Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to an evaporator bracket assembly, an indoor air conditioner unit, and an air conditioner. Background Technology

[0002] In existing technologies, cable trays are typically provided on the connecting brackets of evaporator support assemblies to allow cables to pass through. To avoid interference between electrical signals, high-voltage cables for supplying current are usually placed on one side of the connecting bracket, while low-voltage cables for signal transmission are placed on the other side. However, in some existing technologies, the temperature control probe used to detect the air inlet is located on the side with the high-voltage cables. The temperature control probe may be affected by electromagnetic interference generated by the current in the high-voltage cables, and a separate cable tray is also required for the temperature control probe to accommodate the low-voltage cables. Summary of the Invention

[0003] The first objective of this invention is to provide an evaporator support assembly to solve the technical problem of unreasonable cable arrangement in existing systems.

[0004] The evaporator support assembly provided by the present invention includes a connecting bracket and a temperature control probe. The connecting bracket has an air inlet configured to allow airflow passing through the evaporator to enter. The temperature control probe is mounted on the connecting bracket and is located to the right of the air inlet center position of the connecting bracket.

[0005] The beneficial effects of the evaporator support assembly of the present invention are:

[0006] By placing the temperature control probe on the left side of the air inlet of the connecting bracket, the temperature control probe and the low-voltage cable can be placed on the same side, reducing electromagnetic interference between high-voltage and low-voltage cables. This also reduces cable length, saving on air conditioner manufacturing costs. Furthermore, it eliminates the need for cable trays connecting the temperature control probe and the control box, minimizing damage to the evaporator bracket assembly structure. Additionally, since the airflow velocity is higher on the side of the indoor unit's air inlet in a cabinet air conditioner, placing the temperature control probe on this side allows for the measurement of this faster airflow velocity, thus improving measurement accuracy.

[0007] In a preferred embodiment, the connecting bracket is provided with an installation assembly, which includes a longitudinal support rod, a pressure rod, and a support flat rod. The support flat rod connects two vertically extending longitudinal support rods, and the pressure rod presses the temperature control probe against the support flat rod.

[0008] By using a pressure rod to press the temperature control probe firmly against the vertically extending longitudinal support rod and the supporting flat rod connecting the two longitudinal support rods, this pressing method not only ensures the stability of the temperature control probe during normal use, but also utilizes the elasticity of the pressure rod. Similarly, when disassembly or assembly is required, the pressure rod can deform in the direction away from the supporting flat rod, which also facilitates disassembly and assembly. Moreover, in the area outside the supporting flat rod, more of the surface around the temperature control probe comes into contact with the flowing air, allowing it to more fully sense the air temperature, thereby improving the accuracy of temperature measurement.

[0009] In a preferred embodiment, the mounting assembly includes multiple horizontal bars arranged vertically.

[0010] By setting up multiple horizontal bars arranged vertically, the temperature control probe can be evenly supported outwards. Alternatively, two longitudinal support bars can be connected to prevent bending in the middle of the longitudinal support bars, thereby improving the installation stability of the temperature control probe.

[0011] In a preferred embodiment, there are two pressure rods, which respectively abut against the upper and lower parts of the temperature control probe.

[0012] By using pressure rods to abut the temperature control probe from the top and middle, the entire temperature control probe can be firmly fixed on the mounting assembly, preventing the temperature control probe from swinging under the action of airflow and thus becoming loose.

[0013] In a preferred embodiment, the pressure bar is J-shaped, and the top ends of the J-shape of the two pressure bars are fixedly connected to one of the longitudinal support bars, with the free ends of the bent portions of the J-shape of the pressure bar facing the other longitudinal support bar.

[0014] The use of a J-shaped pressure rod allows for greater elasticity. When the temperature control probe is inserted, the distance between the free end of the bent part of the pressure rod and another longitudinal support rod is increased during the insertion process. After the temperature control probe is in place, the pressure rod springs back and presses against the temperature control probe, thus facilitating the insertion and fixation of the temperature control probe.

[0015] In a preferred embodiment, the connecting bracket includes a longitudinal rod, and the longitudinal support rod includes a first longitudinal support rod, which is fixedly connected to the longitudinal rod.

[0016] By fixing the first longitudinal support rod to the longitudinal rod, the higher stiffness of the longitudinal rod can be used to further enhance its rigidity. Because the temperature control probe obstructs the airflow from the air conditioner, the load on the mounting components is more significant. Similarly, the first longitudinal support rod increases the rigidity of the longitudinal rod at the mounting component, thus ensuring the installation stability of the temperature control probe.

[0017] In a preferred embodiment, a reinforcing rib is provided between the first longitudinal support rod and the longitudinal rod.

[0018] By adding reinforcing ribs, the stiffness of the first longitudinal support rod in resisting the torque generated at the root of the first longitudinal support rod relative to the horizontal force can be improved, thereby effectively reducing or even eliminating the swaying of the mounting components and temperature control probe under the action of airflow.

