Description

Parking air conditioner, control method for parking air conditioner and vehicle

Technical Field

The invention relates to the technical field of air conditioners, in particular to a parking air conditioner, a control method for the parking air conditioner and a vehicle.

Background

The parking air conditioner can conveniently convey cold air or hot air into the compartment of the motor home, so that the temperature and the humidity in the compartment are adjusted, a comfortable compartment environment is provided for drivers and passengers, trip fatigue is reduced, and driving safety is ensured. The existing parking air conditioner may be broadly classified into an overhead air conditioner, a bottom air conditioner, a rear air conditioner, and the like according to the arrangement positions. The overhead air conditioner has the advantages of convenience in installation, space saving in a car, good refrigerating effect and the like, so that the overhead air conditioner is mostly adopted in the motor home.

Currently, an overhead parking air conditioner generally includes a base, an upper case, a lower case, and the like. The upper shell is fixed on the upper part of the base to enclose an accommodating space for installing functional components such as a compressor, a condenser, an evaporator, an indoor fan, an outdoor fan, an electric element and the like. An air outlet communicated with the external environment is arranged on the upper shell. Taking a refrigeration working condition as an example, the outdoor fan can timely discharge hot air on the condenser from the air outlet. The lower housing is fixed at the lower part of the base and extends into the compartment of the caravan. The lower housing is provided with the air return opening and the air inlet which are spaced from each other, so that air in the carriage can enter the parking air conditioner from the air return opening under the drive of the indoor fan and exchange heat with the evaporator for refrigeration, and then flows back into the carriage again from the air inlet, so that the temperature in the carriage is reduced.

Due to the special structure of the overhead parking air conditioner, rainwater, snow water and the like in the external environment inevitably enter the interior of the parking air conditioner from the air outlet. In order to prevent water from entering the interior of the carriage from the return air inlet or the air inlet and simultaneously avoid damaging functional parts (particularly electric elements) fixed on the base due to disordered water flowing on the base, water blocking ribs are usually arranged on the base in the prior art. However, when special conditions such as large rainwater, unsmooth drainage, large road gradient are met, water on the base can overflow the manger plate muscle, leads to leaking, electrical components short circuit etc. the condition, has greatly influenced user's use experience and parking air conditioner's life.

Accordingly, there is a need in the art for a new solution to the above-mentioned problems.

As shown in fig. 1 to 5, in one or more embodiments, the parking air conditioner 20 of the present invention includes a base 21, an upper case 24, a lower cover 25, a liquid level detecting device 22, and an angle adjusting device 23. The upper case 24 is fixed to an upper portion of the base 21 to define a receiving space for mounting the functional components. The functional components include, but are not limited to, a compressor, a condenser, an expansion device, an evaporator, and the like (not shown) which are sequentially connected through refrigerant lines to form a refrigeration circuit in which refrigerant (e.g., R34a, etc.) is allowed to circulate. In one or more embodiments, the functional components further include a four-way valve that can adjust the flow direction of the refrigerant, so that the parking air conditioner 20 has both a cooling function and a heating function.

As shown in fig. 2 and 3, in one or more embodiments, the base 21 includes a base plate 211 and a circumferential wall 212 that are connected to each other. The base plate 211 and the circumferential wall 212 may be integrally molded by an injection molding process using a suitable resin material (e.g., PP, PE, ABS, etc.) to simplify the manufacturing process. The substrate 211 has a substantially rectangular shape. Alternatively, the substrate 211 may also take a square shape or other suitable shape. The circumferential wall 212 extends vertically upward from the circumferential edge of the base plate 211 so as to be connected with the upper case 24.

With continued reference to fig. 1-3, the base 21 has an end 21a extending generally in a left-right direction. Based on the orientation shown in fig. 2, the end 21a is the rear end of the base 21. Alternatively, the end portion 21a may be provided as the front end of the base 21. The base 21 is rotatably fixed to the roof 10 about an end 21a. In one or more embodiments, bearings (not shown) opposite to each other in the left-right direction are provided on the roof 10, and a rotation shaft (not shown) insertable into the corresponding bearings is provided on the end portion 21a. Alternatively, the pivot connection between the end 21a and the roof 10 may be formed in other suitable ways. With the above arrangement, the base 21 is rotatably fixed to the roof 10, and can extend in the left-right direction along the rotation axis.

