[0027] The embodiment of the present application provides a temperature sensing bag support for fixing a temperature sensing bag, the temperature sensing bag comprising a temperature sensing probe and a temperature sensing wire connected with the temperature sensing probe, and the temperature sensing probe is capable of detecting the temperature of the surrounding environment.
[0028] As shown in Figure 1 and Figure 2 The temperature sensing bag support 100 provided by the embodiment of the present application comprises a main body part 110, a positioning part 120 and an adjusting part 130, the positioning part 120 is arranged on the main body part 110, the positioning part 120 is provided with a wire passing groove 121 penetrating through the positioning part 120 along a first direction, the wire passing groove 121 is used for clamping the temperature sensing wire 12 of the temperature sensing bag and accommodating the temperature sensing probe 11 of the temperature sensing bag; one end of the adjusting part 130 is connected with one end of the positioning part 120 along the first direction, and the adjusting part 130 has an adjusting surface 131 facing the inside of the wire passing groove 121, and the adjusting surface 131 is used for adjusting the position of the temperature sensing probe 11.
[0029] The temperature sensing bag support 100 and the air conditioner provided by the embodiment of the present application, by arranging the wire passing groove 121 penetrating through the positioning part 120 along the first direction on the positioning part 120, and connecting one end of the adjusting part 130 with one end of the positioning part 120 along the first direction, and the adjusting part 130 has the adjusting surface 131 facing the inside of the wire passing groove 121 and used for adjusting the position of the temperature sensing probe 11, so that when the temperature sensing bag is installed on the temperature sensing bag support 100, the temperature sensing wire 12 of the temperature sensing bag can be clamped and the temperature sensing probe 11 of the temperature sensing bag can be accommodated through the wire passing groove 121, and the position of the temperature sensing probe 11 can be adjusted through the adjusting surface 131, so that the position of the temperature sensing probe 11 on the temperature sensing bag support 100 can be well controlled, and thus the temperature detection accuracy of the temperature sensing probe 11 can be ensured.
[0030] Specifically, the width of the wire passing groove 121 is smaller than the outer diameter of the temperature sensing wire 12, when the temperature sensing bag is installed on the temperature sensing bag support 100, the temperature sensing wire 12 is in interference fit with the wire passing groove 121 to clamp the temperature sensing wire 12 in the wire passing groove 121, so that the temperature sensing wire 12 can be firmly and reliably fixed on the temperature sensing bag support 100; the temperature sensing probe 11 is arranged on the adjusting surface 131 of the adjusting part 130, and the position of the temperature sensing probe 11 in the wire passing groove 121 is adjusted through the adjusting surface 131, so that the position of the temperature sensing probe 11 on the temperature sensing bag support 100 can be controlled, and thus the temperature sensing probe 11 can maintain an appropriate distance from the heat exchanger 200 of the air conditioner, so as to ensure the temperature detection accuracy of the temperature sensing probe 11.
[0031] In some embodiments of this application, the main body 110 has a first side for mounting to an external device (e.g., the heat exchanger 200 of an air conditioner) and a second side opposite to the first side. An adjusting surface 131 abuts against the side of the temperature sensor 11 to allow the temperature sensor 11 to extend towards the second side. This arrangement allows the adjusting surface 131 to effectively support the extension of the temperature sensor 11, thereby effectively controlling the appropriate distance between the temperature sensor 11 and the heat exchanger 200 of the air conditioner to ensure the accuracy of temperature detection by the temperature sensor 11.
[0032] Optionally, the end of the adjusting surface 131 away from the positioning part 120 is inclined toward the second side of the main body 110. This arrangement allows the temperature probe 11 to extend a relatively longer distance toward the second side of the main body 110, thereby further improving the temperature measurement accuracy of the temperature probe 11.
[0033] Optionally, when the end away from the positioning part 120 is inclined towards the second side of the main body 110, the angle between the adjusting surface 131 and the center line of the wire groove 121 is 30° to 60°. For example, the angle between the adjusting surface 131 and the center line of the wire groove 121 can be 30°, 35°, 40°, 45°, 50°, 55° or 60°, etc., and can be set according to actual needs.
[0034] In some embodiments of this application, the main body 110 is provided with a positioning groove 124 at one end along the first direction. The positioning groove 124 is used to position the temperature sensing wire 12 of the temperature sensing bulb. By providing the positioning groove 124, it is convenient to organize and position the temperature sensing wire 12, and avoid the temperature sensing wire 12 from becoming messy.
