Technical Field

[0001] The utility model relates to the technical field of heat pump units, in particular to a heat pump unit with an auxiliary transport structure. Background Art

[0002] A heat pump unit is a system used for heating and cooling. The heat pump unit uses the principle of heat energy transfer to absorb heat from one heat source and then release it to another heat source. The heat pump unit is mainly composed of components such as a compressor, an evaporator, a condenser, an expansion valve, and a controller. In winter or cold environments, the heat pump unit can absorb low-temperature heat from the outdoor environment, compress it, and release it to the room after heating, thereby providing comfortable indoor heating. In summer or hot environments, the heat pump unit can absorb heat from the room and release it to the outside, thereby reducing the indoor temperature.

[0003] In cooling mode, the heat pump unit absorbs heat from indoors and releases it to outdoors, thereby lowering the indoor temperature. In heating mode, it absorbs heat from outdoors and releases it to indoors, thereby raising the indoor temperature. Heat pump units are generally large in size and have a certain weight. When workers move the heat pump unit by manpower, they need to continuously expend more physical strength, which makes the workers' carrying burden heavy and it is difficult to move the heat pump unit easily. Therefore, we propose a heat pump unit with an auxiliary carrying structure. Utility Model Content

[0010] Preferably, the screw rod, the bevel gear, the double bevel gear disc frame and the knob are respectively movably connected to the bottom plate through bearings.

[0011] Preferably, fixed pipes are respectively connected to one side of the heat pump unit main body close to the high-pressure pressure gauge and one side close to the low-pressure pressure gauge.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-3 and Figure 6, the present utility model provides a technical solution: a heat pump unit with an auxiliary handling structure, including a heat pump unit main body 1 and a fan top cover 101. The fan top cover 101 is fixed on the upper side of the heat pump unit main body 1, and a high-pressure pressure gauge 102 and a low-pressure pressure gauge 103 are sequentially installed on the surface of the heat pump unit main body 1. One side of the heat pump unit main body 1 is sequentially fixed with a hot water outlet pipe 104 and a cold water outlet pipe 105. The bottom plate 106 is fixed on the lower side of the heat pump unit main body 1. Handles 2 are respectively fixed on both sides of the heat pump unit main body 1. A storage groove 201 is opened on the lower side of the bottom plate 106, and a support rod 202 is arranged inside the storage groove 201. One end of the support rod 202 is slidably installed with a roller 203. The end of the support rod 202 far from the roller 203 is fixed with a toothed plate 204, and the toothed plate 204 is movably connected to the bottom plate 106 through a bearing. The toothed plate 204 is butted against one side of a toothed block 205. A first chute 2051 is opened on the side of the bottom plate 106 close to the toothed block 205, and the first chute 2051 is slidably butted against the toothed block 205. The end of the toothed block 205 far from the toothed plate 204 is fixed with a docking rod 206. A second chute 2061 is opened on the side of the bottom plate 106 close to the docking rod 206, and the docking rod 206 is slidably butted against the second chute 2061. A screw rod 207 penetrates through the inside of the docking rod 206. The end of the screw rod 207 far from the docking rod 206 is fixed with a bevel gear 208, and the bevel gear 208 is butted against a double bevel gear disc frame 209. A knob 210 is fixed at one end of the double bevel gear disc frame 209. The screw rod 207, the bevel gear 208, the double bevel gear disc frame 209 and the knob 210 are respectively movably connected to the bottom plate 106 through bearings. The toothed plate 204 and the toothed block 205 are in meshing connection. The toothed block 205 matches the first chute 2051. The docking rod 206 matches the second chute 2061. The cross section of the docking rod 206 is rectangular. The docking rod 206 is in threaded connection with the screw rod 207, and the thread directions of two adjacent screw rods 207 are opposite. The bevel gear 208 and the bevel gear disc of the double bevel gear disc frame 209 are in meshing connection.

