Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a pitching electric heater with a counterweight. Background Art

[0002] The heater directly converts electrical energy or other chemical energy into thermal energy, and transfers heat through radiation, convection contact, etc., allowing users to move in a suitable temperature environment.

[0003] Depending on the heating medium and heating principle, weighted pitching electric heaters can be roughly divided into: gas weighted pitching electric heaters, electric heating weighted pitching electric heaters, boiler weighted pitching electric heaters, and electric wall-mounted boiler heating. Compared to traditional stoves and gas heating methods, electric heaters have more advantages, such as ease of use, low emissions, and space saving. Electric heaters are also relatively safe because they don't require gas, don't produce harmful gases, and are less prone to gas leaks. However, if an electric heating device tips over, the heating element may burn out due to a loss of heat dissipation, which can lead to electrical fires.

[0004] In addition, in order to prevent the heater from tipping over, the weight of the base is increased so that the center of gravity of the heater is concentrated on the base, making it less likely to tip over. Utility Model Content

[0005] Based on this, it is necessary to provide a pitching electric heater with a counterweight to address the above-mentioned problems of the pitching electric heater with a counterweight.

[0006] The present application discloses a pitching electric heater with a counterweight, comprising a housing assembly, a heating device, a control device, and a counterweight.

[0007] A housing assembly, comprising a base and a shell, wherein the shell is provided with an air inlet and an air outlet, and the shell can be flipped upside down and arranged on the base;

[0008] The control device, the heating device and the counterweight are mounted on the housing from top to bottom;

[0009] The connection between the base and the housing is adjacent to the heating device;

[0010] The counterweight is configured to increase the center of gravity of the bottom of the housing so as to keep the base upright when the housing is tilted relative to the base.

[0011] The present application discloses a pitch-tilt electric heater with a counterweight, which includes a shell assembly, a heating device, a control device and a counterweight. The shell assembly includes a base and an outer shell. The heating device, the control device and the counterweight are installed on the outer shell. The heating device can inhale airflow at the air inlet of the outer shell and discharge the airflow from the air outlet of the outer shell after heating. By flipping the outer shell relative to the base, the direction of the warm air of the pitch-tilt electric heater with a counterweight can be changed, which can adapt to heating needs at different heights. The control device, the heating device and the counterweight are distributed on the outer shell from top to bottom along the length direction of the outer shell, and the base and the outer shell are rotatably connected near the heating device. When the outer shell is flipped relative to the base, the counterweight at the bottom of the outer shell can offset the force of the control device at the top of the outer shell that causes the pitch-tilt electric heater with a counterweight to tip over, thereby avoiding the pitch-tilt electric heater with a counterweight from tipping over. The pitch-tilt electric heater with a counterweight based on the above design has a high weight requirement for the counterweight compared to the method of setting the counterweight on the base, which not only increases the manufacturing cost of the product, but also requires increased packaging and transportation costs.

[0012] In one embodiment, the base includes a bottom plate and a fixing bracket, the fixing bracket is arranged on the bottom plate, and the shell is rotatably connected to the fixing bracket.

[0013] In one embodiment, the fixing bracket is U-shaped.

[0014] In one embodiment, the fixing bracket is rotatably connected to the base.

[0015] The pitching electric heater with counterweight in the above embodiment further limits the fixed bracket to be rotatable relative to the base, so that the air outlet of the pitching electric heater with counterweight can be adjusted not only up and down, but also left and right to meet the needs of various scenarios.

[0016] In one embodiment, a rotation limiting structure is provided between the base and the shell, and the rotation limiting structure is configured to limit an inclination angle of the shell relative to the base.

[0017] In one embodiment, the shell is in the shape of an elongated strip.

[0018] The pitch-down electric heater with counterweight in the above embodiment further limits the outer shell to be in the shape of an elongated strip. By distributing the control device, the heating device and the counterweight from top to bottom along the length direction of the outer shell, and the connection between the base and the outer shell is close to the heating device, the counterweight only needs to overcome the force of the pitch-down electric heater with counterweight caused by the gravity of the top control device when the outer shell is tilted relative to the base, so that the weight requirement of the counterweight is not high, the rationality of the design is improved, and the cost is reduced.

