Detailed Implementation
[0022] The present invention will now be further described with reference to the accompanying drawings.
[0023] This utility model provides a flexible and easy-to-use heater, such as... Figure 3 As shown, it includes host 10, such as Figure 8 and Figure 9 As shown, the main unit 10 includes a casing 1, a centrifugal fan 2, and an electric heater 4. The centrifugal fan 2 and the electric heater 4 are disposed inside the casing 1, as shown. Figure 1 As shown, an air outlet 111 is provided on the lower front side of the casing 1. Specifically, as... Figure 8 and Figure 9 As shown, the impeller of the centrifugal fan 2 rotates along the front-to-back direction. The exhaust port of the centrifugal fan 2's volute is downward-facing, and a bend 3 is connected to the exhaust port. An electric heater 4 is located inside the front end of the bend 3, corresponding to the rear side of the exhaust port 111. Therefore, when the centrifugal fan 2 operates, it outputs airflow downwards. The airflow is then guided forward by the bend 3, passes through the electric heater 4, and is then discharged forward through the exhaust port 111. Figure 8 As shown, when the impeller of the centrifugal fan 2 has a large diameter, and because a volute needs to be installed on the outside of the impeller, if the rotation axis of the impeller of the centrifugal fan 2 is set along the vertical or horizontal direction, the main unit 10 will have a large external dimension in the front-back direction. Therefore, setting the rotation axis of the impeller of the centrifugal fan 2 along the front-back direction helps to reduce the external dimension of the main unit 10 in the front-back direction, so as to facilitate the wall-mounted use of the heater and avoid the heater protruding forward from the wall in a large size when it is hung on the wall, which is relatively beneficial to reduce the space occupied by the heater.
[0024] like Figures 1 to 3As shown, the heater of this utility model also includes a stand 7 and a mounting plate 8. The stand 7 includes a horizontal tube section 71, a vertical tube section 72, and a frame tube section 73 for contacting the ground. The upper end of the vertical tube section 72 is fixedly connected to one end of the horizontal tube section 71, and the lower end of the vertical tube section 72 is fixedly connected to the frame tube section 73. The horizontal tube section 71 is detachably installed in the lower rear part of the housing 1. The horizontal tube section 71 extends in the left and right direction. More specifically, the horizontal tube section 71, the vertical tube section 72, and the frame tube section 73 can be an integral structure, that is, the horizontal tube section 71, the vertical tube section 72, and the frame tube section 73 can be formed by bending the same round tube using a tube bending machine. From a top view angle, the frame tube section 73 is roughly bent into a rectangle (missing one side). Therefore, when the frame tube section 73 is placed flat on the ground, the stand 7 is not easily tilted or swayed back and forth or left and right. Figure 7 As shown, the mounting plate 8 has a mounting groove 801 for connecting wall-mounted nails. Specifically, the mounting plate 8 also has a clearance hole 8011, which connects to the corresponding mounting groove 801. Thus, the head of the wall-mounted nail can pass through the clearance hole 8011 and slide relative to it, causing the nail to move relative to the mounting groove 801. The width of the mounting groove 801 is adapted to the nail, so the head of the nail cannot pass through the mounting groove 801, thereby preventing the mounting plate 8 from disengaging forward from the nail. Figure 7 As shown, there are two hanging slots 801, arranged side-by-side. Figure 2 As shown, the mounting plate 8 is located at the upper rear part of the housing 1, and since the mounting horizontal tube 71 is detachably installed at the lower rear part of the housing 1, the rear space of the main unit 10 is made reasonable use.
[0025] When the heater of this utility model needs to be wall-mounted, first disassemble the stand 7, and then connect the hanging slot 801 to the wall-mounted nails. When the heater of this utility model needs to be floor-mounted, remove the main unit 10 from the wall, then install the horizontal pipe 71 onto the housing 1, and then place the stand 7 on the ground. Because of the vertical pipe 72, the height of the main unit 10 is increased, meaning the air outlet 111 is positioned higher. Since the stand 7 can be made of bent steel pipe, its manufacturing cost is low. As can be seen from the above, the heater of this utility model can easily switch between wall-mounted and floor-mounted installation, thus offering good flexibility in use.
[0026] Furthermore, the rear of the housing 1 is provided with a clamping plate 122, such as... Figure 5 As shown, the clamping plate 122 has a positioning groove 1221, which extends in the left-right direction, as... Figure 2As shown, a cover 13 is installed on the rear side of the clamping plate 122. The cover 13 can be connected to the clamping plate 122 by corresponding screws. Specifically, the screws pass through the cover 13 and the clamping plate 122 from back to front, and the screws are screwed into the housing 1, thereby reliably fixing the cover 13 and the clamping plate 122 to the housing 1. Figure 6 As shown, a clamping groove 1301 is formed at the front of the clamping cover 13, and a grid-like weight-reducing hollow structure is formed at the front of the clamping cover 13, such as... Figure 2 Combination Figure 4 As shown, the mounting horizontal tube 71 is adapted to be disposed between the positioning groove 1221 and the clamping groove 1301. That is to say, the clamping plate 122 and the clamping cover 13 clamp the mounting horizontal tube 71. The mounting structure of the mounting horizontal tube 71 and the housing 1 is relatively simple, so that the mounting horizontal tube 71 can be separated from the housing 1 after the clamping cover 13 is removed.
