adjustable overall width, thereby improving the versatility and adaptability of the shielding component 100.

[0043] For example, the shielding component 100 can be in a stretched or contracted state. Along the moving direction of the second baffle 2, when the shielding component 100 is in a stretched state, the relative distance between the first baffle 1 and the window air conditioner 200 is farther, and the shielding area is larger at this time; when the shielding component 100 is in a contracted state, the relative distance between the first baffle 1 and the window air conditioner 200 is closer, and the shielding area is smaller at this time.

[0044] In summary, according to different window widths, the user can adjust the relative positions between the first baffle 1 and the second baffle 2 to match, so as to effectively improve the installation versatility and convenience of the shielding component 100.

[0045] Wherein, at least one of the first baffle 1 and the second baffle 2 includes a base body 3 and a filter screen 31. The base body 3 mainly plays a role of structural support and forms the outer contour of the shielding component 100; the filter screen 31 has the functions of filtering large particulate dust in the air (dust prevention), preventing mosquitoes and preventing sundries, etc., so as to achieve the effect of air purification.

[0046] For example, the filter screen 31 can be a common PP net, a silver ion net, a mildew-proof net, etc., which is not limited thereto.

[0047] In addition, the filter screen 31 is connected to the base body 3, and the filter screen 31 is formed with a plurality of filter holes 311, and the outdoor fresh air is suitable for entering the room through the plurality of filter holes 311. For example, the filter screen 31 and the base body 3 can be connected together by welding, bonding and other methods.

[0048] The base body 3 can provide a stable supporting and installation condition for the filter screen 31 to ensure the position stability of the filter screen 31. The outdoor fresh air and the indoor stale air can be naturally exchanged through the plurality of filter holes 311 on the filter screen 31, so as to achieve the effect of exchanging fresh air without opening the window.

[0049] Moreover, compared with the mechanical built-in fresh air exchange device (which is installed inside the air conditioner and has a relatively small fresh air exchange cross-sectional area due to space limitations), in the embodiments of this case, the fresh air exchange device (i.e., the shielding component 100) is externally disposed on one side of the window air conditioner 200. In this way, it is not restricted by the inherent space inside the window air conditioner 200, and its fresh air exchange cross-sectional area is wider, thereby improving the efficiency of fresh air exchange.

[0050] Compared with the electric fresh air exchange device (which requires a motor to drive and has a relatively complex structure), in the embodiments of this case, the fresh air exchange device (i.e., the shielding component 100) is externally disposed on one side of the window air conditioner 200. In this way, it can take into account the gap between the window and one side of the window air conditioner 200 and the effect of natural fresh air exchange, with a simpler structure, and has the advantages of simplified operation, safety and reliability, and low cost.

[0051] Compared with the sliding fresh air control device (which has air vents but no filter screen, so it cannot prevent large dust particles, floating objects, mosquitoes, etc. from entering the indoor side), in the embodiments of this case, a filter screen 31 is provided on at least one of the first shielding plate 1 and the second shielding plate 2. In this way, it can prevent large dust particles, mosquitoes and sundries from entering the indoor side, thereby effectively improving the quality of fresh air entering the room.

[0052] Thus, by providing the shielding component 100, it can match windows of different widths, and can also achieve a wide-area fresh air exchange effect between the indoor and outdoor through the filter screen 31, and play a role in dust prevention and mosquito prevention during the fresh air exchange process.

[0053] According to some alternative embodiments of the present invention, in combination with Figure 7 and Figure 8 as shown, the base body 3 includes a base plate 32 and a frame 33. The filter screen 31 is connected to the base plate 32, and the frame 33 is connected to the edge of the base plate 32. For example, the filter screen 31 and the base plate 32 can be connected together by welding, bonding or other means.

[0054] Wherein, the frame 33 is connected to the edge of the base plate 32 in the circumferential direction. The frame 33 and the base plate 32 can increase each other's weight and spatial mode, thereby improving the structural strength and bending and torsional stiffness of the two; moreover, the frame 33 can also play a role in protecting the base plate 32.

[0055] In addition, the base plate 32 is configured as a plate shape, and the filter screen 31 is provided on the base plate 32. In this way, it is convenient for the filter screen 31 to be smoothly installed on the base plate 32, and it is also convenient for the filter screen 31 to be arranged on the plate-shaped base plate 32 in a large area, thereby improving the layout rationality.

[0056] The frame 33 of the first baffle 1 is connected to the window, and the frame 33 of the second baffle 2 is connected to the window air conditioner 200. With such an arrangement, on the one hand, the effective width dimensions of the first baffle 1 and the second baffle 2 can be fully utilized to avoid waste of processing consumables. On the other hand, the connection contact areas between the first baffle 1 and the second baffle 2 and the window and the window air conditioner 200 can be increased respectively, thereby improving the connection stability.