[0035] Optional, such as Figure 2 As shown, the first direction can be Figure 2 In the vertical direction, the positioning groove 124 is set at the upper end of the main body 110 along the vertical direction, and the adjustment part 130 is set at the lower end of the positioning part 120 along the vertical direction. When it is necessary to fix the temperature sensing wire 12 of the temperature sensing bag to the temperature sensing bag bracket 100, the temperature sensing wire 12 can be routed from inside the device to the temperature sensing bag bracket 100, and then run out along the positioning groove 124 (that is, the temperature sensing wire 12 is inserted into the positioning groove 124), and then run into the wire guide groove 121, and the temperature sensing wire 12 is clamped by the wire guide groove 121.
[0036] In some embodiments of this application, the positioning part 120 includes a first positioning part 122 and a second positioning part 123. The first positioning part 122 and the second positioning part 123 are spaced apart along a first direction (i.e., the first positioning part 122 and the second positioning part 123 are spaced apart from each other in the first direction). The wire passage groove 121 includes a first wire passage groove 1221 that passes through the first positioning part 122 along the first direction and a second wire passage groove 1231 that passes through the second positioning part 123 along the first direction. The openings of the first wire passage groove 1221 and the second wire passage groove 1231 are not oriented in the same direction. By securing the temperature sensing wire 12 in the wire passage groove 121 and by utilizing the fact that the openings of the first wire passage groove 1221 and the second wire passage groove 1231 are not oriented in the same direction, this application can further securely fix the temperature sensing wire 12, making it less prone to loosening and improving the fixing strength of the temperature sensing wire 12.
[0037] In some embodiments of this application, the temperature sensor bracket 100 further includes a fixing part 140, which is disposed on the main body 110. The fixing part 140 is provided with a snap-fit structure 141 for snapping the fixing part 140 onto an external device (e.g., the heat exchanger end plate 210 of an air conditioner). By providing the snap-fit structure 141, the fixing part 140 can be quickly installed onto the external device without the need for screw connection, simplifying the operation and thus improving assembly efficiency.
[0038] Specifically, the external device is provided with a snap-fit part 211. One of the snap-fit part 211 and the snap-fit structure 141 is a snap hole, and the other is a snap fastener. The snap fastener engages with the snap hole to snap the fixing part 140 onto the external device. For example, the snap-fit part 211 on the external device can be a snap fastener, and the snap-fit structure 141 on the fixing part 140 can be a snap hole (e.g.,...). Figure 1 As shown, the buckle on the external device engages with the buckle hole on the fixing part 140, thereby securing the fixing part 140 to the external device; or, the buckle 211 on the external device may be a buckle hole, and the buckle structure 141 on the fixing part 140 may be a buckle, with the buckle on the fixing part 140 engaging with the buckle hole on the external device, thereby securing the fixing part 140 to the external device.
[0039] Optionally, the temperature sensor bracket 100 further includes a support portion 150, which is disposed on the same side of the main body 110 as the fixing portion 140. The external device has a front and a side adjacent to the front. The fixing portion 140 is snapped onto the front of the external device, and the support portion 150 is used to support the side of the external device. By providing the support portion 150, when the fixing portion 140 is snapped onto the front of the external device, the support portion 150 supports the side of the external device, thereby ensuring that the temperature sensor bracket 100 does not tilt due to gravity, thus improving the stability of the temperature sensor bracket 100.
[0040] The embodiments of the present application also provide an air conditioner, as shown in the drawings. Figures 3-6 The air conditioner comprises a heat exchanger 200 and a temperature bulb bracket 100, the specific structure of the temperature bulb bracket 100 is referred to the above embodiments, and the heat exchanger 200 comprises a heat exchanger end plate 210, and the temperature bulb bracket 100 is installed on the heat exchanger end plate 210. Since all the technical solutions of the above embodiments are adopted in the air conditioner, all the beneficial effects brought by the technical solutions of the above embodiments are at least achieved, and thus will not be repeated here.
[0041] Optionally, when the temperature bulb bracket 100 comprises the fixing portion 140, the fixing portion 140 is clamped on the heat exchanger end plate 210 through the clamping structure 141 thereon, thereby solving the problem of hanging in the pre-assembly process of the temperature bulb bracket 100. Specifically, the clamping portion 211 is arranged on the heat exchanger end plate 210, one of the clamping portion 211 and the clamping structure 141 is a clamping hole, and the other is a clamping buckle, the clamping buckle is clamped and matched with the clamping hole, thereby realizing the clamping of the fixing portion 140 on the heat exchanger end plate 210.
