TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, in particular to an indoor unit of an air conditioner and the air conditioner. BACKGROUND

[0002] When the air conditioner uses a refrigerant such as R32 that has flammable and explosive characteristics, the safety of use is particularly important. Relevant regulations stipulate that if the refrigerant leaks, it needs to be detected within a specified time.

[0003] In the related art, an indoor unit is disclosed, which has a frame body, an upper space inside the frame body and configured with an indoor heat exchanger, a lower space inside the frame body and arranged below the upper space, an indoor air supply fan arranged in the lower space, a fan shell arranged in the lower space for covering the indoor air supply fan, and forming a blowing opening and a suction opening, a refrigerant detection unit, the blowing opening is communicated with the upper space, and the refrigerant detection unit is arranged in the lower space.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0005] The air supply fan is arranged in the lower space, and a volute is further arranged outside the air supply fan, which makes the lower space relatively compact. On the one hand, it leads to great difficulty in installing the refrigerant detection unit, and on the other hand, in the case that the air supply fan is closed, the air flow in the lower space is poor due to the compactness of the lower space, and it is not easy to discover the refrigerant leakage in time.

[0006] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present application, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art. Content of the utility model

[0007] In order to have a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not a general review, nor is it intended to determine key / important components or delineate the scope of protection of these embodiments, but as a prelude to the detailed description below.

[0008] The embodiments of the present disclosure provide an indoor unit of an air conditioner and the air conditioner, to solve the problems of great difficulty in installing the refrigerant detection unit and not easy to discover the refrigerant leakage in time in the related art.

[0009] According to a first aspect of the embodiments of the present utility model, an indoor unit of an air conditioner is provided, comprising: a shell body, defining an air duct, the air duct comprising a first air duct section and a second air duct section in communication; a fan arranged in the first air duct section; an evaporator arranged in the second air duct section; and a refrigerant leakage detector arranged in the second air duct section.

[0010] The second air duct section is located in the area where air flows in the indoor unit, and therefore, the refrigerant leakage detector is arranged in the second air duct section, and refrigerant leakage can be detected within a specified time in both cases of when the fan is on and when the fan is off.

[0011] Furthermore, compared with the first air duct section, the second air duct section is provided with an evaporator, and the evaporator comprises a plate-shaped structure and occupies a small space, and therefore, the space in the second air duct section is more spacious than the space in the first air duct section, so that the refrigerant leakage detector is easy to install, and the air flow in the second air duct section is better than the air flow in the first air duct section, so that in the case where the fan is off, the refrigerant can spread to the second air duct section more quickly, and refrigerant leakage can be detected more timely. Furthermore, refrigerant leakage is prone to occur at the welding points and the curved portions of the pipeline of the evaporator, and the refrigerant leakage detector arranged in the second air duct section can also detect refrigerant leakage more quickly.

[0012] Optionally, the housing comprises: a first side plate arranged at one end of the length direction of the evaporator; a second side plate arranged at the other end of the length direction of the evaporator; and a mounting member connected between the first side plate and the second side plate, the mounting member, the first side plate and the second side plate jointly define the second air duct section, and the refrigerant leakage detector is arranged on the mounting member.

[0013] The mounting member is arranged opposite to the plane where the length and the width of the evaporator are located, and the refrigerant leakage detector is arranged on the mounting member, so that the refrigerant leakage detector is also arranged opposite to the plane where the length and the width of the evaporator are located, and thus when refrigerant leakage occurs at the evaporator, the refrigerant leakage detector can detect the refrigerant leakage more quickly.

[0014] Furthermore, the space at the mounting member is relatively spacious, and the refrigerant leakage detector is arranged on the mounting member, which can reduce the installation difficulty on one hand, and on the other hand, the air flows more smoothly at the mounting member, so that the sensitivity of the refrigerant leakage detector can be further improved.

[0015] Optionally, the mounting member is arranged above or below the evaporator.

