[0036] Unless otherwise stated, the term "plurality" means two or more.
[0037] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.
[0038] Combination Figure 1-7 As shown, the embodiment of the present disclosure provides a testing device for refrigeration equipment, including: a bottle body 100, a guide structure 200 and a support rod 300. The bottle body 100 has a bottle mouth 110, through which a solution is filled into the bottle body 100; the guide structure 200 is sleeved on the outside of the bottle mouth 110; one end of the support rod 300 passes through the guide structure 200 and extends into the solution inside the bottle body 100, and a temperature sensor 400 is arranged at the end of the support rod 300 extending into the bottle body 100; wherein the guide structure 200 can guide the support rod 300 so that the axis of the support rod 300 is parallel to the axis of the bottle mouth 110.
[0039] The test device for refrigeration equipment provided by the embodiment of the present disclosure is used. During the test, the bottle body 100 is filled with a solution to simulate the refrigeration load, and the temperature sensor 400 located in the solution inside the bottle body 100 is used to obtain temperature data. The purpose of the test is achieved by analyzing the temperature data. The temperature sensor 400 is supported by setting a support rod 300, and the temperature sensor 400 is extended into the solution inside the bottle body 100. The support rod 300 is guided by the guide structure 200 so that the support rod 300 and the axis of the bottle mouth 110 are always kept parallel. The temperature sensor 400 is not easily displaced when the bottle body 100 is moved or the placement state is changed, which reduces the risk of the temperature sensor 400 touching the inner wall of the bottle body 100, increases the stability of the temperature sensor 400 inside the bottle body 100, and improves the accuracy of the test data.
[0040] Optionally, the bottle body 100 is made of a transparent glass material. In this way, the bottle body 100 is made of a transparent material, and the user can observe the amount of solution filled in the bottle body 100 through the bottle body 100 during the test, and can also observe the position of the temperature sensor 400 and whether the temperature sensor 400 is tilted, and adjust the position of the temperature sensor 400 in time.
[0041] Optionally, the solution filled in the bottle 100 is a diluent of propylene glycol. In this way, propylene glycol is an antifreeze agent, and by diluting propylene glycol to form a solution and filling it into the bottle 100, the test device for refrigeration equipment can better simulate the refrigeration load, thereby improving the accuracy of the test.
[0042] Specifically, the dilution ratio of the solution is four parts propylene glycol to one part water. In this way, by diluting propylene glycol with this ratio, it is possible to avoid the filled solution having too high a concentration and poor heat exchange performance, which makes it difficult to simulate the heat exchange scenario of the refrigeration load, so that the filled solution can better simulate the refrigeration scenario of the refrigeration load and improve the accuracy of the test.
[0043] Optionally, the volume inside the bottle body 100 is 240ml or 1200ml. In this way, by setting different volumes of the bottle body 100, the test device for refrigeration equipment can be adapted to the test of different positions of the refrigeration equipment, better simulate refrigeration loads of different sizes, and improve the application range of the test device for refrigeration equipment.
[0044] It can be understood that the refrigeration load may be a food load.
[0045] Taking the use of the test device for refrigeration equipment to test the refrigeration performance of the refrigerator as an example, a test device for refrigeration equipment with a bottle body of 100 and a volume of 1200ml is placed in the cold storage compartment, and a test device for refrigeration equipment with a bottle body of 100 and a volume of 240ml is placed on the door shelf. Since the refrigeration loads placed in the cold storage compartment and the door shelf are different in size, the refrigeration load placed inside the cold storage compartment is usually larger, and the refrigeration load placed on the door shelf is usually relatively small, so test devices for refrigeration equipment with different volumes are placed separately for testing. Multiple test devices for refrigeration equipment are set in the upper, middle and lower areas of the cold storage compartment, and multiple test devices for refrigeration equipment are also set in the upper, middle and lower areas of the door shelf to simultaneously obtain the temperature changes per unit time at different positions inside the refrigerator, and achieve the purpose of testing by analyzing the data.
