Description

Technical Field

[0001] The invention patent relates to the technical field of household appliances, and specifically to a folding drying rack applied to a heat pump hot air blower and a method of using the same. Background Art

[0002] A hot air blower is a household air conditioner that heats or cools the indoor air for air temperature regulation through heat exchange with the refrigerant in the machine. It absorbs cold air from the air inlet and exchanges heat with the heat exchanger in the machine, and exhausts hot air from the air outlet. When users want to use hot air to dry clothes, they can only place the clothes in other places for drying, or install additional brackets. When users use clothes to dry, the lack of a fixed bracket position will cause the clothes to dry slowly or not dry at all, which is very inconvenient. The additional bracket is troublesome to disassemble and install back and forth, which is not conducive to convenience.

[0003] In order to solve the above problems, the present invention provides a folding drying rack applied to a heat pump hot air blower and a method of using the same. Summary of the invention

DETAILED DESCRIPTION

[0026] The specific implementation of a folding drying rack applied to a heat pump hot air blower and a method of using the same provided by the present invention is further described in conjunction with the accompanying drawings and embodiments.

[0027] A folding drying rack for a heat pump hot air blower is used to be installed in a storage slot at the front end of a heat pump hot air blower housing. Specifically, it comprises a U-shaped support frame 1 and two sets of connecting frames; the left and right sides of the U-shaped support frame 1 are rotatably connected to the housing storage slot through a set of connecting frames.

[0028] like Figure 1 As shown, the U-shaped support frame 1 includes two left and right side frames and a middle frame located between the two side frames; the outer side walls of the two side frames close to the open ends are provided with a rotating shaft 11; the inner side walls of the two side frames close to the closed ends are symmetrically provided with two shaft seats 12.

[0029] Preferably, the connecting frame comprises a first connecting rod 2 and a second connecting rod 3. Figure 2 As shown, a connecting ring 21 is provided at one end of the first connecting rod 2, and the first connecting rod 2 is sleeved on the axle seat 12 through the connecting ring 21, thereby realizing relative rotation with the side frame of the U-shaped support frame 1; the other end of the first connecting rod 2 is rotatably connected to one end of the second connecting rod 3 through the first connecting shaft 22, and the other end of the second connecting rod 3 is provided with a second connecting shaft 31.

[0030] Preferably, a first axial hole is provided on the inner side wall of the open end of the storage groove corresponding to the position of the rotating shaft 11, and the open end of the U-shaped support frame 1 is rotatably connected to the first axial hole of the storage groove through the rotating shaft 11; the closed end of the U-shaped support frame 1 is a free end; a self-locking part 4 is provided on the inner side wall of the closed end of the storage groove corresponding to the position of the second connecting shaft 31; the second connecting shaft 31 of the second connecting rod 3 is slidably connected to the sliding groove 41 of the self-locking part 4.

[0031] like Figure 3 As shown, the self-locking member 4 includes a slide groove 41, a rectangular cavity 42 and a spring 43; the rectangular cavity 42 is arranged on the side of the slide groove 41 away from the second connecting rod 3, and the spring 43 is installed inside the rectangular cavity 42; preferably, an angular stopper 44 is arranged inside the slide groove 41; one end of the spring 43 is elastically connected to the side wall of the rectangular cavity 42 away from the second connecting rod 3, and the other end is elastically connected to the side of the angular stopper 44 away from the second connecting rod 3. It is worth noting here that in order to better meet the limiting function of the angular stopper 44 on the second rotating shaft 31, the spring 43 is made of a high-strength material with low elasticity, including but not limited to carbon steel, titanium alloy, aluminum alloy, etc.

[0032] Further preferably, the storage slot is adapted to the size of the U-shaped support frame 1; the sizes of the first connecting rod 2 and the second connecting rod 3 are both smaller than the side frame size of the U-shaped support frame 1, so that the folding drying rack can be completely stored inside the storage slot without taking up additional space.

[0033] Specifically, the method for using the folding drying rack includes:

[0034] When in use, the U-shaped support frame 1 is lifted upwards to drive the first connecting rod 2 and the second connecting rod 3 to unfold. At this time, the second connecting shaft 31 slides downward along the slide groove 41, and at the same time presses the angular limit block 44 downward to elastically deform the spring 43 until the second connecting shaft 31 slides to the bottom of the slide groove 41, at which time the spring 43 resets and drives the angular limit block 44 back to the initial position to complete the locking of the second connecting shaft 31; at this time, the first connecting rod 2 and the second connecting rod 3 are fully extended (that is, on the same straight line), and the middle frame of the U-shaped support frame 1 is horizontally located in front of the air outlet of the heat pump hot air blower, such as Figure 4 As shown;

[0035] After use, the U-shaped support frame 1 is folded downward, thereby driving the first connecting rod 2 and the second connecting rod 3 to be folded. At this time, the second connecting shaft 31 moves upward from the bottom of the slide groove 41, and at the same time gives an upward force to the angle limit block 44 to deform the spring 43. Until the second connecting shaft 31 moves to the top of the slide groove 44, the spring 43 is reset and drives the angle limit block 44 back to the initial position; at this time, the first connecting rod 2 and the second connecting rod 3 are all folded on the inner side of the side frame of the U-shaped support frame 1, and the drying rack can be folded as a whole and placed in the storage slot. Figure 5 shown.

[0036] The present invention provides a folding drying rack for a heat pump hot air blower, which has a simple structure and is easy to install and store. The heat pump hot air blower can be used to dry clothes conveniently without the need to set up a separate clothes drying rack. While saving space, it can also save the purchase cost of multiple household appliances, thereby achieving multiple uses of one item. In addition, the use of the hanging type drying clothes of the present invention avoids the problem of wrinkles compared to traditional dryers.