[0019] In one embodiment, the heating device includes an air duct housing, a heating element, and a fan assembly. The heating element is located in the air duct housing, and the air duct housing and the fan assembly are horizontally distributed in the outer shell.

[0020] The pitch-type electric heater with counterweight in the above embodiment further defines that the heating element is installed in the air duct shell, the air duct shell and the fan assembly are horizontally distributed in the outer shell, and the connection between the outer shell and the base is close to the center of gravity of the heating device, so that the counterweight block only needs to overcome the force of the pitch-type electric heater with counterweight caused by the gravity of the top control device when the outer shell is tilted relative to the base, so that the weight requirement of the counterweight block is not high, the design rationality is improved, and the cost is reduced.

[0021] In one embodiment, the control device includes a human-computer interaction module and a control circuit board, and the control circuit board is electrically connected to the human-computer interaction module and the heating device respectively, and the human-computer interaction module and the control circuit board are both distributed on the top of the shell.

[0022] The weighted pitch electric heater in the above embodiment further limits the human-computer interaction module and the control circuit board to be installed on the top of the shell, so as to avoid requiring the user to squat or bend down to operate. Moreover, the air outlet of the weighted pitch electric heater is set in the middle of the shell to avoid the hot air flow discharged from the air outlet from affecting the human-computer interaction module and the control circuit.

[0023] In one embodiment, the shell assembly further includes a handle, which is disposed on the top of the shell.

[0024] The pitching electric heater with counterweight in the above embodiment is further limited to having a handle installed at the top of the shell. Based on the above design, the user's convenience is taken into consideration, so that the pitching electric heater with counterweight in this application can be easily moved to other positions as needed, thereby providing a more flexible way of use.

[0025] In one embodiment, the pitch electric heater with counterweight further includes an anti-dumping sensor, which is disposed on the base and electrically connected to the control device.

[0026] The weighted pitching electric heater described above further includes a base equipped with an anti-tilt sensor capable of detecting the device's tilt angle in real time. When the heater's tilt angle exceeds a set threshold, the sensor triggers a power-off mechanism, immediately shutting off power and preventing the device from continuing to operate, potentially leading to safety incidents.

[0036] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0037] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, for the purposes of describing the embodiments of the present application herein.

[0038] like Figures 1 to 4 As shown, this embodiment provides a pitch electric heater with a counterweight, comprising a housing assembly 10, a heating device 20, a control device 30, and a counterweight 40;

[0039] The housing assembly 10 includes a base 11 and a shell 12. The shell 12 is provided with an air inlet and an air outlet. The shell 12 can be turned upside down and arranged on the base 11.

[0040] The control device 30, the heating device 20 and the counterweight 40 are mounted on the housing 12 from top to bottom;

[0041] The connection between the base 11 and the housing 12 is adjacent to the heating device 20;

[0042] The counterweight 40 is configured to increase the center of gravity of the bottom of the housing 12 so as to keep the base 11 upright when the housing 12 is tilted relative to the base 11 .

[0043] The housing 12 may include a mounting cavity for mounting the control device 30, the heating device 20, and the counterweight 40, as well as an air inlet and an air outlet communicating with the mounting cavity. The inner wall or bottom of the housing 12 may be provided with a structure for mounting the counterweight 40, such as a mounting groove. The counterweight 40 may be directly inserted into the groove to securely mount the counterweight 40 to the housing 12. It should be noted that the counterweight 40 may be made of, but is not limited to, metal or non-metal materials. For example, the counterweight 40 may be stone.

[0044] The heating device 20 can be used to inhale air flow at the air inlet and introduce it into the heating device 20 for heating. The heated air flow is discharged through the air outlet, thereby providing heating needs for the user.

[0045] The housing 12 can be flipped up and down relative to the base 11 to adjust the direction of airflow. Specifically, the base 11 and the housing 12 are pivotally connected near the heater 20. Since the control device 30, heater 20, and counterweight 40 are arranged from top to bottom along the length of the housing 12, when the housing 12 is flipped relative to the base 11, the counterweight 40 at the bottom of the housing 12 can offset the force applied by the control device 30 at the top of the housing 12 that would cause the weighted pitch heater to tip over.

