[0030] Combination Figure 1 , Figure 2 and Figure 6As shown, the utility model provides a heating and cooling air conditioner for a forklift, comprising a heating and cooling air conditioner body 1 arranged at the rear of a forklift cab and an air conditioning interior component 2 arranged in the forklift cab, the air conditioning interior component 2 is integrally connected to the heating and cooling air conditioner body 1, the heating and cooling air conditioner body 1 comprises a shell assembly 11 and a refrigeration component and a heating component arranged inside the shell assembly 11; the refrigeration component comprises a compressor assembly 12, a condenser 13, a condensing fan 14, an evaporator component 15 and an evaporating fan 16, and the heating component comprises a PTC electric heating module 17; an air conditioning return air vent 111 is arranged in the middle part of the front plate of the shell assembly 11, the air conditioning return air vent 111 is connected to the interior of the forklift cab, and air conditioning outlets 112 are respectively arranged on the shell assembly 11 on both sides of the air conditioning return air vent 111; the PTC electric heating module 17 is arranged in an outlet air duct connected to the air conditioning outlet 112.

[0031] The technical solution of the utility model is a cooling and heating air conditioning system designed for a forklift, which aims to provide a comfortable environment in the cab. Specifically, it mainly includes a refrigeration system and a heating system. The refrigeration system is mainly composed of a compressor assembly 12, a condenser 13, an evaporator assembly 15, an evaporation fan 16 and a refrigeration control unit; the heating system is mainly composed of an electric heating module 17, an evaporation fan 16 and a heating control unit. The refrigeration system and the heating system are uniformly controlled by an integrated control module to achieve cooling and heating switching, temperature adjustment and air volume control.

[0032] The air conditioner body 1 is located at the rear of the forklift cab, and is composed of a housing assembly 11 and internal cooling and heating components. The cooling component mainly includes a compressor assembly 12, a condenser 13, a condensing fan 14, an evaporator assembly 15 and an evaporating fan 16, which work together to achieve the cooling function through a circulation system. The heating component includes a PTC electric heating module 17, which is used to provide heating function when needed to ensure that the driver's comfort can be maintained in a cold environment.

[0033] The middle part of the front plate of the housing assembly 11 is provided with an air conditioning return air vent 111, which is directly connected to the interior of the forklift cab to effectively circulate and regulate the indoor air. In addition, air conditioning outlets 112 are provided on both sides of the housing assembly 11 to re-inject regulated air into the cab. The PTC electric heating module 17 is cleverly placed in the outlet duct to ensure that the air transmitted through the outlet duct can quickly achieve heating or cooling effects, thereby meeting the needs of drivers in different environments.

[0034] This utility model not only improves the working comfort of the forklift driver, but also ensures the temperature stability and comfort in the cab under various weather conditions. The air conditioning system with integrated cooling and heating functions keeps the forklift warm in winter and cool in summer, thereby improving the driver's work efficiency and comfort.

[0035] like Figure 5 As shown, in the present utility model, the air conditioning interior component 2 includes an interior top 21 fixed to the top of the forklift cab, a return air outlet protection cover 22 covering the air conditioning return air outlet 111 and an air outlet protection cover 23 covering the air conditioning outlet 112.

[0036] The interior roof 21 is installed on the top of the forklift cab, which not only beautifies the interior design of the cab, but also provides additional heat insulation and sound insulation. It effectively isolates the main components of the heating and cooling air conditioning system to ensure that the driver is not directly affected by external temperature changes when operating the forklift. The main function of the return air vent protective cover 22 installed on the air conditioning return air vent 111 is to protect the air circulation system from the invasion of external debris and particulate matter, ensure the efficient operation of the air circulation, and try to avoid dust and other pollutants from entering the air conditioning system, thereby extending the service life of the system and reducing maintenance costs. The outlet protective cover 23 installed on the air conditioning outlet 112 is mainly to prevent external objects from directly contacting or damaging the PTC electric heating module 17 and the evaporating fan 16 inside the air conditioning outlet 112.

[0037] Furthermore, a control panel 24 for controlling the air conditioner and a lighting lamp 25 for providing lighting are provided on the interior ceiling 21. The forklift driver can select heating mode or cooling mode through the control panel. The integrated control module adjusts the working status of corresponding components according to the cooling or heating mode to achieve heating and cooling switching and temperature regulation.