With continued reference to fig. 2 and 3, the substrate 211 has a wet region 2111 proximate the end 21a and a dry region 2112 distal the end 21a. Based on the orientation shown in fig. 2, the wet region 2111 is located on the rear side of the substrate 211, while the dry region 2112 is located on the front side of the substrate 211. A compressor, an evaporator, an outdoor fan (not shown) coupled to the evaporator, and the like may be installed on the wet area 2111. On the dry area 2112, a condenser, an indoor fan matched with the condenser, an electric element (not shown), and the like may be installed. A first water deflector bar 2113 is provided between the wet area 2111 and the dry area 2112. The first water deflector bar 2113 extends substantially in the left-right direction. In one or more embodiments, the first water deflector bar 2113 has a generally "zig-zag" shape and projects toward the end 21a. Such an arrangement facilitates water in the wet area 2111 to flow along the first water blocking rib 2113 toward the left and right sides of the base plate 211 to improve drainage efficiency. The first water blocking rib 2113 extends vertically upward from the upper surface of the base plate 211 by a certain height so as to effectively block water of the wet area 2111. It should be noted that the height of the first water barrier 2113 may be selected according to practical needs, for example, 5cm, 5.5cm, 6cm, etc.

With continued reference to fig. 2 and 3, in one or more embodiments, the dry section 2112 includes a buffer section 2112a, a tunnel section 2112b, and an electrical control section 2112c, which are connected in sequence. Wherein the buffer zone 2112a is adjacent to the wet zone 2111, the electronically controlled zone 2112c is remote from the wet zone 2111, and the air duct zone 2112b is interposed between the buffer zone 2112a and the air duct zone 2112b. The buffer area 2112a is arranged, so that the air channel area 2112b and the electric control area 2112c are separated from the wet area 2111 by a certain distance, and water in the wet area 2111 is prevented from directly flowing to the air channel area 2112b and the electric control area 2112c once overflowing from the first water retaining rib 2113, so that a certain buffer effect is achieved. The air duct section 2112b may be mated with the lower housing 25 so as to be in air communication with the interior of the cabin. The electric control area 2112c is used for mounting various electric elements. Electrical components include, but are not limited to, capacitors, frequency converters, integrated circuits, and the like.

With continued reference to fig. 2 and 3, in one or more embodiments, an air intake 2118 proximate the buffer 2112a, an air return 2117 proximate the electronic control 2112c, and a water pan 2119 between the air intake 2118 and the air return 2117 are provided on the air chute 2112b. In one or more embodiments, the intake vents 2118 include 2 spaced apart from each other in the left-right direction. Each intake opening 2118 has a generally rectangular shape. Alternatively, the number of the air intake holes 2118 may be set to 1, 3, or other suitable number. In one or more embodiments, the return air holes 2117 include 7 spaced apart from each other in the left-right direction. Each return air hole 2117 has a generally rectangular shape. Alternatively, the number of return air holes 2117 may be set to other suitable numbers, such as 6, 8, etc., more or less than 7. The water receiving tray 2119 extends in a substantially right-left direction. The condenser is disposed at an upper portion of the water-receiving tray 2119 such that condensed water flowing down from the condenser can be effectively collected by the water-receiving tray 2119, preventing the condensed water from flowing out of order on the base plate 211. In one or more embodiments, a plurality of water guide ribs 21191 are provided on the water receiving tray 2119 to be spaced apart from each other so as to guide water in the water receiving tray 2119 to both left and right sides of the base plate 211, thereby improving drainage efficiency.

With continued reference to fig. 2 and 3, in one or more embodiments, a second water deflector 2114 is provided between the buffer region 2112a and the wind tunnel region 2112b. The second water deflector rib 2114 extends in a substantially lateral direction and is adjacent to the air inlet hole 2118. In one or more embodiments, the second water barrier 2114 has a substantially "figure" shape and protrudes toward the end 21a so that water in the buffer 2112a can also flow along the second water barrier 2114 toward the left and right sides of the base 211 to improve drainage efficiency. The second water blocking rib 2114 extends vertically upward from the upper surface of the base plate 211 by a certain height. In one or more embodiments, the height of the second water barrier 2114 is greater than the height of the first water barrier 2113 such that water within the wet area 2111, even if spilled over the first water barrier 2113, is effectively blocked by the second water barrier 2114 from entering the air duct area 2112b and the electrical control area 2112c.