[0057] Specifically, as shown in combination with Figure 7 and Figure 8 , through holes are formed in the substrate 32, the filter screen 31 is located in the through holes, and the edge of the filter screen 31 is connected to the substrate 32.

[0058] It can be understood that the edge of the filter screen 31 is connected to the inner wall of the through hole. In this way, the through hole can provide an installation space for the filter screen 31 and avoid the filter screen 31 additionally occupying the space in the thickness direction of the substrate 32 (that is, the front-back direction), thereby improving the space utilization rate.

[0059] Furthermore, as shown in combination with Figure 7 , Figure 9 and Figure 10 , the first sliding part 331 is arranged on the frame 33 of the first baffle 1, the second sliding part 332 is arranged on the frame 33 of the second baffle 2, and the first sliding part 331 and the second sliding part 332 are in sliding fit.

[0060] That is to say, the first sliding part 331 on the first baffle 1 and the second sliding part 332 on the second baffle 2 are in sliding fit with each other. In this way, the moving direction of the second baffle 2 can be guided and it can move along a specified path, thereby improving the moving smoothness and accuracy when the first baffle 1 moves relative to the second baffle 2.

[0061] In addition, the first baffle 1 and the second baffle 2 establish a sliding fit relationship through the first sliding part 331 and the second sliding part 332. In this way, the second baffle 2 can adjust the relative position between the first baffle 1 and the second baffle 2 by sliding relative to the first baffle 1, thereby achieving the effect of flexibly adjusting the overall width dimension of the shielding assembly 100, and further achieving the effect of matching windows of different widths.

[0062] Specifically, the area of one side surface of the substrate 32 is S1, the area of one side surface of the filter screen 31 is S2, and S1 and S2 satisfy the relational expression: 0.5S1 ≤ S2 < S1.

[0063] It can be understood that in the front-rear direction, since the filter screen 31 is disposed on the substrate 32, the area of one side surface of the filter screen 31 is larger than the area of one side surface of the substrate 32 (that is, S2 < S1). In this way, it can be prevented that the filter screen 31 is too large and exceeds the coverage range of the substrate 32, thereby ensuring the effectiveness and rationality of the arrangement of the filter screen 31.

[0064] Among them, in the front-rear direction, the area of one side surface of the filter screen 31 is not less than half of the area of one side surface of the substrate 32 (that is, 0.5S1 ≤ S2). In this way, it can be ensured that the filter screen 31 has a large air change cross-sectional area, thereby ensuring the air change efficiency; if the area of one side surface of the filter screen 31 is too small, it may cause the problem of low air change efficiency. Therefore, 0.5S1 ≤ S2 is made.

[0065] Preferably, 0.7S1 ≤ S2. In this way, on the one hand, the air change cross-sectional area of the filter screen 31 can be increased, and on the other hand, it can be ensured that the substrate 32 surrounding the outer periphery of the filter screen 31 has good structural strength, thereby improving the structural reliability and air change efficiency of the shielding assembly 100.

[0066] Further preferably, 0.85S1 ≤ S2. In this way, on the premise of ensuring that the substrate 32 surrounding the outer periphery of the filter screen 31 meets the structural strength requirements, the air change cross-sectional area of the filter screen 31 can be further increased, thereby effectively improving the air change efficiency.

[0067] According to some alternative embodiments of the present invention, in combination with Figure 4 As shown, the shielding assembly 100 for the window air conditioner 200 further includes a sealing plate 4. The sealing plate 4 is detachably installed on one side of the first shielding plate 1 and the second shielding plate 2. The sealing plate 4 is used to shield the filter screen 31.

[0068] Specifically, in the front-rear direction, the sealing plate 4 is detachably shielded on the side of the first shielding plate 1 and the second shielding plate 2 facing the room under the action of an external force. In this way, the sealing plate 4 can be flexibly disassembled and assembled according to the user's fresh air change demand.

[0069] Among them, when the sealing plate 4 shields one side of the first shielding plate 1 and the second shielding plate 2, it can have a sound insulation and sealing effect on the room; when the sealing plate 4 exposes the filter holes 311 on the first shielding plate 1 and the second shielding plate 2, the air inside and outside the room can perform normal natural air change work, thereby realizing the fresh air change effect in the room.

[0070] Specifically, in combination with Figure 4 and Figure 5 As shown, an installation groove 5 is formed on one side of the first shielding plate 1 and the second shielding plate 2, and the sealing plate 4 is installed in the installation groove 5.

