Description

  The present invention relates to a fixing structure for arranging and fixing a heat exchanger at an attachment position in a casing in an outdoor unit of an air conditioner.

  For example, some outdoor units of an air conditioner include two heat exchangers in order to increase heat exchange efficiency. In such an outdoor unit, as shown in Patent Document 1, the heat exchangers are fixed in the casing of the outdoor unit so as to be symmetrical, for example.

  When assembling such an outdoor unit equipped with a plurality of heat exchangers, first put a compressor, electrical box, piping, etc., and then place the two heat exchangers at their respective mounting positions along the outer periphery of the casing. Deploy.

  By the way, since the front side of the casing is substantially closed by a compressor, an electrical box, piping, and the like, it is difficult to move each heat exchanger from the front side of the casing to each mounting position. Therefore, each heat exchanger is moved from the rear side of the casing to the inside and is disposed at a predetermined mounting position.

  However, the work space is often limited by the rear side of the casing being placed close to the wall, etc., and the operator confirms whether the current position of the heat exchanger has reached the mounting position. It is difficult to position the mounting position with high accuracy.

  Also, if the two heat exchangers are not accurately positioned at the respective mounting positions, the size of the gap formed between the end portions of each heat exchanger will change, and the size of the screen for closing the gap will be large. It will not fit. Then, for example, the partition between the end portions cannot be completely blocked by the partition, and the amount of wind flowing into the outdoor unit from the gap without passing through the heat exchanger as designed increases, and the heat exchange efficiency decreases. This will cause problems.

JP 2002-267209 A

  Then, this invention was made | formed in view of the above problems, and it aims at providing the fixing structure which can arrange | position two heat exchangers in a casing simply and accurately.

  That is, the fixing structure of the present invention is a fixing structure for fixing the first heat exchanger and the second heat exchanger to the respective mounting positions in the casing, and a fixing body fixed to the bottom surface of the casing; The first attachment body attached to the end of the first heat exchanger, the second attachment body attached to the end of the second heat exchanger, and between the fixed body and the first attachment body, or the fixed A first positioning structure that is formed on a body and guides the first heat exchanger to a predetermined first mounting position by pressing the first mounting body against the fixed body; The second heat exchanger is formed between the first mounting body and the second mounting body or on the fixed body, and by pressing the second mounting body against the first mounting body. Is the second position that leads to a predetermined second mounting position And the first mounting body or the second mounting body is disposed at the first mounting position and the second mounting position, in which the first heat exchanger and the second heat exchanger are determined in advance. In this state, the first heat exchanger and the second heat exchanger are configured to close the gaps between the end portions.

  If it is such, on the basis of the fixed body fixed to the bottom surface of the casing, the operator presses the first attachment body attached to the first heat exchanger against the fixed body to press the first attachment body. The first heat exchanger can be naturally arranged at the first mounting position by the one-positioning structure. Similarly, with respect to the second heat exchanger, the second positioning is performed by pressing the second mounting body attached to the second heat exchanger against the first mounting body fixed to the fixed body. According to the structure, the second heat exchanger can be naturally arranged at the second mounting position.

  In other words, heat exchangers must be mounted from the rear side of the casing, and even if it is difficult to check the placement of each heat exchanger at each mounting position, Since the exchanger is arranged at each mounting position, the operator presses the first mounting body or the second mounting body against the fixed body, so that each heat exchanger is placed at each mounting position in the casing. It can be determined that it has been placed.

  Therefore, it is not necessary for the operator to proceed with the placement work while checking the degree of deviation of the current position of the heat exchanger from the mounting position while mounting each heat exchanger in the casing. The heat exchanger can be easily placed and fixed.

  In addition, the fixing of each heat exchanger in the casing can be realized by only three parts such as the fixed body, the first mounting body, and the second mounting body.

  Further, since the first mounting body or the second mounting body is configured to close the gap between the end portions of each heat exchanger, a separate partition is provided to block the wind passing through the gap of each heat exchanger. There is no need to provide it.

