Description
Technical Field
[0001] The utility model relates to the technical field of parking air conditioners, in particular to a cooling and heating type parking air conditioner. Background Art
[0002] The car air conditioning system can provide a comfortable riding environment for passengers, reduce the driver's fatigue and improve driving safety. Nowadays, air conditioning has become one of the signs to measure whether the car's functions are complete. During long-distance transportation, the driver of a cargo truck needs to rest when he is tired. Although the truck is equipped with air conditioning, the engine needs to be started. The fuel cost of starting the truck engine ranges from 25 to 50 yuan per hour. In addition, the engine is noisy and not environmentally friendly. In this way, various parking air conditioners came into being. Parking air conditioners are air conditioners that can run independently without relying on the vehicle engine power when the car is parked. Compared with traditional car air conditioners, parking air conditioners can reduce engine wear, greatly save fuel costs and reduce environmental pollution.
[0003] Common parking air conditioners generally do not have a heating function, which greatly limits the use environment of the parking air conditioner. Therefore, it is necessary to add a heating element to the parking air conditioner. However, when the heating element in the existing cold and warm type parking air conditioner heats the air, generally a large amount of air is directly in contact with the heating element as a whole, so that the heating element heats the large amount of air for a long time, resulting in low heating efficiency and high energy consumption of the heating element. Therefore, a cold and warm type parking air conditioner that can reduce the heating time is needed. Utility Model Content
[0004] The utility model aims to provide a cold-heating parking air conditioner which can reduce the heating time.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cooling and heating type parking air conditioner, comprising an outer shell, a mounting plate is installed in the middle of the inner part of the outer shell, a cylinder is fixedly provided on the upper side of the mounting plate, a first shell with an opening facing upward is fixedly provided on the upper side of the cylinder, a fan is provided inside the first shell, a condenser is installed on one side of the upper part of the mounting plate, two air vents are respectively provided on both sides of the outer shell, a bottom plate is detachably provided on the lower side of the inner part of the outer shell, a heating assembly is provided on the upper side of the bottom plate, the heating assembly comprises an air box, a second shell is fixedly provided on the upper side of the air box, a PTC heating device is slidably provided inside the second shell, a plurality of partitions are fixedly provided on both sides of the PTC heating device at staggered intervals inside the second shell, and a wavy channel is formed inside the second shell through the cooperation of the PTC heating device and the plurality of partitions.
[0006] Among them, the wavy channel in the second shell is used to extend the distance that the air moves in the second shell, so that the air can contact the PTC heating device repeatedly, so that the temperature of the air in the second shell can be quickly increased. The thermal resistance of the PTC heating device is smaller than that of other heating elements. Under no circumstances will the surface of the electric heating tube heater turn red. Moreover, when the fan fails, the PTC heating device will automatically stop working to avoid further temperature rise due to insufficient heat dissipation, and the probability of fire is lower.
[0007] Preferably, the interior of the first shell is connected to the interior of the cylinder and is provided with a plurality of through holes, the interior of the cylinder is connected to the interior of the condenser and is provided with a first connecting pipe, a first solenoid valve is connected between the first connecting pipe and the interior of the cylinder, the interior of the cylinder is connected to one end of the wavy channel inside the second shell and is provided with a second connecting pipe, and the second connecting pipe is connected to the interior of the cylinder and is provided with a second solenoid valve.
[0008] Preferably, two side panels are fixedly provided at both ends of the mounting plate, two first exhaust pipes are provided inside the condenser and are connected to the two vents, respectively, and the two first exhaust pipes pass through the two side panels, respectively, and the mounting plate and the two side panels are both made of insulating material. The mounting plate and the two side panels are both made of insulating material to prevent the cold air and the warm air generated by the condenser and the heating assembly from affecting each other.
[0009] Preferably, the other end of the wavy passage inside the second shell is connected to the interior of the air box and is provided with a through opening, and two sides of the air box are respectively connected to the two vents and are provided with two second exhaust pipes.
[0010] Preferably, the distance between adjacent partitions inside the second shell decreases continuously from one end in the direction of the second connecting pipe to one end in the direction of the through-port, and the space of the wavy channel inside the second shell toward the second connecting pipe is larger, while the space of the wavy channel inside the second shell toward the through-port is smaller.
[0011] Preferably, the PTC heating device includes a circuit connection end shell, a frame is fixedly provided on one side of the circuit connection end shell, a plurality of mounting grooves are provided on the frame, a heating element is provided in each mounting groove, a slider is fixedly provided on one side of each partition facing the frame, a plurality of slide grooves are staggered and spaced on both sides of the frame, and each slider slides in the slide groove.

[0013] Preferably, two filter plates are fixedly disposed inside the two vents respectively.
[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] The wavy channel in the second shell extends the distance that the air moves in the second shell, so that the air can repeatedly contact the PTC heating device, thereby quickly increasing the temperature of the air in the second shell. The thermal resistance of the PTC heating device is smaller than that of other heating elements. Under no circumstances will the surface of the heater, such as the electric heating tube, turn red. Moreover, when the fan fails, the PTC heating device will automatically stop working to avoid further temperature rise due to insufficient heat dissipation, and the probability of fire is even lower. Most PTC heating devices are composed of ceramic heating elements and aluminum tubes, which have the advantages of simple structure and low price. Even if the PTC heating device of the vehicle is damaged, the subsequent replacement and maintenance costs are also very cheap.
[0016] A larger amount of air passes through the wavy channel in the second shell toward the second connecting pipe, and a smaller amount of air passes through the wavy channel in the second shell toward the opening, so that the space for the air to move in the wavy channel is continuously reduced, thereby reducing the amount of air heated by the PTC heating device, so that the air can be heated quickly, so that the PTC heating device can cooperate with the wavy channel in the second shell to quickly heat the air, thereby reducing the time the PTC heating device heats the air.