With continued reference to fig. 2 and 3, in one or more embodiments, a third water deflector 2115 is provided between the wind tunnel region 2112b and the electrical control region 2112c. The third water deflector rib 2115 extends in a substantially lateral direction and is adjacent to the return air hole 2117. The third water blocking rib 2115 can further separate the air channel region 2112b and the electric control region 2112c, so that water in the air channel region 2112b is prevented from entering the electric control region 2112c, and a safe and reliable working environment is provided for electrical components in the electric control region 2112c. The third water blocking rib 2115 extends vertically upward from the upper surface of the base plate 211 by a certain height. In one or more embodiments, the height of the third water barrier 2115 is lower than the height of the first water barrier 2113. Because the water in the air duct area 2112b overflows from the third water retaining rib 2115 and enters the electric control area 2112c, the height of the third water retaining rib 2115 is reduced appropriately, the utilization rate of the component can be improved, and the material cost of the product can be reduced.

With continued reference to fig. 2 and 3, in one or more embodiments, a plurality of drain holes 2116 are provided on the left and right sides of the substrate 211, respectively. These drain holes 2116 are distributed at intervals of each other on the wet area 2111, the buffer area 2112a and the air channel area 2112b so as to rapidly drain water of a corresponding area. It should be noted that the shape, size, number and arrangement of the drain holes 2116 may be selected according to actual needs.

As shown in fig. 2, in one or more embodiments, a plurality of first fixing holes 2121 are provided on the circumferential wall 212 that are circumferentially spaced apart from each other. Each of the first fixing holes 2121 may be mated with a corresponding second fixing hole 2421 on the upper housing 24 so as to fix the base 21 and the upper housing 24 together by a suitable fastener (e.g., a bolt, a nut, etc.). The number of first fixing holes 2121 may be 7, or other suitable number greater or less than 7. In one or more embodiments, a plurality of snap-fit holes 2122 are also provided on the circumferential wall 212 spaced apart from the first securing holes 2121. Each of the snap holes 2122 has a generally rectangular shape. Alternatively, the snap holes 2122 may be provided in a square, circular, or other suitable shape. Each of the clamping holes 2122 may be matched with a corresponding clamping block 2422 on the upper housing 24 to improve the assembly efficiency and the stability of the connection between the upper housing 24 and the base 21.

As shown in fig. 2, a liquid level detecting device 22 is disposed on the base 21 to detect the water level of the wet zone 2111. The liquid level detection device 22 may be in communication with a control system (not shown) of the parking air conditioner 20 to transmit a detection signal to the control system. In one or more embodiments, the liquid level detection device 22 is disposed on a vertical wall of the first water deflector bar 2113 that faces the wet area 2111. Since the distribution of water in the wet area 2111 may be uneven and the water in the wet area 2111 needs to pass over the first water barrier 2113 to enter the dry area 2112 with a high probability, the liquid level detection device 22 may be disposed on the vertical wall of the first water barrier 2113 facing the wet area 2111 to more accurately detect the water level in the wet area 2111. In one or more embodiments, the fluid level detection device 22 is a float gauge. Alternatively, the level detection device 22 may employ a differential pressure type level gauge, a capacitive type level gauge, an ultrasonic type level gauge, a magnetic flap type level gauge, or other suitable level detection device.