[0016] Since the density of the refrigerant is greater than the density of air, the leaked refrigerant flows downward, and when the mounting member is arranged below the evaporator, more refrigerant can flow to the mounting member, so that the detection sensitivity of the refrigerant leakage detector can be further improved.

[0017] When the mounting member is arranged above the evaporator, due to the factors such as that the mounting member is close to the evaporator and the space between the mounting member and the evaporator is relatively spacious, the refrigerant leakage detector can also quickly detect the refrigerant leakage.

[0018] Optionally, the mounting member is a metal member.

[0019] The mounting piece is made of metal, which has high structural strength and strong resistance to plastic deformation, thereby improving the load capacity and durability of the mounting piece, and increasing the reliability and safety of the mounting piece, so that the mounting piece can meet the requirements of the refrigerant leakage detector on the mounting strength.

[0020] Optionally, the mounting piece is provided with a reinforcing rib.

[0021] The reinforcing rib can improve the load capacity and stability of the mounting piece, and enhance the structural strength of the mounting piece, so that the mounting piece can stably support the refrigerant leakage detector.

[0022] Optionally, the refrigerant leakage detector is arranged on the evaporator.

[0023] In this way, the distance between the refrigerant leakage detector and the evaporator can be reduced, so that the refrigerant leakage detector can detect refrigerant leakage in time, and the safety of the air conditioner is improved.

[0024] Optionally, the refrigerant leakage detector is arranged at the middle of the length direction of the evaporator.

[0025] When the refrigerant leakage detector is arranged on the evaporator, the refrigerant leakage detector is arranged at the middle of the length direction of the evaporator; when the refrigerant leakage detector is arranged on the mounting piece, the refrigerant leakage detector is arranged on the mounting piece at the middle of the length direction of the evaporator, i.e. at the middle of the length direction of the mounting piece. In this way, when refrigerant leakage occurs at each position of the length direction of the evaporator, the refrigerant can quickly spread to the refrigerant leakage detector, so that the detection of the refrigerant leakage detector is more accurate, and the detection sensitivity is improved.

[0026] Optionally, the refrigerant leakage detector is arranged at the middle of the width direction of the evaporator.

[0027] When the refrigerant leakage detector is arranged on the evaporator, the refrigerant leakage detector is arranged at the middle of the width direction of the evaporator; when the refrigerant leakage detector is arranged on the mounting piece, the refrigerant leakage detector is arranged on the mounting piece at the middle of the width direction of the evaporator, i.e. at the middle of the width direction of the mounting piece. In this way, when refrigerant leakage occurs at each position of the width direction of the evaporator, the refrigerant can quickly spread to the refrigerant leakage detector, so that the detection of the refrigerant leakage detector is more accurate, and the detection sensitivity is improved.

[0028] Optionally, the evaporator is arranged obliquely in the second air duct section.

[0029] The oblique arrangement of the evaporator can reduce the thickness of the indoor unit, and form a thinner indoor unit.

[0030] According to a second aspect of the embodiments of the present application, an air conditioner is provided, which comprises the indoor unit of the air conditioner according to any one of the above embodiments.

[0031] The air conditioner provided by the second aspect of the embodiment of the utility model has all the beneficial effects of the indoor unit of the air conditioner as described in any one of the above embodiments, and thus will not be described here again.

DETAILED DESCRIPTION

[0041] In order to enable a more detailed understanding of the features and technical content of the embodiments of the present disclosure, the implementation of the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings, which are for reference only and do not limit the embodiments of the present disclosure. In the following technical description, in order to facilitate explanation, a plurality of details are provided to provide a sufficient understanding of the disclosed embodiments. However, one or more embodiments can still be implemented without these details. In other cases, well-known structures and devices can be simplified to facilitate the drawings.

[0045] Unless otherwise specified, the term "a plurality of" means two or more.

[0046] In the embodiments of the present disclosure, the character " / " represents an "or" relationship between the objects before and after it. For example, A / B represents: A or B.

[0047] The term "and / or" is a description of the association between objects, which means that there can be three relationships. For example, A and / or B, which means: A, or B, or, A and B, the three relationships.

