The utility model provides a mobile air conditioner, mobile air conditioner can make the water in the water receiving tank assemble and arrange to outdoor heat exchanger from the outlet, reduces the water receiving tank and with the water exhaust resistance.

Referring to fig. 1 to 3, in an embodiment of the mobile air conditioner of the present invention, the mobile air conditioner includes a housing 100, an outdoor heat exchanger 300, and a middle partition 500. The housing 100 includes a chassis 110; the outdoor heat exchanger 300 is mounted on the base pan 110; the middle partition 500 is installed above the outdoor heat exchanger 300, the middle partition 500 is provided with a water receiving tank 510, the water receiving tank 510 is provided with a first tank surface 511 and a second tank surface 512 which are opposite to each other, the lower side edge of the first tank surface 511 is connected with the lower side edge of the second tank surface 512, a water outlet 513 (the water outlet 513 can refer to fig. 6) penetrates through the connection position of the first tank surface 511 and the second tank surface 512, the water outlet 513 is used for discharging water to the outdoor heat exchanger 300, and the lower side edge of the first tank surface 511 inclines towards the water outlet 513.

Specifically, the housing 100 further includes a front panel 120, a back panel 130, and a top panel 140 mounted on the bottom chassis 110. The casing 100 is provided with an indoor intake port 101, an indoor discharge port 102, an outdoor intake port 103, and an outdoor discharge port 104. The middle partition 500 is installed in the casing 100 and divides the inner cavity of the casing 100 into an indoor heat exchange cavity 105 and an outdoor heat exchange cavity 106, the indoor heat exchange cavity 105 communicates the indoor air inlet 101 with the indoor air outlet 102, and the outdoor heat exchange cavity 106 communicates the outdoor air inlet 103 with the outdoor air outlet 104.

The mobile air conditioner further includes an indoor heat exchanger 200, an outdoor heat exchanger 300, an indoor fan 400, and an outdoor fan (not shown). Wherein, the indoor heat exchanger 200 and the indoor fan 400 are disposed in the indoor heat exchange cavity 105. The outdoor heat exchanger 300 and the outdoor fan are disposed in the outdoor heat exchange chamber 106. When the mobile air conditioner works, the indoor fan 400 drives external air to enter the indoor heat exchange cavity 105 from the indoor air inlet 101, the external air forms outlet air after being subjected to heat exchange by the indoor heat exchanger 200, and the outlet air is blown out to the indoor environment from the indoor air outlet 102. Meanwhile, the outdoor fan drives the outside air to enter the outdoor heat exchange cavity 106, and the outside air is discharged to the outdoor environment through the exhaust pipe via the outdoor air outlet 104 after exchanging heat with the outdoor heat exchanger 300.

During the operation of the mobile air conditioner, the outdoor heat exchanger 300 is likely to generate condensed water, and the condensed water flows downward into the water receiving tank 510. Since the first groove surface 511 of the water receiving groove 510 is inclined toward the drain port 513, the first groove surface 511 actually corresponds to a flow guide surface. When the condensed water flows to the first groove surface 511, the condensed water is downwardly inclined by the first groove surface 511, introduced into the drain port 513, and discharged to the outdoor heat exchanger 300 through the drain port 513. When the water flows over the surface of the outdoor heat exchanger 300, heat exchange occurs with the outdoor heat exchanger 300 to take away heat of the outdoor heat exchanger 300, so that the heat dissipation effect of the outdoor heat exchanger 300 can be enhanced.

It should be noted that the first groove surface 511 may be a groove surface close to the indoor air inlet 101, or a groove surface far from the indoor air inlet 101. The drain port 513 may be a circular hole-shaped drain hole, or may be a thin strip-shaped drain slit, which is not limited specifically. In addition, the drain port 513 may be directly opposite to the outdoor heat exchanger 300 to directly discharge water onto the outdoor heat exchanger 300; of course, a drain line may be connected to the drain 513, through which the condensate is drained to the heat exchanger.

