Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioning, and in particular relates to a compressor housing component, a compressor, and an air conditioner. Background Art

[0002] The compressor is a key component of an air conditioner, compressing and driving the refrigerant in the refrigerant circuit. The compressor is typically installed inside the air conditioner's outdoor unit, providing the driving force for the refrigerant. The compressor is typically equipped with a temperature sensor, inserted into a sleeve and secured to the compressor exhaust pipe using a tightening band and insulation tubing to detect temperature. This fixed structure of the temperature sensor has low assembly efficiency and cannot meet the requirements of automated assembly on production lines. Furthermore, the detected temperature has a lag. The air conditioner controls the compressor based on the temperature data detected by the temperature sensor, potentially preventing timely protective action, which can lead to compressor failures such as motor demagnetization.

[0003] In order to overcome the deficiencies of the aforementioned prior art, a temperature sensor fixing bracket assembled on the compressor housing is proposed in the related art, wherein the temperature sensor accommodating channel of the fixing bracket is designed to be a tapered structure, and the diameter size of the insertion inlet end of the accommodating channel is slightly larger than the cylinder of the temperature sensor to form a guide for the temperature sensor during assembly, and the diameter size of the accommodating channel is gradually reduced along the insertion direction of the sensor to achieve interference pressing of the temperature sensor; however, in this technical solution, the temperature sensor is fixed by the pressing action of the top plate and the side plates, and the top plate is connected to the connecting seat through the side plates, and the connecting seat is fixedly connected to the compressor housing. The deformation ability of the side plate position will directly affect the adjustment of the elastic reset force between the top plate and the temperature sensor. In terms of the related art The size of the accommodating channel tends to decrease from the entrance to the tail end, and a large interference fit is also set at the junction of the connecting seat and the accommodating channel. However, the sensor base has a large transverse span and is welded to the upper cover, so it is difficult to deform, and the deformation amount is uncontrollable. The provided clamping force is also very uncontrollable, resulting in large individual differences in the stress state of the sensor; with the same design and size, some compressor sensors are subjected to too much force, causing the bracket to crush the sensor, especially when the sensor is inserted, the probability of damage is even greater; at the same time, some clamping forces are too small, so that under the long-term working vibration of the compressor, the sensor falls off from the bracket, affecting the installation reliability of the sensor; when the aforementioned elastic reset force is not adjusted reasonably, the temperature sensor will become loose or crushed. Utility Model Content

[0004] Therefore, the utility model provides a compressor housing assembly, a compressor, and an air conditioner, which can solve the technical problem in the prior art that the side plate in the temperature sensor fixing bracket is connected to the connecting seat, which makes it difficult to adjust the pressing force of the side plate on the temperature sensor, thereby causing the sensor to be crushed.

[0005] In order to solve the above problems, the utility model provides a compressor housing assembly, including a compressor housing and a sensor fixing frame fixedly connected to the compressor housing, the sensor fixing frame including a fixing frame body and connecting seats connected to both sides of the fixing frame body, an accommodating channel for compressing the temperature measuring fixing section of the temperature sensor is formed between the fixing frame body and the compressor housing, the fixing frame body includes a top plate and side plates on both sides of the top plate, the side plates are connected between the connecting seat and the top plate, the distance between the positions where the side plates on both sides are connected to the connecting seat is L, the diameter of the temperature sensor is D, and the distance between the side plates on both sides and the connecting seat is L. When the temperature sensor is in an installed state, the top plate in pressurized contact with the temperature sensor has a maximum deformation cross-section. Any point on the inner wall surface of the top plate corresponding to the maximum deformation cross-section is point A. After the temperature sensor is installed, the distance between point A and the center point O of the temperature sensor is OB. Before the temperature sensor is installed, the distance between point A and point O is OA. The difference between OB and OA at the same point is (OB-OA). The maximum value of the difference (OB-OA) of each point is MAX(OB-OA), and DL≤MAX(OB-OA) / 3.

[0006] In some embodiments, L≥D; and / or, the temperature measurement fixed section is a cylindrical section.

