Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, and specifically provides a bed-mounted air conditioner. Background Art

[0002] Refrigerant is used to transfer heat energy and produce a refrigeration effect in refrigeration and air conditioning systems. Refrigerant is an intermediate substance in the refrigeration process. It first receives the coldness of the refrigerant and cools down, and then cools other cooled substances. We call this intermediate substance a refrigerant. Refrigerants include gas refrigerants, liquids and solid refrigerants. The refrigerants used in multi-split units are gas refrigerants, including R32, R410A, R22, etc., of which R32 is a flammable gas. It has a wide combustion range, so corresponding safety measures must be taken during handling, storage and use. When the concentration of R32 in the air exceeds a certain limit, a flammable mixture may be formed. Since R32 is a flammable gas, any gas leakage may cause a fire or explosion. When installing and maintaining the refrigeration system, the sealing of the system must be ensured. If the refrigerant leaks, the indoor or outdoor unit of the air conditioner needs to detect it within the specified time and alarm.

[0003] Refrigerant detectors are used in the detection process. Since the uncertainty of the leakage point and the fan opening state will affect the refrigerant concentration at different locations, the installation position of the refrigerant detector will affect the timeliness and accuracy of the measurement; in addition, the detector has a service life and needs to be replaced regularly. In the prior art, the refrigerant detector is installed in the electrical control box of the bed-mounted machine. The electrical control box is a pull-out design that can be pulled out for maintenance, which makes it convenient to disassemble and repair the refrigerant detector in the electrical control box. However, the placement of the refrigerant detector is not ideal for detecting whether the refrigerant is leaking.

[0004] Accordingly, the art needs a new technical solution to solve the above problems. Utility Model Content

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Furthermore, in order to more clearly demonstrate the core technical solution of the present utility model, the description of the known structure of the bed-mounted air conditioner is omitted in the following description. However, this omission is only for the convenience of description and does not mean that the bed-mounted air conditioner can be without these structures.

[0028] like Figure 1-2 As shown, the utility model proposes a bed-mounted air conditioner, comprising: a bed-mounted machine housing 1, the bed-mounted machine housing 1 has a side air inlet 2 on one side along the second direction; the first direction is the height direction of the bed-mounted machine housing 1, represented by Z in the figure, the second direction is the length direction of the bed-mounted machine housing 1, represented by X in the figure, the third direction is the width direction of the bed-mounted machine housing 1, not shown in the figure, and the air inlet direction of the side air inlet 2 is the second direction. Heat exchanger 3, the heat exchanger 3 is arranged in the bed-mounted machine housing 1; inlet and outlet liquid pipe 4, the inlet and outlet liquid pipe 4 is arranged in the bed-mounted machine housing 1, and is located on one side of the heat exchanger 3 along the second direction, and the inlet and outlet liquid pipe 4 is located between the side air inlet 2 and the heat exchanger 3; refrigerant detector 5, the refrigerant detector 5 is arranged on the heat exchanger 3.

[0029] The refrigerant detector 5 (refrigerant leak detector) is a device used to detect refrigerant leakage, and its principle mainly includes physical principle and chemical principle. The physical principle is to detect refrigerant leakage through the change of gas concentration caused by refrigerant leakage, while the chemical principle is to detect refrigerant leakage through chemical reaction between refrigerant and reagent. The refrigerant detector 5 can also be combined with auxiliary means such as sound / vibration and infrared for detection.

[0030] It should be pointed out that the present invention does not limit the type of refrigerant detector 5. Without deviating from the basic principles of the present invention, technical personnel in this field can adopt refrigerant detector 5 of any type and specification, as long as refrigerant detection can be performed, which does not deviate from the principles of the present invention and therefore will fall within the protection scope of the present invention.

[0031] In this embodiment, in order to solve the problem of unsatisfactory detection effect of the refrigerant detector in the bed-mounted air conditioner in the prior art, the refrigerant detector 5 is arranged behind the inlet and outlet liquid pipes 4 along the flow direction of the airflow. The inlet and outlet liquid pipes 4 are places where refrigerant leakage is relatively easy. After the refrigerant leaks, it will flow with the airflow; when the fan in the bed-mounted air conditioner is in a working state, the airflow enters the bed-mounted machine housing 1 from the side air inlet 2 along the second direction, flows through the inlet and outlet liquid pipes 4, and then flows to the heat exchanger 3. The refrigerant detector 5 is arranged on the heat exchanger 3, which can timely detect whether there is a refrigerant leakage, and timely issue an early warning, thereby improving the detection accuracy of the refrigerant detector 5; when the fan in the bed-mounted air conditioner is not in a working state, there is no air intake in the side air inlet 2, and the bed-mounted machine housing 1 is a closed space. If refrigerant leakage occurs in the inlet and outlet liquid pipes 4, the refrigerant detector 5 arranged on the heat exchanger 3 can also timely detect the refrigerant leakage and issue an early warning.

[0032] Further, if Figure 1-2 As shown, in order to improve the timeliness and accuracy of the detection of the refrigerant detector 5, the refrigerant detector 5 is located on the side of the heat exchanger 3 close to the inlet and outlet liquid pipes 4 along the second direction in this embodiment. The closer the refrigerant detector 5 is to the heat exchanger 3, the shorter the diffusion distance of the refrigerant from the inlet and outlet liquid pipes 4 to the refrigerant detector 5 after the refrigerant leaks, and the more timely the detection of the refrigerant detector 5 is; and the closer the refrigerant detector 5 is to the heat exchanger 3, the greater the refrigerant concentration when the refrigerant diffuses to the position of the refrigerant detector 5 after the refrigerant leaks, and the more accurate the detection effect of the refrigerant detector 5 will be, thereby avoiding the situation where the leakage is not detected due to the low refrigerant concentration at the position of the refrigerant detector 5, and avoiding fire or explosion caused by missed detection.

