Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a chassis assembly and an air conditioner. Background Technology

[0002] Water level switches typically control the operation of related equipment, such as the start and stop of a water pump, by detecting changes in water level. When the water level reaches or exceeds a preset position, the water level switch triggers a signal, causing the relevant equipment to perform the corresponding action. In related technologies, for ease of installation, the mounting bracket is fixed at one end, while the other end is supported only by constraints below (such as ribs or steps); the chassis has a water storage tank, allowing the water level switch to monitor the water level in the tank and perform the corresponding function at the preset water level. Currently, the water level switches function normally during product testing; however, after assembly and transportation, some products exhibited inaccurate water level monitoring, therefore this issue needs to be addressed. Utility Model Content

[0003] The main purpose of this utility model is to propose a chassis assembly and an air conditioner, which aims to enhance the stability and reliability of the water level switch after installation by fixing the two ends of the mounting bracket to the chassis, preventing it from shifting during transportation or normal operation, and ensuring the accuracy of water level monitoring.

[0004] To achieve the above objectives, the chassis assembly proposed in this utility model includes:

[0005] The chassis, including the water storage area; and

[0006] A water level switch assembly includes a mounting bracket and a water level switch mounted on the mounting bracket. Both lateral ends of the mounting bracket are fixed to the chassis, so that the water level switch is positioned above the water storage area to monitor the water storage area.

[0007] In one embodiment, the chassis is provided with a first fixing part and a second fixing part that are spaced apart from each other. The first fixing part and the second fixing part protrude from the surface of the chassis. The two lateral ends of the mounting bracket are respectively provided with a first mounting part and a second mounting part. The first mounting part and the first fixing part are connected and fixed together, and the second mounting part and the second fixing part are connected and fixed together.

[0008] In one embodiment, the first fixing part and the first mounting part are snapped together and fixed.

[0009] In one embodiment, the first fixing part is provided with an elastic buckle, and the first mounting part is provided with a buckle groove. The first fixing part and the first mounting part are engaged by the cooperation of the elastic buckle and the buckle groove.

[0010] In one embodiment, a first guide structure is further provided between the first fixing part and the first mounting part to guide the engagement of the elastic buckle and the buckle groove.

[0011] In one embodiment, the first guide structure includes a groove disposed on the first mounting portion, and the buckle groove is disposed in the groove; the first mounting portion sleeves the opposite sides of the first fixing portion through the groove, so that the elastic buckle and the buckle groove are engaged.

[0012] In one embodiment, the second fixing part and the second mounting part are snapped together.

[0013] In one embodiment, the second fixing part includes two fixing ribs spaced apart, with an installation opening defined between the two fixing ribs. Each fixing rib is provided with a slot, and the slots face each other. A locking block is provided on each of the opposite sides of the mounting bracket. A portion of the mounting bracket is placed inside the installation opening, and the locking block engages with the slot.

[0014] In one embodiment, a second guide structure is further provided between the second fixing part and the second mounting part to guide the engagement of the card block with the card slot.

[0015] In one embodiment, the second guide structure includes a guide slope disposed at the upper end of the fixing rib, and the two guide slopes of the two fixing ribs make the upper end of the mounting opening flared.

[0016] In one embodiment, the water level switch includes a high-level switch and a low-level switch, which are spaced apart along both ends of the mounting bracket. The bottom of the high-level switch is farther from the surface of the chassis than the bottom of the low-level switch.

[0017] This utility model also proposes an air conditioner, including an indoor unit and an outdoor unit, and a flexible refrigerant pipe connecting the indoor unit and the outdoor unit. The indoor unit includes a chassis assembly of any of the above-mentioned solutions.

[0018] In this invention, the water level switch is fixed above the water storage area by connecting it to the chassis via a mounting bracket to monitor the water level. Compared to related technologies, where the mounting bracket is fixed at one end for ease of installation, the other end is only supported by a constraint below (such as a rib or step). Although these methods function normally during testing, they can still shift during transportation or normal operation. This invention enhances the stability and reliability of the water level switch after installation, prevents it from shifting during transportation or normal operation, and ensures the accuracy of water level monitoring.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0033] Water level switches typically control the operation of related equipment, such as the start and stop of water pumps, by detecting changes in water level. When the water level reaches or exceeds a preset position, the water level switch triggers a signal, causing the relevant equipment to perform the corresponding action. In related technologies, for ease of installation, the mounting bracket is fixed at one end, while the other end is supported only by constraints below (such as ribs or steps). After multiple studies, it was found that this installation method may be relatively stable under static or normal operating conditions, but during transportation, due to the influence of external factors such as vibration and impact, the unfixed end of the water level switch is prone to displacement.