[0019] In a preferred embodiment, the upper end of the longitudinal support rod is fixedly connected to an upper plate, and the upper plate has a notch, which corresponds vertically to the area between the longitudinal support rod, the support plate, and the pressure rod.

[0020] By setting a vertical notch on the upper plate corresponding to the area between the longitudinal support rod, the support flat rod, and the pressure rod, the temperature control probe cable can pass through this area and connect to the electrical control box. Setting the notch can reduce the degree of bending of the cable at this point, thereby helping to improve the cable's lifespan.

[0021] The second objective of this invention is to provide an indoor air conditioning unit to solve the technical problem of unreasonable cable arrangement.

[0022] The air conditioner indoor unit provided by the present invention includes the above-mentioned evaporator bracket assembly.

[0023] By incorporating the aforementioned evaporator bracket assembly into the air conditioner, the air conditioner thereby possesses all the advantages of the aforementioned evaporator bracket assembly, which will not be elaborated upon here.

[0024] The third objective of this invention is to provide an air conditioner that solves the technical problem of unreasonable cable arrangement.

[0025] The air conditioner provided by the present invention includes the above-mentioned indoor air conditioner unit.

[0026] By installing the aforementioned indoor unit in the air conditioner, the air conditioner will have all the advantages of the aforementioned indoor unit, which will not be elaborated here. Attached Figure Description

[0036] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0037] Example 1:

[0038] Figure 1 This is a schematic diagram of the structure of the evaporator support assembly provided in an embodiment of the present invention; Figure 4 This is a schematic diagram illustrating the structure of the evaporator bracket assembly provided in an embodiment of the present invention applied to an air conditioner indoor unit. Figure 1 and Figure 4 As shown, the evaporator support assembly provided in this embodiment of the invention includes a connecting bracket 100 and a temperature control probe (not shown in the figure). The connecting bracket 100 has an air inlet configured to allow airflow passing through the evaporator to enter. The temperature control probe is mounted on the connecting bracket 100 and is located to the right of the air inlet center position in the air inlet of the connecting bracket 100.

[0039] The evaporator support assembly, in addition to the connecting bracket 100, includes an upper bracket 210 fixedly connected to the top of the connecting bracket 100, and a lower bracket 220 fixedly connected to the bottom of the connecting bracket 100. The upper bracket 210 is equipped with a motor 310, which is connected to the fan blades 320 to drive the fan blades 320 to rotate, generating airflow to exchange heat with the evaporator, and then delivering the heat-exchanged air to the indoor unit of the cabinet air conditioner through the air inlet. Figure 1 In the diagram, viewed from the rear of the indoor unit of a cabinet air conditioner, the temperature control probe is located on the right side of the center of the air inlet, as shown in the image. Therefore, when viewed from the rear of the indoor unit, the temperature control probe is located on the right side of the air intake area. Conversely, if viewed from the front of the indoor unit, it is located on the left side of the center of the air inlet, and on the left side of the air intake area. This description is based on the view from the rear of the indoor unit.

[0040] By placing the temperature control probe on the left side of the air inlet of the connecting bracket 100 in the direction of airflow, the temperature control probe and the low-voltage cable can be placed on the same side, reducing electromagnetic interference between high-voltage and low-voltage cables. This also reduces cable length, saving on air conditioner manufacturing costs. Furthermore, it eliminates the need for cable trays connecting the temperature control probe and the electrical control box, reducing damage to the structural strength of the evaporator bracket assembly.

[0041] Experiments have shown that, based on observation from the outside of the indoor unit of a cabinet air conditioner, the air velocity at the air inlet is lowest in the middle of the inlet's width. The air velocity on the left side along the air intake direction is approximately 5% to 15% higher than in the middle, while the air velocity on the right side is approximately 45% to 65% higher than in the middle. Therefore, placing the temperature control probe on this side allows for the measurement of a faster air velocity, thereby improving measurement accuracy.

[0042] Figure 2 for Figure 1 A partial enlarged view of the mounting components in the evaporator bracket assembly shown; Figure 3 This is a schematic diagram of the mounting components in the evaporator support assembly provided in an embodiment of the present invention, viewed from another angle. (See diagram below.) Figure 2 and Figure 3 As shown, preferably, the connecting bracket 100 is provided with an installation component 110. The installation component 110 includes a longitudinal support rod, a pressure rod 113 and a support flat rod 114. The support flat rod 114 connects two vertically extending longitudinal support rods, and the pressure rod 113 presses the temperature control probe against the support flat rod 114.

