Description

Technical Field

[0001] The utility model relates to the field of household appliances, in particular to an air conditioner. Background Art

[0002] At present, the demand for household heating devices with simultaneous cooling devices is becoming more and more widely used. With the development of the times, people's requirements for environmental protection are getting higher and higher. Refrigeration devices begin to use new environmentally friendly refrigerants that are more friendly to the environment, such as those that can reduce ozone depletion and are beneficial to improving the global warming problem (such as R32 and 454b, etc.). However, the new environmentally friendly refrigerants have highly flammable properties. Once the refrigerant leaks, it will bring great potential safety hazards. In order to prevent it from leaking to the explosion concentration and causing safety accidents, generally, a gas detection sensor is set to monitor the refrigerant concentration in the use environment, so as to give an alarm in time when the refrigerant concentration in the use environment is too high, and avoid safety accidents such as combustion and explosion caused by refrigerant leakage. However, in the related art, when the sensor is repaired, the sensor is not easy to disassemble and assemble. Summary of the Utility Model

[0003] The utility model provides an air conditioner.

[0004] The air conditioner according to the embodiment of the present application includes a housing, a partition, a compressor, a bracket and a sensor. The partition isolates the housing to form a first space and a second space. The partition is provided with a through hole communicating the first space and the second space. The first space is used for arranging a gas pipe. The compressor is arranged in the second space. The bracket is detachably installed on the partition. The bracket passes through the through hole. The sensor is arranged on the bracket and located in the first space. The sensor is used for detecting the refrigerant concentration.

[0005] In this way, by arranging the sensor on the bracket and the bracket being detachably installed on the partition, when the sensor is repaired, the bracket and the sensor can be integrally detached from the partition from the second space, and then the sensor can be detached from the bracket, so that the sensor is convenient to disassemble and assemble, thereby improving the repair efficiency of the sensor and reducing the repair cost.

[0006] In some embodiments, the bracket is installed on the lower half of the partition.

[0007] Since the density of the refrigerant is greater than that of air, the refrigerant gathers downward under the action of gravity. Therefore, the bracket is installed on the lower half of the partition, so that the sensor can be located in the lower part of the first space, and the sensor can accurately detect the refrigerant concentration in the first space, preventing the refrigerant from leaking to the explosion concentration and causing safety accidents, thereby improving the safety of the air conditioner.

[0008] In some embodiments, the bracket includes a mounting member and a support plate connected to the mounting member. The mounting member is disposed on the surface of the partition facing the second space, the support plate is disposed in the first space, and the sensor is disposed on the support plate.

[0009] In this way, the mounting member is disposed on the surface of the partition facing the second space, facilitating the installation and removal of the bracket from the second space. The support plate is disposed in the first space, and the sensor is disposed on the support plate, enabling the sensor to detect the refrigerant density in the first space, preventing the refrigerant leakage from reaching the explosive concentration and causing safety accidents, thereby improving the safety of the air conditioner.

[0010] In some embodiments, the support plate is arranged horizontally, and the sensor is disposed on the lower surface of the support plate.

[0011] In this way, the sensor can be located at the lower part of the first space, and the sensor can accurately detect the refrigerant concentration in the first space, preventing the refrigerant leakage from reaching the explosive concentration and causing safety accidents, thereby improving the safety of the air conditioner.

[0012] In some embodiments, a wire is provided on the sensor. The wire passes through the mounting member and connects the sensor to the controller of the air conditioner.

[0013] In this way, the wire can transmit the refrigerant concentration detected by the sensor to the controller, and the controller controls the operation of the air conditioner according to the refrigerant concentration.

[0014] In some embodiments, the mounting member is provided with a through hole penetrating through the side surface and two surfaces in the thickness direction of the mounting member, and the wire passes through the through hole.

[0015] In this way, the through hole penetrates through the side surface of the mounting member, facilitating the wire to enter the through hole from the side surface of the mounting member. The wire passes through the through hole, enabling the wire to connect the sensor located in the first space and the controller located in the second space.

[0016] In some embodiments, the air conditioner includes a limiting member disposed in the through hole. The limiting member is provided with a limiting hole. The limiting hole is provided with an opening penetrating through the edge of the side surface of the limiting hole. Two limiting blocks are provided on the hole wall of the limiting hole. The limiting blocks can move relative to the limiting member, and the limiting blocks seal or open the opening.

[0017] In this way, by sealing or opening the opening with the limiting blocks, it is convenient for the wire to enter the limiting hole from the opening and makes the wire not easily fall off from the opening.