As shown in fig. 1, the angle adjusting device 23 is fixed to the roof 10 and connected to the base 21. In one or more embodiments, the angle adjustment device 23 is disposed on a side remote from the end 21a. Based on the orientation shown in fig. 2, the angle adjusting device 23 is arranged on the front side of the base 21 to drive the base 21 to rotate around the end 21a more effort-saving. Alternatively, the angle adjusting means 23 may be provided at other suitable positions. In one or more embodiments, the angle adjustment device 23 is a hydraulic lever. Alternatively, the angle adjusting device 23 may be a pneumatic rod, an electric push rod or other suitable driving device. The angle adjusting device 23 is in communication with a control system of the parking air conditioner 20 such that the angle adjusting device 23 can drive the base 21 to rotate upward about the end 21a by a predetermined angle when the water level of the wet area 2111 measured by the liquid level detecting device 22 exceeds a predetermined water level. In one or more embodiments, the ratio between the height of the predetermined water level and the height of the first water barrier 2113 ranges from 1/2 to 4/5. Further, the ratio between the height of the predetermined water level and the height of the first water baffle ribs 2113 is 3/4. In one or more embodiments, the predetermined angle ranges from 10 ° to 20 °. Further, the predetermined angle is 15 °. Therefore, when the water level in the wet area 2111 exceeds a predetermined water level (for example, when special conditions such as large rainwater, unsmooth drainage, large road gradient are encountered), the parking air conditioner 20 of the invention can actively control the base 21 to rotate upwards by a predetermined angle, and properly raise the dry area 2112, so that the water in the wet area 2111 flows in the direction of the end 21a (i.e., the direction away from the dry area 2112), and the water is ensured not to overflow the first water blocking rib 2113 and enter the dry area 2112.

In one or more embodiments, as shown in fig. 4, the upper housing 24 includes a top wall 241 and a circumferential skirt 242 extending vertically downward from a circumferential edge of the top wall 241. The top wall 241 and the peripheral skirt 242 may be integrally formed by an injection molding process using a suitable resin material (e.g., PP, PE, ABS, etc.). The top wall 241 has 2 exhaust outlets 2411 formed therein to be spaced apart from each other in the left-right direction. Each of the exhaust outlets 2411 has a substantially circular shape. In the assembled state, the exhaust holes 2411 are located above the wet area 2111 of the chassis 21. Each of the exhaust outlets 2411 may be matched with a corresponding outdoor fan so as to exhaust hot air or cold air on the evaporator. It should be noted that the shape, number and size of the exhaust ports 2411 may be adjusted according to actual needs.

With continued reference to fig. 4, in one or more embodiments, a plurality of second securing holes 2421 are provided in the circumferential skirt 242 that are circumferentially spaced apart from one another.

Next, an embodiment of a control method for a parking air conditioner according to the present invention will be described with reference to fig. 6. The control method may be used in the parking air conditioner 20 or the vehicle 1 having the parking air conditioner 20 as described in any one of the above.

Fig. 6 is a flowchart illustrating an embodiment of a control method for a parking air conditioner according to the present invention. As shown in fig. 6, in one or more embodiments, after the control method for the parking air conditioner 20 of the present invention is started, step S1, i.e., detecting the water level of the wet area 2111 of the base 21 of the parking air conditioner 20, is first performed. In one or more embodiments, the water level in the wet zone 2111 can be detected by a liquid level detection device 22 disposed on the base 21. Next, step S2 is performed to compare the measured water level with a predetermined water level. In one or more embodiments, the ratio between the height of the predetermined water level and the height of the first water barrier 2113 ranges from 1/2 to 4/5. Further, the ratio between the height of the predetermined water level and the height of the first water baffle ribs 2113 is 3/4. When the water level exceeds the predetermined water level, the control base 21 is rotated upward by a predetermined angle. Specifically, the base 21 is driven to rotate upward around the end 21a by a predetermined angle by an angle adjusting device 23 disposed at the end 21a distant from the base 21. In one or more embodiments, the predetermined angle is in the range of 10 ° -20 °. Further, the predetermined angle is 15 °. Accordingly, the control method of the present invention can actively control the base 21 to be rotated upward by a predetermined angle when the water level of the wet area 2111 exceeds a predetermined water level, and appropriately raise the dry area so that the water in the wet area 2111 flows toward the end 21a, ensuring that the water does not enter the dry area 2112.

Thus far, the technical solution of the present invention has been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of protection of the present invention is not limited to these specific embodiments. Equivalent modifications and substitutions for related technical features may be made by those skilled in the art without departing from the principles of the present invention, and such modifications and substitutions will fall within the scope of the present invention.