The technical scheme of the utility model, the hookup location department through first trough face 511 and second trough face 512 at water receiving tank 510 sets up outlet 513 to set up first trough face 511 towards outlet 513 slope, so that rivers can collect outlet 513 along the incline direction of first trough face 511, arrange outdoor heat exchanger 300 on through outlet 513. Therefore, the resistance of the water receiving tank 510 to the discharge of water is reduced, the water quantity of the water receiving tank 510 to the outdoor heat exchanger 300 is increased, and the heat dissipation efficiency of the outdoor heat exchanger 300 is improved.

Referring to fig. 4 to 6, in an embodiment, the indoor heat exchanger 200 is mounted on the middle partition 500, and the indoor heat exchanger 200 is located above the water receiving tank 510, so that the condensed water generated by the indoor heat exchanger 200 directly falls into the water receiving tank 510. In order to prevent the condensed water from freezing the indoor heat exchanger 200 and the middle partition 500, support plates 520 are disposed at opposite sides of the water receiving groove 510, and the support plates 520 are supported at the bottom of the indoor heat exchanger 200. The existence of the supporting plate 520 can effectively prevent the middle partition plate 500 from directly contacting the indoor heat exchanger 200, thereby preventing the temperature of the condensed water from being low, and the condensed water freezes the middle partition plate 500 and the indoor heat exchanger 200 together.

Further, the support plate 520 near the air intake side of the indoor heat exchanger 200 is provided with an intake air gap 521. The intake air blown through the intake side of the indoor heat exchanger 200 partially passes through the intake gap 521 and enters between the catch basin 510 and the bottom of the indoor heat exchanger 200. The air enters the indoor heat exchanger 200 from the bottom of the indoor heat exchanger 200, so that the air inlet surface area of the indoor heat exchanger 200 is increased, and the heat exchange efficiency of the indoor heat exchanger 200 is effectively improved.

Referring to fig. 4 to 6, in an embodiment, to improve the heat dissipation efficiency of the outdoor heat exchanger 300, the water outlet 513 is disposed above the air inlet end of the outdoor heat exchanger 300. Due to the design, water flows from the water outlet 513 to the windward end of the outdoor heat exchanger 300 directly, and flows to the air outlet end of the outdoor heat exchanger 300 under the driving force of the inlet air flow of the outdoor heat exchanger 300, in the process, the water flow is blown away, the area of the water flow flowing through the outdoor heat exchanger 300 is increased, and therefore the heat dissipation efficiency of the outdoor heat exchanger is improved.

In general, water flowing down from the outdoor heat exchanger 300 drops onto the base plate 110 and is discharged to the outside through the water discharge port 513 of the base plate 110, which is likely to cause waste of water resources. Here, in order to improve the utilization rate of water resources, the base plate 110 is provided with a water collecting tank (not shown), and the mobile air conditioner further includes a water pump (not shown) that communicates with the water collecting tank to supply water of the water collecting tank to the outdoor heat exchanger 300.

The water flowing down from the outdoor heat exchanger 300 drops to the bottom plate 110 and is collected in the water collecting tank, and the water in the water collecting tank can be conveyed to the outdoor heat exchanger 300 again through the water pump, so that the water is utilized to dissipate heat of the outdoor heat exchanger 300, the repeated recycling of the condensed water is realized, and the utilization rate of water resource waves is improved.

Referring to fig. 2, 4 and 5, for the installation manner of the middle partition board 500, the middle partition board 500 may be fixedly connected with the casing 100 or fixedly connected with the internal components of the mobile air conditioner. In one embodiment, the mobile air conditioner further includes a discharge scroll 600 installed on the base plate 110, and the middle partition 500 is installed on the top of the discharge scroll 600. The exhaust volute 600 is used to form an air duct communicating the outdoor heat exchange cavity 106 and the outdoor air outlet 104. The discharge scroll 600 is supported at the bottom of the middle partition 500.