  From these facts, it is possible to reduce the number of parts necessary for fixing each heat exchanger and to reduce the manufacturing cost.

  As a specific configuration for pressing the first mounting body against the fixed body so that the first heat exchanger is accurately arranged with respect to the first mounting position, A positioning structure is formed on the fixed body and a fitting structure including a receiving portion and an insertion portion formed between the fixed body and the first mounting body, and the fixed body and the fixed body are formed by the fitting structure. What is comprised from the 1st stopper part which contacts the said 1st heat exchanger in the state which the said 1st attachment body fitted is mentioned.

  If it is such, when the said 1st attachment body fits with respect to the said fixed body, the attitude | position of the said 1st attachment body will be controlled by a certain attitude | position, and the said 1st attachment body is attached. The position and posture of the first heat exchanger are also adjusted. Furthermore, since the pushing amount and posture of the first heat exchanger into the casing are adjusted by the first stopper portion, the first heat exchanger can be accurately arranged at the first mounting position.

  By simply pressing the second mounting body against the first mounting body fixed to the fixed body, the position and orientation of the second heat exchanger are adjusted, and the second mounting body is accurately placed at the second mounting position. As a specific configuration example for making it possible, the second positioning structure includes an engaging portion and an engaged portion formed between the first mounting body and the second mounting body. A temporary holding structure and a second body that is formed on the fixed body and contacts the second heat exchanger in a state where the second mounting body is temporarily held with respect to the first mounting body by the temporary holding structure. What is necessary is just to be comprised from the stopper part.

  If this is the case, the second mounting body is temporarily held by the first mounting body, thereby restricting the second mounting body to a certain posture. The position and attitude of the attached second heat exchanger are also adjusted. Further, since the second stopper is brought into contact with the second heat exchanger, the amount of the second heat exchanger to be pushed into the casing and the posture thereof are naturally adjusted, so that the second heat exchanger is also It becomes possible to arrange | position correctly to a 2nd attachment position. In addition, the temporary holding structure makes it possible to keep the fastening holes provided for screwing between the first mounting body and the second mounting body in close proximity, and adjust the displacement of the holes. Even if they are not equal, fixing work by screwing can be easily performed.

  Even if a member other than the heat exchanger is disposed at the center of the casing, the first heat exchanger is secured to the casing by screwing each member of the fixed structure without interfering with these other members. In order to make it easy to fix the inside, it is only necessary that the fixing body and the first mounting body are fitted to each other so as to be screwed to the fixing body from the first mounting body. If it is such, it will become possible to perform a fixing operation | work efficiently from the rear side of the casing on the opposite side to members other than the heat exchanger in the center part of a casing, for example.

  In order to make it easier to fix the second heat exchanger and further improve the assemblability, the second mounting body is temporarily attached to the first mounting body while the second mounting body is temporarily held. What is necessary is just to be comprised so that it may screw to the said 1st attachment body from a body.

  In order to prevent wind from passing through undesigned flow paths from the gaps between the heat exchangers and lowering the heat exchange efficiency, the first heat exchanger and the second heat heat exchanger are determined in advance. What is necessary is just to further provide the cover body which block | closes the clearance gap formed in the upper surface side of a said 1st heat exchanger and a 2nd heat exchanger in the state used as 1 attachment position and 2nd attachment position.

  If it is an outdoor unit using the fixing structure of the present invention, the assembling property and the positioning accuracy in fixing work of the heat exchanger can be significantly increased with a small number of parts of three as compared with the conventional one. Such costs can be reduced. In addition, each heat exchanger can be firmly fixed in the casing based on the fixed body, so that it can be held in the casing with rigidity so as not to deviate from the mounting position during transportation. .

  Thus, according to the fixing structure of the present invention, each positioning structure allows the operator to naturally place each heat exchanger at each mounting position simply by pressing each heat exchanger against the fixing body. Assembling property and positioning accuracy of each heat exchanger can be made very good. Conventionally, in order to avoid a decrease in heat exchange efficiency, a partition member and a partition for preventing wind from flowing into the outdoor unit from the gaps between the end portions of the heat exchangers are provided separately. According to the invention, the first mounting body or the second mounting body for fixing each heat exchanger can also serve as the function, and the number of parts can be reduced and the manufacturing cost can be reduced.