[0018] In some embodiments, the height of the through hole is lower than the height of the sensor.

[0019] In this way, it can prevent liquids such as rainwater from flowing along the wire from the through hole to the sensor, causing the sensor to malfunction and affecting the refrigerant leakage detection effect.

[0020] In some embodiments, a limiting strip is provided on the side of the mounting member facing away from the support plate. The wire is threaded through the limiting strip, and the limiting strip is used to space the wire from the mounting member.

[0021] In this way, the limiting strip can fix the wire, reduce the shaking of the wire, and keep a certain distance between the wire and the mounting member, preventing the wire from being worn when it shakes on the mounting member.

[0022] In some embodiments, ventilation openings are provided on the partition plate, and the through holes are located on one side of the ventilation openings.

[0023] In this way, the ventilation openings are used for air to flow between the first space and the second space. The through holes are located on one side of the ventilation openings, which can prevent the mounting member from blocking the ventilation openings and reduce the gas flow between the first space and the second space.

In addition, the present utility model provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0037] Please refer to Figures 1 - 5 , the air conditioner 100 according to the embodiment of the present application includes a housing 10, a partition 20, a compressor 30, a bracket 40, and a sensor 50. The partition 20 divides the housing 10 to form a first space 11 and a second space 12. The partition 20 is provided with a through hole 21 communicating the first space 11 and the second space 12. The first space 11 is used to arrange a gas pipe 13. The compressor 30 is arranged in the second space 12. The bracket 40 is detachably mounted on the partition 20. The bracket 40 passes through the through hole 21. The sensor 50 is arranged on the bracket 40 and is located in the first space 11. The sensor 50 is used to detect the refrigerant concentration.

[0038] In this way, by arranging the sensor 50 on the bracket 40 and detachably mounting the bracket 40 on the partition 20, when repairing the sensor 50, the bracket 40 and the sensor 50 can be integrally detached from the partition 20 from the second space 12, and then the sensor 50 can be detached from the bracket 40, making the disassembly and assembly of the sensor 50 convenient, thereby improving the repair efficiency of the sensor 50 and reducing the repair cost.

[0039] Specifically, the air conditioner 100 may be an integrated structure or a split structure. The housing 10 may be the outer shell of the machine where the air conditioner 100 communicates with the external environment. The partition 20 may be a square protective cover to separate the components in the first space 11 and the components in the second space 12. The through hole 21 penetrates the partition 20 along the wall thickness direction of the partition 20. The gas pipe 13 is used to convey gas to the first space 11. The first space 11 may accommodate an ignition device, and the ignition device may ignite the gas to heat the air flow. The second space 12 may accommodate the compressor 30, a blower, etc.

[0040] The compressor 30 cools by compressing the refrigerant. The bracket 40 and the partition 20 can be sheet metal parts, made of metal sheets such as steel, aluminum, and copper through cold working processes. The bracket 40 is used to fix the sensor 50 in the first space 11. The gas pipe 13 and the compressor 30 can be arranged on opposite sides of the first space 11. For example, the compressor 30 is arranged on the side close to the bracket 40, and the gas pipe 13 can communicate with the first space 11 through the side of the first space 11 facing away from the bracket 40.

[0041] When the air conditioner 100 needs to heat, the ignition device ignites the gas to complete the heating. However, when the refrigerant leaks, the ignition device may still ignite the leaked refrigerant, and the open flame generated during the combustion of the gas may also ignite the leaked refrigerant. The heat generated during the combustion of the gas will dissipate to the surroundings. If the heat at a certain place near the ignition device is too high, causing the temperature at that place to reach the ignition point of the refrigerant, it may cause the refrigerant to be ignited.

[0042] The sensor 50 can adopt a metal oxide semiconductor (MOS) sensor 50 or a non-dispersive infrared (NDIR) sensor 50. The working principle of the metal oxide semiconductor (MOS) sensor 50 is that based on the resistivity of some specific semiconductor materials changing as certain gases react on the semiconductor surface. Therefore, measuring the resistance of the metal oxide semiconductor can obtain the concentration of the refrigerant in the air in the first space 11. The non-dispersive infrared (NDIR) sensor 50 is based on the principle of spectral analysis. Different gas molecules have unique infrared absorption characteristics: by measuring the infrared absorption amount in a short transmission path, the non-dispersive infrared (NDIR) sensor 50 can determine the refrigerant concentration in the first space 11.