[0034] To address the aforementioned issues, this utility model proposes a chassis assembly for use in air conditioners, which can be the indoor unit of a split-type air conditioner or an integrated unit, such as a portable air conditioner.

[0035] Please see Figures 1 to 5In one embodiment of this utility model, the chassis 100 assembly includes a chassis 100 and a water level switch assembly 200. The water level switch assembly 200 includes a mounting bracket 201 and a water level switch mounted on the mounting bracket 201. In this embodiment, both ends of the mounting bracket 201 are fixed to the chassis 100 to maintain the distance between the bottom of the water level switch and the surface of the chassis 100 at a preset height. Understandably, since there is no additional constraint or support above the water level switch, it is prone to shifting vertically (i.e., upwards) during transportation when encountering bumps or vibrations. This shift not only affects the positional accuracy of the water level switch but may also lead to friction or collision with surrounding structures, further increasing the risk of damage. By fixing both ends of the mounting bracket 201 to the chassis 100, the stability and reliability of the water level switch after installation are enhanced, preventing shifting during transportation or normal operation and ensuring the accuracy of water level monitoring.

[0036] Taking the chassis 100 component as an example of the indoor unit of a portable air conditioner, the indoor unit includes the chassis 100.

[0037] The indoor unit of an air conditioner usually also includes a housing, which is connected to the chassis 100.

[0038] Air conditioner indoor units typically also include heat exchangers, such as evaporators, to absorb heat from the air, thereby achieving a cooling effect.

[0039] Air conditioner indoor units typically also include indoor fans, which create airflow, drawing in indoor air and exchanging heat through the evaporator before blowing it out from the air outlet.

[0040] Air conditioner indoor units typically also include electronic control systems, such as remote controls, transformers, ambient temperature and pipe temperature sensors, stepper motors, and other components.

[0041] Air conditioner indoor units typically also include auxiliary components, such as a drip tray: used to collect condensate produced during the cooling process and drain it outdoors through a water pipe to prevent condensate from dripping into the room and affecting users.

[0042] The chassis 100 is provided with a water storage area 101, which is a groove formed by the recess or excavation of the surface of the chassis 100 for water storage. The mounting bracket 201 is connected to the chassis 100 so that the water level switch is located above the water storage area 101. The height distance between the water level switch and the bottom of the groove is set according to the preset water level height to realize the monitoring function of the water level switch.

[0043] Reference Figure 3 and Figure 4Specifically, the chassis 100 has a first fixing part 110 and a second fixing part 120 spaced apart. The first fixing part 110 and the second fixing part 120 protrude from the surface of the chassis 100. Specifically, the first fixing part 110 protrudes from the edge of the water storage tank to facilitate the installation of the mounting bracket 201.

[0044] Reference Figure 5 The mounting bracket 201 has a first mounting portion 210 and a second mounting portion 220 at opposite ends. The first mounting portion 210 is connected and fixed to the first fixing portion 110, and the second mounting portion 220 is connected and fixed to the second fixing portion 120. Understandably, the first fixing portion 110 and the second fixing portion 120 are equivalent to two pillars, and the mounting bracket 201 acts as a "bridge" between them, thereby stabilizing the water level switch, preventing it from shifting during transportation or normal operation, and ensuring the accuracy of water level monitoring.

[0045] In this embodiment, the first fixing part 110 and the second fixing part 120 are integrally formed with the chassis 100, and the first fixing part 110 and the second fixing part 120 are configured as protruding ribs on the chassis 100. Of course, in other solutions, the first fixing part 110 and the second fixing part 120 may also be assembled on the chassis 100. Without loss of generality, the first fixing part 110 and the second fixing part 120 may also be configured as part of the mounting bracket 201, which is connected to the chassis 100 to fulfill the function of the water level switch monitoring the water storage area 101.