[0038] In the utility model, the evaporator assembly 15 is arranged near the air-conditioning return air port 111, and the evaporator fan 16 is arranged near the air-conditioning outlet 112. The air in the cab enters the air-conditioning interior through the air-conditioning return air port 111 to exchange heat with the evaporator assembly 15, and then the evaporator fans 16 on both sides blow the cooled air out from the air-conditioning outlet 112, thereby optimizing the air flow path, reducing energy waste, and improving the energy efficiency ratio of the air-conditioning system.

[0039] Furthermore, combined with Figure 1-Figure 4As shown, an air conditioning heat dissipation exhaust port 113 is arranged on the top plate of the shell assembly 11, and an air conditioning heat dissipation air inlet 114 is arranged on the bottom plate of the shell assembly 11. The air conditioning heat dissipation exhaust port 113 is arranged above the condenser 13, and the air conditioning heat dissipation air inlet 114 is arranged below the condensing fan 14, which effectively optimizes the air flow path and ensures that the condenser 13 and the condensing fan 14 can work efficiently during the air flow, thereby improving the overall cooling efficiency and energy efficiency ratio.

[0040] In the utility model, a condensate collecting bin 115 is further provided on the bottom plate of the shell assembly 11 , and a drain port is provided at the bottom of the condensate collecting bin 115 , which can effectively collect and discharge the condensate generated during the condensation process.

[0041] In the present invention, a mounting bracket 116 is provided on the housing assembly 11, and the mounting bracket 116 is used to fix the air conditioner body 1 to the rear of the forklift cab. The mounting bracket 116 provided on the housing assembly 11 can firmly fix the air conditioner body 1 to the rear of the forklift cab. This not only ensures the safety and stability of the equipment, but also optimizes the space utilization, so that the equipment is closely integrated with the overall structure of the forklift, and reduces the risk of vibration and damage during movement.

[0042] In the utility model, the control panel 24 is provided with a wind speed adjustment knob, a temperature adjustment knob, an air conditioning status display light and an air conditioning function control switch, so that the driver can conveniently adjust the air conditioning system to meet different environmental requirements and personal comfort preferences, enhance the convenience of operation and the comfort of the driver, and improve work efficiency and the driver's job satisfaction.

[0043] Specifically, the air conditioning status display uses corresponding lights to represent whether the air conditioning is currently in ventilation, heating or cooling state; the air conditioning function control switch is set with three gears, namely heating, neutral (i.e. off), and cooling; the wind speed adjustment knob has three adjustable gears, and the wind speed increases clockwise; the temperature adjustment knob is set to stepless control, the temperature gradually decreases clockwise and gradually increases counterclockwise.

[0044] A second aspect of the utility model provides a forklift, wherein the forklift has the above-mentioned forklift cooling and heating air conditioner. By arranging the above-mentioned forklift cooling and heating air conditioner in the forklift, the comfort of the forklift can be improved.

[0045] In summary, the working principle of the utility model is as follows:

[0046] When the driver presses the cooling gear, the compressor assembly starts working, compressing the refrigerant into high-temperature and high-pressure gas, which becomes high-pressure liquid after dissipating heat through the condenser, and then enters the evaporator after throttling and reducing pressure through the expansion valve. After absorbing heat in the evaporator, it becomes low-temperature and low-pressure gas, and finally returns to the compressor to complete the cycle. The hot air in the cockpit enters the evaporator through the air inlet of the air conditioner to cool down, and is blown out from the air outlet by the evaporator fan. The condensed water produced by the evaporator drips into the collection bin and is discharged outside the cockpit through the drain port. The condensing fan efficiently dissipates heat from the condenser to ensure the normal operation of the compressor.

[0047] When the driver presses the heating gear, the PTC electric heating module starts working and generates heat, which is then sent into the forklift cab from the air-conditioning outlet through the evaporative fan. The temperature and wind speed knobs on the panel switch can adjust the working state of the heating element to maintain a suitable indoor temperature.

[0048] The utility model has the advantages of compact structure, low energy consumption and convenient maintenance, can meet the cooling and heating requirements of the forklift in different environments, and improves the comfort of the forklift and the working efficiency of the driver.

[0049] The preferred implementation modes of the present invention are described in detail above in combination with the accompanying drawings and embodiments, but the present invention is not limited thereto. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple modifications and combinations should also be regarded as the contents disclosed by the present invention and belong to the protection scope of the present invention.