Referring to fig. 2, 4 and 7, further, the mobile air conditioner further includes a motor bracket 700 mounted on the base plate 110, wherein the motor bracket 700 is used for mounting a motor, and the motor is connected to the outdoor fan. The motor bracket 700 is positioned at one side of the exhaust volute 600; one end of the middle partition 500 is fixedly connected to the top of the motor bracket 700. The motor bracket 700 supports the middle barrier 500 in cooperation with the discharge scroll 600, so that the middle barrier 500 is more stably installed.

As for the specific connection manner of the motor bracket 700 or the exhaust volute 600 and the middle partition plate 500, optionally, the motor bracket 700 or the exhaust volute 600 and the middle partition plate 500 may be connected and fixed by a screw structure or a snap structure.

Referring to fig. 4 and 7, in an embodiment, the mobile air conditioner further includes an electric control box 900. Generally, the electrical control pod 900 is mounted to the chassis 110. However, in this case, when the refrigerant leaks from the refrigerant circulation system (e.g., the indoor heat exchanger 200, the outdoor heat exchanger 300, or the compressor 800) of the mobile air conditioner, the refrigerant may sink down onto the base plate 110, and when the leaked refrigerant contacts the electronic control box 900, an accident such as an explosion may occur, which may cause a great safety hazard.

Therefore, in this embodiment, in order to reduce the above potential safety hazard, the mobile air conditioner further includes an electronic control box bracket 910, the electronic control box bracket 910 is mounted on the middle partition board 500, and the electronic control box 900 is mounted on the electronic control box bracket 910. That is, the electrical control box 900 is mounted to the middle upper portion of the mobile air conditioner through the electrical control box bracket 910. The refrigerant can descend to the chassis 110 and is not easy to contact the electric control box 900 at a higher position, so that accidents such as explosion are reduced, and potential safety hazards are reduced.

The shape and structure of water receiving tank 510 will be described specifically based on the shape of second tank surface 512. If the second slot surface 512 is vertically disposed, the first slot surface 511 and the second slot surface 512 are coupled to form a carabiner. If the second groove surface 512 is also disposed to be inclined toward the drain port 513, the first groove surface 511 and the second groove surface 512 are engaged to form a V shape. In addition, the water receiving trough 510 may also be funnel-shaped, and the first trough surface 511 and the second trough surface 512 enclose to form an integral conical surface.

In this embodiment, the lower side of the second groove surface 512 is inclined toward the drain port 513. The second groove surface 512 also effectively acts as a flow guide surface. When the water flows to the second groove surface 512, the water is guided into the drain port 513 by the second groove surface 512 in a downward inclination. The first groove surface 511 and the second groove surface 512 are matched, so that the area of the flow guide surface of the water receiving groove 510 is increased, more condensed water is guided to the water outlet 513, and the water discharge amount is increased.

The lower side of the first slot surface 511 and the lower side of the second slot surface 512 can be directly connected or connected by an arc transition. In this embodiment, the lower side of the first slot surface 511 is directly connected to the lower side of the second slot surface 512, and the first slot surface 511 and the second slot surface 512 are disposed at an included angle, so that the first slot surface 511 and the second slot surface 512 are disposed in a V shape. When the water flows from the first slot surface 511 (or the second slot surface 512) to the lower side edge thereof, the water directly converges and enters the water outlet 513, the converging distance is short, and the converging effect is better.

Referring to fig. 8 and 9, theoretically, the smaller the included angle (shown as α in fig. 9) formed between the first slot surface 511 and the second slot surface 512, the steeper the first slot surface 511 and the second slot surface 512 are, the stronger the flow guiding effect is. However, the water receiving volume of the water receiving tank 510 is also reduced accordingly. In order to ensure that the first slot surface 511 and the second slot surface 512 have a strong flow guiding effect, and the water receiving slot 510 can have a sufficient water containing volume, optionally, an included angle formed between the first slot surface 511 and the second slot surface 512 is not less than 140 ° and not more than 160 °. Such as but not limited to: 145 °, 148 °, 150 °, 155 °, 158 °, 160 °.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