[0046] The pitching electric heater with counterweight in the above embodiment includes a shell assembly 10, a heating device 20, a control device 30 and a counterweight 40. The shell assembly 10 includes a base 11 and a shell 12. The heating device 20, the control device 30 and the counterweight 40 are installed on the shell 12. The heating device 20 can inhale air at the air inlet of the shell 12 and discharge the air from the air outlet of the shell 12 after heating the air. By flipping the shell 12 relative to the base 11, the warm air direction of the pitching electric heater with counterweight can be changed to adapt to heating needs at different heights. By controlling the control device 30, the heating device 20 and the counterweight 40, the warm air direction of the pitching electric heater with counterweight can be changed to adapt to heating needs at different heights. 0 are distributed on the shell 12 from top to bottom along the length direction of the shell 12, and the base 11 and the shell 12 are rotatably connected near the heating device 20. When the shell 12 is flipped relative to the base 11, the counterweight block 40 at the bottom of the shell 12 can offset the force of the control device 30 at the top of the shell 12 that causes the pitch electric heater with counterweight to tip over, thereby preventing the pitch electric heater with counterweight from tipping over. The pitch electric heater with counterweight based on the above design has a higher weight requirement than the method of setting the counterweight block 40 on the base 11, which not only increases the product manufacturing cost, but also increases the packaging cost and transportation cost.

[0047] like Figures 1 to 3 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the base 11 includes a bottom plate 111 and a fixing bracket 112 , the fixing bracket 112 is disposed on the bottom plate 111 , and the housing 12 is rotatably connected to the fixing bracket 112 .

[0048] The bottom plate 111 may be, but is not limited to, a metal shell or a non-metal shell. For example, the bottom plate 111 may be a plastic shell structure, and the bottom plate 111 may be cylindrical. A space for installing equipment may be formed inside the bottom plate 111.

[0049] Because the shell 12 is supported on the base plate 111 by the fixed bracket 112, and the shell 12 and the fixed bracket 112 can rotate relative to each other, when the shell 12 is flipped relative to the base 11, the gravity of the counterweight block 40 at the bottom of the shell 12 can partially or completely offset the force of the tilting of the electric heater with counterweight caused by the control device 30 at the top of the shell 12.

[0050] like Figure 1 and Figure 2 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the fixing bracket 112 is U-shaped.

[0051] The fixing bracket 112 may be U-shaped, with both ends of the fixing bracket 112 connected to the housing 12, thereby improving the stability of the connection between the housing 12 and the fixing bracket 112. In addition, it should be noted that the shape of the fixing bracket 112 may also be a square or oval shape.

[0052] In addition to the features of the above embodiment, this embodiment further defines that: the fixing bracket 112 is rotatably connected to the base 11 .

[0053] The above embodiment further defines that the fixing bracket 112 can rotate relative to the base 11, so that the air outlet of the pitch electric heater with counterweight can be adjusted not only up and down, but also left and right to meet the needs of various scenarios.

[0054] The fixed bracket 112 can be rotated with the base 11 manually or electrically. For example, the fixed bracket 112 and the base 11 are rotated electrically. Specifically, a drive assembly, a connecting rod, and a turntable are installed in the space formed in the base plate 111. The turntable is connected to the fixed bracket 112, and the two ends of the connecting rod are respectively connected to the turntable and the output end of the drive assembly. When the drive assembly rotates, the connecting rod drives the connecting rod to rotate, thereby realizing the electric rotation of the fixed bracket 112 relative to the base plate 111.

[0055] In addition to the features of the above embodiment, this embodiment further defines that: a rotation limiting structure is provided between the base 11 and the housing 12 , and the rotation limiting structure is configured to limit the tilt angle of the housing 12 relative to the base 11 .

[0056] The rotation limiting structure may include multiple positions, each corresponding to a different angle formed between the housing 12 and the base 11. When the housing 12 rotates relative to the base 11 to a certain position, the rotation limiting structure can maintain the housing 12 and the base 11 in a relatively stationary state in the absence of external force.

[0057] like Figure 1 and Figure 2 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the housing 12 is in the shape of an elongated strip.

[0058] The above embodiment further defines that the outer shell 12 is in the shape of an elongated strip. By distributing and installing the control device 30, the heating device 20 and the counterweight 40 from top to bottom along the length direction of the outer shell 12, and the connection between the base 11 and the outer shell 12 is close to the heating device 20, the counterweight 40 only needs to overcome the force of the pitch electric heater with counterweight that is tilted due to the gravity of the top control device 30 when the outer shell 12 is tilted relative to the base 11, so that the weight requirement of the counterweight 40 is not high, the rationality of the design is improved, and the cost is reduced.