[0046] The horizontal ends of mounting bracket 201 (see) Figure 5 (Indicative direction) that is, the width direction of chassis 100 (e.g.) Figure 1 (Indicating direction).

[0047] There are several feasible solutions for connecting the first fixing part 110 and the first mounting part 210. For example, a bolted connection can be used, by providing corresponding threaded holes or through holes on the first fixing part 110 and the first mounting part 210 respectively, and using fasteners such as bolts, nuts, and washers to tightly connect them together. This method of connection is strong and can withstand greater external forces and vibrations, ensuring the stability of the water level switch.

[0048] Furthermore, if the material allows, the first mounting part 210 and the first fixing part 110 can also be connected together by welding. Welded connections are characterized by high strength and stable connection, and are suitable for applications requiring high connection strength. However, considering the need for ease of installation and disassembly, a snap-fit ​​fixing method is preferred in this solution.

[0049] Reference Figure 4 and Figure 5Specifically, the first fixing part 110 is provided with a resilient buckle 111, while the first mounting part 210 is provided with a locking groove. Through the cooperation of the resilient buckle 111 and the locking groove, the first fixing part 110 and the first mounting part 210 can be easily snapped together without the need for additional fasteners or tools. This connection method is not only easy to install, but also convenient to disassemble and reinstall, improving work efficiency. Of course, the resilient buckle 111 can be provided in the first mounting part 210, while the first fixing part 110 can be provided with a locking groove. The form of the buckle and locking groove is not limited, as long as it allows the first fixing part 110 and the first mounting part 210 to snap together.

[0050] To further enhance the stability of the connection, multiple elastic buckles 111 are designed on the first fixing part 110. These buckles are evenly distributed to ensure multi-point support when installing the bracket 201. Correspondingly, the first mounting part 210 is also provided with buckle slots that correspond exactly to the number of elastic buckles 111. Each buckle slot can precisely engage with the elastic buckle 111 to form a tight and stable connection.

[0051] This multi-point snap-fit ​​design not only significantly improves the connection strength, making the water level switch more stable after installation and less susceptible to external vibration or impact; at the same time, it simplifies the installation process, eliminating the need for complex fasteners or tools. Installation can be completed simply by aligning the slot 211 of the mounting bracket 201 with the buckle on the chassis 100 and pressing it down gently, thus improving work efficiency.

[0052] Furthermore, the multi-point snap-fit ​​design provides the mounting bracket 201 with a certain degree of fault tolerance. Even if a certain snap or slot wears or is damaged during long-term use, the other intact snaps and slots can still maintain the overall connection stability, avoiding the risk of the entire mounting structure failing due to a single point of failure. Multiple elastic snaps 111 are provided on the first fixing part 110, and the number of slots corresponds to the number of elastic snaps 111.

[0053] Optionally, two elastic buckles 111 are provided at intervals in the width direction of the first fixing part 110, and the two elastic buckles 111 are formed as part of the first fixing part 110.

[0054] The first fixing part 110 is a plate rib, and two elastic buckles 111 are formed on the plate surface. In order to improve the structural strength of the first fixing part 110, a reinforcing structure is also provided on the side of the first fixing part 110 away from the elastic buckles 111. The reinforcing structure extends from the elastic buckles 111 toward the chassis 100.

[0055] Reference Figure 4In this embodiment, the reinforcing structure is configured as reinforcing ribs of two triangular plates extending towards the chassis 100 from the self-elastic buckle 111. The two reinforcing ribs form a groove between each other, which helps to improve the structural strength of the first fixing part 110, prevent the deformation of the first fixing part 110 from affecting the water level switch, and ensure the accuracy of water level monitoring. Of course, in other solutions, the reinforcing structure can also be other configurations.

[0056] Furthermore, a first guide structure is designed between the first fixing part 110 and the first mounting part 210. This first guide structure guides the engagement of the elastic buckle 111 and the buckle groove. The first guide structure aims to precisely guide the engagement process between the elastic buckle 111 and the buckle groove, ensuring that the connection between the mounting bracket 201 and the chassis 100 is both quick and accurate.