[0071] It can be understood that in the front-rear direction, on the sides of the first baffle 1 and the second baffle 2 facing the interior, an installation groove 5 is jointly formed. The installation groove 5 can provide an installation and accommodation space for the sealing plate 4, thereby improving the layout rationality of the shielding assembly 100.

[0072] According to some alternative embodiments of the present invention, the filter net 31 and the base body 3 are integrally formed. In this way, compared with the split assembly, the process of integrally forming the filter net 31 and the base body 3 can increase the overall stability and structural reliability.

[0073] For example, the filter net 31 can also be a separate mesh part (made integrally with the base body 3 or separately disassembled), or a mesh feature on the base body 3.

[0074] Optionally, as shown in Figure 5 the first baffle 1 further includes a mounting plate 11, and the mounting plate 11 is connected to the frame 33 at the top of the base plate 32.

[0075] It can be understood that the mounting plate 11 on the first baffle 1 is provided with mounting holes, and fasteners can pass through the mounting holes and the window to connect the first baffle 1 and the window as a whole, thereby enhancing the connection strength between the shielding assembly 100 and the window frame 33. Among them, the mounting plate 11 is connected to the frame 33 at the top of the base plate 32, which can enhance the structural strength of each other.

[0076] In addition, the mounting plate 11 is provided with a direction mark in the direction facing the inner side of the window, which can play an anti-fooling role during the installation process of the grouped shielding assemblies 100 to avoid reverse installation. For example, the direction mark can be left, right, L, R, etc., and is not limited thereto.

[0077] Another alternative is that the second baffle 2 is provided with a plug-in portion 21 on the frame 33 on the side facing the window air conditioner 200. The plug-in portion 21 is in plug-in fit with the window air conditioner 200. Compared with other connection methods (such as welding, screwing or bonding), the plug-in connection method in this application can make the connection process simpler, more flexible and convenient on the basis of the firm connection between the shielding assembly 100 and the window air conditioner 200, thereby effectively improving the installation convenience and flexibility between the shielding assembly 100 and the window air conditioner 200.

[0078] According to some alternative embodiments of the present invention, the filter net 31 is one of a polypropylene filter net, a nylon filter net and a metal filter net.

[0079] For example, a polypropylene filter screen has the advantages of good chemical stability (able to withstand the corrosion and erosion of various chemical substances and not easily affected by chemical reactions), high filtration efficiency (small pore size, high filtration accuracy, able to effectively filter out fine particles and impurities in the liquid, improving filtration efficiency and purity), easy replacement and cleaning, and low cost. Therefore, using a polypropylene filter screen can improve the purification rate of fresh indoor air and also reduce production costs.

[0080] Another example is that a nylon filter screen has good mechanical strength (nylon material has high tensile and compressive strength, good toughness, and is suitable for withstanding high pressure and mechanical shock), chemical resistance, and corrosion resistance. Moreover, it has low resistance when fluid passes through and can be reused. Therefore, using a nylon filter screen can improve the filtration efficiency of fresh indoor air and also reduce the long-term use cost.

[0081] For yet another example, a metal filter screen has strong durability (metal materials such as stainless steel and aluminum have high strength and wear resistance characteristics, making the metal filter screen have a long service life) and can be cleaned and regenerated (the metal filter screen is easy to disassemble and clean, can be reused repeatedly, and reduces the subsequent replacement cost). Therefore, using a metal filter screen can improve its service life and practicality.

[0082] The window air conditioner 200 assembly according to the second aspect embodiment of the present utility model includes a window air conditioner 200 and the shielding assembly 100 for the window air conditioner 200 in the above embodiment. The shielding assembly 100 is respectively installed on opposite sides of the window air conditioner 200. Thus, applying the shielding assembly 100 to the window air conditioner 200 can facilitate users to match windows of different width sizes, thereby improving the installation convenience and versatility of the shielding assembly 100. It can also achieve a wide-area fresh air exchange effect between the indoor and outdoor through the filter screen 31, and play a role in preventing dust and mosquitoes during the fresh air exchange process.

[0083] The installation process of the shielding assembly 100 in this case: Fix the installation bracket (depending on actual installation or not) - Place the window air conditioner 200 on the installation bracket (or on the window) and adjust the position - Insert the left / right shielding assemblies 100 into both sides of the window air conditioner 200 respectively - Expand the left / right shielding assemblies 100 to match both sides of the window - Fix the left / right shielding assemblies 100 to the window with screws - Finally, pull down the sliding window (until it presses against the top of the window air conditioner 200 and the top of the left / right shielding assemblies 100).