[0007] In some embodiments, the top plate is a curved structure with a cross-sectional size decreasing along the insertion direction of the temperature sensor, and the distance between the two side plates is maintained at L along the insertion direction.

[0008] In some embodiments, both sides of the curved structure are connected to the corresponding side panels in a smooth transition.

[0009] In some embodiments, the curved surface structure is an arc structure, the accommodating channel has an insertion entrance end and an insertion tail end, and the radius R of the arc structure corresponding to the insertion entrance end is greater than the radius r of the arc structure corresponding to the insertion tail end.

[0010] In some embodiments, the top plate is a curved structure with a trend of decreasing cross-sectional size along the insertion direction of the temperature sensor, the accommodating channel has an insertion inlet end and an insertion tail end, the top ends of the two side panels are inclined toward the central symmetry plane of the accommodating channel, and the angle formed between the inner wall surface of the side panel close to the insertion inlet end and the bottom surface of the connecting seat is smaller than the angle formed between the inner wall surface of the side panel close to the insertion tail end and the bottom surface of the connecting seat, and the two sides of the curved structure are smoothly transitioned to the corresponding side panels.

[0011] In some embodiments, the curved surface structure is an arc structure, and a radius R of the arc structure corresponding to the insertion inlet end is greater than a radius r of the arc structure corresponding to the insertion tail end.

[0012] In some embodiments, the top plate is a planar structure that tends to decrease in height along the insertion direction of the temperature sensor, and a connecting plate is provided between the top plate and the side plate. When the temperature sensor is inserted into the accommodating channel, the connecting plate and the top plate are pressed against the temperature measurement fixed section of the temperature sensor.

[0013] In some embodiments, the top plate has an opening groove whose opening is located on the end surface of the insertion tail end of the accommodating channel, and the opening groove extends a preset distance along the axial direction of the temperature sensor.

[0014] The utility model also provides a compressor, comprising the above-mentioned compressor housing assembly.

[0015] The utility model also provides an air conditioner, comprising the above-mentioned compressor.

[0016] The compressor housing assembly, compressor, and air conditioner provided by the utility model have the following beneficial effects:

[0017] The difference between the diameter D of the temperature sensor and the distance L between the two side plates is less than one-third of the maximum deformation position of the top plate on the maximum deformation section, so that the pressing force applied to the temperature sensor by the side plate when in press contact with the temperature measurement fixed section of the temperature sensor is relatively small, thereby reducing the influence of uncontrollable force factors caused by uncontrollable deformation caused by the connection between the side plate and the connecting seat, and thus effectively preventing the occurrence of sensor damage caused by excessive force during and after the temperature sensor insertion process. It can be understood that the pressing force applied by the aforementioned top plate on the temperature sensor will be greater than the pressing force applied by the lower part of the side plate on the temperature sensor;