[0057] Specifically, the first guide structure may exist in various forms, such as a guide groove, guide post, or guide ramp 223. The design principle of these structures is that, as the mounting bracket 201 approaches the chassis 100, they first contact and guide the mounting bracket 201 along a predetermined path until the elastic snap-fit ​​111 is fully aligned with the snap-fit ​​groove and successfully engages. The presence of the first guide structure greatly simplifies the installation process and reduces installation difficulties caused by improper operation or inaccurate alignment. At the same time, it also improves the reliability and stability of the installation, because even without precise alignment, the guide structure can correct deviations to a certain extent, ensuring successful engagement of the snap-fit ​​with the snap-fit ​​groove. Furthermore, the first guide structure helps protect the elastic snap-fit ​​111 from unnecessary wear or damage. During installation, the guide structure can disperse the impact force of the mounting bracket 201 on the elastic snap-fit ​​111, thereby extending its service life.

[0058] Reference Figure 5 In this embodiment, to simplify the installation process and improve the stability and accuracy of the connection, preferably, the first guide structure is configured with a groove 212 on the first mounting part 210, and a snap-fit ​​groove is provided within the groove 212; the first fixing part 110 is fitted onto the groove 212, and the first mounting part 210 slides through the groove 212 fitted onto the first fixing part 110, with the elastic snap-fit ​​111 engaging with the snap-fit ​​groove. The groove 212 designed on the first mounting part 210 not only provides a basis for guidance during the installation process, but also cleverly incorporates the snap-fit ​​groove, which is located inside the groove 212, waiting to engage with the elastic snap-fit ​​111 on the first fixing part 110.

[0059] The two sides of the first fixing part 110 perfectly match the sliding grooves 212 on the first mounting part 210, allowing the first mounting part 210 to slide smoothly along the sliding grooves 212 until it reaches the predetermined installation position. During this process, the sliding grooves 212 not only serve as guides but also ensure the relative positional accuracy between the first fixing part 110 and the first mounting part 210. When the first mounting part 210 slides to the predetermined position, the elastic buckle 111 and the buckle groove will accurately align and smoothly engage, achieving precise positioning between the mounting bracket 201 and the chassis 100. Furthermore, the first mounting part 210 has a guide opening at the sleeve end of the sliding groove 212 to facilitate the first mounting part 210 fitting into the first fixing part 110.

[0060] Specifically, the slide groove 212 of the first mounting part 210 is formed by protrusions on both sides of the end of the first mounting part 210, and the bottom of the slide groove 212 abuts and limits the end of the first fixing part 110, thereby restricting the relative movement of the first fixing part 110 and the first mounting part 210 and ensuring the connection between the elastic buckle 111 and the buckle groove.

[0061] There are several feasible solutions for connecting the second fixing part 120 and the second mounting part 220. For example, a bolted connection can be used, by providing corresponding threaded holes or through holes on the second fixing part 120 and the second mounting part 220 respectively, and using fasteners such as bolts, nuts, and washers to tightly connect them together. This method of connection is robust and can withstand greater external forces and vibrations, ensuring the stability of the water level switch.

[0062] Similar to the first mounting part 210 and the first fixing part 110, considering the need for ease of installation and detachability, the connection between the second fixing part 120 and the second mounting part 220 in this solution preferably adopts a snap-fit ​​fixing method.

[0063] In the current related solutions, for ease of installation, the water level switch assembly 200 is fixed at one end of the mounting bracket 201, and the chassis 100 only supports the other end of the mounting bracket 201 without constraining it from above. As a result, it is easy for it to deviate during transportation, which will cause the height of the supporting end to shift, thus affecting the accuracy of water level monitoring.

[0064] In this design, the first mounting part 210 and the first fixing part 110, the second mounting part 220 and the second fixing part 120 are all fixed by snap-fit, which enhances the stability and reliability of the water level switch 202 after installation, prevents it from shifting during transportation or normal operation, and ensures the accuracy of water level monitoring.

