Description

TECHNICAL FIELD

[0001] The utility model belongs to air conditioning technology field, concretely relates to a compressor shell subassembly, compressor, air conditioner. BACKGROUND

[0002] The compressor is an important component of the air conditioner, and the compressor compresses and drives the refrigerant in the refrigerant circuit. The compressor is generally installed in the outdoor unit of the air conditioner, and the compressor provides driving force for the refrigerant. A temperature sensor is usually provided on the compressor, the temperature sensor is inserted in the sleeve, and the temperature sensor is fixed on the compressor exhaust pipe by the tightening belt and the heat preservation pipe to detect the temperature. The fixing structure of the temperature sensing bag has low assembly efficiency and cannot meet the needs of automatic assembly line, and the detected temperature has hysteresis. The air conditioner controls the compressor according to the temperature data detected by the temperature sensor, and there is a possibility that the protection action cannot be taken in time, thereby causing the compressor to have a motor demagnetization failure and other failure conditions.

[0003] In order to overcome the shortcomings of the prior art, Figure 1 As shown in the related art, a temperature sensor fixing bracket assembled on the compressor shell can effectively position and fix the sensor in the vertical direction, but in the horizontal direction, since it needs to ensure that the sensor can be smoothly inserted into the fixing bracket, the left and right sides of the fixing bracket need to form a certain gap with the left and right sides of the sensor, that is, there is a lack of necessary compression and fixation in the horizontal direction, which leads to an unclear installation position of the sensor after insertion. The consistency of the position of the sensor relative to the compressor (mainly relative to the bracket position) of different compressors with the same scheme is poor. In specific application conditions, the bottom of the accommodating cavity (i.e. the space for inserting the temperature sensor) in the fixing bracket is connected to the high-temperature compressor shell (housing or upper cover), and the remaining part is located in the air conditioner outdoor unit with complex temperature environment, so the temperature environment inside the accommodating cavity is also quite different. Generally, it is believed that the temperature near the compressor side in the accommodating cavity and the temperature at the middle position of the accommodating cavity are relatively high, and the temperature near the remaining side and the top surface of the accommodating cavity is relatively low. This is because the metal has good thermal conductivity, and the closer to the thin-walled metal side, the lower the temperature. Due to the poor position consistency of the sensor in the horizontal direction, the temperature information collected by the sensor is inaccurate, which leads to the control of the air conditioning system on the compressor not consistent with the expectation, and more seriously, it may cause the compressor to burn out and the air conditioner to fail.

DETAILED DESCRIPTION

[0040] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0041] In the description of the utility model, it is understood that the orientation words such as '' front, back, up, down, left, right '' '' horizontal, vertical, perpendicular, horizontal '' and '' top, bottom '' and the like indicated orientation or positional relationship is usually based on the orientation or positional relationship shown in the drawing, only for the convenience of describing the utility model and simplifying the description, in the absence of the opposite statement, these orientation words do not indicate and imply the device or element must have a particular orientation or be constructed and operated in a particular orientation, therefore can not be understood as the restriction of the protection scope of the utility model;The orientation words '' inside, outside '' refer to the inside and outside relative to the contour of each component.

[0042] For the convenience of description, spatial relative terms can be used here, such as '' above'', '' above'', '' upper surface'', '' upper '' and the like, to describe the spatial position relationship of one device or feature with other devices or features as shown in the drawing. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation of the device described in the drawing. For example, if the device in the drawing is inverted, the device described as '' above '' or '' above '' other devices or structures will be positioned '' below '' or '' below '' other devices or structures. Thus, the exemplary term '' above '' can include both '' above '' and '' below '' orientations. The device can also be positioned in other different ways (rotated 90° or in other orientations), and the spatial relative description used here is interpreted accordingly.

[0043] In addition, it should be noted that the use of '' first'', '' second '' and the like to limit parts is only for the convenience of distinguishing the corresponding parts, and the above words have no special meaning unless otherwise stated, therefore can not be understood as the restriction of the protection scope of the utility model.