[0018] On the one hand, the cross-sectional dimension of the top plate tends to decrease in the insertion direction and is a curved structure. After the temperature sensor is inserted, the curved structure can wrap and fit the top surface area of ​​the temperature measurement fixed section of the temperature sensor and form a force to press it. The larger contact area can ensure reliable pressing and positioning of the temperature sensor, and effectively prevent scratches and compression caused by stress concentration during the insertion process. On the other hand, the side plates on both sides are parallel to each other and the interval is maintained at L. When L is greater than D, the uncontrollable adverse effect of the side plate on the temperature sensor is completely eliminated. Only the top plate is used to press the temperature sensor. The force is more controllable and the insertion is smoother. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0036] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90° or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0037] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0038] See also Figure 1 and Figure 12As shown, according to an embodiment of the present invention, a compressor housing assembly is provided, comprising a compressor housing (not shown in the figure) and a sensor fixing frame 1 fixedly connected to the outer side surface of the compressor housing, the sensor fixing frame 1 comprising a fixing frame body 11 and connecting seats 12 connected to both sides of the fixing frame body 11, the aforementioned sensor fixing frame 1 is fixedly connected to the compressor housing via the aforementioned connecting seat 12, for example, corresponding welding points (not marked in the figure) are provided on the bottom surface of the connecting seat 12, so as to facilitate convenient and reliable welding between the connecting seat 12 and the compressor housing, and an accommodating channel (not marked in the figure) for pressing the temperature measuring fixed section of the temperature sensor 100 is formed between the fixing frame body 11 and the compressor housing, the fixing frame body 11 comprises a top plate 111 and side plates 112 on both sides of the top plate 111, the side plates 112 are connected between the connecting seat 12 and the top plate 111, and the distance between the positions where the side plates 112 on both sides are connected to the connecting seats 12 on both sides is L (see Figure 4 ), the diameter of the temperature sensor 100 is D. When the temperature sensor 100 is in the inserted state, the top plate 111 in press-contact with the temperature sensor 100 has a maximum deformation cross section (which is perpendicular to the central axis of the temperature sensor 100). Specifically, Figure 4 and Figure 5 For example, let's assume that any point on the inner wall of the top plate 111 corresponding to the maximum deformation cross section is point A. After the temperature sensor 100 is installed, the distance between point A and the center point O of the temperature sensor 100 is OB. Before the temperature sensor 100 is installed, the distance between point A and point O is OA. The difference between OB and OA at the same point is (OB-OA), and the maximum value of the difference (OB-OA) at each point is MAX(OB-OA), with DL ≤ MAX(OB-OA) / 3. It should be noted that the center point O is on the central axis of the temperature sensor 100, and L is the maximum distance between the two side plates 112 (the horizontal distance between two opposing side surfaces).

[0039] In this technical solution, the difference between the diameter D of the temperature sensor 100 and the distance L between the two side plates 112 is less than one-third of the maximum deformation position point of the top plate 111 on the maximum deformation section, so that the pressing force applied by the side plate 112 on the temperature sensor 100 when it is pressed and contacted with the temperature measurement fixed section of the temperature sensor 100 is relatively small, thereby reducing the influence of the uncontrollable force factor caused by the uncontrollable deformation caused by the connection between the side plate 112 and the connecting seat 12, and thus effectively preventing the occurrence of sensor crushing caused by excessive force during and after the insertion of the temperature sensor 100. It can be understood that the pressing force applied by the aforementioned top plate 111 on the temperature sensor 100 will be greater than the pressing force applied by the lower part of the side plate 112 on the temperature sensor 100.

[0040] Figure 9 This is the simulation result when DL = MAX(OB-OA) / 3. Using the sensor holder of the technical solution of this application, when the design value DL = MAX(OB-OA) / 3, the top and side surface dimensions of different samples are precisely measured and statistically analyzed. Based on the statistical data, the compression force generated by the temperature sensor is simulated and calculated. As can be seen from the figure, although the compression force on the sensor from the side fluctuates greatly for different samples, it can be generally controlled below the compression force on the sensor from the top surface, thus eliminating the negative impact caused by this.

[0041] Figure 10 This is the simulation result when DL = MAX(OB-OA) / 4. When the design value DL = MAX(OB-OA) / 4, the top and side surface dimensions of different samples were carefully measured and statistically analyzed. Based on the statistical data, the compression force generated by the temperature sensor was simulated and calculated. As can be seen from the figure, the negative impact of the side surface on the sensor can be ignored, and a large design margin has been provided.

[0042] Figure 11 This is the simulation result when DL = 2MAX(OB-OA) / 3. When the design value DL = 2MAX(OB-OA) / 3 is used, the top and side surface dimensions of different samples are precisely measured and statistically analyzed. Based on this statistical data, the compression force generated by each sample pressing against the temperature sensor is simulated and calculated. As can be seen from the figure, the overall compression force on the sensor from the side is much greater than that from the top, and there is significant variation between samples. In this case, the side surface can significantly damage the sensor, and this also varies greatly from sample to sample.

[0043] Figure 12This is the simulation result when DL=MAX(OB-OA) / 2. When the design value DL=MAX(OB-OA) / 2, the top and side dimensions of different samples are precisely measured and counted, and the pressing force generated by the pressing temperature sensor is simulated based on the statistical data. As can be seen from the figure, compared with Figure 11 There has been a great improvement, but most samples still press the sensor from the side, and the individual differences in pressing force are still large.