[0043] Please refer to Figure 2 , in some embodiments, the bracket 40 is installed on the lower half of the partition 20.

[0044] Since the density of the refrigerant is greater than the density of air, the refrigerant accumulates downward under the action of gravity. Therefore, the bracket 40 is installed on the lower half of the partition 20, so that the sensor 50 can be located in the lower part of the first space 11. The sensor 50 can accurately detect the refrigerant concentration in the first space 11, prevent the refrigerant leakage from reaching the explosive concentration and causing safety accidents, thereby improving the safety of the air conditioner 100.

[0045] Specifically, the bracket 40 being installed on the lower half of the partition 20 can be that the upper surface of the bracket 40 is between the lower surface of the partition 20 and 1 / 2 height. For example, the upper surface of the bracket 40 is at 1 / 3, 1 / 4, or 1 / 5 height of the partition 20.

[0046] Please refer to Figure 3 and Figure 4, in some embodiments, the bracket 40 includes a mounting member 41 and a support plate 42 connected to the mounting member 41. The mounting member 41 is disposed on the surface of the partition 20 facing the second space 12, the support plate 42 is disposed in the first space 11, and the sensor 50 is disposed on the support plate 42.

[0047] In this way, the mounting member 41 is disposed on the surface of the partition 20 facing the second space 12, facilitating the installation and removal of the bracket 40 from the second space 12. The support plate 42 is disposed in the first space 11, and the sensor 50 is disposed on the support plate 42, enabling the sensor 50 to detect the refrigerant density in the first space 11, preventing the refrigerant leakage from reaching the explosive concentration and causing safety accidents, thereby improving the safety of the air conditioner 100.

[0048] Specifically, the mounting member 41 and the support plate 42 may be in a plate-like structure. The mounting member 41 and the support plate 42 may be integrally formed or fixedly connected by fasteners such as bolts. An installation hole is formed by the inward extension of the surface of the partition 20 facing the second space 12, and fasteners such as bolts are screwed into the installation hole from the surface of the partition 20 facing the second space 12 to fix the mounting member 41 on the partition 20. The sensor 50 may be fixed on the support plate 42 by fasteners such as bolts.

[0049] Please refer to Figure 4 and Figure 5 , in some embodiments, the support plate 42 is arranged horizontally, and the sensor 50 is disposed on the lower surface of the support plate 42.

[0050] In this way, the sensor 50 can be located at the lower part of the first space 11, and the sensor 50 can accurately detect the refrigerant concentration in the first space 11, preventing the refrigerant leakage from reaching the explosive concentration and causing safety accidents, thereby improving the safety of the air conditioner 100.

[0051] Specifically, the thickness direction of the support plate 42 is the vertical direction. An installation hole is formed in the support plate 42 along the thickness direction, and fasteners such as bolts are screwed from the lower surface to the upper surface of the support plate 42 into the installation hole to fix the sensor 50 on the lower surface of the support plate 42.

[0052] Please refer to Figure 4 , in some embodiments, a wire 51 is provided on the sensor 50. The wire 51 passes through the mounting member 41 and connects the sensor 50 to the controller of the air conditioner 100.

[0053] In this way, the wire 51 can transmit the refrigerant concentration detected by the sensor 50 to the controller, and the controller controls the operation of the air conditioner 100 according to the refrigerant concentration.

[0054] In one embodiment, the controller may be connected to a communication module for communicating with an external terminal to send an alarm prompt to the external terminal. Specifically, the sensor 50 has a preset refrigerant concentration value. When the refrigerant concentration detected by the sensor 50 is greater than or equal to the preset refrigerant concentration, an alarm prompt is sent to the external terminal, and the heating signal sent to the ignition device is stopped. When the ignition device does not receive the heating signal, the ignition stops. In some embodiments, the communication module may be a wireless communication module such as a wifi module or Bluetooth.

[0055] Please refer to Figure 4 , in some embodiments, the mounting member 41 is provided with a through hole 43 that penetrates through the side surface and the two surfaces in the thickness direction of the mounting member 41, and the wire 51 is threaded through the through hole 43.

[0056] In this way, the through hole 43 penetrates through the side surface of the mounting member 41, facilitating the wire 51 to enter the through hole 43 from the side surface of the mounting member 41. The wire 51 is threaded through the through hole 43, enabling the wire 51 to connect the sensor 50 located in the first space 11 and the controller located in the second space 12.