[0033] Further, if Figure 1-2 As shown, the bed-mounted air conditioner in this embodiment also includes a circuit board area 6, which is arranged in the bed-mounted machine housing 1, and the refrigerant detector 5 is electrically connected to the circuit board area 6. After the refrigerant detector 5 is connected to the circuit board area 6, the communication and control of the refrigerant detector 5 and the external device can be realized. For example, the refrigerant detector 5 can detect relevant parameters of the refrigerant, such as temperature, pressure, flow, etc. These parameters can be converted into electrical signals and transmitted to the external device through the circuit board area 6 to realize data monitoring and control; and, the external device can send a control signal to the refrigerant detector 5 through the circuit board area 6 to realize the control of the refrigerant detector 5, such as adjusting the detection accuracy of the refrigerant detector 5, setting the alarm threshold, etc.; and, the refrigerant detector 5 needs power to work normally, and the circuit board area 6 can supply power to the refrigerant detector 5; in addition, the circuit board 6 can provide a communication interface, so that the refrigerant detector 5 can exchange and communicate data with other devices, thereby realizing remote monitoring and data sharing.

[0034] Further, if Figure 1As shown, in this embodiment, in order to facilitate the electrical connection between the refrigerant detector 5 and the circuit board area 6, the circuit board area 6 and the inlet and outlet liquid pipes 4 are located on the same side of the heat exchanger 3 along the second direction, so that the line connection between the refrigerant detector 5 and the circuit board area 6 is simpler. The circuit board area 6 and the inlet and outlet liquid pipes 4 can be arranged in the first direction to reduce the width of the bed-mounted air conditioner in the third direction.

[0035] Further, if Figure 1-2 As shown, in this embodiment, the heat exchanger 3 includes a pipeline 7 and a pipeline fixing frame 8, and the pipeline fixing frame 8 is used to fix the pipeline 7. The stability and reliability of the pipeline 7 are ensured to prevent the pipeline 7 from loosening or displacement during the operation of the heat exchanger 3. At the same time, the pipeline fixing frame 8 can also improve the structural strength and load-bearing capacity of the heat exchanger 3 to ensure its long-term stable operation.

[0036] Furthermore, the refrigerant detector 5 is disposed on a pipe fixing frame 8 of the heat exchanger 3 , and the pipe fixing frame 8 can provide an installation position for the refrigerant detector 5 .

[0037] Further, if Figure 3-6 As shown, the bed-mounted air conditioner also includes: a panel frame 10 and an outer panel 11. The bed-mounted machine housing 1, the panel frame 10 and the outer panel 11 are arranged in sequence along a third direction. The heat exchanger 3 is arranged between the bed-mounted machine housing 1 and the panel frame 10. Components such as a fan are arranged between the heat exchanger 3 and the bed-mounted machine housing 1. Since the structure of the panel frame 10 and the outer panel 11 is relatively simple, they are generally disassembled starting from the outer panel 11 along the third direction. As long as the panel frame 10 and the outer panel 11 are removed, the heat exchanger 3 can be accessed.

[0038] Further, if Figure 5 As shown, in this embodiment, in order to ensure the accuracy and timeliness of refrigerant measurement while taking into account the removability of the refrigerant detector 5, the refrigerant detector 5 is arranged on the side of the pipe fixing frame 8 close to the panel frame 10. In this way, after removing the outer panel 11 and the panel frame 10 in turn, the refrigerant detector 5 on the side of the heat exchanger 3 close to the panel frame 10 can be removed.

[0039] Further, if Figure 1-2 As shown, the pipe fixing frame 8 has a connecting piece 9, which is located on one side of the pipe fixing frame 8 close to the panel frame 10, and the refrigerant detector 5 is arranged on the connecting piece 9. The position of the connecting piece 9 on the pipe fixing frame 8 can be moved along the first direction. In order to improve the detection accuracy and timeliness of the refrigerant detector 5, the connecting piece 9 can be moved to a position close to the inlet and outlet liquid pipes 4. Figure 1-2 As shown, the heat exchanger 3 is divided into three parts, namely, upper, middle and lower parts, along the first direction. The inlet and outlet liquid pipes 4 are located in the middle part of the heat exchanger 3 , and the connecting member 9 is also arranged in the middle position of the heat exchanger 3 .

[0040] The connecting member 9 has bolt holes, and the refrigerant detector 5 is set on the connecting member 9 by bolts. It should be pointed out that although the present embodiment specifies that the refrigerant detector 5 is set on the connecting member 9 by bolts, those skilled in the art may adopt other connection methods, such as snap-on or bonding, without departing from the basic principle of the present utility model, as long as the refrigerant detector 5 can be set on the connecting member 9. Of course, considering the detachability of the refrigerant detector 5, in the present embodiment, it is preferred that the refrigerant detector 5 and the connecting member 9 are connected by bolts.

[0041] In addition, it should be noted that although Figure 1 and Figure 2 The connector 9 shown in the figure is in the shape of an elongated strip, but this is not a limitation of the present invention. Without departing from the basic principle of the present invention, those skilled in the art may adopt a connector 9 of any shape and size, as long as the refrigerant detector 5 can be arranged thereon. This does not deviate from the principle of the present invention and therefore falls within the scope of protection of the present invention.

[0042] Those skilled in the art will appreciate that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present application and form different embodiments. For example, in the claims of the present application, any one of the claimed embodiments may be used in any combination.

[0043] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