[0048] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0049] In combination Figures 1-5 As shown in the accompanying drawings, the indoor unit of the air conditioner provided by the embodiments of the present disclosure comprises a shell 1, a fan 30, an evaporator 20, and a refrigerant leakage detector 50.

[0050] As Figure 1 and Figure 2 shown, the shell 1 defines an air duct, which comprises a first air duct section 12 and a second air duct section 11 connected in communication; the fan 30 is arranged in the first air duct section 12; the evaporator 20 is arranged in the second air duct section 11; and the refrigerant leakage detector 50 is arranged in the second air duct section 11.

[0051] Refrigerant is a key medium in a refrigeration system, and leakage will cause the refrigeration effect to be poor. The refrigerant leakage detector 50 helps to maintain the refrigeration effect of the refrigeration system, wherein the arrangement of the refrigerant leakage detector 50 can ensure the safe operation of the air conditioner and improve the reliability.

[0052] The shell 1 is further provided with an air inlet 1231 and an air outlet, and the air duct is in communication with the air inlet 1231 and the air outlet. As Figure 2 shown, the air inlet 1231, the first air duct section 12, the second air duct section 11, and the air outlet are arranged in sequence, or the air inlet 1231, the second air duct section 11, the first air duct section 12, and the air outlet are arranged in sequence.

[0053] The fan 30 is arranged in the first air duct section 12, and under the action of the fan 30, air enters from the air inlet 1231, passes through the evaporator 20, and then flows out through the air outlet, thereby realizing the normal work of the air conditioner.

[0054] The fan 30 is arranged in the first air duct section 12, and under the action of the fan 30, air enters from the air inlet 1231, passes through the evaporator 20, and then flows out through the air outlet, thereby realizing the normal work of the air conditioner.

[0055] The second air duct section 11 is located in the region of air flow circulation in the indoor unit, and therefore, the refrigerant leakage detector 50 is arranged in the second air duct section 11, which can detect refrigerant leakage within a specified time under the condition that the fan 30 is on or off.

[0056] As Figure 2As shown, compared to the first air duct section 12, the second air duct section 11 houses the evaporator 20. The evaporator 20 has a plate-like structure and occupies less space. Therefore, the space inside the second air duct section 11 is more spacious than that inside the first air duct section 12, making it easier to install the refrigerant leak detector 50. Furthermore, the airflow in the second air duct section 11 is better than in the first air duct section 12. This allows the refrigerant to spread more quickly into the second air duct section 11 when the fan 30 is not running, enabling more timely detection of refrigerant leaks. Moreover, refrigerant leaks are prone to occur at the pipe welding points and bends of the evaporator 20. Placing the refrigerant leak detector 50 inside the second air duct section 11 also allows for faster detection of refrigerant leaks.

[0057] Optionally, such as Figures 3 to 5 As shown, the housing 1 includes a first side plate 113, a second side plate 114, and a mounting member 112.

[0058] The first side plate 113 is located along the length of the evaporator 20 (e.g., ...). Figure 3 The first side plate 113 is located at one end of the evaporator 20 in the left-right direction; the second side plate 114 is located at the other end of the evaporator 20 in the length direction and is arranged opposite to the first side plate 113.

[0059] Mounting member 112 is connected between the first side plate 113 and the second side plate 114. Mounting member 112, the first side plate 113, and the second side plate 114 together define the second air duct section 11. Refrigerant leak detector 50 is provided on mounting member 112.

[0060] The space between the first side plate 113 and the evaporator 20 is relatively small, and the space between the second side plate 114 and the evaporator 20 is also relatively small. In other words, the spaces at the first side plate 113 and the second side plate 114 are quite compact, resulting in poor airflow. Therefore, if the refrigerant leak detector 50 is placed at the first side plate 113 or the second side plate 114, the airflow to the first side plate 113 and the second side plate 114 will be slow when the fan 30 is not running, preventing the refrigerant detector from detecting a refrigerant leak within the specified time.

