[0002] Existing mobile air conditioners will produce condensed water during the refrigeration process, and the condensed water will collect in the chassis. In order to prevent excessive condensed water from overflowing from the chassis, the chassis is usually equipped with a water-pumping motor and a liquid level switch (for water full protection). The water-pumping motor is fixed on the chassis, and the water-pumping motor drives the water-pumping flywheel to rotate, and the condensed water is pumped onto the fins. The condensed water absorbs heat during evaporation, thereby achieving the effect of cooling the condenser and improving the performance of the whole machine. Finally, the vaporized condensed water is discharged to the outside through the exhaust pipe.

[0003] When the ambient humidity is high during the actual operation of the mobile air conditioner, the evaporator will produce more condensed water. When the installation position of the water-pumping flywheel is vertically close to the condenser, the water-pumping flywheel will generate loud noise when it hits the condensed water vertically onto the fins, and there is a chance that the condensed water will pass through the fins and hit the exterior parts, affecting the user experience.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0032] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0033] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0034] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0035] See also Figures 1 to 11 As shown, according to an embodiment of the utility model, a mobile air conditioner is provided, comprising an outer shell (not shown in the figure), the bottom of the outer shell having a chassis 1 and a condenser 2 assembled on the top surface of the chassis 1, and also comprising a compressor 52 fixedly assembled on the chassis 1, and an evaporator 51 located in the area above the condenser 2, the mobile air conditioner also having an upper air duct 53 and a lower air duct 54, a water collecting tank 11 and a compressor mounting seat 12 are constructed on the top surface of the chassis 1, the compressor 52 is assembled on the compressor mounting seat 12 through a shock-absorbing foot, and the chassis 1 is also provided with A water pumping assembly (not labeled in the figure), the water pumping assembly includes a water pumping flywheel 31 and a driving motor 32 for driving the water pumping flywheel 31 to rotate along the water pumping direction, the driving motor 32 is assembled on the top surface of the chassis 1, the water pumping flywheel 31 of the water pumping assembly is at least partially located in the water collecting tank 11 to pump out the condensed water in the water collecting tank 11, the condenser 2 has a first condensation portion 21 extending along a first direction and a second condensation portion 22 extending along a second direction, a bending angle is formed between the first condensation portion 21 and the second condensation portion 22, so that Figure 3 The orientation shown is for reference, the first direction is the left-right direction, and the second direction is the up-down direction. At this time, the bending angle is specifically 90°. It should be noted that the first direction and the second direction can of course also be other directions forming a certain angle. The water-flywheel 31 is arranged adjacent to the second condensation part 22. For details, see Figure 3As shown, the compressor mounting seat 12 is provided at the left side of the chassis 1 in the illustrated orientation, and the compressor 52 is assembled in this area. Based on the rationalization requirements of the spatial layout, the water-pumping flywheel 31 is arranged adjacent to the second condensing part 22 of the condenser 2. In practical applications, the horizontal distance between the outer ring of the water-pumping flywheel 31 and the second condensing part 22 is generally between 30 mm and 45 mm to ensure the horizontal width (in Figure 3 The orientation shown is for reference only) will not be too large and the structure will be more compact. Figure 8 As shown, the clockwise rotating water-pumping flywheel 31 pumps most of the condensed water to the first condensation part 21 to achieve efficient cooling of this part. At the same time, some condensed water on the water-pumping flywheel 31 will still be pumped to the second condensation part 22. Because it is too close to the aforementioned second condensation part 22, this small amount of condensed water is vertically pumped to the second condensation part 22, which on the one hand causes a larger collision noise here, and on the other hand, it will pass through the fins in the second condensation part 22 here and then hit the appearance part, reducing the user's experience. Therefore, in order to overcome the aforementioned deficiencies in the prior art, a noise reduction cover 4 is also provided on the chassis 1, and the noise reduction cover 4 has a noise reduction cavity (not marked in the figure) with an opening toward one side of the water-pumping flywheel 31, and a portion of the water-pumping flywheel 31 (that is, a portion of the water-pumping flywheel 31) extends into the noise reduction cavity so that the cavity wall of the noise reduction cavity is at least partially located between the water-pumping flywheel 31 and the second condensation part 22, and the highest point of the opening is not lower than the highest point of the water-pumping flywheel 31. The first condensation part 21 and the second condensation part 22 may be a series structure or a parallel structure of the refrigerant.