[0084] The window air conditioner 200 includes an indoor unit and an outdoor unit. The indoor unit and the outdoor unit are connected by pipelines to transfer refrigerant. The indoor unit includes an indoor heat exchanger and an indoor fan. The outdoor unit includes a compressor, a four-way valve, an outdoor heat exchanger, an outdoor fan, and an expansion valve. The compressor, the outdoor heat exchanger, the expansion valve, and the indoor heat exchanger connected in sequence form a refrigerant circuit, and the refrigerant circulates in the refrigerant circuit, and exchanges heat with air through the outdoor heat exchanger and the indoor heat exchanger respectively to achieve the cooling mode or the heating mode of the air conditioner.

[0085] The compressor is configured to compress the refrigerant so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0086] The outdoor heat exchanger is configured to exchange heat between the outdoor air and the refrigerant flowing in the outdoor heat exchanger. For example, the outdoor heat exchanger operates as a condenser in the cooling mode of the air conditioner, so that the refrigerant compressed by the compressor dissipates heat to the outdoor air through the outdoor heat exchanger and condenses. The outdoor heat exchanger operates as an evaporator in the heating mode of the air conditioner, so that the decompressed refrigerant absorbs heat from the outdoor air through the outdoor heat exchanger and evaporates.

[0087] In some embodiments, the outdoor heat exchanger further includes heat exchange fins to increase the contact area between the outdoor air and the refrigerant flowing in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0088] The outdoor fan is configured to suck the outdoor air into the outdoor unit through the air inlet of the outdoor unit, and send the outdoor air that has exchanged heat with the outdoor heat exchanger out through the air outlet of the outdoor unit. The outdoor fan provides power for the flow of the outdoor air.

[0089] The expansion valve is connected between the outdoor heat exchanger and the indoor heat exchanger. The opening degree of the expansion valve adjusts the refrigerant pressure flowing through the outdoor heat exchanger and the indoor heat exchanger to adjust the refrigerant flow rate between the outdoor heat exchanger and the indoor heat exchanger. The flow rate and pressure of the refrigerant flowing between the outdoor heat exchanger and the indoor heat exchanger will affect the heat exchange performance of the outdoor heat exchanger and the indoor heat exchanger. The expansion valve can be an electronic valve. The opening degree of the expansion valve is adjustable to control the flow rate and pressure of the refrigerant flowing through the expansion valve.

[0090] The four-way valve is connected in the refrigerant circuit. The four-way valve is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the air conditioner executes the cooling mode or the heating mode.

[0091] The indoor heat exchanger is configured to exchange heat between the indoor air and the refrigerant flowing through the indoor heat exchanger. For example, in the cooling mode of the air conditioner, the indoor heat exchanger operates as an evaporator, enabling the refrigerant that has dissipated heat through the outdoor heat exchanger to absorb the heat of the indoor air and evaporate through the indoor heat exchanger. In the heating mode of the air conditioner, the indoor heat exchanger operates as a condenser, enabling the refrigerant that has absorbed heat through the outdoor heat exchanger to release the heat to the indoor air and condense through the indoor heat exchanger.

[0092] In some embodiments, the indoor heat exchanger further includes heat exchange fins to increase the contact area between the indoor air and the refrigerant flowing through the indoor heat exchanger, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

[0093] The indoor fan is configured to suck the indoor air into the indoor unit through the air inlet of the indoor unit and send out the indoor air that has exchanged heat with the indoor heat exchanger through the air outlet of the indoor unit. The indoor fan provides power for the flow of the indoor air.

[0094] The air conditioner further includes a control device. The control device is configured to control the operating frequency of the compressor, the opening degree of the expansion valve, the rotational speed of the outdoor fan, and the rotational speed of the indoor fan. The control device is connected to the compressor, the expansion valve, the outdoor fan, and the indoor fan through data lines to transmit communication information.

[0095] The control device includes a processor. The processor may include a central processing unit (CPU), a microprocessor, or an application specific integrated circuit (ASIC), and may be configured to perform the corresponding operations described in the control device when the processor executes a program stored in a non-transitory computer-readable medium coupled to the control device. The non-transitory computer-readable storage medium may include a magnetic storage device (e.g., a hard disk, a floppy disk, or a magnetic tape), a smart card, or a flash memory device (e.g., an erasable programmable read-only memory (EPROM), a card, a stick, or a thumb drive).

[0096] The other configurations and operations of the vehicle according to the embodiments of the present invention are known to those of ordinary skill in the art and will not be described in detail herein.

[0097] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "center", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings.