[0044] Referring to Figure 1 And Figure 18As shown, according to the embodiment of the utility model, provide a kind of compressor shell assembly, including compressor shell (not marked in drawing) and the sensor fixing frame 1 of fixed connection on the compressor shell, the sensor fixing frame 1 including fixed frame body 11 and the connecting seat 12 at the both side end of this fixed frame body 11, the sensor fixing frame 1 via the connecting seat 12 and compressor shell form fixed connection, for example, corresponding welding point (not marked in drawing) is equipped on the bottom surface of connecting seat 12, to facilitate the convenient and reliable welding between connecting seat 12 and compressor shell, the fixed frame body 11 and the compressor shell form the containing passage (not marked in drawing) for the temperature measurement fixed section of temperature sensor 100 between, the inner wall surface of the containing passage is equipped with pressure holding structure (not marked in drawing), the pressure holding structure is continuously or spaced along the length extension direction of the containing passage, and the pressure holding structure includes horizontal pressure and vertical pressure to the temperature measurement fixed section (of outer circumferential wall) The exerted pressure includes horizontal pressure and vertical pressure, it needs to be explained that, the pressure holding structure is continuously arranged along the length extension direction of the containing passage specifically refers to, the pressure holding structure is arranged from front to back in the axial direction (that is, length direction or sensor insertion direction) of fixed frame body 11, and the pressure holding structure has at least two groups spaced along the axial direction of fixed frame body 11, to form bidirectional pressure holding fixed (that is, horizontal pressure and vertical pressure) to each end of the length of sensor. The vertical pressure and vertical pressure can be formed by two force points, or by one force point. The temperature measurement fixed section is a cylindrical section in one specific embodiment.

[0045] In the technical solution, the pressure holding structure is arranged on the inner wall surface of the containing passage, and the pressure holding structure can exert horizontal pressure and vertical pressure on the temperature measurement fixed section of the temperature sensor, i.e., form horizontal and vertical pressure holding and fixing of the temperature sensor, ensure the position determination and stability of the sensor after insertion, and overcome the inaccuracy of temperature information acquisition caused by poor position consistency of the temperature sensor in the horizontal direction in the prior art, which leads to the inconsistency between the control of the air conditioning system on the compressor and the expectation, and even leads to the burning of the compressor and the failure of the air conditioner. In addition, since the pressure holding structure is continuously or spaced along the length extension direction of the containing passage, it can also prevent the end lifting of the sensor during use due to single-end fixing, which leads to the failure and misalignment of the sensor.

[0046] In a specific embodiment, referring to Figures 2 to 6As shown, the fixed frame 11 has a top plate 111, side plates 112 on both sides of the top plate 111, and a connecting seat 12 at one end of the side plate 112 away from the top plate 111. The inner wall surface of the top plate 111 is provided with a vertical pressing and fixing portion 21. In a specific embodiment, the aforementioned vertical pressing and fixing portion 21 is located at the middle position of the width of the inner wall surface of the top plate 111. At least one side of the vertical pressing and fixing portion 21 is also provided with a lateral pressing and fixing portion 22. The lateral pressing and fixing portion 22 is located on the inner wall surface of the top plate 111 and / or the side plate 112, and the lateral pressing and fixing portion 22 can at least provide the horizontal pressing force. The aforementioned vertical pressing and fixing portion 21 and the lateral pressing and fixing portion 22 together form the aforementioned pressing and fixing structure.

[0047] In this technical solution, a vertical pressure-holding fixing portion 21 centrally arranged on the top plate 111 applies force to the sensor in the vertical direction, and a lateral pressure-holding fixing portion 22 on the side plate 112 or the top plate 111 located on at least one side of the aforementioned vertical pressure-holding fixing portion 21 provides at least a pressing force in the horizontal direction, thereby achieving bidirectional pressure on the temperature sensor 100 and ensuring the position consistency of the sensor.

[0048] See Figure 2 or Figure 5 As shown, the sensor fixing frame shown in the figure is provided with a group of vertical pressing and fixing parts 21 and a group of lateral pressing and fixing parts 22. It can be understood at this time that the aforementioned lateral pressing and fixing parts 22 press the temperature sensor 100 in the horizontal direction on the side plate 112 arranged opposite thereto by relying on its own elastic force, that is, at this time the side plate 112 also serves as a part of the aforementioned pressing and fixing structure to a certain extent, which makes the overall structure of the fixing frame simple and simplifies the processing process.

[0049] See Figure 4 and Figure 5 As shown, in another specific embodiment, a set of lateral pressing and fixing parts 22 are provided on both sides of the vertical pressing and fixing part 21, and the two sets of lateral pressing and fixing parts 22 are symmetrical about the vertical symmetry plane of the temperature sensor 100. Figure 5 As shown in the example, three groups of pressing and fixing parts are arranged on the top plate 111, among which the central vertical pressing and fixing part 21 is used for vertical pressing force, and the lateral pressing and fixing parts 22 on both sides are arranged on the arc-shaped top plate 111, so that they can provide the aforementioned vertical pressing force and lateral pressing force at the same time, and the force on the temperature sensor 100 is more reliable and uniform. It is worth emphasizing that at this time, the temperature sensor 100 objectively does not have any contact with the inner wall surface of the aforementioned top plate 111 and the side plate 112, which reduces the flatness processing accuracy requirements at the inner wall surface matching area, thereby further simplifying the processing technology of the fixing frame.