[0036] In this technical solution, a noise reduction cover 4 is arranged between the water-pumping flywheel 31 and the second condensation part 22, and the highest point of the opening of the noise reduction cover 4 is not lower than the highest point of the water-pumping flywheel 31, so that the noise reduction cover 4 can at least block the condensation water of the water-pumping flywheel 31 along the second condensation part 22 in the noise reduction chamber, effectively preventing the condensation water from directly hitting the second condensation part 22 vertically to form a large hitting noise, and at the same time, it can also effectively prevent this part of vertical condensation water from passing through the gaps between the fins of the second condensation part 22 and further splashing onto the appearance parts outside the second condensation part 22, thereby improving the user experience, and at the same time, it can also effectively prevent the loss of condensation water and improve the utilization rate of condensation water.

[0037] In some embodiments, the maximum concave length of the noise reduction cavity along the first direction is L, the length of the water-pumping flywheel 31 extending into the noise reduction cavity along the first direction is S, and S ≥ L / 2. For details, see Figure 4 As shown, the aforementioned first direction refers to the left and right direction of the orientation of the figure.

[0038] In this technical solution, it is ensured that there is a sufficiently large matching length between the water-pumping flywheel 31 and the noise reduction chamber, which can ensure the shielding and noise reduction effects on the water outflow on the right side of the water-pumping flywheel 31.

[0039] In some embodiments, due to the influence of factors such as processing accuracy and external force, the water-pumping flywheel 31 may produce position deviation in its operation. In order to reduce the influence of such deviation and ensure the normal operation of the water-pumping flywheel 31, the minimum gap between the water-pumping flywheel 31 and the inner wall of the noise reduction chamber is d, d≥3mm, thereby ensuring the safe operation of the water-pumping flywheel 31.

[0040] In some embodiments, the noise reduction cover 4 includes side walls 41 arranged corresponding to the two side end surfaces of the water-pumping flywheel 31, the two side walls 41 are arranged at intervals, and the two side walls 41 have a blocking wall 42 on the side away from the water-pumping flywheel 31, the blocking wall 42 and the side walls 41 are jointly arranged to form the noise reduction cavity, and the opening of the noise reduction cavity is on a vertical plane, and the vertical plane is parallel to the rotation axis of the water-pumping flywheel 31.

[0041] In this technical solution, two side walls 41 and a blocking wall 42 are used to enclose the aforementioned noise reduction cavity, wherein the opening of the noise reduction cavity is on a vertical plane, and the structural design is simple. In a preferred embodiment, the aforementioned noise reduction cover 4 is integrally formed on the chassis 1, and the opening of the aforementioned noise reduction cavity is on a vertical plane, which is conducive to smooth demolding during the integral molding process.

[0042] In some embodiments, the water-pumping flywheel 31 has a first plane (not shown in the figure, not labeled) passing through the midpoint of its thickness and parallel to one side end face of the water-pumping flywheel 31, the projection of the wall surface of the blocking wall 42 in the noise reduction cavity on the first plane has an arc segment (not labeled in the figure), the projection of the opening on the first plane is a first line segment (not labeled in the figure), the upper end point of the arc segment (not labeled in the figure) is connected to the upper end point of the first line segment (not labeled in the figure), the line between the upper end point and the lower end point (not labeled in the figure) of the arc segment is a second line segment (not labeled in the figure), the second line segment forms an angle a with the horizontal line, the opening of the angle a is away from the water-pumping flywheel 31, 90°≤α≤150°, the aforementioned arc segment The design can facilitate the smooth reflux of condensed water into the water collection tank 11, thereby improving the utilization rate of condensed water; and / or, the projection of the outer contour of the water-beating flywheel 31 on the first plane intersects with the first line segment at a first point (not marked in the figure), and the distance between the upper end point and the first point is A, 15mm≤A≤30mm, which can effectively block the condensed water part that can generate a large noise and is close to the second condensation part 22 by the water-beating flywheel 31. It can be understood that in this case, even if the condensed water that is above A on the right side of the water-beating flywheel 31 (that is, close to the second condensation part 22) collides with the second condensation part 22, it will not generate a large impact due to the large splashing distance, and the noise generated is within an acceptable range. Specifically, as shown in Table 1, when 90°≤α≤150° and 15mm≤A≤30mm, the noise level is low, and the water blocking effect and the reflux effect are both high.