[0044] In a specific embodiment, the temperature measurement fixed section is a cylindrical section.

[0045] In some embodiments, L≥D. At this time, that is, when the temperature sensor 100 is inserted into the accommodating channel, the connection position between the side plate 112 and the connecting seat 12 does not form pressure on the temperature sensor 100, thereby completely preventing the occurrence of sensor compression caused by uncontrollable force at this position. It can be understood that at this time, the temperature sensor 100 is reliably pressed and positioned by the upper area of ​​the side plate 112 and the top plate 111.

[0046] In some embodiments, the top plate 111 is a curved structure with a decreasing cross-sectional dimension along the insertion direction of the temperature sensor 100. The spacing between the two side plates 112 is maintained at L along the insertion direction, i.e., the side plates 112 on both sides are arranged in parallel and spaced apart. The cross-sectional profile of each of the curved structure's sections perpendicular to the central axis of the temperature sensor 100 is formed by smoothly connecting multiple arc segments with different radii but with the center of curvature on the same side. The aforementioned decreasing cross-sectional dimension trend specifically includes a situation where the cross-sectional dimension gradually decreases along the insertion direction, and also includes a situation where the cross-sectional dimension first gradually decreases and then remains at a smaller dimension along the insertion direction. In this case, the maximum deformation cross-sectional dimension is generally located at the location where the cross-sectional dimension of the receiving channel and the temperature sensor 100 is the smallest, such as the area corresponding to the rear end of the receiving channel and the temperature sensor 100. Of course, in some special cases, the location of the maximum deformation cross-sectional dimension may also be other locations, which can be verified based on actual simulation or experimental conditions.

[0047] In this technical solution, on the one hand, the cross-sectional dimensions of the top plate 111 tend to decrease in the insertion direction and are a curved surface structure. After the temperature sensor 100 is inserted, the curved surface structure can form a wrapping and adhesion to the top surface area of ​​the temperature measurement fixed section of the temperature sensor 100 and form a force pressing purpose. The large contact area can ensure the reliable pressing and positioning of the temperature sensor 100, while effectively preventing the occurrence of scratches and crushing caused by stress concentration during the insertion process. On the other hand, the side plates 112 on both sides are parallel to each other and the interval is maintained at L. When L is greater than D, the uncontrollable adverse effect of the side plates 11 on the temperature sensor 100 is completely eliminated. Only the top plate 111 is used to press the temperature sensor 100, and the force is more controllable and the insertion is smoother. The side plates on both sides are parallel and spaced at a distance of L, which can make the side pressure on the sensor more stable and facilitate the alignment and positioning of the parts when the bracket is welded to the upper cover.

[0048] In some embodiments, the two sides of the curved structure are smoothly connected to the corresponding side panels 112. It can be understood that the aforementioned smooth transition refers to the use of multiple curved surfaces with single curvature or multiple curvatures to achieve a smooth connection between the top panel 111 and the side panels 112. This can avoid the presence of ridges at the junction between the two, thereby preventing scratches and crushing caused by excessive local stress on the temperature sensor 100.

[0049] In some embodiments, the curved surface structure is an arc structure, and the accommodating channel has an insertion entrance end and an insertion tail end. The radius R of the arc structure corresponding to the insertion entrance end is greater than the radius r of the arc structure corresponding to the insertion tail end, that is, the contact position between the accommodating channel and the temperature sensor 100 is a semi-circular arc inner wall surface that gradually shrinks from R to r, which can form a tighter wrapping contact with the temperature sensor 100. The semi-circular arc inner wall surface utilizes the material deformation of the top plate to achieve up and down, left and right compression and limitation of the top surface area of ​​the temperature sensor 100. At this time, the side plate 112 only plays the role of reliably connecting the top plate 111 and the connecting seat 12 as a whole, and objectively does not contact the temperature sensor 100. It can be understood that the aforementioned insertion inlet end can be tangent to the side plate 112, that is, the arc structure corresponding to the aforementioned insertion inlet end is a semicircular arc, and the insertion tail end forms a smooth transition connection with the side plate 112 through the smooth curves on both sides to ensure that the two side plates 112 are arranged in parallel and equidistantly. Figure 6 and Figure 7 shown.