[0050] In some embodiments, the fixing frame 11 has a top plate 111, side plates 112 on both sides of the top plate 111, and a connecting seat 12 at one end of the side plates 112 away from the top plate 111. A set of lateral pressing and fixing parts 22 are provided on the inner side wall of at least one side of the side plates 112 and / or on the inner side wall of the top plate 111 at a non-center position. The lateral pressing and fixing parts 22 can simultaneously provide the vertical pressing force and the horizontal pressing force. Figure 7 As shown, a single-sided lateral pressing and fixing portion 22 is provided on the inner wall surface of the side plate 112, which applies force to the temperature sensor 100 in an inclined manner, as shown by the arrow in the figure. The force has a horizontal component and a vertical component, that is, the aforementioned horizontal pressing force and vertical pressing force, wherein the vertical component can ensure close contact between the sensor and the compressor housing, and the horizontal component can also press the sensor on the inner wall surface of the side plate 112 to ensure that the horizontal position of the sensor is consistent and stable, that is, in this technical solution, the aforementioned lateral pressing and fixing portion 22 and the side plate 112 arranged opposite thereto jointly form the aforementioned pressing and fixing structure, the structure and processing technology are relatively simple, and the position of the temperature sensor 100 is reliable and stable.

[0051] In some specific embodiments, the cross section of the top plate 111 is an arc or an isosceles triangle with an opening facing inward (eg Figure 13 ) or an isosceles trapezoid with the large base facing inward (such as Figure 14 、 Figure 12 ) to adapt to different installation conditions. For example, when the external space of the compressor is large and the diameter of the temperature sensor is large, the following can be used: Figure 12 and Figure 14 The top plate 111 structure type can make the overall span (ie width) of the fixing frame 11 relatively small, which is convenient for the arrangement of the outer parts of the compressor housing and prevents the installation of the fixing frame from occupying too much of the outer parts of the compressor housing; when the external space of the compressor is small and the diameter of the temperature sensor is small, it can be used Figure 13 The structure of the top plate 111 shown has a relatively small height required for the installation of the fixing frame, and its flat structure enables it to be assembled in a relatively small gap.

[0052] In some embodiments, the force direction of the lateral pressing fixing portion 22 on the temperature sensor 100 is aligned with the contact temperature measurement plane of the temperature sensor of the compressor housing (ie, Figure 7The angle α is formed between the top surface of the housing / upper cover and the horizontal plane shown in FIG. 2, 20°<α<70°. The lateral pressing and fixing portion 22 is arranged within this area so that the pressing force on the sensor has a component in both the horizontal and vertical directions, thereby limiting and fixing the sensor in two directions. Figure 7 As shown, at this time, only one set of the aforementioned lateral pressing and fixing parts 22 on one side can be set to achieve bidirectional reliable positioning of the temperature sensor 100 with the assistance of the side plate 112 set opposite thereto. The structure is particularly simple, and more importantly, it can also be particularly convenient for the temperature sensor 100 to be inserted into the accommodating channel.

[0053] In some embodiments, the lateral pressing and fixing portion 22 includes a plurality of lateral pressing members 221 spaced apart along the length of the accommodating channel; and / or, when a vertical pressing and fixing portion 21 is included, the vertical pressing and fixing portion 21 includes a plurality of vertical pressing members 211 spaced apart along the length of the accommodating channel. The plurality of lateral pressing members 221 and the plurality of vertical pressing members 211 are spaced apart along the length of the accommodating channel and, in principle, cover the entire axial length of the sensor, ensuring that the force applied to the temperature sensor 100 is uniform and controllable.

[0054] In some embodiments, the vertical pressing member 211 is a curved convex point 23a (such as Figure 6 As shown), cantilever spring 23b (as Figure 10 As shown), elastic bridge piece 23c (as Figure 16 and / or, the lateral pressing member 221 is one of a curved convex point 23a protruding toward one side of the accommodating channel, a cantilever spring 23b, and an elastic bridging piece 23c.