[0057] Specifically, the through hole 43 may be formed by extending inward along the side surface of the mounting member 41, or may be formed by extending from one surface in the thickness direction of the mounting member 41 to the other surface. The shape of the through hole 43 may be a regular shape such as a circle, an ellipse, a rectangle, etc., or an irregular shape.

[0058] Please refer to Figure 4 , in some embodiments, the air conditioner 100 includes a limiting member 60 disposed in the through hole 43. The limiting member 60 is provided with a limiting hole 61. The limiting hole 61 is provided with an opening 62 that penetrates through the edge of the side surface of the limiting hole 61. Two limiting blocks 63 are provided on the hole wall of the limiting hole 61. The limiting blocks 63 can move relative to the limiting member 60, and the limiting blocks 63 seal or open the opening 62.

[0059] In this way, by sealing or opening the opening 62 with the limiting block 63, it is convenient for the wire 51 to enter the limiting hole 61 from the opening 62 and makes it difficult for the wire 51 to fall off from the opening 62.

[0060] Specifically, the limiting member 60 may be made of a flexible material such as rubber or plastic to prevent the wire 51 from being damaged due to friction with the limiting member 60 when the wire 51 shakes in the limiting hole 61. The limiting member 60 and the limiting blocks 63 may be integrally injection molded. When the two limiting members 60 move away from each other, the opening 62 is opened, and the wire 51 enters the limiting hole 61 from the opening 62; when the two limiting members 60 are in contact with each other or approach each other, the opening 62 is sealed to prevent the wire 51 from detaching from the limiting hole 61 through the opening 62.

[0061] Please refer to Figure 4, in some embodiments, the height of the via hole 43 is lower than the height of the sensor 50.

[0062] In this way, it is possible to prevent liquids such as rainwater from flowing from the via hole 43 along the wire 51 to the sensor 50, resulting in the failure of the sensor 50 and affecting the refrigerant leakage detection effect.

[0063] Specifically, the height of the via hole 43 being lower than the height of the sensor 50 can mean that the distance between the via hole 43 and the lower surface of the mounting member 41 is less than the distance between the sensor 50 and the lower surface of the mounting member 41. Further, it can mean that the height of the wire 51 at the via hole 43 is lower than the height of the connection between the wire 51 and the sensor 50.

[0064] Please refer to Figure 4 , in some embodiments, a limiting strip 44 is provided on the side of the mounting member 41 facing away from the support plate 42, and the wire 51 is threaded through the limiting strip 44, and the limiting strip 44 is used to space the wire 51 from the mounting member 41.

[0065] In this way, the limiting strip 44 can fix the wire 51, reduce the shaking of the wire 51, and keep a certain distance between the wire 51 and the mounting member 41 to prevent the wire 51 from being worn when shaking on the mounting member 41.

[0066] Specifically, the limiting strip 44 can be made of a metal material, the limiting strip 44 extends along the height direction of the mounting member 41, and the end of the limiting strip 44 away from the limiting hole 61 can be wound towards the end close to the limiting hole 61 to wind the wire 51 around the limiting strip 44, thereby fixing the wire 51. The limiting strip 44 can wind the wire 51 in a spiral shape along the axial direction of the wire 51.

[0067] Please refer to Figure 2 , in some embodiments, a ventilation opening 22 is provided on the partition 20, and the through hole 21 is located on one side of the ventilation opening 22.

[0068] In this way, the ventilation opening 22 is used for air to flow between the first space 11 and the second space 12. The through hole 21 being located on one side of the ventilation opening 22 can prevent the mounting member 41 from blocking the ventilation opening 22 and reduce the gas flow between the first space 11 and the second space 12.

[0069] Specifically, the ventilation opening 22 can penetrate the partition 20 along the thickness direction of the partition 20. The number of ventilation openings 22 can be multiple, such as three, four, five, six, etc. The shape of the ventilation opening 22 can be a regular shape such as a circle, a rectangle, an ellipse, etc., or an irregular shape. For example Figure 3As shown, the vent 22 is located on the left side of the partition 20, and the through hole 21 is located on the right side of the partition 20. In other embodiments, the vent 22 may be located on the right side of the partition 20, the through hole 21 may be located on the left side of the partition 20, or some of the vents 22 may be located on the left side of the partition 20, some of the vents 22 may be located on the right side of the partition 20, and the through hole 21 is located between the vents 22 on the left and right sides of the partition 20. When abnormal leakage occurs due to reasons such as damage to the refrigerant pipeline, the refrigerant can enter the first space 11 from the vent 22 and be ignited.