[0059] like Figure 3 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further defines that: the heating device 20 includes an air duct housing 21, a heating element 22 and a fan assembly 23, the heating element 22 is located in the air duct housing 21, and the air duct housing 21 and the fan assembly 23 are horizontally distributed in the outer shell 12.

[0060] The above embodiment further defines that the heating element 22 is installed in the air duct housing 21, the air duct housing 21 and the fan assembly 23 are horizontally distributed in the outer shell 12, and the connection between the outer shell 12 and the base 11 is close to the center of gravity of the heating device 20, so that the counterweight block 40 only needs to overcome the force of the counterweight pitch electric heater tipping due to the gravity of the top control device 30 when the outer shell 12 is tilted relative to the base 11, so that the weight requirement of the counterweight block 40 is not high, the design rationality is improved, and the cost is reduced.

[0061] When powered, the heating element 22 heats the airflow entering the air duct housing 21, providing warmth to the user. For example, the heating element 22 may be a PTC. The fan assembly 23 is a blower mounted on the air duct housing 21, with the blower's outlet facing the air inlet of the air duct housing 21.

[0062] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further defines: the control device 30 includes a human-computer interaction module 31 and a control circuit board 32, the control circuit board 32 is electrically connected to the human-computer interaction module 31 and the heating device 20 respectively, and the human-computer interaction module 31 and the control circuit board 32 are both distributed on the top of the shell 12.

[0063] The above embodiment further stipulates that the human-computer interaction module 31 and the control circuit board 32 are both installed on the top of the shell 12, so as to avoid requiring the user to squat or bend down to operate. Moreover, the air outlet of the pitch electric heater with counterweight is set in the middle of the shell 12 to avoid the hot air flow discharged from the air outlet from affecting the human-computer interaction module 31 and the control circuit.

[0064] Among them, the human-computer interaction module 31 can be used to receive user instructions and display the current working information of the pitch electric heater with counterweight, and the control circuit board 32 can receive the input user instructions and output a control signal to control the heating device 20 or the drive component in the base 11 for the horizontal rotation of the fixed bracket 112. Exemplarily, the human-computer interaction module 31 can input user instructions through buttons, voice, touch screen, etc. Based on the fact that the human-computer interaction module 31 and the control circuit board 32 are installed at the top of the housing 12, it is not only convenient for users to operate and observe, but also keeps the human-computer interaction module 31 and the control circuit board 32 away from the air outlet to avoid being in a high temperature environment for a long time.

[0065] like Figure 1 and Figure 2 As shown, in addition to the features of the above embodiments, this embodiment is further defined as follows: the housing assembly 10 further includes a handle 13 , which is disposed on the top of the shell 12 .

[0066] The above embodiment further defines that a handle 13 is installed at the top of the shell 12. Based on the above design, the user's convenience is taken into consideration, so that the weighted pitch electric heater of the present application can be easily moved to other positions as needed, thereby providing a more flexible way of use.

[0067] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment is further defined as follows: it also includes an anti-dumping sensor 50 , the anti-dumping sensor 50 is arranged on the base 11 , and the anti-dumping sensor 50 is electrically connected to the control device 30 .

[0068] The above embodiment further provides that the base 11 is provided with an anti-tilt sensor 50 capable of detecting the tilt angle of the device in real time. When the tilt angle of the heater exceeds a set threshold, the sensor triggers a power-off mechanism, immediately cutting off the power supply, preventing the device from continuing to operate and preventing safety accidents caused by tilting.

[0069] The anti-dump sensor 50 can be used to detect whether the device has tipped over or fallen over, thereby automatically cutting off the power supply. Specifically, the anti-dump sensor 50 can be a photoelectric tilt switch, which uses optical principles to detect changes in the device body's normal state. Angle changes in the device body cause a small bead inside the switch to roll, causing contact with a metal terminal or changing the path of light, thereby causing conduction or non-conduction, thus controlling the connection or disconnection of the circuit.

[0070] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of this utility model patent shall be determined by the appended claims.