Then, by the second stopper portion 63, the second heat exchanger E2 is no longer moved to the front side CF in the casing C, so that the second heat exchanger E2 is positioned to the second mounting position. It is supposed to be.

  A procedure for mounting the heat exchangers E1 and E2 from the rear CR of the casing C using the fixing structure 100 configured as described above, positioning the heat exchangers at the respective mounting positions, and fixing them will be described.

  As shown in FIG. 4, members other than the heat exchangers E <b> 1 and E <b> 2 are arranged and fixed in the center of the casing C first. The fixing body 1 is screwed to the fixing portion 12 so that the opening side of the concave surface 51 of the receiving portion 11 faces the rear CR of the casing C at a predetermined fixing position in a substantially central portion of the casing C. Fixed. Here, the height of the receiving portion 11 in the vertical direction is set to be as short as about 1/5 with respect to the length in the vertical direction of the end portions of the heat exchangers E1 and E2, and thus is fixed. It is difficult to interfere with piping etc.

  When the fixed body 1 is fixed to the bottom surface CB of the casing C, the first heat exchanger E1 with the first mounting body 2 attached is pushed from the rear CR of the casing C to the front CF. At this time, the first heat exchanger E <b> 1 is a casing after the rough alignment is performed so that the convex surface 52, which is the insertion portion of the first attachment body 2, fits with the concave surface 51 of the receiving portion 11. It is pushed into the front CF of C.

  When the first mounting body 2 is pressed against the fixed body 1, the fitting structure 5F is fitted, and accordingly, the casing of the first mounting body 2 and the first heat exchanger E1. The position in the left-right direction in C approaches the first attachment position.

  When the fitting structure 5F is completely fitted, the end portion on the bottom surface CB side of the first heat exchanger E1 is in contact with the first stopper portion 53, and the front CF of the casing C is in contact with the front CF. The first heat exchanger E1 cannot be pushed any further. That is, the position of the first heat exchanger E1 in the front-rear direction and the left-right direction in the casing C is regulated by the fixed body 1, and as a result, as shown in FIGS. 5 and 6, the first heat exchanger E1 Is positioned at the first mounting position.

  Thereafter, the receiving portion 11 of the fixed body 1 and the first mounting body 2 are threaded from the rear CR of the casing C through screw holes formed so as to communicate with each other. The first mounting body 2 is screwed to complete the fixing of the first heat exchanger E1 in the casing C.

  Subsequently, as shown in FIG. 4, the second heat exchanger E <b> 2 with the second attachment body 3 attached thereto is pushed from the rear CR of the casing C to the front CF. At this time, after the side plate portion of the second mounting body 3 and the other side plate portion 22 of the first mounting body 2 are substantially aligned, the second heat exchanger E2 is positioned on the front side of the casing C. It is pushed into CF.

  When the second mounting body 3 is pressed against the first mounting body 2 and the fixed body 1, the temporary mounting structure 6 </ b> F including the engaging portion 61 and the engaged portion 62 causes the second mounting body. 3 is hooked to the first mounting body 2. That is, the position of the second attachment body 3 and the second heat exchanger E2 in the left-right direction in the casing C is set to the second attachment position by the engagement of the engaging portion 61 and the engaged portion 62. It will be fixed to the corresponding position.

  Further, when the second mounting body 3 is temporarily held with respect to the first mounting body 2 by the temporary holding structure 6F, the end portion on the bottom surface CB side of the second heat exchanger E2 is the second stopper portion. By contacting 63, the second heat exchanger E2 can no longer push the second heat exchanger E2 into the front CF of the casing C. That is, the position of the second heat exchanger E2 in the front-rear direction and the left-right direction in the casing C is regulated by the fixed body 1, and as a result, the second heat exchanger E2 is also the second heat exchanger E2 as shown in FIGS. 2 will be positioned to the mounting position.