[0046] Optionally, the temperature sensor 400 is a thermocouple.
[0047] Optionally, the portion of the support rod 300 located in the guide structure 200 is slidably connected to the guide structure 200, so that the support rod 300 can slide along the axis of the bottle mouth 110. In this way, the support rod 300 can slide to different positions along the guide structure 200, thereby adjusting the position of the temperature sensor 400 inside the bottle body 100, and obtaining the temperature changes at different positions inside the bottle body 100 through the temperature sensor 400, so as to meet the diversified testing requirements. During the sliding process, the support rod 300 can always remain parallel to the axis of the bottle mouth 110, and the temperature sensor 400 is not easy to be displaced when the bottle body 100 moves or the placement state changes, thereby reducing the risk of the temperature sensor 400 touching the inner wall of the bottle body 100.
[0048] For example, when testing the performance of the refrigeration equipment, the temperature change inside the bottle body 100 is obtained through the temperature sensor 400 to reflect the temperature change of the refrigeration load in the refrigeration equipment. Due to the diversity of test requirements, it is necessary to obtain the temperature change at different positions in the refrigeration load. Therefore, according to the test requirements, the support rod 300 is driven to slide upward along the axis of the bottle mouth 110 to adjust the position of the temperature sensor 400 at the end of the support rod 300.
[0049] Alternatively, if Figure 3As shown, the support rod 300 is a hollow structure, and one end of the temperature measuring line 410 is passed along the end of the support rod 300 located outside the bottle body 100 to the end of the support rod 300 located inside the bottle body 100, and is connected to the temperature sensor 400. In this way, since the temperature sensor 400 is located at the end of the support rod 300 extending into the bottle body 100, the data detected by the temperature sensor 400 needs to be transmitted to the outside, so the temperature measuring line 410 is connected to the temperature sensor 400, and the detected temperature data is transmitted to the outside through the temperature measuring line 410. In order to ensure the laying of the temperature measuring line 410, the support rod 300 is set to a hollow structure, and the temperature measuring line 410 is laid along the inside of the support rod 300. One end of the temperature measuring line 410 is connected to the temperature sensor 400, and the other end passes through the end of the support rod 300 and is connected to the external receiving module.
[0050] Optionally, both ends of the support rod 300 have openings, the temperature sensor 400 is disposed at one end of the support rod 300, and the opening of the end is closed, and one end of the temperature measuring line 410 penetrates along the opening of the other end of the support rod 300 to the temperature sensor 400 and is connected thereto. In this way, the solution in the bottle 100 can be prevented from entering the support rod 300, thereby improving the accuracy of the test.
[0051] Optionally, a storage box 310 is provided at one end of the support rod 300 located outside the bottle body 100, and a sensor plug 420 is connected to one end of the temperature measuring line 410 located outside the support rod 300, and the sensor plug 420 and the temperature measuring line 410 located outside the support rod 300 are movably provided in the storage box 310. In this way, the temperature sensor 400 is connected to the sensor plug 420 through the temperature measuring line 410, and the sensor plug 420 is plugged into the receiving module for data transmission. When the test device for refrigeration equipment is in a non-testing state, the temperature measuring line 410 and the sensor plug 420 located outside the support rod 300 cannot be placed, which will cause the temperature measuring line 410 to be entangled with the sensor plug 420, so the storage box 310 is provided at one end of the support rod 300 located outside the bottle body 100, and the storage box 310 is used to store the temperature measuring line 410 and the sensor plug 420 located outside the support rod 300.
[0052] Optionally, a connection section is provided at one end of the storage box 310, and the storage box 310 is connected to the support rod 300 through the connection section, and a cover plate is movably connected to the other end of the storage box 310. In this way, one end of the temperature measuring line 410 passes through the support rod 300 along the inside of the storage box 310, and then passes through the temperature sensor 400 to connect with it. When the temperature measuring line 410 and the sensor plug 420 are in a non-testing state, the temperature measuring line 410 and the sensor plug 420 located outside the support rod 300 can be stored in the storage box 310, and the storage box 310 is closed by the cover plate to store the temperature measuring line 410 and the sensor plug 420.
