Description

Technical Field

[0001] The utility model belongs to the field of heaters, and in particular relates to a direct-installed heater. Background Art

[0002] Heaters usually refer to equipment used for heating. The most commonly used heaters are electric heaters that use electricity as energy for heating. They are widely used in various civil and public buildings such as residential buildings, offices, hotels, shopping malls, hospitals, schools, train carriages, mobile heating, simple mobile homes, etc. After a long period of development, the structure of electric heaters tends to be fixed. Generally speaking, an electric heater includes a shell, a heating element and a fan arranged in the shell. The shell is installed in the wall, and the air outlet is exposed to the outside. The fan generates negative pressure to suck the air outside the shell into the shell and discharge the air from the air outlet after the air is heated by the heating element.

[0003] There are also many problems with existing heaters: when installing the heater, a positioning device is required to ensure a smooth installation process, such as a screw, but the pre-drilled holes in the wall are usually prone to dimensional deviations due to material problems, which makes it difficult to insert the screw and even causes structural deformation; in order to enhance the ventilation effect, many heaters adopt a multi-duct and multi-fan structure, but due to the fan distribution problem, the heater cannot simultaneously activate multiple fans to output warm air, that is, it can only blow air through the fan in the only duct connected to the outlet, resulting in idle waste of the fan.

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0031] Example

[0032] like Figure 1-Figure 6 , Figure 10-13As shown, this embodiment includes a host 1 with a combined air outlet on one side, a heater panel 2 arranged outside the combined air outlet, and a decorative panel 3 arranged on the side of the heater panel 2 away from the host 1. The host 1 is composed of an upper cover 4 and a lower cover 5 that can be fixed together by screws, and one end of the host 1 is provided with a ventilation port 6 formed by the upper cover 4 and the lower cover 5. The lower cover 5 is provided with a wind cavity 7, one end of which is connected to the ventilation port 6 and the other end is connected to the combined air outlet. The wind cavity 7 is divided into adjacent first air ducts 9 and second air ducts 10 by a partition 8 fixed in the lower cover 5. The combined air outlet includes an air outlet 11 arranged in the middle of one side of the lower cover 5, a lower first air inlet 12 and a lower second air inlet 13 arranged on the same side of the lower cover 5 and located on both sides of the air outlet 11, an upper first air inlet 14 arranged on the same side of the upper cover 4 and at a position corresponding to the lower first air inlet 12, and an upper second air inlet 15 arranged on one side of the upper cover 4 and at a position corresponding to the lower second air inlet 13. Among them, the upper first air inlet 14 and the lower first air inlet 12 are communicated with the first air duct 9 , and the upper second air inlet 15 , the lower second air inlet 13 and the air outlet 11 are communicated with the second air duct 10 .

[0033] like Figure 6-Figure 8 As shown, a first fan 16 is provided in the first air duct 9, and the first fan 16 is provided at one end of the first air duct 9 close to the upper first air inlet 14. Specifically, when the first fan 16 rotates in the reverse direction, the first air duct 9 is in a ventilation state, in which the air outside the main body is sucked into the first air duct 9 through the upper first air inlet 14 and the lower first air inlet 12, and is discharged through the ventilation port 6. A second fan 17 is provided in the second air duct 10, and the second fan 17 is provided at one end of the second air duct 10 close to the ventilation port 6. Specifically, when the second fan 17 rotates in the reverse direction, the second air duct 10 is in a ventilation state, in which the air outside the main body is sucked into the second air duct 10 through the upper second air inlet 15 and the lower second air inlet 13, and is discharged through the ventilation port 6.