[0061] like Figure 2 As shown, the mounting component 112 is positioned opposite to the plane containing the length and width of the evaporator 20. The refrigerant leak detector 50 is mounted on the mounting component 112, so that the refrigerant leak detector 50 is also positioned opposite to the plane containing the length and width of the evaporator 20. In this way, when a refrigerant leak occurs at the evaporator 20, the refrigerant leak detector 50 can detect the refrigerant leak more quickly.

[0062] Furthermore, the space at the mounting component 112 is relatively spacious, and the refrigerant leak detector 50 is located at the mounting component 112. On the one hand, this reduces the difficulty of installation, and on the other hand, the airflow at the mounting component 112 is smoother, which can further increase the sensitivity of the refrigerant leak detector 50.

[0063] Optionally, after the indoor unit is correctly installed, the mounting bracket 112 is positioned above or below the evaporator 20.

[0064] Since the density of refrigerant is greater than that of air, leaked refrigerant will flow downwards. With the mounting component 112 located below the evaporator 20, more refrigerant can flow to the mounting component 112, thereby further improving the detection sensitivity of the refrigerant leak detector 50.

[0065] When the mounting component 112 is located above the evaporator 20, the refrigerant leak detector 50 can quickly detect refrigerant leaks due to factors such as the close proximity of the mounting component 112 to the evaporator 20 and the relatively spacious space between the mounting component 112 and the evaporator 20.

[0066] Optionally, mounting component 112 is made of metal.

[0067] Mounting component 112 is made of metal. The metal material has high structural strength and strong resistance to plastic deformation, which improves the load-bearing capacity and durability of mounting component 112, and also increases the reliability and safety of mounting component 112, which can meet the installation strength requirements of refrigerant leak detector 50.

[0068] It is understandable that mounting part 112 can also be made of plastic.

[0069] The housing 1 also includes a first support member 116, which is disposed opposite to the mounting member 112. The first side plate 113, the second side plate 114, the first support member 116, and the mounting member 112 together enclose the second air duct section 11. The first support member 116 bears relatively small forces; therefore, to reduce the cost of the air conditioner, the first support member 116 is often made of plastic. Compared to placing it on the first support member 116, placing the refrigerant leak detector 50 on the metal mounting member 112 can improve the installation stability of the refrigerant leak detector 50, and also eliminates the need to make the first support member 116 metal, thus ensuring the cost of the air conditioner.

[0070] like Figure 1 and Figure 3 As shown, the outer casing also includes a third side plate 122 and a fourth side plate 115. The third side plate 122 is connected between one end of the first side plate 113 and one end of the second side plate 114, and the fourth side plate 115 is connected between one end of the first side plate 113 and the other end of the second side plate 114. The connection between the mounting member 112 and the fourth side plate 115 forms an angle. An air outlet is located on the fourth side plate 115. An air guide plate 1151 is provided at the air outlet, and the air guide plate 1151 is movably connected to the outer casing to open or close the air outlet.

[0071] like Figure 2As shown, the shell further comprises an air inlet plate 123 and a second support 121, the air inlet plate 123 is arranged between the first support 116 and the third side plate 122, the air inlet 1231 is arranged on the air inlet plate 123, the air inlet plate 123 and the second support 121 are oppositely arranged, the second support 121 is arranged between the third side plate 122 and the mounting 112, and the air inlet plate 123 and the second support 121 are respectively located on the opposite sides of the fan 30. The third side plate 122, the air inlet plate 123 and the second support 121 jointly enclose the first air duct section 12.

[0072] Optionally, as shown, the mounting 112 is provided with a reinforcing rib 1121. Figure 3

[0073] The mounting 112 is provided with a reinforcing rib 1121, and the number and shape of the reinforcing rib 1121 are not limited. For example, the number of reinforcing ribs 1121 is multiple, the reinforcing rib 1121 can be annular, or can be in the shape of a long strip, or any other shape.