[0053] Alternatively, if Figure 4 and Figure 5 As shown, the guide structure 200 includes: a guide cylinder 210, a first limiting plate 220 and a second limiting plate 230. The lower end of the guide cylinder 210 is sleeved on the outside of the bottle mouth 110; the first limiting plate 220 is arranged on the inner side of the guide cylinder 210, and the first limiting hole 221 is arranged in the center area of the first limiting plate 220; the second limiting plate 230 is arranged on the inner side of the guide cylinder 210 and is located between the first limiting plate 220 and the bottle mouth 110, and the second limiting hole 231 is arranged in the center area of the second limiting plate 230; wherein, one end of the support rod 300 passes through the first limiting hole 221, the second limiting hole 231 and the bottle mouth 110 in sequence and extends into the interior of the bottle body 100. In this way, the guide cylinder 210 is sleeved on the outer side of the bottle mouth 110 so that the axis of the guide cylinder 210 coincides with the axis of the bottle mouth 110, and the first limiting plate 220 and the second limiting plate 230 are arranged inside the guide cylinder 210, and the support rod 300 sequentially passes through the first limiting hole 221, the second limiting hole 231 and the bottle mouth 110 and extends into the bottle body 100. Since the first limiting hole 221 is located at the center area of the first limiting plate 220, and the second limiting hole 231 is located at the center area of the second limiting plate 230, the axis of the support rod 300 coincides with the axis of the guide cylinder 210 under the action of the first limiting hole 221 and the second limiting hole 231, so that the axis of the support rod 300 coincides with the axis of the bottle mouth 110, so as to guide the support rod 300 stably and prevent the temperature sensor 400 at the end of the support rod 300 from touching the inner wall of the bottle body 100.
[0054] Optionally, the outer wall of the support rod 300 is slidably connected to the inner wall of the first limiting hole 221 and the second limiting hole 231. In this way, the support rod 300 can slide upward along the axial direction of the guide cylinder 210, thereby adjusting the position of the temperature sensor 400 at the end of the support rod 300 to meet various testing requirements. Under the guidance of the first limiting hole 221 and the second limiting hole 231, the sliding of the support rod 300 can be made more stable, reducing the risk of the temperature sensor 400 at the end of the support rod 300 touching the inner wall of the bottle body 100.
[0055] Optionally, the first limiting plate 220 and the second limiting plate 230 are both made of plastic material. In this way, the first limiting plate 220 and the second limiting plate 230 are both elastic, and the outer wall of the support rod 300 can generate a certain friction damping with the inner wall of the first limiting hole 221 and the second limiting hole 231, thereby improving the stability of the support rod 300.
[0056] Optionally, the guide structure 200 further includes: a sealing plug 240. The sealing plug 240 is arranged on the inner side of the guide cylinder 210 and is located between the second limiting plate 230 and the bottle mouth 110. The axial region of the sealing plug 240 is provided with a through hole 241; wherein, when the guide cylinder 210 is sleeved on the outer side of the bottle mouth 110, the end surface of the sealing plug 240 facing the bottle mouth 110 abuts against the edge of the bottle mouth 110, and the support rod 300 is arranged through the through hole 241, and the outer wall of the support rod 300 located inside the through hole 241 abuts against the inner wall of the through hole 241. In this way, since the bottle body 100 is filled with a solution, the bottle body 100 needs to meet different placement states during the test, such as vertical placement or horizontal placement. In order to prevent the solution inside the bottle body 100 from leaking through the bottle mouth 110, a sealing plug 240 is provided inside the guide cylinder 210. One end surface of the sealing plug 240 abuts against the edge of the bottle mouth 110 to form a seal, thereby improving the sealing effect at the bottle mouth 110. A through hole 241 is provided in the axial region of the sealing plug 240 for the support rod 300 to pass through. The support rod 300 is further guided by the cooperation of the sealing plug 240 with the first limiting plate 220 and the second limiting plate 230, thereby making the support rod 300 more stable. The outer wall of the support rod 300 located inside the through hole 241 abuts against the inner wall of the through hole 241, so that the support rod 300 is used to block the through hole 241, thereby preventing the solution inside the bottle body 100 from flowing out from the through hole 241.