[0043] By setting up a pressure rod 113, the temperature control probe is pressed against the vertically extending longitudinal support rod and the support flat rod 114 connecting the two longitudinal support rods. This pressing method not only ensures the stability of the temperature control probe during normal use, but also utilizes the elasticity of the pressure rod 113. Similarly, when disassembly or assembly is required, the pressure rod 113 can also deform in the direction away from the support flat rod 114, which also facilitates disassembly or assembly. Moreover, in the area outside the support flat rod 114, more of the surface around the temperature control probe comes into contact with the flowing air, allowing it to more fully sense the air temperature, thereby improving the accuracy of temperature measurement.

[0044] like Figure 2 and Figure 3 As shown, preferably, the mounting assembly 110 includes multiple horizontal bars arranged in a vertical direction.

[0045] The longitudinal support rods include a second longitudinal support rod 112 and a first longitudinal support rod 111 (described below). A support flat rod 114 is provided between the first longitudinal support rod 111 and the second longitudinal support rod 112. Multiple support flat rods 114 and the two longitudinal support rods form an overall shape resembling a ladder. Specifically, each flat rod can be horizontally arranged to connect the first longitudinal support rod 111 and the second longitudinal support rod 112.

[0046] By setting up multiple horizontal bars arranged vertically, the temperature control probe can be evenly supported outwards. Alternatively, two longitudinal support bars can be connected to prevent bending in the middle of the longitudinal support bars, thereby improving the installation stability of the temperature control probe.

[0047] like Figure 2 and Figure 3 As shown, preferably, there are two pressure rods 113, which abut against the upper and lower parts of the temperature control probe respectively.

[0048] By using the pressure rod 113 to abut against the temperature control probe from the top and middle, the temperature control probe can be firmly fixed on the mounting assembly 110, preventing the temperature control probe from swinging under the action of airflow and thus becoming loose.

[0049] like Figure 2 As shown, preferably, the connecting bracket 100 includes a longitudinal rod 101, and the longitudinal support rod includes a first longitudinal support rod 111, which is fixedly connected to the longitudinal rod 101. Specifically, the length direction of the first longitudinal support rod 111 is consistent with the length direction of the longitudinal rod 101, and it is connected to the longitudinal rod 101 along its entire length. The width direction of the first longitudinal support rod 111 forms an angle of 60°-90° with the width direction of the longitudinal rod 101.

[0050] By fixing the first longitudinal support rod 111 to the longitudinal rod 101, the greater stiffness of the longitudinal rod 101 can be used to further enhance the stiffness of the first longitudinal support rod 111. Because the temperature control probe obstructs the air intake of the air conditioner, the load on the mounting assembly 110 is also more significant. Similarly, the first longitudinal support rod 111 increases the stiffness of the longitudinal rod 101 at the mounting assembly 110, thereby ensuring the installation stability of the temperature control probe.

[0051] like Figure 2 and Figure 3 As shown, preferably, the pressure rod 113 is J-shaped, and the top ends of the J-shape of the two pressure rods 113 are fixedly connected to a longitudinal support rod, with the free end of the bent part of the J-shape of the pressure rod 113 facing the other longitudinal support rod.

[0052] The plane containing the J-shape can still be horizontal. However, this J-shape is not exactly the same as the letter J, consisting of a straight line and an arc; it merely resembles the letter J. The portion of the pressure rod 113 fixedly connected to the second longitudinal support rod 112 is inclined to the support rod 114. The middle part of the pressure rod 113 can be parallel to the support rod 114, while the free end of the pressure rod 113 faces the first longitudinal support rod 111. That is, the pressure rod 113 itself can form an opening towards the support rod 114.

[0053] The use of a J-shaped pressure rod 113 provides significant elasticity. When the temperature control probe is inserted, the process of the probe being pushed in increases the distance between the free end of the bent portion of the pressure rod 113 and the other longitudinal support rod. After the temperature control probe reaches its designated position, the pressure rod 113 springs back, securing the probe and facilitating its insertion and fixation. The process of disassembling the temperature control probe is the reverse of the above and will not be described further.

[0054] like Figure 2 As shown, preferably, a reinforcing rib 102 is provided between the first longitudinal support rod 111 and the longitudinal rod 101.

[0055] By setting the reinforcing rib 102, the stiffness of the first longitudinal support rod 111 in resisting the torque generated at the root of the first longitudinal support rod 111 by the force acting along the circumference of the evaporator can be improved, thereby effectively reducing or even eliminating the shaking of the mounting assembly 110 and the temperature control probe under the action of airflow.

[0056] like Figure 2 and Figure 3As shown, preferably, the upper end of the longitudinal support rod is fixedly connected to the upper plate 120, and the upper plate 120 has a notch 121. The notch 121 corresponds in the vertical direction to the area between the longitudinal support rod, the support flat rod 114 and the pressure rod 113.

[0057] By setting a notch 121 on the upper plate 120 corresponding to the area between the longitudinal support rod, the support flat rod 114 and the pressure rod 113 in the vertical direction, the temperature control probe cable can pass through here and connect to the electrical control box. Setting the notch 121 can reduce the degree of bending of the cable at this point, thereby helping to improve the cable life.