[0065] Reference Figure 4Preferably, the second fixing part 120 includes two fixing ribs 221 spaced apart. Specifically, one fixing rib 221 is located on the side wall of the water storage tank, and the other fixing rib 221 is connected to the side wall of the water storage tank by a connecting plate. The two fixing ribs 221 are at approximately the same height, that is, the height of the fixing rib 221 with the connecting plate inside the water storage tank is the same as the height of the fixing rib 221 located at the edge of the side wall of the water storage tank. The first fixing part 110 is located at the edge of the side wall of the water storage tank. The first fixing part 110 and the two fixing ribs 221 are arranged in a triangle, and the three are at approximately the same height. This ensures that the mounting bracket 201 is relatively horizontal after installation, so as to control the distance between the water level switch 202 and the water storage tank and ensure the long-term accuracy of water level monitoring.

[0066] In addition, an installation opening 222 is defined between the two fixing ribs 221. The installation opening 222 serves as a clearance mechanism, and the end of the mounting bracket 201, when placed into the installation opening 222, also provides a guiding function during installation. Both fixing ribs 221 have a slot 211 formed at their ends away from the chassis 100, with the slots facing each other. The mounting bracket 201 has a locking block 230 on each side of the first mounting portion 210 from the direction of the second mounting portion 220. A portion of the mounting bracket 201 is placed within the installation opening 222, and the locking block 230 engages with the slot 211. It should be noted that defining the installation opening 222 between the two fixing ribs 221 is not only based on considerations of ease of installation and disassembly, but also because the locking mechanism effectively prevents the component from moving or shifting after installation, thereby ensuring the long-term accuracy of water level monitoring. This ensures that the mounting bracket 201 has sufficient space for locking while also ensuring the compactness and stability of the structure.

[0067] In addition, at the ends of the two fixing ribs 221 that are away from the chassis 100, slots 211 are formed. The openings of these two slots 211 face each other, providing a precise mating position for the mounting block 230 of the bracket 201.

[0068] During installation, a portion of the mounting bracket 201 is placed within the mounting opening 222 defined by two fixing ribs 221. Subsequently, through precise alignment, the locking block 230 on the mounting bracket 201 engages with the locking groove 211 on the second fixing part 120. This locking method is not only stable and reliable but also facilitates disassembly and reinstallation. This locking method significantly improves the stability of the water level switch 202 after installation. Even during transportation or long-term use, the components are less prone to shifting, thus ensuring the accuracy of water level monitoring.

[0069] A second guide structure is also provided between the second fixing part 120 and the second mounting part 220 to guide the locking block 230 to engage with the locking groove 211. The second guide structure may exist in various forms, such as a guide groove, a guide post, or a guide ramp 223. The design principle of these structures is that, during the process of the mounting bracket 201 approaching the chassis 100, the locking block 230 of the mounting bracket 201 can first contact and guide the locking block 230 of the mounting bracket 201 to be fully aligned with the locking groove 211 and engage smoothly.

[0070] Reference Figure 4 Specifically, the second guide structure is a guide slope 223, which is formed by the fixed rib 221 tilting from the end toward the chassis 100. The two guide slopes 223 of the two fixed ribs 221 make the mounting opening 222 flared from the direction away from the chassis 100. The guide slope 223 is connected to the slot 211 at the end in the tilt direction.

[0071] The two guide ramps 223 work together to make the mounting opening 222 (i.e., the opening where the mounting bracket 201 connects with the chassis 100) flare outwards from the direction away from the chassis 100. This helps to more easily guide the locking block 230 into the locking slot 211 when the mounting bracket 201 approaches the chassis 100, and even if there is a certain deviation in the initial position, it can be gradually adjusted to the correct position by the guidance of the ramps.

[0072] As the mounting bracket 201 approaches the chassis 100, the groove 212 of the first mounting part 210 engages with the first fixing part 110, while the locking block 230 of the second mounting part 220 contacts the guide ramp 223 of the second fixing part 120. The ramp guides the locking block 230 of the mounting bracket 201 to gradually move along the ramp to a position perfectly aligned with the slot 211. When the locking block 230 is perfectly aligned with the slot 211 under the guidance of the guide ramp 223, the mounting bracket 201 can be smoothly pressed down or pushed, allowing the locking block 230 to enter the slot 211 and lock in place. This process is usually accompanied by a clicking sound or tactile feedback, indicating that the engagement is complete. The design of the guide ramp 223 simplifies the installation process, reduces the number of adjustments needed due to inaccurate alignment, and thus improves installation efficiency.