[0036] Further, such as Figure 6 As shown, the distance between adjacent partitions 30 inside the second shell 20 decreases continuously from one end in the direction of the second connecting pipe 21 to one end in the direction of the through opening 41, and the space of the wavy channel inside the second shell 20 toward the side of the second connecting pipe 21 is larger, and the space of the wavy channel inside the second shell 20 toward the side of the through opening 41 is smaller.
[0037] Further, such as Figure 4 , Figure 6 As shown, the PTC heating device 24 includes a circuit connection end housing 45, a frame 32 is fixedly provided on one side of the circuit connection end housing 45, a plurality of mounting grooves 46 are provided on the frame 32, a heating element 44 is provided in each mounting groove 46, a slider 31 is fixedly provided on one side of each partition 30 facing the frame 32, a plurality of slide grooves 33 are staggered and spaced on both sides of the frame 32, and each slider 31 slides in the slide groove 33.
[0038] Further, such as Figure 8-9 As shown, two card slots 34 are respectively provided at both ends of the frame 32, and two push rods 36 are respectively slidably provided at both ends of the second shell 20. One end of each push rod 36 is in sliding contact with the card slot 34. An annular member 37 is sleeved on the outer side of each push rod 36. Each annular member 37 slides in the end wall of the second shell 20. A spring 38 is connected between each annular member 37 and the end wall of the second shell 20.
[0039] Further, such as Figure 1 , Figure 6 As shown, two filter plates 11 are fixedly arranged inside the two air vents 29 .
[0040] When in use, the staff pulls out the two push rods 36 to both sides, so that the two push rods 36 slide to both sides, and the sliding of the push rods 36 drives the ring member 37 to slide outward, thereby squeezing and compressing the spring 38 to generate elastic force; then the staff makes the multiple slide grooves 33 on the frame 32 correspond to the multiple sliders 31 one by one, and the staff pushes the line connection end shell 45 to make the frame 32 enter the second shell 20, and the frame 32 slides in the second shell 20 to cooperate with the multiple sliders 31 to slide in the slide grooves 33, so that the frame 32 moves smoothly in the second shell 20. At this time, the staff releases the two push rods 36, and the elastic forces of the two springs 38 act on the two annular members 37 respectively, so that the two annular members 37 move toward each other. The movement of the two annular members 37 drives the two push rods 36 to move toward each other, so that the inner ends of the two push rods 36 enter the two slots 34 respectively, so that the frame 32 is limited and fixed in the second shell 20 through the cooperation of the slot 34 and one end of the push rod 36. Finally, the staff connects the power supply line to the line connection end shell 45, and connects one end of the second connecting pipe 21 to the second shell 20. The staff installs the heating assembly and the base plate 25 on the shell 10.
[0041] When the cold air is discharged, the fan 13 starts to suck the air outside the shell 10 into the first shell 12, and the air in the first shell 12 enters the cylinder 15 through the multiple through holes 28. At this time, the first solenoid valve 26 is opened and the second solenoid valve 27 is closed, so that the air in the cylinder 15 enters the first connecting pipe 18 through the first solenoid valve 26, and the air in the first connecting pipe 18 enters the condenser 17, and the air is cooled by the condenser 17. The cooled cold air enters the two sides of the shell 10 through the two first exhaust pipes 19 respectively, and finally the cold air is discharged through the two vents 29, thereby cooling the interior of the car, so that the driver can deliver cold air in time when parking in summer, thereby improving the driver's comfort.
[0042] When the warm air is discharged, the fan 13 starts to suck the air outside the housing 10 into the first shell 12, and the air in the first shell 12 enters the cylinder 15 through the multiple through holes 28. At this time, the second solenoid valve 27 is opened and the first solenoid valve 26 is closed, so that the air in the cylinder 15 enters the second connecting pipe 21 through the second solenoid valve 27, and the air in the second connecting pipe 21 enters the larger end of the wavy channel in the second shell 20, so that the air in the cylinder 15 can quickly pass through the second connecting pipe 21 into the second shell 20; at this time, the power supply circuit in the air box 22 energizes the multiple heating elements 44, so that the multiple heating elements 44 are energized to generate heat. At this time, the air flows in the wavy channel in the second shell 20, and the wavy channel in the second shell 20 prolongs the distance that the air moves in the second shell 20, so that the air contacts the PTC heating device 24 repeatedly, so that the temperature of the air in the second shell 20 can be quickly increased.
[0043] At the same time, the space through the wavy channel in the second shell 20 toward the second connecting pipe 21 is larger, so that the amount of air in the wavy channel in the second shell 20 toward the second connecting pipe 21 is larger, and then the space through the wavy channel in the second shell 20 toward the opening 41 is smaller, so that the amount of air in the wavy channel in the second shell 20 toward the opening 41 is smaller, so that the space for the air to move in the wavy channel in 20 is continuously reduced, so that the amount of air heated by the PTC heating device 24 is continuously reduced, so that the air is quickly heated in the second shell 20, so that the PTC heating device 24 cooperates with the wavy channel in the second shell 20 to quickly heat the air, thereby reducing the time for the PTC heating device 24 to heat the air. The air in the second shell 20 is quickly heated and enters the air box 22 through the opening 41. The warm air in the air box 22 enters the two sides of the outer shell 10 through the two second exhaust pipes 23 respectively. Finally, the warm air is discharged through the two vents 29, thereby heating the interior of the car, so that the driver can be heated in time when parking in winter, thereby improving the driver's comfort.
[0044] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is limited by the appended claims and their equivalents.