[0050] In some embodiments, the top plate 111 is a curved surface structure with a trend of decreasing cross-sectional size along the insertion direction of the temperature sensor 100, the accommodating channel has an insertion inlet end and an insertion tail end, and the top ends of the two side plates 112 are inclined toward the central symmetry plane of the accommodating channel, that is, on the cross section of the accommodating channel, the cross section formed by the two side plates 112 corresponding to each other forms an isosceles trapezoid, and the angle formed between the inner wall surface of the side plate 112 near the insertion inlet end and the bottom surface of the connecting seat 12 is smaller than the angle formed between the inner wall surface of the side plate 112 near the insertion tail end and the bottom surface of the connecting seat 12, as shown in FIG. Figure 8 As shown in the figure, α<β, and the two sides of the curved structure are smoothly connected to the corresponding side plates 112. By adopting this transition method, a more uniform transition can be achieved from the insertion entrance end to the insertion tail end, thereby avoiding a sudden change in the bracket due to the expansion force of the sensor, which leads to stress concentration.

[0051] In some embodiments, the curved surface structure is an arc structure, and the radius of the arc structure corresponding to the insertion entrance end is larger than the radius of the arc structure corresponding to the insertion tail end, that is, the contact position between the accommodating channel and the temperature sensor 100 is a semi-circular arc inner wall surface that gradually shrinks from R to r, which can form a tighter wrapping contact with the temperature sensor 100. The semi-circular arc inner wall surface utilizes the material deformation of the top plate to achieve the up and down, left and right compression and limitation of the top surface area of ​​the temperature sensor 100. At this time, the side plate 112 only plays the role of reliably connecting the top plate 111 and the connecting seat 12 into one, and objectively does not contact the temperature sensor 100.

[0052] In another feasible embodiment, the top plate 111 is a planar structure that decreases in height along the insertion direction of the temperature sensor 100, that is, the top plate 111 is a flat plate along the temperature sensor 100, and a connecting plate is provided between the top plate 111 and the side plate 112. When the temperature sensor 100 is inserted into the accommodating channel, the connecting plate and the top plate 111 are pressed against the temperature measurement fixed section of the temperature sensor 100. The aforementioned decreasing height trend includes the height of the top plate 111, that is, the distance between the bottom side of the top plate 111 and the compressor housing becoming smaller and smaller in the direction from the insertion entrance end to the insertion tail end of the accommodating channel, and also includes the height of the top plate 111 gradually decreasing for a certain length and then remaining unchanged at the lowest height. The top plate 111 adopts a planar structure instead of an arc structure, which can make the bracket structure simpler and reduce production and processing costs.

[0053] In some embodiments, the top plate 111 has an open groove on the end face of the insertion tail of the accommodating channel, and the open groove extends a preset distance along the axial direction of the temperature sensor 100. The aforementioned preset distance can be reasonably determined based on the relative position relationship between the axial length of the temperature measuring fixed section of the actual temperature sensor 100 and the accommodating channel. Generally speaking, the axial extension preset distance of the aforementioned open groove should not be less than half of the axial length of the temperature measuring fixed section to ensure that the top plate 111 has sufficient deformation during the insertion process of the temperature sensor 100, which facilitates the insertion of the sensor and can also effectively prevent the top plate 111 from causing damage to the sensor due to excessive pressure.

[0054] According to an embodiment of the present invention, a compressor is also provided, including the above-mentioned compressor housing assembly. In this case, the aforementioned compressor housing can specifically be a top cover or a compressor side wall, so as to accurately detect the real-time temperature inside the housing.

[0055] According to an embodiment of the present invention, an air conditioner is further provided, comprising the above-mentioned compressor.

[0056] It is easy for those skilled in the art to understand that, under the premise of no conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention. The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention. Such improvements and variations shall also be considered within the scope of protection of the present invention.