[0057] Optionally, the sealing plug 240 is made of rubber material, so that the sealing effect of the sealing plug 240 can be improved, and the sealing plug 240 can be deformed, and when the support rod 300 passes through, the inner wall of the through hole 241 is used to cover the support rod 300, further improving the sealing effect at the through hole 241.
[0058] Illustratively, along the axial direction of the guide cylinder 210, the first limiting disk 220, the second limiting disk 230 and the sealing plug 240 are arranged in sequence, and the end of the support rod 300 passes through the first limiting disk 220, the second limiting disk 230 and the sealing plug 240 in sequence and extends into the bottle body 100. Since the first limiting disk 220, the second limiting disk 230 and the sealing plug 240 are all located on the inner side of the guide cylinder 210, and the first limiting hole 221, the second limiting hole 231 and the through hole 241 are all located in the center area of the circle, the support rod 300 is guided by the cooperation of the first limiting disk 220, the second limiting disk 230 and the sealing plug 240.
[0059] Optionally, a first through groove 222 extending along the outer circumference of the first limiting hole 221 to the outer circumference of the first limiting plate 220 is provided on the inner side of the first limiting plate 220; a second through groove 232 extending along the outer circumference of the second limiting hole 231 to the outer circumference of the second limiting plate 230 is provided on the inner side of the second limiting plate 230. In this way, the provision of the first through groove 222 and the second through groove 232 makes the elastic margin of the first limiting plate 220 and the second limiting plate 230 larger, avoiding the first limiting hole 221 and the second limiting hole 231 being too tight so that the support rod 300 cannot pass through, and facilitating the sliding adjustment of the support rod 300 while ensuring the stability of the support rod 300.
[0060] Alternatively, if Figure 6 As shown, the test device for refrigeration equipment also includes: a driving mechanism 500. The driving mechanism 500 is arranged on the side of the guide structure 200 facing away from the bottle body 100, and the driving mechanism 500 is movably connected to the support rod 300, and is used to drive the support rod 300 to slide upward along the axis of the bottle mouth 110. In this way, by setting the driving mechanism 500 to drive the support rod 300 to slide and retract, if it is necessary to adjust the position of the temperature sensor 400 in the bottle body 100 to test the temperature at different positions inside the bottle body 100 during the test process, there is no need to adjust it manually, and the driving mechanism 500 can be used to drive the support rod 300 to slide, thereby improving the efficiency of the test. Moreover, the driving mechanism 500 has a higher accuracy in driving the support rod 300 to slide, and the temperature sensor 400 can be accurately adjusted to the target position.
[0061] Optionally, the driving mechanism 500 includes: a mounting tube 510, a first driving part 520 and a second driving part 530. The mounting tube 510 is arranged on the side of the guide structure 200 facing away from the bottle body 100, and one end of the support rod 300 passes through the mounting tube 510 and the guide structure 200 in sequence and extends into the bottle body 100; the first driving part 520 is arranged on the inner side of the mounting tube 510 and is located on one side of the support rod 300 in the radial direction, and the first driving part 520 is movably connected to one side wall of the support rod 300 in the radial direction; the second driving part 530 is arranged on the inner side of the mounting tube 510 and is located on the other side of the support rod 300 in the radial direction, and the second driving part 530 is movably connected to the other side wall of the support rod 300 in the radial direction. In this way, the support rod 300 is driven by the cooperation of the first driving part 520 and the second driving part 530 provided inside the mounting tube 510. Since the first driving part 520 and the second driving part 530 are symmetrically arranged on both sides of the support rod 300, the first driving part 520 is movably connected to one side wall of the support rod 300, and the second driving part 530 is movably connected to the other side of the support rod 300. The cooperation of the first driving part 520 and the second driving part 530 forms an extrusion-type driving effect on the support rod 300, thereby improving the driving stability of the support rod 300. Moreover, the cooperation of the first driving part 520 and the second driving part 530 can further guide the support rod 300, so that the support rod 300 can slide more stably along the axis direction of the bottle mouth 110.