[0073] Reference Figure 4Specifically, in this embodiment, the fixing rib 221 is a triangular rib formed by the intersection of two plate-like ribs, which provides good stability and strength. The sides of the two triangular ribs that are close to each other have a support platform (not shown in the figure) that abuts against the locking block 230. The support platform acts as a lower constraint on the mounting bracket 201, while the side bends outward from the upper part of the support platform to form a bent section. The bent section is triangular in shape, and the guide slope 223 is the hypotenuse of the bent section. The bent section and the support platform are misaligned in the vertical projection direction, and a locking groove 211 is defined between the bent section and the support platform. The design of the bent section improves the stability of the structure, thereby improving the firmness of the locking. The support platform abuts against part of the locking block 230 along the direction from the first mounting part 210 to the second mounting part 220 of the mounting bracket 201, while the bent section locks into another part of the locking block 230, ensuring the stability of the locking block 230 in the installation direction. During the installation process, the locking block 230 is first guided into the locking groove 211 by the guide slope 223. As the locking block 230 advances further, the support platform begins to abut against a portion of the locking block 230, while the bent section gradually locks the other part of the locking block 230. Finally, the locking block 230 is stably fixed in the slot 211, achieving a secure connection of the mounting bracket 201.

[0074] In some cases, a single water level switch may generate a false alarm due to factors such as water level fluctuations, air bubbles, or impurities. (Combined with...) Figure 5 In order to improve the accuracy of water level monitoring, the water level switch 202 includes a high-level switch 210 and a low-level switch 220. The high-level switch 210 and the low-level switch 220 are spaced apart along both ends of the mounting bracket 201. The bottom of the high-level switch 210 is farther from the surface of the chassis 100 than the distance of the low-level switch 220.

[0075] The length of the mounting bracket 201 is aligned with the direction from the first fixing part 110 to the second fixing part 120 on the chassis 100. The high-position switch 210 and the low-position switch 220 are spaced apart laterally along the mounting bracket 201. This layout ensures the independence of the water level switches 202 while facilitating their uniform fixing on the chassis 100.

[0076] During installation, the mounting bracket 201 engages with the two reinforcing ribs from top to bottom. The first mounting portion 210 and the first fixing portion 110 of the mounting bracket 201 are guided by a sliding groove 212 and a slider, and secured by an elastic buckle 111 and a locking groove. The other end is limited by a locking block 230 at the end of the second fixing portion 120 by a locking groove 211. In this way, the mounting bracket 201 and the water level switch 202 mounted on it are firmly fixed vertically, preventing upward displacement due to vibrations during transportation or normal operation. By setting two water level switches, water levels at different heights can be monitored separately. When the water level rises, the two water level switches can be triggered sequentially, providing more accurate water level information.

[0077] This utility model also proposes an air conditioner, which includes a chassis 100 assembly. The specific structure of the chassis 100 assembly is as described in the above embodiments. Since the chassis 100 assembly adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0078] In this embodiment, the air conditioner is configured as a split-type unit, including an indoor unit, an outdoor unit, and a flexible refrigerant pipe connecting the two units. To facilitate individual installation, the indoor and outdoor units are connected by the flexible refrigerant pipe, and refrigerant is injected into the refrigerant circuit before the equipment leaves the factory. Thus, when a user installs the equipment themselves, they only need to fix the indoor and outdoor units separately, without needing to assemble the refrigerant pipe or add refrigerant, thereby reducing installation difficulty and enabling individual installation. Alternatively, placing the compressor in the indoor unit can reduce the weight of the outdoor unit, making it easier for users to move the outdoor unit to a suitable installation location, reducing installation difficulty and labor costs, especially in areas with high labor costs. Optionally, after placing the compressor in the indoor unit, noise reduction structures and / or soundproof covers can be added between the compressor and the chassis 100 to reduce noise during operation and improve the user experience. However, this design is not limited to this; in other embodiments, the air conditioner can also be configured as an integrated unit, such as a portable air conditioner or a window air conditioner.

[0079] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
