Technical Field

[0001] The utility model relates to the technical field of engineering machinery air conditioning, in particular to an air conditioning device for a crane. Background Art

[0002] Domestic construction machinery cab heating mainly includes engine hot water circulation heating and liquid fuel heater heating. The engine hot water circulation heating is generally used for the cab and the control room of twin-engine products, and the liquid fuel heater is used for the control room of single-engine products. The engine hot water circulation heating sucks the engine coolant through the engine water pump and directly pumps it to the heater core of the indoor unit, and then the fan exchanges the heat of the heater core to the cab.

[0003] Water-heating air conditioners have low heating efficiency in extremely cold regions. Since most crane operations are short-term and require flexible transfers, the operator needs to complete the operation in a short time, so the water-heating system cannot meet such requirements. This greatly reduces the efficiency of the crane. In addition, the air outlet of the air-conditioning system is a direct blow behind the seat, without a duct layout. This air outlet method causes uneven heat distribution in the control room, resulting in poor operator sensation. As users in extremely cold regions have increasingly stringent requirements for the comfort of operating construction machinery products, the current heating mode can no longer meet user needs.

[0004] Based on this, this patent invents a heating system integrated into the indoor unit of an air conditioner. On the basis of the original indoor unit of the air conditioner, an air heater is added to improve the heating efficiency to meet the usage requirements of users in extremely cold areas.

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.

[0027] In the description of the present invention, it should be understood that the terms "left side", "right side", "upper part", "lower part", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second", etc. do not indicate the importance of the components, and therefore cannot be understood as a limitation on the present invention. The specific dimensions used in this embodiment are only for illustrating the technical solution, and do not limit the scope of protection of the present invention.

[0028] like Figure 1-2 As shown, a crane air conditioning device includes an evaporator assembly 1 and an air heater 12. The evaporator assembly 1 is installed inside the control room body 2, and the evaporator assembly 1 is used for air circulation inside the control room body 2 to adjust the temperature inside the control room body 2.

[0029] The present application uses an air heater as a heating device of the air conditioning system, and integrates the air heater 12 with the evaporator assembly 1 inside the control room body 2 to overcome the respective problems of water-heating type air conditioners and air-heating type air conditioners;

[0030] As the mainstream heating form for construction machinery, water-heating air conditioners have the advantage of high comfort. However, due to the low water temperature in winter, it is necessary to wait for the water temperature to heat up to the set temperature before the heating effect can be achieved, thus reducing the working efficiency of the crane. Air-heating air conditioners can quickly heat in extremely cold weather, reducing the waiting time of crane operators. However, since air heating is used to directly heat the air and send it into the room, there are problems such as high heating temperature, dry climate, and poor user experience when using it.

[0031] The evaporator assembly 1 includes a shell 13, which is enclosed and embedded on the inner wall of the control room body 2. A return air port 14 is provided on the shell 13 for ventilating the inside of the evaporator assembly 1 and the control room body 2. An evaporator fan 11 is installed inside the shell 13. The air inlet of the evaporator fan 11 is connected to the air outlet of the air heater 12. The air is quickly heated by the rapid heating characteristics of the air heater 12, and its temperature is controlled. The heated warm air is continuously sent to the evaporator fan 11 for heating, thereby achieving the purpose of improving the heating efficiency and ensuring the user experience.

[0032] An evaporator air outlet assembly 3 is provided inside the control room body 2 , and the evaporator air outlet assembly 3 is connected to the air outlet of the evaporator fan 11 to deliver the air conditioning warm air into the control room body 2 .

[0033] Specifically, the minimum air volume of the evaporating fan 11 is greater than or equal to the air volume of the air heater 12 at the air outlet, so that all the hot air generated by the air heater 12 can enter the evaporating fan 11, thereby improving work efficiency and avoiding waste of heat energy.

[0034] In addition, the evaporator air outlet assembly 3 is set as a metal air supply duct 31, and the metal air supply duct 31 is evenly distributed in the control room body 2. A plurality of air supply ports 32 are opened on the metal air supply duct 31. The metal air supply duct 31 is evenly distributed on the inner wall of the control room body 2 in a serpentine shape. The plurality of air supply ports 32 evenly provide hot air in the control room body 2, thereby ensuring the uniformity of the temperature in the control room body 2 and improving the comfort of the operator.

[0035] The metal air supply duct 31 and the outer shell 13 are both provided with a heat insulation coating.

[0036] Specifically, temperature sensors 16 are installed on the inner wall of the control room body 2 at positions corresponding to the plurality of air outlets 32 , for sensing the temperature at the positions of the air outlets 32 .

[0037] Specifically, a controller 4 is also installed inside the control room body 2. The controller 4 is electrically connected to the temperature sensor 16 and is used to receive the signal of the temperature sensor 16. When the indoor temperature reaches the set temperature requirement, the controller 4 controls the operation of the evaporating fan 11 and the air heater 12 to achieve the control of the temperature and air volume of the air outlet 32 ​​of the heating system, thereby avoiding problems such as burns caused by excessive temperature of the air outlet 32.

[0038] Specifically, the control circuit of the air heater 12 is connected in parallel to the working circuit of the evaporator fan 11, and the operating status of the air heater 12 and the evaporator fan 11 are controlled. The air heater 12 can be turned on only when the evaporator fan 11 is running, or the evaporator fan 11 is automatically turned on while the air heater 12 is running, so as to avoid the hot air generated by the air heater 12 from being unable to be discharged in time, resulting in excessive temperature inside the evaporator assembly 1.

[0039] Specifically, an air conditioning filter element 15 is installed between the air inlet of the evaporating fan 11 and the air outlet of the air heater 12 and the return air outlet 14 for filtering the air to ensure the air quality in the control room body 2.

[0040] Specifically, the air heater 12 is disposed inside the housing 13 or outside the control room body 2 . Example

[0041] The air inlet of the air heater 12 is connected to the interior of the control room body 2 and is used to draw air from the control room body 2 for heating. Example

[0042] The air inlet of the air heater 12 extends to the outside of the control room body 2 through a pipeline, and is used to draw outdoor air for heating.

[0043] When the utility model is in use, the evaporating fan 11 and the air heater 12 are started at the same time, and the air is absorbed by the air heater 12. After the air is heated, the air is sent to the air inlet of the evaporating fan 11 to continue to heat up. During the process, the air is filtered and adsorbed by the air conditioning filter element 15. The evaporating fan 11 sends the heated air to various places in the control room body 2 through the metal air supply duct 31 and the air supply port 32, so as to realize temperature control. Comfortable operation can be achieved even in a cold environment, and the air in the control room body 2 is ventilated from the return air port 14.

[0044] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