[0055] In this technical solution, several preferred structural types of the vertical pressing member 211 and the lateral pressing member 221 are provided. Among them, the arc surface convex point 23a has a relatively small elastic deformation capacity and can provide a relatively large interference pressing force, so it is more suitable for locations where the mounting space of the fixed frame is relatively limited; the cantilever spring piece 23b has a large elastic capacity, so its force on the sensor is also easier to control; the elastic bridge piece 23c is specifically described in detail. Figure 16 As shown, both ends are connected to the top plate 111 or the side plate 112. Since the whole forms a bridge structure with both ends fixed, its elastic deformation is between the aforementioned arc surface protrusion 23a and the cantilever spring piece 23b, and the compression and fixation of the temperature sensor 100 is more stable and controllable.

[0056] In a preferred embodiment, the arc convex point 23a, the cantilever spring 23b and the elastic bridge 23c are formed by stamping on the top plate 111 or the side plate 112.

[0057] Figure 17 and Figure 18 The pressing fixing structure is shown in a specific implementation mode of being arranged at intervals in the length extension direction of the accommodating channel.

[0058] Specifically, as shown in Figure 17 The accommodating channel has an insertion entry end (not marked in the figure) and an insertion tail end (not marked in the figure), the fixing frame body 11 has a top plate 111, side plates 112 on both sides of the top plate 111 and a connecting seat 12 at the end of the side plate 112 away from the top plate 111, the pressing fixing structure includes a front end pressing fixing part 31 arranged on the end face of the top plate 111 corresponding to the insertion entry end and a rear end pressing fixing part 32 arranged on the end face of the top plate 111 corresponding to the insertion tail end, the front end pressing fixing part 31 and the rear end pressing fixing part 32 are both cantilever structures and the inner side wall surface of the front end pressing fixing part 31 and the rear end pressing fixing part 32 has an envelope surface matching the outer circumferential wall surface of the temperature sensing fixed section, the envelope surface is a circular arc wall surface surrounding at least the top side area of the temperature sensing fixed section of the temperature sensor 100.

[0059] In the technical solution, the front end pressing fixing part 31 and the rear end pressing fixing part 32 are both cantilever structures, which can exert an elastic interference force on the temperature sensor 100, and because they have an envelope surface matching the outer circumferential wall surface of the temperature sensing fixed section, they can exert the vertical pressing force and the horizontal pressing force on the sensor, that is, they can press the two end positions of the sensor in two directions, preventing the end head from being raised, displaced or even falling off.

[0060] In some embodiments, the front end pressing fixing part 31 and the rear end pressing fixing part 32 are both formed with open interval grooves 33 (through the inner and outer sides of the pressing fixing part), each of the open interval grooves 33 extends along the length extension direction of the accommodating channel, and preferably, the open interval grooves 33 are at the central position of the width of the front end pressing fixing part 31 and the rear end pressing fixing part 32, so that the corresponding pressing fixing part forms a structure symmetrical about the vertical center plane of the sensor, and the force exerted is more balanced.

[0061] The gap exists between the inner side wall surface of the top plate 111 and the temperature measuring fixed section, that is, the inner side surface of the top plate 111 is higher than the top surface of the sensor to avoid the contact between the two to generate friction force and increase the installation difficulty during the sensor installation. At this time, it can be understood that the front end pressing fixed part 31 and the rear end pressing fixed part 32 are respectively connected by the downwardly inclined connecting plate to realize the interference fit connection between the pressing fixed part and the sensor.

[0062] Specifically referring to Figure 18 In another specific embodiment, the accommodating channel has an installation inlet end and an installation tail end, the fixed frame body 11 has a top plate 111, side plates 112 on both sides of the top plate 111, and a connecting seat 12 at an end of the side plate 112 away from the top plate 111, the pressing fixed structure includes a front end pressing fixed part 31 arranged on the end surface of the top plate 111 corresponding to the installation inlet end and a rear end pressing fixed part 32 arranged on the end surface of the top plate 111 corresponding to the installation tail end, the front end pressing fixed part 31 and the rear end pressing fixed part 32 are both cantilever structures and are both flat plate structures, and at least one inner wall surface of the side plate 112 is further provided with a lateral pressing fixed part 22, and the lateral pressing fixed part 22 can at least provide the horizontal pressing force. Figure 17 The difference between the structure of the fixed frame shown in the embodiment and the structure of the fixed frame shown in the embodiment is that the position of the temperature sensor 100 is positioned by the front end pressing fixed part 31, the rear end pressing fixed part 32 and the lateral pressing fixed part 22 on the side plate 112.