[0027] Furthermore, such as Figure 3 As shown, a positioning hole 711 is formed on the mounting horizontal tube section 71, such as... Figure 6 As shown, a locating pin 131 is formed on the cover 13, such as Figure 4 As shown, the positioning pin 131 is adapted to the insertion positioning hole 711, thus the positioning pin 131 prevents the horizontal tube section 71 from shifting left and right and rotating relative to the housing 1. The positioning pin 131 can extend in the front-back direction, thus preventing the horizontal tube section 71 from shifting up and down relative to the housing 1; as shown Figure 3 As shown, the number of positioning holes 711 is set to two, and the two positioning holes 711 are arranged on the left and right sides, as shown. Figure 4 and Figure 5 As shown, pin holes 1222 can also be formed on the clamping plate 122, and the front end of the positioning pin 131 can be adapted to be inserted into the corresponding pin hole 1222.
[0028] Furthermore, such as Figure 3 As shown, a notch 712 is formed at the other end corresponding to the mounting horizontal tube 71, as... Figure 5 As shown, a front locking block 1223 is formed within the positioning groove 1221, such as... Figure 6 As shown, a rear locking block 132 is formed at the front of the cover 13, as... Figure 4As shown, the rear locking block 132 and the front locking block 1223 are adapted to be disposed within the notch 712. That is to say, the front locking block 1223 engages with the front part of the mounting horizontal tube section 71, and the rear locking block 132 engages with the rear part of the mounting horizontal tube section 71, thereby further preventing the mounting horizontal tube section 71 from rotating relative to the housing 1. During the process of installing and connecting the mounting horizontal tube section 71 to the housing 1, first insert the positioning pin 131 into the positioning hole 711 by hand, and at the same time insert the rear locking block 132 into the notch 712. Then, cover the front side of the mounting horizontal tube section 71 with the clamping plate 122, and at the same time insert the front locking block 1223 into the notch 712. Move the clamping plate 122 forward to the housing 1, and pass the screw from back to front through the clamping cover 13 and the clamping plate 122, so that the screw is screwed into the housing 1.
[0029] Furthermore, such as Figure 5 As shown, a hanging cap 123 is formed on the upper rear part of the housing 1, and a latch 1231 is formed on the rear side of the hanging cap 123. The upper end of the latch 1231 is closed, and the lower end of the latch 1231 passes through the hanging cap 123. Figure 7 As shown, a fastening post 81 is formed on the front side of the mounting plate 8. In other words, the fastening post 81 protrudes forward relative to the mounting plate 8. The fastening post 81 is a square post, and slots 811 are formed on the left and right sides of the fastening post 81. The slots 811 extend in the vertical direction, as shown. Figure 2 , Figure 9 and Figure 10 As shown, the hanging cap 123 is attached to the corresponding fastening post 81, meaning the fastening post 81 is snapped into the hanging cap 123. The left and right edges of the latch 1231 are respectively located in the corresponding slots 811. When the main unit 10 is wall-mounted, the fastening post 81 prevents the main unit 10 from moving downwards, and the slots 811 prevent the main unit 10 from moving forward, backward, left, or right. When the heater needs to be placed on the floor, first separate the hanging slot 801 from the wall nails, then install the stand 7, and then lower the mounting plate 8 so that the fastening post 81 detaches downwards from the hanging cap 123, thereby separating the mounting plate 8 from the main unit 10. This helps to keep the appearance of the heater simple when it is placed on the floor.
[0030] like Figure 1 As shown, the housing 1 includes a front housing 11 and a rear housing 12. The front housing 11 and the rear housing 12 are connected by corresponding screws. The air outlet 111 is specifically formed in the front housing 11. The hanging cap 123 is connected to the rear housing 12 as a whole. The clamping plate 122 is installed and connected to the rear housing 12, as shown. Figure 2 As shown, the rear shell 12 has an air inlet 121, and the position of the air inlet 121 corresponds to the impeller of the centrifugal fan 2.
[0031] When the heater is wall-mounted, the stand 7 can be left in place, so the frame tube 73 remains below the main unit 10. Users can hang towels on the frame tube 73. Since the air outlet 111 is located on the lower front side of the housing 1, and the front of the frame tube 73 is located below the air outlet 111, some of the warm air blown out from the air outlet 111 can be blown onto the towel. Moreover, the warm air flow blown out from the air outlet 111 can also drive the air around the towel, which helps the towel dry faster.
[0032] In summary, the heater of this invention can be used for both wall mounting and floor placement, making it more widely applicable.