[0042] For example, the clamping portion 211 on the heat exchanger end plate 210 can be arranged as a clamping hole (as shown in the drawings), and the clamping structure 141 on the fixing portion 140 is arranged as a clamping buckle (as shown in the drawings), the clamping buckle on the fixing portion 140 is clamped into the clamping hole on the heat exchanger end plate 210, thereby realizing the clamping of the fixing portion 140 on the heat exchanger end plate 210; or the clamping portion 211 on the heat exchanger end plate 210 can be arranged as a clamping buckle, and the clamping structure 141 on the fixing portion 140 is arranged as a clamping hole, the clamping buckle on the heat exchanger end plate 210 is clamped into the clamping hole on the fixing portion 140, thereby realizing the clamping of the fixing portion 140 on the heat exchanger end plate 210. Figure 1 Figure 4
[0043] In some embodiments of the present application, the air conditioner further comprises a shell, and the heat exchanger 200 and the temperature bulb bracket 100 are arranged in the shell; the shell comprises a side plate 300, the side plate 300 is connected with the end plate of the heat exchanger 200 and presses the temperature bulb bracket 100. The side plate 300 of the shell of the air conditioner is connected with the heat exchanger end plate 210, and the side plate 300 presses the temperature bulb bracket 100, thereby realizing the firm fixation of the temperature bulb bracket 100 on the heat exchanger end plate 210, and the temperature bulb bracket 100 can be effectively prevented from accidentally falling off in the use process.
[0044] Specifically, when the temperature bulb bracket 100 comprises the fixing portion 140, the side plate 300 presses the fixing portion 140 of the temperature bulb bracket 100, that is, the fixing portion 140 of the temperature bulb bracket 100 is located between the side plate 300 of the shell of the air conditioner and the heat exchanger end plate 210, and the side plate 300 presses and fixes the fixing portion 140 on the heat exchanger end plate 210.
[0045] Optionally, the air conditioner comprises an air conditioner outdoor unit installed outdoors, the side plate 300 is a side plate 300 of a housing of the air conditioner outdoor unit, the heat exchanger 200 is an outdoor heat exchanger 200 of the air conditioner outdoor unit, the heat exchanger end plate 210 is an end plate of the outdoor heat exchanger 200, and the temperature bulb bracket 100 is installed on the end plate of the outdoor heat exchanger 200 to fix the temperature bulb, and the temperature bulb is used to detect the temperature of the outdoor environment.
[0046] In combination Figures 2-6 As shown in the figure, the assembly process of the temperature bulb and the temperature bulb bracket 100 is as follows:
[0047] First, the fixing part 140 of the temperature bulb bracket 100 is clamped on the front surface of the heat exchanger end plate 210 through the clamping structure 141, and at the same time, the supporting part 150 of the temperature bulb bracket 100 is supported on the side surface of the heat exchanger end plate 210, realizing the pre-assembly of the temperature bulb bracket 100. Through the clamping cooperation of the fixing part 140 and the heat exchanger end plate 210, and the interaction of the supporting part 150 and the end part of the heat exchanger 200, the temperature bulb bracket 100 can be basically kept stable and not shaken. Then, the temperature sensing wire 12 of the temperature bulb is led from the inside of the air conditioner unit to the temperature bulb bracket 100, and the temperature sensing wire 12 is led out along the positioning groove 124 of the temperature bulb bracket 100, and is inclined downward into the wire passing groove 121 of the temperature bulb bracket 100, so that the temperature sensing wire 12 is clamped in the wire passing groove 121. Then, the temperature sensing probe 11 of the temperature bulb is placed on the adjusting surface 131 of the adjusting part 130 to adjust the distance between the temperature sensing probe 11 and the heat exchanger 200, and ensure the temperature detection accuracy. Finally, after the whole machine is assembled, the fixing part 140 of the temperature bulb bracket 100 is pressed tightly by the side plate 300 of the air conditioner housing. From now on, the temperature bulb bracket 100 does not need to be fixed by a screw from beginning to end, which solves the problem of hanging in the pre-assembly process of the temperature bulb bracket 100, and also solves the problems of firm fixation of the temperature bulb and accuracy of temperature detection.