[0074] The mounting 112 and the second support 121 are of an integral structure, the reinforcing rib 1121 extends along the length direction of the combination of the mounting 112 and the second support 121, part of the reinforcing rib 1121 is arranged on the mounting 112, and part of the reinforcing rib 1121 is arranged on the second support 121. The long-strip-shaped reinforcing rib 1121 extends along the length direction of the combination, the annular reinforcing rib 1121 comprises a first rib section 1122, a second rib section 1123, a third rib section 1124 and a fourth rib section 1125, the first rib section 1122 and the second rib section 1123 both extend along the length direction of the mounting 112, the third rib section 1124 is arranged between the first rib section 1122 and the second rib section 1123 and connected with the first end of the first rib section 1122 and the first end of the second rib section 1123, the connection forms a bend, the fourth rib section 1125 is arranged between the first rib section 1122 and the second rib section 1123 and connected with the second end of the first rib section 1122 and the second end of the second rib section 1123, the connection forms a bend, the first rib section 1122 and the second rib section 1123 are oppositely arranged, the third rib section 1124 and the fourth rib section 1125 are oppositely arranged, the first rib section 1122, the second rib section 1123, the third rib section 1124 and the fourth rib section 1125 form a ring, and the refrigerant leakage detector 50 is located in the middle.

[0075] The arrangement of the reinforcing rib 1121 can improve the carrying capacity and stability of the mounting 112, and also enhance the structural strength of the mounting 112, so that the mounting 112 can stably support the refrigerant leakage detector 50.

[0076] The refrigerant leakage detector 50 is arranged at the reinforcing rib 1121 or deviates from the reinforcing rib 1121.

[0077] ​Optionally, the refrigerant leakage detector 50 is arranged on the evaporator 20. The refrigerant leakage detector is arranged on the surface of the evaporator or arranged inside the evaporator.

[0078] The refrigerant leakage detector 50 can also be arranged directly on the evaporator 20, which can reduce the distance between the refrigerant leakage detector 50 and the evaporator 20, so that the refrigerant leakage detector 50 can detect refrigerant leakage in time and improve the safety of the air conditioner.

[0079] Optionally, as shown in Figure 4 and Figure 5 , the refrigerant leakage detector 50 is arranged at the middle of the length direction of the evaporator 20.

[0080] When the refrigerant leakage detector 50 is arranged on the evaporator 20, the refrigerant leakage detector 50 is arranged at the middle of the length direction of the evaporator 20; when the refrigerant leakage detector 50 is arranged on the mounting member 112, the refrigerant leakage detector 50 is arranged on the mounting member 112 corresponding to the middle of the length direction of the evaporator 20, that is, arranged at the middle of the length direction of the mounting member 112. In this way, when refrigerant leakage occurs at different positions of the length direction of the evaporator 20, the refrigerant can quickly spread to the refrigerant leakage detector 50, so that the detection of the refrigerant leakage detector 50 is more accurate and the detection sensitivity is improved.

[0081] Optionally, as shown in Figure 4 and Figure 5 , the refrigerant leakage detector 50 is arranged at the middle of the width direction of the evaporator 20.

[0082] When the refrigerant leakage detector 50 is arranged on the evaporator 20, the refrigerant leakage detector 50 is arranged at the middle of the width direction of the evaporator 20; when the refrigerant leakage detector 50 is arranged on the mounting member 112, the refrigerant leakage detector 50 is arranged on the mounting member 112 corresponding to the middle of the width direction of the evaporator 20, that is, arranged at the middle of the width direction of the mounting member 112. In this way, when refrigerant leakage occurs at different positions of the width direction of the evaporator 20, the refrigerant can quickly spread to the refrigerant leakage detector 50, so that the detection of the refrigerant leakage detector 50 is more accurate and the detection sensitivity is improved.

[0083] Optionally, as shown in Figure 2 , the evaporator 20 is arranged obliquely in the second air duct section 11.

[0084] The oblique arrangement of the evaporator 20 can reduce the thickness of the indoor unit and form a thinner indoor unit.

[0085] The evaporator 20 is arranged obliquely between the first supporting member 116 and the mounting member 112.