  Thereafter, a bolt is passed from the rear CR to the screw hole formed so as to communicate between the bottom plate portion of the first attachment body 2 and the bottom plate portion of the second attachment body 3, and then the first attachment body 2. On the other hand, the second mounting body 3 is screwed to complete the fixing of the second heat exchanger E2 in the casing C. Here, since the bottom plate portion of the first attachment body 2 and the bottom plate portion of the second attachment body 3 are kept substantially in parallel by the temporary holding mechanism, the position adjustment such as matching each screw hole is performed. It is not necessary and can be easily screwed. More specifically, in a state where the second mounting body 3 is temporarily held with respect to the first mounting body 2, the bolts are tightened in order from the upper hole, so that the rear CR Without holding the second attachment body 3 against the first attachment body 2 by hand, the distance between the fastening portions adjacent to the portion tightened by the axial force of the bolt can be reduced. That is, the second mounting body 3 is fitted into the first mounting body 2 only by tightening the bolts in order from the upper side with respect to the first mounting body. The second mounting body 3 can be smoothly fixed to the first mounting body 2.

  Finally, the upper base portion of the substantially trapezoidal plate-like lid body 4 is covered with the lid body of the first mounting body 2 so as to close the vertical gap formed between the upper surfaces of the heat exchangers E1 and E2. Screwing the fixing portion 24 results in a state as shown in FIG.

  As described above, according to the fixing structure 100 of the present embodiment, the first mounting body 2 is pressed against the fixed body 1 and the first heat exchanger E1 is pressed against the first stopper portion 53. The first heat exchanger E1 is naturally positioned at the first mounting position when the end portions are in contact and cannot be pushed any further. Similarly, for the second heat exchanger E2, the second mounting body 3 is pressed against the first mounting body 2 and the fixed body 1, and the second stopper portion 63 is used for the second heat exchanger E2. The second heat exchanger E2 is naturally positioned to the second mounting position when it can no longer be pushed in contact with the end of the second heat exchanger.

  Therefore, the worker who performs the fixing work of each heat exchanger E1, E2 feels the reaction force that returns that each heat exchanger E1, E2 is in contact with each stopper, and then each heat exchanger E1, If pushing in E2 is complete | finished, each heat exchanger E1, E2 can be made into the state which was accurately located in each attachment position.

  That is, the operator can determine that the heat exchangers E1 and E2 are positioned at the respective mounting positions by having the heat exchangers E1 and E2 pressed against the stopper portions, and the rear CR Therefore, it is not necessary to confirm the positions of the heat exchangers E1 and E2 by visual recognition which is difficult from the viewpoint. Therefore, the heat exchangers E1 and E2 can be easily positioned and fixed to a predetermined mounting position in the casing C as compared with the conventional case.

The first mounting body 2 also closes the front-rear gap formed by the end portions of the heat exchangers E1 and E2 in a state where the heat exchangers E1 and E2 are fixed at the mounting positions. Since it is configured, it is possible to form an air path as designed by using only the fixed structure 100 without providing a separate partition or the like. Therefore, a place where four parts are originally required can be configured with only three parts, the number of parts necessary for fixing each heat exchanger E1, E2 can be reduced, and the manufacturing cost can be reduced. .
Furthermore, the separation width between the end portions between the heat exchangers E1 and E2, that is, the width dimension of the first mounting body 2 and the second mounting body 3 is determined from the rear CR of the casing C to each heat exchanger E1. , E2 is set so that the impact driver reaches the bottom plate portion 32 of the second mounting plate 3 without being obstructed, and the temporary holding structure 6F is used to tighten the bolts in order from the upper side. Since the bottom plate portion 23 of the first mounting body 2 and the bottom plate portion 32 of the second mounting body 3 are configured to naturally match without restraining, the fixing structure 100 can be smoothly inserted without assembling. Assembly can be completed.