[0043] Table 1 Water-pumping flywheel noise reduction experimental data

[0044]

[0045]

[0046] See also Fig. 9 and Fig.10 As shown, in some embodiments, the inner wall surface of the blocking wall 42 is provided with a water dividing rib 421, and the water dividing rib 421 is extended from top to bottom (when the mobile air conditioner is in use) to guide the condensed water hit thereon toward the side walls 41 on both sides of the water dividing rib 421. In this technical solution, the condensed water hit by the water-pumping flywheel 31 in the noise reduction chamber can be guided and separated toward the side walls 41 on the left and right sides thereof through the water dividing rib 421 extending from top to bottom, that is, most of the condensed water entering the noise reduction chamber will be guided to the inner wall surfaces of the two side walls 41 to flow back, so that the condensed water that flows back can be prevented from forming a large-area intersection with the condensed water that impacts the blocking wall 42, which can further reduce noise and ensure smooth reflux of condensed water.

[0047] In some embodiments, the cross-section of the water-dividing rib 421 is a pointed structure symmetrical about a second plane, and the second plane coincides with the first plane. The pointed structure can be, for example, an isosceles triangle. By arranging the coincidence of the symmetry plane of the pointed structure and the first plane, the condensed water struck by both sides of the water-beating flywheel 31 is more evenly diverted by the pointed structure to the side walls 41 on both sides, thereby ensuring the smooth fall of the condensed water.

[0048] In a further preferred embodiment, the opening has a water retaining flange (not shown and not labeled) approaching the first plane, that is, the water retaining flange extends a certain distance toward the inside of the opening. For example, water retaining flanges approaching each other are respectively arranged at the outer end surfaces of the two side walls 41, which can form a stop for the condensed water guided by the water dividing rib 421, preventing the condensed water guided toward both sides from splashing out of the opening onto the water-pumping flywheel 31 to form striking noise. At the same time, the water retaining flange can also make the opening further block the noise reduction chamber while meeting the insertion requirement of the water-pumping flywheel 31, thereby further weakening the transmission of the striking noise in the noise reduction chamber to the outside.

[0049] In a specific embodiment, the side wall 41 is inclined from top to bottom toward the side close to the first plane so that the width of the noise reduction cavity becomes smaller from top to bottom.

[0050] In this technical solution, when viewed from the direction facing the aforementioned opening, the opening has a structure that is larger at the top and smaller at the bottom. This can effectively prevent the condensed water at the top of the noise reduction chamber, especially in the top area of ​​the side wall, from falling freely from the top under the action of its own weight, causing a large backflow noise, while ensuring that this part of the condensed water can slide down along the guiding slope of the side wall 41.

[0051] As a preferred embodiment, the noise reduction cover 4 is a hollow structure. For example, the noise reduction cover 4 includes an inner shell and an outer shell that are spaced apart from each other, thereby further improving the sound insulation and noise reduction effect of the noise reduction cover 4. In a preferred embodiment, sound-absorbing material can also be filled between the inner shell and the outer shell. Of course, as another preferred embodiment, the noise reduction cover 4 is made of sound-absorbing material, that is, the noise reduction cover 4 is made of sound-absorbing material as a whole.

[0052] See Fig.11 As shown, the condenser 2 has two rows spaced apart from each other, and the water-pumping flywheel 31 and the noise reduction cover 4 are both located in the space between the two rows. Thus, by setting up a group of water-pumping flywheels 31, efficient cooling of the first condensation parts 21 of the two condensers 2 can be achieved, and the structure is simpler.

[0053] It is easy for those skilled in the art to understand that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0054] The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the utility model should be included in the protection scope of the utility model. The above is only a preferred implementation of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the utility model, and these improvements and variations should also be regarded as the protection scope of the utility model.
