Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted evaporators, in particular to an evaporator with a filter element that is convenient for replacing. Background Art

[0002] The vehicle air conditioner is composed of a compressor, a condenser, a throttling element, an evaporator, a fan and necessary control components. It is an air conditioning system used to adjust the temperature and humidity in the vehicle and provide a comfortable environment for the passengers. When the compressor is working, the compressor inhales the low-temperature and low-pressure gaseous refrigerant from the evaporator. After compression, the temperature and pressure of the refrigerant increase and are sent to the condenser. Among them, the evaporator is a very important component of the four major refrigeration components. The low-temperature condensed liquid passes through the evaporator and exchanges heat with the outside air, gasifies and absorbs heat to achieve the cooling effect;

[0003] The filter element in the vehicle-mounted evaporator in the prior art is directly installed inside the evaporator outer shell. When it needs to be replaced, the evaporator must be opened for replacement. Opening the evaporator outer shell usually requires the use of external auxiliary tools. The steps are cumbersome and time-consuming. It is also easy to miss screws during installation, affecting the safe use of the evaporator. At the same time, most of the existing vehicle-mounted evaporators do not have good external protection capabilities and buffer protection capabilities. When encountering external impact force or pressure, the evaporator is prone to deformation or damage, affecting normal use and the safety of the device. Therefore, we need to upgrade and transform the existing technology to overcome its problems and shortcomings. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 As shown in Figure 5, the present embodiment provides an evaporator designed to facilitate filter element replacement, comprising a device body 1, the device body 1 comprising an outer shell 2 and a bottom plate 15, a connecting pipe 3 is arranged on the top of the outer shell 2, a side opening 4 is arranged at the front end of the outer shell 2, and jacks 5 are symmetrically arranged on the inner wall of the side opening 4, a sealing cover 6 is installed on the outer side of the side opening 4, and a movable groove 7 is opened in the sealing cover 6, a first spring 8 is arranged in the movable groove 7, and a movable rod 9 is connected to the outer side of the first spring 8, an installation frame 11 is inserted into the inside of the side opening 4, and a filter element 12 is placed in the installation frame 11, inner baffles 16 are arranged on both sides of the bottom plate 15, and the inner baffles 16 are fixed on both sides of the outer shell 2, and a plurality of groups of second springs 17 are arranged on the outer side of the inner baffle 16, and the outer side of the second spring 17 is connected to the outer baffle 18.

[0025] Preferably, a pressing block 10 is connected to the outer side of the movable rod 9 and the pressing block 10 is slidably located on the outer side of the sealing cover 6. The pressing block 10 is used to facilitate the movable rod 9 to move. The front end of the movable rod 9 extends to the outer side of the movable groove 7 and is plugged into the corresponding socket 5. The plugging of the movable rod 9 and the socket 5 facilitates the quick fixation of the sealing cover 6. Guide rods 13 are provided on both sides of the installation frame 11, and guide grooves 14 are provided on the inner wall of the side opening 4, and the guide grooves 14 correspond to the guide rods 13. The cooperation of the guide rods 13 and the guide grooves 14 facilitates the installation of the installation frame 11.

[0026] Preferably, two groups of rubber plates 19 are connected between the inner baffle plate 16 and the outer baffle plate 18, and the two groups of rubber plates 19 are respectively located at the upper and lower ends of the inner baffle plate 16 and the outer baffle plate 18. The rubber plates 19 are convenient for assisting the connection between the inner baffle plate 16 and the outer baffle plate 18. Limiting rings 20 are provided on the inner baffle plate 16 and the outer baffle plate 18. Both ends of the second spring 17 are located in the limiting rings 20. The limiting rings 20 facilitate the installation and position limitation of the second spring 17. The bottom plate 15 is located at the lower end of the outer shell 2 and a protective pad 21 is provided on the inner side. The protective pad 21 is in contact with the bottom surface of the outer shell 2. The protective pad 21 facilitates the protective connection between the outer shell 2 and the bottom plate 15.

[0027] The use principle and use process of the utility model are as follows: when using, first push the two groups of pressing blocks 10 inward, and the pressing blocks 10 drive the movable rod 9 to move inward of the movable groove 7, and the movable rod 9 squeezes the first spring 8 to contract. When the movable rods 9 on both sides are disengaged from the insertion holes 5, the sealing cover 6 is pulled outward and removed from the side opening 4. At this time, the installation frame 11 and the filter element 12 can be taken out from the inside of the outer shell 2, and the filter element 12 can be removed from the installation frame 11 for cleaning and replacement, and then the reverse operation can be performed to install it and re-fix the sealing cover 6. In the process of using the evaporator, it is installed and fixed through the bottom plate 15, and the bottom plate 15 is used to fix the bottom plate 15. A protective pad 21 is installed between the plate 15 and the outer shell 2 to facilitate friction and vibration protection of the upper end thereof. When the side of the device is bumped or subjected to external pressure, the outer baffle plate 18 contacts the external force-applying object, and the outer baffle plate 18 moves toward the side of the inner baffle plate 16 and squeezes the second spring 17. The second spring 17 contracts under the force, and the upper and lower groups of rubber plates 19 contract under the force at the same time, so that the pressure or impact force on the outer baffle plate 18 is elastically buffered and protected. After the force is applied, the second spring 17 elastically resets, and the rubber plate 19 slowly resets, thereby realizing the reset operation of the outer baffle plate 18, so that the outer baffle plate 18 can perform external protection work on the evaporator again.