[0027] During specific implementation, according to Figures 1-3 and Figure 6, in the cooling mode, the heat pump unit absorbs heat from the indoor and releases it outdoors, thereby reducing the indoor temperature. In the heating mode, it absorbs heat from the outdoor and releases it indoors, thereby increasing the indoor temperature. When the staff manually move the heat pump unit, first lift the heat pump unit main body 1 through the handle 2. At this time, rotate the knob 210, so that the knob 210 drives the double conical gear rack 209 to rotate. The bevel gear 208 is in meshing connection with the conical gear disk of the double conical gear rack 209, so that the double conical gear rack 209 drives the two bevel gears 208 to rotate at the same time, and the two bevel gears 208 rotate in opposite directions. At this time, the bevel gears 208 drive the screws 207 to rotate respectively. Through the docking rod 206 matching with the second chute 2061, and the cross section of the docking rod 206 is rectangular, so that the docking rod 206 does not rotate with the screw 207. Then, through the docking rod 206 being in threaded connection with the screw 207, and the thread directions of two adjacent screws 207 being in opposite directions, the two docking rods 206 approach or move away from each other. When the two docking rods 206 approach each other, the docking rod 206 drives the tooth block 205 away from the tooth plate 204, so that the tooth plate 204 is disengaged from the meshing connection with the tooth block 205. At this time, the tooth plate 204 is released from the limit of the tooth block 205, and the roller 203 drives the support rod 202 to rotate under the action of its own gravity. At this time, the roller 203 rotates and moves down to fit with the ground. Then rotate the knob 210 in the reverse direction again, so that the two docking rods 206 move away from each other, so that the docking rod 206 pushes the tooth block 205 to mesh with the tooth plate 204 again, so that the tooth block 205 restricts the tooth plate 204 from rotating, and the roller 203 keeps moving down and fits with the ground. At this time, release the handle 2, and the roller 203 can lift the heat pump unit main body 1 through the support rod 202, so that the staff can push the heat pump unit main body 1 to move, making it easy for the staff to move the heat pump unit easily.

[0028] Please refer to Figure 1 , Figure 4 and Figure 5, on one side of the main body 1 of the heat pump unit close to the high-pressure pressure gauge 102 and on one side close to the low-pressure pressure gauge 103, fixed pipes 3 are respectively connected. One end of a connecting spring 301 is fixed inside the fixed pipe 3, and the other end of the connecting spring 301 is fixed to a ring plate 302. The ring plate 302 is slidably butted with the fixed pipe 3, and a slider 303 is fixed to the outside of the ring plate 302. A third chute 304 is formed on one side of the fixed pipe 3 close to the slider 303, and the slider 303 is slidably butted with the third chute 304. One end of the fixed pipe 3 is slidably penetrated by a connecting pipe 305, and one side of the connecting pipe 305 is fixed to the ring plate 302. The end of the connecting pipe 305 away from the ring plate 302 is butted with a butting pipe 306, and a disc 307 is fixed to the inner side of the butting pipe 306. The fixed pipe 3 matches the ring plate 302, the slider 303 matches the third chute 304, the connecting pipe 305 and the butting pipe 306 are threadedly connected, and the disc 307 is made of transparent plastic material.

[0029] During specific implementation, according to Figure 1 , Figure 4 and Figure 5 , when the heat pump unit is put into use, the butting pipe 306 and the connecting pipe 305 are rotationally butted. Since the slider 303 matches the third chute 304, the connecting pipe 305 will not rotate following the butting pipe 306. Then, because the connecting pipe 305 and the butting pipe 306 are threadedly connected, the connecting pipe 305 and the butting pipe 306 are restricted together, making the disc 307 respectively restricted outside the high-pressure pressure gauge 102 and the low-pressure pressure gauge 103. Since the disc 307 is made of transparent plastic material, the staff can respectively view the high-pressure pressure gauge 102 and the low-pressure pressure gauge 103 through the disc 307. When the disc 307 is subjected to an external impact, the disc 307 forces the connecting pipe 305, causing the connecting pipe 305 to drive the ring plate 302 to slide along the fixed pipe 3. Due to the matching between the fixed pipe 3 and the ring plate 302, the ring plate 302 is not easily offset during sliding, enabling the ring plate 302 to stably push and contract the connecting spring 301, so that the external force received by the disc 307 can be buffered, enabling the disc 307 to protect the high-pressure pressure gauge 102 and the low-pressure pressure gauge 103, preventing the high-pressure pressure gauge 102 and the low-pressure pressure gauge 103 from being damaged, and enabling the heat pump unit to protect the instruments.

[0030] In summary, in the cooling mode, the heat pump unit absorbs heat from the indoor environment and releases it outdoors, thereby reducing the indoor temperature. In the heating mode, it absorbs heat from the outdoors and releases it indoors, thereby increasing the indoor temperature. Rotate the knob 210 to disengage the toothed plate 204 from the limit of the toothed block 205, causing the roller 203 to rotate downward and fit with the ground. Rotate the knob 210 in the reverse direction, so that the toothed block 205 can limit the rotation of the toothed plate 204, making the roller 203 remain in the downward position and fit with the ground. At this time, the roller 203 can lift the main body 1 of the heat pump unit through the support rod 202, enabling the staff to push the main body 1 of the heat pump unit to move, making it easy for the staff to move the heat pump unit. Restrict the discs 307 outside the high-pressure pressure gauge 102 and the low-pressure pressure gauge 103 respectively, so that the discs 307 can protect the high-pressure pressure gauge 102 and the low-pressure pressure gauge 103, enabling the heat pump unit to protect the instruments. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