[0034] like Figure 6-Figure 8 , Fig.14As shown, a swing blade 18 that can be driven to rotate by a motor is provided on the partition 8, and the swing blade 18 has two working states: ventilation and blowing. Specifically, the swing blade 18 is in a normal state when in the ventilation state, the motor does not work, and the first air duct 9 and the second air duct 10 are not connected; when the swing blade 18 enters the blowing state, the swing blade 18 rotates under the drive of the motor until it hits the edge of the air cavity 7, and the end of the first air duct 9 close to the combined air outlet is connected with the end of the second air duct 10 close to the combined air outlet. In this state, the first fan 16 and the second fan 17 rotate forward to form a negative pressure in the second air duct 10, and the air flow enters the main unit 1 through the ventilation port 6, and is blown out from the air outlet 11 through the second air duct 10 under the action of the first fan 16 and the second fan 17. In this embodiment, the swing blade 18 is used to change the connection state of the first air duct 9 and the second air duct 10, so that the heater can work through the first fan 16 and the second fan 17 at the same time in the blowing state, thereby improving the utilization rate of the fan and greatly improving the wind speed and flow rate that the heater can achieve.

[0035] like Figure 6-Figure 8 , Fig.10 As shown, a heating structure 19 with matching structure and a closable fan blade are provided at the air outlet 11. Specifically, the heating structure 19 heats the air blown out through the air outlet 11, and the fan blade can make the air outlet 11 in two states, closed and open, to match the different working states of the heater.

[0036] like Figure 1-Figure 5 , Fig. 9 As shown, a pair of ceiling hangers 20 are arranged between the main unit 1 and the heater panel 2, and the ceiling hangers 20 are fixed to the side of the main unit 1 with the combined air outlet through gaskets 21. The two ends of the ceiling hangers 20 are connected with screw hangers 22, and the screw hangers 22 are formed by extending outward from both ends of the ceiling hangers 20 and bending multiple times. Each screw hanger 22 has a T-groove 23 on the side away from the heater panel 2, and the bottom end opening of the T-groove 23 faces the opposite direction of the middle of the main unit 1. A positioning screw 24 is arranged in each screw hanger 22, and one end of the positioning screw 24 is vertically fixed to the inner end of the side close to the heater panel 2, and the rod body of the positioning screw 24 passes through the center of the T-groove 23. Specifically, when the main unit 1 is installed using the ceiling hanger 20 in conjunction with the positioning screw rods 24, the four positioning screw rods 24 are aligned with the pre-opened holes and then pushed in. During the pushing process, even if the four holes are somewhat different from the preset dimensions due to various reasons, the positioning screw rods 24 will self-adjust, that is, the rod body of the positioning screw rod 24 will undergo a certain displacement in the T-groove 23 to match the holes and grooves to achieve the best limiting effect.

[0037] like Figure 10-12As shown, the heater panel 2 is fixed to the host 1 through a plurality of connectors 25. The heater panel 2 is provided with a panel 1 air outlet 26 corresponding to the upper cover 4 and a panel 2 air outlet 27 corresponding to the lower cover 5. A blade 28 is provided between the panel 2 air outlet 27 and the air outlet 11 and the second air inlet. The blade 28 can be rotated by the motor to change the direction of the air flow blown out through the air outlet 11.

[0038] like Figure 10-12 As shown, the decorative plate 3 is installed outside the panel-air outlet 26.

A number of magnets 31 are distributed inside the panel-air outlet 26, and a metal adsorption point 32 corresponding to the magnet 31 is arranged on the side of the baffle facing the panel-air outlet 26. Specifically, when the decorative plate 3 is installed outside the panel-air outlet 26, the provided magnet 31 can produce an adsorption effect on the metal adsorption point to ensure the stability of the structure.

[0039] like Figure 10-12 As shown, a liquid crystal display device 33 is provided next to the panel air outlet 26 and is fixed on the side of the heater panel 2 facing the host 1.

[0040] like Figure 1-Figure 3 As shown, the outer surface of the upper cover 4 is inwardly recessed to form a plurality of equally spaced reinforcement grooves 34 , and the reinforcement grooves 34 can enhance the impact resistance of the structure of the host 1 .

[0041] The installation method of the above-mentioned direct-mounted heater includes the following steps:

[0042] 1) Drill holes and dig grooves on the ceiling board according to the size requirements of the main unit 1 and the positioning screw rod 24;

[0043] 2) According to the positioning point of the positioning screw rod 24, drill a hole on the corresponding cement top, insert the positioning screw rod 24 and fix it;