[0062] Optionally, the mounting cylinder 510 is disposed on the side of the guide cylinder 210 facing away from the bottle body 100, and the axis of the mounting cylinder 510 coincides with the axis of the guide cylinder 210. In this way, the first driving part 520 and the second driving part 530 inside the mounting cylinder 510 can drive the support rod 300 to slide and retract along the axis direction of the guide cylinder 210, thereby improving the sliding stability of the support rod 300.
[0063] Optionally, the first driving part 520 includes a first driving disk, the center of which is connected to a driving motor, and the second driving part 530 includes a second driving disk, the center of which is also connected to a driving motor; the first driving disk and the second driving disk are symmetrically arranged on both sides of the support rod 300, the outer peripheral wall of the first driving disk is slidably connected to one side wall of the support rod 300, and the outer peripheral wall of the second driving disk is slidably connected to the other side wall of the support rod 300. In this way, the first driving disk and the second driving disk rotate in opposite directions or in reverse directions to form an extrusion driving effect on the support rod 300, thereby improving the driving stability of the support rod 300.
[0064] Optionally, the first driving part 520 includes two first driving disks, and the second driving part 530 includes two second driving disks, and the two first driving disks and the two second driving disks are arranged along the length direction of the support rod 300, one of the two first driving disks and one of the two second driving disks are symmetrically arranged on both sides of the support rod 300, and the other of the two first driving disks and the other of the two second driving disks are symmetrically arranged on both sides of the support rod 300. In this way, the sliding connection area between the first driving part 520 and the second driving part 530 and the support rod 300 is increased, thereby further improving the driving stability of the support rod 300.
[0065] Alternatively, if Figure 7 As shown, the test device for refrigeration equipment also includes: a controller 600. The controller 600 is used to receive a test instruction, and control the drive mechanism 500 to drive the support rod 300 to slide to a target position according to the test instruction. In this way, when performing a test, the controller 600 can receive a test instruction issued by a user, and then control the drive mechanism 500 to drive the support rod 300 to slide to a target position according to the test instruction, so as to meet various test requirements and improve the accuracy of the test.
[0066] Optionally, the test device for refrigeration equipment further includes: an instruction input module 610 . The controller 600 can receive a test instruction sent by the instruction input module 610 .
[0067] Optionally, the instruction input module 610 is a microphone or a touch screen. In this way, when the position of the temperature sensor 400 needs to be adjusted during the test, the tester can input voice instruction information through the microphone, or input instruction information through the touch screen, and the controller 600 receives the instruction information input by the microphone or the touch screen, parses the test instruction, and controls the support rod 300 to slide to the target position corresponding to the test instruction according to the test instruction.
[0068] It can be understood that the support rod 300 slides to different target positions corresponding to different test instructions, and the multiple target positions have a one-to-one correspondence with the test instructions. The corresponding relationship is pre-stored in the database of the controller 600. When the controller 600 receives one of the test instructions, the corresponding target position can be determined. The initial position of the support rod 300 during the test is the same, and the multiple target positions of the support rod 300 are all set relative to the initial position.
[0069] Taking the instruction input module 610 as a microphone as an example, the tester says the voice information of "adjust the support rod 300 to the first target position", the microphone collects the voice information and sends it to the controller 600, the controller 600 obtains the voice information and parses the corresponding test instruction to control the support rod 300 to adjust to the first target position, and then reacts to control the driving structure to drive the support rod 300 to slide to the first position.
